DETAILED DESCRIPTION

[0044] In view of this, the core of the present invention is to provide a method for preparing a three-dimensional knitted shoe body, which can shorten the shoe body manufacturing process, reduce the waste of manpower and material resources, and effectively improve the shoe body manufacturing efficiency.

[0045] Another core of the present invention is to provide a shoe body.

[0046] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figures 1 to 9 .

[0047] Please refer to Figure 1 , Figure 3 and Figure 4As the first embodiment of the present invention, a method for preparing a three-dimensional knitted shoe body disclosed in the embodiment of the present invention includes a shoe body knitting step and a shoe body closing step. The shoe body knitting step includes: knitting the first area 101 of the shoe body 100 on the first needle bed 500, and knitting the second area 102 of the shoe body 100 on the second needle bed 600, and knitting the first area 101 and the second area 102 from the needle starting position to the needle dropping position into an integrated structure, the first area 101 and the second area 102 both include a sole part and an upper part, wherein the first area 101 and the second area 102 are divided and formed along the width direction of the shoe body 100. The shoe body closing step includes: closing the needle dropping position of the first area 101 or the second area 102 to form a shoe body 100 with a three-dimensional structure.

[0048] When knitting the shoe body 100, the shoe body 100 needs to be divided into a first area 101 and a second area 102 for knitting, wherein the first area 101 and the second area 102 both include a sole part and an upper part. When knitting, the first area 101 needs to be knitted on the first needle bed 500, and the second area 102 needs to be knitted on the second needle bed 600. The first area 101 and the second area 102 are knitted into an integrated structure from the needle starting position to the needle dropping position. When the knitting is completed, the needle dropping position of the first area 101 or the second area 102 is closed, thereby completing the knitting of the three-dimensional structure of the shoe body 100.

[0049] Compared with the prior art, the three-dimensional knitted shoe preparation method disclosed in the embodiment of the present invention eliminates the steps of material arrangement, cutting, sewing, bonding and reinforcement, greatly shortens the shoe production process, reduces the waste of manpower and material resources, and effectively improves the shoe production efficiency.

[0050] Due to the structural limitations of the first needle machine 500 and the second needle machine 600, in order to increase the richness of the structure of the shoe body 100, a method combining partial knitting and continuous knitting may also be used.

[0051] Please refer to Figure 2 , Figure 5 and Figure 6As a second embodiment of the present invention, the method for preparing a three-dimensional knitted shoe body disclosed in the embodiment of the present invention further includes a composite sole knitting step, a composite heel knitting step and a connecting band knitting step before the shoe body knitting step, wherein the composite sole knitting step is to knit the first side of the composite sole 200 on the first needle bed 500, and to knit the second side of the composite sole 200 on the second needle bed 600; the composite heel knitting step is to knit the first side of the composite heel 300 on the first needle bed 500 after the knitting of the composite sole 200 is completed, and to knit the second side of the composite heel 300 on the second needle bed 600; the connecting band knitting step is to knit the first side of the connecting band 400 on the first needle bed 500 after the knitting of the composite heel 300 is completed, and to knit the second side of the connecting band 400 on the second needle bed 600.

[0052] It should be noted that the first side of the composite sole 200 and the second side of the composite sole 200 are formed along the width direction of the composite sole 200; the first side of the composite heel 300 and the second side of the composite heel 300 are formed along the width direction of the composite heel 300; the first side of the connecting band 400 and the second side of the connecting band 400 are formed along the width direction of the connecting band 400, wherein the connecting band 400 can be connected to the shoe body 100.

[0053] After the composite sole 200, the composite heel 300, the connecting strap 400 and the shoe body 100 are woven in sequence, the shoe body is connected. Figure 7 As shown, it is necessary to follow Figure 7 The middle arrow indicates that the shoe body 100 is rotated by a preset angle so that the shoe body 100 is placed on the composite sole 200 and fits and fixes with the composite heel 300. The shoe body prepared by the above preparation method can further improve the applicability of the sole and the heel.

[0054] It can be understood that the upper part disclosed in the embodiment of the present invention includes the heel 104, the upper body 105 and the toe 107, wherein in the shoe body knitting step, the needle starting position is preferably the heel 104, and the needle dropping position is preferably the toe 107.

[0055] That is to say, when starting to knit, the first area 101 and the second area 102 are connected, and until the needle is dropped, the first area 101 and the second area 102 are woven into a shoe body 100 with a three-dimensional integrated structure.

[0056] When the shoe body is specifically knitted, the knitting starts from the heel 104. During the forming process of the heel 104, the needles need to be gradually placed in the same direction on the first needle bed 500 and the second needle bed 600 at the same time to achieve transition knitting from the heel 104 to the sole part 103. After the knitting of the heel 104 is completed, the sole part 103 and the upper part can be knitted at the same time until the shoe body 100 is knitted.

[0057] In the daily shoe body 100, some shoes are provided with the tongue 106, while some shoes are not provided with the tongue 106. When the shoe body 100 is provided with the tongue 106, the tongue 106 needs to be knitted after the upper part is knitted. When knitting the tongue 106, it is also necessary to knit half of the tongue 106 on the first needle bed 500 and the second needle bed 600 respectively to complete the knitting of the tongue 106.

[0058] Of course, when the shoe body 100 needs to be provided with shoe holes 109, the shoe holes 109 also need to be knitted. When knitting the shoe holes 109, the knitting of the shoe holes 109 can be completed by transferring the loops and turning the needles.

[0059] It should be noted that when knitting the sole portion 103 , it is necessary to involve a process of narrowing or widening the stitches, wherein the number of widened stitches is determined by the size and shape of the sole portion 103 .

[0060] In the step of knitting the shoe body, both the first area 101 and the second area 102 are knitted in the form of rib structure.

[0061] It needs to be explained that the rib structure is the basic structure of double-sided weft knitted fabrics, which is composed of vertical rows of front coils and vertical rows of back coils arranged alternately in a certain combination.

[0062] The first area 101 and the second area 102 are connected by transferring the stitches of the first needle bed 500 and the second needle bed 600 to each other.

[0063] It should be explained that transferring loops means moving part of the loops on the first needle bed 500 to the second needle bed 600, or moving part of the loops on the second needle bed 600 to the first needle bed 500. The two needle beds exchange some loops with each other. When knitting continues, the loops on the first needle bed 500 and the second needle bed 600 will be intertwined.

[0064] In the shoe body weaving step, the sole portion 103 and the heel 104 are both woven in the form of pads to meet different design requirements.

[0065] In order to improve the wearing comfort of the human body, in the shoe body knitting step disclosed in the first embodiment of the present invention, when knitting the sole part 103, needles need to be placed at the arch position of the sole part 103 so that it can fit the arch part of the human body.

[0066] In order to ensure the strength of the shoe body 100 while improving the air permeability of the shoe body 100 , in the shoe body weaving step, holes are woven on the upper body 105 .

[0067] It should be explained that the division along the width direction of the shoe body 100 refers to the division along the direction from the toe 107 to the heel 103 of the shoe body 100 .

[0068] The embodiment of the present invention does not limit the specific size range of the first area 101 and the second area 102. As long as the use requirements of the present invention are met, they are within the protection scope of the present invention.

[0069] As a preferred embodiment, the first area 101 and the second area 102 are divided and formed along the central axis of the shoe body 100 .

[0070] The embodiment of the present invention does not specifically limit the number of the first needle beds 500 and the second needle beds 600. As long as the number meets the use requirements of the present invention, it is within the protection scope of the present invention.

[0071] Among them, the first needle bed 500 disclosed in the embodiment of the present invention can be provided in one, two, or more than two, and the second needle bed 600 can be provided in one, two, or more than two.

[0072] As a preferred embodiment, the first needle beds 500 disclosed in the embodiment of the present invention are preferably two, and the second needle beds 600 are preferably two. The first and second embodiments of the present invention both take four needle beds as an example to weave the shoe body 100, wherein the change in the lateral size of the shoe body is achieved by retracting and expanding the needles between the four needles, and the change in the longitudinal size is controlled by the number of knitting rows.

[0073] The weaving density and texture effect of different parts of the shoe body 100 can be changed by adjusting the tightening and scaling of some coils. Parts with higher strength requirements, such as the toe 107 and the heel 104, need to be tightened; in parts with higher breathability requirements, such as the upper body 105, the looseness of the coil can be changed by a larger pulling force. Of course, a knitted structure with higher tightness or looseness can also be directly selected for weaving.

[0074] In order to make the shoe opening 108 of the shoe body 100 form a shape that is high on both sides and low in the middle, when knitting, it is necessary to increase the needle when knitting the heel 104, reduce the needle when knitting the upper body 105, and increase the needle when knitting the tongue 106. Figure 3or Figure 6 The shoe opening 108 structure of the shoe body 100.

[0075] It should be noted that the composite sole 200, the composite heel 300 and the connecting belt 400 are preferably woven in a folded form.

[0076] Please refer to Figures 7 and 8 The composite sole 200 and the composite heel 300 are both composite double-sided structures. The surface layer of the composite heel 300 is woven with a first lining protrusion 201, and the surface layer of the composite heel 300 is woven with a second lining protrusion 301, so that the effects of wrapping and effective support can be achieved.

[0077] It should be explained that the first padding protrusion 201 and the second padding protrusion 301 are both a three-layer knitted structure, consisting of two surfaces and a padding yarn in the middle. The padding yarn forms an unclosed suspended arc in certain loops in the weft direction of the fabric according to a certain proportion, and is in the inner layer of the fabric in the form of floating yarn where the suspended arc is not formed.

[0078] In the second embodiment of the present invention, the lining yarn used in the shoe body 100 is of coarser specifications, so it shows a concave and convex effect, wherein the concave part is where the lining yarn forms a coil, and the convex part is where the lining yarn has floating lines in the inner layer of the shoe body 100.

[0079] The second embodiment of the present invention does not limit the specific length of the connecting belt 400. As long as the structure meets the use requirements of the present invention, it is within the protection scope of the present invention.

[0080] As a preferred embodiment, the length of the connecting belt 400 disclosed in the embodiment of the present invention is preferably 4 cm-6 cm.

[0081] Preferably, the surface layer of the composite sole 200 may be made of anti-odor and anti-bacterial yarn to fit the human foot and provide comfort.

[0082] The surface layer of the composite sole 200 is woven with hot-melt yarn, which can be heated and bonded to the shoe body 100 later.

[0083] In the second embodiment of the present invention, the sole portion 103 and the heel 104 of the shoe body 100 can be woven into a single-sided structure without padding, and those skilled in the art can make the selection according to actual needs.

[0084] The embodiment of the present invention further discloses a shoe body 100, which is made by the three-dimensional knitted shoe body preparation method disclosed in any one of the above embodiments.

[0085] Since the shoe body 100 is made by the three-dimensional knitted shoe body preparation method disclosed in the embodiment of the present invention, the shoe body 100 has the technical advantages of the three-dimensional knitted shoe body preparation method disclosed in the embodiment of the present invention, and the embodiment of the present invention will not elaborate on this one by one.

[0086] In the description of the present application, it should be noted that the terms “first” and “second” are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0087] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
