Description

TECHNICAL FIELD

[0001] The present application relates to the field of paper laminating machine, in particular to a pressing structure of paper laminating machine. BACKGROUND

[0002] The paper laminating machine belongs to the field of paper production machinery, in particular to a paper laminating machine for laminating two pieces of paper together, which comprises a paper feeding mechanism, a paper laminating mechanism and a paper pressing mechanism. Two air heads are arranged side by side on the paper feeding mechanism. An intermediate positioning mechanism is arranged on the paper laminating mechanism, which divides the paper laminating mechanism into two paper paths. Wing-shaped spring sheets are arranged on both sides of the paper laminating mechanism. The intermediate positioning mechanism comprises an intermediate positioning guide block and a lifting mechanism. The structure is simple and the production efficiency is improved.

[0003] After the paper laminating is completed, the paper needs to be pressed to ensure the tightness of the two pieces of paper. The existing pressing device usually uses two pressing rollers to press. The distance between the two pressing rollers is the same. When pressing paper of different thicknesses, the effect is different, which leads to poor pressing effect. When the paper of large thickness enters the pressing rollers with small distance, the two pressing rollers may separate the two pieces of paper. CONTENT OF THE INVENTION

[0004] In order to solve the problem that the effect is different when pressing paper of different thicknesses, which leads to poor pressing effect, the present application provides a pressing structure of paper laminating machine.

[0005] The pressing structure of paper laminating machine provided by the present application adopts the following technical scheme: a paper laminating machine body is provided, a paper guide block is arranged inside the paper laminating machine body, a frame is fixed to the bottom of one side of the paper laminating machine body through a connecting rod, an inclined plate is fixed to the middle of the paper laminating machine body and the frame, a supporting rod is fixed to the lower middle of one side of the frame, a servo motor is fixed to the top of the supporting rod, a rotating shaft is fixed to the power output end of the servo motor, a first pressing roller is fixed to one end of the rotating shaft and penetrates the frame, a sliding groove is formed in the upper middle of both ends of the frame, a sliding block is slidably connected inside each of the two sliding grooves, a second pressing roller is rotatably connected to the middle of the two sliding blocks, an extension rod is fixed to the top of each sliding block, a sleeve rod is movably sleeved on the top of the extension rod, a moving block is fixed to the top of the sleeve rod, and a spring is movably sleeved on the outer wall of the extension rod and the sleeve rod.

[0006] By adopting the above technical scheme, the extension rod, the sleeve rod and the spring support the sliding block, so that the second pressing roller driven by the sliding block can be kept in close contact with the first pressing roller. When the paper enters the first pressing roller and the second pressing roller, it can be fully pressed by the first pressing roller and the second pressing roller.

[0007] Preferably, the movable block is slidably connected to the top of the outer wall of the frame, the bottom end of the spring is fixed to the top of the slider, the top end of the spring is fixed to the bottom of the movable block, and the length of the spring is greater than the sum of the lengths of the telescopic rod and the sleeve rod.

[0008] By adopting the above technical solution, the spring is long enough to release sufficient elastic potential energy, so that the first and second pressure rollers fit tightly together. When paper of different thicknesses enters the first and second pressure rollers, the spring is compressed accordingly, and the telescopic rod enters the sleeve rod to keep the first and second pressure rollers able to continuously squeeze the paper.

[0009] Preferably, a fixing block is fixed at the top of both ends of the mounting machine body, a threaded rod is threaded through the middle of the fixing block, the bottom of the threaded rod is rotatably connected to the moving block, and a knob is fixed at the top of the threaded rod.

[0010] By adopting the above technical solution, the elastic potential energy of the spring weakens after long-term use, or when it is necessary to change the pressing force on the mounting paper, the screw rod is rotated on the fixed block by turning the knob, which changes the movement of the moving block downward, compresses the spring more tightly, and increases the pressing force of the first and second pressing rollers.

[0011] Preferably, the other end of the first extrusion roller is rotatably connected to the inner wall of the frame, and rubber pads are fixed to the outer walls of both the first and second extrusion rollers.

[0012] By adopting the above technical solution, the frame supports and limits the first and second extrusion rollers, and the rubber pads on the outer walls of the first and second extrusion rollers increase their friction with the paper mounting, so that the paper mounting can be moved towards the collection box while being pressed.

[0013] Preferably, both ends of the second extrusion roller are fixed with connecting shafts, and the second extrusion roller is rotatably connected to the two sliders through the two connecting shafts.

[0014] By adopting the above technical solution, the second extrusion roller can rotate inside the slider through the connecting shaft, and the second extrusion tube can move up and down while also rotating.

[0015] Preferably, the top of the inclined plate and the bottom of the paper guide block are located on the same horizontal plane, and the bottom of the inclined plate and the top of the first squeeze roller are located on the same horizontal plane.

[0016] By adopting the above technical solution, the paper inside the mounting machine enters the inclined plate from the paper guide block, and is then guided by the inclined plate to the middle of the first and second pressure rollers.

[0017] Preferably, a collection box is fixed to the bottom of the frame on the side away from the mounting machine body.

[0018] By adopting the above technical solution, the collection box is set up to collect the paper after pressing, making it more convenient to retrieve later.

[0019] In summary, this application includes at least the following beneficial technical effects:

[0020] 1. This application supports the slider with a telescopic rod, a sleeve rod, and a spring, so that the slider can drive the second extrusion roller to keep it in close contact with the first extrusion roller. When the paper enters the first and second extrusion rollers, it can be fully pressed by the first and second extrusion rollers. When paper of different thicknesses enters the first and second extrusion rollers, the spring is compressed accordingly, and the telescopic rod enters the sleeve rod to keep the first and second extrusion rollers pressing the paper continuously. This achieves the effect that the distance between the two extrusion rollers can be adjusted and is suitable for pressing paper of various thicknesses.

[0021] 2. When the elastic potential energy of the spring weakens after prolonged use, or when it is necessary to change the pressing force on the mounting paper, the screw rod is rotated on the fixed block by turning the knob, which causes the moving block to move downward, the spring is compressed more tightly, and the pressing force of the first and second pressing rollers is increased, thereby achieving the effect of quickly adjusting the pressing force.

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses a pressing structure for a paper mounting machine, including a paper mounting machine body 1. A paper guide block 2 is disposed inside the paper mounting machine body 1. A frame 4 is fixed to the bottom of one side of the paper mounting machine body 1 via a connecting rod. An inclined plate 3 is fixed in the middle of the paper mounting machine body 1 and the frame 4. A support rod 6 is fixed to the lower middle of one side of the frame 4. A servo motor 7 is fixed to the top of the support rod 6. A rotating shaft 8 is fixed to the power output end of the servo motor 7. One end of the rotating shaft 8 passes through the frame 4 and is fixed with a first pressing roller 9. Slide grooves 11 are provided above the middle of both ends of the frame 4. Sliding sliders 12 are slidably connected inside each of the two slide grooves 11, and a second pressing roller 10 is rotatably connected to the middle of each of the two sliding sliders 12. The first pressing roller 9 and the second pressing roller 10 are tightly fitted together. Paper of different thicknesses enters the first pressing roller... When the first and second extrusion rollers 9 and 10 are in the pressure rollers 9 and 10 respectively, the spring 16 is compressed accordingly. The telescopic rod 14 enters the sleeve 15. The top of the slider 12 is fixed with the telescopic rod 14, and the top of the telescopic rod 14 is movably sleeved with the sleeve 15. The telescopic rod 14 enters the sleeve 15, keeping the first and second extrusion rollers 9 and 10 able to continuously extrude paper. The top of the sleeve 15 is fixed with a moving block 17. The telescopic rod 14 and the outer wall of the sleeve 15 are movably sleeved with the spring 16. The slider 12 is supported by the telescopic rod 14, the sleeve 15 and the spring 16, so that the slider 12 can drive the second extrusion roller 10 to keep it in close contact with the first extrusion roller 9. When the paper enters the first and second extrusion rollers 9 and 10, it can be fully pressed by the first and second extrusion rollers 9 and 10.

[0029] The movable block 17 is slidably connected to the top of the outer wall of the frame 4. The bottom end of the spring 16 is fixed to the top of the slider 12, and the top end of the spring 16 is fixed to the bottom of the movable block 17. The length of the spring 16 is greater than the sum of the lengths of the telescopic rod 14 and the sleeve rod 15. The length of the spring 16 is sufficient to release sufficient elastic potential energy, so that the first pressing roller 9 and the second pressing roller 10 are tightly fitted together. When mounting paper of different thicknesses enters the first pressing roller 9 and the second pressing roller 10, the spring 16 is compressed accordingly, and the telescopic rod 14 enters the sleeve rod 15, so that the first pressing roller 9 and the second pressing roller 10 can continuously press the mounting paper.

[0030] The frame 4 has fixed blocks 18 at both ends of the top. A threaded rod 19 is threaded through the middle of the fixed block 18. The bottom of the threaded rod 19 is rotatably connected to the moving block 17. A knob 20 is fixed at the top of the threaded rod 19. After long-term use, the elastic potential energy of the spring 16 weakens. When it is necessary to change the pressure on the paper mounting, the threaded rod 19 is rotated on the fixed block 18 by rotating the knob 20. This changes the movement of the moving block 17 downward, compresses the spring 16 more tightly, and increases the pressure of the first pressure roller 9 and the second pressure roller 10.

[0031] The other end of the first extrusion roller 9 is rotatably connected to the inner wall of the frame 4. Rubber pads are fixed on the outer walls of both the first extrusion roller 9 and the second extrusion roller 10. The frame 4 supports and limits the first extrusion roller 9 and the second extrusion roller 10. The rubber pads on the outer walls of the first extrusion roller 9 and the second extrusion roller 10 increase their friction with the paper, so that the paper can be moved toward the collection box 5 while being pressed.

[0032] The second extrusion roller 10 is fixed with connecting shafts 13 at both ends. The second extrusion roller 10 is rotatably connected to the two sliders 12 through the two connecting shafts 13, so that the second extrusion roller 10 can rotate inside the slider 12 through the connecting shafts 13. The second extrusion tube 10 can move up and down and rotate at the same time.

[0033] The top of the inclined plate 3 and the bottom of the paper guide block 2 are on the same horizontal plane, and the bottom of the inclined plate 3 and the top of the first pressure roller 9 are on the same horizontal plane, so that the paper inside the mounting machine body 1 enters the inclined plate 3 from the paper guide block 2, and the paper is guided into the middle of the first pressure roller 9 and the second pressure roller 10 through the inclined plate 3.

[0034] Among them, a collection box 5 is fixed at the bottom of the frame 4 on the side away from the mounting machine body 1. The collection box 5 collects the mounting paper after pressing, making it more convenient to retrieve it later.

[0035] The implementation principle of the pressing structure of a paper mounting machine according to an embodiment of this application is as follows: First, the paper inside the paper mounting machine body 1 enters the inclined plate 3 through the paper guide block 2. The inclined plate 3 guides the paper into the middle of the first pressure roller 9 and the second pressure roller 10. Then, the servo motor 7 is started to drive the rotating shaft 8 and the first pressure roller 9 to rotate. The spring 16 is long enough to release sufficient elastic potential energy, so that the first pressure roller 9 and the second pressure roller 10 are tightly fitted. When paper of different thicknesses enters the first pressure roller 9 and the second pressure roller 10, the spring 16 is compressed accordingly. The telescopic rod 14 enters the sleeve rod 15 to keep the first pressure roller 9 and the second pressure roller 10 aligned with the paper. The first and second pressure rollers 9 and 10 are pressed together. The rubber pads on their outer walls increase the friction between them and the mounting paper, so that the mounting paper can be moved toward the collection box 5 while pressing. The collection box 5 collects the mounting paper after pressing, making it easier to retrieve later. After long-term use, the elastic potential energy of the spring 16 weakens, or when it is necessary to change the pressing force on the mounting paper, the screw rod 19 is rotated on the fixed block 18 by turning the knob 20. This changes the movement block 17 downward, compresses the spring 16 more tightly, and increases the pressing force of the first and second pressure rollers 9 and 10, thereby achieving the effect of quickly adjusting the pressing force.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
