High-speed glue-free tail sealing device and working method thereof

Abstract

The invention discloses a high-speed glue-free tail sealing device. The high-speed glue-free tail sealing device comprises at least two groups of tail sealing units; the tail sealing units are sequentially arranged in the rolling and feeding direction of drums in a front and back manner; the multiple drums continuously fed are classified according to a sequential order based on the number of the tail sealing units; and the drums in the same group are correspondingly rolled and fed to the each group of tail sealing units for lamination and tail sealing according to the sequential order. The twodrums in the same group are subjected to the lamination and the tail sealing through the first tail sealing units and the second tail sealing units which are arranged in a front and back manner, double-station and double-drum tail sealing operation is achieved, and an empty window waiting cycle between tail searching adjustment treatment, and lamination and tail sealing operation is reduced, so that the production efficiency is further improved substantially, and the working procedure is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of production and processing of roll materials, in particular to a high-speed glue-free tail sealing device and its working method. Background technique [0002] In the production of existing tissue paper, it is generally necessary to seal the end of the paper roll after rewinding. There are two commonly used sealing methods: the first method is to use Adhesive (such as glue, etc.) is applied to the end of the paper roll to achieve adhesive sealing. However, this method of gluing and sealing has problems such as large amount of useful glue, environmental protection, and high production costs; the second method is through non-adhesive sealing. The tailing device performs mechanical clamping and sealing on the paper roll, such as a roll glueless tail sealing device (notification number CN1065866B) applied by the applicant, which presses the outer peripheral surface of the roll through the tail sealing clamp to...

Problems solved by technology

[0002] In the production of existing tissue paper, it is generally necessary to seal the end of the paper roll after rewinding. There are two commonly used sealing methods: the first method is to use Adhesive (such as glue, etc.) is applied to the end of the paper roll to achieve adhesive sealing. However, this method of gluing and sealing has problems such as large amount of useful glue, environmental protection, and high production costs; the second method is through non-adhesive sealing. The tailing device performs mechanical clamping and sealing on the paper roll, such as a roll glueless tail sealing device (notification number CN1065866B) applied by the applicant, which presses the outer peripheral surface of the roll through the tail sealing clamp to form a pressure seal. The joint part, and before pressing the reel, the reel is squeezed to form a protrusion at the opening of the sealing clamp die. This method is used to ensure the stability of the glueless sealing process.

[0003] The processing efficiency of the existing glueless tail sealing machine is generally 20-30 paper rolls per minute, and now the glueless tail sealing machine generally adopts the single-station pressing and sealing method, that is, by setting The single-group tail-sealing unit presses and seals the fed paper rolls one by one, and when the previous paper roll is pressed and sealed, the next paper roll is rolled to the upstream preset paper tail orientation mechanism Carry out paper tail orientation processing, and then finish pressing and sealing the previous paper roll, and then roll the next paper roll to the tail sealing unit by the paper tail orienting mechanism, and this cycle constitutes the existing pressure sealing The continuous production process of tails, and the glueless tail sealing machine adopting this strip-by-strip tail sealing method takes a lot of time in the process of paper tail orientation processing and paper roll rolling, which affects the processing efficiency
