The mounting frame has a U-shaped structure, and a mixing box is fixed inside the mounting frame. An air extraction pipe is fixed on the mixing box, and a valve is installed on the air extraction pipe. A first sealing seat slides on the cover plate. The first sealing seat is located below the air extraction pipe, and a screw is threadedly connected to the first sealing seat. One end of the screw rotates on the cover plate.

[0006] Furthermore, the cover plate has a stepped structure, with the outer wall of the lower half of the cover plate contacting the inner wall of the mixing chamber, and the bottom end face of the upper half of the cover plate contacting the top end face of the mixing chamber.

[0007] Furthermore, a second sealing seat is welded to the inner wall of the mixing box. The second sealing seat has a U-shaped structure, and the upper end face of the second sealing seat is in contact with the bottom end face of the cover plate.

[0008] Furthermore, a mixing assembly is installed on the mixing box. The mixing assembly consists of a mixing plate, a first gear, and a motor.

The motor is electrically connected to an external control switch and an external power supply. The output shaft of the motor is fixed on the rotating shaft of the mixing plate.

[0009] Furthermore, an adjustment assembly is installed on the rotating shaft. The adjustment assembly consists of a second gear, a sliding rod, a gear rack, and a second hydraulic cylinder. The second gear is welded to the rotating shaft. Two sliding rods slide on the equipment frame. The inner sides of the two sliding rods are welded to the gear rack. The gear rack meshes with the second gear. A second hydraulic cylinder is fixed on the equipment frame. The extended end of the second hydraulic cylinder is fixed to the gear rack.

The mounting frame 102 has a U-shaped structure, and a mixing box 2 is fixed inside the mounting frame 102. An air extraction pipe 202 is fixed on the mixing box 2, and a valve 203 is installed on the air extraction pipe 202; a first sealing seat 204 slides on the cover plate 201, and the first sealing seat 204 is located below the air extraction pipe 202. A screw 205 is threadedly connected to the first sealing seat 204, and one end of the screw 205 rotates on the cover plate 201. During vacuuming, an external vacuuming device is connected to the air extraction pipe 202 and then vacuuming is performed. After vacuuming is completed, the screw 205 is rotated, and under the thread drive of the screw 205, the first sealing seat 204 moves upward to complete the sealing of the air extraction pipe 202, thereby improving the sealing effect of the air extraction pipe 202.

[0025] The cover plate 201 has a stepped structure. The outer wall of the lower half of the cover plate 201 contacts the inner wall of the mixing box 2, and the bottom surface of the upper half of the cover plate 201 contacts the top surface of the mixing box 2. The stepped structure of the cover plate 201 can improve the sealing performance between the cover plate 201 and the mixing box 2.

[0026] The mixing chamber 2 has a second sealing seat 206 welded on its inner wall. The second sealing seat 206 has a U-shaped structure. The upper end face of the second sealing seat 206 is in contact with the bottom end face of the cover plate 201. The second sealing seat 206 can improve the sealing performance between the cover plate 201 and the mixing chamber 2.

[0027] The mixing box 2 is equipped with a mixing component 3, which consists of a mixing plate 301, a first gear 302, and a motor 303. There are two rotating mixing plates 301 on the mixing box 2. A first gear 302 is welded on the rotating shaft of each mixing plate 301. The two first gears 302 mesh. The motor 303 is fixed on the mixing box 2. The motor 303 is electrically connected to the external control switch and external power supply. The output shaft of the motor 303 is fixed on the rotating shaft of the mixing plate 301. When mixing, the motor 303 can be started. Under the drive of the motor 303, the two mixing plates 301 rotate to achieve kneading.

[0028] The rotating shaft 101 is equipped with an adjustment assembly 5, which consists of a second gear 501, a sliding rod 502, a gear rack 503, and a second hydraulic cylinder 504. The second gear 501 is welded to the rotating shaft 101. Two sliding rods 502 slide on the equipment frame 1, and the inner sides of the two sliding rods 502 are welded to the gear rack 503. The gear rack 503 meshes with the second gear 501. The second hydraulic cylinder 504 is fixed on the equipment frame 1, and the extended end of the second hydraulic cylinder 504 is fixed to the gear rack 503. When unloading, the second hydraulic cylinder 504 is driven to extend, and the second hydraulic cylinder 504 drives the gear rack 503 to move. Under the meshing transmission of the gear rack 503 and the second gear 501, the mixing box 2 can be rotated, thereby realizing the pouring of the adhesive liquid in the mixing box 2.

[0029] Example 2: Based on Example 1, two first hydraulic cylinders 4 are symmetrically fixed on the equipment frame 1. Both first hydraulic cylinders 4 are driven by an external hydraulic pump. The extended ends of both first hydraulic cylinders 4 are fixed on the cover plate 201. When the cover plate 201 is opened, the two first hydraulic cylinders 4 are driven to extend. The two first hydraulic cylinders 4 drive the cover plate 201 to move upward, which improves the convenience of opening the cover plate 201.

[0030] Working principle: In use, the first hydraulic cylinder 4 drives the cover plate 201 to move upward, opening the mixing box 2 and allowing the sealant material to be added into the box; then, the first hydraulic cylinder 4 is controlled to retract, causing the cover plate 201 to close on the mixing box 2, with the stepped cover plate tightly fitting against the second sealing seat 206, completing the initial seal; if vacuum kneading is required, the external vacuum equipment is connected to the suction pipe 202, and the valve 203 is opened to perform the vacuum operation; after the vacuum is completed, the valve 203 is closed, and the screw 205 is rotated to drive the first sealing seat 204 to move upward, blocking the suction pipe 202 to achieve a secondary seal and ensure the vacuum environment inside the box; The motor 303 is started, which drives one of the mixing plates 301 to rotate. Through the transmission of two meshing first gears 302, the other mixing plate 301 rotates synchronously in the opposite direction. The mixing plate 301 is used to fully mix and knead the raw materials. After kneading, the second hydraulic cylinder 504 is driven to extend, which drives the toothed rack 503 to move. Through the meshing transmission of the toothed rack 503 and the second gear 501, the rotating shaft 101 drives the mounting frame 102 and the mixing box 2 to rotate to a suitable angle, so as to realize the rapid unloading of raw materials. After unloading, the second hydraulic cylinder 504 is controlled to retract, so that the mixing box 2 is reset and ready for the next operation.
