Description

Technical Field

[0001] This utility model relates to the field of dust-free paper processing technology, specifically to a raw material crushing device for dust-free paper processing. Background Technology

[0002] Cleanroom paper, also known as dry-laid nonwoven fabric, is a type of dry-laid nonwoven fabric made from wood pulp fibers using air-laid technology. It possesses high elasticity, softness, and strong water absorption, and is widely used in hygiene care and industrial wiping applications. The main raw material for cleanroom paper is wood pulp fiber, and production utilizes air-laid technology, reinforced by chemical or thermal bonding. Chemically bonded products are often used in industrial wipes and feminine hygiene products, while thermally bonded products offer better moisture absorption and are commonly used in highly absorbent hygiene products. Cleanroom paper uses 100% wood pulp fiber as raw material, which needs to be broken down into single fibers by crushing equipment to meet the requirements of the air-laid process. To improve the processing efficiency of cleanroom paper, a raw material crushing device is required; however, existing raw material crushing devices still have the following shortcomings: When existing raw material crushing equipment is in use, dust tends to escape at the feed inlet during the crushing process, which can affect the processing environment of the production workshop and the physical and mental health of the workers. At the same time, existing raw material crushing equipment only has a relatively simple dust treatment structure, which makes it difficult to effectively purify the dust, resulting in reduced practicality and efficiency of the raw material crushing equipment.

Detailed Implementation

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] like Figure 1 , Figure 2 and Figure 3As shown, a raw material crushing device for dust-free paper processing includes a workbench 1 and a dustproof component 4. A processing box 2 is installed on the upper right side of the workbench 1, and a feeding hopper 3 is provided on the upper end of the processing box 2. The dustproof component 4 is provided on the upper end of the feeding hopper 3. The dustproof component 4 includes a water storage tank 401, a water pump 402, a water delivery pipe 403, a filter element 404, a water collection frame 405, an atomizing nozzle 406, a blower 407, a filter cartridge 408, an internal threaded groove 409, an external threaded mounting part 410, an air guide pipe 411, a connecting groove 412, and a rubber sealing ring 413. The water pump 402 is installed on the upper end of the water storage tank 401, and the water pump 402 is externally connected to the water delivery pipe 403. The filter element 404 is provided in the middle of the water delivery pipe 403. A water collection frame 405 is installed at the front end of the workbench 1. An atomizing nozzle 406 is installed on the upper inner side of the water collection frame 405. An exhaust fan 407 is installed behind the workbench 1, and a filter cartridge 408 is connected to the upper end of the exhaust fan 407. The filter cartridge 408 has internal threaded grooves 409 at both ends, and an external threaded mounting part 410 is connected inside the internal threaded groove 409. An air guide pipe 411 is installed outside the external threaded mounting part 410. The filter cartridge 408 has mating grooves 412 at both ends, and a rubber sealing ring 413 is connected inside the mating groove 412. The atomizing nozzle 406 is perpendicular to the water collection frame 405 and is fixedly connected to the water collection frame 405 by bolts. The internal dimensions of the internal threaded groove 409 and the external threaded mounting part 410 are the same. The external dimensions of the filter cylinder 408 are compatible, and the external threaded mounting part 410 is rotatably connected to the filter cylinder 408 through the internal threaded groove 409. The internal dimensions of the mating groove 412 are compatible with the external dimensions of the rubber sealing ring 413, and the rubber sealing ring 413 is connected to the filter cylinder 408 through the mating groove 412. There are two rubber sealing rings 413, which are symmetrically arranged at both ends of the filter cylinder 408 around the central axis of the side of the filter cylinder 408. The water pump 402 is fixedly installed on the upper end of the water storage tank 401 by fastening bolts. The water pump 402 is used to transport the clean water inside the water storage tank 401 into the water collection frame 405 through the water supply pipe 403. At the same time, it works with the filter element 404 to filter the impurities that may be contained in the water. This design allows clean water to enter the water collection frame 405 and then be sprayed directly through the atomizing nozzle 406, preventing the atomizing nozzle 406 from becoming clogged with scale after long-term use. Spraying an appropriate amount of water causes dust particles to combine with the water and settle. Meanwhile, the exhaust fan 407 located behind the workbench 1 provides suction to the air duct 411. The internal dimensions of the internally threaded grooves 409 at both ends of the filter cylinder 408 are matched with the internal dimensions of the externally threaded mounting parts 410 added to the outside of the air duct 411. Thus, the air duct 411 is rotatably mounted on both ends of the filter cylinder 408 through the internally threaded grooves 409 and the externally threaded mounting parts 410. Furthermore, the internal dimensions of the mating grooves 412 at both ends of the filter cylinder 408 are matched with the external dimensions of the rubber sealing rings 413.The rubber sealing ring 413 increases the sealing performance of the air guide pipe 411 and the filter cylinder 408 after installation, preventing dust from escaping from the connection point. This allows the air guide pipe 411 to transport dust from the feed hopper 3 to the filter cylinder 408, where the filter cylinder 408 filters the dust, controlling dust diffusion at the source and improving the safety of the raw material crushing device during operation.

[0018] like Figure 1 and Figure 4 As shown, the processing box 2 is equipped with a crushing assembly 5, which includes a drive motor 501, a drive gear 502, a first crushing roller 503, a driven gear 504, and a second crushing roller 505. The drive motor 501 is connected to the drive gear 502 at its front end, and the drive gear 502 is connected to the first crushing roller 503 at its front end. The driven gear 504 meshes with the drive gear 502 externally, and the second crushing roller 505 is connected to the front end of the driven gear 504. The drive gear 502 and the driven gear 504 mesh, and the driven gear 504 is rotatably connected to the processing box 2 through the drive gear 502. The outer sides of the first crushing roller 503 and the second crushing roller 505 are horizontally distributed, and the outer surface of the first crushing roller 503 is parallel to the outer surface of the second crushing roller 505. The outer surface of the 505 is tightly fitted, and the drive motor 501 is fixedly installed on the upper left side of the workbench 1 by fastening bolts. The output shaft of the drive motor 501 is connected to the drive gear 502 through a coupling. When the drive motor 501 operates, it drives the drive gear 502 to rotate, so that the first crushing roller 503 connected to the front end of the drive gear 502 rotates inside the processing box 2. At the same time, the drive gear 502 meshes with the driven gear 504, so that the rotation of the drive gear 502 drives the driven gear 504 to rotate, and drives the second crushing roller 505 connected to the front end of the driven gear 504 to rotate as well. The first crushing roller 503 and the second crushing roller 505 are used to crush the raw materials for dust-free paper processing, thereby improving the overall practicality and efficiency of the raw material crushing device.

[0019] In summary, the raw material crushing device for cleanroom paper processing, during use, firstly, fixes the processing box 2 to the upper right side of the workbench 1 with fastening bolts, and then fixes the feed hopper 3 to the upper end of the processing box 2 with fastening bolts. The drive motor 501 drives the drive gear 502 to rotate, causing the first crushing roller 503 connected to the front end of the drive gear 502 to rotate inside the processing box 2. Simultaneously, the driven gear 504 meshes with the drive gear 502 externally, causing the drive gear 502 to rotate, which in turn drives the driven gear 504 to rotate, and consequently, the second crushing roller 505 connected to the front end of the driven gear 504 to rotate. The first crushing roller 503 and the second crushing roller 505 are used to crush the cleanroom paper processing raw materials. Next, the water pump 402 pumps clean water from the water tank 401 into the water collection frame 405 through the water pipe 403, while simultaneously filtering... Component 404 filters impurities that may be present in the water, allowing clean water to be sprayed directly out through the atomizing nozzle 406 after entering the water collection frame 405. This prevents the atomizing nozzle 406 from being clogged by scale after long-term use. By spraying an appropriate amount of water, dust particles combine with the water and settle. The operation of the exhaust fan 407 located behind the workbench 1 provides a certain suction force to the air guide pipe 411. The air guide pipe 411 is rotated and installed on both ends of the filter cylinder 408 through the internal thread groove 409 and the external thread mounting part 410. The rubber sealing ring 413 increases the sealing performance after the air guide pipe 411 and the filter cylinder 408 are connected, preventing dust from escaping from the connection. The air guide pipe 411 transports the dust inside the feed hopper 3 to the inside of the filter cylinder 408, where the filter cylinder 408 filters the dust, controlling dust diffusion at the source and improving the safety of the raw material crushing device during use.
