Description

Technical Field

[0001] The utility model belongs to the technical field of EVA film production equipment, and particularly relates to an EVA film heating and flattening device. Background Art

[0002] EVA film is a high-viscosity thin film material sheet made from high molecular resin (ethylene-vinyl acetate copolymer) as the main raw material, added with special additives and processed by special equipment. In the industry, it is also called modified "EVA laminated glass film". It has a strong adhesion to inorganic glass and has characteristics such as toughness, transparency, heat resistance, cold resistance, large bonding strength, high elongation at break, and good moisture resistance. It is the most common encapsulation material in the manufacture of solar photovoltaic modules, and is also an ideal and economical adhesive material for manufacturing safety laminated glass in the world at present. It can partially replace PVB materials and be used in the automotive and construction industries. The safety laminated glass produced with it can achieve ideal effects such as safety, heat preservation, wind resistance, impact resistance, sound insulation, and ultraviolet protection.

[0003] The preparation process of EVA film is to mix various additives into EVA particles, and then melt and extrude them into a film. The EVA film extruded from the die head of the extruder needs to be conveyed over a long distance through multiple sets of conveying rollers. During the conveying process, the EVA film is cooled and shaped, and finally wound up. When the EVA film is wound into a roll, due to too much tension, the film is too tight after winding, resulting in strip-shaped protrusions on the film; in addition, with the trend of cost reduction and efficiency improvement in the industry, large-roll EVA is beginning to be used, and the length of a single roll of EVA is increasing continuously. The pressure on the inner film increases, resulting in film deformation and forming block-shaped protrusions. In order to improve the use effect of the EVA film, it is necessary to flatten the film.

[0004] At present, the flattening operation is carried out manually, that is, manually holding a scraper to flatten the protruding part of the EVA film. However, the manual flattening method has low efficiency and cannot guarantee the flattening quality, the effect is average, and it cannot solve the problem of film width shrinkage caused by low temperature. When manually using a scraper to flatten, due to the limited pressure applied, some protrusions cannot be flattened; it is easy to scratch the film itself and damage the film material; manual operation is prone to causing the film to be not centered, resulting in poor edge glue shortage after subsequent lamination. Content of the Utility Model

[0005] The utility model provides an EVA film heating and flattening device with reasonable structural design, good flattening effect and high working efficiency to solve the technical problems existing in the known technology.

[0006] The technical solution adopted by the present utility model to solve the technical problems existing in the known technology is as follows: An EVA film heating and flattening device includes a bracket with feet and casters installed at the bottom.

It also includes a limit adjustment component installed on the bracket tabletop for adjusting the position of the support table structure; A lifting bracket is installed on the bracket tabletop, and a vertically movable lifting mounting seat is installed on the lifting bracket. It also includes a lifting drive component for driving the lifting of the lifting mounting seat; A plurality of laterally extending cross-movement guide rails are fixedly connected to the front side of the lifting mounting seat. A pressing component with a lockable position is connected to the cross-movement guide rails through sliders; On both sides of the pressing component, a first roller pressing component and a second roller pressing component that are slidably connected to the cross-movement guide rails through sliders are respectively provided. Both the first roller pressing component and the second roller pressing component have a heating function; It also includes a cross-movement drive structure for driving the first roller pressing component and the second roller pressing component to move horizontally towards / away from each other synchronously.

[0007] The advantages and positive effects of the present utility model are as follows: The present utility model provides an EVA film heating and flattening device. By setting the first roller pressing component and the second roller pressing component with heating functions and cooperating with the cross-movement drive structure, the film can be heated and flattened to replace the manual scraping operation, with high work efficiency and good flattening effect. Since both the first roller pressing component and the second roller pressing component have heating functions, the problem of wide-width shrinkage of the film can be well solved during the flattening operation of the film; By setting the pressing component, the film can be pressed and positioned to prevent the film from moving during the heating and flattening process, enabling the film to be centered; By setting the lifting drive component, the first roller pressing component, the pressing component, and the second roller pressing component can be driven to move vertically as a whole, so that there is enough feeding space between the roller pressing component and the support table structure, ensuring the smooth progress of the feeding operation; By setting the limit adjustment component, the lateral position of the support table structure can be adjusted, increasing the operation range of the first roller pressing component and the second roller pressing component, and avoiding unflattened parts on the film.

[0023] In order to further understand the invention content, features and effects of the present utility model, the following embodiments are given for detailed description as follows:

[0024] Please refer to Figure 1 , the EVA film heating and flattening device of the present utility model includes a bracket 1 with feet and casters installed at the bottom.

A strip-shaped hole is opened in the first limit member 4-2, and the first limit member 4-2 is connected to the bracket tabletop 3 through bolts passing through the strip-shaped hole.

[0026] The extending direction of the first limit member 4-2 is the same as the extending direction of the transverse guide rail 8. An adjustment mounting seat 4-1 is inserted between the two sets of first limit members 4-2; second limit members 4-3 connected to the bracket tabletop 3 are arranged at both ends of the adjustment mounting seat 4-1; strip-shaped holes are opened in both the first limit member 4-2 and the second limit member 4-3, and each limit member is connected to the bracket tabletop 3 through screws passing through the strip-shaped holes; it also includes a fine adjustment card slot block 4-4 fixedly connected to the top surface of the adjustment mounting seat 4-1, and the support table structure 5 is clamped with the fine adjustment card slot block 4-4.

[0027] As Figure 2 shown, the support table structure 5 includes a support table body 5-1 for supporting the glass plate. A fine adjustment clamping member 5-2 clamped with the fine adjustment card slot block 4-4 is fixedly connected to the bottom surface of the support table body 5-1, and the fine adjustment clamping member 5-2 is rod-shaped.

[0028] By setting the limit adjustment component 4, the horizontal position of the support table structure 5 can be adjusted according to the width of the film and the size of the glass plate, and then the positions of the glass plate and the film placed on the support table structure 5 can be adjusted.

[0029] As Figure 1 shown, a lifting bracket 13 is installed on the bracket tabletop 3. A liftable lifting mounting seat 6 is installed on the lifting bracket 13. It also includes a lifting drive component 2 for driving the lifting mounting seat 6 to lift.

[0030] Further refer to Figure 3, in this embodiment, the lifting drive assembly 2 includes a longitudinally arranged lifting guide rod 2-5 fixedly connected to the lifting bracket 13. A lifting seat 2-6 is slidably connected to the lifting guide rod 2-5 through a linear bearing, and the lifting seat 2-6 is connected to the lifting mounting seat 6. It also includes a longitudinally arranged lifting lead screw 2-4 rotatably connected to the lifting bracket 13. The lifting seat 2-6 is connected to the lifting lead screw 2-4 through a nut.

[0031] When the lifting motor 2-1 is started, it can drive the lifting driving sprocket 2-2 mounted thereon to rotate. Under the action of the chain, it further drives the driven sprocket 2-3 to rotate. Driven by the rotation of the driven sprocket 2-3, the lifting lead screw 2-4 rotates, and then drives the lifting seat 2-6 to lift, finally achieving the purpose of longitudinally moving the lifting mounting seat 6.

[0032] As Figure 1 shown, in order to install the operating end for smoothing the adhesive film, this embodiment further includes a plurality of laterally extending transverse guide rails 8 fixedly connected to the front side of the lifting mounting seat 6. In this embodiment, two sets of transverse guide rails 8 are provided. A material pressing assembly 10 with a lockable position is connected to the transverse guide rails 8 through sliders, that is, a locking knob that can be tightened against the transverse guide rails 8 is installed on the material pressing assembly 10.

[0033] Further referring to Figure 5 , in this embodiment, the material pressing assembly 10 includes a plate cylinder seat 10-3 slidably connected to the transverse guide rails 8 through sliders. The locking knob is installed on the plate cylinder seat 10-3. When it is necessary to adjust the lateral position of the material pressing assembly 10, the locking knob installed on the plate cylinder seat 10-3 can be loosened, and then the position of the plate cylinder seat 10-3 is moved. After adjusting to the appropriate position, the locking knob is tightened again. A plate lifting cylinder 10-5 with its extending end facing downwards is installed on the plate cylinder seat 10-3. A plate mounting seat 10-2 is installed on the extending end of the plate lifting cylinder 10-5. A material pressing plate 10-1 is connected to the plate mounting seat 10-2. In this embodiment, the material pressing plate 10-1 is a plate that can be heated.

In this embodiment, the heating time and temperature of the material pressing plate 10-1 can be preset. The material pressing assembly 10 further includes a longitudinally arranged plate lifting guide rod 10-4 installed on the plate mounting seat 10-2. The plate lifting guide rod 10-4 is slidably connected to the plate cylinder seat 10-3 through a linear bearing.

[0034] During the actual working process, the extension of the piston rod of the plate lifting cylinder 10-5 can drive the pressure plate 10-1 to move downward until the pressure plate 10-1 presses on the support table structure 5 or the adhesive film on the glass plate placed on the support table structure 5, thereby realizing the operation of initially positioning the adhesive film and avoiding the displacement of the adhesive film during subsequent operations.

[0035] In order to smooth the adhesive film on the support table structure 5 or on the glass plate placed on the support table structure 5, this embodiment further includes a first roller pressing assembly 9 and a second roller pressing assembly 11 respectively arranged on both sides of the pressure component 10. Both the first roller pressing assembly 9 and the second roller pressing assembly 11 are slidably connected to the transverse movement guide rail 8 through sliders, and further includes a transverse movement driving structure for driving the first roller pressing assembly 9 and the second roller pressing assembly 11 to move horizontally towards / away from each other synchronously.

[0036] See further Figure 6 , the transverse movement driving structure includes a transverse movement sprocket pair 7 installed on the lifting mounting seat 6, and further includes a transverse movement driving assembly 12 connected to the transverse movement sprocket pair 7; both the first roller pressing assembly 9 and the second roller pressing assembly 11 are connected to the transverse movement sprocket pair 7.

[0037] Furthermore, the transverse movement sprocket pair 7 includes a correspondingly arranged transverse movement driven sprocket 7-1 and a transverse movement driving sprocket 7-4 rotatably connected to the lifting mounting seat 6. A closed transverse movement transmission chain 7-2 is drivingly connected between the transverse movement driven sprocket 7-1 and the transverse movement driving sprocket 7-4. The first roller pressing assembly 9 is connected to the upper straight section of the transverse movement transmission chain 7-2, and the second roller pressing assembly 11 is connected to the lower straight section of the transverse movement transmission chain 7-2; it further includes a chain guiding member 7-3 installed on the lifting mounting seat 6 for guiding the straight section of the transverse movement transmission chain 7-2.

[0038] Among them, the transverse movement driving assembly 12 includes a transverse movement driving motor 12-1 installed on the lifting mounting seat 6. A driving transmission pair 12-2 is connected between the output shaft of the transverse movement driving motor 12-1 and the transverse movement driving sprocket 7-4. The driving transmission pair 12-2 includes a driving sprocket key-connected to the output shaft of the transverse movement driving motor 12-1, and further includes a driven sprocket key-connected to the rotating shaft of the transverse movement driving sprocket 7-4. A transmission chain is drivingly connected between the above-mentioned driving sprocket and the driven sprocket.

[0039] See further Figure 4, in this embodiment, the first roller pressing assembly 9 includes a roller pressing cylinder base 9-3 slidably connected to the transverse movement guide rail 8 through a slider. A roller pressing lifting cylinder 9-5 with its extending end facing downward is fixedly connected to the roller pressing cylinder base 9-3. A roller pressing mounting seat 9-2 is installed at the extending end of the roller pressing lifting cylinder 9-5. A smoothing roller 9-1 is rotatably connected to the roller pressing mounting seat 9-2. The smoothing roller 9-1 is a roller that can be heated, which belongs to the prior art. The roller pressing lifting cylinder 9-5 can effectively control the lifting of the smoothing roller 9-1. The first roller pressing assembly 9 further includes a longitudinally arranged roller pressing lifting guide rod 9-4 installed on the roller pressing mounting seat 9-2. The roller pressing lifting guide rod 9-4 is slidably connected to the roller pressing cylinder base 9-3 through a linear bearing.

[0040] A Teflon protective layer is provided on the outer layer of the smoothing roller 9-1. On the one hand, the EVA film will not stick to the Teflon protective layer, reducing the possibility of the film displacement. On the other hand, it protects the EVA film and prevents the smoothing roller 9-1 from damaging the EVA film when rolling.

[0041] Since the widths of EVA films of different patterns are different, it is also necessary to replace the smoothing rollers 9-1 with different lengths. To facilitate the installation of the smoothing roller 9-1, in this embodiment, the roller pressing mounting seat 9-2 includes a mounting plate member. Strip-shaped holes are opened at both ends of the mounting plate member, and locking bolts are inserted into the strip-shaped holes. Two groups of mounting vertical plates are connected through the above bolts. Both ends of the smoothing roller 9-1 are connected to the above two groups of mounting vertical plates through rolling bearings. Therefore, the disassembly and assembly are relatively convenient to fit different lengths of smoothing rollers 9-1.

[0042] In this embodiment, the structures of the first roller pressing assembly 9 and the second roller pressing assembly 11 are the same.

[0043] During operation, the two smoothing rollers roll and smooth from the middle to both ends respectively, keeping the forces on both sides of the film equal. At the same time, cooperating with the material pressing assembly 10, it can better prevent the film from displacement. To avoid areas on the film that are not smoothed by the first roller pressing assembly 9 and the second roller pressing assembly 11, if necessary, the lateral position of the support platform structure 5 can be adjusted through the limit adjustment assembly 4, so that the first roller pressing assembly 9 and the second roller pressing assembly 11 can heat and smooth the areas on the film that are not smoothed.

[0044] Working process:

[0045] The lifting drive assembly 2 drives the lifting mounting base 6 to move upward to a preset position, so as to leave enough feeding space between the rolling press assembly and the support table structure 5. Place the glass plate and the EVA film on the support table structure 5, so that the EVA film is located below the rolling press assembly; then the lifting drive assembly 2 drives the lifting mounting base 6 to move downward to a preset position. The piston rod of the plate lifting cylinder 10-5 in the material pressing assembly 10 extends to drive the material pressing plate 10-1 to move downward until the material pressing plate 10-1 presses on the film to prevent the film from moving around, so that the film can be centered; then, the piston rods of the pressing roller lifting cylinders in the first rolling press assembly 9 and the second rolling press assembly 11 extend to drive the corresponding flattening pressing rollers to move downward until they press on the film; then the transverse movement drive motor 12-1 in the transverse movement drive assembly 12 starts, driving the first rolling press assembly 9 and the second rolling press assembly 11 to move at a moderate speed. With their own gravity, the flattening pressing rollers move back and forth in a rolling manner, so as to preferably flatten the film. In addition, since the flattening pressing rollers have a heating function, the forward and backward rolling flattening pressing rollers can well solve the problem of the width shrinkage of the film; when there are parts on the film that are not flattened by the first rolling press assembly 9 and the second rolling press assembly 11, the lateral position of the support table structure 5 is adjusted through the limit adjustment assembly 4, so that the first rolling press assembly 9 and the second rolling press assembly 11 can heat and flatten the unflattened parts of the film.
