Description

Technical Field

[0001] This utility model relates to a drying machine, and more particularly to a drying machine for nonwoven fabric processing, belonging to the technical field of nonwoven fabric processing equipment. Background Technology

[0002] Nonwoven fabrics possess numerous advantages such as moisture resistance, breathability, flexibility, and lightweight, and are widely used in various fields including medical, hygiene, agriculture, and industry. Drying is a crucial step in the production and processing of nonwoven fabrics, as its drying effect directly affects the final quality of the fabric, such as strength, breathability, and smoothness.

[0003] Currently, the existing nonwoven fabric dryers on the market have the following shortcomings during use: most dryers use a single hot air direct blowing method for drying, and the hot air is unevenly distributed in the drying chamber, resulting in inconsistent heating in different areas of the nonwoven fabric. This can easily lead to local over-drying or incomplete drying, affecting the stability of the nonwoven fabric quality.

[0004] Therefore, it is necessary to propose a drying machine for nonwoven fabric processing to solve the problems existing in the prior art. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this utility model provides a drying machine for nonwoven fabric processing, thereby solving the problem of poor drying uniformity in existing dryers.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a drying machine for non-woven fabric processing, including a housing, the housing comprising: A conveying mechanism is installed inside the box body. The conveying mechanism includes a drive roller, a driven roller, and a drive motor. The output shaft of the drive motor is connected to the drive roller, and the drive roller is connected to the driven roller. The drying mechanism installed above the conveying mechanism includes a heating component, a blower component, and a hot air distribution component. The hot air distribution component includes a main air duct connected to the blower component, an upper branch pipe and a lower branch pipe connected to the main air duct respectively. The upper branch pipe and the lower branch pipe are distributed above and below the conveying mechanism respectively. Several air outlets are opened on the pipe walls of the upper branch pipe and the lower branch pipe.

[0007] Preferably, the heating element is installed on the inner wall of the housing, and the heating element is an electric heating tube.

[0008] Preferably, the blower assembly includes a blower cavity formed inside the housing, a blower is provided at the top of the blower cavity, a base plate is provided at the bottom, and an upper branch pipe is installed on the bottom surface of the base plate.

[0009] Preferably, a mounting plate is provided below the conveying mechanism corresponding to the blower cavity, and a lower branch pipe is installed on the side of the mounting plate facing the driven roller, with the lower branch pipe and the driven roller being distributed alternately.

[0010] Preferably, the air outlets are inclined, with the air outlets of the upper branch pipe inclined toward the conveying direction of the conveying mechanism, and the air outlets of the lower branch pipe inclined away from the conveying direction of the conveying mechanism.

[0011] Preferably, the driving roller is installed at the feed end of the housing, and there are multiple driven rollers evenly distributed along the inner cavity of the housing.

[0012] Preferably, the output shaft of the drive motor is connected to the drive roller via a first belt, and the drive roller is connected to the driven roller via a second belt.

[0013] Preferably, the two driven rollers are connected by a second belt drive.

[0014] This utility model proposes a drying machine for non-woven fabric processing. By setting up a hot air distribution component, hot air is evenly distributed above and below the conveying mechanism, and inclined air outlets are opened on the branch air ducts, so that the hot air can be evenly applied to the upper and lower surfaces of the non-woven fabric. This effectively solves the problem of uneven drying caused by uneven hot air distribution in traditional dryers and ensures the stability of non-woven fabric quality. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1The drying equipment shown includes a housing 1, with a support 7 at the bottom of the housing 1. A feed inlet 11 is located on one side of the housing 1, and a discharge outlet 12 is located on the other side. The housing 1 includes: The conveying mechanism 2 is installed inside the box body. The conveying mechanism 2 includes a drive roller 21, a driven roller 22, and a drive motor 23. The output shaft of the drive motor 23 is connected to the drive roller, and the drive roller 21 is connected to the driven roller 22. The driving roller 21 is rotatably mounted at the feed end of the housing, and there are multiple driven rollers 22 evenly distributed along the inner cavity of the housing. The drive motor is mounted on a bracket; the output shaft of the drive motor 23 is connected to the driving roller via a first belt 24, and the driving roller 21 is connected to the driven roller via a second belt. Two driven rollers 22 are connected to each other via a second belt.

[0021] The conveying mechanism 2 is used to transport non-woven fabric. Specifically, the drive motor is started, which drives the active roller to rotate. The rotation of the active roller drives the adjacent driven roller to rotate. The adjacent driven rollers are driven by the No. 2 belt, so that each driven roller rotates synchronously with the active roller, thereby realizing the transport of non-woven fabric.

[0022] like Figure 2 As shown, the drying mechanism 3 is installed above the conveying mechanism. The drying mechanism 3 includes a heating component 5, a blower component 4, and a hot air distribution component 6. The hot air distribution component 6 includes a main air duct 61 connected to the blower component, an upper branch pipe 62 and a lower branch pipe 63 respectively connected to the main air duct. The upper branch pipe 62 and the lower branch pipe 63 are respectively distributed above and below the conveying mechanism. Several air outlets are opened on the pipe walls of the upper branch pipe and the lower branch pipe to ensure that the hot air is in full contact with the non-woven fabric.

[0023] By setting a drying mechanism inside the box and a hot air distribution component in the transport direction of the nonwoven fabric, the upper and lower branch pipes are evenly distributed above and below the nonwoven fabric, and the hot air is evenly distributed above and below the conveying mechanism, so that the hot air can come into more full contact with the surface of the nonwoven fabric, thereby improving the drying effect.

[0024] Preferably, a mounting plate 44 is provided below the conveying mechanism 2 corresponding to the blower cavity. A lower branch pipe 63 is installed on the side of the mounting plate 44 facing the driven roller, and the lower branch pipe 63 is staggered with the driven roller.

[0025] To facilitate the installation of the lower branch pipe, an installation plate is set below the conveying mechanism, and the lower branch pipe is installed on the installation plate. The lower branch pipe is set opposite to the upper branch pipe to ensure that the nonwoven fabric can be fully dried during the nonwoven fabric transportation process. Preferably, the upper and lower branch pipes are bent into a continuous U-shape, and the lower branch pipe is staggered with the driven roller to ensure that hot air can be blown onto the nonwoven fabric.

[0026] Preferably, the air outlets are inclined, with the air outlets of the upper branch pipe inclined toward the conveying direction of the conveying mechanism, and the air outlets of the lower branch pipe inclined away from the conveying direction of the conveying mechanism. By setting the inclination directions of the air outlets of the upper and lower branch pipes to be opposite, the hot air can come into more full contact with the surface of the nonwoven fabric, thereby further improving the drying effect.

[0027] Heating component 5 is installed on the inner wall of the chamber, and the heating component is an electric heating element. The electric heating element is electrically connected to an external power source. The heating component heats the air, and the hot air dries the non-woven fabric.

[0028] The blower assembly 4 includes a blower chamber 43 formed inside the housing. A blower 41 is mounted on the top of the blower chamber 4, and a base plate 42 is located at the bottom. An upper branch pipe is installed on the bottom surface of the base plate 42. Multiple U-shaped through holes are spaced apart on the base plate 42, and the upper branch pipes are staggered below the U-shaped through holes. An exhaust port is also provided on the top of the blower chamber, and an adjustable damper or valve is installed at the exhaust port. Preferably, a small induced draft fan can be installed at the exhaust port to force the humid air out of the housing, further improving the dehumidification speed.

[0029] Preferably, two sets of blowers are also installed on the inner wall of the air chamber 4. By installing blowers on the inner wall of the air chamber, forced airflow is achieved, which optimizes temperature distribution and accelerates moisture evaporation, ultimately improving drying efficiency and drying quality. The heating element is responsible for heating the air to the target temperature, and the blowers are responsible for delivering the hot air to all corners of the air chamber and expelling the humid air carrying moisture (partially through the exhaust port).

[0030] Furthermore, the inner wall of the enclosure is also equipped with an insulation layer made of rock wool insulation material, which can effectively reduce heat loss inside the enclosure and improve energy utilization.

[0031] In use, the nonwoven fabric to be dried enters the conveying mechanism inside the box through the feed inlet. The drive motor rotates the active roller, which in turn rotates the driven roller, thus conveying the nonwoven fabric. Simultaneously, the blower assembly draws in air, which is heated by the heating assembly to form hot air. This hot air enters the main air duct and is distributed to various branch pipes, then evenly blown onto the upper and lower surfaces of the nonwoven fabric through the air outlets. The dried nonwoven fabric is then output through the discharge outlet.

[0032] Example 2

[0033] The difference between this embodiment and Embodiment 1 is that: A feeding mechanism is provided at the inlet, and a discharging mechanism is provided at the outlet; one end of the conveying mechanism 2 is connected to the feeding mechanism, and the other end is connected to the discharging mechanism; Both the feeding mechanism and the discharging mechanism include a guide roller 13 and a tension roller 14, which are rotatably installed at the feed inlet and the discharge outlet to guide and tension the nonwoven fabric.

[0034] The conveying mechanism, together with the tension rollers in the feeding and discharging mechanisms, not only enables stable conveying of nonwoven fabric, but also tensions and smooths the nonwoven fabric, preventing wrinkles and shifts during the drying process, thus further improving product quality.

[0035] Preferably, a temperature sensor is installed inside the housing to detect the temperature inside the blower chamber. A controller is installed that is electrically connected to the temperature sensor and the heating component respectively. The controller can control the working status of the heating component according to the temperature signal detected by the temperature sensor.

[0036] The temperature sensor can monitor the temperature inside the chamber in real time and automatically adjust the working status of the heating components through the controller to achieve precise control of the drying temperature. It can be flexibly adjusted according to the drying needs of different types of non-woven fabrics, thus improving the applicability of the equipment.

[0037] The bottom of the chamber is also equipped with a dust collection drawer, which is slidably connected to the chamber to collect impurities and dust that fall off the non-woven fabric during the drying process, making it easy to clean later.

[0038] By setting up feeding and discharging mechanisms, during operation, the non-woven fabric to be dried is first guided and tensioned by the guide rollers and tensioning rollers at the feeding port, and then enters the conveying mechanism for conveying and drying. A temperature sensor monitors the temperature inside the chamber in real time and transmits the signal to the controller. The controller adjusts the power of the heating components according to the preset temperature value to achieve precise temperature control. After drying, the non-woven fabric is guided and tensioned by the discharging mechanism before being output. By tensioning and smoothing the non-woven fabric during conveying, problems such as wrinkles and shifting during the drying process are avoided, further improving product quality.

[0039] The purpose of this invention is to provide a drying machine for non-woven fabric processing. By setting a drying mechanism inside the housing, the hot air distribution components are evenly distributed above and below the non-woven fabric, allowing the hot air to be evenly distributed above and below the conveying mechanism. This ensures that the hot air can make more thorough contact with the surface of the non-woven fabric, ultimately improving the drying effect. By setting the conveying mechanism in conjunction with the tension rollers in the feeding and discharging mechanisms, not only can the stable conveying of the non-woven fabric be achieved, but it can also be tensioned and smoothed, preventing wrinkles and shifting of the non-woven fabric during the drying process, further improving product quality.

[0040] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
