In a specific embodiment of the invention: the article placing groove 6 of one article placing unit is provided with a height adjusting unit 14 for enabling the supporting units 9 in each article placing unit to synchronously operate, the height adjusting unit 14 comprises an insulating column 1401 vertically installed at the bottom of the article placing groove 6 and a coil 1404 wound on the outer wall of the insulating column 1401 and provided with a conductive block 1402 at one end, the bottom of the lower supporting plate 901 is fixedly provided with a conductive rod 1403, and the bottom end of the conductive rod 1403 is bent towards the insulating column 1401 and is in contact with the coil 1404.

By adopting the technical scheme, in daily use, the height adjusting unit 14 in the object placing unit provided with the height adjusting unit 14 is electrically connected with the straight-moving cylinders 902 in other object placing units, when the straight-moving cylinder 902 in the object placing unit provided with the height adjusting unit 14 drives the lower supporting plate 901 to move up and down, one end of the conductive rod 1403 moves on the coil 1404, so that the electrified number of the coil 1404 is changed, the size of the resistor is changed, the starting time of the straight-moving cylinders 902 can be controlled through the value of the resistor, and the lifting heights of all the straight-moving cylinders 902 are the same.

The invention also discloses a printing process, which comprises the following steps in the specific embodiment of the invention: s1, charging: glass bottles are placed in each storage groove 6 one by one, two oppositely arranged clamping jaw air cylinders 703 are started to enable two pairs of clamping jaws 702 to be close to each other, a plurality of anti-skidding soft pads 13 arranged on the inner wall of a clamping plate 12, at one end, extending out of a telescopic pipe sleeve 1101, of a supporting rod 1104 are abutted against the surfaces of the glass bottles, a sliding block 1102 slides in the telescopic pipe sleeve 1101 to enable a first spring 1103 to be extruded and deformed to provide thrust, so that the anti-skidding soft pads 13 are in tight contact with the surfaces of the glass bottles, then two lifting air cylinders 801 are started to enable a rotary air cylinder 701 to descend into the storage groove 6, a straight air cylinder 902 is started to enable a lower supporting plate 901 to ascend until the top surface of an upper supporting plate 905 is abutted against the bottom surface of the glass bottles, a second spring 903 is deformed, a pressure sensor 904 arranged on the top surface of the lower supporting plate 901 is contacted with the bottom surface of the upper supporting plate 905, and an electric signal is sent out to enable the straight air cylinder 902 to stop running; s2, feeding: the bracket 3 slides on the base 1 along the longitudinal direction, and moves a row of object placing units fixed with glass bottles to the lower part of the electric slide rail 4;

s3, first-side printing: the printing nozzle 5 slides on the electric slide rail 4 and prints the surface of the glass bottle below the electric slide rail 4;

s4, turning: after the surfaces of the glass bottles in the row of storage units are printed, the straight-moving cylinder 902 drives the lower supporting plate 901 to descend until the upper supporting plate 905 moves to the position below the clamping jaw cylinders 703, then the two rotating cylinders drive the two clamping jaw cylinders 703 to synchronously rotate, the glass bottles are turned to the other side, then the straight-moving cylinder 902 is started to enable the lower supporting plate 901 to ascend until the top surface of the upper supporting plate 905 is abutted to the bottom surface of the glass bottles, the second spring 903 deforms, the pressure sensor 904 arranged on the top surface of the lower supporting plate 901 is contacted with the bottom surface of the upper supporting plate 905, and an electric signal is sent to enable the straight-moving cylinder 902 to stop running;

s5, second-side printing: the printing nozzle 5 slides on the electric slide rail 4 and prints the surface of the glass bottle which is positioned below the electric slide rail 4 and is turned over;

s6, whether to continue to turn over: if the printing on the other side is required to be continued, returning to the step S4, and if the printing is finished, entering the step S7;

s7, continuous feeding: the carriage 3 continues to slide on the base 1, the row of glass bottles which are printed leaves the position below the printing nozzle 5, the step S8 is executed, the next row of glass bottles which are not printed moves to the position below the printing device, and the step S3 is returned simultaneously;

s8, taking materials: the clamping jaw air cylinder 703 operates to enable the two clamping jaws 702 to move towards the direction away from each other until the anti-skid soft pad 13 is separated from the surface of the glass bottle, the straight-moving air cylinder 902 is started, the lower bearing plate 901 and the upper bearing plate 905 ascend to enable the glass bottle to leave the storage groove 6, a worker takes the glass bottle off the upper bearing plate, the second spring 903 resets, and the upper bearing plate 905 ascends to leave the pressure sensor 904;

s9, resetting: the lower supporting plate 901 is driven by the straight-moving cylinder 902 to descend, the lower supporting plate 901 and the upper bearing plate retract into the object placing groove 6, and the lifting cylinder 801 is started at the same time, so that the rotating cylinder 701 and the clamping jaw cylinder 703 move to the upper part of the object placing groove 6.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
