A fixing table 15 is fixed in the middle of the top beam 14 and is used for fixedly connecting with a lifting device, such as the bottom end of a piston rod of a lifting cylinder. The left-hand rail mechanism 21 and the right-hand rail mechanism 22 are fixedly connected to the bottom surface of the horizontal bottom plate 11, and the left-hand driving mechanism 41 and the right-hand driving mechanism 42 are arranged in the frame 1.
The left clamping and grabbing plate 51 and the right clamping and grabbing plate 52 need to be clamped at the middle section of the film roll and coincide with the gravity center of the film roll; in order to avoid the film roll from being shaken or tilted forward or backward when the film roll is lifted, the left gripping and grabbing plate 51 and the right gripping and grabbing plate 52 need to have a certain length of not less than 40% of the length of the film roll, but the left gripping and grabbing plate 51 and the right gripping and grabbing plate 52 are not too long, and generally do not exceed 50% of the length of the film roll. The axial length of the film roll is about 900-1000mm, and the lengths of the left gripping and grabbing plates 51 and the right gripping and grabbing plates 52 are about 360-500mm, so that although only one of the left sliding mechanism 31 and the right sliding mechanism 32 is theoretically required, in practical application and selection, two to three left sliding mechanisms 31 and right sliding mechanisms 32 are generally provided in combination with the lengths and the stabilities of the left gripping and grabbing plates 51 and the right gripping and grabbing plates 52, and the left sliding mechanisms 31 and the right sliding mechanisms 32 are alternately arranged along the front-rear length direction of the frame 1 for better balance.

Further, the left-hand rail mechanism 21/right-hand rail mechanism 22 includes two rail plates 2-2 spaced apart from each other in front and rear, and the rail plates 2-2 are structurally represented as arch bridges, the bottoms of which are fixedly attached to the bottom surface of the bottom plate 11 of the frame 1. Each left-direction track mechanism 21/right-direction track mechanism 22 is provided with two arc-shaped tracks 2-1, the arch bridge shape of the track plates 2-2 is matched with the arc-shaped tracks 2-1, and the opposite side surfaces of the two track plates 2-2 are respectively provided with the arc-shaped tracks 2-1.

The track plate 2-2 is provided with a plurality of through holes 2-21 which are spaced apart and communicated with the arc track 2-1 along the extending direction of the arc track 2-1, and are used for exposing the position of the rolling elements 3-22 on the arc track 2-1, the size of the through holes 2-21 is matched with the shape and the size of the rolling elements 3-22, and the position of the left clamping grabbing plate 51/the right clamping grabbing plate 52 can be well judged by the position of the rolling elements 3-22.

When the left clamping grabbing plate 51 and the right clamping grabbing plate 52 move along the circumferential direction of the film roll, the left clamping grabbing plate 51 and the right clamping grabbing plate 52 are unfolded immediately, and the lengths of the left clamping grabbing plate 51 and the right clamping grabbing plate 52 can be matched to cover the lower half part of the film roll basically, so that the clamping range of the left clamping grabbing plate 51 and the right clamping grabbing plate 52 for the film roll is enlarged, and the film roll is clamped more stably and reliably.
In addition, at least one hollowed block 5-3 is formed on each of the left clamping and grabbing plate 51 and the right clamping and grabbing plate 52, so that on one hand, the weight of the left clamping and grabbing plate 51 and the right clamping and grabbing plate 52 can be reduced, and the load weight can be reduced; on the other hand, when the left clamping grabbing plate 51 and the right clamping grabbing plate 52 clamp the film roll, the film material is extruded from the hollowed-out block 5-3, so that the film material can be prevented from being extruded and wrinkled and damaged, and the film material and the left clamping grabbing plate 51/the right clamping grabbing plate 52 realize full-area contact, so that the clamping effect is enhanced.
The change in diameter of the rolls is usually two, the first is a difference in length of the wound film material, in which case the roll diameter changes considerably, e.g. the roll diameter has a 3-4cm change at 150 m and 200 m length; the second case is where the film material is of different length but of different type and thickness, in which case the change in diameter of the film roll is small, around 1 cm. When the change of the film roll diameter is large, the left/right gripping and grabbing plate 51/52 needs to be replaced, when the change of the film roll diameter is small, the left/right sliding mechanism 31/32 needs to be slightly adjusted, the bottom plate 11 is provided with the waist-shaped hole 11-1 extending in the left/right direction, the bottom plate 11 and the track plate 2-2 are fixedly connected through the fastener arranged in the waist-shaped hole 11-1, the positions of the left/right sliding mechanism 31/32 can be adjusted, and then the positions of the left/right gripping and grabbing plate 51/52 are adjusted.
It should be noted that, the front end and the rear end of the frame 1 are both provided with a rolling structure 6, the rolling structure 6 is in a plate-shaped structure and is used for pressing down on the film roll, and when the left clamping grabbing plate 51/the right clamping grabbing plate 52 moves along the circumferential direction of the film roll, the left clamping grabbing plate 51/the right clamping grabbing plate 52 and the film roll can be prevented from sliding along the left-right direction due to touching of the film roll, so that clamping is affected.
In addition, the clamping device is also provided with an air path protection module, and a control mode of combining a mechanical valve with a threaded cylinder is adopted. In actual operation, the manual valve W1 controls the left clamping grabbing plate 51/the right clamping grabbing plate 52 to be opened and closed by matching two groups of manual valves, and the manual valve W2 controls the auxiliary lifting action. When the manual valve W2 is in the down shift position, the manual valve W1 can be arbitrarily shifted, and when the manual valve W2 is in the up shift position, the manual valve W1 is in a protection state, and the left gripping grabbing plate 51/right gripping grabbing plate 52 does not operate when the shift position is arbitrarily shifted.
