Specific embodiments

[0028] As Figures 1-5In a reciprocating washing device for a cylinder paper machine cage, it includes a fixed frame 3 arranged on one side of a support frame 2. A cage 1 is rotatably supported on the support frame 2. A top plate 4 is slidably arranged on the upper side of the fixed frame 3. A driving unit 5 and a cleaning plate 6 are arranged on the top plate 4. The driving unit 5 is used to drive the cleaning plate 6 to reciprocate along the axis of the cage 1. A brush 601 is arranged on one side of the cleaning plate 6, and the end of the brush 601 is attached to the surface of the cage 1.

[0029] During the use of the cage 1, a large number of fine fibers and debris will adhere to its surface. As the thickness of the adhesion increases, it will affect the working performance of the cage 1. Therefore, the process of the cage 1 directly affects the production quality of the subsequent paper, and it is necessary to remove the fibers and debris in time. In this solution, the fixed frame 3 is installed on one side of the support frame 2, and the driving unit 5 can better pull the cleaning plate 6, so as to fit on the outside of the cage 1 for stable cleaning, ensuring the cleaning effect. During use, the brush 601 maintains a certain reciprocating frequency. Due to the sufficient coverage of the brush 601, the cage 1 maintains good working performance after cleaning.

[0030] As Figure 6 In, in a preferred solution, the fixed frame 3 includes a bottom plate 301. Sleeve barrels 302 are respectively arranged on both sides of the bottom plate 301. The top plate 4 includes sliding columns 403 arranged on both sides, and the sliding columns 403 are inserted into the sleeve barrels 302.

[0031] The diameters of different cages 1 are different, and their central axes are at different heights relative to the ground. In order to ensure the cleaning effect and efficiency, the fixed frame 3 has a certain height adjustment ability to adapt to different production needs, with stable overall support and convenient adjustment.

[0032] In a preferred solution, a plurality of first through holes 303 and second through holes 404 are respectively arranged on the sleeve barrel 302 and the sliding column 403. An insertion rod 304 is inserted through the first through hole 303 and the second through hole 404, and limit pins 305 are also inserted on both sides of the insertion rod 304.

[0033] The sleeve barrel 302 and the sliding column 403 can be stably fixed through the insertion rod 304. At the same time, the limit pins 305 can prevent the insertion rod 304 from sliding out, and the overall locking effect is good.

[0034] As Figures 7-8 In, in a preferred solution, the top plate 4 includes a first cantilever plate 401 and a second cantilever plate 402. The driving unit 5 is arranged on the first cantilever plate 401. A water tank 7 is detachably arranged on the second cantilever plate 402. A water spraying assembly 8 is also arranged in the cleaning plate 6, and the water spraying assembly 8 is used to spray the side wall of the cage 1 with the water in the water tank 7.

[0035] The driving unit 5 is installed on the side far from the wire cage 1, so the overall maintenance is convenient and the operation is simple. In order to further improve the cleaning efficiency and quality, a water pump is arranged in the water tank 7, which can pump the water in the water tank 7 to wash the outer wall of the wire cage 1 through the water spraying component 8. The design is ingenious. At the same time, an electronic liquid level gauge is arranged in the water tank 7. One side of the water tank 7 is connected to the water supply pipeline, and an electronic valve is arranged on the water supply pipeline. The electronic liquid level gauge can automatically monitor the liquid level in the water tank 7, so that the electronic valve cooperates with the electronic liquid level gauge to ensure that the water volume in the water tank 7 is in a suitable state.

[0036] In the preferred solution, both sides of the first lifting plate 401 and the second lifting plate 402 are respectively fixed to the top plate 4 through rib plates 405.

[0037] By arranging the rib plates 405, the structural strength of the first lifting plate 401 and the second lifting plate 402 is ensured, the bearing capacity is guaranteed, and the overall use is more stable.

[0038] As Figures 9-11 In the preferred solution, an oval hole 406 is penetrated through the top plate 4. On the other side of the cleaning plate 6, two first mounting rods 604 are arranged in parallel. The first mounting rods 604 are inserted into the oval hole 406. The first mounting rods 604 are connected to the top plate 4 through first lock nuts 605. One side of the cleaning plate 6 is hinged to the driving unit 5.

[0039] The oval hole 406 plays a role in guiding and limiting the cleaning plate 6, ensuring that the reciprocating movement direction of the cleaning plate 6 is parallel to the rotation axis of the wire cage 1 and guaranteeing the cleaning effect. First lock nuts 605 are respectively arranged on both sides of the top plate 4. Through the first lock nuts 605, the locking state of the first mounting rods 604 and the distance between the first mounting rods 604 and the top plate 4 can be adjusted. Since the brush 601 is worn during use, the position of the first mounting rods 604 relative to the top plate 4 can be adjusted, so as to ensure that the contact part between the end of the brush 601 and the wire cage 1 is in a reasonable state.

[0040] In the preferred solution, the driving unit 5 includes a motor 501 and an output shaft 502. A turntable 503 is sleeved on the output shaft 502. One side of the turntable 503 is hinged to one side of a connecting rod 505 through a first shaft rod 504. The other side of the connecting rod 505 is hinged to the cleaning plate 6 through a second shaft rod 506. A step 603 is arranged on the cleaning plate 6, and the second shaft rod 506 is inserted into the step 603.

[0041] The motor 501 adopts a servo motor, and the overall rotation speed can be controlled by parameter adjustment to ensure relatively stable operation. The first shaft rod 504 is arranged in an eccentric manner. When the turntable 503 rotates, the connecting rod 505 can be pulled, so as to drive the cleaning plate 6. The overall locking is convenient and the use effect is good.

[0042] In a preferred embodiment, a groove 602 is provided in the middle of the cleaning plate 6, and a plurality of brushes 601 are evenly distributed outside the groove 602. The water spraying assembly 8 is located in the groove 602. The water spraying assembly 8 includes two straight plates 801 arranged in parallel. A plurality of water spraying pipes 802 are provided on the straight plates 801 along the axis. The water spraying pipes 802 are inclined to one side, and the directions of the water spraying pipes 802 on the two straight plates 801 are opposite.

[0043] The provision of the groove 802 can avoid the brushes 601 and ensure the working length of the brushes 601. At the same time, the inside of the straight plate 601 is a hollow structure, and water is supplied through the water inlet pipe 803 on one side. The plurality of water spraying pipes 802 work together, and can wash the limits and debris attached to the outer wall of the mesh cage 1 at high speed from two directions, ensuring the washing effect.

[0044] In a preferred embodiment, a third through hole 606, a fourth through hole 607 and a fifth through hole 608 are provided through the groove 602. Two second mounting rods 804 are provided outside the straight plate 801. The second mounting rods 804 are inserted into the third through hole 606. The second mounting rods 804 are connected to the cleaning plate 6 through second lock nuts 805. A water inlet pipe 803 is provided at the middle position of the straight plate 801. The two water inlet pipes 803 are respectively inserted into the fourth through hole 607 and the fifth through hole 608. The water inlet pipe 803 is connected to the water tank 7.

[0045] The installation of the straight plate 801 is convenient, and the overall installation accuracy is high, the effect is good, the installation, disassembly and maintenance are convenient, the use cost is low, and it works in combination with the brushes 601, combining dry and wet, and has stronger cleaning ability.

[0046] In a preferred embodiment, the water tank 7 includes a main water pipe 701. One end of the main water pipe 701 is connected with a pressurization chamber 702. The two sides of the pressurization chamber 702 are respectively connected to the two water inlet pipes 803 through branch water pipes 703.

[0047] The pressurization chamber 702 of the water tank 7 also plays a role in distribution, ensuring stable and efficient water supply to the water spraying assembly 8 through the two branch water pipes 703, and is convenient to use.
