Abstract
Provided are an annular continuous grinding machine and annular continuous grinding method for processing the surfaces of printing rubber blankets. The whole roll of printing rubber blankets are all fed into the annular continuous grinding machine through a blanket storage roller, the printing rubber blankets are sewed into a closed loop by a sewing mechanism, and the printing rubber blankets are fed into a grinding head device through a power roller driven by a variable frequency motor to be ground annularly and continuously for three times. Due to the fact that the whole roll of printing rubber blankets are in a closed loop shape in a grinding process, the roll diameter change in winding and unwinding is avoided. After tension is well adjusted by a gravity tension roller and a balance weight block, the tension is stable in the whole processing process. Furthermore, an adjusting structure is simple. Due to the fact that blanket guidance in the annular grinding process is removed, the sewed portions of the printing rubber blankets are flat, the grinding accuracy is guaranteed, and the scrap of the head portions and the tail portions of the printing rubber blankets is reduced. Due to the fact that the three times of grinding is carried out circularly and continuously, the printing rubber blanket rolls are prevented from being transported fro and back. Thus, the grinding accuracy is guaranteed, the product rejection rate is reduced, and the work efficiency is improved.
Description
Technical field
The present invention relates to printing blanket processing technique field, particularly a kind of sand roll-type continuous grinding machine technical field, be applied to the continuous grinding processing of printing rubberized fabric surface.
Background technology
In the production process of printing blanket, last operation carries out grinding to the surface of printing blanket, and printing blanket generally will carry out three grindings, and secondary is roughly ground and once refined, reach the set quota with the flatness and surface roughness that ensure printing blanket, meet the demand of printing.At present, the continuous grinding machine for printing blanket surfacing is all one end feeding, other end rewinding, carries out single grinding, as shown in Figure 2: unwinding rack 13, printing blanket 15, slewing rollers 1, grinding head device 7, sand roller 8, feed rolls 9, rolling frame 14.During grinding, the blanket of rolling is placed on and unwinding rack delivers to sand roller through slewing rollers carries out grinding, then through slewing rollers from rolling the rolling frame of the other end, three times and so forth, complete the grinding process on whole printing blanket surface.The defect that this processing method exists is mainly: printing blanket is after a grinding, to move down from rolling frame, relay again on the unwinding rack of opposite side, start grinding process next time, one volume printing blanket is about 60 meters ~ about 120 meters, weigh 100 kilograms ~ about 200 kilograms, therefore time-consuming, effort, efficiency is low; For ensureing the grinding accuracy of printing blanket, the tension force making printing blanket keep constant is needed in grinding process, unwinding rack and rolling frame are equipped with tension control mechanism, but the retractable coil coil-diameter ratio of printing blanket when grinding is about 1: 3, therefore the precision that tension force controls comparatively is difficult to ensure card, and equipment investment is large; When carrying out the grinding of printing blanket by current method, the head of one volume printing blanket and afterbody are all stitched with and draw cloth, when grinding printing blanket head and afterbody, draw cloth to be connected with rolling frame and unwinding rack, to ensure normal transmission and the tension force of printing blanket, but because the physical characteristic of drawing cloth and printing blanket is inconsistent, their suture site can produce out-of-flatness phenomenon under certain tension force, affect the precision of grinding, generally all can cause the product rejection of about 0.5 meter at head, afterbody.
Summary of the invention
The object of the invention is to for overcoming above-mentioned defect, from the angle of technique, the structure of above-mentioned printing blanket continuous grinding machine being improved, design a kind of can make printing blanket three subsurface grinding process circulation complete continuously; Tension force constant in grinding process can be kept; And in grinding process, cancel ring type continuous grinding machine and the ring type continuous grinding method of drawing the printing blanket Surface Machining of cloth.
Its technology is achieved in that and comprises frame, grinding head device, sand roller, feed rolls, slewing rollers, carrying roller, live roll, variable-frequency motor, margin to seam mechanism, storage cloth rewinder roll, gravity tensioning roller, balancing weight, deviation rectification roller, unwinding rack, rolling frame is interior, it is characterized in that: the frame front of described ring type continuous grinding machine is provided with grinding head device, sand roller and feed rolls is included in grinding head device, live roll is arranged in frame by bearing, driven by frequency control motor through electromagnetic clutch, storage cloth rewinder roll is fixed in frame by bearing, the rear portion of frame is provided with margin to seam mechanism, slewing rollers are arranged in frame by bearing, gravity tensioning roller is provided with in the middle of slewing rollers, idler roller has adjustable balancing weight, deviation rectification roller is provided with in the middle of slewing rollers,
Its method for grinding is: the printing blanket that entire volume about 60 meters ~ 120 meters is long all once enters ring type continuous grinding machine through storage cloth rewinder roll, printing blanket is seamed into a closed ring by margin to seam mechanism, printing blanket is sent into grinding head device and is carried out continuous three grindings of ring type by the live roll driven by variable-frequency motor, after each grinding process completes, the grinding depth of sand roller is regulated by feed rolls, regulate grinding speed by variable-frequency motor, three times Grinding Cycle Command completes continuously;
Three times described circulation continuous grindings, comprise secondary corase grind, a fine grinding;
The quantity of described storage cloth rewinder roll is in 5 ~ 10 right scopes;
Front secondary corase grind circulation continuous grinding in three times described circulation continuous grindings, grinding depth controls between 0.03mm ~ 0.06mm, and wire velocity control is between 2000mm/min ~ 2500mm/min;
Fine grinding in three times described circulation continuous grindings completes Posterior circle in the grinding of secondary corase grind and completes continuously, and grinding depth controls between 0.02mm ~ 0.04mm, and wire velocity control is between 500mm/min ~ 1000mm/min.
Implement the obvious advantage after this technology and effect is: due to entire volume printing blanket in grinding process be one closed ring-like, without coil diameter change during unwinding and rewinding, after adjusting tension force by gravity tensioning roller and balancing weight, whole process tension force is steady, and adjust structure is simple; Draw cloth owing to eliminating in circulation continuous grinding process, the suture site of printing blanket is smooth, ensure that grinding accuracy, decreases printing blanket head, the scrapping of afterbody; Due to three times, Grinding Cycle Command carries out continuously, without the need to carrying printing blanket volume back and forth.Therefore, ensure that grinding accuracy, decrease product percent defective, improve operating efficiency.
