Description

Technical Field

[0001] This application relates to the field of fiber processing, and more specifically to an apparatus and method for preparing a type of grass thread. Background Technology

[0002] Various natural grasses, vines, and other materials contain natural fibers. These natural fibers can be spun into grass-like threads from natural grass-like raw materials, thus creating handmade grass-woven products. These products possess a certain strength and softness, and have a thread-like shape. Their thickness is between that of ordinary yarn and rope, while their twist is generally lower than that of yarn.

[0003] The raw materials for ordinary spinning are natural fibers or chemical fibers. Natural fibers include, but are not limited to, cotton, linen, silk, and wool. Fiber is a relatively flexible, fine, and long material, with an aspect ratio generally greater than 1000:1. Typical textile fibers have diameters ranging from a few micrometers to tens of micrometers, lengths exceeding 25 mm, and linear densities on the order of 10 g / mm². Cotton yarn typically has a diameter of around 0.13–0.28 mm, while yarns made from chemical fibers are even finer. Ordinary ropes generally have a diameter greater than 2 mm.

[0004] In existing technologies, the processing of these natural fibers is all done by hand. Existing non-handmade processing methods for these natural fibers only produce ropes that are too thick, unsuitable for weaving, or with very poor weavability; specifically, they are thick in diameter, have many defects, and are too stiff. Such ropes do not meet the requirements for woven products, especially for bags woven from straw.

[0005] Therefore, there is a need for a manufacturing apparatus and method that does not involve manual processing of these natural fibers. Summary of the Invention

[0006] On the one hand, this application provides a device for preparing grass-like threads.

[0007] In some embodiments, the preparation apparatus of this application includes a rounding mechanism. In some embodiments, the preparation apparatus of this application includes multiple rounding mechanisms. In some embodiments, the rounding mechanism of this application includes a first hollow shaft sleeved on the travel path of the material, and a first pair of rollers clamped in a first direction of the travel path relative to the first hollow shaft and drively connected to the first hollow shaft.

[0008] In some embodiments, the preparation apparatus of this application includes a twisting mechanism. In some embodiments, the twisting mechanism of this application includes a second hollow shaft sleeved on a first direction of the travel path relative to a first pair of rollers, and a second pair of rollers clamped on the first direction of the travel path relative to the second hollow shaft and drively connected to the second hollow shaft.

[0009] In some embodiments, the fabrication apparatus of this application includes a wire storage device disposed in a first direction relative to the second roller pair along the travel path. In some embodiments, the wire storage device of this application includes a shaft, a wire puller, and a wire storage drum connected to the shaft. In some embodiments, the wire storage drum of this application is sleeved on the shaft. In some embodiments, the wire puller of this application is sleeved on a bearing, and the bearing is sleeved on the shaft.

[0010] In some embodiments, the first hollow shaft of this application is used to allow material to pass through it. In some embodiments, the first pair of rollers of this application is used to roll and rotate the material from the first hollow shaft. In some embodiments, the second hollow shaft of this application is used to allow material from a plurality of first pairs of rollers to pass through it. In some embodiments, the second pair of rollers of this application is used to roll and rotate the material from the second hollow shaft. In some embodiments, the wire puller of this application is used to allow material from the second pair of rollers to pass through the wire puller. In some embodiments, the wire storage drum of this application is used to wind material from the wire puller onto it.

[0011] In some embodiments, the first roller pair of this application is configured to rotate about the extension direction of the first hollow shaft as a rotation axis during rolling. In some embodiments, the second roller pair of this application is configured to rotate about the extension direction of the second hollow shaft as a rotation axis during rolling. In some embodiments, the shaft of this application is configured to rotate at a first speed. In some embodiments, the wire storage drum of this application is configured to rotate at a first speed. In some embodiments, the wire puller of this application is configured to rotate at a second speed higher than the first speed. In some embodiments, the first roller pair of this application is configured to rotate at a first speed. In some embodiments, the second roller pair of this application is configured to rotate at a first speed.

[0012] On one hand, this application provides a method for preparing grass-like thread, comprising: material passing through a first hollow shaft; material from the first hollow shaft being pressed and rotated by a first pair of rollers; a plurality of materials from the first pair of rollers passing through a second hollow shaft; and a plurality of materials from the second hollow shaft being pressed and rotated by a second pair of rollers at a third speed.

[0013] In some embodiments, the rotation of the first roller pair of this application includes the first roller pair rotating about the extension direction of the first hollow shaft as a rotation axis during rolling. In some embodiments, the rotation of the second roller pair of this application includes the second roller pair rotating about the extension direction of the second hollow shaft as a rotation axis during rolling. In some embodiments, the rotation of the first roller pair of this application is at a third speed. In some embodiments, the rotation of the second roller pair of this application is at a third speed.

[0014] In some embodiments, the method of this application further includes the material being pressed and rotated by the second rollers passing through a wire feeder and wound onto a wire storage drum. In some embodiments, the wire storage drum of this application rotates at a third speed, and the wire feeder rotates at a fourth speed higher than the third speed.

[0015] On the one hand, this application provides the apparatus for preparing grass-like threads, and its use in carrying out the method for preparing grass-like threads.

[0016] On the one hand, this application provides grass-like threads prepared by the preparation apparatus and preparation method of this application.

[0017] In some embodiments, the apparatus and method of this application enable the processing of these natural fibers to be done without manual labor, solving the technical problem of how to process such natural fibers without manual labor, improving efficiency and saving manpower. The grass-like yarn produced by the apparatus and method of this application has a suitable thickness and is rounded, making it suitable for weaving textiles, such as bags. The method of this application enables fully automated and mechanized production of grass-like yarn.

[0018] In some embodiments, by feeding the grass-like material into a rounding mechanism, this application can reduce surface defects and change its cross-section from the inherent various shapes of the grass-like material (e.g., raffia with a thickness of about 0.15 mm and a width of about 4 mm has a strip-shaped cross-section, while cattail has a semi-circular strip-shaped cross-section) to a circle. The rounding process in some embodiments of this application can avoid problems such as folding and bulging, and uncomfortable yarn surface caused by directly splicing the grass-like material. Furthermore, the splicing process in some embodiments of this application can strengthen the grass-like yarn.

[0019] In some embodiments, this application enhances the strength of grass-like yarn by feeding the grass-like material into the twisting mechanism. Typical single-strand grass-like yarn has relatively low strength because it relies on self-twisting and friction to form the yarn, and the number of twists per unit length cannot be too high, otherwise it will curl. By feeding the grass-like material into the twisting mechanism, the strength of the grass-like yarn can be enhanced.

[0020] In some embodiments, this application, through the combination of a twisting mechanism and a yarn storage device, can maintain the twist of the grass-like yarn while storing it. The grass-like yarn with maintained twist can be used for subsequent processing, such as weaving shopping bags, resulting in superior strength and other technical benefits.

[0021] In some embodiments, the grass-like yarn produced by the method of this application, used for example to weave shopping bags, possesses natural and environmentally friendly characteristics that most ordinary shopping bags (plastic bags, non-woven bags, canvas bags, paper bags) currently on the market cannot achieve. Furthermore, compared to commercially available handmade natural bags (bags) such as bamboo baskets and straw bags, it is lighter and thinner, with a fabric density between that of ordinary shopping bags and handmade natural bags. Shopping bags made from grass-like yarn can fall into the category of disposable shopping bags, do not require a very dense texture structure, only need to fulfill their function under a certain load, and can be recycled through various methods. They can be collected for use as livestock feed on farms, shredded and used as fertilizer in fields, or even burned directly as fuel. Attached Figure Description

[0041] To further illustrate the technical means and effects adopted by this application in order to achieve the intended purpose, the specific implementation methods, structures, features and effects according to this application are described in detail below with reference to the accompanying drawings and preferred embodiments:

[0042] Please refer to Figure 1A This is a schematic diagram of the structure of the preparation apparatus 1 in some embodiments. The preparation apparatus 1 includes a rounding mechanism 20, a twisting mechanism 30, and a thread storage device 40. In this application, the term "grass-like thread" refers to thread formed from the fibers of the roots, stems, and leaves of herbaceous plants or vines. In this application, the term "grass-like material" refers to material including the fibers of the stems of herbaceous plants or vines, particularly materials mainly composed of the fibers of the roots, stems, and leaves of herbaceous plants or vines. In some embodiments, the grass-like material of this application is natural grass-like material, and the grass-like thread of this application is natural grass-like thread.

[0043] Please refer to Figure 1B ,for Figure 1A The specific structure is omitted to show the diagram of the travel route 5. The rounding mechanism 20, the twisting mechanism 30, and the wire storage device 40 are located on the travel route 5. In this application, the travel route 5 refers to the route that the forage material is expected to travel in the preparation apparatus 1. That is, in the preparation apparatus 1, the forage material can sequentially pass through the rounding mechanism 20, the twisting mechanism 30, and the wire storage device 40 along the travel route 5 in the direction of travel 53 to form wire.

[0044] The twisting mechanism 30 twists multiple strands of forage into a single thread. That is, in some embodiments, the travel path 5 includes multiple first travel paths 51 located in the direction opposite to the travel direction 53 of the twisting mechanism 30, including the travel path 5 within the rounding mechanism 20; and, for example, one, second travel path 52 located in the twisting mechanism 30 and in the direction opposite to the travel direction 53, including the travel path 5 within the twisting mechanism 30 and the thread storage device 40. Meanwhile, the preparation apparatus 1 may, for example, correspondingly include multiple rounding mechanisms 20. Including... Figure 1A , Figure 1B In some embodiments of the present invention, the travel route 5 includes two first travel routes 51, namely, the twisting mechanism 30 twists two strands of forage into a single thread. However, this application is not limited to this. Those skilled in the art should be able to select the desired number of strands of forage, such as two-strand, three-strand, or four-strand forage, according to actual needs, and twist them into a single thread. Correspondingly, the travel route 5 includes a corresponding number of first travel routes 51, and the preparation device 1 includes a corresponding number of rounding mechanisms 20.

[0045] Please refer to Figure 2 This is a schematic diagram of the rounding mechanism 20 in some embodiments of this application. The rounding mechanism 20 is used to prepare grass-like material into single-strand grass-like yarn. Through the rounding mechanism 20, grass-like material can be prepared into single-strand grass-like yarn with a smooth surface and an approximately circular cross-section, thereby facilitating the subsequent further preparation of the single-strand grass-like yarn into grass yarn. In some embodiments, the rounding mechanism 20 includes a first hollow shaft 22 sleeved on the travel path 5. In some embodiments, the travel path 5 passes through the first hollow shaft 22. In some embodiments, the rounding mechanism 20 includes a first pair of rollers 23 clamped on the travel path 5 in a travel direction 53 relative to the first hollow shaft 22. In some embodiments, the first pair of rollers 23 includes at least two rollers, respectively disposed on two opposite sides of the travel path 5. In some embodiments, the first hollow shaft 22 is drive-connected to the first pair of rollers 23. In some embodiments, the first hollow shaft 22 is drive-connected to the first pair of rollers 23 via a bevel gear 24. In some embodiments, the transmission connection between the first hollow shaft 22 and the first roller pair 23 allows the first roller pair 23 to rotate circumferentially while rolling along its extension direction, for example, in the rolling direction 55. This means it rotates along the extension direction of the first hollow shaft 22, for example, in the rotation direction 54. In some embodiments, the first roller pair 23 is driven to rotate by a bevel gear 24. In some embodiments, the bevel gear 24 and / or the first roller pair 23 can be driven to rotate by a motor. In some embodiments, a feeding device can be provided on the side of the first hollow shaft 22 opposite to the travel direction 53 for feeding material to the first hollow shaft 22.

[0046] In some embodiments, when the grass-like material from the first hollow shaft 22 passes between the two rollers of the first roller pair 23, the grass-like material is driven to rotate as the first roller pair 23 rotates along the extension direction of the first hollow shaft 22 while rolling the grass-like material. That is, the grass-like material exiting the first roller pair 23 is rotating. In some embodiments, the grass-like material passing between the two rollers of the first roller pair 23 during travel is also driven to rotate by the first roller pair 23, thus being simultaneously rolled and rotated by the first roller pair 23. Therefore, the first roller pair 23 can round the grass-like material, forming a single strand of grass-like material. In some embodiments, the grass-like material between the first hollow shaft 22 and the first roller pair 23 rotates simultaneously with the rotation of the first roller pair 23. In some embodiments, the grass-like material rotates about the travel path 5 as the axis of rotation, for example, rotating in the direction of rotation 54. In some embodiments, the outer shell of the rounding mechanism 20 also rotates simultaneously with the rotation of the first roller pair 23.

[0047] Please refer to Figure 3A , 3B The diagram below shows the structure of the twisting mechanism 30 and the thread storage device 40 in some embodiments of this application. Please refer to the diagram below. Figure 1A , Figure 3A The twisting mechanism 30 is used to twist multiple single strands of grass-like yarn from multiple rounding mechanisms 20 to prepare grass-like yarn. In some embodiments, the twisting mechanism 30 includes a second hollow shaft 32 sleeved on the travel path 5 relative to the travel direction 53 of the rounding mechanism 20. In some embodiments, the travel path 5 passes through the second hollow shaft 32. In some embodiments, the twisting mechanism 30 includes a second pair of rollers 33 clamped on the travel path 5 relative to the travel direction 53 of the second hollow shaft 32. In some embodiments, the second pair of rollers 33 includes at least two rollers, respectively disposed on two opposite sides of the travel path 5. In some embodiments, the second hollow shaft 32 is drive-connected to the second pair of rollers 33. In some embodiments, the second hollow shaft 32 is drive-connected to the second pair of rollers 33 via a bevel gear 34. In some embodiments, the transmission connection between the second hollow shaft 32 and the second roller pair 33 allows the second roller pair 33 to rotate circumferentially while rolling along its extension direction, for example, in rolling direction 57, i.e., rotating along the extension direction of the second hollow shaft 32, for example, in rotation direction 56. In some embodiments, the second roller pair 33 is driven to rotate by a bevel gear 34. In some embodiments, the bevel gear 34 and / or the second roller pair 33 can be driven to rotate by a motor.

[0048] In some embodiments, multiple strands of single-strand grass-like yarn from multiple rounding mechanisms 20 converge and enter the second hollow shaft 32 at the inlet 31. In some embodiments, as the multiple strands of single-strand grass-like yarn from multiple rounding mechanisms 20 pass through the second hollow shaft 32, the multiple strands of single-strand grass-like yarn exiting the second roller pair 33 rotate along the extension direction of the second hollow shaft 32 while simultaneously rolling the grass-like material. In some embodiments, the multiple strands of single-strand grass-like yarn passing between the two rollers of the second roller pair 33 are driven to rotate by the second roller pair 33, thereby being simultaneously rolled and rotated by the second roller pair 33. Thus, the second roller pair 33 can splice the multiple strands of single-strand grass-like yarn from multiple rounding mechanisms 20 to form grass-like yarn. In some embodiments, the multi-strand single-strand grass-like material from the second hollow shaft 32, such as the inlet 31 of the second hollow shaft 32, to the second roller pair 33 rotates circumferentially as the second roller pair 33 rotates. Simultaneously, the single-strand grass-like material before the inlet 31 of the second hollow shaft 32 does not rotate circumferentially with the rotation of the second roller pair 33, thereby splicing the multi-strand single-strand grass-like material from the inlet 31 of the second hollow shaft 32 to the second roller pair 33. In some embodiments, the grass-like material rotates about the travel path 5 as a rotation axis, for example, in a rotation direction 56. The rotation direction 54 and rotation direction 56 can be the same rotation direction, specifically, the same direction viewed from the travel direction 53 along the travel path 5, for example, both clockwise or both counterclockwise. In some embodiments, the grass-like material from the second roller pair 33 then enters the storage thread device 40. In some embodiments, a fixing device 35 may be provided on the second hollow shaft 32 to fix the second hollow shaft to the ground or any other surface or object, so that the second hollow shaft 32 remains stationary, thereby allowing the second roller pair 33 to rotate while rolling. In some embodiments, as the second roller pair 33 rotates, the housing of the twisting mechanism 30 also rotates, such as... Figure 3B As shown.

[0049] Please refer to Figure 4A , 4B The diagrams shown are schematic and exploded views of the storage line device 40 in some embodiments of this application. Please refer to them as well. Figure 1AFigure 4 shows that in some embodiments, the wire storage device 40 includes a shaft 45, a bearing 43 sleeved on the shaft 45, a wire puller 44 sleeved on the bearing 43, and a wire storage cylinder 46 sleeved on the shaft 45, including a first wire storage portion 461 and a second wire storage portion 462. In some embodiments, the shaft 45 is drivenly connected to the bearing 43. In some embodiments, the shaft 45 is drivenly connected to the wire storage cylinder 46. In some embodiments, the bearing 43 is drivenly connected to the wire puller 44. In some embodiments, the wire storage device 40 further includes a base 41 and a bearing 42 disposed inside the base 41, with the wire puller 44 located between the bearing 43 and the bearing 42. Please refer to... Figure 5A , 5B Figures 5C and 5C are schematic diagrams of the wire puller 44 from different perspectives in some embodiments of this application. In some embodiments, the wire puller 44 is provided with a wire pulling hole 441, through which a single strand of grass-like thread from the first roller pair 23 passes through the wire puller 44.

[0050] In some embodiments, shaft 45 and the cable storage drum 46 are driven to rotate by a first motor 481. In some embodiments, the cable puller 44 is driven to rotate by a second motor 482, for example, via a belt drive. Please refer to [reference needed]. Figure 6A , 6B This is a schematic diagram illustrating the transmission connection between the wire storage drum 46 and the first motor 481 in some embodiments of this application. Specifically, in some embodiments, the first motor 481 is located on the slide rail 484, and during wire storage, as... Figure 6A As shown, the first motor 481 is in a first state of being connected to the wire storage drum 46 in a transmission manner, driving the wire storage drum 46 and the shaft 45 to rotate; while during wire feeding, as... Figure 6B As shown, the first motor 481 is in a second state separated from the wire storage drum 46, preventing it from driving the wire storage drum 46 and the shaft 45 to rotate, thus preventing the wire storage drum 46 and the shaft 45 from rotating. In some embodiments, the first motor may be provided with, for example, a transmission rod 483, to abut against one end of the wire storage drum 46 in the first state, so that the first motor 481 can rub against and drive the wire storage drum 46.

[0051] In some embodiments, the bearing 43 located between the thread puller 44 and the shaft 45 allows the thread puller 44 to rotate at a higher speed than the shaft 45. In some embodiments, the shaft 45 drives the thread reservoir 46 to rotate such that the rotational speed of at least one of the first thread storage portion 461 and the second thread storage portion 462 is the same as the rotational speed of the ray from the second roller pair 33. In some embodiments, the rotational speed of the shaft 45 is the same as the rotational speed of the thread reservoir 46. In some embodiments, the rotational speed of the thread puller 44 is higher than the rotational speed of the thread reservoir 46. In some embodiments, due to the speed difference between the thread puller 44 and the thread reservoir 46, the ray from the thread puller 44 is wound around the thread reservoir 46, for example, around at least one of the first thread storage portion 461 and the second thread storage portion 462. In some embodiments, the thread wound around the first thread storage portion 461 slides down to the second thread storage portion 462 and is arranged on the second thread storage portion 462.

[0052] The twisting mechanism 30 and the thread storage device 40 of this application enable the rotational speed of at least one of the first thread storage section 461 and the second thread storage section 462 to match the rotational speed of the straw-like thread from the second roller pair 33. This allows the twist of the straw-like thread wound on at least one of the first thread storage section 461 and the second thread storage section 462 to be maintained, preventing it from unraveling. With the twist of the straw-like thread stored in the thread storage spool 46 maintained, it can be further unwound to manufacture related articles using the twist-maintained straw-like thread.

[0053] In some embodiments, the wire storage and dispensing device 40 further includes a limiting ring 47. In some embodiments, the limiting ring 47 can hold the wire on the second wire storage portion 462. In some embodiments, the limiting ring 47 further includes a limiting hole 471, which allows a single strand of grass-like wire from the second wire storage portion 462 to be pulled out through the limiting hole 471 during wire dispensing, thereby achieving a limiting effect.

[0054] In some embodiments, this application provides a method for preparing grass-like threads.

[0055] The first roller is moved and rotated in the direction of rotation 54, for example, by a motor driving the first roller to move and rotate the first roller to rotate the first roller to rotate the first roller to rotate the first roller to rotate the first roller to rotate the first roller to rotate the first roller to form a single strand of grass. The grass passes through the first hollow shaft 22 and is then rolled and rotated by the first roller to rotate the first roller to rotate the first roller to form a single strand of grass.

[0056] The second roller pair 33 is rolled and rotated in the rotation direction 56, for example, by a motor driving the second roller pair 33 to roll and rotate. Multiple strands of grass-like yarn from multiple first roller pairs 23 pass through the second hollow shaft 32, and are then rolled and pressed by the second roller pair 33, which is rolled and rotated in the rotation direction 56, thereby being spliced ​​to obtain grass-like yarn.

[0057] The shaft 45 and the wire storage drum 46 are rotated, for example, by a motor, such as by a motor 481. Simultaneously, the wire feeder 44 is rotated, for example, by a motor, such as by a motor 482. The speed at which the wire feeder 44 rotates is higher than the speed at which the shaft 45 and the wire storage drum 46 rotate. The grass-like thread obtained after being rolled by the second roller pair 33 is wound onto the wire storage device 40. The grass-like thread passes through the wire feeder 44 of the wire storage device 40 via the wire feeder hole 441, and then is wound onto the wire storage drum 46 of the wire storage device 40, for example, onto at least one of the first wire storage portion 461 and / or the second wire storage portion 462 of the wire storage device 40. The rotation speed of the shaft 45 and the wire storage drum 46 is the same as that of the second roller pair 33. Thus, the straw-like thread from the second roller pair 33 can maintain its twist on the thread storage device 40, such as the thread storage drum 46.

[0058] In some embodiments, the grass-like yarn produced by the apparatus or method of this application has a diameter of approximately 0.5 mm to 1.5 mm, for example, 0.8 mm to 1.2 mm, and more specifically, about 1 mm. In some embodiments, the grass-like yarn produced by the apparatus or method of this application has a twist of 10–80 twists per 10 cm. In some embodiments, the grass-like yarn produced by the apparatus or method of this application has a smooth, rounded surface without burrs. In some embodiments, the single strand of grass-like yarn obtained after rounding, such as... Figure 7 As shown; the grass-like thread obtained after splicing, as... Figure 8 As shown.

[0059] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
