Description

Technical Field

[0001] This utility model belongs to the field of paper machine wire cleaning technology, specifically relating to a paper machine forming wire cleaning device for fruit bagging paper. Background Technology

[0002] In existing equipment, the cleaning process of paper machine forming wire often involves setting high-pressure spray pipes on the front of the forming wire, and spraying high-pressure water onto the forming wire to remove impurities. This method often fails to achieve the desired effect on the paper machine wire, making it difficult to completely remove the fine fibers accumulated in the gaps between the wires. The high adhesion rate of fibers and fillers on the forming wire reduces the service life of the polyester forming wire, requiring frequent replacement. In addition, the product has problems such as poor paper surface uniformity, uneven fiber distribution, large pulp clumps, and pinholes, which seriously affect the paper quality. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a paper machine forming wire cleaning device for fruit bagging paper.

[0004] The technical solution adopted in this utility model is a paper machine forming wire cleaning device for fruit bagging paper, including a high-pressure spraying mechanism and a water system. The high-pressure spraying mechanism includes a spray pipe, which is installed on the back of the paper machine forming wire and perpendicular to its moving direction. Multiple fan-shaped high-pressure nozzles are spaced apart on the spray pipe. The length direction of the high-pressure nozzles is consistent with the moving direction of the forming wire. The two ends of the spray pipe are slidably connected to the bushings. The bushings are fixed on the connecting plates. The connecting plates are installed on the frames on both sides of the paper machine. Both ends of the spray pipe extend out of the bushings and the front end is fixedly connected to the swing motor. The swing motor is fixedly installed on the frame of the paper machine and drives the spray pipe to reciprocate. The front end of the spray pipe is connected to the water system through a pressure-bearing hose.

[0005] Furthermore, the spray pipe is installed between the tension roller and the guide roller of the mesh section, and the distance between the spray pipe and the forming mesh is 10-15cm.

[0006] Furthermore, a sealing gasket is provided at the connection between the aforementioned bushing and the spray pipe.

[0007] Furthermore, a limiting plate is provided on the outside of the bushing on the spray pipe.

[0008] Furthermore, the inlet end of the aforementioned pressure-bearing hose is connected to the white water pump, and the middle part of the pressure-bearing hose is fixed to the frame by a clamp. The pressure-bearing hose portion between the clamp and the connector is in a relaxed state, and a lifting ring is slidably fitted near the connector. The top of the lifting ring is suspended from the white water chute shell by a belt.

[0009] Furthermore, the aforementioned water system includes a clear water tower and a white water tower. The clear water tower is connected to the ultra-clear filtrate tank and the white water tower, respectively. The ultra-clear filtrate tank is connected to the high-pressure spraying mechanism through a pressure-bearing hose, and the white water tower is connected to the white water tank.

[0010] Compared to existing technologies, the advantages of this invention are as follows: by setting fan-shaped high-pressure nozzles on the reverse side of the paper machine wire section, with the nozzles aligned with the forming wire, and using a oscillating motor to drive the spray pipes to oscillate back and forth, the high-flow, high-pressure spraying mode ensures full coverage of the wire surface, thoroughly removing fine fibers accumulated in the wire gaps, significantly reducing the adhesion rate between fibers and fillers, thereby extending the service life of the polyester forming wire, reducing replacement frequency, and improving overall production efficiency. Furthermore, due to the deep cleaning, it effectively solves the problems of uneven fiber distribution and large pulp clumps on the paper surface, effectively reducing the probability of pinholes appearing on the surface of the base paper.

[0012] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0013] Example 1 like Figure 1-2As shown, the paper forming wire cleaning device for fruit bagging paper includes a high-pressure spraying mechanism 1 and a water system 2. The high-pressure spraying mechanism 1 includes a spray pipe 101, which is installed on the back of the paper forming wire 4 and perpendicular to its moving direction. Multiple fan-shaped high-pressure nozzles 102 are spaced apart on the spray pipe 101. The length direction of the high-pressure nozzles 102 is consistent with the moving direction of the forming wire 4. The two ends of the spray pipe 101 are slidably connected to the bushings 103. The bushings 103 are fixed on the connecting plate 5. The connecting plate 5 is installed on the frame on both sides of the paper machine. Both ends of the spray pipe 101 extend out of the bushings 103 and the front end is fixedly connected to the swing motor 105. The swing motor 105 is fixedly installed on the frame of the paper machine and drives the spray pipe 101 to reciprocate. The front end of the spray pipe 101 is connected to the water system 2 through a pressure-bearing hose 3. Spray pipe 101 is installed between the wire tension roll 7 and the wire guide roll 8, with a distance of 10-15cm between the spray pipe 101 and the forming wire 4. Cleaning is performed immediately after the forming wire is separated from the wet paper web to prevent contaminants from transferring and accumulating on the wire guide roll, thus embedding deeper into the forming wire and becoming more difficult to remove. Fan-shaped high-pressure nozzles are installed on the reverse side of the paper machine's wire section, with the nozzles aligned with the forming wire. A swing motor drives the spray pipe to swing back and forth. The high-flow, high-pressure spray pattern ensures full coverage of the wire surface, thoroughly removing fine fibers accumulated in the wire gaps, significantly reducing the adhesion rate of fibers and fillers, thereby extending the service life of the polyester forming wire, reducing replacement frequency, and improving overall production efficiency. Furthermore, due to the deep cleaning, the problem of uneven fiber distribution and large pulp clumps on the paper surface is effectively solved, significantly reducing the probability of pinholes appearing on the surface of the base paper.

[0014] To ensure the sealing of the connection between the bushing 103 and the spray pipe 101 and to improve the working environment of the bushing, a sealing gasket 107 is provided at the connection between the bushing and the spray pipe.

[0015] A limiting plate 104 is provided on the spray pipe 101 outside the bushing 103, which has a limiting effect on the reciprocating motion of the spray pipe 101 and prevents it from moving and slipping.

[0016] The inlet end of the pressure hose 3 is connected to the white water pump, and the middle part of the pressure hose 3 is fixed to the frame by the clamp 301. The part of the pressure hose 3 between the clamp 301 and the connector 106 is in a loose state, and a lifting ring 302 is slidably sleeved near the connector 106. The top of the lifting ring 302 is suspended on the white water chute shell by the belt 303.

[0017] The water system 2 includes a clear water tower 201 and a white water tower 202. The clear water tower 201 is connected to the ultra-clear filtrate tank 203 and the white water tower 202 respectively. The ultra-clear filtrate tank 203 is connected to the high-pressure spraying mechanism 1 through a pressure-bearing hose 3. The white water tower 202 is connected to the white water tank 6. The traditional water is switched to recycled ultra-clear white water that has been treated by multiple plates. Through high-efficiency filtration, fine fibers in the water are removed to ensure that the recycled water quality meets the high-pressure spraying standard, thereby realizing the recycling of water resources, reducing dependence on fresh water resources, and effectively controlling production costs.
