[0017] 2. The pallet wrapping machine uses a limiting component. The mounting seat drives the slide plate to slide on the surface of the slide bar. At the same time, the mounting seat drives the second T-block to slide in the second T-slot until the slide plate squeezes the spring, causing the slide plate to drive the long block to move out of the long slot, making it convenient to take the plug plate out of the slot later, so that the wrapping film roller can be replaced.

[0019] 4. The pallet wrapping machine places the material on the placing turntable through the clamping mechanism, and then drives the rotating shaft to rotate when the motor is started, and the rotating shaft drives the gear to rotate. Since the gear and the annular gear ring are meshed and connected, the gear can rotate in a circle around the annular gear ring. When the gear moves, the annular slide plate can slide in the annular slide groove. At the same time, when the rotating plate and the limit ring are hinged, when the rotating shaft drives the rotating plate to rotate, the limit ring can be driven to move, and the limit ring can drive the connecting plate, and the connecting plate drives the first T-block to slide in the first T-slot, so that the four limit rings can limit the edge of the material, which is convenient for the later rotation of the placing turntable to drive the material to rotate, and can prevent the material from being thrown out of the placing turntable to a certain extent.

Embodiment 3

[0030] See also Figure 1-9 , and on the basis of the first embodiment, the clamping mechanism 2 further comprises a first T-slot 202, the first T-slot 202 is opened around the top of the placing turntable 1, the first T-slot 202 is slidably connected with a first T-block 201 inside, the top of the first T-block 201 is fixedly connected with a connecting plate 28, the top of the connecting plate 28 is fixedly connected with a limiting ring 29, the top of the placing turntable 1 is fixedly connected with an annular gear ring 203, the outer side of the placing turntable 1 is opened with an annular slide groove 21, and the inside of the annular slide groove 21 is slidably connected with An annular skateboard 22, a motor 23 is fixedly connected to the top of the annular skateboard 22, a rotating shaft 24 is fixedly connected to the top of the motor 23, a gear 25 is fixedly connected to the surface of the rotating shaft 24, a rotating plate 27 is fixedly connected to the upper surface of the rotating shaft 24, the other side of the rotating plate 27 is hinged to the outer side of the limiting ring 29, and a rotating ring 26 is hinged to the side of the rotating plate 27 away from the limiting ring 29.

When the film on the wrapping film roller 3 is used up and the wrapping film roller 3 needs to be replaced regularly, the bolt 42 is first threadedly removed, and the telescopic rod 46 is retracted and taken out of the insertion slot 41 again, and the rotating seat 44 is rotated on the surface of the rotating rod 43, so that the telescopic rod 46 can be driven away from the insertion slot 41, so that the wrapping film roller 3 can be replaced later. When the mounting seat 523 is toggled, the slide plate 529 is driven to slide on the surface of the slide rod 528. At the same time, the mounting seat 523 drives the second T-block 524 to slide in the second T-slot 525 until the slide plate 529 squeezes the spring 526, so that the slide plate 529 drives the long block 522 to move out of the long slot 521. At this time, the insert plate 519 can be directly pulled out of the slot 516, and the telescopic plate 518 can be driven to shrink. At this time, it is convenient to directly take out the wrapping film roller 3 from the square slot 511, and the wrapping film roller 3 can be replaced, so that the new wrapping film roller 3 can be installed conveniently to avoid being affected when the material is wrapped.
