Plastic pellet dispensing device

Abstract

This utility model discloses a plastic granule batching device, belonging to the field of plastic granule processing technology. It aims to solve the problem of the lack of a simultaneous pretreatment mechanism for multiple plastic materials in existing technologies. When faced with multi-component materials that are prone to moisture absorption and clumping, electrostatic adhesion, or irregular particle shapes, the undispersed materials directly enter the mixing system, easily leading to particle agglomeration and "clumping." These agglomerated particles are difficult to disperse completely during the mixing process, resulting not only in uneven material distribution within the mixing device and the formation of numerous "mixing dead zones," but also in local component concentrations that are too high or too low due to differences in the dispersion state of different materials, severely affecting the uniformity of the final mixture. The device includes a main body, with a pretreatment mechanism mounted around the central periphery of the upper part of the main body, and a mixing mechanism jointly mounted in the middle and upper part of the main body. The pretreatment mechanism includes a feeding rack, which is distributed around the upper periphery of the main body.

Description

Technical Field

[0001] This utility model belongs to the field of plastic granule processing technology, specifically relating to a plastic granule batching device. Background Technology

[0002] Plastic granules are a common raw material used to manufacture various plastic bags, buckets, basins, toys, furniture, stationery, and other household items and plastic products. They are usually in spherical form, which makes them easy to package and transport. At the same time, different types of plastic granules can be mixed in a certain proportion according to actual needs to generate mixed plastic granules with different properties for use as production raw materials. This process requires a plastic granule mixing device.

[0003] Current plastic pellet batching equipment lacks a simultaneous pretreatment mechanism for multiple plastic materials. When faced with multi-component materials that are prone to moisture absorption and clumping, have electrostatic adhesion, or have irregular particle shapes, the undispersed materials directly enter the mixing system, which easily leads to the formation of "clumps" due to particle agglomeration. These agglomerated particles are difficult to disperse completely during the mixing process, which not only causes uneven distribution of materials in the mixing device and forms a large number of "mixing dead zones", but also causes local component concentrations to be too high or too low due to differences in the dispersion state of different materials, which seriously affects the uniformity of the final mixture.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this invention, workers pre-feed various materials required for production through the feeding ports above multiple feeding racks. Then, the first motor is started, and the transmission rod at the end of the motor rotates accordingly. The two first synchronous pulleys around the transmission rod also rotate. Since the first rotating rods in the middle of the feeding racks on both sides of the transmission rod are also equipped with first synchronous pulleys, and these first synchronous pulleys are meshed and driven by first synchronous belts, the first rotating rods on both sides can rotate at the same speed as the transmission rod. At the same time, one of the first synchronous pulleys on each of the two first rotating rods meshes with the second synchronous pulleys around the second rotating rods in the other two feeding racks through the first synchronous belts. In this way, the rotating rods in the four feeding racks can achieve the same speed. Finally, the dispersing rods set on the four rotating rods can disperse and pre-treat the materials fed into the feeding racks to prevent the materials from clumping and affecting the subsequent production process.

[0018] This invention allows various plastic granular materials that have undergone pre-dispersion treatment to collect and fall into the main body of the batching device as the electric V-shaped ball valve at the bottom of each feeding rack is opened. At this time, the second motor is started, causing the third rotating rod to rotate. The stirring rods with staggered arrangement around the periphery of the third rotating rod can efficiently mix these evenly dispersed and non-clumping materials, greatly shortening the mixing time of the batching device and indirectly improving the overall energy efficiency of the production line.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a plastic granule dispensing device, the structural diagram of which is shown below. Figures 1 to 4As shown, the system includes a main body 1. A pretreatment mechanism 2 is mounted around the central periphery of the upper part of the main body 1. A mixing mechanism 3 is also mounted together in the middle and upper part of the main body 1. The pretreatment mechanism 2 includes feeding racks 21, which are distributed around the upper periphery of the main body 1. Dust covers 22 are provided above the multiple feeding racks 21. A pretreatment assembly 23 is jointly installed in the middle of the multiple feeding racks 21 and above the main body 1. The pretreatment assembly 23 includes a first motor 231, which is mounted on one side of the upper part of the main body 1. The output end of the first motor 231 is connected to a transmission rod 232. First rotating rods 233 are installed in the middle of the feeding racks 21 on both sides of the first motor 231. Two... A first synchronous pulley 234 is provided, and a first synchronous belt 235 is fitted around the periphery of the first synchronous pulley 234. Two other feed racks 21 have second rotating rods 236 installed in their middle sections, and a second synchronous pulley 237 is fixed around one section of the second rotating rod 236. A second synchronous belt 238 is fitted around the periphery of the second synchronous pulley 237 opposite to the first synchronous pulley 234. Four feed racks 21 are arranged along the periphery of the upper middle section of the main body 1. The first rotating rods 233 and second rotating rods 236 within the four feed racks 21 are synchronously connected by the first synchronous pulley 234, the first synchronous belt 235, the second synchronous pulley 237, and the second synchronous belt 238, respectively. Multiple first rotating rods 233 and second rotating rods 236... A dispersing rod 239 is provided around a section of the perimeter. The dispersing rod 239 is equidistantly distributed along a section of the first rotating rod 233 and the second rotating rod 236. Multiple feeding racks 21 are equipped with electric V-type ball valves 24 at their bottom ends. A guide guard 25 is fixed to the upper section of each feeding rack 21. The guide guard 25 is fixed inside the upper section of the feeding rack 21, and the slot formed between the guide guard 25 and the feeding rack 21 serves as the feeding inlet. Workers pre-feed various materials required for production through the feeding inlets above the multiple feeding racks 21. Then, the first motor 231 is started, and the transmission rod 232 at the end of the motor rotates accordingly. Two first synchronous pulleys 234 around the transmission rod 232 also rotate. Because the transmission rod 232... The first rotating rod 233 in the middle of the feed rack 21 on both sides is also provided with a first synchronous wheel 234 around its periphery. These first synchronous wheels 234 are meshed and driven by a first synchronous belt 235. Therefore, the first rotating rods 233 on both sides can rotate at the same speed as the transmission rod 232. At the same time, one of the first synchronous wheels 234 on each of the two first rotating rods 233 meshes with the second synchronous wheels 237 around the second rotating rods 236 in the other two feed racks 21 through the first synchronous belt 235. In this way, the rotating rods in the four feed racks 21 can achieve the same speed. Finally, the dispersing rods 239 distributed on the four rotating rods can disperse and pre-treat the material fed into the feed rack 21 to prevent the material from clumping and affecting the subsequent production process.

[0027] The mixing mechanism 3 includes a gathering frame 31, which is fixed inside the main body 1. The gathering frame 31 is cylindrical and fixed inside the main body 1. A second motor 32 is installed at the top center of the main body 1, and the output end of the second motor 32 is connected to a third rotating rod 33. A stirring rod 34 is distributed around a section of the third rotating rod 33. The stirring rods 34 are staggered and equidistantly distributed along a section of the third rotating rod 33. Various plastic granular materials that have undergone pre-dispersion treatment will be collected and fall into the main body 1 of the batching device as the electric V-shaped ball valve 24 at the bottom of each feeding rack 21 is opened. At this time, the second motor 32 is started to rotate the third rotating rod 33. The stirring rods 34 staggered around a section of the third rotating rod 33 can efficiently mix these evenly dispersed and non-clumping materials, greatly shortening the mixing time of the batching device and indirectly improving the overall production line efficiency.

[0028] Working principle: Workers pre-feed various materials required for production through the feeding ports above multiple feeding racks 21. Then, the first motor 231 is started, and the transmission rod 232 at the motor end rotates accordingly. Two first synchronous pulleys 234 around the transmission rod 232 also rotate. Since the first rotating rods 233 in the middle of the feeding racks 21 on both sides of the transmission rod 232 are also equipped with first synchronous pulleys 234, and these first synchronous pulleys 234 are meshed and driven by a first synchronous belt 235, the first rotating rods 233 on both sides can rotate at the same speed as the transmission rod 232. Simultaneously, one of the first synchronous pulleys 234 on each of the two first rotating rods 233 is connected to the second rotating rods 233 in the other two feeding racks 21 via the first synchronous belt 235. The second synchronous wheel 237 around the moving rod 236 engages, so that the rotating rods in the four feeding racks 21 can rotate at the same speed. Finally, the dispersing rods 239 distributed on the four rotating rods can disperse the materials fed into the feeding racks 21 to prevent the materials from clumping and affecting the subsequent production process. After the various plastic granules have undergone the pre-dispersing treatment, they will be collected and fall into the main body 1 of the batching device as the electric V-shaped ball valve 24 at the bottom of each feeding rack 21 is opened. At this time, the second motor 32 is started to make the third rotating rod 33 rotate. The stirring rods 34 distributed around the third rotating rod 33 can efficiently mix these evenly dispersed and non-clumped materials, greatly shortening the mixing time of the batching device and indirectly improving the overall production line energy efficiency.
