[0032] When replacement is required, the rubber supply cylinder, the rubber supply block and the support seat are removed from the opposite direction of the connecting block, and then the rubber cylinder to be replaced is removed and replaced with a new rubber cylinder.

[0041] The working principle of the utility model is as follows:

[0042] When replacement is required, move the old glue supply cylinder in the opposite direction of the valve body, separate the glue supply block from the connection block, and separate the glue inlet connector from the ball;

[0043] In this process, the ball is squeezed into contact with the slope surface of the inner wall of the through hole under the action of the spring to quickly cut off the entire glue supply channel;

[0044] Afterwards, the new glue supply cylinder is moved toward the valve body, the glue supply block is connected to the connecting block, the glue feed connecting piece is inserted into the through hole on the glue supply connecting piece and is squeezed into contact with the ball, and the ball moves toward the spring direction under the push of the glue feed connecting piece and squeezes the spring, thereby forming a gap between the ball and the slope surface of the inner wall of the through hole that connects the transition flow channel and the glue supply flow channel on the glue supply block, thereby realizing rapid connection between the glue supply block on the new glue supply cylinder and the internal glue flow channel of the glue feed block on the valve body.

[0045] When the above-mentioned integrated dispensing unit is adopted, it can realize the rapid disassembly and connection between the dispensing valve body and the glue supply cylinder to facilitate the replacement of the glue supply cylinder to continuously supply glue to the valve body, and in the process of replacing the glue supply cylinder, it can realize the rapid connection between the glue inlet block on the valve body and the internal glue flow channel of the glue supply block on the new glue supply cylinder, and when the valve body is separated from the old glue supply cylinder, the internal flow channel of the glue supply block on the old glue supply cylinder can be quickly cut off, thereby avoiding waste caused by glue overflow and damage to the dispensing product.
