The drive gear 47 and the driven gear 48 mesh with each other.

[0022] Specifically, the first hydraulic push rod 42 is operated to extend the cover plate 45 into the rim of the plastic bucket, and the drive motor 46 is started to rotate the drive gear 47. The drive gear 47 transmits power to the driven gear 48, and the driven gear 48 rotates the rotating shaft 44 and the cover plate 45, thus driving the plastic bucket to rotate.

[0023] In this embodiment, the cleaning mechanism 3 includes a mounting frame 31, a second hydraulic push rod 32, an arc plate 33, a water spray pipe 34, an air outlet pipe 35, and a sponge roller 36. The mounting frame 31 is fixedly installed on the right side of the front of the U-shaped plate 41.

[0024] Specifically, before labeling the plastic bucket, connect the water spray pipe 34 to the alcohol delivery pipe and the air outlet pipe 35 to the hot air delivery pipe. Operate the second hydraulic push rod 32 to bring the sponge roller 36 to the plastic bucket body. As the bucket body rotates, the water spray pipe 34 sprays alcohol onto the bucket body, the sponge roller 36 wipes the bucket body, and the air outlet pipe 35 blows out hot air to dry the bucket body. In this way, impurities attached to the plastic bucket body can be cleaned before labeling.

[0025] In this embodiment, the clamping mechanism 2 includes a cylinder 21, an arc-shaped clamping plate 22, and a proximity switch 23. Three cylinders 21 are fixedly installed on both the left and right sides of the conveyor belt 1. An arc-shaped clamping plate 22 is fixedly installed at the output end of the cylinder 21. A proximity switch 23 is fixedly installed on both the left and right sides of the conveyor belt 1 in front of the cylinder 21.

[0026] Specifically, when the proximity switch 23 senses that a bucket is passing by, it will operate the cylinders 21 on both sides to move the arc-shaped clamping plates 22 relative to each other to perform the clamping operation of the plastic bucket.

[0027] In this embodiment, the labeling mechanism 6 includes a winding roller 61, a limiting roller 62, a vertical plate 63, a third hydraulic push rod 64, and a labeling roller 65. The winding roller 61 is rotatably mounted on the top front end and the top right end of the worktable 5. Two limiting rollers 62 are rotatably mounted on the top right end of the worktable 5. The vertical plate 63 is fixedly mounted on the top of the worktable 5 and to the left of the limiting rollers 62. The third hydraulic push rod 64 is embedded on the right side of the vertical plate 63. The labeling roller 65 is fixedly mounted on the output end of the third hydraulic push rod 64. A drive motor is fixedly mounted inside the worktable 5. The output end of the drive motor passes through the worktable 5 and is fixedly connected to the winding roller 61.

[0028] Specifically, the label roll is installed on the right-side winding roller 61, one end of the label roll is passed through two limiting rollers 62 and fixed on the front winding roller 61, and the two drive motors are started at the same time to loosen the label roll with the right-side winding roller 61 while the front winding roller 61 rewinds the applied label. The third hydraulic push rod 64 is operated to push the labeling roller 65 out to fit tightly against the barrel body, thus performing the labeling operation of the plastic barrel.

[0029] In this embodiment, the detection mechanism 7 includes a housing 71, a camera 72, a fourth hydraulic push rod 73, and an arc-shaped push plate 74. The housing 71 is fixedly installed on the back of the workbench 5. The camera 72 is fixedly installed on the front side of the inner top wall of the housing 71. The fourth hydraulic push rod 73 is fixedly installed on the rear side of the inner wall of the housing 71. The arc-shaped push plate 74 is fixedly installed at the output end of the fourth hydraulic push rod 73.

[0030] It should be noted that the proximity switch 23, the first hydraulic push rod 42, the second hydraulic push rod 32, the cylinder 21, the third hydraulic push rod 64, the camera 72, the drive motor, the drive motor 46, and the fourth hydraulic push rod 73 are all electrically connected to an external controller.

[0031] Specifically, camera 72 can capture the labeling status of the bucket and upload the labeling video information to the controller in real time. The controller analyzes whether the label on the bucket is properly affixed through its internal integrated program. When the controller determines that the label on the bucket is not properly affixed, the controller operates the fourth hydraulic push rod 73 to push the plastic bucket without a proper label onto the defective product table 9 with the arc-shaped push plate 74. In this way, the automatic screening of defective products is achieved.

[0032] The working principle of the above embodiment is:

[0033] (1) Place the plastic bucket to be labeled on the conveyor belt 1, connect the water spray pipe 34 to the alcohol conveying pipe, connect the air outlet pipe 35 to the hot air conveying pipe, install the label roll on the right winding roller 61, pass one end of the label roll through the two limit rollers 62 in sequence and fix it on the front winding roller 61. As the conveyor belt is conveyed, when the front proximity switch 23 senses the information that a bucket has passed, it will operate the cylinders 21 on both sides to move the arc clamping plate 22 relative to each other, so that the plastic bucket moves to the center position of the conveyor belt 1 for subsequent labeling operations. As the conveyor belt 1 moves, the plastic bucket continues to move forward.

[0034] (2) When the proximity switch 23 in the middle senses that a bucket is passing by, it will operate the cylinders 21 on both sides to move the arc-shaped clamping plate 22 relative to each other until the arc-shaped clamping plate 22 fits against the bucket body.

[0035] (3) Operate the first hydraulic push rod 42 to extend the cover plate 45 into the rim of the plastic bucket, start the drive motor 46 to rotate the drive gear 47, the drive gear 47 transmits power to the driven gear 48, the driven gear 48 rotates the rotating shaft 44 and the cover plate 45, driving the plastic bucket to rotate.

[0036] (4) Operate the second hydraulic push rod 32 to bring the sponge roller 36 to fit the plastic barrel body. As the barrel body rotates, the water spray pipe 34 sprays alcohol onto the barrel body, the sponge roller 36 wipes the barrel body, and the air outlet pipe 35 blows out hot air to dry the barrel body and clean the impurities attached to the barrel body.

[0037] (5) By operating the third hydraulic push rod 64, the labeling roller 65 can be pushed out to fit tightly against the barrel body, and the labeling operation of the plastic barrel can be carried out.

[0038] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations.
