Screen printing shows high flexibility and adaptability in bottle body printing, can handle complex patterns and multiple colors, and meet diverse market demands.

[0003] However, applying screen printing to bottle body printing still faces many challenges and difficulties. Different surface shapes of the bottles to be printed easily lead to uneven ink distribution when the ink on the screen plate is transferred to the bottle body. Especially at the corners and depressions of the bottle body, printing defects such as ink accumulation or missing are likely to occur, affecting the printing quality. Therefore, a high-precision positioning and clamping mechanism is crucial for ensuring the accurate position of the pattern, but the accuracy of existing equipment is still insufficient, which easily leads to pattern deviation or deformation.

[0004] In summary, how to ensure the printing quality on the bottle body surface is an urgent problem to be solved. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the defects of the above-mentioned existing technologies and provide a clamping structure for bottle body printing and a bottle body printing device with this structure, so as to solve or partially solve the problem of printing defects that are likely to occur when the surface shape of the bottle body is irregular.

[0037] Embodiment 1

[0038] In view of the problems existing in the foregoing prior art, this embodiment provides a bottle body printing clamping structure, including:

[0039] A movable block 1 and an arc-shaped slide rail 2 movably connected thereto. The movable block 1 can slide along the arc-shaped slide rail 2. The two end portions of the arc-shaped slide rail 2 are respectively connected with a fixed seat 3 and a telescopic member. The arc-shaped slide rail 2 is obtained by dividing a complete circular slide rail with a straight line. The movable block 1 is fixedly connected to the printing device body.

[0040] Specifically, the telescopic member includes a cylinder body 4 and a guide rod 5 matching the cylinder body 4. The guide rod 5 is connected with a fixed head 6 facing the fixed seat 3. The fixed seat 3 and the fixed head 6 cooperate to clamp the bottle body during the printing process. The telescopic member further includes a first quick-release plate 7 connected to the cylinder body 4. The first quick-release plate 7 is matched and connected with a first groove 8 opened at the end of the arc-shaped slide rail 2. The first quick-release plate 7 is provided with a first waist-shaped groove 9, and the first quick-release plate 7 is threadedly connected with the arc-shaped slide rail 2.

[0041] The fixed seat 3 is matched and connected with a second groove 11 opened at the end of the arc-shaped slide rail 2 through a second quick-release plate 10. The second quick-release plate 10 is provided with a second waist-shaped groove 12, and the second quick-release plate 10 is threadedly connected with the arc-shaped slide rail 2. A chute 13 is provided in the circumferential direction of the arc-shaped slide rail 2.

[0042] Preferably, there is a self-locking mechanism between the movable block 1 and the arc-shaped slide rail 2, which will be locked after reaching the position, ensuring that the angle between the connection line between the two end portions of the arc-shaped slide rail 2 and the horizontal plane is relatively fixed during the printing operation process.

[0043] In this embodiment, the cross-sections of the first groove 8 and the second groove 11 are trapezoidal to achieve quick disassembly of the fixing base 3 and the telescopic member.

[0044] Furthermore, sliding grooves 13 are respectively provided on the inner side and the outer side of the arc-shaped slide rail 2 in this embodiment to ensure the stability of the arc-shaped slide rail 2 during movement.

[0045] In this embodiment, the telescopic member is realized by a commercially available electric cylinder or air cylinder, and the movable block 1 and the arc-shaped slide rail 2 are commercially available products.

[0046] The working principle of this structure is as follows: Taking a prism-shaped bottle body as an example, before the formal printing operation, the movable block 1 and the arc-shaped slide rail 2 are adjusted according to the surface angle of the bottle body to be printed. Since the movable block 1 is fixedly connected to the printing device, the movable block 1 is fixed relative to the printing device, and the arc-shaped slide rail 2 will rotate, thereby changing the angle between the line connecting the two ends of the arc-shaped slide rail 2 and the horizontal plane. After reaching the position, the relative fixation between the movable block 1 and the arc-shaped slide rail 2 is maintained. At this time, the bottle body printing clamping structure is as Figure 3 shown. By adjusting the telescopic member, the bottle body to be printed is limited between the fixing base 3 and the fixing head 6 in a way of being fixed by the central axis, and then the formal printing operation is carried out. Preferably, during the printing operation, the relative position between the arc-shaped slide rail 2 and the movable block 1 can be finely adjusted to further ensure the printing quality, which can be realized by an existing computer program. By adjusting the angle, the surface of the bottle body is fully contacted with the screen plate during printing, thereby ensuring the printing quality.

[0047] Embodiment 2

[0048] On the basis of Embodiment 1, referring to Figure 2 , this embodiment provides a bottle body printing device, which includes the bottle body printing clamping structure described in Embodiment 1. In addition, it further includes: a first slide table 14 arranged along the X direction, and a second slide table 15 and a third slide table 18 connected to the first slide table 14 and arranged along the Y direction. Among them, the second slide table 15 is connected to a squeegee 17 through a telescopic structure 16, the third slide table 18 is connected with a screen plate 19, and the fixing base 3 and the fixing head 6 are located below the screen plate 19. It should be noted that the sizes of the parts of the fixing base 3 and the fixing head 6 in contact with the bottle body to be printed need to be adjusted in advance according to actual needs to ensure that the printing operation of the screen plate 19 will not be affected.

[0049] In this embodiment, the telescopic structure 16 is realized by a commercially available electric cylinder or air cylinder.

[0050] The working principle of the bottle body printing device is: Using the bottle body printing clamping structure to adjust the angle between the line connecting the two ends of the arc-shaped slide rail 2 and the horizontal plane. At this time, the bottle body printing device is as Figure 4As shown below. Next, the following printing operations are performed:

[0051] First position: Under the action of the telescopic structure, the squeegee 17 and the screen plate 19 are separated from each other. A bottle to be printed (not shown in the figure) is arranged and fixed below the screen plate 19. At this time, the bottle and the screen plate 19 are separated from each other. Ink is pre-set on the screen plate 19. The bottle to be printed is fixed in a way that ensures its central axis is stationary. After the bottle and the screen plate 19 come into contact, the movement of the screen plate 19 can drive the bottle to rotate to complete the printing.

[0052] Second position: Under the action of the first sliding table 14, the squeegee 17 and the screen plate 19 are moved downward as a whole until the screen plate 19 comes into contact with the starting position of the bottle to be printed. Under the action of the telescopic structure 16, the squeegee 17 and the screen plate 19 come into contact with each other.

[0053] Third position: Under the cooperation of the second sliding table 15 and the third sliding table 18, while the squeegee 17 remains in contact with the screen plate 19 and the screen plate 19 is in contact with the bottle to be printed, the squeegee 17 is moved on the screen plate 19. The ink is pressed into the holes of the screen plate by the squeegee and transferred to the surface of the bottle, realizing the fine printing of patterns and words.

[0054] Fourth position: Under the action of the telescopic structure 16, the squeegee 17 and the screen plate 19 are separated from each other. Under the action of the first sliding table 14, the screen plate 19 and the bottle to be printed are separated from each other. Under the cooperation of the second sliding table 15 and the third sliding table 18, the squeegee 17 and the screen plate 19 return to the first position, completing one round of printing.

[0055] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention.
