Referring to fig. 1, the present invention provides a film roll lifting structure, which includes a bottom plate 1, vertical plates 2 symmetrically disposed on the bottom plate 1, and a roll carrying platform 3 disposed between the two vertical plates 2, wherein two sides of the roll carrying platform 3 are slidably connected to the corresponding vertical plates 2, the roll carrying platform 3 is driven by a driving mechanism 4 to move up and down, and the top of the roll carrying platform 3 is used for carrying one end of a film roll.

In practical application, the two film roll lifting structures provided by the utility model are symmetrically arranged on the film conveying trolley, and the finished film roll products can be horizontally placed on the cache frame. The film roll lifting structure and the film conveying trolley are matched with each other, loading, unloading and carrying supporting work of film rolls can be completed, the film conveying trolley firstly moves to the position right below the film rolls during carrying, and the driving mechanisms 4 on the two film roll lifting structures drive the corresponding film roll carrying platforms 3 to synchronously move upwards, so that the two film roll carrying platforms 3 lift the film rolls together, the film rolls are separated from the buffer storage frame, and the film conveying trolley carries the film rolls to a storage workshop; the film conveying trolley conveys the film rolls to the upper part of the vacant storage rack, and then the corresponding film roll carrying platforms 3 are driven by the driving mechanisms 4 on the two film roll lifting structures to synchronously move downwards, so that the two film roll carrying platforms 3 unload the film rolls to the storage rack together.

Specifically, the driving mechanism 4 comprises a door-shaped frame 41 arranged below the roll-loading table 3, a screw nut 42 fixedly arranged on the roll-loading table 3, a driving motor 43 fixed on the bottom plate 1, and a speed reducer 44 in transmission connection with the driving motor 43, wherein the screw nut 42 is sleeved on a vertically extending screw rod 45, the lower end of the screw rod 45 is rotationally connected with the door-shaped frame 41, and the output end of the speed reducer 44 is in driving connection with the lower end of the screw rod 45 through a coupler. When the driving motor 43 drives the screw rod 45 to rotate forwards, the screw rod nut 42 and the film carrying and winding table 3 move vertically upwards, so that the height of the film carrying and winding table 3 is changed, and the film carrying and winding table 3 is further enabled to lift the film roll. Conversely, when the driving motor 43 drives the screw rod 45 to rotate reversely, the screw rod nut 42 and the roll loading platform 3 move vertically downward, so that the height of the roll loading platform 3 is reduced, and the unloading of the film roll is completed. The screw rod 45 transmission structure has the advantages of high transmission precision and stable movement, ensures the synchronism and the accuracy of the lifting structure of the two film rolls for lifting one end of the film roll, and reduces the height difference of the two ends of the film roll.

Further, the roll table 3 comprises a top plate 31 and two extension arms 32 arranged at the bottom of the top plate 31, and the door-shaped frame 41 is arranged between the two extension arms 32, so that the structure is compact and the mutual interference is avoided. The top of roof 31 is provided with V type groove 33 placed in the middle, and the location just can be realized to V type groove 33 in the end shaft slip roof 31 that the membrane was rolled up, need not additionally to set up positioning mechanism assistance-localization real-time, even the membrane is rolled up and also can not take place to remove at fortune material in-process membrane.

Specifically, the middle part of the top plate 31 is provided with an avoidance hole for the lead screw 45 to vertically enter, and the lead screw nut 42 is installed at the bottom of the top plate 31. When the film roll lifting structure is in a non-lifting state, the screw rod nut 42 is close to the top of the door-shaped frame 41, and the screw rod 45 extends into the avoiding hole but does not penetrate through the top of the top plate 31, so that the whole structure is more compact and reasonable.
