Description

Technical Field

[0001] This utility model relates to the field of paper-based drying technology, specifically to a rapid paper-based drying device for masking paper production. Background Technology

[0002] Masking tape is a type of tape made with crepe paper as the base material and coated with a special pressure-sensitive adhesive. It is usually sold in rolls, available in various widths and lengths to suit different needs. Masking tape has excellent masking properties, allowing for precise coverage of areas that do not require coloring or treatment during spray painting, coating, and decoration work, preventing paint, stains, etc., from spreading to other areas and providing protection. It has moderate adhesion, adhering firmly to surfaces while being easily removed after use without leaving residue or damaging the surface.

[0003] In interior decoration, it is often used to cover doors, windows, furniture, and corners to prevent paint from getting on areas that don't need to be painted when painting walls or spraying paint. It can also be used to protect grout lines when laying tiles, and to temporarily cover and protect floors and fixed installations during post-construction cleaning.

[0004] The production process of masking tape includes material selection, pulping, dewatering, masking treatment, drying, cutting, and packaging. After dewatering, the paper base still contains a certain amount of moisture and needs to be dried quickly to meet subsequent processing requirements. For example, if the moisture content of the paper base is too high, it may lead to problems such as unclear printing and uneven glue application during masking treatment, affecting the appearance and performance of the masking tape.

[0005] Regarding the existing related technologies, the inventors believe that the following defects exist: traditional natural air drying or simple drying methods are slow and cannot meet the needs of large-scale industrial production; early single-cylinder drying devices have long drying times on the surface of the drying cylinder, resulting in low production efficiency. Utility Model Content

[0006] To address the problems of slow drying speeds in traditional air-drying or simple drying methods, which cannot meet the needs of large-scale industrial production, and the low production efficiency caused by long drying times of paper base on the drying cylinder surface in early single-cylinder drying devices, this utility model provides a rapid drying device for paper base in masking paper production.

[0007] This utility model is achieved using the following technical solution: a rapid drying device for paper base in masking paper production, comprising a base and a drying chamber. A conveyor belt is provided on the top of the base, and the bottom of the drying chamber is fixedly connected to the top of the conveyor belt. A motor is provided on the top of the drying chamber, and a threaded rod is fixedly connected to the bottom of the motor. A horizontal plate is threadedly connected to one end of the threaded rod. Two closed doors are fixedly connected to both ends of the horizontal plate, and the two closed doors are movably connected to the interior of both ends of the drying chamber. Two connecting columns are fixedly connected to the bottom of the horizontal plate, and a fixed plate is fixedly connected to the bottom of the connecting columns. An infrared radiator is provided at the bottom of the fixed plate.

[0008] Preferably, the drying oven has slots at both ends, and the closing door is movably connected inside the slots.

[0009] Preferably, the top of the drying oven is fixedly connected to two guide rods, and the two sides of the horizontal plate are fixedly connected to two limiting plates, which are movably connected to the outside of the guide rods.

[0010] Preferably, a top plate is fixedly connected to the top of the guide rod, and the motor is located on top of the top plate.

[0011] Preferably, one end of the connecting column is movably connected to the top of the drying chamber, and the infrared radiator is located inside the drying chamber.

[0012] Preferably, the top of the drying oven is machined with multiple filter holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When this utility model is in use, starting the motor will drive the threaded rod to rotate, which will drive the horizontal plate to move downward. The horizontal plate will then drive the closing door downward to close both sides of the drying chamber. At the same time, the horizontal plate will drive the fixed plate and infrared radiator upward through the connecting column to move above the masking paper base. The infrared radiator emits infrared rays, which cause the moisture in the paper base to evaporate rapidly. Infrared rays have strong penetrating power and can penetrate deep into the paper base, achieving simultaneous drying inside and out, resulting in higher production efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a rapid drying device for masking tape production includes a base 1 and a drying chamber 2. A conveyor belt 3 is installed on the top of the base 1. The bottom of the drying chamber 2 is fixedly connected to the top of the conveyor belt 3. A motor 5 is installed on the top of the drying chamber 2. A threaded rod 6 is fixedly connected to the bottom of the motor 5. A horizontal plate 7 is threadedly connected to one end of the threaded rod 6. Two closed doors 4 are fixedly connected to both ends of the horizontal plate 7. The two closed doors 4 are movably connected to the inside of both ends of the drying chamber 2. Two connecting columns 8 are fixedly connected to the bottom of the horizontal plate 7. A fixed plate 9 is fixedly connected to the bottom of the connecting columns 8. An infrared radiator 10 is installed at the bottom of the fixed plate 9. One end of the connecting columns 8 is movably connected to the top of the drying chamber 2. The infrared radiator 10 is located inside the drying chamber 2.

[0021] In this process, by starting the motor 5, the motor 5 will drive the threaded rod 6 to rotate, the rotation of the threaded rod 6 will drive the horizontal plate 7 to move upward, the horizontal plate 7 will drive the connecting column 8 to move upward, the connecting column 8 will drive the fixed plate 9 to move upward, the fixed plate 9 will drive the infrared radiator 10 to move upward, and at the same time the horizontal plate 7 will drive the two closed doors 4 to move upward, thereby opening the interior of the drying oven 2, and the masking paper base will be conveyed into the interior of the drying oven 2 by the conveyor belt 3.

[0022] Secondly, when the masking paper base is conveyed into the drying chamber 2, the motor 5 is started. The motor 5 will drive the threaded rod 6 to rotate, the threaded rod 6 will drive the horizontal plate 7 to move downward, and the horizontal plate 7 will drive the sealing door 4 to move downward to close both ends of the drying chamber 2. At the same time, the horizontal plate 7 will drive the fixed plate 9 and the infrared radiator 10 to move upward above the masking paper base through the connecting column 8. The infrared radiator 10 emits infrared rays. When the infrared rays irradiate the masking paper base, they are absorbed by the paper base and converted into heat energy, causing the moisture in the paper base to evaporate rapidly. Infrared rays have strong penetrating power and can penetrate deep into the interior of the paper base to achieve simultaneous drying inside and out.

[0023] Furthermore, the drying oven 2 has slots 11 machined at both ends, and the closed door 4 is movably connected inside the slots 11. When the horizontal plate 7 moves the closed door 4, both ends of the closed door 4 will move along the inside of the slots 11. The slots 11 will limit the movement of the closed door 4, so that the closed door 4 remains stable when it moves.

[0024] Furthermore, the top of the drying oven 2 is fixedly connected to two guide rods 14, and the two sides of the horizontal plate 7 are fixedly connected to two limiting plates 15. The limiting plates 15 are movably connected to the outside of the guide rods 14, and the top of the guide rods 14 is fixedly connected to a top plate 13. The motor 5 is located on the top of the top plate 13.

[0025] When the horizontal plate 7 moves upward, the horizontal plate 7 will drive the limiting plate 15 to move upward. The limiting plate 15 will move along the outside of the guide rod 14. By providing the guide rod 14, the guide rod 14 will limit the movement of the limiting plate 15, thereby keeping the horizontal plate 7 in a stable state when it moves.

[0026] Furthermore, the top of the drying oven 2 is machined with multiple filter holes 12, which facilitate the discharge of water vapor generated inside the drying oven 2.

[0027] Working principle: When the masking paper base is conveyed into the drying chamber 2, the motor 5 is started. The motor 5 drives the threaded rod 6 to rotate, which in turn drives the horizontal plate 7 to move downward. The horizontal plate 7 then drives the sealing door 4 to move downward, closing both ends of the drying chamber 2 and sealing it. At the same time, the horizontal plate 7, through the connecting column 8, drives the fixing plate 9 and the infrared radiator 10 to move upward above the masking paper base. The infrared radiator 10 emits infrared rays. When the infrared rays irradiate the masking paper base, they are absorbed by the paper base and converted into heat energy, causing the moisture in the paper base to evaporate rapidly. Infrared rays have strong penetrating power and can penetrate deep into the interior of the paper base, achieving simultaneous drying inside and out.

[0028] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
