[0035] The use process of the present invention is as follows: the technicians in this field first place the bags to be printed on the top of the workbench 1 on the left side, and the protective corners around them can support and protect them, and then the first motor 36 can drive the first motor shaft 4 to rotate, and when the first motor shaft 4 rotates, it can drive the driving wheel 2 to rotate, and the driving wheel 2 will drive the driven wheel 8 at the other end to rotate around the fixed shaft 7 through the conveyor belt 11, at this time, the conveyor belt 11 can be realized. The circular rotation, when the conveyor belt 11 rotates, it will drive the workbench 1 to rotate through the connecting block 12 fixedly connected to the side wall, and then drive the bags on the upper end to rotate, first passing through the first printing assembly 10, and at this time the second hydraulic cylinder 25 can work The second hydraulic column 23 is driven to slide downward, and a hydraulic component is provided on one side of the mimeograph plate 14 and the mimeograph box 27. At this time, the operation of the hydraulic component on the inner wall causes the mimeograph plate 14 to slide outward, and causes the mimeograph plate 14 to slide to the lower end of the rubber head 22. At this time, when the second hydraulic column 23 slides downward, it can drive the rubber head 22 to slide downward and print on the upper end of the mimeograph plate 14, so that the pattern or text on the upper end of the mimeograph plate 14 can be clearly printed on the lower end of the rubber head 22. At this time, the third hydraulic cylinder 38 can drive the third hydraulic column 37 to slide downward, and drive the printing plate 40 to slide downward, so that the printing plate 40 is immersed in the middle of the mimeograph box 27, so that the water-based light oil is printed on the side of the printing plate 40 with the pattern, and then slides upward. At this time, the hydraulic component continues to The second hydraulic cylinder 25 works to drive the second hydraulic column 23 to slide downward, and the rubber head 22 can be clearly printed on the surface of the bag. Even if the surface of the bag is provided with protrusions and edges, the material of the rubber head 22 itself will not cause uneven patterns. At this time, the third hydraulic cylinder 38 works to make the third hydraulic column 37 slide downward, so that the printing plate 40 can clearly print the pattern or text on the surface on the mimeograph plate 14 to increase the clarity. When the bag is printed, the bag continues to slide and moves to the drying assembly 5. At this time, the air pump 28 can absorb air from the middle of the air inlet pipe 29, and discharge the air to the upper end, so as to be discharged through the two ends of the drying box 21, and the heating tube 30 works to heat at this time, and the maximum temperature of the heating tube 30 can only reach about 50° and cannot be higher, and the air blown by the air pump 28 will be directly blown into the middle of the drying box 21, and the heat will be discharged through the two ends of the drying box 21, and blown on the surface of the luggage to dry and fix the text and pattern printed on the surface. At this time, the luggage continues to rotate to the bottom of the flip assembly 6, and the first hydraulic cylinder 32 at this time can drive the first hydraulic column 19 to slide up and down, and the belt can slide the two clamping plates 16 downward. When sliding to both sides of the luggage,At this time, the electric telescopic component 35 will drive the two clamping plates 16 to clamp and fix the luggage, and the rubber pads at one end of the two clamping columns 34 will be close to the two sides of the luggage to better protect the luggage. After clamping, the first motor 36 will drive the clamping column 34 to rotate, and it will stop after rotating 180°, so that the luggage can be flipped. The two motors used in this article are servo motors, which are controlled by the control device, which is convenient for arbitrary stopping and working. Then the electric telescopic component 35 works to make the two clamping plates 16 slide to both sides and leave the two sides of the luggage, and the first hydraulic column 19 slides upward to make the clamping plates 16 leave the two sides of the luggage. After the luggage is flipped, it will continue to work through the second printing component 10, and the other side of the luggage will be printed in the same way, and then continue to slide through the second drying, so as to complete the printing process of the luggage. Finally, when the second drying is completed, the luggage can be taken down, which increases the efficiency of printing and greatly improves the printing effect.
