Description

Technical Field

[0001] This utility model belongs to the technical field of nonwoven fabric shaping devices, and in particular relates to a nonwoven fabric hot rolling shaping device. Background Technology

[0002] The nonwoven fabric hot rolling and setting device is a key piece of equipment that applies temperature and pressure to the nonwoven fabric semi-finished product through heated rollers to achieve fiber bonding, curing and morphological stability. Its core function is to use one or more pairs of metal rollers with internal hot oil or steam to perform hot pressing treatment on the carded or air-laid fiber web under set temperature, pressure and linear speed. This process allows the thermoplastic components in the fibers to melt and re-bond, thereby giving the nonwoven fabric sufficient strength, density and dimensional stability. At the same time, by changing rollers with different patterns, specific textures can be imprinted on the surface of the nonwoven fabric to meet the needs of subsequent processing or application.

This method not only has a long cooling time, but also causes uneven cooling due to factors such as ambient temperature and airflow, which in turn affects the shaping accuracy and final quality of the product, and also reduces the overall production efficiency.

Motor 313 is located on the right side of the fixed frame 312. With the processing section 3, the cooled nonwoven fabric can be automatically wound up by starting motor 313, which drives the winding roller 316 to rotate via shaft 314. When the surface of the winding roller 316 is full of nonwoven fabric and needs to be replaced, hydraulic push rod 321 can be activated. Hydraulic push rod 321 will drive the support block 322 to move downward, releasing the support limit on one end of shaft 314. Then the winding roller 316, which is fixed on shaft 314 by sliding limit and limit sleeve 315, can be removed and replaced with a new winding roller. This setting simplifies the winding roller replacement process, reduces equipment downtime, and improves overall production efficiency.

[0020] Cooling fan 218: This is a device used in the cooling process after the non-woven fabric is hot rolled and shaped. Its main function is to quickly remove the heat from the surface of the non-woven fabric through forced ventilation, thereby achieving cooling and preventing problems such as adhesion of the non-woven fabric, ensuring the smooth progress of subsequent processing. For example, the 9-26 cooling fan is one such model. It is a centrifugal fan for production lines and has the advantages of high efficiency, low noise, flat performance curve, and wide high-efficiency range.

[0021] It should be noted that the control of the liquid pump 217, cooling fan 218, motor 1 225, motor 2 313 and hydraulic push rod 321 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0022] A specific application of this embodiment is as follows: In use, the nonwoven fabric to be processed can first pass through the hot roller 311, then through the gap between the lower cooling roller box 211 and the upper cooling roller box 212, and finally one end of the nonwoven fabric is wound around the take-up roller 316. After completing the above preparations, the hot roller 311 can be started to heat-treat the nonwoven fabric. When the heat-treated nonwoven fabric needs rapid cooling, the liquid pump 217 can be started. The liquid pump 217 will draw coolant from the storage tank 216 and transport it through the connecting pipe 3 215 to the connecting pipe 1 213 and the connecting pipe 2 214. The coolant will then be diverted through these two pipes to the lower cooling roller box 211 and the upper cooling roller box 212 respectively, thus cooling the upper and lower surfaces of the nonwoven fabric passing through. Cooling is performed during the cooling process. After cooling is completed, the coolant in the lower cooling roller box 211 and the upper cooling roller box 212 will flow back to the storage tank 216 through the connecting pipe 1 213, connecting pipe 214, and connecting pipe 3 215 on the other side, realizing the recycling of coolant. While using the cooling roller boxes to cool the nonwoven fabric, the cooling fan 218 can also be started to further assist in the cooling of the nonwoven fabric. This setting can significantly improve the cooling efficiency and cooling uniformity of the nonwoven fabric, ensuring its shaping effect. If it is necessary to adjust the distance between the lower cooling roller box 211 and the upper cooling roller box 212 according to the thickness of the nonwoven fabric, the insert 233 fixed on the limiting insert plate 231 and the limiting rod 232 can be pulled out first to release the limiting rod 23. The fixing of 2 allows the limiting rod 232 to drive the rotating shaft 226 on it to rotate freely. Then, the motor 225 is started. The motor 225 will drive the two connecting rods 227 on its outer wall to rotate synchronously through the rotating shaft 226. Since the other ends of the two connecting rods 227 are hinged to the connecting rods 229 in the two U-shaped frames 228 at the top of the upper cooling roller box 212, during the rotation of the rotating shaft 226 driven by the motor 225, the upper cooling roller box 212 can move stably upward with the guidance of multiple fixing blocks 221 on it and multiple sliding rods 222 at the top of the worktable 1 through the transmission action of the connecting rods 227 and 229. This adjusts the distance between it and the lower cooling roller box 211. This device can flexibly adapt to the cooling requirements of nonwoven fabrics of different thicknesses, improving the versatility of the equipment. After cooling, the nonwoven fabric can be automatically wound up by starting motor 313, which drives the winding roller 316 through shaft 314. When the winding roller 316 is full of nonwoven fabric and needs to be replaced, hydraulic push rod 321 can be activated. Hydraulic push rod 321 will drive the support block 322 to move downward, releasing the support limit on one end of shaft 314. Then the winding roller 316, which is fixed on shaft 314 by sliding limit and limit sleeve 315, can be removed and replaced with a new winding roller. This setting simplifies the winding roller replacement process, reduces equipment downtime, and improves overall production efficiency.
