Description

Technical Field

[0001] This utility model relates to the technical field of paperboard drying equipment for cardboard production, and in particular to a drying equipment for paperboard production. Background Technology

[0002] Cardboard is a lightweight and inexpensive composite material made of corrugated paper core and linerboard layers. It has good support properties and is used as a packaging and logistics environmental protection carrier. Its multi-layer structure requires stable drying support. This demand has led to the development of high-efficiency hot air drying equipment. It penetrates the wet layer of cardboard with uniform and high-speed air delivery to quickly evaporate moisture. It is a key piece of equipment for improving the production line.

[0003] Traditional paperboard drying equipment relies on hot air directly contacting the paperboard surface to heat it through heat conduction, evaporating internal moisture and completing the drying process. However, in actual use, these devices suffer from high energy consumption, uneven heat distribution leading to unstable drying quality, and issues such as surface shrinkage, bubbling, warping, and other problems. Existing optimized paperboard drying equipment operates by using a fan to drive circulating hot air, creating a temperature gradient inside the drying chamber. The high-temperature airflow exchanges heat with the paperboard to remove moisture. However, current devices generally lack an independent and efficient moisture drying mechanism, failing to effectively remove and treat the large amount of evaporated water vapor carried in the hot air. This lack of a crucial structure causes the hot air inside the device to quickly reach saturation, severely limiting drying efficiency and significantly extending drying time. Furthermore, the continuously high humidity environment causes long-term corrosion of electrical components and metal structures inside the drying chamber, affecting operational stability, reducing equipment lifespan, and increasing maintenance costs. Therefore, this paperboard drying device is proposed to address these problems. Utility Model Content

Then, put the cardboard to be heated in and release it to complete the fixing and clamping action.

[0036] Specifically, the fixing mechanism 5 includes a second fixing plate 501, with a heating chamber 1 mounted on its outer wall. A spindle 502 is fixedly connected to the inner wall of the second fixing plate 501. A spring 503 is fixedly connected to the bottom of the outer wall of the second fixing plate 501.

After placing the cardboard to be heated, the lifting knob 504 is released, and the rebound force of the spring 503 drives the vulcanized silicone 506 to reset, clamping the cardboard for stable fixation. The soft properties of the vulcanized silicone 506 ensure that the cardboard surface is not damaged during the clamping process. The heat from the heating chamber 1 is transferred through the fixing mechanism 5, promoting cardboard processing efficiency. The entire operation is simple and quick, requiring only manual control of the lifting knob 504 to complete the clamping and releasing cycle. The design of the fixing mechanism 5 optimizes the cardboard heating process and improves the overall practicality of the equipment.

[0037] Reference Figure 1 , Figure 2 and Figure 4Two fixing blocks 6 are fixedly connected to the front side of the outer wall of the heating chamber 1, which are used to fix the pull rod 7 to ensure its stability. The pull rod 7 is fixedly connected to the adjacent side of the outer wall of the two fixing blocks 6, which facilitates the opening and closing of the heating chamber 1. The outer wall of the heating chamber 1 is rotatably connected to the chamber cover 8. The top of the outer wall of the chamber cover 8 is provided with multiple exhaust ports 9, which are used to release the internal air pressure and ensure the normal operation of the equipment. The bottom of the outer wall of the box cover 3062 is fixedly connected to the top of the outer wall of the dehumidification box 301. The bottom of the inner wall of the dehumidification box 301 is fixedly connected to the first fixing plate 304.

[0038] Specifically, two fixing blocks 6 are provided on the front side of the outer wall of the heating chamber 1. The main function of the fixing blocks 6 is to fix the pull rod 7, ensure the reliable operation of the pull rod 7, and maintain the stability of the components. The two fixing blocks 6 are equipped with pull rods 7 on one side close to each other. The pull rods 7 make it easy for users to open and close the heating chamber 1, and the operation is easy and quick. The outer wall of the heating chamber 1 is connected to the chamber cover 8, which can be rotated to open and close. Multiple exhaust ports 9 are arranged on the top of the outer wall of the chamber cover 8. The exhaust ports 9 are responsible for releasing the excess air pressure generated inside the heating chamber 1, preventing pressure accumulation, and ensuring the safety of the equipment during normal operation. As for the dehumidification box 301, the bottom of the outer wall of the box cover 3062 is directly fixed to the top of the outer wall of the dehumidification box 301, and the two are firmly connected. The bottom of the inner wall of the dehumidification box 301 is fixed with a first fixing plate 304, which provides stable support and positioning for the internal components.

[0039] Working principle: First, the dehumidification box 301 is responsible for collecting and containing the moisture carried by the hot and humid air in the heating chamber 1. The bottom of this component is firmly connected to the top of the crossbeam 2. A fixing groove 302 is opened on the rear side of the outer wall of the dehumidification box 301. An axial flow fan 305 is installed in the groove to ensure its stable operation. A drying plate 303 is fixed to the bottom of the inner wall of the dehumidification box 301. It continuously absorbs moisture from the air through adsorption, effectively reducing the ambient humidity. The outer wall of the drying plate 303 is firmly positioned by the first fixing plate 304 to maintain its long-term and reliable function. The axial flow fan 305 is configured on the inner wall of the fixing groove 302. The fan 305 actively draws in the humid air in the heating chamber 1 and guides the airflow to continuously enter the dehumidification box 301, forming a moisture treatment circulation system. The top of the dehumidification box 301 is equipped with a sealing component 306, which includes a magnetic strip 3061 and a box cover 3062. The bottom of the magnetic strip 3061 is fixed to the top of the dehumidification box 301, and the top is fixed to the box cover 3062. The magnetic force is used to achieve convenient opening and closing and sealing, providing an operation channel for replacing the drying plate 303. The entire mechanism systematically completes the collection and absorption of moisture through the combination of adsorption and forced airflow, significantly improving the humidity regulation effect.

[0040] Furthermore, when the user pulls the lifting knob 504 vertically, it causes the spindle 502 to compress the spring 503, causing the vulcanized silicone 506 to rise and separate from the surface of the heating chamber 1, creating a placement space. Then, the cardboard to be processed is placed in. When the lifting knob 504 is released, the spring 503 releases its rebound force, pushing the vulcanized silicone 506 back to its original position and adhere to the surface of the cardboard. The vulcanized silicone 506 applies pressure evenly due to its elastic properties, forming a stable clamping effect. During this process, the two ends of the spindle 502 are linked to the lifting knob 504 and the base 505 respectively. The top of the vulcanized silicone 506 is fixed to the bottom of the base 505. During clamping, the soft contact surface of the vulcanized silicone 506 completely covers the edge of the cardboard, ensuring both clamping firmness and avoiding pressure marks on the material surface. The entire operation is completed by lifting and releasing with one hand, greatly simplifying the traditional clamping process. The heat resistance of the vulcanized silicone 506 ensures that it maintains its elastic properties in high-temperature environments. The mechanism utilizes the synergistic effect of mechanical elasticity and flexible materials to achieve efficient clamping.
