Pressing-wheel fixed-distance punching device

Abstract

The invention discloses a pressing-wheel fixed-distance punching device which comprises a bracket, a spindle part, a driving mechanism, a feeding mechanism and a pressing-wheel assembly. The spindle part is mounted on the bracket and penetrates through the bracket to complete axial motion; and the driving mechanism is mounted on the bracket and makes contacted with the spindle part to drive corresponding components of the spindle part. By operating the driving mechanism, the rotating motion of the driving mechanism is converted to the up-down reciprocating motion of the spindle part, the spindle part generates impact force of the reciprocating motion and matched with corresponding components of a supporting part to punch objects, the feeding mechanism and the pressing-wheel assembly are fixedly mounted on the bracket and are linked with the driving mechanism, after each time of punching movement of the spindle part, the driving mechanism drives the feeding mechanism and the pressing-wheel assembly to convey the punched objects by a certain distance, and thus automatic feeding and fixed-distance punching are achieved.

Description

technical field [0001] The invention relates to a punching device, in particular to a pinch wheel fixed-distance puncher. Background technique [0002] In daily life and work, it is often necessary to punch paper, cardboard, plastic, leather and other items. However, some existing punchers are punched by hand or driven by electricity. There are three problems: [0003] 1. Manual pressing is time-consuming, laborious and inefficient, and because the punch head runs slowly, the edges of the punched holes are rough and irregular; [0004] 2. The general structure of the hole punch driven by electricity is complex, and it cannot work without a power supply, and the operation is also inconvenient. [0005] 3. It cannot be fed automatically to achieve fixed-distance punching. Contents of the invention [0006] The object of the present invention is to provide a pinch wheel fixed-distance puncher which can save time and effort, can punch holes quickly and at a fixed distance, h...
