Description

Technical Field

[0001] The invention relates to the technical field of sanitary napkin production, in particular to a sanitary napkin waste material recycling and pulverizing device. Background Art

[0002] Sanitary napkins are sanitary products used by women during menstruation. When producing sanitary napkins, they are usually cut into specific shapes. For example, the design of the side edges is mainly used to prevent side leakage. The scraps cut during the production of sanitary napkins form waste materials. These waste materials are mainly made of fiber materials such as cotton and non-woven fabrics or thermoplastic elastomers. These materials can be recycled and reused after proper treatment and processing. For example, through crushing, screening, drying and other steps, these scraps can be processed into raw materials suitable for granulation, and then granulated using a granulator. The granulated particles can be used to produce various fiber products, such as paper, fiberboard, etc. However, since fiber materials such as non-woven fabrics or thermoplastic elastomers in the waste have a certain degree of flexibility, the wear of the blade during recycling and crushing can easily lead to poor crushing effect of the waste, and the waste is prone to block the air pump when passing through the air pump, making the crushing efficiency of sanitary napkin waste low.

[0003] The patent document with announcement number CN213254917U discloses a sanitary napkin waste collection device for detecting waste outlets with anti-clogging of sanitary napkins, belonging to the technical field of waste collection devices, and a sanitary napkin waste collection device for detecting waste outlets with anti-clogging of sanitary napkins, comprising a base, a box body is fixedly connected to the base, a first motor is fixedly connected to the side wall of the box body, a first rotating shaft is fixedly connected to the output end of the first motor, a first gear is fixedly connected to the first rotating shaft, a second rotating shaft is rotatably connected to the inner wall of the box body, and the second rotating shaft is two symmetrically designed, and the second gear and the material-pickup wheel are fixedly connected to the two second rotating shafts. The utility model has a simple structure and is easy to operate. By setting the material-pickup wheel and the first air pump, it is ensured that the waste discharge device is not blocked and the waste discharge efficiency is improved at the same time. By setting the rotating blade, the water pump and the drying box, the recycling and reuse of the raw materials of the sanitary napkins are realized, and the practicality is greatly improved. However, the following problems still exist in the actual use of the patent:

[0004] The sanitary napkin waste collection device achieves the effect of conveying the crushed sanitary napkin waste by setting up a second air pump. However, the rotating blades are prone to wear when used for a long time, and the worn blades are prone to incomplete crushing or entanglement when crushing the flexible sanitary napkin waste. At this time, when the sanitary napkin waste is conveyed by the second air pump, it is easy to cause the air pump to be blocked, causing damage to the equipment and reducing the crushing efficiency of the sanitary napkin waste.

[0052] Working principle: Figure 1-Figure 11 As shown, when using the device, first, control the material distribution motor 505 to drive the reciprocating screw 503 to rotate, so that the reciprocating screw 503 drives the moving block 502 to slide and expand on the positioning rod 501 through the sliding block 504, so that the material distribution guide plate 506 is retracted and expanded above the recycling box 1, and then the sanitary napkin waste is put into the recycling box 1.

[0053] Secondly, the power of the crushing motor 302 on one side of the mounting frame 301 is turned on, so that the crushing motor 302 drives the crushing roller 303 to rotate. At this time, the crushing roller 303 drives the crushing blade 304 to rotate, and through the transmission of the transmission gear 317, the two groups of crushing rollers 303 rotate toward the middle at the same time to achieve the crushing of sanitary napkin waste. At the same time, the two ends of the crushing roller 303 drive the rotating shaft 306 to rotate through the transmission belt 305, and when the rotating shaft 306 drives the feeding plate 307 to rotate upward, the grinding stones 311 on both sides of the feeding plate 307 are fitted with the two sides of the cutting edge of the rotating and descending crushing blade 304, and the two sides of the crushing blade 304 push the grinding stones 311, so that the grinding stones 311 push the contraction spring 310 to contract into the contraction groove 309. At this time, under the action of the magnet 312, the iron filings generated during grinding are adsorbed.

[0054] Next, the feeding plate 307 continues to rotate after contacting the crushing blade 304. When the blowing hole 308 on one side of the feeding plate 307 is connected to the air supply port 315, the fan 316 blows air into the blowing hole 308 through the air supply pipe 314 in the middle of the rotating groove 313, so that the feeding plate 307 blows the crushed sanitary napkin waste into the storage groove 404. The blown wind is then blown out of the outside of the recovery box 1 through the exhaust net 405 and the exhaust groove 2. When the feeding plate 307 rotates to a horizontal position, the blowing hole 308 is separated from the air supply port 315, and the air supply port 315 stops supplying air to prevent the sanitary napkin waste from flying around.

[0055] Finally, when the feeding plate 307 that has finished supplying air falls on one side of the retracting scraper plate 401, the feeding plate 307 rotates and rises, pushing the retracting scraper plate 401 to drive the limiting rod 402 to retract at the recovery box 1, and causing the return spring 403 to retract, so that the retracting scraper plate 401 can scrape off the sanitary napkin waste on the feeding plate 307, and then start the process of grinding the crushing blade 304 again.
