Description

Technical Field

[0001] This invention relates to the field of spunlace nonwoven fabric processing technology, specifically to a spunlace nonwoven fabric combing equipment and process. Background Technology

[0002] Spunlace nonwoven fabric is made by spraying high-pressure micro-jet water onto one or more layers of fiber web, causing the fibers to entangle together and thus strengthening the web to a certain strength. The resulting fabric is called spunlace nonwoven fabric. Its fiber raw materials are widely available, including polyester, Tencel, silk, seaweed fiber, etc. It can be used in medicine, such as medical curtains and surgical gowns, surgical drapes, medical bandages, medical gauze, aviation wipes, and clothing linings, among other applications. Spunlace nonwoven fabric has good flexibility, high strength, better moisture absorption, and better breathability compared to ordinary nonwoven fabrics.

[0003] When processing nonwoven fabrics, they need to be combed. The main purpose of combing is to comb the messy fiber bundles into single fibers, form a web on the conveyor belt, and ensure the uniformity of the web. The quality of the combing determines the forming quality of the nonwoven fabric.

[0004] Existing carding mechanisms cannot collect the combed fibers during the carding process. Therefore, a spunlace nonwoven fabric carding equipment and process is proposed. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the above and / or existing spunlace nonwoven fabric combing equipment and processes, the present invention is proposed.

[0007] Therefore, the purpose of this invention is to provide a spunlace nonwoven fabric spunlace carding equipment and process. When conveying nonwoven fabric fibers, a drive component drives a carding roller to card the fibers. During carding, the hooked fibers are rolled onto the carding roller, and a scraping component scrapes the fibers off the carding roller. When the carding roller rotates, a transmission mechanism synchronously drives a cleaning component to clean the fibers on the scraping component. At the same time, the transmission mechanism drives a negative pressure mechanism to work, so that the dust collection mechanism absorbs the fibers scattered during the carding process under negative pressure. This recovers the fibers while preventing them from scattering and affecting the respiratory health of the workers.

[0042] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0043] This invention provides a hydroentangled nonwoven fabric carding device and process. During the conveying of nonwoven fibers, a drive component drives a carding roller to card the fibers. During carding, hooked fibers are rolled onto the carding roller, and a scraper component scrapes the fibers off the roller. As the carding roller rotates, a transmission mechanism synchronously drives a cleaning component to clean the fibers from the scraper component. Simultaneously, the transmission mechanism drives a negative pressure mechanism, causing a dust collection mechanism to absorb fibers dispersed during carding under negative pressure. This recovers the fibers while preventing them from affecting the respiratory health of workers. Please refer to [link to relevant documentation]. Figures 1-8 It includes: a combing mechanism 100, a scraping component 200, a transmission mechanism 300, a cleaning component 400, a dust collection mechanism 500, and a negative pressure mechanism 600.

[0044] The carding mechanism 100 includes a conveyor table 110, a frame 120, a carding roller 130, a drive component 140, and a first pulley 150.

[0053] The suction trough 520 is mounted on the conveyor table 110 on both sides by brackets. Figure 1As shown, the suction slot 520 draws in air and absorbs the fibers floating in the air. The fibers enter the dust collection box 540 through the suction pipe 510 and are blocked by the filter plate 550 to prevent the fibers from escaping.

[0054] A negative pressure mechanism 600 is mounted on and connected to the vacuuming mechanism 500. The negative pressure mechanism 600 includes a fan shaft 610, an impeller 620, a fourth pulley 630, and a second belt 640. The fan shaft 610 is rotatably connected to the flared end 530. One end of the fan shaft 610 is equipped with the impeller 620, and the other end is equipped with the fourth pulley 630. The second belt 640 connects the fourth pulley 630 to the third pulley 640.

[0055] The third pulley 340 drives the fourth pulley 630 to rotate via the second belt 640. The fourth pulley 630 drives the impeller 620 to rotate via the wind shaft 610. The impeller 620 drives the airflow, causing the negative pressure mechanism 600 to generate negative pressure for air intake.

[0056] The bottom of the scraper 210 contacts the carding roller 130, and the top of the scraper 210 contacts the cleaning roller 410, which facilitates the processing of fibers by the cleaning roller.

[0057] A protective shell 700 is installed on the outside of the upright 120 to protect the transmission structure.

[0058] A process for a hydroentangled nonwoven fabric combing equipment includes the following steps:

[0059] Step 1: Start the conveyor 110 and place the limit switch on the conveyor 110 to carry out the conveying;

[0060] Step 2: Start the drive unit 140, the carding roller 130 rotates, the carding roller 130 cards the fiber, some fibers are caught on the carding roller 130 during carding, the carding roller 130 drives the fiber to rotate, and the limit conveyor is delivered to the scraping unit 200. At the same time, the cleaning unit 400 cleans the fiber on the scraping unit 200.

[0061] Step 3: Simultaneously, the negative pressure mechanism 600 is activated, which generates negative pressure in the dust collection mechanism 500 to absorb the fibers scattered during the combing process. The absorbed fibers are then stored in the dust collection box 540.

[0062] In practical use, fibers are placed on the conveyor table 110 for conveying. The drive unit 140 drives the carding roller 130 to rotate, using the barbs on the outside of the carding roller 130 to card the fibers. The fibers are wrapped around the carding roller 130, and the scraper 210 scrapes off the fibers wrapped around the outside of the carding roller 130. The carding roller 130 synchronously drives the first pulley 150 to rotate. The first pulley 150 drives the second pulley 320 to rotate via the first belt 330. The second pulley 320 synchronously drives the first gear 310 and the third pulley 340 to rotate. The first gear 310 meshes with and drives the second gear 420 to rotate. 420 synchronously drives the cleaning roller 410 to rotate. The cleaning roller 410 cleans the fibers on the scraper component 200. The cleaning roller 410 can be removed from the U-shaped groove 122 to complete the cleaning. The third pulley 340 drives the fourth pulley 630 to rotate through the second belt 640. The fourth pulley 630 drives the impeller 620 to rotate through the air shaft 610. The impeller 620 drives the airflow, so that the negative pressure mechanism 600 generates negative pressure to draw in air. The air suction groove 520 draws in air and absorbs the fibers floating in the air.
