Description

Technical Field

[0001] This utility model relates to the field of calendering machine technology, and specifically to a pressure roller cleaning system. Background Technology

[0002] After prolonged operation, dust and other debris will accumulate on the surface of the calender rollers. Therefore, timely cleaning is necessary; otherwise, the quality of the processed products will be affected.

[0003] As disclosed in the utility model publication "CN211942213U," entitled "Easy-to-Clean Pressure Roller Device," an easy-to-clean pressure roller device includes a mounting frame, a pressure roller, a fixed roller, a drive assembly, and a cleaning assembly. The cleaning assembly includes a base, a cleaning roller, a cleaning cover, and a drive motor. The base is slidably connected to the mounting frame. The cleaning cover is fixed to the top of the base. The roller shaft of the cleaning roller is fixed to the two end faces of the cleaning cover. A brush layer is fitted over the cleaning roller. The drive motor is fixed to the base and drives the cleaning roller to rotate via a second drive component. The brush layer cleans the dirt from the surface of the pressure roller or fixed roller. While this achieves a cleaning effect, the brush layer is prone to re-adhesion with dirt after cleaning, which can re-contaminate the pressure roller, resulting in a less than ideal cleaning effect. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a pressure roller cleaning system with a reasonable structural design and good cleaning effect.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A pressure roller cleaning system includes a support frame and a pressure roller mounted on the support frame. It also includes an adjusting frame, a flushing block, a tightening seat, a limiting screw, a spring, a high-pressure nozzle, a pressurized water supply device, and a high-pressure blower. The tightening seat is mounted on the support frame via the adjusting frame. The tightening seat has a sliding hole through which the limiting screw passes. The limiting screw passes through the sliding hole and is screwed into the back of the flushing block. The spring is sleeved on the limiting screw and can push the flushing block forward to fit against the pressure roller. A flushing chamber is provided on the contact surface of the flushing block and the pressure roller. The high-pressure nozzle is mounted on the tightening seat and extends into the flushing chamber. The pressurized water supply device is connected to the high-pressure nozzle. A recovery hole is provided on the bottom surface of the flushing chamber, and the suction end of the high-pressure blower is connected to the recovery hole.

[0007] In a preferred embodiment of this utility model, the adjusting frame includes a mounting base, a rotating tube, and a telescopic tube. The mounting base is fixed on the bracket and has a rotating hole adapted to the rotating tube. The rotating tube is movably disposed within the rotating hole and locked by a first locking screw. The rotating tube has a radial through hole. One end of the telescopic tube is disposed on the top clamping seat, and the other end is movably disposed within the through hole and locked by a second locking screw. The rotating tube can rotate around the mounting base to adjust the rinsing angle for better fit to the pressure roller. The telescopic tube can be adjusted to extend and retract to adjust the distance between the rinsing block and the roller surface to ensure a good fit. The position is then fixed by the first and second locking screws. The operation is simple and the adjustment is convenient.

[0008] In a preferred embodiment of this invention, the back of the rinsing block is provided with an extension hole corresponding to the position of the high-pressure nozzle, allowing it to extend into the rinsing chamber. The high-pressure nozzle passes through the extension hole, passes through the top clamping seat, and extends into the rinsing chamber, directly facing the pressure roller. The structure is reasonably and compactly designed.

[0009] In a preferred embodiment of this invention, the contact surface between the flushing block and the pressure roller is an arc-shaped surface adapted to the shape of the pressure roller. This provides good fit with the pressure roller, forming a relatively sealed flushing chamber, effectively preventing high-pressure water from splashing from the edges, reducing wastewater leakage, and improving recycling efficiency.

[0010] In a preferred embodiment of this invention, a water tank is further included, with the high-pressure blower disposed on the top surface of the water tank and its discharge end connected to the water tank. Wastewater discharged by the high-pressure blower is directly introduced into the water tank, forming an integrated circulation system.

[0011] In a preferred embodiment of this invention, the booster water supply device includes a booster pump, a booster chamber, and a pressure gauge. The pressure gauge is mounted on the booster chamber. The inlet of the booster pump is connected to the water tank, and the outlet of the booster pump is connected to the booster chamber. The booster chamber is connected to the high-pressure nozzle via a water pipe. The booster pump pumps water from the tank into the booster chamber, and the pressure gauge monitors the water pressure in the booster chamber in real time, ensuring that the flushing pressure is not affected by fluctuations in the water source, resulting in good cleaning performance.

[0012] In a preferred embodiment of this invention, the bottom surface of the water tank is inclined, and the tank wall is provided with a drain outlet at the lower position of the inclined surface. The inclined design of the bottom surface of the water tank allows sediment to slide naturally towards the drain outlet, facilitating centralized cleaning. After opening the drain outlet, the sediment can be discharged for convenient cleaning.

[0013] As a preferred embodiment of this utility model, the bottom of the water tank is equipped with a heating device to increase the water temperature and improve the cleaning effect.

[0014] As a preferred embodiment of this utility model, the bottom surface of the water tank wall is provided with corner wheels, which can move the entire cleaning system with high flexibility.

[0015] The beneficial effects of this utility model are as follows: This utility model is reasonably designed. Through the cooperation of spring and limiting screw, the flushing block is always dynamically attached to the surface of the pressure roller under the action of spring force, forming a relatively sealed flushing chamber, which effectively prevents high-pressure water from splashing from the edge and reduces sewage leakage; the high-pressure nozzle forms a high-pressure water jet in the sealed flushing chamber, which can effectively clean the dirt on the surface of the pressure roller, and the sewage generated during cleaning can be sucked away in real time by the high-pressure blower, avoiding sewage residue and secondary pollution, and the pressure roller cleaning effect is good.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] See Figures 1 to 4 This embodiment provides a pressure roller cleaning system, which includes a support 1, a pressure roller 2, an adjusting frame 3, a rinsing block 4, a tightening seat 5, a limiting screw 6, a spring 7, a high-pressure blower 8, a booster water supply device 9, a high-pressure nozzle 10, and a water tank 11. The support 1 is fixedly mounted on the frame of the calender or is directly part of the frame. The pressure roller 2 is mounted on the support 1.

[0022] The top-tightening seat 5 is mounted on the support 1 via an adjusting frame 3. Specifically, the adjusting frame 3 includes a mounting base 31, a rotating tube 32, and a telescopic tube 33. The mounting base 31 is fixedly mounted on the support 1 and has a rotating hole adapted to the rotating tube 32. The rotating tube 32 is movably disposed within the rotating hole and locked by a first locking screw 34. Specifically, the first locking screw 34 is radially screwed into the rotating hole and abuts against the outer wall of the rotating tube 32 to achieve the locking purpose. The rotating tube 32 has a radial through hole. One end of the telescopic tube 33 is fixedly mounted on the top-tightening seat 5, and the other end is movably disposed within the through hole and locked by a second locking screw 35. Specifically, the second locking screw 35 is radially screwed into the through hole and abuts against the outer wall of the telescopic tube 33 to achieve the locking purpose. When the first locking screw 34 is loosened, the rotating tube 32 can rotate around the mounting base 31 to adjust the rinsing angle for better fit with the pressure roller 2. When the second locking screw 35 is loosened, the telescopic tube 33 can be adjusted to extend and retract to adjust the distance between the rinsing block 4 and the roller surface to ensure the fit effect. Then, the first locking screw 34 and the second locking screw 45 are used to lock and fix the position. The operation is simple and the adjustment is convenient.

[0023] The top-tightening seat 5 has a sliding hole for the limiting screw 6 to pass through. The limiting screw 6 passes through the sliding hole and is screwed into the back of the flushing block 4. The spring 7 is sleeved on the limiting screw 6, with its rear end abutting against the top-tightening seat 5 and its front end abutting against the back of the flushing block 4. The elastic force of the spring 7 can push the flushing block 4 forward to fit against the pressure roller 2. Under the guidance of the limiting screw 6, the flushing block 4 can compress and spring back when subjected to force.

[0024] The flushing block 4 has a flushing cavity 41 on its mating surface where it contacts the pressure roller 2. Preferably, the mating surface of the flushing block 4 and the pressure roller 2 is an arc-shaped surface that matches the shape of the pressure roller 2. This provides good cooperation with the pressure roller 2, forming a relatively sealed flushing cavity 41, effectively preventing high-pressure water from splashing from the edges, reducing wastewater leakage, and improving recycling efficiency.

[0025] The high-pressure nozzle 10 is mounted on the top clamping seat 5 and extends into the rinsing chamber 41. Specifically, an extension hole 42 is provided on the back of the rinsing block 4 corresponding to the position of the high-pressure nozzle 10, allowing it to extend into the rinsing chamber 41. The high-pressure nozzle 10 passes through the extension hole 42, passes through the top clamping seat 5, and extends into the rinsing chamber 41, facing the pressure roller 2.

[0026] The booster water supply device 9 is connected to the high-pressure nozzle 10. The booster water supply device 9 includes a booster pump 91, a booster chamber 92, and a pressure gauge 93. The pressure gauge 93 is mounted on the booster chamber 92. The inlet of the booster pump 91 is connected to the water tank 11, and the outlet of the booster pump 91 is connected to the booster chamber 92. The booster chamber 92 is connected to the high-pressure nozzle 10 via a water pipe. The booster pump 91 pumps water from the water tank 11 into the booster chamber 92. The pressure gauge 93 monitors the water pressure in the booster chamber in real time, ensuring that the rinsing pressure is not affected by fluctuations in the water source, resulting in good cleaning performance.

[0027] The bottom surface of the flushing chamber 41 is provided with a recovery hole, and the suction end of the high-pressure blower 8 is connected to the recovery hole. The high-pressure blower 8 is located on the top surface of the water tank 11, and the discharge end of the high-pressure blower 8 is connected to the water tank. The wastewater discharged by the high-pressure blower 8 is directly introduced into the water tank, forming an integrated circulation.

[0028] Preferably, the bottom surface of the water tank 11 is an inclined surface 112 with an inclination angle of about 6 degrees, and the tank wall of the water tank 11 is provided with a discharge port 111 at the lower position of the inclined surface. The inclined design of the bottom surface of the water tank 11 allows the sediment to slide naturally to the discharge port 111, which is convenient for centralized cleaning. After opening the discharge port 111, the sediment can be discharged for easy cleaning.

[0029] Preferably, a heating device 12, such as a heating rod, is provided at the bottom of the water tank 11 to raise the water temperature in the tank, which can enhance the ability to dissolve grease and dirt and further improve the cleaning effect.

[0030] Four corner wheels 13 are provided on the bottom surface of the tank wall of the water tank 11. The corner wheels 13 provide good support for the water tank 11 and can move the cleaning system as a whole, which is highly flexible and can clean multiple calenders in turn, reducing equipment costs.

[0031] During cleaning, the position of the rinsing block 4 is adjusted by the rotating pipe 32 and telescopic pipe 33 of the adjusting frame 3 to ensure it fits well against the pressure roller 2. Then, the first and second locking screws are tightened for limiting and locking. The water pipe at the outlet of the pressurizing chamber 92 is connected to the high-pressure nozzle 10, and the water pipe at the suction end of the high-pressure blower 8 is connected to the recovery hole. The high-pressure blower 8 and the booster pump 91 are turned on. The booster pump 91 pumps water from the water tank into the pressurizing chamber 92. When the water pressure in the pressurizing chamber 92 reaches the predetermined water pressure, the valve is opened, and the high-pressure water in the pressurizing chamber 92 is transported through the water pipe and sprayed out from the high-pressure nozzle 10 onto the surface of the pressure roller 2. This effectively cleans the dirt on the surface of the pressure roller 2. The wastewater generated during cleaning is quickly sucked away by the high-pressure blower 8 through the recovery hole, avoiding wastewater residue and secondary pollution, resulting in a good cleaning effect.
