[0003] Due to the shortcomings of thermal paper such as easy damage and low bearing capacity, during the thermal paper processing and winding process, in order to compact the thermal paper and fit it on the winding roller, a force is applied to the thermal paper in the direction of the winding roller. Once the force applied to the thermal paper is controlled too small or too large, problems such as the thermal paper not being compacted after winding or the thermal paper breaking during winding will occur. In addition, it is inconvenient to cut the thermal paper according to the radius of the thermal paper wound into a column on the winding roller.

[0004] Therefore, it is urgent to improve the winding device for thermal paper production to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a winding device for thermal paper production, which can press the thermal paper on the winding roller through a pressure plate under the action of a spring, and adjust the position height of the resistance plate on the movable rod according to the winding amount of the wound thermal paper, thereby realizing cutting of thermal paper with different winding amounts.

[0006] In order to achieve the above-mentioned purpose, the main technical scheme adopted by the present invention includes: a winding device for producing thermal paper, comprising a base, a working frame is provided on the base, a winding roller for winding up the thermal paper is provided on the working frame, a driving component for driving the winding roller to rotate is provided on the working frame, a pressure plate is provided above the winding roller, a movable rod is connected to the upper end surface of the pressure plate, the other end of the movable rod passes through the working frame and is slidably connected to the working frame, a contact plate is threadedly connected to the outer wall of the circumference of the movable rod between the working frame and the pressure plate, and a pressure sensor is provided on the inner top wall of the working frame; One side of the base is provided with a controller electrically connected to the pressure sensor. An electric push rod electrically connected to the controller is provided on the inner top wall of the working frame. The movable end of the electric push rod is connected to a connecting seat. A cutter for cutting thermal paper is provided at the lower end of the connecting seat. When the pressure received by the pressure sensor exceeds a specified threshold, a signal is transmitted to the controller, and the controller starts the cutter to move downward to cut the thermal paper; A spring is provided at the upper end of the pressing plate, and the other end of the spring is connected to the inner top wall of the working frame.

[0007] Preferably, the driving assembly includes a motor connected to one side of the working frame and a driving shaft connected to the output end of the motor. An irregular insertion portion is provided at the end of the driving shaft away from the motor, and the irregular insertion portion is movably inserted into one end of the winding roller to drive the winding roller to rotate.

[0008] Preferably, a pressing groove is formed on the circumferential outer wall of the winding roller, and an elastic pressing strip is detachably connected inside the pressing groove.

[0009] Preferably, a receiving ring is screwed and connected to the side of the working frame away from the motor, and the other end of the winding roller is movably connected to one side of the receiving ring.

[0010] Preferably, a receiving cavity is formed inside the connecting seat, and a guardrail extending to the outside of the connecting seat is provided inside the receiving cavity.

[0011] Preferably, two pressing rollers are provided on the base, and the cutter is located directly above the two pressing rollers.

[0016] The present invention has at least the following beneficial effects: 1. The downward resistance force generated by the spring on the pressure plate causes the pressure plate to compact the rolled thermal paper on the winding roller, making it tighter when rolling up the thermal paper. As the thickness of the rolled thermal paper on the winding roller gradually increases, resistance will be generated on the pressure plate, causing the pressure plate to drive the movable plate and the resistance plate to move upward and press against the pressure sensor. When the controller receives a signal from the pressure sensor that exceeds the set threshold, it controls the electric push rod to drive the cutter to move downward to cut the thermal paper, making it more convenient to use.

DETAILED DESCRIPTION

[0019] The following will describe in detail the implementation manners of the present application in conjunction with the accompanying drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0020] As Figures 1-6 shown, the winding device for thermal paper production provided in this embodiment includes a base 1. A working frame 11 is provided on the base 1. A winding roller 12 for winding thermal paper is provided on the working frame 11. A driving component 2 for driving the winding roller 12 to rotate is provided on the working frame 11. The driving component 2 includes a motor 21 connected to one side of the working frame 11 and a driving shaft 22 connected to the output end of the motor 21. An irregular insertion portion 23 is provided at one end of the driving shaft 22 away from the motor 21. The cross-section of the irregular insertion portion 23 can be polygonal. The irregular insertion portion 23 is movably inserted into one end of the winding roller 12 to drive the winding roller 12 to rotate; Above the winding roller 12, there is a pressing plate 13. A movable rod 14 is connected to the upper end surface of the pressing plate 13. The other end of the movable rod 14 penetrates through the working frame 11 and is slidably connected to the working frame 11. A spring 102 is provided at the upper end of the pressing plate 13. The other end of the spring 102 is connected to the inner top wall of the working frame 11. Under the elastic force of the spring 102, the pressing plate 13 can be driven to always abut against the thermal paper wound on the winding roller 12, pressing the wound thermal paper. As the thickness of the thermal paper wound on the winding roller 12 gradually increases, the pressing plate 13 will compress the spring 102 and drive the movable rod 14 to move upward until it contacts the contact plate 15 and the pressure sensor 16. The distance between the upper end of the contact plate 15 and the lower end of the pressure sensor 16 is the radius of the columnar thermal paper bundle wound on the winding roller 12. Therefore, after determining the winding amount of the thermal paper to be wound, only need to adjust the height of the contact plate 15 on the movable rod 14, so as to adjust the distance between the contact plate 15 and the pressure sensor 16; A contact plate 15 is threadedly connected to the circumferential outer wall of the movable rod 14 between the working frame 11 and the pressing plate 13. A pressure sensor 16 is provided on the inner top wall of the working frame 11. A controller 17 electrically connected to the pressure sensor 16 is provided on one side of the base 1. An electric push rod 18 electrically connected to the controller 17 is provided on the inner top wall of the working frame 11. The movable end of the electric push rod 18 is connected with a connecting seat 19. A cutter 101 for cutting the thermal paper is provided at the lower end of the connecting seat 19. When the pressure received by the pressure sensor 16 exceeds the specified threshold, a signal is transmitted to the controller 17, and the controller 17 starts the cutter 101 to move downward to cut the thermal paper; Further, as Figure 2 shown, scale lines 8 are provided on the outer wall of the movable rod 14. By referring to the scale, the distance between the contact plate 15 and the pressure sensor 16 can be adjusted more accurately, so as to facilitate the cutting of thermal paper with different winding amounts; Furthermore, as Figure 1 shown, two pressure rollers 6 are provided on the base 1, and the cutter 101 is located directly above the two pressure rollers 6. By limiting the thermal paper with the two pressure rollers 6, the thermal paper is close to the upper end face of the base 1, minimizing the distance between the thermal paper and the base 1 as much as possible. When the cutter 101 descends to cut the thermal paper, it will not cause the thermal paper to be pressed and torn; Further, an accommodation cavity 5 is formed inside the connecting seat 19, and a guardrail 51 extending to the outside of the connecting seat 19 is provided inside the accommodation cavity 5. In the initial state, the guardrail 51 will extend to the outside of the connecting seat 19 under its own gravity. When the connecting seat 19 drives the cutter 101 to move downward, the connecting seat 19 first contacts the base 1, thereby protecting both sides of the cutter 101 to prevent a person's hand, etc. from reaching below the cutter 101. When the cutter 101 contacts the base 1, the guardrail 51 will enter the accommodation cavity 5; Further, the controller 17 is electrically connected to the driving component 2 and is used to close the driving component 2 after the controller 17 receives the electrical signal from the pressure sensor 16. When the cutter 101 moves downward to cut the thermal paper, the driving component 2 stops the winding action, thereby preventing the cutter 101 from increasing the tension of the thermal paper between the cutter 101 and the winding roller 12 when the winding roller 12 continues to rotate during the downward pressing of the thermal paper, which may cause the thermal paper to be torn; Among them, the cross-section of the pressing plate 13 is trapezoidal or "V"-shaped, etc., which can press different diameters of the winding rollers 12. When the winding amount of the thermal paper on the winding roller 12 gradually increases, the pressing plate 13 will always cover the outside of the wound thermal paper, and rounded corners 7 are provided on both sides of the pressing plate 13 to prevent the edges of the pressing plate 13 from scratching the thermal paper and causing damage to the thermal paper; Furthermore, as Figure 2 shown, a receiving ring 4 is threadedly engaged on the side of the working frame 11 away from the motor 21. The other end of the winding roller 12 is movably connected to one side of the receiving ring 4. When the receiving ring 4 is removed from the working frame 11, it is convenient to remove the winding roller 12 from the driving shaft 22. When the receiving ring 4 is installed on the working frame 11, one end of the receiving ring 4 can receive the end of the winding roller 12 away from the driving shaft 22, enabling the winding roller 12 to rotate more stably; Further, as Figure 6As shown, a pressing groove 3 is opened on the circumferential outer wall of the winding roller 12, and an elastic pressure strip 31 is detachably connected to the inside of the pressing groove 3. The elastic pressure strip 31 can be made of elastic material such as rubber, and can be deformed and clamped in the pressing groove 3 when pressed into the pressing groove 3. Before the winding work is carried out, one end of the thermal paper is pressed into the pressing groove 3, and the elastic pressure strip 31 is pressed into the pressing groove 3 to fix the thermal paper, so that one end of the thermal paper is connected to the winding roller 12, and no manual winding is required, thereby avoiding the occurrence of manual winding that is not tight.

[0021] like Figures 1-6 As shown, the method for using a winding device for producing thermal paper provided in this embodiment includes the following steps: S1: First, one end of the winding roller 12 is docked with the special-shaped inserting portion 23, and the receiving ring 4 is installed on the working frame 11 to fix the winding roller 12. Then, one end of the thermal paper is passed under the two pressing rollers 6, and one end of the thermal paper is pressed into the pressing groove 3 by the elastic pressure strip 31 to fix it on the winding roller 12; S2: Then, according to the required winding amount of the thermal paper, the position of the resistance plate 15 on the movable rod 14 is adjusted, and the motor 21 drives the winding roller 12 to rotate to wind the thermal paper. As the winding amount increases, the thermal paper on the winding roller 12 will resist the pressure plate 13, so that the movable rod 14 drives the resistance plate 15 to move upward to resist the pressure sensor 16; S3: After receiving the signal from the pressure sensor 16, the controller 17 starts the electric push rod 18 to drive the cutter 101 to move downward to cut the thermal paper.
