[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: Reference Figure 1-4The illustrated raw material crushing device for foam board processing includes an outer frame 1, which supports and protects the internal components, providing a stable structural foundation for the entire crushing device. A pair of rotating rollers 14 are rotatably connected to the inner wall of the outer frame 1. The rotating rollers 14 are used to squeeze and initially crush the raw materials, breaking larger pieces of raw materials into smaller particles through mutual rotation. A first rotating shaft 5 is fixedly connected to one end of the rotating roller 14, and a second rotating shaft 15 is fixedly connected to the other end. Both the first rotating shaft 5 and the second rotating shaft 15 pass through the outer frame 1. These two rotating shafts can connect the rotating roller 14 to an external power source to drive the rotating roller 14 to rotate, while ensuring the stability of the rotating roller 14 during rotation. Heat dissipation holes are opened on the inner side of the rotating roller 14 to assist in heat dissipation and prevent the rotating roller 14 from overheating due to friction during long-term operation, which would affect the crushing effect and the life of the equipment. A circulating cooling pipe 17 is fixedly connected to the inner wall of the heat dissipation hole. Coolant flows through the circulating cooling pipe 17 to further enhance the heat dissipation effect. The two ends of the circulating cooling pipe 17 are respectively connected to a first rotating shaft 5 and a second rotating shaft 15 to realize the circulation path of the coolant. A pair of cooling components are arranged on the outer side of the outer frame 1. The cooling components include a circulating cooling pump 6 located on the outer side of the outer frame 1. The circulating cooling pump 6 is used to provide power to make the coolant circulate in the circulating cooling pipe 17. The output end of the circulating cooling pump 6 is fixedly connected to an output pipe 8. The output pipe 8 delivers the coolant output by the circulating cooling pump 6 to one end of the circulating cooling pipe 17 to ensure that the coolant can smoothly enter the circulating cooling pipe 17. The output pipe 8 is connected to one end of the circulating cooling pipe 17 to realize the effective delivery of coolant. The input end of the circulating cooling pump 6 is fixedly connected to a return pipe 7. The return pipe 7 is used to return the coolant that has completed the heat dissipation task in the circulating cooling pipe 17 to the circulating cooling pump 6, forming a circulation loop for the coolant.

[0023] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that gears 4 are fixedly connected to the outer sides of a pair of first rotating shafts 5, and the pair of gears 4 mesh with each other. Through this meshing method, the two gears 4 can transmit power to each other. When one gear 4 rotates, it can drive the other gear 4 meshing with it to rotate synchronously in the opposite direction, thereby providing a power transmission basis for the rotation of related components. A mounting bracket 10 is fixedly connected to the outer side of the outer frame 1, and a motor 11 is fixedly connected to the inner wall of the mounting bracket 10. A transmission gear 12 meshing with the gear 4 is fixedly connected to the output end of the motor 11. The motor 11 serves as a power source and generates power after starting. The rotational power generated is transmitted to the transmission gear 12 through the output end. The transmission gear 12 meshes with the gear 4, thereby transmitting the power to the gear 4, which in turn drives the first rotating shaft 5 and other components connected to the gear 4 to rotate, realizing the power drive of the device. A pair of fixed frames 9 are fixedly connected to the outer side of the outer frame 1. The circulating cooling pump 6 is fixedly connected to the fixed frames 9. The circulating cooling pump 6 can continuously circulate and transport the cooling medium to cool the parts that generate heat during the operation of the device. A bottom frame 2 is fixedly connected to the bottom of the outer frame 1, and a connected conveying pipe 3 is fixedly connected to the top of the outer frame 1. A pair of inclined plates 13 are fixedly connected to the inner side of the outer frame 1. The bottom frame 2 plays the role of supporting and stabilizing the outer frame 1, ensuring that the entire device is placed stably. The conveying pipe 3 is used to transport the material to be processed into the device. The inclined plates 13 can guide the flow direction of the material in the device, making it more evenly distributed and moving, which is beneficial to the subsequent processing steps. A crushing cylinder 16 is fixedly connected to the outer side of the rotating roller 14. The rotating roller 14 is made of copper. The rotating roller 14 drives the crushing cylinder 16 to rotate, and the rotation of the crushing cylinder 16 is used to crush the material, thereby realizing the crushing process of the material. The rotating roller 14, made of copper, has good electrical and thermal conductivity, which can help dissipate heat to a certain extent. At the same time, its relatively good toughness and strength can ensure the stability and durability of the rotating roller 14 during long-term use.

[0024] The working principle of this utility model is as follows: Raw materials are introduced into the outer frame 1 through the feed pipe 3. The raw materials are guided between a pair of rotating rollers 14 by a pair of inclined plates 13. The motor 11 drives the transmission gear 12 to rotate. Through the setting of a pair of gears 4, the pair of rotating rollers 14 and the crushing cylinder 16 are driven to rotate to crush the raw materials. During the crushing process, the crushing cylinder 16 introduces heat into the copper rotating rollers 14. The circulating cooling pump 6 is controlled to introduce condensate into the circulating cooling pipe 17 through the output pipe 8 to dissipate heat from the rotating rollers 14. The condensate that has absorbed heat flows back to the circulating cooling pump 6 through the return pipe 7. The crushed raw materials are discharged through the bottom frame 2.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
