[0002] Spunlace nonwoven fabric is produced by spraying high-pressure micro-jet water onto one or more layers of fiber web, causing the fibers to entangle and thus strengthening the web to a certain strength. The resulting fabric is called spunlace nonwoven fabric. During the production process, the nonwoven fabric after the spunlace process contains a large amount of moisture and needs to be dried to meet the requirements of subsequent processing and use.
[0003] Existing spunlace nonwoven fabric drying equipment has some shortcomings in practical use. For example, the drying efficiency is low, which cannot meet the needs of large-scale production; the drying is uneven, which easily leads to some areas of the nonwoven fabric being over-dried while others are under-dried, affecting product quality; and the energy consumption is high, increasing production costs. In addition, some drying equipment has an unreasonable structural design, making maintenance and cleaning inconvenient and reducing the service life of the equipment. Therefore, it is necessary to design a new spunlace nonwoven fabric drying equipment. Summary of the Invention

[0029] Please see Figures 1-3 This utility model discloses a spunlace nonwoven fabric drying device, including a drying box 1, a conveying mechanism and a heating mechanism;
[0030] Support feet 2 are installed at the bottom of the drying chamber 1;
[0031] The drying chamber 1 has a feed inlet 3 on one side and a discharge outlet 4 on the other side. Both the feed inlet and the discharge outlet are equipped with sealing curtains to reduce heat loss inside the drying chamber.
[0032] The conveying mechanism is installed inside the drying chamber 1 and is used to convey spunlace nonwoven fabric. The conveying mechanism includes a drive roller 5, a driven roller 6, and a conveyor belt 7. The drive roller 5 and the driven roller 6 are respectively installed at both ends of the drying chamber 1. The conveyor belt 7 is sleeved on the drive roller 5 and the driven roller 6. The mechanism also includes a drive motor 8. The motor shaft of the drive motor 8 is connected to the drive roller 5 for transmission. The drive roller is driven by the drive motor, which can drive the conveyor belt to rotate at a uniform speed, thereby conveying the spunlace nonwoven fabric from the feed port to the discharge port.
[0033] The heating mechanism is located inside the drying chamber, above and below the conveyor belt.
[0034] In this utility model, the heating mechanism includes a first heating tube assembly 9, a first reflector 10, a first mounting bracket 11, a second heating tube assembly 12, a second reflector 13, and a second mounting bracket 14. The first heating tube assembly 9 is installed above the conveyor belt 7, and both ends of the first heating tube assembly 9 are respectively connected to the inner sidewall of the drying chamber 1. The first reflector 10 is disposed above the first heating tube assembly 9, and the first reflector 10 is connected to the inner top wall of the drying chamber 1 through the first mounting bracket 11. The second heating tube assembly 12 is installed below the conveyor belt 7, and both ends of the second heating tube assembly 12 are respectively connected to the inner sidewall of the drying chamber 1. The second reflector 13 is disposed below the second heating tube assembly 12, and the second reflector 13 is connected to the inner bottom wall of the drying chamber 1 through the second mounting bracket 14. The first heating tube assembly 9 and the second heating tube assembly 12 are electrically connected to a temperature controller 15 installed on the outer wall of the drying chamber 1. The first and second heating tube groups generate heat, which is then transferred to a reflector. The reflector reflects the heat generated by the heating tube groups onto the spunlace nonwoven fabric, improving heating efficiency.
[0035] This utility model also includes a ventilation mechanism installed inside the drying chamber 1. The ventilation mechanism includes an air inlet 16, an air outlet 17, and a fan 18. The air inlet 16 is located at the bottom of the drying chamber 1, the air outlet 17 is located at the top of the drying chamber 1, and the fan 18 is installed at the air inlet 16, with the air inlet end of the fan 18 connected to the air inlet 16. This mechanism allows cold outside air to be introduced into the drying chamber, where it exchanges heat with the spunlace nonwoven fabric before being expelled from the drying chamber. Through the action of the ventilation mechanism, the air circulation speed inside the drying chamber is accelerated, improving drying efficiency.
[0036] In addition, a temperature sensor 19 and a humidity sensor 20 are installed on the inner wall of the drying chamber 1, respectively, to monitor the temperature and humidity inside the drying chamber in real time. A control panel 21 is also installed on the outer wall of the drying chamber 1. A touch screen display 22 is installed on the surface of the control panel 21, and a controller 23 is installed inside the control panel 21. The controller 23 is connected to the temperature sensor 19, the humidity sensor 20, the drive motor 8, the temperature controller 15, and the fan 18. The controller automatically adjusts the operating parameters of the heating mechanism and the ventilation mechanism according to the signals fed back by the temperature sensor and the humidity sensor to ensure that the temperature and humidity inside the drying chamber are always at the optimal state.
[0037] Working Principle: First, the spunlace nonwoven fabric is fed into the conveyor mechanism through the inlet and transported to the drying chamber via a conveyor belt. The heating elements in the heating mechanism then activate, heating and drying the spunlace nonwoven fabric. Simultaneously, the ventilation mechanism starts, with a fan drawing in cool outside air through the air inlet. This air exchanges heat with the spunlace nonwoven fabric before being expelled through the air outlet. Temperature and humidity sensors monitor the temperature and humidity inside the drying chamber in real time and send signals back to the controller. The controller automatically adjusts the operating parameters of the heating and ventilation mechanisms based on the feedback signals, ensuring that the temperature and humidity inside the drying chamber remain optimal. After drying, the spunlace nonwoven fabric is discharged from the outlet, completing the drying process.
[0038] In summary, this utility model has a novel structural design that enables all-around heating of spunlace nonwoven fabric and accelerates the air circulation speed inside the drying chamber, thereby improving drying efficiency and meeting the needs of large-scale production.
