[0003] Glass product printing refers to equipment specially used for printing, printing or decorative pattern processing on the surface of glass products, by transferring colored inks, pigments and other printing materials to the surface of glass products in a precise manner, such as screen printing, digital inkjet printing, thermal transfer, pad printing and other methods.

[0004] In the process of realizing the utility model, the inventors found that the prior art has the following problems: 1.

However, most of these equipment lack workpieces for fixing during processing. When processing some bowl-shaped workpieces, most of them are mounted in grooves. Although it can prevent falling, it may cause the workpiece to move due to viscosity when it comes into contact with the rubber head; 2. Some pad printing equipment cannot be flexibly converted according to the shape of the workpiece and printing requirements. For example, some glassware, whose printing surface is different from the bowl, may not be placed directly in the groove, and then it is necessary to find a suitable fixture for installation.

The workpiece bearing seat 11 is located below the pad printing rubber head 6, and a workpiece fixing assembly 12 is provided on the surface of the workpiece bearing seat 11. A reverse lead screw 13 is rotatably connected inside the workpiece bearing seat 11, and auxiliary limit assemblies 14 are respectively provided at both ends of the workpiece fixing assembly 12, and the auxiliary limit assemblies 14 are slidably connected to the slide groove on the surface of the workpiece bearing seat 11.

[0027] A driving gear 1001 and an incomplete gear 1002 are rotatably connected inside the support base 10. The incomplete gears 1002 are respectively located at both ends of the workpiece support seat 11. The incomplete gears 1002 are integrally connected to the two ends of the outer wall of the workpiece support seat 11 through a shaft running through the axis.

[0028] The workpiece fixing assembly 12 includes a fixing ring 1201 and an adjusting ring 1202. The fixing ring 1201 is glued to a circular notch on the surface of the workpiece bearing seat 11. The adjusting ring 1202 is slidably connected to a fan-shaped slide groove inside the fixing ring 1201. The adjusting rings 1202 are connected by an annular spring 1203. The auxiliary limiting assembly 14 includes an outer support plate 1401 and an inner support plate 1402. The inner support plates 1402 are glued to one side of the outer support plate 1401 by springs. One end of the bottom of the outer support plate 1401 passes through the interior of the workpiece bearing seat 11 and is connected to the reverse nut on the surface of the reverse lead screw 13 by bolts.

[0029] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a plurality of springs glued to the steel plate mounting area 2 are provided at the edge of the mold fixing plate 3 adjacent to the steel plate mounting area 2, and the mold fixing plate 3 forms an elastic reset structure through the springs; the mold fixing plate 3 is lifted up by the elastic reset structure formed by the springs, and at the same time, one end of the mold fixing plate 3 is again attached to the mold mounted on the surface of the steel plate mounting area 2 under the action of the springs, fixing its surface to ensure that the pad printing rubber head 6 will not be displaced when it contacts it, and this elastic knot can adapt to molds of different sizes within a certain range, and combined with the surrounding edge structure on one side of the steel plate mounting area 2, the stability of the mold fixed on its surface is further increased.

[0030] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, one end of the pad printing platform 4 forms a transmission structure at the top of the steel plate mounting area 2 through the nut on the surface of the lead screw 9, and the other end of the pad printing platform 4 is slidably connected to the surface of the slide rod located above the machine base 1 through a slider, and the scraper 7 forms a lifting structure on the surface of the steel plate mounting area 2 through the second cylinder 8 and slides to fit the surface of the steel plate mounting area 2; the pad printing platform 4 is combined with the lead screw 9 and the slider structure on one side thereof to ensure the stability of its transmission process and reduce shaking and deviation, and the scraper 7 and the pad printing rubber head 6 are integrally connected through the pad printing platform 4. When the pad printing rubber head 6 absorbs ink through the transmission structure, the scraper 7 can hang off excess ink, effectively avoiding the possibility of excessive adsorption of the pad printing rubber head 6, ensuring the clarity and consistency of the printed pattern, and this synchronous driving method reduces the coordination problem between components and improves the stability of equipment operation.

[0031] In this embodiment, Figure 3 As shown, the pad printing rubber head 6 forms a lifting structure above the workpiece supporting seat 11 through the first cylinder 5; the lifting structure realized by the first cylinder 5 of the pad printing rubber head 6 can accurately control the contact and separation with the workpiece below, and can flexibly adjust its position according to the height of the processed workpiece.

[0032] In this embodiment, Figure 4As shown, the driving gear 1001 is provided with two groups and meshed with the incomplete gear 1002 respectively, and the incomplete gears 1002 are connected to the driving gear 1001 connected to the output end of the servo motor through one side thereof to form a transmission structure, and the workpiece support seat 11 forms a flip structure through the incomplete gear 1002; compared with some single processes that can only realize the printing processing of the pad printing rubber head 6 from the top at one angle, the flip structure realized by the driving gear 1001 and the incomplete gear 1002 allows the workpiece support seat 11 that clamps the workpiece to flip 90 degrees. When operating a bottle-like vessel, it is different from a bowl-like vessel, and its printing position is different. The purpose of this structure is to effectively avoid the time of replacing the fixture separately, so that the equipment can handle various types of workpieces, increase the versatility and application range of the equipment, effectively avoid the occurrence of position deviation problems that may be caused by reinstalling the fixture, and help to improve the accuracy and consistency of printing.

[0033] In this embodiment, Figure 5 As shown, the outer support plate 1401 and the inner support plate 1402 are both in an arc shape, and the inner support plate 1402 forms an elastic reset structure through a spring provided on the concave surface of the outer support plate 1401, and a relative transmission structure is formed between the auxiliary limit assembly 14 along the two ends of the workpiece fixing assembly 12 through a reverse screw 13, and at the same time, the midpoint position of the outer support plate 1401 and the inner support plate 1402 is located at the same horizontal position as the axis point of the workpiece fixing assembly 12; because when processing a bottle-shaped workpiece, its shape is different from that of a bowl-shaped workpiece, and its specifications are longer, the auxiliary limit assembly 14 that moves relative to each other on both sides can further increase the clamping force at both ends, and the outer support plate 1401 and The shape of the inner support plate 1402 can better fit the outside of the bottle-shaped container, provide multi-point clamping, and adjust the position and range of clamping through relative movement. The distribution position of the midpoint and the axis point helps to ensure that the center of gravity of the internal workpiece can remain consistent during clamping and operation, thereby making the workpiece more evenly stressed and avoiding instability or damage due to eccentricity. Furthermore, the elastic telescopic structure generated by the elasticity of the inner support plate 1402 can provide a certain cushioning when in contact with the workpiece, which can not only protect the surface of the workpiece from being damaged by excessive clamping, but also adapt to slight changes in the size of the workpiece to a certain extent, ensuring firmness during the clamping process.

[0034] In this embodiment, Figure 6As shown, the inner support plate 1402 and the adjustment ring 1202 are both made of rubber material, and the adjustment ring 1202 is fan-shaped and distributed in a ring shape in the internal slide groove of the fixed ring 1201, and the adjustment ring 1202 forms an elastic telescopic structure through the annular spring 1203, and an opening and closing structure is formed between the adjustment rings 1202; the adjustment ring 1202 drives the annular spring 1203 through its outer wall to adaptively telescope and open and close according to the size of the bottom of the workpiece, and better adapt to workpieces of different sizes. Compared with most direct mounting methods, it effectively avoids the possibility of loosening, and the parts of the equipment that are used to directly contact the surface of the workpiece are made of rubber material, which has a certain degree of softness and elasticity, and can reduce damage to the surface of the workpiece. The two groups of parts for fixing the workpiece are combined with the flipping structure of the workpiece support seat 11 to effectively avoid the tediousness of frequent replacement of the fixture, reduce the steps and time of operation, and thus improve the overall processing efficiency.

[0035] The use method and advantages of the utility model: When the daily glass product printing device is used, the working process is as follows:

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, first of all, it should be explained that in order to ensure the accuracy and stability during the printing process, the first cylinder 5 and the second cylinder 8 need to be connected to a pressure sensor (model SMC PSE540), which can monitor the pressure output of the first cylinder 5 and the second cylinder 8 in real time through an electrical connection control body. When it exceeds the set normal range, the external control system will automatically adjust and quickly restore the pressure to a suitable range. First, the operator places the engraved steel plate mold on the steel plate mounting area 2, with one side of it against the edge of the steel plate mounting area 2, and presses the mold fixing plates 3 at both ends of the steel plate mounting area 2 respectively. Under the elastic structure, one end of the mold fixing plate 3 is tilted up and the hand that releases the pressure is reset under the elastic structure to press against the two ends of the mold surface. The operator pours ink on the mold surface. Because the shape to be printed is engraved on the surface of the mold, the ink will flow into the notches formed by these shapes. The workpiece is placed inside the workpiece fixing component 12. When the workpiece is inserted into the workpiece, it will fit between the inner walls of the annular adjustment ring 1202. According to the size of the bottom of the workpiece and the action of the external annular spring 1203, the adjustment ring 1202 adjusts its opening and closing angle through an adaptive structure. If only a bowl-shaped workpiece is to be processed, the workpiece can be clamped by the workpiece fixing component 12. When processing bottle-shaped or other utensils that cannot be placed in the workpiece fixing component 12, turn on the power and drive the reverse screw 13 to make the two outer support plates 1401 move toward the workpiece under the relative motion structure and make the inner support plate 1402 fit against the outer wall of the workpiece. The rubber material can further increase The friction coefficient is increased to improve the clamping force. If a bottle container is clamped, the rotation of the driving gear 1001 installed with a servo motor on one side can drive the incomplete gear 1002 on one side to rotate. Since it is connected through the workpiece bearing seat 11, the incomplete gear 1002 on the other side is correspondingly meshed with the other set of driving gears 1001 for transmission, so that the workpiece bearing seat 11 drives the workpiece to flip 90 degrees. After the workpiece is fixed, the power is turned on, the servo motor drives the lead screw 9 to rotate, and then drives one end of the pad printing platform 4 to rotate through the nut on its surface, and the other end of the pad printing platform 4 slides on the slide rod through the slider. In order to ensure the accuracy of the equipment, the top of the base 1 is correspondingly pad printed. A position sensor (BRT) is provided in the transmission interval of the platform 4, which can detect the starting position and the end position of the pad printing platform 4, and transmit the electric signal to the external control system, so as to facilitate the control system to adjust its motion state and subsequent process in time. When the pad printing platform 4 approaches the surface of the steel plate mounting area 2, the first cylinder 5 and the second cylinder 8 respectively drive the pad printing rubber head 6 and the scraper 7 to descend. The scraper 7 is attached to the mold surface above the steel plate mounting area 2 under the transmission structure, so as to remove the excess ink on the surface, so that the pad printing rubber head 6 will not absorb too much ink when it is transmitted to this position. After the ink absorption is completed, the pad printing rubber head 6 is transmitted forward again through the transmission structure of the lead screw 9.The pad printing rubber head 6 will be positioned according to the visual sensor (K210) installed at the bottom of the pad printing platform 4 to achieve docking with the workpiece below, and then driven by the second cylinder 8 to descend and contact the workpiece surface to achieve the transfer of printing. After the printed workpiece is removed by the operator, it is placed on one side to dry naturally and uniformly dried. The pad printing rubber head 6 is raised again by the second cylinder 8 and driven by the pad printing platform 4 to contact the mold surface to absorb ink. During the processing, the operator can intermittently add ink to the mold surface, and the equipment can only effectively process monochrome patterns.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
