Description

Technical Field

[0001] This utility model relates to the field of rubber production technology, specifically to a grinding device for EPDM rubber raw materials. Background Technology

[0002] During the production of EPDM rubber, the raw materials need to be ground using grinding equipment. Since EPDM rubber raw materials are usually in block or granular form, grinding can process them into finer powders or particles, increasing the specific surface area. This allows them to be better mixed with other additives such as vulcanizing agents and fillers during subsequent mixing, molding, and other processing, improving the convenience of processing and the quality stability of rubber products.

[0003] In practical applications, some raw materials are prepared using recycled rubber. After the recycled rubber is initially crushed by a crushing device, it forms granular raw materials. Since the recycled rubber may contain a certain amount of metal waste, the granular raw materials may also contain a small amount of metal scrap. During subsequent grinding, the metal scrap may aggravate the wear of the grinding rollers, and the mixing of metal scrap into the raw materials will also affect the purity of the raw materials, thereby affecting the product quality. Therefore, a grinding device for EPDM rubber raw materials is proposed to solve the above-mentioned problems. Utility Model Content

[0027] Example 1

[0028] Please see Figures 1-5 As shown, a grinding device for EPDM rubber raw materials includes a housing 1. Two grinding rollers 5 are rotatably mounted on the inner wall of the housing 1. The front and rear ends of the grinding rollers 5 pass through the front and rear sides of the housing 1, respectively. The rear ends of the two grinding rollers 5 are respectively connected to gears 7, which mesh. A motor 6 is mounted on the front side of the housing 1 via a bracket. The front end of the left grinding roller 5 is connected to the output end of the motor 6. The motor 6 drives the left grinding roller 5 to rotate clockwise. The left grinding roller 5 drives the right grinding roller 5 to rotate through the meshing of the two gears 7. The two grinding rollers 5 rotate in opposite directions.

[0029] In addition, the separation assembly includes a magnetic roller 8, which is installed inside the housing 1. The front and rear ends of the magnetic roller 8 pass through the front and rear sides of the housing 1, respectively. A belt 9 is connected between the front end of the magnetic roller 8 and the right-side grinding roller 5 via a pulley. The magnetic roller 8 is located above the two grinding rollers 5. The magnetic roller 8's front and rear ends pass through the front and rear sides of the housing 1, respectively. A belt 9 is connected between the front end of the magnetic roller 8 and the right-side grinding roller 5 via a pulley. The right-side grinding roller 5 drives the magnetic roller 8 to rotate via the belt 9. The magnetic roller 8 is located above the two grinding rollers 5. The surface of the magnetic roller 8 has a certain magnetic force. When the raw material contains metal shavings, the magnetic roller 8 attracts the metal shavings to its surface. The inner wall of the housing 1 is equipped with two upper guide plates 2, two middle guide plates 3, and a bottom guide plate 4. The two upper guide plates 2 are located above the magnetic roller 8, forming a hopper. After being guided by the two upper guide plates 2, the raw material falls onto the surface of the magnetic roller 8. The two middle guide plates 3 are located above the two grinding rollers 5, respectively. The two middle guide plates 3 guide the raw material, ensuring that it falls between the two grinding rollers 5. The bottom guide plate 4... Below the two grinding rollers 5, the ground material slides out of the housing 1 through the bottom guide plate 4; a long groove is provided on the right middle guide plate 3, and a scraper 11 is slidably connected in the long groove of the right middle guide plate 3. The scraper 11 contacts the outer wall of the magnetic roller 8. A collection box 10 is connected through the right side of the housing 1, and a drawer is provided inside the collection box 10. The drawer of the collection box 10 is located below the scraper 11; when the metal shavings adsorbed on the surface of the magnetic roller 8 move to the scraper 11, the scraper 11 scrapes off the metal shavings, and the metal shavings slide down the long groove of the right middle guide plate 3. The trough falls into the drawer of the collection box 10, and the drawer is designed for easy cleaning by staff. The rear end of the magnetic roller 8 is connected to a slanted wheel 14, and the rear end of the scraper 11 is connected to a sliding rod 12. The sliding rod 12 is slidably connected to the housing 1. The end of the sliding rod 12 away from the scraper 11 is connected to a concave block 13. When the slanted wheel 14 rotates, it contacts the concave block 13. When the slanted wheel 14 rotates, it drives the concave block 13 to move back and forth. The concave block 13 drives the scraper 11 to move back and forth through the sliding rod 12. The scraper 11 can optimize the scraping effect of metal chips by moving back and forth.

[0030] In this embodiment, the arrangement of the magnetic roller 8, scraper 11, and collection box 10 enables the magnetic roller 8 to adsorb metal shavings contained in the raw material onto its surface before grinding. Then, the scraper 11 and the magnetic roller 8 work together to scrape the metal shavings into the collection box 10 for collection, thus achieving the effect of separating metal shavings from the raw material and improving the purity of the raw material. The cooperation of the inclined wheel 14 and the concave block 13 enables the scraper 11 to continuously reciprocate, thereby optimizing the effect of scraping off metal shavings.

[0031] Example 2

[0032] Please see Figures 4-7 As shown, the anti-blocking component includes a light rod 15, which is connected to the housing 1. Multiple paddles 16 are linearly arrayed on the light rod 15, located between two upper guide plates 2. A connecting rod 17 connects the concave block 13 to the light rod 15. When the concave block 13 moves back and forth, it drives the light rod 15 to move back and forth via the connecting rod 17. The light rod 15 drives the multiple paddles 16 to move synchronously. The multiple paddles 16, through their back-and-forth movement, can evenly move the material between the two upper guide plates 2. Two mounting plates 20 are connected between the inner walls of the front and rear sides of the housing 1. The two mounting plates 20 are located below the two upper guide plates 2, respectively. A slider 21 is slidably connected through the mounting plate 20. A hammer 22 is connected to the top of the slider 21. The bottom of the slider 21 is arc-shaped. Two bent tubes 18 are connected to the outer wall of the connecting rod 17. An arc-shaped block 19 is connected to the end of the bent tube 18 away from the connecting rod 17. When the two arc-shaped blocks 19 move, they slide in contact with the bottom of the two sliders 21 respectively. When the two hammers 22 move, they contact the bottom surface of the two upper guide plates 2 respectively. Each time the arc-shaped block 19 makes a back-and-forth reciprocating motion, it can drive the slider 21 to slide upward on the mounting plate 20 through the arc-shaped contact. When the slider 21 moves upward, it drives the hammer 22 to move upward, so that the hammer 22 strikes the bottom of the upper guide plate 2.

[0033] In this embodiment, the arrangement of the light rod 15 and multiple paddles 16 allows the multiple paddles 16 to move back and forth to evenly move the material between the two upper guide plates 2, while promoting the material to fall and avoiding blockage. The arrangement of two hammers 22 allows the two hammers 22 to strike the bottom of the two upper guide plates 2 respectively, causing the upper guide plates 2 to vibrate, thereby promoting the downward movement of the raw material and further optimizing the process of the raw material falling.

[0034] In use, the grinding equipment for EPDM rubber raw materials of this utility model allows the raw material to enter the housing 1 through the top of the housing 1. Two upper guide plates 2 form a hopper. After being guided by the two upper guide plates 2, the raw material falls onto the surface of the magnetic roller 8. The surface of the magnetic roller 8 has a certain magnetic force. When the raw material contains metal shavings, the magnetic roller 8 attracts the metal shavings to its surface. The motor 6 drives the left grinding roller 5 to rotate clockwise. The left grinding roller 5 drives the right grinding roller 5 to rotate through the meshing of two gears 7. The two grinding rollers 5 rotate in opposite directions. The right grinding roller 5 drives the magnetic roller 8 to rotate through the belt 9. Both the magnetic roller 8 and the right grinding roller 5 rotate counterclockwise. During the rotation of the magnetic roller 8, the raw material that is not attracted to the surface falls between the two grinding rollers 5. The two middle guide plates 3 guide the raw material to ensure that it falls between the two grinding rollers 5. The two grinding rollers 5 grind the raw material. The ground raw material slides out of the housing 1 through the bottom guide plate 4. The raw material attracted to the surface of the magnetic roller 8... When the metal shavings move with the magnetic roller 8 to the scraper 11, the scraper 11 scrapes them off. The metal shavings then fall down the long groove of the right middle guide plate 3 into the drawer of the collection box 10. The drawer is designed for easy cleaning by staff. Simultaneously with the rotation of the magnetic roller 8, the magnetic roller 8 drives the inclined wheel 14 to rotate. The rotation of the inclined wheel 14 causes the concave block 13 to move back and forth. The concave block 13, through the slide rod 12, drives the scraper 11 to move back and forth. The back-and-forth movement of the scraper 11 optimizes the scraping of metal shavings. The effect of removing metal shavings is achieved through the arrangement of the magnetic roller 8, scraper 11, and collection box 10. The magnetic roller 8 can adsorb the metal shavings contained in the raw material onto its surface before grinding. Then, the scraper 11 and the magnetic roller 8 work together to scrape the metal shavings into the collection box 10 for collection, thus achieving the effect of separating metal shavings from the raw material and improving the purity of the raw material. The cooperation of the inclined wheel 14 and the concave block 13 enables the scraper 11 to continuously reciprocate back and forth, thereby optimizing the effect of scraping off metal shavings.

[0035] When the concave block 13 moves back and forth, it drives the guide rod 15 to move back and forth via the connecting rod 17. The guide rod 15 drives multiple paddles 16 to move synchronously. The multiple paddles 16 can evenly move the material between the two upper guide plates 2 through the back and forth movement. When the connecting rod 17 moves back and forth, it drives the two curved blocks 19 to move back and forth via the two bent tubes 18. Each time the curved block 19 makes a back and forth movement, it can drive the slider 21 to slide upward on the mounting plate 20 through the curved surface contact. When the slider 21 moves upward, it drives the hammer 22 to move upward, so that... Hammer 22 strikes the bottom of the upper guide plate 2. When the arc block 19 is not in contact with the slider 21, the slider 21 and hammer 22 are reset by gravity. The setting of the light rod 15 and multiple paddles 16 allows the multiple paddles 16 to move back and forth to evenly move the material between the two upper guide plates 2, while promoting the material to fall and avoiding blockage. The setting of the two hammers 22 allows the two hammers 22 to strike the bottom of the two upper guide plates 2 respectively, causing the upper guide plates 2 to vibrate, thereby promoting the material to slide down and further optimizing the material falling process.

[0036] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
