Abstract

The utility model relates to a plastic film automatic wrap-up device, which is mainly characterized in that a surface wrap-up roll (1) and a central wrap-up lamping piece (7) combined with clamping rolls (2A), (2B) and a swing type cutter (3) are controlled by a computer; the automatic and uninterrupted wrap-up of plastic film is realized, the utility model can be widely used for automatic wrap-up of various plastic films.

Description

A kind of automatic taking device of plastic film

The utility model relates to a kind of automatic taking device of plastic film

Plastic film winding device in the past often needs manually to assist when changing refill, thereby carrying out continuously of influence production reduced production efficiency.

The purpose of this utility model is to provide a kind of plastic film winding device that can full automaticity carries out the rolling of plastic film incessantly continuously.

The utility model is achieved in that

A kind of plastic film winding device, it is characterized in that: surperficial wind-up roll (1) but the top be provided with niproll (2A), (2B) of the swing of a pair of open and close, the middle upper part of niproll (2A), (2B) is provided with an oscillating type cutting knife (3), and the top of oscillating type cutting knife (3) is provided with air blowing valve (4); The top of air blowing valve (4) is provided with refill supply frame moving up and down refill chuck moving up and down (5); Has a pair of side that places surperficial wind-up roll (1) by the motor-driven swing arm of swinging (6) that is used for the holder (7) of center winding in the working end; Automatically carry out under the control that operates in computer of device.Plastic film sleeve arrives surperficial wind-up roll (1) through live roll (9), is wrapped on the refill (12), is swung the surface of the refill of cramping on surperficial wind-up roll (1) from the both sides by niproll (2A), (2B); When cutting knife cut off film, air blowing valve (4) blew film and is attached to roller (1) surface; By surperficial wind-up roll (1) rotation of driven by motor film is carried out surperficial rolling then.At this moment, one oscillating type cutting knife (3), air blowing valve (4), swing arm (6) all are in the position away from surperficial wind-up roll (1), when the surperficial rolling of film reaches the nominal diameter value, under the driving of cylinder, swing arm (6) is flapped toward the refill (12) on surperficial wind-up roll (1) surface and locates, and a pair of holder (7) clamps refill from both sides, niproll (2A), (2B) arrange to both sides, at this moment, surperficial wind-up roll (1) is worked simultaneously with holder (7), and refill is carried out rolling; Along with the diameter of film volume increases, film volume center correspondingly raises, and drives swing arm (6) swing when the film volume reaches the required diameter exhaust hood, is being with film rolling off cleaved surface wind-up roll (1) surface location, gets back to its default film location that unloads; At this moment, film continues rolling under the driving of holder (7), at this moment, refill chuck (5) is fallen, raise again after emitting the film surface of a refill (12) in motion, while niproll (2A), (2B) swing refill (12) cramping on refill (12) surface on the surperficial wind-up roll (1), then, oscillating type cutting knife (3) is flapped toward surperficial wind-up roll (1) top simultaneously with air blowing valve (4), (at this moment, can manually unload the film volume from center wind-up roll (8)) when by oscillating type cutting knife (3) film being cut off, the film that air blowing valve (4) is sent preceding operation here blows and wraps on the refill (12), like this, rolling work goes on incessantly.The operation of said apparatus is to carry out under the control of computer, and above-mentioned technological process is weaved into computer program input computer, the operation of the electric signal On-line Control device that computer is passed back according to device each several part sensor.

The utility model can be perfect like this:

The another side of surface wind-up roll (1) is from the nearly tension control roll (11) that extremely far is provided with leveling roller (8), deflector roll (9), film nip rolls (10) and film.The effect of film nip rolls (10) is the film traction that preceding operation is sent here, the effect of the tension control roll of film (11) be utilize its cylinder (13) to the control action of its swing arm (14) (promptly when the tension force of film during greater than the elasticity rated value of cylinder (13), cylinder (13) is depressed, make the tension force of film be restricted, when the tension force of film during greater than the elasticity rated value of cylinder (13), cylinder (13) is risen control roll (11), increases the tension force of film) come the tension force of controlling diaphragm in setting range.

The utility model carries out the automatically controlled structure owing to mainly adopted surperficial wind-up roll (1) and center winding holder (7) to cooperatively interact by computing machine, has realized the automatic continuous uninterrupted rolling effect to plastic film.

Fig. 1, a kind of product structure scheme drawing of the present utility model.

Embodiment: (see figure 1)

Surface wind-up roll (1) but the top be provided with niproll (2A), (2B) of the swing of a pair of open and close, the middle upper part of niproll (2A), (2B) is provided with an oscillating type cutting knife (3), the top of oscillating type cutting knife (3) is provided with air blowing valve (4); The top of air blowing valve (4) is provided with refill supply moving up and down and has set up refill chuck moving up and down (5).Has a pair of side that places surperficial wind-up roll (1) by the motor-driven swing arm of swinging (6) that is used for the holder (7) of center winding in the working end; The another side of surface wind-up roll (1) is from the nearly tension control roll (11) that extremely far is provided with live roll (9), film nip rolls (10) and film; Device is established the computer control platform device is carried out full automatic control.

Claims

1, a kind of plastic film winding device, it is characterized in that: surperficial wind-up roll (1) but the top be provided with niproll (2A), (2B) of the swing of a pair of open and close, the middle upper part of niproll (2A), (2B) is provided with an oscillating type cutting knife (3), and the top of oscillating type cutting knife (3) is provided with air blowing valve (4); The top of air blowing valve (4) is provided with on the refill supply frame moving up and down refill chuck moving up and down (5); Has a pair of side that places surperficial wind-up roll (1) by the motor-driven swing arm of swinging (6) that is used for the holder (7) of center winding in the working end; Automatically carry out under the control that operates in computer of device.
