Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric drying technology, specifically a drying device for nonwoven fabrics. Background Technology

[0002] Non-woven fabric is made from chemical fibers and plant fibers on wet or dry papermaking machines under conditions where water or air is used as a suspension medium. Although it is a cloth, it is not woven, hence the name non-woven fabric. Non-woven fabric is a new generation of environmentally friendly material with advantages such as high strength, breathability and waterproofness, environmental friendliness, flexibility, non-toxicity and odorlessness, and low price. Non-woven fabric generally needs to be dried using drying equipment during the production process.

[0003] Existing drying equipment for nonwoven fabrics generally has a fixed height for the hot air outlet. As a result, when the moisture content of the nonwoven fabric to be dried varies, the height of the hot air outlet cannot be effectively adjusted according to the actual situation, leading to a relatively poor drying effect for the nonwoven fabric. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of 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.

[0024] Please see Figures 1 to 3 This utility model provides a technical solution: a drying device for non-woven fabrics, including a drying box 1, an adjusting drying component 200 for drying is installed inside the drying box 1, and an extrusion component 300 for extrusion is installed inside the drying box 1.

[0025] By using the drying chamber 1, the air outlet 202, the regulating cylinder 205, the storage box 209, and the extrusion assembly 300 in the adjusting drying component 200, the height of the hot air outlet can be effectively adjusted according to the required moisture content of the nonwoven fabric to be dried, so that the distance between the air outlet and the nonwoven fabric is the optimal distance, thereby improving the drying effect of the nonwoven fabric. Furthermore, by using both extrusion and drying methods to dry the nonwoven fabric, the moisture content of the nonwoven fabric is more easily controlled, thus enabling the nonwoven fabric to meet higher product standards.

[0026] In this embodiment, the adjusting drying component 200 is a structure for drying nonwoven fabric.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the adjustable drying assembly 200 includes a hot air blower body 201 fixed to the top of the drying chamber 1. An air outlet pipe 202 is fixed to the air outlet end of the hot air blower body 201. A motor 203 is fixed to the top of the drying chamber 1. A screw 204 is fixed to the output shaft of the motor 203. An adjusting cylinder 205 is threadedly connected to the outside of the screw 204. A limit plate 206 is fixed to the right side of the adjusting cylinder 205. A limit rod 207 is slidably connected inside the limit plate 206. Two baffles 208 are fixed to the outside of the limit rod 207. A storage box 209 is fixed to the bottom of the adjusting cylinder 205. Multiple air outlet pipes 210 are fixed to the bottom and both sides of the storage box 209. Hot air is delivered to the surface of the non-woven fabric through the multiple air outlet pipes 210, which can achieve a better drying effect.

[0028] It should be noted that the adjustable distance between the bottom of the limiting plate 206 and the top of the bottom baffle 208 is less than the adjustable distance of the screw 204 in the adjusting cylinder 205. In conjunction with the two baffles 208, it effectively prevents the screw 204 from falling off the adjusting cylinder 205 during the adjustment process. The front of the drying oven 1 is hinged with a door to ensure convenient cleaning and maintenance of the interior of the drying oven 1 in the future.

[0029] In addition, the bottom end of the limiting rod 207 is fixed to the top of the storage box 209. The limiting rod 207 is fixed in place. The side of the air outlet pipe 202 away from the hot air blower body 201 passes through the drying box 1 and the storage box 209 in sequence and extends into the interior of the storage box 209, ensuring that the air outlet pipe 202 can deliver the hot air generated by the hot air blower body 201 to the storage box 209.

[0030] In addition, there are through holes 4 on both the left and right sides of the drying chamber 1 to ensure that the non-woven fabric can be placed into the drying chamber 1 through the through holes 4. Inside the drying chamber 1, three rollers 5 are rotatably connected by bearings. The non-woven fabric body 6 is slidably connected between the outer sides of the three rollers 5 to ensure that the non-woven fabric body 6 is more stable under the action of the rollers 5 and to increase the contact time between the non-woven fabric body 6 and the hot air, thereby achieving the expected drying effect.

[0031] In this embodiment, the extrusion assembly 300 is a structure for extruding nonwoven fabric.

[0032] like Figure 1 As shown, the extrusion assembly 300 includes a horizontal plate 301 fixed to the left side wall inside the drying chamber 1. An electric push rod 302 is fixed to the bottom of the horizontal plate 301. A mounting frame 303 is fixed to the bottom end of the electric push rod 302. A first extrusion roller 304 is rotatably connected inside the mounting frame 303 via a bearing. A second extrusion roller 305 is rotatably connected inside the drying chamber 1 via a bearing.

[0033] It should be noted that the nonwoven fabric body 6 is slidably connected to the outside of the second extrusion roller 305, ensuring that the nonwoven fabric body 6 can be squeezed by the first extrusion roller 304 and the second extrusion roller 305, thereby squeezing out the water in the nonwoven fabric body 6, which facilitates subsequent drying.

[0034] The working principle of the above embodiments is as follows:

[0035] In use, the nonwoven fabric to be dried is passed through the through hole 4 into the drying chamber 1 and the three rollers 5. Then, the motor 203 is turned on, driving the screw 204 to rotate in place. Under the limiting action of the internal thread rotation thrust and the limiting plate 206 and the limiting rod 207, the adjusting cylinder 205 moves up and down on the outside of the screw 204, thereby driving the storage box 209 and the air outlet pipe 210 to move up and down, so that the air outlet pipe 210 can be adjusted to the specified height. Then, the hot air blower body 201 is turned on, and hot air is delivered to the storage box 209 through the air outlet pipe 202. Then, hot air is sprayed out through the air outlet pipe 210 to dry the nonwoven fabric body 6. At the same time, the electric push rod 302 is turned on, driving the mounting frame 303 and the first extrusion roller 304 to move up and down. Thus, through the cooperation of the first extrusion roller 304 and the second extrusion roller 305, the nonwoven fabric body 6 is extruded. Thus, by using both extrusion and drying methods, the drying efficiency of the nonwoven fabric body 6 is improved.

[0036] Compared with existing technologies, this nonwoven fabric drying equipment, through the coordinated use of the drying chamber 1, the air outlet 202 in the adjusting drying component 200, the adjusting cylinder 205, the storage box 209, and the extrusion component 300, can effectively adjust the height of the hot air blower outlet according to the required moisture content of the nonwoven fabric to be dried, thereby achieving the optimal distance between the air outlet and the nonwoven fabric, thus improving the drying effect of the nonwoven fabric. Furthermore, by using both extrusion and drying methods to dry the nonwoven fabric, the moisture content in the nonwoven fabric is more easily controlled, enabling the nonwoven fabric to meet higher product standards and solving the problem of the relatively poor drying effect of existing nonwoven fabric drying equipment.

[0037] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The provision of external power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
