Description

Technical Field

[0001] The present invention relates to an industrial pneumatic stapling machine, specifically a semi-automatic pneumatic stapling machine. Background Art

[0002] Most textile factories still use manual stapling machines for binding. Manual stapling machines are the most common stapling tools in major garment production factories and packaging tooling factories at present. Such manual stapling machines have high requirements for the labor intensity of workers, large labor volume, and cannot work for a long time. Even if there are suitable pneumatic stapling machines for enterprises to use, these relatively expensive pneumatic stapling machines are not very ideal. Moreover, an enterprise often needs a large number of pneumatic stapling machines for binding, so it is difficult to meet the requirements of some smaller enterprises. This also makes the workers in some small enterprises still use this manually driven stapling machine. Therefore, we need to design and develop a pneumatic automatic stapling machine that can reduce the workload of workers, improve efficiency and is convenient.

[0003] The automatic stapling machine studied in the present invention is an optimization and improvement based on the understanding of the working principle and structure of ordinary manual stapling machines. This automatic stapling machine is composed of a pneumatic switch, a cylinder, a pneumatic guide rail and an automatic label feeding device. The up and down movement of the stapler body is realized through the pneumatic guide rail; the stapling is realized through the movement of the cylinder; the automatic label feeding is realized by the cylinder driving the rack to drive the disc to rotate. All these movements are realized through the pneumatic switch, and it can be achieved that by stepping on the pneumatic switch once, the automatic stapling machine automatically realizes the whole process of threading the needle, stapling, feeding the label and resetting. In some special occasions, the stapler body can also be disassembled for manual stapling. And appropriate materials and reasonable processing techniques are used to design the automatic stapling machine. According to the designed scheme, each mechanism is reasonably combined to achieve advantages such as high efficiency and low cost. Summary of the Invention

[0004] The purpose of the present invention is to design an automatic stapling machine to solve the problems of the above-mentioned manual stapling machine, such as high requirements for the labor intensity of workers, large labor volume, inability to work for a long time and low efficiency. It can realize the whole process of automatic needle threading, stapling, label feeding and resetting of the automatic stapling machine by stepping on the pneumatic switch once. In some special occasions, the stapler body can also be disassembled for manual stapling, which reduces the cost and improves the efficiency.

There is a ratchet mechanism 23, 24 on the inner side of the paddle 21 to prevent the rubber needle strip from retreating when the marking is advanced.

[0040] The working method is as follows: first, the worker steps on the pneumatic pedal to start the connected pneumatic guide rail through control, and the pneumatic guide rail starts to work, driving the nail gun body to descend, so that the gun needle 28 passes through the product to be nailed. At the same time, as the nail gun body descends, the trigger 29 at the nail gun grip 30 touches the trigger screw 7 on the nail gun trigger block 2, triggering the movement. The micro cylinder 11 inside the nail gun starts to work, pushing the piston 13 to move. The rack of the piston 13 drives the small gear of the disc 14 to rotate clockwise, so that the disc 14 rotates clockwise. There is a protruding cylinder behind the disc 14. As the disc 14 rotates, the protruding cylinder behind the disc 14 contacts the upper end of the connecting pin 17. Due to the slope at the upper end of the connecting pin 17, a horizontal inward force is generated, and the compression spring 18 is compressed by the force, so that the cylinder behind the disc 14 can pass through. After the contact is disengaged, the connecting pin 17 is ejected again by the elastic force of the compression spring 18. At the same time, the disc 14 drives the connecting rod 15 and the nail needle 16 to move, and the nail needle 16 pushes the glue needle 27 out to complete the nailing.

[0041] When the piston 13 moves back, the disc 14 reverses, and the protruding cylinder behind the disc 14 contacts the pin 17 from the lower end, the connecting pin 17 drives the slide bar 19 to move upward, and the slide bar 19 drives the connecting rod 20 to move, thereby pushing the paddle 21 to move, and prying the rubber needle strip 26, thereby completing the automatic labeling. When the protruding cylinder behind the disc 14 loses contact with the pin 17 from the lower end, the paddle 21 is subjected to the force of the tension spring 22 and returns to its position clockwise, and the piston 13 can return to its initial position to prepare for the next labeling.

[0042] How to use: First, the worker steps on the pneumatic switch 32 to start the connected pneumatic guide rail through control. The pneumatic guide rail starts to work, driving the nail gun body to descend, so that the gun needle 28 passes through the product that needs to be nailed. At the same time, as the nail gun body descends, the trigger 29 at the nail gun grip 30 touches the screw 7 on the nail gun trigger block 2, triggering the movement. The micro cylinder 11 inside the nail gun starts to work, pushing the piston 13 to move. The piston 13 is connected to the disc 14, and the disc 14 drives the nail needle 16 to work together, and the nail needle 16 pushes the glue needle 27 out. When the piston 13 moves back, the disc 14 drives the slide bar 19 to move, and the slide bar 19 drives the connecting rod 20 to move, thereby pushing the paddle 21 to move, and paddle the glue needle strip 26, so as to complete the automatic labeling. After the labeling is completed, the spring 22 pulls the paddle 21 back to its original position. The piston is recovered, and each part is restored to prepare for the next labeling.
