Abstract

The utility model discloses a plastic thin film production line with a slitting device. The plastic thin film production line sequentially comprises a feed device, an extrusion device, a drawing device, a corona treatment device and a rolling device, wherein a slitting knife rest shaft is additionally arranged between a first flattening roll and a second flattening roll on the basis of the original equipment body; the knife rest shaft is provided with at least one knife rest; the knife rest is provided with a blade; and the knife rest shaft is controlled by a step motor. According to the plastic thin film production line, a plastic thin film can be formed and slit at a time according to order size, so that the production steps are reduced, the production efficiency is increased, and the production cost is greatly reduced.

Description

Plastic film production lines with cutting device

Technical field

The utility model belongs to mechanical field, is specifically related to plastic film production lines.

Background technology

Extrude the drawing plastic film production line and be generally import equipment; Production line can only be produced the wide-range film of about 2.3 meters of width; And the thin-film width of client's actual needs is generally at 210mm-1200mm, even like this under the situation of existing order, also can only be after production line is produced the film of wide cut; On the plastic sheeting cutting machine, cut again, increased production cost.

The utility model content

Plastic film production lines with cutting device comprises feeding device, extrusion device, stretching device, corona treatment plant, finished rolling device successively;

On the basis of the original finished rolling device apparatus body of plastic film production lines, between first nip rolls and second nip rolls, set up and cut tool axis, be equipped with at least 1 on the tool axis with upper tool post, blade is housed on the knife rest; The frame axle has independent step motor control.

Further, on tool axis, be equipped with 2 or, can better cut like this finished product of different size with upper tool post.

The course of work is following: according to customer demand, the distance between the good tool axis of manual adjustment is fixed a cutting tool when needs cut film, is pressed tool axis stepper motor button, lets tool axis rotate, and cuts film.In the time of need not cutting, press the Electric Machine Control button, tool axis sets back.Film after cutting is through take up roll coiling finished product.

Refill on the take up roll also cuts according to corresponding size, and corresponding with knife rest position and size on the tool axis; On refill, stick two-sided tape, twine smoothly when guaranteeing change of lap, the film of different size will be wrapped on the corresponding refill of take up roll like this.

Beneficial effect: according to the order size, one-shot forming is cut, and has reduced production link, has improved production efficiency, greatly reduces production cost.

Below in conjunction with accompanying drawing, further specifically describe the utility model embodiment.

Description of drawings

A kind of embodiment cutting device of Fig. 1 the utility model structural representation;

Fig. 2 take up roll sketch map;

A kind of embodiment cutting device of Fig. 3 the utility model structural representation.

Among the figure: 1, blade; 2, knife rest; 3, tool axis; 4, first nip rolls; 5, stepper motor; 6, second nip rolls; 7 refills 8, take up roll.

The specific embodiment

Specific embodiment

Like Fig. 1-shown in Figure 2, on the basis of plastic film production lines finished rolling device existing equipment, between first nip rolls 4 and second nip rolls 6, set up and cut tool axis 3, at least more than one knife rest 2 is installed on the tool axis 3, blade 1 is housed on the knife rest 2; Tool axis 3 has 5 controls of independent stepper motor.

Refill 7 on the take up roll 8 also cuts according to corresponding size, and corresponding with knife rest position and size on the tool axis; And on refill, stick two-sided tape, and twining smoothly when guaranteeing change of lap, the film of different size will be wrapped on the take up roll 8 corresponding refills 7 like this.

Among the embodiment 1, Fig. 1, Fig. 2 see, between first nip rolls 4 and second nip rolls 6, have increased and have cut tool axis 3, and two knife rests 2 are installed on the tool axis 3, and blade 1 is housed on the knife rest 2.When needed, adjustment knife rest 2 positions, thus can cut according to the order dimensional requirement.

Among the embodiment 2, Fig. 2 sees, sees between first nip rolls 4 and second nip rolls 6, has increased and has cut tool axis 3, is equipped with at least two on the tool axis 3 with upper tool post 2, and this example is 4, and blade 1 is housed on the knife rest 2.

Refill 7 on the take up roll 8 also cuts according to the corresponding size of order requirements, and the two cooperation realizes disposablely carrying out moulding and cutting, and has reduced production link.

Claims

1. the plastic film production lines that has cutting device comprises feeding device, extrusion device, stretching device, corona treatment plant, finished rolling device successively; It is characterized in that: on the basis of plastic film production lines finished rolling device apparatus body, between first nip rolls and second nip rolls, set up and cut tool axis, be equipped with at least 1 on the tool axis, blade is housed on the knife rest with upper tool post; Tool axis is by step motor control.

2. the plastic film production lines with cutting device as claimed in claim 1, the refill size on the wireline reel cooperates with the tool axis position, posts two-sided tape on the refill.
