[0058] The working principle of the present application is as follows:

[0059] When the glue liquid in the glue feeding cylinder is used up, the old glue feeding cylinder is driven to move away from the valve body, so that the connecting needle mounted on the valve body is pulled out of the glue feeding flow channel on the glue feeding block mounted on the old glue feeding cylinder, at this time, the glue liquid remaining in the glue feeding flow channel will not overflow under the action of the elastic gasket, and the ball in the tapered through hole is in extrusion contact with the inner wall of the tapered through hole under the action of the spring to realize the rapid sealing of the flow channel in the glue feeding block, so that the overflow of the glue liquid in the glue feeding block can be avoided, and the stability and consistency of the glue liquid in the glue discharging flow channel before and after the replacement of the glue feeding cylinder can be maintained, thereby ensuring the consistency of the glue dispensing quality.

[0060] Then, the valve body is driven to move close to the new glue feeding cylinder, and the connecting needle thereon is inserted into the glue feeding flow channel through the elastic gasket on the new glue feeding cylinder, at the same time, the second magnet mounted on the valve body is attracted and fixed with the first magnet mounted on the glue feeding cylinder, so that the rapid connection between the valve body and the glue feeding cylinder is realized, and the stability of the connection is good, thereby improving the stability of the glue feeding from the glue feeding cylinder to the valve body and the glue dispensing of the valve body.

[0061] Next, the glue liquid in the new glue feeding cylinder flows towards the glue discharging flow channel, the ball in the tapered through hole moves and extrudes the spring under the pressure of the glue liquid, so that the glue discharging gap is formed between the ball and the inner wall of the tapered through hole, and the rapid communication of the internal glue flow channels of the glue feeding block on the new glue feeding cylinder and the glue feeding block on the valve body is realized.

[0062] When the detachable glue feeding mechanism is used, the glue feeding cylinder and the glue valve can be quickly connected and detached, so that the glue feeding cylinder can be quickly replaced. During the connection and disconnection of the glue feeding cylinder, the glue liquid flow channel in the glue feeding block on the valve body can be quickly connected with the glue feeding block on the new glue feeding cylinder, the overflow of the residual glue liquid in the old glue feeding cylinder can be effectively avoided when the valve body is separated from the old glue feeding cylinder, and the flow channel in the glue feeding block on the valve body can be quickly cut off when the valve body is separated from the old glue feeding cylinder. Therefore, the overflow of the glue liquid in the glue feeding block can be avoided, the stability and consistency of the glue liquid in the glue outlet flow channel before and after the replacement of the glue feeding cylinder can be maintained, and the consistency of the glue dispensing quality can be ensured.

[0063] In addition, while facilitating the disconnection and replacement of the glue feeding cylinder connected with the valve body, the valve body and the glue feeding cylinder are quickly connected, and the connection stability is good, so that the stability of the glue feeding cylinder to the valve body and the glue dispensing of the valve body is improved.
