Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a hot pressing device for non-woven fabrics. Background Art

[0002] Nonwoven hot pressing is an important processing technology that transforms nonwoven fabrics into materials with a certain thickness and quality by using the pressure and temperature of a hot press. The hot pressing process can significantly enhance the strength and hardness of nonwoven fabrics, thereby increasing their service life. In the hot pressing process of nonwoven fabrics, the temperature and pressure settings of the hot press are key factors, which directly affect the quality and performance of nonwoven fabrics. In addition, the hot pressing time also needs to be precisely controlled to ensure that the nonwoven fabric is not damaged by overheating while being subjected to sufficient pressure. Nonwoven fabrics that have been hot pressed have many excellent properties, such as tensile strength, wear resistance, stability, and high temperature resistance. Therefore, the hot pressing process of nonwoven fabrics is widely used in the production of industrial products.

[0003] For example, the Chinese patent "A hot pressing device for non-woven fabrics for vehicles" with announcement number CN219260480U includes a hot pressing platform, a hot pressing box located on the surface of the hot pressing platform, a hot pressing mechanism located in the hot pressing box, the hot pressing mechanism includes a hot pressing plate, heating tubes are evenly arranged in the hot pressing plate, positioning slide rails are symmetrically formed on the inner wall of the hot pressing box, both ends of the hot pressing plate are slidably connected to the positioning slide rails through sliders, the conveying mechanism is distributed on both sides of the hot pressing box, and the hot pressing mechanism also includes a cylinder, which is located in the hot pressing plate. At the top of the press box, the output end of the cylinder is connected to a hot pressing plate, and a support plate matched with the hot pressing plate is arranged on the hot pressing platform. The conveying mechanism includes a feed roller group and a winding roller arranged along the conveying direction of the non-woven fabric, and the feed roller group includes a heat-conducting roller No. 1, a heat-conducting roller No. 2, a heat-conducting roller No. 3, and a heat-conducting roller No. 4 arranged in sequence, and heating wires are provided in the feed roller group. The heat-conducting roller No. 1, the heat-conducting roller No. 2, the heat-conducting roller No. 3, and the heat-conducting roller No. 4 are distributed in an inverted U shape, and the running trajectory of the non-woven fabric passing through the feed roller group is U-shaped.

[0004] Although the above-mentioned prior art can realize hot pressing of non-woven fabrics, in actual use, on the one hand, the position of the non-woven fabric is easy to shift during the conveying process. When the non-woven fabric is hot pressed, the winding roller will roll the non-woven fabric on its surface, causing the non-woven fabric that has not been hot pressed to shift on the hot pressing table, thereby reducing the hot pressing quality of the non-woven fabric. On the other hand, the non-woven fabric is easy to wrinkle during the hot pressing process, and the wrinkles generated during the rolling process of the non-woven fabric are difficult to handle, resulting in the wrinkled non-woven fabric being directly rolled up on the winding roller, thereby affecting the overall quality of the non-woven fabric. Therefore, it does not meet the existing needs. In this regard, we propose a hot pressing device for non-woven fabrics. Utility Model Content

[0005] The utility model aims to provide a heat pressing device for nonwoven fabrics, so as to solve the problems in the above background technology that the nonwoven fabrics are easily shifted during the conveying process and wrinkles are easily generated during the heat pressing process.

The first hydraulic telescopic devices are equidistantly distributed, and the telescopic ends of the first hydraulic telescopic devices extend to the bottom of the cross plate of the first mounting frame, and a hot pressing plate is fixedly provided at the lower end of the telescopic end of the first hydraulic telescopic device located below the cross plate of the first mounting frame.

[0012] Preferably, a heating platform is fixedly provided on the upper end of the workbench below the hot pressing plate, and the heating platform corresponds to the position of the hot pressing plate.

[0013] Preferably, heating wires are provided inside the hot pressing plate and the heating platform, and the heating wires are bent in an S-shape.

[0014] Preferably, a third mounting frame is fixedly provided at the upper end of the workbench located on the outer side of the limit block on the other side, a winding drum is provided inside the third mounting frame, and the winding drum is rotatably connected to the third mounting frame, a motor is fixedly provided at the rear end outside the third mounting frame, and the output shaft of the motor extends to the interior of the third mounting frame and is fixedly connected to the winding drum.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can limit the non-woven fabric during transportation through the limit block and the third hydraulic telescopic device. Before the non-woven fabric is hot-pressed, one end of the non-woven fabric passes through the limit blocks and the limit rollers on both sides and is fixed on the winding roller. The third hydraulic telescopic device is turned on to make the telescopic end of the third hydraulic telescopic device drive the moving rod to move inside the slide groove. At this time, the limit block also moves with the moving rod until the limit block positions the front and rear ends of the non-woven fabric in the grooves of the limit block. At this time, the non-woven fabric is hot-pressed to avoid the non-woven fabric from being offset during hot pressing, thereby improving the hot pressing quality of the non-woven fabric.

[0017] 2. The utility model can flatten the non-woven fabric through the second hydraulic telescopic device and the limiting roller. Before the non-woven fabric is hot-pressed, one end of the non-woven fabric passes through the limiting rollers on both sides and is fixed on the winding roller. At this time, the second hydraulic telescopic device is turned on to make the telescopic end of the second hydraulic telescopic device drive the first mounting ear plate to move downward. At this time, the limiting roller on the first mounting ear plate also moves downward with the first mounting ear plate until the limiting roller contacts and squeezes the upper end of the non-woven fabric and the lower end of the non-woven fabric contacts the fixed roller. At this time, the non-woven fabric is hot-pressed and wound up, which can avoid wrinkles on the non-woven fabric during hot pressing and winding, thereby improving the quality of the non-woven fabric product.

[0018] 3. The utility model can heat the non-woven fabric evenly for hot pressing through the first hydraulic telescopic device and the heating wire. When the hot pressing operation is performed, after the non-woven fabric is moved to a suitable position, the heating wire is energized. When the current passes through the heating wire, the current acts on the resistance inside the heating wire, thereby causing the heating wire to heat up. Then the first hydraulic telescopic device is turned on, so that the telescopic end of the first hydraulic telescopic device drives the hot pressing plate to move downward until the hot pressing plate is moved to contact and squeeze the non-woven fabric, thereby avoiding the situation where the non-woven fabric has inconsistent colors and patterns due to uneven heating, thereby further improving the hot pressing quality of the non-woven fabric.
