[0019] In actual use, the extruded hot-melt adhesive pellets are put into the tank body 1 through the feed port, and the hot-melt adhesive pellets are received by the tank body 1; then the drive motor is started, and the cam 3 is driven to rotate by the output shaft of the drive motor. During the rotation, the cam 3 drives the bulk plate 2 to rotate back and forth, so as to shock the hot-melt adhesive pellets and fall into the return channel along the length direction of the bulk plate 2 with the Xinao hot-melt adhesive pellets; under the action of their own gravity, the hot-melt adhesive pellets roll along the return channel, and while rolling, the hot-melt adhesive pellets are thermally dried by the hot air component.

[0021] It is worth mentioning that when the bulk plate 2 contacts the outer wall surface of the cam 3, the bulk plate 2 is in a state of being tilted downward from the horizontal plane, ensuring that the hot melt adhesive particles roll along the length direction of the bulk plate 2 under the action of their own gravity.

[0022] Specifically, the drying tank also includes: an installation shaft 21, the installation shaft 21 is arranged on the tank body 1, and the bulk plate 2 is rotatably arranged on the installation shaft 21; the side of the bulk plate 2 close to the installation shaft 21 abuts against the inner wall surface of the tank body 1 to prevent the hot-melt adhesive particles from passing through the bulk plate 2 and directly falling into the return channel; the side of the bulk plate 2 away from the installation shaft 21 is at a fixed distance from the inner wall surface of the tank body 1 to guide the hot-melt adhesive particles to fall into the return channel.

The hot air can be distributed to several air supply pipes 52 through one distribution tray to ensure the hot air delivery efficiency; the hot air can pass through the air supply holes 53 to deliver the hot air between the feeding plates 4 at different heights, thereby improving the drying efficiency of the hot melt glue particles.

[0025] It is worth mentioning that a resistance wire can be arranged in the heating component 55 for heating.

[0026] Specifically, the air supply plate 51 is disposed at the bottom of the tank body 1 , one end of the air supply pipe 52 is connected to the air supply plate 51 , and the other end is sealed to increase the flow rate of hot air outputted from the air supply hole 53 .

[0027] Preferably, the angle α between the feeding plate 4 and the horizontal plane is 20°.

[0028] Specifically, the drying tank also includes: a discharge port, which is opened on the side wall of the tank body 1; a collecting plate 6, which is arranged below the feeding plate 4, with one end on one side of the discharge port and the other end extending upward at an angle to the horizontal plane for receiving hot melt adhesive particles; a gate 11, which is used to block the discharge port.
