Therefore, it is particularly important to improve existing pre-humidification equipment for polyester fabric processing and design a new type of pre-humidification equipment to address the aforementioned technical shortcomings and enhance the overall practicality of pre-humidification equipment for polyester fabric processing.

[0004] The purpose of this utility model is to provide a pre-humidification device for processing polyester fabric. This pre-humidification device can fully and evenly humidify the fabric multiple times, with fast humidification speed and good effect. It ensures the aesthetics while facilitating subsequent processing. At the same time, it keeps the fabric in a taut state, which facilitates uniform humidification, saves water resources, and improves the overall practicality of the pre-humidification device for processing polyester fabric, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pre-humidification device for processing polyester fabric includes a main body. Inside the main body, a first rotating roller and a second rotating roller are rotatably connected and arranged side by side. Inside the main body and at the top of the first rotating roller and the second rotating roller, a first pressing roller designed to be tangential to them is rotatably connected. At the bottom of the first rotating roller and the second rotating roller, two sets of oppositely distributed atomizing nozzles are fixedly connected. At the bottom of the atomizing nozzles and between the first rotating roller and the second rotating roller, an infrared humidity sensor is fixedly connected.

[0007] As a preferred embodiment of this utility model, limit grooves are provided on both sides of the interior of the main body and at the bottom of the infrared humidity sensor.

[0008] As a preferred embodiment of this utility model, the two sets of rotating wheels are connected by a synchronous belt, and the drive end of a motor is fixedly connected to the bottom of one set of rotating wheels and located inside the main body.

[0009] As a preferred embodiment of this utility model, both sets of threaded rods are provided with connecting blocks on their outer sides and inside the limiting grooves. The two sets of connecting blocks are rotatably connected by a tension adjusting roller and a second pressing roller. The tension adjusting roller and the second pressing roller are designed to be parallel and tangent to each other.

[0010] As a preferred embodiment of this utility model, an inclined plate is slidably connected inside the main body and at the bottom of the second pressing roller, and a horizontal plate is fixedly connected to the side of the inclined plate near the second pressing roller and inside the main body, and a plurality of equally spaced through holes are fixedly connected to the top of the horizontal plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-3 This utility model provides a technical solution:

[0024] A pre-humidification device for processing polyester fabric includes a main body 1. Inside the main body 1, a first rotating roller 801 and a second rotating roller 802 are rotatably connected and arranged side-by-side. Inside the main body 1, at the top of both the first rotating roller 801 and the second rotating roller 802, a first pressing roller 8 tangentially designed to be connected to them is rotatably connected. At the bottom of both the first rotating roller 801 and the second rotating roller 802, two sets of oppositely distributed atomizing nozzles 7 are fixedly connected. At the bottom of each atomizing nozzle 7, between the first rotating roller 801 and the second rotating roller 802, an infrared humidity sensor 701 is fixedly connected. When the pre-humidification device for processing polyester fabric is put into use, the power is turned on, and the polyester fabric enters the interior of the main body 1, first passing between the first rotating roller 801 and the first pressing roller 8, from... The polyester fabric is smoothed out for easier subsequent humidification before entering the space between two opposing sets of atomizing nozzles 7 at the bottom of the first rotating roller 801, thus achieving double-sided humidification for more even humidification. The small water droplets sprayed from the atomizing nozzles 7 penetrate the polyester fabric more easily, preventing water from directly accumulating and sliding down, resulting in good humidification. The infrared humidity sensor 701 detects the humidification effect of the polyester fabric. Based on the detection results, when the polyester fabric enters the space between the two opposing sets of atomizing nozzles 7 at the bottom of the second rotating roller 802, it undergoes supplementary humidification based on the results of the infrared humidity sensor 701, ensuring sufficient and even humidification and improving humidification quality. The polyester fabric is then smoothed out between the second rotating roller 802 and the first pressing roller 8, ensuring aesthetics and facilitating subsequent processing.

[0025] Furthermore, limit grooves 101 are provided on both sides of the main body 1 and at the bottom of the infrared humidity sensor 701. Threaded rods 603 are rotatably connected inside both sets of limit grooves 101. Rotating wheels 601 are fixedly connected to the bottom of both sets of threaded rods 603 and inside the main body 1. The two sets of rotating wheels 601 are connected by a synchronous belt 602. The drive end of a motor 6 is fixedly connected to the bottom of one set of rotating wheels 601 and inside the main body 1. Connecting blocks 502 are provided on the outer sides of both sets of threaded rods 603 and inside the limit grooves 101. The two sets of connecting blocks 502 are rotatably connected by a tension adjusting roller 5 and a second pressing roller 501. The tension adjusting roller 5 and the second pressing roller 501 are designed to be parallel and tangential. When the pre-humidification equipment for polyester fabric processing is put into use and the power is turned on, the tension adjusting roller 5 and the first rotating roller 801... Both the first and second rotating rollers 802 are tangentially designed. The fabric moves from the first rotating roller 801 to between the tension adjusting roller 5 and the second pressing roller 501, then around to the bottom of the tension adjusting roller 5 and to the top of the second rotating roller 802. The fabric is squeezed between the tension adjusting roller 5 and the second pressing roller 501, thus deeply combining with the water and improving the humidification effect. The drive end of the motor 6 rotates, thereby driving the rotating wheel 601 to rotate, which in turn drives the synchronous belt 602 to rotate, which in turn drives another set of rotating wheels 601 to rotate, which in turn drives the two sets of threaded rods 603 to rotate synchronously, which in turn drives the two sets of connecting blocks 502 to move synchronously. This allows the tension adjusting roller 5 to move in a timely manner according to the different fabrics and humidification conditions, so that the fabric is always kept taut, which facilitates humidification and avoids different humidification effects due to different fabric angles, further ensuring uniform humidification of the fabric.

[0026] The main body 1 has an inclined plate 2 slidably connected to the bottom of the second pressing roller 501. A horizontal plate 201 is fixedly connected to the side of the inclined plate 2 near the second pressing roller 501 and inside the main body 1. Multiple sets of equally spaced through holes 202 are fixedly connected to the top of the horizontal plate 201. A water collection box 3 is slidably connected to the bottom of the inclined plate 2. A filter box 301 is slidably connected to the side of the water collection box 3 near the limiting groove 101 and at the bottom of the inclined plate 2. A water tank 4 is located on the side of the filter box 301 away from the water collection box 3 and at the bottom of the inclined plate 2. A water pump 401 is located inside the water tank 4. Multiple sets of equally spaced heating rods 402 are fixedly connected to the end of the water tank 4 away from the filter box 301. When the polyester fabric is processed... When the humidifier is put into use, the power is turned on, the water tank 4 is connected to the external water pipe, the water pump 401 draws water from the water tank 4, and the water pump 401 is connected to multiple sets of atomizing nozzles 7 through water pipes. The heating rod 402 heats the water in the water tank 4, which can raise the water temperature to a suitable temperature for contact with the fabric, making the humidification speed faster and the effect better. The water collection box 3, the filter box 301 and the water tank 4 are interconnected. The excess water generated by humidification in the main body 1 slides down the inclined plate 2 onto the horizontal plate 201, and then enters the water collection box 3 through the through hole 202. After entering the filter box 301, it is cleaned and then enters the water tank 4 for reuse, saving water resources. The water collection box 3 and the filter box 301 can be pulled out from the side for easy cleaning and replacement of the filter element.

[0027] In this embodiment, the specific implementation scenario is as follows: In actual use, when the pre-humidification equipment for processing polyester fabric is put into use, the power is turned on, and the fabric first passes between the first rotating roller 801 and the first pressing roller 8, thereby smoothing the polyester fabric for subsequent humidification. Then, it enters between the two opposing sets of atomizing nozzles 7 at the bottom of the first rotating roller 801. The water pump 401 draws water from the water tank 4, and the water pump 401's outlet is connected to the multiple sets of atomizing nozzles 7 through water pipes. The heating rod 402 heats the water in the water tank 4, raising the water temperature to a suitable temperature for bonding with the fabric, resulting in faster humidification and better effect. This process ensures double-sided humidification of the fabric, resulting in more even humidification. The small water droplets sprayed from the atomizing nozzle 7 penetrate the polyester fabric more easily, preventing water from directly accumulating and slipping off, thus improving the humidification effect. The infrared humidity sensor 701 detects the humidification effect on the polyester fabric. The fabric then enters between the tension adjusting roller 5 and the second pressing roller 501, and then moves around to the bottom of the tension adjusting roller 5 to between the second rotating roller 802 and the first pressing roller 8. The fabric is squeezed between the tension adjusting roller 5 and the second pressing roller 501, thus deeply binding with the water and improving the humidification effect. The drive end of the motor 6 rotates, thereby driving the rotating wheel 601 to rotate, which in turn drives... The synchronous belt 602 rotates, thereby driving another set of rotating wheels 601 to rotate, which in turn drives two sets of threaded rods 603 to rotate synchronously, thereby driving two sets of connecting blocks 502 to move synchronously. This allows the tension adjusting roller 5 to move in a timely manner according to the different fabrics and humidification conditions, thus keeping the fabric in a taut state, facilitating humidification, avoiding uneven humidification effects due to different fabric angles, and further ensuring uniform humidification of the fabric. When it enters between the two opposing sets of atomizing nozzles 7 at the bottom of the second rotating roller 802, it performs supplementary humidification based on the result of the infrared humidity sensor 701, ensuring sufficient and uniform humidification. The improved humidification quality allows the humidifier to enter between the second rotating roller 802 and the first pressing roller 8, where it is smoothed out, ensuring aesthetics and facilitating subsequent processing. Excess water generated during humidification within the main body 1 slides down the inclined plate 2 onto the horizontal plate 201, then enters the water collection box 3 through the through hole 202, and finally enters the filter box 301 to be cleaned before entering the water tank 4 for reuse, saving water resources. The water collection box 3 and the filter box 301 can be pulled out from the side for easy cleaning and filter replacement. Compared with existing pre-humidification equipment for polyester fabric processing, this utility model improves the overall practicality of pre-humidification equipment for polyester fabric processing through its design.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
