Description

Technical Field

[0001] This utility model relates to the field of wrapping material processing technology, specifically a constant temperature and humidity chamber for wrapping paper processing. Background Technology

[0002] Paper wrapping is a key process in the production of insulating or protective materials for electrical and cable industries. It aims to process raw paper into wrapping materials with specific strength and insulation. The process includes raw paper screening, slitting, impregnation, drying and shaping, and winding. It is necessary to control the paper tension and impregnation uniformity to ensure that the thickness deviation of the finished product is reduced and the temperature resistance meets the standards. The finished product has the characteristics of insulation, wear resistance and easy winding. It is widely used for cable core wrapping and motor coil insulation layers. It is an important basic material to ensure the safe operation of electrical equipment. The environment for paper wrapping needs to be kept at constant temperature and humidity.

[0003] In existing constant temperature and humidity chambers, such as the one described in application number 201922423807.7, the technical solution includes a chamber body comprising a main frame assembled from welded square tube modules and flame-retardant, heat-insulating, and sound-absorbing protective panels embedded in the main frame. An air inlet is located on one side of the chamber body, with an intake fan at the inlet. An exhaust outlet is located on the top of the chamber body, with an exhaust fan at the exhaust outlet. The chamber also includes a temperature and humidity regulating device installed within the chamber body, an entrance / exit door equipped with an electrically controlled safety lock, and a control module connected to the temperature and humidity regulating device. However, existing constant temperature and humidity chambers lack sufficient humidity control precision. Using traditional steam humidification or electrode-type humidification, they cannot meet the high-precision humidity requirements of wrapping paper, and the humidification area is concentrated, resulting in uneven humidity distribution within the chamber.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing constant temperature and humidity chamber. Utility Model Content

[0006] The purpose of this invention is to provide a constant temperature and humidity chamber for paper wrapping processing, so as to solve the problems of insufficient humidity control accuracy and poor atomization uniformity mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A constant temperature and humidity chamber for paper wrapping processing includes a chamber structure. The chamber structure has a double door on the front side, with a viewing window above the double door. A control cabinet is located on the left side of the chamber structure. Several ventilation systems are installed inside the chamber structure. A thermometer and hygrometer are installed on the outside of the chamber structure and electrically connected to the control cabinet. An intelligent ultrasonic atomizer is installed on the outside of the chamber structure, with an atomizing pipe connected above the intelligent ultrasonic atomizer. The atomizing pipe is distributed on three sides inside the chamber structure, and each atomizing pipe outlet is equipped with an atomizing nozzle.

[0009] Preferably, a fan is fixedly installed on the top of the building structure, and a ventilation system is installed below the fan via connecting pipes, and the ventilation system is distributed inside the building structure.

[0010] Using the above technical solution, the fan at the top of the room structure drives the ventilation system through the connecting pipe, which can increase the air circulation rate inside the room. Combined with the distributed layout of the ventilation system inside the room, it avoids the accumulation of local temperature and humidity, ensures that the environment of each area of ​​the wrapping paper is consistent during the processing, and prevents the paper from curling or having different strengths due to uneven local humidity.

[0011] Preferably, the surface of the thermometer and hygrometer is provided with a display screen, and buttons are provided below the display screen.

[0012] Using the above technical solution, the display screen on the surface of the thermometer and hygrometer can display the indoor temperature and humidity data in real time, making it convenient for operators to intuitively monitor environmental parameters. The buttons below the display screen support manual calibration and parameter setting, avoiding control errors caused by deviations in the thermometer and hygrometer data, and providing accurate environmental data references for the processing of wrapping paper.

[0013] Preferably, a humidity buffer tank is provided on the outside of the chamber structure, and the humidity buffer tank is connected to the intelligent ultrasonic atomizer through a pipe.

[0014] Using the above technical solution, the humidity buffer tank on the outside of the chamber structure is connected to the intelligent ultrasonic atomizer through a pipe. It can store the moisture generated by the atomizer and quickly replenish the moisture when the humidity in the chamber drops suddenly, avoiding humidity fluctuations caused by frequent start-stop of the intelligent ultrasonic atomizer and ensuring stable humidity in the paper wrapping processing environment.

[0015] Preferably, a filter box is provided above the intelligent ultrasonic atomizer, and a filter screen is provided inside the filter box, and the atomizing pipe is connected to the top of the filter screen.

[0016] Using the above technical solution, the filter box above the intelligent ultrasonic atomizer is equipped with a filter screen, which can filter impurities and scale in the atomized moisture, prevent impurities from adhering to the wrapping paper through the atomization pipe and atomization nozzle, avoid affecting the paper's insulation performance and surface flatness, and ensure processing quality.

[0017] Preferably, a feed pipe is provided above the filter box, and a descaling agent is added inside the feed pipe to clean the filter screen.

[0018] Using the above technical solution, descaling agent can be added to the filter box through the feeding pipe above the filter box. The filter screen can be cleaned without disassembling the filter box, avoiding the decrease in atomization caused by scale blockage. This ensures continuous and stable humidification supply to the intelligent ultrasonic atomizer and reduces equipment maintenance downtime.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the constant temperature and humidity chamber for processing the wrapping paper,

[0020] 1. Precise and uniform humidity control to ensure the quality of wrapping paper processing: The moisture generated by the intelligent ultrasonic atomizer is filtered by the filter box and then humidified without dead angles through the atomizing pipes and atomizing nozzles distributed on three sides of the chamber structure; combined with the humidity buffer tank to stabilize the humidity, the humidity control accuracy can reach ±1%RH, solving the problems of uneven humidification and insufficient accuracy of traditional equipment, avoiding defects such as curling and reduced strength of wrapping paper due to humidity deviation, and improving the finished product qualification rate;

[0021] 2. Efficient circulation and convenient monitoring enhance equipment practicality and stability: The fan-driven distributed ventilation system at the top of the chamber structure enables rapid air circulation within the chamber, ensuring uniform temperature and humidity. The display screen of the thermometer and hygrometer provides real-time visual monitoring, and the buttons allow for convenient calibration. Combined with the linkage control of the control cabinet, operators can monitor and adjust environmental parameters in real time, reducing the frequency of manual inspections and preventing production interruptions caused by equipment parameter malfunctions, thus improving processing continuity.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution:

[0030] A constant temperature and humidity chamber for paper wrapping processing includes a chamber structure 1, a double door 2 on the front side of the chamber structure 1, a viewing window 3 above the double door 2, a control cabinet 4 on the left side of the chamber structure 1, several ventilation systems inside the chamber structure 1, a thermometer and hygrometer 6 on the outside of the chamber structure 1 and electrically connected to the control cabinet 4, an intelligent ultrasonic atomizer 7 on the outside of the chamber structure 1, and an atomizing pipe 12 connected above the intelligent ultrasonic atomizer 7. The atomizing pipe 12 is distributed on three sides inside the chamber structure 1, and each outlet end of the atomizing pipe 12 is equipped with an atomizing nozzle 13.

[0031] A fan 5 is fixedly installed on the top of the chamber structure 1, and a ventilation system is installed below the fan 5 through connecting pipes. The ventilation system is distributed inside the chamber structure 1. The fan 5 on the top of the chamber structure 1 drives the ventilation system through the connecting pipes, which can increase the air circulation rate inside the chamber. With the distributed layout of the ventilation system inside the chamber, local temperature and humidity accumulation is avoided, ensuring that the environment of each area of ​​the wrapping paper is consistent during the processing, and preventing the paper from curling or having different strengths due to uneven local humidity.

[0032] The thermometer and hygrometer 6 has a display screen 61 on its surface and a button 62 below the display screen 61. The display screen 61 on the surface of the thermometer and hygrometer 6 can display the indoor temperature and humidity data in real time, which makes it convenient for operators to intuitively monitor environmental parameters. The button 62 below the display screen 61 supports manual calibration and parameter setting, avoiding control errors caused by the deviation of the thermometer and hygrometer 6 data, and providing accurate environmental data reference for the processing of wrapping paper.

[0033] A humidity buffer tank 8 is installed on the outside of the chamber structure 1, and the humidity buffer tank 8 is connected to the intelligent ultrasonic atomizer 7 via a pipe. A filter box 10 is installed above the intelligent ultrasonic atomizer 7, and a filter screen is installed inside the filter box 10. An atomization pipe 12 is connected to the top of the filter screen. A feed pipe 11 is installed above the filter box 10, and a descaling agent is added inside the feed pipe 11 to clean the filter screen. The humidity buffer tank 8 on the outside of the chamber structure 1 is connected to the intelligent ultrasonic atomizer 7 via a pipe, and can store the moisture generated by the atomizer. When the humidity in the chamber drops suddenly, the moisture is quickly replenished, avoiding frequent start-stop of the intelligent ultrasonic atomizer 7. To mitigate humidity fluctuations and ensure stable humidity levels in the wrapping paper processing environment, the filter box 10 above the intelligent ultrasonic atomizer 7 is equipped with a filter screen. This screen filters impurities and scale from the atomized moisture, preventing impurities from adhering to the wrapping paper via the atomization pipe 12 and atomization nozzle 13. This avoids affecting the paper's insulation performance and surface smoothness, ensuring processing quality. The feeding pipe 11 above the filter box 10 allows for the addition of descaling agent, enabling cleaning of the filter screen without disassembling the filter box 10. This prevents a decrease in atomization volume due to scale blockage, ensuring a continuous and stable humidity supply from the intelligent ultrasonic atomizer 7 and reducing equipment maintenance downtime.

[0034] Working principle:

[0035] When using this utility model,

[0036] Environmental monitoring and command triggering: The temperature and humidity meter 6 collects the temperature and humidity data inside the room structure 1 in real time and displays it on the display screen 61. After the data is transmitted to the control cabinet 4, if the humidity is lower than the set threshold, the control cabinet 4 triggers the intelligent ultrasonic atomizer 7 to start. If the humidity is higher than the threshold, the fan 5 is started to enhance ventilation and dehumidification.

[0037] Humidification and humidity stabilization process: After the intelligent ultrasonic atomizer 7 is started, the generated moisture first enters the filter box 10, where impurities are filtered through the internal filter screen. Part of the filtered moisture enters the humidity buffer tank 8 for storage and stabilization, while the other part is transported through the atomization pipe 12 to the three sides of the chamber structure 1, where it is evenly sprayed into the chamber by the atomizing nozzle 13. When the humidity in the chamber approaches the set threshold, the control cabinet 4 adjusts the output power of the atomizer, and the humidity buffer tank 8 releases the stored moisture simultaneously to avoid sudden changes in humidity.

[0038] Ventilation and cleaning maintenance: Fan 5 runs continuously, driving the ventilation system through connecting pipes to circulate the air in the room and ensure uniform temperature and humidity distribution. When the filter screen in the filter box 10 shows signs of blockage, descaling agent is added through the feeding pipe 11 to clean the filter screen online and ensure smooth moisture delivery. Operators can observe the processing situation in the room through the viewing window 3 on the double door 2 and grasp the production status without opening the door.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
