Description

TECHNICAL FIELD

[0001] The utility model relates to a curing device, concretely is an ink UV curing device for paperboard printing. BACKGROUND

[0002] Paperboard is a kind of thick paper or thin paperboard material made of fiber material (usually plant fiber, such as wood pulp, bamboo pulp, straw pulp, etc.), with high strength and certain thickness, widely used in packaging, printing, construction and furniture fields, and there are various types of paperboard, including corrugated paperboard, white cardboard, grey board, etc., which have different physical properties and appearance characteristics according to different purposes and production processes.

[0003] In the paperboard production process, in order to pass product information, brand value and usage instructions to consumers, various texts, patterns and logos are usually printed on the surface of paperboard, which not only helps to improve the recognition and attractiveness of products, but also meets the requirements of laws and regulations on product logos, in order to improve the curing efficiency of printing ink and ensure the efficient and smooth production process, modern paperboard printing industry generally uses UV curing device to quickly cure the ink printing area of paperboard.

[0004] In actual use, when the curing lamp of the UV curing device starts, static electricity will be generated on the surface of the lampshade, which is caused by the interaction between the high-energy ultraviolet light generated by the UV lamp during work and the surface of the lampshade. The generation of static electricity will cause the lampshade surface to adsorb dust and paperboard fibers in the surrounding environment. In the paperboard printing workshop, a large amount of fibers and dust particles will be generated due to the cutting, conveying and printing process of paperboard, which will easily adhere to the lampshade of the UV curing lamp under the action of static electricity. With the passage of time, these adhered dust and fibers will gradually accumulate to form a thin layer of dirt.

[0005] The existence of this layer of dirt will have a significant impact on the light irradiation effect of the UV curing lamp. First, the dust and fibers will absorb and scatter part of the ultraviolet light, causing the UV light intensity reaching the surface of the paperboard ink to weaken. This weakening may cause incomplete ink curing, resulting in reduced ink adhesion on the surface of the printed product, blurred printing, dull colors and other problems, thereby affecting the printing quality. Secondly, uneven dirt distribution will cause uneven irradiation intensity of UV light on the surface of the paperboard, which will further cause inconsistent ink curing effect, resulting in incomplete or excessive curing in some areas.

DETAILED DESCRIPTION

[0042] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0043] Please refer to Figures 1-6 In the embodiment of the present application, an ink UV curing device for paperboard printing comprises a main body 1, a conveying member 2 arranged on the main body 1, and a UV curing lamp 3 installed on the main body 1, wherein the main body 1 is provided with a curing and cleaning structure, and the curing and cleaning structure comprises:

[0044] A gas pipe 4 is arranged in the cavity of the main body 1, and two spray heads 6 for spraying gas to the UV curing lamp 3 are symmetrically and rotatably connected to the gas pipe 4;

[0045] A hook spring 12 is connected between the gas pipe 4 and the spray head 6, and the two spray heads 6 are connected to each other through a yawing piece rotatably arranged on the gas pipe 4;

[0046] The main body 1 is provided with a linkage member connected to a speed reduction gear set of a conveying end of the conveying member 2, the linkage member is provided with a rack 16 connected to the yawing piece, and when the conveying member 2 performs a paperboard conveying action, the rack 16 is driven by the linkage member to reciprocate, so as to make the yawing piece reciprocate, and further drive the spray head 6 to swing on the gas pipe 4 to perform a spraying and cleaning action on the UV curing lamp 3.

[0047] In this embodiment, when the paperboard moves on the conveying member 2, the power of the conveying member 2 is transmitted to the linkage member through the speed reduction gear set, the movement of the linkage member further drives the rack 16 to reciprocate, and the rack 16 is connected to the yawing piece, so that the yawing piece also reciprocates correspondingly, and the swinging is transmitted to the spray head 6 through the connection relationship, so that the spray head 6 can swing on the gas pipe 4, and further spray and clean the surface of the UV curing lamp 3, the gas pipe 4 is connected with a gas supply device outside, for supplying gas to the position of the spray head 6, to achieve the cleaning effect;

[0048] This automatic cleaning mechanism effectively solves the problem that the light irradiation effect of the UV curing lamp 3 is reduced due to static adsorption of dust and paperboard fibers during use, and through spraying and cleaning, the dirt on the surface of the lampshade can be removed in time, so as to ensure that the transmittance of UV light always remains at a high level, thereby ensuring the stability and consistency of the ink curing effect, and the speed reduction gear set can reduce the rotating speed when transmitting the power of the conveying member 2 to the curing and cleaning structure, so as to meet the use requirement, and the hook spring 12 acts between the gas pipe 4 and the spray head 6, so as to realize the rapid swinging effect of the spray head 6 on the gas pipe 4.

[0049] Please refer toFigure 10 As a further scheme of the utility model, the first slot 5 is symmetrically arranged on the gas pipe 4 at both sides of the blowing head 6.

[0050] In this embodiment, the first slot 5 is used for communication with the blowing head 6, so that the gas supplied by the gas pipe 4 can be delivered to the blowing head 6, and the blowing head 6 can blow out the gas to clean the surface of the UV curing lamp 3 by using the airflow.

[0051] Please refer to Figure 8 and Figure 9 As a further scheme of the utility model, the cavity of the blowing head 6 is provided with a plugging pipe 7, and the plugging pipe 7 is provided with a second slot 8 at the blowing port of the blowing head 6, which cooperates with the first slot 5.

[0052] The two ends of the blowing head 6 are symmetrically provided with a limiting arc-shaped slot 9.

[0053] In this embodiment, the cavity of the blowing head 6 is provided with a plugging pipe 7, which can ensure that the gas is concentrated and sprayed out of the blowing port, thereby improving the efficiency and accuracy of blowing. The second slot 8 arranged on the plugging pipe 7 cooperates with the first slot 5 on the gas pipe 4. This design enables the gas to smoothly enter the cavity of the blowing head 6 through the first slot 5 and the second slot 8 from the gas pipe 4 and finally be sprayed out of the blowing port. When the blowing head 6 swings, the second slot 8 is dislocated from the first slot 5, and at this time, the airflow in the gas pipe 4 is in a concentrated state. When the blowing head 6 swings and the second slot 8 and the first slot 5 coincide, the two are in communication, and the airflow in the gas pipe 4 can be quickly sprayed out of the blowing head 6, so that it can more effectively remove the dust and fibers on the surface of the UV curing lamp 3.

[0054] In addition, the two ends of the blowing head 6 are symmetrically provided with a limiting arc-shaped slot 9, which provides a precise limiting function for the swinging movement of the blowing head 6. The existence of the limiting arc-shaped slot 9 ensures that the blowing head 6 always remains in the predetermined track and range during the swinging process, avoiding structural damage or deviation of the blowing direction caused by excessive swinging.

[0055] Please refer to Figure 7 , Figure 8 and Figure 11 As a further scheme of the utility model, the two ends of the blowing head 6 are provided with a hooking pin head, and the hooking pin head is hookingly connected with one end of the hook spring 12.

[0056] The other end of the hook spring 12 is connected with the fixed frame 10 fixed on the gas pipe 4, and the fixed frame 10 is provided with another hooking pin head connected with the hook spring 12.

[0057] Two limiting pins 11 are symmetrically arranged on the fixed frame 10 and slide in the limiting arc-shaped slots 9.

[0058] In this embodiment, the blowing head 6 is rotationally connected with the air pipe 4 to ensure that the blowing head 6 can keep flexible movement and stable connection during swinging, and the two ends of the blowing head 6 are provided with hooking pin heads connected with one end of the hook spring 12 to form an elastic connection.

[0059] The other end of the hook spring 12 is connected to the fixed frame 10 arranged on the air pipe 4, and the fixed frame 10 is also provided with hooking pin heads connected with the hook spring 12 to meet the connection and use effect.

[0060] Please refer to Figure 7 and Figure 12 , as a further scheme of the utility model, the yawing piece includes two connecting rods 13 symmetrically arranged on the two sides of the air pipe 4, a connecting block 14 slidingly inserted on the connecting rods 13 and installed on the blowing head 6, and a gear 15 rotationally arranged on one end of the connecting rods 13.

[0061] The gear 15 is rotationally connected with the air pipe 4, and the gear 15 is in meshing connection with the rack 16.

[0062] The rotation angle of the gear 15 on one end of the connecting rods 13 is forty degrees.

[0063] In this embodiment, the design of the yawing piece realizes the reciprocating swinging function of the blowing head 6, thereby ensuring effective cleaning of the surfaces of the UV curing lamps 3 on the two sides.

[0064] One end of the connecting rod 13 is rotatably provided with a gear 15, which is rotatably connected to the air pipe 4 and is in meshing connection with a rack 16 on the linkage. When the conveying member 2 drives the paperboard to perform the conveying action, the linkage drives the gear 15 to rotate through the reciprocating movement of the rack 16. Since the gear 15 is connected to the connecting rod 13 and the rotation angle between the gear 15 and the connecting rod 13 is forty degrees, when the gear 15 is driven to rotate by the rack 16, only when one end of the notch on the gear 15 abuts against one end of the connecting rod 13, the connecting rod 13 can be driven to rotate. When the gear 15 rotates and the hook spring 12 passes the position of the balance point, under the rebounding force of the hook spring 12, the connecting rod 13 can drive the blowing head 6 to rapidly swing. At this time, the rotation connection between the gear 15 and the connecting rod 13 does not affect the rapid swinging action of the connecting rod 13 and the blowing head 6. The rotation of the gear 15 can further drive the connecting rod 13 and the blowing head 6 to reciprocate. This design of realizing the swinging of the blowing head 6 through the meshing transmission of the gear 15 and the rack 16 not only ensures the accuracy and stability of the movement of the blowing head 6, but also can be synchronously adjusted according to the movement speed and rhythm of the conveying member 2. This means that the swinging frequency and amplitude of the blowing head 6 can be optimized according to the conveying speed of the paperboard, so that the surface of the UV curing lamp 3 can be uniformly cleaned.
