Gluing machine glue spraying system

Abstract

The invention provides a gluing machine glue spraying system. The system comprises a glue outlet part and a glue storage part, the glue outlet part comprises a bottom plate, a motor is arranged on thelower portion of the bottom plate, the motor is connected with a screw, the outer side of the screw is provided with a moving block, a glue cylinder and an ejecting block through an adjusting sleeve,the ejecting block is provided with a control cavity, an ejecting block glue outlet and an ejecting block glue inlet, the bottom of the ejecting block is provided with a pneumatic valve, the glue storage part comprises a glue melting bucket, the bottom of the glue melting bucket is provided with a bottom disc, the bottom disc is provided with a glue bucket glue outlet, the glue melting bucket isprovided with a bucket cover and a movable bolt, the bucket cover is provided with a pneumatic joint, the glue melting bucket and the rubber cylinder are arranged to be of a closed structure, yellowing caused by the fact that a large amount of glue makes contact with air can be avoided, due to the closed type glue melting bucket, the glue melting speed is high, the customer waiting time is reduced, meanwhile, through cooperation of a moving block and the glue cylinder, the size of a glue outlet of the glue cylinder can be freely adjusted, the system is suitable for various book thicknesses, and the pneumatic valve is used for flexibly controlling the opening and closing of glue spraying.

Description

technical field [0001] The invention relates to the technical field of glue binding machines, in particular to a glue spraying system for glue binding machines. Background technique [0002] The glue binding machine is to bundle the semi-finished book stickers, put a certain number of book stickers on the strapping machine, use the two ends to block quickly, start the strapping machine, compact the loose book stickers and then tie them with rope belts . In order to make the compacted back stiff and tidy, after compacting and binding, paint the back of the bound book with polyethylene glue. After the brushed polyvinyl alcohol glue is dry, loosen the tie rope, and then put it on the back of the book. Separate each book and transfer it to a plastic bag. [0003] The traditional adhesive machine adopts an open glue tank, and uses the rubber wheel to roll the glue. This design has the following defects: the open glue tank, the heat dissipation is fast, and the melting speed is ...

AI Technical Summary

Problems solved by technology

[0004] The present invention proposes a glue spraying system for a glue binding machine to solve the problem that the traditional glue binding machine proposed in the above background technology uses an open glue tank, and the open glue tank has faster heat dissipation and generally slower melting speed, which causes users to use It takes a long time to wait for the glue to melt, and the glue in the open glue tank is in contact with the air, which is easy to oxidize and change color, which affects the effect of glue binding and other problems.
