Description

Technical Field

[0001] The utility model relates to an auxiliary material for cigarette production, in particular to a tipping paper surface hardening joint. Background Art

[0002] In the cigarette factory's rolling process, the surface joint method of the tipping paper disc used is to use a self-adhesive certificate label to completely cover the tipping paper joint and paste it on the disc surface. One part of the certificate label is pasted on the outside of the tipping paper joint and the other part is pasted on the disc surface. Since the tipping paper joint is completely covered, there is no tail at the tipping paper joint. As a result, when the YF75 disc automatic changer is automatically splicing two tipping paper discs, its paper pick-up knife detector cannot recognize the tail at the tipping paper joint, resulting in the inability to automatically clamp the joint. Therefore, the current splicing method is: in the shutdown state, the manual splicing method is used to realize the manual splicing of two tipping paper discs. This splicing method is time-consuming and labor-intensive, increases the labor intensity of workers, has low splicing efficiency, and will also cause the equipment to stop for too long, affecting the effective operation of the equipment.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides a tipping paper surface hardened joint, which cancels the original method of using a label to fully cover the tipping paper surface joint and stick it on the paper disk surface, and adopts an adhesive glue layer to set an adhesive glue layer on the inner side of the tipping paper joint section, and relies on the adhesive glue layer to achieve the sticking of the tipping paper joint section and the paper disk surface of the tipping paper disk, and at the same time, the end of the tipping paper joint section is extended out of the end of the adhesive glue layer to form a trailing section, and the position of the label layer outside the tipping paper joint section is adjusted so that the trailing section of the tipping paper joint section is exposed from the end of the label layer, which is convenient for an automatic paper disk changing machine to accurately identify and smoothly clamp the joint, so that the automatic paper disk changing machine can realize the automatic splicing of two tipping paper disks, thereby improving the splicing quality and splicing efficiency, and reducing the equipment downtime caused by manual splicing.

[0015] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0016] See also Figure 1 to Figure 2 The present embodiment discloses a tipping paper surface hardened joint, wherein a tipping paper tray paper 1 is provided with a hardened joint at the end thereof, a section of the tipping paper located at the hardened joint is a tipping paper joint section 3, the hardened joint comprises a label layer 2, a tipping paper joint section 3 and an adhesive colloid layer 4 which are sequentially connected from the outside to the inside, the label layer 2 is a self-adhesive label layer 2, the hardened joint is bonded to the disk surface of the tipping paper tray paper 1 through the adhesive colloid layer 4, a section of the end of the tipping paper joint section 3 extends out from the end of the adhesive colloid layer 4 to form a trailing section 5, the end of the label layer 2 is located at the middle section of the trailing section 5 of the tipping paper joint section 3, and the label layer 2 can completely cover the adhesive colloid layer 4.

[0017] The adhesive layer 4 is a layered adhesive tape layer, which can not only meet the requirements of adhering the hardened joint to the disk surface of the tipping paper tray 1, but also can achieve separation without damaging the tipping paper.

[0018] The distance between the end of the trailing section 5 of the tipping paper joint section 3 and the end of the adhesive glue layer 4 is between 20 mm and 25 mm. The distance between the end of the trailing section 5 of the tipping paper joint section 3 and the end of the label layer 2 is less than 4 mm. The size of the adhesive glue layer 4 along the length direction of the tipping paper joint section 3 is 15 mm to 20 mm, and the size along the width direction of the tipping paper joint section 3 is greater than 50 mm and less than the width of the tipping paper joint section 3.

[0019] The hardened joint on the tipping paper surface provided in the present embodiment eliminates the original method of using a label to fully cover the tipping paper surface joint and stick it on the paper coil surface. Instead, an adhesive glue layer 4 is provided on the inner side of the tipping paper joint section 3, and the tipping paper joint section 3 is stuck to the paper coil surface 1 by relying on the adhesive glue layer 4. At the same time, the end of the tipping paper joint section 3 is extended out of the end of the adhesive glue layer 4 to form a tail section 5. At the same time, the position of the label layer 2 on the outer side of the tipping paper joint section 3 is adjusted so that the tail section 5 of the tipping paper joint section 3 is exposed from the end of the label layer 2, so that the tipping paper joint section 3 has a certain hardness and thickness and has the tail section 5 at the same time, so that the paper picking knife of the automatic paper coil changing machine can accurately identify and smoothly clamp the joint. After the paper picking knife clamps the joint, the tipping paper wrapped on the paper coil is opened by pulling the tail section 5, and the pulled paper tape passes through and enters the automatic paper coil changing machine, which is convenient for subsequent splicing operations. The problem that the automatic paper reel changing machine cannot automatically splice due to the lack of tailing of the tipping paper joint in the prior art is avoided, thereby ensuring the effective operation of the automatic paper reel changing machine equipment.

[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
