Description

Technical Field

[0001] The invention relates to the technical field of porcelain printing technology, and more particularly to a porcelain decal device and a method thereof. Background Art

[0002] As a traditional art and daily necessity, porcelain has a long history of production. In the production process of porcelain, decoration is a crucial step, which gives porcelain a unique aesthetic and artistic value. At present, there are two main ways to decorate porcelain: printing and decals.

[0003] Printing is the process of printing patterns on porcelain by means of molds, hand-carving or screen printing. The emergence of screen printing machines has made large-scale decoration of porcelain possible. It can show a more fresh and natural artistic style at the decorative level, which is suitable for large-scale production manufacturers. However, screen printing machines are expensive, have high requirements for equipment and sites, and are complicated to operate. They require professional technicians to operate and maintain them, so they are not suitable for small workshops.

[0004] Decals are made by pre-printing patterns of various colors on paper, and then sticking the patterns to the surface of porcelain with adhesives such as glue to complete the decoration. The decal process is relatively simple and low-cost, suitable for production in small workshops. However, the traditional decal process mainly relies on manual operation, with low production efficiency, and with the continuous increase in labor costs, the cost of manual decals is also gradually increasing. In addition, the quality of manual decals is also difficult to guarantee, and problems such as uneven decals and incomplete patterns are prone to occur, affecting the overall decorative effect of porcelain.

[0005] At present, although there are some automatic decal equipment on the market, most of these equipment are complex in structure, expensive, difficult to operate, and require professional technicians to operate and maintain, which is not suitable for small workshop production. In addition, the decal effect of these equipment is not satisfactory, and there are problems such as loose decals and unclear patterns.

[0006] Therefore, it is necessary to design a porcelain decal equipment and method with simple structure, low cost and easy operation to improve decal efficiency, reduce production cost, ensure decal quality and meet the production needs of small workshops. Summary of the invention

[0067] Embodiment 1:

[0068] See attached Figure 6 In this embodiment, multiple decals are printed together. The decaled part is a bowl structure, which is attached to the outer surface of the bowl. The manipulator mechanism 3 is adsorbed on the inner bottom surface of the bowl for operation. The specific steps are as follows:

[0069] Step S1: adjusting the distance between the elastic stamping head 62 and the cutting knife 63 according to the size of the decal;

[0070] Step S2: According to the size of the porcelain bowl, the position of the robot mechanism 3 is adjusted, and the robot mechanism 3 rotates, and the porcelain bowl is sucked and loaded by the suction cup 31, and moved to below the elastic stamping head 62;

[0071] Step S3: Place the decals arranged in a long strip on the conveyor rack 11, put one end of the decal between the upper and lower rows of clamping wheels 41, and the clamping wheel driving motor 44 drives the clamping wheel 41 to convey the decal to the L-shaped support rod 14;

[0072] Step S4: After the sticker reaches the target position, the clamping wheel 41 stops driving, the steering gear 54 on the connecting rod telescopic mechanism 5 rotates, and the driving rod 53 is controlled to drive the elastic stamping head 62 and the cutting knife 63 to press downward. The elastic stamping head 62 is lower than the cutting knife 63, and the cutting knife 63 touches the decal first. At this time, the spring of the elastic stamping head 62 is compressed to fix the decal, and the driving rod 53 continues to drive the cutting knife 63 to press down, and cooperates with the lower cutting knife 63 to cut out a piece of decal, and the clamping wheel 41 is started to pull out the decal base paper, and the connecting rod telescopic mechanism 5 returns to its position upward;

[0073] Step S5: the robot mechanism 3 rotates the porcelain by an angle, and then continues to repeat the above steps to carry out the next decal. After all the decals of a porcelain bowl are completed, the robot mechanism 3 rotates to unload the porcelain bowl, completing a decal decoration work.

[0074] Embodiment 2:

[0075] See attached Figure 7 In this embodiment, a long strip of decal sticker that does not need to be cut is used. The decaled piece is a cup structure and is attached to the outer surface of the cup. The manipulator mechanism 3 is adsorbed on the inner bottom surface of the cup for operation. The specific steps are as follows:

[0076] Step S1: For the long strip decals that do not need to be cut, the robot mechanism 3 is adjusted 90 degrees around the vertical direction so that the rotation direction of the end of the robot mechanism 3 is consistent with the conveying direction;

[0077] Step S2: Place the long strip of decals on the conveyor rack 11, put one end of the decal between the upper and lower rows of clamping wheels 41, and the clamping wheel driving motor 44 drives the clamping wheel 41 to convey the decal to the L-shaped support rod 14;

[0078] Step S3: After the sticker reaches the target position, the clamping wheel 41 stops driving, the steering gear 54 on the connecting rod telescopic mechanism 5 rotates, and the driving rod 53 is controlled to drive the elastic stamping head 62 to press downward. At this time, the spring of the elastic stamping head 62 is compressed to fix the sticker;

[0079] Step S4: The clamping wheel 41 is started in the opposite direction to the previous one, and the decal base paper is pulled out backwards. At the same time, the manipulator mechanism 3 drives the porcelain cup to rotate in the original transmission direction, so that the long strip decal covers the circumferential surface of the porcelain cup;

[0080] Step S5: After the sticker is completely covered, that is, the base paper is completely pulled out, the clamping wheel 41 stops driving, the manipulator mechanism 3 stops rotating, and the steering gear 54 on the connecting rod telescopic mechanism 5 rotates back to its original position;

[0081] Step S6: The robot mechanism 3 rotates to unload the porcelain cup, completing a long strip of decal decoration.

[0082] Embodiment 2:

[0083] See attached Figure 8 In this embodiment, a circular decal sticker that does not need to be cut is used. The decaled piece is a bowl structure and is attached to the inner edge of the bowl. The manipulator mechanism 3 is adsorbed on the outer bottom surface of the bowl for operation. The specific steps are as follows:

[0084] Step S1: For the circular decals that do not need to be cut, adjust the spacing between the two rows of clamping wheels 41, and replace the cutting knife 63 with another identical elastic stamping head 62, and replace the circular sponge;

[0085] Step S2: Put the annular decal sticker on the conveying rack 11, put one end of the sticker between the upper and lower rows of clamping wheels 41, and the clamping wheel driving motor 44 drives the clamping wheel 41 to convey the sticker to the L-shaped support rod 14;

[0086] Step S3: After the sticker reaches the target position, the clamping wheel 41 stops driving, the steering gear 54 on the connecting rod telescopic mechanism 5 rotates, and the driving rod 53 is controlled to drive the elastic stamping head 62 to press downward. At this time, the springs at both ends are compressed to fix the sticker at the front and rear ends respectively;

[0087] Step S4: the clamping wheel 41 is started to pull out the decal backing paper, and at the same time, the elastic stamping head 62 keeps pressing;

[0088] Step S5: After the bottom paper is completely pulled out, the clamping wheel 41 stops driving, and the steering gear 54 on the connecting rod telescopic mechanism 5 rotates back to its original position;

[0089] Step S6: The robot mechanism 3 rotates to unload the porcelain bowl, completing a circular decal decoration work.

[0090] The working principle of the porcelain decal equipment of the above-mentioned embodiments is as follows: according to the size of the decal, the distance between the elastic stamping head 62 and the cutting knife 63 is adjusted. Since the end of the elastic stamping head 62 is loaded with sponge, which is a flexible material, it can adapt to the curved surface shape of the porcelain and protect the decal. The control module controls the clamping wheel 41 to transmit the decal according to the operation requirements. After reaching the specified position, the servo 54 controls the stamping mechanism 6 to press down. After completing the cutting of the decal, the servo 54 controls the stamping mechanism 6 to rise.

[0091] The porcelain decal device of the present invention realizes pressing and shearing through the up and down movement of a stamping mechanism 6, simulating the manual decal process, and has simple functions. Compared with large equipment such as a silk screen printer, it has a simple structure and low mechanical cost, and is suitable for production and processing in small workshops.
