Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a drying device for nonwoven fabric production. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is composed of oriented or random fibers and is named for its resemblance to cloth in appearance and some of its properties. It boasts advantages such as moisture resistance, breathability, flexibility, lightweight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, affordability, and recyclability. In production, it is primarily made from polypropylene granules through a continuous one-step process involving high-temperature melting, spinning, web formation, and hot-pressing. During the nonwoven fabric production process, the rolls removed from the forming equipment contain a certain amount of moisture and require drying to meet the requirements of subsequent processing and use.

[0003] In nonwoven fabric production, double-sided drying is often used to improve drying efficiency. To ensure the nonwoven fabric is completely dried, it is kept in the drying equipment for a relatively long time. However, although this operation can ensure that the nonwoven fabric is dried as a whole, due to the different heating conditions in different areas, the excessive time spent in the drying equipment will cause some areas of the nonwoven fabric to be over-dried. Over-drying will damage the fiber structure in the nonwoven fabric, weaken the bonding force between the fibers, and thus significantly reduce the key physical properties of the nonwoven fabric such as tensile strength and tear strength. This will affect the quality and performance of the nonwoven fabric and will be detrimental to subsequent processing and application.

[0004] Therefore, it is necessary to provide a drying device for nonwoven fabric production to solve the above-mentioned technical problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 7A drying device for nonwoven fabric production includes a protective shell 1, with inlets and outlets on both the left and right sides of the protective shell 1. A first air inlet pipe 11 is fixedly installed on the right side of the front side of the protective shell 1. The rear end of the first air inlet pipe 11 penetrates the inner wall of the front side of the protective shell 1. A drying cylinder 12 is fixedly installed at one end of the first air inlet pipe 1 that extends into the interior of the protective shell 1. A humidity detection component 2 is symmetrically fixedly installed on the inner wall of the rear side of the protective shell 1. A neutralizing drying chamber 3 is symmetrically slidably arranged inside the protective shell 1 and to the left of the humidity detection component 2. An exhaust port 31 is opened on the side of the neutralizing drying chamber 3 near the middle of the protective shell 1.

[0026] The rear inner wall of the protective shell 1 is vertically slidably equipped with a power mechanism for moving the neutralization and drying chamber 3. The power mechanism is fixedly installed with the neutralization and drying chamber 3.

[0027] The interior of the neutralizing and drying chamber 3 is equipped with a linearly arranged adjustment mechanism for adjusting the exhaust volume of the exhaust port 31. The adjustment mechanism is slidably engaged with the neutralizing and drying chamber 3.

[0028] In the specific implementation process, after the nonwoven fabric is initially dried by the drying cylinder 12, the moisture content is monitored by the humidity detection component 2. When the nonwoven fabric passes through the adjustment mechanisms on both sides, the power mechanism drives the adjustment mechanisms on both sides to move accordingly. The movement of the adjustment mechanisms changes the exhaust volume and exhaust distance, so that the drying device can achieve the drying effect of the nonwoven fabric while preventing over-drying. This leads to a significant improvement in the key physical properties of the nonwoven fabric, such as tensile strength and tear strength, thereby improving the quality and performance of the nonwoven fabric.

[0029] refer to Figure 4 and Figure 5 As shown, the power mechanism includes a vertical slot plate 4, a drive motor 41, a threaded rod 42, and a movable locking block 43. The vertical slot plate 4 is fixedly installed on the inner wall of the rear side of the protective shell 1. The drive motor 41 is fixedly installed on the top of the protective shell 1. The bottom end of the drive motor 41 penetrates the inner wall of the top of the protective shell 1 and extends into the vertical slot plate 4. The threaded rod 42 is fixedly installed on the output end of the drive motor 41 that extends into the vertical slot plate 4. The movable locking block 43 is threadedly connected to the outside of the threaded rod 42. The movable locking block 43 is slidably engaged with the vertical slot plate 4. The front end of the movable locking block 43 is fixedly installed with the neutralizing and drying chamber 3.

[0030] It should be noted that the neutralization and drying chamber 3 is moved by the coordination of the internal structure of the power mechanism.

[0031] refer to Figure 4 , Figure 6 and Figure 7As shown, the adjustment mechanism includes a power-assisting plate 51, a long strip plate 52, a frame plate 53, a sealing block 54, a fixing plate 55, and a power rod 57. A stabilizing slot 5 is provided on the top right side of the neutralizing drying chamber 3. The power-assisting plate 51 is slidably engaged inside the stabilizing slot 5. The long strip plate 52 is fixedly installed at the bottom end of the power-assisting plate 51. The frame plate 53 is linearly and evenly arranged and fixedly installed on the left side of the frame plate 53. The sealing block 54 is linearly and evenly arranged and fixedly installed on the inner walls of the front and rear sides of the frame plate 53. The fixing plate 55 is fixedly installed on the top of the power-assisting plate 51. An arc-shaped adjustment slot 56 is provided on the rear inner wall of the protective shell 1 and on the right side of the vertical slot plate 4.

[0032] The adjustment mechanism also includes a synchronization plate 61 and a second air inlet pipe 62. A synchronization slot 6 is provided on the left side of the front side of the protective shell 1. The synchronization plate 61 is slidably engaged in the synchronization slot 6. The second air inlet pipe 62 is fixedly installed on the front side of the synchronization plate 61. The rear end of the second air inlet pipe 62 passes through the rear side of the synchronization plate 61. One end of the second air inlet pipe 62 extending out of the rear side of the synchronization plate 61 is connected to the neutralization and drying chamber 3.

[0033] It should be noted that the exhaust volume of the exhaust port 31 is adjusted during the movement of the neutralizing and drying chamber 3 by adjusting the coordination of the internal structure of the adjustment mechanism.

[0034] refer to Figure 7 As shown, the diameter of the vent 31 is slightly smaller than the diameter of the sealing block 54.

[0035] It should be noted that the sealing block 54 can completely seal the exhaust port 31.

[0036] refer to Figure 7 As shown, a first storage slot is provided on the left inner wall of the stabilizing slot 5. A first baffle is slidably engaged in the first storage slot. The right end of the first baffle is fixedly installed on the left side of the assisting slot 51.

[0037] It should be noted that when the assist plate 51 moves, it drives the first baffle to move and simultaneously seal the stabilizing slot 5, thereby reducing the leakage of heat.

[0038] refer to Figure 6 As shown, a second storage slot is provided on the top inner wall of the synchronization slot 6. A second baffle is slidably engaged in the second storage slot, and the bottom end of the second baffle is fixedly installed with the top of the synchronization plate 61.

[0039] It should be noted that: when the synchronization plate 61 moves, it drives the second baffle to move and synchronously seal the synchronization slot 6, thereby reducing the amount of hot air flowing to the outside of the protective shell 1.

[0040] The working principle of the drying device for nonwoven fabric production provided by this utility model is as follows: During use, the first air inlet pipe 11 and the second air inlet pipe 62 are connected to an external hot air conveying device. When drying the nonwoven fabric is required, the nonwoven fabric enters the protective shell 1 from the right side and passes through the drying cylinder 12 in an S-shape. The drying cylinder 12 sprays hot air to dry the nonwoven fabric. After passing through the drying cylinder 12, the nonwoven fabric continues to move to the left, passing through the humidity detection component 2. The humidity detection component 2 detects the nearly dried nonwoven fabric. When the remaining moisture in this section of the nonwoven fabric is too low, it transmits the data to the service department. The terminal sends a command to the drive motor 41, which drives the threaded rod 42 to rotate a certain number of times. Under the constraint of the vertical slot plate 4, the threaded rod 42 drives the moving block 43 to move upwards. The moving block 43 drives the neutralizing and drying chamber 3 to move upwards. The neutralizing and drying chamber 3 drives the assisting plate 51 to move upwards. The assisting plate 51, through the long strip plate 52 and the frame plate 53, drives the sealing block 54 to move synchronously. The assisting plate 51 drives the fixing plate 55 to move upwards. The fixing plate 55 drives the power rod 57 to move upwards. The power rod 57 moves along the arc-shaped adjusting slot 5. During the upward movement of plate 6, the fixed plate 55 moves to the left, which in turn moves the long strip plate 52 to the left. The long strip plate 52, through multiple frame plates 53, moves its corresponding sealing block 54 a certain distance to the left. The distance the sealing block 54 moves to the left partially blocks the exhaust port 31, thereby reducing the exhaust volume of the exhaust port 31. At the same time, the neutralizing drying chamber 3 moves the second air inlet pipe 62 upward synchronously, and the second air inlet pipe 62 moves the synchronous clamping plate 61 upward synchronously along the synchronous clamping groove 6. Similarly, the bottom neutralizing drying chamber 3 and the exhaust port 3... The downward movement works on the same principle as above, causing the exhaust vents 31 on both sides to reduce the exhaust volume during the movement, thereby weakening the drying of the nonwoven fabric. Similarly, when there is too much residual moisture in this section of the nonwoven fabric, the neutralizing drying chamber 3 on both sides and the exhaust vents 31 increase the exhaust volume during the movement to strengthen the drying of the nonwoven fabric. The principle is the same as above, so that the drying device can achieve the drying effect of the nonwoven fabric while preventing over-drying of the nonwoven fabric. This leads to a significant improvement in the key physical properties of the nonwoven fabric, such as tensile strength and tear strength, thereby improving the quality and performance of the nonwoven fabric and facilitating subsequent processing and application.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
