Abstract

An extrusion piece machine with membrane function comprised of hopper, extrusion device, die head, piece material molding device, and coiling device. Piece molding device includes three-roller rolled device, cooling transmission roller, and traction roller. It is characterized in that the piece molding device is covered with a membrane device including a frame. The frame is set with a thin film de-coiling axis. A nip roller is set between the three-roller rolled device and die head, and at least one guide roller is set between thin film de-coiling axis and nip roller. The nip roller is metal roller engraved with left and right screw grooves, arc and pillow rubber roller. Guiding roller of membrane device is set with pressure sensor, and membrane de-coiler axis is set with brake and machine expansion device or gas-expansion device; the machine completes piece and membrane covering techniques with one machine at the same time, thus lowering equipment investment and production cost. Its membrane technique is quick and convenient, and quality reliable. In addition, the production efficiency is enhanced as well. So it is practical.

Description

Extrusion sheet machine with overlay film function

Technical field

The utility model relates to a kind of plastic extruder, reliable, the convenient smooth extrusion sheet machine with overlay film function of particularly a kind of compound film quality.

Background technology

At present, in order to strengthen the decoration result of the packing of product, pattern, trade mark and the description of product of various patterns on packing box, have been designed, with propaganda strength and the expansion marketing scope that increases product, and the existing equipment of making packaging material all is to adopt the extrusion sheet machine, just raw material are cast into plastic sheet through the extrusion sheet machine, do not possess the overlay film function, for blooming must be purchased a laminating machine in addition, so just increased the cost input of plant equipment, and production process is time-consuming takes a lot of work, and production efficiency is low.

In view of this, in order to overcome above-mentioned shortcoming, this creator is according to oneself practical experience and technical concept, after deliberation, exploitation, and has the utility model to produce eventually.

The utility model content

The utility model is that a kind of extrusion sheet machine with overlay film function will be provided, with solution make that it is convenient and swift, the technical problem of reliable quality overlay film and dual-use.

It is such solving the problems of the technologies described above the technical scheme that is adopted:

A kind of extrusion sheet machine with overlay film function, include hopper, extrusion device, die head, sheet forming device and wrap-up, the sheet forming device comprises that three roll-ins of calendered sheet prolong device, cooling delivery roll and carry-over pinch rolls, it is characterized in that: installing one film covering device on this sheet forming device, film covering device includes a support body, set up a film unreeling shaft on the support body, prolong the nip rolls that sets up a conveying flattening film between device and the die head in three roll-ins, and between film unreeling shaft and nip rolls, install at least one guide roller;

The support body of this film covering device and film unreeling shaft are set up in the cooling delivery roll top of sheet forming device, or three roll-ins prolong the device left side, or the device top is prolonged in three roll-ins;

This nip rolls is the surperficial metallic roll that is carved with left hand thread groove and right-handed thread groove, or arc rubber rollers, or thin ends and thick middle pincushion rubber rollers;

The guide roller of this film covering device is equiped with pressure sensor;

This film unreeling shaft is equiped with brake and bloated device of machine or inflatable device.

The utility model is to install film covering device additional on plastics extrusion sheet machine, nip rolls by film covering device is sent into three roll-ins to film and is prolonged above or below the sheet material inlet of device, make film and sheet material together prolong the sheet material that the device calendering forms the tool overlay film through three roll-ins, convenient and swift, the reliable in quality of its overlay film, realized that an equipment finishes sheet material and coating technique simultaneously, reduced production cost, thus solved make that it is convenient and swift, the technical problem of reliable quality overlay film and dual-use.

The utility model is simple in structure, and its advantage is as follows:

1, the utility model is at an equipment sheet material and coating technique to be finished simultaneously, has reduced the equipment input, has reduced production cost.

2, coating technique of the present utility model, convenient and swift, reliable in quality has improved production efficiency again, and the tool practicality.

Description of drawings

Fig. 1 is an example structure schematic diagram of the present utility model.

Fig. 2 is another example structure schematic diagram of the present utility model.

Fig. 3 is an another example structure schematic diagram of the present utility model.

The specific embodiment

As Fig. 1,2, shown in 3, be three example structure schematic diagrames of the present utility model, this has the extrusion sheet machine of overlay film function, include hopper 11, extrusion device 12, die head 13, sheet forming device 20 and wrap-up 24, sheet forming device 20 comprises that three roll-ins of calendered sheet 41 prolong device 21, cooling delivery roll 22 and carry-over pinch rolls 23, wherein, installing one film covering device 30 on this sheet forming device 20, film covering device 30 includes a support body 31, set up a film unreeling shaft 34 on the support body 31, prolong the nip rolls 33 that sets up a conveying flattening film 42 between device 21 and the die head 13 in three roll-ins, and between film unreeling shaft 34 and nip rolls 33, install at least one guide roller 32;

The support body 31 of this film covering device 30 and film unreeling shaft 34 are set up in cooling delivery roll 22 tops (as shown in Figure 1) of sheet forming device 20, or three roll-ins prolong device 21 left sides (as shown in Figure 2), or device 21 tops (as shown in Figure 3) are prolonged in three roll-ins;

This nip rolls 33 is the surperficial metallic roll that is carved with left hand thread groove and right-handed thread groove, or arc rubber rollers, or thin ends and thick middle pincushion rubber rollers (not shown);

The guide roller 32 of this film covering device 30 is equiped with the pressure sensor (not shown);

This film unreeling shaft 34 is equiped with brake and bloated device of machine or inflatable device (not shown).

During use, the nip rolls 33 of this machine by film covering device 30 sent into three roll-ins to film 42 and prolonged above or below sheet material 41 inlets of device 21, make film 42 together prolong device 21 calenderings and form laminated sheet 40 through three roll-ins with sheet material 41, convenient and swift, the reliable in quality of its overlay film, realized that an equipment finishes sheet material and coating technique simultaneously, reduce production cost, improved production efficiency, and the tool practicality.
