Description

Technical Field

[0001] The utility model relates to the technical field of rolling, in particular to a rolling device for a convenient environmentally friendly bag. Background Art

[0002] Winding is one of the steps in plastic processing. It refers to a process of heating and melting plastic particles and then blowing them into a film and then winding them up. When blowing film, the polymer is usually extruded into a tubular film blank. Under a good melt flow state, the tubular film is blown up to the required thickness by high-pressure air. After cooling and shaping, it becomes a film. After that, the winding device can be used to wind up the produced film.

[0003] In the prior art, for example, the plastic bag reeling device with Chinese patent number CN210914570U includes: a base, a first support column, a second support column and a fixing mechanism; the second support column is fixed on the base, the first support column is slidably arranged on the base, the first support column and the second support column are coaxially arranged with fixing mechanisms on the opposite sides of the ends to fix the reeling shaft, and the second support column is also provided with a driving motor, which drives the fixing mechanism on the second support column to rotate through a transmission mechanism, and the fixing mechanism on the first support column can also rotate by itself; wherein the fixing mechanism includes: a support shaft and a baffle arranged on the support shaft. The plastic bag reeling device overcomes the problem that the continuous roll bag making machine in the prior art needs to manually pull out the wound plastic bag together with the reel from the support shaft after the reeling is completed, and this continuous roll plastic bag reeling method has low working efficiency.

[0004] Although the above scheme has the above technical advantages, the disadvantage is that during the rolling process, air may remain inside the plastic bag. If the air in the bag is not discharged, as the thickness of the bag roll becomes thicker during rolling, the remaining air in the bag will form a bulge because it cannot be discharged. It is very likely that the bag film will be broken during the rolling process, thereby causing product damage. Utility Model Content

The inner surface of the rotating sleeve 20 is rotatably connected to the outer surface of the rotating frame 18. The outer surface of the guide roller 5 is rotatably connected to the inner surface of the fixed plate 2. The inner surface of the fixed plate 2 is rotatably connected to the outer surface of the rotating frame 18. The outer surface of the output end of the first motor 3 is rotatably connected with a belt 6. The inner surface of the belt 6 is rotatably connected to the outer surface of the reel 4. The outer surface of the rotating sleeve 20 is fixedly connected with a fixed column 25. The outer surface of the fixed column 25 is slidable. The hollow screw 23 is movably connected, and the outer surface of the hollow screw 23 is threadedly connected with an annular sleeve 22. The outer surface of the annular sleeve 22 is slidably connected to the inner surface of the sleeve 24. The outer surface of the sleeve 24 is rotatably connected to the inner surface of the frame 1. The inner surface of the sleeve 24 is rotatably connected with a knob 26. The outer surface of the knob 26 is fixedly connected to the outer surface of the hollow screw 23. The lower surface of the annular sleeve 22 is fixedly connected to the top of the compression spring 21. The film after film blowing passes between the two guide rollers 5 rotatably connected to the frame 1 and is fixed to the surface of the reel 4. The first motor The belt 6 drives the reel 4 to rotate and the film is wound. During this process, the position of the annular sleeve 22 can be adjusted by rotating the knob 26, and the knob 26 drives the hollow screw 23 to rotate together. At this time, the annular sleeve 22 slides downward in the sleeve 24, and the fixed column 25 slides in the hollow screw 23. During this process, the pressing spring 21 is compressed and presses the rotating frame 18 downward through the rotating sleeve 20, so that the pressing roller 19 rotatably connected to the rotating frame 18 always presses the film on the surface of the reel 4 and discharges the air in the film during the winding process.

Under the elastic force of the compression spring 12, the surface of the shearing wheel 14 is always in contact with the surface of the upper shearing wheel 15, thereby preventing the lower shearing wheel 14 and the upper shearing wheel 15 from failing to completely cut the film during movement. After cutting, the rolled film can be taken down from the surface of the reel 4 through the opening of the fixed plate 2.

[0023] Working principle:

[0024] When in use, the film after film blowing is passed between the two guide rollers 5 rotatably connected to the frame 1 and fixed on the surface of the reel 4. The first motor 3 drives the reel 4 to rotate through the belt 6 to reel the film. During this process, the position of the annular sleeve 22 can be adjusted by rotating the knob 26. The knob 26 drives the hollow screw 23 to rotate together. At this time, the annular sleeve 22 slides downward in the sleeve 24, and the fixed column 25 slides in the hollow screw 23. During this process, the clamping spring 21 is compressed and presses the rotating frame 18 downward through the rotating sleeve 20, so that the clamping roller 19 rotatably connected to the rotating frame 18 always presses the film on the surface of the reel 4, and discharges the air in the film during the reeling process to prevent air from remaining inside the film after reeling. At the same time, it can also prevent the film from having gaps during reeling, resulting in local relaxation.

[0025] After the winding is completed, the second motor 9 drives the upper screw 7 and the lower screw 10 to rotate at a constant speed through the synchronous belt 8. At this time, the lower fixed frame 11 and the upper fixed frame 17 move at a constant speed, so that the upper shearing wheel 15 rotatably connected to the upper wheel frame 16 and the lower shearing wheel 14 rotatably connected to the lower wheel frame 13 move synchronously to cut the film. Under the elastic force of the compression spring 12, the surface of the shearing wheel 14 is always in contact with the surface of the upper shearing wheel 15, thereby preventing the lower shearing wheel 14 and the upper shearing wheel 15 from failing to completely cut the film during movement. After cutting, the wound film can be taken down from the surface of the reel 4 through the opening of the fixed plate 2.
