Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically a paper cutting roller device for a double roll paper cutting and laying machine. Background Technology

[0002] Photovoltaic glass is a special type of glass used in the manufacture of solar panels, characterized by high light transmittance, low reflectivity, and high mechanical strength. During the production process, photovoltaic glass requires surface treatment to prevent contamination or damage. A common surface treatment method involves laying a layer of paper on the photovoltaic glass surface to isolate it from moisture and impurities in the air, keeping the surface clean and dry.

[0003] A paper-laying machine is a device used to lay paper onto the surface of photovoltaic glass, primarily for protection and isolation during the photovoltaic glass production process. The main function of the paper-laying machine is to feed the paper onto the photovoltaic glass and cut and position it according to the size and shape of the photovoltaic glass to achieve adhesion between the paper and the glass. The performance and precision of the paper-laying machine directly affect the quality and production efficiency of the photovoltaic glass.

[0004] Existing paper-laying machines, such as the "Online Electrostatic Continuous Paper Laying Machine and Paper Laying Method for Photovoltaic Glass" disclosed in patent publication number CN116788911A, and the "Paper Cutting Device for Paper Laying Machine" disclosed in patent publication number CN220222945U, use correspondingly arranged cutter mechanisms and paper suction mechanisms for paper cutting. The cutter mechanism is positioned above the paper suction mechanism to cut the paper fed by the paper conveying roller. The paper cutting is achieved through the cooperation of the cutter mechanism and the paper suction mechanism. This structure also includes a gravity roller, positioned above the paper suction mechanism. The gravity roller's paper-pressing mechanism applies pressure to the paper in a way that prevents the paper from slipping or shifting during the cutting process, thereby improving cutting accuracy and stability. However, this structure has the following drawbacks: During paper cutting, the paper suction mechanism and gravity roller work together to ensure the paper remains stable. However, this structure requires a pause after each cut, and the paper must be manually passed back through the suction mechanism and gravity roller. Otherwise, due to the inertia of the rotating gravity roller, the paper is prone to curling up, which is detrimental to subsequent cutting. This results in the machine needing to stop after each cut, significantly impacting work efficiency. To solve this technical problem, the applicant has designed a double-roller paper laying machine, and this application pertains to the paper cutting roller structure for this paper laying machine.

The paper cutting roller also has an installation groove along its generatrix. The cross-section of the installation groove is triangular. The installation groove is divided into multiple independent opening grooves by the second annular groove. A paper cutting blade is installed in each installation groove. After installation, the cutting edge of the paper cutting blade protrudes outward. Because the cutting edge of the paper cutting blade protrudes from the circumference of the paper cutting roller.

[0011] The pressure roller assembly includes a fixed frame, on which the pressure roller is connected via a connecting device, and at least one clamping device is installed on the fixed frame, which clamps the pressure roller accordingly.

[0012] The connecting device includes a first connecting seat, which connects to a first swing plate. One side of the first swing plate is connected to the fixed frame via a first spring, and the other side of the first swing plate is sleeved onto the pressure roller via a sleeve.

[0013] At least one positioning wheel assembly is also installed on the fixed frame, and the positioning wheel assembly is arranged on both sides of the pressure roller corresponding to the pressing device;

[0014] The pressing device includes a second connecting seat, which connects to a second swing plate. One side of the second swing plate is connected to a fixed plate via a second spring.

The two sets of corresponding support rollers and pressure rollers before and after the paper cutting roller are used to press the paper during cutting and to convey the paper after cutting.

[0018] 2. This device changes the paper cutting process from flat cutting to rolling cutting, and the cutting blade is angled to the paper, making cutting easier and resulting in a cleaner cut. This structure also minimizes wear on the cutting blade. Using multiple cutting blades, when the blades become dull, only the dull blades need to be replaced, resulting in low usage and maintenance costs.

[0032] The pressure roller assembly 11 includes a fixing frame 14, which includes a Z-shaped plate. End plates are provided at both ends of the fixing frame 14, and the end plates are connected to the side plate 10.1 by screws. Reinforcing ribs are provided between the vertical plate, the upper plate, and the lower plate of the Z-shaped plate.

[0033] The pressure roller 16 is connected to the fixed frame 14 via two connecting devices 15, which are respectively connected to both ends of the pressure roller 16. Each connecting device 15 includes a first connecting seat 15.1, which connects to a first swing plate 15.2. The first connecting seat 15.1 is a conventional U-shaped plate and is connected to the fixed frame 14 by screws. The first swing plate 15.2 is a square plate and is connected to the U-shaped groove of the first connecting seat 15.1 via a pin 15.5, allowing the first swing plate 15.2 to swing around the pin 15.5. One end of the first swing plate 15.2 has an open slot, and the other end has a sleeve 15.4. A fixing pin is inserted into the open slot, connecting one end of a first spring 15.3. The other end of the first spring 15.3 is connected to the fixed frame 14 by screws. The sleeve 15.4 is fitted onto one end of the pressure roller 16, and a bearing is installed inside the sleeve 15.4, allowing the pressure roller 16 and the sleeve 15.4 to rotate relative to each other.

[0034] Two clamping devices 17 and two positioning wheel assemblies 18 are also installed on the fixed frame 14, with the clamping devices 17 and positioning wheel assemblies 18 located on both sides of the pressure roller 16. The connecting device 15, the clamping devices 17, and the positioning wheel assemblies 18 work together to fix the pressure roller 16.

[0035] The pressing device 17 includes a second connecting seat 17.1, which is also a conventional U-shaped plate. The second connecting seat 17.1 is connected to the horizontal plate of the fixing frame 14 near the pressure roller 16 by screws. A second swing plate 17.2 is connected to the U-shaped groove of the second connecting seat 17.1 by a hinge shaft, and the second swing plate 17.2 can swing around the hinge shaft. There is an opening slot at both ends of the second swing plate 17.2. A pressure roller 17.5 is installed in one opening slot, and the pressure roller 17.5 presses the pressure roller 16.

A support wheel 18.2 is mounted on the second support frame 18.1, and the support wheel 18.2 serves to limit the movement of the pressure roller 16.

[0037] An L-plate 53 is connected to each side of the third support frame 10.2. Each L-plate 53 is connected to a fixing seat 54, and an air blowing pipe 55 is connected between the two fixing seats 54. The air blowing pipe 55 is positioned between the two pressure roller assemblies 11. The fixing seat 54 consists of two clamping plates, with a slot for connecting the air blowing pipe 55 between the two clamping plates. During installation, both ends of the air blowing pipe 55 are inserted into the slots of the fixing seats 54 on both sides, and the two clamping plates are locked with screws to fix the air blowing pipe 55. A row of air blowing holes is provided along the generatrix on the lower side of the air blowing pipe 55, facing the support assembly 7. One end of the air blowing pipe 55 is connected to a blower through an air pipe. During operation, the blower blows air into the air blowing pipe 55, and the air blown out from the air blowing holes applies downward pressure to the paper between the paper pressing assembly 6 and the support assembly 7, keeping the paper between the two pressure roller assemblies 11 taut for easy cutting. At the same time, after cutting, when the paper is conveyed forward, it is kept in contact with the pad 21 to prevent the paper from curling up and causing problems such as not being able to pass through the paper pressing assembly 6 and the support assembly 7.

[0038] Combination Figure 5 and Figure 6As shown, the support assembly 7 includes a first support frame 12, on which two support rollers 13 are mounted, and the paper cutting roller 8 is disposed between the two support rollers 13. Each support roller 13 is correspondingly matched with a pressure roller 16. Two drive motors 20 are also mounted on the first support frame 12, each drive motor 20 driving and connecting to a support roller 13. During paper conveying, the paper pressing assembly 6 is pulled back by the drive component 25, causing the pressure roller 16 to press against the support roller 13 to achieve paper conveying.

[0039] The first support frame 12 includes two parallel upright plates 12.1. The upright plates 12.1 are trapezoidal plates with an inclined upper side, so that after the paper pressing assembly 6 and the support assembly 7 are engaged, the contact surface between them is inclined downward, allowing the paper to be conveyed obliquely downward by the paper cutting device 5 onto the photovoltaic glass conveying roller device 4. A set of support rods 12.2 are connected between the two upright plates 12.1. The support roller 13 and the paper cutting roller 8 are rotatably connected between the two upright plates 12.1. The paper cutting motor 19 is installed on the outside of the upright plate 12.1, and the two drive motors 20 are installed on the outside of the other upright plate 12.1.

[0040] The support roller 13 is a circular rubber roller. A set of parallel first annular grooves 13.1 are provided on the support roller 13. Support rollers 13 between any two adjacent first annular grooves 13.1 are correspondingly positioned within corresponding clearance holes 21.1. A partition is provided between two adjacent clearance holes 21.1, and the partition is also correspondingly positioned within its respective first annular groove 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 drive 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 has the same number of annular grooves as the first annular grooves 13.1 and their corresponding positions.

[0041] The paper-cutting roller 8 is also a circular roller. A second connecting shaft 8.3 connecting 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 support rollers 13. A set of parallel second annular grooves 8.1 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 positioned within the corresponding clearance holes 21.1. A partition between two adjacent clearance holes 21.1 is correspondingly positioned within the second annular grooves 8.1. An mounting groove 8.2 is also provided along its generatrix on the paper cutting roller 8. The mounting groove 8.2 has a triangular cross-section and is divided into multiple independent structures by a second annular groove 8.1. One 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. Because the cutting edge of the paper cutting blade 9 protrudes from the circumference of the paper cutting roller 8, when cutting paper, the paper cutting roller 8 rotates and the paper cutting blade 9 contacts the paper at a certain angle, making it easier than vertical cutting in the prior art, and the cut of the paper is relatively flat. At the same time, this structure causes less wear on the cutting edge of the paper cutting blade 9. When multiple paper cutting blades 9 are used, when the blade edge becomes dull, only the dull paper cutting blade 9 needs to be replaced, resulting in low use and maintenance costs.
