Technical Field
[0001] The utility model relates to the technical field of luggage production, in particular to a device for preparing environmentally friendly flame-retardant composite materials for luggage. Background Art
[0002] Composite material preparation is a mixture that has played a great role in many fields and replaced many traditional materials. Composite material preparation is divided into metal-metal composite material preparation, non-metal-metal composite material preparation, and non-metal-non-metal composite material preparation according to its composition. Composite material preparation can be mainly divided into two categories: structural composite material preparation and functional composite material preparation.
[0003] Luggage, a general term for various bags used to carry items, has a history that dates back to ancient times. During the Han Dynasty, Li Mian's "Hexi Tower" recorded the phrase, "In a small space, a hundred utensils can be accommodated," which illustrates the earliest concept of luggage. Modern luggage comes in a wide variety of forms, ranging from shopping bags and handbags to suitcases. To ensure the flame retardancy of luggage, composite materials are used. During production, flame retardants are added to the base material of the luggage and mixed with the material before discharging. However, during discharging, the mixed material is easily left inside the conveying pipe, which is not tight and causes waste, and also affects subsequent discharge. Utility Model Content

[0025] See also Figure 1-5 , the utility model provides a technical solution: a device for preparing environmentally friendly flame-retardant composite materials for luggage, comprising;
[0026] A material transmission assembly is provided between the luggage raw material heating furnace 100 and the luggage base material extrusion tube 300, and the material transmission assembly includes a material conveying pipe 200, a material feeding pipe 201, a material discharging pipe 202, a connecting frame 400, and a scraper 403;
[0027] The top of the material delivery pipe 200 is fixed integrally with the material feed pipe 201, and the bottom of the material delivery pipe 200 is fixed integrally with the material discharge pipe 202. The material delivery pipe 200 is arc-shaped, and the central position of the connecting frame 400 coincides with the center of the circle of the material delivery pipe 200. Each section of the connecting frame 400 has a scraper 403, and the end of the scraper 403 is arc-shaped. The end of the scraper 403 is in contact with the inner wall of the material delivery pipe 200. When the scraper 403 scrapes the base material, it is completely in contact with the inner wall of the material delivery pipe 200, thereby preventing the base material from remaining on the inner wall of the material delivery pipe 200.
[0028] The ends of the feed pipe 201 and the discharge pipe 202 are both provided with arc-shaped sections, wherein the arc-shaped sections on the discharge pipe 202 are provided with a baffle plate 204 .
[0029] Furthermore, the feed pipe 201 is perpendicular to the discharge pipe 202 , and the bag base material extrusion pipe 300 is threadedly connected to the discharge pipe 202 .
[0030] Furthermore, there are two symmetrical blocking plates 203 on both sides of the material delivery pipeline 200, and the blocking plates 203 are fixedly connected to the material delivery pipeline 200.
[0031] Furthermore, the end of the connecting frame 400 has an integrally fixed connecting block 401, and the end of the scraper 403 has two symmetrical limit frames 404. The two sides of the connecting block 401 are fitted with the two limit frames 404, and the ends of the limit frames 404 are embedded with threaded rods 402. The two ends of the threaded rods 402 are covered with nuts for limiting and fixing. Therefore, the scraper 403 can be disassembled and maintained regularly to ensure the stable operation of the equipment.
[0032] Furthermore, the scraper 403 is made of elastic steel, and the baffle plate 204 rubs against the scraper 403, and the scraper 403 is bent during the friction, thereby preventing the scraper 403 from bringing the base material inside the conveying pipe 200 out of the conveying pipe 200. The scraper 403 has toughness, so it returns to its original state when the scraper 403 is separated from the baffle plate 204.
[0033] Furthermore, a mask 500 is provided on the outside of the feed pipe 200, which is buckled on the outside of the blocking plate 203 and fixed by screws, and a drive motor 501 is provided on one side of the mask 500, and the output end of the drive motor 501 is connected to the center position of the connecting frame 400.
[0034] Working principle: When in use, add the luggage base material and the injection molding grade halogen-free flame retardant PBT material to the interior of the luggage raw material heating furnace 100, and heat and mix the luggage base material and the injection molding grade halogen-free flame retardant PBT material through the luggage raw material heating furnace 100. Auxiliary stirring can be performed during heating to improve the mixing efficiency. The mixed flame retardant base material enters the interior of the conveying pipe 200 in liquid form through the feed pipe 201, and the driving motor 501 drives the connecting frame 400 to rotate, so that the connecting frame 400 drives multiple scrapers 403 to rotate synchronously, so that the scrapers 403 are attached to the conveying pipe. The inner wall of the channel 200 pushes the base material inside the material delivery pipe 200 downward, and the scraper 403 is completely in contact with the inner wall of the material delivery pipe 200 when scraping the base material, thereby preventing the base material from remaining on the inner wall of the material delivery pipe 200. When the scraper 403 moves to the bottom of the material delivery pipe 200, the baffle plate 204 rubs against the scraper 403, and the scraper 403 is bent during the friction, thereby preventing the scraper 403 from bringing the base material inside the material delivery pipe 200 out of the material delivery pipe 200. The scraper 403 is tough, so it returns to its original shape when the scraper 403 is separated from the baffle plate 204.
[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
