Description

Technical Field

[0001] This utility model relates to the field of metal mesh leveling technology, specifically to a high-efficiency metal mesh unwinding and leveling device. Background Technology

[0002] In daily life, we often see metal protective nets, which serve to limit and isolate. After the metal net is woven, before it enters subsequent processing (such as cleaning, coating, winding, stamping, etc.), the surface of the metal net needs to be cleaned and flattened. At this time, the metal net needs to be unwound and flattened.

[0003] Patent application CN202121680319.5 discloses a reciprocating scraper powder cleaning and recovery device for online powder coating of metal wire mesh, belonging to the field of metal wire mesh processing. The device includes a long and narrow tank with a ramp at the upper inlet. Inside the tank is a screw mounting seat with a screw movably mounted on it. One end of the screw is connected to the output shaft of a drive motor via a coupling. A scraper is mounted on the screw. Powder outlets are located at both ends of the tank, connected to a powder collection bin via a connecting hose. This invention, due to its reciprocating screw structure, ensures that activating the powder cleaning device during wire mesh coating does not affect the coating effect. It is easy to use, can be set to start periodically, and can perform powder cleaning unattended. The cleaned plastic powder is automatically collected into the powder collection bin, making replacement convenient. The device has high cleaning efficiency, requiring only a few cycles to achieve good cleaning results without powder diffusion or leakage, ensuring worker respiratory safety and a comfortable working environment.

[0004] However, the application no longer allows for the flattening of the metal mesh during unwinding, affecting the processing efficiency of the metal mesh.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency metal mesh unwinding and leveling device that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: A high-efficiency metal mesh unwinding and leveling device includes: a frame; a motor fixedly mounted on the frame; a winding roller for unwinding the metal mesh; and a leveling assembly for leveling the metal mesh. The leveling assembly includes: a fixed roller; a scraper fixedly mounted on the fixed roller; a connecting shaft fixedly mounted on the fixed roller; a pressure roller fixedly mounted on the connecting shaft; a positioning groove formed on the pressure roller; a threaded rod one threadedly mounted on the frame; a turntable fixedly mounted on the threaded rod one; a fixed plate slidably mounted on the threaded rod one; and a threaded rod two threadedly connected to the fixed plate.

[0008] Furthermore, the fixed roller is slidably mounted on the frame; the threaded rod is threadedly connected to the frame.

[0009] Furthermore, the pressure roller is slidably connected to the frame; a spring is fixedly installed on the fixed plate.

[0010] Furthermore, the roller comprises: a rotating shaft fixedly mounted on the output shaft of the motor; an adjusting sleeve slidably mounted on the rotating shaft; a hinge rod hinged to the adjusting sleeve; a connecting block rotatably mounted on the hinge rod; and an outer support sleeve fixedly mounted on the connecting block.

[0011] Furthermore, multiple sets of the adjusting sleeves are arranged along the axis of rotation, and adjusting rods are threadedly connected to adjacent sets of adjusting sleeves; the adjusting rods are provided with slots.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a high-efficiency metal mesh unwinding and leveling device. By rotating the second threaded rod, the fixed plate is moved on the first threaded rod for position adjustment. When the fixed plate moves, it drives the spring to move synchronously. When the spring contacts the pressure roller, the second threaded rod continues to rotate, causing the pressure roller to contact the winding roller. At this time, the fixed roller drives the scraper to move to the surface of the metal mesh. The scraper cleans the surface of the metal mesh, while the pressure roller squeezes the metal mesh to prevent the metal mesh from loosening during unwinding and affecting the unwinding of the metal mesh.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 4 As shown, this utility model discloses a high-efficiency metal mesh unwinding and leveling device, comprising: a frame 1; a motor 2 fixedly installed on the frame 1; a winding roller 3 for unwinding the metal mesh; and a leveling component 4 for leveling the metal mesh. The motor 2 drives the winding roller 3 to rotate, thereby realizing the unwinding of the metal mesh, and the leveling component 4 can clean the metal mesh during the unwinding process.

[0022] Specifically, the leveling assembly 4 includes: a fixed roller 41, which is slidably mounted on the frame 1; a scraper 42 fixedly mounted on the fixed roller 41; a connecting shaft 43 fixedly mounted on the fixed roller 41; a pressure roller 44 fixedly mounted on the connecting shaft 43, which is slidably connected to the frame 1; a positioning groove 45 formed on the pressure roller 44; a threaded rod 47 threadedly mounted on the frame 1; a turntable 46 fixedly mounted on the threaded rod 47; a fixing plate 48 slidably mounted on the threaded rod 47; and a threaded rod 410 threadedly connected to the fixing plate 48, which is threadedly connected to the frame 1. A spring 49 is fixedly mounted on the fixing plate 48.

[0023] First, rotate the second threaded rod 410 to drive the fixed plate 48 to adjust its position on the first threaded rod 47. When the fixed plate 48 moves, it drives the spring 49 to move synchronously. When the spring 49 contacts the pressure roller 44, the second threaded rod 410 continues to rotate, driving the pressure roller 44 to contact the winding roller 3. At this time, the fixed roller 41 drives the scraper 42 to move to the surface of the metal mesh. The scraper 42 cleans the surface of the metal mesh, while the pressure roller 44 squeezes the metal mesh to prevent it from loosening when unwinding, which would affect the unwinding of the metal mesh. In use, the motor 2 drives the winding roller 3 to rotate, and the metal mesh is unwound from the winding roller 3 by hand.

[0024] Specifically, motor 2 drives roller 3 to rotate, causing the tightly wound metal mesh on roller 3 to loosen. At this time, the metal mesh is manually pulled outward to unwind it. Conversely, when motor 2 reverses, it winds the metal mesh back onto roller 3, thus collecting it.

[0025] When the metal mesh needs to be wound up, the length of the metal mesh wound on the winding roller 3 varies and the thickness of the winding roller 3 varies according to production requirements. Therefore, the turntable 46 is manually rotated to drive the threaded rod 47 to rotate, which in turn drives the threaded rod 47 to be adjusted inside the pressure roller 44 through the positioning groove 45. After the winding roller 3 winds the metal mesh, the winding roller 3 pushes the pressure roller 44 to move. At the same time, the pressure roller 44 moves on the threaded rod 47 through the positioning groove 45. When the threaded rod 47 contacts the bottom of the positioning groove 45, the pressure roller 44 cannot move. At this time, the winding of the metal mesh stops, thereby realizing the adjustment of the winding amount of the metal mesh.

[0026] The winding roller 3 consists of: a rotating shaft 31 fixedly mounted on the output shaft of the motor 2; an adjusting sleeve 32 slidably mounted on the rotating shaft 31; a hinge rod 33 hinged to the adjusting sleeve 32; a connecting block 34 rotatably mounted on the hinge rod 33; and an outer support sleeve 35 fixedly mounted on the connecting block 34. Multiple sets of adjusting sleeves 32 are arranged along the axial direction of the rotating shaft 31, and adjacent sets of adjusting sleeves 32 are threadedly connected to adjusting rods 36. The adjusting rods 36 are threadedly connected to the adjusting sleeves 32 via bolts passing through slots 37. The adjusting rods 36 have slots 37. When the motor 2 drives the rotating shaft 31 to rotate, the metal mesh on the outer support sleeve 35 can be unloaded or wound up.

[0027] It should be noted that the hinge rods 33 on the two adjacent sets of adjusting sleeves 32 are tilted in opposite directions. When the diameter of the roller 3 needs to be adjusted, the two adjacent sets of adjusting sleeves 32 are pushed to slide relative to each other on the rotating shaft 31. This allows the adjusting sleeves 32 to drive the connecting block 34 and the outer support sleeve 35 to be adjusted through the hinge rods 33. For example, when the two sets of adjusting sleeves 32 are close to each other, the outer support sleeve 35 opens outward and the diameter increases. When the two sets of adjusting sleeves 32 are far apart, the outer support sleeve 35 contracts inward and the diameter decreases. This is beneficial for adjustment according to production needs.

[0028] Before adjusting the adjusting sleeve 32, the bolt needs to be loosened first, and then the adjusting sleeve 32 is pushed on the rotating shaft 31 for adjustment. At this time, the adjusting sleeve 32 drives the bolt to slide on the slot 37. After the adjustment is completed, the bolt is rotated to fix it, thus achieving the fixed work after adjustment.

[0029] Working principle: First, rotate the second threaded rod 410 to drive the fixed plate 48 to adjust its position on the first threaded rod 47. When the fixed plate 48 moves, it drives the spring 49 to move synchronously. When the spring 49 contacts the pressure roller 44, the second threaded rod 410 continues to rotate, driving the pressure roller 44 to contact the winding roller 3. At this time, the fixed roller 41 drives the scraper 42 to move to the surface of the metal mesh. The scraper 42 cleans the surface of the metal mesh, while the pressure roller 44 squeezes the metal mesh. When it is necessary to adjust the diameter of the winding roller 3, push the two sets of adjacent adjusting sleeves 32 to slide relative to each other on the rotating shaft 31, so that the adjusting sleeves 32 drive the connecting block 34 and the outer support sleeve 35 to adjust through the hinge rod 33.
