Leather perforating device for assembly line

Abstract

The invention discloses a leather perforating device for an assembly line. The leather perforating device structurally comprises a sensor, a rotating shaft seat, a rotating shaft, a plurality of cams,a plurality of drill bits, a limit cylinder, a pressure gauge, a heating box, a thermometer, a heater, a filter device, a handle, an exhaust pipe, a drain plug, a rack, a gear, a sliding rail, a gearrow, two bases, a connecting rod, a motor, a turntable, and a transmission belt, wherein the sensor is located at one side of the transmission belt; the rotating shaft seat is arranged on the bases;the transmission belt is located between the two bases; the cams are inserted on the drill bits; and the drill bits are fixedly connected to the heating box. The heater is used for heating a heat conduction agent so as to perform heat conduction on the drill bits; after the preheating of the heater is ended, the temperatures of the plurality of drill bits are almost the same; and the drill bit specifications are the same, and the drilling depths are the same, so that the sizes and depths of holes perforated during perforating are almost the same, and the condition that when holes of differentsizes are burned by different drill bits having different temperatures, defective products are produced and a whole piece of leather is wasted, is avoided.

Description

technical field [0001] The invention is an assembly line leather punching device, which belongs to the field of punching equipment. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain. Texture and gloss, feel comfortable. [0003] However, there is a certain gap in the existing technology in the punching part of the assembly line, and it is difficult to realize fast punching on the assembly line, and the hot punching part uses a heater to directly heat the drill bit, usually using one-to-one heating, so that Although the heaters are of the same specification, there is still a relatively large error in the heating power between the two heaters due to wear or factory reasons. In this way, there are differences...

Problems solved by technology

[0003] However, there is a certain gap in the existing technology in the punching part of the assembly line, and it is difficult to realize fast punching on the assembly line, and the hot punching part uses a heater to directly heat the drill bit, usually using one-to-one heating, so that Although the heaters are of the same specification, there is still a relatively large error in the heating power between the two heaters due to wear or factory reasons. In this way, there are differences in the size of the processed leather holes. If you are lucky, you can also refurbish them. If the hole is too large, the whole piece of leather can no longer be used. Therefore, how to make heat-processed perforated leather with the same size and the same degree of ironing is a technical difficulty in the industry.
