The receiving box is divided into a first area and a second area by a partition. A placement shaft passing through the receiving box is provided in the first area. The placement shaft is supported and mounted on the partition by a support shaft seat. A rotary power device is fixedly mounted on the partition below the placement shaft and is drively connected to the placement shaft. A glue bucket is provided in the second area and fixedly mounted on a glue bucket plate. A first linear power device for pressing down glue is provided above the glue bucket and fixedly mounted on a linear power support plate. The glue bucket plate and the linear power support plate... All support plates are installed inside the receiving box and located in the second area. One end of the support arm is fixed to the receiving box, and the other end of the support arm is fixedly installed with a glue applicator. The glue applicator includes a hinge, and a second linear power device is fixedly installed on the surface of the hinge. The second linear power device is connected to a connecting plate, and a glue dispensing clamping mechanism is fixedly installed on the connecting plate. The glue dispensing clamping mechanism clamps the glue dispensing tube and moves vertically with the connecting plate. A glue dispensing power device is fixedly installed on the upper part of the glue dispensing tube, and a glue inlet tube is fixedly installed on one side of the glue dispensing tube through a glue inlet switch. The glue inlet tube is connected to the bottom of the glue tank. The receiving box is also equipped with... The device includes an anti-drying mechanism to prevent clogging of the dispensing tube opening. The anti-drying mechanism comprises a first linear module and a second linear module. The first linear module is fixedly mounted on the receiving box along the support arm direction via a first fixing plate. A first slider is slidably mounted on the first linear module, and a second fixing plate is fixedly mounted on the first slider. A second linear module is fixedly mounted on the second fixing plate, and a second slider slides vertically on the second linear module. A clamping plate is fixedly connected to the second slider, and the clamping plate holds an anti-drying container to facilitate solvent immersion into the dispensing tube opening. The anti-drying mechanism also includes a solvent storage tank. The solvent storage tank is fixed to the second fixed plate. A drive piston is movably installed inside the solvent storage tank. A drive rod is connected to the bottom of the drive piston. The drive rod is fixedly connected to the second slider. A liquid outlet is provided at the upper end of the solvent storage tank. The liquid outlet is connected to the bottom of the anti-drying tank through a solvent outlet pipe. The first linear module is provided with a standby station and a working station. The first slider moves back and forth between the standby station and the working station. When the first slider slides to the working station, the anti-drying tank corresponds to the dispensing pipe. When the second linear module rises to the highest point, the dispensing pipe is inside the anti-drying tank.

2. The filter bag bottom coating machine as described in claim 1, characterized in that: The second linear power device includes a drive cylinder, and the extension guide rod of the drive cylinder is connected to a connecting plate. When the drive cylinder descends to the lowest point, the dispensing tube is close to the placement shaft. When the drive cylinder rises to the highest point, a gap for an anti-drying device is left between the dispensing tube and the placement shaft.

3. The filter bag bottom coating machine as described in claim 2, characterized in that: The drive cylinder includes a cylinder body, a piston is installed inside the cylinder body, the upper end of the extended guide rod is connected to the piston, a limit rod is fixedly connected to the upper end of the piston, and the upper end of the limit rod passes through the cylinder body and is fitted with a limit block.

4. The filter bag bottom coating machine as described in claim 3, characterized in that: The limiting block is a limiting nut, which is threaded onto the limiting rod.

5. A filter bag bottom coating machine as described in claim 4, characterized in that: The transmission connection includes a driving gear, a driven gear, and a chain. The driving gear is connected to the output end of the rotary power device. One end of the driven gear is connected to the placement shaft. The driving gear and the driven gear are driven by a chain. The other end of the placement shaft is provided with a filter bag fixing wheel.

6. The filter bag bottom coating machine as described in claim 5, characterized in that: The glue dispensing clamping mechanism includes an optical axis clamping seat, on which a glue tube optical axis is provided, and on which a glue dispensing tube clamping seat is provided, and the glue dispensing tube is clamped on the glue dispensing tube. The glue dispensing tube has a glue channel inside, and the outlet of the glue dispensing tube has a strip-shaped structure.

7. A filter bag bottom coating machine as described in claim 6, characterized in that: The first linear power device includes a glue-pressing cylinder, and the telescopic rod of the glue-pressing cylinder is provided with a barrel pressure plate that matches the glue barrel, and the barrel pressure plate extends into the glue barrel.
