Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a cutting device for shoe upper materials, belonging to the technical field of shoe upper material processing. Background Technique

[0002] The shoe upper refers to the part covering the toes, the top, the sides and the back of the heel. The shoe upper is usually made of multiple parts of leather materials, generally using leather or suede, and is sewn by professional craftsmen. We do have some shoe upper styles made of a whole piece of leather, and this style is usually called a one-piece shoe upper. During the cutting process of shoe upper materials, a shoe upper material cutting machine is often used, and the shoe upper materials need to be cut into individual blocks before the next step of processing.

[0003] A cutting device for shoe upper materials disclosed in the Chinese Patent Application Publication Specification CN219894843U, through the mutual cooperation of a support frame, a slider, a cross plate, a cylinder, a first mounting plate, a cutting knife, a telescopic rod, a support plate and a groove, adjusts the position of the cutting knife when cutting the shoe upper materials through an adjusting mechanism, which is convenient for cutting the required size according to the needs of users, and is convenient for playing a buffering role during cutting, making the cutting more stable.

[0004] In the above patent solution, during cutting, an electric push rod is required to drive a pressing plate to fix both sides of the raw material. However, only fixing both sides of the raw material, the stress it receives will be concentrated on the edges, and there may not be enough support and tension between the cutting areas of the raw material. During the cutting process, the fabric is prone to looseness, stretching or movement, resulting in fabric deformation or inaccurate dimensions. Therefore, a cutting device for shoe upper materials is proposed here. Content of the Utility Model

[0006] The utility model is realized through the following technical solutions: A cutting device for shoe upper materials, including a base, a cutting table fixed on the upper surface of the base, and a U-shaped frame fixed on the upper surface of the cutting table. A cutting assembly is arranged on the U-shaped frame, and a fixing mechanism is arranged on the cutting assembly.

[0007] The cutting assembly includes an electric push rod fixed on the inner wall of the hole on the upper side of the U-shaped frame. The bottom end of the electric push rod is fixed with a fixing plate, and both sides of the fixing plate are in sliding contact with the inside of the U-shaped frame. A cutting knife is fixed on the bottom surface of the middle part of the fixing plate.

A spring is sleeved on the outer surface of the elastic telescopic rod, and the two ends of the spring are respectively fixed to one side of the two fixed blocks close to each other.

[0009] Furthermore, a cutting groove is formed on the upper surface of the cutting table, and the cutting groove is located directly below the cutting knife.

[0010] Furthermore, a sliding groove is formed on one side of the U-shaped frame. A sliding block is fixed to the side of the pressing plate close to the sliding groove, and the outer surface of the sliding block is slidably connected to the inner wall of the sliding groove.

[0011] Furthermore, a limiting rod is fixed to the upper surface of the fixing plate, and the top end of the limiting rod penetrates through the upper side of the U-shaped frame and is slidably connected to the inner wall of the hole of the U-shaped frame.

[0012] Furthermore, a first mounting plate is fixed to the upper surface of the base. An installation groove is formed on the upper side of the first mounting plate.

[0034] Before the cutting knife 303 touches the shoe upper material, the rubber block 205 on the pressing plate 204 will first touch the material to fix the material. As the fixing plate 302 moves, the fixing plate 302 and the pressing plate 204 will squeeze the first driving rod 201 and the second driving rod 203 to make them move. The movement of the first driving rod 201 and the second driving rod 203 will drive the two fixing blocks 202 to move away from each other. The movement of the fixing blocks 202 will stretch the elastic telescopic rod 206 and the spring 207 until the cutting knife 303 cuts the material, improving the fixing effect on the cutting area of the shoe upper material.

[0035] Please refer particularly to Figure 3 , a first mounting plate 8 is fixed on the upper surface of the base 1. An installation groove 9 is opened on the upper side of the first mounting plate 8. A first rotating rod 10 is arranged inside the installation groove 9.

A driven gear 19 is fixed at the end of the third rotating rod 16 penetrating through the second mounting plate 12. The driving gear 18 meshes with the driven gear 19. The middle parts of the first rotating roller 15 and the second rotating roller 17 are parallel to the upper surface of the cutting table 5.

[0038] By starting the servo motor 13, the first rotating roller 15 can be driven to rotate through the second rotating rod 14. At the same time, the driving gear 18 can also be driven to rotate. The driving gear 18 can drive the third rotating rod 16 to rotate through meshing with the driven gear 19. The third rotating rod 16 can drive the second rotating roller 17 to rotate synchronously with the first rotating roller 15.
