Instead of weighing each dose, the machine uses interchangeable stainless steel volumetric cups mounted on a rotating turntable \u2014 product fills each cup by gravity, a leveling brush sweeps off the excess, and the cup discharges directly into the forming tube below. This volumetric principle delivers consistent fill volumes at very high speed with minimal mechanical complexity.<\/p>\r\n\r\n        <p>The turntable dosing system is the simplest and most cost-effective metering method for uniform, free-flowing granules where exact weight is less critical than consistent volume and high throughput. Typical products include sugar, salt, rice, beans, seeds, spice blends, pet treats, and small hardware. Two model sizes \u2014 SW-320D (bag width up to 150 mm, fill weight 10\u2013100 g) and SW-420D (bag width up to 200 mm, fill weight 100\u20131,000 g) \u2014 cover everything from single-serve sachets to retail-size pouches. Both models run on 220V single-phase power with Siemens PLC and touch screen control.<\/p>\r\n      <\/div>\r\n\r\n      <div class=\"sw-stat-stack\">\r\n        <div class=\"sw-stat-block\">\r\n          <p class=\"sw-stat-label\">Packing Speed<\/p>\r\n          <p class=\"sw-stat-number\">30\u2013100 <span class=\"sw-stat-unit\">bags \/ min<\/span><\/p>\r\n        <\/div>\r\n        <div class=\"sw-stat-block\">\r\n          <p class=\"sw-stat-label\">Fill Range<\/p>\r\n          <p class=\"sw-stat-number\">10\u20131,000 <span class=\"sw-stat-unit\">g<\/span><\/p>\r\n        <\/div>\r\n        <div class=\"sw-stat-block\">\r\n          <p class=\"sw-stat-label\">Machine Weight<\/p>\r\n          <p class=\"sw-stat-number is-accent\">350 <span class=\"sw-stat-unit\">kg<\/span><\/p>\r\n        <\/div>\r\n      <\/div>\r\n    <\/div>\r\n\r\n    <!-- Full spec table -->\r\n    <div class=\"sw-table-wrapper\" style=\"margin-top:48px\">\r\n      <table class=\"sw-data-table\">\r\n        <thead>\r\n          <tr>\r\n            <th>Parameter<\/th>\r\n            <th>SW-320D<\/th>\r\n            <th>SW-420D<\/th>\r\n          <\/tr>\r\n        <\/thead>\r\n        <tbody>\r\n          <tr><th>Roll Film Width<\/th><td>\u2264320 mm<\/td><td>\u2264420 mm<\/td><\/tr>\r\n          <tr><th>Bag Length<\/th><td>80\u2013200 mm<\/td><td>80\u2013300 mm<\/td><\/tr>\r\n          <tr><th>Bag Width<\/th><td>45\u2013150 mm<\/td><td>80\u2013200 mm<\/td><\/tr>\r\n          <tr><th>Fill Weight Range<\/th><td>10\u2013100 g<\/td><td>100\u20131,000 g<\/td><\/tr>\r\n          <tr><th>Packing Speed<\/th><td>30\u2013100 bags\/min<\/td><td>30\u201370 bags\/min<\/td><\/tr>\r\n          <tr><th>Dosing System<\/th><td colspan=\"2\">Rotary turntable with interchangeable volumetric cups<\/td><\/tr>\r\n          <tr><th>Bag Format<\/th><td colspan=\"2\">3-Side Seal \/ Back Seal \/ Gusset (from roll film)<\/td><\/tr>\r\n          <tr><th>Sealing Type<\/th><td colspan=\"2\">Vertical back seam + horizontal cross-seal<\/td><\/tr>\r\n          <tr><th>Control System<\/th><td colspan=\"2\">Siemens PLC + Siemens HMI touch screen<\/td><\/tr>\r\n          <tr><th>Contact Material<\/th><td colspan=\"2\">SUS304 Stainless Steel<\/td><\/tr>\r\n          <tr><th>Total Power<\/th><td>3.5 kW<\/td><td>3.5 kW<\/td><\/tr>\r\n          <tr><th>Voltage<\/th><td colspan=\"2\">220V \u00b7 50\/60 Hz (customizable)<\/td><\/tr>\r\n          <tr><th>Air Consumption<\/th><td colspan=\"2\">0.6\u20131.2 m\u00b3\/min<\/td><\/tr>\r\n          <tr><th>Machine Weight<\/th><td>~350 kg<\/td><td>~500 kg<\/td><\/tr>\r\n          <tr><th>Dimensions (L\u00d7W\u00d7H)<\/th><td>1,300 \u00d7 1,000 \u00d7 1,800 mm<\/td><td>1,500 \u00d7 1,200 \u00d7 2,200 mm<\/td><\/tr>\r\n        <\/tbody>\r\n      <\/table>\r\n    <\/div>\r\n\r\n    <!-- Component overview image -->\r\n    <div style=\"margin-top:48px;text-align:center\">\r\n      <img decoding=\"async\" src=\"https:\/\/www.shengweimachine.com\/wp-content\/uploads\/2024\/02\/SW-320D-420D-Collar-Type-Measure-Cups-Packing-Machine-Detail.webp\"\r\n           alt=\"SW-320D\/420D collar type measure cups packing machine detail \u2014 forming collar, Siemens touch screen, turntable cup dosing system, and film roll frame\"\r\n           width=\"1000\" height=\"600\"\r\n           loading=\"lazy\"\r\n           style=\"max-width:100%;height:auto;border-radius:var(--sw-radius-md)\">\r\n      <p style=\"margin-top:12px;font-size:0.88rem;color:var(--sw-text-soft)\">SW-420D key components: triangular forming collar, Siemens HMI touch screen, turntable measure cup dosing system, and rear film roll frame.<\/p>\r\n    <\/div>\r\n\r\n    <div class=\"sw-spec-cta\">\r\n      <a href=\"javascript:void(0)\"\r\n         onclick=\"if(typeof elementorProFrontend!=='undefined'){elementorProFrontend.modules.popup.showPopup({id:840})}\"\r\n         class=\"sw-btn-primary\">Request Full Datasheet<\/a>\r\n      <a href=\"https:\/\/wa.me\/8618125112025?text=Hello%2C+please+send+me+the+full+datasheet+for+the+SW-320D%2F420D+collar+type+measure+cups+packing+machine.\" class=\"sw-btn-secondary\" target=\"_blank\" rel=\"noopener\">Send via WhatsApp<\/a>\r\n    <\/div>\r\n\r\n  <\/div>\r\n<\/section>\r\n\r\n\r\n<section class=\"sw-section\">\r\n  <div class=\"sw-shell\">\r\n    <div class=\"sw-section-head-left\">\r\n      <span class=\"sw-eyebrow\">Application Scenarios<\/span>\r\n      <h2 class=\"sw-section-title\" style=\"text-align:left\">Recommended Configurations by Product<\/h2>\r\n      <p>The SW-320D\/420D is optimized for uniform, free-flowing granules where volumetric cup dosing provides the best cost-to-speed ratio.

A servo motor pulls the film through dancer rollers that maintain constant tension. An automatic film-end stop halts the machine when the roll runs out, preventing unsealed bags.

As the turntable rotates, each stainless steel measure cup fills by gravity. A nylon leveling brush sweeps excess product off the top of the cup to ensure a consistent fill volume. When a cup reaches the discharge position above the forming tube, it opens and releases the product directly into the bag below. Cup volume is fixed per set \u2014 changing the fill volume requires swapping to a different cup size (a 5-minute change). This volumetric dosing method is the fastest and simplest metering option for uniform granules.<\/p>\r\n      <\/div>\r\n\r\n      <div class=\"sw-workflow-step\">\r\n        <img decoding=\"async\" src=\"https:\/\/www.shengweimachine.com\/wp-content\/uploads\/2024\/02\/Finished-Product.webp\"\r\n             alt=\"Sealing and cutting step \u2014 horizontal sealing jaws create top and bottom seals, knife cuts finished sachet on SW-320D\/420D\"\r\n             width=\"120\" height=\"120\" loading=\"lazy\">\r\n        <p class=\"sw-workflow-num\">04<\/p>\r\n        <h3 class=\"sw-workflow-title\">Horizontal Sealing, Coding &amp; Cutting<\/h3>\r\n        <p class=\"sw-workflow-text\">After each fill, horizontal sealing jaws clamp across the tube to create the top seal of the filled bag and the bottom seal of the next bag simultaneously. Jaw temperature, dwell time, and pressure are independently adjustable per film type via the HMI. A date printer (standard) codes batch number and expiry date onto each sachet. A cutting knife then severs the finished sachet \u2014 or, for connected strip packs, a perforating knife creates tear lines between bags instead of cutting them apart.<\/p>\r\n      <\/div>\r\n\r\n

Typical products include sugar, salt, rice, beans, lentils, couscous, seeds (sunflower, sesame, pumpkin), small candy, pet kibble, small biscuits, spice blends, tea granules, washing powder, and small hardware parts (screws, bolts). The product must flow freely by gravity into the volumetric cups \u2014 sticky, clumping, or highly irregular products are not suitable. For those, use a weigher-based system.\r\n        <\/div>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>\r\n          <h3>How does the turntable volumetric cup dosing system work?<\/h3>\r\n          <span class=\"sw-acc-icon\"><\/span>\r\n        <\/summary>\r\n        <div class=\"sw-acc-body\">\r\n          Product flows from the top hopper into a rotating turntable that contains multiple stainless steel volumetric cups. As the turntable rotates, each cup fills by gravity. A motor-driven nylon leveling brush sweeps across the top of each cup to remove excess product, ensuring a consistent fill level. When a cup reaches the discharge position directly above the forming tube, it opens and the product drops through a funnel into the bag below. The fill volume is determined by the physical size of the cup \u2014 no electronics, no load cells, no calibration required. This is the simplest and most reliable dosing mechanism available.\r\n        <\/div>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>\r\n          <h3>How accurate is volumetric cup dosing compared to a weigher?<\/h3>\r\n          <span class=\"sw-acc-icon\"><\/span>\r\n        <\/summary>\r\n        <div class=\"sw-acc-body\">\r\n          Volumetric cup dosing measures volume, not weight. If your product has consistent density and uniform piece size (sugar, salt, rice), the weight per cup is very consistent \u2014 typically within \u00b12\u20133% of target weight. For less uniform products (mixed seeds, variable-size kibble), variance increases because the same volume may contain slightly different weights. If you need \u00b11 g weight accuracy (e.g. for pre-packaged weight regulations), use a weigher-based machine such as the SW-420A multi-head weigher or the SW-320C linear weigher.\r\n        <\/div>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>\r\n          <h3>What is the difference between the SW-320D and SW-420D?<\/h3>\r\n          <span class=\"sw-acc-icon\"><\/span>\r\n        <\/summary>\r\n        <div class=\"sw-acc-body\">\r\n          The two models differ in bag size capacity and machine footprint.

The SW-420D handles bag widths up to 200 mm and fill weights of 100\u20131,000 g at up to 70 bags\/min \u2014 designed for retail-size pouches. It weighs 500 kg and stands 2.2 m tall.

To change fill volume, you swap the cups on the turntable \u2014 a 5-minute manual operation, no tools required. ShengWei supplies a set of cups matched to your target fill weight(s) with each machine. If you need a new fill volume later, we manufacture and ship additional cup sets on request. Bag length is changed digitally on the HMI touch screen, effective on the next cycle.\r\n        <\/div>\r\n      <\/details>\r\n\r\n      <details>\r\n        <summary>\r\n          <h3>Can the machine produce connected strip packs?<\/h3>\r\n          <span class=\"sw-acc-icon\"><\/span>\r\n        <\/summary>\r\n        <div class=\"sw-acc-body\">\r\n          Yes.
