In this embodiment, the driving device 50 is a cylinder, and the driving device 50 drives the tool holder 60 to adjust its position up and down.

[0026] The feeding device 40 includes two support plates 41 arranged opposite to each other, a drive roller 42 mounted on the two support plates 41 by bearings, two sliders 43 slidably mounted on the two support plates 41, a driven roller 44 mounted on the two sliders 43 by bearings, a fixed frame 45 mounted on the base frame 10, a drive motor 46 mounted on the fixed frame 45, a first drive wheel 47 mounted on the drive roller 42, a second drive wheel 48 mounted on the drive motor 46, and a belt 49 connecting the first drive wheel 47 and the second drive wheel 48. The upper and lower sides of the support plates 41 are respectively mounted on the panel 21 and the base plate 23. The support plates 41 are provided with adjustment holes, through which the sliders 43 pass. The guide holes guide the sliders 43 in the vertical direction, thereby facilitating the lifting of the driven rollers 44 to allow the leather 100 to pass between the drive rollers 42 and the driven rollers 44. The drive roller 42 mounted on the support plates 41 by bearings can rotate around its axis, and the driven roller 44 mounted on the sliders 43 by bearings can rotate around its axis.

[0027] During feeding, the leather 100 to be cut passes between the drive roller 42 and the driven roller 44. The driven roller 44 presses the leather 100 onto the drive roller 42. The first drive wheel 47, the second drive wheel 48 and the belt 49 form a linkage device. The drive motor 46 drives the drive roller 42 to rotate through the linkage device. During the rotation of the drive roller 42, the leather 100 is delivered forward.

[0028] The tool holder 60 includes a linkage plate 61 and a fixing plate 62 vertically connected to the bottom of the linkage plate 61. The driving device 50 is connected to the upper surface of the linkage plate 61, and the pressing assembly 80 is installed on the linkage plate 61.

[0029] The pressing assembly 80 includes a cutting plate 81, a pressure plate 82 disposed above the cutting plate 81, an adjusting rod 83 vertically mounted on the pressure plate 82, a spring 84 sleeved on the adjusting rod 83, a washer 85, and a locking nut 86 passing through the washer 85 and mounted on the adjusting rod 83. The bottom surface of the pressure plate 82 and the upper end surface of the cutting plate 81 are both planar. The front side of the pressure plate 82 is flush with the front side of the cutting plate 81. The adjusting rod 83 passes through the linkage plate 61. The two ends of the spring 84 abut against the upper end surface of the pressure plate 82 and the lower end surface of the linkage plate 61 in the vertical direction, respectively. The washer 85 is sandwiched between the locking nut 86 and the linkage plate 61, and the washer 85 limits the locking nut 86.

[0030] The fixed plate 62 has a blade groove 621 at the bottom of its rear side. The cutter 70 is installed in the blade groove 621. The blade body of the cutter 70 has a contact surface 71 at the rear position, and the contact surface 71 is planar. During assembly, the pressure plate 82 is placed between the cutter 70 and the driven roller 44. The contact surface 71 of the cutter 70 is in contact with the front side of the pressure plate 82. In the initial state, the blade of the cutter 70 is located on one side of the pressure plate 82.

[0031] During cutting, the leather 100 passes between the cutting plate 81 and the pressure plate 82. The driving device 50 drives the knife holder 60 to press down. During the pressing process, the pressure plate 82 first presses the leather 100 tightly onto the cutting plate 81. During the further pressing process, the pressure plate 82 compresses the spring 84 to elastically contract. The adjusting rod 83 further passes upward through the linkage plate 61 of the knife holder 60 to avoid it. The cutting blade 70 is adjusted downward close to the pressure plate 82 and cuts the leather 100.

[0032] In addition, this utility model also includes a plurality of guide rods 92 and a plurality of bushings 91, wherein the guide rods 92 and bushings 91 correspond one to one. The guide rods 92 are vertically installed on the upper end face of the linkage plate 61, and the bushings 91 are installed on the upper end face of the panel 21. The guide rods 92 pass through both the panel 21 and the bushings 91. The bushings 91 guide the tool holder 60 through the guide rods 92 to prevent the tool holder 60 from deviating during operation.

[0033] The beneficial effects of this leather cutting device are as follows: By setting up a blade holder 60, a cutting blade 70, and a pressing assembly 80, the cutting blade 70 and the pressing assembly 80 are mounted on the blade holder 60, and the pressing assembly 80 is provided with a cutting plate 81 and a pressing plate 82. During cutting, the driving device 50 drives the blade holder 60 to press down, so that the cutting plate 81 and the pressing plate 82 first press the leather 100. When the driving device 50 drives the blade holder 60 to press down further, the cutting blade 70 is adjusted downward close to the pressing plate 82 and cuts the leather 100. This invention effectively prevents the leather 100 from deforming at the cut position during the cutting process, ensures the integrity of the cut, and improves the cutting quality.
