AI Technical Summary
The spray pipes of the existing molding net edge cleaning device cannot adjust the height and angle, resulting in the failure to achieve the best cleaning effect during high-speed operation, and the unreasonable nozzle setting causes the cleaning area to shift, making it impossible to effectively clean the trimming tool position.
A molded mesh edge cleaning device is designed including a spray pipe and an adjustable movable seat. The movable seat consists of the left bottom plate and the right buckle plate. The spray pipe is fixed through a semicircular hole and an elastic cushion layer, allowing the spray pipe to be flexibly adjusted in height and angle.
By adjusting the height and angle of the spray pipe, the cleaning effect is significantly improved, ensuring that the trimming knife position can be effectively cleaned, and reducing paper breakage and furnace recovery losses.

Abstract
Description
Technical Field
[0001] The utility model relates to a papermaking machine accessory, in particular to a forming net edge cleaning device. Background Art
[0002] like Figure 1 The figure shows a schematic diagram of the existing tissue paper production process. The wet section of the tissue paper machine uses felt cloth and forming wire. The pulp is sprayed out through the head box and formed and separated by the felt cloth and forming wire. Then, the paper is taken out through pressing, drying, and corrugating. Forming and separation are very important for the neatness of the edges of the base paper. The edge of the forming wire is equipped with a trimming knife. The neatness of the trimming knife on the edge of the paper directly affects whether the base paper has broken edges or broken paper. The cleanliness of the trimming knife directly affects the neatness of the base paper trimming. Therefore, the cleanliness of the trimming knife of the forming wire is particularly high.
[0003] In the prior art, the cleaning spray water pipe and nozzle at the trimming knife of the forming net form an L shape, which is directly fixed on the machine bracket, and the spray angle is perpendicular to the forming net surface. The upper and lower spray heights and spray angles of the L-shaped cleaning water pipe cannot be adjusted. When the forming net is running at high speed, the spray cleaning cannot reach the best. The front end of the spray pipe sprays water through the nozzle. When one nozzle is set, the width is too small. During production, when the forming net needs to be tensioned, the cleaning area is offset and the trimming knife position cannot be cleaned. The paper breaks and the loss time is long, the base paper joints are many, and the re-furnace loss is large. When two nozzles are set, the position arrangement is unreasonable. Utility Model Content

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.
[0021] Example 1: Figures 2 to 4 As shown, the utility model discloses a forming net trimming knife cleaning device, which is mainly composed of a movable seat 3 and a spray pipe 2. The movable seat 3 is used to install the spray pipe 2, so that the spray pipe 2 is fixed at a suitable height, angle and distance; the spray pipe 2 is used to guide water flow to clean the forming net trimming knife. The front end of the spray pipe 2 is provided with a nozzle 22 along the axial direction to spray water, and the distance between the nozzles 22 is set to 35-45mm, preferably 40mm. Within this range, the spray range of the nozzle 22 covers the forming net in a relaxed and tight state.
[0022] The movable seat 3 can be set as one piece or can be spliced by two halves. The one-piece setting is not conducive to adjusting the angle or fixing the spray pipe after the angle is adjusted. Therefore, in this solution, the movable seat 3 is formed by splicing the left bottom plate 31 and the right buckle plate 32. Mounting holes 311 and 321 are correspondingly set at both ends of the left bottom plate 31 and the right buckle plate 32. Bolts pass through the mounting holes 311 and 321 to connect the left bottom plate 31 and the right buckle plate 32 to the column 1 after splicing. Semicircular holes with semicircular cross-sections are respectively opened on the inner sides of the left bottom plate 31 and the right buckle plate 32. After the left bottom plate 31 and the right buckle plate 32 are spliced, the two semicircular holes form a complete cylindrical hole. Elastic pads 35 are provided in the semicircular holes of the left bottom plate 31 and the right buckle plate 32. The elastic pads 35 are used to fix the spray pipe 2 and prevent it from slipping. They are also used to adjust the angle and extension length of the spray pipe 2. After the elastic pads 35 are installed in the semicircular holes, the inner diameter of the cylindrical hole formed by splicing the two semicircular holes with the elastic pads 35 is smaller than the outer diameter of the spray pipe. In other words, the cylindrical hole and the body of the spray pipe 2 form an interference fit.
[0023] When adjusting, remove the movable seat and re-fix it to adjust the height. The upper and lower adjustment range is preferably about 50mm. Loosen the bolts connecting the left bottom plate 31 and the right buckle plate 32, rotate the spray pipe 2 and / or move the spray pipe 2 forward and backward, and then assemble the left bottom plate 31 and the right buckle plate 32. The spray pipe 2 is then tightly fixed at the target position. The angle between the axis of the spray pipe nozzle and the forming mesh surface is preferably 70 to 80 degrees, and the distance between the spray pipe and the forming mesh is preferably 140mm to 180mm. In order to facilitate height adjustment, the movable seat 3 can also be installed with the column 1 through other height adjustment devices, such as a slider. The movable seat 3 is fixed on the slider, the slider is slidably connected to the column, and the movable seat 3 is fixed to the slider.
[0024] Embodiment 2: Based on embodiment 1, Figure 3 As shown, this embodiment can also have the following variations: the movable seat 3 is connected to the column 1 through the base 4 .
[0025] The base 4 is in the shape of a long strip, and is provided with several rows of mounting holes 41 in the width direction to connect the base 4 and the column 1, and is provided with several groups of connecting holes 42 in the length direction to be used for mounting the left bottom plate 31 of the movable seat 3, so that the height of the movable seat 3 can be adjusted. In order to increase friction and increase the installation strength, the sides of the base 4 and the left bottom plate 31 that contact are both serrated surfaces.
[0026] During assembly, use bolts 33 to pass through the mounting holes 311 and 321 at both ends of the movable seat 3, and then insert into the connecting hole 42 of the base 4, so that the movable seat 3 is fixedly connected to the base 4. The height of the movable seat 3 can be adjusted by adjusting the bolts 33 up and down and inserting them into the connecting holes 42 at different heights. The serrated surfaces of the movable seat 33 and the base 4 engage with each other to prevent slipping.
[0027] Embodiment 3: Based on Embodiment 1 or 2, Figure 5 As shown, the present embodiment can also be deformed as follows: at least one plug plate 23 is provided at the tail end of the spray pipe body, and the plug plate 23 and the axis of the nozzle 22 form a certain angle α, α=10~20°, preferably 15°, and correspondingly, at least one strip groove 312 is provided on the inner wall of the semicircular hole of the left bottom plate 31 or the right buckle plate 32, so that when the spray pipe is installed, the plug plate 23 is inserted into the groove, and the axis of the nozzle 22 will form a certain angle with the axis of the column 1, so that the nozzle 22 and the forming net (not shown) form a certain angle.
