The utility model drives the first screw to rotate by the first motor, which is convenient for evenly stirring the raw materials in the stirring box, has a reasonable structural design, and improves the production quality of non-woven fabrics.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the mixing box is always in a connected state through the feed pipe, and some raw materials will fall directly from the feed pipe into the melting chamber during mixing, and these raw materials cannot be fully mixed, and some filter plates may cause filtration blockage after blocking the unmelted raw materials, resulting in some melted raw materials cannot be discharged. In view of this, we propose a high-temperature melting device for non-woven fabric manufacturing. Utility Model Content

[0006] The utility model aims to provide a high-temperature melting device for manufacturing nonwoven fabrics to solve the problems raised in the above-mentioned background technology.

[0007] In view of this, the utility model provides a high-temperature melting device for non-woven fabric manufacturing, comprising:

[0008] A heating barrel, wherein a through slot is provided on the top of the heating barrel, a stirring barrel is fixedly installed on the top of the heating barrel, the stirring barrel is connected with the through slot and the inner cavity of the heating barrel, a rotating rod is rotatably installed in the stirring barrel, and the lower end of the rotating rod passes through the through slot and extends into the heating barrel, a plurality of stirring rods of different lengths are fixedly installed on the rotating rod and located in the stirring barrel, a filter plate is fixedly installed in the heating barrel and located at the bottom end of the rotating rod, two inclined scrapers are fixedly installed on the rotating rod and located on the top of the filter plate, two baffles are slidably installed in the through slot, and the semicircular holes on the opposite sides of the two baffles are in contact with the rotating rod;

[0009] A driving assembly, the driving assembly is located in the through slot and is used to drive the two baffles to move closer to or away from each other;

[0010] The motor is fixedly installed on the top of the mixing barrel, and the output shaft of the motor passes through the top of the mixing barrel and is coaxially connected to the rotating rod. An annular groove is opened in the heating barrel, and a heating wire is fixedly installed in the annular groove.

[0011] In the present technical scheme, the staff puts the raw materials to be melted into the mixing barrel. Under the action of the two baffles, the two baffles will seal the material outlet of the mixing barrel, so that the raw materials in the mixing barrel will not fall into the heating barrel. Then, the staff starts the motor to make the output shaft of the motor drive the rotating rod to rotate. Then, the rotating rod will drive a number of stirring rods of different lengths to rotate, and the rotating rod will also drive the two inclined scrapers to rotate. When the several stirring rods rotate, the raw materials in the mixing barrel will be mixed so that the raw materials can be stirred evenly. After the raw materials are stirred evenly, the driving assembly is set to drive the two baffles to move away from each other, so that the semicircular holes on the two baffles are no longer in contact with the rotating rod, and there is a certain distance between the semicircular holes on the two baffles and the rotating rod, until the two baffles can no longer move away from each other. At this time, the inner cavity of the mixing barrel is connected to the through groove and the inner cavity of the heating barrel. Under the action of gravity, the stirred raw materials in the mixing barrel will fall into the heating barrel through the through groove;

[0012] Afterwards, the staff starts the heating wire to heat the raw materials in the heating barrel. After heating, some heated and melted raw materials will leak out from the filter plate and fall into the bottom of the inner cavity of the heating barrel and be discharged. At this time, some raw materials that have not yet melted still remain on the filter plate. At this time, the two inclined scrapers are still rotating, and the inclined scrapers will scrape up the raw materials remaining on the filter plate. In the process of scraping, the melted raw materials will leak to the bottom of the inner cavity of the heating barrel. Afterwards, the raw materials that have not yet melted fall on the filter plate again. Under the action of the continuous rotation of the two inclined scrapers, the unmelted raw materials can be prevented from clogging the filter plate, causing the melting speed to slow down.

[0013] In the above technical solution, further, the driving component includes:

[0014] A bidirectional threaded rod is rotatably mounted in the through slot, one end of the bidirectional threaded rod passes through the protrusions on the two baffles and one side of the through slot and extends to the outside, and a rocker is fixedly mounted on one end of the bidirectional threaded rod.

[0015] In this technical solution, the staff manually rotates the rocker on the bidirectional threaded rod to drive the bidirectional threaded rod to rotate. Under the action of the thread, the bidirectional threaded rod will drive the two baffles away from each other.

[0016] In the above technical solution, further, the bidirectional threaded rod is provided with two sections of threads with opposite rotation directions, and the protrusions on the two baffles are both threadedly connected to the bidirectional threaded rod.

[0017] In the technical solution, under the action of the thread, the bidirectional threaded rod can drive the two baffles to move closer to or away from each other when rotating.

[0018] In the above technical solution, further, a discharge pipe is fixedly installed at the discharge end of the heating barrel, and a valve is rotatably installed on the discharge pipe, and a feed hopper is fixedly installed on the top of the mixing barrel, and the feed hopper is connected to the inner cavity of the mixing barrel.

[0019] In this technical solution, the valve is turned and opened, and the heated and molten raw materials are discharged from the discharge pipe, ensuring that the molten raw materials can be put into the mixing barrel through the feed hopper.

[0020] In the above technical solution, further, a heat-insulating layer is fixedly installed in the heating barrel, and the heating wire is located in the heat-insulating layer.

[0021] In this technical solution, heat loss can be reduced under the action of the thermal insulation layer.

[0022] In the above technical solution, further, the output shaft of the motor is rotatably connected to the stirring barrel, and the bottom of the inner cavity of the stirring barrel and the bottom of the inner cavity of the heating barrel are both in an inverted frustum-shaped structure.

[0023] In this technical solution, it is ensured that the motor can operate normally; it is ensured that the raw materials in the inner cavity of the mixing barrel can fall into the heating barrel under the action of gravity, and the raw materials in the inner cavity of the heating barrel can be discharged from the discharge pipe under the action of gravity.

[0024] The beneficial effects of the utility model are:

[0025] The high-temperature melting equipment for manufacturing non-woven fabrics ensures that when the raw materials in the stirring barrel are stirred, the raw materials will not fall into the heating barrel, so that they can be fully mixed, and the unmelted raw materials on the filter plate can be scraped up to avoid clogging on the filter plate through the mutual cooperation between the stirring barrel, heating barrel, filter plate, inclined scraper, annular groove, insulation layer, baffle, through groove, stirring rod, rotating rod, motor and driving assembly.
