Description

Technical Field

[0001] This invention relates to the field of UV printer technology, and more specifically to a UV printer dust removal device. Background Technology

[0002] A UV printer is an inkjet printer that sprays UV ink onto the surface of a material through a printhead. Then, ultraviolet light emitted by an LED cold light source cures the ink within one second, forming a scratch-resistant three-dimensional coating. However, during the printing process, some ink particles splash into the air, which can pollute the air in the working environment and affect the health of the workers. Moreover, dust on the surface of the material can also affect the printing effect. In order to solve the above problems, this invention provides a UV printer dust removal device. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a dust removal device for a UV printer that uses negative pressure suction to prevent ink particles from splashing into the air, while also removing dust from the surface of the printing material under negative pressure.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a dust removal device for a UV printer, comprising: A suction frame is installed on the outside of the printer nozzle and is fixedly sleeved on the lower outer side of the printer nozzle. The suction tube is fixedly connected to the suction frame and connects the suction frame to the external negative pressure suction device. When the external negative pressure device is activated, the suction tube can make the inside of the suction frame negative pressure, thereby sucking up splashed ink particles and dust on the surface of the printing material. The suction frame, when moving with the printer nozzle, is used to suction ink particles splashed during printing, as well as dust on the printing material.

[0005] Preferably, cleaning parts for assisting in cleaning dust from the surface of the printing material are installed on both sides of the suction frame and the printer nozzle along the X-axis movement direction, and limiting parts are installed on both sides of the suction frame and the printer nozzle along the Y-axis movement direction.

[0006] Preferably, the cleaning unit includes: The main shaft is rotatably mounted on the suction port sidewall outside the suction frame; Multiple silicone sheets are fixedly mounted on the main shaft and distributed circumferentially along the main shaft; The width of the silicone sheet is greater than the distance between the spindle and the printing material. Under the suction action of the suction frame, the spindle will rotate along the direction of airflow. The silicone sheet scrapes the surface of the material during rotation, removing stubborn dust. At the same time, the surface roughness of the printed pattern area is reduced by approximately after being scraped by the silicone sheet, thus improving the gloss of the pattern.

[0007] Preferably, a spring plate is provided above the main shaft. The spring plate is fixedly connected to the outer side of the suction frame, and the lower side of the spring plate is inclined away from the suction frame. Under its own elastic force, it overlaps the main shaft. The spring plate can ensure that the outside air can only flow into the suction frame through the lower part of the main shaft. At the same time, the spring plate is inclined so as not to affect the passage of the silicone sheet.

[0008] Preferably, the limiting part includes a support unit, which is mounted on the suction frame, and a plurality of ball bearings are rotatably mounted on the lower side of the support unit.

[0009] Preferably, the support unit is composed of multiple splicing plates, each splicing plate having a ball bearing rotatably mounted on its lower side, and the splicing plate being slidably mounted on the inner sidewall of the suction frame.

[0010] Preferably, a fixing plate is fixedly connected above the splicing plate and on the inner side wall of the suction frame, and a spring is connected between the splicing plate and the fixing plate.

[0011] Preferably, the outer side of the air inlet of the suction frame is vertical, and the lower end of the inner side is inclined towards the printer nozzle.

[0012] Preferably, the inner side of the air inlet of the suction frame is provided with a spring frame, the spring frame is made of elastic material, and one side of the spring frame is fixedly connected to the inner wall of the suction frame, while the other side is in contact with the inner wall of the suction frame under its own elastic force.

[0013] Preferably, the suction tube comprises: The main pipe is connected to an external negative pressure suction device; Multiple branch pipes are fixedly connected to and communicate with the main pipe, and the end of the branch pipe away from the main pipe communicates with the suction frame.

[0014] The beneficial effects of this invention are as follows: This invention, through the design of a suction frame and suction tube, enables the activation of an external negative pressure suction device during the printing process. This allows air to enter the interior of the suction frame through the gap between the suction frame and the printing material, thereby preventing ink particles from splashing into the air during printing, polluting the surrounding air, and affecting the user's health. Furthermore, negative pressure suction can also clean dust from the surface of the printing material, improving print quality.

[0015] This invention, through the arrangement of the spindle and silicone sheet, enables the spindle to rotate in the direction of airflow during the printing process. This allows the silicone sheet to clean the surface of the printing material, thereby improving the cleaning effect. Furthermore, the silicone sheet can also scrape the printed area after printing, polishing the surface of the printed pattern, improving the smoothness of the printed pattern surface, and enhancing the printing effect.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] This invention provides a dust removal device for a UV printer, such as... Figures 1 to 9 As shown.

[0029] Example 1: A dust removal device for a UV printer includes a suction frame 1 and a suction pipe. The suction frame 1 is installed on the outside of the printer nozzle 2. The suction port of the suction frame 1 is located on the lower side of the suction frame 1, and the outer side of the air inlet of the suction frame 1 is vertical, while the lower end of the inner side is inclined towards the printer nozzle 2. This design is beneficial for guiding air, ink particles, dust and other impurities into the suction frame 1, thereby improving the suction efficiency.

[0030] The inner side of the air inlet of the suction frame 1 is provided with a spring frame 10. The spring frame 10 is made of elastic material. One side of it is fixedly connected to the inner wall of the suction frame 1, and the other side is attached to the inner wall of the suction frame 1 under its own elastic force, forming a one-way flow structure. This prevents ink particles inside the suction frame 1 from falling back onto the printing material surface when the external negative pressure suction device is turned off, thus affecting the printing effect.

[0031] The main pipe 11 of the suction tube is connected to an external negative pressure suction device. Multiple branch pipes 12 are evenly distributed on the main pipe 11 and communicate with it. The end of the branch pipe 12 away from the main pipe 11 is connected to different positions of the suction frame 1, so that a uniform negative pressure environment is formed inside the suction frame 1, ensuring effective suction of ink particles splashed from all directions and dust on the surface of the printing material.

[0032] During the printing process, the external negative pressure suction device is activated. Air enters the suction frame 1 through the gap between the suction frame 1 and the printing material, carrying ink particles and dust. The air is then drawn to the external processing equipment through the branch pipe 12 and the main pipe 11. At the same time, some dust on the surface of the printing material is peeled off by the airflow and discharged after flowing into the main pipe 11 through the branch pipe 12. The spring frame 10 opens and closes adaptively in response to changes in airflow, which ensures dust collection efficiency and reduces the risk of pollution when the equipment is shut down.

[0033] Example 2: Based on Example 1, in order to improve the cleaning effect on the surface of the printing material, cleaning parts (such as...) are installed on both sides of the suction frame 1 located in the X-axis movement direction of the printer head 2. Figure 1 The cleaning section (shown as the X-face) includes: A main shaft 3 and multiple silicone sheets 4 are included. The main shaft 3 is rotatably mounted on the suction port sidewall outside the suction frame 1. Multiple silicone sheets 4 are fixedly mounted on the main shaft 3 and distributed circumferentially. The width of the silicone sheets 4 is greater than the distance between the main shaft 3 and the printing material. Under the suction action of the suction frame 1, the negative pressure airflow drives the main shaft 3 to rotate along the airflow direction (as shown in the diagram). Figure 3 (Rotating in the direction of the arrow shown) During the rotation, the silicone sheet 4 located below the axis of the main shaft 3 will move towards the printer nozzle 2, thereby sweeping the dust on the surface of the printing material towards the suction port of the suction frame 1, thus better cleaning the dust on the surface of the printing material.

[0034] A spring plate 5 is provided above the main shaft 3. The spring plate 5 is fixedly connected to the outer side of the suction frame 1. Its lower side is inclined away from the suction frame 1 and overlaps the main shaft 3 under its own elastic force. This ensures that the outside air can only flow into the suction frame 1 through the lower part of the main shaft 3. The inclined design of the spring plate 5 avoids obstructing the rotation of the silicone sheet 4.

[0035] When the negative pressure airflow passes through the suction frame 1, it pushes the silicone sheet 4 to rotate, and the main shaft 3 rotates accordingly. As it rotates, the silicone sheet 4 scrapes the surface of the material, removing stubborn dust. At the same time, the surface roughness of the printed pattern area is reduced by approximately 10% after being scraped by the silicone sheet 4, thus improving the gloss of the pattern.

[0036] Example 3: Based on Embodiment 1, in order to ensure that the distance between the printing material and the suction frame 1 remains stable during operation, limiting parts (such as...) are installed on both sides of the suction frame 1 located in the Y-axis movement direction of the printer head 2. Figure 1 The Y-shaped surface shown includes: The limiting part includes: The support unit consists of multiple splicing plates 7, each with multiple ball bearings 6 rotatably mounted on its lower side. The splicing plates 7 are slidably mounted on the inner wall of the suction frame 1. Above the splicing plates 7, a fixing plate 8 is fixedly connected to the inner wall of the suction frame 1. A spring 9 connects the splicing plates 7 and the fixing plate 8. One end of the spring 9 is fixedly connected to the splicing plate 7, and the other end is fixedly connected to the fixing plate 8. The spring 9 has a clamping force that causes the corresponding ball bearings 6 to press against the printing material.

[0037] As the suction frame 1 moves with the printer nozzle 2, the ball bearing 6 contacts the surface of the printing material. Under the action of the spring 9, the splicing plate 7 can slide up and down to achieve adaptive height adjustment. At the same time, the clamping force of the spring 9 keeps the ball bearing 6 in contact with the surface of the printing material, acting as a limit. This process maintains a stable distance between the suction frame 1 and the material, ensuring stable negative pressure airflow. The rotation of the ball bearing 6 reduces friction between the suction frame 1 and the surface of the printing material during movement, ensuring smooth movement of the device.

[0038] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
