Description

Technical Field

[0001] The invention relates to the technical field of papermaking auxiliary equipment, in particular to a parent roll tail sealing glue spraying device with a self-cleaning function. Background Art

[0002] The post-processing of papermaking involves processes such as curling and rewinding. In these processes, roll changing is required, that is, the paper web is continuously wound onto the reel roller in contact with the surface of the reel roller through the reel cylinder to form a parent roll. When the parent roll reaches the specified diameter, a new reel roller is pressed down to contact the surface of the reel cylinder. The paper machine then separates the continuous paper web from the parent roll through the reel changing device and winds it onto a new reel roller.

[0003] During the roll changing process, the tail of the mother roll needs to be sprayed with glue. For example, a water-jet roll changing dovetail edge glue spraying device disclosed in the Chinese patent document with publication number: CN216917947U includes a mounting frame, a telescopic cylinder, a middle plate fixed in the middle of the mounting frame, a fixed connecting rod frame fixed on the middle plate, a first connecting rod and a second connecting rod rotatably connected to the fixed connecting rod frame, a movable connecting rod frame, an extension rod fixedly connected to the output end of the first connecting rod, and a glue spraying nozzle assembly connected to the end of the extension rod; the output ends of the first connecting rod and the second connecting rod are both rotatably connected to the movable connecting rod frame, the fixed connecting rod frame is rotatably connected to the middle of the first connecting rod, and the telescopic end of the telescopic cylinder is connected to the input end of the first connecting rod. This technical solution uses the water needle roll-changing dovetail edge spraying devices on both sides of the paper reel to spray glue on the dovetail paper cut from the paper reel at the same time, so that the dovetail sticks to the mother roll as it continues to rotate with the mother roll. On the one hand, the dovetail will not swing around and break, and on the other hand, after the dovetail is pasted on the mother roll, the mother roll can be kept from being loosened. This further explains that in the current mother roll tail sealing, the nozzle is mainly used for spraying glue. After the nozzle completes the spraying action, glue residue will appear at the nozzle. Although the above document uses an air jet to blow off the residual glue at the nozzle position, some glue adheres to the nozzle position and solidifies when used for a long time, and the nozzle needs to be cleaned manually, which affects the processing efficiency and the quality of the glue spraying. In addition, when it is used, the position of the air jet nozzle is fixed, which is not easy to adjust and has poor applicability. Summary of the invention
