Abstract

The utility model relates to a linear guide double press roller, which comprises a support, a printing roller, a rubber covered roller, an air cylinder, connection blocks and sliding guide rails, wherein the connection blocks and the sliding guide rails are arranged on two ends of the rubber covered roller. The connection blocks are in sliding match with the sliding guide rails, the air cylinder is connected with the connection blocks, the rubber covered roller is rotatablely arranged between the connection blocks arranged on two ends of the rubber covered roller, and further provided is a steel roller which is rotatablely arranged between the connection blocks arranged on two ends of the rubber covered roller. The steel roller is jointed with the rubber covered roller, and the steel roller and the rubber covered roller are both matched with the connection blocks in linkage mode. By adopting the technical scheme, the linear guide double press roller is provided. When the rubber covered roller is driven to slide, deformation of the rubber covered roller can be avoided, and accordingly quality of printing is guaranteed.

Description

The line slideway twin pressure roller

Technical field

The utility model relates to the printing instrument field, particularly a kind of line slideway twin pressure roller.

Background technology

At present, existing a kind of line slideway twin pressure roller that is used to print, include support, version roller, rubber roll, be arranged on the slippage guide rail on the support, version roller, rubber roll all cooperate with the support rotation, the rubber roll two ends are provided with coupling block, rubber roll and coupling block are linked, and two coupling blocks cooperate with the slippage of slippage guide rail, also include to be used to drive the cylinder of two coupling blocks along the slippage of slippage guide rail, rotate by driven by motor version roller, control two coupling block slippages by cylinder, thereby regulate the distance between rubber roll and the version roller, make the moving rubber roll rotation of version roller strap realize presswork.

But, the line slideway twin pressure roller of this structure, because the length of rubber roll is generally long, by the slippage of air cylinder driven rubber roll the time, the middle part of rubber roll can produce certain deformation, thus the effect of influence printing.

Summary of the invention

The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of line slideway twin pressure roller, when driving the rubber roll slippage, can prevent that rubber roll from producing distortion, thereby can guarantee the quality of printing.

The technical solution of the utility model: a kind of line slideway twin pressure roller, include support, version roller, rubber roll, cylinder, be arranged on coupling block, the slippage guide rail at rubber roll two ends, described coupling block cooperates with the slippage of described slippage guide rail, described cylinder is connected with described coupling block, described rubber roll is rotatably provided between the coupling block at its two ends, also include the steel rider that is rotatably provided between the coupling block of rubber roll two ends, described steel rider and described rubber roll are fitted, and described steel rider, rubber roll all are linked with described coupling block.

Adopt technique scheme, by setting up steel rider, because described steel rider is rotatably provided between the coupling block of rubber roll two ends and steel rider and rubber roll applying, when cylinder is controlled coupling block along the slippage of slippage guide rail, described steel rider is also with the coupling block slippage, thereby can prevent that described rubber roll from producing deformation, and then guarantee the quality of printing.

Further setting of the present utility model: be equipped with locating shaft in the rubber roll, described rubber roll is connected through bearing with locating shaft, the coupling block at rubber roll two ends is provided with the hole of inserting for described locating shaft two ends, and described hole is the grooved hole that is provided with along the coupling block glide direction.

Adopt above-mentioned further setting, produce certain error because rubber roll adds trade union, by being provided with along the slotted hole of coupling block glide direction, can be so that the spacing between adjusting rubber roll and the version roller makes printing effect better.

Further setting more of the present utility model: be equipped with rotating shaft in the described steel rider, rotating shaft terminal all is connected through the coupling block of bearing with described rubber roll two ends.

Adopt above-mentioned further setting again, the rotation mode of this structure, simple in structure, reliable.

The specific embodiment

As Fig. 1, shown in 2, a kind of line slideway twin pressure roller, include support 1, version roller 2, rubber roll 3, cylinder 4, be arranged on the coupling block 5 at rubber roll 3 two ends, slippage guide rail 6, described slippage guide rail 6 vertically is arranged on the support 1, described coupling block 5 cooperates with described slippage guide rail 6 slippages, described cylinder 4 is connected with described coupling block 5, described rubber roll 3 is rotatably provided between the coupling block 5 at its two ends, also include the steel rider 7 that is rotatably provided between the rubber roll 3 two ends coupling blocks 5, described steel rider 7 is fitted with described rubber roll 3, described steel rider 7, rubber roll 3 all is linked with described coupling block 5, and moving up and down of described coupling block 5 drives steel rider 7, rubber roll 3 moves up and down.

For fear of the error that produces owing to rubber roll 3 processing, thereby the effect of influence printing, in the utility model specific embodiment, be equipped with locating shaft 8 in the rubber roll 3, described rubber roll 3 is connected through bearing 10 with locating shaft 8, the coupling block 5 at rubber roll 3 two ends is provided with the hole 51 of inserting for described locating shaft 8 two ends, and described hole 51 is the grooved hole that is provided with along coupling block 5 glide directions.

In the utility model specific embodiment, be equipped with rotating shaft 9 in the described steel rider 7, steel rider 7 is with rotating shaft 9 rotations, and rotating shaft 9 two ends all are connected through the coupling block 5 of bearing 10 with described rubber roll 3 two ends.

The operation principle of the utility model specific embodiment: described version roller 2 drives its rotation through external motor, drives coupling block slippage about in the of 5 by control cylinder 4, thereby regulates the spacing between rubber roll 3 and the version roller 2, reaches best printing effect.
