Description

Technical Field

[0001] This utility model relates to the field of filter cloth production technology, specifically a cutting device for filter cloth production. Background Technology

[0002] Filter cloth is an important tool for filtering solid and liquid substances. Therefore, it is widely used in daily life and industrial production. The production and processing of filter cloth requires multiple processes. After the filter cloth is produced as a semi-finished product, the whole piece of filter cloth is wound on a fixed motor. Then, according to production requirements, the filter cloth is cut into appropriate lengths.

[0003] A search revealed a Chinese patent document disclosing a cutting device for filter cloth production [Application No.: CN202221068468.0]. This cutting device for filter cloth production includes upright plates mounted on both sides of a worktable, clamping shafts mounted on the upright plates, and clamping rollers mounted on the clamping shafts. The worktable has a clamping cavity containing a support shaft, on which a support roller is mounted. The support roller and clamping roller cooperate to clamp the filter cloth and convey it forward. A top plate is mounted on the top of the frame, and a lead screw seat is mounted on the lower surface of the top plate. A drive lead screw is installed between the lead screw seats, and a drive motor is connected to the drive lead screw. A lead screw slider is adapted to the drive lead screw, and an electric telescopic rod is connected to the lead screw slider. An adsorption plate is installed at the output end of the electric telescopic rod. The worktable also has a cutting cavity containing a cutting blade.

[0004] The device disclosed in this patent automatically performs traction cutting, keeping the operator at a safe distance from the cutting blade and improving safety. However, when the device is in use, the cutting blade always protrudes from the surface of the workbench. When the filter cloth moves on the workbench, its bottom is in direct contact with the cutting blade. The bottom of the filter cloth is easily damaged by the cutting blade. Furthermore, the long-term friction between the filter cloth and the cutting blade can also affect the sharpness of the cutting blade in subsequent use, thus affecting the effect of subsequent cutting operations. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for filter cloth production, including a workbench, and further comprising:

[0007] A winding mechanism is installed on the top of the workbench, and a vertical plate is fixedly connected to the top of the workbench. Guide rollers are rotatably connected to the upper and lower sides of the inner wall of the vertical plate.

[0009] Preferably, the winding mechanism includes a bracket, a winding roller, and a fixed motor. The bracket is fixedly connected to the top of the workbench, the winding roller rotates through the surface of the bracket, the fixed motor is fixedly connected to the surface of the bracket, and one end of the winding roller is fixedly connected to the output shaft of the fixed motor.

[0010] Preferably, the moving mechanism includes a lead screw, a servo motor, and a moving block. One end of the lead screw is rotatably connected to the inner wall of the slide groove. The servo motor is fixedly connected to the surface of the top plate. The other end of the servo motor rotatably passes through the top plate and is fixedly connected to the output shaft of the servo motor. The surface of the moving block is slidably connected to the inner wall of the slide groove. The moving block is threaded onto the surface of the lead screw. The connecting plate is fixedly connected to the bottom of the moving block.

[0011] Preferably, the lifting mechanism includes a guide rod, a lifting plate, and a first compression spring. The two ends of the guide rod are fixedly connected to the bottom of the connecting plate and the bottom of the inner wall of the U-shaped plate, respectively. The lifting plate is slidably sleeved on the surface of the guide rod. The protective frame is fixedly connected to the top of the lifting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In use, when the moving mechanism drives the connecting plate to move laterally, the lifting mechanism can drive the protective frame to move laterally. During this process, through the cooperation of the lifting plate and the squeezing plate, the cutting mechanism descends and contacts the filter cloth when it approaches it, so that the cutting mechanism can cut the filter cloth. When the cutting mechanism descends, the limiting rod and the slotting mechanism can keep the filter cloth clamped before the cutting operation begins, thereby improving the cutting effect of the cutting mechanism on the filter cloth. This solves the problem that in some current devices, when the bottom of the filter cloth is in direct contact with the blade of the cutting knife during the winding of the filter cloth, it is easy to be damaged, and the sharpness of the cutting knife blade is also easily affected.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 As shown, a cutting device for filter cloth production includes a workbench 1. A winding mechanism 2 is mounted on the top of the workbench 1 and a vertical plate 3 is fixedly connected thereto. Guide rollers 4 are rotatably connected to the upper and lower sides of the inner wall of the vertical plate 3. An outer frame 5 is fixedly connected to the bottom of the inner wall of the workbench 1. A top plate 6 is fixedly connected to the top of the outer frame 5. A sliding groove is opened on the top of the top plate 6, and a moving mechanism 7 is arranged inside the sliding groove. A connecting plate 8 is slidably connected to the bottom of the top plate 6. A U-shaped plate 9 is fixedly connected to the surface of the connecting plate 8. A lifting mechanism 10 is arranged inside the U-shaped plate 9. A protective frame 11 is arranged at the bottom of the lifting mechanism 10. A cutting mechanism 12 is installed inside the protective frame 11. The cutting mechanism 12 includes a drive motor and a blade. The drive motor drives the blade. The use of the cutting mechanism 12 is a mature existing technology and will not be described in detail here. The top of the worktable 1 has a groove 13, which is used to cooperate with the cutting mechanism 12 to cut the filter cloth and reduce the damage caused by the cutting mechanism 12 to the worktable 1. Both sides of the inner wall of the outer frame 5 are fixedly connected to the extrusion plate 14. The surface of the lifting mechanism 10 is equipped with an arc plate 15, and the bottom of the arc plate 15 is fixedly connected to the fixing frame 16. The surface of the outer frame 5 has a through groove, and the inside of the through groove is equipped with a force-bearing mechanism 17. The bottom of the force-bearing mechanism 17 is equipped with a limit rod 18. The top of the worktable 1 has a slot 19. The limit rod 18 and the slot 19 are used together to clamp the filter cloth so as to increase the flatness of the filter cloth surface when cutting the filter cloth later.

[0025] The winding mechanism 2 includes a support 201, a winding roller 202, and a fixed motor 203. The support 201 is fixedly connected to the top of the workbench 1. The winding roller 202 rotates through the surface of the support 201. The fixed motor 203 is fixedly connected to the surface of the support 201. One end of the winding roller 202 is fixedly connected to the output shaft of the fixed motor 203. When the fixed motor 203 is started, the winding roller 202 rotates to wind up the filter cloth. The filter cloth is pulled and moves between the two guide rollers 4.

[0026] The moving mechanism 7 includes a lead screw 71, a servo motor 72, and a moving block 73. One end of the lead screw 71 is rotatably connected to the inner wall of the slide. The servo motor 72 is fixedly connected to the surface of the top plate 6. The other end of the servo motor 72 rotatably passes through the top plate 6 and is fixedly connected to the output shaft of the servo motor 72. The surface of the moving block 73 is slidably connected to the inner wall of the slide. The moving block 73 is threaded onto the surface of the lead screw 71. The connecting plate 8 is fixedly connected to the bottom of the moving block 73. When the operator starts the servo motor 72, the lead screw 71 rotates, which drives the moving block 73 to move, and the connecting plate 8 moves accordingly.

[0027] The lifting mechanism 10 includes a smooth rod 101, a lifting plate 102, and a first compression spring 103. Both ends of the smooth rod 101 are fixedly connected to the bottom of the connecting plate 8 and the bottom of the inner wall of the U-shaped plate 9, respectively. The lifting plate 102 is slidably sleeved on the surface of the smooth rod 101, and its surface is slidably connected to the inner wall of the U-shaped plate 9. The top of the lifting plate 102 is in contact with the bottom of the connecting plate 8. A protective frame 11 is fixedly connected to the top of the lifting plate 102. The first compression spring 103 is sleeved on the surface of the smooth rod 101. The arc plate 15 is fixedly connected to the surface of the lifting plate 102. The top of the lifting plate 102 is in contact with the bottom of the extrusion plate 14. When the connecting plate 8 moves the U-shaped plate 9, the lifting mechanism 10 moves accordingly. At this time, the lifting plate 102 is squeezed by the extrusion plate 14, causing the protective frame 11 to drop. The cutting mechanism 12 drops accordingly and keeps approaching the filter cloth until it contacts the surface of the filter cloth. After that, under the action of the elastic force of the first compression spring 103, the lifting plate 102 resets and can drive the protective frame 11 and the cutting mechanism 12 to rise.

[0028] When the lifting plate 102 descends, the arc plate 15 descends accordingly. The fixed frame 16 cooperates with the arc plate 15 and presses against the force plate 171 so as to clamp and limit the filter cloth through the cooperation of the limiting rod 18 and the slot 19.

[0029] The force-bearing mechanism 17 includes a force-bearing plate 171, a column 172, and a second compression spring 173. The surface of the force-bearing plate 171 is slidably connected to the inner wall of the through groove. The two ends of the column 172 are fixedly connected to the top and bottom of the inner wall of the through groove, respectively. The second compression spring 173 is sleeved on the surface of the column 172. The column 172 slides through the surface of the force-bearing plate 171. The limiting rod 18 is fixedly connected to the bottom of the force-bearing plate 171. The bottom of the fixing frame 16 is in contact with the top of the force-bearing plate 171. When the fixing frame 16 descends, it presses down on the force-bearing plate 171. At this time, the limiting rod 18 descends accordingly. Afterwards, under the action of the elastic force of the second compression spring 173, the force-bearing plate 171 can be raised and reset, releasing the compression of the filter cloth by the limiting rod 18.

[0030] The top of the load-bearing plate 171 is fitted with a ball bearing 20, and the bottom of the fixed frame 16 is provided with an auxiliary groove 21. The surface of the ball bearing 20 is in contact with the inner wall of the auxiliary groove 21. Through the cooperation of the ball bearing 20 and the auxiliary groove 21, the smoothness of the fixed frame 16 when moving can be increased.

[0031] Working principle: The operator passes one end of the filter cloth through the outer frame 5 and two guide rollers 4 from below the limiting rod 18, and then fixes one end of the filter cloth to the surface of the winding roller 202. The operator then starts the fixing motor 203, which drives the winding roller 202 to rotate. The rotation of the winding roller 202 winds up the filter cloth. After winding to the appropriate length, the operator starts the servo motor 72 and the cutting mechanism 12. The lead screw 71 rotates, driving the moving block 73 to move. The connecting plate 8 then drives the C-shaped plate 9 to move, and the lifting plate... When 102 cooperates with the extrusion plate 14, it can drive the protective frame 11 and the arc plate 15 to descend. When the arc plate 15 descends, it drives the fixed frame 16 to descend. The descending fixed frame 16 extrudes the force plate 171, and the limiting rod 18 descends accordingly and cooperates with the slot 19 to clamp and limit the filter cloth. At the same time, the cutting mechanism 12 descends and continues to move to cut the filter cloth. During this process, both sides of the filter cloth being cut are clamped, which can reduce the wrinkling of the filter cloth during the cutting process and improve the cutting effect.
