[0008] Further technical scheme, one end of the sliding plate away from the diameter adjusting assembly is arc-shaped.

[0009] Further technical scheme, one end of the sliding plate away from the diameter adjusting assembly is fixedly provided with a friction layer.

[0010] Further technical scheme, the inner top of placing frame is also fixedly connected with the matching barrel, and the inner wall of matching barrel is slidably connected with the middle plate.

[0011] In a further technical solution, the lower end of the abutment plate is lower than the lower end of the container.

[0012] A further technical solution includes a first motor, a fixed shaft, a receiving plate, an arc-shaped groove, a mating groove, and a fixed rod. The lower end of the intermediate plate is fixedly connected to the first motor, and the drive end of the first motor is fixedly connected to the fixed shaft. The lower end of the fixed shaft is rotatably connected to the bottom end of the accommodating barrel. The receiving plate is fixedly sleeved on the outer wall of the fixed shaft. The receiving plate has multiple evenly distributed arc-shaped grooves, and each arc-shaped groove corresponds to a sliding plate. Each sliding plate has a mating groove, and a fixed rod is fixedly installed on the inner wall of the mating groove, with the fixed rod abutting against the inner wall of the arc-shaped groove.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. The electric telescopic rod extends, causing the intermediate plate to descend. The intermediate plate then lowers the receiving bucket, allowing the abutment plate and friction layer to extend into the can. The first motor then rotates, driving the fixed shaft to rotate. The fixed shaft then rotates the receiving plate, which in turn rotates the arc-shaped groove around the axis of the fixed shaft. The arc-shaped groove, via the fixed rod, causes the sliding plates to slide along the groove, moving multiple sliding plates away from each other. The sliding plates then cause the abutment plate to contact the inner wall of the can, thus securing the can on the conveying device. The second motor then rotates the cooperating bucket, which in turn rotates the can. An industrial camera captures images of the can's surface and transmits them to the backend for pattern inspection, effectively avoiding the influence of subjective experience and fatigue on the inspection results, resulting in high inspection efficiency.

[0015] 2. By using linen or seersucker to make the friction layer, the friction between the sliding plate and the inner wall of the can is increased, effectively preventing the can from sliding during rotation and improving stability, thereby avoiding affecting the pattern captured by the industrial camera on the surface of the can.
