Detailed Description

The utility model provides a rolling device, includes inflatable shaft subassembly 1, and inflatable shaft subassembly 1 one side is connected with left cylinder assembly 2, and inflatable shaft subassembly 1 opposite side is connected with three-jaw oil pressure chuck 5, and inflatable shaft subassembly 1 below is provided with shallow assembly 4, and shallow assembly 4 one side is provided with frame assembly 3.

Further, left cylinder assembly 2 includes cylinder 2.2, and 2.2 below of cylinder is provided with cylinder supporting seat 2.5, and 2.5 one side of cylinder supporting seat is connected with lead screw 2.1, and 2.5 opposite sides of cylinder supporting seat are provided with the top 2.3 of location cone to the top 2.3 of location cone is provided with three jack catch 2.4 as the center.

Further, the air-expanding shaft assembly 1 comprises an air-expanding shaft 1.2, a pole piece 1.3 is arranged on the air-expanding shaft 1.2, two sides of the air-expanding shaft 1.2 are respectively connected with a left sleeve 1.1 and a right sleeve 1.4, the lower portions of the left sleeve 1.1 and the right sleeve 1.4 are connected to a V-shaped frame 3.1, a supporting plate 3.2 is arranged below the V-shaped frame 3.1, a cross plate 3.3 is arranged below the supporting plate 3.2, a positioning iron rod 3.4 is arranged below the cross plate 3.3, rollers 3.7 are arranged at the bottom end of the cross plate 3.3, a cross plate support 3.5 is connected below the cross plate 3.3, a plurality of wheels 3.6 are arranged below the cross plate 3.3, a guide rail 3.10 is connected above the wheels 3.6, a push handle 3.9 is connected above the wheels 3.6, and a lifting cylinder 3.8 is connected between the cross plates 3..

Before the inflatable shaft assembly 1 is not placed, the air cylinder 2.2 is at the limit position of the left end of the air cylinder, the 3 clamping jaws 2.4 are in a released state, and the clamping head of the three-jaw oil pressure clamping head 5 is in a released state. The difference reducing mechanism in the trolley assembly is positioned at the lower limit position in the vertical direction. Firstly, the pole piece inflatable shaft assembly 1 wound with the pole piece to be rolled is manually lifted to the V-shaped frame 3.1, and the left sleeve 1.1 and the right sleeve 1.4 are supported by the V-shaped frame 3.1. Then the trolley is moved to the front end of the frame assembly along the guide rail 3.10, and two positioning iron rods 3.4 at the front end of the trolley assembly are enabled to be propped against the positioning plate, so that the positioning of the inflatable shaft assembly 1 is realized. And then, the differential reduction mechanism in the trolley assembly drives the inflatable shaft assembly 1 on the V-shaped frame 3.1 to rise to the central axis positions of the left end cylinder assembly 2 and the three-jaw oil pressure chuck 5, so that the axial positioning of the inflatable shaft assembly 1 is completed.

The 3 jaws on the cylinder 2.2 do not work in this process. When the pole pieces in the unwinding device are completely rolled and need to be unloaded, the trolley assembly is pushed to a proper position to complete the positioning of the trolley assembly and the air inflation shaft in a similar working mode. At this point, the V-shaped mount 3.1 has contacted the left and right sleeves 1.1, 1.4 in the inflatable shaft assembly 1. The three-jaw oil pressure chuck 5 is loosened, the left end cylinder drives the 3 jaws 2.4 to clamp the left annular groove of the left sleeve 1.1 tightly, the air expansion shaft assembly 1 is driven to move left on the V-shaped frame 3.1 along the axial direction through the lead screw 2.1, the jaws are loosened after the air expansion shaft assembly is moved to a certain position, and then the air expansion shaft assembly is driven to move left to the limit position of the left end through the lead screw 2.1. At the moment, the unreeled air expansion shaft assembly 1 is completely supported by the V-shaped frame 3.1, then the differential reducing mechanism of the trolley assembly moves downwards, and finally the trolley is withdrawn, so that the reel changing work of the whole set of unreeling mechanism is completed. Similar to the unwinding method in the winding operation.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
