The specific embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing the utility model:
The controlled spreader of this static pressure subregion by the controlled roller of static pressure subregion 1, hydraulic means 2, control device 3, back flow roll 4, go up material roller 5, bowed roller 6, coatings tank 7, deflector 8, frame 9 and constitute; The top of frame 9 is equipped with back flow roll 4 through bearing; One side of back flow roll 4 is equipped with the controlled roller 1 of static pressure subregion; The opposite side of back flow roll 4 is equipped with bowed roller 6; The bottom of back flow roll 4 is equipped with material roller 5, and the controlled roller 1 of static pressure subregion meshes with back flow roll 4 respectively with last material roller 5, and a side of last material roller 5 is equipped with deflector 8 and coatings tank 7.
The controlled roller 1 of described static pressure subregion is made up of roller shell 11, steel alloy mandrel 12, pressurizing piston 13 and rolling bearing 14; The two ends of roller shell 11 are installed on the steel alloy mandrel 12 through rolling bearing 14, and steel alloy mandrel 12 is installed on through oscillating bearing 16 on the bearing block 15 at two ends, through the fixing steel alloy mandrel 12 of mandrel location-plate 17; And adjustment pressurizing piston 13 is with respect to back flow roll 4 directions; Evenly be divided into several region through roller shell 11 in the total length of nip, pressurizing piston 13 is evenly distributed in the roller shell 11, through forming the liquid static-pressure support oil film between the inwall of pressurizing piston 13 and roller shell 11; Make roller shell 11 be suspended in rotation on the steel alloy mandrel 12; There is not mechanical wear, freedom from repairs, the life-span is long.
The signal feedback end of the controlled roller 1 of static pressure subregion connects control device 3 through lead, and the pressurizing piston 13 of the controlled roller 1 of static pressure subregion is connected with hydraulic means 2; The amount of deflection that the input pressure of regulating each pressurizing piston 13 through hydraulic means 2 changes roller shell 11 in order to the deflection deformation that accurate counteracting is caused by the controlled roller 1 of static pressure subregion and 4 linear pressures of back flow roll, realizes accurately adjusting banner coating weight.
The controlled spreader of this static pressure subregion belongs to the long spreader that is detained; Paper through last material roller expectation amount after; Through changing the linear pressure between controlled roller 1 of static pressure subregion and the back flow roll 4, can regulate the holdup time, the holdup time prolongs the formation that can thicken and improve the coating filter cake; Improve coverage, can significantly improve glossiness, smoothness and whiteness simultaneously.The controlled roller 1 of static pressure subregion can play compression to the bossing of paper under high load capacity, and coating is further improved the level of coverage of bossing.
The controlled spreader of this static pressure subregion can carry out both macro and micro two aspects to the banner coating weight to be regulated, at first the rotating speed through the controlled roller 1 of adjustment static pressure subregion and the banner coating weight is carried out the macroscopic view adjusting with linear pressure between the back flow roll 4; Feed back the pressure of the corresponding single static pressure piston of microcosmic adjustment again through the deviation signal of closed-loop control device; Because the piston space between adjacent, can not produce defectives such as coating streak apart from being 80mm, thereby can accurately control the banner quality of paper.The coating weight adjustable range can reach 4 ~ 20g/m
2, speed of a motor vehicle 1000m/min can adjust according to coated paper kind and coating quality, satisfies the requirement of multiple coated paper.
When the controlled spreader of this static pressure subregion is worked; After paper enters into material roller 5 expectation coating contents through bowed roller 6; A coating part is just transferred to material roller; Coating another part to coatings tank 7, can be adjusted deflector 8 angles to adapt to the different speed of a motor vehicle through deflector 8 upper end feed backs, through the banner linear pressure of regulating between controlled roller 1 of static pressure subregion and the back flow roll 4 the coating holdup time is controlled.The controlled roller 1 of static pressure subregion of running can play compression to the bossing of paper under high load capacity, and coating is further improved the level of coverage of bossing, has guaranteed product quality.Because no wing or scraper wearing and tearing, the broke amount behind the paper is resolved in effective minimizing, and can promptly regain the uniformity of coating weight cross direction profiles after the disconnected paper, has therefore reduced production cost, has significantly improved the overall efficiency of paper machine.Simultaneously, level and smooth, evenly, the coating weight of cross direction profiles also make coating machine and calender and rewinding function normally, operation swimmingly.Thoroughly solved prior art and on page, be difficult for the dry fold that produces because of uneven banner coating weight causes coating, big to the parts loss, have a strong impact on the production efficiency and the quality of paper machine, and the problem of broken, disconnected paper phenomenon often takes place.The controlled spreader coating of this static pressure subregion good uniformity, production efficiency is high, and quality of finished product good is practiced thrift cost, and is easy to operate, can satisfy the requirement of multiple coated paper.
The above is the specific embodiment of this utility model; The above-mentioned flesh and blood that illustrates not the utility model constitutes restriction; Under the those of ordinary skill of technical field after having read this specification, can make an amendment or be out of shape the above-mentioned specific embodiment, and do not deviate from the essence and the scope of the utility model.
