It can be used to make various high-end soft bulletproof vests, bulletproof and impact-resistant helmets, bulletproof shields, public safety equipment, transportation safety packaging, protective devices for vehicles, ships, and aircraft, explosion-proof devices, military armor, etc.

[0003] In the production process of the aramid non-woven fabric production line in the prior art, the aramid non-woven fabric is usually coated with glue first, then laminated and then heated and dried. This production method not only makes the production efficiency of the aramid non-woven fabric slow, but also causes a large amount of glue to adhere to the laminating device during lamination, which needs to be cleaned, affecting the production efficiency of the aramid non-woven fabric production line. Therefore, it is necessary to propose an efficient aramid non-woven fabric continuous production line to solve the above-mentioned problems. Utility Model Content

[0004] In view of the problems in the related technology, the utility model proposes an efficient continuous production line of aramid non-woven fabric to overcome the above technical problems existing in the existing related technology.

[0005] To this end, the specific technical solutions adopted by the utility model are as follows:

[0006] A high-efficiency aramid non-weft cloth continuous production line comprises a creel, a wire separation frame is fixedly installed on one side of the creel, a supporting frame is fixedly installed on one side of the wire separation frame, a tensioner is fixedly installed on one end of the upper surface of the supporting frame, a wire laying device is rotatably installed on one side of the tensioner, a guide roller one is rotatably installed on one side of the wire laying device, a glue coating roller is rotatably installed on one side of the guide roller one, a glue dipping box is fixedly installed below the glue coating roller, a guide roller two is rotatably installed on one side of the glue dipping box, a film placing frame is fixedly installed on the surface of one side of the supporting frame, film placing rollers are rotatably installed on both ends of the film placing frame, a film laying guide roller is rotatably installed on one side of the film placing roller, a heating compound device is arranged below the film laying guide roller, an air supply pipe is fixedly installed inside the supporting frame, an air outlet pipe is fixedly installed on the surface of the air supply pipe, one end of the air supply pipe is fixedly connected to an air inlet pipe, and a blower is fixedly connected to the air inlet pipe.

[0007] Furthermore, in order to collect the aramid non-woven fabric after production and forming, a cooling roller is rotatably installed on one side of the heating and compounding device, a winding roller is rotatably installed on the end of the supporting frame, a driven wheel is fixedly installed on one end of the winding roller, a transmission belt is slidably installed on the driven wheel, a transmission motor is fixedly installed on the bottom of the supporting frame, a driving wheel is fixedly installed on the transmission shaft of the transmission motor, the driven wheel is rotatably connected to the driving wheel through the transmission belt on the surface, the driving wheel is driven to rotate by the transmission motor, and the driving wheel drives the driven wheel and the winding roller to rotate through the transmission belt to collect the composite cooled aramid non-woven fabric.

[0008] Furthermore, in order to achieve simultaneous drying and compounding of aramid fiber and PE film, the heating compounding device is composed of a plurality of electric heating rollers arranged up and down. The aramid fiber and PE film to be compounded are placed in the arrangement gap of the electric heating rollers, so that the electric heating rollers squeeze them and generate heat themselves at the same time, so that the glue during compounding is gradually dried.

[0009] Furthermore, in order to achieve drying and cooling of the aramid non-woven fabric, the air outlet pipe is fixedly installed under the heating and compounding device and the cooling roller respectively. The wind blown out by the air outlet pipe dries the aramid non-woven fabric during heating and compounding.

[0010] Furthermore, in order to provide raw materials for the production of aramid non-woven fabric, aramid fibers are wound and installed on one side surface of the creel.

[0011] Furthermore, in order to realize the compounding of the aramid fiber after the glue coating, the surfaces of the film-releasing rollers at both ends of the film-releasing frame are wound with PE films, and the PE films are covered on the surfaces of the aramid fiber after the glue coating to perform extrusion compounding.

[0012] Furthermore, in order to guide the PE film at the upper and lower ends of the film rack, a film laying groove is opened on the surface of the supporting frame, a conveying rod is fixedly installed in the film laying groove, and film laying guide rollers are rotatably installed at both ends of the conveying rod. The PE film is guided by the rotatably installed film laying guide rollers.

[0013] The beneficial effects of the utility model are:

[0014] 1. PE film is laid on both the upper and lower surfaces of the aramid fiber after glue coating through the film placing rollers installed at the upper and lower ends of the film placing frame, and the glue on the surface of the aramid fiber is laminated and covered to prevent the glue from adhering to the surface of the heating compounding device when the heating compounding device squeezes and compounds the aramid fiber.

[0015] 2. When the aramid fiber and PE film are extruded and compounded by the heating compounding device, they are heated at the same time, and then blown and dried through the air outlet pipe below during compounding, so that the extrusion compounding and drying of the aramid non-woven fabric can be carried out simultaneously, which greatly improves the production efficiency of the aramid non-woven fabric production line.
