[0038] The mounting frame is also provided with a driving mechanism, which is used to drive the moving plate 4 to slide up and down in the filling cylinder 1 .

[0039] The mounting frame serves as the mounting base of the filling barrel 1 and is used to mount the filling barrel 1. The filling barrel 1 is a cylindrical structure with a closed bottom and an open top. The open top of the filling barrel 1 serves as a feed port for the adhesive and is used as a feed channel for replenishing the adhesive before filling. An output pipe 2 is fixedly connected to the bottom of the filling barrel 1. The output pipe 2 is communicated with the inside of the filling barrel 1. The connection point between the output pipe 2 and the filling barrel 1 is located at the bottom of the side wall of the filling barrel 1.

The side wall of the moving disk 4 abuts against the inner wall of the filling cylinder 1. The moving disk 4 slides with the inner wall of the filling cylinder 1. The moving disk 4 slides up and down inside the filling cylinder 1, thereby changing the discharge pressure of the adhesive. A driving mechanism is also provided on the mounting frame, and the driving mechanism is used to drive the moving disk 4 to slide up and down in the filling cylinder 1.

[0040] When in use, first open the cap of the plastic bottle 22, and place the plastic bottle 22 below the outlet end of the output tube 2, then open the valve 3, and then start the driving mechanism, which will drive the moving disk 4 to slide downward in the filling barrel 1. The moving disk 4 squeezes and pushes the adhesive during the downward sliding process. The adhesive is pushed by the moving disk 4 and is accelerated to be discharged toward the outlet end of the output tube 2 and finally enters the plastic bottle 22. The utility model drives the moving disk 4 to slide downward in the filling barrel 1 through the driving mechanism, thereby increasing the discharge speed of the adhesive from the outlet end of the output tube 2, thereby increasing the filling speed of the adhesive and improving the filling efficiency of the adhesive.

[0043] A limiting rod 7 is vertically penetrated through the movable plate 4, and the top end of the limiting rod 7 extends upward and is fixedly connected to the mounting frame.

[0044] The driving mechanism includes a screw rod 5 vertically penetrating the movable disk 4, the screw rod 5 is connected to the movable disk 4 by threaded cooperation, and the movable disk 4 can slide up and down along the inner wall of the filling cylinder 1 by rotating the screw rod 5. The driving mechanism also includes a motor 6 installed on the mounting frame, the motor 6 is located above the filling cylinder 1, the output end of the output shaft of the motor 6 extends vertically downward and is fixedly connected to the top of the screw rod 5 through a coupling 8, and the rotation of the output shaft of the motor 6 will drive the screw rod 5 to rotate. A limit rod 7 is also vertically penetrated on the movable disk 4, and the top of the limit rod 7 extends upward and is fixedly connected to the mounting frame. The limit rod 7 is used to limit the movable disk 4 from rotating with the screw rod 5 when the screw rod 5 drives the movable disk 4 to move.

[0045] Preferably, the motor 6 is a servo motor 6, and the rotation direction of the output shaft of the servo motor 6 can be changed by controlling the rotation direction of the screw rod 5, and the movement direction of the movable plate 4 can be further changed. The descending amplitude of the movable plate 4 can also be adjusted by controlling the number of rotations of the output shaft of the servo motor 6.

[0046] Specifically, in addition to the motor 6 and the screw 5, the driving mechanism may also include a hydraulic push mechanism such as a hydraulic push rod and an electric push mechanism such as an electric push rod.

[0047] When in use, the motor 6 is started, and the output shaft of the motor 6 rotates to drive the screw 5 to rotate. The rotation of the screw 5 drives the movable plate 4 to slide downward inside the filling cylinder 1. During the downward sliding process, the movable plate 4 squeezes and pushes the adhesive to be discharged out of the output tube 2.

[0048] In this embodiment: a limiting block 9 for limiting the position of the movable plate 4 is arranged at the bottom of the limiting rod 7 .

[0049] The limit block 9 is fixedly connected to the bottom of the limit rod 7. By using the limit block 9 as a limit structure of the movable plate 4, the position of the movable plate 4 can be limited, effectively preventing the movable plate 4 from slipping off the bottom of the limit rod 7.

[0054] In this embodiment, the end of the stirring blade 11 away from the mounting sleeve 10 abuts against the inner wall of the filling cylinder 1 .

[0055] During the rotation of the stirring blade 11 , the end thereof away from the mounting sleeve 10 can scrape the adhesive on the side wall of the filling barrel 1 , effectively reducing the possibility of the adhesive sticking to the side wall of the filling barrel 1 .

During the rotation of the stirring blade 11, the bottom surface of the stirring blade 11 and the end surface away from the mounting sleeve 10 can scrape the adhesive on the bottom surface of the filling cylinder 1 and the inner wall of the filling cylinder 1, and centrifugal force will be generated during the rotation of the stirring blade 11, which will cause the adhesive to be pushed outward, and the thrust will push the adhesive to move along the side of the stirring blade toward the side wall of the filling cylinder 1, thereby making it easier for the adhesive to enter the output pipe 2 and accelerate the discharge of the adhesive.
