[0001] The utility model relates to the technical field of pad printing equipment, in particular to a pad printing equipment. Background Art

[0002] Pad printing is the process of transferring the pattern engraved on the steel plate to the workpiece through the action of the pad printing rubber head. After the pad printing rubber head comes into contact with the pattern, the pad printing rubber head is dipped with ink of the corresponding pattern. After the pad printing rubber head is covered on the workpiece, the pad printing is completed, which is similar to stamping in daily work.

[0024] Pad printing is the process of transferring the pattern engraved on the steel plate to the workpiece through the action of the pad printing rubber head. After the pad printing rubber head comes into contact with the pattern, the pad printing rubber head is dipped with ink of the corresponding pattern. After the pad printing rubber head is covered on the workpiece, the pad printing is completed, which is similar to stamping in daily work.

[0025] Because different inks have different display effects, some inks need to be left in the air for a period of time before they can come into contact with the product after coming into contact with the pad printing rubber head; and the ink on the pad printing rubber head needs to be wiped off after printing, otherwise it will affect the subsequent printing. The current traditional practice is to separate the drying and wiping steps, which is inefficient, and the drying and wiping structures are separate, occupying a large volume, affecting the miniaturization design of pad printing equipment.

[0026] In order to solve the above problems, this embodiment discloses a pad printing device, the structure of which is as follows: Figures 1 to 3As shown, the pad printing equipment includes a frame 100, an ink dipping mechanism 101, an ink drying and wiping mechanism 200, and a placing jig 104 which are sequentially installed from one end of the frame 100 to the other end, and a pad printing transverse shift driving mechanism 105 located above the ink dipping mechanism 101, the ink drying and wiping mechanism 200 and the placing jig 104, and a pad printing rubber head 106 is installed at the output end of the pad printing transverse shift driving mechanism 105; the ink dipping mechanism 101 is used for dipping the pad printing rubber head 106 in ink, the ink drying and wiping mechanism 200 is used for wiping and drying the pad printing rubber head 106, the placing jig 104 is used for placing products to be pad printed, and the pad printing transverse shift driving mechanism 105 is used for driving the pad printing rubber head 106 to move horizontally and rise and fall.

[0027] In this embodiment, the pad printing transverse driving mechanism 105 is preferably a servo system composed of three axes of x, y, and z, which can provide more precise control over the pad printing rubber head 106; the pad printing transverse driving mechanism 105 drives the pad printing rubber head 106 to dip ink on the ink dipping mechanism 101, wipe or dry the ink on the ink drying and wiping mechanism 200, and print the product on the placement jig 104; in addition, the structures and principles of the ink dipping mechanism 101 and the placement jig 104 in this embodiment are all existing technologies and will not be repeated here.

[0028] Furthermore, the ink drying and wiping mechanism 200 includes a wiping plate 201, a film supplying mechanism 202 installed on the frame 100, a wiping transverse driving mechanism 102 and an oven 103 with an opening at the upper end; the wiping plate 201 is located above the opening of the oven 103, the wiping transverse driving mechanism 102 is used to drive the wiping plate 201 and the film supplying mechanism 202 to move transversely at the same time to expose or cover the opening of the oven 103, the film supplying mechanism 202 is located on one side of the wiping plate 201, and the film of the film supplying mechanism 202 is wrapped around the other side of the wiping plate 201.

[0029] In this embodiment, the wiping transverse drive mechanism 102 is preferably a cylinder; the feeding drive mechanism 207 is preferably a synchronous drive structure composed of a motor, a synchronous belt, and a synchronous wheel.

[0030] In actual use, the pad printing transverse driving mechanism 105 drives the pad printing rubber head 106 to dip ink from the ink dipping mechanism 101; then the wiping transverse driving mechanism 102 drives the wiping plate 201 to move away to expose the opening of the oven 103, and at the same time the pad printing rubber head 106 extends from the opening into the oven 103 to dry the ink; then the pad printing rubber head 106 moves to the placement fixture 104 for pad printing, and at the same time the wiping plate 201 is reset to avoid excessive heat loss in the oven 103. Preferably, the size of the wiping plate 201 is adapted to the size of the opening of the oven 103; after printing is completed, the pad printing rubber head 106 contacts the film on the upper end surface of the wiping plate 201 for wiping, and finally returns to the ink dipping mechanism 101 for the next round of printing.

[0031] In addition, a heat dissipation fan 208 is installed at the lower end of the oven 103, which can discharge the heat in the oven 103 in time when the oven 103 needs to be maintained, thereby improving the maintenance efficiency.

The clean film is wound on the feeding roller 203, and is interspersed on the tension rollers 205 to keep the film tight, while the wiped film is wound and stored on the feeding roller 204, and the feeding drive mechanism 207 drives the feeding roller 204 to rotate so as to automatically rewind the film. Preferably, a rubber roller 206 is provided on the other side of the wiping plate 201 to ensure the smoothness of film rewinding.

[0033] In summary, a pad printing device of the present embodiment is provided with an ink dipping mechanism 101, an ink drying and wiping mechanism 200, a placing jig 104 in sequence from one end to the other end of a frame 100, and a pad printing transverse driving mechanism 105 located above the ink dipping mechanism 101, the ink drying and wiping mechanism 200 and the placing jig 104. The ink drying and wiping mechanism 200 can wipe and dry at the same time, which saves space and improves efficiency.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
