Description

Technical Field

[0001] This invention belongs to the field of crushing technology, and specifically relates to a polytetrafluoroethylene crushing device with a cooling function. Background Technology

[0002] Polytetrafluoroethylene (PTFE) is a polymer compound formed by the polymerization of tetrafluoroethylene. It has excellent chemical stability, corrosion resistance, sealing properties, high lubricity and non-stickiness, electrical insulation, good anti-aging resistance, and excellent temperature resistance.

[0003] A search revealed Chinese patent application number 202420872670.1, which discloses a waste plastic crusher. By configuring a water tank, support plate, first water pipe, and liquid supply assembly, the liquid supply assembly draws coolant from the water tank on one side of the machine casing and delivers it to the two crushing rollers through the first water pipe. As the coolant passes through the crushing rollers and flows out through the first water pipe at the other end, it cools the crushing rollers. Finally, through the connecting pipe, a circulating water cooling effect is achieved, solving the problem of continuously rising crushing roller temperature in existing technologies. The phenomenon of plastic adhesion occurs. During the cooling process of the above-mentioned device, the coolant in the water tank is transported to the inside of the two crushing rollers through the first water pipe. After flowing through the crushing rollers, it is discharged through the second water pipe at the other end. However, the cooling system has the problem of untimely heat dissipation during operation. The coolant absorbs a lot of heat when flowing through the first water pipe and the crushing rollers. If it is not discharged in time, some of the coolant may vaporize due to heat absorption. The vaporized coolant not only cannot effectively carry away the heat, but will also remain in the system and continue to heat the unvaporized liquid, thereby reducing the overall cooling efficiency and weakening the cooling effect of the device on the crushing rollers. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a polytetrafluoroethylene crushing device with a cooling function. The coating component is used to coat the crushing component with coolant, which increases the contact area between the coolant and the crushing component.

A heat-conducting guide plate 406 is also provided on the inner wall of the crushing box 401. The heat-conducting guide plate 406 is connected to the crushing box 401. The crushing component 4 is used to crush polytetrafluoroethylene. The cooperation between the first crushing roller 402 and the second crushing roller 405 can crush polytetrafluoroethylene. The arrangement of the first gear 408 and the second gear 407 can ensure that the first crushing roller 402 and the second crushing roller 405 rotate simultaneously, thereby improving the crushing quality of polytetrafluoroethylene.

[0046] The heat-conducting guide plate 406 can guide the polytetrafluoroethylene (PTFE) to be crushed and transport it between the first crushing roller 402 and the second crushing roller 405.

The connecting rod 601 is designed to work with the rotating arm 702 to pull the lifting rod 606 up and down, thereby achieving the purpose of reciprocating downward pressure on the polytetrafluoroethylene.

[0051] When the rotating arm 702 rotates, it will cause the slider 604 at the end of the rotating arm 702 to move in the guide groove 602 on the connecting rod 601. When the slider 604 moves to the end of the guide groove 602, it will pull one end of the connecting rod 601 to move. The movement of one end of the connecting rod 601 will pull the lifting rod 606 to move downward along the strip hole 501 on the feed hopper 5, thereby driving the lower pressure plate 607 to move downward. The downward movement of the lower pressure plate 607 will achieve the purpose of pressing down the polytetrafluoroethylene.

[0052] In this embodiment, as Figure 8 As shown, a guide groove 602 is formed on the connecting rod 601. A first guide rod 603, a second spring 605, and a slider 604 are arranged in the guide groove 602.

The second spring 605 is sleeved on the first guide rod 603. The first guide rod 603 is used to guide the slider 604 and also to limit the slider 604, preventing the slider 604 from falling out of the guide groove 602 and ensuring the normal operation of the device.

[0053] The second spring 605 provides power for the lower pressure plate 607 to reset, ensuring that the lower pressure plate 607 can reciprocate up and down under the action of the rotating arm 702, thereby squeezing polytetrafluoroethylene into the first crushing roller 402 and the second crushing roller 405, thus improving the crushing quality of polytetrafluoroethylene.

[0054] In this embodiment, as Figure 10As shown, a material feeding device 2 is provided in the feeding box 1. The material feeding device 2 can move the crushed polytetrafluoroethylene to prevent the polytetrafluoroethylene from sticking together due to high temperature.

[0055] In this embodiment, as Figure 10 As shown, the feeding component 2 includes a feeding plate 201, a mounting shaft 202, a rocker arm 203, and a mounting rod 204. The feeding plate 201 is rotatably mounted on the feeding box 1 via the mounting shaft 202. The end of the rocker arm 203 is fixedly mounted on the mounting shaft 202. A waist-shaped hole 208 is opened on the rocker arm 203. A fixing hole 205 is opened in the middle of the mounting rod 204. A sliding block 209, a third spring 206, and a second guide rod 2010 are arranged in the fixing hole 205. The second guide rod 2010... The two ends of 010 are respectively fixedly installed on the two inner walls of the fixing hole 205. The sliding block 209 is slidably installed on the second guide rod 2010. The third spring 206 is sleeved on the second guide rod 2010. A sliding column 207 is provided on the sliding block 209. The sliding column 207 is set in the waist-shaped hole 208. The feeding component 2 can move the crushed polytetrafluoroethylene to prevent the polytetrafluoroethylene from sticking together due to high temperature, thus ensuring the crushing efficiency and crushing quality of polytetrafluoroethylene.

[0056] The waist-shaped hole 208 facilitates the sliding column 207 to drive the rocker arm 203 to swing, ensuring the normal operation of the device.

[0057] When the crushed PTFE falls onto the feeding box 1, it lands on the feeding plate 201. Due to the inclined setting of the feeding plate 201, it rotates. This rotation drives the mounting shaft 202 to rotate, which in turn drives the rocker arm 203 to rotate. The rocker arm 203 then moves the sliding column 207, causing the sliding block 209 to move along the fixing hole 205. During this movement, the sliding block 209 compresses or stretches the third spring 206. When the PTFE falls to the bottom of the feeding box 1, the third spring 206 resets, which in turn resets the sliding block 209. This reset of the sliding block 209 then resets the sliding column 207, which in turn resets the rocker arm 203, thus resetting the feeding plate 201. The oscillation of the feeding plate 201 in this way disperses the PTFE.

[0058] In this embodiment, as Figure 1 As shown, support legs 8 are provided at the four corners of the support plate 409. The support legs 8 are used to support the device and ensure that the device is always in a stable state during operation.

[0059] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
