Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric hot pressing technology, specifically to a hot pressing device for all-cotton nonwoven fabric. Background Technology

[0002] The hot-pressing device for all-cotton nonwoven fabrics uses high temperature and high pressure to press the fibrous materials within the all-cotton nonwoven fabric together, forming a strong and elastic textile. This device is widely used in the nonwoven fabric manufacturing industry, especially in the production and processing of all-cotton nonwoven fabrics. However, existing hot-pressing devices for all-cotton nonwoven fabrics may experience issues such as inaccurate temperature, insufficient pressing time, and uneven hot plate surfaces, which could lead to the nonwoven fabric not sticking together after high-temperature hot-pressing during production.

[0003] A search revealed a utility model patent with publication number CN221971889U, which discloses a non-woven fabric hot pressing device. The device includes a support frame, a cylinder mounted in the middle of the top wall of the support frame, a lifting plate mounted on the output end of the cylinder, a hot pressing plate fixed to the bottom of the lifting plate, two sets of linkage rods symmetrically mounted on one side wall of the lifting plate, and two sets of linkage rods symmetrically mounted on the other side wall of the lifting plate. A rotating shaft is positioned between the linkage rods and their bottom ends. The beneficial effects are: by setting up a rotating shaft, a rubber pad, linkage rods one and two, during the downward movement of the hot pressing plate, the rotating shaft contacts the non-woven fabric beforehand. As the hot pressing plate continues to move downward, linkage rods one and two rotate. During this rotation, the rotating shaft presses the surface of the non-woven fabric, thus flattening it. Simultaneously, the rubber pad protects the surface of the non-woven fabric, effectively ensuring the hot pressing effect of the device and improving its performance.

[0004] The aforementioned patent describes how a cylinder drives a hot press plate to descend and achieve hot pressing of nonwoven fabric. However, during the hot pressing process of all-cotton nonwoven fabric, the raw materials (such as synthetic fibers) of the all-cotton nonwoven fabric undergo heating and plasticizing stages. During this stage, some chemical components in the raw materials may volatilize or decompose due to high temperatures, thereby producing harmful gases, which pose certain potential hazards to the environment and human health.

[0005] Therefore, it is necessary to invent a hot pressing device for all-cotton nonwoven fabric to solve the above problems. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-7The illustrated cotton nonwoven fabric hot pressing device includes a support plate 001. A housing 101 is fixedly connected to the upper end of the support plate 001. An inlet / outlet gate 102 is hinged to the side wall of the housing 101. Two electric slide rails 201 are fixedly connected to the upper end of the support plate 001. Electric slide rods 208 are fixedly connected to the side walls of the two electric slide rails 201. Two electric sliders 202 are slidably connected to the upper end of the electric slide rails 201. The two electric sliders 202 are internally slidably connected to the side walls of the electric slide rods 208. Multiple connecting sliders 203 are slidably connected to the upper end of the electric slide rails 201. The connecting slider 203 is internally slidably connected to the side wall of the electric slider 208. The side walls of the two electric sliders 202 are fixedly connected to the side wall of the connecting slider 203. The upper ends of the multiple connecting sliders 203 are fixedly connected to the adsorption plate 204, and the upper ends of the adsorption plate 204 are fixedly connected to the pressure plate 205. The inner wall of the housing 101 is fixedly connected to the hydraulic cylinder 301. The output end of the hydraulic cylinder 301 is fixedly connected to the hot pressure plate 302. The side wall of the hot pressure plate 302 is fixedly connected to the connecting plate 303. The lower end of the connecting plate 303 is fixedly connected to the spring rod 304. The lower end of the spring rod 304 is fixedly connected to the fixing pressure plate 305. When hot pressing is required, open the feed and discharge gate 102, place the cotton nonwoven fabric on the upper end of the pressure plate 205, close the feed and discharge gate 102, drive the electric slide rail 201, the electric slide rail 201 drives the electric slider 202 to slide laterally, the electric slider 202 slides laterally, the connecting slider 203 slides laterally, the connecting slider 203 slides laterally, the adsorption plate 204 slides laterally, the adsorption plate 204 slides laterally, the pressure plate 205 slides laterally, and thus the cotton nonwoven fabric enters the hot pressing position, the hot pressing plate 302 is opened, and it is then heated. When the heat reaches the appropriate temperature, and the pressure plate 205 reaches the hot pressing position, the hydraulic cylinder 301 is driven. The output end of the hydraulic cylinder 301 drives the hot pressing plate 302 to slide downward. The downward sliding of the hot pressing plate 302 drives the connecting plate 303 to slide downward. The downward sliding of the connecting plate 303 drives the spring rod 304 to slide downward. The downward sliding of the spring rod 304 drives the fixed pressure plate 305 to slide downward. When the fixed pressure plate 305 contacts the surface of the cotton nonwoven fabric, it presses and fixes the cotton nonwoven fabric. Then the hot pressing plate 302 continues to press down to perform hot pressing on the cotton nonwoven fabric.

[0028] A fan 401 is fixedly connected to the upper end of the support plate 001. The input end of the fan 401 passes through and is fixedly connected to the side wall of the housing 101. A purification box 403 is fixedly connected to the upper end of the support plate 001, and the output end of the fan 401 communicates with the interior of the purification box 403. When the inlet and outlet doors 102 are closed, the fan 401 is started to draw air from the interior of the housing 101. During hot pressing, harmful gases that may be generated under high temperature and high pressure are extracted and pumped into the purification box 403 for filtration and purification, reducing adverse effects on the health of operators.

[0029] The purification box 403 has multiple activated carbon purification plates 404 detachably connected inside. Activated carbon purification cotton cores 405 are detachably connected to the inner walls of the multiple activated carbon purification plates 404. When the drawn-in gas is pumped into the purification box 403, the multiple activated carbon purification plates 404 filter the gas, while the multiple activated carbon purification cotton cores 405 adsorb and purify the gas before it is discharged. This reduces the impact of potentially harmful gases generated during hot pressing on the operator's health. When it is necessary to replace the activated carbon purification cotton cores 405, simply hold the handle on the side wall of the activated carbon purification plate 404, pull out the activated carbon purification plate 404, and remove the activated carbon purification cotton cores 405 for convenient replacement.

The pressure plate 205 has multiple circular openings 206 inside, which communicate with the internal space 207. The retractable hose 402 communicates with the internal space 207. When the fan 401 is started, it simultaneously draws suction from the internal space 207, thereby making the internal space 207 a negative pressure state, thus adsorbing and fixing the cotton nonwoven fabric.

[0031] An observation glass 103 is fixedly connected to the side wall of the housing 101. After the feed and discharge doors 102 are closed, the operator can observe the transportation process of the cotton nonwoven fabric and its status during hot pressing at any time through the observation glass 103.

[0032] Multiple support columns 104 are fixedly connected to the lower end of the support plate 001. The multiple support columns 104 support the entire device and ensure the stability of the device during operation.

[0033] The working principle of this utility model is as follows: When hot pressing is required, the feed and discharge gate 102 is opened, and the cotton nonwoven fabric is placed on the upper end of the pressure plate 205. The feed and discharge gate 102 is closed, and the electric slide rail 201 is driven. The electric slide rail 201 drives the electric slider 202 to slide laterally. The lateral sliding of the electric slider 202 drives the connecting slider 203 to slide laterally. The lateral sliding of the connecting slider 203 drives the adsorption plate 204 to slide laterally. The lateral sliding of the adsorption plate 204 drives the pressure plate 205 to slide laterally, thereby bringing the cotton nonwoven fabric into the hot pressing position. The hot pressing plate 302 is opened to heat it to a suitable temperature. When the pressure plate 205 reaches the hot pressing position, the hydraulic cylinder 301 is activated. ，The output end of the hydraulic cylinder 301 drives the hot pressing plate 302 to slide downward. The downward sliding of the hot pressing plate 302 drives the connecting plate 303 to slide downward. The downward sliding of the connecting plate 303 drives the spring rod 304 to slide downward. The downward sliding of the spring rod 304 drives the fixed pressing plate 305 to slide downward. When the fixed pressing plate 305 contacts the surface of the cotton nonwoven fabric, it presses and fixes the cotton nonwoven fabric. Then the hot pressing plate 302 continues to press down to perform hot pressing on the cotton nonwoven fabric.

[0034] When the inlet and outlet gates 102 are closed, the blower 401 is started to draw air from the inside of the housing 101. During hot pressing, gases that may be harmful to the human body due to high temperature and pressure are drawn out and pumped into the purification box 403 for filtration and purification. After the drawn-out gas is pumped into the purification box 403, multiple activated carbon purification plates 404 filter the gas, and multiple activated carbon purification cotton cores 405 adsorb and purify the gas before it is discharged, reducing the impact on the operator's working environment and thus reducing the adverse effects on the operator's health. When it is necessary to replace the activated carbon purification cotton core 405, simply hold the handle on the side wall of the activated carbon purification plate 404, pull out the activated carbon purification plate 404, and take out the activated carbon purification cotton core 405 for convenient replacement.
