Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically a paper conveying device for a double-roll roll cutting and laying paper 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 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 feeder, and this application pertains to the paper conveying device for this paper feeder. Utility Model Content

[0036] like Figure 1As shown, this utility model relates to a paper conveying device for a double-roll roll cutting and laying paper machine, including a frame 1. The frame 1 is a rectangular frame with a U-shaped structure, and its upper and lower sides are open. Two parallel paper rolls 2 are installed inside the frame 1. A tension conveyor roller device 3 is also installed inside the frame 1, with the paper rolls 2 and the tension conveyor roller device 3 correspondingly arranged. A paper cutting device 5 is installed on the lower front side of the frame 1. The paper cutting device 5 is equipped with a transmission roller device, which includes a pressure roller assembly 6 and a support roller assembly 7 that cooperate with each other. Paper rolls are installed on the paper rolls 2. The rotation of the paper rolls 2 continuously releases the paper, which is then guided into the paper cutting device 5 through the tension conveyor roller device 3.

[0037] Both paper rolls 2 are used to load paper rolls. The two paper rolls 2 are used alternately, which solves the technical problem that when the paper on one paper roll 2 runs out, the machine must be stopped for replacement. This achieves the goal of replacing paper rolls without stopping the machine. Specifically, when one paper roll 2 is used for unwinding paper, the operator replaces the paper roll on the other paper roll 2. The operator stands on the platforms 46.2 on both sides of the paper roll 2 to be replaced to perform the operation.

[0038] Each paper roll 2 is connected to an unwinding motor at its end. The unwinding motor is installed on the outside of the frame 1. When in use, the unwinding motor is started, and the unwinding motor drives the paper roll 2 to rotate and continuously release the paper.

[0039] Combination Figure 2 and Figure 3 As shown, a paper splicing device 26 is also installed inside the frame 1, and the paper splicing device 26 is located between the two paper rolls 2. The paper splicing device 26 can splice the paper on the two paper rolls 2 together, that is, when the paper roll on one paper roll 2 is about to be finished, the paper on the other paper roll 2 is connected together by the paper splicing device 26, thus achieving the purpose of changing the paper roll without stopping the machine.

[0040] The paper splicing device 26 includes a partition 27, which is vertically connected to the frame 1 by screws. A first steering support roller 35 is provided on each of the two sides above the partition 27. Each first steering support roller 35 is connected to the frame 1 via bearings. The two first steering support rollers 35 are arranged in the same horizontal plane, as are the two paper rolls 2, which are also arranged in the same horizontal plane. The two first steering support rollers 35 are positioned between the two paper rolls 2, and the horizontal plane of the first steering support rollers 35 is higher than the horizontal plane of the paper rolls 2. The first steering support rollers 35 can change the conveying direction of the paper released from the paper rolls 2, allowing the paper to be conveyed downwards.

[0041] A paper-cutting device 28 is provided below the partition 27. The paper-cutting device 28 includes two supports 29 positioned below the partition 27. The supports 29 are square plate structures, positioned on the same horizontal plane, and respectively on both sides of the partition 27. A clamping plate 31 is connected to each support 29 via two first slide rails 48. Each clamping plate 31 is vertically positioned, and the two clamping plates 31 are parallel to each other and parallel to the partition 27. Each first slide rail 48 is connected to the clamping plate 31 by an L-shaped plate 49. A clamping drive component 30, which is a hydraulic cylinder, is also installed on each support 29. Each clamping drive component 30 drives the corresponding clamping plate 31, and is connected to the vertical central axis of the clamping plate 31. The two first slide rails 48 are symmetrically arranged with the clamping drive component 30 as the center. This structure ensures the stability of the clamping plate 31 during movement. When connecting papers from two paper rolls 2, two clamping drives 30 drive two clamping plates 31 to clamp the papers, preparing them for connection. A mounting bracket 32, an U-shaped plate with its opening facing downwards, is fixedly connected to each support 29. The clamping drive 30 is positioned within the U-shaped groove of the mounting bracket 32. A paper-cutting drive 33, also a hydraulic cylinder, is mounted on top of the mounting bracket 32. The paper-cutting drive 33 drives the connecting cutter 34. An I-beam 50 is screwed onto each of the supports 29 on both sides of the mounting bracket 32, with the two I-beams 50 symmetrical about the mounting bracket 32. A second slide rail 51 is mounted on each I-beam 50, and both second slide rails 51 are located at the bottom of the cutter 34, with each second slide rail 51 connected to the cutter 34. This structure increases the stability of the cutter 34's movement.

[0042] The cutting blade 34 includes a mounting plate that connects to the paper-cutting drive unit 33. The mounting plate is rectangular, and 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 to 185 degrees; in this design, it is 170 degrees. A blade is connected to the folding plate via a pressure plate, and the blade is positioned between the folding plate and the pressure plate. The folding plate and the pressure plate are connected and fixed with screws. The blade has a serrated cutting edge. Due to the relatively large overall size of the cutting blade 34, replacement is simple: only the front blade needs to be removed and replaced; the entire cutting blade 34 does not need to be removed for replacement, simplifying the operation. The serrated cutting edge increases the sharpness of the blade, facilitating paper cutting.

[0043] When one of the paper rolls 2 is about to run out of paper, the operator evenly applies adhesive to one end of the paper on the other paper roll 2, then pulls it downwards around the adjacent first steering support roller 35 until it is between the two clamping plates 31. The two clamping plates 31 clamp the two sheets of paper together, and at the same time, the corresponding cutting blade 34 is driven to cut off the unwanted paper at the end of the paper roll, achieving continuous paper feeding without stopping the machine. The operator then installs a new paper roll on the paper roll 2 after it has been fed, preparing for subsequent paper feeding.

[0044] The tension conveyor roller device 3 includes a second steering support roller 36, a support roller group 37, and a tension roller group 38. The second steering support roller 36 consists of two tension rollers, which are coplanarly arranged and both installed on the lower side inside the frame 1. One second steering support roller 36 is located below the two supports 29, and the other second steering support roller 36 is located in front of the paper splicing device 26. After passing the first steering support roller 35, the paper is conveyed by the second steering support roller 36 below the paper splicing device 26, which changes the paper's conveying direction to a horizontal direction. After passing the other second steering support roller 36, the paper is conveyed to the support roller group 37 and the tension roller group 38.

[0045] The support roller group 37 and the tension roller group 38 are arranged on the upper side inside the frame 1, and the support roller group 37 and the tension roller group 38 are arranged in a cooperative manner.

[0046] The specific connection method between the support roller group 37 and the tension roller group 38 is as follows: A rotating shaft 42 is rotatably connected to the top front side of the frame 1 via a bearing. Two tensioning drive components 39 are provided on the lower side of the rotating shaft 42, and each tensioning drive component 39 is also a hydraulic cylinder. The bottom of each tensioning drive component 39 is connected to the frame 1 via a hinge seat 52, allowing the tensioning drive component 39 to rotate around the hinge seat 52. The two tensioning drive components 39 are respectively located on both sides of the rotating shaft 42. A connecting plate 41 is welded to each side of the rotating shaft 42, and the connecting plate 41 consists of two parallel triangular plates. A ball joint connecting plate 40 is attached to one end of the piston rod of the tensioning drive component 39, allowing the connecting plate 40 to rotate 360 ​​degrees. The other end of the connecting plate 40 is connected to the connecting plate 41 via a hinge shaft. In use, the tensioning drive component 39 drives the connecting plate 40, and since the connecting plate 40 and the connecting plate 41 can rotate relative to each other, the rotating shaft 42 can rotate. A connecting seat is welded to the rotating shaft 42 on the outer side of each junction plate 41. Each connecting seat is fixedly connected to a tensioning rod 43. A tensioning roller group 38 is connected between two tensioning rods 43. The tensioning roller group 38 consists of two tensioning rollers, and both ends of each tensioning roller are connected to the corresponding tensioning rod 43 through bearing seats. The support roller group 37 is located above the tensioning rods 43. The support roller group 37 consists of three support rollers. Each fixed support roller is also connected to the frame 1 through a bearing seat, and each tensioning roller is correspondingly positioned between two fixed support rollers. The paper conveyed by the second steering support roller 36 passes around the fixed support rollers and tensioning rollers in a sequential manner, forming a wavy structure. The purpose of tensioning the paper is achieved by controlling the distance between the tensioning roller group 38 and the support roller group 37 by controlling the tensioning drive 39.

[0047] A limiting frame 44 is also provided inside the frame 1. The limiting frame 44 has a U-shaped plate structure and is connected to the inner wall of the frame 1 by screws. One tensioning rod 43 is disposed inside the limiting frame 44. An oblong through hole is provided on the bottom plate of the limiting frame 44, and a laser positioning sensor 45 is installed at each end of the oblong through hole. The laser positioning sensor 45 is existing technology. The tensioning rod 43 is positioned between the two laser positioning sensors 45, which limit the swing range of the tensioning rod 43 and play a protective role.

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.
