[0002] When manufacturing photovoltaic coated clothing, the photovoltaic coating film needs to be pressed onto the fabric used to make the clothes, and the photovoltaic coating needs to be adhered to the surface of the fabric to achieve lamination. Before fabric lamination, if there are wrinkles or unevenness on the fabric surface, the photovoltaic film cannot be evenly adhered, resulting in local stress concentration or loose adhesion, which affects the effect of film lamination. Therefore, the fabric needs to be smoothed before lamination.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 5 The present invention provides a technical solution: a fabric processing device for laminating a thin-film photovoltaic coating, comprising a frame 1, a top of the frame 1 is fixedly connected to an electric telescopic rod 2, an output shaft of the electric telescopic rod 2 is fixedly connected to a vertical rod 3, a bottom of the vertical rod 3 is fixedly connected to a laminating member 4 for laminating the thin-film photovoltaic coating on the surface of the fabric, a smoothing component 5 for smoothing the fabric is arranged below the electric telescopic rod 2, the smoothing component 5 comprises a lifting sleeve 51 slidably connected to the outside of the vertical rod 3, both sides of the front and rear ends of the lifting sleeve 51 are rotatably connected to curved pipes 52, a smoothing cylinder 53 is rotatably connected between the two opposite curved pipes 52, and a torsion spring 54 is fixedly connected between the top of the curved pipe 52 and the lifting sleeve 51.

[0021] By adopting the above-mentioned technical scheme, when preparing for use, the fabric to be pasted with the photovoltaic coating film is laid flat on the inner bottom of the frame 1, and the laminating member 4 can laminate the photovoltaic coating film on the surface of the fabric by hot pressing, and the bottom of the laminating member 4 can be provided with an adsorption structure of the photovoltaic coating film, so that the film can be placed under the laminating member 4 before lamination. The technology of hot pressing the laminating member 4 is a mature existing technology and will not be elaborated in detail.

[0022] When the film is applied, the output shaft of the electric telescopic rod 2 is extended to make the vertical rod 3 move downward, so that the laminating member 4 moves downward with the film, so that the film can be applied to the surface of the fabric, and the laminating member 4 completes the application of the film.

[0023] While the film is being applied, as the output shaft of the electric telescopic rod 2 extends, the lifting sleeve 51 can move downward, thereby causing the bending pipe 52 and the smoothing cylinder 53 to move downward. It should be noted that in the initial state, the smoothing cylinder 53 is located below the laminating member 4, and under the elastic force of the torsion spring 54, the two smoothing cylinders 53 are pressed against each other. When the output shaft of the electric telescopic rod 2 is extended, the smoothing cylinder 53 first contacts the surface of the fabric, and then the output shaft of the electric telescopic rod 2 continues to extend. When the laminating member 4 moves downward, the smoothing cylinder 53 At the same time, the angles of the two bent tubes 52 change, and the torsion spring 54 is deformed, so that the smoothing cylinder 53 rolls in both directions against the chemical fiber fabric, thereby smoothing the fabric before lamination, until the lamination member 4 laminates the film onto the surface of the fabric. This design allows the smoothing cylinder 53 to continue to provide smoothing force to the fabric when the film is laminated, thereby reducing the rebound and wrinkling of the chemical fiber fabric, improving the flatness of the chemical fiber fabric when laminating the film, and thereby improving the effect of laminating the photovoltaic coating film on the fabric.

[0024] It should be noted that when the torsion spring 54 is deformed, the torsion can be transmitted to the position of the smoothing cylinder 53 through the curved tube 52, thereby providing pressure on the fabric during smoothing.

[0025] Specifically, Figures 1 to 5 As shown, the smoothing assembly 5 also includes a fixed plate 55 fixedly connected to the outer wall of the vertical rod 3 and located above the lifting sleeve 51, a first spring 56 is fixedly connected between the bottom of the fixed plate 55 and the lifting sleeve 51, lifting plates 57 are fixedly connected to the bottom of both sides of the lifting sleeve 51, and blocking plates 58 are fixedly connected to both sides of the inner rear end of the frame 1, and the elastic force of the first spring 56 is greater than the elastic force of the torsion spring 54.

[0026] By adopting the above technical solution, when the output shaft of the electric telescopic rod 2 is extended, the angle of the curved tube 52 is changed, so that the smoothing cylinder 53 is close to the chemical fiber fabric and rolls in both directions. When the bottom of the laminating member 4 is about to contact the fabric, the bottom of the lifting plate 57 contacts the obstruction plate 58. Under the blocking effect of the obstruction plate 58, the lifting plate 57 cannot move downward, so that the lifting sleeve 51 and the curved tube 52 no longer move downward. As the output shaft of the electric telescopic rod 2 continues to extend, the distance between the fixed plate 55 and the lifting sleeve 51 becomes smaller, and the first spring 56 is compressed. Under the elastic force of the first spring 56, the bottom of the lifting plate 57 is always close to the obstruction plate 58, ensuring that the curved tube 52 maintains its original angle and keeps smoothing the fabric.

[0027] Such a design can stop the smoothing cylinder 53 used for smoothing from rolling before the film is applied. At this time, the smoothing cylinder 53 can fix the fabric to ensure the stability of the fabric shape, avoid affecting the flatness of the fabric when the film is applied, and further improve the effect of the photovoltaic coating film application layer on the fabric.

[0028] Specifically, Figures 2 to 6 As shown, auxiliary components 6 are provided at both the front and rear ends of the interior of the frame 1, and the auxiliary component 6 includes a moving frame 61 slidably connected to the side close to the two obstruction plates 58, a trapezoidal groove 62 is opened inside the moving frame 61, and the curved pipe 52 passes through the inside of the trapezoidal groove 62, and a curved frame 63 is fixedly connected to the side of the moving frame 61 away from the laminated member 4, and a sliding sleeve 64 is slidably connected to the bottom of the curved frame 63, and an auxiliary frame 65 is fixedly connected to the bottom of the sliding sleeve 64, and a second spring 69 is fixedly connected between the moving frame 61 and the obstruction plate 58, and a rotating cylinder 66 is rotatably connected to the bottom of the auxiliary frame 65. The auxiliary component 6 also includes a limiting rod 67 fixedly connected to the front and rear ends of the bottom of the inner side of the frame 1, and the end of the limiting rod 67 close to the auxiliary frame 65 and the auxiliary frame 65 close to the limiting rod 67 are both inclined, and a U-shaped spring piece 68 is fixedly connected between the curved frame 63 and the sliding sleeve 64.

[0029] By adopting the above technical solution, the side length of the trapezoidal groove 62 close to the laminating member 4 is greater than the side length of the trapezoidal groove 62 away from the laminating member 4. In the initial state, under the elastic force of the second spring 69, the two curved tubes 52 in the same trapezoidal groove 62 are located in the trapezoidal groove 62 away from the laminating member 4, and under the elastic force of the U-shaped spring piece 68, there is a gap between the bottom of the rotating cylinder 66 and the inner bottom of the frame 1, so that the fabric can be laid flat on the inner bottom of the frame 1 during the preparation stage. When the output shaft of the electric telescopic rod 2 is extended to offset the angle of the curved tube 52, the two curved tubes 52 gradually move away from each other and squeeze the inclined edge inside the trapezoidal groove 62. When the two curved tubes 52 are squeezed toward both sides from the narrower bottom edge of the trapezoidal groove 62, the contact point between the curved tube 52 and the inner wall of the trapezoidal groove 62 is not perpendicular to the hypotenuse of the trapezoidal groove 62, but forms a certain angle. According to the force decomposition principle, the extrusion force applied by the curved tube 52 can be decomposed into a component force perpendicular to the side wall of the trapezoidal groove 62, which is used for the deformation or movement trend of the movable frame 61, and a component force parallel to the bottom edge of the frame. Due to the angle of the contact point, the component force will push the movable frame 61 to move along the bottom edge direction, that is, the front and back direction, so that the movable frame 61 moves forward and backward in the direction away from the laminating member 4, thereby causing the curved frame 63, the sliding sleeve 64, and the auxiliary frame 65 to move in the direction away from the laminating member 4.

[0030] The principle that the curved pipe 52 squeezes the inclined edge of the trapezoidal groove 62 to move the movable frame 61 utilizes the common wedge effect and is a mature prior art.

[0031] When the auxiliary frame 65 moves in the direction away from the lamination piece 4, relative movement occurs between the auxiliary frame 65 and the limiting rod 67, and under the action of the inclination of the limiting rod 67 and the auxiliary frame 65 near each other, when the auxiliary frame 65 moves in the direction away from the lamination piece 4, the auxiliary frame 65 and the sliding sleeve 64 will move downward accordingly. When the limiting rod 67 moves to the top of the auxiliary frame 65, the bottom of the rotating cylinder 66 is in close contact with the fabric. At this time, the bent tube 52 continues to rotate, so that the auxiliary frame 65 and the rotating cylinder 66 provide smoothing force to the fabric in the front and rear directions. Applying the smoothing force in the front and rear directions can balance the stress distribution inside the fabric and reduce the deformation caused by force in a single direction, thereby further improving the flatness of the fabric after being smoothed, and further improving the effect of the photovoltaic coating film laminating on the fabric.

[0032] Specifically, Figures 2 to 4 and Figures 7 and 8As shown, the interior and top of the frame 1 are jointly provided with a dust collecting assembly 7 for sucking dust off the surface of the fabric, the dust collecting assembly 7 includes a ventilation groove 71 provided inside the lifting sleeve 51, the top of the curved pipe 52 is inserted into the ventilation groove 71, the dust collecting assembly 7 also includes a suction hole 73 provided on the surface of the smoothing cylinder 53, the dust collecting assembly 7 also includes an air cylinder 74 fixedly connected to the front end of the top of the frame 1, the interior of the air cylinder 74 is movably connected with a piston plate 75, the outer side of the piston plate 75 is in contact with the inner wall of the air cylinder 74, the bottom of the piston plate 75 is fixedly connected with a connecting frame 76, and the bottom of the connecting frame 76 is fixedly connected to the fixed plate 55. An air intake pipe 77 is fixedly connected between the top of the air cylinder 74 and the ventilation groove 71, and a straight pipe 78 is fixedly connected to the inside of the piston plate 75. Check valves 72 are installed inside the air intake pipe 77 and the straight pipe 78. A section of hose is set in the middle part of the air intake pipe 77 so as not to affect the movement of the lifting sleeve 51. The principle and installation method of the check valve 72 are mature existing technologies and will not be elaborated on. The check valve 72 in the air intake pipe 77 only allows the gas in the air intake pipe 77 to flow from the ventilation groove 71 to the ventilation cylinder 74, and the check valve 72 in the straight pipe 78 only allows the gas in the straight pipe 78 to flow from top to bottom.

[0033] By adopting the above technical solution, when smoothing and film coating are performed, as the output shaft of the electric telescopic rod 2 is extended, the fixing plate 55 moves downward with the connecting frame 76, thereby causing the piston plate 75 to move downward. At this time, negative pressure is generated inside the air cylinder 74 and above the piston plate 75, so that the gas in the ventilation groove 71 and the curved pipe 52 enters the inside of the air cylinder 74 and above the piston plate 75 through the suction pipe 77. In this process, the smoothing cylinder 53 can inhale air through the suction hole 73, so as to absorb impurities and dust on the fabric, thereby preventing the dust and debris on the fabric from affecting the effect of the lamination between the film and the fabric when the film is coated.

[0034] When the output shaft of the electric telescopic rod 2 contracts, the fixed plate 55 moves upward with the connecting frame 76 and the piston plate 75 , and the gas that enters the interior of the gas cylinder 74 and is located above the piston plate 75 is discharged from the straight pipe 78 .

[0035] It should be noted that a device for collecting and filtering dust can be installed inside the air cylinder 74, including but not limited to a collection box installed at the bottom of the straight tube 78, and a filter is fixedly connected to the bottom of the collection box. After the dust absorbed from the surface of the fabric enters the interior of the air cylinder 74 with the air and is located above the piston plate 75, the output shaft of the electric telescopic rod 2 contracts, and the dust enters the collection box with the air and remains in the collection box under the action of the filter.

[0036] It should be noted that before the fabric to be pasted with the photovoltaic coating film is laid flat on the inner bottom of the frame 1, the fabric may be slightly shaken to make it smooth so that less dust is absorbed on the surface of the fabric.

[0037] It should be noted that the diameter of the air cylinder 74 is set large enough to ensure sufficient air volume for dust collection.

[0038] Specifically, Figures 2 to 4 and Figures 6 to 10 As shown, an air-blocking assembly 8 is provided inside the smoothing cylinder 53, and the air-blocking assembly 8 includes a cylinder 81 fixedly connected between the bottoms of two opposite curved pipes 52 and located inside the smoothing cylinder 53, and an empty groove 82 is opened at the bottom position of the cylinder 81, and an air-blocking strip 83 is fixedly connected to the inner wall of the smoothing cylinder 53 in a circular arrangement, and the air-blocking strip 83 is made of rubber material, and the side of the air-blocking strip 83 away from the smoothing cylinder 53 is attached to the outer wall of the cylinder 81.

[0039] By adopting the above technical scheme, the curved pipe 52 is connected with the cylinder 81. In the initial state where the curved pipe 52 has not rotated, the empty groove 82 is located at the bottom of the cylinder 81 and is slightly inclined. Since the rotation angle of the curved pipe 52 is limited, when the smoothing action is completed, the empty groove 82 is still close to the bottom. The design of multiple air-blocking strips 83 can divide the interior of the smoothing cylinder 53 into multiple separate spaces. During smoothing, as the smoothing cylinder 53 moves and the interior of the curved pipe 52 is inhaled due to negative pressure, only the space located at the empty groove 82 among the multiple separate spaces in the smoothing cylinder 53 is connected with the interior of the cylinder 81. Since the empty groove 82 is close to the bottom, only the suction holes 73 close to the bottom can be inhaled. With this design, only the suction holes 73 close to the fabric below can be inhaled, and the suction effect generated by the negative pressure is concentrated at the bottom, thereby improving the suction effect.

[0040] It should be noted that during the smoothing process, the smoothing cylinder 53 rotates, and the smoothing cylinder 53 will rotate relative to the cylinder 81, so that the inner side of the air-blocking strip 83 will slide on the surface of the cylinder 81. During this process, static electricity will be generated under the action of friction. The static electricity can absorb dust to a certain extent, reduce the possibility of dust falling from the suction hole 73, further improve the dust absorption effect, and then improve the effect of the lamination between the film and the fabric.

[0041] It should be noted that, during the smoothing process, the smoothing cylinders 53 on both sides generate tension in the fabric. If the friction coefficient between the smoothing cylinder 53 and the bent tube 52 bracket is small, the tension will cause the smoothing cylinder 53 to roll during smoothing, resulting in a certain rebound of the fabric, thereby affecting the smoothing effect. Multiple air-blocking strips 83 will make the friction coefficient between the smoothing cylinder 53 and the cylinder 81 bracket larger. When the smoothing cylinder 53 used for smoothing stops rolling before the film is applied, the smoothing cylinder 53 fixes the fabric, avoiding the influence of tension on the chemical fiber fabric to rebound, thereby further improving the smoothing effect, and then improving the effect of the lamination between the film and the fabric.

[0042] Working principle: In the preparation stage, the fabric to be pasted with the photovoltaic coating film is laid flat on the inner bottom of the frame 1.

[0043] During smoothing, the output shaft of the electric telescopic rod 2 is extended, and the lifting sleeve 51 moves downward accordingly, and the curved tube 52 and the smoothing cylinder 53 move downward accordingly. When the output shaft of the electric telescopic rod 2 is extended, the smoothing cylinder 53 first contacts the surface of the fabric, and then the output shaft of the electric telescopic rod 2 continues to extend. While the laminating component 4 moves downward, the angles of the two curved tubes 52 change, and the torsion spring 54 is deformed, so that the smoothing cylinder 53 rolls in both directions close to the chemical fiber fabric, thereby smoothing the fabric before lamination, until the laminating component 4 applies the film lamination to the surface of the fabric, so that when the film is applied, the smoothing cylinder 53 can continue to provide smoothing force to the fabric.

[0044] In the process of smoothing the fabric, the bottom of the lifting plate 57 contacts the obstruction plate 58. Under the blocking effect of the obstruction plate 58, the lifting plate 57 cannot move downward, so that the lifting sleeve 51 and the curved tube 52 no longer move downward. As the output shaft of the electric telescopic rod 2 continues to extend, the distance between the fixed plate 55 and the lifting sleeve 51 becomes smaller, and the first spring 56 is compressed. Under the elastic force of the first spring 56, the bottom of the lifting plate 57 is always close to the obstruction plate 58 to ensure that the curved tube 52 maintains its original angle. Before the film is applied, the smoothing cylinder 53 used for smoothing can stop rolling. At this time, the smoothing cylinder 53 can fix the fabric to ensure that the shape of the fabric is stable and avoid affecting the flatness of the fabric when the film is applied.

[0045] When the output shaft of the electric telescopic rod 2 is extended to cause the angle of the bent tube 52 to deviate, the two bent tubes 52 gradually move away from each other and squeeze the inclined edge inside the trapezoidal groove 62, so that the moving frame 61 moves away from the laminating member 4, thereby causing the bent frame 63, the sliding sleeve 64, and the auxiliary frame 65 to move away from the laminating member 4. When the auxiliary frame 65 moves away from the laminating member 4, relative movement occurs between the auxiliary frame 65 and the limiting rod 67, and the limiting rod 67 and the auxiliary frame 65 are inclined at the position where the limiting rod 67 and the auxiliary frame 65 are close to each other. When the auxiliary frame 65 moves away from the laminating member 4, the auxiliary frame 65 and the sliding sleeve 64 will move downward accordingly. When the limiting rod 67 moves to the top of the auxiliary frame 65, the bottom of the rotating cylinder 66 is close to the fabric. At this time, the curved tube 52 continues to rotate, so that the auxiliary frame 65 and the rotating cylinder 66 provide smoothing force to the fabric in the front and rear directions. Applying the smoothing force in the front and rear directions can balance the stress distribution inside the fabric and reduce the deformation caused by force in a single direction, thereby further improving the flatness of the fabric after being smoothed.

[0046] As the output shaft of the electric telescopic rod 2 extends, the fixing plate 55 moves downward with the connecting frame 76, thereby causing the piston plate 75 to move downward. At this time, negative pressure is generated inside the air cylinder 74 and above the piston plate 75, so that the gas in the ventilation groove 71 and the curved pipe 52 enters the inside of the air cylinder 74 and above the piston plate 75 through the suction pipe 77. In this process, the smoothing cylinder 53 can inhale air through the suction hole 73 to absorb impurities and dust on the fabric.

[0047] During smoothing, as the smoothing cylinder 53 and the interior of the curved pipe 52 are inhaled due to negative pressure, among the multiple separate spaces in the smoothing cylinder 53, only the space located at the empty groove 82 is connected to the interior of the cylinder 81, and since the empty groove 82 is close to the bottom, only the suction holes 73 close to the bottom can inhale. With this design, only the suction holes 73 close to the fabric below can inhale, and the suction effect caused by the negative pressure is concentrated at the bottom, thereby improving the suction effect.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
