Description

Technical Field

[0001] The utility model relates to the field of paper tube manufacturing and processing, in particular to a limiting mechanism for paper tube cutting. Background Art

[0002] Paper tubes are tubular objects made from paper. Most paper tubes are spiral paper tubes and seamless paper tubes. Paper tubes are usually used to package rolled items such as textiles, films, plastics, etc. They are convenient for storage and transportation. At the same time, paper tubes can be used as paper core shafts to provide protection. For example, toilet paper, kitchen paper, industrial paper, etc. These roll-shaped paper products require a central support shaft to maintain their overall structure and shape.

[0003] Paper tubes are produced as a whole long tube, and then they need to be cut into multiple shorter lengths. A paper tube cutting machine is needed for cutting. The paper tube is put on the support roller of the cutting mechanism. The support roller drives the paper tube to rotate, so that the cutter cuts the whole body of the paper tube, thereby cutting the paper tube. Generally, two rotating wheels are set on the frame of the cutting machine, and the paper tube is located between the two rotating wheels to prevent the paper tube from shifting left and right when cutting. At the same time, there is rolling friction between the paper tube and the rotating wheel to prevent the rotating wheel from wearing the surface of the paper tube. The thickness of the paper tubes produced by the factory is different. In order to cut paper tubes of various diameters, rubber rings of different thicknesses are put on the support roller to increase the radius of the support roller, so that it can support paper tubes of different apertures. However, the rotating wheel cannot well limit paper tubes of the same diameter. Utility Model Content

[0004] The purpose of the utility model is to provide a limiting mechanism for paper tube cutting, which has the advantage of being able to better limit paper tubes of different diameters.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A limiting mechanism for paper tube cutting is provided with a frame. The limiting mechanism includes two connecting seats slidably connected to the upper part of one end of the frame, and a rotating wheel rotatably connected to the connecting seat. It also includes a connecting rod and a sliding rod. There are two connecting rods, and the ends of the two connecting rods are rotatably connected to the two connecting seats respectively. The sides of the end of the frame are fixedly connected with a sliding sleeve. The sliding rod vertically passes through the sliding sleeve. The sliding rod is slidably connected to the sliding sleeve of the frame. The other ends of the two connecting rods are hinged to the upper end of the sliding rod. The sliding sleeve is provided with a fixing piece for fixing the sliding rod.

[0007] By adopting the above technical solution, the paper tube is put on the supporting roller of the frame, and then one of the connecting seats is moved close to the paper tube. The movement of the connecting seat drives the sliding rod to move vertically downward through the connecting rod hinged to it. The moved sliding rod then drives the other connecting seat to move close to the paper tube through another connecting rod, so that the wheels of the two moving seats contact the outer wall of the paper tube. Then, the sliding rod is fixed by the fixing piece to fix the rotating wheel, which is convenient for adjusting the distance between the two rotating wheels so that it can limit paper tubes of different diameters, preventing the paper tube from shifting left and right when cutting the paper tube, and at the same time avoiding the rotating wheel from wearing the paper tube surface; similarly, the moving connecting seat is away from the paper tube, the sliding rod rises, driving the other connecting seat away from the paper tube, thereby separating the two rotating wheels from the paper tube.

[0008] Preferably, a gasket is provided between the two connecting seats, and the gasket is adhered to the frame.

[0009] The above technical solution is adopted to prevent the friction between the paper tube and the frame when the paper tube rotates, thereby preventing the paper tube from being worn.

[0010] Preferably, a scale is pasted on the upper side of the frame.

[0011] By adopting the above technical solution and using the ruler as a reference, the paper tube can be cut into the required length.

[0012] Preferably, the fixing member is a bolt, the bolt is horizontally threadedly connected to the side of the sliding sleeve, and the head of the bolt penetrates into the interior of the sliding sleeve and contacts the sliding rod.

[0013] By adopting the above technical solution, the bolt is screwed to tighten the slide bar, thereby fixing it.

[0014] Preferably, the sliding rod body is provided with a plurality of insertion holes, and also includes a pin, and the side of the sliding sleeve is provided with a insertion hole, the pin passes horizontally through the side of the sliding sleeve, is slidably connected to the sliding sleeve, and the pin passes through a insertion hole of the sliding rod.

[0015] By adopting the above technical solution, the distance between the two wheels is different and the height of the slide bar is different. The pin is passed through the insertion hole of the slide bar to keep the two wheels at a certain distance. Compared with fixing with bolts, the pin and the slide bar will not slip, and it is more stable.

[0016] Preferably, the upper end of the sliding rod is fixedly connected to a connecting block, and the two connecting rods are hinged to the connecting block.

[0017] The above technical solution makes the connection between the connecting rod and the sliding rod more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following description is merely a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions based on the principles of the present invention should be included in the scope of protection of the present invention. It should also be noted that improvements and modifications that do not depart from the principles of the present invention by ordinary skill in the art should also be considered within the scope of protection of the present invention.

[0023] See Figures 1 to 3 , a limiting mechanism for paper tube cutting is provided with a frame 1, and a scale 9 is pasted on the upper side of the frame 1. With the scale 9 as a reference, the paper tube can be accurately cut into the required length. The upper part of one end of the frame 1 is slidably connected to two connecting seats 2, and the connecting seat 2 is rotatably connected to a runner 3. A gasket 8 is provided between the two connecting seats 2 to prevent the friction generated by the paper tube and the frame 1 when the paper tube rotates, which causes wear on the paper tube. The gasket 8 is pasted together with the frame 1, and also includes a connecting rod 4 and a sliding rod 5. There are two connecting rods 4, and the ends of the two connecting rods 4 are hinged to the two connecting seats 2 respectively. The side of the end of the frame 1 is fixedly connected with a sliding sleeve 6, and the sliding rod 5 vertically passes through the sliding sleeve 6 and is slidably connected to the frame 1. The other end of the two connecting rods 4 is hinged to the upper end of the sliding rod 5, and the sliding sleeve 6 is threadedly connected with a horizontal bolt 7. The head of the bolt 7 passes through the interior of the sliding sleeve 6 and contacts the sliding rod 5.

[0024] Working principle: put the paper tube on the supporting roller of the frame 1, and then move one of the connecting seats 2 close to the paper tube. The movement of the connecting seat 2 drives the sliding rod 5 to move vertically downward through the connecting rod 4 hinged thereto, and the moved sliding rod 5 drives the other connecting seat 2 to move close to the paper tube through another connecting rod 4, so that the wheels 3 of the two moving seats are in contact with the outer wall of the paper tube, and then tighten the bolt 7 to make it press against the sliding rod 5, thereby fixing the wheel 3. At the same time, multiple holes can be opened on the sliding rod 5, and a pin can be used to pass through the sliding sleeve 6. The distance between the wheels 3 is different, the height of the sliding rod 5 is different, and the pin is embedded in the different holes, thereby fixing the sliding rod 5, making it easy to adjust the distance between the two wheels 3, so that it can limit paper tubes of different diameters, prevent the paper tube from shifting left and right when cutting the paper tube, and at the same time avoid wear of the paper tube surface by the wheel 3; similarly, move the connecting seat 2 away from the paper tube, the sliding rod 5 rises, driving the other connecting seat 2 away from the paper tube, thereby separating the two wheels 3 from the paper tube.
