[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figures 1-6As shown, the present invention provides a paper machine wire cleaning device, including a movable box 1, on which a cleaning component 2 is provided. A top plate 3 is inclinedly provided on the top of the movable box 1. A transmission support seat 4 is provided near both ends of the top plate 3. The transmission support seat is hollow inside and has a horizontal hole that cooperates with the support guide cylinder 21. The support centers of the two transmission support seats 4 are not on the same straight line and each supports a set of cleaning components 2. The cleaning component 2 includes a support guide cylinder 21 that cooperates with the transmission support seat 4. A cleaning pipe 22 is provided inside the support guide cylinder 21 that is axially movable with it. A water inlet pipe 23 is provided at the end of the cleaning pipe 22 that is away from the support guide cylinder 21. Multiple nozzles 24 are provided on the side of the cleaning pipe 22 that are distributed along its length. Specifically, the bottom of the movable box 1 uses a sliding bolster, a bolster platform, and a screw transmission mechanism to achieve linear drive, providing the movable box 1 with the ability to move along the width direction of the mesh fabric; the top plate 3 provides a certain width interval for the two transmission support seats 4, and at the same time provides the basic conditions for axial adjustment of the spray overlap width of the two cleaning components 2; this utility model uses two sets of cleaning components 2 to spray onto the mesh fabric moving online from different directions, the relative angle and axial position of the two sets of cleaning components 2 can be dynamically adjusted, and multiple nozzles 24 simultaneously provide cleaning medium and pressure, which is beneficial to improving the cleaning efficiency of the mesh fabric.

[0026] To improve cleaning efficiency, the cleaning pipe 22 provided by this utility model has a threaded plug 25 at one end facing the inside of the support guide cylinder 21, and a core post 26 extending towards the water inlet pipe 23 is provided at the center of the threaded plug 25. The plug is detachably installed at the end of the cleaning pipe 22 to block it. By setting the core post 26 to compress the space inside the cleaning pipe 22, it helps to increase the pressure of the cleaning medium sprayed from the nozzle 24, thereby increasing the impact force of the sprayed medium on the mesh fabric and thus improving the cleaning effect.

[0027] Furthermore, the side of the core column 26 provided by this utility model is conical, and the large bottom end of the conical surface is connected to the threaded plug 25. In this way, the high-pressure water injected from the water inlet pipe 23 can be quickly distributed along the conical surface from front to back, providing an effective medium source for all nozzles 24 on the same cleaning pipe 22, thereby enabling all nozzles 24 to enter the cleaning state and form a cleaning line of a certain width on the surface of the mesh to be cleaned, which is beneficial to improving cleaning efficiency and shortening the cleaning cycle.

[0028] To facilitate motorized control of the axial relative position of the two cleaning components 2, the transmission side of the cleaning component 2 provided by this utility model is provided with a first adjustment component 5. The first adjustment component 5 includes a spring 51 disposed between the cleaning pipe 22 and the support guide cylinder 21. An adjustment rope 52 connected to a threaded plug 25 is disposed at the center of the spring 51. The adjustment rope 52 is led out from a first adjustment motor 53 disposed at the tail end of the support guide cylinder 21 and introduced through an inlet hole 54 disposed on the top plate 3. An unwinding wheel 55 for connecting to the adjustment rope 52 is disposed inside the moving box 1, and a first adjustment motor 56 for driving connection with the unwinding wheel 55 is disposed on the outside of the moving box 1. The first adjusting motor 56 drives the unwinding wheel 55 to simultaneously control the length of the two adjusting ropes 52. The real-time length of the adjusting ropes 52 in the cleaning pipe 22 and the support guide cylinder 21 can change the combined length of the cleaning pipe 22 and the support guide cylinder 21, thereby making the cleaning lines sprayed by the two cleaning components 2 on the mesh fabric have a certain overlap width. The supporting effect of the spring 51 can ensure the stability of the real-time width of the cleaning lines. In addition, the actual landing points of the two cleaning lines are different, which can enhance the cleaning intensity of the cleaning components 2 on the mesh fabric, thereby improving the cleaning efficiency of the equipment on the mesh fabric.

[0029] To prevent relative rotation between the cleaning tube 22 and the supporting guide cylinder 21, the cleaning tube 22 provided in this invention has a key-shaped protrusion 57 on its side for mounting the nozzle 24. The key-shaped protrusion 57 is movably engaged with the guide port 58 provided on the supporting guide cylinder 21. By providing the key-shaped protrusion 57 and the guide port 58, a linear pair with controllable direction can be formed. The axial engagement of the two ensures the stability of the passive conditions of the cleaning tube 22 and the supporting guide cylinder 21. The key-shaped protrusion 57 and the guide port 58 can effectively prevent relative rotation between the cleaning tube 22 and the supporting guide cylinder 21, thereby ensuring the control performance of the second adjustment component 6 on the angle of the cleaning line.

[0030] To improve the efficiency of the angle control of the motorized cleaning line, the present invention provides a second adjustment component 6 on the transmission side of the support guide cylinder 21. The second adjustment component 6 includes an assembly ring groove 61 corresponding to the transmission support seat 4 and disposed on the support guide cylinder 21. A driven gear 62 for synchronous rotation is disposed in the assembly ring groove 61. A transmission shaft 63 is disposed inside the movable box 1. A driving gear 64 is disposed at both ends of the transmission shaft 63. The driving gear 64 and the driven gear 62 are connected by belt drive. A bevel gear set 65 is disposed on the power input side of the transmission shaft 63. A second adjustment motor 66 that is connected to the bevel gear set 65 is disposed on the outside of the movable box 1. The bevel gear set 65 includes a small bevel gear that is connected to the second adjusting motor 66 for transmission. A large bevel gear that cooperates with the small bevel gear is provided on the transmission shaft 63. The small bevel gear and the large bevel gear form a set of reduction gears. The driving gear 64 and the driven gear 62 form the next level of reduction gears. The transmission shaft 63 can simultaneously drive two sets of driving gears 64 and driven gears 62, thereby providing different cleaning angles for the two cleaning components 2. This is beneficial for controlling the actual interval of the cleaning lines formed on the cleaning surface of the mesh, and using the two cleaning lines to obtain effective cleaning intensity, thereby improving the cleaning efficiency of the equipment.

[0031] To improve cleaning efficiency, the cleaning components 2 on the two transmission support seats 4 provided by this utility model are installed in opposite directions. By providing two cleaning lines sprayed onto the mesh fabric, a longer cleaning line length can be obtained by combination, thereby further increasing the unit cleaning length of the mesh fabric by this equipment and effectively shortening the cleaning cycle.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
