Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic equipment, in particular to a paper laying machine. Background Art

[0002] Photovoltaic glass is a special photovoltaic glass used to make solar panels. It has the characteristics of high light transmittance, low reflectivity, and high mechanical strength. Photovoltaic glass needs to be surface treated during the production process to prevent the surface of the photovoltaic glass from being contaminated or damaged. A commonly used surface treatment method is to lay a layer of paper on the surface of the photovoltaic glass to isolate moisture and impurities in the air and keep the surface of the photovoltaic glass clean and dry.

[0003] The paper laying machine is a device used to lay paper on the surface of photovoltaic glass. It is mainly used for protection and isolation during the production process of photovoltaic glass. The main function of the paper laying machine is to convey the paper to the photovoltaic glass, and cut and position it according to the size and shape of the photovoltaic glass to achieve the fit between the paper and the photovoltaic glass. The performance and accuracy of the paper laying machine directly affect the quality and production efficiency of photovoltaic glass.

[0004] On June 7, 2023, the applicant applied for three patents, namely, "Online electrostatic continuous paper laying machine and paper laying method for photovoltaic glass" disclosed by patent publication number CN 116788911A, "Paper laying device of paper laying machine" disclosed by patent publication number CN220165190U, and "Paper cutting device of paper laying machine" disclosed by patent publication number CN220222945U. These three patents disclose a paper conveying device and a paper cutting device. The main structure and working method of this scheme are to lay the isolation paper on the paper roller through a tensioning roller device, and then lay it on the glass on the conveying device from the paper laying mechanism. After the laying and covering is completed, the paper is cut off with a cutter to complete the laying process.

[0005] During the use of this solution, the applicant found that there was a technical problem that the system often needed to be shut down and waited, which affected the work efficiency. The reasons for this technical problem are as follows: 1. There is only one paper roller and its installation station on the paper laying machine. When the paper on one paper roller is used up, the machine can only be stopped for replacement, and the paper needs to be re-inserted, which affects work efficiency; 2. Since the cutting mechanism is provided by a corresponding cutter head mechanism and a paper suction mechanism, the cutter head mechanism is provided above the paper suction mechanism to cut off the paper fed by the paper conveying roller. The paper is cut off with the cooperation of the cutter head mechanism and the paper suction mechanism. The structure is also provided with a gravity roller, which is provided above the paper suction mechanism. The gravity roller paper pressing mechanism applies pressure to the paper in the following way, so as to prevent the paper from slipping or shifting during the cutting process, thereby improving the cutting accuracy and stability. However, the structure has the following disadvantages: when cutting the paper, the paper suction mechanism and the gravity roller need to work together to ensure the stability of the paper. After each cutting of the paper, the paper has to be paused, and the paper needs to be manually passed through the paper suction mechanism and the gravity roller again. Otherwise, due to the inertia of the rotation of the gravity roller, the paper is likely to warp, which is not conducive to subsequent cutting. This results in the machine having to stop once for each cutting, which greatly affects the work efficiency. Summary of the invention

The paper roll shaft 2 rotates to continuously release the paper and then introduces it into the paper cutting device 5 through the tensioning conveying roller device 3. After the paper is cut by the paper cutting device 5, it falls onto the photovoltaic glass conveying roller device 4. The paper suction mechanism 6 and the cutter head mechanism 7 are prior art, and adopt the structure disclosed in patent publication number CN116788911A, and are not described in detail in this embodiment.

[0024] The frame 1 is a rectangular frame with a round-shaped structure, and its upper and lower sides are both open structures. Two parallel paper reels 2 are installed in the frame 1, and a tensioning and conveying roller device 3 is also installed in the frame 1. The paper reels 2 and the tensioning and conveying roller device 3 are correspondingly arranged.

[0025] The two paper reels 2 are used to install paper rolls. The two paper reels 2 are used alternately, which solves the technical problem that the machine can only be stopped for replacement after the paper on one paper reel 2 is used up, and achieves the purpose of replacing paper rolls without stopping the machine. Specifically, when one of the paper reels 2 is used for unwinding paper, the operator replaces the paper roll on the other paper reel 2, and the operator stands on the two side plates 46.2 of the paper reel 2 to be replaced to operate.

[0026] The end of each paper reel 2 is connected to an unwinding motor, which is installed on the outside of the frame 1. When in use, the unwinding motor is started, and the unwinding motor drives the paper reel 2 to rotate and continuously unwind the paper.

A folding plate is provided on one side of the mounting plate. The angle between the mounting plate and the folding plate is 135 degrees to 185 degrees. In this embodiment, the angle is 170 degrees. A blade is connected to the folding plate through a pressing plate. The blade is arranged between the folding plate and the pressing plate. The folding plate and the pressing plate are connected and fixed by screws. The cutting edge of the blade is serrated. Since the overall volume of the cutting knife 34 is relatively large, when replacing, the blade at the front end can be removed and the blade can be replaced. There is no need to remove the entire cutting knife 34 for replacement, which is convenient for operation. The serrated cutting edge increases the sharpness of the blade, which is convenient for cutting paper.

[0031] When the paper on one of the paper reels 2 is about to be delivered, the operator first evenly applies glue on one end of the paper on the other paper reel 2, and then passes the adjacent first steering support roller 35 and stretches it downward until it is between the two clamping plates 31. The two clamping plates 31 clamp the two papers together and drive the corresponding cutting knife 34 to cut off the unnecessary paper at the end of the paper roll with the blade, thus realizing continuous paper feeding without stopping the machine. The operator installs a new paper roll on the delivered paper reel 2 to prepare for subsequent paper feeding.
