Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, and more particularly to a protective feeding mechanism for a carding machine used in non-woven fabric production. Background Art

[0002] Non-woven fabric is a fiber mesh structure textile made from fibers as raw materials, formed into a fiber web (layer) and processed by chemical or physical methods. The processing of non-woven fabric requires steps such as opening and blending cotton, carding, web laying, needle punching combination, hot rolling and setting, and winding. After being mixed in a vibrating cotton box, it needs to enter a carding machine for fiber carding operation.

[0003] In the existing carding machine, raw materials are conveyed into a feeding box through a conveyor belt. The height between the pressure roller and the feeding roller in the feeding box is fixed and cannot be adjusted according to actual needs. During the feeding process, material accumulation is likely to occur, resulting in jamming of the feeding roller and affecting the normal feeding of the carding machine. When the feeding machine jams, it usually needs to be dredged and adjusted manually. Moreover, the feeding port of the existing feeding box is exposed. When the staff is dredging, the rotating feeding roller and pressure roller are likely to squeeze the staff's hands, posing a great safety hazard. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a protective feeding mechanism for a carding machine used in non-woven fabric production, which can adjust the height of the pressure roller according to the thickness of the feeding raw material, and at the same time provide protection during the feeding process to reduce the safety hazard during the feeding process.

At the front end of the frame, a conveyor belt for conveying materials is inclined downward. Behind the conveyor belt, a feeding roller is provided. Above the feeding roller, a pressure roller is provided through a pressure roller mounting block, and the pressure roller is arranged on the pressure roller mounting block through a bearing. The pressure roller mounting block is arranged on the frame through two support rods, and an adjusting mechanism for adjusting the height of the pressure roller mounting block is arranged on the support rods. Inside the frame, a motor for driving the conveyor belt to convey materials forward is provided, and the motor drives the feeding roller and the pressure roller to act through a transmission mechanism. On both sides of the conveyor belt, baffle plates for preventing materials from falling are provided, and on the baffle plates, cover plates for enclosing and protecting the conveyor belt, the feeding roller and the pressure roller are provided.

[0007] Further optimizing the technical solution, the adjusting mechanism includes a cross bar arranged on the two support rods. The pressure roller mounting block is arranged at the bottom of the cross bar through a compression spring, and a bolt for adjusting the height of the cross bar is arranged between the cross bar and the support rod.

[0008] Further optimize the technical solution. The transmission mechanism includes a conveyor gear arranged on the motor. A first pressure roller gear for connecting the pressure roller is arranged on the pressure roller mounting block on the same side as the conveyor gear. A chain is arranged between the conveyor gear and the first pressure roller gear. A second pressure roller gear is arranged on the pressure roller mounting block at the other end of the pressure roller. A third pressure roller gear meshing with the second pressure roller gear is arranged on the pressure roller mounting block through a gear plate. The third pressure roller gear is provided with a feeding gear connected to the feeding roller through a chain.

[0009] Further optimize the technical solution. A material guiding plate for guiding the material is arranged between the conveyor belt and the feeding roller.
