[0002] Safety shoes are a general term for safety shoes and protective shoes. They refer to shoes worn in different workplaces that protect the feet and legs from foreseeable injuries. Safety shoes require leather cutting during production.

[0003] The existing patent (Announcement No.: CN220859568U) discloses a safety shoe processing and leather cutting equipment, including a box body, and columns are installed at the four corners of the lower end of the box body. There are four columns. The leather is placed under the lower end of the pressure wheel, and the third drive motor is started. The third drive motor drives the pressure wheel to rotate through the coupling. The pressure wheel presses the leather to avoid wrinkles on the leather. The lamination is to ensure that the leather material is locked and does not shift, to prevent it from being cut and wasted, and to meet the leather cutting standards. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved: after the above-mentioned device flattens the leather through the pressure roller, the leather needs to be manually placed under the cutting disc for cutting, but because the safety shoe leather is produced in large quantities, this causes the staff to be more tired after working for a long time, which reduces the efficiency of cutting the safety shoe leather. Utility Model Content

[0004] In order to improve the above-mentioned problem that after the leather is flattened by a pressing roller, the leather needs to be manually placed under a cutting disc for cutting. However, since the safety shoe leather is produced in large quantities, this causes the workers to be relatively tired after working for a long time, thereby reducing the efficiency of cutting the safety shoe leather. The utility model provides a safety shoe processing and leather cutting device.

[0005] The utility model provides a safety shoe processing and leather cutting device, which adopts the following technical scheme:

[0006] A safety shoe processing and leather cutting device comprises a support seat, the top of the support seat is fixedly connected to a C-shaped bracket, the top of the C-shaped bracket is fixedly connected to a hydraulic cylinder, the bottom end of the telescopic rod of the hydraulic cylinder passes through the bottom of the horizontal plate of the C-shaped bracket and is fixedly connected to a cutting knife;

[0007] An H-shaped block is fixedly sleeved on the side of the telescopic rod of the hydraulic cylinder, and clamps are rotatably connected inside the two grooves of the H-shaped block. Tension springs are fixedly connected on opposite sides of the two clamps, and one end of the tension spring is fixedly connected to the side of the H-shaped block.

[0008] Through the above technical solution, the leather cutting process is more automated, the fatigue of workers after long hours of work is reduced, the speed of cutting safety shoe leather is increased, and the leather can be straightened, reducing the possibility of leather being skewed after cutting.

[0009] Optionally, in the above-mentioned safety shoe processing and leather cutting equipment, the splint includes a connecting plate, the side of the connecting plate is rotatably connected to the inside of the groove of the H-shaped block, the lower side of the connecting plate is fixedly connected to a C-shaped bar, the two vertical bars of the C-shaped bar are rotatably connected to a pressure roller on the opposite side, and the side of the pressure roller is fixedly connected to a rubber ring.

[0010] Through the above technical solution, the safety shoe leather to be cut can be flattened by the pressing roller.

[0011] Optionally, in the above-mentioned safety shoe processing and leather cutting equipment, a connecting strip is fixedly connected to the side of the C-shaped strip close to the cutting knife, a scraper is rotatably connected to the bottom of the connecting strip, a compression spring is fixedly connected to the top of the scraper, one end of the compression spring is fixedly connected to the top of the connecting strip, and the scraper is an acrylic strip.

[0012] Through the above technical solution, the safety shoe leather that needs to be cut can be straightened by the scraper.

[0013] Optionally, in the above-mentioned safety shoe processing and leather cutting equipment, long grooves are provided on opposite sides of the two vertical plates of the C-shaped bracket, and moving blocks are slidably connected inside the long grooves, and opposite sides of the two moving blocks are fixedly connected to two sides of the cutting knife respectively.

[0014] Through the above technical solution, the cutting knife can be moved vertically up and down through the long groove and the moving block.

[0015] Optionally, in the above-mentioned safety shoe processing and leather cutting equipment, both sides of the top of the support seat are rounded, and two trapezoidal support blocks are fixedly connected to the bottom of the support seat.

[0016] Through the above technical solution, the trapezoidal support block can increase the contact area between the bottom of the support seat and the ground.

[0017] Optionally, in the above-mentioned safety shoe processing and leather cutting equipment, the support seat is C-shaped, and the opposite sides of the two vertical plates of the C-shaped support seat are fixedly connected with inclined plates, and the side surfaces of the inclined plates are fixedly connected to the bottom of the horizontal plate of the C-shaped support seat.

[0018] Through the above technical solution, the overall stability of the C-shaped support seat can be increased by using two inclined plates to prevent the C-shaped support seat from deflecting.

[0019] Optionally, in the above-mentioned safety shoe processing and leather cutting equipment, a fixing groove is opened in the middle of the top surface of the C-shaped bracket, and the interior of the fixing groove is fixedly connected to the side surface of the hydraulic cylinder.

[0020] Through the above technical solution, the fixing groove can be used to increase the firmness of the hydraulic cylinder and reduce the vibration generated by the hydraulic cylinder when it is extended or retracted.

[0021] In summary, the present invention has at least one of the following beneficial effects:

[0022] The hydraulic cylinder drives the cutting knife to cut the leather, and at the same time, the hydraulic cylinder drives the H-shaped block, the clamping plate and the pressure roller to move downward. The downward movement of the hydraulic cylinder and the extrusion force brought to the clamping plate by the support seat make the two clamping plates drive the pressure roller to move to both sides, stretching the tension spring. When the pressure roller flattens the leather, the cutting knife moves downward to cut the flattened leather, thereby making the leather cutting process more automated, reducing the fatigue of the staff after long hours of work, and increasing the speed of cutting the safety shoe leather.

[0023] The H-shaped block, splint, C-shaped strip and pressure roller are driven downward by the hydraulic cylinder. When the pressure roller contacts the top of the support seat and the two splints open to both sides, the pressure roller flattens the leather. At the same time, the two scrapers slide on the upper side of the leather to straighten the leather, thereby reducing the possibility of the leather being skewed after cutting.
