Abstract

The utility model relates to a special paper tube rolling machine, which comprises a motor, a speed reducer, a trailing bar, a hand wheel, a machine frame and three or more than three rollers. At least one roller is connected with the speed reducer, the surrounding surface of each roller is a convex spherical surface, core rods are arranged among the rollers, the surrounding surface of each core rod is composed of a plurality of concave spherical surfaces matched with the convex spherical surfaces of the rollers, and the number of the concave spherical surfaces is equal to the number of the rollers. The utility model is simple in operation, and is capable of processing special paper tubes with various specifications according to requirements, particularly square paper tubes, triangular paper tubes, etc.

Description

The Special paper tube mill

The utility model relates to a kind of milling train of processing profiled paper tube.

Existing milling train can only the processing metal pipe, and because the quality of circle paper tube is soft, elasticity is big, and is yielding, utilizes existing milling train to process.

The purpose of this utility model provides a kind of Special paper tube mill that circular paper tube can be processed into special-shaped paper tube.

The technical scheme that realizes above-mentioned purpose is: a kind of Special paper tube mill, comprise motor, reductor, planker, handwheel, frame and the roller more than three or three, have at least a roller to be connected with reductor, the side face of roller is protruding sphere, be provided with plug between roller and the roller, the side face of plug is made of several concave spherical surfaces that the protruding sphere with roller matches, and the number of the number of concave spherical surface and roller is identical.

After adopting technique scheme, the side face of roller is protruding sphere, be provided with plug between the roller, the side face of plug is made of several concave spherical surfaces that the protruding sphere with roller matches, and the number of concave spherical surface equates with the number of roller, like this, as long as the circular paper tube that will roll into puts plug, paper tube is under the effect of plug and roller, be pressed into and the plug corresponding shape by circular paper tube, after plug is taken out from paper tube, because the rebound effect that paper tube produces, just formed the special-shaped paper tube of square tube, triangle tube and other shape, easy to operate.

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Fig. 1 is the structural representation of first kind of embodiment of the utility model;

Fig. 2 is the cross-sectional schematic along A-A line of Fig. 1;

Fig. 3 is the cross-sectional schematic along B-B line of Fig. 1;

Fig. 4 is the structure enlarged diagram of roller among Fig. 1;

Fig. 5 is the structural representation of second kind of embodiment of the utility model.

As shown in Figure 1, 2, 3, a kind of Special paper tube mill comprises motor 7, reductor 6, planker 3, handwheel 2, frame 1 and four rollers 4, left and right two rollers 4 are connected with reductor 6, as active roller, on turning rolls 8, fixedly connected with frame 1 by bolt 9, nut 10 by turning rolls 8 as passive roller wheel bearing for upper and lower two rollers 4.The side face of roller is to be provided with plug 5 between 4-1, four rollers 4 of protruding sphere, and the side face of plug 5 is made of four concave spherical surfaces 5-1 that the protruding sphere 4-1 with roller 4 matches.

As shown in Figure 4, has annular knurl 12 on the side face of roller 4.Annular knurl 12 can increase the frictional force between roller 4 and the plug 5, improves the operating efficiency of milling train.

The operation principle of the Special paper tube mill of employing said structure is as follows: the circular paper tube that will roll into puts plug 5, starter motor 7, a left side, right two rollers 4 rotate under the drive of reductor, be enclosed within circular paper tube on the plug 5 on an adjusted good left side, push ahead under the pressure of right roller 4 and the turning effort, simultaneously, paper tube move and left, under the acting in conjunction of right active roller 4, on, following two adjusted good passive rollers 4 also rotate and the pressure rolling paper tube, last paper tube depresses to and the similar special pipe of plug 5 shapes in the acting in conjunction of roller 4 and plug 5, promptly finishes pressure rolling work.At this moment, roller 4 is stopped operating, plug 5 is withdrawn support 11, paper tube can be unloaded, produce resilience, become square (cross section is square) paper tube just because paper tube breaks away from plug 5 backs.

Rotate handwheel 2, planker 3 is moved, the gap variable between the left and right roller 4 is big or diminish.Spacing between the upper and lower roller 4 can be regulated by the bolt 9 on the frame 1, nut 10.Can regulate the power of extruding and regulate size, the wall thickness that the pressure rolling paper tube is treated in adaptation by regulating four spacings between the roller 4.

As shown in Figure 5, be another kind of embodiment of the present utility model, the number of roller 4 is three among the figure, wherein there are two rollers 4 to be connected with reductor, as active roller, on turning rolls 8, fixedly connected with frame 1 by adjusting bolt 9, nut 10 by turning rolls 8 as passive roller wheel bearing for the another roller.And the side face of plug 5 is made of three concave spherical surfaces 5-1, spacing between three rollers 4 also can be regulated by the bolt 9, the nut 10 that rotate handwheel 2 and regulate on the frame 1, all the other structures are similar with first kind of embodiment, and its operation principle is identical with first kind of embodiment.The paper tube that just processes is that cross section is leg-of-mutton paper tube.

The number of roller 4 is also more than four, and the side face of the plug 5 corresponding with it also can be made of the concave spherical surface more than four 5-1, and can process cross section like this is polygonal paper tube.

The utility model Special paper tube mill is simple to operate, can process the special-shaped paper tube of all size as required, particularly square paper tube, triangle paper tube etc.
