[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This embodiment provides a leather cutting machine that facilitates adjustment of cutting size, including a platform 100. A U-shaped frame 101 is fixedly installed on the top of the platform 100. A U-shaped frame 105 is slidably connected to the inside of the U-shaped frame 101. An installation rod 102 is connected to the inner cavity of the U-shaped frame 105 through an up-and-down moving part. Two sets of connecting rings 107 are provided on the surface of the installation rod 102. The bottom of the two sets of connecting rings 107 are respectively connected to a cutting blade 403 for cutting leather through a detachable part. An adjustment part is provided on the surface of the installation rod 102 to adjust the distance between the two sets of cutting blades 403 according to the required leather width. A smoothing part for smoothing the leather before cutting is provided on the left side of the U-shaped frame 101.

[0029] The adjusting component includes a square hole 300 located at the top of the mounting rod 102 and extending along its length. A bidirectional lead screw 301 is rotatably connected to the inner cavity of the square hole 300. Nut seats 302 are threaded to both ends of the bidirectional lead screw 301. The upper and lower ends of the two sets of nut seats 302 are fixedly connected to the upper and lower inner walls of the corresponding connecting ring 107. One end of the bidirectional lead screw 301 rotatably passes through the mounting rod 102. An internal hexagonal groove 303 is provided at one end of the bidirectional lead screw 301. A groove for adjusting the connecting ring 107 is provided on one side. The fixed fastener, through the setting of the adjustment component, can flexibly adjust the spacing between the two sets of cutters 403 by rotating the bidirectional lead screw 301 to drive the nut seat 302 and the connecting ring 107 according to different leather widths, so as to adapt to diverse cutting needs. At the same time, the use of the internal hexagonal groove 303 makes it easy to operate the bidirectional lead screw 301 with tools, improving adjustment efficiency. Furthermore, in conjunction with the subsequently set fastener, the connecting ring 107 can be fixed after the spacing is adjusted to prevent the spacing of the cutters 403 from changing during the cutting process, thereby improving cutting accuracy and stability.

[0030] The fasteners include limiting bolts 108 threaded to one side of each set of connecting rings 107. The ends of the two sets of limiting bolts 108 are threaded through the corresponding side connecting rings 107 and abut against the surface of the mounting rod 102 to prevent the connecting rings 107 from moving. By setting the fasteners, the limiting bolts 108 are threaded through the connecting rings 107 and abut against the surface of the mounting rod 102, which can reliably fix the position of the connecting rings 107 and effectively prevent the spacing of the cutters 403 from changing due to external forces and other factors during the cutting process, thus ensuring the dimensional accuracy and consistency of leather cutting.

[0031] The vertically movable component includes a U-shaped frame 105 that is slidably connected to the inside of the U-shaped bracket 101. Both ends of the U-shaped frame 105 are fixedly connected to the top of the corresponding side of the mounting rod 102. Limiting holes 103 are provided on both sides of the U-shaped bracket 101 along its height. Both ends of the mounting rod 102 are slidably connected to the inner cavity of the corresponding limiting holes 103. A hand-tightening bolt 104 is threadedly connected to the top of the U-shaped bracket 101. The bottom thread of the hand-tightening bolt 104 penetrates the U-shaped bracket 101 and is rotatably connected to the top of the U-shaped frame 105. By using the moving parts, rotating the hand-tightening bolt 104 controls the U-shaped frame 105 to slide up and down within the U-shaped bracket 101, thereby driving the mounting rod 102, connecting ring 107, and cutter 403 to move up and down, achieving flexible adjustment of the height of the cutter 403. At the same time, the limiting hole 103 limits and guides the mounting rod 102, ensuring the stability and accuracy of the up and down movement of the cutter 403. This allows the equipment to adapt to leathers of different thicknesses, making it easier to control the depth of the cutter 403 into the leather, and improving the applicability and processing quality of the equipment.

[0032] The detachable components include fixing blocks 406 fixedly installed on the lower part of opposite sides of the two sets of connecting rings 107. Each of the two fixing blocks 406 has a threaded hole 404 in the middle of its opposite side. Positioning rods 405 are fixedly connected to both ends of each opposite side of the two fixing blocks 406. Two sets of cutters 403 are slidably sleeved on the surface of the corresponding positioning rods 405. Positioning blocks 402 are slidably sleeved on the surface of the two positioning rods 405 on the same side. Fixing screws are inserted into the opposite sides of each of the two positioning blocks 402. Two sets of fixing bolts 400 pass through the corresponding side positioning blocks 402 and are threaded into the inner cavity of the corresponding side threaded holes 404. With the setting of detachable parts, the positioning rod 405 initially positions the cutter 403. Then, the positioning block 402 and fixing bolts 400 are used to fix the cutter 403 to the fixing block 406. At the same time, when the cutter 403 is worn or needs to be replaced with a different type of cutter 403, the operation can be carried out quickly and conveniently, improving the maintenance efficiency and practicality of the equipment and reducing maintenance costs.

[0033] The mounting rod 102 has a scale line 109 on one end of its front side. The zero point of the scale line 109 is located at the center of the mounting rod 102. The scale line 109 on the front side of the mounting rod 102 can intuitively display the distance between the two sets of cutters 403, providing a clear reference for adjusting the distance between the cutters 403. Without the need for additional measuring tools, the operator can quickly and accurately adjust the distance between the cutters 403 to the required position, improving adjustment efficiency and cutting accuracy.

[0034] The smoothing component includes two sets of fixing sleeves 203. One side of each fixing sleeve 203 is fixedly connected to the corresponding end of the U-shaped frame 105. A connecting rod 202 is slidably inserted into the inner cavity of each fixing sleeve 203. A connecting plate 205 is fixedly connected to the bottom of each connecting rod 202. A bearing 206 is fixedly connected to the bottom of each connecting plate 205. A pressing roller 207 is rotatably connected between the two bearings 206. A spring 204 is sleeved on the surface of the connecting rod 202 located between the connecting plate 205 and the fixing sleeve 203. A connecting plate 201 is fixedly connected to the top of the connecting rod 202, and a handle 200 is fixedly connected to the top of the connecting plate 201. Through the setting of the smoothing component, the spring 204 pushes the extrusion roller 207 to move downward and contact the leather surface, which can smooth the leather before cutting, eliminate wrinkles on the leather surface, ensure that the leather is cut in a flat state, and improve the cutting quality. At the same time, the setting of the handle 200 and the connecting plate 201 makes it easy for the operator to control the lifting and lowering of the extrusion roller 207, facilitates the insertion and adjustment of the leather, and makes the operation more convenient and efficient.

[0035] Working principle;

[0036] First, adjust the spacing between the two sets of cutters 403 according to the width of the leather. Use a tool to insert into the internal hexagonal groove 303 at one end of the double-acting screw 301 and rotate it. The rotation of the double-acting screw 301 drives the nut seat 302 connected by threads at both ends to move along the square hole 300. The nut seat 302 drives the connecting ring 107 and the cutter 403 to move synchronously. The scale line 109 on the front side of the mounting rod 102 can help observe the adjustment of the spacing between the cutters 403. After adjusting to the appropriate spacing, tighten the limiting bolt 108 on one side of the connecting ring 107 so that its thread passes through the connecting ring 107 and abuts against the surface of the mounting rod 102 to fix the position of the connecting ring 107 and prevent the spacing between the cutters 403 from changing during the cutting process.

[0037] At this point, install the cutter 403, slide the upper part of the cutter 403 onto the surface of the positioning rod 405 of the fixing block 406, then put the positioning block 402 onto the positioning rod 405, insert the fixing bolt 400 and thread it into the inner cavity of the threaded hole 404, and fix the positioning block 402 and the fixing block 406 together, thereby fixing and clamping the cutter 403.

[0038] Pull the handle 200 upward to move the extrusion roller 207 upward. Then, the end of the leather passes under the extrusion roller 207 and under the two sets of cutters 403, while connecting with the winding device. Release the handle 200, and the extrusion roller 207 moves downward under the push of the spring 204 and contacts the surface of the leather.

[0039] Subsequently, by tightening the hand-tightening bolt 104, the U-shaped frame 105 can slide up and down inside the U-shaped bracket 101. The U-shaped frame 105 drives the mounting rod 102, the connecting ring 107 and the cutter 403 to move up and down. The two ends of the mounting rod 102 slide in the limiting holes 103 on both sides of the U-shaped bracket 101, so that the cutter 403 cuts through the leather.

[0040] Start the winding equipment to wind up the leather. The leather moves under the winding tension, and the cutter 403 cuts simultaneously to complete the leather processing.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
