[0027] See appendix Figure 1-4 As shown, the can lid 5 includes a frustum lid 501 that is rotatably snapped onto the upper end of the can cylinder 2, a second rubber ring 502 that is bonded and fixed to the lower end of the inner side of the frustum lid 501, a second pin 503 that is inserted into the through hole on the edge of the frustum lid 501, and a third rubber ring 504 that is bonded and fixed to the upper end of the inner side of the frustum lid 501. The second rubber ring 502 has three annular grooves evenly distributed on its inner side, and the third rubber ring 504 has four annular grooves evenly distributed on its inner side.

[0028] The protrusion at the upper end of the can 2 is inserted into the limiting sleeve at the lower end of the frustum cover 501, and the lower end of the second pin 503 is inserted into the groove on the protruding surface at the upper end of the can 2.

[0029] Specifically, the frustum cover 501 is a sealing cover at the upper end of the tank 2. Its upper end is connected to the stirring mechanism 6 by a rotating lock, and its lower end is locked to the tank 2, forming a closed mixing space. The lower end limiting sleeve rotates and engages with the upper protrusion of the tank 2, and is locked by the second pin 503. The upper protrusion rotates and engages with the motor outer frame 601 of the stirring mechanism 6, and is locked by the third pin 602. The second rubber ring 502 is bonded to the lower inner side of the frustum cover 501. The three annular grooves on the inner side enhance the sealing of the connection between the tank 2 and the cover 5, preventing the glue from overflowing or evaporating. The second pin 503 is inserted into the edge through hole of the frustum cover 501, and its lower end engages with the groove of the upper protrusion of the tank 2, locking the connection between the cover 5 and the tank 2. The third rubber ring 504 is bonded to the upper inner side of the frustum cover 501. The four annular grooves on the inner side enhance the sealing of the connection between the cover 5 and the stirring mechanism 6, preventing dust or debris from entering the tank.

[0030] See appendix Figure 1-3 As shown, the stirring mechanism 6 includes a motor outer frame 601 that is rotatably fastened to the upper end of the frustum cover 501, a third pin rod 602 inserted into the through hole on the upper surface of the motor outer frame 601, a stirring motor 603 welded to the inner side of the motor outer frame 601, and a stirring rod 604 welded to the lower end of the rotating shaft of the stirring motor 603. The lower end of the third pin rod 602 is inserted into the through hole protruding on the upper end of the frustum cover 501.

[0031] Specifically, the motor outer frame 601 is the outer shell of the stirring mechanism 6, protecting the internal stirring motor 603. It is connected to the frustum cover 501 of the tank cover 5 via a rotary lock to ensure stable stirring. The lower protrusion is engaged with the upper limit sleeve of the frustum cover 501 and locked by the third pin 602. The third pin 602 is inserted into the through hole on the upper surface of the motor outer frame 601 and the lower end is inserted into the through hole of the protrusion on the upper end of the frustum cover 501 to lock the connection between the stirring mechanism 6 and the tank cover 5. The stirring motor 603 provides stirring power, driving the rotating shaft to rotate the stirring rod 604, so that the glue raw materials are fully mixed in the tank to ensure the uniformity of the glue solution. The stirring rod 604 is welded to the lower end of the rotating shaft of the stirring motor 603 and extends into the tank 2. By rotating and stirring the glue solution, it breaks up the agglomeration of raw material particles and promotes the fusion of components.

[0032] The operation process of this utility model is as follows: During equipment assembly, the tank bottom 1 is placed in a suitable operating position. The electric butterfly valve 7 is installed at the lower end of the funnel 101 of the tank bottom 1 by bolts. The protrusion at the lower end of the tank cylinder 2 is aligned with the limiting sleeve at the upper end of the funnel 101. The tank cylinder 2 is rotated so that the protrusion is engaged with the limiting sleeve. Then, the first pin 103 is inserted, and the lower end of the first pin 103 is engaged in the groove on the surface of the protrusion at the lower end of the tank cylinder 2 to lock the connection between the tank bottom 1 and the tank cylinder 2. The movable collar 301 of the heating outer ring 3 is placed above the outer limiting ring of the tank cylinder 2 to ensure that the heating spiral tube 302 is tightly fitted with the outer wall of the tank cylinder 2. Align the limiting sleeve at the lower end of the frustum cover 501 of the can lid 5 with the protrusion at the upper end of the can cylinder 2, rotate the frustum cover 501 to lock it in place, insert the second pin 503, and insert the lower end of the second pin 503 into the groove on the surface of the protrusion at the upper end of the can cylinder 2 to lock the connection between the can lid 5 and the can cylinder 2. Align the protrusion at the lower end of the motor outer frame 601 of the stirring mechanism 6 with the limiting sleeve at the upper end of the frustum cover 501, rotate the motor outer frame 601 to lock it in place, insert the third pin 602, and insert the lower end of the third pin 602 into the through hole of the protrusion at the upper end of the frustum cover 501 to lock the connection between the stirring mechanism 6 and the can lid 5.

[0034] During temperature control and stirring, the power and temperature of the heating spiral tube 302 are set on the control box 4 according to the mixing process requirements of the plywood adhesive. The heating system is started to heat the raw materials in the tank 2. The temperature inside the tank is monitored in real time to ensure that the temperature is stable within a suitable range. The stirring motor 603 is started. The stirring motor 603 drives the rotating shaft to rotate the stirring rod 604, so that the plywood adhesive raw materials are fully mixed in the tank. During the stirring process, the stirring speed and time can be adjusted through the control box 4 as needed to ensure the uniformity of the adhesive solution.

[0035] During discharge, after mixing is completed, the heating system and stirring motor 603 are turned off through control box 4, and then the electric butterfly valve 7 is opened by electric drive to control the discharge of the mixing tank. The discharge amount is precisely adjusted according to actual needs to complete the quantitative use of the splicing adhesive.

[0036] During cleaning and maintenance, after discharging, close the electric butterfly valve 7, disassemble each component, and clean the tank bottom 1, tank cylinder 2, tank cover 5, stirring mechanism 6 and electric butterfly valve 7 in the reverse order of assembly.
