Abstract
The invention relates to a wide breadth flat belt compression roller, which comprises a core shaft and a sleeve pipe sleeved on the core shaft, wherein the sleeve pipe comprises a plurality of sections combined together, and the sections are connected with each other. The cross sections of the two ends of the shaft are round, and the cross sections of the rest parts are rectangular; one end of the sleeve pipe sleeved on the two ends of the core shaft is connected with the part with a round cross section of the core shaft through a bearing sleeve, while the other end is connected with the part with the rectangular cross section of the core shaft through a supporting sleeve; the sleeve pipe sleeved in the middle of the core shaft is connected with the part with the rectangular cross section of the core shaft through the supporting sleeve, and the adjacent supporting sleeves are connected with each other through a positioning sleeve; and a sliding gap is formed between the core shaft and the supporting sleeve. Because the sleeve pipe sleeved on the core shaft adopts a multi-section combined structure and a gap is formed between the supporting sleeve and the core shaft, the sleeve pipe can sag depending on the self weight and always press on a flat belt, and cannot generate bending as the prior integral sleeve pipe, and the normal running of the sleeve pipe is ensured, and the printing quality is also guaranteed.
Description
Technical field
The present invention relates to a kind of wide format printing machinery, the flat pattern band pressure roller on especially a kind of wide format printing machinery.
Background technology
At present, known flat belt press roller with wide breadth mostly is to be assembled by mandrel, the integral cannula, rolling bearing and the positioning sleeve that are sleeved on the mandrel.Owing to adopt integral cannula; Therefore when wide format is printed, tend to exist a deficiency, promptly under the situation of long distance, sleeve pipe is because the problem of deadweight; Tend to exist certain bending; So will cause sleeve pipe to seize up, the flat pattern band also just can not the compacting of view picture face, thus the direct quality of influence printing.
Summary of the invention
The objective of the invention is to existing pressure roller exist owing to casing buckling makes it to seize up, thereby cause the deficiency of printing quality difference, a kind of novel flat belt press roller with wide breadth is provided.
Technical scheme of the present invention is: a kind of flat belt press roller with wide breadth comprises mandrel and is enclosed within the sleeve pipe on the mandrel that described sleeve pipe is constituted by multistage, interconnects between sleeve pipe and the sleeve pipe.
Preferably, the cross section at said mandrel two ends is circular, and the cross section of remainder is a rectangle; Be sleeved between an end and the mandrel circular cross-section part of sleeve pipe at mandrel two ends and be connected, be connected through splicing sleeve between the other end and the mandrel square-section part through bearing holder (housing, cover); The sleeve pipe that is sleeved on the mandrel middle part is connected through splicing sleeve with mandrel square-section part, connects through positioning sleeve between the adjacent splicing sleeve; Between sleeve pipe and the splicing sleeve, be provided with bearing between sleeve pipe and the bearing holder (housing, cover).
Preferably, leave glade plane space between described mandrel and the splicing sleeve.
Preferably, bearing holder (housing, cover) and positioning sleeve are fixed on the mandrel by screw.
Beneficial effect of the present invention is: because the mandrel sleeve pipe that adopts multistage to combine; And remain with certain clearance between splicing sleeve and the mandrel; Therefore sleeve pipe can rely on the weight of self sagging, presses all the time and puts on the flat pattern band, and can not produce bending as integral cannula in the past; Thereby guaranteed the normal operation of sleeve pipe, printing quality has also obtained guarantee.

The specific embodiment
To specific embodiment of the present invention shown in Figure 4, a kind of flat belt press roller with wide breadth comprises mandrel 6 and is enclosed within the sleeve pipe 4 on the mandrel like Fig. 1, and described sleeve pipe 4 is constituted by multistage, interconnects between sleeve pipe 4 and the sleeve pipe 4; The cross section at mandrel 6 two ends is circular, and the cross section of remainder is a rectangle; Be sleeved between an end and the mandrel 6 circular cross-sections part of sleeve pipe 4 at mandrel two ends and be connected, be connected through splicing sleeve 3 between the other end and the mandrel 6 square-section parts through bearing holder (housing, cover) 1; The sleeve pipe 4 that is sleeved on mandrel 6 middle parts is connected through splicing sleeve 3 with mandrel 6 square-section parts, connects through positioning sleeve 8 between the adjacent splicing sleeve 3, between sleeve pipe 4 and the splicing sleeve 3, be provided with bearing 7 between sleeve pipe 4 and the bearing holder (housing, cover) 1; Leave glade plane space between mandrel 6 and the splicing sleeve 3; Bearing holder (housing, cover) 1 is fixed on the mandrel by screw 2, and positioning sleeve 8 is fixed on the mandrel 6 by screw 5.
During work, mandrel begins to rotate, and drives sleeve pipe simultaneously and rotates; During rotation, owing to have certain gap between splicing sleeve 3 and the mandrel, therefore; Sleeve pipe relies on the weight of self to fall automatically, makes each Duan Junneng contact with the flat pattern band, thereby reaches the purpose of whole compaction.
Claims (2)
1. a flat belt press roller with wide breadth comprises mandrel and is enclosed within the sleeve pipe on the mandrel, and it is characterized in that: described sleeve pipe is constituted by multistage, interconnects between sleeve pipe and the sleeve pipe; The cross section at said mandrel two ends is circular, and the cross section of remainder is a rectangle; Be sleeved between an end and the mandrel circular cross-section part of sleeve pipe at mandrel two ends and be connected, be connected through splicing sleeve between the other end and the mandrel square-section part through bearing holder (housing, cover); The sleeve pipe that is sleeved on the mandrel middle part is connected through splicing sleeve with mandrel square-section part, connects through positioning sleeve between the adjacent splicing sleeve; Between sleeve pipe and the splicing sleeve, be provided with bearing between sleeve pipe and the bearing holder (housing, cover); Leave glade plane space between described mandrel and the splicing sleeve.
