Description

Packaging bag production is with cutting device

Technical Field

The invention relates to the technical field of packaging bag production, in particular to a slitting device for packaging bag production.

Background

The packaging bag is an essential article in daily life. In the manufacturing process of the packaging bag, two layers of single-layer films need to be rewound together to form a double-layer film, the rewound double-layer film is cut into small sections of plastic sheets, and hot pressing is carried out at the later stage, so that the common packaging bag is formed.

When cutting double-deck film into the plastic sheet of segment among the prior art, generally need to convey the film to the cutter through transport mechanism under, then through the vertical removal of drive cutter and cut off into a plurality of plastic sheet with the film, often can cause the film to produce the skew at the in-process of cutting the film among the prior art to the in-process that cuts the film, and the shape of the film of cutting out is influenced to influence the quality of the wrapping bag that produces behind the later stage.

Disclosure of Invention

The invention aims to provide a slitting device for packaging bag production, so as to avoid the influence on the quality of a packaging bag caused by the deviation of a film in the process of cutting the film.

In order to achieve the purpose, the invention adopts the following technical scheme: wrapping bag production is with cutting device, the camera includes a supporting plate, fixedly connected with brace table in the backup pad, vertical sliding connection has the slide in the backup pad, the slide is located one side of brace table, just fixedly connected with cutter on the slide, be equipped with the vertical reciprocating sliding's of drive slide drive unit in the backup pad, the brace table top is equipped with compresses tightly the unit, compress tightly the unit and include mounting panel and clamp plate, the mounting panel with be connected with the elastic component between the clamp plate, the mounting panel with backup pad fixed connection, the one end of clamp plate with the vertical sliding fit of slide, the clamp plate can compress tightly the brace table under the effect of elastic component, the cutter is located when the brace table top the bottom of clamp plate is located the below of cutter.

The principle and the advantages of the scheme are as follows: during the in-service use, convey the brace table on through the film that will wait to cut in this scheme, and pass one side of cutter, then make the vertical reciprocating sliding of slide through control drive unit, thereby make the cutter cut off the film, at the in-process that cuts off the film, owing to be equipped with the clamp plate, the in-process of slide downstream, will make the clamp plate compress tightly the one side of film earlier and fix on the brace table, like this slide downstream and drive the cutter when cutting off the film, can play the fixed effect that compresses tightly to the film, effectually prevent that slip or skew from appearing in the film, thereby make the cutter can play more stable cutting action to the film, make the plastic sheet of cutting out regular more, and then make the wrapping bag shape rule of post processing out neat, the wrapping bag quality of producing is better.

Preferably, as an improvement, a guide groove is formed in one side of the sliding plate, a sliding block is fixedly connected to one end of the pressing plate, and the sliding block is located in the guide groove and is in vertical sliding fit with the guide groove.

So set up, the smooth and easy degree of sliding fit between clamp plate and the slide can be improved in the setting of guide way and slider in this scheme.

Preferably, as an improvement, when the cutter is located above the support table, the slider is located at the bottom of the guide groove.

So set up, when the slider was located the guide way bottom, made the cutter be located a supporting bench top when the drive slide rebound, the film that the cutting was waited to convenient conveying this moment, and the slide can upwards mention the clamp plate, and made the clamp plate also be located a supporting bench top, avoided producing the hindrance to the conveying of film.

Preferably, as an improvement, the drive unit includes a lever and a connecting rod, one end of the lever with the supporting plate is connected in a rotating manner, one end of the connecting rod with the sliding plate is connected in a rotating manner, the other end of the connecting rod with the lever is connected in a rotating manner, and a reset piece for driving the lever to reset is arranged between the supporting plate and the connecting rod.

The drive unit in this scheme can make the lever drive the connecting rod and swing down through the one end of stepping on the lever downwards when using to make the connecting rod drive the slide and slide down, just so can make the cutter on the slide cut the film, and when removing the pressure of applying on the lever, the lever will produce under the effect that resets and reset, is convenient for drive the cutter next time and cuts the film.

Preferably, as an improvement, the piece that resets is the extension spring, the one end of extension spring with the backup pad is connected, and the other end and the lever of extension spring are connected.

So set up, the extension spring is chooseed for use to the piece that resets, and the extension spring installation is more convenient.

Preferably, as an improvement, the supporting plate is fixedly connected with a positioning plate, and the positioning plate and the supporting platform are respectively positioned at two sides of the sliding plate.

The setting of locating plate can play the effect of fixed length cutting to the film of area cutting in this scheme, makes the length of same batch's film cutting the same.

Preferably, as an improvement, the positioning plate is L-shaped.

So set up, can play the effect of support to the tip of film, the cutter is cutting the in-process more steady to the film like this.
