Description

Technical Field

[0001] This invention relates to the field of papermaking technology, and in particular to a portable tool for repairing defects in forming wires. Background Technology

[0002] The forming wire is an important piece of equipment on a paper machine, responsible for paper sheet formation and dewatering. It dewaters the pulp suspension from the headbox and propels the paper web to subsequent processing stages. After production, forming wires sometimes develop defects, such as flaws at the binding edges. These defects can prevent the binding from properly controlling the weaving threads, leading to deformation of the woven threads and uneven wire openings, thus affecting papermaking. Traditional methods involve directly removing the forming wire or cutting off the damaged portion for repair, which is slow, costly, and inconvenient as it doesn't allow for direct repair of the binding edges. Summary of the Invention

[0003] The technical problem this invention aims to solve is to address the aforementioned technical shortcomings by providing a portable tool for repairing defects in molded mesh. This tool assists in better fixing and repairing, and its mirror-like movement makes repair more convenient and allows for easy adjustment to suit different repair needs.

[0004] The technical solution adopted in this invention is as follows: A portable molding mesh defect repair tool is provided, comprising two "U"-shaped frames, with the right ends of the two frames rotatably connected via a pivot. Two mounting strips are fixedly connected to the right end of the lower frame; two fixing plates are fixedly connected to the right end of the upper frame; fixing bolts are threaded onto the mounting strips at the lower ends of the two fixing plates; a slide rail is slidably connected to the two mounting strips; a slider is slidably connected to the slide rail; two telescopic rods are fixedly connected to the left end of the slider; four rotating shafts are arranged between the two telescopic rods; two rotating shafts are respectively located at the left and right ends of the two telescopic rods; three positioning rods are rotatably connected to the right rotating shaft; the upper end of the middle positioning rod is connected to...

[0006] To further optimize this technical solution, auxiliary rods are fixedly connected to the hand handle of the portable molding mesh defect repair tool; camera modules with contact heads are installed on the auxiliary rods; lighting lamps are fixedly connected to the outside of the camera modules; and a display screen that works with the camera modules is damped and rotated on the frame.

[0007] To further optimize this technical solution, both frames of the portable molding mesh defect repair tool are equipped with positioning devices. The upper positioning device includes two inner rods rotatably connected to the left end of the frame. The inner rods are located at both the front and rear ends of the frame. Outer rods are slidably sleeved on the outer sides of the inner rods. The other ends of the two outer rods are fixedly connected to locking rods. Tightening bolts that cooperate with the inner rods are provided on the outer rods. At the outer rods, sliding plates are damped and slidably connected to the frame in the front-back direction. Positioning bolts that cooperate with the outer rods are threadedly connected to the sliding plates. Rubber heads are fixedly connected to the lower ends of the positioning bolts. The lower and upper positioning devices are symmetrical and have the same structure.

[0008] To further optimize this technical solution, the two frames of the portable molding mesh defect repair tool have mesh edge grooves on the adjacent sides of their right sides; rubber pads are installed in the mesh edge grooves; and anti-slip particles are set on the rubber pads.

[0009] To further optimize this technical solution, a control groove is provided at one end of the adjustment shaft of the portable molding mesh defect repair tool.

[0010] To further optimize this technical solution, the upper end of the fixing bolts of the portable molding mesh defect repair tool is rotatably connected to a top plate via a rotating shaft.

The lower ends of the two positioning rods 9 are rotatably connected to the lower rotating shaft 8; a connecting rod 10 is rotatably connected to the lower rotating shaft 8 between the two positioning rods 9; the middle of the connecting rod 10 is rotatably connected to the left rotating shaft 8; two adjusting rods 11 are rotatably connected to the upper rotating shaft 8 on the outside of the positioning rods 9; the middle of the adjusting rod 11 is rotatably connected to the left rotating shaft 8; the adjusting rod 11 is slidably connected to the upper and left rotating shafts 8 respectively; an adjusting shaft 12 is provided between the two adjusting rods 11; the adjusting shaft 12 and its outer side are respectively provided with a forward thread 13 and a reverse thread 14, which are threaded to the adjusting rods 11 respectively; a handheld handle 15 is fixedly connected to the left end of both the adjusting rod 11 and the connecting rod 10; and a handheld handle 15 is provided on the adjacent sides of the handheld handle 15. An auxiliary device is provided; the auxiliary device includes a drive motor 16 mounted on the handheld lever 15; the other end of each drive motor 16 is fixedly connected to a contact head 17; three auxiliary blocks 18 are evenly distributed on the outer side of each contact head 17; the three auxiliary blocks 18 are respectively strip-shaped, wave-shaped, and two hemispherical protrusions; auxiliary rods 19 are fixedly connected to each handheld lever 15; camera modules 20 cooperating with the contact heads 17 are installed on each auxiliary rod 19; lighting lamps 21 are fixedly connected to the outer side of each camera module 20; a display screen 22 cooperating with the camera module 20 is damped and rotatably connected to the frame 1; positioning devices are provided on both frames 1; the upper positioning device includes two inner rods 23 rotatably connected to the left end of the frame 1; the inner rods 23 are located at the front and rear ends of the frame 1; Outer rods 24 are slidably sleeved on the outer side of rod 23; the other end of each outer rod 24 is fixedly connected to a locking rod 25; a tightening bolt 26 that mates with the inner rod 23 is provided on the outer rod 24; at the outer rod 24, a sliding plate 27 is damped and slidably connected to the frame 1 in the front-back direction; a positioning bolt 28 that mates with the outer rod 24 is threadedly connected to the sliding plate 27; a rubber head 29 is fixedly connected to the lower end of each positioning bolt 28; the lower positioning device and the upper positioning device are symmetrical and have the same structure; mesh edge grooves 30 are opened on the adjacent right sides of the two frame bodies 1; rubber pads 31 are installed in the mesh edge grooves 30; anti-slip particles 32 are provided on each rubber pad 31; a control groove 33 is opened at one end of the adjusting shaft 12; a top plate 34 is rotatably connected to the upper end of each fixing bolt 4 via a rotating shaft.

[0025] The specific structure of the convex shape is as follows: Figure 5 As shown;

[0026] Sometimes, the produced paper forming wire may have certain defects, such as defects at the edge of the forming wire, which may prevent the edge from properly limiting the weaving of the forming wire. This can cause the weaving of the forming wire to deform, resulting in uneven wire opening and affecting papermaking. Traditionally, the forming wire is directly removed or the damaged part is cut off and repaired, which is slow and costly.

[0027] When repairing the edge of the formed mesh using this tool, first clean the area to be repaired, then remove any excess damage or residue, and then open the two rotatingly connected frames 1, as follows. Figure 6 As shown, then close both frames 1, as follows. Figure 1 As shown, the damaged part of the forming net is clamped and fixed, and the mesh edge groove 30 on the frame 1 corresponds to the edge of the forming net. The rubber pad 31 on the mesh edge groove 30 has elasticity and anti-slip properties. The mesh edge higher than the forming net is firmly fixed. Then, the fixing bolt 4 is rotated. The fixing bolt 4 drives the top plate 34 connected to it to move. The top plate 34 contacts the fixing plate 3. According to the force of the bolt, the fixing plate 3 moves. The fixing plate 3 drives the upper frame 1 to move, so that the two frame bodies 1 are clamped more tightly, making it easier to fix the forming net and assisting in better repair and use.

[0028] Then, the outer rod 24 at the inner rod 23 is extended, and the outer rod 24 drives the two clamping rods 25 to move. Through the rotational connection between the inner rod 23 and the frame 1, the clamping rods 25 can be moved easily. By sliding out the sliding plate 27, the positioning bolt 28 connected to the thread on the sliding plate 27 is moved to the upper end of the outer rod 24. Then, by rotating the positioning bolt 28, the rubber head 29 on the positioning bolt 28 contacts the outer rod 24, which facilitates positioning the outer rod 24 and applying a limiting force, so that the two outer rods 24 drive the clamping rods 25 to move close together. The clamping rods 25 clamp and fix the damaged edge of the formed mesh. Then, the clamping rods 25 are adjusted to drive the formed mesh to move, and the transverse braided threads of the damaged edge of the formed mesh are fixed and straightened. Then, the position of the clamping rods 25 is fixed by the tightening bolt 26, which facilitates the straightening of the formed mesh and facilitates subsequent repair.

[0029] At this point, the damaged part of the forming mesh has been straightened. Then, controlling the upper hand lever 15, based on the sliding connection between the slide rail 5 and the mounting strip 2, the hand lever 15 can slide and move arbitrarily in the left and right directions. Based on the sliding connection between the slider 6 and the slide rail 5, the hand lever 15 can slide and move arbitrarily in the front and back directions. According to the structure of the rotating shaft 8, positioning rod 9, connecting rod 10, and adjusting rod 11, when the upper hand lever 15 is moved, the two lower hand levers 15 will also move simultaneously in a mirror image. By controlling the upper hand lever 15, the contact head 17 is moved, and the contact head 17 contacts the braided thread of the forming mesh at the bent point. Both the upper and lower contact heads 17 will simultaneously contact the braided thread, thereby driving the braided thread to move on the straightened braided thread in the other direction, thus adjusting the braided thread of the forming mesh, facilitating the repair of the mesh edge. The hand lever 15 can move in the front, back, left, and right directions, facilitating better control and repair of the forming mesh; the damaged forming mesh... The disadvantage is that it is not easy to see clearly with the naked eye. However, the camera module 20 and the display screen 22 make it easier to observe the forming mesh, thus improving its repair and use. By controlling the adjustment shaft 12 through the control slot 33, and based on the forward and reverse threads 13 and 14 on the adjustment shaft 12, the two adjustment rods 11 will move simultaneously or repel each other when the adjustment shaft 12 is rotated through the sliding limit of the adjustment rod 11. The distance between the two adjustment rods 11 and the positioning rod 9 is always the same, and the distance between the three hand-held rods 15 is also the same. Depending on the type of forming mesh, the spacing of the weaving lines of the forming mesh is also different. By adjusting the distance between the three hand-held rods 15, it is easy to adapt to forming meshes with different spacings. Based on the setting of the three hand-held rods 15, the three points of the forming mesh can be moved simultaneously, making it easier to move and repair the forming mesh, and making it more convenient to use. By controlling the upper hand-held rod 15, the upper and lower ends of the forming mesh can be moved and repaired simultaneously, making it more convenient to use. The telescopic rod 7 is used for auxiliary positioning.

[0030] After the repair is completed, the inner rod 23 in the positioning device rotates and the outer rod 24 moves, so that the clamping rod 25 is clamped onto the repaired forming net, limiting and fixing the forming net, exposing the damaged edge. Then the forming net is sealed. After the edge sealing is completed, the two frames 1 can be removed. The camera module 20 is set up to facilitate observation and understanding of the forming net, making the repair more convenient. The handheld rod 15 can also be moved to observe other parts of the forming net, so as to know where repair is needed.

[0031] The three auxiliary blocks 18 are strip-shaped, wavy-shaped, and convex-shaped, respectively. The three auxiliary blocks 18 are rotated simultaneously by the drive motor 16. The shapes of the three auxiliary blocks 18 are always the same as those of the braided yarn. The strip-shaped blocks have a larger contact area, which makes it easier to move the braided yarn of the formed mesh. The concave part of the wavy-shaped blocks is easy to contact with a single braided yarn. The convex-shaped blocks have a smaller contact point, which is easy to contact with denser braided yarns and prevents accidental contact with other braided yarns.

[0032] The damped rotating connection of the display screen 22 can be rotated to change the angle. The rotating connection between the frame 1 and the inner rod 23 also facilitates changing the angle, making it easy to change the angle and extend and slide this tool. It is also easy to fold to reduce the area occupied, making it convenient to carry, store and use.
