Description

Technical Field

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

[0002] Drying equipment for nonwoven fabric processing is one of the key pieces of equipment in the nonwoven fabric production process. It is mainly used to dry damp nonwoven fabric to the required degree of dryness, ensuring the quality of the nonwoven fabric and the smooth progress of subsequent processing. The humidity control of nonwoven fabric has a significant impact on its physical properties, hand feel, color, thickness, and other characteristics; therefore, the drying equipment plays a vital role in the entire production process.

[0003] CN212390796U discloses a drying device for nonwoven fabric processing, including a main body of the drying device with a conveyor belt in the middle. This drying device for nonwoven fabric processing is equipped with a limiting auxiliary mechanism and a drying auxiliary mechanism. It can be installed using a mounting plate, and the length of the telescopic shaft can be adjusted. This allows the guide wheel at the lower end of the crossbeam to better maintain the distance between itself and the product, effectively preventing the product from detaching from the conveyor belt without affecting product transport. Especially during blower drying, this results in higher overall operating efficiency. Furthermore, by adjusting the air guide plate to a suitable angle, the airflow blowing down from above can be guided to the air inlets on both sides, then transported through the air duct to the bottom of the product, and finally blown onto the reverse side of the nonwoven fabric through the downdraft, leading to better application prospects.

[0004] In the above technical solution, a conveyor belt is used to transport the non-woven fabric, and a blower is used to dry the wet non-woven fabric. However, the non-woven fabric may contain a lot of water before drying. Relying on a single blower to dry the continuously transported non-woven fabric is difficult to completely dry it, resulting in the non-woven fabric still being wet after being rolled up.

The inner wall of the sliding groove 77 is slidably connected to a limiting block 79, and the side of the limiting block 79 away from the sliding groove 77 is fixedly connected to the outer wall of the outer frame 75.

[0026] The nonwoven fabric can be squeezed by the extrusion roller 76, which works in conjunction with the guide roller 5 to squeeze out the water contained inside the nonwoven fabric, making it easier to dry.

[0027] Among them, a spring 78 is fixedly connected to the bottom of the inner side of the slide 77, and the end of the spring 78 away from the inner wall of the slide 77 is fixedly connected to the bottom of the limiting block 79. A water collecting hopper 710 is fixedly connected to the bottom of the inner side of the drying box 1, and a storage box 711 is fixedly connected to the bottom of the water collecting hopper 710.

[0028] The height of the outer frame 75 can be adjusted by the spring 78, which in turn adjusts the height of the extrusion roller 76, allowing the device to adapt to nonwoven fabrics of different thicknesses.

[0029] The outer wall of the drying box 1 is provided with a winding mechanism 4, and the outer wall of the drying box 1 is fixedly connected with a first fixing block 41 and a second fixing block 46.

[0035] This utility model provides a drying device for non-woven fabric processing, the specific working principle of which is as follows:

[0036] In use, the nonwoven fabric to be dried is introduced into the drying chamber 1, and the hot air blower 3 is turned on. The nonwoven fabric passes between the extrusion roller 76 and the guide roller 5. The extrusion roller 76 is squeezed by the nonwoven fabric, which drives the outer frame 75 to move downward. The outer frame 75 drives the limiting block 79 to move on the inner wall of the slide groove 77, squeezing the spring 78. The spring 78, under compression, applies a reverse supporting force to the limiting block 79 based on its own elasticity. The limiting block 79 drives the extrusion roller 76 to squeeze the nonwoven fabric, squeezing out the water contained inside the nonwoven fabric. The water enters the storage box 711 through the water collection hopper 710. The hot air blower 3 dries the nonwoven fabric through the air outlet duct 6. The guide plate 72 set on the inner wall of the air outlet duct 6 guides some of the hot air. The air enters the interior of the connecting pipe 73 through the air outlet 71, and is then conveyed upward by the air guide 74 to dry the lower surface of the non-woven fabric. This allows the device to dry the non-woven fabric comprehensively, improving the drying effect. The motor 42 is turned on, which drives the connecting bearing 43 to rotate. The rotation of the connecting bearing 43 drives the winding roller 45 to rotate, and the winding roller 45 rotates to wind up the dried non-woven fabric. After winding, the limiting plate 49 is rotated, which causes the torsion spring rod 48 to deform. The limiting plate 49 disengages from the limiting of the mounting block 47, moves the mounting block 47, and disengages from the interior of the second fixing block 46. This also causes the winding roller 45 to disengage from the interior of the connecting bearing 43, making it easier for workers to unload the non-woven fabric.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
