Description

Technical Field

[0001] The invention relates to the technical field of film laminating machines, in particular to a film laminating machine for rolled solar heat collecting sheet strips. Background Art

[0002] At a time when the solar energy industry is booming, the film laminating of rolled solar collector strips is a key production link, and its quality and efficiency have a significant impact on the performance and cost of solar products. By laminating the surface of the collector strips with film, the friction damage to the strip surface during roll transportation can be effectively reduced. However, the existing roll solar collector strip laminating machines have some problems in actual application. In terms of film laminating quality, when the film and the strip are laminated, due to improper film tension control, the film is prone to loosening or being too tight when attached, which can easily lead to bubbles when laminating. In addition, when laminating, in order to fully cover the strip, the width of the film is generally wider than the strip, so that after laminating, there will be residual edges on both sides of the strip, which can easily lead to subsequent peeling of the film and the strip. In this regard, a roll solar collector strip laminating machine is proposed. Summary of the Invention

[0018] Furthermore, a plurality of brushes are fixedly connected to the outer wall of the deflection wheel 443 .

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Through the setting of the defoaming mechanism and the edge removal mechanism, the film on the film roll passes around the unwinding roller and the pressing roller in turn. Through the setting of the texture on the unwinding roller, the film is rotated to unfold the film to both sides. Through the setting of the pressing roller, the film is pressed down on the surface of the strip. Through the setting of the guide roller 1 and the drive motor 1, the strip is guided and released to the surface of the conveyor belt. Through the setting of the defoaming mechanism, hot liquid is passed into the defoaming mechanism so that it contacts the surface of the film, heats the film, increases the flexibility and ductility of the film, makes the film and the strip fit better, reduces bubbles between the strip and the film and wrinkles of the film, and removes the excess film on both sides of the strip through the edge removal mechanism.

[0021] 2. The setting of the capsule facilitates the large-area lamination between the capsule and the film surface. At the same time, by passing hot liquid into the capsule, the capsule heats the film, making the film softer. The lamination and extrusion of the capsule improve the adhesion between the film and the strip. The spindle-shaped setting of the capsule makes the outer contour of the lamination surface elliptical when the capsule and the film are extruded and laminated. As a result, when the capsule is squeezed on the film, the bubbles are discharged from the middle to both sides, thereby improving the lamination effect on the strip.

[0022] 3. Through the setting of the edge removal mechanism, the strip is clamped and limited by two clamping rods to prevent the strip from deviating to both sides. Through the flanging module, the second driving motor drives the deflection wheel to rotate. The deflection wheel drives the outward deflection to sweep out and unfold the film flipped under the strip, so as to prevent the film from being rolled under the drive when the strip moves to the positioning roller, thereby facilitating the cutting of the film by the cutting module. The positioning roller adsorbs and limits the strip, and the cutting module is used to accurately cut off the excess film on the edge of the strip. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1 to 4, In an embodiment of the present invention, a roll solar thermal collector strip film laminating machine includes a conveyor frame 100, an unwinding mechanism 200, a defoaming mechanism 300 and an edge removing mechanism 400. A conveyor belt 110 is installed on the conveyor frame 100 for transmission. A driving motor 140 for driving the conveyor belt 110 is installed at one end of the conveyor frame 100. The unwinding mechanism 200 is installed in the middle position of the conveyor frame 100. The unwinding mechanism 200 is used to unwind the film and attach it to the thermal collector sheet.

A limiting module 430 and a flanging module 440 are installed on the second support frame 410. Two positioning rollers 450 are installed at the top of the second support frame 410. The positioning rollers 450 are used to adsorb and fix the strip. A space is set between the two positioning rollers 450. Two cutting modules 460, the cutting module 460 is used to cut the film, the guide roller 2 420 is rotatably installed on one side of the support frame 2 410, and the guide roller 3 470 is rotatably installed on the other side of the support frame 2 410. The defoaming mechanism 300 is set between the unwinding mechanism 200 and the edge removal mechanism 400. The defoaming mechanism 300 is installed on the conveying frame 100. The defoaming mechanism 300 is used to iron the film. The other end of the conveying frame 100 is rotatably installed with the lower pressure roller 120 and The guide roller 130, the lower pressure roller 120 and the guide roller 130 are used to guide the strip. The unwinding mechanism 200 includes a support frame 210, which is fixedly installed between the support frame 210 and the conveying frame 100. The top of the unwinding mechanism 200 is rotatably installed with a film rolling roller 220, the middle position of the support frame 210 is rotatably installed with an unfolding roller 230, and the bottom end of the support frame 210 is rotatably installed with a pressing roller 240. The unfolding roller 230 is provided with spiral patterns extending to both ends.

[0035] Specifically, the film on the film winding roller 220 passes around the unwinding roller 230 and the pressing roller 240 in turn, and is rotated to unfold the film to both sides through the pattern setting on the unwinding roller 230. The film is pressed down on the surface of the strip through the setting of the pressing roller 240. The strip is guided and released to the surface of the conveyor belt 110 through the setting of the guide roller 130 and the drive motor 140. Hot liquid is passed into the interior of the defoaming mechanism 300, so that it contacts the surface of the film, heats the film, increases the flexibility and ductility of the film, makes the film fit better with the strip, reduces bubbles between the strip and the film and wrinkles of the film, and removes the excess film on both sides of the strip through the edge removal mechanism 400.

[0036] Example 1

[0037] like Figures 4 to 6As shown, in this embodiment, the defoaming mechanism 300 includes two mounting seats 310, which are fixedly mounted on the conveying frame 100, and a defoaming roller 330 is rotatably mounted between the two mounting seats 310. An interface pipe 320 is installed on the mounting seat 310, and the interface pipe 320 is connected to the defoaming roller 330. The defoaming roller 330 includes a hollow tube 331, which is rotatably connected to the mounting seat 310. A capsule 332 is installed on the hollow tube 331, and a partition plate 333 is fixedly connected to the middle position of the interior of the hollow tube 331. Through holes are provided on the side walls at both ends of the hollow tube 331, and the capsule 332 is spindle-shaped. The interface pipe 320 is used to connect with an external hot liquid source.

[0038] In this embodiment, the flexible setting of the capsule 332 facilitates the large-area adhesion of the capsule 332 to the surface of the film. At the same time, by passing hot liquid into the capsule 332, the capsule 332 heats the film, making the film softer. The adhesion and extrusion of the capsule 332 improve the adhesion between the film and the strip. The spindle-shaped setting of the capsule 332 allows the outer contour of the adhesion surface to be elliptical when the capsule 332 is squeezed and adhered to the film. Therefore, when the capsule 332 squeezes the film, the bubbles are discharged from the middle to both sides, thereby improving the coating effect on the strip.

[0039] Example 2

[0040] like Figures 4 to 9As shown, in this embodiment, the positioning roller 450 includes two mounting seats 451, which are fixedly connected to the support frame 410, and a roller rod 452 is fixedly connected between the two mounting seats 451. An open portion 453 is provided on one side of the roller rod 452, and a mesh sleeve 454 is rotatably sleeved on the roller rod 452. One end of the roller rod 452 is used to connect to an external negative pressure air source. The cutting module 460 includes a fixed seat 461, which is fixedly installed between the fixed seat 461 and the support frame 410. The top of the fixed seat 461 is slidably sleeved with an insertion rod 463, one end of the insertion rod 463 is rotatably connected to the support rod 464, and one end of the insertion rod 463 is fixedly installed with a vertical rod 465, and a slide 466 is slidably sleeved on the vertical rod 465. A circular knife 467 is rotatably installed on one end of the slide 466, and the top of the vertical rod 465 is connected to the slide 4 66 is fixedly connected with an extrusion spring 468, and the top of the fixed seat 461 is rotatably connected with a screw 462, and one end of the insertion rod 463 is provided with a threaded hole, and the screw 462 and the insertion rod 463 are screwed together. The limiting module 430 includes a cross frame 1 431, which is fixedly installed between the cross frame 1 431 and the support frame 2 410, and a two-way screw rod 432 is rotatably installed on the cross frame 1 431, and clamping rods 433 are slidably installed at both ends of the cross frame 1 431, and one end of the clamping rod 433 is screwed together with the two-way screw rod 432. The flanging module 440 includes a cross frame 2 441, which is fixedly installed on the support frame 2 410, and a driving motor 2 442 is fixedly connected to the output end of the driving motor 2 442, and a deflection wheel 443 is fixedly installed, and a plurality of brushes are fixedly connected to the outer wall of the deflection wheel 443.

[0041] During specific implementation, after the strip passes under the second guide roller 420, it passes over the two positioning rollers 450, and the strip is adsorbed and fixed by the two positioning rollers 450. The two-way screw rod 432 is manually rotated to adjust the distance between the two clamping rods 433. The strip is clamped and limited by the two clamping rods 433 to prevent the strip from deviating to both sides. Since the distance between the two clamping rods 433 is limited according to the width of the strip, the two sides of the film will be deflected by the clamping rods 433. Through the setting of the flanging module 440, the driving motor 2 442 drives the deflection wheel 443 to rotate, and the deflection wheel 443 drives the outward deflection to sweep the film flipped under the strip outward and unfold it to avoid When the strip moves onto the positioning roller 450, the film is rolled up to the bottom of the drive, thereby facilitating the cutting of the film by the cutting module 460. Through the setting of the positioning roller 450, the external negative pressure air source provides negative pressure to the roller rod 452. Through the setting of the opening part 453, the adsorption position of the mesh sleeve 454 on the strip coincides with the bonding position of the strip. Through the rotation setting of the mesh sleeve 454, the transmission of the strip is facilitated. Through the setting of the cutting module 460, the screw 462 is manually rotated, and the screw 462 drives the insertion rod 463 and the support rod 464 to move sideways, and the position of the circular knife 467 is adjusted so that the circular knife 467 is aligned with the edge of the strip, thereby realizing the cutting of excess film on the edge of the strip.
