the leather punching machine can change boards flexibly, save time for laying materials, double the efficiency, vacuum system, clean and tidy working environment, patented product, the first in the country. mechanical punching, the leather is not black or smelly, and the self-developed numerical control system is more convenient to upgrade.
(1) back-type gantry structure
the unique fixed back type gantry structure is stable and strong, and the punch will not damage the ball screw. this excellent structural design can ensure that the equipment can be used for more than ten years. at the same time, the design also effectively reduces noise, making the working environment more comfortable.
(2) cnc precision machining
the core components of the entire equipment are all precision-machined by cnc, and the tolerance of the equipment is within ±0.02mm, ensuring that the punching precision reaches ±0.1mm.
the structural parts of the punch rod use special materials to reduce friction and minimize wear. the company has invested a lot of energy in the research of materials.
(3) high-quality pmi grinding screw
the transmission part of the machine adopts taiwan pmi grinding screw, and the precision level reaches c3 level, which effectively guarantees the precision of punching. our machines are targeted at mid-to-high-end customers, and the quality is naturally different with different positioning.
(4) low-voltage electrical component

in the process of using the jeans sewing machine to sew clothing, sometimes the speed of the clothing is not uniform, and the stitches are long and short. clothing material moves forward by the cooperation of feeding teeth and presser foot. therefore, when the above-mentioned irregular movement occurs in the clothing material, it can be concluded that the teeth and presser foot have malfunctioned or the pressure is not adjusted properly. for example, the presser foot pressure is too low. if the fabric is not pressed tightly, it will cause irregular movement. at this time, just turn the pressure adjusting screw downward to compress the clothing material. if the presser foot is too high, it will not be able to press the material, and it will also cause the material to move randomly or not at all. when adjusting, first lift the presser foot wrench, loosen the screw of the guide frame, and then move the presser foot lever from top to bottom, so that after adjusting the distance between the presser foot and the needle plate to a height of 7-8 mm, tighten the screws immediately before driving.

another reason is that the tooth screws are loose, causing the teeth to shake from side to side during operation, so that the clothing cannot move forward regularly. the solution is to remove the needle plate. tighten the two tooth screws. after tightening, install the needle plate and check whether the two sides of the teeth rub against the edge of the needle plate groove. if there
