Abstract
The utility model discloses a knurling ring used for a folding machine, which is a cylindrical body. The utility model is characterized in that: knurling lines are arranged on the outer cylindrical surface; the cylindrical body is divided into a left semi-cylindrical body and a right semi-cylindrical body; the left semi-cylindrical body is fixedly connected with the right semi-cylindrical body through bolt. The utility model has the advantages that: since the cylindrical body is divided into the left semi-cylindrical body and the right semi-cylindrical body, only two bolts need to be loosened when shifting or adjusting position and the position can be adjusted or shifted; the utility model has convenient and swift operation and good maintainability.
Description
Technical field
The utility model relates to the folding machine in a kind of offset printing rotary printing equipment, relates in particular to a kind of used for folding machine annular knurl circle.
Background technology
At present, no matter roll sanction formula folding machine or impact type folding machine, the general two pairs of draw rollers axles arranging up and down that below set square, are provided with, on every draw rollers axle, be arranged with fixedly connected a pair of draw rollers, end in each draw rollers respectively is provided with an annular knurl circle (eight draw rollers have eight annular knurl circles), is used for paper is drawn in folding cylinder smoothly.Distance between the annular knurl circle is decided on the width of newspaper, needs often to adjust the position concerning the newspaper office that the newspaper width often changes.The cylinder (square-section annulus) that the structure of the annular knurl circle of prior art is as a whole, end face is fixedlyed connected with draw rollers with screw, external cylindrical surface is provided with the annular knurl lines, tight with cooperating of draw rollers axle or have a problem of rustiness because of annular knurl circle and draw rollers, very hard when adjusting position, for the very high newspaper printing enterprise of ageing requirement, there is the shortcoming of losing time, in addition, the annular knurl circle belongs to consumable accessory, need often to change, integrally-built annular knurl circle need disassemble draw rollers and draw rollers axle just and can change, and therefore also has the bad shortcoming of maintainability.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of used for folding machine annular knurl circle easily of regulating and change is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: used for folding machine annular knurl circle, it is a cylinder, be provided with the annular knurl lines at external cylindrical surface, described cylinder split is set to left semicircle cylindrical shell and right semi-circle cylindrical shell, and the left semicircle cylindrical shell is screwed with the right semi-circle cylindrical shell and is connected.
The utility model beneficial technical effects is: because the split of annular knurl circle is set to left semicircle cylindrical shell and right semi-circle cylindrical shell, when position adjustments or replacing, as long as unclamp two screws, can carry out position adjustments or replacing, thereby have advantage convenient to operation, that maintainability is good.
Description of drawings
Fig. 1: structural representation of the present utility model;
Fig. 2: be the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in the figure, used for folding machine annular knurl circle is a cylinder, is provided with annular knurl lines 1 at external cylindrical surface, described cylinder split is set to left semicircle cylindrical shell 2 and right semi-circle cylindrical shell 3, and left semicircle cylindrical shell 2 is fixedlyed connected with right semi-circle cylindrical shell 3 usefulness screw (not shown)s.
The left semicircle cylindrical shell 2 of present embodiment and right semi-circle cylindrical shell 3 are the step semicircle cylindrical shell of symmetry, on major diameter semicircle cylindrical shell 4, be provided with the annular knurl lines, be provided with screwed hole 6 or step through-hole 7 in minor diameter semicircle cylindrical shell 5 upper edges with dividing tangent plane 8 vertical direction, with screw left semicircle cylindrical shell 2 and right semi-circle cylindrical shell 3 are fixed on the draw rollers axle, fixed combinating surface is the endoporus of left semicircle cylindrical shell 2 and right semi-circle cylindrical shell 3 and the periphery of draw rollers axle.Its manufacturing process is to process the concentric integral barrel body of inside and outside circle and annular knurl lines 1 and screwed hole 6, step through-hole 7 earlier, cuts with the line cutting again.
Also be provided with the through hole 9 that the screw on position and the draw rollers end face is complementary on the end face of left semicircle cylindrical shell 2 and right semi-circle cylindrical shell 3 vertically, be used for left semicircle cylindrical shell 2 and right semi-circle cylindrical shell 3 further are fixed on the end face of draw rollers.
Claims (3)
