Abstract

The utility model discloses a winding device for an EVA (Ethylene Vinyl Acetate) film for a solar battery. The winding device comprises a frame, a winding roll, a gas-expansion shaft and a winding roll driving mechanism, wherein the winding roll and the gas-expansion shaft are both mounted on the frame; the output end of the winding roll driving mechanism is connected with the winding roll; the gas-expansion shaft is arranged on a part, close to the winding roll, of the frame; preferably, the winding roll driving mechanism comprises a driving motor and a transmission belt; the winding roll is connected with the output end of the driving motor through the transmission belt; as an improvement, the frame further comprises a spare gas-expansion shaft; and the spare gas-expansion shaft is arranged on a part, close to the gas-expansion shaft, of the frame. According to the winding device for the EVA film for the solar battery, the tightness of winding is more uniform and natural, and the end face of a finished product is flatter.

Description

Solar cell EVA glued membrane wrap-up

Technical field

The utility model relates to a kind of production facilities of solar cell EVA glued membrane, specifically is a kind of solar cell EVA glued membrane wrap-up.

Background technology

The solar cell EVA glued membrane wrap-up of prior art comprises frame, wind-up roll, inflatable axle, wind-up roll driver train and inflatable axle driver train; Said wind-up roll and inflatable axle are installed on the frame, big at interval distance between said wind-up roll and the inflatable axle; The mouth of said wind-up roll driver train links to each other with wind-up roll, and the mouth of said inflatable axle driver train links to each other with the inflatable axle.Said driver train generally comprises drive motor and feed belt, and the feed belt of said two driver trains links to each other with the inflatable axle with wind-up roll respectively.

This type wrap-up adopts initiatively rolling pattern; The power of rolling is provided by drive motor; Because wind-up roll and inflatable axle adopt two driver trains that power is provided respectively, the tightness that exist the velocity of rotation of wind-up roll and inflatable axle inconsistent, to cause rolling is uneven, the smooth inadequately shortcoming of finished product end face.

The utility model content

The utility model technical matters to be solved is the defective that overcomes prior art, and a kind of even nature of tightness, smooth solar cell EVA glued membrane wrap-up of finished product end face of rolling is provided.

For solving the problems of the technologies described above, the solar cell EVA glued membrane wrap-up of the utility model, it comprises frame, wind-up roll, inflatable axle and wind-up roll driver train, said wind-up roll and inflatable axle are installed on the frame; The mouth of said wind-up roll driver train links to each other with wind-up roll, and said inflatable axle is located on the frame position near wind-up roll.

In the solar cell EVA glued membrane wrap-up of the utility model; During the rolling operation; With the inflatable axle is the rewinding rolling-in subsides wind-up roll in axle center, and driver train drives wind-up roll and rotates, and produces friction force between wind-up roll and the rewinding volume; Drive rewinding and furl volume, so the velocity of rotation of inflatable axle and wind-up roll is identical.

The solar cell EVA glued membrane wrap-up of the utility model compared with prior art has the more even nature of tightness, the more smooth advantage of finished product end face of rolling.

As preferably, said wind-up roll driver train comprises drive motor and drive belt, and said wind-up roll links to each other with the mouth of drive motor through drive belt.

As improvement, also be provided with subsequent use inflatable axle on the said frame, said subsequent use inflatable axle is located on the frame position near the inflatable axle.This structure can make the device rolling finish or when breaking down, change subsequent use inflatable axle, enhances productivity at once.

Description of drawings

Accompanying drawing is the structural representation of the solar power EVA glued membrane wrap-up of the utility model.

Shown in the figure: 1, frame, 2, wind-up roll, 3, the inflatable axle, 4, the wind-up roll driver train, 5, drive motor, 6, feed belt, 7, subsequent use inflatable axle.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

As shown in the figure, the solar cell EVA glued membrane wrap-up of the utility model, it comprises frame 1, wind-up roll 2, inflatable axle 3 and wind-up roll driver train 4, said wind-up roll 2 is installed on the frame 1 with inflatable axle 3; The mouth of said wind-up roll driver train 4 links to each other with wind-up roll 2, and said inflatable axle 3 is located on the frame 1 position near wind-up roll 2.

In the present embodiment, said wind-up roll driver train 4 comprises drive motor 5 and drive belt 6, and said wind-up roll 2 links to each other with the mouth of drive motor 4 through drive belt 6.

In the solar cell EVA glued membrane wrap-up of the utility model, during the rolling operation, be the rewinding rolling-in subsides wind-up roll 2 in axle center with inflatable axle 3; Drive motor 5 drives wind-up roll 2 through feed belt 6 and rotates; Produce friction force between wind-up roll 2 and the rewinding volume, drive rewinding and furl volume, so inflatable axle 3 is identical with the velocity of rotation of wind-up roll 2; The tightness of rolling is nature evenly, and the finished product end face is smooth.

As improvement, also be provided with subsequent use inflatable axle 7 on the said frame 1, said subsequent use inflatable axle 7 is located on the frame 1 position near inflatable axle 3.This structure can make the device rolling finish or when breaking down, change subsequent use inflatable axle 7, enhances productivity at once.

Above embodiment only is enumerating for the way of realization of the utility model design; The protection domain of the utility model should not be regarded as and be confined to the concrete form that above embodiment states; The technical personnel of same area can propose the embodiment of equivalent technologies means according to the technical scheme of the utility model design, and these embodiment are all in the protection domain of the utility model.
