Description

Technical Field

[0001] This utility model relates to the technical field of UV ink processing, and in particular to a feeding device for UV ink processing. Background Technology

[0002] UV ink, also known as ultraviolet-cured ink, is a type of ink that uses ultraviolet radiation to form a film and dry. Under ultraviolet light, UV ink transforms from liquid ink to solid through a photochemical reaction, resulting in characteristics such as fast drying speed, high gloss, and vibrant colors. A feeding device for UV ink processing (Announcement No.: CN216856463U) features a circulation mechanism. During operation, a second motor drives a spiral feeder inside the feeding pipe, which in turn drives the ink flowing into the pipe. A control valve then re-pours the ink from the bottom of the mixing tank back into the mixing tank, further improving mixing efficiency. After mixing is complete, the control valve is closed, opening the discharge valve. A third motor is then activated to discharge the mixed ink for auxiliary feeding. During this process, a filter screen effectively filters the ink, thus improving the stability of the feeding process and the quality of the ink.

[0003] As mentioned above, the circular heating plate positioned on the lower inner wall of the mixing chamber may result in uneven heating, especially for larger volumes of ink, where areas farther from the heating plate may not receive sufficient heat. Impact: Uneven heating leads to inconsistent curing and drying rates of the ink, affecting its quality and performance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device for UV ink processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding device for UV ink processing includes a tank, a pump body installed in the tank, an interlayer between the outer and inner layers of the tank, a curved tube movably passing through the tank, a screw threadedly connected to the curved tube, a first motor installed in the tank, the output end of the first motor connected to the screw, a heating plate installed at one end of the curved tube, the heating plate and part of the curved tube placed in the interlayer, and a sleeve slidably connected to the curved tube, the sleeve being connected to the tank.

[0007] Preferably, a plate is placed at the tank body, and an opening is provided at one end and the other end of the plate. A block is placed at each of the multiple openings, and the multiple blocks are connected to the tank body. A stop block is slidably connected to each of the multiple blocks, and a spring is connected between the multiple stops and the corresponding blocks. The multiple stops are in contact with the plate body.

[0008] Preferably, a first valve body and a second valve body are connected to one end and the other end of the tank body, and both the first valve body and the second valve body are connected to the interlayer.

[0009] Preferably, the tank body is connected to multiple sets of bases.

[0010] Preferably, the tank body is made of stainless steel.

[0011] Preferably, a second motor is installed at the plate, and the output section of the second motor is connected to the stirring rod.

[0012] Preferably, a lifting ring is connected to one end and the other end of the plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the coordinated design of the tank, pump, jacket, heating plate, and curved tube, water is injected into the jacket and heated by the heating plate. From a heating uniformity perspective, water, as the heating medium, due to its excellent thermal conductivity and fluidity, can evenly transfer heat to all parts of the tank, avoiding localized overheating or underheating. This ensures uniform temperature of the UV ink within the tank, consistent curing and drying rates, effectively preventing ink separation and clumping, guaranteeing ink quality, and laying a solid foundation for material feeding and subsequent printing operations. Regarding heating adjustment, the screw-driven curved tube allows for adjustment of the heating plate height, offering high flexibility. Adjustments can be made based on the actual situation such as the amount and distribution of ink within the tank; for example, the heating plate position can be lowered when the ink volume is low and raised when the ink volume is high. Simultaneously, it can adapt to different production conditions and ink characteristics, meeting the heating requirements of various UV inks, ensuring the ink is in a suitable temperature environment at different production stages, and guaranteeing material feeding stability.

[0015] 2. By coordinating the plate, opening, block, stop, and spring, the plate can be quickly assembled and disassembled by placing the opening on the plate against the block on the tank, and by placing the stop on the block against the top of the plate. This allows for easy separation of the stirring rod from the tank and easy replacement of parts. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5A feeding device for UV ink processing includes a tank 1, a pump 2 installed in the tank 1, the model of the pump 2 being selected according to actual working requirements, the pump 2 being used to transport and feed the UV ink into the tank 1, and an interlayer 3 being provided between the outer and inner layers of the tank 1, the interlayer 3 playing a key role in the heating process of the device. It provides storage space for the heating medium, allowing the heat to be transferred more evenly to the ink inside the tank 1. A curved tube 5 is movably connected through the tank 1, and a screw 8 is threadedly connected to the curved tube 5. A first motor 7 is installed in the tank 1. The model of the first motor 7 is selected according to the actual working requirements. The output end of the first motor 7 is connected to the screw 8. A heating plate 4 is installed at one end of the curved tube 5. The heating plate 4 and part of the curved tube 5 are placed in the interlayer 3. A sleeve 6 is slidably connected to the curved tube 5. The function of the sleeve 6 is to support and guide the curved tube 5, ensuring that the curved tube 5 can move smoothly during the adjustment of the height of the heating plate 4 without deviation or shaking, thereby ensuring that the position adjustment of the heating plate 4 is accurate and reliable. The sleeve 6 is connected to the tank 1. When the equipment is working, the heating plate 4 will heat the heating medium (such as water) in the interlayer 3. Because water has excellent thermal conductivity and fluidity, heat is evenly transferred to all parts of the tank 1, thus achieving uniform heating of the ink. Simultaneously, the screw 8 drives the curved tube 5 to adjust the height of the heating plate 4, providing high flexibility. It can adjust the position of the heating plate 4 according to the amount of ink in the tank 1, the ink distribution, and different production conditions and ink characteristics. For example, when the amount of ink in the tank 1 is small, the position of the heating plate 4 can be lowered to concentrate heat more in the ink area; when the amount of ink is large, the position of the heating plate 4 can be raised to ensure uniform heating of the entire ink layer. Furthermore, for inks at different production stages and with different characteristics, the heating requirements can be met by adjusting the position of the heating plate 4, ensuring that the ink is fed and transported under suitable temperature conditions.

[0024] In this embodiment, a plate 9 is placed at the tank body 1. Each end of the plate 9 has an opening 10. Multiple blocks 11 are fitted into each opening 10, and each block 11 is connected to the tank body 1. Each block 11 is slidably connected to a stop 12, and a spring 13 connects the stop 12 to its corresponding block 11. Each stop 12 is in contact with the plate 9. A first valve body 17 and a second valve body 19 are connected to each end of the tank body 1. Both the first valve body 17 and the second valve body 19 are connected to the interlayer 3. The function of these two valve bodies is to control the entry and exit of the heating medium (such as water) within the interlayer 3. By properly operating these two valves, the heating medium in the jacket 3 can be replenished, replaced, or discharged, thereby better controlling the heating process. Multiple sets of bases 16 are connected to tank 1, which is made of stainless steel. A second motor 14 is installed on plate 9, and its output is connected to the stirring rod 15. The model of the second motor 14 is selected according to actual working requirements. When the equipment is working, the second motor 14 drives the stirring rod 15 to rotate, agitating the ink in tank 1. The stirring function prevents ink separation and ensures uniform mixing of ink components, thereby improving ink quality and feeding stability. Lifting rings 18 are connected to one end and the other end of plate 9, facilitating the installation and removal of plate 9. When maintenance or replacement of the stirring rod 15 or related components of plate 9 is required, plate 9 can be easily removed from tank 1 using the lifting rings 18, improving the convenience of equipment maintenance.

[0025] The working principle of this embodiment is as follows: During use, water can be injected into the jacket 3 at the second valve body 19. After injection, the heating plate 4 is connected to an external power supply and drive device. After connection, the heating plate 4 will heat the water in the jacket 3. When the water is heated, the tank 1 can be heated evenly with the help of the water. At this time, when the UV ink is poured into the tank 1 and continuously transported by the pump body 2, the UV ink will be heated evenly, ensuring a consistent curing and drying rate, effectively preventing ink stratification and clumping, ensuring ink quality, and laying a good foundation for feeding and subsequent printing operations. At the same time, the rotation of the screw 8 driven by the first motor 7 can be used to adjust the position of the curved tube 5 and the heating plate 4 to adapt to different production conditions and ink characteristics. It can also be used in conjunction with the second motor 14 to drive the stirring rod 15 to stir the UV ink, avoiding problems such as UV ink stratification and ensuring processing after feeding.
