DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0035] Example 1

[0036] This embodiment 1 provides a manual shearing device for carbon fiber cloth, such as Figure 1-Figure 3 Shown, including:

[0037] Workbench 1 provides a platform for shearing work. Specifically, workbench 1 is a square structure, and its bottom is provided with supporting legs for support.

[0038] The top of the workbench 1 is provided with a support frame 2, and a placing roller 3 is rotatably arranged on the support frame 2; the placing roller 3 is located at the right side of the support frame 2, and is used for placing the carbon fiber cloth to be cut.

[0039] The fixing assembly 4 is arranged on the workbench 1, and includes a support block 41 and a positioning adhesive plate 42,

[0040] The support block 41 is arranged on the workbench 1; the support block 41 is used for supporting the positioning adhesive plate 42 and is arranged at the left side of the workbench 1.

[0041] The number of the positioning adhesive plates 42 is two, and the two positioning adhesive plates 42 are arranged at the two sides of the support block 41 respectively; after the carbon fiber cloth is pulled to the left side of the workbench 1, the carbon fiber cloth is bonded to the two positioning adhesive plates 42, at this time, the position of the carbon fiber cloth is fixed to a certain extent, so that the stability of the position of the carbon fiber cloth in the cutting process is ensured, and cutting inaccuracy caused by movement or deformation is avoided.

[0042] The cutting assembly 5 is arranged between the two positioning adhesive plates 42 and is used for cutting the carbon fiber cloth; after the carbon fiber cloth is fixed by the two positioning adhesive plates 42, at this time, the cutting position of the carbon fiber cloth is in a taut state, and the cutting assembly 5 can be smoothly and easily cut between the two positioning adhesive plates 42.

[0043] Further, as shown in the drawings, Figure 2 The cutting assembly 5 includes a rotating block 51, a moving blade 52 and a fixed blade 53,

[0044] One end of the rotating block 51 is rotatably arranged on the support block 41 through a rotating shaft 54, and the rotating block 51 is located between the two positioning adhesive plates 42;

[0045] The moving blade 52 is fixedly arranged at the bottom of the rotating block 51; specifically, a placing groove is formed at the bottom of the rotating block 51, and the moving blade 52 is fixedly arranged in the placing groove, so as to ensure the safety of the moving blade 52.

[0046] The fixed blade 53 is arranged on the support block 41, and the fixed blade 53 cooperates with the moving blade 52 to cut the carbon fiber cloth. Specifically, a blade groove 411 is formed at the top of the support block 41, and the blade groove 411 is used for placing the fixed blade 53 and the moving blade 52. The fixed blade 53 is fixedly arranged in the blade groove 411, so as to avoid injury caused by accidental touch of the staff, and at the same time, the rotating block 51 drives the moving blade 52 to rotate, and finally falls into the blade groove 411 after cutting is completed, so as to protect the moving blade 52 and the fixed blade 53 to a certain extent.

[0047] In this embodiment, both the fixed blade 53 and the movable blade 52 are made of a high-hardness, wear-resistant material, and their shape and sharpness are customized according to the thickness and hardness of the carbon fiber cloth. This design ensures the stability and durability of the blades during the shearing process, while also improving the accuracy and efficiency of the shearing.

[0048] Specifically, the specific working process of the shearing component 5 is:

[0049] The staff holds the end of the rotating block 51 away from the rotating shaft 54. The rotating block 51 rotates and drives the movable blade 52 to move at the same time. After moving downward, the staff applies force to the movable blade 52, which now contacts the carbon fiber cloth. Due to the excessive pressure, the carbon fiber cloth can be easily cut. In addition, the fixed blade 53 can be used for assistance. That is, when the carbon fiber cloth contacts the fixed blade 53, due to the excessive pressure on both sides of the carbon fiber cloth, the movable blade 52 applies force downward to shear the carbon fiber cloth.

[0050] When the movable blade 52 falls, the fixed blade 53 and the movable blade 52 are misaligned. After falling, there is no gap between the movable blade 52 and the fixed blade 53 and both blades are in the blade groove 411 .

[0051] Furthermore, one end of the rotating block 51 away from the rotating shaft 54 ​​is connected to a knife handle 6. During the shearing process, it is often necessary to hold one side of the rotating block 51 for operation, and the setting of the knife handle 6 is convenient for the operator to hold.

[0052] Furthermore, the handle 6 is provided with a non-slip cushion 61. This cushion 61 enhances the comfort of the handle 6, preventing slipping during use while facilitating grip and operation. Furthermore, the connection between the handle 6 and the movable blade 52 is sufficiently strong and stable to withstand the forces involved in cutting. This design allows the user to easily and accurately control the cutting force and angle, improving cutting efficiency and quality.

[0053] Furthermore, a guide roller 7 is rotatably provided on the support frame 2 , and the guide roller 7 is located between the support block 41 and the placement roller 3 .

[0054] In this embodiment, the guide roller 7 is used to guide the carbon fiber cloth and keep the carbon fiber cloth in a tensioned state so as to facilitate the workers to directional pull the carbon fiber cloth to the shearing step.

[0055] Furthermore, the guide roller 7 is coated with a sponge layer 71, which is used to apply primer or water. Specifically, the sponge layer 71 has an adsorption effect. After the carbon fiber cloth passes through the bottom of the guide roller 7, it is extended for the next step of fixation and shearing. As it passes through the guide groove, the water or primer on the sponge layer 71 soaks into the carbon fiber cloth.

[0056] During cleaning, that is, when there is a lot of dust on the carbon fiber cloth, water can be added to clean the carbon fiber cloth on the sponge layer 71. At this time, the workbench 1 can be used as a cleaning platform.

[0057] During shearing, since the carbon fiber cloth will need to be coated with primer during subsequent use and installation, adding primer to the sponge layer 71 and applying it to the carbon fiber cloth in a guided manner saves the need to apply primer to the carbon fiber cloth later, thereby improving the work efficiency of the staff. In addition, the viscosity provided by the primer keeps the carbon fiber cloth in a taut state, facilitating the subsequent shearing work.

[0058] Furthermore, a lifting structure 8 is provided between the support block 41 and the workbench 1 .

[0059] In actual use, due to the different heights of operators, the height of the shearing assembly 5 needs to be adjusted for easy operation. However, the lifting structure 8 can drive the support block 41 to rise and fall. In this embodiment, the lifting structure 8 can be an electric telescopic rod, which starts the extension or contraction of the electric telescopic rod to drive the support block 41 to rise or fall.

[0060] In addition, the lifting structure 8 can also be a threaded sleeve combination. Specifically, the lifting structure 8 includes a threaded sleeve and a threaded rod. The threaded sleeve is rotatably set on the workbench 1. A knob at the bottom of the workbench 1 is set at one end of the threaded sleeve. The threaded sleeve is threadedly connected to the threaded rod. One end of the threaded rod is fixedly connected to the support block 41. The knob is turned to drive the threaded sleeve to rotate. Under the threaded connection between the threaded sleeve and the threaded rod, the threaded rod moves up or down to drive the movement of the support block 41, thereby finally achieving lifting.

[0061] The lifting structure 8 is not limited to the above two forms, and any other structure that can adjust the height of the support block 41 can be used as the lifting structure 8.

[0062] Example 2

[0063] According to another embodiment of the present invention, Figure 1 As shown, a counterweight water tank 9 is also included, and the counterweight water tank 9 is arranged at one end of the workbench 1 close to the placement roller 3.

[0064] In this embodiment, the counterweight water tank 9 is a square structure and is located on the right side of the workbench 1. During the carbon fiber cloth cutting process, since the movable blade 52 is located on the left side of the workbench 1, manual force is required during cutting. In order to ensure the balance of the workbench 1, a counterweight water tank 9 is set on the right side of the workbench 1 to ensure the stability and balance of the workbench 1.

[0065] Furthermore, a water inlet 91 is provided on the top of the counterweight water tank 9, and a water outlet 92 is provided on one side of the counterweight water tank 9. The counterweight water tank 9 contains water to increase or reduce the weight of the counterweight water tank 9. At the same time, the water in the counterweight water tank 9 can be used for cleaning the countertop, etc., and can also be used to add water to the sponge layer 71.

[0066] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model.
