Paper collecting and shifting device and working method thereof

Abstract

The invention discloses a paper collecting and shifting device. The paper collecting and shifting device comprises a driving unit, a connecting plate, connecting rods III, a fixing plate, a paper blocking plate and a gripper opening block. The driving unit is connected with the connecting plate in a matched mode. The swing end of each connecting rod III is connected with the connecting plate in a hinged mode. The fixed end of each connecting rod III is hinged to the fixing plate. The paper blocking plate is fixed to the connecting plate. The gripper opening block is fixed to the fixing plate and corresponds to a gripper opening ball on a gripper bar. A four-bar mechanism is formed by the connecting plate, the connecting rods III and the fixing plate. The connecting plate can swing up and down with the fixed ends of the connecting rods III as the axis. A working method of the paper collecting and shifting device comprises the steps that after the paper blocking plate is higher than an upper gripper piece of the gripper bar, a lower gripper piece of the gripper bar is opened under the action of the gripper opening block, and loosened paper is blocked by the paper blocking plate; and the gripper bar continues to move forwards, so that the paper falls onto a collection platform naturally after the paper is completely blocked on the gripper bar through the paper blocking plate. The paper collecting and shifting device and the working method thereof have the advantages that the paper is completely separated from the gripper bar in the movement process, the paper is flat during separation, then the paper smoothly falls onto the collection platform, and the collected paper is smoother.

Description

(1) Technical field: [0001] The invention is suitable for printing machinery, especially for die-cutting equipment with a finishing unit, and belongs to a paper receiving and pulling device and a working method thereof. (two) background technology: [0002] The single-fed waste stripping die-cutting equipment uses the tooth row to make the paper circulate in each process station. After the die-cutting action is completed, the tooth row is opened in the finished product cleaning unit, and the paper is smoothly dropped after the paper is pulled, and the paper falls on the collection unit below. After being collected into stacks, it is transported to the outside of the equipment through the logistics system. [0003] In order to realize the function of collecting paper in the finished product unit, the paper receiving and pulling device of the prior art is as figure 1 As shown, it is mainly composed of three parts: a fixed baffle 31 arranged at the mouth of the mouth, a cardbo...

AI Technical Summary

Problems solved by technology

[0004] This technical solution mainly has the following disadvantages: when the equipment is running at high speed, the front end of the paper is caught by the tooth row and stops slowly with the tooth row, but the rear end of the paper will continue to impact towards the front due to the effect of inertia, resulting in paper in the carton The connection point between them is broken, which is not conducive to the collection of paper. At the same time, when the paper stops with the tooth row, before the tooth row opens the teeth, the front end of the paper is held by the tooth row, and the rear end hangs freely. When the row is pulled out, the paper will have a backward movement. Since the rear end of the paper has fallen on the collecting platform, and some connection points between the paper boxes have been broken, it will cause the backward movement of the paper to be unsmooth. This will further aggravate the breakage of the connection point of the carton, resulting in the unsmooth falling of the paper, which will easily cause poor paper collection, or the paper will be messed up here and the machine will stop
