Description

Technical Field

[0001] This utility model relates to the field of plastic particle screening technology, and in particular to a screening device for plastic particles. Background Technology

[0002] Screening is a crucial step in the production and processing of plastic granules, used to classify granules by size to meet the needs of different applications. Currently, vibrating screens are one of the commonly used screening devices, which use vibration to move plastic granules on a screen mesh, with smaller granules passing through the mesh openings for separation. However, existing vibrating screens have the following problems in practical use: due to the elasticity and lightweight nature of plastic granules, under the high-frequency vibration of the vibrating screen, the granules tend to bounce high, making it difficult for them to pass smoothly through the screen mesh openings. This not only reduces screening efficiency but also affects the screening effect, increasing operating and time costs. Furthermore, during the screening process, the falling plastic granules collide violently with the feeding components and collection container, generating a large amount of noise. This noise not only pollutes the working environment but may also negatively affect the hearing health of operators. Therefore, this application proposes a screening device for plastic granules to solve the above problems. Utility Model Content

[0003] The main objective of this invention is to provide a screening device for plastic granules, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A screening device for plastic granules includes a screening assembly, which is fixedly mounted on a support. A guide cone tube is fixedly mounted on the support and below the screening assembly. A blocking assembly is mounted on the screening assembly. The blocking assembly consists of a support plate, an internally threaded tube, a screw, an L-shaped base plate, an L-shaped rubber airbag, and an L-shaped high-elastic sponge pad. The internally threaded tube is fixedly inserted into the support plate, the screw is installed inside the internally threaded tube, the L-shaped base plate is rotatably connected to the screw, the L-shaped rubber airbag is fixedly mounted at one end of the L-shaped base plate, and the L-shaped high-elastic sponge pad is fixedly mounted at one end of the L-shaped rubber airbag. A guide noise reduction assembly is fixedly mounted inside the guide cone tube. The guide noise reduction assembly consists of a rubber cone tube, a support rod, and a conical rubber guide plate. The conical rubber guide plate is located inside the rubber cone tube, and the support rod connects the conical rubber guide plate and the rubber cone tube together.

[0006] Preferably, the screening assembly consists of a frame and a screen, with the screen fixedly installed on the lower inner wall of the frame.

[0007] Preferably, a feeding hopper is fixedly installed on the upper end of the frame on the screening component, and the frame is fixedly installed on the upper end of the support.

[0008] Preferably, the support plate on the blocking assembly is fixedly installed at the upper end of the frame, and the L-shaped base plate, L-shaped rubber airbag and L-shaped high-elastic sponge pad are movably installed inside the frame, with the L-shaped base plate, L-shaped rubber airbag and L-shaped high-elastic sponge pad all located above the screen.

[0009] Preferably, the rubber cone tube on the material guiding noise reduction assembly is fixedly installed on the inner wall of the material guiding cone tube, and there are four support rods, one end of which is fixedly connected to the inner wall of the rubber cone tube and the other end is fixedly connected to the outer wall of the conical rubber guide plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] (1) By setting a blocking component consisting of a support plate, an internal threaded tube, a screw, an L-shaped base plate, an L-shaped rubber airbag and an L-shaped high-elastic sponge pad on the screening component, the bouncing height of plastic particles during the screening process can be effectively limited, ensuring that the particles always move close to the screen, thereby improving screening efficiency and screening effect. At the same time, the L-shaped rubber airbag and the L-shaped high-elastic sponge pad can prevent a lot of noise from being generated when plastic particles collide with the blocking component.

[0012] (2) By setting a material guiding noise reduction component consisting of a rubber cone tube, a support rod and a conical rubber guide plate on the material guiding cone tube, the energy absorption characteristics of the rubber material are used to significantly reduce the noise generated by the collision between the plastic particles and the material guiding component when they fall. The material guiding noise reduction component can block the falling plastic particles, thereby slowing down the falling speed of the plastic particles and preventing the plastic particles from hitting the collection container below the material guiding cone tube at a high speed, further reducing noise, and ultimately improving the working environment and protecting the hearing health of the operators.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-5 As shown, a screening device for plastic granules includes a screening component 1, which is fixedly mounted on a support 2. A guide cone 3 is fixedly mounted on the support 2 below the screening component 1. A blocking component 4 is mounted on the screening component 1, which consists of a support plate 9, an internally threaded tube 10, a screw 11, an L-shaped base plate 12, an L-shaped rubber airbag 13, and an L-shaped high-elastic sponge pad 14. The internally threaded tube 10 is fixedly inserted into the support plate 9, and the screw 11 is installed inside the internally threaded tube 10. The L-shaped base plate 12 and the internally threaded tube 10 are fixedly mounted on the support plate 9. The screw 11 is rotatably connected, the L-shaped rubber airbag 13 is fixedly installed at one end of the L-shaped base plate 12, the L-shaped high-elastic sponge pad 14 is fixedly installed at one end of the L-shaped rubber airbag 13, and the material guiding cone tube 3 is fixedly installed with a material guiding noise reduction component 5. The material guiding noise reduction component 5 consists of a rubber cone tube 15, a support rod 16 and a conical rubber guide plate 17. The conical rubber guide plate 17 is located inside the rubber cone tube 15, and the support rod 16 connects the conical rubber guide plate 17 and the rubber cone tube 15 together. The screening component 1 consists of a frame 7 and a screen 8. The screen 8 is fixedly installed on the lower inner wall of the frame 7. The upper end of the frame 7 on the screening assembly 1 is fixedly installed with a discharge hopper 6. The frame 7 is fixedly installed on the upper end of the support 2. When screening plastic granules, the plastic granules to be screened are first poured into the discharge hopper 6. The granules enter the frame 7 of the screening assembly 1 through the discharge hopper 6 and fall onto the screen 8. After the equipment is started, the screening assembly 1 begins to vibrate, and the plastic granules move on the screen 8. At this time, the blocking component 4 limits the bouncing range of the granules, ensuring that the granules move close to the screen 8. To improve screening efficiency, plastic particles smaller than the mesh size of screen 8 will pass through screen 8 and fall into the lower guide cone tube 3. The conical rubber guide plate 17 and rubber cone tube 15 of the guide noise reduction component 5 will block the plastic particles, thereby slowing down the falling speed of the particles and absorbing the collision energy, significantly reducing noise. Finally, the particles will fall into the collection container placed below the guide cone tube 3, while plastic particles larger than the mesh size of screen 8 will roll down the inclined surface of screen 8 and eventually fall into the collection container placed below.

[0021] Specifically, the support plate 9 on the blocking component 4 is fixedly installed on the upper end of the frame 7. The L-shaped base plate 12, the L-shaped rubber airbag 13, and the L-shaped high-elastic sponge pad 14 are movably installed inside the frame 7, and the L-shaped base plate 12, the L-shaped rubber airbag 13, and the L-shaped high-elastic sponge pad 14 are all located above the screen 8. The distance between the L-shaped high-elastic sponge pad 14, the L-shaped rubber airbag 13 and the screen 8 can be adjusted by rotating the screw 11 in the internal threaded tube 10. By setting the blocking component 4, which consists of the support plate 9, the internal threaded tube 10, the screw 11, the L-shaped base plate 12, the L-shaped rubber airbag 13 and the L-shaped high-elastic sponge pad 14 on the screening component 1, the bouncing height of the plastic particles during the screening process can be effectively limited, ensuring that the particles always move close to the screen 8, thereby improving the screening efficiency and screening effect. At the same time, the L-shaped rubber airbag 13 and the L-shaped high-elastic sponge pad 14 can prevent the plastic particles from colliding with the blocking component 4 and generating a lot of noise.

[0022] Specifically, the rubber cone tube 15 on the material guiding and noise reduction component 5 is fixedly installed on the inner wall of the material guiding cone tube 3. There are four support rods 16, one end of which is fixedly connected to the inner wall of the rubber cone tube 15 and the other end is fixedly connected to the outer wall of the conical rubber guide plate 17. The bottom diameter of the conical rubber guide plate 17 should be larger than the bottom diameter of the rubber cone tube 15, so as to ensure that the falling plastic particles can be blocked and slowed down by the conical rubber guide plate 17 or the rubber cone tube 15, effectively preventing the plastic particles from falling directly from the screening component 1 into the collection container below the material guiding cone tube 3. By installing a material guiding noise reduction component 5 on the material guiding cone tube 3, consisting of a rubber cone tube 15, a support rod 16, and a conical rubber guide plate 17, the energy absorption characteristics of the rubber material are used to significantly reduce the noise generated by the collision between the falling plastic particles and the material guiding cone tube 3. In addition, the material guiding noise reduction component 5 can block the falling plastic particles, thereby slowing down the falling speed of the plastic particles and preventing the plastic particles from hitting the collection container below the material guiding cone tube 3 at a high speed, further reducing noise, and ultimately improving the working environment and protecting the hearing health of the operators.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
