Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and more specifically, to a box dryer. Background Technology
[0002] In the packaging, warehousing and logistics industries, boxes (such as corrugated cardboard boxes and plastic turnover boxes) are commonly used carrying and packaging tools. During the production process (such as the bonding process of cardboard boxes and the injection molding and cooling process of plastic boxes) or after use (such as after getting damp or washing), moisture can easily remain on the surface or inside of these boxes. If the moisture is not removed in time, it will not only affect the structural strength of the box (such as cardboard boxes becoming soft and damaged when damp), but may also cause the packaged goods to become damp and deteriorate, or mold to grow during storage, affecting the safety and stability of the storage environment.
[0003] Existing box drying equipment has many shortcomings: the heating element layout of some dryers is unreasonable, resulting in uneven temperature distribution in the drying chamber, with some boxes being over-dried while others still retain moisture; the air supply mechanism of some equipment lacks filtration protection, allowing external dust and impurities to easily enter the equipment, affecting the service life of the fan and the drying effect; and some equipment has an improperly designed moisture discharge structure, which prevents the water vapor generated during drying from being discharged quickly, resulting in low drying efficiency.

[0009] Optionally, the louver blades are all designed to be tilted downwards at 35°-45°.
[0010] This invention utilizes four U-shaped electric heating tubes to form a rectangular heating frame, ensuring uniform temperature distribution within the drying chamber and consistent drying effects across all parts of the chamber, preventing localized dampness or over-drying. The air intake pipe of the air supply mechanism is equipped with sieve holes to filter impurities in the air, protecting the fan and ensuring a clean drying environment.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0017] like Figure 1-2 As shown, this utility model provides a box dryer, including: a base 1, a casing 2, a heating mechanism 3, an air supply mechanism 4, and a control mechanism 5; the casing 2 is installed on one side of the base 1; a drying chamber 6 is provided inside the casing 2; the heating mechanism 3 is installed inside the drying chamber 6; the air supply mechanism 4 is installed on the other side of the base 1; an air supply channel 7 is provided on one side of the casing 2; the air outlet of the air supply mechanism 4 is connected to the air inlet of the drying chamber 6 through the air supply channel 7; a louver 8 is provided on the other side of the casing 2; the louver 8 is connected to the air outlet of the drying chamber 6; the control mechanism 5 is installed on the top of the casing 2; the control mechanism 5 is electrically connected to the heating mechanism 3 and the air supply mechanism 4 respectively.
[0018] In this embodiment, as Figure 1-2As shown, the base 1 is made of stainless steel and welded together, providing a stable overall structure and serving as the supporting foundation for the entire equipment. The casing 2 is made of stainless steel plate and bent into shape. It is fixed to the left side of the base 1 with bolts. The front of the casing 2 can be equipped with an openable door (not shown in the figure) to facilitate the insertion and removal of the boxes to be dried. A sealing strip is installed between the door and the casing 2 to ensure the airtightness of the drying chamber 6. The drying chamber 6 has a rectangular cavity structure and is welded and fixed inside the casing 2. The air inlet of the drying chamber 6 is located on the side of the casing 2 near the air supply mechanism 4, and the air outlet is located on the other side of the casing 2. The control mechanism 5 controls the heating mechanism 3 and the air supply mechanism 4 in a unified manner. The temperature, wind speed and drying time can be preset to achieve automated operation and reduce the intensity of manual operation.
[0019] Furthermore, the air supply mechanism 4 includes: a fan 41 and an air intake pipe 42; the fan 41 is fixedly installed on the base 1; the air intake pipe 42 is fixedly connected to the fan 41 and communicates with the air inlet end of the fan 41; the air outlet end of the fan 41 is communicated with the air supply channel 7; the fan 41 is electrically connected to the control mechanism 5; a plurality of sieve holes 43 are provided on the air intake pipe 42; the diameter of the sieve holes 43 is 0.5cm-1.5cm.
[0020] In this embodiment, as Figure 1 As shown, four U-shaped heating tubes 31 are made of high-temperature resistant alloy material. The four U-shaped heating tubes 31 are fixed to the four corners of the inner side of the drying chamber 6 by bolts, forming a rectangular heating frame. The wiring ends of the heating tubes pass through the side wall of the drying chamber 6 and are electrically connected to the controller of the control mechanism 5. The wiring is sealed with a high-temperature resistant sealing sleeve to prevent air leakage. The rectangular heating frame formed by the four U-shaped heating tubes 31 ensures uniform temperature distribution in the drying chamber 6, ensuring consistent drying effect in all parts of the chamber and avoiding localized dampness or over-drying.
[0021] Furthermore, the control mechanism 5 includes: an electrical control cabinet 51 and a controller; the controller is installed inside the electrical control cabinet 51; the controller is electrically connected to the fan 41 and the heating mechanism 3 respectively.
[0022] In this embodiment, as Figure 1 As shown, the control mechanism 5 is installed on the top of the chassis 2. The electrical control cabinet 51 is made of cold-rolled steel plate and is fixed to the top of the chassis 2 with bolts. The controller is a PLC controller, which is fixedly installed inside the electrical control cabinet 51. The controller is electrically connected to the fan 41 and the U-shaped electric heating tube 31 through wires. An operation panel (not shown in the figure) is set on the outside of the electrical control cabinet 51. The operation panel is equipped with a power switch, a temperature adjustment knob, a fan speed adjustment knob and a time setting button, which facilitates the operator to set parameters.
[0023] Furthermore, the heating mechanism 3 includes: four U-shaped electric heating tubes 31; the four U-shaped electric heating tubes 31 are arranged around the inner side of the drying chamber 6 to form a rectangular heating frame; the electric heating tubes are electrically connected to the controller.
[0024] In this embodiment, as Figure 1-2 As shown, the fan 41 is fixed to the base 1 with bolts. The suction pipe 42 is made of PVC material, and one end is fixedly connected to the air inlet of the fan 41 through a flange. The body of the suction pipe 42 is uniformly stamped with several sieve holes 43, and the diameter of the sieve holes 43 is 1.0cm. The other end of the suction pipe 42 extends to the clean air area outside the equipment. The air supply channel 7 is made of stainless steel pipe. One end is sealed and welded to the air outlet of the fan 41, and the other end passes through the side wall of the casing 2 and is sealed and connected to the air inlet of the drying chamber 6 to ensure that there is no air leakage. The suction pipe 42 of the air supply mechanism 4 is equipped with sieve holes 43, which can filter impurities in the air, protect the fan 41 and ensure a clean drying environment. The sealed connection design between the fan 41 and the air supply channel 7 ensures directional airflow and improves air supply efficiency.
[0025] Furthermore, the blades of the louver 8 are all designed to be tilted downwards at 35°-45°.
[0026] In this embodiment, as Figure 2 As shown, the louver 8 is fixedly installed on the right side wall of the casing 2 (corresponding to the air outlet of the drying chamber 6) by bolts. The blades of the louver 8 are made of aluminum alloy and the downward tilt angle of the blades is set to 40°. The blades are connected by hinges and can automatically adjust the opening and closing angle with the airflow. The louver 8 adopts a downward tilt design of 35°-45°, which is conducive to the rapid discharge of water vapor and can also block the entry of external foreign objects, thus optimizing the drying environment.
[0027] In the specific implementation process, such as Figure 1-2As shown, the operator opens the front door of the machine casing 2, carefully places the boxes to be dried into the drying chamber 6, ensuring the boxes are in the center of the rectangular heating frame, closes the door, and locks it. Using the control panel on the outside of the electrical control cabinet 51, the operator sets the drying temperature (generally 40-80℃, depending on the box material and moisture content), airflow speed (low, medium, and high), and drying time (generally 30-120 minutes). The operator then turns on the power switch; after receiving the command, the controller controls the U-shaped heating mechanism 3. The electric heating element heats up when energized, simultaneously controlling the start of the fan 41. The fan 41 draws in outside air through the suction pipe 42. The air is filtered through the screen 43 to remove dust, particles, and other impurities before entering the fan 41. After being pressurized by the fan 41, the air is stably delivered into the drying chamber 6 through the air supply channel 7. The hot air in the drying chamber 6 comes into full contact with the boxes, absorbing moisture from the surface and inside of the boxes, forming humid and hot air carrying moisture. Under the pressure of the airflow, the humid and hot air flows from the air outlet of the drying chamber 6 to the louvers 8, pushing the louver blades of the louvers 8 to open and exhaust the air outside the equipment. After the set drying time is reached, the controller automatically controls the heating mechanism 3 and the fan 41 to stop working and issues a prompt sound. The operator can then turn off the power, open the chamber door, and remove the dried boxes.
[0028] This utility model discloses a box dryer. A rectangular heating frame is formed by four U-shaped electric heating tubes, ensuring uniform temperature distribution within the drying chamber and consistent drying effect across all parts of the box, preventing localized dampness or over-drying. The air intake pipe of the air supply mechanism is equipped with a sieve to filter impurities in the air, protecting the fan and ensuring a clean drying environment. The sealed connection design between the fan and the air supply channel ensures directional airflow and improves air supply efficiency. The louvers are designed with a 35°-45° downward tilt, facilitating rapid water vapor discharge while preventing the entry of external foreign objects, optimizing the drying environment. The control mechanism centrally controls the heating and air supply mechanisms, allowing preset temperature, wind speed, and drying time for automated operation and reduced manual labor intensity.
