DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1 - Figure 4 The utility model provides a technical solution: a hot pressing mill for preparing high-elastic polypropylene non-woven fabrics, comprising a mill body 100, a hot rolling roller 101 is arranged inside the mill body 100, and a protective cooling mechanism 200 located in front of the hot rolling roller 101 is arranged on the front surface of the mill body 100. The protective cooling mechanism 200 can be used to protect the outer side of the hot rolling roller 101 to avoid accidental injury caused by touching during the hot rolling of the non-woven fabric, thereby increasing the safety and stability of the hot rolling of the non-woven fabric. At the same time, the hot-rolled non-woven fabric can be quickly cooled at any time to facilitate the forming and rolling of the non-woven fabric. The protective cooling mechanism 200 includes a rotating cooling mechanism 200 mounted on the mill body 101. 0 The protective shell 201 on the front surface is hollowed out for ventilation. A plurality of horizontal tubes 202 are horizontally arranged inside the protective shell 201. Each horizontal tube 202 is located outside each hot rolling roller 101. An air pump 204 is arranged on the top of the protective shell 201. A filter is arranged at the air inlet of the air pump 204. An insulation box 203 is arranged between the air pump 204 and the protective shell 201 to facilitate refrigeration of a cooling component 207 inside the insulation box 203. A cooling component 207 is arranged inside the insulation box 203. The cooling component 207 includes a corrugated cooling plate 2071. The corrugated cooling plate 2071 can increase the contact area with the gas.

[0023] In this embodiment, preferably, the cooling component 207 also includes a support column 2072 rotatably installed between the middle of the corrugated cooling plate 2071 and the inner wall of the insulation box 203, which supports the corrugated cooling plate 2071 and facilitates the corrugated cooling plate 2071 to swing around the support column 2072. The upper and lower surfaces of the outer ends of the two corrugated cooling plates 2071 are provided with fixed columns 2073, and a rotating connecting plate 2074 is rotatably provided on the two opposite fixed columns 2073. The rotating connecting plate 2074 can facilitate the synchronous swinging of the two corrugated cooling plates 2071.

[0024] In this embodiment, preferably, connecting pipes 205 are provided between the plurality of transverse tubes 202 , and a plurality of cooling nozzles 206 are provided on the front surface of the transverse tube 202 along the length direction thereof, and the spraying range of the cooling nozzles 206 completely covers the hot rolling roller 101 .

[0025] In this embodiment, preferably, the upper end of the connecting pipe 205 is connected to the bottom of the insulation box 203 to facilitate the cooled gas to be sent into the multiple horizontal pipes 202, and the exhaust port of the air pump 204 is connected to the side of the insulation box 203, so that the gas sucked from the outside can be sent into the insulation box 203.

[0026] In this embodiment, preferably, a cleaning component 300 is provided inside the protective shell 201, and the cleaning component 300 is tilted and located on the outside of the hot rolling roller 101. Before the hot rolling of the hot rolling roller 101, the surface of the hot rolling roller 101 can be frictionally cleaned to avoid particle impurities adhering to the surface. The cleaning component 300 includes an inner rod 301 located on the outside of the hot rolling roller 101, and a cleaning sleeve 302 is sleeved on the inner rod 301. The cleaning sleeve 302 can be a cotton sleeve. A telescopic cylinder 304 is tiltedly provided on the inner wall of the protective shell 201. The telescopic cylinder 304 can drive the cleaning sleeve 302 to move closer to the hot rolling roller 101 by telescoping. The upper end of the telescopic cylinder 304 is connected to the outer end of the inner rod 301, and a stable seat 303 is provided on the inner wall of the protective shell 201 to support the telescopic cylinder 304, so as to increase the working stability of the telescopic cylinder 304.

[0027] In this embodiment, preferably, one end of the protective shell 201 is hinged to the rolling mill body 100 , and a buckle is provided between the other end of the protective shell 201 and the rolling mill body 100 to facilitate the protective shell 201 to rotate open or close to protect the hot rolling roller 101 .

[0028] In summary, before the hot rolling roller 101 hot-rolls the non-woven fabric, the protective shell 201 is rotated and stuck on the surface of the rolling mill body 100, and is located on the outside of the hot rolling roller 101. The telescopic cylinder 304 works, and the internal piston rod extends to drive the cleaning sleeve 302 to move obliquely, so that the cleaning sleeve 302 is close to the hot rolling roller 101 and contacts it. As the hot rolling roller 101 rotates, its surface rubs against the cleaning sleeve 302 to clean up the particle impurities attached to the surface of the hot rolling roller 101. The telescopic cylinder 304 works again, and the internal piston rod retracts to drive the cleaning sleeve 302 away from the hot rolling roller 101, which does not affect the hot rolling processing of the non-woven fabric. When the non-woven fabric hot-rolled by the roller 101 needs to be cooled, the air pump 204 works to suck air into the insulation box 203, and the gas impacts the corrugated refrigeration plate 2071, which cools the gas. At the same time, the corrugated refrigeration plate 2071 swings slightly due to the gas, stirring the surrounding airflow to facilitate the air to fully contact the corrugated refrigeration plate 2071. The cooled gas enters the connecting pipe 205, and is then sent into the multiple horizontal pipes 202, and then sprayed out through the cooling nozzle 206 to act on the hot roller 101 and the surface of the non-woven fabric, so as to quickly cool the non-woven fabric and improve the molding quality of the non-woven fabric.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
