Big data test paper automatic binding device

Abstract

The invention discloses a big data test paper automatic binding device. The big data test paper automatic binding device comprises a box butting against the ground; an inner cavity is fixedly arrangedin the box; a through cavity communicates into the upper end wall of the inner cavity; the through cavity communicates with external space; left and right symmetrical cavities communicate into the back end wall of the inner cavity; tooth discs are arranged in the symmetrical cavities; a clamping cavity, positioned in the back end wall of the inner cavity, is formed between the symmetrical cavities; a connecting rod is fixedly arranged between the tooth discs; and the connecting rod is connected with the symmetrical cavities and the end walls of the clamping cavity in a rotating fit mode. Thedevice is simple in structure and convenient to use, adopts a cam clutching structure to synchronously shift lifting structures on the left and right sides to achieve more smooth clamping and aligningprocess of test papers, and meanwhile, uses a ratchet tooth structure to singly drive a clamping structure to move to achieve multiple functions of automatic alignment function so as to easily realize binding of the test papers.

Description

technical field [0001] The invention relates to the field of test paper binding, in particular to a big data automatic binding device for test papers. Background technique [0002] Examination papers need to be bound in the process of batch correction or delivery. The process of binding often involves the steps of revision and neat arrangement of test papers. The existing test paper binding equipment has a single structure and a low degree of automation to a certain extent. In actual use, there is a lack of many adjustment functions, and this device effectively solves this problem. Contents of the invention [0003] The object of the present invention is to provide a large data type test paper automatic binding device, which can overcome the above-mentioned defects of the prior art. [0004] According to the present invention, a large data type automatic binding device for test papers of the equipment of the present invention includes a box that touches the ground, an inn...
