Description

Technical Field

[0001] The utility model belongs to the field of non-woven fabric processing equipment and relates to a non-woven fabric pre-pressing mechanism. Background Art

[0002] Non-woven fabrics are made of directional or random fibers. Since non-woven fabrics have no warp or weft, they are very convenient to cut and sew, and they are light and easy to shape, so they are very popular among handicraft enthusiasts. An existing pre-pressing device for non-woven fabric processing is usually provided with a bottom plate, on which a main pressing roller and a slave pressing roller are provided, and the non-woven fabric passes between the main pressing roller and the slave pressing roller, and the non-woven fabric is pre-pressed by the pressure between the main pressing roller and the slave pressing roller.

[0003] The patent document with publication number CN219045014U discloses a pre-pressing device for the production and processing of needle-punched non-woven fabrics, comprising two support plates, two rotating shafts rotatably installed between the two support plates, rotating rollers are fixedly sleeved on the outer sides of the two rotating shafts, and the two rotating rollers are transmission-connected to the same conveyor belt, and the beating plate is driven by the collision between the striking rod and the U-shaped plate to achieve repeated intermittent beating of the non-woven fabric, thereby achieving the effect of flattening and pre-pressing the non-woven fabric, and can also beat away the floating dust on the surface of the non-woven fabric.

[0004] However, the above-mentioned prior art still has the following deficiencies: when the above-mentioned prior art performs pre-pressing treatment on the non-woven fabric, impurities such as hair fragments and dust will gradually adhere to the surface of the rotating roller. Since the cleanliness of the surface of the rotating roller will affect the pre-pressing quality of the non-woven fabric, it is necessary to clean the impurities on the surface of the rotating roller. However, the above-mentioned prior art does not have a cleaning mechanism for timely cleaning the debris on the surface of the pressing roller. After using it for a period of time, the equipment needs to be stopped and manually cleaned, which is inconvenient to clean and greatly reduces the processing efficiency. Utility Model Content

[0005] The utility model aims to solve the technical problem mentioned in the background art that the prior art needs to stop the machine to manually clean the rotating roller, which greatly reduces the processing efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A non-woven fabric pre-pressing mechanism comprises a dustproof box, in which two pressure rollers symmetrically arranged up and down are rotatably connected, and the dustproof box has feeding ports at both front and rear ends, and two partitions symmetrically arranged up and down are fixed to the inner wall of the dustproof box, and the two partitions are located between the two pressure rollers, and the two partitions are respectively provided with through holes for the two pressure rollers to partially pass through, a scraper is fixed to one side of the partition, and one end of the scraper is against the outer wall of the pressure roller, and two cleaning components symmetrically arranged and respectively located on one side of the two partitions are provided in the dustproof box, and a cleaning brush is slidably provided on the cleaning component, and one end of the cleaning brush is against the outer wall of the scraper, and two dust suction components symmetrically arranged and respectively located on one side of the two partitions for absorbing debris in the dustproof box are fixed to the inner wall of the dustproof box, and the feeding port is located between the two partitions.

[0008] Working principle:

[0009] The non-woven fabric passes through the feed port and between the two pressure rollers. The two pressure rollers rotate to pre-press the non-woven fabric. While the two pressure rollers are rotating, the outer walls of the pressure rollers and one end of the scraper are in contact with each other. The scraper scrapes off the dust and lint adhered to the outer walls of the pressure rollers. The dust and lint scraped and accumulated on the scraper are cleaned by a cleaning brush to clean the scraper surface, thereby avoiding the problem of excessive accumulation of dust and lint on the scraper surface due to long-term cleaning, which makes it inconvenient to clean the pressure roller surface later. The dust and lint scraped off by the scraper and the dust and lint brushed off by the cleaning brush are timely adsorbed and collected by the dust suction component to further improve the cleaning quality of the pressure roller surface.

[0010] The beneficial effects of the utility model are:

[0011] The utility model provides a scraper, and drives the two pressing rollers to rotate through a driving motor. The two rotating pressing rollers cooperate with the scraper, and the scraper scrapes and cleans the dust and lint adhered to the surface of the rotating pressing roller, effectively avoiding excessive debris adhering to the surface of the pressing roller to affect the pre-pressing quality, and there is no need to stop the machine for manual cleaning, thereby improving the processing efficiency;

[0012] The utility model provides a cleaning component, a cleaning brush, and a dust suction component. The cleaning component drives the brush to move back and forth and cleans the scraper surface back and forth. Excessive dust and lint are accumulated on the scraper surface, thereby further improving the cleaning effect on the roller surface. The dust suction component timely absorbs and collects dust and debris in the dustproof box, thereby reducing the possibility that the cleaned dust and debris will fall back on the roller, thereby further ensuring the cleaning effect on the roller surface.

[0013] The utility model arranges a chain, a driven sprocket and a driving sprocket. When a driving motor drives two pressure rollers to rotate, the pressure roller drives the driving sprocket to rotate. The driving sprocket drives the reciprocating screw rod to rotate through the chain and the driven sprocket. Only one motor is used to drive multiple structures to operate, thus saving equipment cost and effectively utilizing energy. BRIEF DESCRIPTION OF THE DRAWINGS
