Description

Threaded thick book binding machine

technical field

The invention relates to a binding device, in particular to a threading thick book binding machine.

Background technique

At present, common ordinary staplers are often suitable for binding paper of about 5 mm. But in daily life, it is often necessary to bind relatively thick materials, such as many copied materials bound into one book, multiple monthly magazines of the same year in the library need to be bound into adult volumes, etc., the binding thickness can reach about 5 cm. But existing binding equipment has some complex structures, high cost, inconvenient use, and not very good use effect. Some bookbinding thickness can only be about 5 mm, which seriously cannot meet the needs of thick book binding.

Contents of the invention

The object of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a thick book binding machine with threading, which is simple in structure, easy to use, low in cost, and good in binding effect.

To achieve the above object, the present invention adopts the following technical solutions:

The lead wire device includes a connecting rod connected with the crank of the needle threading device, the lower end of the connecting rod is connected with one end of the driving shaft arranged in the cavity of the base, the driving shaft is equipped with a driving bevel gear, and the other end of the driving shaft extends to the base The other cavity of the base is connected with the gear sector; the driving bevel gear meshes with the driven bevel gear set in the cavity of the base, and the driven bevel gear is coaxially installed with the hook mechanism.

The hook mechanism includes a bobbin located at the center, an arc-shaped hook is arranged outside the bobbin, and one end of the arc-shaped hook is a bifurcated structure.

The needle of the needle-threading device corresponds to the hook plate of the thread-guiding device.

The workbench is provided with a clamping device, the bottom of the workbench is fixedly connected with the rack, and the rack is meshed with the gear sector.

The clamping device includes a clamping bolt fixed on the workbench, a clamping gasket is covered on the clamping bolt, and a clamping nut is arranged on the upper part of the clamping gasket to cover the clamping bolt.

The working principle of the present invention is as follows:

Clamping: Place A4 paper with a thickness of 50mm on the workbench, and rotate the clamping nut to fix the paper on the workbench. Get the pre-prepared bench drill to drill 7 holes with a diameter of 2mm and a hole spacing of 40mm. A 2 mm diameter wire is threaded through the structure.

Threading: The rocker arm is used to drive the needle to move up and down along the guide shaft through the crank and swing arm; the drive shaft is driven to rotate through the connecting rod, so that the driven bevel gear is driven to rotate through the driving bevel gear, and the hook plate rotates with the driven bevel gear. When the needle moves up about 2mm from the bottom end, the position of the hook plate B is just tangent to the needle, slide the thread to the hook thread position between B and C, and after one turn, the main line and the bottom thread intersect.

Matching: Binding A4 paper with a thickness of 50mm requires drilling 7 holes with a diameter of 2mm and a hole spacing of 40mm. Thread with a 2mm diameter thread. The purpose of the tooth sector is to strictly ensure that the table advances 40mm each time, which can be achieved by designing the tooth sector and the rack. When the needle moves up and down 50mm above the worktable, the gear fan and the rack mesh, and the worktable moves forward 40mm, aligning the next punched hole with the needle. At this time, the gear fan and the rack are separated, and the workbench does not move. The needle continues to move for threading until the next time the needle moves to 50mm higher than the working table, the tooth fan and the rack are engaged again, and the working table moves 40mm.

The beneficial effects of the present invention are that the present invention can be widely used in the binding work of test papers, newspapers, magazines, files and files of schools, financial institutions, state agencies and other departments. The binding machine has the advantages of simple structure, convenient use, low cost and good binding effect.
