Description

Cutting and reel changing device of solar cell packaging film winding machine

Technical Field

The utility model relates to a film winding machine for film production, in particular to a cutting and roll changing device capable of cutting and separating a full roll of film and winding a new roll of film on a winding shaft in the film winding machine.

Background

The solar photovoltaic module packaging is a key step in the production of solar cells, and in order to ensure the service life and the energy conversion efficiency of the solar cells, a high polymer adhesive film with excellent ultraviolet light aging resistance, transparency and bonding performance is required to be adopted to package the silicon wafer group of the core energy conversion component of the cell.

An extrusion forming process is adopted for a solar photovoltaic module packaging film, an extrusion forming production line of the solar photovoltaic module packaging film generally comprises extrusion equipment, a curtain coating film forming device, a film winding machine and the like, and the film winding machine is indispensable equipment in the packaging film production process. The existing film winding machine mostly adopts a manual winding mode of winding and unwinding, when a winding mandrel is fully wound, the machine must be stopped and then complex manual operations such as coil changing, winding and unwinding are carried out, the quality of coil materials and film products is difficult to guarantee, the operation needs a large amount of labor and operation time, the yield is reduced, the production efficiency is low, and the machine is not particularly suitable for full-flow continuous production, cannot carry out automatic control and automatic operation and does not meet the production requirements of high quality, high efficiency and continuity of the film products. To realize the automatic film winding machine, the problems of cutting and sharing of a full roll of film and winding of a newly-changed roll of film are solved firstly.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a cutting and roll-changing device of a solar cell packaging film winding machine, which can automatically cut and separate a full roll of film and automatically wind a new roll of film.

In order to solve the technical problem, the cutting and roll changing device of the solar cell packaging film winder comprises hinged side plates, a first film guide roller, a second film guide roller, a third film guide roller and a fourth film guide roller are rotatably supported between the two hinged side plates, a rodless cylinder and an electrostatic mounting rod are further mounted between the two hinged side plates, a fly cutter is mounted on the rodless cylinder, and an electrostatic generating rod is mounted on the electrostatic mounting rod; the other end of the hinged side plate is hinged with a swing cylinder.

In the structure, as the electrostatic generator is adopted to generate corona discharge in the cutting and roll changing device, the film can be reliably adsorbed on the friction roller under the action of electrostatic particles so as to realize accurate and rapid cutting of the film, and the cutting and roll changing device has simple structure and reliable adsorption; a rodless cylinder is also adopted in the mechanism as a driving device of the cutting fly cutter, so that the mechanism is compact in structure, greatly saves space, is high in cutting efficiency, and can meet the requirement of long cutting stroke. Therefore, the cutting and roll changing device automatically cuts off and separates the full roll film and automatically winds the new reel film, labor force is greatly saved, and the operation efficiency of the winding machine is effectively improved.

In a preferred embodiment of the utility model, the fly cutter is positioned between a second film guide roller and a third film guide roller which are parallel to each other, and the static electricity generating rod is positioned between the second film guide roller and the first film guide roller; the hinge support side plate is supported on the hinge support shaft. The film can be cut off quickly and accurately.

FIG. 1 is a schematic perspective view of a cutting and reel-changing device of a solar cell packaging film winder according to one embodiment of the present invention;

fig. 2 is an end elevational view of the structure shown in fig. 1.

In the figure, 1-hinged side plate, 2-swing cylinder, 3-hinged shaft, 4-guide film roller I, 5-guide film roller II, 6-guide film roller III, 7-static electricity generating rod, 8-static electricity mounting rod, 9-fly cutter, 10-rodless cylinder and 11-guide film roller IV.

Detailed Description

The cutting and reel changing device of the solar cell packaging film winder shown in fig. 1 and 2 comprises two hinged side plates 1 which are arranged in parallel at a distance, the two hinged side plates 1 are hinged on two side plates of a rack in a swinging mode through hinged supporting shafts 3, a film guide roller I4, a film guide roller II 5, a film guide roller III 6 and a film guide roller IV 11 are rotatably supported between one end portions of the two hinged side plates 1, a rodless cylinder 10 is further installed between the two hinged side plates 1, the rodless cylinder 1 and the film guide roller are arranged in parallel, and a fly cutter 9 is fixedly installed on a sliding component of the rodless cylinder 10. An electrostatic installation rod 8 is also arranged between the two hinged side plates 1, the electrostatic installation rod 8 is also arranged in parallel with the film guide roller, and four electrostatic generation rods 7 are equidistantly arranged on the electrostatic installation rod 8; the static electricity generating rod 9 and the rodless cylinder 1 are all universal products in the market.
