Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically a nonwoven fabric pre-compression mechanism. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, and needle-punched non-woven fabric, is made of polyester fiber. It is produced through a needle-punching process, which can produce different thicknesses, feels, and hardnesses. Non-woven fabric is characterized by moisture resistance, breathability, flexibility, lightness, flame retardancy, non-toxicity, odorlessness, low price, and recyclability. It can be used in various industries, such as sound insulation, heat insulation, heating elements, masks, clothing, medical materials, and filling materials. Non-woven fabric has no warp or weft threads, making it very convenient to cut and sew. It is also lightweight and easy to shape, making it popular among handicraft enthusiasts. Because it is a fabric that does not require spinning and weaving, it is made by arranging short or long textile fibers in a directional or random manner to form a web structure, which is then reinforced by mechanical, thermal bonding, or chemical methods.

[0003] Nonwoven fabric, as a new type of environmentally friendly material, is widely used in many industries due to its characteristics such as moisture resistance, breathability, flexibility, lightness, flame retardancy, and non-toxicity and odorlessness. In the production process of nonwoven fabric, pre-compression is a key step, which has an important impact on the flatness, density, and hand feel of the nonwoven fabric. However, it has been found in the use of existing nonwoven fabric pre-compression mechanisms that it is not convenient to adjust the pressure. If the pressure is too high or too low, it will lead to uneven density of the pre-compressed nonwoven fabric, which cannot meet the needs of users. Therefore, those skilled in the art have provided a nonwoven fabric pre-compression mechanism to solve the problems mentioned in the background art. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This nonwoven fabric pre-compression mechanism, through the coordinated use of an adjusting screw, a cylindrical bearing, and a threaded sleeve, transmits pressure to the spring while simultaneously regulating its pressure. Utilizing the cooperation of the spring, pressure roller, sliding rod, and sliding hole, it concentrates and neutralizes the pressure at the pressure roller and spring, while also positioning the pressure plate. This prevents uneven density of the pre-compressed nonwoven fabric due to excessive or insufficient pressure. The coordination of the drive motor, threaded rod, threaded hole, and connecting frame facilitates the reciprocating motion of the pressure roller, achieving the purpose of pre-compressing the nonwoven fabric.
