As further improvement of the utility model, described roller adjusting device also comprises bolt shaft, the first gear, the second gear and spiral multiturn potentiometer, described bolt shaft is coaxially connected to thread spindle outer end, the first gear is arranged in bolt shaft and uses screw fastening, described spiral multiturn potentiometer is arranged on housing by mounting bracket, the second gear is arranged on the central shaft of spiral multiturn potentiometer, and the second gear is meshed with the first gear.
As further improvement of the utility model, described roller bearing assembly comprises supporting base, bearing, spacer ring, back-up ring and end cap, supporting base is arranged in the installing hole on printing press wall board, roller end is arranged in supporting base by two bearing supportings, between two bearings, by spacer ring, separate, the bearing of inner side props up spacing by back-up ring, the bearing in outside compresses spacing by end cap.
compared with prior art, advantage is the utility model:the utility model simple and ingenious structure, can fine adjustment and calculate the axial location of roller, realizes accurately axially chromatography object.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that A-A in Fig. 1 is to cutaway view.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2: the roller adjusting device of the axial chromatography of printing machine in embodiment is mainly comprised of parts such as housing 3, thread bush 4, thread spindle 5, worm gear 6, worm screw 7, bolt shaft 8, the first gear 9, the second gear 10, spiral multiturn potentiometer 11, guide plate 12, fairlead 13 and motors 14.
As shown in Figure 1 and Figure 2, described roller 1 is arranged in the installing hole on printing press wall board by 2 supportings of roller bearing assembly, described roller bearing assembly 2 is mainly comprised of supporting base 2a, bearing 2b, spacer ring 2c, back-up ring 2e and end cap 2d, supporting base 2a is arranged in the installing hole on printing press wall board, roller 1 end is arranged in supporting base 2a by two bearing 2b supportings, between two bearing 2b, by spacer ring 2c, separate, the bearing 2b of inner side props up spacing by back-up ring 2e, the bearing 2b in outside compresses spacing by end cap 2d; Roller 1 and roller bearing assembly 2 can move axially in installing hole.
As shown in Figure 1 and Figure 2, described housing 3 is fixed by screws in printing press wall board outside, motor 14 is arranged on housing 3, the output shaft connecting worm 7 of motor 14, worm screw 7 and worm gear 6 engagements, thread spindle 5 is located in worm gear 6 centers and is connected with worm gear 6 with key, and thread bush 4 is assemblied on the thread segment of thread spindle 5, and thread bush 4 is connected by screw on the supporting base 2a in roller bearing assembly 2; Described printing press wall board inner side is provided with fairlead 13 by screw, on described roller bearing assembly 2, be connected with guide plate 12, guide plate 12 is provided with the pilot hole suitable with fairlead 13, and fairlead 13 matches with guide plate 12, roller bearing assembly 2 can be moved axially but can not rotate.
In addition, in order accurately to measure the displacement of roller 1, the utility model adopts spiral multiturn potentiometer 11 to detect the rotation number of turns of thread spindle 5, thereby calculates the axially-movable distance of roller 1.The installation of spiral multiturn potentiometer 11 and applicable cases are as shown in Figure 1, described bolt shaft 8 is coaxially connected to thread spindle 5 outer ends, the first gear 9 is arranged in bolt shaft 8 and uses screw fastening, described spiral multiturn potentiometer 11 is arranged on housing 3 by mounting bracket, the second gear 10 is arranged on the central shaft of spiral multiturn potentiometer 11, and the second gear 10 is meshed with the first gear 9.
During concrete application, motor 14 drives worm screw 7 to rotate, and worm screw 7 drives worm gear 6 to rotate, worm gear 6 drives thread spindle 5 to rotate by key, because fairlead 13 has limited the rotation of roller bearing assembly 2, thereby also limited thread bush 4, rotates, thread bush 4 can only axially-movable, thereby drives a version rod to move axially; Because thread spindle 5 is connected with spiral multiturn potentiometer 11 with the second gear 10 by the first gear 9, helical potentiometer just can detect by gear drive the rotation number of turns and the direction of thread spindle 5, thereby measure the axially-movable position of edition rod, thereby reach accurately axial chromatography object.
