detailed description

Below in conjunction with accompanying drawing 1 to accompanying drawing 6 the utility model is described in detail.

A spherical automatic screen printing equipment of the present utility model comprises a workbench 4, the workbench 4 is connected with a lifting seat 1 and a power device 5 for driving the lifting seat 1, and the lifting seat 1 is provided with a The first clamping mechanism 6 and the second clamping mechanism 7 of screen frame, the first clamping mechanism 6 and the second clamping mechanism 7 are identical with the clamping mechanism that existing screen printing is used for clamping printing screen frame, Not described in detail here, the lifting base 1 is also connected with a traversing track 11 and a base 12 sliding along the traversing track 11, and the base 12 is connected with a longitudinal sliding plate 13 that slides longitudinally and a first drive for driving the longitudinal sliding plate. Cylinder 14, said longitudinal slide plate 13 is connected with scraper mechanism 15; also includes traversing drive mechanism 2, transverse arc track 3 and guide seat 16 sliding along transverse arc track 3, said guide seat 16 and longitudinal slide plate 13 are movable connected, the lateral drive mechanism drives the base 12 to move laterally; when the device is in operation, the lateral drive mechanism drives the base 12 to slide horizontally along the traverse track 11. Since the longitudinal sliding plate 13 and the base 12 are longitudinally slidably connected, Therefore, when the guide seat 16 slides along the transverse arc track 3, since the power device drives the longitudinal slide plate 13 to automatically slide along the arc section of the transverse arc track 3, since the guide seat 16 is flexibly connected to the longitudinal slide plate 13, Therefore, the guide seat 16 can realize self-rotation according to the guidance of the transverse arc track 3, and the longitudinal sliding plate 13 automatically slides longitudinally downward along the base 12 so that the scraper mechanism 15 can realize a sliding track along the arc surface to realize a spherical surface. After the screen printing operation is completed, the first cylinder 14 lifts the longitudinal slide 13, so that the longitudinal slide 13 moves in an arc next time after being reset; and the guide seat 16 moves in a straight line before entering the arc. Therefore, it can also use the linear motion as flat printing to realize simultaneous printing of flat and spherical surfaces. It can be seen from this that this equipment can not only print on flat and spherical surfaces at the same time, but also reduce printing processes and save costs. The way of making the scraper mechanism move along the spherical surface can improve the printing quality of the printing screen on the spherical surface.

In order to make the guide seat 16 slide more smoothly, the guide seat 16 includes a seat plate 161 and at least two guide pulleys 162 arranged on the seat plate 161 , and the guide pulleys 162 slide along the transverse arc track 3 . Two guide pulleys 162 can be respectively arranged on the left end and the right end of the guide seat 16, which can increase the balance force and make the guide seat 16 slide more stably.

During work, the scraper holder 153 is mainly controlled by the second cylinder 152, so that the scraper installed on the scraper holder 153 contacts the printing screen, that is, the second cylinder 152 controls the lifting of the scraper holder 153, so that the scraper and the printing screen are separated or separated. contact action.

Specifically, the scraper frame 153 includes an upper connecting plate 154, a lower connecting plate 155 and a guide column 156, the upper connecting plate 154 is connected with the lower connecting plate 155 through the guiding column 156, and the lower connecting plate 155 is provided with a The assembly head 157 of the scraper is installed, the second cylinder 152 is fixedly connected with the scraper arm 151 , the piston rod of the second cylinder 152 is connected with a bolt 158 , and the bolt 158 passes through the upper connecting plate 154 and is connected with an adjustable nut 159 . The most important thing in this solution is to use the screw connection length of the adjustable nut 159 and the bolt 158, so that the lifting stroke of the entire scraper can be adjusted, which is more versatile and practical for printing to adapt to different products.

And in order to improve the quality of printing, described scraper frame 153 is provided with two groups. The two sets of scraper holders 153 are equipped with scrapers, and there is an ink return gap between the two scrapers, so that when the scraper scrapes back and forth, ink will always be kept in the ink return gap, avoiding unclear printing caused by ink accumulation and other quality issues.

The servo motor 21 can control the movement and positioning of the base 12 more precisely by utilizing the transmission mode of the synchronous wheel and the synchronous belt 24 , thereby providing more precise printing accuracy.

In this technical solution, the transverse arc track 3 includes a first horizontal track 31 , an arc track 32 and a second horizontal track 33 connected in sequence. The radius and chord length of the arc rail 32 correspond to the surface of the product to be printed, so that the direction of the scraper mechanism 15 is consistent with the surface of the product. While the movement of the first horizontal rail 31 and the second horizontal rail 33 is the same as that of the prior art, the key point of this solution is to combine flat printing and spherical printing to realize the completion of one printing operation.

According to the difference of the printed surface of the product, the arc track 32 is an inner concave track or an outer convex track. When the inner concave spherical surface needs to be printed, the inner concave track is used; when the outer convex spherical surface needs to be printed, the outer convex track is used.
