Technical Field

[0001] The utility model relates to the technical field of plastic particle production and processing, in particular to a screening device for plastic particle production and processing. Background Art

[0002] Plastic particles are materials processed from plastic raw materials into small granular forms, usually composed of plastic polymers, additives, and fillers. There are generally more than 200 types of plastic particles, and when subdivided, there are thousands of them. Common plastic particles include general plastics, engineering plastics, and special plastics, etc. They can meet different needs and are widely used in various fields, such as the plastic product industry, building materials industry, and automotive industry, etc. In the production of plastic particles, a granulator is needed. The granulation process is as follows: after being extruded from the extruder at high temperature and melted to form a plastic strip, the plastic strip is cooled and then enters the granulator and is cut into plastic particles. Since during the granulation process, a part of the size of the granular finished products does not meet the use specifications, therefore, a screening machine is needed to screen the plastic particles. The screening operation is one of the more common steps in many processing steps. It usually uses a linear screen to quickly screen various plastic particles, so as to facilitate the subsequent unified processing of plastic particles of the same size and improve the processing efficiency.

[0003] During the screening process of the screening device for plastic particles, the plastic particles may accumulate in the screening device, affecting the screening efficiency. At the same time, the plastic particles may get stuck in the mesh holes of the screen, causing the screen to be blocked and reducing the screening efficiency. Summary of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-4 , a screening device for plastic particle production and processing, including a linear sieve main body 1, a bracket 101 is installed at the bottom end of the linear sieve main body 1, a discharge port 102 is opened on the linear sieve main body 1, and the plastic particles after screening inside the linear sieve main body 1 are discharged through the discharge port 102. A cover plate 2 is matched on the linear sieve main body 1, and the linear sieve main body 1 is connected to the cover plate 2 to form a screening device. A knocking groove 201 and a feeding port 3 are opened on the cover plate 2. The user puts the plastic particles to be screened into the linear sieve main body 1 through the feeding port 3 on the cover plate 2, so that the linear sieve main body 1 completes the screening and processing operation of the plastic particles.

[0023] A support column 4 is installed on the top surface of the cover plate 2. The support column 4 includes a cylinder 401 fixed on the top surface of the cover plate 2. A bearing 402 is installed on the cylinder 401, a ring 403 is installed on the outer ring of the bearing 402, and a plate body 5 is installed on the ring 403. The plate body 5 can rotate on the cylinder 401 of the cover plate 2 through the bearing 402 on the ring 403.

[0024] A cross plate 501 and two side plates 505 are fixed on the side wall of the plate body 5. A bottom plate 502 is arranged on one side of the cross plate 501. A motor 503 is installed on the top surface of the bottom plate 502. The motor 503 uses a brushless DC motor with the model JC35W5. A rotating rod 504 is installed on the output shaft of the motor 503. The rotating rod 504 extends between the two side plates 505. A knocking hammer 6 is installed on the rotating rod 504. A round rod 601 is installed on one side of the knocking hammer 6. The round rod 601 is fixed on the rotating rod 504. The installation of the motor 503 enables the knocking hammer 6 to flip between the two side plates 505 through the round rod 601 and the rotating rod 504. The knocking hammer 6 penetrates through the knocking groove 201 to knock on the screen of the linear sieve main body 1, avoiding the screen being blocked by the screened plastic particles and ensuring the normal use of the linear sieve main body 1.

[0025] Two slideways 202 are arranged on the cover plate 2. A slide plate 203 is slidably matched on the two slideways 202. The slide plate 203 is arranged on the knocking groove 201. The slide plate 203 covers and protects the knocking groove 201, avoiding plastic particles splashing outside the linear sieve main body 1 and the cover plate 2 through the knocking groove 201 when the linear sieve main body 1 is screening plastic particles. The knocking groove 201 and the feeding port 3 are respectively opened at both ends of the top surface of the cover plate 2. A block body 7 is installed on the cover plate 2. An arc-shaped groove is opened on the block body 7. The knocking hammer 6 is lapped on the block body 7. The block body 7 supports and places the knocking hammer 6.

[0026] When using a screening device to screen plastic particles, the linear screen main body 1 is supported and placed at a designated position required by the user through the bracket 101. The linear screen main body 1 is connected in cooperation with the cover plate 2. Through the feed port 3, the plastic particles to be screened are put into the interior of the linear screen main body 1. The linear screen main body 1 is started so that the linear screen main body 1 can perform the screening operation on the plastic particles. The plastic particles after screening are then discharged through the discharge port 102. After the screening is completed, the screen of the linear screen main body 1 will be blocked by plastic particles. Rotate the plate body 5 on the ring 403 of the support column 4 on the cover plate 2 so that the knocking hammer 6 supported and placed on the block body 7 can rotate in a direction. Slide the slide plate 203 on the slideway 202 so that the knocking groove 201 can be exposed. Rotate the knocking hammer 6 above the knocking groove 201. Start the motor 503 on the bottom plate 502 of the plate body 5. The rotating rod 504 of the output shaft of the motor 503 drives the round rod 601 of the knocking hammer 6 to rotate and turn between the two side plates 505. Thus, the knocking hammer 6 can knock on the screen of the linear screen main body 1, causing the plastic particles blocked on the screen to jump under force and separate from the screen holes of the screen, completing the cleaning operation of the blocked screen. When it is not necessary to knock on the screen of the linear screen main body 1, rotate the plate body 5 on the support column 4 again and place the knocking hammer 6 on the block body 7 again to complete the use.
