Abstract

The utility model relates to a calender for producing ultrawhite photovoltaic glass, which comprises a base and a support. An upper calendering roller and a lower calendering roller are arranged on the support, and the external diameters of the upper calendering roller and the lower calendering roller respectively are 250-295 mm. Rolling bearing structures are adopted on the two sides of the upper calendering roller and the lower calendering roller. Ceramic transmission roller structures are used on the rear surfaces of the upper calendering roller and the lower calendering roller. With the adoption of the structure, the calender can prevent poor heat radiation effect of the outer surface caused by too thick upper calendering roller and lower calendering roller, avoid the occurrence of roller marks and prevent the deformation of glass panels.

Description

Produce the rolling press that ultra-white photovoltaic glass is used

Technical field

The utility model relates to a kind of rolling press, a kind of rolling press that ultra-white photovoltaic glass is used of producing of saying so more specifically.

Background technology

At present, anxiety along with the energy, the development of photovoltaic product is rapid day by day, and as production molding device---the rolling press of solar energy photovoltaic glass cover-plate glass, wherein the characteristics of equipment have not only determined the glass production capacity, yield rate, the visual appearance of glass, the more direct transmittance that affects glass of photovoltaic glass manufacturer.

Now rolling press manufacturers mainly is a Germany and Japanese in the world.Purchase cost height so not only, but also have a lot of defectives.The first, the stack external diameter that rolling press uses is crossed thick or meticulous; The second, the supporting plate cisten mechanism is adopted in rolling press home roll back more, and its shortcoming is that the supporting plate water tank adopts the inner water flowing of water bag, surface with wind they to be held up, and this structure causes the glass-board surface distortion because of the difficult control of air quantity size; The 3rd, sliding surface bearing is adopted in the stack transmission, and is easy of like this glass generation roll marks; The 4th, the brick in stack front---lip tile is fixed on above the rolling press, and its shortcoming is can bring defective when lip changes to sheet glass because of breach appears in erosion, and lip tile can't separate certain distance with the rolling press one, can't regulate the defective that glass produces.

Summary of the invention

The purpose of this utility model is will provide a kind of can solve because the supporting plate cisten mechanism causes rolling press that the glass deformation of producing and Germany produces because the rolling press that the bearing shell structure brings the production ultra-white photovoltaic glass of the problem of roll marks to use.

The purpose of this utility model is achieved in that

Produce the rolling press that ultra-white photovoltaic glass is used, comprise base and support, be provided with calendering top roll and calendering lower roll on support, described calendering top roll and calendering lower roll external diameter are 250～295mm.

Adopt rolling bearing structure at described calendering top roll and calendering lower roll both sides.

Ceramic delivery roll structure is used in described calendering top roll and calendering lower roll back.

Owing to adopt said structure, this rolling press had the following advantages:

A. can prevent from excessively slightly to cause the outside surface radiating effect poor because of the calendering up-down rollers;

B. can avoid the appearance of roll marks;

C. prevent the glass-board surface distortion.

Embodiment

Shown in Fig. 1,2,3,4, in the preferred embodiment of rolling press shown in the utility model, comprise base 10 and support, support comprises bearing 9 and upper bracket 7 fixed thereon, be provided with calendering top roll 1, calendering lower roll 2 and ceramic delivery roll 3 on upper bracket 7, calendering up-down rollers 1,2 both sides are provided with rolling bearing 11.Upper bracket 7 is provided with the turbine and worm 8 of regulating calendering up-down rollers 1,2 spacings, rolling press bearing 9 links to each other with spiral lifting device 5, guide pillar 6, spiral lifting device 5 can make rolling press bearing 9 reach with the whole liter in upper part or fall, and guide pillar 6 can make space, rolling press process of rising or falling middle and upper part more stable.Spiral lifting device 5, guide pillar 6 are fixedly linked with rolling press base 10.Rolling press base 10 is located on the track on ground with the both sides wheel 4 that links to each other.Rolling press is whole can be moved on ground rail together by wheel 4, realizes the turnover function of rolling press.

Calendering top roll driving motor 15, calendering lower roll driving motor 16 and ceramic delivery roll motor 17 link to each other with ceramic delivery roll with calendering top roll 1, calendering lower roll 2 by versatile spindle, calendering top roll driving motor 15, calendering lower roll driving motor 16 link to each other with the electrical control cabinet of far-end with ceramic delivery roll motor 17, and control rotating speed of motor such as servo-driver, PLC are arranged in the housing.But calendering top roll driving motor 15, calendering lower roll driving motor 16 and ceramic delivery roll motor 17 independent control calendering top roll 1, calendering lower roll 2, ceramic delivery roll 3 speed.

In order to solve the defect problem that lip tile 12 and rolling press one cause to sheet glass, its calendering lip tile 12 is fixed on the kiln, with the kiln one, rolling press by turbine screw mandrel or motor reducer structure regulate rolling press up and down or position, the left and right sides, just can regulate separately, prevent the defect problem that brings to sheet glass with the lip tile one.

The thickness of glass is to realize by the spacing between control calendering top roll 1 and the calendering lower roll 2; The colored type of glass is by being formed by calendering top roll 1 roll body flower type and the compacting of calendering lower roll 2 bodies flower type.

Logical water coolant in calendering top roll 1, calendering lower roll 2 rollers, constant to guarantee calendering up-down rollers 1,2 roll surface temperatures.

Concrete working process:

The good glass metal tail brick outside the slime flux mouth of melting furnaces 13 fusings is sent to annealing furnace through ceramic delivery roll to anneal after stack compression moulding, again through cold junction cutting, stacking, packing warehouse-in.
