Abstract
The utility model relates to an arc-shaped guide roller used on a printing machine for decorative paper, and aims at providing an arc-shaped guide roller which has the advantages of effectively improving the printing product quality, and being simple in structure and convenient for manufacturing. The technical scheme is as follows: the arc-shaped guide roller of the printing machine is provided with a cylindrical roller surface. The arc-shaped guide roller is characterized in that a shaft of the guide roller is shaped like an arc which changes uniformly, and is positioned on the same plane. Any cross section of the guide roller has a same structure. The guide roller is made of stainless steel.
Description
Technical field
The utility model relates to a kind of deflector roll, especially the arc deflector roll that uses on the facing paper printing machine.
Background technology
Deflector roll is the conventional components on the printing machine; Usually need to be equipped with a large amount of deflector rolls on the intaglio press, so that paper is sent to next part (for example: paper is transported to the baking oven from printing machine version roller position, so that the printing ink on the rapid draing paper) from a part of equipment.
What adopt on the intaglio press usually is water color ink (ink viscosity is 13-20 second); Paper can expand to vertical and horizontal after sucking water color ink very soon, and especially lateral expansion is more; If there is not stronger lateral steering device, paper is very easy to crumple.
Conventional deflector roll structure is cylindrical, and the lateral steering active force of this kind deflector roll is not strong; During use, paper is easy to squeeze heap to the middle part of deflector roll and crumples, and causes the positive and negative of paper to form tangible longitudinal stripe, just becomes waste product when serious.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improvement of printing machine deflector roll is provided, and this deflector roll should be able to effectively improve printing product quality, and have simple in structure, make characteristics easily.
The technical solution adopted in the utility model is: printing machine arc deflector roll has the roll surface of tubular; The axis that it is characterized in that described deflector roll is the arc of even variation, and this axis is in the same plane.
The structure of arbitrary cross section of this deflector roll is all identical.
This deflector roll adopts stainless steel to make.
The beneficial effects of the utility model are: because the utility model can be eliminated the paper wrinkle phenomenon fully, thereby can effectively improve printing quality; In addition, this change structure is also comparatively simple, easy to make, and cost is also lower.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is the installation position schematic diagram of the utility model on press oven.
Fig. 3 is the structural representation of existing deflector roll.
The specific embodiment
As shown in Figure 2, all deflector rolls 2 of installing on the printing machine rotate (driving mechanism omits among the figure), and keep identical linear velocity by drive mechanism; So just can drive paper z travels forward (direction as shown by arrow D) regularly.
The change that the utility model is done is: make at least one deflector roll (the normally deflector roll of press oven 5 downsides) wherein into arc deflector roll 1 (showing 2 arc deflector rolls among the figure), the axis of this deflector roll is the arc of even variation, and this axis (promptly with a planes overlapping) in the same plane; The flexibility of arc deflector roll can determine as required, and the flexibility A of arc deflector roll (being the distance of the axial connecting line of the axle center of middle part and two-end part) is 8～18mm usually.General, the arc deflector roll can be made into uiform section structure (be in the deflector roll arbitrary cross-sectional structure all identical); And this deflector roll can only be fixedly mounted on the frame (bending direction of arc deflector roll should be vertical with the sheet movement direction) and can not rotate, and need not driving mechanism.
For strengthening anti-wear performance, this deflector roll adopts stainless steel to make (stainless steel cylinder).
Operation principle of the present utility model is: because the roll surface of this deflector roll is an arc, paper becomes moistening soft after stamping water color ink, will be opened by brute force when being pulled by the arc deflector roll, and then eliminate the phenomenon that paper is crumpled fully.Through practice test, can obtain satisfied effect.
Claims (3)
1. printing machine arc deflector roll has the roll surface of tubular; The axis that it is characterized in that described deflector roll (1) is the arc of even variation, and this axis is in the same plane.
2. printing machine arc deflector roll according to claim 1 is characterized in that arbitrary cross section of this deflector roll (1) is all identical.
3. printing machine arc deflector roll according to claim 2 is characterized in that this deflector roll adopts stainless steel to make.
