Description

Technical Field

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

[0002] Nonwoven fabric, as a new type of environmentally friendly material composed of oriented or randomly arranged fibers, has advantages such as moisture resistance, breathability, light weight and recyclability. It is widely used in medical, packaging, industrial and other fields. In its production and processing, in order to ensure the stability of product performance and avoid mold or deformation, it is necessary to remove residual moisture between fibers through professional drying equipment to improve the quality of finished products and storage safety.

[0003] For example, the nonwoven fabric drying mechanism disclosed in Chinese Patent No. CN218034246U involves nonwoven fabric entering the drying chamber through a conveyor channel. The rotation of a drive wheel propels the nonwoven fabric into the chamber, where it moves around the drying device. The drying device dries the fabric by outputting airflow, and the dried fabric is then output through a conveyor channel on the other side, thus achieving the drying purpose. Since the drive wheel's rotation drives the fabric, the drive structure is simple. Furthermore, the entire drying device is built into the drying chamber, minimizing external influences and ensuring stable and efficient drying. However, while the drying mechanism in the aforementioned patent can dry nonwoven fabric, it only provides airflow from one side. This results in the windward side of the fabric being overheated, while the leeward side suffers from insufficient heat penetration, creating a "low-temperature, wet zone." This temperature difference can cause unidirectional shrinkage stress in the nonwoven fabric, leading to wavy deformation and affecting the drying quality and effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution: a non-woven fabric drying mechanism, including a drying box, with inlets and outlets on the left and right sides of the drying box, and inlets at a high position and outlets at a low position. The inner rear wall of the drying box has multiple connecting ports with a right-high-left-low orientation. Multiple conveying rollers are rotatably arranged on the inner front and rear walls of the drying box with a right-high-left-low orientation. The interior of the connecting port is symmetrically and slidably equipped with an air supply mechanism for both-sided air supply and adjustable air supply spacing.

[0005] As an improvement to the above technical solution, the air supply mechanism includes a fixed square frame plate, an air supply square frame pipe, a partition plate, a synchronous motor, a bidirectional screw, a power locking block, and a drying assembly. The fixed square frame plate is fixedly installed on the rear side of the drying chamber and located outside the communication port. The air supply square frame pipe is fixedly installed on the inner wall of the fixed square frame plate. The partition plate is fixedly installed on the inner wall of the air supply square frame pipe near the front end. The front side of the partition plate has symmetrically arranged diversion ports. The inner walls of the left and right sides of the air supply square frame pipe, located on the front side of the partition plate, have vertical locking slots. The synchronous motor is symmetrically fixedly installed on the top of the fixed square frame plate. The bottom end of the synchronous motor penetrates the top inner wall of the vertical locking slot. The bidirectional screw is fixedly installed on the output end of the synchronous motor that extends into the vertical locking slot. The power locking block is threadedly connected to the outside of the bidirectional screw and slidably engages with the vertical locking slot. The drying assembly is fixedly located at the end of the power locking block away from the vertical locking slot.

[0006] As an improvement to the above technical solution, the drying component includes a diversion air guide box and a vent. The diversion air guide box is fixedly installed at the end of the power block away from the vertical slot. The vent is fixedly installed on the outside of the diversion air guide box close to the rear end. The vent fits against the partition plate. The bottom of the vent has multiple sealing squares in a mesh pattern.

[0007] As an improvement to the above technical solution, the vent hole has the same height at the top and bottom, and is greater than half the height of the diversion port.

[0008] As an improvement to the above technical solution, a stabilizing slot is provided on the front inner wall of the drying oven, and a stabilizing block is fixedly installed at the front end of the diversion air guide box, with the stabilizing slot and the stabilizing block slidingly engaging.

[0009] The beneficial effects of this utility model are as follows: When the non-woven fabric to be dried moves gradually from right to left inside the drying chamber, it is dried gradually from right to left by multiple air supply mechanisms. At the same time, the spacing of the air supply mechanisms can be adjusted according to the thickness of the non-woven fabric, so that the non-woven fabric is heated evenly when it is supplied with air from the top and bottom sides. This uniform heating environment will not cause the non-woven fabric to generate unidirectional shrinkage stress, thereby avoiding the non-woven fabric from wavy deformation, thus not affecting the drying quality and effect.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0013] Reference Appendix Figure 1 ,exist Figure 1 In the diagram, 'a' points to the front view and 'b' points to the right-side view. These views are only used to understand the scheme.

[0014] Please see Figure 1-6 This utility model provides a technical solution: a non-woven fabric drying mechanism, including a drying box 1, with inlets and outlets on the left and right sides of the drying box 1, and the inlet is at a high position and the outlet is at a low position. The inner wall of the rear side of the drying box 1 has multiple connecting ports 11 with the right side higher than the left side. Multiple conveying rollers 2 are rotatably arranged on the inner walls of the front and rear sides of the drying box 1 with the right side higher than the left side. The interior of the connecting port 11 is symmetrically and slidingly equipped with an air supply mechanism for adjusting the air supply distance while supplying air from both sides.

[0015] In this embodiment, when the non-woven fabric to be dried moves gradually from right to left inside the drying chamber 1, it is dried gradually from right to left by multiple air supply mechanisms. At the same time, the spacing of the air supply mechanisms can also be adjusted according to the thickness of the non-woven fabric, so that the non-woven fabric is heated evenly when it is supplied with air from the top and bottom sides. This uniform heating environment will not cause unidirectional shrinkage stress in the non-woven fabric, thereby avoiding the wavy deformation of the non-woven fabric and thus not affecting the drying quality and effect.

[0016] Specifically, the air supply mechanism includes a fixed frame plate 3, an air supply frame pipe 31, a partition plate 32, a synchronous motor 35, a bidirectional screw 36, a power clamp 37, and a drying assembly. The fixed frame plate 3 is fixedly installed on the rear side of the drying chamber 1 and located outside the connecting port 11. The air supply frame pipe 31 is fixedly installed on the inner wall of the fixed frame plate 3. The partition plate 32 is fixedly installed on the inner wall of the air supply frame pipe 31 near the front end. The front side of the partition plate 32 has symmetrically arranged diversion ports 33. The air supply frame pipe 31 is positioned on the left and right sides. Vertical slots 34 are provided on both inner walls of the partition plate 32. The synchronous motor 35 is symmetrically fixed on the top of the fixed frame plate 3. The bottom end of the synchronous motor 35 penetrates the top inner wall of the vertical slot 34. The bidirectional screw 36 is fixedly installed on the output end of the synchronous motor 35 that extends into the vertical slot 34. The power block 37 is threaded to the outside of the bidirectional screw 36. The power block 37 slides and engages with the vertical slot 34. The drying component is fixedly installed at the end of the power block 37 away from the vertical slot 34.

[0017] The drying assembly includes a diversion air guide box 4 and an air vent 41. The diversion air guide box 4 is fixedly installed at the end of the power block 37 away from the vertical slot 34. The air vent 41 is fixedly installed on the outside of the diversion air guide box 4 close to the rear end. The air vent 41 is in contact with the partition plate 32. The bottom of the air vent 41 has multiple sealing squares 42 in a mesh pattern.

[0018] In this embodiment, the air supply mechanism can dry the nonwoven fabric from both sides by adjusting the air supply distance on both sides.

[0019] Specifically, the vent 41 has the same height at the top and bottom, and is greater than half the height of the diversion port 33.

[0020] In this embodiment, the diversion air guide box 4 is adjusted up and down so that the diversion port 33 remains connected at all times.

[0021] Specifically, a stabilizing slot is provided on the front inner wall of the drying oven 1, and a stabilizing block is fixedly installed at the front end of the diversion air guide box 4. The stabilizing slot and the stabilizing block are slidably engaged.

[0022] In this embodiment, the stability of the diversion air guide box 4 is increased when it moves by sliding the stabilizing slot and the stabilizing block together.

[0023] In use, all electrical components in this device are controlled by a PLC. The rear end of each air-supplying square tube 31 is connected to a hot air pipe. Simultaneously, the synchronous motor 35 is activated according to the thickness of the non-woven fabric and the required drying efficiency. The synchronous motor 35 drives the bidirectional screw 36 to rotate. Under the constraint of the vertical slot 34, the bidirectional screw 36 drives the upper and lower power blocks 37 to adjust. The power blocks 37 on both sides adjust the distance between their corresponding diversion air guide boxes 4. When the diversion air guide box 4 moves up and down, it always maintains connection with the diversion port 33 through the air vent 41. The relative movement of the two diversion air guide boxes 4 achieves the adjustment of their relative positions. The gap between the sealing frame 42 and the non-woven fabric is such that when hot air enters the diversion air guide box 4 through the air supply frame pipe 31, it is then sprayed out through the sealing frame 42. The non-woven fabric to be dried enters the drying box 1 through the right feed port of the drying box 1 and moves to the left side by passing through the upper and lower diversion air guide boxes 4 with the cooperation of the conveying roller 2, and gradually moves downward, and then goes out through the discharge port. When the non-woven fabric passes through the diversion air guide box 4, the upper and lower diversion air guide boxes 4 spray hot air to dry it. By simultaneously supplying air to the upper and lower sides of the non-woven fabric, the non-woven fabric is heated evenly. Similarly, the working principle of the other air supply mechanisms is the same as above.

[0024] As the nonwoven fabric to be dried moves gradually from right to left inside the drying chamber 1, it is dried step by step from right to left by multiple air supply mechanisms. At the same time, the spacing of the air supply mechanisms can be adjusted according to the thickness of the nonwoven fabric, so that the nonwoven fabric is heated evenly when it is supplied with air from the top and bottom. This uniform heating environment will not cause unidirectional shrinkage stress in the nonwoven fabric, thus avoiding the nonwoven fabric from wavy deformation, and thus will not affect the drying quality and effect.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
