Description

Technical Field

[0001] This utility model relates to the field of paper tube drying technology, and more specifically to a drying chamber for wrapped film paper tubes. Background Technology

[0002] As a key carrier in the production and storage of stretch film, the dryness of the paper tube directly affects the smoothness of the roll-up, storage stability, and subsequent reliability of the stretch film. Currently, the industry mostly uses traditional drying equipment for drying stretch film paper tubes. This type of equipment often cannot implement differentiated drying control for different areas within the drying chamber, resulting in uneven heating and inconsistent drying levels. Furthermore, the drying process relies on real-time manual monitoring and adjustment, which is heavily influenced by the operator's experience. Combined with variations in the initial moisture content of the paper tubes, these factors can easily lead to under-drying or over-drying, affecting product quality consistency and increasing production costs. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of existing stretch film paper tube drying equipment, such as the inability to distinguish the regional drying efficiency, high dependence on manual intervention, and poor consistency of drying effect. It provides a drying chamber for stretch film paper tubes to achieve an efficient, uniform, and controllable drying process and improve the stability of paper tube drying quality.

[0004] To achieve the above objectives, this utility model provides a drying chamber for wound film paper tubes, comprising a base, a chamber body, a heating unit, and a control unit. The base is a hollow structure, and a plurality of ventilation holes are provided on the upper surface of the base along the arrangement direction of the paper tubes. The chamber body is disposed on the base, and a plurality of air outlets are provided at intervals on the top of the chamber body. The chamber body is provided with a door. The heating unit includes a fan and heating elements. The fan is disposed on the base, and a plurality of heating elements are provided. Each of the ventilation holes has a heating element at its air outlet end. The control unit includes a connected temperature and humidity sensor and a processor. A plurality of temperature and humidity sensors are provided, and the temperature and humidity sensors are disposed on the side of the air outlets. The processor is disposed on the base.

[0005] Preferably, the inner corners of the base are rounded.

[0006] Preferably, the inner wall of the chamber is coated with a heat-insulating coating.

[0007] Preferably, the base has a detachable weight block at its bottom.

[0008] Preferably, the periphery of the air outlet is recessed towards the air inlet.

[0011] Preferably, the alarm module is configured as a photoelectric alarm.

[0012] Preferably, a loading ramp is provided on the base on the side of the cargo door.

[0013] The above technical solution constructs a closed-loop controllable drying system by incorporating a hollow base with ventilation holes, a chamber equipped with air outlets and a door, a heating unit containing a fan and heating elements, and a control unit consisting of temperature and humidity sensors and a processor. This system utilizes a fan to drive airflow through the heating elements to form hot air, which is then evenly delivered into the chamber through the ventilation holes and discharged through the air outlets, forming a directional circulation. Multiple temperature and humidity sensors positioned on the side of the air outlets monitor the chamber environment in real time and feed the data back to the processor.

[0016] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0017] As mentioned above, this utility model provides a drying chamber for wound film paper tubes, including a base 1, a chamber body 2, a heating unit, and a control unit. The base 1 is a hollow structure, and a plurality of ventilation holes 11 arranged along the paper tube arrangement direction are provided on the upper surface of the base 1. The chamber body 2 is mounted on the base 1, and a plurality of air outlet holes 21 are spaced apart on the top of the chamber body 2. The chamber body 2 is provided with a chamber door 22. The heating unit includes a fan 3 and heating elements. The fan 3 is mounted on the base 1, and a plurality of heating elements are provided. Each of the ventilation holes 11 has a heating element at its air outlet end. The control unit includes a connected temperature and humidity sensor 4 and a processor 5. A plurality of temperature and humidity sensors 4 are provided, and the temperature and humidity sensors 4 are located on the side of the air outlet holes 21. The processor 5 is mounted on the base 1. It should be emphasized that the function of the fan 3 is to apply pressure to the base 1, so that a pressure difference exists between the base 1 and the chamber body 2. This forces the airflow into the chamber, creating a pressure difference between the chamber 2 and the outside environment. The device features a hollow base 1 with ventilation holes 11 along the paper tube arrangement direction, an air outlet 21 at the top of the chamber 2 with a door 22, several heating elements at the air outlet of the ventilation holes 11, and a fan 3. Multiple temperature and humidity sensors 4 are also arranged on the side of the air outlet 21. The processor 5 controls the heating unit to achieve uniform airflow to the wrapped film paper tubes, precise temperature and humidity control, improved drying efficiency and quality, and consistent drying effect. It should be noted that the controller itself does not control the power of each heating element 6, but those skilled in the art can connect the controller to the logic circuit to control the power of each parallel heating element 6. Furthermore, all electrical appliances and power supplies are electrically connected via wires. The specific connection method can be achieved by those skilled in the art based on the component connection method within the device; the circuit connection method will not be elaborated here.

[0018] In one specific embodiment, the base 1 is a hollow structure with an integrally formed air guide cavity inside. The corners of the cavity are rounded to reduce convection when the fan 3 blows air. The inner wall of the cavity is coated with a heat insulation coating to reduce energy loss. The upper surface of the base 1 has several ventilation holes 11 spaced apart along the conventional paper tube arrangement direction. An electric heating wire 6 is installed at the ventilation hole 11. The electric heating wire 6 can control the heat generation by adjusting the current and control the temperature of the paper tube by the data obtained from the temperature and humidity sensor 4. It should be noted that the heat insulation coating is not specifically limited in this application. It is mainly to avoid the increase in production costs caused by heat exchange between the space to be heated inside the device and the outside. For example, the heat insulation coating can be set as an aerogel heat insulation coating, a waterproof heat insulation coating, etc. Furthermore, a mesh mat can also be laid on the upper surface of the base 1, which can facilitate the movement of the drying rack with the moving device without hindering the passage of the heating airflow.

[0019] In this utility model, a detachable load-bearing block is provided at the bottom of the base 1, and a loading ramp 8 is provided on the base 1 on the side of the door 22. This design is to lower the center of gravity of the device and further improve the stability of the device. The device of this application is lightweight and easy to transport. The detachable load-bearing block can be transported in parts during transportation, reducing the construction pressure of installation. The loading ramp 8 is designed to facilitate the convenient transportation of drying racks, etc. In this process, the load-bearing block can also provide the function of increasing the friction at the bottom.

[0020] According to a technical solution provided by this utility model, the periphery of the air outlet 21 is recessed towards the inlet of the ventilation hole 11. This design is to make the temperature and humidity sensor 4 near the air outlet 21 more accurate, especially the humidity parameter. Direct air outlet will cause the humidity parameter to be seriously inconsistent with the actual humidity. Recessing the part of the outlet near the inner cavity can make the airflow stay here to improve the accuracy of the measurement.

[0021] In one specific embodiment, the processor 5 is connected to an alarm module, which is mounted on the base 1. The alarm module is configured as a photoelectric alarm 7. The alarm module can effectively reduce the occurrence of safety accidents or reduce the losses caused by safety accidents. It should be noted that the photoelectric sensor in this embodiment is only one option for an alarm module and is not specifically limited to it. For example, auditory sensors such as buzzers can also achieve the warning effect.

[0022] Working Principle: When the equipment is started, the fan 3 on the outside of the base 1 operates, drawing in outside air and pressurizing it into the hollow cavity of the base 1. The upper surface of the base 1 has evenly distributed ventilation holes 11 along the paper tube arrangement direction, each corresponding to a heating element. Under the pressure of the fan 3, ambient temperature airflow converges towards each ventilation hole 11, making full contact with the heating elements to form hot air. Driven by the airflow pressure, the hot air is ejected vertically upwards from the ventilation holes 11, evenly covering the interior of the chamber 2. A paper tube drying rack, commonly used in paper tube drying, can be directly placed inside the chamber 2. Subsequently, the hot air contacts the paper tubes and carries away the humid, hot airflow formed by the evaporation of moisture from the paper tubes. This hot air is then directionally guided out of the chamber 2 by the air outlet 21 at the top of the chamber 2. During this process, the heating elements and ventilation holes 11 are evenly distributed along the paper tube arrangement direction, ensuring that paper tubes in different positions within the chamber receive hot airflow, avoiding uneven heating in certain areas. The hot air transfers heat to the paper tubes through convection, and the continuously circulating airflow carries away moisture from the paper tubes. Simultaneously, the inner wall of the chamber 2 is insulated... The thermal coating also reduces heat loss to maintain a stable high-temperature environment inside the chamber and improve moisture evaporation efficiency. The temperature and humidity sensor 4 inside the air outlet 21 at the top of the chamber 2 transmits the real-time temperature and humidity data to the processor 5 inside the base 1. The processor 5 controls the heating unit by comparing the data. When the temperature is lower than the target, it controls the heating element to increase its power and maintains the stable operation of the fan 3 to ensure the supply of hot air. When the temperature is higher than the target, it reduces the power of the working heating element or reduces the speed of the fan 3 to reduce the input of hot air. When the humidity is higher than the target, it keeps the heating element and the fan 3 working normally to accelerate dehumidification. After the humidity reaches the target, it first turns off the heating element and then lets the fan 3 continue to run for a period of time to expel the residual hot and humid airflow inside the chamber. If the temperature and humidity greatly exceed the set range, such as in case of unexplained high temperature, the processor 5 will trigger the alarm module to sound an alarm. Finally, the paper tube dehumidification is completed by directional airflow circulation, which achieves uniform air delivery and efficient heat transfer. The autonomous feedback regulation ensures the drying quality and safety. The three work together to achieve efficient, uniform and precise drying of the wrapping film paper tubes.

Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
