Description

Technical Field

[0001] The invention belongs to the technical field of plastic conveying, in particular to a conveying device and process with a crushing function for producing impact-resistant composite engineering plastics. Background Art

[0002] Impact-resistant composite engineering plastics are a type of engineering plastic materials with excellent impact resistance. They can maintain structural integrity and stability when subjected to external impact. During the production process of impact-resistant composite engineering plastics, waste or unqualified composite engineering plastic materials may be generated. Through the conveying device, these unqualified plastic materials can be conveyed to another processing link to achieve the continuity and automation of the production process. Moreover, before conveying the unqualified plastic materials, the plastic materials can be crushed into small pieces to facilitate subsequent processing or recycling.

[0003] The patent with announcement number CN210594048U discloses a plastic pellet conveyor capable of removing debris, including a carrying plate and a collecting box, self-locking rollers are arranged on both the left and right sides of the bottom of the carrying plate, and support plates are arranged on both the front and rear sides of the carrying plate, the rear side of the motor is connected to the conveyor belt device through the motor shaft, and the conveyor belt device is arranged between the support plates, the collecting box is arranged below the conveyor belt device, and the collecting box is fixed on the inner side of the support plate, a debris box is arranged on the lower side of the discharge port, and the debris box is arranged on the carrying plate, a feeding device is arranged between the tops of the support plates, and a feeding port is opened on the feeding device, and a baffle plate is penetrated on the left side of the bottom of the feeding device, a fixed block is fixed on the bottom of the feeding device, and the fixed block is arranged on the upper side of the baffle plate, and the left side of the baffle plate is connected to the fixed block through a latch. In the plastic pellet conveyor capable of removing debris, the conveying and impurity removal of plastic pellets are carried out simultaneously, thereby improving work efficiency.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The plastic particles are transported to a designated location via a conveyor belt. However, in some cases, different types of plastic particles need to be transported, and in order to avoid mixing different types of plastic particles together, they are transported in batches. At the same time, in order to facilitate the subsequent processing of different types of plastic particles, multiple receiving devices are provided at the end of the conveyor belt, and the receiving devices are usually provided with a discharge port to accurately classify the fallen plastic particles. In the above technical solution, when the plastic particles fall from the end of the conveyor belt, the orientation is relatively single, and it is difficult for the plastic particles to accurately fall into the designated discharge port. They may enter other discharge ports, which is not conducive to the classification of the plastic particles. In addition, when the distribution area of ​​the plastic particles on the conveyor belt is larger than the area of ​​the discharge port, some of the plastic particles will fall to the outside of the discharge port, thereby affecting the conveying work.

[0018] A conveying process with a crushing function for producing impact-resistant composite engineering plastics, comprising the following specific steps:

[0019] S1. When the unloading opening area of ​​the receiving device at the end of the conveyor belt is large, and the plastic particles to be transported are of the same type and do not need to be transported in batches, the unqualified plastic materials are first placed between the two crushing rollers in the crushing box, and then the two crushing rollers are driven to rotate in different directions at the same time to crush the plastic materials. After being crushed into plastic particles, they fall onto the conveyor belt, and as the conveyor belt runs, the plastic particles are moved to the receiving device, and the conveying of the plastic particles can be realized;

[0020] S2. When the plastic material is crushed, the dust generated during the crushing process can be sucked into the dust collection box by using a vacuum cleaner, thereby avoiding the dust from affecting the surrounding workers;

[0021] S3. When the discharge port area of ​​the material receiving device at the end of the conveyor belt is small and its width is smaller than the width of the conveyor belt, the adjusting ring can be driven to move to the bottom of the crushing box before the crushing work, and then the plastic material is crushed. The crushed plastic particles will fall into the cavity formed by the gathering plates 1 and 2, and then the gathering plates 1 and 2 are driven to move at the same time to adjust the volume of the cavity formed by the gathering plates 1 and 2, so as to push the plastic particles within the range of the gathering plates 1 and 2, so that the plastic particles can be gathered, and the distribution area of ​​the plastic particles is reduced, so that the distribution area of ​​the plastic particles is smaller than the area of ​​the discharge port;

[0022] S4, then drive the slider and the conveyor belt to move at the same time, so that the gathered plastic particles move to the discharge port of the receiving device at the end of the conveyor belt, and when the gathering plates 1 and 2 change the distribution area of ​​the plastic particles, only the distribution area of ​​the plastic particles is changed to be slightly smaller than the area of ​​the discharge port, so that the plastic particles will not fall outside the discharge port, and the situation that the plastic particles fall slowly due to the small cavity area of ​​the gathering plates 1 and 2 can be avoided;

[0023] S5. When the gathering plates 1 and 2 are adjusted, the anti-stuck strips 1 and 2 will also move, and the anti-stuck strips 2 will slide in the groove of the anti-stuck strips 1 to adapt to the area changes of the gathering plates 1 and 2. When plastic particles fall from between the gathering plates 1 and 2, multiple anti-stuck strips 1 and 2 are driven to descend at the same time, and the plastics adhered to and stuck on the gathering plates 1 and 2 are pushed so that they can fall normally, thereby avoiding the plastic particles being squeezed by the gathering plates 1 and 2, resulting in the plastic particles being stuck at the angle of the gathering plates 1 or adhering to the surfaces of the gathering plates 1 and 2, ensuring the discharge amount of the plastic particles, and avoiding the plastic particles between the gathering plates 1 and 2 being mixed with subsequent plastic particles of different types, thereby affecting the classification effect of the plastic particles.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The conveying device and process with crushing function for the production of impact-resistant composite engineering plastics described in the present invention crushes the plastic material by driving two crushing rollers to rotate in different directions at the same time. After crushing into plastic particles, it is convenient for subsequent processing or recycling.

[0026] 2. The conveying device and process with crushing function for the production of impact-resistant composite engineering plastics described in the present invention can use the gathering and pushing mechanism to push the plastic particles within the range of the gathering plate 1 and the gathering plate 2, so that the plastic particles can be gathered, and the distribution area of ​​the plastic particles is reduced, so that the distribution area of ​​the plastic particles is smaller than the area of ​​the discharge port, and then the gathered plastic particles are driven to move to the discharge port of the receiving device at the end of the conveyor belt, so as to avoid the situation that some plastic particles fall outside the discharge port because the distribution area of ​​the plastic particles on the conveyor belt is larger than the area of ​​the discharge port. The situation of the lower part is avoided, thereby ensuring the normal conveying work. Moreover, when the gathering plates 1 and 2 change the distribution area of ​​the plastic particles, it is only necessary to change the distribution area of ​​the plastic particles to be slightly smaller than the area of ​​the discharge port. This ensures that the plastic particles will not fall outside the discharge port, and avoids the situation that the plastic particles fall slowly due to the small cavity area of ​​the gathering plates 1 and 2. Moreover, when multiple discharge ports are provided at the end of the conveyor belt at the same time, and different types of plastic particles need to fall into the designated discharge ports in turn, the plastic particles drive the adjustment ring to move horizontally after being gathered. , the plastic particles in the range of the gathering plates 1 and 2 can be pushed to adjust the position of the plastic particles on the conveyor belt so that the plastic particles are aligned with the specified discharge port. After the adjustment is completed, the gathering plates 1 and 2 move with the conveyor belt again, so that the plastic particles can fall accurately into the specified discharge port, thereby avoiding the situation where the plastic particles enter other discharge ports, which is conducive to the classification and processing of the plastic particles. In addition, when the gathering plates 1 and 2 are adjusted, the anti-stuck strips 1 and 2 will also move to adapt to the area of ​​the gathering plates 1 and 2. When the plastic particles fall from between the gathering plates one and two, the anti-stuck strips one and two are driven down, so that the plastics adhering to and stuck at the gathering plates one and two can be pushed and can fall normally, thereby preventing the plastic particles from being squeezed by the gathering plates one and two, causing the plastic particles to be stuck at the angle of the gathering plate one, or adhering to the surface of the gathering plates one and two, thereby ensuring the discharge amount of the plastic particles and preventing the plastic particles between the gathering plates one and two from being mixed with subsequent plastic particles of different types, thereby affecting the classification effect of the plastic particles.

[0027] 3. The conveying device and process with crushing function for the production of impact-resistant composite engineering plastics described in the present invention can use a vacuum cleaner to suck the dust generated during the crushing process into a dust collecting box when the plastic material is crushed, thereby avoiding the dust from affecting surrounding workers.

One side of the rear end surface of the crushing box 28 is fixedly connected to a motor 6 27, and the output end of the motor 6 27 is fixedly connected to one side of the crushing roller 6.

[0044] A plurality of connecting rods 17 are rotatably provided on the upper end surface of the adjusting ring 11 , a connecting rod 2 18 is rotatably provided on one end of the connecting rod 17 , and one end of the connecting rod 28 is rotatably connected to one end of the adjusting rod 23 .

[0045] One end of the connecting rod 17 is fixedly connected to a gear 16, and the upper end surface of the adjusting ring 11 is rotatably provided with a gear ring 12, and the gear blocks on the inner ring of the gear ring 12 are meshed with the gear 16. One side of the upper end surface of the adjusting ring 11 is fixedly connected to a motor 2 15, and the output end of the motor 2 15 is fixedly connected to one end of the connecting rod 17.

[0046] The gathering plate 13 is also provided with a telescopic anti-stuck component for preventing plastic particles from being stuck between the gathering plate 13 and the gathering plate 2 14. The telescopic anti-stuck component includes an anti-stuck strip 24 slidably connected to one side of the gathering plate 13, and an anti-stuck strip 25 is fixedly connected to one side of the anti-stuck strip 24. The anti-stuck strip 25 is inserted into the groove of the adjacent anti-stuck strip 24 and is slidably connected.

[0047] One end of the anti-stuck strip 24 is threadedly connected to the threaded rod 3 22, and both ends of the threaded rod 3 22 are rotatably set on the gathering plate 13. One side of the upper end of the gathering plate 13 is fixedly connected to the motor 5 21, and the output end of the motor 5 21 is fixedly connected to one end of the threaded rod 3 22.

[0048] Specifically, when the existing plastic pellet conveyor is in use, the plastic pellets are conveyed to a designated location through the conveyor belt 1. However, in some cases, different types of plastic pellets need to be conveyed, and in order to avoid mixing different types of plastic pellets together, batch conveying is adopted. At the same time, in order to facilitate the subsequent processing of different types of plastic pellets, multiple receiving devices are provided at the end of the conveyor belt 1, and the receiving devices are usually provided with a discharge port to accurately classify the fallen plastic pellets. However, in the prior art, when the plastic pellets fall from the end of the conveyor belt 1, the orientation is relatively single, and the plastic pellets are difficult to accurately fall into the designated discharge port, and may enter the remaining discharge ports, which is not conducive to the classification of the plastic pellets. Moreover, when the distribution area of ​​the plastic pellets on the conveyor belt 1 is larger than the area of ​​the discharge port, some of the plastic pellets will fall outside the discharge port, thereby affecting the conveying work.

[0049] Therefore, in order to solve the above problem, when the unloading port area of ​​the receiving device at the end of the conveyor belt 1 is large, and the plastic particles to be transported are of the same type and do not need to be transported in batches, the unqualified plastic material is first placed between the two crushing rollers 6 in the crushing box 28, and then the motor 6 27 is used to drive the crushing roller 6 on one side to rotate, and under the cooperation of the two gears 26, the two crushing rollers 6 are rotated in different directions at the same time to crush the plastic material. After being crushed into plastic particles, they fall onto the conveyor belt 1, and as the conveyor belt 1 runs, the plastic particles are moved to the receiving device, and the conveying of the plastic particles can be realized;

[0050] When the unloading port area of ​​the material receiving device at the end of the conveyor belt 1 is small and its width is smaller than the width of the conveyor belt 1, before the crushing work, the motor 4 20 can be used to drive the threaded rod 1 4 to rotate, so that the adjusting ring 11 moves to the bottom of the crushing box 28, and then the plastic material is crushed. The crushed plastic particles will fall into the cavity formed by the gathering plate 13 and the gathering plate 2 14, and then the motor 2 15 is used to drive the connecting rod 1 17 on one side to rotate, and under the rotation of the gear 1 16, the gear ring 12 is rotated, so that multiple connecting rods 1 17 and connecting rods 2 18 can be rotated at the same time. When the connecting rod 1 17 and the connecting rod 2 18 rotate at the same time, multiple adjusting rods 23 slide radially on the adjusting ring 11 at the same time, so that the gathering plate 13 and the gathering plate 2 14 can be moved at the same time, and the gathering plate 2 14 slides in the groove of the adjacent gathering plate 13 to adjust the volume of the cavity formed by the gathering plate 13 and the gathering plate 2 14. The plastic particles within the range of the gathering plate 1 13 and the gathering plate 2 14 are pushed to gather the plastic particles, reduce the distribution area of ​​the plastic particles, and make the distribution area of ​​the plastic particles smaller than the area of ​​the discharge port. At this time, the slider 7 and the conveyor belt 1 are driven to move at the same time to move the gathered plastic particles to the discharge port of the receiving device at the end of the conveyor belt 1, thereby avoiding the situation that part of the plastic particles fall to the outside of the discharge port due to the distribution area of ​​the plastic particles on the conveyor belt 1 being larger than the area of ​​the discharge port, thereby ensuring the normal progress of the conveying work, and when the gathering plates 1 13 and the gathering plates 2 14 change the distribution area of ​​the plastic particles, they only need to change the distribution area of ​​the plastic particles to be slightly smaller than the area of ​​the discharge port, thus ensuring that the plastic particles will not fall to the outside of the discharge port, and avoiding the situation that the plastic particles fall slowly due to the small cavity area of ​​the gathering plates 13 and the gathering plates 2 14;

[0051] When multiple discharge ports are provided at the end of the conveyor belt 1, and different types of plastic particles need to be dropped into the designated discharge ports in sequence, the above-mentioned gathering of the plastic particles is repeated. Moreover, after the gathering, the motor 1 8 is used to drive the threaded rod 2 9 to rotate, so that the adjustment ring 11 moves horizontally, and the plastic particles in the range of the gathering plate 1 13 and the gathering plate 2 14 can be pushed to adjust the position of the plastic particles on the conveyor belt 1 so that the plastic particles are aligned with the designated discharge port. After the adjustment is completed, the gathering plate 1 13 and the gathering plate 2 14 move with the conveyor belt 1 again, so that the plastic particles can be accurately dropped into the designated discharge port, thereby avoiding the situation where the plastic particles enter other discharge ports, which is conducive to the classification and processing of the plastic particles.

[0052] Since the plastic particles will be squeezed when they are pushed by the gathering plates 13 and 14, the plastic particles may be stuck at the angle of the gathering plates 13 or adhere to the surfaces of the gathering plates 13 and 14, which not only affects the discharge amount of the plastic particles, but may also be mixed with subsequent different types of plastic particles, thereby affecting the classification effect of the plastic particles. Therefore, in order to avoid this problem, when the gathering plates 13 and 14 are adjusted, the anti-stuck strips 1 24 and 25 will also move, and the anti-stuck strips 25 will slide in the grooves of the anti-stuck strips 1 24 to adapt to the area changes of the gathering plates 13 and 14. When the plastic particles fall from between the gathering plates 13 and 14, the motor is used to The five 21 drives the threaded rod three 22 to rotate, so that multiple anti-stuck strips 1 24 and anti-stuck strips 25 can be lowered at the same time. Moreover, since the anti-stuck strips 1 24 and anti-stuck strips 25 are in contact with the inner surfaces of the gathering plates 1 13 and the gathering plates 2 14, the plastics adhering to and stuck on the gathering plates 1 13 and the gathering plates 2 14 can be pushed so that they can fall normally, thereby avoiding the plastic particles being squeezed by the gathering plates 1 13 and the gathering plates 2 14, resulting in the plastic particles being stuck at the angle of the gathering plates 1 13 or adhering to the surfaces of the gathering plates 1 13 and the gathering plates 2 14, thereby ensuring the discharge amount of the plastic particles and avoiding the plastic particles between the gathering plates 1 13 and the gathering plates 2 14 from being mixed with subsequent plastic particles of different types, thereby affecting the classification effect of the plastic particles.

[0053] In this embodiment, Figure 7 As shown, a dust box 19 is fixedly connected to one side of the upper end surface of the support frame 5, and a dust collector 29 is connected and fixedly connected to one side of the upper end of the dust box 19, and a dust suction port 30 is connected to the air inlet end of the dust collector 29.

[0054] Specifically, when the plastic material is crushed, the dust generated during the crushing process can be sucked into the dust collecting box 19 by the vacuum cleaner 29, thereby preventing the dust from affecting surrounding workers.

[0055] A conveying process with a crushing function for producing impact-resistant composite engineering plastics, comprising the following specific steps:

[0056] S1. When the unloading port area of ​​the receiving device at the end of the conveyor belt 1 is large, and the plastic particles to be transported are of the same type and do not need to be transported in batches, the unqualified plastic material is first placed between the two crushing rollers 6 in the crushing box 28, and then the two crushing rollers 6 are driven to rotate in different directions at the same time to crush the plastic material. After being crushed into plastic particles, they fall onto the conveyor belt 1, and as the conveyor belt 1 runs, the plastic particles are moved to the receiving device, and the conveying of the plastic particles can be realized;

[0057] S2. When the plastic material is crushed, the dust generated during the crushing process can be sucked into the dust collecting box 19 by using the vacuum cleaner 29, thereby avoiding the dust from affecting the surrounding workers;

[0058] S3. When the discharge port area of ​​the material receiving device at the end of the conveyor belt 1 is small and its width is smaller than the width of the conveyor belt 1, the adjusting ring 11 can be driven to move to the bottom of the crushing box 28 before the crushing work, and then the plastic material is crushed, and the crushed plastic particles will fall into the cavity formed by the gathering plate 1 13 and the gathering plate 2 14, and then the gathering plate 1 13 and the gathering plate 2 14 are driven to move at the same time to adjust the volume of the cavity formed by the gathering plate 1 13 and the gathering plate 2 14, so as to push the plastic particles within the range of the gathering plate 1 13 and the gathering plate 2 14, so that the plastic particles can be gathered, and the distribution area of ​​the plastic particles is reduced, so that the distribution area of ​​the plastic particles is smaller than the area of ​​the discharge port;

[0059] S4, then drive the slider 7 and the conveyor belt 1 to move at the same time, so that the gathered plastic particles move to the discharge port of the receiving device at the end of the conveyor belt 1, and when the gathering plates 13 and 14 change the distribution area of ​​the plastic particles, they only need to change the distribution area of ​​the plastic particles to be slightly smaller than the area of ​​the discharge port, so that the plastic particles will not fall outside the discharge port, and the situation that the plastic particles fall slowly due to the small cavity area of ​​the gathering plates 13 and 14 can be avoided;

[0060] S5. When the gathering plates 1 13 and 14 are adjusted, the anti-stuck strips 1 24 and 25 will also move, and the anti-stuck strips 25 will slide in the grooves of the anti-stuck strips 1 24 to adapt to the area changes of the gathering plates 1 13 and 14. When the plastic particles fall from between the gathering plates 1 13 and 14, multiple anti-stuck strips 1 24 and 25 are driven to descend at the same time, and the plastics adhered to and stuck on the gathering plates 1 13 and 14 are pushed so that they can fall normally, thereby avoiding the plastic particles being squeezed by the gathering plates 1 13 and 14, resulting in the plastic particles being stuck at the angle of the gathering plates 1 13 or adhering to the surfaces of the gathering plates 1 13 and 14, ensuring the discharge amount of the plastic particles, and avoiding the plastic particles between the gathering plates 1 13 and 14 being mixed with subsequent plastic particles of different types, thereby affecting the classification effect of the plastic particles.

[0061] Working principle: When the unloading port area of ​​the receiving device at the end of the conveyor belt 1 is large, and the plastic particles to be transported are of the same type and do not need to be transported in batches, the unqualified plastic materials are first placed between the two crushing rollers 6 in the crushing box 28, and then the motor 6 27 is used to drive the crushing roller 6 on one side to rotate, and with the cooperation of the two gears 26, the two crushing rollers 6 are rotated in different directions at the same time to crush the plastic materials. After being crushed into plastic particles, they fall onto the conveyor belt 1, and as the conveyor belt 1 runs, the plastic particles are moved to the receiving device, and the conveying of the plastic particles can be realized. When the plastic material is crushed, the plastic particles are crushed by the motor 6 27. The dust collector 29 can suck the dust generated during the crushing process into the dust collecting box 19, thereby preventing the dust from affecting the surrounding workers; and when the unloading port area of ​​the material receiving device at the end of the conveyor belt 1 is small and the width is smaller than the width of the conveyor belt 1, before the crushing work, the motor 4 20 can be used to drive the threaded rod 1 4 to rotate, so that the adjustment ring 11 moves to the bottom of the crushing box 28, and then the plastic material is crushed. The crushed plastic particles will fall into the cavity formed by the gathering plate 1 13 and the gathering plate 2 14, and then the motor 2 15 is used to drive the connecting rod 1 17 on one side to rotate, and under the rotation of the gear 1 16, the gear ring 12 is rotated. , that is, the plurality of connecting rods 17 and connecting rods 2 18 can be rotated at the same time. When the connecting rods 17 and connecting rods 2 18 rotate at the same time, the plurality of adjusting rods 23 slide radially on the adjusting ring 11 at the same time, so that the gathering plates 1 13 and the gathering plates 2 14 can be moved at the same time, and the gathering plates 2 14 slide at the grooves of the adjacent gathering plates 1 13 to adjust the volume of the cavity formed by the gathering plates 1 13 and the gathering plates 2 14, so as to push the plastic particles within the range of the gathering plates 1 13 and the gathering plates 2 14, so that the plastic particles can be gathered, and the distribution area of ​​the plastic particles can be reduced, so that the distribution area of ​​the plastic particles is smaller than the area of ​​the discharge port. At this time, the slider 7 and the conveyor are driven simultaneously. The conveyor belt 1 moves so that the gathered plastic particles move to the discharge port of the receiving device at the end of the conveyor belt 1, which can avoid the situation that part of the plastic particles fall outside the discharge port due to the distribution area of ​​the plastic particles on the conveyor belt 1 being larger than the area of ​​the discharge port, thereby ensuring the normal progress of the conveying work, and when the gathering plates 13 and 14 change the distribution area of ​​the plastic particles, they only need to change the distribution area of ​​the plastic particles to be slightly smaller than the area of ​​the discharge port, which can ensure that the plastic particles will not fall outside the discharge port, and avoid the situation that the plastic particles fall slowly due to the small cavity area of ​​the gathering plates 13 and 14;When multiple discharge ports are provided at the end of the conveyor belt 1, and different types of plastic particles need to be dropped into the designated discharge ports in sequence, the above-mentioned gathering of the plastic particles is repeated. Moreover, after the gathering, the motor 1 8 is used to drive the threaded rod 2 9 to rotate, so that the adjustment ring 11 moves horizontally, and the plastic particles in the range of the gathering plate 1 13 and the gathering plate 2 14 can be pushed to adjust the position of the plastic particles on the conveyor belt 1 so that the plastic particles are aligned with the designated discharge port. After the adjustment is completed, the gathering plate 1 13 and the gathering plate 2 14 move with the conveyor belt 1 again, that is, The plastic particles can be accurately dropped into the designated discharge port, thereby preventing the plastic particles from entering other discharge ports, which is beneficial for the classification of the plastic particles. Since the plastic particles are squeezed when they are pushed by the gathering plates 13 and 14, the plastic particles may be stuck at the angle of the gathering plates 13 or adhere to the surfaces of the gathering plates 13 and 14, which not only affects the discharge amount of the plastic particles, but may also be mixed with subsequent different types of plastic particles, thereby affecting the classification effect of the plastic particles. In order to avoid this problem, when the gathering plates 13 and 14 are adjusted, the anti-stuck strips 1 24 and 25 will also move, and the anti-stuck strips 25 will slide in the grooves of the anti-stuck strips 1 24 to adapt to the area changes of the gathering plates 13 and 14. When the plastic particles fall from between the gathering plates 13 and 14, the motor 5 21 drives the threaded rod 3 22 to rotate, so that the plurality of anti-stuck strips 1 24 and 25 can be simultaneously lowered. In addition, since the anti-stuck strips 1 24, 25 and the gathering plates 13 and 14 are adjusted, the anti-stuck strips 1 24 and 25 can be adjusted to the area changes of the gathering plates 13 and 14. The inner surface of the second plate 14 is fitted, so the plastic adhered and stuck at the gathering plate 13 and the second gathering plate 14 can be pushed to make it fall normally, thereby avoiding the situation that the plastic particles are squeezed by the gathering plate 13 and the second gathering plate 14, and the plastic particles are stuck at the angle of the gathering plate 13 or adhered to the surface of the gathering plate 13 and the second gathering plate 14, ensuring the feeding amount of the plastic particles, and avoiding the situation that the plastic particles between the gathering plate 13 and the second gathering plate 14 are mixed with the subsequent different types of plastic particles, affecting the classification effect of the plastic particles. ;
