Description

A PC / ABS plastic particle proportioning and weighing device Technical Field

[0001] This utility model relates to the field of plastic production, and in particular to a quantitative weighing device for PC / ABS plastic particles. Background Technology

[0002] A search of Chinese patents revealed publication number CN209014108U, a plastic granule weighing device. This invention addresses the challenge of accurately measuring and quantitatively controlling the weight of plastic granules in existing technologies. The key technical features include a frame with a storage tank for storing plastic granules and a transparent quantitative tank located below it. A discharge pipe connected to the bottom of the storage tank is fixedly connected, and a first control valve is installed on the discharge pipe. The quantitative tank has several vertically marked graduations corresponding to different weight values. A receiving pipe connected to the bottom of the quantitative tank is fixedly connected, and a second control valve is installed on the receiving pipe. The device is simple to operate and easy to control.

[0003] Existing quantitative weighing devices lack mixing capabilities. Generally, they can only weigh plastic granules, which then need to be mixed using a mixing device. This is cumbersome, increases workload, reduces proportioning efficiency, and makes it difficult to adjust the discharge direction. Typically, the discharge pipe of such devices has a fixed direction; changing it requires disassembling, adjusting, and reinstalling the pipe, a troublesome process that increases workload, reduces efficiency, and is inconvenient to use. To address these issues, we propose a quantitative weighing device for PC / ABS plastic granules. Summary of the Invention

The rotation of the first rotating shaft 5 and the second rotating shaft 9 drives the stirring rod 11 to rotate, thus mixing the plastic particles. This method can achieve the purpose of stirring, reduce the workload, and improve practicality.

[0034] Referring to Figures 1 and 2, the quantitative weighing and feeding mechanism 3 includes a hopper 18. A second motor 19 is bolted to the top of the hopper 18. The output end of the second motor 19 extends into the interior of the hopper 18 and is connected to an auger 20 via a coupling. A weighing sensor 21 is bolted between the hopper 18 and the top of the mixing box 1. A Chengying HZC-TD1 type weighing sensor is used. A controller 22 is bolted to the surface of the mixing box 1. A Sanying Precision Control PMC100 controller is used. By setting up the quantitative weighing and feeding mechanism 3, the raw materials are weighed, which facilitates quantitative feeding and convenient proportioning.

[0035] Referring to Figures 1 and 2, the bottom of the mixing box 1 is connected to an electric valve 23, and the electric valve 23 is rotatably sleeved with the inner wall of the discharge pipe 12. By setting the electric valve 23, it is convenient to discharge materials.

By setting the protective shells 25, the first motor 4 and the second motor 19 are protected.

[0037] Example 2:

[0038] Referring to Figures 1, 2, 4, and 6, a discharge pipe 12 is provided at the bottom of the mixing box 1. A fixing plate 13 is fixedly sleeved on the surface of the mixing box 1. A locking rod 14 is slidably sleeved on the inner wall of the fixing plate 13. A limiting plate 15 is fixedly sleeved on the surface of the locking rod 14. A spring 16 is provided between the limiting plate 15 and the inner wall of the fixing plate 13. An adjustment hole 17 is provided at the top of the discharge pipe 12, and the locking rod 14 is locked with the adjustment hole 17.

[0042] Brief description of the operation: Plastic granules are placed into the feed hopper 18. The weighing sensor 21 weighs the plastic granules and transmits the weight value to the controller 22, which records it. Then, the second motor 19 is turned on, which drives the auger 20 to rotate. The auger 20 adds the plastic granules into the mixing tank 1. During the addition process, the weighing sensor 21 detects the weight in real time. When the added amount reaches the set value, the controller 22 will cause the second motor 19 to rotate, stopping the feeding, thus achieving the purpose of quantitative weighing. The first motor 4 rotates, driving the first rotating shaft 5 to rotate, which in turn drives the transmission... Rotating the drive rod 6 drives the gear ring 7 to rotate, which in turn drives the gear 8 to rotate. The gear 8 then drives the second rotating shaft 9 to rotate, and the rotation of the second rotating shaft 9 and the first rotating shaft 5 drives the stirring rod 11 to rotate. The stirring rod 11 then stirs and mixes the raw materials, thus achieving the purpose of mixing. Moving the pull block 24 causes the locking rod 14 to move, disengaging it from the adjustment hole 17. After rotating the discharge pipe 12 to the desired direction, the pull block 24 is released, and the locking rod 14 engages with the adjustment hole 17 under the action of the spring 16, fixing it in place and completing the adjustment, thereby facilitating the adjustment of the discharge direction.
