[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] This utility model provides a crushing device, the structure of which is as follows: Figure 1 - Figure 3 As shown, it includes a frame 2, a steel belt roller 1 for the film making machine, a drive gear ring 11, a rolling roller 3, and a driven gear ring 31.

[0028] The steel belt roller 1 of the film-making machine is rotatably fixed on the frame 2 for conveying materials.

[0029] The active gear ring 11 is fixed on the frame 2 and is coaxial with the steel belt roller 1 of the film making machine.

[0030] The rolling roller 3 is rotatably connected to the frame 2 and forms an inlet between it and the steel belt roller 1 of the film-making machine for material to pass through.

[0031] The driven gear ring 31 is fixed on the frame 2 and coaxial with the rolling wheel 3, and meshes with the driving gear ring 11.

[0032] In operation, the steel belt roller 1 of the tablet-making machine conveys the material. The driving gear ring 11 is coaxially fixed with the steel belt roller 1. When the steel belt roller 1 rotates, the driving gear ring 11 rotates synchronously. Since the driven gear ring 31 meshes with the driving gear ring 11, the rotation of the driving gear ring 11 drives the driven gear ring 31 to rotate through the meshing of the teeth. The driven gear ring 31 is coaxially fixed with the crushing wheel 3, which in turn drives the crushing wheel 3 to rotate. Thus, when the material is conveyed by the steel belt roller 1 and passes through the inlet between the steel belt roller 1 and the crushing wheel 3, it is crushed by the crushing wheel 3.

[0033] In this invention, a gear meshing method is adopted, and the driving gear ring 11 and the driven gear ring 31 transmit power through precise tooth profile matching, which will not cause slippage and ensures that the crushing wheel 3 rotates stably and continuously, thereby improving the crushing quality and making the crushing effect more uniform.

[0034] To reduce the possibility of damage to the driving gear ring 11 and the driven gear ring 31, please refer to... Figure 1 In a preferred embodiment, the crushing device further includes a protective cover 4, which is installed on the outside of the driving gear ring 11 and the driven gear ring 31.

[0035] During operation, the crushing device may be exposed to dust, debris, and other contaminants in its working environment. The protective cover 4 creates a relatively enclosed space, enclosing the driving gear ring 11 and the driven gear ring 31. This prevents foreign objects from getting stuck between the teeth, which could damage the gear rings or affect power transmission.

[0036] To reduce the possibility of material adhering to the compaction roller 3, please refer to... Figure 2 In a preferred embodiment, the crushing device further includes a scraper 5, which is connected to the frame 2 and abuts against the crushing wheel 3.

[0037] During operation, after the material is crushed by the crushing roller 3, some material may adhere to the surface of the roller 3. The scraper 5 is always in contact with the roller 3. When the roller 3 rotates, the scraper 5 will move relative to the surface of the roller 3. The edge of the scraper 5 is used to scrape off the material adhering to the roller 3, ensuring the consistency of crushing quality.

[0038] To further improve compaction quality, please refer to... Figure 3 In a preferred embodiment, the scraper 5 is located on the feed side of the rolling roller 3.

[0039] When in use, the scraper 5 is located on the feed side of the roller 3. When the scraper 5 scrapes off the material adhering to the roller 3, the material falls back into the feed side of the roller 3 and is crushed again by the roller 3, which further improves the crushing quality.

[0040] To ensure the material falls to the center of the steel belt roller 1 of the film-making machine, please refer to... Figure 3 In a preferred embodiment, the crushing device further includes a discharge plate, the scraper 5 gradually decreases from both ends toward the middle, the discharge plate is located in the middle of the scraper 5, and the discharge plate is provided with discharge holes 51, which face the steel belt roller 1 of the sheet forming machine.

[0041] During use, the scraper 5 gradually lowers from both ends towards the middle, allowing the material scraped from the roller 3 to naturally converge towards the center along the inclined surface of the scraper 5. Once the material reaches the middle of the scraper 5, it will fall through the discharge hole 51. The orientation of the discharge hole 51 ensures that the material falls directly onto the steel belt roller 1 of the sheet-making machine, preventing material from splashing everywhere.

[0042] To further improve the cleaning effect of scraper 5, please refer to... Figure 3 In a preferred embodiment, the crushing device further includes a spring 52. The scraper 5 is slidably connected to the frame 2 along the radial direction of the crushing wheel 3. One end of the spring 52 is connected to the scraper 5 on the side away from the crushing wheel 3, and the other end of the spring 52 is connected to the frame 2. The spring 52 is in a compressed state, and the spring 52 causes the scraper 5 to tend to slide towards the crushing wheel 3.

[0043] During use, the surface of the roller 3 may not be completely flat as it rotates. When a protrusion on the surface of the roller 3 comes into contact with the scraper 5, the protrusion exerts a reverse force on the scraper 5, causing the scraper 5 to overcome the elastic force of the spring 52 and slide radially away from the roller 3. After the protrusion has passed, the spring 52 will push the scraper 5 back towards the roller 3, restoring a close fit. The scraper 5 can adapt to the unevenness of the roller 3 surface, maintaining a good cleaning effect at all times.

[0044] To reduce the possibility of material adhering to scraper 5, please refer to... Figure 3 In a preferred embodiment, the crushing device further includes an anti-stick plate connected to the outside of the scraper 5. An anti-stick layer is connected to the side of the anti-stick plate away from the scraper 5. The anti-stick layer is made of polytetrafluoroethylene and has a thickness of 0.5 mm.

[0045] When in use, when the scraper 5 is cleaning the material on the surface of the roller 3, the material is not easy to adhere to the scraper 5, but is easier to slide off the scraper 5, thereby keeping the surface of the scraper 5 clean and ensuring that the scraper 5 can continuously and effectively clean the roller 3.

[0046] To facilitate the replacement of wheel sleeve 33 and reduce costs, please refer to... Figure 3 In a preferred embodiment, the rolling wheel 3 includes a wheel core 32, a wheel sleeve 33, and a fixing component 34. The wheel sleeve 33 is axially sleeved on the wheel core 32, and the fixing component 34 is fixedly connected to the wheel core 32. The fixing component 34 and the wheel sleeve 33 are detachably connected.

[0047] During use, the detachable connection between the fixing component 34 and the wheel sleeve 33 facilitates the replacement of the wheel sleeve 33 after wear or damage. Since the wheel sleeve 33 is in direct contact with the material, it is susceptible to wear. When the wear of the wheel sleeve 33 reaches a certain level, it needs to be replaced promptly to ensure the compaction effect. By disassembling the fixing component 34, the old wheel sleeve 33 can be easily removed from the wheel core 32, and then a new wheel sleeve 33 can be installed.

[0048] To allow the wheel sleeve 33 to be detachably connected to the wheel core 32, please refer to... Figure 3 In a preferred embodiment, the fixing component 34 includes a pressure block 341 and a lead screw 342. The lead screw 342 is rotatably connected to the end of the wheel core 32 and extends radially along the wheel core 32. The pressure block 341 is slidably connected to the end of the wheel core 32 along the radial direction of the wheel core 32. The lead screw 342 passes into the pressure block 341 and is threadedly connected to the pressure block 341 so that the pressure block 341 abuts against the end of the wheel sleeve 33.

[0049] During use, when installing the wheel sleeve 33, first fit the wheel sleeve 33 onto the wheel core 32 axially. Rotate the lead screw 342; the rotation of the lead screw 342 will cause the pressure block 341 to move radially along the wheel core 32. As the lead screw 342 continues to rotate, the pressure block 341 gradually approaches the end of the wheel sleeve 33, eventually abutting against the end of the wheel sleeve 33 and applying pressure to the wheel sleeve 33 axially along the wheel core 32. This pressure tightly fixes the wheel sleeve 33 to the wheel core 32, preventing the wheel sleeve 33 from moving axially or radially during the operation of the rolling wheel 3. When it is necessary to replace the wheel sleeve 33, rotate the lead screw 342 in the opposite direction, causing the pressure block 341 to move radially outward along the wheel core 32, gradually releasing the pressure on the wheel sleeve 33. After the pressure block 341 has completely left the end of the wheel sleeve 33, remove the wheel sleeve 33 from the wheel core 32 for replacement or repair.

[0050] To improve the stability of wheel sleeve 33, please refer to... Figure 3 In a preferred embodiment, the contact surface 35 between the wheel sleeve 33 and the pressure block 341 is inclined.

[0051] During use, when the pressure block 341 abuts against the wheel sleeve 33, the inclined contact surface 35 causes the force applied by the pressure block 341 to the wheel sleeve 33 to have both radial separation and axial components. This causes the wheel sleeve 33 to fit more tightly against the wheel core 32, further enhancing the connection stability between the wheel sleeve 33 and the wheel core 32 and preventing the wheel sleeve 33 from shifting axially during rolling.

[0052] To better understand this utility model, the following is combined with... Figure 1 - Figure 3The working principle of the crushing device of this utility model is described in detail below: The steel belt roller 1 of the flaking machine conveys material. The driving gear ring 11 is coaxially fixed with the steel belt roller 1. When the steel belt roller 1 rotates, the driving gear ring 11 rotates synchronously. Since the driven gear ring 31 meshes with the driving gear ring 11, the rotation of the driving gear ring 11 drives the driven gear ring 31 to rotate through the meshing of its teeth. The driven gear ring 31 is coaxially fixed with the crushing wheel 3, thus driving the crushing wheel 3 to rotate. In this way, when the material passes through the inlet between the steel belt roller 1 and the crushing wheel 3 under the conveying of the steel belt roller 1, it is crushed by the crushing wheel 3.

[0053] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
