figure 3 is a view at the windup assembly of the present invention.

Detailed Description

As shown in the figure, the non-stop unreeling reel soft packing material offset printing machine comprises an unreeling assembly, an offset printing unit group and a reeling assembly which are sequentially arranged, wherein the offset printing unit group is offset printing units 4 which are arranged in an array mode, the unreeling assembly comprises a first unreeling seat 1 and a second unreeling seat 2 which are arranged on the left and right sides, a cutting knife 6 is arranged between the first unreeling seat and the second unreeling seat, squeezing wheels 10 are arranged on the two sides of the cutting knife 6, the squeezing wheels 10 are arranged on corresponding movable seats 7, the movable seats 7 are connected with corresponding horizontal driving assemblies, each horizontal driving assembly is a first air cylinder 9, and a piston rod of each first air cylinder 9 is connected with the corresponding movable seat 7. Unreel and be provided with storage component between subassembly and the offset printing unit group, the rolling subassembly includes the rotating turret 5, rotating turret 5 is connected with the transmission of rotation motor, be provided with first rolling seat 15 and second rolling seat 14 about on rotating turret 5, be close to rotating turret 5 and be provided with swing span 17, swing span 17 articulates in the frame, and be connected with first swing drive assembly, it is specific, first swing drive assembly is second cylinder 16, the piston rod of second cylinder 16 is articulated with swing span 17, be provided with rubber roll 18 and swing piece 20 on the swing span 17, be connected with cutter 21 on the swing piece 20, swing piece 20 is connected with second swing drive assembly. The second swing driving component is a third air cylinder 19, the cylinder body of the third air cylinder 19 is arranged on the swing frame 17, and the piston rod of the third air cylinder 19 is hinged with the swing block 20. The storage assembly comprises a storage rack 3, wherein upper warp winding rollers 11 are arranged on the upper portion of the storage rack 3 in an arrayed mode, a lifting seat 12 is arranged on the lower portion of the storage rack 3 in a sliding mode, and lower warp winding rollers 13 are arranged on the lifting seat 12 in an arrayed mode.

In the offset press, when the first unreeling seat 1 is close to the completion of unreeling, the extrusion wheel 10 close to the first unreeling seat 1 is controlled to move towards the cutting knife 6 to be matched with the cutting knife 6 to cut off the unreeled soft package material on the first unreeling seat 1, and simultaneously, the extrusion wheel close to the second unreeling seat 2 is controlled to be close to the cutting knife to extrude the soft package substrate which is drawn to the position and coated with glue on the second unreeling seat 2 and bond the soft package substrate with the unreeled part, so that the unreeling switching operation is realized, in addition, because the unreeling speed is relatively reduced in the switching process, the conveying tension of the soft package material is increased, the lifting seat 12 is pulled to be lifted, so that the soft package material stored between the upper and lower winding rollers is conveyed backwards, the unreeling stability is ensured, and after the reeling is completed, the unreeling roller on the second unreeling seat 2 can be normally unreeled, and the conveying tension of the soft package material is reduced, the lifting seat 12 descends under the action of gravity, so that the unreeled soft package material can be stored in the storage rack 3, and the rolling device is used when waiting for next roll changing and transferring, after the rolling of the rolling roller on the first rolling seat 15 is completed, the rotating frame 5 is controlled to rotate, the second rolling seat 14 is driven to move to a rolling station, meanwhile, the second air cylinder 16 drives the swing frame 17 to swing towards the second rolling seat 14, the third air cylinder 19 drives the swing block 20 to swing, so that the cutter 21 cuts off printed materials output by the offset printing unit and the rolling shaft on the first rolling seat 15, meanwhile, the printed materials are pressed by the press roller 21 to the rolling shaft on the second rolling seat 14, and the rolling and transferring operation is realized.

According to the structure, the two sets of the unwinding seat and the winding seat are arranged, and the pressing and cutting assembly is arranged in a matched mode, so that the base material can be wound and unwound without stopping, the smoothness of the whole work of the equipment is improved, and the printing efficiency is guaranteed.
