Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing machines, in particular to a glue dispensing machine which is convenient for replacing glue cartridges. Background Art

[0002] In industrial production, glue dispensing machines are essential automated equipment used to complete various glue dispensing and coating tasks.

[0003] During the use of the glue dispensing machine, when the glue in the glue cartridge is exhausted, the glue cartridge must be replaced in time. This process is often time-consuming and laborious because the operator needs to use a wrench to manually complete the disassembly, installation and adjustment steps, which undoubtedly reduces production efficiency. In addition, most of the glue dispensing machines on the market currently rely mainly on cylinders or gas to push the glue, but both have their advantages and disadvantages. The cylinder push method performs well in controlling thrust and speed, but it may be difficult to achieve uniform push when facing high-viscosity glue. Although the gas push method can achieve a relatively uniform push effect, it seems to be unable to control the force and speed, and the stability needs to be improved. Utility Model Content

The end of the extension plate 17 away from the fixed plate 1 is in the shape of two steps, and each step is fixedly connected to a laser displacement sensor 18 for detecting the dispensing thickness. The sensing ends of the two laser displacement sensors 18 are parallel to the dispensing heads on the two dispensing valves 3. A solenoid valve 19 fixedly connected to the bottom plate is provided below the support frame 15, and the cylinder A connecting frame 20 is fixed to the outer side of 1301, and air-controlled valves 21 are fixedly connected to both ends of the connecting frame 20, and a hand-operated valve 22 is provided between the two air-controlled valves 21.
