Description

Gluing device for solvent-free compound machine

Technical Field

The invention relates to the field of film production, in particular to a gluing device for a solvent-free compound machine.

Background

The film needs to be rolled on a conveying roller in the production process, the film needs to be cut after the rolling is finished, and the rolled film is easy to loosen because the tail end of the film is not fixed after the cutting; in order to solve the problem, a glue spreading roller is generally adopted to spread glue on the film, and then the tail end of the film is stuck to a glue spreading position; however, after the tail end of the film is bonded and fixed, the film which is not contacted with the tail end of the film is still coated with glue, so that glue waste is caused, and the subsequent rolled film is inconvenient to carry.

Disclosure of Invention

The invention aims to provide a device which is beneficial to saving glue in the film winding process.

In order to achieve the purpose, the technical scheme of the invention provides a gluing device for a solvent-free compound machine, which comprises a frame, a conveying roller, an adjusting unit and a gluing unit, wherein the frame is fixedly provided with a supporting plate, the adjusting unit is positioned below the supporting plate and comprises two adjusting plates which are rotatably arranged on the frame, and the conveying roller is rotatably arranged between the two adjusting plates; a glue cavity filled with glue and a channel communicated with the glue cavity are arranged in the supporting plate, and the glue in the glue cavity flows onto the film through the channel after the film is contacted with the gluing unit; be equipped with the chute in the backup pad, be equipped with the cavity with the chute intercommunication in the backup pad, it is provided with the cutting knife that can extend the backup pad lower surface to slide in the cavity.

The technical effect of the scheme is as follows: the film penetrates through the chute and is wound on the conveying roller, when the film on the conveying roller reaches a certain amount, the film is contacted with the glue coating unit, then the glue in the glue cavity is coated on the film, and after the glue is coated on the film, the film passing through the chute is contacted with the glue to realize adhesion; when the glue is adhered, the two adjusting plates rotate and drive the conveying roller and the film to rotate, and glue is not coated on the film after the film is separated from the gluing unit, so that the glue is saved; the adjusting plate rotates and simultaneously drives the conveying roller to rotate, the conveying roller is in a rotating state, the film passing through the chute completely covers the glue, and the rolled film is convenient to carry subsequently; the film is cut off to the cutting knife roll-over back slip-out from the cavity, because the lateral wall of chute, the lower surface through the film of chute and backup pad form obtuse triangle, so can expose in the chute after the film cutting, pull out the film from the chute when being convenient for to coil next time, and the transfer roller rotates the back simultaneously, and the afterbody of film after the cutting can not bond with glue, is convenient for remove the bonding of film when using the film.

Furthermore, the supporting plate comprises an arc-shaped section and a horizontal section, the glue cavity is arranged in the horizontal section, and the cavity is arranged in the arc-shaped section. The technical effect of the scheme is as follows: the arc-shaped section can extrude and adhere the film covered with the glue, the arc-shaped section enables the film to be firmly bonded before the adjusting plate rotates, the film is separated from the arc-shaped section when the adjusting plate rotates, the film is tightened and bonded with the glue, and the tail part of the cut film is not bonded with the glue, so that the bonding strength is ensured, and the film is convenient to gradually remove the bonding.

Furthermore, the gluing unit comprises a gluing block and a spring, a groove is formed in the horizontal section, the gluing block is arranged in the groove in a sliding mode, the upper end of the gluing block is connected with the bottom of the groove through the spring, a notch is formed in the gluing block, and the channel can be communicated with the notch. The technical effect of the scheme is as follows: the gluing block plugs the channel before the film contacts with the gluing block, the gluing block slides after the film contacts with the gluing block, the channel is communicated with the notch, and glue is coated on the film after passing through the channel and the notch.

Furthermore, the lower end of the gluing block is a curved surface. The technical effect of the scheme is as follows: after the top of the film is wound, force is applied to one side, close to the chute, of the glue coating block, the position of the wrinkle on the film and one side, far away from the chute, of the glue coating block are in contact with each other, the side, at the lower end of the glue coating block, of the glue coating block can be used for scraping the wrinkle position, and the wrinkle position cannot be broken.

Furthermore, a connecting rod is connected between the two adjusting plates, an air cylinder is arranged on the rack, and an output shaft of the air cylinder is rotatably connected with the connecting rod. The technical effect of the scheme is as follows: the two adjusting plates are driven to rotate by one air cylinder, and the structure is simple and practical.

Furthermore, the cylinder is connected with the frame in a rotating way. The technical effect of the scheme is as follows: the phenomenon of locking in the rotating process of the adjusting plate is avoided.

Further, the gluing unit is a sponge layer, and the sponge layer is communicated with the channel. The technical effect of the scheme is as follows: simple structure and glue coating convenience.
