The inner wall of the middle part of the through hole 61 is provided as a slope surface matched with the first sphere 9, so that the first sphere 9 can be pressed and contacted with the slope surface inclined inwardly in the direction away from the glue supply nut 7 under the action of the spring 8 in the extrusion state. A second mounting hole 15 connected with the connecting flow channel 4 is provided on the side end surface of one end of the connecting block 2 facing the glue supply block 1 with the connecting flow channel 4, and one end of a horizontally extending glue inlet connector 16 is embedded and installed in the second mounting hole 15;

[0022] When installation is required, the glue inlet connector is aligned with the glue supply connector and moved toward the glue supply connector. As the distance of the glue inlet connector entering the glue supply connector becomes longer and longer, the first sphere is pressed into contact with the glue inlet connector and pushed away from the through hole, so that a gap appears between the first sphere and the through hole.

[0023] The end surface of the glue inlet connector 16 located at one end in the second mounting hole 15 is provided with a flow channel hole 10, and a transition flow channel 161 with an inner diameter smaller than that of the flow channel hole 10 is provided between the other end of the glue inlet connector 16 and the flow channel hole 10, and the transition flow channel 161 is connected to the flow channel hole 10 through a conical through hole 11, and a glue inlet nut 12 with a second central through hole 121 is installed at the end of the flow channel hole 10 opposite to the transition flow channel 161, and the end surface of the glue inlet nut 12 is connected to a conical through hole 11. A second spring 14 in a squeezed state is horizontally arranged between the second spheres 13, so that the second sphere 13 having a diameter larger than the inner diameter of the transition channel 161 can be squeezed and contacted with the inner wall of the tapered through hole 11. When the end of the glue inlet connector 16 away from the second mounting hole 15 penetrates into the through hole 61 and is squeezed and contacted with the first sphere 9 in the through hole 61, a gap is formed between the first sphere 9 and the slope surface of the inner wall of the through hole 61, so that one end of the transition channel 161 is connected with the glue supply channel 3 on the glue supply block 1.

[0024] The glue enters the transition flow channel of the glue inlet connector from the through hole, and the first sphere 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 the glue from entering the flow channel hole, avoiding glue overflow during installation.

[0029] The second mounting hole 15 is communicated with the upper end of the communication channel 4 .

[0030] Embodiment 2: A detachable connecting mechanism for a glue flow channel, comprising a glue supply block 1 installed on a glue supply mechanism and a connecting block 2 installed on a glue dispensing valve, wherein the glue supply block 1 having a glue supply flow channel 3 therein is provided with a first mounting hole 5 on its side surface facing the connecting block 2, the glue supply flow channel 3 whose one end is connected to the glue outlet of the glue supply mechanism is connected to the first mounting hole 5 at the other end, a horizontally extending glue supply connector 6 is embedded and installed in the first mounting hole 5 at one end, the glue supply connector 6 is provided with a through hole 61 which passes through in a horizontal direction, a glue supply nut 7 having a central through hole 71 is installed at one end of the through hole 61 close to the glue supply flow channel 3, and a One end of the spring 8 horizontally arranged in the through hole 61 contacts the end surface of the glue supply nut 7, and the other end of the spring 8 is provided with a first sphere 9. The inner wall of the middle part of the through hole 61 is provided as a slope surface matched with the first sphere 9, so that the first sphere 9 can be pressed and contacted with the slope surface inclined inwardly in the direction away from the glue supply nut 7 under the action of the spring 8 in the extrusion state. A second mounting hole 15 connected with the connecting flow channel 4 is provided on the side end surface of one end of the connecting block 2 facing the glue supply block 1 with the connecting flow channel 4, and one end of a horizontally extending glue inlet connector 16 is embedded and installed in the second mounting hole 15;

[0031] When in use, the rubber cartridge needs to be installed on the rubber supply block;

[0032] When the rubber cartridge needs to be replaced, the rubber supply block is removed from the opposite direction of the connecting block, and then the rubber cartridge to be replaced is removed from the rubber supply block and replaced with a new rubber cartridge. At this time, the rubber supply block is separated from the connecting block, and the connecting needle exits the rubber supply channel;

[0033] The end surface of the glue inlet connector 16 located at one end in the second mounting hole 15 is provided with a flow channel hole 10, and a transition flow channel 161 with an inner diameter smaller than that of the flow channel hole 10 is provided between the other end of the glue inlet connector 16 and the flow channel hole 10, and the transition flow channel 161 is connected to the flow channel hole 10 through a conical through hole 11, and a glue inlet nut 12 with a second central through hole 121 is installed at the end of the flow channel hole 10 opposite to the transition flow channel 161, and the end surface of the glue inlet nut 12 is connected to a conical through hole 11. A second spring 14 in a squeezed state is horizontally arranged between the second spheres 13, so that the second sphere 13 having a diameter larger than the inner diameter of the transition channel 161 can be squeezed and contacted with the inner wall of the tapered through hole 11. When the end of the glue inlet connector 16 away from the second mounting hole 15 penetrates into the through hole 61 and is squeezed and contacted with the first sphere 9 in the through hole 61, a gap is formed between the first sphere 9 and the slope surface of the inner wall of the through hole 61, so that one end of the transition channel 161 is connected with the glue supply channel 3 on the glue supply block 1.

[0034] In the above process, the connecting block moves away from the glue supply block and drives the glue inlet connecting piece away from the glue supply connecting piece. The first sphere in the glue supply connecting piece approaches the through hole under the extrusion of the first spring and is squeezed into contact with the through hole, blocking the outward passage of the glue liquid. The glue can be stopped to avoid glue overflow when replacing the glue cylinder, thereby reducing glue waste.

[0035] The lower end of the obliquely arranged communicating channel 4 is communicated with the glue inlet of the glue dispensing valve.

[0036] The second sphere 13 is a ceramic sphere.

[0037] The outer surface of the glue supply connector 6 and the inner wall of the first mounting hole 5 , and the outer surface of the glue inlet connector 16 and the inner wall of the second mounting hole 15 are both connected by threads.

[0038] The outer surface of the glue supply nut 7 and the inner wall of the through hole 61 on the glue supply connector 6, and the outer surface of the glue inlet nut 12 and the inner wall of the flow channel hole 10 are both connected by threads.

[0039] The working principle of the utility model is as follows:

[0040] 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 with the glue supply channel on the glue supply block;

[0041] 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;

[0042] When the rubber cartridge needs to be replaced, the old rubber cartridge and the rubber supply block are removed in the opposite direction to the connecting block, the rubber supply block is separated from the connecting block, and the rubber feed connector is separated from the first sphere;

[0043] In this process, the first sphere is pressed and contacted with the slope surface of the inner wall of the through hole under the action of the first spring to quickly cut off the entire glue supply flow channel; at the same time, the second sphere is also pressed and contacted with the inner wall of the tapered through hole under the action of the second spring to quickly cut off the connecting flow channel, thereby preventing the glue from overflowing;

[0044] Then, a new rubber cartridge is installed, the rubber supply block is connected to the connection block, the rubber feed connector is inserted into the through hole on the rubber feed connector and is pressed and contacted with the first ball, and the first ball moves toward the first spring under the push of the rubber feed connector and presses the first spring, thereby forming a gap between the first ball and the slope surface of the inner wall of the through hole to connect the transition flow channel and the rubber supply flow channel on the rubber supply block; at the same time, the second ball in the tapered through hole is always pressed and contacted with the inner wall of the tapered through hole under the squeezing action of the second spring, thereby preventing the glue from entering the connecting flow channel before dispensing, and avoiding the glue overflow during installation;

[0045] When the dispensing valve starts dispensing glue, the glue with a certain pressure in the new glue supply cylinder flows toward the glue inlet of the dispensing valve. During this process, the second sphere moves under the glue pressure and squeezes the second spring, thereby forming a glue outlet gap between the second sphere and the inner wall of the tapered through hole, thereby achieving communication between the glue outlet of the new glue cylinder and the glue inlet of the dispensing valve.

[0046] When the above-mentioned detachable connecting mechanism of the glue flow channel is adopted, it can realize the quick connection and disassembly between the glue supply mechanism equipped with the glue supply block and the dispensing valve equipped with the connecting block, so as to continuously supply glue to the dispensing valve by quickly replacing the glue supply mechanism. In the process of replacement, it can realize the quick 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 quick connection of the glue flow channel between the new glue supply mechanism and the dispensing valve. When the connecting block on the dispensing valve is separated from the glue supply block before replacement, the connecting flow channel on the connecting block and the glue supply flow channel in the glue supply block can be quickly cut off at the same time, thereby avoiding the waste caused by glue overflow and damage to the dispensing product, and maintaining the stability and consistency of the glue before and after replacement, thereby ensuring the consistency of dispensing quality.

[0047] 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.
