TECHNICAL FIELD
[0001] The present application relates to the technical field of pad printing, in particular to a glass bottle surface printing machine. BACKGROUND
[0002] As a flexible printing process, pad printing occupies an important position in irregular object printing due to its characteristics of sticking ink on the rubber head and transferring it to the surface of the product. Its core advantage is that it can adapt to complex curved surfaces by deforming the rubber head to fit different radii and accurately present the preset pattern, so it is widely used in small and special-shaped product processing. However, when facing flat-shaped glass bottles with curved surfaces, especially when different patterns need to be printed on both sides, the limitations of pad printing become apparent. Although the overall shape of such bottles is flat, the surfaces on both sides are not flat but have a certain arc transition, which poses a great challenge to positioning. Traditional positioning methods are difficult to stabilize and fix the bottle, and slight deviation will cause pattern misalignment, directly affecting printing accuracy. More importantly, double-sided printing requires manual or mechanical turning, which not only increases the operation steps, but also further reduces efficiency due to positioning errors. In actual production, the slight shaking of the bottle during the turning process may cause pattern alignment deviation, and repeated clamping and adjustment will also prolong the processing time of a single bottle, resulting in limited overall production capacity. At the same time, multiple operations also increase the probability of ink contamination and rubber head wear, resulting in a high rate of defective products. Therefore, for the double-sided pad printing needs of flat-shaped and curved glass bottles, an efficient printing device needs to be designed. SUMMARY

Specifically, in use, the unprinted bottle body 12 is conveyed by the conveying belt 11, and when the bottle body 12 moves to the end of the conveying belt 11, the bottle body 12 will automatically fall into the support plate 22. Due to the structure of the flat bottle body 12, the bottle body 12 will naturally present a horizontal structure on the push plate 24 of the support plate 22, then the first driving device 25 is used to drive the push plate 24 and the bottle body 12 to move upwards, so that the bottle body 12 is between the first clamping block 26 and the second clamping block, then the second driving device 28 is used to drive the first clamping block 26 and the second clamping block to move close to each other and clamp the two ends of the bottle body 12 (after clamping, the push plate 24 descends to the original position), then the printing device 30 above the bottle body 12 is used to perform pad printing on the surface of the bottle body 12, after completing the single-sided printing, the third driving device 29 drives the bottle body 12 to rotate 180 degrees through the first clamping block 26, and then the other side is printed, after completing the printing, the first clamping block 26 and the second clamping block are loosened to the bottle body 12, so that the bottle body 12 is naturally discharged.

Specifically, the second motor 292 drives the first clamping block 26 to rotate by 180 degrees through the second transmission belt 293, thereby driving the bottle body 12 to rotate by 180 degrees. In addition to using a transmission belt to drive, gear transmission, universal joint transmission, chain wheel and chain transmission, etc. can also be used, wherein the second motor 292 needs to use a high-precision servo motor.
[0022] The first clamping block 26 in the embodiment is rotationally connected to the upper end of the first sliding block 281, and the second clamping block is rotationally connected to the upper end of the second sliding block 282; the third driving device 29 comprises a second driven wheel 291 arranged on the first clamping block 26, a second motor 292 fixedly arranged on the side of the first sliding block 281, a second driving wheel arranged on the output shaft of the second motor 292, and a second transmission belt 293 used to connect the second driving wheel and the second driven wheel 291.

Specifically, since the patterns on both sides of the bottle body 12 are usually different, a pair of rubber heads 33 are needed to be used to print the patterns on both sides of the bottle body 12 respectively, wherein the rubber head 33 first sticks the ink of the corresponding pattern on the ink source 34, and then uses the fourth driving device 35 and the fifth driving device 36 to drive to move to the surface of the bottle body 12 for printing, when one rubber head 33 is pressed on the surface of the bottle body 12, the other rubber head 33 is just attached to the ink source 34 for ink absorption operation, which can effectively improve the printing efficiency, wherein the ink source 34 is an ink plate containing a specific groove structure, wherein the shape of the groove on the ink plate is the same as the shape to be printed, the oil is sprayed on the ink plate, the oil will enter the groove, then the rubber head 33 contacts the ink plate, and the oil in the groove is absorbed, so as to realize the transfer of the pattern. The structure containing the structure can also be used in the form of conventional pre-made patterns on the roll material, and the rubber head 33 can be used to stick the pattern on the roll material, and the structure of the conventional can be used, and no specific requirements are made.
[0024] The first and second levers 352 are connected to each other via a lever 354, wherein the lever 354 is secured to the first and second levers 355.

Specifically, the second telescopic cylinder 351 drives the pair of pads 33 to move back and forth vertically, enabling the pads 33 to repeatedly apply ink and print. Because the pads 33 only need to switch between upper and lower limits in the vertical direction, a pneumatic cylinder can be used for the second telescopic cylinder 351. The third motor 363 rotates the second screw 362, which in turn drives the slide 38, via the drive block 361, to reciprocate along its axial direction. Its structure is similar to a ball screw.
