Description

Technical Field

[0001] This utility model belongs to the technical field of carbon fiber cloth production equipment, specifically a scratch-resistant device for carbon fiber cloth production. Background Technology

[0002] Carbon fiber cloth, also known as carbon fiber cloth or carbon fiber fabric, is a unidirectional carbon fiber reinforcement product woven from 12K carbon fiber filaments. This material is combined with concrete components through matching impregnation adhesive and is widely used for tensile, shear and seismic reinforcement of civil engineering structures such as buildings, bridges and tunnels. In the production process of carbon fiber prepreg, excess epoxy resin on the carbon fiber needs to be scraped off to ensure the smoothness and aesthetics of the prepreg surface.

[0003] In a Chinese patent for an anti-scratch device for carbon fiber prepreg production (authorization public number: CN221496747U), the device includes two vertical plates and carbon fiber cloth. A drive roller, a driven roller, and a drive rod are rotatably connected between the two vertical plates. A tension roller is fixed between the two vertical plates. One end of the carbon fiber cloth is sequentially driven and connected to the outer wall of the drive roller, tension roller, and driven roller. A motor 1 and a motor 2 are fixed to the outer wall of one of the vertical plates. The output end of motor 1 passes through the side wall of the vertical plate and is fixed to the drive roller. The output end of motor 2 passes through the side wall of the vertical plate and is fixed to the drive rod. In the prior art, the production device for carbon fiber prepreg has the problem that the epoxy resin, which adheres tightly to the carbon fiber, can easily damage the structure of the carbon fiber during the resin scraping process, thereby reducing the quality of the carbon fiber prepreg. However, the carbon fiber cloth is prone to bending and wrinkling during the production and conveying process, resulting in insufficient flatness and uniformity of the carbon fiber cloth surface in contact with the scraper, which affects the scraping effect on the carbon fiber cloth surface and easily causes scratches. Summary of the Invention

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a scratch-resistant device for carbon fiber cloth production, comprising a workbench, with a flattening mechanism fixedly connected to both ends of the upper surface of the workbench for preventing wrinkles in the carbon fiber cloth, and a scraper machine fixedly connected to the middle of the upper surface of the workbench for scraping the upper surface of the carbon fiber cloth, and a tensioning mechanism fixedly connected to the upper surface of the workbench between each of the flattening mechanism and the scraper machine.

[0005] The leveling mechanism includes a strip shell fixed to the surface of the workbench. A first motor is fixedly connected to the front end of the strip shell. A bidirectional lead screw is fixedly connected to the main shaft end of the first motor. Two symmetrically arranged nut sleeves are threaded onto the bidirectional lead screw. Two symmetrically arranged U-shaped frames are fixedly connected to both sides of each nut sleeve. Openings are provided on both side walls of the strip shell. Two sets of U-shaped frames pass through the two openings and are fixedly connected to two symmetrically arranged movable seats. Vertical frames are fixedly connected to the two movable seats. Two symmetrically arranged slotted shells are fixedly connected to the upper ends of the two vertical frames. A horizontally arranged miniature push rod is fixedly connected to the outer wall of the slotted shell. One end of the miniature push rod passes through the slotted shell and is fixedly connected to a movable plate. A vertically arranged support rod is fixedly connected to the inner wall of the slotted shell. Two sliding sleeves are slidably sleeved on the support rod. A sliding pin is fixedly connected to one side of each of the two sliding sleeves. Two inclined symmetrical sliding slots are provided on the side wall of the movable plate. The two sliding pins pass through the two sliding slots respectively. A clamping roller is rotatably connected to one side of each of the two sliding sleeves via a rotating shaft.

[0006] As a further embodiment of this utility model: the tensioning mechanism includes a concave shell fixed to the upper surface of the workbench, a second motor fixedly connected to one side of the concave shell, a rotating rod fixedly connected to the main shaft end of the second motor, two driving bevel gears fixedly connected to the rotating rod, threaded rods rotatably connected to the inner walls of the two vertical sections of the concave shell, a driven bevel gear meshing with a driving bevel gear fixedly connected to the lower end of each threaded rod, a nut block threadedly connected to each threaded rod, a mounting bracket fixedly connected to the opposite side of the two nut blocks, a pressure sensor fixedly connected to the inner top wall of the two mounting brackets, a mounting sleeve fixedly connected to the lower end of the pressure sensor, and a tensioning roller rotatably connected between the two mounting sleeves.

[0007] As a further embodiment of this utility model: the inner walls on both sides of the groove are frictionally connected to the side walls on both sides of the sliding pin.

[0008] As a further improvement of this invention, rubber sleeves are fixedly fitted onto the outer walls of both clamping rollers.

[0009] As a further embodiment of this utility model, the inner walls of the upper and lower sides of the opening are frictionally connected to the side walls of the U-shaped frame.

[0010] As a further embodiment of this utility model: a control panel is fixedly connected to one side of the workbench, and the control panel is electrically connected to the leveling mechanism, the scraper, and the tensioning mechanism respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting up a flattening mechanism, starts the first motor to drive the bidirectional lead screw to rotate. At this time, the two nut sleeves move closer or further apart, thereby driving the two vertical frames on the two moving seats to move closer or further apart, realizing the spacing adjustment. After adjustment, the two sides of the carbon fiber cloth are placed between the two sets of clamping rollers respectively. The micro push rod is started to extend, which can push the moving plate forward. At this time, the two sliding pins move towards each other along the two sliding grooves, thereby driving the two sliding sleeves to move towards each other on the support rod, which can then drive the two clamping rollers to clamp the edge of the carbon fiber cloth, thereby clamping and positioning the two sides of the carbon fiber cloth. This allows the carbon fiber cloth to be flattened during the conveying process, preventing the carbon fiber cloth from bending and wrinkling, thus avoiding the drawback of scratches.

[0013] 2. This utility model, by setting a tensioning mechanism, allows the pressure sensor to monitor the tension force of the tensioning roller on the carbon fiber cloth. After presetting a suitable pressure value, the second motor is started, driving the rotating rod to rotate. Since the two active bevel gears mesh with the two driven bevel gears respectively, the two threaded rods are driven to rotate synchronously. At this time, the two nut blocks rise or fall synchronously, thereby controlling the lifting and lowering adjustment of the tensioning roller, thus adjusting the tension force on the carbon fiber cloth and ensuring the stability of the carbon fiber cloth during conveying.

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] Please see Figures 1-6 This embodiment provides a scratch-resistant device for carbon fiber cloth production, which includes a workbench 1. Both ends of the upper surface of the workbench 1 are fixedly connected to a flattening mechanism for preventing wrinkles in the carbon fiber cloth. A scraper machine for scraping the upper surface of the carbon fiber cloth is fixedly connected to the middle of the upper surface of the workbench 1. This is a common device, which includes a concave frame with a telescopic cylinder installed on it. A scraper is installed at the lower end of the telescopic cylinder. A tensioning mechanism is fixedly connected to the upper surface of the workbench 1 between each flattening mechanism and the scraper machine. The device has a high degree of automation.

[0024] The leveling mechanism includes a strip shell 3 fixed to the upper surface of the workbench 1. A first motor 4 is fixedly connected to the front end of the strip shell 3. A double-acting lead screw 5 is fixedly connected to the spindle end of the first motor 4. Two symmetrically arranged nut sleeves 6 are threaded onto the double-acting lead screw 5. Two symmetrically arranged U-shaped frames 7 are fixedly connected to both sides of each nut sleeve 6. Openings are provided on both side walls of the strip shell 3. The two sets of U-shaped frames 7 pass through the two openings and are fixedly connected to two symmetrically arranged movable seats 8. Vertical frames 9 are fixedly connected to the two movable seats 8. Two symmetrically arranged vertical frames 9 are fixedly connected to the upper ends of the two vertical frames 9. The groove shell 11 has a horizontally arranged miniature push rod 12 fixedly connected to the outer wall of the groove shell 11. One end of the miniature push rod 12 passes through the groove shell 11 and is fixedly connected to a moving plate 13. The inner wall of the groove shell 11 is fixedly connected to a vertically arranged support rod 14. Two sliding sleeves 15 are slidably sleeved on the support rod 14. A sliding pin 16 is fixedly connected to one side of each of the two sliding sleeves 15. The side wall of the moving plate 13 has two inclined and symmetrically arranged sliding slots 17. The two sliding pins 16 are respectively set through the two sliding slots 17. One side of each of the two sliding sleeves 15 is rotatably connected to a clamping roller 19 through a rotating shaft 18.

[0025] When the carbon fiber cloth needs to be flattened during the conveying process, firstly, adjust the distance between the two vertical frames 9 according to the width of the carbon fiber cloth, start the first motor 4 to drive the bidirectional lead screw 5 to rotate. Since the bidirectional lead screw 5 is threadedly connected to the two nut sleeves 6 respectively, at this time, the two nut sleeves 6 are moved closer or further away, thereby driving the two vertical frames 9 on the two moving seats 8 to move closer or further away, realizing the distance adjustment. After adjustment, place the two sides of the carbon fiber cloth between the two sets of clamping rollers 19 respectively, start the micro push rod 12 to extend, which can push the moving plate 13 forward. At this time, the two sliding pins 16 move towards each other along the two sliding grooves 17, thereby driving the two sliding sleeves 15 to move towards each other on the support rod 14, which can then drive the two clamping rollers 19 to clamp the edge of the carbon fiber cloth, which can clamp and position the two sides of the carbon fiber cloth, so that the two sides of the carbon fiber cloth are flattened during the conveying process, preventing the carbon fiber cloth from bending and wrinkling, thereby avoiding the drawback of scratches.

[0026] like Figure 5 and Figure 6 As shown: The tensioning mechanism includes a concave shell 20 fixed to the upper surface of the worktable 1. A second motor 21 is fixedly connected to one side of the concave shell 20. A rotating rod 22 is fixedly connected to the spindle end of the second motor 21. Two driving bevel gears 23 are fixedly connected to the rotating rod 22. Threaded rods 24 are rotatably connected to the inner walls of the two vertical sections of the concave shell 20. A driven bevel gear 25 that meshes with one driving bevel gear 23 is fixedly connected to the lower end of each threaded rod 24. A nut block 26 is threadedly connected to each threaded rod 24. A mounting bracket 27 is fixedly connected to the opposite side of each of the two nut blocks 26. A pressure sensor 28 is fixedly connected to the inner top wall of each of the two mounting brackets 27. A mounting bracket 28 is fixedly connected to the lower end of each pressure sensor 28. The two mounting sleeves 29 are rotatably connected to a tension roller 30. When the carbon fiber cloth is conveyed, the carbon fiber cloth passes under the tension roller 30 and presses against it. The pressure sensor 28 can monitor the tension force of the tension roller 30 on the carbon fiber cloth. After presetting a suitable pressure value, the second motor 21 is started to drive the rotating rod 22 to rotate. Since the two driving bevel gears 23 mesh with the two driven bevel gears 25 respectively, they drive the two threaded rods 24 to rotate synchronously. Since the two threaded rods 24 are threadedly connected to the two nut blocks 26 respectively, the two nut blocks 26 rise or fall synchronously, thereby controlling the lifting and lowering adjustment of the tension roller 30, thereby adjusting the tension force on the carbon fiber cloth and ensuring the stability of the carbon fiber cloth during conveying.

[0027] like Figure 4 As shown: The inner walls on both sides of the groove 17 are frictionally connected to the side walls on both sides of the sliding pin 16, making the displacement of the sliding pin 16 more stable.

[0028] like Figure 2As shown: The outer side walls of the clamping rollers 19 are all fixedly fitted with rubber sleeves 10 to prevent damage to the carbon fiber cloth and to make the clamping more stable.

[0029] like Figure 2 As shown: the inner walls of the upper and lower sides of the opening are frictionally connected to the side walls of the U-shaped frame 7, making the displacement of the U-shaped frame 7 more stable.

[0030] like Figure 1 As shown: A control panel 2 is fixedly connected to one side of the workbench 1. The control panel 2 is electrically connected to the leveling mechanism, the scraper and the tensioning mechanism respectively. Each electrical device is electrically connected to the control panel 2, which is easy to operate and has an external power supply. The circuit involved is existing technology and can be fully implemented by those skilled in the art, so there is no need to elaborate.

[0031] Working principle: When the carbon fiber cloth needs to be flattened during the conveying process, firstly, the distance between the two vertical frames 9 is adjusted according to the width of the carbon fiber cloth. The first motor 4 is started to drive the bidirectional lead screw 5 to rotate. Since the bidirectional lead screw 5 is threadedly connected to the two nut sleeves 6 respectively, the two nut sleeves 6 are moved closer or further away, which in turn drives the two vertical frames 9 on the two moving seats 8 to move closer or further away, thereby realizing the distance adjustment. After adjustment, the two sides of the carbon fiber cloth are placed between the two sets of clamping rollers 19 respectively. The micro push rod 12 is started to extend, which can push the moving plate 13 forward. At this time, the two sliding pins 16 move towards each other along the two sliding grooves 17, which in turn drives the two sliding sleeves 15 to move towards each other on the support rod 14, which can then drive the two clamping rollers 19 to clamp the edge of the carbon fiber cloth. The two sides of the carbon fiber cloth can be clamped and positioned, so that the two sides of the carbon fiber cloth are flattened during the conveying process, preventing the carbon fiber cloth from bending and wrinkling, thereby avoiding the drawback of scratches.

[0032] When the carbon fiber cloth is conveyed, it passes under the tension roller 30 and presses against it. The pressure sensor 28 can monitor the tension force of the tension roller 30 on the carbon fiber cloth. After setting a suitable pressure value, the second motor 21 is started, which drives the rotating rod 22 to rotate. Since the two driving bevel gears 23 mesh with the two driven bevel gears 25 respectively, they drive the two threaded rods 24 to rotate synchronously. Since the two threaded rods 24 are threadedly connected to the two nut blocks 26 respectively, the two nut blocks 26 rise or fall synchronously, thereby controlling the lifting and lowering adjustment of the tension roller 30, thus adjusting the tension force on the carbon fiber cloth and ensuring the stability of the carbon fiber cloth during conveying.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
