Abstract
The utility model discloses a kind of folding machine draw rollers press nips, comprise the pinch roller one and pinch roller two that are oppositely arranged, pinch roller one and pinch roller two are set to cylinder, and the outer circumference surface of described pinch roller one is provided with the plastics trim ring be fixedly connected with, and the outer circumference surface of described pinch roller two is provided with embossing.The technique effect that the utility model is useful is: because the pinch roller outer circumference surface of in press nips is provided with the plastics trim ring be fixedly connected with, utilize the elastic compression printing of plastics trim ring, effectively can reduce the impression in printing.
Description
Technical field
The utility model relates to the folding machine in a kind of offset printing rotary printing device, particularly relates to a kind of folding machine draw rollers press nips.
Background technology
At present, no matter roll sanction formula folding machine or impact type folding machine, generally below set square, be provided with the two pairs of draw rollers axles arranged up and down, every bar draw rollers axle is arranged with keep at a certain distance away two the draw rollers pinch rollers be fixedly connected with draw rollers axle, four pinch rollers on a pair draw rollers axle are oppositely arranged respectively, form two press nips, for paper is drawn in folding cylinder smoothly.The pinch roller of prior art is made up of metallic material, is generally made up of steel, and its external cylindrical surface is provided with annular knurl lines.Because each press nips printing product (being generally newspaper) is applied with certain pressure, inevitably leaves impression on the surface of printing, affect the aesthetic measure of printing, time serious, also can crush printing.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides a kind of folding machine draw rollers press nips that can reduce impression.
The utility model solves the problems of the technologies described above adopted technical scheme: folding machine draw rollers press nips, comprise the pinch roller one and pinch roller two that are oppositely arranged, pinch roller one and pinch roller two are set to cylinder, the outer circumference surface of described pinch roller one is provided with the plastics trim ring be fixedly connected with, and the outer circumference surface of described pinch roller two is provided with embossing.
The technique effect that the utility model is useful is: because the pinch roller outer circumference surface of in press nips is provided with the plastics trim ring be fixedly connected with, utilize the elastic compression printing of plastics trim ring, effectively can reduce the impression in printing.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model;
Fig. 2: be the I portion enlarged partial sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
As shown in the figure, folding machine draw rollers press nips, comprise the pinch roller 1 and pinch roller 22 that are oppositely arranged, pinch roller 1 and pinch roller 22 are set to cylinder, the outer circumference surface of described pinch roller 1 is provided with the plastics trim ring 3 be fixedly connected with, and the outer circumference surface of described pinch roller 22 is provided with embossing 4.
As further improvement, the embossing 4 of the outer circumference surface of described pinch roller 22 is set to vertical bar shaped.The impression of the embossing annular knurl shape embossing printing product compared to existing technology of vertical bar shaped will lack.
The outer circumference surface of described pinch roller 1 is provided with dovetail furrow 5, and the inner peripheral surface of described plastics trim ring 3 is provided with the dovetail form projection 6 matched, and realizes being fixedly connected with of pinch roller 1 and plastics trim ring 3.Another kind of technical scheme be pinch roller 1 outer circumference surface on be set to dovetail form projection, the inner peripheral surface of plastics trim ring 3 is set to the dovetail furrow matched, and also can reach same effect.
Described pinch roller 1 is integral by mold injection with described plastics trim ring 3.
