As shown in fig. 1 to 5, an embodiment of the present utility model provides a glue shut-off valve including a valve body 1, an elastic return portion 2, and a ball valve core 3.

Wherein, a hollow cavity 10 is arranged in the valve body 1, and a glue inlet 110 and a glue outlet 120 which are communicated with the hollow cavity 10 are arranged on the outer wall of the valve body 1; one end of the elastic return part 2 is fixed at the bottom of the hollow cavity 10; the ball valve core 3 is located at the other end of the elastic return portion 2, and is configured to abut against and block the glue inlet 110 under the pushing of the elastic force of the elastic return portion 2.

According to the glue stop valve provided by the embodiment of the utility model, the ball valve core 3 connected with the elastic return part 2 is abutted against and blocks the glue inlet 110, so that when enough pressure is applied to the ball valve core 3 by glue through the glue stop valve, the ball valve core 3 compresses the elastic return part 2 under the action of the pressure, and the glue can enter the hollow cavity 10 from the space between the removed ball valve core 3 and the glue inlet 110 and be discharged from the glue outlet 120. When a container such as a glue supply sleeve which is in butt joint with the glue inlet 110 of the glue stop valve and used for storing glue is disconnected and butt joint, the pressure acting on the ball valve core 3 is eliminated, and the ball valve core 3 can be in butt joint again and block the glue inlet 110 under the action of the restoring original long return stroke of the elastic return stroke part 2, so that the gap between the surface of the ball valve core 3 and the glue inlet 110 is closed, the function of preventing the glue from flowing back and overflowing is achieved, the waste of the glue is avoided, and the adverse phenomena that the activity of the glue is reduced and the glue overflowed to the outside is caused by the phenomenon that the glue is adhered and the like are prevented. Therefore, after the glue in the containers such as the glue supply sleeve is completely discharged to the glue transmission pipeline to be exhausted, operators can conveniently withdraw the glue supply sleeve from the glue supply equipment, and the glue in the glue supply sleeve is replenished or replaced by a new glue supply sleeve. In addition, the glue stop valve provided by the embodiment of the utility model is realized by a simple structure with fewer components, has low production cost, is beneficial to mass production, and improves the universality of the glue stop valve.

Specifically, the valve body 1 is rectangular, the glue inlet 110 is located at the top 11 of the valve body 1, and the glue outlet 120 is located on the side 12 of the valve body 1. By using the arrangement of the top-down valve body transmission channel from the glue inlet 110 to the glue outlet 120, the elastic return part 2 stretches up and down in the vertical direction, the ball valve core 3 is abutted under the glue inlet 110, and meets the requirement that the opening of the container such as the glue supply sleeve is positioned under the container so as to be vertically arranged on the glue supply equipment.

As shown in fig. 6, in an exemplary embodiment, the glue stop valve provided in this embodiment has a multi-channel stop valve structure, the number of the glue outlets 120 is plural, and the glue outlets 120 are distributed on each side 12 of the valve body 1 in a one-to-one correspondence manner. Glue delivery of a plurality of glue supply pipelines connected with the glue outlets 120 one by one can be realized by one glue stop valve.

In order to meet the glue supply requirements of different scenes, glue outlet ports of different models are adapted, the aperture of each glue outlet port 120 is different, and the glue outlet ports 120 are threaded holes.

As shown in fig. 4, further, the hollow cavity 10 of the valve body 1 is sleeved with a valve core mounting base 13, the valve core mounting base 13 includes a chassis 131 fixed on the inner wall of the valve body 1 by screw locking and a hollow cylinder 132 standing above the chassis 131, and one end of the elastic return portion 2 fixed on the bottom of the hollow cavity 10 is connected to the chassis 131 of the valve core mounting base 13 and is accommodated in the hollow cylinder 132. Therefore, the elastic return part 2 and the ball valve core 3 on the valve body 1 can be easily disassembled, and the maintenance is convenient.

For the glue outlet 120 corresponding to a plurality of different aperture types, a plurality of corresponding openings are formed on the side wall of the hollow cylinder 132.

The ball valve core 3 should be made of an anti-adhesive material, and in view of structural stability, reliability, cost and the like, the ball valve core 3 is illustratively a steel ball. The elastic return part 2 is a telescopic spring, is a more common and reliable elastic component, and has smaller size so as to adapt to the requirement of the glue stop valve.
