AI Technical Summary
Existing industrial electric flatbed sewing machines cannot be widely used in liquid ammonia workshops because the motors are not explosion-proof and the power cords are easily worn, resulting in slow sewing speeds, high labor intensity for workers, and low production efficiency.
The system uses a pneumatic pump as the driving component, which is driven by an air source to rotate. The pump is then driven by a V-belt to rotate the flat sewing machine. The angle seat valve is controlled by a foot pedal valve to achieve an explosion-proof flat sewing machine system.
It meets the explosion-proof requirements of equipment in the liquid ammonia workshop, increases sewing speed, reduces labor intensity for workers, and improves production efficiency.

Abstract
Description
Technical Field
[0001] This utility model provides an explosion-proof flat sewing machine system for the textile printing and dyeing field, belonging to the field of textile printing and dyeing technology. Background Technology
[0002] In the textile printing and dyeing industry, some special processing procedures require explosion-proof equipment, such as in liquid ammonia workshops. Liquid ammonia is a colorless gas at room temperature and atmospheric pressure. When mixed with air, it forms an explosive mixture, which can ignite and explode upon contact with open flames or high heat. Relevant national laws and regulations require that equipment in liquid ammonia workshops meet explosion-proof requirements. Liquid ammonia production requires continuous production by sewing each fabric piece individually. Using household sewing machines for this purpose is slow and physically demanding for workers. Industrial electric flatbed sewing machines offer fast sewing speeds, but their motors are not explosion-proof, and the power cords are prone to wear and tear due to repeated use, making them unsuitable for use in liquid ammonia workshops. This patent eliminates the problems of non-explosion-proof motors and easily worn power cords in industrial electric flatbed sewing machines, thereby increasing sewing speed, improving equipment efficiency, and reducing worker fatigue. Utility Model Content
[0003] The purpose of this invention is to provide an explosion-proof flat sewing machine system for the textile printing and dyeing industry, which aims to improve workers' sewing speed, increase equipment production efficiency, and reduce workers' labor intensity. It includes a support frame, a flat sewing machine, and a power system. The flat sewing machine is mounted on the support frame, and the power system drives a pneumatic pump to rotate via an air source. The pneumatic pump then drives the flat sewing machine to perform the fabric sewing operation.
[0004] Preferably, the air source is connected to the power system after passing through a filter, a pressure reducing valve, and an oil mist lubricator in sequence.
[0005] Preferably, the air source is divided into two paths: one path enters the pneumatic pump through the angle seat valve; the other path enters the angle seat valve through the foot valve, serving as the control air for the angle seat valve to control its opening and closing.
[0006] Preferably, the pneumatic pump is connected to the flat sewing machine via a belt drive; the pneumatic pump is connected to a first pulley, and the first pulley is connected to a second pulley on the flat sewing machine via a V-belt.
[0007] Preferably, the gas outlet of the pneumatic pump is equipped with a silencer.
[0008] Preferably, the gas source is compressed air or nitrogen.
[0009] The working principle is as follows: The air source is divided into two paths. Air path one drives the pneumatic pump to rotate, which in turn drives the flat sewing machine to rotate and perform the fabric sewing work via a V-belt drive. Air path two acts as the controller air for the angle seat valve, and is controlled by a foot pedal valve installed on the air path.
[0010] Compared with the prior art, the advantages of this utility model are as follows:
[0011] The industrial flatbed sewing machine has been converted from electric to pneumatic, using a pneumatic pump as the drive component. The machine rotates via pulleys and V-belts, meeting the explosion-proof requirements of equipment in liquid ammonia workshops. This also increases the speed at which workers sew fabric ends, improves equipment efficiency, and reduces worker fatigue. A foot pedal valve on the pneumatic circuit controls the angle seat valve, ultimately enabling foot-operated control of the flatbed sewing machine and providing the same user experience as conventional flatbed sewing machines.
