The application provides a clothes batch production template and a processing method thereof, and relates to the field of clothes production. The clothes batch production template and the processing method thereof comprise an upper clamping plate and a lower clamping plate, the upper clamping plate is hinged to the lower clamping plate, a module is fixedly installed in the interior of the upper clamping plate and the lower clamping plate, a plurality of marking grooves are formed in the interior of the two modules, a collar sewing groove and a fly sewing groove are formed in the interior of the two modules, and a collar guide rail and a fly guide rail are respectively formed in the upper part of the collar sewing groove and the fly sewing groove located on the upper part. The clothes batch production template and the processing method thereof are integrally manufactured by a template for producing a collar and a template for producing a fly. A positioning needle is inserted into a sponge, preliminary fixation can be performed, the operation is simple, batch production is suitable, when sewing, a roller moves along the collar guide rail, the sewing work is not only more light and easy, but also directional sewing can be performed according to the track of the collar guide rail, and the situation of deviation in the sewing process is avoided.

This invention relates to the field of paper conveying equipment technology, specifically to a paper conveying unit with convenient pressure adjustment. It includes an upper belt mounted on the upper part of the frame and a lower belt mounted on the lower part of the frame. The upper belt houses several fixed rollers, and the lower belt houses several pressure adjusting rollers. The unit also includes a lower belt power transmission chain; a roller adjusting assembly; a lower roller pneumatic tightening device; a lower roller manual tightening device; and a lower belt tightening device. In this convenient pressure-adjustable paper conveying unit, the lower belt power transmission chain drives the upper and lower belt rollers, eliminating the need for complex chain winding. Furthermore, when the upper belt moves back and forth, the upper and lower belt rollers move simultaneously without affecting the chain length, achieving simultaneous power to both the upper and lower belts. The upper belt can move freely back and forth, and the roller adjusting assembly connects all the pressure adjusting rollers to tension springs.

This utility model discloses a vibration-damping worktable for rotary machining, belonging to the technical field of rotary machining equipment. It includes a rotary motor, a supporting arm, multiple machining surfaces, and a composite vibration-damping structure. The supporting arm includes multiple cantilever arms arranged circumferentially. Each machining surface is connected to its corresponding cantilever arm via at least one composite vibration-damping structure. The composite vibration-damping structure includes a sleeve and a locking screw. The sleeve passes through and connects to the cantilever arm, while the locking screw passes through the sleeve and is threadedly connected to the machining surface. The sleeve has a hollow stepped cylindrical structure inside, including a vibration-damping groove, a through-hole, and a spring groove. The composite vibration-damping structure also includes an elastic vibration-damping head and a spring sleeved on the locking screw, respectively located within the vibration-damping groove and the spring groove. This utility model enables the machining surface to quickly reach a stable state during rapid start-up and stop of rotary machining, improving machining efficiency and accuracy.
