Detailed Implementation

[0020] 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.

[0021] Example 1: A leather cutting device for suitcases, please refer to... Figures 1-4 The system includes a support frame 1, a placement plate 2, a first motor 3, a first lead screw 4, a fixing frame 5, a second motor 6, a second lead screw 7, a cutting blade 8, and a cylinder 801. The placement plate 2 is fixedly connected to the support frame 1. The first motor 3 is bolted to the right side of the support frame 1, and the output shaft of the first motor 3 is connected to the first lead screw 4 via a coupling. The fixing frame 5 is slidably mounted on the support frame 1 and threadedly connected to the first lead screw 4. The second motor 6 is bolted to the rear side of the fixing frame 5, and the second lead screw 7 is rotatably mounted inside the fixing frame 5. The output shaft of the second motor 6 is connected to the second lead screw 7 via a coupling. The cylinder 801 is threaded onto the second lead screw 7. The telescopic rod is connected to a cutting blade 8, and a housing 9 is fixedly connected to the cutting blade 8. Two sliding frames 10 are snapped onto the housing 9. The two sliding frames 10 are slidably mounted on a flat plate 11. A first elastic element 12 is connected between the flat plate 11 and the sliding frame 10. A protective plate 20 is embedded in the sliding frame 10 to cover the first elastic element 12 and prevent foreign objects from getting tangled in it. Two protective covers 21 are provided on the support frame 1 to cover the first motor 3 and the second motor 6 and prevent them from being affected by external factors. A soft pad is embedded in the bottom of the flat plate 11 to reduce the pressure between the flat plate 11 and the leather and prevent indentations from appearing on the leather.

[0022] When leather needs to be cut, the leather is first laid on the placement plate 2. Then, the cylinder 801 and the second motor 6 are turned on to control the extension rod of the cylinder 801 to extend, causing the cutting blade 8 to move downward. The flat plate 11 moves downward and contacts the leather. The extension rod of the cylinder 801 continues to extend, and the first elastic element 12 is compressed, causing the cutting blade 8 to contact the leather and cut it. At the same time, the first elastic element 12 rebounds, causing the flat plate 11 to press the leather to prevent wrinkles from forming during the cutting process, which would affect the cutting effect and may even cause the leather to break. The output shaft of the second motor 6 rotates, driving the second lead screw 7 to rotate, causing the cutting blade 8 to move backward to cut the leather. After one cut, the first motor 3 is turned on, and the output shaft of the first motor 3 rotates, driving the first lead screw 4 to rotate, causing the fixing frame 5 to move to the right, thereby adjusting the position of the cutting blade 8.

[0023] Example 2: Based on Example 1, please refer to... Figure 3 The outer shell 9 is fixedly connected to the front and rear sides with fixing blocks 13. The fixing blocks 13 are rotatably provided with a card plate 14. The card plate 14 penetrates the outer shell 9. A second elastic element 15 is sleeved on the card plate 14. The two ends of the second elastic element 15 are respectively connected to the fixing blocks 13 and the card plate 14.

[0024] Before using the cutting device, first pull the clamping plate 14 outward, and the second elastic element 15 will be stretched accordingly. Then, the sliding frame 10 is clamped onto the outer shell 9. Then, the clamping plate 14 is released, and the second elastic element 15 rebounds, causing the clamping plate 14 to move inward and penetrate into the outer shell 9 to limit the sliding frame 10, thereby preventing the sliding frame 10 from falling off.

[0025] Please see Figure 4 The support frame 1 has guide rods 16 fixedly connected to both the front and rear sides. Two fixed plates 17 are slidably mounted on the two guide rods 16. Rubber plates 18 are slidably mounted on the fixed plates 17. A third elastic element 19 is sleeved on the rubber plate 18. The two ends of the third elastic element 19 are connected to the fixed plate 17 and the rubber plate 18 respectively.

[0026] Before laying the leather, pull the rubber plate 18 upwards, and the third elastic element 19 will be compressed accordingly. Then, lay the leather on the placement plate 2, release the rubber plate 18, and the third elastic element 19 will spring back, causing the rubber plate 18 to move downwards to press it down, thereby preventing the leather from moving to the middle during cutting.
