Description

Technical Field

[0001] The invention belongs to the technical field of wig production, and in particular relates to a method for manufacturing a wide-width hair bundle product. Background Art

[0002] The two ends of the amplitude hair bundle product (hereinafter referred to as the hair bundle product) 1 have an amplitude that imitates the ends of real human hair, that is, the thickness of the middle part of the hair bundle product is consistent, while the hair at the two ends of the tail gradually becomes thinner. This is because the individual hair strands that make up the hair bundle product are not of the same length. The individual hair strands all pass through the middle part of the hair bundle product to form the main part 2 of the hair bundle product; and the ends of the individual hair strands are arranged layer by layer at the two ends of the hair bundle product to form a natural effect of layered ends of the hair bundle product. The parts where the hair ends at the two ends of the hair bundle product are arranged layer by layer constitute the amplitude part 3 of the hair bundle product; and the total length of the hair bundle product is the sum of the length of the main part of the hair bundle product and twice the length of the amplitude part of the hair bundle product.

[0003] US Patent No. 10945478 discloses a hair accessory, comprising: a bound synthetic braided hair, comprising: a first bundle of synthetic hair strands having a predetermined length; and a second bundle of synthetic hair strands also having a predetermined length; wherein the center of the first bundle of synthetic hair strands and the center of the second bundle of synthetic hair strands are offset from each other by a predetermined distance; wherein the synthetic braided hair strands are folded around the waist of the synthetic braided hair strands to define a perimeter having a first end, a middle portion, and a second end, wherein the first end is co-located with the waist, and the middle portion and the second end are located at the distal end of the waist; wherein, when the synthetic braided hair strands extend from the middle portion of the perimeter to the second end, the width of the perimeter becomes narrower. A hair accessory packaging method is also disclosed, including: obtaining a first bundle of synthetic hair; obtaining a second bundle of synthetic hair; offsetting the center of the first bundle of synthetic hair from the center of the second bundle of synthetic hair by a preset distance; bundling the first bundle of synthetic hair and the second bundle of synthetic hair into a bundle of synthetic braided hair; folding the bundled synthetic braided hair around the waist of the bundled synthetic braided hair to define a periphery having a first end aligned with the waist, a middle portion, and a second end located at the distal end of the waist, wherein the width of the periphery narrows from the middle portion to the second end. It also includes obtaining: a third bundle of synthetic hair; a fourth bundle of synthetic hair; and offsetting the bundles of the third and fourth bundles of synthetic wool from the center of the first and second synthetic hair bundles toward the center of the third and fourth synthetic hair bundles to bind the third and fourth bundles of synthetic wool above the first and second bundles of synthetic wool.

[0004] However, the above patented technology has the following defects: two or more hair strands with fixed lengths are used to manufacture hair bundle products. First, during production, workers are required to scatter and pull the hair on a rake equipped with multiple rows of teeth, and reasonably control the strength and technique to obtain the amplitude and layering of the hair bundle product. This requires high skills and physical strength from the workers, and the workers are at great risk of occupational diseases. In reality, there are obviously not enough workers who meet the requirements; secondly, the natural effect of the arrangement of the ends of the hair strands in the amplitude part is insufficient, and the degree of simulation is limited. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a method for manufacturing an amplitude hair bundle product, so that the ends of the hair in the amplitude part of the amplitude hair bundle product are arranged naturally, the simulation degree is improved, and at the same time the problem of insufficient workers faced in production is solved, the workers are protected, and the occurrence of occupational diseases is avoided.

[0006] To achieve the above object, the technical solution adopted by the present invention is: a method for manufacturing a wide-width hair bundle product, comprising the following steps: Step 1: Prepare the raw hair bundle; Step 2, cutting manufacturing units: cutting one or more manufacturing units from the raw hair bundle, wherein the manufacturing units are in a trapezoidal structure; Step three: mix each manufacturing unit.

[0007] Optimally, in the step 2 of cutting the manufacturing units, one or more manufacturing units are cut out in sequence starting from the starting end of the raw hair bundle.

[0008] Optimally, the length of the long side of the trapezoidal structure of the manufacturing unit is less than the total length of the hair bundle product; the length of the corresponding amplitude of the hypotenuse of the trapezoidal structure is less than the length of the amplitude part of the hair bundle product; the manufacturing method also includes step four, dragging the manufacturing unit: dragging part of the hair at both ends of the manufacturing unit outward for a certain length until the length of the manufacturing unit reaches the total length of the hair bundle product.

[0009] Optimized, the specific operation of dragging the manufacturing unit in step 4 is: holding the middle part of the manufacturing unit, and dragging parts of the hair at both ends outward to a certain length multiple times.

[0010] Optimized, the specific operation of preparing the raw hair bundle in step 1 is: passing the starting end of the raw hair bundle through the processing baffle, the raw hair bundle is arranged between the processing baffles, and the starting end of the raw hair bundle exceeds the processing baffle by a certain length.

[0011] Optimally, the distance between the two processing baffles is adjusted according to the output of the manufacturing unit.

[0012] Optimized, the specific operation of cutting the first manufacturing unit in step 2 is: starting from the starting end of the raw hair bundle, on one side of the processing baffle, cutting from the cutting point a on one side of the raw hair bundle diagonally upward to the corresponding cutting point A on the other side of the raw hair bundle; then, on the other side of the processing baffle, cutting from the cutting point b on one side of the raw hair bundle diagonally upward to the corresponding cutting point B on the other side of the raw hair bundle; the cutting points aABb form a trapezoidal structure, i.e., the first manufacturing unit, and the first manufacturing unit cut out is disconnected from the remaining raw hair bundle, and the disconnection point is the oblique edge structure formed by the cutting point bB.

[0013] Optimized, the specific operation of cutting the second manufacturing unit in step 2 is: passing the starting end of the remaining raw material hair bundle through the processing baffle, and the remaining raw material hair bundle is arranged between the processing baffles. At this time, the starting end of the remaining raw material hair bundle is a bevel structure bB, and then, on the other side of the processing baffle, cutting from the cutting point c on one side of the raw material hair bundle to the corresponding cutting point C on the other side of the raw material hair bundle; the cutting points bBCc form a trapezoidal structure, i.e., the second manufacturing unit, and the cut second manufacturing unit is disconnected from the remaining raw material hair bundle, and the disconnection point is the bevel structure formed by the cutting point cC; and so on, repeat the operation of cutting the second manufacturing unit to obtain multiple manufacturing units.

[0014] Optimized, the cutting tools are one or more of scissors, lasers, and forging knives; the cutting method is manual or machine.

[0015] Optimized, the hypotenuse of the trapezoidal structure is one or more curves or straight lines, the part close to the long side of the trapezoidal structure or the short side of the trapezoidal structure is the starting section or the ending section, the middle part is the middle section, and the inclination and hair volume of the starting section, the ending section, and the middle section are determined according to the requirements of the amplitude part of the hair bundle product.

[0016] Optimized, step three mixing the specific operations of each manufacturing unit includes winding and unblocking, and the winding and unblocking operations are repeated multiple times.

[0017] Optimized, the specific operation of the first winding is: starting from the short side of the trapezoidal structure or the long side of the trapezoidal structure, the hair is successively wound inward into a quasi-circular hair strand; the specific operation of unblocking is: after winding, hold the middle of the quasi-circular hair strand, comb the two ends of the hair with your hands or a comb, and then let go of the quasi-circular hair strand, and the hair is naturally laid flat; the specific operation of the second winding is: starting from one side of the flatly arranged hair, the hair is successively wound inward into a quasi-circular hair strand; and then the operations of unblocking, winding, and unblocking are repeated multiple times in sequence.

[0018] Optimized, the winding method is operated manually or by machine; the dredging method is operated manually or by machine.

[0019] Optimally, the total number of winding operations is 2-8 times, and the total number of unblocking operations is 2-8 times; the length of the long side of the trapezoidal structure of the manufacturing unit, the length of the short side of the trapezoidal structure, and the corresponding amplitude length of the trapezoidal structure hypotenuse are determined according to the requirements of the amplitude part of the hair bundle product.

[0020] A quasi-trapezoidal structure means that: the upper and lower sides of the cut manufacturing unit along the length direction of the hair are nearly parallel, resembling the two parallel opposite sides of a trapezoidal structure (i.e., the long side of the quasi-trapezoidal structure and the short side of the quasi-trapezoidal structure); and the two oblique sides (i.e., the oblique sides of the quasi-trapezoidal structure) are cut at a certain angle to the length direction of the hair, resembling the two oblique sides of a trapezoidal structure.

[0021] The raw hair bundle used in the present invention has a certain length, and a trapezoidal structure manufacturing unit is directly cut out from the raw hair bundle. The two oblique sides of the trapezoidal structure are cut continuously, and the lengths of the hair involved increase successively, which is coherent. Then, after the mixing step, the hairs of different lengths in the manufacturing unit are evenly arranged in an interlaced manner. Because the two oblique sides of the trapezoidal structure are cut and formed continuously, the amplitude part formed at the tail of the hair bundle product after mixing has a more natural effect. In addition, the present invention forms the amplitude part on the basis of cutting out the oblique sides of the trapezoidal structure, and there is no need for workers to repeatedly scatter and pull the hair bundles on a rake to create the amplitude effect, which solves the problem of insufficient workers in production, protects workers, and avoids the occurrence of occupational diseases.

[0022] The raw hair bundle can be processed or unprocessed hair suitable for making hair bundle products.

[0023] The length of a manufacturing unit refers to the distance between the ends of the hair at both ends of the manufacturing unit along the length direction of the hair, that is, the total length of the manufacturing unit.

[0024] The total length of the hair bundle product is determined according to the needs of the product and the market. The number of continuous production manufacturing units is one or more, and the specific number is related to the total length of the raw hair bundle and the length of the manufacturing unit. When the total length of the raw hair bundle is long, generally 120 or even more manufacturing units can be manufactured. The manufacturing units are cut continuously, and only scraps appear at the two ends of the raw hair bundle. The rest of the parts are all made into manufacturing units, which greatly improves the utilization rate of the raw hair bundle.

[0025] The length of the long side of the trapezoidal structure of the manufacturing unit is the length of the long side of the parallel opposite sides of the trapezoidal structure. The length of the short side of the trapezoidal structure of the manufacturing unit is the length of the short side of the parallel opposite sides of the trapezoidal structure. The length of the corresponding amplitude of the hypotenuse of the trapezoidal structure is the length of the hypotenuse involving the hair along the long side of the trapezoidal structure, that is, half of the difference between the long side and the short side of the trapezoidal structure.

[0026] The length of the long side of the trapezoidal structure of the manufacturing unit can be lower than the total length of the hair bundle product, and by dragging part of the hair at both ends of the hair bundle of the manufacturing unit outward, the length of the manufacturing unit reaches the total length of the hair bundle product. After the dragging step, the hair of different lengths at the tail of the hair bundle product is arranged more naturally, with a more natural simulation effect.

[0027] When preparing the raw hair bundles in step 1, since the raw hair bundles are generally in the shape of handles or bundles, they are naturally spread out and placed between the processing baffles, which tends to be evenly arranged and is easy to operate; the starting end of the raw hair bundle exceeds the processing baffle by a certain length, which is convenient for cutting operations.

[0028] When cutting the first manufacturing unit in step 2, the hair bundle can be cut from the cutting point a on one side of the raw hair bundle to the left and upward to the corresponding cutting point A on the other side of the raw hair bundle; at the same time, the hair bundle can be cut from the cutting point b on one side of the raw hair bundle to the right and upward to the corresponding cutting point B on the other side of the raw hair bundle. It is also possible to cut from the cutting point a on one side of the raw hair bundle to the right and upward to the corresponding cutting point A on the other side of the raw hair bundle; at the same time, the hair bundle can be cut from the cutting point b on one side of the raw hair bundle to the left and upward to the corresponding cutting point B on the other side of the raw hair bundle. In short, in order to form a trapezoidal structure, aA and bB have opposite upward tilting directions. The same is true when cutting other manufacturing units.

[0029] The hypotenuse of a trapezoidal structure is cut at a certain angle to the length of the hair, and is one or more curved or straight lines. The part close to the long side or short side of the trapezoidal structure is the starting section or the ending section, and the middle part is the middle section. The inclination and hair volume of the starting section, the ending section, and the middle section are determined according to the effect and requirements of the width part of the hair bundle product. If the hypotenuse of a trapezoidal structure is three line segments, the inclination refers to the angle formed when the three lines of the starting section, the ending section, and the middle section are extended and intersect with the long side of the trapezoidal structure.

[0030] The first winding starts from the short side or long side of the trapezoidal structure, and the hair is wound inwards into a circular lock (whose cross-section is circular). At this time, the shorter or longer hair enters the hair lock, and the longer or shorter hair is surrounded on the outside; after the two ends of the hair are dredged and combed, the circular lock is put down, and the hair is naturally laid flat, and the shorter hair and the longer hair are arranged crosswise; the second winding starts from one side, and the hair is wound inwards into a circular lock. At this time, the hair on one side enters the hair lock, and the hair on the other side is surrounded on the outside; after the two ends of the hair are dredged and combed, the circular lock is put down, and the hair is naturally laid flat, and the shorter hair and the longer hair are further crossed and arranged more evenly. After multiple windings and dredging, hair of different lengths are evenly arranged, making the amplitude part of the hair bundle product more natural.

[0031] In this application, the total number of winding operations refers to the total number of winding operations, including the first winding, the second winding, and so on until each manufacturing unit is mixed; the total number of dredging operations refers to the total number of dredging operations, including the first dredging, the second dredging, and so on until each manufacturing unit is mixed.

[0032] When the total number of winding and dredging operations is 1, the effect of the amplitude part is naturally limited. As the number of times increases, the effect will naturally be better. However, after 10 times, the effect is no longer obvious and there is no need to perform winding and dredging again. Therefore, it is preferred that the total number of winding and dredging operations is 2-8 times.

[0033] The present invention, on the basis of cutting out the trapezoidal structure bevel, does not need the workers to repeatedly scatter and pull the hair bundles on the rake to create the amplitude effect; further, the present invention directly adopts the ingenious winding and unblocking techniques to make the final product effect very close to the effect of the amplitude pulled by the beautician manually, so that the amplitude part of the hair bundle product has a more natural effect. In particular, the winding and unblocking operations can not only quickly and fully mix the hair to make the product, but also have another advantage: the winding action saves time and effort, and the unblocking operation can be completed by using an ordinary hand-held comb, which is simple and easy to do without too much effort and technology, solving the problem of insufficient technical personnel in production, and protecting the workers to the greatest extent, avoiding the occurrence of occupational diseases.

[0034] In summary, the beneficial effects of the present invention are: by adopting the method of cutting the trapezoidal structure to form the amplitude part, after the mixing step, the ends of the hair strands in the amplitude part of the amplitude hair bundle product are arranged naturally, and the simulation degree is improved. At the same time, the problem of insufficient laborers in production is solved, the laborers are protected, and the occurrence of occupational diseases is avoided.

[0035] Furthermore, the simulation degree of the hair bundle product is improved by the dragging step.

[0036] Furthermore, the method provided by the present invention can use raw hair bundles to cut multiple manufacturing units in sequence, thereby reducing raw material loss and improving manufacturing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
