Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a paper cutting and splicing device for a paper 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 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 is a paper cutting and splicing device for this paper-laying machine. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a paper cutting and splicing device for a paper laying machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A paper cutting and splicing device for a paper laying machine includes a frame, characterized in that: two paper rolls and two first steering support rollers are rotatably connected within the frame, the two first steering support rollers are disposed between the two paper rolls, a partition is installed on the lower side between the first steering support rollers, a bracket is provided below the partition, two opposing clamping drive components are installed on the bracket, each clamping drive component drives and connects to a clamping plate, the two clamping plates are arranged parallel to each other, a mounting bracket is also fixedly connected to the bracket on one side of each clamping plate, a paper cutting drive component is installed on each mounting bracket, each paper cutting drive component drives and connects to a cutting blade, the blades of the two cutting blades are arranged opposite each other.

[0008] Based on the above solutions, the following technical solutions can also be adopted:

[0009] The cutting blade includes a mounting plate that connects to the paper cutting drive component. The mounting plate is a rectangular plate with a folding plate on one side. The angle between the mounting plate and the folding plate is 10-15 degrees. A blade is connected to the folding plate by a pressure plate. The blade is positioned between the folding plate and the pressure plate, and the cutting edge of the blade is angled downwards after installation.

[0010] The angle between the mounting plate and the folding plate is degrees.

[0011] The blade has a serrated edge.

[0012] A second steering support roller is also installed on the lower side of the bracket.

[0013] The number of brackets is two, with each bracket positioned on one side below the partition. Each bracket is also connected to a first slide rail, which in turn connects to a corresponding clamping plate.

[0014] Each of the brackets is also connected to an I-beam, and a second slide rail is connected to the I-beam, with the corresponding cutting blade connected to the second slide rail.

[0015] The beneficial effects of this utility model are: This device is used in conjunction with two paper rolls, which can splice the paper on the two paper rolls together. That is, when the paper roll on one paper roll is about to be empty, the paper on the other paper roll is connected together by this device, thereby completing the paper roll switching. After the switching is completed, new paper is loaded on the empty paper roll to prepare for the next step. This effectively solves the problem that when the paper on one paper roll is used up, the machine can only be stopped for replacement, and the purpose of changing the paper roll without stopping the machine is achieved.

[0017] Figure 2 for Figure 1 A schematic diagram of the installation structure. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] like Figure 1 and Figure 2 As shown, this utility model relates to a paper cutting and splicing device for a paper laying 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 structures. Two parallel paper rolls 2 are installed inside the frame 1.

[0021] 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.

[0022] 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.

[0023] Two first steering support rollers 35 are connected by bearings within the frame 1. The two first steering support rollers 35 are positioned on the same horizontal plane as the two paper rolls 2, which are also positioned on the same horizontal plane. The two first steering support rollers 35 are located 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.

[0024] A partition 27 is installed on the lower side between the first steering support rollers 35, and the partition 27 is vertically connected to the frame 1 by screws. The two first steering support rollers 35 are respectively arranged on both sides above the partition 27.

[0025] A bracket 29 is installed on each side below the partition 27. The bracket 29 is a square plate fixedly connected to the frame 1, and the two brackets 29 are arranged on the same horizontal plane. A clamping plate 31 is connected to each bracket 29 by two first slide rails 48. Each clamping plate 31 is vertically arranged, 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 is also installed on each bracket 29. The clamping drive component 30 is a hydraulic cylinder. Each clamping drive component 30 drives the corresponding clamping plate 31. The clamping drive component 30 is connected at the vertical central axis of the clamping plate 31, and 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 when it moves. When connecting papers from two paper rolls 2, the two clamping drive components 30 drive the two clamping plates 31 to clamp the papers to prepare for connection. A mounting bracket 32 ​​is fixedly connected to each bracket 29. The mounting bracket 32 ​​is a U-shaped plate with its opening facing downwards, and the clamping drive component 30 is disposed in the U-shaped groove of the mounting bracket 32. A paper-cutting drive component 33, which is also a hydraulic cylinder, is installed on the top of the mounting bracket 32. The paper-cutting drive component 33 drives the connecting cutter 34. An I-beam frame 50 is connected to each bracket 29 on both sides of the mounting bracket 32 ​​by screws. The two I-beam frames 50 are symmetrical about the mounting bracket 32. A second slide rail 51 is installed on each I-beam frame 50. The two second slide rails 51 are located at the bottom of the cutter 34, and each second slide rail 51 is connected to the cutter 34. This structure increases the stability of the movement of the cutter 34.

[0026] 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.

[0027] 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.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
