Description

Technical Field

[0001] This utility model relates to the technical field of pelletizers for EPDM pellet processing, specifically a pelletizer for EPDM pellet processing. Background Technology

[0002] This pelletizer for EPDM granulation has been widely used in the field of chemical equipment technology. It is mainly used to cut plastic strips after raw materials are extruded into pellets. It has a screening function, effectively solving problems such as inconsistent pellet size and breakage after cutting, thereby improving the quality of EPDM pellets and influencing the processing of subsequent products.

[0003] According to the patent application published on the Internet, a pelletizer for EPDM particle processing (authorization announcement number: CN215996899 U) is described as follows: "This utility model relates to the field of particle processing technology, specifically an EPDM particle processing device, including a processing box. The processing box is equipped with: a crushing component, including a rotating part and several crushing blades mounted on the rotating part; a screening component, located at the lower part of the crushing component, including an arc-shaped screening element, which is elastically mounted on a lifting platform. The lifting platform drives the arc-shaped screening element to rise and fall intermittently. When the lifting platform moves to its maximum stroke, the crushing component crushes the EPDM particles in the arc-shaped screening element; a vibration component, used to drive the arc-shaped screening element to vibrate when the lifting platform moves to its minimum stroke; and a conveying component, located at the lower part of the screening component. This utility model, by designing a lifting platform, enables the crushing component to supplement the crushing of EPDM particles that do not meet the requirements after screening by the arc-shaped screening plate, avoiding the current problem that some crushed EPDM particles cannot meet the particle size requirements."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This utility model can crush EPDM granules by setting up a crushing component during use. However, the crushing process is too monotonous and the size of the crushed EPDM granules cannot be adjusted. The crushed granules are transported out of the box by setting up a conveyor belt and a guide trough. However, in actual use, the device cannot separate some waste materials from the finished products, which is inconvenient for subsequent use. Therefore, it is necessary to modify the pelletizer for EPDM granule processing to solve the above problems. Utility Model Content

This allows the device to adjust the movement of the second crushing rod 36 more stably, enabling the production of pellets of different sizes.

[0032] The first threaded rod 310 is rotatably connected to the first slider 35, and the first threaded rod 310 is threadedly connected to the second slider 38, making the movement of the second pulverizing rod 36 more stable.

[0033] Example 2:

[0034] Based on Example 1, please refer to Figure 4-6When the device is working, the waste cannot be processed to avoid mixing with the finished product. Therefore, the device is also equipped with a transport mechanism 5. The transport mechanism 5 includes a transport motor 51, which is fixedly connected to the left side of the cleaning box 4.

[0035] In order to separate EPDM particles of different sizes, the device is also equipped with a sliding assembly including a limiting plate 611. The limiting plate 611 is fixedly connected inside the housing 1. A sliding frame 612 is slidably connected inside the limiting plate 611. A screen 613 is fixedly connected inside the sliding frame. A transport trough 614 is fixedly connected to the right side of the limiting plate 611, which facilitates the grading of the particles crushed by the device and makes it easy to use.

[0036] There are two sieves 613, which are arranged in parallel inside the box 1. The sieves 613 are set as inclined plates to facilitate the grading and screening of the EPDM particles crushed by the device.

[0037] To make the sliding plate move more stably, a vibration motor box 621 is fixedly connected to the bottom surface of the limiting plate 611. A vibration motor 622 is inside the vibration motor box 621. A vibration motor 622 is fixedly connected to the output end of the vibration motor 622. A rotating shaft 623 is fixedly connected to the output end of the vibration motor 622. An elliptical block 624 is fixedly connected to the surface of the rotating shaft 623. A fixing plate 626 is slidably connected inside the limiting plate 611. A spring 625 is fixedly connected between the fixing plate 626 and the sliding frame 612, so that the screen 613 can move back and forth, making screening more convenient.

[0038] There are two elliptical blocks 624, and both elliptical blocks 624 are fixedly connected to the surface of the rotating shaft 623. The surfaces of the two elliptical blocks 624 are in contact with the two sliding frames 612, making the movement of the screen 613 more stable.

[0039] In actual operation, when this device is used, EPDM granules are first placed into the housing 1 through the feed inlet 2. The threaded motor 39 is turned on, which drives the first threaded rod 310 to rotate. The first threaded rod 310 drives the second slider 38 to move, which in turn drives the second crushing rod 36 to move. After reaching the designated position, the crushing motor 32 is turned on, which drives the first crushing rod 33 to rotate. The first crushing rod 33 drives the first gear 34 to rotate, which in turn drives the second gear 37 to rotate the second crushing rod 36 to process the EPDM granules. The vibration motor 622 is then turned on, which drives the vibration motor 622 to process the EPDM granules. 22. The rotating shaft 623 is driven to rotate, which in turn drives the elliptical block 624 to rotate. With the help of the spring 625, the sliding frame 612 is moved to screen the crushed EPDM particles. With the help of the conveyor trough 614, the screened EPDM particles are transported to the outside of the box 1. The conveyor motor 51 is turned on, which drives the first rotating rod 52 to rotate. With the help of the conveyor belt 54, the second rotating rod 53 is rotated. The last EPDM particles inside the box 1 are transported to the outside of the box 1 through the discharge port 9. The waste material after crushing the EPDM particles falls into the cleaning box 4 through the cleaning port 8. The waste material is transported to the outside of the box 1 through the conveyor belt 54.
