Description

Technical Field

[0001] The utility model relates to the technical field of paper production guiding and tensioning devices, and particularly relates to a surface paper guiding and tensioning device for corrugated board production. Background Technique

[0002] Corrugated board is a multi-layer packaging material composed of at least one layer of wavy corrugated paper and one layer of surface paper bonded together. During the production process of corrugated board, the surface paper guiding and tensioning device is used to ensure that the surface paper maintains appropriate tension and correct position before entering the corrugating machine, thereby reducing paper breakage and wrinkles during the production process and ensuring the flatness and strength of the surface paper.

[0003] When guiding and tensioning the surface paper, the tightness of the surface paper is usually adjusted by directly adjusting the height of the tensioning roller. The adjustment range depends on the movable height of the tensioning roller, which is relatively rough and has a small adjustment range, resulting in the tightness of the surface paper being prone to being too loose or too tight, affecting subsequent processing. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a surface paper guiding and tensioning device for corrugated board production, which can effectively solve the technical problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The tensioning mechanism includes a rotating ring, a worm gear and a tensioning roller. The rotating ring and the worm gear are respectively rotatably installed at both ends of the surface of the installation roller. Connecting frames are rotatably installed at both ends of the tensioning roller, and telescopic components are arranged between the connecting frames and the rotating ring and the worm gear respectively. The worm gear is meshed with a worm.

[0008] As a further scheme of the utility model, there are two tensioning mechanisms, which are staggered on the installation roller, and a guiding roller is fixedly installed inside the frame.

[0009] As a further scheme of the utility model, fixed frames are rotatably installed at both ends of the worm. A first bevel gear is fixedly connected to one end of the worm, the first bevel gear is meshed with a second bevel gear, and a handle is fixedly connected to the second bevel gear.

[0010] As a further solution of the present utility model, the telescopic assembly includes a sliding rod, which is fixedly connected to the connecting frame. A bottom rod is slidably mounted on the surface of the sliding rod. A rotating seat is fixedly installed at the bottom end inside the sliding rod. Two adjusting rods are rotatably mounted on the surface of the rotating seat. The two adjusting rods are elastically connected by a spring. A plurality of card slots are formed on both sides inside the bottom rod.

[0011] As a further solution of the present utility model, the card slots are arranged in an array, and the bottom end of the adjusting rod is adapted to the card slots.

[0012] As a further solution of the present utility model, one side of the top end of the adjusting rod penetrates through the surface of the sliding rod and is slidably connected to the sliding rod.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By providing a tensioning mechanism, the tensioning roller can be height-adjusted under the action of the telescopic assembly and can also rotate within a certain range along the mounting roller, and the two do not interfere with each other, thereby effectively expanding the adjustment range of the tightness of the facial tissue.

Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1-6 shown, a surface paper guiding and tensioning device for corrugated cardboard production includes a frame 1, a feeding roller 2 and a discharging roller 4. Both the feeding roller 2 and the discharging roller 4 are connected to a power source, so that the surface paper can be guided and conveyed through the feeding roller 2 and the discharging roller 4. The mounting roller 5 is fixedly installed in the frame 1, and a tensioning mechanism 6 is arranged on the mounting roller 5, which can rotate and adjust the height of the tensioning roller 11, so that the tightness of the surface paper can be adjusted from two aspects, expanding the range of tightness adjustment. And when changing the paper, there is no need to stop the machine.

[0025] The tensioning mechanism 6 includes a rotating ring 7, a worm gear 8 and a tensioning roller 11. The rotating ring 7 and the worm gear 8 are respectively rotatably installed at both ends of the surface of the mounting roller 5. Both ends of the tensioning roller 11 are rotatably installed with connecting frames 10. Telescopic assemblies 9 are arranged between the two connecting frames 10 and the rotating ring 7 and the worm gear 8 respectively. The telescopic assemblies 9 can adjust the height of the connecting frames 10, thereby adjusting the tightness of the surface paper. The worm gear 8 is meshed with a worm 12. The worm 12 has a self-locking function. Rotating the worm 12 can drive the worm gear 8 to rotate, so as to adjust the tensioning roller 11 within a certain angle range. Through the self-locking of the worm 12, the angle adjustment is more convenient.

[0026] In this embodiment, there are two tensioning mechanisms 6, which are arranged alternately on the mounting roller 5. A guiding roller 3 is fixedly installed in the frame 1. There are two feeding rollers 2 and two guiding rollers 3, and they are symmetrically arranged. When changing the paper, the surface paper passes through the other feeding roller 2, the tensioning mechanism 6 and the guiding roller 3 respectively. By adjusting the tensioning mechanism 6, the tightness of the surface paper can be adjusted, and thus the surface paper can be replaced without stopping the machine.

[0027] In this embodiment, fixed brackets 13 are rotatably installed at both ends of the worm 12. The fixed brackets 13 can be fixedly installed on the mounting roller 5 or the frame 1, so as to prevent the telescopic assembly 9 from being blocked by the fixed brackets 13 when rotating. One end of the worm 12 is fixedly connected to a first bevel gear 14. The first bevel gear 14 is meshed with a second bevel gear 15. The second bevel gear 15 is fixedly connected to a handle 16. By rotating the handle 16, the worm wheel 8 can be driven to rotate through the meshing between the gears, so as to facilitate the adjustment of the position of the tension roller 11, and thus adjust the tightness when the facial tissue is guided and conveyed.

[0028] In this embodiment, the telescopic assembly 9 includes a sliding rod 902. The sliding rod 902 is fixedly connected to the connecting frame 10. A bottom rod 901 is slidably installed on the surface of the sliding rod 902. The sliding rod 902 can freely slide along the inside of the bottom rod 901, so as to adjust the relative height between the sliding rod 902 and the bottom rod 901. A rotating seat 903 is fixedly installed at the bottom end inside the sliding rod 902. Two adjusting rods 904 are rotatably installed on the surface of the rotating seat 903. The two adjusting rods 904 are elastically connected by a spring 905. The spring 905 fixes the positions of the two adjusting rods 904, playing a role in support and reset. A plurality of card slots 906 are formed on both sides inside the bottom rod 901.

[0029] In this embodiment, the card slots 906 are arranged in an array. The bottom end of the adjusting rod 904 is adapted to the card slots 906. The engagement between the adjusting rod 904 and the card slots 906 plays a limiting role, so that the position of the sliding rod 902 is fixed.

[0030] In this embodiment, one side of the top end of the adjusting rod 904 penetrates through the surface of the sliding rod 902 and is slidably connected to the sliding rod 902. By pressing the adjusting rod 904 outside the sliding rod 902, the adjusting rod 904 can be rotated along the rotating seat 903, so that the adjusting rod 904 is disengaged from the card slot 906, and thus the limit can be released for height adjustment.

[0031] It should be noted that the present utility model is a facial tissue guiding and tensioning device for corrugated cardboard production. When in use, refer to Figure 2 , the facial tissue is sequentially guided and output through the feeding roller 2, the tension roller 11, the guiding roller 3 and the discharging roller 4. By rotating the handle 16, the handle 16 drives the second bevel gear 15 to rotate. Through the meshing between the gears, the first bevel gear 14 is driven to rotate, thereby driving the worm 12 to rotate, and further driving the worm wheel 8 to rotate to adjust the angle of the tension roller 11, so as to adjust the tightness of the facial tissue.

[0032] By pressing the top end of the adjusting rod 904, the adjusting rod 904 can rotate along the rotating base 903, so that the bottom end of the adjusting rod 904 disengages from the card slot 906, releasing the limit, and then the sliding rod 902 can be adjusted along the bottom rod 901. After the adjustment is completed, the adjusting rod 904 is released, and under the action of the elastic force of the spring 905, the adjusting rod 904 is re-engaged with the card slot 906 to play a limiting role, so that the relative height of the sliding rod 902 and the bottom rod 901 can be adjusted, thereby expanding the range of tension adjustment.

[0033] When paper replacement is required, refer to Figure 3 , the new facial tissue passes through the feeding roller 2, the tension roller 11, and the guiding roller 3 at the lower end. The position of the tension roller 11 is adjusted through the tensioning mechanism 6, so that the tension of the facial tissue is appropriate, and then the facial tissue can be passed through the discharging roller 4 to complete paper replacement without stopping the machine.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
