Novel glue-free roll tail sealing device

Abstract

The invention discloses a novel glue-free roll tail sealing device. The novel glue-free roll tail sealing device comprises a plurality of tail sealing mechanisms arranged side by side and a drive unit. Each tail sealing mechanism comprises a tail sealing clamp and a connecting unit. The drive unit is rotation shaft drive. The connecting units of the multiple tail sealing mechanisms are in transmission fit with the drive unit. The drive unit rotates in a reciprocating manner so as to drive the multiple connecting units to swing, and accordingly the corresponding tail sealing clamps are driven to be opened and closed along with swinging of the connecting units. Through the manner that the drive unit rotates in a reciprocating manner so as to drive the multiple connecting units to swing, thetail sealing clamps are opened and closed along with swinging of the corresponding connecting units, accordingly, coiling block clamping and tail sealing are achieved, and the effect that one drive unit drives the multiple tail sealing clamps to be opened and closed at the same time is achieved.

Description

technical field [0001] The invention relates to the production and processing equipment of roll materials, more specifically to the technical field of the production and processing equipment of toilet paper rolls, and in particular to a new type of glue-free sealing tail device. Background technique [0002] The reel is a roll-shaped material formed by winding the web-shaped material, and the common forms are toilet paper rolls, plastic rolls, etc. Taking the toilet paper roll as an example, in order to maintain the stability of the roll during packaging, transportation, etc., the existing roll needs to be sealed at the tail end of the roll so that it will not fall apart. The existing reel will be sealed with glue at the end after winding to maintain the stability of the reel. The sealing method with glue has the following three disadvantages: First, the reel must be glued before use. The process of tearing the tail will destroy the outer ring of the reel that is bonded to ...

Problems solved by technology

The existing reel will be sealed with glue at the end after winding to maintain the stability of the reel. The sealing method with glue has the following three disadvantages: First, the reel must be glued before use. The process of tearing the tail will destroy the outer ring of the reel that is bonded to the tail end, so that part of the tail end cannot be used normally; second, because the glue has a certain permeability, it tends to stick to the inner paper in some cases. The user needs to tear off multiple layers before using it, which not only wastes materials, but also is inconvenient to operate; thirdly, a large amount of glue is used in the existing reel end sealing, which not only needs to increase additional material costs, but also glue is a It is a kind of chemical synthetic material, which has certain harmful components and is volatile. It will have a negative impact on the health of workers or users, whether in the production process or in use, and the use of a large amount of glue is not conducive to environmental protection.

However, the applicant only discloses its processing method in this patent, and does not disclose the specific equipment for realizing the method.
