[0035] Working principle and advantages of the present invention: When the milk powder can cover robot is in use, the working process is as follows:

[0036] like Figure 1 As shown, after the motor is started, the motor drives the gear disc 8 to Figure 1 When the toothed disc 8 drives the slide plate 13 to move downward from the upper end of the guide rod 9 through the push-pull rod 12, the toothed disc 8 is disengaged from the rack 19 and no longer in contact with it. At this time, the slide plate 13 moves downward and applies a thrust to the connection point of the second link 14 and the third link 15 through the connecting rod 10, so that the second link 14 and the third link 15 tend to be in a straight line, and then the second link 14 and the third link 15 push the pressing plate 24 to move downward along the direction of the slide groove 16, and the pressing plate 24 presses the cover body on the milk powder can onto the milk powder can, thereby realizing the cover-fastening operation of the milk powder can. In this process, since the toothed disc 8 is disengaged from the rack 19 and no longer in contact with it, when the pressing plate 24 presses the cover body, the conveyor belt 3 remains stationary, thereby ensuring the stability of the cover buckling and improving the success rate of the milk powder can buckling.

[0037] like Figure 2 and Figure 3As shown, when the pressure plate 24 moves downward, the shaft frame 25 drives the twisted rod 26 to move downward synchronously. At this time, the twisted rod 26 is twisted under the action of the inner wall of the I-shaped through hole on the fixed block 17 and the spiral surface of the twisted rod 26, so that the twisted rod 26 drives each paddle 27 to rotate, and then the inclined surface of each paddle 27 is in contact with each ball head 33 and slides relatively. When the inclined surface is in contact with the ball head 33, the inclined surface exerts downward pressure on the ball head 33, so that the strip through hole 32 at the end of the connecting rod 4 31 moves upward, so that the pin rod 2 30 drives the sliding rod 29 and the hammer head 34 to move upward in the corresponding slideway 35, and at the same time the ball head 33 is pressed against the corresponding spring When the spring 1 36 is compressed, the spring 1 36 obtains a restoring force. When the local inclined surface is away from the ball head 33 and does not contact, the ball head 33 moves up under the restoring force of the spring 1 36, and drives the pin 2 30 to move down through the connecting rod 4 31 and the strip through hole 32, so that the pin 2 30 drives the hammer head 34 to move down through the sliding rod 29 and vibrates and strikes the cover body, so that the cover body is fully fastened to the milk powder can by the striking of the hammer head 34 while the pressure plate 24 presses down on the cover body, thereby improving the sealing performance of the cover body, ensuring the connection stability of the milk powder can cover, avoiding air from entering the milk powder can due to loose fastening of the cover body, and improving the hygiene and safety of food in the milk powder can.

[0038] When the toothed disc 8 drives the slide plate 13 to move upward from the lower end of the guide rod 9 through the push-pull rod 12, the toothed disc 8 is meshed with the rack 19. At this time, while the slide plate 13 moves upward, a pulling force is applied to the connection point of the second link 14 and the third link 15 through the connecting rod 10, so that the second link 14 and the third link 15 change from a straight line state to a sharp angle state and the angle gradually decreases, thereby causing the second link 14 and the third link 15 to drive the pressure plate 24 to move along the direction of the slide groove 16 away from the milk powder can. At the same time, the toothed disc 8 drives the piston plate 21 to move rightward in the pump barrel 20 through the rack 19, so that the piston plate 21 compresses the air in the pump barrel 20. The conducting direction of the one-way valve 1 22 points to the inside of the pump barrel 20, and the conducting direction of the one-way valve 23 points to the pump wheel 5, so that the air in the pump barrel 20 enters the pump wheel 5 through the air pipe 6, and then the airflow drives the impeller shaft to rotate and drives the corresponding roller 4 to rotate synchronously, so that the roller 4 drives the conveyor belt 3 to run, so that the conveyor belt 3 moves the buckled milk powder can away from the bottom of the pressure plate 24, and moves the next milk powder can to be buckled to the bottom of the pressure plate 24, so that the conveyor belt 3 is driven to intermittently transport the milk powder cans with covers during the process of the pressure plate 24 buckling the cover body, which greatly improves the degree of automation, saves time and effort, and improves work efficiency.

[0039] As described above, the piston plate 21 compresses the spring 2 38 while moving rightward in the pump barrel 20, so that the spring 2 38 obtains a restoring force. When the toothed disc 8 is out of contact with the rack 19, the piston plate 21 and the rack 19 move leftward under the restoring force of the spring 2 38 and apply a suction force to the pump barrel 20, so that the suction force draws air into the pump barrel 20 through the one-way valve 1 22, so that the conveyor belt 3 can be driven by compressed air to transport the milk powder cans next time.

[0040] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
