Description

Technical Field

[0001] This utility model relates to the field of dust-free paper technology, and more specifically, to a multi-specification wood pulp crushing device for dust-free paper production. Background Technology

[0002] Cleanroom paper, also known as dry-laid nonwoven fabric, is a type of dry-laid nonwoven fabric. Cleanroom paper has unique physical properties, including high elasticity, softness, excellent hand feel and drape, and extremely high water absorption and good water retention. It is widely used in hygiene care products, special medical products, industrial wiping products and other fields. During the production of cleanroom paper, the wood pulp needs to be crushed and processed by a crushing device.

[0003] For example, CN216800088U discloses a multi-specification wood pulp pulverizing device for cleanroom paper production. The key technical points of this device are: it includes a housing, with a feed funnel fixedly connected to the top of the housing; a first motor is bolted to one end of the housing; an installation port is opened inside the other end of the housing; the motor shaft of the first motor is fixedly connected to a drive shaft inside the housing; multiple sets of fixed cutters are regularly fixed on the inner wall of the housing; a main roller is located inside the housing; a locking block is fixedly connected to one end of the main roller; a rotating shaft is fixedly connected to the other end of the main roller; a protective cover is connected inside the installation port; a positioning post is fixedly connected to the center of the inner wall of the protective cover; a peeling groove is opened inside the surface of the main roller; and supports are fixedly installed on both sides of the main roller. The support frame is fixedly connected to a second motor, and a secondary roller is provided between the two sets of supports. Both ends of the secondary roller are fixedly connected to the motor shaft of the second motor. Multiple sets of movable cutters are regularly arranged on the surface of the secondary roller. A discharge pipe is fixedly connected to the bottom of the box, and a valve is installed on the discharge pipe. A support frame is also fixedly provided at the bottom of the box. It mainly achieves the crushing of wood pulp in the box by the combined action of fixed and movable cutters. Each set of secondary rollers is driven by an independent second motor to meet the needs of crushing wood pulp with different burst strengths, thereby improving production efficiency. This multi-specification wood pulp crushing device for dust-free paper production is simple to assemble, easy to clean and maintain, and improves the service life of the equipment. It also has good crushing effect and high applicability.

[0004] The aforementioned multi-specification wood pulp crushing device for cleanroom paper production still has certain shortcomings: since the wood pulp crushing device does not have a self-lubricating function, when the gears inside the wood pulp crushing device rust, it will affect the operation of the crushing blades, thereby reducing the working efficiency of the device. Therefore, it is necessary to provide a multi-specification wood pulp crushing device for cleanroom paper production. Utility Model Content
