Description

Technical Field

[0001] The utility model belongs to the technical field of clothing processing, and particularly relates to a punching device for clothing production. Background Art

[0002] Clothing is a symbol of human civilization and an essential element of human life. Besides meeting people's material needs, it also represents the culture of a certain period. The character "clothing" in ancient times had two interpretations, broad and narrow, in addition to generally referring to the clothes worn on the body. Narrowly, "clothing" specifically refers to the upper garment; broadly, "clothing" includes all things that cover the body. Ornamentation is used to enhance the beauty of people's appearance.

[0003] A punching device is used in clothing processing. When processing clothing, holes need to be punched in the fabric. The traditional punching method generally requires an operator to place the fabric on the table and press it flat by hand to keep it fixed. When multiple holes need to be punched in the fabric, manual movement of the fabric is required to achieve multiple punchings. This punching method lacks protective measures and is prone to accidentally injuring fingers when punching the fabric. Moreover, the existing punching devices lack a mechanism for positioning clothing. Due to the soft texture of clothing, the entire fabric will shift and stretch under the impact force during punching, resulting in mistakes such as punching misalignment or punching skew during processing, affecting the punching effect of clothing and causing economic losses to enterprises.

At this time, the first spring is in a compressed state, so that the lower end of the first spring squeezes the positioning pressing ring, so that the bottom of the positioning pressing ring The first spring is pressed against the outer periphery of the cloth to be punched, so that when the cloth is punched, the outer periphery of the cloth to be punched is not easy to be deviated or pulled, and the flatness of the cloth at adjacent punching positions is not easy to be affected. When the positioning pressure ring abuts against the upper surface of the cloth, the first slide column slides vertically downward along the first slide groove until the first spring is in a compressed state and cannot continue to deform, thereby achieving the positioning pressure ring abutting against the outer periphery of the cloth to be punched. Under the coordinated action of the positioning pressure ring, the first spring and the first slide column, when the cloth is punched, the outer periphery of the cloth to be punched is not easy to be deviated or pulled, and the flatness of the cloth at adjacent punching positions is not easy to be affected, thereby avoiding mistakes such as misalignment of punching or deviation of punching during processing, and achieving better punching effect.

The two cloth pressing plates 51 are driven to move vertically by starting the vertical drive assembly 6, thereby driving the punching plate 52 and the two cloth pressing plates 51 to move downward synchronously as a whole, until the four lower pressing plates 72 at the bottom of the cloth pressing plate 51 respectively abut against the four corners of the cloth, pressing the cloth as a whole onto the workbench 1. At this time, the second spring 73 is in a compressed state, so that the lower end of the second spring 73 squeezes the lower pressing plate 72, so that the bottom of the lower pressing plate 72 can be tightly pressed against the four corners of the cloth, so that when the cloth is punched, the cloth as a whole is not easily deviated or pulled, and further makes it less likely to affect the flatness of the cloth at the punching position. When the second spring 73 is in a compressed state and cannot be deformed any further, the lower pressure plate 72 is abutted against the four corners of the cloth.

[0061] The working mode of the utility model is as follows:

[0062] When in use, first place the cloth to be punched on the workbench 1, and align the position to be punched with the position of several through holes 53, then tighten the cloth and put it in a tensioned state, and then start the second motor 62 to drive the second lead screw 63 to rotate, and with the cooperation of the vertical rod 65, the second lead screw nut 64 and the cloth pressing plate 51 on the right side move vertically on the second lead screw 63 and the vertical rod 65 respectively, thereby driving the punching plate 52 and the two cloth pressing plates 51 to move downward synchronously as a whole, until the four clamping components 7 at the bottom of the cloth pressing plate 51 respectively abut against the four corners of the cloth, pressing the cloth as a whole on the workbench 1, and at the same time, several positioning pressing rings 82 under the punching plate 52 synchronously abut against the position where the cloth is to be punched, and at this time the first spring 83 is in a compressed state, so that the lower end of the first spring 83 presses the positioning pressing ring 82 The first spring 83 is pressed against the bottom of the positioning ring 82 so that the bottom of the positioning ring 82 can be tightly pressed against the periphery of the hole to be punched in the fabric, so that when the fabric is punched, the periphery of the hole to be punched position of the fabric is not easy to be deviated or pulled, and the flatness of the fabric at the adjacent hole punching position is not easy to be affected. When the positioning ring 82 abuts against the upper surface of the fabric, the first slide post 84 slides vertically downward along the first slide groove 85 until the first spring 83 is in a compressed state and cannot be further deformed, thereby achieving the positioning ring 82 abutting against the periphery of the hole to be punched in the fabric. Under the coordinated action of the positioning ring 82, the first spring 83 and the first slide post 84, when the fabric is punched, the periphery of the hole to be punched position of the fabric is not easy to be deviated or pulled, and the flatness of the fabric at the adjacent hole punching position is not easy to be affected, thereby avoiding the mistakes such as misalignment of the punching or deviation of the punching during processing.
