A device for opening holes in a garment

Abstract

The application provides a punching device for garment processing, which comprises a base frame, a plurality of guide cylinders arranged on the base frame and driven by a first driving mechanism, a functional seat arranged at the lower end of each guide cylinder, a working rod arranged in each guide cylinder, a punching head arranged at the lower end of each working rod, a receiving cavity arranged in the inner side of the functional seat and used for accommodating the punching head, a driving arm fixed to the upper end of each working rod and driven by a second driving mechanism, and a downwardly protruding pressing ring arranged at the lower end of the functional seat. The punching device drives the punching head to punch the clothing fabric by moving the working rod downward, and completes the processing of multiple hole positions at one time. Since the guide cylinder is driven to move downward by the base frame, the clothing fabric is first pressed tightly, so that the fabric can remain stable during the process of the working rod moving downward and the punching head contacting the clothing fabric, and deformation of the fabric does not occur. The punching operation is stable and reliable, and the punching precision is high.

Description

Technical Field

[0001] This invention belongs to the field of garment processing technology, and in particular relates to a hole-opening device for garment processing. Background Technology

[0002] Garment processing is a production method that primarily utilizes modern machine processing, supplemented by manual labor. The garment processing flow includes incoming material inspection, technical preparation, cutting, sewing, buttonhole and button attaching, ironing, garment inspection, packaging, warehousing, and transportation. During buttonhole and button attaching, and for special design placement, hole-making equipment is required to create openings in the garment. In existing technologies, because garment fabrics are relatively soft and lightweight, using stamping equipment to create openings causes the stamping head to pull on the fabric upon contact, affecting the opening accuracy and easily damaging the fabric, resulting in a high defect rate. Therefore, it is necessary to improve existing hole-making devices. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the deficiencies in the prior art and proposes an opening device for garment processing.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A punching device for garment processing includes a base frame with several guide cylinders spaced apart on the base frame. Each guide cylinder is vertically arranged. The base frame is driven by a first drive mechanism, which drives each guide cylinder to move synchronously in the vertical direction. A functional seat is provided at the lower end of each guide cylinder. A working rod is installed inside each guide cylinder. A punching head is provided at the lower end of each working rod. A receiving cavity for accommodating the punching head is provided inside the functional seat. The upper end of each working rod is fixed to a drive arm, which is driven by a second drive mechanism, thereby driving each working rod to move synchronously in the vertical direction. A downwardly protruding clamping ring is provided at the lower end of the functional seat.

[0006] Furthermore, a guide sleeve is provided between the working rod and the guide cylinder, with an interference fit between the guide sleeve and the guide cylinder, and a sliding fit between the working rod and the guide sleeve.

[0007] Furthermore, the clamping ring is detachably mounted on the functional seat.

[0008] Furthermore, the guide cylinders are arranged at equal intervals.

[0009] Furthermore, the clamping ring is made of rubber or nylon.

[0010] Furthermore, the lower surface of the clamping ring is coated with a rubber coating or a nylon coating.

[0011] Furthermore, the lower surface of the clamping ring is a plane.

[0012] Furthermore, the cross-section of the clamping ring has a rectangular structure.

[0013] Compared with existing technologies, the present invention has the following advantages:

[0014] The device of this invention has a reasonable structural design. By setting a guide cylinder on the base frame and inserting a working rod inside the guide cylinder, the working rod moves down to drive the punching head to make holes in the clothing fabric, completing the processing of multiple holes at one time. Since the guide cylinder moves down with the help of the base frame, it first presses the clothing fabric, so that when the working rod moves down, the fabric can always remain stable and will not be deformed when the punching head contacts the clothing fabric. The hole-making operation is stable and reliable with high hole-making accuracy. Attached Figure Description

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0025] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] A perforation device for garment processing, such as Figures 1 to 6 As shown, the system includes a base frame 1, on which a plurality of guide cylinders 2 are spaced apart. Typically, the guide cylinders are arranged at equal intervals. Each guide cylinder is vertically arranged. The base frame is driven by a first drive mechanism 3, causing each guide cylinder to move synchronously in the vertical direction. A functional seat 4 is provided at the lower end of each guide cylinder, and a working rod 5 is installed inside each guide cylinder. A stamping head 6 is provided at the lower end of the working rod, and a receiving cavity 11 for accommodating the stamping head is provided inside the functional seat.

[0029] Each working rod has its upper end fixed to a drive arm 7, which is driven by a second drive mechanism 8, thereby causing each working rod to move synchronously in the vertical direction. The lower end of the functional seat has a downwardly protruding clamping ring 9. Preferably, the lower surface of the clamping ring is flat. Furthermore, the clamping ring has a rectangular cross-section. Additionally, the clamping ring is detachably mounted to the functional seat.

[0030] In application, the base frame is driven downward by the first drive mechanism, causing the functional seat at the lower end of the guide cylinder to press against the clothing fabric. The working rod performs the drilling action only after the clothing fabric is pressed against the functional seat, which effectively ensures the quality of the drilling process. In an optional embodiment, such as... Figure 7 and Figure 8 As shown, a buffer pad 12 can be installed at the top of the guide cylinder. During the drilling operation, it can act as a collision preventer when the drive arm moves downward, effectively avoiding direct contact between the drive arm and the guide cylinder, reducing the impact and vibration during the drilling operation, and improving drilling accuracy. For example, the clamping ring is made of rubber or nylon. Alternatively, the clamping ring is made of metal, with a rubber or nylon coating applied to its lower surface.

[0031] For example, the first drive mechanism includes a vertically arranged pneumatic cylinder, electric cylinder, or hydraulic cylinder, and the second drive mechanism includes a vertically arranged pneumatic cylinder, electric cylinder, or hydraulic cylinder. To improve the stability of the fit between the working rod and the guide cylinder, in an optional embodiment, a guide sleeve 10 can be provided between the working rod and the guide cylinder. The guide sleeve and the guide cylinder are interference-fitted, and the working rod and the guide sleeve are slidingly fitted. When the first drive mechanism drives each working rod to move downwards, each working rod can simultaneously drive each punching head to perform perforation processing on the garment fabric.

[0032] In one optional embodiment, each guide cylinder can be detachably installed on the base frame, and each working rod can be detachably installed on the drive arm. Depending on the number of openings, the required number of guide cylinders can be installed on the base frame, and the required number of working rods can be installed on the functional arm corresponding to the guide cylinders, thereby adapting to different working conditions.

[0033] The device of this invention has a reasonable structural design. By setting a guide cylinder on the base frame and inserting a working rod inside the guide cylinder, the working rod moves down to drive the punching head to make holes in the clothing fabric, completing the processing of multiple holes at one time. Since the guide cylinder moves down with the help of the base frame, it first presses the clothing fabric, so that when the working rod moves down, the fabric can always remain stable and will not be deformed when the punching head contacts the clothing fabric. The hole-making operation is stable and reliable with high hole-making accuracy.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
