[0022] When installation is required, the support base is placed close to the connecting block, the first magnet on the support base is attracted and fixed to the second magnet on the fixed block, and then the pin is inserted into the positioning hole to fix the support base and the fixed block. At this time, the transition flow channel and the glue supply flow channel are aligned and connected, which can realize the rapid disassembly and fixed installation of the rubber cartridge, and the stable installation of the rubber cartridge, avoiding the shaking of the rubber cartridge during the dispensing process, thereby improving the quality and efficiency of dispensing.

[0023] The above-mentioned glue supply block 1 is provided with a first mounting hole 5 on the side surface facing the connecting block 2, and the lower end of the glue supply channel 3 whose upper end is connected with the glue outlet 171 of the glue supply cylinder 17 is connected with the first mounting hole 5, and one end of a horizontally extending glue supply connector 6 is embedded and installed in the first mounting hole 5, and a through hole 61 penetrating in the horizontal direction is provided on the glue supply connector 6, and a glue supply nut 7 with a central through hole 71 is installed at one end of the through hole 61 close to the glue supply channel 3, and one end of a spring 8 horizontally arranged in the through hole 61 contacts the end surface of the glue supply nut 7, and the spring A sphere 9 is disposed at the other end of the through hole 61, and the inner wall of the middle part of the through hole 61 is disposed as a slope surface matched with the sphere 9, so that the 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, and a second mounting hole 15 connected with the connecting flow channel 4 is provided on the side surface of the connecting block 2 facing the glue supply block 1, and one end of a horizontally extending glue inlet connector 16 is embedded and installed in the second mounting hole 15, and a transition flow channel 161 is provided between the other end of the glue inlet connector 16 and the connecting flow channel 4;

[0036] When replacement is required, the support seat on which the rubber supply cylinder is installed is removed from the opposite direction of the connecting block, and then the rubber cylinder to be replaced is removed from the rubber supply block and replaced with a new one. At this time, the rubber supply block is separated from the connecting block.

[0037] The first magnet 131 and the second magnet 132 are respectively embedded in the receiving grooves 123 provided on the supporting seat 121 and the fixing block 122 .

[0045] The working principle of the utility model is as follows:

[0046] 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;

[0047] 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;

[0048] Afterwards, the new glue supply cylinder is moved toward the valve body until the second magnet installed on the valve body and the first magnet installed on the glue supply cylinder are fixed by suction under the restriction of the pin and the pin positioning hole, thereby realizing a quick connection between the valve body and the glue supply cylinder with good connection stability, and improving the assembly accuracy between the two and the position accuracy of the glue supply connector before and after the glue supply cylinder is replaced, thereby improving the stability of the glue supply from the glue supply cylinder to the valve body and the glue dispensing of the valve body;

[0049] The glue supply block is connected to the connecting block, and the glue inlet connecting piece penetrates into the through hole on the glue supply connecting piece and is squeezed into contact with the ball. The ball moves toward the spring direction under the push of the glue inlet 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 inlet block on the valve body.

[0050] When the above-mentioned dispensing unit with a detachable glue cartridge is used, it is convenient to disassemble and replace the glue supply cartridge connected to the valve body, and at the same time, a quick connection between the valve body and the glue supply cartridge is achieved with good connection stability, and the assembly accuracy between the two and the position accuracy of the glue supply connector before and after the glue supply cartridge is replaced can be improved, thereby improving the stability of the glue supply from the glue supply cartridge to the valve body and the dispensing of the valve body;

[0051] Furthermore, in the process of replacing the glue supply cylinder, the glue inlet block on the valve body can be quickly connected with the glue flow channel inside 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 products.
