An automatic test paper binding device

Abstract

An automated complete book binding device for test papers, including a workbench, the four corners of the bottom of the workbench are respectively fixed with table legs, the rear of the top of the workbench is fixedly connected to a vertical board, the upper part of the front of the vertical board is fixedly connected to the back of a horizontal board, and the bottom of the horizontal board The two sides of the two sides are respectively fixedly connected to the upper end of the electric push rod, and the lower end of the electric push rod is fixedly connected to the top surface of the horizontal plate. A row of several first through holes is opened on the top surface of the horizontal plate, and the bottom surface of the first through hole is respectively fixed and installed. Open vertical cylinder, the lower end of the vertical cylinder is an annular knife edge, and the front side of the top surface of the workbench is provided with several second through holes, and the grinding device capable of grinding the bottom of the corresponding vertical cylinder is provided in the second through holes. When the device is punching holes, it can realize the automatic cleaning of the vertical tube, and discharge the paper scraps in the vertical tube out of the vertical tube, which is convenient for the user to clean and collect the paper scraps, avoids the blockage of the vertical tube, and improves the reliability of the vertical tube. To ensure the punching effect of the vertical cylinder.

Description

technical field [0001] The invention belongs to the field of binding devices, in particular to an automatic test paper binding device. Background technique [0002] Examination paper binding is a heavy part of school examination affairs. Due to the uniformity of the examination time, not only are there a large number of test papers bound each time, but most of them are purely manual, so the binding efficiency is low. At present, the test paper binding work is mainly carried out by teachers. The way of punching, threading, and threading is completed, which consumes a lot of time and energy. Because the test paper is thicker overall, it takes a lot of time and energy to bind and punch, which is inconvenient for users. Contents of the invention [0003] The invention provides an automatic test paper binding device to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] An automated complete book b...
