Description

Technical Field

[0001] This utility model relates to the field of snap fastener processing technology, specifically a pneumatic snap fastener pressing machine with adjustable spacing. Background Technology

[0002] A snap fastener pressing machine is a specialized piece of equipment used in the garment and bag industries for installing snap fasteners. It primarily achieves rapid and precise pressing of snap fastener components onto the fabric. The equipment typically consists of a frame, molds, a power system, and a control system. During operation, the male and female snap fasteners are placed in the upper and lower molds respectively. After the fabric is positioned, the power system drives the molds to close. By setting the pressure and stroke, the snap fastener components are deformed and fastened to the fabric through compression. Modern pressing machines feature high automation, accurate positioning, and fast pressing efficiency. They can adapt to different specifications of snap fasteners and fabric thicknesses, and some models even support multi-station simultaneous operation. This equipment significantly improves the efficiency and consistency of traditional manual snap fastener installation, reduces labor costs, and ensures stable product quality. It is an indispensable key piece of equipment in garment and bag production lines. However, existing snap fastener pressing machines still have some problems in use:

[0003] For example, a button pressing machine with application number 202022507694.1 has the following technical solution: It includes a lower template, with support columns fixedly connected to the four corners of the upper outer surface of the lower template. A fixing plate is fixedly connected to the upper outer surface of the support columns. A cylinder is fixedly connected to the center of the lower outer surface of the fixing plate. An upper mold is fixedly connected to the lower outer surface of the cylinder. A mold hole is formed on the upper outer surface of the lower template. A sliding groove is formed on the front outer surface of the lower template. A movable plate is slidably connected inside the sliding groove. A handle is fixedly connected to the center of the front outer surface of the movable plate. A threaded hole is formed at the center of the lower outer surface of the lower template. The internal threaded connection of the threaded hole is a collection box. However, the drilling and pressing processes of traditional equipment are independent and need to be completed in stages. First, holes are pre-drilled on the fabric by hand or with a separate drilling device, and then transferred to the pressing machine to install the snap fasteners. This process not only increases the process connection time and labor costs, but may also cause misalignment of the snap fasteners due to secondary positioning deviation. On the other hand, existing pressing machines generally lack a dynamic adjustment mechanism for the installation spacing of snap fasteners, and rely on manual replacement of molds with fixed spacing to adapt to different design requirements. When the product style changes, frequent mold changes are not only time-consuming and labor-intensive, but may also cause spacing errors due to differences in mold precision, reducing production flexibility and customer customization response capabilities.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing button pressing machine. Utility Model Content

[0006] The purpose of this invention is to provide a pneumatic snap fastener pressing machine with adjustable spacing, so as to solve the problems mentioned in the background art that punching and pressing cannot be integrated and that the spacing of snap fastener installation cannot be adjusted.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable-pitch pneumatic snap fastener pressing machine includes a work platform, a pressing machine housing fixedly mounted on the work platform, and a support column connected between the rear side of the bottom surface of the pressing machine housing and the work platform. An upper mounting seat and a lower mounting seat are rotatably connected to the outside of the support column, and a sleeve is fixedly connected between the upper and lower mounting seats, with the sleeve rotatably connected to the outside of the support column.

A limit rod is horizontally installed above the work platform, with several limit holes inside the limit rod, and fixing clamps on both sides of the limit rod. A toggle rod is installed above the limit holes, forming a lifting structure that drives the limit rod to form a horizontal moving structure.

[0009] Preferably, the punching base is located directly below the punching head, and the pressing base is located directly below the pressing head.

[0010] The punching base and punching head are aligned directly, as are the pressing base and pressing head, to ensure precise alignment of the punching and pressing positions. This prevents fabric damage or snap fastener installation failure due to misalignment and improves processing accuracy.

[0011] Preferably, pressing blocks are provided through the left and right sides of the mounting base, and connecting rods are fixedly installed at the bottom of the pressing blocks. The connecting rod on the left side of the mounting base passes through the mounting base and is connected to a punching head, and the connecting rod on the right side of the mounting base passes through the mounting base and is connected to a pressing head.

[0012] The pressing blocks on both sides of the upper seat, the connecting rod, the punching head, and the pressing head are linked together.

[0013] Preferably, mounting bases are fixedly installed on the bottom of the left and right sides of the mounting base, and springs are connected to the upper surface of the mounting bases, with the springs connected to the bottom of the pressing block.

[0014] The mounting base and spring design allow the pressing block to automatically reset after drilling or pressing, reducing manual reset operations. At the same time, the spring's buffering effect can prevent mold damage caused by excessive pressing.

[0015] Preferably, the internal groove of the pressing head is fitted with a snap fastener, and the internal groove of the pressing base is fitted with a snap fastener.

[0016] The grooves in the pressing head and pressing base are respectively installed with the snap fastener male and female. The mold limit ensures that the snap fastener components are accurately positioned, and the force is evenly distributed during pressing, which improves the installation firmness and consistency.

[0017] Preferably, a first support is provided on the left side of the working platform, and a second support is provided on the right side of the working platform, and an inclined block is provided on the left side of the second support, with a limit rod installed through the first support and the second support.

[0018] The first and second brackets work together with the inclined block to limit the rod. The inclined block can guide the edge of the fabric to align with the limit rod, and the limit hole can achieve lateral positioning of the fabric, making it easy to adjust the installation spacing of the snap fasteners.

[0019] Preferably, a crossbeam is fixedly installed on the right side of the pressing machine box, and an electric telescopic mechanism is installed above the crossbeam. A support frame is connected and installed at the lower output end of the electric telescopic mechanism, and the actuating rod is rotatably connected to the front side of the support frame through a torsion spring.

[0020] The adjustment mechanism, consisting of an electric telescopic mechanism, a support frame, and a lever, uses the electric telescopic mechanism to drive the lever to rise and fall. By engaging different limit holes, the lever can be moved laterally, thus achieving automated adjustment of the four-piece snap fastener installation spacing without the need for manual mold changing.

[0021] Compared with the prior art, the beneficial effects of this utility model are: this pneumatic four-way snap fastener pressing machine with adjustable spacing...

[0022] 1. Integrated punching and pressing operation: By installing the punching head and pressing head integrated at the bottom of the upper seat, and with the downward pressing action of the pneumatic telescopic end, the fabric punching and snap fastener pressing can be completed at the same workstation, reducing process connection time and labor costs, and avoiding secondary positioning deviation.

[0023] 2. Dynamic Spacing Adjustment and Precise Positioning: The combination of limit rods, limit holes, and electric telescopic mechanisms allows for quick adjustment of the snap fastener installation spacing according to design requirements. Precise spacing positioning is achieved by inserting the lever into different limit holes, improving the equipment's adaptability to various product styles and reducing mold change frequency.

By engaging different limiting holes 23, the limiting rod 22 can be moved laterally, realizing the automatic adjustment of the snap fastener installation spacing without the need for manual mold changing.

[0041] Working principle:

[0042] In use, the fabric is placed above the lower mounting base 5 and fixed by the fixing clips 24 on both sides of the limiting rod 22. The upper mounting base 4 and the lower mounting base 5 are rotated so that the punching head 11 is directly below the pneumatic telescopic end 3. The pneumatic telescopic machine drives the pneumatic telescopic end 3 to press down the upper mounting base 4. The left pressing block 7 drives the punching head 11 to descend via the connecting rod 8. Under the buffering action of the spring 10, the fabric is punched. After completion, the spring 10 returns to its original position and lifts the punching head 11. The electric telescopic machine 16 drives the actuating rod 18 to rise and fall and engage with the corresponding limiting hole 23 of the limiting rod 22. The limiting rod is guided by the inclined block 21. Move 22 to the left to align the fabric edge and complete the positioning; after punching, move and rotate the limit rod 22 to the right, rotate the upper mounting seat 4 and the lower mounting seat 5 so that the pressing head 12 is directly below the pneumatic telescopic end 3. The pneumatic telescopic machine drives the pneumatic telescopic end 3 to press down the pressing block 7 on the right side of the upper mounting seat 4 to push the pressing head 12 down, aligning the four-in-one fastener in the groove of the pressing head 12 with the female fastener in the groove of the pressing base 14 with the fabric hole. The pneumatic telescopic machine applies pressure to complete the pressing, and the spring 10 returns to its original position. Repeat the drive of the electric telescopic machine 16 to position the fabric for pressing the four-in-one fastener. After completion, remove the fabric.
