Leather product perforating device with adjustable perforating distance

Abstract

The invention relates to the technical field of leather products, and discloses a leather product perforating device with an adjustable perforating distance. The device comprises a first motor, wherein the output end of the first motor is fixedly connected with a driving wheel; a transmission belt is movably connected to the rim of the driving wheel; an arc-shaped plate is movably connected to theend, away from the driving wheel, of the transmission belt; a telescopic rod is fixedly connected to the side, away from the transmission belt, of the arc-shaped plate; and a driving wheel is fixedlyconnected to the end, away from the arc-shaped plate, of the telescopic rod. According to the leather product perforating device with the adjustable perforating distance, an adjusting screw block isfar away from or close to the driving wheel through forward and reverse rotation of a driving screw rod, the adjusting screw block drives the arc-shaped plate to move up and down through a push rod, the radius of circular motion of the arc-shaped plate is changed, and therefore the rotating speed of the arc-shaped plate and the driving wheel is changed, and the moving speed of leather to be perforated is increased or decreased; and the perforating speed of a perforator is not changed, so that the perforating distance is increased or decreased, and the effect of conveniently adjusting the perforating distance is achieved.

Description

technical field [0001] The invention relates to the technical field of leather products, in particular to a leather product punching device with adjustable punching distance. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. People can use leather to produce various leather products, including clothing, leather bags, leather goods, etc. [0003] Some leather products need to be punched during the production process to facilitate subsequent processing. The punching methods include manual punching and machine punching. When manually punching leather, the punching efficiency is low, the labor load is large, and the punching distance is not easy to control, resulting in uneven punching, which affects the subsequent processing of leather and wastes leather materials; It has been improved, but the punching distance is not easy to adjust, the operation process is cumbe...
