Description

Technical Field

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

[0002] Non-woven fabric, also known as non-woven cloth, is a type of fabric made without spinning or weaving. Instead, it's made by arranging short or long textile fibers in a directional or random pattern to form a web structure, which is then reinforced using mechanical, thermal, or chemical methods. It lacks warp and weft threads, making cutting and sewing very convenient. It is lightweight, easy to shape, and possesses characteristics such as moisture resistance, breathability, flexibility, light weight, flame retardancy, non-toxicity, odorlessness, low price, and recyclability. It is widely used in medical and health, clothing, home decoration, industry, agriculture, and many other fields. The raw materials used in the production of non-woven fabrics are diverse. Polypropylene is the most commonly used raw material for non-woven fabrics, offering advantages such as chemical resistance and heat resistance; polyester fiber has strong tensile strength and high-temperature resistance; and polylactic acid is a biodegradable and environmentally friendly material with promising development prospects.

[0003] Drying nonwoven fabric raw materials before use is essential because they easily absorb water molecules during storage. If not effectively removed, the evaporation of moisture during high-temperature processing can cause defects such as holes and unevenness in the finished nonwoven fabric, and also weaken its strength. However, existing drying methods have many problems. For example, in traditional hot air drying, the hot airflow is obstructed in the particle accumulation, resulting in uneven drying and low efficiency. Moreover, after drying, larger particles may be mixed with other raw materials and flow out, affecting subsequent processing and product quality.

[0004] Therefore, in order to address the existing problem of uneven drying, a drying device for raw materials used in nonwoven fabric production is needed to solve the aforementioned problem. Summary of the Invention

[0005] To address the problem of uneven drying in existing technologies, this application provides a drying device for raw materials used in non-woven fabric production. A first motor drives a spline sleeve to rotate, which in turn drives a stirring rod to rotate synchronously. Simultaneously, a sliding rod on the outer wall of the stirring rod slides into the groove on the inner wall of the limiting tube, causing the stirring rod to rotate and move up and down repeatedly, thereby preventing the accumulation of raw materials. Furthermore, multiple heating tubes on the inner wall of the drying tank ensure more uniform heating of the raw materials, effectively reducing local overheating or undried conditions and significantly improving drying efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A drying device for raw materials used in nonwoven fabric production includes a drying tank. A control panel is fixedly connected to the front of the drying tank. Multiple heating tubes are arranged on the inner wall of the drying tank. A tank cover is fixedly connected to the top of the drying tank. A feed pipe is fixedly connected to the top of the tank cover. A limit tube is fixedly connected to the inner wall of the tank cover. A stirring rod is connected to the inner wall of the limit tube via a rotating assembly. Multiple stirring blades are fixedly connected to the outer wall of the stirring rod. A discharge pipe is fixedly connected to the bottom of the drying tank. A connecting shell is slidably connected to the front of the discharge pipe. Two semi-rings are fixedly connected to the top of the connecting shell. A filter tube is slidably connected to the outer wall of the two semi-rings. The front end of the filter tube is connected to the front of the discharge pipe via an adjusting assembly to rotate the filter tube.

[0007] As a further improvement of this utility model, the rotating assembly includes a spline sleeve rotatably connected to the inner wall of the limiting tube, the inner wall of the limiting tube is provided with an undulating groove, a connecting rod is fixedly connected to the top of the stirring rod, and a sliding rod is fixedly connected to the outer wall of the stirring rod.

[0008] As a further improvement of this utility model, the outer wall of the slide rod is slidably connected to the inner wall of the undulating groove, and the outer wall of the connecting rod is slidably connected to the inner wall of the spline sleeve.

[0009] As a further improvement of this utility model, a first motor is fixedly connected to the top of the can lid, and the drive end of the first motor is fixedly connected to the top of the spline sleeve.

[0010] As a further improvement of this utility model, a plurality of balls are rotatably connected to the outside of the slide rod, and a sealing ring is fixedly connected to the outer wall of the limiting tube.

[0011] As a further improvement of this utility model, the adjusting component includes a first gear fixedly connected to the front side of the filter tube, and a second gear rotatably connected to the front side of the discharge tube, wherein the outer wall of the second gear meshes with the outer wall of the first gear.

[0012] As a further improvement of this utility model, a plug rod is fixedly connected to the rear side of the inner wall of the discharge pipe, the front side of the plug rod is inserted into the rear end of the filter pipe, a second motor is fixedly connected to the front side of the discharge pipe, and the drive end of the second motor is fixedly connected to the front side of the second gear.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: In this invention, the first motor drives the spline sleeve to rotate, which in turn drives the stirring rod to rotate synchronously. At the same time, the sliding rod on the outer wall of the stirring rod slides and engages with the undulating groove on the inner wall of the limiting tube, causing the stirring rod to drive the stirring blades to rotate and move up and down repeatedly, thereby preventing the raw materials from accumulating. In addition, multiple heating tubes on the inner wall of the drying tank make the raw materials heat more evenly, effectively reducing local overheating or undried conditions, and greatly improving the drying efficiency.

[0014] In this invention, the dried raw material enters the filter tube through the discharge pipe. The second motor drives the gear transmission to rotate the filter tube, accelerating the discharge of raw material that meets the particle size requirements through the filter holes and retaining large particles. The filter tube is slidably connected to the discharge pipe through a semi-ring and a connecting shell. After drying, the connecting shell and discharge pipe can be easily pulled out to collect and process the retained large particles, preventing them from mixing with qualified raw material and affecting subsequent processing, thus ensuring the quality of the finished nonwoven fabric.

Specifically, the drying tank 1 provides a closed space for drying raw materials. The control panel 4 on its front side can set parameters such as heating temperature and stirring frequency. Multiple heating tubes 7 on the inner wall are the heat source, providing the required temperature for drying. The tank cover 2 on the top of the drying tank 1 serves as a seal. The feed pipe on the top of the tank cover 2 is used to inject raw materials. The spline sleeve 21 is rotatably connected to the inner wall of the limiting tube 8. The first motor 3 on the top of the tank cover 2 drives it to rotate. The stirring rod 10 is slidably connected to the spline sleeve 21 through the connecting rod 13 on the top and can rotate with the spline sleeve 21. The sliding rod 12 on its outer wall slides and engages with the undulating groove 14 on the inner wall of the limiting tube 8, allowing the stirring rod 10 to move up and down reciprocally. The ball bearings of the sliding rod 12 can reduce sliding friction, and the sealing ring 15 on the outer wall of the limiting tube 8 ensures the airtightness of the device. Example

[0024] refer to Figures 1-5 A discharge pipe 9 is fixedly connected to the bottom of the drying tank 1. A connecting shell 17 is slidably connected to the front side of the discharge pipe 9. Two semi-rings 19 are fixedly connected to the top of the connecting shell 17. A filter pipe 18 is slidably connected to the outer wall of the two semi-rings 19. A first gear 6 is fixedly connected to the front side of the filter pipe 18. A second gear 16 is rotatably connected to the front side of the discharge pipe 9. The outer wall of the second gear 16 meshes with the outer wall of the first gear 6. An insertion rod 20 is fixedly connected to the rear side of the inner wall of the discharge pipe 9. The front side of the insertion rod 20 is inserted into the rear end of the filter pipe 18. A second motor 5 is fixedly connected to the front side of the discharge pipe 9. The drive end of the second motor 5 is fixedly connected to the front side of the second gear 16.

[0025] Specifically, the discharge pipe 9 at the bottom of the drying tank 1 is the channel for raw material discharge. The connecting shell 17 slidably connected to its front side supports and limits the filter tube 18 through the two half-rings 19 fixed at the top, while allowing the filter tube 18 to slide and be disassembled. The filter tube 18 is used to screen raw materials. The first gear 6 on the front side meshes with the second gear 16 rotatably connected to the front side of the discharge pipe 9. The second motor 5 on the front side of the discharge pipe 9 drives the second gear 16 to rotate, which can drive the filter tube 18 to rotate to improve screening efficiency. The insertion rod 20 on the rear side of the inner wall of the discharge pipe 9 is inserted into the rear end of the filter tube 18 to further ensure the stability of the filter tube 18 during operation.

[0026] Working principle: At the start of operation, the operator slowly injects the non-woven fabric production raw materials into the drying tank 1 through the feed pipe at the top of the tank lid 2. Then, through the control panel 4 on the front side of the drying tank 1, the heating temperature and stirring frequency are set, and the multiple heating tubes 7 on the inner wall and the first motor 3 at the top of the tank lid 2 are started simultaneously. The first motor 3 drives the spline sleeve 21 on the inner wall of the limiting tube 8 to rotate. The spline sleeve 21, through sliding engagement with the connecting rod 13, drives the connecting rod 13 and the stirring rod 10 connected to the bottom to rotate synchronously. The sliding rod 12 on the outer wall of the stirring rod 10 rotates accordingly, and the sliding rod 12 slides in the undulating groove 14 on the inner wall of the limiting tube 8. Due to the undulating structure of the undulating groove 14, the stirring rod 10 drives the multiple stirring blades 11 on the outer wall to rotate and stir the raw materials while moving up and down repeatedly, fully breaking up the raw material clumps. Combined with the heat released by the heating tubes 7, the raw materials are dried evenly, avoiding local overheating or undried conditions.

[0027] During discharge, the dried raw material falls into the discharge pipe 9 at the bottom of the drying tank 1 and further enters the filter pipe 18 that cooperates with the discharge pipe 9. Then, the second motor 5 on the front side of the discharge pipe 9 is started. The second motor 5 drives the second gear 16 to rotate. The second gear 16 meshes with the first gear 6 on the front side of the filter pipe 18, driving the filter pipe 18 to rotate stably under the limit of the two half rings 19. During the rotation, small particles of raw material that meet the particle size requirements are discharged through the filter holes of the filter pipe 18, while large particles of raw material are intercepted. After the drying operation is completely finished, the worker slides the connecting shell 17, which is fixed to the half ring 19, out along the front side of the discharge pipe 9, taking out the connecting shell 17 and the discharge pipe 18 at the same time, and collects the intercepted large particles of raw material for subsequent crushing and reuse.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
