Description

Technical Field

[0001] The utility model belongs to the technical field of rewinding machines, and particularly relates to a sticker tail device for a high-speed rewinding machine. Background Art

[0002] Rewinding machines are often used to slit wide-width coils, which play an important role in subsequent re-slitting, and are special equipment for paper, mica tape, and film.

[0003] The utility model with the publication number CN208120349U provides a cutting and glue spraying mechanism for a rewinding machine. In this utility model, the cutter assembly is rotated 180 degrees from the inner side of the side plate to the outer side of the side plate, and then a glue spraying assembly is arranged between the outer side of the side plate and the small finished product reel. In this way, when the cutter assembly cuts the continuously conveyed paper and applies glue to the paper, the glue oozing from the paper will directly fall to the ground instead of falling onto the side plate, thus ensuring the quality of the production of the next roll of paper and also avoiding the irregular cleaning of the side plate by the operator.

[0004] However, in the use of the above-mentioned utility model, after the paper web is slit, it is impossible to accurately avoid the knife gap position during glue spraying, which may cause the sprayed glue to pass through the knife gap to the other side of the paper web, resulting in the paper web sticking to the bottom roller in the subsequent process and affecting the smooth progress of the rewinding operation. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a sticker tail device for a high-speed rewinding machine to solve the problems raised in the above background art.

A gap for the paper web to pass through is left between the front bottom roller and the rear bottom roller. A paper roller driving mechanism is arranged above the front bottom roller and the rear bottom roller on the frame. The paper roller driving mechanism is connected to a paper roller. It is characterized in that a paper cutting mechanism is installed on the frame. The paper cutting mechanism is located below the rear bottom roller. The paper cutting mechanism is provided with a paper cutting knife that can be telescopically moved to the gap between the front bottom roller and the rear bottom roller. The frame is hinged with a finished product roll pushing arm. A pushing roll driving mechanism is connected between the finished product roll pushing arm and the frame.

[0011] As an improvement, the middle part of the finished roll pushing arm is hinged to the frame. One end of the finished roll pushing arm is the hinge end, and the other end is the pressing end.

After the glued paper is transported to the paper roll pushing position, paper cutting is performed. Then, under the action of the pushing arm small roller, the paper is firmly adhered to the paper roll, realizing the operation of sticking the paper tail. The operation is safe and the production efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In this embodiment, the glue spraying mechanism 9 includes a glue machine 24. The glue machine 24 is installed in a pit. The glue machine 24 is connected to a glue pipe, and the glue pipe is connected to a glue gun 6. The glue gun 6 is fixedly connected to the top of the mounting frame 15. The glue machine 24 is connected to an air pipe, and an air pipe solenoid valve is provided on the air pipe. The air pipe solenoid valve is connected to a controller. The controller can control the opening and closing of the air pipe solenoid valve according to the received electrical signal, thereby controlling the glue spraying time and timing of the glue gun 6, so that the glue material can be accurately sprayed to the position where the paper web needs to be sprayed.

[0031] In this embodiment, the moving mechanism 8 is provided with a drag chain bridge 18. The drag chain bridge 18 is fixedly connected to the bracket 14. A drag chain 16 is provided on the drag chain bridge 18. One end of the drag chain 16 is fixedly connected to the drag chain bridge 18, and the other end of the drag chain 16 is fixedly connected to the mounting frame 15. The drag chain 16 is fixedly connected to the glue pipe. The drag chain 16 prevents the glue pipe from being worn or bent during movement, affecting the normal use of the glue machine 24.

[0032] In actual use, the moving mechanism 8 can be provided with two sets of sliders 20, linear motors, linear encoders 25 and rail clamps 21. The two sets of sliders 20 are respectively equipped with glue spraying mechanisms 9. The two sets of glue spraying mechanisms 9 spray glue simultaneously to improve the glue spraying efficiency.

[0033] In this embodiment, the end of the finished product roll pushing arm 3 is hinged to the frame 7, and the other end is hinged to the pushing arm small roller 10. The driving mechanism of the pushing arm small roller 10 is a hydraulic cylinder 2. One end of the hydraulic cylinder 2 is hinged to the finished product roll pushing arm 3, and the other end is hinged to the hinged end of the pushing arm small roller 10. A pressing plate 27 is provided below the pushing arm small roller 10, and a cylindrical pressing rod 26 is provided at the end of the pressing plate 27.

[0034] The specific working process of this embodiment is as follows:

[0035] Specifically, the controller can issue a glue spraying instruction according to the rewinding situation of the paper roll or receiving a manual glue spraying instruction, causing the front bottom roller 4 and the rear bottom roller 11 to stop rotating, the moving mechanism 8 and the glue spraying mechanism 9 to operate, and perform moving glue spraying. At this time, the paper cutting knife 12 is in the initial position. After the glue spraying is completed, the moving mechanism 8 is controlled to return to the original position, the glue spraying mechanism 9 stops operating, the front bottom roller 4 and the rear bottom roller 11 operate, and the glued paper web runs backward to the rear bottom roller 11 and passes through the gap between the rear bottom roller 11 and the front bottom roller 4. After the glue spraying point passes a certain distance from the paper cutting point, it stops operating. The paper cutting knife 12 rotates and rises, and the glue roller presses the paper against the rear bottom roller 11. Then, the movement of the finished paper pushing arm is controlled, and the pushing arm small roller 10 follows, and the finished product roll 1 is pushed out. Under the combined action of the paper cutting knife 12 and the pushing arm small roller 10, paper cutting is achieved.

[0036] The utility model realizes uniform glue spraying through the cooperation of the moving mechanism 8 and the glue spraying mechanism 9. The position signal fed back by the cutting knife to the controller controls the operation of the moving and glue spraying mechanism 9, so that the glue spraying position accurately avoids the knife seam, preventing the glue from falling onto the other side of the paper during glue spraying and causing the paper web to stick to the bottom roller. After the sprayed paper passes a certain distance through the paper cutting point, the finished product roll pushing arm 3 operates to cut the paper. Then, under the action of the small roller 10 of the pushing arm, the paper is firmly adhered to the paper roll. This system can significantly improve production efficiency, reduce labor costs, reduce paper waste, eliminate safety hazards, and ensure the pasting quality at the same time.

[0037] The specific implementation manners of the utility model described above do not constitute a limitation on the protection scope of the utility model.
