Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a raw material screening device for the production of plastic products. Background Technology

[0002] Plastic products are a general term for household and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and vacuum forming. Plastics are a class of malleable synthetic polymers. Together with synthetic rubber and synthetic fibers, they form the three essential synthetic materials for daily life. Specifically, plastics are materials made primarily of natural or synthetic resins, with various additives, which can be molded into specific shapes under certain temperature and pressure conditions and maintain their shape at room temperature. Plastic raw materials are polymers, also known as macromolecules or macromolecules, and are commonly referred to as plastics or resins. Plastic raw materials are actually a type of synthetic resin, similar in appearance to natural resins like pine resin, but synthesized through chemical processes, hence the name "plastic." During the production and processing of plastic raw materials, they need to be melted to create various items. However, before melting, the raw materials need to be sieved to remove impurities and particles that do not meet particle size requirements, especially larger particles, to improve the quality of the plastic products.

[0003] Existing raw material screening devices for plastic product manufacturing have poor screening effects, affecting the screening of raw materials and their quality. Furthermore, the existing screen frames are difficult to replace after damage. The present invention provides a raw material screening device for plastic product manufacturing that solves the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a raw material screening device for plastic product manufacturing, including an outer frame 1, a rectangular frame 2, and a screen frame 3. Both sides of the rectangular frame 2 abut against a mating plate 13. The screen frame 3 is located inside the rectangular frame 2, which is located inside the outer frame 1. A servo motor 4 is mounted on the front of the outer frame 1. A disc 5 with the same center as the output axis of the servo motor 4 is mounted on the output end of the servo motor 4. A positioning slider 6 is mounted on the front of the disc 5. A connecting rod 7 is mounted on the front of the rectangular frame 2. A positioning groove is provided with the front-to-back direction as the depth direction and the up-to-down direction as the length direction. The end of the positioning slider 6 is located inside the positioning groove. The positioning slider 6 can slide along the length direction of the positioning groove. A strip plate 8 is installed on the inner front wall and inner rear wall of the outer frame 1. A strip groove with the front-to-back direction as the depth direction and the left-to-right direction as the length direction is provided inside the strip plate 8. The end of the strip slider 9 is located inside the strip groove. The strip slider 9 can slide along the length direction of the strip groove. Strip sliders 9 are installed on the front and back of the rectangular frame 2.

[0026] In use, the raw materials are placed inside the screen frame 3, and the screen frame 3 screens the raw materials. Larger materials are blocked by the mesh of the screen frame 3, making it easier to screen out larger, unqualified materials. The servo motor 4 drives the disc 5 to rotate, causing the positioning slider 6 to move in a circle around the center of the disc 5. The end of the positioning slider 6 is located inside the positioning groove. The movement of the positioning slider 6 drives the connecting rod 7 to move, and the end of the strip slider 9 is located inside the strip groove. The connecting rod 7 drives the rectangular frame 2 and the screen frame 3 to move back and forth, causing the strip slider 9 to slide along the length of the strip groove. This facilitates the back-and-forth shaking of the screen frame 3 to screen the raw materials, improving the screening effect and enhancing practicality.

[0027] Example 2

[0028] Please see Figures 1 to 3This utility model provides a technical solution: a raw material screening device for plastic product manufacturing. A fixing block 10 is installed on the top of a rectangular frame 2. The top of the fixing block 10 has a positioning groove with the vertical direction as the depth direction. The end of a positioning block 11 is inserted into the positioning groove. Positioning blocks 11 and handles 12 are installed on the front and back of a screen frame 3, respectively. Matching plates 13 are installed on both sides of the screen frame 3. Threaded holes with the horizontal direction as the depth direction are opened inside the matching plates 13 and on both sides of the rectangular frame 2. Bolts 14 are installed inside the threaded holes. A hollow block is installed on one side of the matching plate 13. 15. The cavity block 15 has a T-shaped groove with the left and right directions as the depth direction and the up and down directions as the length direction. The end of the T-shaped slider 19 is located inside the T-shaped groove. The T-shaped slider 19 can slide along the length direction of the T-shaped groove. A limit spring 16 is installed inside the cavity block 15. A limit baffle 17 is installed at one end of the limit spring 16. The side of the limit baffle 17 away from the push block 18 abuts against the end of the bolt 14. Support legs 20 are installed on both sides of the outer frame 1. A push block 18 is installed on one side of the limit baffle 17, and a T-shaped slider 19 is installed on the other side of the limit baffle 17.

[0029] When using the screen frame 3, push the push block 18 to move the limit baffle 17 and the T-shaped slider 19, moving the limit baffle 17 away from the bolt 14 and causing the T-shaped slider 19 to slide along the length of the T-shaped groove. This causes the limit spring 16 to contract under pressure. Then, loosen the bolt 14 to remove it from the threaded hole. Next, move the screen frame 3 using the handle 12 to move the positioning block 11 away from the positioning groove, separating the mating plate 13 from the rectangular frame 2, making it easy to remove the screen frame 3. Conversely, during installation, move the screen frame 3 using the handle 12. Entering the interior of the rectangular frame 2, the end of the positioning block 11 enters the interior of the positioning groove. When the bottom of the positioning block 11 abuts against the inner bottom wall of the positioning groove, the threaded hole on the mating plate 13 aligns with the threaded hole on the rectangular frame 2. Then, tighten the bolt 14 so that the bolt 14 enters the interior of the threaded hole, making the mating plate 13 and the rectangular frame 2 securely connected. Then, release the push block 18. Through the elastic tension of the limit spring 16, the limit baffle 17 abuts against the end of the bolt 14 to block the bolt 14, preventing the bolt 14 from loosening and falling off, improving the stability of the screen frame 3 installation and improving its practicality.
