Abstract
The utility model relates to a printing machine, more specifically a double screw paper press roller used during paper strip traction. The utility model provides the design proposal that an elastic surface layer is covered outside a tubular framework. The utility model is characterized in that the surface of the surface layer is provided with opposite spiral ripples. The surface of the surface layer is provided with two threads which have opposite spiral directions and intersect mutually or two threads which have opposite spiral directions and do not intersect or partially intersect. The framework is arranged on a main shaft by a bearing, and both ends of the main shaft are respectively arranged at the middle of a connecting seat. The paper press roller is provided with the ripples capable of promoting the paper strips to generate force pointing two directions in the rolling process, and thus, the paper strips can be flatwise laid. As a consequence, the utility model avoids the wrinkle phenomenon of the paper strips easily generated in the rolling process.
Description
Technical field
The utility model relates to printing machinery, specifically a kind of air roll used when the traction paper tape.
Background technology
Paper tape must provide power by carry-over pinch rolls in printing process, and the air roll assembly need be set, and pressured paper bowl is pressed in the certain frictional force of generation on the carry-over pinch rolls, and is non-slip on carry-over pinch rolls to guarantee paper tape, makes chromatography accurate.Existing carry-over pinch rolls are as shown in Figure 1: two bolts are installed respectively on two blocks of wallboards 15, hinged cylinder 2 on the bolt below being positioned at, extension bar 3 is arranged on the piston rod of cylinder 2, the other end of extension bar 3 and Connection Block 8 are hinged, the other end of Connection Block 8 is articulated in and is positioned on the top bolt, main shaft 9 is installed at the middle part of Connection Block 8, at the middle part of main shaft 9 air roll 16 is installed.Because the surface of this air roll is smooth General Purpose Rubber material, when platen, easily make paper tape " snakelike phenomenon " occur, have influence on printing quality.
Summary of the invention
The purpose of this utility model is to design a kind of double helix air roll, on this air roll, be provided with ripple, this ripple can make paper tape produce the power of pointing to both sides in the roll extrusion process, makes the paper tape tiling, thus the fold phenomenon of having avoided paper tape when roll extrusion, to be prone to.
According to design provided by the utility model, outside the skeleton of tubular, cover the rubber-like top layer, it is characterized in that: helical ripple in opposite directions is set on the surface on top layer.
It is opposite on the surface on top layer the hand of spiral to be set, and cross one another two screw threads, or the hand of spiral is opposite but non-intersect or disjoint two screw threads of part.Skeleton utilizes bearing to be installed on the main shaft, and the two ends of main shaft are installed on the middle part of Connection Block respectively.One end of Connection Block is articulated on the upper pin, and the other end and the extension bar of Connection Block are hinged, and the other end of extension bar is connected with the piston rod of cylinder, and cylinder is articulated on the lower bearing pin.Last lower bearing pin is installed on respectively on the wallboard of both sides.Axle sleeve is arranged on upper pin, and Connection Block is enclosed within on the axle sleeve.
The utility model has the advantages that: simple in structure, result of use is good.Owing to be provided with the opposite double-spiral structure of hand of spiral on the top layer of air roll, when platen, not only increased frictional force, and paper tape also is subjected to the identical active force of both sides to the left and right, make paper tape in the roll extrusion process, be tending towards tiling, thereby avoided wrinkling, improved printing quality.
Description of drawings
Fig. 1 is original platen assembly roll structure figure.
Fig. 2 is an air roll assembly assumption diagram of the present utility model.
The specific embodiment
As shown in the figure: cover rubber-like top layer 12 outside the skeleton 11 of tubular, 12 surface is provided with helical ripple 13 in opposite directions on the top layer.During platen, this helical ripple 13 in opposite directions can produce the active force to both sides to paper tape, makes paper tape be tending towards tiling, can be not wrinkling, thus improved printing quality.
That the hand of spiral is set is opposite on 12 surface on the top layer, and cross one another two screw threads.Or the hand of spiral is opposite but non-intersect or disjoint two screw threads of part.Described helical ripple 13 can have varied, is not limited in several form mentioned in this article.
Skeleton 11 utilizes bearing 10 to be installed on the main shaft 9, so that air roll rotates, the two ends of main shaft 9 are installed on the middle part of Connection Block 8 respectively, so that air roll is exerted pressure.One end of Connection Block 8 is articulated on the upper pin 5, and the other end of Connection Block 8 and extension bar 3 are hinged, and the other end of extension bar 3 is connected with the piston rod of cylinder 2, and cylinder 2 is articulated on the lower bearing pin 1.During work, cylinder 2 actions, its piston rod drives extension bar 3 actions, and extension bar 3 promotes Connection Block 8 and rotates around upper pin 5, and Connection Block 8 drives main shaft 9 again and air roll rotates around upper pin 5 together, and air roll is exerted pressure to paper tape.Last lower bearing pin 5,1 is installed on respectively on the wallboard 15 of both sides.Axle sleeve 6 is arranged on upper pin 5, and Connection Block 8 is enclosed within on the axle sleeve 6, so that Connection Block 8 rotates around upper pin 5.
