Abstract
The utility model discloses a paper tensioning device of an unwinding unit of a gravure press, which comprises an unwinding arm. A pair of connecting plates is symmetrically arranged on the outer surface of the unwinding arm, a pair of support plates is respectively fixed to one end of each connecting plate by bolts, a pair of nuts is symmetrically disposed on inner sides of upper ends of the support plates, screws are arranged in the nuts, gaskets are disposed at lower ends of the screws, sleeves are movably supported on the gaskets, each sleeve is in clearance fit with the corresponding screw, a pair of bearing blocks is symmetrically disposed on inner sides of the sleeves, paper guide rolls are supported by the bearing blocks, and handles are disposed at upper ends of the screws. By means of rotating the handles, the screws ascend, descend and drive the gaskets, the gaskets drive the sleeves and the bearing blocks to ascend and descend, the bearing blocks drive the paper guide rolls to ascend and descend, accordingly, drooping unwound paper is tensioned by the aid of ascending and descending of the paper guide rolls, and paper runs stably assuredly during printing. The paper tensioning device is simple in structure, convenient in installation and stable and reliable in operation.
Description
Technical field
The utility model relates to intaglio printing press manufacturing line auxiliary device, is especially unreeling between unit and splicing unit, prevents the device of paper tenesmus.
Background technology
Advantages such as intaghlio printing is a kind of as typography, and is real, bright-colored with its printing product China ink bed thickness, that degree of saturation specific humidity is high, the forme press resistance rate high, print quality is stable, print out rate is fast occupy extremely important status in printing packaging and picture and text publishing area; The intaglio printing press manufacturing line generally comprises and unreels unit, splicing unit, print couple unit etc.Because the splicing unit is far away with the distance that unreels the unit; Unreel paper because action of gravity produces tenesmus, crimp that produces in tension variation that in body paper rewinding process, produces and the body paper course of conveying or the like reason; Cause to unreel in the paper feed process and form wave phenomenon in printing; When fluctuation is big, cause the cross cutting paper feed to have some setbacks, influence printing quality.
In the prior art, the device that addresses the aforementioned drawbacks is not arranged.
By on can know that above-mentioned existing intaglio printing press manufacturing line unreels the unit, on reality is used, obviously have defective and exist, and remain to be improved.
Thus, the improving of the above-mentioned defective of the utility model thoughts is that the spy concentrates on studies and cooperates repetition test, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.
Summary of the invention
To the deficiency of prior art, the utility model aims to provide a kind of intaglio printing press and unreels unit paper tightening device, to guarantee that in the process of unreeling, paper feed is steady.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts: a kind of intaglio printing press unreels unit paper tightening device, comprises unreeling arm; Be symmetrical set a pair of gusset piece at the said lateral surface that unreels arm, through a pair of back plate of bolt, be symmetrical set a pair of nut in inboard, said back plate upper end at said gusset piece one end; Screw rod is set in nut, fixedly installs packing ring in said screw rod lower end, freely-movable bearing has sleeve on said packing ring; It between said sleeve and the screw rod free-running fit; Be symmetrical set pair of bearing in said sleeve inboard, said bearing block support dancing roll is provided with handle in said screw rod upper end.
After adopting said apparatus, through turning handle, lifting screw; Screw rod drives packing ring, and packing ring drives sleeve and bearing seat goes up and down, and bearing seat drives dancing roll and goes up and down; Up-down through dancing roll like this, tenesmus unreel the paper tensioning, guarantee that paper feed is steady in the printing process; This device can also be through bolt on loosening gusset piece and the back plate, the swivel bearing plate, thus regulate dancing roll and unreel the front and back position that paper contacts.
The utility model is simple in structure, and is easy for installation, and working stability is reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the A of Fig. 1 is to view;
In the accompanying drawing: 1 unreels arm 2 gusset pieces 3 bolts 4 back plates 5 packing rings 6 sleeves 7 bearing seats 8 screw rods 9 nuts 10 handles 11 dancing rolls 12 unreels paper.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, shown in Figure 2, at the lateral surface that unreels arm 1, two gusset pieces 2 are symmetrical set an end of gusset piece 2 through screw retention; At gusset piece 2 other ends; Through bolt 3 difference fixed support plate 4, bolt 3 also plays the S. A. effect, and bolt 3 need be enough to fastening gusset piece 2 and back plate 4; Slide all right bigger packing ring bolt 3 of adapted relative size in order to prevent to produce between gusset piece 2 and the back plate 4; Weld a pair of nut 9 respectively in inboard, two back plates, 4 upper end, nut 9 height are greater than 50 millimeters, and nut 9 is complementary with screw rod 8; At screw rod 8 lower end solid water flush weld packing rings 5, freely-movable bearing sleeve 6 on packing ring 5, screw rod 8 pass sleeve 6 endoporus; Be free-running fit between sleeve 6 and the screw rod 8, be symmetrical set pair of bearing 7 in sleeve 6 inboards, the axle at dancing roll 11 two ends is supported in the bearing seat; Dancing roll 11 aluminium alloys are processed, and in light weight, rotary resistance is little; Bearing is a rolling ball bearing, in screw rod 9 upper ends handle 10 is set, turning handle 10; Screw rod 9 just can drive dancing roll 11 and rise or descend, thereby dancing roll 11 tensionings unreel paper 12, so just can guarantee in the gravure manufacturing line printing process; Paper feed is steady, steady quality, and product qualified rate is high.
This device is flexible, can be up and down or front and back regulate dancing roll 11, guarantee dancing roll 11 at any time with unreel paper 12 tensionings.
The above; Be merely the specific embodiment of the utility model embodiment; But the protection domain of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model discloses, and conspicuous variation or replacement all should be encompassed within the protection domain of the utility model.
