[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 2The utility model provides an embodiment: a paint bucket production line capping device, including a conveyor 1, the conveyor 1 is connected to the paint canning production line, so that the filled paint and paint bucket can be directly transported to the inside of the device for capping. A positioning assembly is provided at the bottom of the conveyor 1, and the positioning assembly can effectively position and fix the paint bucket to ensure stability and precision during capping. Two mounting seats 2 are fixedly connected to the top of the conveyor 1, and a hydraulic rod 3 is installed on the top of the mounting seat 2. The output end of the hydraulic rod 3 is fixedly connected to a top plate 4. The mounting seat 2, the hydraulic rod 3 and the top plate 4 form the main support structure of the capping device, so that the capping device can move down and contact the paint bucket for capping, and separate from the capped paint bucket when moving up, so as to facilitate the capping of subsequent paint buckets one by one.

[0030] Reference Figure 1 , Figure 3 and Figure 4 , an electric cylinder 5 is fixedly connected to the middle of the top plate 4, a connecting block 6 is fixedly connected to the output end of the electric cylinder 5, a fixing frame 7 is fixedly connected to both sides of the bottom of the top plate 4, a ring frame 8 is fixedly connected between the two fixing frames 7, and the ring frame 8 is fixed by the two fixing frames 7. The capping equipment can achieve stable size adjustment during the capping process, and then adapt to the capping processing of different types of paint buckets. A plurality of movable arms 9 are slidably connected inside the ring frame 8, a connecting rod 18 is provided at one end of the movable arm 9, and a bracket 10 is fixedly connected to the other end of the movable arm 9. A capping jaw 11 is rotatably connected inside the bracket 10, and a fixing rod 12 is fixedly connected to the top of the capping jaw 11, and a movable rod 13 is provided between the fixing rod 12 and the connecting block 6. Start the hydraulic rod 3 to drive the top plate 4 downward, so that the capping jaw 11 drops and contacts the top of the paint bucket. At the same time, the bucket cover that was magnetically fixed to the bottom of the magnetic pressure plate 19 in advance also contacts the top of the paint bucket synchronously. At this time, the electric cylinder 5 is started to drive the connecting block 6 to move upward, so that the upward movement of the connecting block 6 will pull the movable rod 13 and the fixed rod 12 to expand and flip accordingly. The flipping of the fixed rod 12 drives the sealing jaw 11 to flip toward the direction of the annular frame 8. During the process, the sealing jaw 11 will squeeze the edge of the metal bucket cover, so that the edge of the bucket cover is deformed equidistantly and embedded in the outside of the metal ring on the top of the paint bucket, thereby completing the sealing operation.

[0031] Reference Figure 2-Figure 4, the top of the annular frame 8 is fixedly connected with a spherical frame 14, the inner top wall of the spherical frame 14 is fixedly connected with a motor 15, the output end of the motor 15 is fixedly connected with a turntable 16, and the top edge of the turntable 16 is fixedly connected with multiple eccentric shafts 17. Start the motor 15 to drive the turntable 16 to rotate, and the eccentric shaft 17 is driven to move in a circle through the rotation of the turntable 16, and then the eccentric shaft 17 pulls the corresponding movable arm 9 through the connecting rod 18 to move inside the annular frame 8, so that the circular ring structure composed of multiple movable arms 9 can adjust the diameter length and the size of the barrel cover. One end of the connecting rod 18 is rotatably connected to the outer periphery of the eccentric shaft 17, and the other end of the connecting rod 18 is hinged to the end of the movable arm 9 away from the bracket 10. Through the cooperation of the connecting rod 18 and the eccentric shaft 17, the force of the rotation of the turntable 16 can be converted into a linear pulling force on the movable arm 9, and then all the movable arms 9 are driven to move together synchronously, ensuring that the structure for the capping after the size adjustment still maintains a ring structure. One side of the movable rod 13 is slidably connected to the inside of the fixed rod 12, and the other side of the movable rod 13 is hinged to the outer periphery of the connecting block 6. When the movable arm 9 moves to drive the bracket 10 and the capping jaw 11 to adjust the size of the cap, the capping jaw 11 will pull the fixed rod 12 to slowly move a distance from the outside of the movable rod 13 to ensure that the adjusted capping device can still be connected to the connecting block 6. A magnetic pressure plate 19 is fixedly connected to the bottom of the turntable 16. The magnetic pressure plate 19 is located at the bottom of the annular frame 8. Through the cooperation of the magnetic pressure plate 19 and the mechanical arm, the barrel cover can be magnetically fixed on the magnetic pressure plate 19, which is convenient for subsequent capping processing.

[0032] Reference Figure 1-Figure 2The positioning assembly includes two fixed blocks 20, the top of the fixed block 20 is fixedly connected to the bottom of the conveyor 1, a motor 21 is fixedly connected to the middle of one of the fixed blocks 20, a bidirectional threaded rod 22 is rotatably connected between the two fixed blocks 20, and threaded sleeves 23 are threadedly connected to both sides of the outer periphery of the bidirectional threaded rod 22, a V-shaped frame 24 is slidably connected inside the mounting seat 2, and a connecting arm 25 is arranged between the V-shaped frame 24 and the threaded sleeve 23. When the conveyor 1 transports the filled paint bucket to the bottom of the top plate 4, the motor 21 starts to drive the bidirectional threaded rod 22 to rotate, and then drives the two threaded sleeves 23 to move toward each other, and the threaded sleeve 23 pulls the connecting arm 25 to drive the two V-shaped frames 24 to move, so that the two V-shaped frames 24 slide inside the mounting seat 2 and approach each other. Until the inner side structures of the two V-shaped frames 24 are respectively against the outer side of the paint bucket, the paint bucket can be moved toward the center of the two V-shaped frames 24 through the structural characteristics of the V-shaped frame 24, thereby completing the positioning and clamping of the paint bucket. One end of the connecting arm 25 is fixedly connected to the end of the V-shaped frame 24 away from the electric cylinder 5, and the other end of the connecting arm 25 is fixedly connected to the bottom of the threaded sleeve 23, so that the threaded sleeve 23 can drive the V-shaped frame 24 with the help of the connecting arm 25, and then drive the V-shaped frame 24 to position and clamp the paint bucket. One end of the bidirectional threaded rod 22 is fixedly connected to the output end of the second motor 21, so that the second motor 21 can directly drive the bidirectional threaded rod 22 to rotate, and position and clamp the paint bucket.

[0033] Working principle: When it is necessary to cap the bucket lids of different sizes of paint buckets, it is only necessary to start the motor 15 to drive the turntable 16 to rotate, and the rotation of the turntable 16 drives the eccentric shaft 17 to move in a circle, and then the eccentric shaft 17 pulls the corresponding movable arm 9 to move inside the ring frame 8 through the connecting rod 18, so that the circular ring structure composed of multiple movable arms 9 can adjust the diameter length to match the size of the bucket lid. At the same time, when the movable arm 9 drives the bracket 10 and the capping clamp 11 to adjust the size of the cap, the capping clamp 11 will pull the fixed rod 12 to slowly move a distance from the outside of the movable rod 13 to ensure that the adjusted capping device can still be connected to the connecting block 6.

[0034] During the capping process, when the conveyor 1 conveys the paint bucket to between the two mounting seats 2, the conveyor 1 stops running, and the motor 21 starts to drive the bidirectional threaded rod 22 to rotate, and then drives the two threaded sleeves 23 to move toward each other, and the threaded sleeves 23 pull the connecting arm 25 to drive the two V-shaped frames 24 to move, so that the two V-shaped frames 24 slide inside the mounting seat 2 and move toward each other. Until the inner side structures of the two V-shaped frames 24 are respectively against the outer side of the paint bucket, the paint bucket can be moved toward the center of the two V-shaped frames 24 through the structural characteristics of the V-shaped frames 24, thereby completing the positioning and clamping of the paint bucket, ensuring that the paint bucket is located below the capping clamp 11.

[0035] Then start the hydraulic rod 3 to drive the top plate 4 downward, so that the capping jaw 11 descends and contacts the top of the paint bucket. At the same time, the bucket cover that was magnetically fixed to the bottom of the magnetic pressure plate 19 in advance also contacts the top of the paint bucket synchronously. At this time, start the electric cylinder 5 to drive the connecting block 6 to move upward, so that the upward movement of the connecting block 6 will pull the movable rod 13 and the fixed rod 12 to expand and flip accordingly, and the capping jaw 11 will flip toward the direction of the annular frame 8 through the flipping of the fixed rod 12. During the process, the capping jaw 11 will squeeze the edge of the metal bucket cover, so that the edge of the bucket cover will be deformed equidistantly and fit into the outside of the metal ring at the top of the paint bucket, and then complete the capping operation. After that, you only need to drive the connecting block 6 downward, so that the movable rod 13 and the fixed rod 12 will shrink and flip accordingly, so that the fixed rod 12 drives the capping jaw 11 to reset and rotate, and release from the outside of the paint bucket.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
