Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, specifically to a positioning device for a paper-collecting screen. Background Technology

[0002] In the process of making Xuan paper, one or two paper-making technicians hold a screen and swing it back and forth in the pulp tank to make paper. Then, the paper-making screen is lifted out of the paper-making tank. After the water is drained, the paper-making screen is separated from the paper-making screen and the pulp side is pressed against the stacked paper support. Then the paper-making screen is lifted and separated from the pulp layer. This process is repeated until layers of wet paper are finally obtained.

[0003] To ensure the edges of stacked wet paper are aligned, a positioning mechanism is typically installed on the paper-laying support. For example, the technical solution disclosed in the applicant's submission dated July 26, 2023, entitled "Positioning Device for Paper-Retrieving Curtain (Document No. CN220579679U)," includes a first positioning rod (also called a support) and a second positioning rod (also called a reducer) on the paper-laying support. In the prior art, the paper-laying support is made of wood, while the support and reducer are made of bamboo, making them prone to wear. Although the solution provided in the aforementioned document solves the positioning problem of the paper-retrieval curtain, the current method for installing the support and reducer is to nail them into the mounting holes on the paper-laying support. Since the support and reducer need to be installed and disassembled daily, over time, the support, reducer, and mounting holes all suffer severe wear, requiring the use of tenons for reinforcement, which is inconvenient. Furthermore, during the installation and disassembly process, bamboo and wood chips are easily splashed onto the wet paper, affecting the quality of the paper. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for paper-collecting screens, which not only facilitates the disassembly and assembly of the first positioning plate and the second positioning plate, but is also not easily damaged by frequent disassembly and assembly.

[0005] This utility model can be achieved through the following technical solution: a positioning device for a paper tray, wherein a first positioning plate and a second positioning plate arranged vertically are respectively placed at the corners of both ends of one side of a paper-sticking support. The first positioning plate is an angle steel profile. The first plate and the second positioning plate are parallel to the side length of the side they are on. The second plate of the first positioning plate is parallel to the side length of the adjacent side of the side it is on. The lower ends of the first positioning plate and the second positioning plate have connecting feet that are flat along the surface of the paper-sticking support. The extending direction of the connecting feet points to the edge of the paper-sticking support. The two ends of the pressure plate that covers the connecting feet are bolted to the paper-sticking support.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The first and second positioning plates are supported by connecting foot plates, and then the first and second positioning plates are fixed by pressure plates and bolts. This makes it easy for paper feeders to disassemble and assemble the first and second positioning plates, and frequent disassembly and assembly will not cause serious wear to the first and second positioning plates. The first and second positioning plates have a long service life. Attached Figure Description

[0013] Please see Figure 1-5 As shown, a positioning device for a paper tray includes a vertically arranged first positioning plate 10 and a second positioning plate 20 positioned at the corners of one end of a paper-sticking platform A. The first positioning plate 10 is an angle steel profile. The surfaces of the first plate 10a and the second positioning plate 20 are parallel to the side length of their respective sides. The second plate 10b of the first positioning plate 10 is parallel to the side length of its adjacent side. The lower ends of the first positioning plate 10 and the second positioning plate 20 have connecting feet that lie flat along the surface of the paper-sticking platform A. The extending direction of the connecting feet points towards the edge of the paper-sticking platform A. A pressure plate is pressed onto the connecting feet. Both ends are bolted to the paper-sticking tray A; the first positioning plate 10, the second positioning plate 20 and the pressure plate are all made of 304 stainless steel, which is durable and will not cause serious wear to the first positioning plate 10 and the second positioning plate 20 due to frequent disassembly and assembly. No debris will be generated during installation and disassembly. When installing the first positioning plate 10, the connecting feet of the first positioning plate 10 and the connecting feet of the second positioning plate 20 are attached to the table surface of the paper-sticking tray A. The pressure plate cover is pressed on the connecting feet, and the cover plate is fixed to the paper-sticking tray A with bolts, thereby realizing the installation of the first positioning plate 10 and the second positioning plate 20.

[0014] The lower ends of the first plate 10a and the second plate 10b of the first positioning plate 10 are respectively provided with a first connecting foot plate 11a and a second connecting foot plate 11b; the first connecting foot plate 11a and the second connecting foot plate 11b together form a support for the first positioning plate 10, and also increase the contact area between the first positioning plate 10 and the paper mounting tray A, which is beneficial to improving the stability of the first positioning plate 10 when pre-positioning.

[0015] The paper-mounting tray A has a first positioning short post 30 that is inserted into a positioning hole on the second connecting foot plate 11b for positioning. A first pressure plate 40 is pressed onto the first connecting foot plate 11a. The first positioning short post 30 is used to accurately position the first positioning plate 10 on the paper-mounting tray A, which facilitates the subsequent fixation of the first connecting foot plate 11a by the first pressure plate 40. The first positioning short post 30 has a non-circular cross section and can be rectangular to prevent the second connecting foot plate 11b from rotating around the first positioning short post 30 after the first positioning short post 30 is inserted into the positioning hole on the second connecting foot plate 11b. This ensures that the surface of the first plate 10a is parallel to the side length of the side where the paper-mounting tray A is located, and the second plate 10b is parallel to the side length of the adjacent side of the side where the paper-mounting tray A is located.

[0016] The third connecting foot plate 21 at the connection between the second positioning plate 20 and its lower end is provided with a positioning hole, which is inserted and positioned in conjunction with the second positioning short post 50 on the paper mounting tray A. The second pressure plate 60 is pressed on the third connecting foot plate 21. The function of the second positioning short post 50 is the same as that of the first positioning short post 30 mentioned above.

[0017] One end of the first pressure plate 40 has a through hole 41 for sliding engagement with the smooth section of the first bolt 71. The other end of the first pressure plate 40 has a notch-shaped slot 42 on the side near the first positioning plate 10 for engaging the bolt post of the second bolt 72. When the first pressure plate 40 is pressed onto the first connecting foot plate 11a, the upper surface of the first pressure plate 40 abuts against the lower side of the bolt head of the first bolt 71 and the second bolt 72, respectively. In specific implementation, the first bolt 71 is pre-inserted into the through hole 41 of the first pressure plate 40, and then the screw section of the first bolt 71 is screwed into the paper mounting tray A. The screw section of the second bolt 72 is also partially screwed into the paper mounting tray A (the first bolt 71, the first pressure plate 40, and the second bolt 72 are all pre-installed on the paper mounting tray). After inserting the first positioning short post 30 into the positioning hole on the second connecting foot plate 11b, the first pressure plate 40 rotates around the outer periphery of the smooth section of the first bolt 71, thereby pressing the first pressure plate 40 onto the first connecting foot plate 11a. At the same time, the second bolt 71 is located in the bayonet 42. At this time, the upper surface of the first pressure plate 40 abuts against the lower side of the bolt head of the first bolt 71 and the second bolt 72 respectively. By turning the second bolt 72, the tightness between the first pressure plate 40 and the first connecting foot plate 11a can be adjusted, thereby facilitating the rotation of the first pressure plate 40 to the lower side of the bolt head of the second bolt 72 or away from the lower side of the bolt head of the second bolt 72. Therefore, the entire disassembly and assembly process is relatively simple and easier to operate.

[0018] Furthermore, a shim 80 is provided on the top surface of the paper mounting tray A near the through hole 41, which is in a sliding fit with the first pressure plate 40. The thickness of the shim 80 is equal to the thickness of the first connecting foot plate 11a. By providing the shim 80, the first pressure plate 40, which is sleeved on the bare section of the first bolt 71, can be prevented from sliding down. Thus, when driving the first pressure plate 40 to rotate around the first bolt 71, it is not necessary to adjust the height of the first pressure plate 40, which further simplifies the operation steps. At the same time, it can also avoid the problem of damage to the threads on the surface of the first bolt 71 caused by adjusting the height of the first pressure plate 40 after it slides down.

[0019] The connection structure of the first pressure plate 40 and the second pressure plate 60 is the same; the structure of the second pressure plate 60 is the same as that of the first pressure plate 40. The paper mounting tray A is also provided with the first bolt 71 and the second bolt 72 at the location of the second pressure plate 60. The structural features between the second pressure plate 60, the first bolt 71, the second bolt 72, and the paper mounting tray A are also the same as those of the first pressure plate 40.
