Description

Technical Field

[0001] The utility model relates to the technical field of briefcase manufacturing, in particular to a cutting machine which can prevent leather from wrinkling. Background Art

[0002] A briefcase, also known as a briefcase, is a narrow box-shaped bag, mainly used to store papers and other documents. The leather is generally obtained through physical and chemical processing such as depilation and tanning, and the leather has been denatured and is not easy to rot. Some briefcases are made of leather, and the leather usually needs to be cut during the processing.

[0003] For example, a leather cutting device disclosed in publication number CN218202886U drives a rotating shaft and a pressing plate to rotate through a motor, thereby pressing the leather material through the pressing plate to prevent displacement and wrinkles during the cutting process, thereby fixing the size and shape of the cut leather material for subsequent processing.

[0004] However, the pressing structure is less practical when used. The pressing structure presses the leather material through a pressing plate to prevent it from moving during the cutting process. However, the pressing plate is located on the side wall of the entire piece of leather, and the cutting knife will contact the leather at its lower end when moving downward for cutting. The pressing structure cannot press the leather under the cutting knife. In view of this, we propose a cutting machine that can prevent leather from wrinkling. Utility Model Content

[0005] The purpose of the utility model is to provide a cutting machine which can prevent leather from wrinkling, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a cutting machine capable of preventing leather from wrinkling, comprising a mounting frame, a feeding structure is arranged inside the mounting frame, a bracket is arranged at the upper end of the mounting frame, an electric push rod is fixedly installed at the upper end of the bracket, the output shaft of the electric push rod passes through the side wall of the bracket and is fixedly installed with a cutting tool holder, the side wall of the bracket is provided with a protective structure, and the protective structure comprises:

[0007] A fixing box, wherein the fixing box is fixedly mounted on the side wall of the bracket, a slide groove is provided on both sides of the inner wall of the fixing box, a slide rod is fixedly mounted on the inner wall of the slide groove, a sleeve is slidably connected to the surface of the slide rod, a return spring is provided on the surface of the slide rod, an inclined slide plate is fixedly mounted on the side wall of the sleeve, and inclined pressure plates are provided on the surfaces of the two groups of inclined slide plates;

[0014] Compared with the prior art, the utility model provides a cutting machine that can prevent leather from wrinkling, and has the following beneficial effects:

[0015] 1. The cutting machine that can avoid leather wrinkles is provided with a protective structure to prevent the leather under the cutting knife from wrinkling during cutting and affecting the use effect. When the electric push rod drives the cutting knife holder to move downward, the L-shaped pressure rod squeezes the inclined pressure plate, so that the two sets of connecting blocks drive the smoothing plate to move outward relatively, and the leather is stretched outward through the lower end of the smoothing plate, so that the leather is tighter and wrinkle-free during subsequent cutting.

[0016] 2. The cutting machine that can avoid wrinkles on leather is provided with a moving structure so as to facilitate better fitting and stretching of leathers of different thicknesses. When the smoothing plate moves toward the fixed plate, it drives the connecting rod to move, and the movement of the connecting rod drives the sliding block hinged thereto to move downward. The downward movement of the sliding block drives the pressing plate to move downward to contact the leather surface and drive it to move and stretch, thereby improving the practicality of the device.

The L-shaped pressure rod 310 moves downward to squeeze the inclined pressure plate 37. At this time, the inclined pressure plate 37 moves downward to move the two groups of inclined slide plates 36. The inclined slide plate 36 moves on the surface of the slide rod 33 through the sleeve 34 of its side wall, and the sleeve 34 compresses the reset spring 35 when moving to facilitate subsequent return. The inclined slide plate 36 moves so that the two groups of connecting blocks 38 on its side wall drive the smoothing plate 39 to move relatively outward, and the lower end of the smoothing plate 39 contacts the upper surface of the leather and stretches it outward. At this time, the cutting knife contacts the leather to complete the cutting work, so that the leather is tighter and there will be no wrinkles when cutting.

[0025] Please continue reading Figure 1-Figure 4The moving structure 4 includes a sliding groove 41 opened on one side of the caressing plate 39, and an opening 42 is opened on the other side of the caressing plate 39. The inner wall of the sliding groove 41 is slidably connected to a sliding block 43, and a support plate 44 is fixedly installed on the side wall of the sliding block 43. A moving rod 45 passes through the middle of the support plate 44, and a pressure plate 46 is provided at the lower end of the moving rod 45. An extrusion spring 47 is fixedly installed at the lower end of the support plate 44, and the lower end of the extrusion spring 47 is fixedly connected to the upper end of the pressure plate 46. The side wall of the sliding block 43 is hinged with one end of a connecting rod 48, and the other end of the connecting rod 48 is hinged to the side wall of the fixed plate 49. The side wall of the fixed plate 49 is fixedly connected to the side wall of the fixed box 31. By setting the moving The dynamic structure 4 facilitates better fitting and stretching of leathers of different thicknesses. When the smoothing plate 39 moves toward the fixed plate 49, it drives the connecting rod 48 to move. The movement of the connecting rod 48 drives the sliding block 43 hinged thereto to move downward. The sliding groove 41 and the opening 42 are in a connected state. The sliding block 43 drives the pressing plate 46 to move downward to contact the leather surface and drive it to move and stretch, thereby improving the practicality of the device. The movement of the pressing plate 46 squeezes the squeezing spring 47, so that the pressing plate 46 can press and move leathers of different thicknesses, thereby improving the practicality of the device.

[0026] During operation, the user can move and place the leather through the loading structure 2, and then the user can start the electric push rod 6 to work. The output shaft of the electric push rod 6 moves to drive the cutting tool holder 7 at its lower end to move. A cutting knife is arranged at the lower end of the cutting tool holder 7 to facilitate cutting work. During the movement of the cutting tool holder 7, the L-shaped pressure rod 310 on its side wall will also move downward. The L-shaped pressure rod 310 moves downward to squeeze the inclined pressure plate 37. At this time, the inclined pressure plate 37 moves downward to move the two groups of inclined slide plates 36. The inclined slide plate 36 moves on the surface of the slide rod 33 through the sleeve 34 on its side wall. The sleeve 34 compresses the reset spring 35 when moving, and the inclined slide plate 36 moves so that The two groups of connecting blocks 38 on the side wall drive the smoothing plate 39 to move relatively outward, and the lower end of the smoothing plate 39 contacts the upper surface of the leather and stretches it outward. When the leather is thin, the lower end of the smoothing plate 39 cannot contact the leather. At this time, when the smoothing plate 39 moves toward the fixed plate 49, it will drive the connecting rod 48 to move. The movement of the connecting rod 48 drives the sliding block 43 hinged thereto to move downward. The sliding groove 41 and the opening 42 are in a connected state. The sliding block 43 will drive the pressing plate 46 to move downward and contact the leather surface and drive it to move and stretch. The movement of the pressing plate 46 will squeeze the extrusion spring 47. At this time, the cutting knife contacts the leather to complete the cutting work, so that the leather is tighter and there will be no wrinkles when cutting.
