Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing device technology, specifically to a glass surface printing device with a dust extraction mechanism. Background Technology
[0002] Glass surface printing is a process that uses digital printing technology to print patterns and designs onto the glass surface, enhancing its decorative properties. It typically employs UV printing technology or digital color enamel glass printing technology to form a printed layer on the glass material surface.
[0003] Most glass surface printing devices currently on the market are similar in overall structure, consisting of a printing section and a carrier section. The carrier section is generally based on a conveyor belt, which transports the glass sheet to the area below the printing section. The printing section is a combination of a servo drive module and a UV printing nozzle. The servo drive module drives the printing nozzle to reciprocate, which can accurately print various patterns. However, there are some functional deficiencies in actual use, and there is room for improvement. For example, if there are fibers or dust on the glass surface before printing, they will be covered under the ink during printing, causing problems such as pattern deformation, blurring, and easy peeling. It also lacks the function of cleaning foreign objects and dust from the glass surface.
[0004] Now, a novel glass surface printing device with a dust extraction mechanism is proposed to solve the above problems. Utility Model Content

[0009] As a further technical solution of this utility model, the rear end of the air knife is connected to the front end of the high-pressure air pump interface, and the high-pressure air pump interface and the interior of the air knife are connected.
[0010] As a further technical solution of this utility model, the bottom ends of the air inlet and the air knife are flush, and the bottom end of the air inlet is higher than the top end of the conveyor belt.
[0011] As a further technical solution of this utility model, a concave frame is fixedly connected to the right side of the concave cover, a laser ranging sensor is installed at the middle position of the top of the concave frame, two sets of first electric cylinders are respectively installed at the front and rear ends of the top of the support frame, limit cylinders are welded to the four corners of the top of the support frame, and limit rods are fixedly connected to the four corners of the bottom of the support plate.

A pressure sensor is installed between the second electric cylinder and the push plate. The second electric cylinder and the pressure sensor are electrically connected. The bottom end of the push plate is higher than the top end of the conveyor belt.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the glass surface printing device with a dust extraction mechanism not only realizes the function of cleaning foreign objects and floating dust on the glass surface, but also realizes the function of adjusting the material height and the function of adjusting the glass position;
[0014] (1) By setting up a concave cover, an industrial vacuum cleaner interface, an air intake, a high-pressure air pump interface and an air knife, when in use, the glass plate is placed horizontally on the conveyor belt, and the conveyor belt transports the glass to the bottom of the UV printing nozzle.

The high-pressure air pump interface 12 and the air knife 13 are internally connected. The bottom ends of the air intake 11 and the air knife 13 are flush. The bottom end of the air intake 11 is higher than the top of the conveyor belt 4, which can quickly remove fibers and dust from the glass.
[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the industrial vacuum cleaner is connected to the industrial vacuum cleaner interface 10, the high-pressure air pump is connected to the high-pressure air pump interface 12, and the air knife 13 sprays out a high-speed airflow to blow away the dust fibers on the glass surface, loosening and blowing away some of them. The remaining dust is quickly collected into the vacuum cleaner by the suction port 11.
[0027] A concave frame 14 is fixedly connected to the right side of the concave cover 9. A laser rangefinder 15 is installed at the middle position of the top of the concave frame 14. Two sets of first electric cylinders 16 are installed at the front and rear ends of the top of the support frame 2. Limiting cylinders 17 are welded to the four corners of the top of the support frame 2. Limiting rods 18 are fixedly connected to the four corners of the bottom of the support plate 3. The laser rangefinder 15 and the first electric cylinders 16 are electrically connected. The outer diameter of the limiting rod 18 is the same as the inner diameter of the limiting cylinder 17, which facilitates the adjustment of the glass height.
[0028] Specifically, such as Figure 1 and Figure 2 As shown, the laser rangefinder 15 on the concave frame 14 measures the actual thickness of the glass. The first electric cylinder 16 extends and retracts according to the glass thickness, and the height of the support plate 3 and the conveyor belt 4 is changed. The height of the glass plate also changes synchronously. The limit rod 18 slides up and down along the inside of the limit cylinder 17, which can make the up and down movement of the support plate 3 smoother.

[0031] Working Principle: In use, the glass plate is first placed horizontally on the conveyor belt 4, which transports the glass to below the UV printing nozzle 8. As the glass is placed on the conveyor belt 4, the two sets of second electric cylinders 20 on the electric cylinder fixing frame 19 extend synchronously. The four sets of second electric cylinders 20 push the push plate 22 simultaneously towards the side of the glass, pushing the glass to the middle position. The pressure sensor 21 can sense the pressure of the two sets of push plates 22 to prevent excessive pressure from causing the glass to break. When the glass plate passes under the concave frame 14, the laser rangefinder 15 measures the actual thickness of the glass. The first electric cylinder 16 extends and retracts according to the glass thickness, and the height of the support plate 3 along with the conveyor belt 4 is changed accordingly. The height of the glass plate also changes synchronously. The limiting rod 18 slides up and down along the inside of the limiting cylinder 17, which makes the up and down movement of the support plate 3 smoother. The longitudinal servo drive module 6 drives the servo drive displacement block 7 to move back and forth. While the UV printing nozzle 8 is moving, it accurately sprays ink onto the glass surface for rapid printing. Before printing, the glass passes under the concave cover 9.
