Description

Zipper strip pre-expanding machine Technical Field The utility model belongs to the technical field of zipper strip processing equipment, and relates to a zipper strip pre-expanding machine. Background In the production process of the fastener tape, a pre-expander is required to be used for conveying the fastener tape, and the pre-expander is required to straighten, i.e., pre-expand, the fastener tape. Regarding the working principle of the pre-expander, reference may be made to a pre-expander for zipper strips provided in patent document No. 202220337587.5, which comprises a driving roller device disposed on a workbench and comprising at least two groups of driving roller assemblies sequentially spaced along the conveying direction of the zipper strips, each group of driving roller assemblies comprises a first driving roller and a second driving roller located above the first driving roller, and the first driving roller and the second driving roller respectively act on the upper and lower sides of the zipper strips to be processed, so as to convey the zipper strips forward, wherein the speed of the driving roller assemblies located in front driving the zipper strips to move forward is greater than that of the driving roller assemblies located behind driving the zipper strips to move forward. The spacing between the drive rollers in the transverse direction is used for the passage of the zipper, which in the prior art is fixed, and when the zipper on the zipper strip is large, the drive rollers crush the zipper easily. Disclosure of Invention The utility model aims at the problems existing in the prior art, and provides a zipper strip pre-expander, which aims at solving the technical problem of how to adjust the interval between roller shafts. The aim of the utility model can be achieved by the following technical scheme: The utility model provides a zipper strip pre-expander, includes the frame, be provided with mount pad one and mount pad two in the frame, be provided with initiative roller one and driven roller one that can link on the mount pad one, be provided with initiative roller two and driven roller two that can link on the mount pad two, still be provided with the drive in the frame initiative roller one pivoted driving piece one, its characterized in that, mount pad one or/and mount pad two movable mounting is in the frame, be connected with the spline between initiative roller one and the initiative roller two, initiative roller one or initiative roller two can for the spline removes. In the fastener chain pre-expander, a driving part I drives a driving roll shaft I to rotate, a driven roll shaft I is driven by the driving roll shaft I to rotate, meanwhile, a driving roll shaft II drives a driven roll shaft II to rotate through a spline, the driving roll shaft II and the driven roll shaft I which synchronously rotate press one side of a fastener chain and drive the fastener chain to move forwards, the driving roll shaft II and the driven roll shaft II which synchronously rotate press the other side of the fastener chain and drive the fastener chain to move forwards, the driving roll shaft I and the driving roll shaft II are oppositely arranged with a gap therebetween, the driven roll shaft I and the driven roll shaft II are oppositely arranged with a gap therebetween, and a zipper on the fastener chain passes through the gap. The first driving source drives the mounting seat to move, or the driving source drives the mounting seat to move with the mounting seat to move, so that the interval between the first driving roll shaft and the second driving roll shaft in the horizontal direction and the interval between the first driven roll shaft and the second driven roll shaft in the horizontal direction can be adjusted, the corresponding adjustment interval is adjusted according to the size of a zipper on the zipper strip, and the zipper rolling device is good in adaptability and capable of well avoiding the zipper from being crushed. The spline can be fixed on the first driving roll shaft, and can move relative to the second driving roll shaft at the moment. In the zipper strip pre-expander, the spline comprises a cylindrical shaft body, a plurality of bosses are arranged on the outer wall of the shaft body, the bosses extend along the axial direction of the shaft body and are uniformly distributed along the circumferential direction of the shaft body, the end parts of the first driving roll shaft and the second driving roll shaft are respectively provided with a containing groove which is adaptive to the shape of the spline, and one end and the other end of the spline are respectively connected in the containing groove of the first driving roll shaft and the containing groove of the second driving roll shaft. The boss can enough increase the intensity of spline, and after the spline was installed at initiative roller, also can carry out spacingly to the spline in circumference, and the boss is a p
