Technical Field
[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a high-efficiency spunbond nonwoven fabric production device. Background Technology
[0002] High-efficiency spunbond nonwoven fabric production equipment is the core equipment for achieving large-scale, high-quality production of spunbond nonwoven fabrics. Its design must balance the efficiency and stability of key processes such as raw material processing, spinning, drawing and web laying, thermal bonding, and winding and slitting, as nonwoven fabrics are increasingly widely used in various fields. In the medical field, they are used to make surgical gowns, masks, and bandages; in the hygiene field, they are used to produce sanitary napkins and diapers; and in the clothing field, they can be used as linings and thermal insulation materials. Different applications have different requirements for the specifications and dimensions of nonwoven fabrics, which necessitates high-efficiency spunbond nonwoven fabric slitting machines to cut the produced wide-width nonwoven fabrics into products of various specific sizes.
[0003] Existing patent document CN221142258U discloses a slitting device for producing spunbond bicomponent fiber nonwoven fabric, comprising: a mounting box; and a cleaning assembly. The cleaning assembly is slidably connected to the inner side of the mounting box. The cleaning assembly includes two sliders, the inner sides of which are slidably connected to the inner side of the mounting box. A first cleaning roller is rotatably connected to one side of each slider, and a spring is fixedly connected to the top of each slider. This utility model provides a slitting device for producing spunbond bicomponent fiber nonwoven fabric. The first and second cleaning rollers facilitate the cleaning of impurities from the top and bottom of the nonwoven fabric. The combined use of the springs and sliders facilitates the cleaning of nonwoven fabrics of different sizes. The structure is simple and practical, making it very convenient for cleaning dust and impurities from the surface of nonwoven fabrics, reducing the processing steps, and thus greatly reducing the cost of nonwoven fabric production.
[0004] However, existing high-efficiency spunbond nonwoven fabric production equipment cannot flexibly and conveniently adjust the slitting spacing of the nonwoven fabric in practical applications. When slitting softer nonwoven fabrics, unreasonable slitting spacing settings can easily lead to problems such as fabric shifting and wrinkling during the slitting process, affecting not only the slitting accuracy but also significantly reducing the slitting efficiency. At the same time, the coordination between the pressing, feeding, and slitting stages of the equipment is insufficient, and the operation of pressing and fixing the fabric is not flexible enough. It cannot complete the pressing action in a timely manner according to the conveying length of the nonwoven fabric and the slitting requirements, further affecting the overall slitting process. To address these issues, we propose a high-efficiency spunbond nonwoven fabric production equipment. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency spunbond nonwoven fabric production apparatus to solve the problems mentioned in the background section.

[0014] This utility model provides a high-efficiency spunbond nonwoven fabric production device, which has the following beneficial effects:
[0015] This high-efficiency spunbond nonwoven fabric production device, equipped with an adjusting groove, a pressing frame, a slider, an adjusting nut seat, a forward screw, and a reverse screw, operates as follows: The operator installs the nonwoven fabric on the feeding cylinder, then inserts it between the feeding shafts, positioning it between the partition and the pressing cylinder. The drive motor is then started, driving the first and second transmission wheels via a transmission belt. Simultaneously, the feeding cylinder and feeding shaft rotate, conveying the nonwoven fabric to the second pressing frame on the right. Once the cutting length is reached, the adjusting rod, through the adjusting sleeve, drives the pressing cylinder... The nonwoven fabric is pressed down, and the slitting motor drives the slitting screw to rotate. The slitting nut seat, due to the rotation direction of the slitting screw, drives the slitting blade to move back and forth, thus cutting the nonwoven fabric.

The adjusting motor drives the forward and reverse screws to rotate, and the two adjusting nuts seat, due to the rotation direction of the forward and reverse screws, drive the fabric pressing frame to move inward or outward through the slider and adjusting groove, thereby adjusting the slitting gap of pressing down the nonwoven fabric. Therefore, it is convenient for the operator to adjust the slitting gap, thus improving the slitting efficiency. Attached Figure Description

[0025] Furthermore, a motor frame 102 is welded to the front of the slitting body 101, and a drive motor 103 is mounted on the front of the motor frame 102. The drive end of the drive motor 103 is connected to a transmission toothed belt 104 through a drive wheel. When the drive motor 103 is started, the drive motor 103 drives two transmission wheels to rotate through the transmission toothed belt 104.
