[0023] See Figure 1A circular blade leather cutting machine for making flat sneakers is shown, comprising a machine body 1, a motor 2 fixedly mounted on the machine body 1, and a rotating shaft mounted on the motor 2. A bearing is fitted between the rotating shaft and the machine body 1. A circular blade 3 is mounted on the rotating shaft. The outer surface of the circular blade 3 is rough. A groove 101 is provided at the top of the machine body 1, and a portion of the circular blade 3 protrudes from the groove 101. An edge-adjusting device 4 is provided at the top of the machine body 1. The leather to be trimmed moves along the edge-adjusting device 4, which is located at the rear of the groove 101. A pressing device 5 is slidably fitted through the edge-adjusting device 4, located in front of the groove 101. A pressing device 6 is mounted on the machine body 1, directly facing the circular blade 3. The leather to be trimmed passes through the bottom of the pressing device 6.

[0024] In the above technical solution, the motor 2 drives the circular blade 3 to rotate at high speed, and the outer surface of the circumference 3 is used to peel the leather. The edge-adjusting device 4 makes the leather edge-adjusted to ensure that the edge-cutting distance is controlled consistently. The pressing device 6 makes the edge-cutting thickness of the leather consistent. The pressing device 5 presses and feeds the leather, eliminating the need for human hand contact with the leather and avoiding hand injury from the circular blade.

[0025] See Figure 1 and Figure 2 As shown, the edge-holding device 4 includes an edge-holding strip 41, which is fixed to the body 1. An air inlet groove 42 is provided on the front end of the edge-holding strip 41, corresponding to the circular blade 3. A connecting pipe 43 is provided on the side of the edge-holding strip 41, communicating with the air inlet groove 42. A suction fan 7 is installed inside the body 1, connected to an air inlet pipe 71. A first connecting pipe 72 is fitted between the air inlet pipe 71 and the connecting pipe 43. A metal filter cup 73 is provided at the air outlet of the suction fan 7, with filter holes evenly distributed on its surface. The size of the filter holes is 40-120 micrometers. A guide rod 44 is provided at the top of the edge-holding strip 41, guiding the pressing device 6 through the guide rod 44. A first guide rod 45 is provided at the end of the edge-holding strip 41 away from the connecting pipe 43, guiding the pressing device 5 through the first guide rod 45.

[0026] In the above technical solution, by attaching the edge strip 41 to the leather, the fine powder generated during the peeling of the leather can be adsorbed by the negative pressure generated by the suction fan 7, so that there are fewer particles in the production process, ensuring safe production and reducing the risk of inhalation.

[0027] See Figure 2 and Figure 3As shown, the pressing device 6 includes a pressing rod 61, a slider 62 at the rear end of the pressing rod 61, a pressing knife 63 at the front end of the pressing rod 61, a feeding surface 64 at the lower end of the pressing knife 63, the feeding surface 64 being inclined towards the direction of material movement, a guide hole 65 on the rod body of the pressing rod 61, a guide rod 44 passing vertically through the guide hole 65, a housing 66 at the top of the machine body 1, a screw 67 vertically arranged inside the housing 66, the screw 67 rotatably engaging with the housing 66, a knob 68 at the upper end of the screw 67, and a threaded hole 69 for engaging with the screw 67.

[0028] In the above technical solution, the thickness through which the leather can pass is limited by the downward pressure of the pressing knife 63, and the peeling work is completed by the round knife 3 while the leather is being pulled along the edge strip.

[0029] By rotating the screw 67, the downward pressing position of the pressure knife 63 is adjusted, thereby adjusting the thickness of the peel.

[0030] See Figure 2 As shown, a limiting plate 4441 is provided on the guide rod 44, and the limiting plate 4441 limits the downward movement of the pressing rod 61.

[0031] The setting of the limiting plate 4441 can limit the downward movement distance of the pressing rod 61 and prevent the lower end of the pressing knife 63 from contacting the circular knife 3.

[0032] See Figure 2 As shown, the pressing device 5 includes a sliding sleeve 51 and a rotating seat 52 disposed on the outer wall of the sliding sleeve 51. A rotating plate 53 is fitted through the rotating seat 52. A pin 54 is disposed between the rotating plate 53 and the rotating seat 52. A torsion spring is sleeved on the pin 54. Under the action of the torsion spring, the end of the rotating plate 53 away from the rotating seat 52 rotates downward. A pressing plate 55 is disposed at the end of the rotating plate 53. A smooth plate 121 is embedded at the top of the machine body 1 at the position corresponding to the pressing plate 55. The upper surface of the smooth plate 121 is smooth, and the lower surface of the pressing plate 55 is rough. An operating handle 56 is disposed at the top of the rotating plate 53. The sliding sleeve 51 is sleeved on the first guide rod 45. A guide groove 451 is axially disposed on the rod body of the first guide rod 45. A guide block 551 that cooperates with the guide groove 451 is disposed on the inner wall of the sliding sleeve 51.

[0033] In the above technical solution, the operator operates the operating handle 56 to rotate the pressing plate 55, causing the pressing plate 55 to detach from the polished plate 121. When the leather is placed on the left side of the polished plate, the pressing plate 55 presses down on the leather. Under the action of the torsion spring, the pressing plate 55 is pressed tightly. The polished plate 121 facilitates the horizontal operation of the operating handle 56 to drive the pressing plate 55 to move laterally, thereby completing the peeling of the leather.

[0034] Throughout the entire operation, the operator's hands do not approach the circular cutter, making the operation safer.
