Abstract

The utility model relates to a track tool for an EVA glue film finished ring to roll on. The track tool comprises a pair of handheld sleeves and a pair of tracks, wherein the handheld sleeves are arranged at the two ends of a center shaft of the finished ring in a sleeved mode, the tracks are erected on the two sides of the finished ring in parallel in a spaced mode, and the center shaft can roll on the tracks. Continuous teeth are manufactured on the tracks. The surface, used for making contact with the tracks, of the center shaft is provided with teeth the same as the teeth on the tracks. The teeth on the tracks are covered with a layer of elastic silica gel. According to the track tool for the EVA glue film finished ring to roll on, the center shaft located in the middle of the finished ring can roll on the tracks, and therefore the defect that the finished ring is not easy to move is overcome. Besides, the continuous teeth manufactured on the tracks and the continuous teeth manufactured on the center shaft are meshed, and therefore the situation that the finished ring is inclined in the rolling process can be avoided. Finally, the teeth on the tracks are covered with a layer of elastic silica gel, so that vibration and noise generated when the center shaft rolls on the tracks are eliminated.

Description

A kind of track frock that becomes rheogameon to roll for EVA glued membrane

Technical field

The utility model relates to a kind of track frock, is specifically related to a kind of track frock that becomes rheogameon to roll for EVA glued membrane.

Background technology

If solar cell is directly exposed in air, its photoelectric transformation efficiency can decline very soon, loses practical value.Therefore, the research and development of the encapsulation material of solar cell are just very important.For reaching the object being isolated from the outside; adopt transparent, light aging resisting, adhesive property good, can bear atmosphere and change and there is elastomeric ethylene-vinyl acetate copolymer (EVA) glued membrane solar battery sheet is sealed; and be bonded together with levels protective material, form solar module.

EVA is a kind of typical random high molecular compound, in its molecular structure, the irregular arrangement of substituent on strand, in strand, the configuration of unsymmetrical carbon is not identical yet simultaneously, arrange also irregular, therefore it be that a kind of crystallinity is less, polarity and the higher material of elasticity, it has good wellability when heating and melting in addition, during cooling curing, there is good flexibility, anti-stress cracking and adhesive property, be a kind of comparatively desirable can be for the material of solar cell package.

What EVA film forming adopted is extrusion forming process, and whole production line generally includes mixing plant, extrusion equipment, film pressing device, trimming unit and retractable volume equipment, completes batch mixing, material loading, extrudes, calendering, trimming, winding process.Determine will have of end product quality: raw material and formula, hot-melt extrusion process, and casting molding processes is controlled several aspects, and in casting molding processes process, environment temperature and humidity is also an important step, suitable humidity and stable temperature, the Shen of drawing that can reduce film is out of shape, the tension force of controlling diaphragm.

At present, glued membrane will be received and enclose into cylindrically one by one after production, cylindrically by center shaft, runs through, but encloses into larger cylindrical because heavier bad moving one by one.

Utility model content

The technical problems to be solved in the utility model is: propose a kind of being beneficial to and move the track frock that EVA glued membrane becomes rheogameon.

The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of track frock that becomes rheogameon to roll for EVA glued membrane, comprise a pair of for the hand-held sleeve that is set in described one-tenth rheogameon center shaft two ends and a pair of spaced and parallel be erected at the track of the described both sides that become rheogameon for rolling for described center shaft thereon.

Further, be shaped with continuous tooth on described track, described center shaft is shaped with the tooth same with described tooth for also corresponding on the face contacting with described track.

Further, the surface of the tooth on described track is covered with one deck elastic silica gel.

The beneficial effects of the utility model are:

The utility model provides a kind of track frock, and the center shaft that is positioned at into rheogameon middle part can roll on described track, has solved like this rheogameon to move difficult shortcoming.In addition and on track and center shaft, be shaped with the continuous tooth being meshed, can avoid occurring the situation of skew back in rolling process.Finally on the tooth of track, cover vibrations and noise that one deck elastic silica gel rolls in orbit and produces to solve center shaft.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the track frock that becomes rheogameon to roll for EVA glued membrane of the present utility model is described further.

Fig. 1 becomes the structural representation of the track frock of rheogameon rolling for EVA glued membrane in embodiment.

The specific embodiment

Embodiment

Shown in Fig. 1, the track frock that becomes rheogameon to roll for EVA glued membrane in the present embodiment, comprise a pair of for the hand-held sleeve that is set in described one-tenth rheogameon center shaft 2 two ends and a pair of spaced and parallel be erected at the track 1 of the described both sides that become rheogameon for rolling for described center shaft 2 thereon.

On described track 1, be shaped with continuous tooth 3, described center shaft 2 is shaped with the tooth same with described tooth 3 for also corresponding on the face contacting with described track 1.

The surface of the tooth 3 on described track 1 is covered with one deck elastic silica gel.

The track frock that the utility model provides, the center shaft 2 that is positioned at into rheogameon middle part can roll on described track 1, has solved like this rheogameon to move difficult shortcoming.In addition and on track 1 and center shaft 2, be shaped with the continuous tooth being meshed, can avoid occurring the situation of skew back in rolling process.Finally on the tooth 3 of track 1, cover vibrations and noise that one deck elastic silica gel rolls and produces to solve center shaft 2 on track 1.

The above-described embodiment that is not limited to of the present utility model, all employings are equal to replaces the technical scheme forming, and all drops in the protection domain of the utility model requirement.

Claims

1. a track frock that becomes rheogameon to roll for EVA glued membrane, is characterized in that: comprise a pair of for the hand-held sleeve that is set in described one-tenth rheogameon center shaft two ends and a pair of spaced and parallel be erected at the track of the described both sides that become rheogameon for rolling for described center shaft thereon; On described track, be shaped with continuous tooth, described center shaft is shaped with the tooth same with described tooth for also corresponding on the face contacting with described track; The surface of the tooth on described track is covered with one deck elastic silica gel.
