[0002] A pressure roller is a mechanical device used to press, flatten or process materials into a desired shape. It is usually made of solid metal and may have protrusions or grooves on the surface to provide the required pressure and shape. Pressure rollers are widely used in metal processing, plastic processing, paper processing, printing industry and other fields for calendering, pressing, embossing, coating and other processes. Its design and material depend on the required processing task and the type of material to be processed, which can improve production efficiency and ensure product quality.

[0003] When the pressure roller is working, it is necessary to adjust the height of the pressure roller according to the size of the object to adapt to the normal production of the object. When adjusting the height, friction will inevitably occur between the two parts. If there is friction, there will be loss. At this time, it is necessary to add lubricating oil to the friction point in time to reduce friction, otherwise the height adjustment device will be damaged and eventually unusable.

[0033] Specifically, the top plate 1 and the bottom plate 19 are connected by three slide bars 30 and the threaded rod 3. The motor 2 is used to drive the threaded rod 3 to rotate. Under the limit of the slide bar 30, the threaded rod 3 rotates and moves other parts up and down together. These parts are connected to the slide 4. The pump box 5 is fixed to the left slide 4 through the fixing frame 14. The pump box 5 cooperates with the internal parts to extract the lubricating oil from the oil storage tank 11 and add it to the connection between the slide 4 and the threaded rod 3 and the slide bar 30. The spring 6 is used to push the baffle plate 7 to reset the push rod 8. The baffle plate 9 is in intermittent contact with the cam 16 to push the push rod 8 to the right. The one-way valve 10 and The one-way valve 12 is the same one-way valve, which can only transport oil upward but not downward. The oil storage tank 11 is used to store lubricating oil. The oil pipe 13 is used to transport the lubricating oil to the connection between the slide 4 and the threaded rod 3 and the slide rod 30. There is a valve above the one-way valve 12, which is opened when the lubricating oil is needed and closed when it is not needed. The motor 15 is used to drive the cam 16 and the gear 17 to rotate. The rotation of the cam 16 drives the internal parts of the pump box 5 to work normally. The gear 17 is used to drive the pressure roller 22 to rotate. The top of the fixed block 18 is fixed to the bottom of the front side clamping plate 20 to connect and support the gear 17.

[0034] Reference Figure 2, Figure 5 , Figure 6 The replacement assembly includes two clamping plates 20, the bottom left and right sides of the two clamping plates 20 are fixedly connected between the tops of the front and rear sides of the two slides 4, the left end of the clamping plate 20 is rotatably connected with a clamping plate 21, and two pressure rollers 22 are rotatably connected between the tops of the two clamping plates 20, and the front ends of the pressure rollers 22 are rotatably connected with a gear 23, the right end of the clamping plate 20 is fixedly connected with a shell 24, and a pull rod 25 is slidably connected inside the shell 24, and a baffle 26 is fixedly connected to the side of the pull rod 25 close to the pressure roller 22, and a spring 27 is fixedly connected to the side of the baffle 26 away from the pressure roller 22, and the top of the shell 24 close to the pressure roller 22 A limit plate 28 is fixedly connected to one side, and an insert plate 29 is slidably connected inside the shell 24. The bottom of the front clamp plate 20 is fixedly connected to the top of the fixed block 18, and the left gear 23 is meshed with the gear 17. The spring 27 is internally sleeved on the outside of the pull rod 25, and the end of the spring 27 away from the cam 16 is fixedly connected to the inner wall of the shell 24. The outer periphery of the baffle plate 26 is slidably connected to the inner wall of the shell 24, and the outer side of the insert plate 29 is slidably connected to the upper side of the inside of the shell 24. The outside of the pull rod 25 passes through the shell 24 and is inserted into the right side of the clamp plate 21. The bottoms of the two clamp plates 21 are rotatably connected between the front and rear ends of the two pressure rollers 22.

[0035] Specifically, the left end of the second clamp plate 21 rotates on the first clamp plate 20, and the clamp plate 20 and the second clamp plate 21 cooperate to clamp the pressure roller 22 inside to ensure that the pressure roller 22 will not move around. The pressure roller 22 is the core part of the device, and the other parts are to ensure that the pressure roller 22 can work normally. The two gears 23 are meshed to make the two pressure rollers 22 rotate synchronously in opposite directions. The left gear 23 is meshed with the gear 17, and the gear 17 is driven by the motor 215, so that the pressure roller 22 can work normally. The shell 24 is used to fix and protect The internal parts, the pull rod 25 and the second clamping plate 21 cooperate to fix the fixing roller 22. When the pull rod 25 is pulled, the second baffle 26 will compress the second spring 27. As long as the hand pull rod 25 is released, the second spring 27 will push the second baffle 26 to pop out the pull rod 25 and reset it. The limit plate 28 is used to limit the movement distance of the plug plate 29 to prevent the plug plate 29 from falling off from the shell 24. The plug plate 29 is used to block the shell 24 to prevent the pull rod 25 from resetting. When the pull rod 25 is pulled, the plug plate 29 will fall into the shell 24 to block the exit. When it needs to be fixed, just pull the plug plate 29.

[0036] Working principle: when using this device, first adjust the height of the pressure roller 22 as required, and control the rotation of motor 12 through an external power supply. Motor 12 drives the threaded rod 3 to rotate. Under the limit of the slide bar 30, all parts move up and down together. After a long time, wear will occur at the moving part of the slide 4. At this time, it is necessary to add lubricating oil in time. First, control the rotation of motor 2 15 through an external power supply. Motor 2 15 drives cam 16 to rotate. Cam 16 will intermittently push baffle 9. Baffle 9 drives push rod 8 to push baffle 1 7. Negative pressure is generated inside the pump box 5. Under the action of one-way valve 10 and oil storage tank 11, lubricating oil is sucked into the pump box 5 from the inside of the oil storage tank 11. Open the valve above the one-way valve 12, and the spring 16 will push baffle 1 7 to squeeze the lubricating oil out from the inside of the pump box 5 through the one-way valve 2 12 flows into the oil pipeline 13, and then joins the connection between the slide 4 and the threaded rod 3 and the slide rod 30 respectively to achieve lubrication. When not needed, close the valve above the one-way valve 12. Different pressure rollers 22 need to be replaced for different processes. When the pressure roller 22 is damaged, it also needs to be replaced in time. First pull the pull rod 25. When the pull rod 25 is completely pulled into the shell 24, the plug plate 29 will fall and block in front of the pull rod 25. At this time, release the pull rod 25 and it will not reset. At this time, open the clamp plate 21 upwards, remove the pressure roller 22, and put a new pressure roller 22. After putting it in place, close the clamp plate 21 again, and then pull out the plug plate 29. The spring 27 will immediately push the baffle 26 to push the pull rod 25 out and insert it into the clamp plate 21 to achieve fixation. At this time, restart the motor 15 and it can be used normally.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
