Description

Technical Field

[0001] The present invention relates to the technical field of film laminating machines, and specifically to a roll solar heat collector strip film laminating machine. Background Art

[0002] At present, with the booming development of the solar energy industry, film laminating of roll solar heat 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 a film on the surface of the heat collector strip, the frictional damage to the strip surface during coiling and transportation can be effectively reduced. However, there are some problems in the actual application of existing roll solar heat collector strip film laminating machines. In terms of film laminating quality, when the film material is bonded to the strip, due to improper tension control of the film material, the film material is prone to looseness or tightness during attachment, which will cause bubbles to easily appear during film laminating. And when bonding, in order to fully cover the strip, the width of the film is generally wider than that of the strip, so that after film laminating, there will still be margins on both sides of the strip, and the margins are prone to cause subsequent peeling of the film from the strip. For this reason, a roll solar heat collector strip film laminating machine is proposed. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1.

Through the texture setting on the unwinding roller, the film is rotated to unfold 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 introduced into the defoaming mechanism so as to contact the surface of the film, heat the film, increase the flexibility and ductility of the film, make the film and the strip fit better, reduce the bubbles between the strip and the film and the wrinkles of the film, and cut off the excess film parts on both sides of the strip through the edge removal mechanism; 2. The setting of the capsule facilitates the large-area bonding of 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 bonding and extrusion of the capsule improves the adhesion between the film and the strip. The spindle-shaped setting of the capsule makes the outer contour of the bonding surface elliptical when the capsule and the film are extruded and bonded. Therefore, when the capsule is extruded on the film, the bubbles are discharged from the middle to both sides, thereby improving the film coating effect on the strip; 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 up 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

[0019] Specifically, the film on the film winding roller 220 passes around the unwinding roller 230 and the pressing roller 240 in turn, and the film is rotated to unfold to both sides through the texture setting on the unwinding roller 230, and the film is pressed down on the surface of the strip through the setting of the pressing roller 240, and 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, and the defoaming mechanism 300 is set, and 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 the bubbles between the strip and the film and the wrinkles of the film, and removes the excess film parts on both sides of the strip through the edge removal mechanism 400.

[0020] Embodiment 1

[0021] like Figures 4 to 6As shown in the figure, in this embodiment, the defoaming mechanism 300 includes two first mounting seats 310 which are fixedly mounted on the conveying frame 100. A defoaming roller 330 is rotatably mounted between the two first mounting seats 310. An interface pipe 320 is mounted on the first mounting seat 310. The interface pipe 320 is communicated with the defoaming roller 330. The defoaming roller 330 includes a hollow pipe 331 which is rotatably connected to the first mounting seat 310. A bladder 332 is mounted on the hollow pipe 331. A partition plate 333 is fixedly connected to the middle position inside the hollow pipe 331. Through holes are formed in the side walls at both ends of the hollow pipe 331. The bladder 332 is spindle-shaped. The interface pipe 320 is used to dock with an external hot liquid source.

[0022] In this embodiment, due to the flexible setting of the bladder 332, it is convenient for the bladder 332 to be in large-area contact with the surface of the film. At the same time, by introducing hot liquid into the bladder 332, the bladder 332 heats the film, making the film softer. With the fitting and extrusion of the bladder 332, the adhesion between the film and the strip is improved. Due to the spindle-shaped setting of the bladder 332, when the bladder 332 is in extrusion contact with the film, the outer contour of the contact surface is oval. Therefore, when the bladder 332 extrudes the film, the bubbles are discharged from the middle to both sides, improving the film covering effect on the strip.

[0023] Embodiment Two

[0024] As Figures 4 to 9As shown, in this embodiment, the positioning roller 450 includes two second mounting seats 451. The second mounting seats 451 are fixedly connected to the second support frame 410. A roller rod 452 is fixedly connected between the two second mounting seats 451. An open portion 453 is formed on one side of the roller rod 452. A mesh sleeve 454 is rotatably sleeved on the roller rod 452. One end of the roller rod 452 is used to be connected to an external negative pressure air source. The cutting module 460 includes a fixed seat 461. The fixed seat 461 is fixedly installed on the second support frame 410. A plug rod 463 is slidably sleeved on the top end of the fixed seat 461. One end of the plug rod 463 is rotatably connected to a support rod 464. A vertical rod 465 is fixedly installed at one end of the plug rod 463. A sliding frame 466 is slidably sleeved on the vertical rod 465. A circular knife 467 is rotatably installed at one end of the sliding frame 466. A compression spring 468 is fixedly connected between the top end of the vertical rod 465 and the sliding frame 466. A screw rod 462 is rotatably connected to the top end of the fixed seat 461. A threaded hole is formed at one end of the plug rod 463. The screw rod 462 is in threaded connection with the plug rod 463. The limiting module 430 includes a first cross frame 431. The first cross frame 431 is fixedly installed on the second support frame 410. A bidirectional lead screw 432 is rotatably installed on the first cross frame 431. Clamping rods 433 are slidably installed at both ends of the first cross frame 431. One end of the clamping rod 433 is in threaded connection with the bidirectional lead screw 432. The flanging module 440 includes a second cross frame 441. The second cross frame 441 is fixedly installed on the second support frame 410. Driving motors two 442 are fixedly connected to both ends of the second cross frame 441. A deflection wheel 443 is fixedly installed at the output end of the driving motor two 442. A plurality of brushes are fixedly connected to the outer side wall of the deflection wheel 443.

[0025] During specific implementation, after the strip bypasses below the second guiding roller 420, it bypasses above the two positioning rollers 450. The two positioning rollers 450 adsorb and fix the strip. Manually rotate the bidirectional lead screw 432 to adjust the distance between the two clamping rods 433, and clamp and limit the strip through the two clamping rods 433 to prevent the strip from shifting to both sides. Since the distance between the two clamping rods 433 is limited according to the width of the strip, both sides of the film will be lifted and deflected by the clamping rods 433. Through the setting of the flanging module 440, the driving motor two 442 drives the deflection wheel 443 to rotate, and the deflection wheel 443 drives the film that has been deflected outwards and turned below the strip to be swept outwards and unfolded, preventing the film from being wound below the strip when the strip moves onto the positioning roller 450, thus facilitating the cutting of the film by the cutting module 460. Through the setting of the positioning roller 450, an external negative pressure air source provides negative pressure into 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 fitting position of the strip. Through the rotational setting of the mesh sleeve 454, it is convenient for the transmission of the strip. Through the setting of the cutting module 460, manually rotate the screw rod 462, and the screw rod 462 drives the insertion rod 463 and the support rod 464 to move laterally to adjust the position of the circular knife 467 so that the circular knife 467 is aligned with the edge of the strip, thereby realizing the cutting of the redundant film at the edge of the strip.

[0026] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
