[0031] In one embodiment of the present invention, Figure 1-5 As shown, an anti-collision knife device of a shoe material cutting machine is provided, including a cutting machine body 10, a movable seat 11 and a buffer mechanism. The movable seat 11 is slidably connected to the cutting machine body 10. A cutting knife assembly 12 is connected to the top of the movable seat 11, and the movable seat 11 is used to drive the cutting knife assembly 12 to move to a specified position. The buffer mechanism includes a buffer assembly 20 and a buffer base 30. The buffer assembly 20 is at least arranged as a group, and the buffer assembly 20 is arranged on one side of the cutting knife assembly 12. A pressure sensor 21 is arranged at the bottom end of the buffer assembly 20, and the pressure sensor 21 is electrically connected to the cutting knife assembly 12. The buffer base 30 is arranged in the cutting machine body 10 and is located below the cutting knife assembly 12. The buffer assembly 20 and the buffer base 30 are used to buffer the impact force of the cutting knife assembly 12 contacting the shoe upper.

[0032] In this embodiment, a conveyor belt structure for conveying the upper is provided on the cutting machine body 10, and the movable seat 11 is slidably connected to both sides of the conveyor belt structure and spans over the conveyor belt structure. A cutting station for cutting the upper is provided on the conveyor belt structure, and a buffer base 30 is located below the cutting station.

[0033] In this embodiment, the cutting knife assembly 12 includes a lifting cylinder and a cutting knife; the lifting cylinder is arranged at the center of the top of the movable seat, and the output end of the lifting cylinder is connected to the cutting knife. When cutting, the lifting cylinder extends outward, which drives the cutting knife to move to the shoe upper, cuts the shoe upper, and thus realizes the cutting of the shoe upper.

[0034] By providing a buffer mechanism, when the cutting knife assembly 12 cuts the shoe upper, the buffer assembly 20 buffers the impact force generated when the shoe upper and the cutting knife assembly 12 contact each other, thereby ensuring the stability of the cutting knife assembly 12, and the pressure between the cutting knife assembly 12 and the shoe upper is monitored by the pressure sensor 21. When the pressure value is greater than the set value, the cutting knife assembly 12 stops operating to prevent the tool on the cutting knife assembly 12 from being damaged or broken, thereby improving the service life of the cutting knife assembly 12. At the same time, by providing a buffer base 30, when the cutting knife assembly 12 contacts the buffer base 30 after cutting, the buffer base 30 further buffers the impact force generated by the cutting knife assembly 12 to prevent the tool on the cutting knife assembly 12 from being damaged or broken, and by providing the buffer base 30, the cutting knife assembly 12 is prevented from directly colliding with the inside of the cutting machine body 10, thereby avoiding damage or breakage of the cutting knife assembly 12, thereby improving the service life of the cutting knife assembly 12.

[0035] Preferably, there are two groups of buffer components 20, and the two groups of buffer components 20 are symmetrically distributed outside the cutting knife component 12. By providing two groups of buffer components 20, the cutting knife on the cutting knife component 12 is more stable, the collision between the cutting knife and the shoe surface is avoided, the cutting knife is prevented from being damaged or broken, and the service life of the cutting knife component 12 is increased.

[0036] Specifically, the buffer assembly 20 includes a first connecting plate 22, a first telescopic rod 23 and a pressing block 24. The first connecting plate 22 is arranged on one side of the cutting knife assembly 12. The first telescopic tube is arranged below the first connecting plate 22 and connected to the first connecting plate 22. The pressing block 24 is arranged at the bottom end of the first telescopic rod 23 and connected to the first telescopic rod 23. When the cutting knife on the cutting knife assembly 12 cuts the shoe upper, the pressing block 24 and the shoe upper conflict with each other to buffer the impact force on the cutting knife assembly 12 through the first telescopic rod 23, so that the cutting knife on the cutting knife assembly 12 is more stable, the cutting knife and the shoe upper are prevented from colliding with each other, the cutting knife is prevented from being damaged or broken, and the service life of the cutting knife assembly 12 is increased.

[0037] Furthermore, the first connecting plate 22 is provided with an adjustment slot 221. The adjustment slot 221 is slidably connected to one end of the first telescopic rod 23. By providing the adjustment slot 221, it is convenient to adjust the position of the first telescopic rod 23 when cutting shoe materials of different sizes, so as to adapt to the cutting of shoe materials of different sizes.

[0038] Furthermore, the first telescopic rod 23 includes an outer tube portion 231 and an inner tube portion 232. The outer tube portion 231 is disposed below the first connecting plate 22. The inner tube portion 232 is disposed inside the outer tube portion 231 and is slidably connected to the outer tube portion 231. The inner tube portion 232 is connected to the pressing block 24. A first spring 233 is provided between the outer tube portion 231 and the inner tube portion 232. When the impact force on the cutting knife assembly 12 is alleviated, the inner tube portion 232 moves upward relative to the appearance portion, and under the action of the first spring 233, the impact force on the cutting knife assembly 12 is alleviated, thereby reducing the damage to the cutting knife assembly 12 caused by the impact force, and improving the service life of the cutting knife assembly 12.

[0039] Furthermore, a threaded portion 222 extending outward is provided at one end of the outer tube portion 231 close to the first connecting plate 22, and the threaded portion 222 is located in the adjustment groove 221. A fixing cap 223 is threadedly connected to the threaded portion 222, and the fixing cap 223 is used to fix the first telescopic rod 23 to the first connecting plate 22. When adjusting the first telescopic rod 23, the fixing cap 223 is loosened, and the position of the first telescopic rod 23 is adjusted. When adjusted to a suitable position, the fixing cap 223 is tightened, so that the outer tube portion 231 of the first telescopic rod 23 is fixed to the first connecting plate 22, thereby completing the position adjustment of the first telescopic rod 23.

[0040] Furthermore, a protective layer 241 is provided at the bottom of the pressing block 24. A downwardly opening mounting groove 25 is provided between the pressing block 24 and the protective layer 241. The pressure sensor 21 is located in the mounting groove 25. By providing the protective layer 241, the upper is protected to prevent the pressing block 24 from causing damage to the upper when it collides with the upper.

[0041] Preferably, the buffer base 30 includes an anti-collision plate 31 and a bottom plate 32. The bottom plate 32 is provided on the cutting machine body 10.

A second spring 34 is sleeved on the outer side of the second telescopic rod 33, and the second spring 34 is located between the anti-collision plate 31 and the bottom plate 32. During cutting, the cutting knife on the cutting knife assembly 12 will contact the anti-collision plate 31. Under the action of the second spring 34 and the second telescopic rod 33, the buffering force on the cutting knife is relieved, avoiding direct collision between the cutting knife and the bottom plate 32, thereby improving the service life of the cutting knife assembly 12.

[0042] Furthermore, a rubber block 35 is provided in the center of the bottom plate 32. The rubber block 35 is made of rubber material, and a groove 351 opening upward is provided at the top of the rubber block 35, and the groove 351 is in a "V"-shaped structure. By providing the rubber block 35, the cutting knife on the cutting knife assembly 12 is protected to avoid direct collision between the cutting knife and the bottom plate 32, and the rubber block 35 is made of rubber material, which has a protective effect on the cutting knife and improves the service life of the cutting knife assembly 12.

[0043] Furthermore, a through hole 311 corresponding to the cutting blade assembly 12 is provided in the center of the anti-collision plate 31. A step portion 312 is provided at the top of the through hole 311. In this embodiment, the cutting tool on the cutting blade assembly 12 has a limiting portion. When the cutting blade on the cutting blade assembly 12 contacts the anti-collision plate 31, the limiting portion on the cutting blade conflicts with the step, which limits the cutting blade, prevents the cutting blade from directly colliding with the bottom plate 32, and improves the service life of the cutting blade assembly 12.
