Description

Technical Field

[0001] The invention belongs to the technical field of towel rolling machines, and particularly relates to a paper tube outer towel rolling machine. Background Art

[0002] As daily consumables, towel rolls are widely used in life. During the processing of towel rolls, towel roll machines are needed for rolling, cutting and unloading.

[0003] However, when the current towel rolling machine is working, the paper tube can only be put on the air shaft first, and then the cotton towel can be rolled directly on the paper tube. Such a towel rolling machine has the following defects: 1. The head end of the cotton towel is not easy to be fixed on the smooth paper tube. Now the head end is generally glued to the paper tube with glue, which will cause the last piece of cotton towel to be unable to be used completely. To solve the above problems, China authorized a utility model patent: an air blowing and cutting device for roll paper towel production, which proposed "guided air blowing by a blowing mechanism to introduce the paper towel cutting head into the middle of the paper roll lower pressure roller and the air shaft to complete the initial paper rolling", but the roughness of the paper tube is required to be high, otherwise there is still a problem of slipping; 2. When the cotton towel is rolled directly on the paper tube, the cotton towel and the paper tube will be pressed tightly, so that the paper tube is difficult to remove, which also causes the cotton towel to be used only from the outside end. When used from the outside end, the cotton towel is easy to loose and unsightly. Summary of the invention

[0025] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below.

[0026] Working principle: When in use, the paper tube is put on the cotton rolling air shaft 7 at the upper tube station 8 from the upper tube mechanism 3, and is sleeved on the upper paper tube tensioning part 20. Because the diameter of the cotton rolling part 19 is larger than the diameter of the upper paper tube tensioning part 20 after sleeve, the paper tube is blocked and positioned by the cotton rolling part 19, and then the cotton rolling air shaft 7 is inflated and the key bar is propped up to support and position the paper tube. When the multi-station turntable 2 drives the cotton rolling air shaft 7 to rotate, when the cotton rolling air shaft 7 rotates to the rolling and cutting station 9, the cotton towels with the same number and width as the paper tube are wound on the cotton rolling part 19 of the cotton rolling air shaft 7 through the rolling and cutting mechanism 4 and cut off. Due to the effect of the long groove 21, the blowing mechanism of the rolling and cutting mechanism 4 guides the blowing to introduce the cut-off head of the cotton towel onto the cotton rolling air shaft 7, which is not easy to slip when winding. After rolling and cutting, the cotton rolling air shaft 7 is driven to the cotton rolling labeling station 10 through the multi-station turntable 2, and the cotton rolling air shaft 7 is driven to the cotton rolling labeling station 10 through the cotton rolling. The labeling mechanism 5 presses the end of the cotton towel after the cut and rolled, completes the winding and labels it, and then the multi-station turntable 2 rotates again to rotate the cotton roll inflatable shaft 7 to the unloading station 11. When the cotton roll inflatable shaft 7 is in place, the third cylinder 17 drives the fork member 18 to insert into the rear end of the cotton roll part 19 of the cotton roll inflatable shaft 7, and then the first cylinder 14 drives the slide 15 to slide forward, and then the fork member 18 synchronously pushes the cotton roll on the cotton roll part 19 onto the paper tube at the upper paper tube tensioning part 20, and then the cotton roll inflatable shaft 7 stops inflating and the key strip retracts the key groove, and then the second cylinder 16 drives the third cylinder 17 to continue to slide forward, and pushes the cotton roll with the paper tube on the cotton roll inflatable shaft 7 to the front receiving plate 30 through the fork member 18. At the same time, when the multi-station turntable 2 rotates, the cotton roll inflatable shafts 7 at different stations can work synchronously and circulate, thereby improving production efficiency.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
