[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] See also Figures 1 to 4 The axial adjustment mechanism of the anilox roller of the printing and dyeing machine of the present invention is used to adjust the anilox roller connected between the driving side wall plate 100 and the operating side wall plate (not shown in the figure); the axial adjustment mechanism includes an axial adjustment plate 1, an axial guide mechanism, an axial adjustment motor 6, a ball screw mechanism and a limiting mechanism.

[0026] The axial adjustment plate 1 is arranged parallel to the outer side of the driving side wall plate 100, and the upper and lower parts of the axial adjustment plate 1 are respectively provided with a mesh roller shaft through-hole and a wire rod through-hole; the bearing for supporting the driving side shaft head 10 of the mesh roller is installed in the mesh roller shaft through-hole; two wire rod support bearings 30 are installed in the wire rod through-hole, and the two wire rod support bearings 30 are separated by a flange in the middle of the wire rod through-hole.

[0027] The axial guide mechanism includes a guide rail mounting bracket 2, a guide sleeve 3 and a guide rail seat 4; wherein the guide rail mounting bracket 2 is located parallel to the lower side of the anilox roller and includes an inner section, a flange ring, a first outer section and a second outer section connected in sequence from the inside to the outside; the inner section is inserted into the mounting hole of the driving side wall plate 100; the flange ring is mounted on the outer surface of the driving side wall plate 100 by a number of screws; the outer diameter of the first outer section is greater than the outer diameter of the second outer section; a thin-walled steel sleeve 20 is sleeved on the outer circumference of the second outer section; the guide sleeve 3 is fixedly sleeved on the outer circumference of the thin-walled steel sleeve 20 of the second outer section of the guide rail mounting bracket 2; the guide sleeve 3 is fixedly sleeved on the outer circumference of the thin-walled steel sleeve 20 of the second outer section of the guide rail mounting bracket 2; The rail seat 4 is an open sleeve with an inner circle and an outer square. Five threaded blind holes are provided on one open end face of the guide rail seat 4 at intervals along the length direction of the guide rail seat 4, and five through holes are provided on the other open end face that are coaxial with the five threaded blind holes. First, the guide rail seat 4 is sleeved on the outer circumferential surface of the guide sleeve 3, and then the opening of the guide rail seat 4 is fastened by five connecting bolts 41. A gasket 42 is provided between the two open end faces so that the guide rail seat 4 can slide axially along the guide sleeve 3. The guide rail seat 4 is connected to the inner side surface of the axial adjustment plate 1 by four screws 40 located at the four corners in a one-to-one correspondence.

[0028] The axial adjustment motor 6 is coaxially installed on the outer surface of the axial adjustment plate 1 through the motor seat and the axial adjustment hole; the motor seat includes four pile heads 61 fixed on the outer side surface of the axial adjustment plate 1 and a motor mounting plate 62 fixed on the outer end surface of the four pile heads 61.

[0029] The ball screw mechanism is arranged in the inner cavity of the guide rail mounting bracket 2. The outer end of the screw 31 in the ball screw mechanism passes through the two screw support bearings 30 in the screw through-hole of the axial adjustment plate 1 and is connected to the rotating shaft of the axial adjustment motor 6 through the coupling 60. The two screw support bearings 30 in the screw through-hole are limited to the outside of the screw 31 by the shaft shoulder and the retaining ring 3A on the screw 31; the flanged nut 32 in the ball screw mechanism is fixed to the outer end surface of the guide rail mounting bracket 2 by screws.

[0030] The limiting mechanism includes a limiting pile head 70, a limiting screw 71 and two pairs of limiting nuts 72; wherein, the limiting pile head 70 is vertically fixed on one end face of the guide rail seat 2 and close to the driving side wall plate 100, and a screw through-hole parallel to the screw rod 31 is provided on the limiting pile head 70; the limiting screw 71 is vertically fixed on the outer side of the driving side wall plate 100 and is slidably passed through the screw through-hole of the limiting pile head 70; the two pairs of limiting nuts 72 are both installed on the limiting screw 71 and are located on the inner and outer sides of the limiting pile head 70 correspondingly.

[0031] Since the guide rail seat 4 slides on the guide sleeve 3, lubricating oil needs to be added between the guide rail seat 4 and the guide sleeve 3. Therefore, an oil filling hole 4A connected to the inner hole is provided on the outer surface of the guide rail seat 4 to facilitate lubrication of the guide sleeve 3, so that the guide rail seat 4 can be adjusted without obstruction or pause.

[0032] The working principle of the axial adjustment mechanism of the anilox roller of the printing and dyeing machine of the present invention is as follows: when the axial adjustment motor 6 is working, it will drive the screw 31 in the ball screw mechanism to rotate, and the guide rail mounting bracket 2 and the guide sleeve 3 are fixed, so the nut 32 in the ball screw mechanism fixed on the outer end surface of the guide rail mounting bracket 2 also does not move, so that the screw 31 moves axially with the two screw support bearings 30. Since the two screw support bearings 30 are embedded in the screw through-holes of the axial adjustment plate 1, the two screw support bearings 30 drive the axial adjustment plate 1 and the guide rail seat 4 connected to the axial adjustment plate 1 to slide axially along the thin-walled steel sleeve 20 of the guide rail mounting bracket 2, and then the axial adjustment plate 1 drives the driving side shaft head 10 of the anilox roller to move axially, thereby achieving the purpose of axial adjustment of the anilox roller. By sliding the guide rail seat 4 on the guide rail mounting bracket 2, the stability of the axial adjustment plate 1 during movement can be ensured. When the guide rail seat 4 slides on the guide rail mounting bracket 2, the limiting pile head 70 will also synchronously slide axially on the limiting screw 71. The two pairs of limiting nuts 72 limit the sliding amount of the limiting pile head 70, thereby limiting the axial adjustment amount of the anilox roller.

[0033] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by the claims.
