[0021] When installation is required, the connecting needle is installed in the mounting hole of the connecting block, and then the tapered portion of the connecting needle is aligned with the avoidance through hole of the pressing block and passes through the elastic gasket to connect with the glue supply channel. During this process, the ball in the tapered through hole is squeezed and contacted with the inner wall of the tapered through hole under the extrusion of the spring, which can achieve rapid disassembly and positioning installation, facilitate replacement, and prevent glue from entering the flow channel hole, thereby avoiding glue overflow during installation.

[0028] Embodiment 2: A plug-in glue flow channel connecting component, comprising: a glue supply block 1 installed on a glue supply mechanism and a connecting block 2 installed on a glue dispensing valve, the upper end of a vertical section 31 of a glue supply flow channel 3 provided on the glue supply block 1 is used to connect with a glue outlet of the glue supply mechanism, a horizontal section 32 of the glue supply flow channel 3 extends in a direction close to the connecting block 2 opposite to one end of the vertical section 31, an elastic gasket 5 is sealed and installed on the glue supply block 1 and located on the outer side of the horizontal section 32 of the glue supply flow channel 3, a mounting hole 6 connected to the connecting flow channel 4 is provided on the side end surface of the connecting block 2 with a connecting flow channel 4 facing one end of the glue supply block 1, one end of a connecting needle 7 is embedded and installed in the mounting hole 6 and a flow channel hole 10 is provided on the end surface of the connecting needle 7 located in the mounting hole 6, the connecting A transition channel 71 with an inner diameter smaller than that of the channel hole 10 is provided between the other end of the connecting needle 7 and the channel hole 10. The transition channel 71 is connected to the channel hole 10 through a tapered through hole 11. A nut 12 with a central through hole 121 is installed at one end of the channel hole 10 opposite to the transition channel 71. A spring 14 in an extrusion state is horizontally arranged between the end face of the nut 12 and a sphere 13 arranged in the tapered through hole 11, so that the sphere 13 with a diameter larger than the inner diameter of the transition channel 71 can be extruded and contacted with the inner wall of the tapered through hole 11. When the end of the connecting needle 7 away from the mounting hole 6 passes through the elastic gasket 5, one end of the transition channel 71 is connected to the glue supply channel 3 on the glue supply block 1. When in use, the rubber cartridge needs to be installed on the glue supply block.

[0029] When the glue supply mechanism (such as a glue cartridge) needs to be replaced, the glue cartridge and the glue supply block are removed from the opposite direction of the connecting block, and then the glue cartridge to be replaced is removed from the glue supply block and replaced with a new one. At this time, the glue supply block is separated from the connecting block, and the connecting needle withdraws from the glue supply channel.

[0030] The lower end of the obliquely arranged communicating channel 4 is communicated with the glue inlet of the glue dispensing valve.

[0031] The nut 12 with external threads is connected to the inner wall of the flow channel hole 10 through threads.

[0035] The connecting needle 7 further comprises a connecting portion 72 threadedly connected to the inner wall of the mounting hole 6 and a tapered portion 73 capable of passing through the elastic gasket 5 , wherein the outer diameter of the tapered portion 73 gradually decreases in a direction away from the connecting portion 72 .

[0036] The working principle of the utility model is as follows:

[0037] When in use, the glue supply block needs to be installed on the glue supply cylinder so that the glue outlet of the glue cylinder is connected to the upper end of the vertical section of the glue supply flow channel on the glue supply block;

[0038] Similarly, the connecting block is installed on the dispensing valve so that the glue inlet of the dispensing valve is connected with the connecting flow channel on the connecting block;

[0039] When the rubber cartridge needs to be replaced, the old rubber cartridge and the rubber supply block are removed in the opposite direction of the connecting block. During this process, the connecting needle is pulled out from the rubber supply channel on the rubber supply block installed on the old rubber cartridge. At this time, the residual rubber in the rubber supply channel will not overflow under the action of the elastic gasket, and the sphere in the tapered through hole, which is no longer subjected to the pressure from the rubber liquid, is squeezed and contacted with the inner wall of the tapered through hole under the action of the spring to quickly cut off the connecting channel in the connecting block to avoid overflow of the rubber.

[0040] Then install the new rubber cartridge so that the connecting needle passes through the elastic gasket on the new rubber cartridge and is inserted into the rubber supply channel;

[0041] When the dispensing valve starts dispensing glue, the glue in the new glue cartridge flows toward the glue inlet of the dispensing valve. The ball in the tapered through hole moves under the glue pressure and squeezes the spring, thereby forming a glue outlet gap between the ball and the inner wall of the tapered through hole, thereby achieving communication between the glue outlet of the new glue cartridge and the glue inlet of the dispensing valve.

[0042] When the above-mentioned plug-in glue flow channel connecting component is adopted, it can realize the rapid connection and disassembly between the glue supply mechanism equipped with the glue supply block and the glue dispensing valve equipped with the connecting block, so as to facilitate the continuous glue supply to the glue dispensing valve by quickly replacing the glue supply mechanism. In the process of plugging and pulling out the replaced connecting needle, it is possible to quickly realize the rapid connection between the connecting flow channel on the connecting block and the glue supply flow channel in the replaced glue supply block, thereby realizing the rapid connection of the glue flow channel between the new glue supply mechanism and the glue dispensing valve. When the connecting block on the glue dispensing valve is separated from the glue supply block before replacement, it is possible to effectively avoid the overflow of residual glue in the glue supply flow channel and quickly cut off the connecting flow channel in the connecting block to avoid the overflow of glue. It is also possible to maintain the stability and consistency of the glue before and after replacement, thereby ensuring the consistency of glue dispensing quality.

[0043] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
