Embodiment 1

[0037] Embodiment 1 is basically as attached figure 1 Shown:

[0038] A file binding device, comprising a horizontally arranged workboard 100, a baffle 101 is vertically fixed on one side of the workboard 100, a puncher 102 is fixed on the top of the baffle 101, and a hole punch 102 is formed between the puncher 102 and the workboard 100. Openings for files to drop in, such as figure 2 As shown, the punching machine 102 includes a hollow housing 103, the housing 103 is rotatably connected with a horizontal shaft 104, and the housing 103 is vertically slidingly connected with three punching nails 105, and the three punching nails 105 are on the same straight line , and the straight line is parallel to the horizontal axis 104, the specific setting of the perforated nail 105 is as follows: a connecting seat 106 is integrally formed on the inner top wall of the housing 103, a chute is vertically opened in the connecting seat 106, and the top of the perforated nail 105 Slidingly...

Embodiment 2

[0046] Embodiment 2 is basically as Figure 6 Shown:

[0047] The difference between embodiment 2 and embodiment 1 is that: an adsorption channel 400 is also provided in the working plate 100, the left end of the adsorption channel 400 is closed, and each hole 300 is connected with the adsorption channel 400, combined with Figure 7 As shown, the connection between the adsorption channel 400 and the hole groove 300 is the necking section 401, and the diameter of the necking section 401 is smaller than the diameter of the adsorption channel 400, and the diameter of the hole groove 300 is 0.2-0.5 mm larger than the diameter of the hole nail.

[0048] On the side wall of the cavity 304, there is also a suction pipe 402 connected to the upper cavity 305 and the adsorption channel 400, and an air intake check valve II is arranged on the suction pipe 402. When the volume in the upper cavity 305 increases , when the air pressure decreases, the intake check valve II opens, and the ga...

Abstract

The invention relates to the technical field of file management equipment, and particularly discloses a file binding device which comprises a working plate, wherein a baffle is fixed on one side of the working plate; a punching machine is fixed on the top of the baffle; the punching machine comprises punching nails which slide up and down; an opening for putting files is formed between the punching machine and the working plate; a hole groove located right below the punching nails is formed in the working plate; a plurality of adsorption holes evenly distributed along the hole groove are formed in the working plate; an air flow channel is arranged in the working plate; the air flow channel comprises a necking section; and each adsorption hole communicates with the necking section and is provided with a first air inlet check valve and an air flow unit for supplying air into the air flow channel. With adoption of the technical scheme, the device solves the problem in the prior art that an operator is at risk of injury by manually pressing paper near the punching nails.

Description

technical field [0001] The invention relates to the technical field of file management equipment, in particular to a file binding device. Background technique [0002] For the industry engaged in file management, the punch machine is an indispensable tool in the office. In order to facilitate storage, many documents are collected, sorted, punched and then bound. The punching equipment currently used usually includes a working board, a baffle is fixed on one side of the working board, and a punching machine is fixed on the top of the baffle. An opening for files to be put in is formed between the working board and the paper is put into the opening, and the punching nails on the punching machine punch holes in the paper. [0003] However, when punching holes, the paper around the punching nails will lift upwards, especially when there are few papers, and the paper lifting will not only be unfavorable for punching holes, but also need to be sorted after the punching is complet...
