In the initial state, the two roll-carrying platforms 2 are respectively located at the two ends of the chassis 1, and the staff selects the corresponding control program according to the film roll to be carried, and the control system controls the linear traction structure 3 to pull the two roll-carrying platforms 2 to move synchronously and approach each other until the distance between the two roll-carrying platforms 2 is the set distance and stops moving; the manipulator transports the film roll to the film roll carrying mechanism, and the two end axes of the film roll are respectively supported by the top of the corresponding roll-carrying platform 2, and the film part of the film roll is located between the two roll-carrying platforms 2, so that it can adapt to the support of film rolls with different axial lengths, and has high applicability.

[0027] Specifically, the wheel structure includes two groups of driving wheel assemblies 6 symmetrically arranged on both sides of the chassis 1, each group of driving wheel assemblies 6 includes a housing 61, a driving motor 62 fixed on the chassis 1, a first wheel 64 and a second wheel 65 rotatably arranged on the chassis 1 in the front and rear directions, the rotating shafts of the first wheel 64 and the second wheel 65 extend in the left and right directions, so that the first wheel 64 and the second wheel 65 can only drive the film roll transporting trolley to move forward in the front and rear directions, a driving synchronous wheel 63 is sleeved on the main shaft of the driving motor 62, a first driven synchronous wheel 66 coaxial with the first wheel 64 is provided, and a second driven synchronous wheel 67 coaxial with the second wheel 65 is provided, and the first driven synchronous wheel 66, the second driven synchronous wheel 67 and the driving synchronous wheel 63 are connected by a synchronous belt 68. When the control system controls the driving motor 62 to rotate forward, the driving motor 62 drives the first driven synchronous wheel 66 and the second driven synchronous wheel 67 to move synchronously through the transmission of the driving synchronous wheel 63 and the synchronous belt 68, so that the first wheel 64 and the second wheel 65 move forward synchronously. On the contrary, when the control system controls the drive motor 62 to reverse, the drive motor 62 drives the first driven synchronous wheel 66 and the second driven synchronous wheel 67 to move synchronously through the transmission of the active synchronous wheel 63 and the synchronous belt 68, so that the first wheel 64 and the second wheel 65 move backward synchronously.

[0028] Furthermore, a tensioning wheel 69 for tensioning the synchronous belt 68 is provided on the chassis 1 to prevent the synchronous belt 68 from slipping and ensure that the synchronous belt 68 can be meshed and driven with the first driven synchronous wheel 66 and the second driven synchronous wheel 67 .

The top of the support block 23 is provided with a central V-shaped groove 24. The end shaft of the film roll can be positioned by sliding into the V-shaped groove 24 in the support block 23, without the need for an additional positioning mechanism to assist in positioning, and the film roll will not move even when the film roll is being transported.

[0030] Furthermore, a notch 221 is provided at the top of the vertical plate 22, and the bottom wall of the notch 221 protrudes upward to form a laterally extending guide bar 222.
