Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic granule processing technology, specifically to a screening device for plastic granule processing. Background Technology
[0002] The particle size (i.e., particle fineness) of plastic granules is a key parameter in plastic product processing, affecting not only the stability and efficiency of the processing technology but also directly determining the performance and quality of the final product. Therefore, to avoid mixing plastic granules of different sizes during processing, it is necessary to use a screening device to separate the plastic granules of different sizes.
[0003] In existing technologies, screening devices typically use a screening screen to sieve materials, which then flow directly out of the discharge port. However, the wide opening of the discharge port makes collection difficult, and materials easily spill onto the ground during collection, resulting in poor collection efficiency. A screening device for plastic granule processing is needed to solve these problems. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a screening device for processing plastic granules to solve the problems mentioned in the background technology. This utility model has a reasonable structure, convenient material collection, and good collection effect.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a screening device for processing plastic granules, comprising:
[0006] The shell has a feeding channel at the top and a screening screen and a guide plate arranged downwards from top to bottom inside the shell. The side wall of the shell has a discharge port at a position corresponding to the screening screen and the guide plate.
[0007] The side wall of the shell is provided with a triangular guide plate for covering each of the discharge ports. The side of the triangular guide plate away from the shell is provided with an arc portion. A triangular guide groove is opened at the top of the triangular guide plate. A through groove is opened on the side of the triangular guide plate close to the shell for connecting the discharge port and the triangular guide groove. A discharge pipe connected to the triangular guide groove is opened at the bottom of the triangular guide plate at a position corresponding to the arc portion.
[0008] The arc portions of the adjacent triangular guide plates are symmetrically distributed.
[0009] Furthermore, the lower side of the inner wall of the triangular guide channel is provided with a downwardly sloping surface, which is located below the discharge port.
[0010] Furthermore, an extension plate extends from the side of the triangular guide plate near the housing, and a fastening bolt is provided at the connection between the extension plate and the housing.
[0011] Furthermore, the top of the triangular guide plate is provided with an embedding groove that communicates with the triangular guide channel, and a cover plate is provided inside the embedding groove.
[0012] Furthermore, the top of the triangular guide plate is provided with multiple connecting grooves that communicate with the embedded groove, and the side wall of the cover plate extends with a connecting block that matches the connecting groove at the corresponding position. The connecting block is provided with a mounting bolt at the connection point between it and the triangular guide plate.
[0013] Furthermore, a support base is provided below the housing, a buffer assembly is provided at the connection between the support base and the housing, and a vibration motor is provided at the bottom of the housing.
[0014] Furthermore, the buffer assembly includes fixed blocks symmetrically arranged on opposite side walls of the housing, a protrusion is provided at the top of the support base corresponding to the fixed block, and a buffer spring is provided between the protrusion and the fixed block.
[0015] Furthermore, the top of the support base is symmetrically provided with multiple threaded rods, the bottom of the threaded rods is provided with a support plate, and the side wall of the threaded rods is provided with a nut located above the support base.
[0016] The beneficial effects achieved by the present invention using the above structure are as follows:
[0017] This invention allows sieved plastic granules to flow from the outlet into the channel of a triangular guide plate. The material then flows along the triangular guide plate to the arc part and is finally discharged from the outlet pipe. This prevents the material from splashing onto the ground during collection, facilitates the collection operation, and enhances the collection effect. Attached Figure Description

[0024] 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.
[0025] like Figure 1 As shown, this utility model provides a technical solution: a screening device for processing plastic granules, comprising:
[0026] The shell 1 has a feed channel 2 at the top and a screening screen 13 and a guide plate 12 arranged downwards from top to bottom inside the shell 1. The side wall of the shell 1 is provided with a discharge port 101 at the corresponding positions of the screening screen 13 and the guide plate 12.
[0027] The side wall of the shell 1 is provided with a triangular guide plate 3 for covering each discharge port 101. The side of the triangular guide plate 3 away from the shell 1 is provided with an arc portion 31. A triangular guide groove 32 is opened at the top of the triangular guide plate 3. A through groove 33 is opened on the side of the triangular guide plate 3 close to the shell 1 for connecting the discharge port 101 and the triangular guide groove 32. A discharge pipe 4 connected to the triangular guide groove 32 is opened at the bottom of the triangular guide plate 3 at the position corresponding to the arc portion 31.
[0028] The arc portions 31 of adjacent triangular guide plates 3 are symmetrically distributed. This design allows the screened plastic granules to flow from the outlet 101 into the channel 33 of the triangular guide plate 3. The material then flows along the triangular guide channel 32 to the arc portion 31, and finally exits from the discharge pipe 4. This prevents material from splashing onto the ground during collection, facilitating material collection and enhancing the collection effect. The symmetrical distribution of the arc portions 31 of adjacent triangular guide plates 3 ensures that the discharge pipes 4 at the bottom of adjacent triangular guide plates 3 are in different positions, enabling simultaneous collection of materials from the screening screen 13 and the guide plate 12. An inclined plate is provided on the upper side of the inner wall of the shell 1. The lower end of the inclined plate is located above the upper end of the screening screen 13, and the inclined plate is directly below the feed channel 2, facilitating the screening of plastic granules from the upper end to the lower end of the screening screen 13.
[0029] Reference Figure 2 and Figure 3 The lower side of the inner wall of the triangular guide channel 32 is provided with a downward sloping surface 321, which is located below the discharge port 101. This design allows the material to flow along the lower side of the inner wall of the triangular guide channel 32 to the arc portion 31 and then flow out from the discharge pipe.
[0030] Reference Figure 2 and Figure 4 An extension plate 34 extends from the side of the triangular guide plate 3 near the housing 1, and a fastening bolt 341 is provided at the connection between the extension plate 34 and the housing 1. This design improves the stability of the connection between the triangular guide plate 3 and the housing 1 through the extension plate 34 and the fastening bolt 341.
[0031] Reference Figure 3 and Figure 4 The top of the triangular guide plate 3 has an embedded groove 35 that communicates with the triangular guide channel 32, and a cover plate 5 is installed inside the embedded groove 35. This design allows for easy observation of the material flow through the cover plate 5, while preventing material from splashing onto the ground during collection; a force-applying rod is installed at the top of the cover plate 5.
[0032] Reference Figure 4 The top of the triangular guide plate 3 has multiple connecting grooves 36 that communicate with the embedded grooves 35. A connecting block 51, matching the connecting groove 36, extends from the side wall of the cover plate 5 at a position corresponding to the connecting groove 36. A mounting bolt 52 is provided at the connection point between the connecting block 51 and the triangular guide plate 3. This design, through the mounting bolt 52 and the connecting block 51, improves the stability of the connection between the cover plate 5 and the triangular guide plate 3.
[0033] Reference Figure 1 and Figure 2A support base 11 is provided below the housing 1, and a buffer assembly 6 is provided at the connection between the support base 11 and the housing 1. A vibration motor 10 is provided at the bottom of the housing 1. This design, through the vibration motor 10 and the buffer assembly 6, facilitates the vibration of the housing 1, thereby accelerating the screening speed of the screening screen 13 on the plastic granular material.
[0034] Reference Figure 1 The buffer assembly 6 includes fixed blocks 61 symmetrically arranged on opposite side walls of the housing 1. A protrusion 63 is provided on the top of the support base 11 at a position corresponding to the fixed blocks 61. A buffer spring 62 is provided between the protrusion 63 and the fixed blocks 61. This design uses the buffer spring 62 to conveniently buffer the fixed blocks 61 on the housing 1. When the vibration motor 10 is working, it drives the housing 1 to vibrate.
[0035] Reference Figure 2 Multiple threaded rods 9 are symmetrically arranged through the top of the support base 11, and a support plate 7 is provided at the bottom of the threaded rods 9. Nuts 8 are provided on the side walls of the threaded rods 9 above the support base 11. This design facilitates the support of the support base 11 through the threaded rods 9 and the support plate 7.
[0036] Reference Figures 1-4 As an embodiment of this utility model: when it is necessary to screen plastic granular materials, the vibration motor 10 works, and under the action of the buffer spring 62 in the buffer assembly 6, the housing 1 is driven to vibrate.
[0037] By feeding plastic granules into the housing 1 through the feed channel 2, and then screening them through the screening screen 13, the screening screen 13 vibrates under the action of the vibration of the housing 1, which accelerates the screening speed of the plastic granules. The screened plastic granules flow out from the discharge port 101 and enter the through groove 33 of the corresponding triangular guide plate 3. The material is concentrated along the triangular guide groove 32 to the arc part 31, and finally discharged from the discharge pipe 4. This avoids the material from splashing onto the ground during collection, facilitates the collection operation, enhances the collection effect, and improves the practicality of this utility model.
