Technical Field

[0001] This utility model relates to the field of leather cutting technology, and in particular to a high-efficiency cutting device for bag processing. Background Technology

[0002] In the past, leather cutting for bags mainly relied on manual operations. Skilled workers used simple tools such as scissors and knives, and cut according to experience and templates. However, this method has many shortcomings. On the one hand, it is difficult to guarantee the accuracy of manual cutting, and size deviations are prone to occur, especially for complex shapes and curves, which are difficult to make completely consistent. This will affect the quality and appearance of the finished bags. On the other hand, manual cutting is inefficient and requires a lot of manpower and time, which cannot meet the needs of large-scale production. Moreover, manual cutting makes it difficult to optimize the layout of leather, resulting in serious waste of leather materials and increasing production costs.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1, as Figure 1 , Figure 2 As shown, a high-efficiency cutting device for bag processing includes a support 1, a moving mechanism 2 rotatably connected to the middle of the support 1, a motor 3 fixedly connected to the rear end of the moving mechanism 2, a collecting mechanism 4 rotatably connected to the left side of the support 1, a fixed plate 5 fixedly connected to the left side inside the support 1, a strip plate 6 fixedly connected to the middle of the upper end of the fixed plate 5, two fixed mechanisms 7 fixedly connected to the upper part of the moving mechanism 2, and a supporting mechanism 8 installed in the middle of the inner cavity of the support 1.

[0027] During implementation, motor 3 is started, which drives the moving mechanism 2 to operate. The moving mechanism 2 drives the collecting mechanism 4, the fixing mechanism 7, and the supporting mechanism 8 to operate. At this time, the staff puts the leather to be cut into the supporting mechanism 8. The supporting mechanism 8 drives the leather to move to the left. When it gets close to the cutting tool, the fixing mechanism 7 applies pressure to the leather and drives the leather to move to the left. The cut leather is divided into two sides by the strip 6 and is rolled up by the collecting mechanism 4 after passing through the fixing plate 5.

[0028] For instructions on cutting leather, please refer to [link / reference]. Figure 3 The moving mechanism 2 includes a fixed rod 27. The rear end of the fixed rod 27 is fixedly connected to the output end of the motor 3. A blade 28 is fixedly connected to the middle of the fixed rod 27. A gear 1 21 is fixedly connected to the rear of the fixed rod 27. A gear 22 meshes with the lower right corner of the gear 1 21. A roller 23 is fixedly connected to the shaft of the gear 22. A gear 3 24 is fixedly connected to the front end of the roller 1 23. A gear 4 25 meshes with the upper part of the gear 3 24. A connecting rod 26 is fixedly connected to the rear end of the gear 4 25.

[0029] During implementation, motor 3 drives fixed rod 27 to rotate clockwise, fixed rod 27 drives gear 1 21 to rotate clockwise, gear 1 21 drives gear 2 22 to rotate counterclockwise, gear 2 22 drives roller 1 23 and gear 3 24 to rotate in the same direction, roller 1 23 drives transmission belt 81 to rotate counterclockwise, causing the leather to move to the left, gear 3 24 drives gear 4 25 to rotate clockwise, gear 4 25 drives connecting rod 1 26 to rotate, and fixed rod 27 drives blade 28 to rotate to cut the leather;

[0030] For further details, please refer to [link / reference]. Figure 4The supporting mechanism 8 includes roller 2 82, roller 4 84, roller 5 85 and roller 6 86. The front and rear ends of roller 2 82 are rotatably connected to the support 1. Two transmission belts 81 are wound around the outer surface of roller 2 82. The ends of the two transmission belts 81 away from roller 2 82 are covered by roller 3 83. The front and rear ends of roller 4 84 are rotatably connected to the support 1. The front and rear ends of roller 5 85 are rotatably connected to the support 1. Roller 4 84 and roller 5 85 are located above the two transmission belts 81. The front and rear ends of roller 6 86 are rotatably connected to the support 1.

[0031] Roller 2 82 and roller 3 83 have the same diameter as roller 1 23. Roller 6 86 is located inside the two transmission belts 81 and contacts the upper part of the transmission belts 81. Roller 6 86 is located directly below the fixing mechanism 7.

[0032] During implementation, roller 1 23 drives two transmission belts 81 to rotate counterclockwise. Since roller 2 82 and roller 3 83 are rotatably connected to the bracket 1, under the action of friction between the transmission belts 81 and roller 2 82 and roller 3 83, the transmission belts 81 drive roller 2 82 and roller 3 83 to rotate counterclockwise. The diameters of roller 2 82 and roller 3 83 are the same as those of roller 1 23, and together they support the two transmission belts 81, allowing the leather to move horizontally to the left above the two transmission belts 81. Rollers 4 84 and roller 5 85 limit the movement of the leather without affecting its movement. Roller 6 86 cooperates with the fixing mechanism 7, so that when the fixing mechanism 7 applies pressure to the leather, it supports the two transmission belts 81, preventing the two transmission belts 81 from deforming and affecting the leather cutting. The transmission belts 81 are divided into front and rear parts. In order to allow the blade 28 to rotate in the middle of the transmission belts 81, so that the axis of the blade 28 faces the leather plane, the blade 28 can reduce the leather from lifting or folding downwards when it acts on the leather.

[0033] To secure the leather and prevent cutting errors and material waste, please refer to... Figure 5 The fixing mechanism 7 includes four telescopic sleeves 71, which are arranged in a ring around the axis of the connecting rod 26. The ends of the four telescopic sleeves 71 near the connecting rod 26 are fixedly connected to the connecting rod 26. Each of the four telescopic sleeves 71 is slidably connected to a telescopic rod 72. An arc-shaped plate 74 is fixedly connected to the end of the telescopic rod 72 away from the connecting rod 26. A spring 73 is sleeved on the outer surface of the telescopic sleeves 71. The ends of the telescopic sleeves 71 near the connecting rod 26 are fixedly connected to the connecting rod 26, and the ends of the telescopic sleeves 71 away from the connecting rod 26 are fixedly connected to the arc-shaped plate 74.

[0034] The end of the arc-shaped plate 74 away from the connecting rod 26 is in contact with both transmission belts 81;

[0035] During implementation, connecting rod 26 drives telescopic sleeve 71, telescopic sleeve 71 drives telescopic rod 72 to rotate, telescopic rod 72 drives arc plate 74 to rotate. When the lower end of arc plate 74 contacts the leather surface, telescopic rod 72 is compressed. Under the combined action of the upward support force of transmission belt 81 on the leather and the reaction force generated by the compression of telescopic rod 72, the leather is fixed, so that the leather will not shift when the blade 28 cuts the leather, and the position of the leather to be cut is directly opposite the blade 28, so that the cutting is more complete and the material waste caused by cutting errors is reduced.

[0036] Example 2: To collect the cut leather, refer to... Figure 6 The collecting mechanism 4 includes two pulleys 41, which are rotatably connected to the roller 23. A transmission belt 42 is wound around the outer surface of the pulley 41. The end of the transmission belt 42 away from the pulley 41 is covered by a pulley 43. A connecting rod 45 is fixedly connected to the inner surface of the two pulleys 43. An annular baffle 46 is fixedly connected to the middle of the connecting rod 45. Support plates 44 are rotatably connected to both ends of the connecting rod 45.

[0037] During implementation, pulley 41 drives transmission belt 42, transmission belt 42 drives pulley 43 to rotate, and pulley 43 drives connecting rod 45 to rotate, thus rolling up and collecting the cut leather.

[0038] It should be noted that the specific installation method, circuit connection method, and control method of the motor 3 used in this utility model are all conventional designs, and will not be described in detail in this utility model.
