Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing technology, specifically a punching device for garment manufacturing. Background Technology

[0002] In the garment manufacturing industry, fabrics need to go through multiple processes before they can be sold on the market. The use of fabrics includes spreading and cutting, especially for square fabrics, which are cut into square strips. The processing of square fabrics has evolved from the initial purely manual process to the widely used automated processing today. In the garment production process, it is often necessary to sand or punch small holes in the garments. This process requires the use of a hole punch. Hole punches are a type of instrument that is widely used in the field of mechanical processing. Many textile products require punching, and the development of hole punches in the textile industry has been very rapid. Hole punches are usually connected to punching needles, which are usually hollow. During the punching process, the hollow punching needles allow the material around the fabric to have some room to stretch, thereby reducing excessive deformation of the material caused by punching. For example, when punching some fabrics with good elasticity, the hollow punching needles can better maintain the original shape and elasticity of the fabric.

[0003] However, during use, the punching process can pierce through the fabric, producing fabric debris. Some of this debris can get inside the punching needle, resulting in poor punching performance. Additionally, when placing the fabric on the punching table, the user cannot clearly align the area to be punched with the punching needle, thus affecting the accuracy of the punching. Utility Model Content

It solves the problem that punching will penetrate the punching area of ​​the garment fabric, resulting in some fabric debris. Some of the fabric debris can easily enter the inside of the punching needle, resulting in poor punching effect. At the same time, when the user places the fabric on the punching table, it is not possible to clearly align the area to be punched with the punching needle, thus affecting the accuracy of punching.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching device for garment manufacturing, comprising a punching frame, a cylinder, a punching needle, and a clearance hole. The bottom of the cylinder is fixedly connected to the top of the punching frame. The clearance hole is opened at the bottom of the inner wall of the punching frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model incorporates an airbag. When the punching needle completes punching and resets, the airbag is compressed, forcing the air inside the airbag into the punching needle and expelling fabric debris present during punching. This solves the problem of punching through the fabric at the punching point, generating fabric debris that can easily enter the punching needle, resulting in poor punching performance. Furthermore, it addresses the issue of users not being able to clearly align the area to be punched with the punching needle when placing the fabric on the punching table, thus affecting punching accuracy. This invention achieves a self-cleaning effect and clearly shows the punched area.

[0014] 2.

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.

[0022] like Figures 1 to 4 As shown, the present invention provides a punching device for garment manufacturing, including a punching frame 1, a cylinder 2, a punching needle 3, and a clearance hole 4. The bottom of the cylinder 2 is fixedly connected to the top of the punching frame 1. The clearance hole 4 is opened at the bottom of the inner wall of the punching frame 1. The top of the punching needle 3 is connected to a transmission plate 5. The top of the transmission plate 5 is fixedly connected to an air bag 6. The top of the air bag 6 is fixedly connected to the top of the inner wall of the punching frame 1. The piston end of the cylinder 2 passes through to the inner side of the punching frame 1 and is fixedly connected to the top of the transmission plate 5. The top of the transmission plate 5 is connected to a perforated cover 7. The top of the perforated cover 7 is fixedly connected to the piston end of the cylinder 2. The air bag 6 is sleeved on the surface of the piston end of the cylinder 2. A clear indication component 8 is provided at the bottom of the punching frame 1. An auxiliary air intake mechanism 9 is provided at the bottom of the transmission plate 5. A connecting component 10 is fixedly connected to the top of the punching needle 3.

[0023] refer to Figure 3 The clearly indicated component 8 includes a mounting plate 81, which is embedded in the bottom of the punching frame 1. A laser transmission lamp 82 is fixedly connected to the top of the mounting plate 81, and the laser transmission lamp 82 is located inside the punching frame 1.

[0024] As a technical optimization of this utility model, by setting a cleaning prompt component, when the user moves the fabric to the punching frame 1 for punching, the user can use the high-brightness laser light generated by the laser transmission lamp 82 to illuminate the fabric, so that the light shines through the fabric. At this time, the user can quickly understand whether the punching position of the fabric corresponds to the position of the punching needle 3 through the light-emitting part of the fabric.

[0025] refer to Figure 4 The auxiliary air intake mechanism 9 includes an air intake hole 91, which is located at the bottom of the transmission plate 5. There are six air intake holes 91, which are distributed in a ring at equal intervals. A sealing plate 92 is movably connected to the inside of the air intake hole 91 through a shaft pin. Limiting plates 93 are fixedly connected to both sides of the bottom inner side of the inner wall of the air intake hole 91. The top of the limiting plate 93 is movably connected to the bottom of the sealing plate 92.

[0026] As a technical optimization of this utility model, by setting an auxiliary air intake mechanism 9, during the airbag 6 deployment and air intake process, the air pressure inside the airbag 6 will be lower than the external atmospheric pressure. Then, the external gas will push open the sealing plate 92, which is limited by the limiting piece 93, and enter the interior of the airbag 6 through the air intake hole 91. During the compression of the airbag 6, the sealing plate 92 is limited by the limiting piece 93, thereby preventing the sealing plate 92 from unfolding downward and causing air leakage, which would affect the cleaning effect on the inside of the punch needle 3.

[0027] refer to Figure 2 The connecting component 10 includes an external threaded sleeve 101, the bottom of which is fixedly connected to the top of the punch 3. The inner wall of the transmission plate 5 is provided with a threaded groove 102, and the external threaded sleeve 101 is fixedly connected to the transmission plate 5 through the threaded groove 102.

[0028] As a technical optimization of this utility model, by setting the connecting component 10, when the punch 3 is damaged and needs to be replaced after long-term use, the user can rotate the punch 3, so that the punch 3 drives the external thread sleeve 101 to rotate. Then the external thread sleeve 101 will gradually loosen from the thread groove 102 until the external thread sleeve 101 disengages from the thread groove 102. At this time, the user can replace the punch 3.

[0029] refer to Figure 3 The bottom of the punching frame 1 is provided with an inlay groove 11. There are six inlay grooves 11, which are distributed in a ring at equal intervals. Rubber inlay balls 12 are inlaid inside the inlay grooves 11. The bottom of the rubber inlay balls 12 is fixedly connected to the top of the mounting plate 81.

[0030] As a technical optimization of this utility model, by setting the inlay groove 11 and the rubber inlay ball 12, when the laser transmission lamp 82 is damaged and needs to be replaced after long-term use, the user can directly pry out the mounting plate 81, so that the mounting plate 81 can take out the corresponding laser transmission lamp 82. At the same time, the rubber inlay ball 12 is separated from the inlay groove 11, which makes it convenient to install the new laser transmission lamp 82.

[0031] refer to Figure 3 A limiting ring 13 is provided inside the clearance hole 4, and the surface of the limiting ring 13 is welded to the inner wall of the clearance hole 4.

[0032] As a technical optimization of this utility model, by setting a limiting ring 13 and placing the limiting ring 13 inside the clearance hole 4, the maximum movement distance of the punch 3 inserted into the clearance hole 4 can be limited, thus preventing the punch 3 from directly impacting the laser transmission lamp 82 and causing damage to the laser transmission lamp 82. Furthermore, by welding the limiting ring 13 to the clearance hole 4, the fixing strength of the limiting ring 13 is improved, preventing the limiting ring 13 from falling off after repeated use.

[0033] refer to Figure 4 The bottom sides of the sealing plate 92 are fixedly connected with counterweights 14, which are made of stainless steel.

[0034] As a technical optimization of this utility model, by setting a counterweight 14, the sealing plate 92 can quickly return to its original position for sealing when the air intake stops, thanks to the weight of the counterweight 14 and the weight of the sealing plate 92 itself, thus improving the timeliness of sealing. At the same time, by using stainless steel as the material of the counterweight 14, the service life of the counterweight 14 is improved.

[0035] The working principle and usage process of this utility model are as follows: When a user needs to punch holes in clothing fabric, the user can place the clothing fabric on the punching frame 1, and then activate the cylinder 2. The cylinder 2 drives the transmission plate 5 downward through the perforated cover 7. Subsequently, the transmission plate 5 drives the connected punching needle 3 downward to contact and drill holes in the clothing fabric at the positions corresponding to the avoidance holes 4. During the downward movement of the transmission plate 5, the airbag 6 is deployed, filling its interior with gas. After drilling is completed, when the cylinder 2 is activated to reset the transmission plate 5 and the punching needle 3, the airbag 6 is compressed, causing the air inside the airbag 6 to flow through the perforated cover 7 and the interior of the transmission plate 5 into the punching needle 3. At this time, the airflow and the air pressure inside the airbag 6 can expel fabric debris present during punching. During the process of the airbag 6 deploying and taking in air, the air pressure inside the airbag 6 will be lower than the external atmospheric pressure, and then the external gas will be forced out through the limit. The sealing plate 92, which is limited by the plate 93, is pushed open and enters the airbag 6 through the air inlet 91. During the compression of the airbag 6, the sealing plate 92 is limited by the limiting plate 93, thereby preventing the sealing plate 92 from unfolding downward and causing air leakage, which would affect the cleaning effect on the inside of the punch needle 3. When the user moves the fabric to the punching frame 1 for punching, the user can use the high-brightness laser light generated by the laser transmission lamp 82 to shine on the fabric, so that the light shines through the fabric. At this time, the user can quickly know whether the punching position of the fabric corresponds to the position of the punch needle 3 through the light-emitting part of the fabric. When the punch needle 3 is damaged and needs to be replaced after long-term use, the user can rotate the punch needle 3, so that the punch needle 3 drives the external thread sleeve 101 to rotate. Then the external thread sleeve 101 will gradually loosen from the thread groove 102 until the external thread sleeve 101 is separated from the thread groove 102. At this time, the user can replace the punch needle 3.

[0036] In summary, this garment manufacturing punching device, by incorporating an airbag 6, compresses the airbag 6 when the punching needle 3 completes punching and resets. This forces the air inside the airbag 6 into the punching needle 3, expelling fabric debris present during punching. This solves the problem of punching through the fabric at the punching point, generating fabric debris, and preventing some of this debris from entering the punching needle 3 and resulting in poor punching performance. Additionally, it addresses the issue of users not being able to clearly align the area to be punched with the punching needle 3 when placing the fabric on the punching table, thus affecting punching accuracy.
