Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and specifically relates to a double-roll rotary cutting paper laying machine. Background Art

[0002] Photovoltaic glass is a special photovoltaic glass used for making solar panels, which has characteristics such as high light transmittance, low reflectivity, and high mechanical strength. During the production process of photovoltaic glass, surface treatment is required 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] A paper laying machine is a device used to lay paper on the surface of photovoltaic glass, mainly for protection and isolation during the production process of photovoltaic glass. The main function of the paper laying machine is to convey the paper onto the photovoltaic glass and cut and position it according to the size and shape of the photovoltaic glass to achieve the fitting of 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] Existing paper laying machines such as the "Online Electrostatic Continuous Paper Laying Machine for Photovoltaic Glass and Paper Laying Method" disclosed in Patent Publication No. CN116788911A and the "Paper Cutting Device of Paper Laying Machine" disclosed in Patent Publication No. CN220222945U. Their paper cutting mechanism is through a corresponding cutter head mechanism and paper suction mechanism. The cutter head mechanism is arranged above the paper suction mechanism to cut the paper fed by the paper conveying roller. The cutting of the paper is achieved through the cooperation of the cutter head mechanism and the paper suction mechanism. This structure also sets gravity rollers, which are arranged above the paper suction mechanism. The gravity roller pressing mechanism applies pressure to the paper through the following method to facilitate the situation of the paper slipping or shifting during the cutting process, thereby improving the cutting accuracy and stability. However, this structure has the following disadvantages: Since when cutting the paper, the paper suction mechanism and the gravity rollers need to work together to ensure the stability of the paper. But this structure needs to pause every time the paper is cut, and the paper needs to be manually passed through the paper suction mechanism and the gravity rollers again. Otherwise, due to the inertial effect of the rotation of the gravity rollers, it is easy for the paper to show the phenomenon of warping, which is not conducive to subsequent cutting. This results in the machine needing to stop every time it cuts the paper, which greatly affects the work efficiency. Summary of the Invention

A folding plate is provided on one side of the mounting plate. The included angle between the mounting plate and the folding plate is 135 degrees - 185 degrees. In this solution, it 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 is removed and the blade is replaced, without removing the entire cutting knife 34 for replacement, which is convenient for operation. The serrated cutting edge increases the sharpness of the blade and is convenient for cutting paper.

[0032] When the paper on one of the paper reels 2 is about to be used up, the operator first evenly applies glue to one end of the paper on the other paper reel 2, then bypasses the adjacent first turning support roller 35 and stretches it downward until it reaches between the two clamping plates 31. The two papers are bonded together by clamping with the two clamping plates 31. At the same time, the corresponding cutting knife 34 is driven, and the unnecessary paper at the tail of the paper roll is cut off by the blade, realizing continuous paper feeding operation without stopping the machine.

[0045] The positioning wheel assembly 18 includes a second support frame 18.1. The second support frame 18.1 is also a U-shaped plate. The second support frame 18.1 and the second joint seat 17.1 are installed on the same cross plate of the fixed frame 14, and the second support frame 18.1 and the second joint seat 17.1 are installed on both sides of the cross plate of the fixed frame 14. A support wheel 18.2 is installed on the second support frame 18.1, and the support wheel 18.2 plays a role in limiting the pressure roller 16.

[0046] On both sides of the third support frame 10.2, an L-shaped plate 53 is respectively connected. Each L-shaped plate 53 is connected to a fixed seat 54. A blowing pipe 55 is connected between the two fixed seats 54. The blowing pipe 55 is arranged between the two pressure roller assemblies 11. The fixed seat 54 is composed of two clamping plates. A clamping groove for connecting the blowing pipe 55 is arranged between the two clamping plates. During installation, both ends of the blowing pipe 55 are respectively inserted into the clamping grooves of the fixed seats 54 on both sides, and the two clamping plates are locked by screws to fix the blowing pipe 55. A row of blowing holes is arranged along the generatrix on the lower side of the blowing pipe 55, and the blowing holes face the support assembly 7. One end of the blowing pipe 55 is connected to a blower through a trachea. During operation, the blower works to send air to the blowing pipe 55, and the air blows out from the blowing holes, pressing down on the paper between the paper pressing assembly 6 and the support assembly 7, making the paper between the two pressure roller assemblies 11 taut, which is convenient for cutting. At the same time, after cutting, when the paper is conveyed forward later, the paper is always attached to the backing plate 21, preventing the paper from warping and causing problems that it cannot be conveyed out between the paper pressing assembly 6 and the support assembly 7.

[0047] Combined with Figure 9 and Figure 10 As shown, the support assembly 7 includes a first support frame 12. Two support rollers 13 are installed on the first support frame 12. The paper cutting roller 8 is arranged between the two support rollers 13. Each support roller 13 corresponds to and cooperates with the corresponding pressure roller 16. Two drive motors 20 are also installed on the first support frame 12, and each drive motor 20 is correspondingly drivingly connected to the support roller 13. When conveying the paper, the paper pressing assembly 6 is pulled back by the driving member 25, so that the pressure roller 16 presses against the support roller 13 to realize the conveyance of the paper.

[0048] The first support frame 12 includes two parallel vertical plates 12.1. The vertical plates 12.1 are trapezoidal plates, and the upper sides of the vertical plates 12.1 are beveled edges. After the paper pressing assembly 6 and the support assembly 7 are cooperated, the contact surface between the two is inclined downward, so that the paper is obliquely downward conveyed to the photovoltaic glass conveying roller device 4 by the paper cutting device 5. A group of support rods 12.2 are connected between the two vertical plates 12.1. The support roller 13 and the paper cutting roller 8 are both rotatably connected between the two vertical plates 12.1. The paper cutting motor 19 is installed outside the vertical plate 12.1, and the two drive motors 20 are installed outside the other vertical plate 12.1.

[0049] The support roller 13 is a circular rubber roller, and a group of parallel first annular grooves 13.1 are provided on the support roller 13. The support roller 13 between any two adjacent first annular grooves 13.1 is correspondingly arranged in the corresponding clearance holes 21.1. A partition is provided between the two adjacent clearance holes 21.1, and the partition is correspondingly arranged in the corresponding first annular grooves 13.1. After installation, the highest point of the support roller 13 is higher than the upper side of the pad 21. A first connecting shaft 13.2 is provided at one end of the support roller 13, and the first connecting shaft 13.2 is connected to the transmission motor 20. The pressure roller 16 has the same structure as the support roller 13 and is also a circular rubber roller. The pressure roller 16 is provided with annular grooves of the same number and corresponding positions as the first annular grooves 13.1.

[0050] The paper cutting roller 8 is also a round roller, and a second connecting shaft 8.3 connected to the paper cutting motor 19 is provided at one end of the paper cutting roller 8. The paper cutting motor 19 drives the paper cutting roller 8 to rotate in the same direction as the two supporting rollers 13. A group of second annular grooves 8.1 arranged in parallel are provided on the paper cutting roller 8. The paper cutting roller 8 between any two adjacent second annular grooves 8.1 is also correspondingly arranged in the corresponding clearance holes 21.1, and the partition between the two adjacent clearance holes 21.1 is correspondingly arranged in the second annular groove 8.1. A mounting groove 8.2 is also provided on the paper cutting roller 8 along its generatrix. The cross section of the mounting groove 8.2 is a triangular structure. The mounting groove 8.2 is divided into a plurality of independent structures by the second annular groove 8.1. A paper cutting blade 9 is installed in each mounting groove 8.2. After installation, the cutting edge of the paper cutting blade 9 protrudes outward. Since the cutting edge of the paper cutting blade 9 protrudes from the circumferential surface of the paper cutting roller 8, when the paper is cut, the paper cutting blade 9 is rotated by the paper cutting roller 8 and contacts the paper, and is tilted at a certain angle. Compared with the vertical cutting in the prior art, the cutting is easy, and the cut of the paper after cutting is relatively smooth. At the same time, this structure causes less wear on the cutting edge of the paper cutting blade 9. When a plurality of paper cutting blades 9 are used, when the cutting edge of the blade is blunt, only the blunt-edged paper cutting blade 9 needs to be replaced, and the use and maintenance costs are low.
