DETAILED DESCRIPTION

[0023] The application will be further described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the application discloses a cloth punching device.

[0025] With reference to Figure 1 , Figure 2 , the cloth punching device comprises a base 1, a lifting seat 2 is arranged on the base 1 in a vertical direction, a switching wheel 3 is rotationally arranged at the bottom of the lifting seat 2, and the rotating shaft of the switching wheel 3 is arranged in a horizontal direction. A plurality of hole openers 4 are threadedly connected to the outer circumferential surface of the switching wheel 3 and are arranged in a circumferential direction at uniform intervals, and the blade diameters of the hole openers 4 are different. A fixing mechanism 5 for fixing the switching wheel 3 is further arranged on the lifting seat 2.

[0026] As shown in Figure 3 , Figure 4 , a fixing rod 20 coaxial with the rotating shaft of the switching wheel 3 is fixedly arranged on the lifting seat 2, and the fixing mechanism 5 comprises a disc 52 movably arranged outside the fixing rod 20, the disc 52 is coaxial with the fixing rod 20, and the disc 52 is slidably arranged on the fixing rod 20 in the length direction of the fixing rod 20. A plurality of latch posts 50 are fixedly installed on the side wall of the disc 52 facing the switching wheel 3, and the latch posts 50 are circumferentially and uniformly arranged on the disc 52 in sequence. The latch posts 50 are parallel to the fixing rod 20, and part of the latch posts 50 are movably arranged on the lifting seat 2 in the length direction of the fixing rod 20. A plurality of latch holes 30 for inserting the latch posts 50 into the switching wheel 3 are arranged on the switching wheel 3, and the latch holes 30 correspond to the latch posts 50 one by one.

[0027] As Figure 3 , Figure 4 shown, the fixing mechanism 5 further comprises a force spring 51, the force spring 51 is sleeved outside the fixing rod 20, and the force spring 51 is telescopic along the sliding direction of the disc 52 outside the fixing rod 20. One end of the force spring 51 is in contact with the outer side wall of the disc 52 away from the switching wheel 3, and the other end of the force spring 51 is in contact with the fixing rod 20. The force spring 51 is used to push the disc 52 to be pressed on the outer side wall of the lifting seat 2 in the direction close to the switching wheel 3. The plug-in post 50 is tightly inserted into the respective plug-in hole 30 under the action of the force spring 51.

[0028] As Figure 2 , Figure 3 and Figure 4 shown, the disc 52 is integrally formed with a hollow protective cover 53 on the side wall away from the switching wheel 3, the protective cover 53 is movably arranged outside the fixing rod 20, and the force spring 51 is arranged in the protective cover 53. The force spring 51 is covered by the protective cover 53, so that the adverse effects of dust and impurities on the force spring 51 can be effectively reduced, and the service life of the force spring 51 is prolonged.

[0029] As Figure 2 shown, the disc 52 is further fixedly installed with a pulling piece 54, the protective cover 53 is arranged inside the pulling piece 54, and a gap slot 55 for hand insertion is formed between the pulling piece 54 and the protective cover 53. The pulling piece 54 facilitates the staff to pull the disc 52.

[0030] As Figure 2 , Figure 3 shown, the outer side wall of the lifting seat 2 away from the disc 52 is further provided with a positioning rod 6, the positioning rod 6 is movably arranged outside the lifting seat 2 along the lifting direction of the lifting seat 2. The length of the positioning rod 6 is arranged along the lifting direction of the lifting seat 2, and the bottom of the positioning rod 6 is rotatably provided with a pressing plate 60, which can be rotated relative to the positioning rod 6 in the horizontal direction. The pressing plate 60 is provided with a positioning hole 61 located directly below the switching wheel 3, and the positioning hole 61 can be smoothly penetrated by the hole opener 4. The positioning rod 6 is movably arranged outside the positioning spring 62, and the positioning spring 62 is telescopic along the lifting direction of the positioning rod 6 on the lifting seat 2. The upper end of the positioning spring 62 is in contact with the outer side wall of the lifting seat 2, and the lower end of the positioning spring 62 is in contact with the positioning rod 6. The positioning spring 62 is used to push the pressing plate 60 downward.

[0031] As Figure 2 , Figure 5As shown, the base 1 is also provided with a placement plate 7 located below the switching wheel 3. The placement plate 7 is used to place the fabric to be punched. The placement plate 7 is slidably disposed on the base 1 in the horizontal direction. A limiting plate 71 is fixedly provided at the bottom of the placement plate 7. The limiting plate 71 is limited within the base 1 and is slidably disposed on the base 1 in the horizontal direction.

[0032] like Figure 1 , Figure 2 As shown, multiple elastic pressure plates 70 are fixedly installed on the upper surface of the placement plate 7. The elastic pressure plates 70 are arranged sequentially at intervals along the sliding direction of the placement plate 7, and are used to press the fabric firmly against the upper surface of the placement plate 7. By pressing the fabric against the upper surface of the placement plate 7 through the elastic pressure plates 70, the stability of the fabric during punching is ensured by the limiting effect of the elastic pressure plates 70, making it less likely for the fabric to shift. In addition, when multiple holes need to be punched along a straight line on the fabric, the accuracy of the punching position can be ensured by translating the placement plate 7.

[0033] The implementation principle is as follows: When the hole opener 4 needs to be replaced, the disc 52 is first moved away from the switching wheel 3 along the fixing rod 20. At this time, the force spring 51 will be gradually compressed, and the pin 50 will gradually disengage from its respective pin hole 30 along with the disc 52. When the pin 50 is completely removed from the pin hole 30, the switching wheel 3 can be rotated. After the required hole opener 4 is rotated to the designated position, the switching wheel 3 is fixed again by the fixing mechanism 5. At this time, the switching of the hole opener 4 is completed. The entire switching process does not require disassembling the hole opener 4. The switching is convenient and quick, and effectively solves the problem that the hole opener 4 is easily lost during the replacement process.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
