Description

Technical Field

[0001] The utility model belongs to the technical field of sanitary roll production and relates to a paper-core-free sanitary roll production system. Background Art

[0002] One of the existing toilet roll production processes is to add a hard paper core during toilet roll production to facilitate the manufacture of toilet roll paper. For example, CN202046736U discloses a coreless toilet roll production line system, which uses a fiber stick to wind toilet paper around a fiber stick. The fiber stick is then pulled out of the middle by a power structure to achieve the production of a paper-free toilet roll. The fiber stick can be reused. This technical solution can avoid the waste of hard paper cores in the existing technology. However, in actual production, the fiber stick in the above technical solution is difficult to pull out from the toilet roll easily, which can easily cause damage to the toilet roll.

DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be derived from these drawings without inventive effort.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the embodiments of the present invention are not limited to the following embodiments.

[0021] Combine Figure 1-Figure 3 As shown, the utility model provides a paper-coreless toilet roll production line system, which includes a conveying unit 1, a winding unit 2 located on the left side of the conveying unit 1, and a cutting unit 3 located on the upper side of the conveying unit 1.

[0022] In the paper-core-free sanitary roll production line system of the present invention, the winding unit 2 is used for winding and forming the sanitary roll, the cutting unit 2 is used for cutting the sanitary roll into a set size, and the conveying unit 1 is used for conveying the cut sanitary roll for subsequent packaging processing.

[0023] In one embodiment of the present invention, the winding unit 2 includes a rotating motor 21 and a rotating shaft 22 connected to the rotating motor 21. A first mounting hoop 23 and a second mounting hoop 24 are fixedly disposed on the rotating shaft 22 at intervals. A sliding plate 25 is also slidably mounted on the rotating shaft 22. The first mounting hoop 23, the second mounting hoop 24, and the sliding plate 25 are connected to an adjustable winding frame 4. In this embodiment, the adjustable winding frame 4 includes a first articulated frame 41, a second articulated frame 42, and a third articulated frame 43, which are respectively hinged to the first mounting hoop 23, the second mounting hoop 24, and the sliding plate 25. Multiple first articulated frames 41, 42, and 43 are provided, and the multiple first articulated frames 41, 42, and 43 are evenly spaced radially along the rotating shaft 22. The first articulated frames 41, 42, and 43 at the same angle form an installation group, which is mounted with a connecting frame 44, and a curved support plate 45 is fixed to the connecting frame 44.

[0024] In this embodiment, a mounting plate 26 is fixed to the rotating shaft 22 , and a driving device 27 is mounted on the mounting plate 26 . The driving device 27 is fixedly connected to the sliding plate 25 and is used to drive and adjust the winding frame 4 to tighten or expand.

[0025] The paper core-free sanitary roll production line system of the present invention, through the above-mentioned structural arrangement, can drive the movement of the sliding plate 25 by the driving device 27 to realize the opening or contraction of the arc-shaped support plate 45. Therefore, in specific production, the arc-shaped support plate 45 can be first placed in an open state to carry out the winding of the toilet paper. After the toilet paper is wound into a roll, the arc-shaped support plate 45 is restored to the contracted state to achieve separation from the sanitary roll, avoiding the problem in the prior art that the paper core is difficult to pull out of the sanitary roll.

[0026] In addition, the paper-coreless toilet roll production line system of the present invention has a base 5 disposed below the adjustable winding frame 4, on which is disposed a support platform 6 having a curved support surface 7. With the aforementioned arrangement of the support platform 6, the distance between the support platform 6 and the adjustable winding frame 4 can be adjusted according to actual needs. Furthermore, when the toilet roll is wound to a certain thickness according to the setting, the curved support plate 45 is retracted, thereby supporting the toilet roll on the curved support surface 7.

[0027] In this embodiment, the base 5 further includes an adapter plate 51, on which the rotary motor 21 is mounted. A drive cylinder 8 is also mounted on the adapter plate 51. The drive cylinder 8 is located below the rotary motor 21. A push block 81 is connected to the front end of the drive cylinder 8. The drive cylinder 8 pushes the push block 81 to move along the arcuate support surface 7. With this arrangement, when the sanitary roll is supported on the arcuate support surface 7, the drive cylinder 8 pushes the push block 81 to push the sanitary roll toward the cutting unit 3.

[0028] According to one embodiment of the present invention, the conveying unit 1 includes a support structure 11 and a conveyor belt 12. The conveyor belt 12 is located below the arc-shaped support surface 7, and the base 5 is fixedly connected to the support structure 11. The cutting unit 3 includes a gantry 31, a motor 32 mounted on the gantry 31, and a blade 33 connected to the motor 32.

[0029] In the paper-coreless sanitary roll production line system of the present invention, the pushing block 81 pushes the sanitary roll toward the cutting unit 2, and the blade 33 is used to cut the sanitary roll. The cut sanitary roll is transported backward by the conveyor belt 12 for packaging.

[0030] The above description is merely one embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
