Abstract
Description
Technical Field
[0001] This utility model relates to the field of label manufacturing, specifically to a label drying device. Background Technology
[0002] After the labels are printed, the ink on the labels needs to be dried. The conventional drying methods are heating with lamps or heating with hot air.
[0003] Heating is achieved by using lamps, but since the heating method is static (without air circulation), it is not conducive to improving air flow and moisture evaporation, resulting in low heating efficiency.
[0004] Heating is achieved using hot air. Hot air is blown from an air outlet onto the label, exerting a certain air pressure. The air continuously blows onto the label, and because the heating is dynamic (the gas is in a flowing state), hot air heating is more effective at evaporating moisture compared to light heating, improving airflow and volatility. However, since the air is blown from the outlet, the area of the label that receives the hot air is relatively fixed. The parts of the label directly opposite the outlet dry faster due to the direct heat, while the parts not directly opposite the outlet dry more slowly. Therefore, using a single hot air heating method is not conducive to even heating of the label, and the heating uniformity needs improvement.
[0005] In summary, current label drying devices rely on a single heating method, either hot air or light, and the heating and drying effects need to be improved.
[0006] To improve the heating effect, those skilled in the art may think of using a heating and drying method that combines a hot air heating and drying device and a light heating and drying device. However, using two different devices side by side will increase the space occupied by the device. At the same time, the label passes through two different devices, which prolongs the label movement path and reduces the drying efficiency of the label. Utility Model Content
[0007] The present invention aims to provide a label drying device that enables simultaneous light heating and hot air heating, thereby solving the problem that current drying devices can only perform drying using either light heating or hot air heating, and improving the label drying effect.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: a label drying device, including a blower box, an air chamber inside the blower box, an air inlet on the blower box communicating with the air chamber, a plurality of lamp mounting slots for placing lamps on the outside of the blower box, and air outlets on the blower box located on both sides of the lamp mounting slots, the air outlets communicating with the air chamber.
[0009] The principle and advantages of this solution are as follows: Labels coated with ink pass through this label drying device, which heats and dries the labels. During drying and heating, hot air is introduced into the blowing chamber inside the blowing box through the air inlet. The hot air enters the blowing chamber and is blown out from different air outlets. The hot air blown out from the outlets acts on the label, exerting a certain air pressure on it. The continuous blowing of air onto the label facilitates moisture evaporation, improves airflow and volatility, and thus promotes the evaporation and drying of the ink on the label. Simultaneously, multiple lamp mounting slots are equipped with lamps, which can be turned on to emit light and heat, baking the label and thus drying it.
[0010] Therefore, through this solution, the label drying device can simultaneously perform hot air heating and lamp heating. The hot air has a certain air pressure, which dries the ink on the label and facilitates moisture evaporation. The lamp has a wide irradiation range, which ensures uniform heating. In this way, the two methods of hot air heating and lamp heating can be carried out at the same time, which greatly improves the heating and drying effect.
[0011] This device integrates both light heating and hot air heating. When heating labels with light and hot air, there is no need to arrange the light heating device and hot air heating device side by side, which greatly reduces the space occupied by the heating and drying device. At the same time, the labels do not need to pass through two different devices, and the label movement path is not extended, so the drying efficiency of the labels can be guaranteed.
[0012] Furthermore, although this device integrates both light-based heating and hot-air heating, this does not mean that both methods can be used simultaneously in actual use. In practice, you can choose either light-based heating or hot-air heating depending on the specific situation, the type of ink on the label, and the ink thickness. This allows the device to meet different heating needs with a single unit, eliminating the need for two separate drying systems.
[0013] Preferably, as an improvement, the lamp mounting groove is arc-shaped. The arc-shaped lamp mounting groove matches the arc-shaped lamp.
[0014] Preferably, as an improvement, the blower box includes a blower box body with an opening and a lamp mounting slot. There are multiple lamp mounting slots arranged in parallel, and there is a gap between adjacent lamp mounting slots to form the blower opening. The lamp mounting slots are installed at the opening of the blower box body.
[0015] Therefore, the lamp mounting slot is installed at the opening of the blower housing, and the gap between the lamp mounting slot and the blower housing forms the blower chamber. Since there is a gap between adjacent lamp mounting slots, hot air in the blower chamber can be blown out through this gap. Thus, the gap between adjacent lamp mounting slots serves as the air outlet. The air outlet does not need to be manufactured separately; it can be formed between adjacent lamp mounting slots simply by assembling the lamp mounting slots.
[0016] Preferably, as an improvement, a connecting bracket connects the multiple lamp mounting slots, and the connecting bracket is fixed to the blower housing. Thus, the connecting brackets connect and fix the multiple lamp mounting slots. By fixing the connecting brackets to the blower housing, the lamp mounting slots and the blower housing are connected and fixed.
[0017] Preferably, as an improvement, the blower box includes a blower box body and a blower box cover plate fixed at the end of the blower box body.
[0018] Preferably, as an improvement, it also includes a return air box, which has a return air chamber and an opening communicating with the return air chamber. The blower box is installed in the return air chamber, and the lamp mounting slot and the blower outlet are exposed through the opening of the return air box.
[0019] There is a gap between the outer wall of the blower box and the inner wall of the return air box to form a return air inlet. The return air inlet is connected to the return air chamber, and the return air box is provided with an air outlet that is connected to the return air chamber.
[0020] Therefore, this device incorporates a return air structure. Hot air blown from the air outlet acts on the label, and then enters the return air chamber through the return air inlet. The hot air then flows out from the air outlet, is reheated by the heating equipment, and re-enters the air inlet before being blown out from the air outlet of the blower box. Thus, this device achieves hot air recovery and recycling, avoiding waste of hot air blown from the air outlet.
[0021] Preferably, as an improvement, an air outlet duct is fixedly connected to the air outlet. Thus, hot air in the return air chamber flows out through the air outlet duct.
[0022] Preferably, as an improvement, the side wall of the return air box is provided with a through hole, and an air inlet pipe is connected to the air inlet, passing through the through hole. Thus, hot air enters the blower box through the air inlet pipe. The through hole ensures that the return air box does not obstruct the air inlet pipe from extending out of the return air box, allowing the blower box to be mounted on the return air box while the air inlet pipe can extend out from it.
[0023] Preferably, as an improvement, the return air box includes a return air box body and a return air box cover plate. The return air box body has an inlet corresponding to the through hole, and the return air box cover plate covers the inlet.
[0024] Therefore, the design of the connector allows the blower box to be inserted into the return air box from the connector, so that the air inlet pipe can be inserted into the through hole. After the blower box is installed on the main body of the return air box, the return air box cover is placed on the main body of the return air box.
[0025] Preferably, as an improvement, it also includes a limiting plate, which is opposite to the lamp mounting slot. Thus, the limiting plate faces the air box, and the label passes between the limiting plate and the air box. When hot air blows onto the label, the limiting plate provides some support, preventing the label from moving away from the air box due to the airflow. Attached Figure Description

Bending part; 19. Edge.
[0034] The basic implementation examples are as follows: Figures 1-6 As shown: A label drying device includes an air blowing box 11, a return air box 1, and a limiting plate 2. The air blowing box 11 is installed in the return air box 1, and the limiting plate 2 is located outside the air blowing box 11, with the limiting plate 2 and the air blowing box 11 facing each other.
[0035] Combination Figures 2-6As shown, the blower box 11 in this embodiment includes a blower box body with an opening and a lamp mounting slot 15. The lamp mounting slot 15 is a plate bent into an arc shape, and an arc-shaped lamp mounting groove 6 is provided on the lamp mounting slot 15 for placing the lamp. Combined with... Figure 5 As shown, this embodiment has multiple lamp mounting slots 15 arranged in parallel, with gaps between the edges 19 of adjacent lamp mounting slots 15 forming air vents 7. A connecting frame 14 connects the bottom ends of the multiple lamp mounting slots 15. The connecting frame 14 is an L-shaped plate, and the connection method is as follows: the bottom ends of the lamp mounting slots 15 have connecting holes, which are installed on the connecting frame 14 using screws or bolts 16. In this embodiment, there are two connecting frames 14, located at both ends of the lamp mounting slots 15 respectively. The two connecting frames 14 connect and fix the multiple lamp mounting slots 15 together, thus achieving the assembly and fixation of the multiple lamp mounting slots 15 together.
[0036] Combination Figure 4 and Figure 6 As shown, the blower box in this embodiment includes a blower box body 17 and blower box cover plates 13 fixed at both ends of the blower box body 17. The top of the blower box body 17 has an opening, and the left and right ends of the blower box body 17 are connected. Two blower box cover plates 13 are located at the left and right ends of the blower box body 17, and the blower box cover plates 13 can close the ends of the blower box body 17. The top edge of the blower box body 17 has a bent portion 18, and the lamp tube mounting groove 15 is installed in the opening of the blower box. The bent portion 18 abuts against and covers the top edges 19 of the lamp tube mounting grooves 15 on both the front and rear sides.
[0037] In some embodiments, the connecting frame 14 and the blower housing cover 13 can be welded or fixed by bolts or screws, thereby fixing the connecting frame 14 and the blower housing. The blower housing cover 13 and the ends of the blower housing body 17 are welded together.
[0038] After the blower box body 17, blower box cover 13, and lamp tube mounting slot 15 are installed, the inside of the blower box 11 (between the blower box body 17 and the lamp tube mounting slot 6) is provided with a blower chamber. One of the blower box cover 13 is provided with an air inlet that connects to the blower chamber, and an air inlet pipe 4 is welded and fixed at the air inlet.
[0039] In this embodiment, since the air outlet 7 is located between the edges 19 of the adjacent lamp tube mounting slots 15, and the lamp tube mounting slots 6 are used to place lamp tubes, the air outlet 7 on the air box 11 in this embodiment is located between the adjacent lamp tube mounting slots 6, and the air outlet 7 is connected to the air chamber.
[0040] Combination Figure 2 and Figure 3 As shown, in this embodiment, the return air box 1 is provided with a return air chamber 10 and an opening communicating with the return air chamber 10. The blower box 11 is installed in the return air chamber 10, and the lamp tube mounting groove 6 and the blower 7 are exposed through the opening of the return air box 1.
[0041] A gap exists between the outer wall of the blower box 11 and the inner wall of the return air box 1 to form a return air inlet 5, which is connected to the return air chamber 10.
[0042] In this embodiment, the return air box 1 specifically includes a return air box body and a return air box cover plate 9. One end of the return air box body is provided with a through hole 8 and an air outlet, and an air outlet pipe 3 is welded to the air outlet. The other end of the return air box body is provided with an insertion port opposite to the through hole 8. Thus, the blower box 11 is inserted into the return air box 1 body through the insertion port of the return air box body, and the air inlet pipe 4 on the blower box 11 is inserted into the through hole 8 and extends out of the through hole 8. Then, the return air box cover plate 9 is closed on the insertion port, thereby realizing the installation of the blower box 11 in the return air box 1.
[0043] The specific implementation process is as follows: The label coated with ink passes between the limiting plate 2 and the return air box 1. At the same time, hot air is introduced into the blowing chamber inside the blowing box 11 through the air inlet pipe 4. The hot air enters the blowing chamber and is blown out from different air outlets 7. The hot air blown out from the air outlets 7 acts on the label. The blown hot air has a certain air pressure on the label. The air is constantly blowing on the label, which is conducive to moisture evaporation, improves air flow and volatility, and thus facilitates the evaporation and drying of the ink on the label. At the same time, a negative pressure pipe is connected to the air outlet pipe 3. The return air chamber 10 has a negative pressure. The blown air enters the return air chamber 10 inside the return air box 1 through the return air inlet 5 and flows out from the air outlet pipe 3. The outflowing air flows to the heating equipment (such as an electric heater or heat exchanger) through the negative pressure pipe. The heating equipment heats the gas. The heated gas then flows back to the air inlet pipe 4 through the pump and pipe, thus continuously supplying hot air to the blowing chamber. Therefore, the hot air blown out from the air outlet 7 is recovered through the return air outlet 5, and then reheated for reuse. The hot air is not wasted, realizing the recycling of hot air and reducing the waste of hot air.
[0044] Meanwhile, multiple lamp mounting slots 6 are equipped with lamps. During the hot air drying process, the lamps can be turned on to emit light and heat, which bakes the label and dries it.
[0045] Therefore, this device combines light heating and hot air heating, resulting in better drying and heating effects.
[0046] Of course, in other implementations, heating can also be achieved by using light or hot air.
