The above construction allows the steel sheet coil 36 to be fitted over the support plate 18 and thus mounted to the rotary shaft 16; the telescopic arm of the oil cylinder 30 extends forwards (only the embodiment in fig. 1 is taken as an example, the left side in fig. 1 is taken as the front, which is determined according to the direction of the inclined surface of the guide block 20, and is not necessarily required to extend forwards), the connecting rod 34 drives the push-and-pull slider 24 to move forwards, and the push-and-pull slider 24 drives the support plate 18 to move outwards through the matching of the inclined wedge block 26 and the guide block 20, so that tensioning is realized; fig. 1 shows two states of the telescopic arm of the oil cylinder 30 extending forward and returning.
Further, a through shaft hole 38 is provided in the rotary shaft 16 along the axial direction thereof, 1 rotary joint 40 is provided on the rear end surface of the rotary shaft 16, and the rotary joint 40 communicates with the cylinder 30 through at least one inner oil pipe (not shown) provided in the shaft hole 38. The rotary joint 40 is a connection structure, one end of which is fixed and the other end of which is rotated, and can ensure communication, and is a mature product on the market, and therefore is not shown in detail. An oil tank 42 and an oil pump 44 are disposed in the housing 12, the oil pump 44 is connected to the oil tank 42 and a plurality of distribution valves 46, each distribution valve 46 is connected to the rotary joint 40 through an outer oil pipe (not shown), and is communicated with an inner oil pipe through the rotary joint 40. The oil cylinder 30 has various specifications, and only one oil pipe is used for pressurizing and injecting oil through the oil pump 44 to drive the telescopic arm to extend forwards; after oil is drained, the telescopic arm is reset under the action of external force; and the other oil pipe is connected with the oil pipe, and then drives the telescopic arm to extend forwards, and the other oil pipe drives the telescopic arm to retreat. The present invention can select different oil cylinders 30 according to the requirement, and the oil is supplied according to the requirement through the distributing valve 46. If the oil cylinder 30 with two inner oil pipes is adopted, the rotary joint 40 also needs to be reasonably selected and matched according to needs, and creative labor is not needed to be made by ordinary technicians in the industry in the selecting and matching process.
A motor 48 is provided in the housing 12, and the motor 48 drives the rotary shaft 16 to rotate through a reduction gear 50 and a gear 52 provided on the rotary shaft 16.

The end of the supporting plate 18 is provided with a connecting portion 60 passing through the sliding slot 58, and the connecting portion 60 is provided with at least two rollers 62 located at two sides of the sliding slot 58. With this structure, the four support plates 18 can be movably fixed to the rotary shaft 16 without being released in the front-rear direction; the motor 48 then drives the rotating shaft 16 to rotate, which synchronously drives the supporting plate 18 to rotate, and further drives the steel sheet coiled material 36 thereon to rotate.
In one embodiment, the connecting rod 34 is provided with external threads, the push-up sliders 24 are provided with connecting holes (not shown) for the connecting rod 34 to pass through, and each push-up slider 24 is adjustably fixed to the connecting rod 34 by two front and rear nuts 64 screwed to the connecting rod 34. Therefore, the structure not only fixes the pushing and expanding slide block 24, but also can adjust the position of the pushing and expanding slide block 24 to adjust the magnitude of the expanding force, and is very convenient and easy to use. The pushing and expanding slide block 24 comprises a bottom plate 66 made of an arc-shaped copper plate, a wedge block 26 is fixed on the bottom plate 66 through screws, and the wedge block 26 is triangular.

The telescopic arm of the oil cylinder 30 is provided with a plurality of pin holes 72 with internal threads along the radial direction, and further comprises a pin 74 which can be in threaded connection with the pin holes 72. After the steel plate coiled material is sleeved on the supporting plate 18 and is tensioned, the pin 74 is manually locked, so that the position of the telescopic arm of the oil cylinder 30 can be fixed through physical contact, the situation that the tensioning fails due to the fact that the telescopic arm retracts when the rotating shaft 16 rotates due to oil leakage and the like is avoided, and the safety is improved. The threaded pin structure also effectively prevents the pin 74 from falling off during rotation of the rotating shaft 16.
Referring to fig. 7, in another embodiment of the present invention, based on the previous embodiment, a key slot 80 is formed on the wedge block 26, and a straight key (not shown) is formed on the guide block 20 to match with the key slot 80. When the inclined wedge block 26 slides up the guide block 20 along the inclined surface 22, the straight key is just clamped into the key groove 80, so that the inclined wedge block 26 and the guide block 20 cannot move relatively in the rotating process, and force can be directly transmitted between the inclined wedge block 26 and the guide block 20, so that the stress condition of the connecting rod 34 is improved (in the former embodiment, the connecting rod 34 is subjected to torsion applied to the inclined wedge block 26 by the guide block 20 in the rotating process), and the condition that the connecting rod is bent and deformed due to the large torsion in the rotating process is avoided.
Wherein, if the positions of the straight key and the key slot 80 are fixed and unchangeable, the straight key needs to be very accurate when being clamped into the key slot 80, otherwise, the straight key can not be clamped into the key slot 80, and the fault occurs. For this reason, in the present embodiment, the base 68 is a rectangular parallelepiped structure, the four side surfaces of the base 68 are provided with arc-shaped grooves 82, and the arc-shaped grooves 82 are provided with arc-shaped sliding rails 84; the cross section of the slide rail 84 is dovetail-shaped, the inclined wedge blocks 26 are provided with clamping grooves (not shown) matched with the slide rail 84 in shape, and the inclined wedge blocks 26 are movably clamped on one slide rail 84 through the clamping grooves; the two ends of the arc-shaped slot 82 are provided with a baffle plate 88, and each baffle plate 88 is provided with a spring 90 which is abutted against the inclined wedge block 26. The inclined wedge block 26 is arranged on the base 68 in a manner of moving left and right, when the inclined wedge block 26 slides on the guide block 20 along the inclined plane 22 and the straight key is clamped into the key slot 80, the front end of the key slot 80 is generally provided with a horn-shaped guide opening (not shown) for facilitating the clamping of the straight key, and meanwhile, the inclined wedge block 26 can slightly move left and right to match the entering of the straight key. After the straight key is inserted, because the guide block 20 is fixed on the support plate 18, the tapered wedge block 26 is fixed on the guide block 20 through the combination of the straight key and the key slot 80, and a stable structure is formed. The structure improves the stress condition of the connecting rod 34, solves the problem that the straight key is not easy to align with the key slot 80, and avoids the mechanical fault caused by the unsnapping of the straight key. The stop 88 and spring 90 are used for limit and return.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
