Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric storage and extraction devices, and in particular to a nonwoven fabric pull tube. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is not made of interwoven or woven yarns, but rather by bonding fibers together directly through physical or chemical methods. It has the characteristics of being soft, breathable, waterproof, and environmentally friendly, and is widely used in medical, hygiene, packaging, decoration, and agricultural fields. It is a common and practical material in daily life.

[0003] As disclosed in Chinese Patent No. CN216417006U, this utility model's pull-out tube for nonwoven fabrics is applicable to nonwoven fabrics of various thicknesses with a break-point design. When the nonwoven fabric is pulled out from the pull hole, it first reaches the pull area, then along the first gap to the tear area. At this point, the nonwoven fabric fills the tear area, and the second and third gaps also hold the nonwoven fabric in place. Pulling further upwards, when the break point is reached, force is applied from one end, and the nonwoven fabric can be easily torn without contacting unused nonwoven fabric, preventing contamination. While the pull-out tube for nonwoven fabric in the aforementioned document achieves easy tearing by holding the nonwoven fabric in place through gaps, in actual use, users often pull out too much nonwoven fabric at once due to excessive force, resulting in a waste of nonwoven fabric. This problem affects the economic efficiency and practicality of the pull-out tube during use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution: a non-woven fabric pull tube, comprising a pull tube, a top cover being movably engaged at the top of the pull tube, a rotating base being rotatably connected to the inner wall of the bottom of the pull tube, and a fabric outlet being provided on the outer side of the pull tube.

[0005] The outer side of the pull tube is equipped with a pull mechanism for quantitatively extracting non-woven fabric in an arc-shaped rotating manner.

[0006] As an improvement to the above technical solution, the pull-out mechanism includes a circular fixing block, a circular slot, a return spring, a thrust arc plate, a plastic cutting plate, a pressing plate, and a reset assembly. The circular fixing block is fixedly installed on the outside of the pull-out cylinder close to the bottom. The top of the circular fixing block has an annular inner slot, and the inner wall of the outer side of the annular inner slot has an annular outer slot. The circular slot is movably engaged in the annular inner slot. The return spring is fixedly installed on the inner wall of the outer side of the annular outer slot. The end of the return spring near the center is fixedly installed on the outer side of the circular slot. The thrust arc plate is fixedly installed on the top of the circular slot. The plastic cutting plate is fixedly installed on the end of the thrust arc plate near the fabric outlet. The outer side of the thrust arc plate, near the fabric outlet, has a telescopic slot. The pressing plate is movably engaged in the telescopic slot. The reset assembly is symmetrically fixed on the outer side of the thrust arc plate, near the upper and lower ends of the telescopic slot.

[0007] As an improvement to the above technical solution, the reset component includes a power-assisted slot block and a power-assisted spring. The power-assisted slot block is symmetrically fixedly installed on the outer side of the thrust arc plate and located near the upper and lower ends of the telescopic slot. The power-assisted slot block is slidably engaged with an auxiliary slot block. The auxiliary slot block is fixedly installed with a pressing plate. The power-assisted spring is fixedly installed on the inner wall of the power-assisted slot block on the side away from the center. The end of the power-assisted spring near the center is fixedly installed with the auxiliary slot block.

[0008] As an improvement to the above technical solution, a limiting block is fixedly installed on the top of the circular fixing block and on the clockwise side of the telescopic slot, and a fixing block is fixedly installed on the outer side of the thrust arc plate at the end away from the fabric outlet.

[0009] As an improvement to the above technical solution, the outer side of the pull-out tube is fixedly installed with multiple arc-shaped dividing strips arranged in a uniform vertical array.

[0010] The beneficial effects of this utility model are as follows: When it is necessary to extract non-woven fabric, rotating the pull mechanism on the outside of the pull tube will pull out a unit of non-woven fabric. Then, by cooperating with the break point on the non-woven fabric through the pull mechanism, the extracted non-woven fabric is torn. The pull mechanism allows the user to extract only a fixed amount of non-woven fabric at a time, preventing the user from using excessive force to extract too much non-woven fabric at once. This ensures that the extraction amount accurately matches the actual needs and avoids waste of non-woven fabric. This situation improves the economy and practicality of the pull tube in use.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0019] Reference Appendix Figure 1 ,exist Figure 1 In the diagram, 'a' points to the front view and 'b' points to the right-side view. These views are only used to understand the scheme.

[0020] Please see Figure 1-6 This utility model provides a technical solution: a non-woven fabric pull tube, including a pull tube 1, a top cover 11 is movably snapped onto the top of the pull tube 1, a rotating base 12 is rotatably connected to the bottom inner wall of the pull tube 1, and a fabric outlet 2 is opened on the outer side of the pull tube 1.

[0021] The outer side of the pull tube 1 is equipped with a pull mechanism for quantitatively extracting non-woven fabric in an arc-shaped rotating manner.

[0022] In this implementation scheme, when it is necessary to extract the non-woven fabric, the pulling mechanism on the outside of the pull tube 1 is rotated to pull out a unit of non-woven fabric. Then, the pulled-out non-woven fabric is torn by the pull mechanism engaging with the break point on the non-woven fabric. The pull mechanism allows the user to extract only a fixed amount of non-woven fabric at a time, preventing the user from using excessive force to extract too much non-woven fabric at once. This ensures that the extraction amount accurately matches the actual needs and avoids waste of non-woven fabric. This situation improves the economy and practicality of the pull tube 1 during use.

[0023] Specifically, the pull-out mechanism includes a circular fixing block 3, a circular groove 42, a return spring 43, a thrust arc plate 44, a plastic cutting plate 45, a pressing plate 47, and a return assembly. The circular fixing block 3 is fixedly installed on the outside of the pull-out cylinder 1 close to the bottom. The top of the circular fixing block 3 has an annular inner groove 4, and the inner wall of the outer side of the annular inner groove 4 has an annular outer groove 41. The circular groove 42 is movably engaged in the annular inner groove 4. The return spring 43 is fixedly installed on the inner wall of the outer side of the annular outer groove 41. One end of the spring 43 near the center is fixedly installed on the outside of the circular groove 42. The thrust arc plate 44 is fixedly installed on the top of the circular groove 42. The plastic cutting plate 45 is fixedly installed on one end of the thrust arc plate 44 near the fabric outlet 2. A telescopic groove 46 is provided on the outside of the thrust arc plate 44 near the fabric outlet 2. The pressing plate 47 is movably engaged in the telescopic groove 46. The reset assembly is symmetrically fixed on the outside of the thrust arc plate 44 and at the upper and lower ends near the telescopic groove 46.

[0024] The reset assembly includes an assisting slot block 5 and an assisting spring 51. The assisting slot block 5 is symmetrically fixedly installed on the outside of the thrust arc plate 44 and located at the upper and lower ends near the telescopic slot 46. The assisting slot block 5 is slidably engaged with an auxiliary card block, which is fixedly installed with the pressing plate 47. The assisting spring 51 is fixedly installed on the inner wall of the assisting slot block 5 on the side away from the center, and the end of the assisting spring 51 near the center is fixedly installed with the auxiliary card block.

[0025] In this embodiment, the amount of nonwoven fabric extracted each time is quantitatively controlled by the cooperation of the internal structure of the extraction mechanism to prevent the user from applying too much force and extracting too much nonwoven fabric at once.

[0026] Specifically, a limiting block 6 is fixedly installed on the top of the circular fixing block 3 and on one side of the telescopic slot 46 clockwise, and a fixing block is fixedly installed on the outer side of the thrust arc plate 44 at the end away from the fabric outlet 2.

[0027] In this embodiment, the spacing between the fixed block and the limiting block 6 is matched so that the thrust arc plate 44 can extract a certain amount of non-woven fabric each time it is rotated.

[0028] Specifically, multiple arc-shaped dividing strips 7 are fixedly installed on the outer side of the pull-out tube 1 in a uniform, vertical array.

[0029] In this embodiment, multiple arc-shaped dividing strips 7 are used to ensure that the non-woven fabric maintains a certain distance from the outer wall of the pull-out cylinder 1 when it is pulled out.

[0030] In use, place the nonwoven fabric-wrapped tube inside the pull-out tube 1 and fix it by rotating the base 12 and top cover 11. The cooperation of the base 12 and top cover 11 also ensures the stability of the nonwoven fabric during extraction and rotation. The end of the nonwoven fabric is passed through the outlet 2 and the thrust arc plate 44 to extend to the outside. When the nonwoven fabric needs to be extracted, hold the pull-out tube 1 with one hand and the thrust arc plate 44 with the other, pressing the pressure plate 4. 7. The pressing plate 47 moves closer to the center of the circle and cooperates with the arc-shaped dividing strip 7 to squeeze the non-woven fabric. The pressing plate 47 drives the assist spring 51 to extend. At this time, the thrust arc plate 44 is rotated. The thrust arc plate 44 drives the annular groove 42 to rotate along the inner groove 4 of the annular ring. When the annular groove 42 rotates, it drives the return spring 43 to deform. When the thrust arc plate 44 drives the pressing plate 47 to rotate through the telescopic groove 46, the pressing plate 47 and the arc-shaped dividing strip 7 are squeezed together. The arc-shaped separator 7 works in conjunction with the non-woven fabric extraction mechanism during rotation. When the fixed block on the outer side of the thrust arc plate 44 contacts the limit block 6, one unit of non-woven fabric is extracted. Releasing the thrust arc plate 44 and the pressing plate 47 causes the assist spring 51 to move the pressing plate 47 away from the center, contacting and squeezing the non-woven fabric. Then, the return spring 43 drives the thrust arc plate 44 to rotate in the opposite direction through the circular groove 42 to reset. After the thrust arc plate 44 is reset, the plastic cutting plate 45 engages with the break point on the non-woven fabric to tear the extracted non-woven fabric. Similarly, the extraction principle is the same for multiple units of non-woven fabric. The extraction mechanism allows the user to extract only a fixed amount of non-woven fabric at a time, preventing the user from using excessive force and extracting too much non-woven fabric at once. This ensures that the extraction amount accurately matches the actual needs and avoids waste of non-woven fabric. This improves the economy and practicality of the extraction tube 1 during use.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
