Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a plastic pellet conveying device with a screening mechanism. Background Technology

[0002] Currently, screening uses a sieve to allow fine particles smaller than the sieve openings to pass through the sieve surface, while coarse particles larger than the sieve openings remain on the sieve surface, thus completing the separation of coarse and fine materials. This separation process can be seen as consisting of two stages: material stratification and fine particle screening. Material stratification is a condition for completing the separation, while fine particle screening is the purpose of the separation. Screening devices are required when screening plastic granules.

[0003] Existing plastic granules have certain problems in processing and conveying. They are often only screened once, which results in insufficient and uneven screening. Other small plastic granules often fall off during the screening, leading to poor screening effect and reducing the time and effort required for screening. To address these issues, an improved and upgraded plastic granule conveying device with a screening mechanism is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a plastic pellet conveying device with a screening mechanism to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] Design a plastic pellet conveying device with a screening mechanism, including a first screening box, a second screening box provided on the lower end face of the first screening box, a feed hopper provided on the upper end face of the first screening box, and a screening component provided inside the first screening box. The screening component includes a first motor, a stirring rod and a support plate. The first motor is fixedly mounted on the support plate and the support plate is fixedly connected to the outer wall of the first screening box. The output end of the first motor is connected to the stirring rod and a connecting shaft is fixedly provided on the outer wall of the stirring rod.

[0007] The second screening box has a feeding tray on its upper surface and a reciprocating assembly below the feeding tray. A feeding plate is located below the reciprocating assembly and a feeding assembly is located above the feeding plate. A collection box is located on one side of the second screening box. The reciprocating assembly includes a mounting frame, a second motor, and a fixing plate. The mounting frame is fixedly installed on the inner wall of the second screening box. The second motor is located inside the mounting frame and its output end is connected to the fixing plate. An eccentric wheel is fixedly installed in the middle of the fixing plate and rotates inside the guide frame. The fixing plate is rotated and installed inside the mounting frame.

[0008] Furthermore, four identical stirring racks are fixedly installed on the outer wall of the connecting shaft, and the four stirring racks are attached to the inner wall of the filter barrel, which is installed inside the first screening box.

[0009] Furthermore, guide rods are symmetrically arranged on both sides of the outer wall of the guide frame. The outer walls of the two guide rods are slidably connected to the inside of the mounting block, and the mounting block is fixedly arranged inside the mounting frame. Connectors are fixedly arranged on one side of the outer walls of the two guide rods, and the connectors are fixedly installed on the outer wall of the filter box. A filter plate is arranged inside the filter box, and a slider is arranged on the outer wall of the filter box. The slider is slidably arranged inside the mounting frame.

[0010] Furthermore, the feeding assembly includes a mounting plate, a cylinder, and a connecting block. There are two mounting plates, and each mounting plate is equipped with a cylinder. One end of each of the two cylinders is connected to a connecting block, and the connecting block is fixedly mounted on a limiting frame. Each of the two limiting frames is equipped with several limiting rollers. One end of each limiting frame is equipped with a connecting column, and both ends of the connecting column are rotatably mounted inside the limiting box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model device includes components such as a stirring rack, a filter bucket, a first motor, a fixed plate, an eccentric wheel, a guide frame, and a filter plate. By driving the first motor to rotate the connecting shaft on the stirring rod, the connecting shaft drives the four stirring racks to rotate and stir inside the filter bucket. The second motor drives the eccentric wheel on the fixed plate to rotate, which in turn drives the connecting parts on the outer walls of the two guide rods on the guide frame to move. This causes the connecting parts to move the screening box back and forth, facilitating secondary screening of plastic particles that fall onto the filter plate inside the screening box. This improves the screening and processing of plastic particles, enhances the thoroughness and uniformity of screening, and has a simple structure.

[0013] 2. The device of this utility model is equipped with components such as an installation plate, a cylinder, a limiting frame, a limiting roller, a limiting box, and a connecting column. The connecting block is driven by the driving cylinder to move the limiting frame. One end of the limiting frame rotates around the connecting column inside the limiting box as the axis. When the limiting roller is rotated to a suitable distance, it is beneficial to directly guide the plastic granules to the collection box on one side after one collection box is completed, without stopping the feeding and collection conveying. This helps to improve the feeding and conveying efficiency of plastic granules and saves time and effort.

[0022] 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.

[0023] like Figure 1 - Figure 5As shown in the figure, this embodiment provides a plastic pellet conveying device with a screening mechanism, including a first screening box 1, a second screening box 2 provided on the lower end face of the first screening box 1, and a feeding hopper 3 provided on the upper end face of the first screening box 1. The screening component 7 is provided inside the first screening box 1. The screening component 7 includes a first motor 71, a stirring rod 73 and a support plate 72. The first motor 71 is fixedly installed on the support plate 72 and the support plate 72 is fixedly connected to the outer wall of the first screening box 1. The output end of the first motor 71 is connected to the stirring rod 73 and a connecting shaft 74 is fixedly provided on the outer wall of the stirring rod 73.

[0024] The upper surface of the second screening box 2 is provided with a feeding tray 8 and a reciprocating component 9 is provided below the feeding tray 8. The feeding plate 4 is provided below the reciprocating component 9 and a feeding component 5 is provided above the feeding plate 4. A collection box 6 is provided on one side of the second screening box 2. The reciprocating component 9 includes a mounting frame 91, a second motor 92 and a fixing plate 93. The mounting frame 91 is fixedly installed on the inner wall of the second screening box 2. The second motor 92 is installed inside the mounting frame 91 and the output end of the second motor 92 is connected to the fixing plate 93. An eccentric wheel 94 is fixedly installed in the middle of the fixing plate 93 and the eccentric wheel 94 is rotatably installed inside the guide frame 95. The fixing plate 93 is rotatably installed inside the mounting frame 91.

[0025] Preferably, four identical stirring racks 75 are fixedly installed on the outer wall of the connecting shaft 74. The four stirring racks 75 are fitted and connected to the inner wall of the filter bucket 76. The filter bucket 76 is installed inside the first screening box 1. Guide rods 96 are symmetrically arranged on both sides of the outer wall of the guide frame 95. The outer walls of the two guide rods 96 are slidably connected to the inside of the mounting block 97, and the mounting block 97 is fixedly installed inside the mounting frame 91. Connectors 98 are fixedly installed on one side of the outer walls of the two guide rods 96, and the connectors 98 are fixedly installed on the outer wall of the filter box. A filter plate 991 is provided inside the filter box, and a slider 99 is provided on the outer wall of the filter box. The slider 99 is slidably installed inside the mounting frame 91.

[0026] The first motor 71 drives the connecting shaft 74 on the stirring rod 73 to rotate, causing the connecting shaft 74 to drive the four stirring frames 75 to rotate and stir inside the filter barrel 76. This stirs and turns over larger particles or small stones mixed in with the plastic granules, allowing them to be screened out. Plastic granules of suitable size fall from the feeding tray 8 into the mounting frame 91. At this time, the external power supply is turned on, driving the second motor 92 to drive the eccentric wheel 94 on the fixed plate 93 to rotate. This causes the eccentric wheel 94 to drive the connecting parts 98 on the outer wall of the two guide rods 96 on the guide frame 95 to move. As a result, the connecting parts 98 drive the screening box to move back and forth. At the same time, the guide rods 96 slide inside the mounting block 97, while the other side of the outer wall of the screening box slides in the mounting frame 91 through the slider 99, which facilitates the secondary screening of the plastic granules that fall onto the filter plate 991 inside the screening box.

[0027] Preferably, the feeding assembly 5 includes a mounting plate 51, a cylinder 52, and a connecting block 53. There are two mounting plates 51, and each mounting plate 51 is equipped with a cylinder 52. One end of each cylinder 52 is connected to a connecting block 53, and the connecting block 53 is fixedly mounted on a limiting frame 54. Each limiting frame 54 is equipped with several limiting rollers 55. One end of the limiting frame 54 is equipped with a connecting post 57, and both ends of the connecting post 57 are rotatably mounted inside the limiting box 56.

[0028] The cylinder 52 on the drive mounting plate 51 drives the upper limit frame 54 of the connecting block 53 to move. One end of the limit frame 54 rotates around the connecting column 57 inside the limit box 56. When the upper limit roller 55 of the limit frame 54 is rotated to a suitable distance, it is convenient to directly guide the plastic particles to the collection box 6 on one side after one collection box 6 has finished collecting, without stopping the feeding and collection conveying.

[0029] The working principle and process of this utility model are as follows: First, the operator puts plastic granules into the feed hopper 3, where they fall into the first screening box 1. At this time, the first motor 71 drives the connecting shaft 74 on the stirring rod 73 to rotate, causing the connecting shaft 74 to drive the four stirring frames 75 to rotate and stir inside the filter bucket 76. This stirs and turns over the larger particles or small stones mixed in with the plastic granules, and the plastic granules of suitable size fall from the feeding tray 8 into the mounting frame 91. At this time, the external power supply is turned on, driving the second motor 92 to drive the eccentric wheel 94 on the fixed plate 93 to rotate. The eccentric wheel 94 drives the connecting parts 98 on the outer wall of the two guide rods 96 on the guide frame 95 to move. Thus, the connecting parts 98 drive the screening box to move back and forth. At the same time, the guide rods 96 slide and engage inside the mounting block 97, and the screening is completed. The outer wall of the other side of the box slides in the mounting frame 91 via a slider 99, which facilitates secondary screening of the plastic particles that fall onto the filter plate 991 inside the screening box. This effectively filters out smaller particles, improving the thorough screening and filtration of the plastic particles. Unqualified plastic particles are removed from the inspection port on one side for unified processing. The screened plastic particles fall onto the feeding plate 4. At this time, when all the plastic particles in a collection box 6 have been collected, the cylinder 52 on the driving mounting plate 51 drives the upper limit frame 54 of the connecting block 53 to move. One end of the limit frame 54 rotates around the connecting column 57 inside the limit box 56. When the upper limit roller 55 of the limit frame 54 is rotated to a suitable distance, it is convenient to directly guide the plastic particles to the collection box 6 on one side after one collection box 6 has been collected, without stopping the feeding and collection conveying, saving time and effort.
