DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] refer to Figure 1-Figure 10 The present invention provides a grid slitting machine, including a frame 1. For easy movement, a caster 43 is arranged at the bottom of the frame 1. A traction device 32, a transition device 33 and a cutter device 34 are arranged on the frame 1 in sequence along the conveying direction. A pressure roller device 35 is arranged above the traction device 32. After the grid is pulled out by the traction device 32, the pressure roller device 35 presses the arched grid to be flat, and then enters the cutter device 34 through the transition device 33 to shear the grid.

[0035] A further optimized solution is that the traction device 32 includes a traction shaft 2, both ends of the traction shaft 2 are fixed to the frame 1 through a second bearing seat 39, a traction wheel 3 is plugged into the traction shaft 2, and the traction shaft 2 and the traction wheel 3 are fixedly connected by a key after being plugged in, wherein the traction wheel 3 includes a plurality of traction discs 3-1 and a plurality of spacers 3-2, and the total width of the traction wheel 3 is specifically designed according to the width of the grid, the spacers 3-2 are arranged at intervals with the traction discs 3-1, and the outer diameter of the spacers 3-2 is not greater than the outer diameter of the traction disc 3-1, so that the fork 17 can be inserted into the gap between the adjacent traction discs 3-1 without colliding with the spacers 3-2, and the traction discs 3-1 in the middle position of the traction wheel 3 are circumferentially A plurality of equidistantly arranged positioning blocks 3-3 are provided on the plate, and the distance and number of adjacent positioning blocks 3-3 are determined according to the size of the plate grid. The two ends of the traction wheel 3 are connected with fixing blocks 4 by bolts, and the fixing blocks 4 are connected to the traction shaft 2 by threads. In order to improve the connection stability between the fixing blocks 4 and the traction wheel 3, a connecting rod 5 is inserted on the fixing blocks 4 and the traction wheel 3, and the end of the connecting rod 5 is fixedly connected to the fixing blocks 4. Either end of the traction shaft 2 is connected to a first drive 6 through a coupling; the first drive 6 is preferably a servo motor, and can also be other driving devices. The positioning holes on the plate grid are hooked and fixed by the positioning blocks 3-3, and the servo motor is started, and the traction wheel 3 rotates to transport the plate grid.

[0036] A further optimization scheme is that the grid after being transported by the traction wheel 3 is tilted in an arc, resulting in the accuracy after shearing not meeting the requirements. Therefore, a pressure roller device 35 is fixedly provided above the discharge side of the traction wheel 3. The pressure roller device 35 flattens the arc-shaped grid before entering the subsequent shearing process. The specific pressure roller device 35 includes a pressure roller frame 7 fixedly connected to the frame body 1, the pressure roller frame 7 is fixedly connected to the cylinder rod of the cylinder 8, the protruding rod of the cylinder 8 is fixedly connected to the lifting frame 9 by bolts, and a pressure roller 10 is fixedly connected to the lifting frame 9. A clearance groove 10-1 is provided in the middle position of the pressure roller 10, and the clearance groove 10-1 is corresponding to the positioning block 3-3. The lifting frame 9 is driven to rise and fall by the operation of the cylinder 8, and the height of the pressure roller 10 is adjusted according to the usage.

[0037] Furthermore, the lifting frame 9 includes a fixed frame 9-1 fixedly connected to the extension rod of the cylinder 8, the fixed frame 9-1 is connected to the movable frame 9-3 by an adjusting bolt 9-2, and the pressure roller 10 is arranged on the movable frame 9-3. By screwing the adjusting bolt 9-2, the distance between the movable frame 9-3 and the fixed frame 9-1 is adjusted, and then the height of the pressure roller 10 is fine-tuned.

[0038] A further optimized solution is that the pressure roller 10 in the pressure roller device 35 can only play a pressing role on the grid on the transition device 33, so that the flattened grid can smoothly transition to the cutting device 34. Specifically, the transition device 33 includes a fixed plate 11 fixed on the cutting frame 18, and there are two fixed plates 11. The fixed plate 11 is connected with a movable plate 12 by bolts. A groove matching the movable plate 12 is provided on the fixed plate 11, and a plurality of threaded holes are provided on the groove. A through hole is provided on the movable plate 12. The relative position of the fixed plate 11 and the movable plate 12 is adjusted by adjusting the position of the threaded hole and the through hole. After adjustment, it is locked and positioned by bolts. An upper transition frame 13 and a lower transition frame 14 are threadedly connected in the middle position of the two movable plates 12, and the upper transition frame 13 and / or the lower transition frame 14 have an adjustable gap in the height direction of the movable plate 12; specifically, at the height of the movable plate 12 A waist-shaped hole is provided in the direction, and bolts are passed through the waist-shaped holes to fix the upper transition frame 13 or the lower transition frame 14. The upper transition frame 13 is detachably connected to several upper transition plates 15 by bolts. The upper transition frame 13 is also provided with a waist-shaped hole, and the bolts are passed through the waist-shaped holes to connect the upper transition plate 15. The lower transition frame 14 is also provided with a waist-shaped hole, and several lower transition plates 16 and a connecting fork 17 are detachably connected by bolts passing through the waist-shaped holes. The positions of the upper transition plate 15, the lower transition plate 16 and the connecting fork 17 are fine-tuned through the design of the waist-shaped hole. Several lower transition plates 16 are integrally formed, and the connecting fork 17 is connected to the lower transition plate 16 by screws. The lower transition plate 16 and the connecting fork 17 are arranged at intervals, and the connecting fork 17 extends into the gap between the adjacent traction discs 3-1, and the deep end of the connecting fork 17 is in an arc transition. The upper surface of the connecting fork 17 can be adjusted according to the actual needs of the production site. The matching height with the upper surface of the traction wheel 3 can be adjusted.

[0039] Further optimization scheme, the cutting device 34 includes a cutting frame 18 fixedly connected to the frame body 1, and the cutting frame 18 is provided with a clamping mechanism 36, a cutting roller mechanism 37 and a conveying roller mechanism 38 from top to bottom, wherein the cutting roller mechanism 37 includes a cutting roller 19, and a rolling cutting sleeve 20 plugged with the cutting roller 19, and the cutting roller 19 and the rolling cutting sleeve 20 are positioned by a pin hole after being plugged, and a middle position of the rolling cutting sleeve 20 is also provided with a clearance groove 10-1, and the rolling cutting sleeve 20 is detachably connected to the cutting knife 20-1 in the circumferential direction by bolts, and the cutting knife 20-1 includes a cross-cutting knife and a longitudinal cutting knife, which shears the grid, and either end of the cutting roller 19 is fixedly connected to a driven gear 21, and the conveying roller 38 is fixedly connected to the driven gear 21. The conveying roller mechanism 38 includes a conveying roller 22, and a positioning block 3-3 is also circumferentially arranged in the middle position of the conveying roller 22. A driving gear 23 is fixedly connected to either end of the conveying roller 22. The driving gear 23 and the driven gear 21 are arranged on the same side, and the driving gear 23 is meshingly connected with the driven gear 21. A second drive 24 is connected to either end of the conveying roller 22. The second drive 24 is also preferably a servo motor, and can also be other driving devices. When the second drive 24 is started, the conveying roller 22 drives the plate grid to be conveyed forward, while the driving gear 23 drives the driven gear 21 to rotate, thereby driving the cutting roller 19 to rotate, so that the cutting knife 20-1 shears the plate grid.

[0040] A further optimization scheme is that the grid has a certain thickness, and there should be a certain gap between the rolling sleeve 20 and the conveying roller 22 according to the thickness of the grid. Therefore, upper support rollers 19-1 are symmetrically fixed at the left and right ends of the cutting roller 19, and the outer diameter of the upper support roller 19-1 is larger than the outer diameter of the rolling sleeve 20. Lower support rollers 22-1 are symmetrically arranged at both ends of the conveying roller 22, and the lower support roller 22-1 is arranged below the upper support roller 19-1. The upper support roller 19-1 is integrally formed with the cutting roller 19, and the lower support roller 22-1 is integrally formed with the conveying roller 22. After the upper support roller 19-1 and the lower support roller 22-1 are tightly attached, there will be a certain gap between the rolling sleeve 20 and the conveying roller 22 for the grid to pass through.

[0041] Furthermore, for the convenience of installation, a first bearing seat 25 is provided at both ends of the cutting roller 19 and the conveying roller 22, a guide groove 25-1 is provided on the first bearing seat 25, and a clamping groove 18-1 adapted to the guide groove 25-1 is provided on the cutting frame 18, and a positioning plate 26 is clamped in the guide groove 25-1. The conveying roller 22 is first placed in the use position along the clamping groove 18-1 through the guide groove 25-1, and then the cutting roller 19 is placed in the corresponding position along the clamping groove 18-1, so that the upper support roller 19-1 is tightly attached to the lower support roller 22-1. After adjustment, it is fixed to the cutting frame 18 by bolts through the positioning plate 26. The positioning plate 26 also plays a protective role to prevent debris from entering the shearing area.

[0042] Furthermore, in order to prevent the cutting roller 19 from jumping upward due to insecure positioning during the shearing process, a clamping mechanism 36 is provided on the upper support roller 19-1, and the clamping mechanism 36 includes a clamping frame 27 fixed to the top of the cutting frame 18 and connected by bolts, and a clamping wheel group is connected to the clamping frame 27 by a clamping bolt 27-1, and the clamping wheel group is arranged corresponding to the upper support roller 19-1, and the clamping wheel group includes a clamping wheel frame 28, and two clamping wheels 29 are arranged on the clamping wheel frame 28, and the clamping wheel 29 is arranged in close contact with the upper support roller 19-1, and the clamping force of the clamping wheel 29 is adjusted by screwing the clamping bolt 27-1.

[0043] Furthermore, the cutting roller 19 and the conveying roller 22 on the cutting device 34 will generate great vibration during actual operation, so springs 40 are fixedly provided at both ends of the cutting roller 19 and the conveying roller 22. The spring 40 can reduce the vibration of the cutting roller 19 and the conveying roller 22 during the process of shearing the plate grid, thereby increasing the shearing accuracy.

[0044] A further optimization scheme is provided on the frame 1, and the scraper mechanism includes a scraper frame 30 fixedly connected to the frame 1, and a scraper 31 is fixed on the scraper frame 30. There are five scraper mechanisms, one is provided at each of the upper support roller 19-1 and the lower support roller 22-1, and one is provided at the conveying roller 22. The scrapers 31 are respectively in close contact with the upper support roller 19-1, the lower support roller 22-1 and the conveying roller 22 to clean the lead paste, debris and dust and improve the shearing accuracy.

[0045] Furthermore, a wiping mechanism is provided on one side of the upper support roller 19-1 and the lower support roller 22-1 corresponding to the scraper mechanism. The wiping mechanism includes a wiping frame 41 fixed on the cutting frame 18 and a wiping member 42 connected to the wiping frame 41. The wiping member 42 is preferably cotton cloth, but can also be other soft cleaning or wiping materials. The wiping member 42 wipes the lead paste and debris on the upper support roller 19-1 and the lower support roller 22-1 to prevent the lead paste from being too thick or debris from entering the gap between the upper support roller 19-1 and the lower support roller 22-1, thereby affecting the shearing accuracy.

[0046] The present invention uses the precise traction of the traction device, and then uses the pressure roller device to press the grid passing through the traction wheel from the bow shape to flatness, and uses the guiding effect of the transition device to keep the grid reaching the cutting knife device in a horizontal state, which greatly increases the accuracy of slitting. There is no need to add a flattening device to level the grid later. During the whole process, the grid and the lead paste will not separate, thereby improving the disadvantages of inaccurate positioning and size cutting errors in the traditional equipment that only uses the roller shear device to achieve positioning and shearing, and the product performance is improved. In addition, the grid slitting device of the present invention is a two-body power, the traction device is a separate drive, and the slitting device is a separate drive. Through the adjustment of the electrical system, these two drives can be adjusted and coordinated separately to achieve the purpose of accurately slitting the grid, improving the disadvantage that the slitting position must be adjusted by manual mechanical adjustment of the gears in the traditional equipment, which easily leads to the final slitting accuracy. Therefore, the two-body power increases the flatness of the grid while enabling the mesh belt to achieve accurate slitting, stable speed, and improved efficiency.

[0047] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0048] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
