[0029] An electric telescopic rod 3 is fixedly installed at the bottom of the storage box 1, and a main board 4 is fixedly installed on the top of the telescopic end of the electric telescopic rod 3. The main board 4 is sealingly and slidably connected in the storage box 1, and multiple groups of irradiation lamps 41 are fixedly installed on the top of the main board 4. A mounting head 51 is fixedly installed on the top of the irradiation lamp 41. The hot melt glue stick can be tightly inserted in the mounting head 51, and an elastic telescopic tube 5 is arranged on the top of the mounting head 51. A guide sleeve 52 is arranged on the top of the elastic telescopic tube 5, and a guide hole 53 is opened on the outer side of the guide sleeve 52. Multiple groups of cross braces 11 are arranged inside the storage box 1, and a guide column 12 is arranged on the top of the cross brace 11. The guide column 12 passes through the main board 4 and the guide hole 53, and an anti-slip block is arranged on the top of the guide column 12. The pressing sleeve 23 can be tightly inserted in the guide sleeve 52, and the inner diameter of the pressing sleeve 23 is larger than the outer diameter of the hot melt glue stick.

[0030] When storing, push the sliding box cover 2 to make the discharge hole 21 correspond to the guide sleeve 52, and then control the electric telescopic rod 3 to operate, the electric telescopic rod 3 drives the main board 4 to rise, and the main board 4 drives the installation head 51 to rise. At this time, the guide sleeve 52 cannot rise due to the restriction of the guide column 12, and the installation head 51 squeezes the elastic telescopic tube 5, and the installation head 51 is close to the discharge hole 21, and then the hot melt glue stick is tightly inserted into the installation head 51, which is convenient for installation. After the installation is completed, control the electric telescopic rod 3 to descend, the electric telescopic rod 3 drives the main board 4 to descend, the main board 4 drives the installation head 51 to descend, and the installation head 51 drives the hot melt glue stick to descend, and the elastic telescopic tube 5 is opened under its own elastic force. When the main board 4 is completely lowered, push the sliding box cover 2 to slide. The pressing sleeve 23 corresponds to the guide sleeve 52, and then the pressing sleeve 23 is controlled to descend. The pressing sleeve 23 is first tightly inserted into the guide sleeve 52, and then the guide sleeve 52 is driven to descend synchronously.

[0031] When taking materials, first control the pressing sleeve 23 to rise, and the pressing sleeve 23 first drives the guide sleeve 52 to rise. When the guide sleeve 52 rises to the top of the guide column 12, the anti-slip block limits the rise of the guide sleeve 52, and the pressing sleeve 23 breaks away from the guide sleeve 52, pushing the sliding box cover 2 so that the discharge hole 21 corresponds to the guide sleeve 52, and then control the electric telescopic rod 3 to operate, the electric telescopic rod 3 drives the main board 4 to rise, and the main board 4 drives the installation head 51 to rise. At this time, the guide sleeve 52 cannot rise under the restriction of the guide column 12, and the installation head 51 squeezes the elastic telescopic tube 5, and the installation head 51 drives the hot melt glue stick to be ejected through the discharge hole 21.

When the main board 4 is completely lowered, the sliding box cover 2 is pushed to slide, so that the pressing sleeve 23 corresponds to the guide sleeve 52, and then the driving motor is controlled to be energized, the driving motor drives the lifting screw 28 to rotate, the lifting screw 28 drives the lifting rod 29 to rise, the lifting rod 29 relaxes the transmission rope 26, and the top spring 24 pushes the pressing sleeve 23 to descend. The pressing sleeve 23 is first tightly inserted in the guide sleeve 52, and then drives the guide sleeve 52 to descend synchronously, and the guide sleeve 52 squeezes the elastic telescopic tube 5. Because the transmission rope 26 is completely relaxed, the pressing sleeve 23 can be sleeved on hot melt glue sticks of different lengths under the action of the top spring 24, which is suitable for hot melt glue sticks of different lengths and is simple to control;
