Pushing mechanisms are installed in the plurality of slots 7. The pushing mechanism includes a piston 8, a plurality of springs 9 and a transmission component. The piston 8 is sealed and slidably sleeved in the card slot 7. The plurality of springs 9 are all arranged in the card slot 7, and the two ends are respectively fixedly connected to the inner end of the piston 8 and the inner wall of the card slot 7. An annular groove 10 is provided inside the rotor 4. A ring body 11 is rotatably sleeved in the middle of the rotor 4. A convex block 12 is fixedly installed on one side of the ring body 11 close to the liquid inlet chamber 5. Multiple groups of transmission components are alternately in contact with the convex block 12. The piston 8 moves back and forth under the drive of the transmission component and the spring 9. Two connecting rods 13 are symmetrically and radially mounted on the front side of the housing 3. The inner ends of the two connecting rods 13 are fixedly connected to the front side of the ring body 11, and the outer ends of the two connecting rods 13 are connected to the adjustment mechanism. An overflow groove 14 is formed on the inner wall of the upper end of the shell 3 , and the overflow groove 14 is communicated with the liquid outlet cavity 6 .

[0015] The linkage components include a main shaft 15, a coupling 2 and two connecting frames 16. The two connecting frames 16 are horizontally radially arranged and symmetrically placed. The two ends of the connecting frame 16 are respectively fixedly connected to the back of the shell 3 and the front end of the motor 1. A guide tube 17 is horizontally fixedly installed at the port of the liquid inlet chamber 5. The guide tube 17 is connected to the glue storage device for supplying glue. A discharge pipe 18 is horizontally fixedly installed at the port of the liquid outlet chamber 6. The discharge pipe 18 is used to connect with the glue end to output the glue. The main shaft 15 is horizontally radially rotatably sleeved in the shell 3 and passes through the front and rear sides of the shell 3. The rotor 4 is fixedly sleeved with the main shaft 15. The output end of the motor 1 is fixedly connected to the tail end of the main shaft 15 through the coupling 2.

[0016] The transmission components include a support plate 19, a gear 20, a pin 21, a first rack 22, a push rod 23, a second rack 24 and a ball 25. The two ends of the support plate 19 are fixedly connected to the inner walls of the slot 7 on both sides, the pin 21 is fixedly installed on the support plate 19, the gear 20 is rotatably sleeved on the pin 21, the end of the first rack 22 is fixedly installed on the inner end of the piston 8, the push rod 23 is slidably sleeved in the rotor 4, and the two ends are respectively located in the slot 7 and the annular groove 10, the second rack 24 is fixedly installed on the end of the push rod 23 located in the slot 7, the first rack 22 and the second rack 24 are both meshed with the gear 20 and located on both sides, and the ball 25 is rollingly embedded in the end of the push rod 23 located in the annular groove 10.

[0017] The protrusion 12 is in a step shape, and adjacent steps are smoothly connected. The plurality of balls 25 are in rolling contact with the protrusion 12 alternately.

[0018] The step lifts on the bump 12 are different in size. The lift is smaller when it is close to the center of the rotor 4 and larger when it is far from the center of the rotor 4, thereby adjusting the moving distance of the push rod 23. The height difference between adjacent steps is smaller than the radius of the ball 25.

[0019] When the device is used to transport the glue liquid, the motor 1 is started, and the motor 1 drives the main shaft 15 to rotate through the coupling 2, and the main shaft 15 drives the rotor 4 to rotate counterclockwise to push the glue liquid.

[0020] As the rotor 4 rotates, the pushing mechanism rotates back to the area of ​​the liquid inlet chamber 5. At this time, the ball 25 rolls in contact with the protrusion 12 and enters a lift, so that the push rod 23 is pushed, and the push rod 23 drives the second rack 24. The second rack 24 drives the gear 20 to rotate. The gear 20 causes the first rack 22 to drive the piston 8 to retract into the slot 7 to form a cavity, and at the same time compresses the spring 9. The glue enters the cavity formed at the outer end of the slot 7 and rotates with the rotor 4.

[0021] When the card slot 7 with the glue liquid leaves the area of ​​the liquid inlet chamber 5 and rotates to the upper area of ​​the shell 3, the outer end of the card slot 7 is connected to the overflow groove 14, and at the same time the push rod 23 leaves the protrusion 12, the thrust is released, the spring 9 returns to its original length, releases the elastic force, pushes the piston 8 out and resets it, the piston 8 pushes the glue liquid out, the glue liquid enters the liquid outlet chamber 6 through the overflow groove 14, and is finally discharged through the discharge pipe 18 to realize the transportation of the glue liquid.

[0022] With the cooperation of the pushing mechanism, the rotor 4 rotates, so that the card slot 7 completes the liquid absorption, and then the glue liquid can be released in advance through the overflow groove 14 without waiting to move to the area of ​​the liquid outlet cavity 6, thereby shortening the glue liquid transportation journey and improving efficiency.

[0023] When the glue liquid is discharged, the spring 9 releases its elastic force, which has a pressurized pushing effect on the glue liquid, further increasing the conveying speed of the glue liquid, thereby improving efficiency.

[0024] The adjusting mechanism includes an impeller 26, two tension springs 27 and a retaining ring 28. Two slide grooves 29 are symmetrically opened on the front side of the main shaft 15. The impeller 26 is slidably mounted on the main shaft 15 and is located in the slide groove 29. The upper and lower sides of the back side of the retaining ring 28 are respectively fixedly connected to the front ends of the two connecting rods 13. The front end of the retaining ring 28 is rotatably sleeved with the rear end of the impeller 26. The two tension springs 27 are both horizontally arranged and symmetrical up and down. The two ends of the tension spring 27 are respectively fixedly connected to the side of the retaining ring 28 and the housing 3 that are close to each other.

[0025] During the rotation of the main shaft 15 , the rotor 4 is driven to rotate. By adjusting the speed of the motor 1 , the speed of the rotor 4 is adjusted, thereby adjusting the output speed of the glue and the output amount.

[0026] The main shaft 15 rotates, and at the same time drives the impeller 26 to rotate, generating airflow. When the main shaft 15 rotates at a faster speed, the impeller 26 rotates at a high speed, generating a larger aerodynamic force, stretching the tension spring 27, and the impeller 26 moves toward the front end of the main shaft 15, driving the retaining ring 28 to move. The retaining ring 28 drives the ring body 11 to move through the two connecting rods 13, and the ring body 11 drives the protrusion 12 to move, so that the area with a large lifting stroke of the protrusion 12 is opposite to the ball 25, so that the push rod 23 obtains a larger stroke, and then the displacement of the piston 8 is longer, so that when the slot 7 is in the liquid inlet chamber 5, the effective cavity formed is larger, and more glue can be transported.

[0027] When the main shaft 15 rotates at a slow speed, the impeller 26 rotates at a low speed, and the aerodynamic force is small. Under the tension of the tension spring 27, the impeller 26 moves to the rear end of the main shaft 15, so that the area with a small lifting stroke of the protrusion 12 is opposite to the ball 25, so that the push rod 23 obtains a smaller stroke, and then the displacement of the piston 8 is shorter, and the effective cavity formed by the slot 7 is smaller, which can transport less glue.

[0028] With the cooperation of the adjustment mechanism, the size of the effective cavity formed by the slot 7 can be adjusted. At high speed, a large cavity is formed, the conveying time is short, and the carrying capacity is large. At low speed, a small cavity is formed, the conveying time is long, and the carrying capacity is small, thereby achieving efficient adjustment of the size of the glue delivery volume.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
