Description

Technical Field

[0001] This utility model relates to the field of screen printing device technology, and more specifically, to a photocurable follow-up screen printing device. Background Technology

[0002] In existing bottle screen printing processes, automatic screen printing machines are typically used to print graphics on the bottle surface. To improve production efficiency and ink adhesion, the ink needs to be cured immediately after printing, commonly using ultraviolet (UV) curing. Currently, most screen printing equipment is equipped with UV curing devices that are fixedly installed at a specific location on the screen printing machine, such as above the conveyor belt or near the screen printing platform.

[0003] In actual operation, after screen printing, the bottle needs to be moved to the UV curing unit for curing via a conveying or rotating mechanism. Because the bottle needs a certain time or distance to reach the curing station after screen printing, the curing response is delayed, increasing the risk of leveling and misalignment of the ink in the uncured state. This is especially problematic for products requiring high precision or 3D printing, easily affecting the final print quality. Furthermore, existing bottles are typically clamped and fixed horizontally, but conical bottles have sloping (conical) sidewalls. Screen printing with conical bottles horizontally can lead to poor contact, uneven pressure, and poor ink scraping angles, ultimately resulting in serious printing quality problems such as incomplete, blurry, distorted, inaccurate positioning, and uneven ink distribution. Utility Model Content

[0004] The purpose of this invention is to provide a light-curing follow-up screen printing device, which can quickly cure after screen printing, improve the quality and production efficiency of screen-printed products, and can also meet the screen printing needs of different bottles, thus enhancing the practicality of the device.

[0005] This utility model is achieved through the following technical solution:

[0006] A photocurable screen printing device includes a worktable with a turntable on its surface. A screen printing mechanism is arranged counter-clockwise on the outer side of the turntable. A clamping mechanism is arranged in a circular array on the surface of the turntable, with the screen printing mechanism located above the clamping mechanism. The clamping mechanism includes a connecting seat, a fixed seat, and a clamping seat. One end of the connecting seat is fixedly connected to the turntable, and the other end is fixedly connected to the fixed seat. The clamping seat is rotatably connected to the fixed seat, and the side wall of the fixed seat is provided with a photocurable mechanism.

[0007] Furthermore, the screen printing mechanism includes a fixing frame, a printing plate assembly slidably connected to the fixing frame, and a printing assembly disposed above the printing plate assembly and fixedly connected to the fixing frame.

[0008] Furthermore, the printing plate assembly is driven by a servo motor.

[0009] Furthermore, the light-curing mechanism includes a support plate connected to the fixed base and an ultraviolet lamp fixed to the support plate.

[0010] Furthermore, the ultraviolet lamp is tilted, the clamping base in the light-curing state is parallel to the ultraviolet lamp, and the clamping base in the printing state forms an angle with the ultraviolet lamp.

[0011] Furthermore, the clamping seat includes a mounting block, a fixed clamping part, and a movable clamping part. The mounting block is installed in the cavity of the fixed seat via a rotating shaft. A horizontal plate is fixedly connected to the lower part of the mounting block, and a guide plate is provided at the front end of the horizontal plate. The fixed clamping part is connected to the mounting block, and the movable clamping part is connected to the guide plate. The central axis of the fixed clamping part and the central axis of the movable clamping part coincide.

[0012] Furthermore, the fixed clamping part includes a support column, a tubular motor is provided inside the support column, the output end of the tubular motor is connected to a clamping block, and the working surface of the clamping block is provided with a groove; the movable clamping part includes a frame, sliders are provided on both sides of the lower part of the frame, the two sliders are respectively slidably connected to the guide plate, a clamping column is provided on the top of the frame, and a rubber head is provided on the working surface of the clamping column.

[0013] Furthermore, a cylinder is provided at the bottom of the horizontal plate, and the driving end of the cylinder is fixedly connected to the slider. Slide grooves are provided on both sides of the guide plate, and the two sliders are slidably installed in the slide grooves respectively.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0015] In this invention, the clamping base, fixing base, curing mechanism, and connecting base work together to allow the curing mechanism to rotate with the clamping base, thus enabling rapid curing after screen printing on the bottle and avoiding delays in curing response that could affect printing quality. The rotatable connection between the clamping base and the fixing base allows for adjustment of the clamping base's angle, thereby adjusting the angle of the bottle. This ensures that the entire area (or its main portion) of the bottle to be printed is a relatively flat surface parallel to and in close contact with the screen, meeting the requirements for printing on conical bottles and enhancing the practicality of the device.

[0029] Example 1

[0030] Reference Figures 1-6 This embodiment provides a photocuring screen printing device, including a worktable 1. The worktable 1 has a turntable 2 on its surface. The turntable 2 has screen printing mechanisms 5 distributed counterclockwise on its outer side. The surface of the turntable 2 has clamping mechanisms 3 arranged in a circular array. The screen printing mechanisms 5 are located above the clamping mechanisms 3. The clamping mechanism 3 includes a connecting seat 31, a fixing seat 32, and a clamping seat 33. One end of the connecting seat 31 is fixedly connected to the turntable 2, and the other end of the connecting seat 31 is fixedly connected to the fixing seat 32. The clamping seat 33 is rotatably connected to the fixing seat 32. The side wall of the fixing seat 32 is provided with a photocuring mechanism 4.

[0031] The clamping base 33, the fixing base 32, the curing mechanism 4, and the connecting base 31 work together to allow the curing mechanism 4 to rotate with the clamping base 33, thus enabling rapid curing after screen printing on the bottle and avoiding lag in curing response that could affect printing quality. The clamping base 33 is rotatably connected to the fixing base 32, allowing adjustment of the angle of the clamping base 33 to adjust the angle of the bottle. This ensures that the entire area (or its main part) of the bottle to be printed is parallel to and in close contact with the screen as a relatively flat surface, suitable for printing on conical bottles and improving the practicality of the device. Both the turntable 2 and the clamping base 33 are driven by servo motors, and the connecting base 31 is fixed to the turntable 2 with bolts.

[0032] In a preferred embodiment, the screen printing mechanism 5 includes a fixing frame 51, a printing plate assembly 52 slidably connected to the fixing frame 51, and a printing assembly 53 disposed above the printing plate assembly 52 and fixedly connected to the fixing frame 51. The screen printing mechanism 5 can be a two-color screen printing machine for glass bottles (e.g., Dongguan Xinze Printing Machinery Co., Ltd., XZ-P60-108). Alternatively, the screen printing mechanism 5 can be a multi-color screen printing machine, such as an 8-color machine, which can perform photocuring after printing, and then perform the next printing cycle, achieving multiple printings and improving printing efficiency.

[0033] In a preferred embodiment, the printing plate assembly 52 is driven by a servo motor. During use, the squeegee of the printing assembly 53 contacts the screen printing plate of the printing plate assembly 52, and the servo motor drives the screen printing plate to move, causing the squeegee to evenly scrape across the screen printing plate, thus achieving bottle printing.

[0034] In a preferred embodiment, the light-curing mechanism 4 includes a support plate 41 connected to the fixing base 32 and an ultraviolet lamp 42 fixed to the support plate 41. The support plate 41 and the fixing base 32, as well as the support plate 41 and the ultraviolet lamp 42, are all connected by screws.

[0035] In a preferred embodiment, the ultraviolet lamp 42 is tilted, the clamping seat 33 in the light-curing state is parallel to the ultraviolet lamp 42, and the clamping seat 33 in the printing state forms an angle with the ultraviolet lamp 42.

[0036] In a preferred embodiment, the clamping base 33 includes a mounting block 3301, a fixed clamping part, and a movable clamping part. The mounting block 3301 is mounted in the cavity of the fixed base 32 via a rotating shaft. A horizontal plate 3306 is fixedly connected to the lower part of the mounting block 3301. A guide plate 3307 is provided at the front end of the horizontal plate 3306. The fixed clamping part is connected to the mounting block 3301, and the movable clamping part is connected to the guide plate 3307. The central axis of the fixed clamping part and the central axis of the movable clamping part coincide.

[0037] In a preferred embodiment, the fixed clamping part includes a support column 3302, within which a tubular motor 3303 is housed. The output end of the tubular motor 3303 is connected to a clamping block 3304, the working surface of which has a groove 3305. The movable clamping part includes a frame 3309, with sliders 3310 on both sides of the lower part of the frame 3309. The two sliders 3310 are slidably connected to the guide plate 3307. A clamping column 3311 is located at the top of the frame 3309, and the working surface of the clamping column 3311 has a rubber head 3312. The support column 3302 is welded to or screwed to the mounting block 3301. The tubular motor 3303 is a servo motor, and the clamping column 3311 is connected to the frame 3309 via bearings to achieve rotation of the clamping column 3311. In use, the bottom of the bottle is located in the groove 3305, and the bottle mouth is pressed against the rubber head 3312 to clamp and fix the bottle. The tubular motor 3303 drives the clamping block 3304 to rotate, thereby driving the bottle to rotate and realize printing on the bottle body.

[0038] In a preferred embodiment, a cylinder 3313 is provided at the bottom of the horizontal plate 3306. The driving end of the cylinder 3313 is fixedly connected to the slider 3310. Slide grooves 3308 are provided on both sides of the guide plate 3307, and the two sliders 3310 are slidably installed in the slide grooves 3308 respectively. The cylinder 3313 drives the sliders 3310 to move within the slide grooves 3308, causing the clamping column 3311 at the top of the frame 3309 to move, thereby adjusting the distance between the clamping column 3311 and the clamping block 3304 to accommodate the clamping and fixing of bottles of different lengths.

[0039] The working principle of a light-curing screen printing device is as follows: The bottom of the bottle is placed in the groove 3305 of the clamping block 3304. The cylinder 3313 drives the slider 3310 at the bottom of the frame 3309 to move, thereby bringing the clamping post 3311 at the top of the frame 3309 closer to the bottle until the rubber head 3312 on the clamping post 3311 abuts against the bottle mouth, thus clamping and fixing the bottle. The servo motor drives the turntable 2 to move, allowing the bottle to rotate with the turntable 2. When the bottle is below the screen printing mechanism 5, the bottle is adjusted so that the bottle wall is horizontal or nearly horizontal with the screen printing plate. While the tubular motor 3303 drives the bottle to rotate, the screen printing mechanism 5 performs screen printing (i.e., the servo motor drives the screen printing plate to move so that the squeegee evenly scrapes across the screen printing plate to achieve printing on the bottle). After printing, the bottle is adjusted to be parallel with the ultraviolet lamp 42, and the bottle is driven to rotate for light curing.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
