Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic adhesive film cutting, in particular to a fast cutting device for photovoltaic adhesive films. Background Art

[0002] Photovoltaic film usually uses EVA film, which is a thermosetting and sticky film used to be placed in the middle of laminated glass. Due to the advantages of EVA film in adhesion, durability, optical properties, etc., it is more and more widely used in current components and various optical products. EVA film needs to be cut into specified sizes before use. Currently, most of them are cut by hand, which has very low efficiency and certain safety risks.

[0003] Regarding the photovoltaic film cutting device, it was found through searching that the national publication number CN207155899U discloses "an EVA film cutting mechanism for photovoltaic modules". When in use, the EVA film is unwound through the unwinding mechanism, and the EVA film is pulled to the conveying mechanism and conveyed under the conveying of the conveying mechanism. During the conveying process, the cutting knife cuts the EVA film under the drive of the cylinder. The cutting efficiency is high and there is no safety hazard. However, in the actual use process, there are still some problems. The film will generate friction during the conveying process, and the friction will cause the film Static electricity is generated on the surface, causing the film to be adsorbed on the conveying mechanism. In addition, the film is thin and difficult to take down, and it is easy to damage the film when taking it down, which brings inconvenience to subsequent operations and affects work efficiency. At the same time, the film will be cut into the required size according to needs before use, so the width of the film will also be cut. Waste will be generated in the trimming process. This part of the waste is usually directly put into the frame for easy recycling. Due to the long length of the waste, it is relatively chaotic and disorderly when it falls directly into the frame, and the space occupancy rate is high, which is not conducive to storage and brings inconvenience to recycling.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0025] The embodiment of the present application provides a rapid cutting device for photovoltaic film, which can realize the removal of the cut film through the blanking component without manual removal, thereby reducing the difficulty of blanking and collecting, making it simpler and more convenient, improving work efficiency, and avoiding damage to the film during manual removal, reducing the scrap rate, and improving production quality.

[0026] The photovoltaic film rapid cutting device is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0027] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example 1

[0028] See also Figure 1-8 In this embodiment, a rapid cutting device for photovoltaic film is provided, including: a support frame 1, two feeding belts 11 are arranged inside the support frame 1, a unloading belt 12 is arranged on the side of the support frame 1 away from the two feeding belts 11, a platform 13 is arranged between the two feeding belts 11, two pressing rollers 14 are arranged on the support frame 1, a loading frame 15 is fixedly connected to one side of the support frame 1, a unloading component, the unloading component is arranged on one side of the support frame 1, and is used to remove the cut photovoltaic film from the unloading belt 12, and a recycling component is arranged on the support frame 1, and is used to recycle the waste generated by cutting. Example 2

[0029] On the basis of Example 1, the unloading component includes: an unloading platform 2 connected to the side of the support frame 1 away from the loading frame 15, a baffle 21 is provided on the unloading platform 2, and a slide groove 22 is opened on the upper surface of the unloading platform 2, a threaded block 23 is slidably connected inside the slide groove 22, the top of the threaded block 23 is connected to the bottom of the baffle 21, a threaded screw 24 is rotatably connected inside the slide groove 22, the threaded block 23 is threadedly connected to the outside of the threaded screw 24, one end of the threaded screw 24 passes through the slide groove 22 and extends to the outside and is connected to a handwheel 25, a mounting frame 26 is fixedly installed at the top of the support frame 1 near the unloading platform 2, and an ion blower 27 is fixedly installed on the top of the mounting frame 26.

[0030] When the film is cut, friction will generate static electricity during the feeding process, causing the film to be adsorbed on the feeding belt 12. Since the film is thin, it is difficult to take it off after being adsorbed on the feeding belt 12. Therefore, the film is transported to one side along with the feeding belt 12, and the ion fan 27 is started through the control panel. After the ion fan 27 is started, an air flow with positive and negative ions will be blown out. When the film is lowered through the ion fan 27, it will be adsorbed and neutralized with the charge carried by the film on the feeding belt 12, eliminating the static charge on the surface of the film, thereby separating the film from the feeding belt 12, and the side of the fallen film When the film is cut, it touches the baffle 21, which blocks the film and makes it fall naturally onto the unloading table 2, so that the cut films are stacked together. The films with static electricity eliminated are also easy to take out. According to the size of the cut film, the position of the baffle 21 needs to be adjusted, and the threaded screw 24 is driven to rotate by turning the hand wheel 25. The threaded screw 24 rotates and engages with the threaded block 23, thereby driving the threaded block 23 to move. When moving, the threaded block 23 is driven to move, and then the baffle 21 is driven to move, so as to adapt to films of different sizes. Example 3

[0031] On the basis of Example 1, the recycling component includes: two changing direction rollers a3 are respectively provided on the opposite sides of the top of the support frame 1, and matching changing direction rollers b31 are respectively provided at one side position close to the two changing direction rollers a3, and a transmission roller 32 is provided near the middle position of the support frame 1. The rotating shafts at both ends of the transmission roller 32 are respectively fixedly connected with winding rollers 33, and two limit plates 34 are respectively provided on the two winding rollers 33.

[0032] When collecting the cut waste, first remove a limit plate 34, set the winding paper tube on the winding roller 33, and then install the removed limit plate 34 so that the two limit plates 34 clamp the paper tube. The cut waste passes through the top from the bottom of the change-direction roller a3 in turn, so that the waste is turned to a 90-degree state, and then passes through the bottom from the top of the change-direction roller b31, and then the waste is turned to a 180-degree state, and one end of the waste is connected to the winding paper tube. The transmission roller 32 contacts the film. When the film moves, it will drive the transmission roller 32 to rotate, and the transmission roller 32 drives the winding roller 33 to rotate, and then the waste is rolled up. The two limit plates 34 can limit the waste during the winding process to avoid uneven winding, thereby facilitating recycling.

[0034] When the width of the film needs to be cut, the fixing bolt 44 is loosened to contact the fixed slider 42, and the slider 42 is moved to slide on the two guide rods 41 to move the trimming knife 43 to a suitable distance. The film will be cut when passing the trimming knife 43.

[0035] Among them, a gantry 5 is fixedly installed on the top of the support frame 1, and two cylinders 51 are fixedly installed on the top of the gantry 5. The bottom ends of the telescopic rods of the two cylinders 51 are fixedly connected with movable cutters 52. The support frame 1 is provided with a fixed cutter 53 used in conjunction with the movable cutter 52.

[0036] The film is transported to the gantry 5 by the cooperation of the feeding belt 11 and the pressing roller 14.
