Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric preparation, specifically to a nonwoven fabric hot pressing molding device. Background Technology

[0002] Nonwoven fabrics, also known as non-woven cloth or non-woven fabrics, are a type of fabric that does not require spinning or weaving processes. They are made directly from a web structure formed by the oriented or random arrangement of fibers, which is then reinforced by mechanical, thermal, or chemical methods. Unlike traditional woven or knitted fabrics, their production process is shorter and less expensive. The preparation of nonwoven fabrics requires a thermoforming device, such as the fabric thermoforming device described in Chinese Patent No. CN202123431128.8. This device includes a base frame, a conveyor belt rotatably connected to the inner side of the base frame, a forming box fixedly installed on the top of the base frame, a thermoforming mechanism fixedly installed in the center of the top of the forming box, tensioning mechanisms on both sides of the thermoforming mechanism on the top of the forming box, and guide rollers rotatably connected to both sides of the tensioning mechanism inside the forming box. It achieves good hot pressing function by bonding the hot pressing roller with the conveyor belt. At the same time, the extension spring can improve the stability and tension of hot pressing. By rotating the threaded rod, the threaded rod and the threaded groove squeeze each other, which in turn drives the tensioning roller at the bottom of the shell to move downward and press the fabric, thereby tightening the fabric and preventing wrinkles from appearing on the fabric surface, effectively improving the quality of hot pressing.

[0003] However, the above solution still has its drawbacks. The tensioning roller is moved up and down by rotating the handle to achieve the tensioning of the fabric. This operation makes it difficult to control the tension of the fabric. In addition, adjusting by rotating the handles on both sides is time-consuming and laborious. Utility Model Content

The first slider 146 is fixed on the outer wall of the top seat 142 and slides inside the forming box 130. Multiple telescopic springs 143 are provided and are fixed at equal intervals on the lower surface of the top seat 142.

[0025] Example 2: A preferred embodiment of this utility model provides a nonwoven fabric hot pressing forming device, which differs from the above embodiment only in that:

[0026] The height adjustment mechanism 170 is installed on the forming box 130 and the outer shell 181. The height adjustment mechanism 170 is used to adjust the height of the tension roller 183. The height adjustment mechanism 170 includes a lead screw 171, a guide rod 172, a connecting block 173, a motor 174, and a belt drive component 175. There are two lead screws 171 and two guide rods 172. The two lead screws 171 are rotatably mounted on the outer wall of the forming box 130.

The connecting block 173 is threaded onto the lead screw 171 and is also slidably mounted on the guide rod 172.

[0027] Example 3: A preferred embodiment of this utility model provides a nonwoven fabric hot pressing forming device, which differs from the above embodiments only in that:

[0028] The tensioning mechanism 180 is mounted on the connecting block 173. The tensioning mechanism 180 is configured to tension the nonwoven fabric. The tensioning mechanism 180 includes a housing 181, a second slider 182, and a tensioning roller 183. The housing 181 is fixed on the lower surface of the connecting block 173. The second slider 182 is fixed on the outer wall of the connecting block 173 and is slidably disposed inside the forming box 130. The tensioning roller 183 is rotatably disposed on the housing 181. The forming box 130 has a groove 190. The first slider 146 and the second slider 182 are slidably disposed on different grooves 190. The forming box 130 has a through hole 191.

[0029] Specifically, in use, the nonwoven fabric hot pressing forming device involves interlacing the fabric around the tension detection roller 150, the tension roller 183, and the hot pressing roller 145. The rotation of the hot pressing roller 145 and the conveyor belt 120 is controlled, causing the fabric to move on these components. Then, the hydraulic cylinder 141 is activated, moving the top seat 142 downwards. This allows the hot pressing roller 145 to come into contact with the conveyor belt 120, achieving a better hot pressing function. Simultaneously, the telescopic spring 143 improves the stability and tension of the hot pressing process. At the same time, the motor 174 operates, and the rotation of the motor 174's output shaft drives the lead screw 171 to rotate. The rotation of the lead screw 171 drives the belt drive component 175 to rotate, and the rotation of the belt drive component 175 drives the two lead screws 171 to rotate synchronously. The connecting block 173 moves up and down under the combined action of the lead screw 171 and the guide rod 172, thereby moving the tension roller 183 up and down. The rotation of the output shaft of the motor 174 is reversed, causing the tension roller 183 to move downward and press the fabric, thus tightening the fabric and preventing wrinkles. At the same time, the tension detection roller 150 and the tension sensor 160 can monitor the tension of the fabric in real time, making the tension of the fabric controllable. This effectively improves the hot pressing quality, resulting in higher fabric processing precision and better product quality. This nonwoven fabric hot pressing forming device uses the tension detection roller 150 and the tension sensor 160 to control the tension of the fabric. In addition, the motor 174 can realize the synchronous up and down movement of the tension roller 183, saving time and effort and providing users with a better user experience.
