Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a printing structure with adjustable UV ink printing thickness. Background Technology

[0002] UV ink, or ultraviolet light curing ink, refers to ink that uses ultraviolet light of different wavelengths and energies to polymerize monomers in the ink binder into polymers, thereby forming an ink film and drying it. It has many advantages such as fast drying speed, high gloss, color stability, environmental friendliness, and strong abrasion resistance.

[0003] Currently, when using UV inks for screen printing, the distance between the printing screen and the worktable is fixed, making it impossible to flexibly change the printing thickness according to different printing needs. Furthermore, the stability of manually moving the squeegee is poor, which can easily lead to uneven printing patterns, blurred edges, and other problems, resulting in uneven printing thickness. To address these issues, we propose a printing structure with adjustable UV ink printing thickness. Utility Model Content

[0004] The purpose of this invention is to provide a printing structure with adjustable UV ink printing thickness to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A printing structure for adjustable UV ink printing thickness includes a worktable. A bearing is embedded in the upper surface of the worktable, and a threaded rod is fixedly connected to the inner ring of the bearing. A motor is fixedly connected to the bottom surface of the worktable, and the output end of the motor is fixedly connected to the bottom surface of the threaded rod. A lifting platform is threadedly connected to the outer surface of the threaded rod. A printing screen is fixedly connected to the bottom surface of the lifting platform. Two first guide rods are fixedly connected to the outer surface of the lifting platform. A connecting block is slidably connected to the outer surfaces of the two first guide rods. Two sliding cylinders are fixedly connected to the bottom surface of the connecting block. A connecting rod is slidably connected to the inner sidewall of each sliding cylinder. A doctor blade is fixedly connected to the bottom surface of each connecting rod. A distance sensor is fixedly connected to the bottom surface of the lifting platform. An extrusion mechanism is fixedly connected to the upper surface of the doctor blade.

[0007] In a further embodiment, the extrusion mechanism includes two elastic elements, and the upper surface of the connecting block has three first connecting holes.

[0008] In a further embodiment, the inner walls of both first connecting holes are slidably connected to second optical rods, and the bottom surfaces of the two second optical rods are jointly fixedly connected to an extrusion plate.

[0009] In a further embodiment, a threaded fixing rod is fixedly connected to the upper surface of the extrusion plate, a fixing nut is threadedly connected to the outer surface of the threaded fixing rod, and a fixing frame is fixedly connected to the upper surface of the connecting block.

[0010] In a further embodiment, an electric push rod is fixedly connected to the bottom surface of the workbench, and two second connection holes are provided on the bottom surface of the workbench.

[0011] In a further embodiment, the inner walls of the two second connecting holes are slidably connected to a pressing frame, the output end of the electric push rod is fixedly connected to the outer surface of the pressing frame, and two elastic pads are fixedly connected to the outer surface of the pressing frame.

[0012] In a further embodiment, the upper surface of the printing screen is provided with multiple return grooves, and the upper surface of the worktable is fixedly connected with multiple third optical rods, each of which is slidably connected to the lifting platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device uses a motor to drive a threaded rod to rotate, which in turn raises and lowers the lifting platform and printing screen. Combined with a distance sensor to detect the height, it allows for adjustment of the distance between the printing screen and the worktable according to printing needs. This enables flexible control of the UV ink printing thickness. By adjusting the threaded fixing rod and fixing nut, the squeezing force of the elastic element on the squeegee can be changed, making the squeegee's effect on the ink controllable and stable. This avoids inconsistent printing thickness caused by uneven squeegee pressure, thus improving printing quality. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 In this utility model, a printing structure for adjustable UV ink printing thickness includes a worktable 1. A bearing 2 is embedded in the upper surface of the worktable 1. A threaded rod 3 is fixedly connected to the inner ring of the bearing 2. A motor 4 is fixedly connected to the bottom surface of the worktable 1. The output end of the motor 4 is fixedly connected to the bottom surface of the threaded rod 3. A lifting platform 5 is threadedly connected to the outer surface of the threaded rod 3. A printing screen 6 is fixedly connected to the bottom surface of the lifting platform 5. Two first guide rods 7 are fixedly connected to the outer surface of the lifting platform 5. The outer surfaces of the two first guide rods 7 are slidably connected together. The connecting block 8 has two sliding cylinders 9 fixedly connected to its bottom surface. Each sliding cylinder 9 has a connecting rod 10 slidably connected to its inner side wall. Each connecting rod 10 has a scraper 11 fixedly connected to its bottom surface. The lifting platform 5 has a distance sensor 12 fixedly connected to its bottom surface. The scraper 11 has an extrusion mechanism 13 fixedly connected to its upper surface. The motor 4 drives the threaded rod 3 to rotate, which enables the lifting platform 5 and the printing screen 6 to move up and down. With the distance sensor 12 detecting the distance, the height of the printing screen 6 can be precisely controlled, thereby changing the printing thickness.

[0023] The extrusion mechanism 13 includes two elastic elements 1301. The upper surface of the connecting block 8 has three first connecting holes 1302. The inner walls of two of the first connecting holes 1302 are slidably connected to second guide rods 1303. The bottom surfaces of the two second guide rods 1303 are fixedly connected to an extrusion plate 1304. The upper surface of the extrusion plate 1304 is fixedly connected to a threaded fixing rod 1305. The outer surface of the threaded fixing rod 1305 is threadedly connected to a fixing nut 1306. The upper surface of the connecting block 8 is fixedly connected to a fixing frame 1307. By changing the height of the extrusion plate 1304, the elastic elements 1301 can be extruded, making the extrusion plate 1304 more evenly stressed and reducing the inconsistent printing thickness caused by uneven pressure on the scraper 11.

[0024] An electric push rod 14 is fixedly connected to the bottom surface of the worktable 1. Two second connection holes 16 are opened on the bottom surface of the worktable 1. A pressing frame 15 is slidably connected to the inner wall of the two second connection holes 16. The output end of the electric push rod 14 is fixedly connected to the outer surface of the pressing frame 15. Two elastic pads 17 are fixedly connected to the outer surface of the pressing frame 15. Multiple return grooves 18 are opened on the upper surface of the printing screen 6. Multiple third light rods 19 are fixedly connected to the upper surface of the worktable 1. Each third light rod 19 is slidably connected to the lifting platform 5. The pressing frame 15 is moved downward by the electric push rod 14, which can fix the printing material and prevent it from shifting during the printing process.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the motor 4 drives the threaded rod 3 to rotate, which in turn moves the lifting platform 5 and the printing screen 6 upward. The electric push rod 14 retracts to lift the pressing frame 15 upward, placing the material onto the worktable 1. The pressing frame 15 is then moved downward to press and fix the printing material. The lifting platform 5 is also moved downward, and the distance sensor 12 detects the distance from the worktable 1. The height of the lifting platform 5 and the printing screen 6 is adjusted according to the required printing thickness. The threaded fixing rod 1305 is moved downward to squeeze the elastic element 1301 and the squeegee 11. The fixing nut 1306 is brought close to the fixing frame 1307 to fix the position of the threaded fixing rod 1305. UV ink is poured into the printing screen 6, and the connecting block 8 and the squeegee 11 are moved to print. Finally, ultraviolet light is used to fix the ink.
