Description

Technical Field

[0001] This utility model relates to the field of rubber breaker roller technology, and in particular to a cooling structure for a combined rubber breaker roller. Background Technology

[0002] Rubber, with its high toughness, plays a crucial role in modern rubber industry and road paving. Before use, it needs to be thoroughly broken down. With the rapid development of science and technology, the use of rubber is becoming more and more widespread to maximize its value. Rubber breaking is inseparable from rubber breaking machines, which mainly use rollers to break down rubber. During operation, the rollers need to repeatedly contact the rubber to break it down, which can easily lead to the rollers overheating and affecting their service life. Infrequent replacement increases costs and causes great inconvenience.

[0003] Chinese Patent Publication No. CN217856443U discloses a roller temperature precision adjustment device for a breaker roller, including a roller body with a hollow interior. A cold water tank and a circulating pump are respectively located at both ends of the roller body. A spirally coiled groove is provided on the inner wall of the roller body, and a water pipe is installed within the groove, connecting the cold water tank and the circulating pump. The advantage of this invention compared to existing technologies is that it can adaptively adjust and control the roller body temperature, achieving precise temperature control. However, existing technologies have the following drawbacks: During use, the breaker roller cools by circulating cold water through the water pipe inside the spiral groove. However, after long-term use, sediment and scale accumulate in the water pipe, making pipe replacement in the spiral groove cumbersome. Excessive sediment and scale buildup can negatively impact the overall cooling effect, resulting in high maintenance costs. Therefore, a combined cooling structure for the breaker roller needs to be designed to address these issues. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling structure for a combined rubber-breaking machine roller, including a mounting cover, a connecting rod welded to one side of the mounting cover, and reinforcing ribs provided on the outer surface of the connecting rod. A limit frame is welded to the end of each reinforcing rib away from the connecting rod, and a heat-conducting support block is provided at the end of each limit frame away from the reinforcing rib. A roller body is provided outside the heat-conducting support block, and a connecting pipe is sleeved inside the limit frame.

[0023] The present invention will be further described below with reference to the embodiments. Example 1:

[0024] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting frame 7 has a rectangular cross-section. The outer wall of the connecting pipe 6 is tightly fitted to the inner wall of the limiting frame 7. The connecting cover 10 has a positioning block 14 on the side near the connecting rod 9. The connecting rod 9 has a positioning groove 15 on one side, and the positioning groove 15 is engaged with the positioning block 14. The size of the positioning block 14 is matched with the size of the positioning groove 15. The heat-conducting support block 8, the limiting frame 7, and the reinforcing rib 17 are all arranged in a cross shape on the outside of the connecting rod 9. The outside of the heat-conducting support block 8 is tightly fitted to the inner wall of the roller body 1. The connecting cover 10 has a sealing frame 12 on the side near the connecting pipe 6, and the sealing frame 12 extends into the inside of the connecting pipe 6.

Cold water is injected into the interior of the connecting pipe 6 through the water inlet pipe 20. With the help of the heat-conducting support block 8 and the reinforcing rib 17, the heat of the roller body 1 is transferred to the connecting pipe 6, thereby achieving overall cooling of the heat-conducting support block 8.
