Description

Technical Field

[0001] The invention belongs to the technical field of embroidery technology, and in particular relates to a three-dimensional embroidery technology. Background Art

[0002] Beaded tube embroidery is a special embroidery craft that uses connected beads to fix decorative materials such as tube beads on the fabric through an embroidery machine or specific embroidery technology to form a unique three-dimensional embroidery pattern. When using special beaded tube embroidery equipment or machine beaded tube embroidery machinery, it is necessary to nail decorative materials such as tube beads on various clothing fabrics according to the embroidery pattern made by computer. This craft combines traditional embroidery with modern technology, making embroidery works more colorful. Beaded tube embroidery is famous for its unique three-dimensional sense, glossiness and decorative effect.

[0003] In order to increase the diversity of patterns in embroidery works, it is generally necessary to embroider with a combination of bead tubes of various colors or shapes. Therefore, in the prior art, a mixed embroidery fabric production process disclosed in Chinese patent CN113106646B has a technical scheme that includes the following steps: step S1, laser embroidering on the surface of the fabric to form a flower pattern; step S2, straightening and clamping the fabric on the embroidery table; step S3, moving the stretched fabric, embroidering the fabric through the embroidery mechanism, and mixing the mixed fabric. Embroidery beads are embroidered on the surface of the fabric to form a flower pattern; in step S3, the mixed embroidery beads include a main material and a plurality of auxiliary materials, which are fed through a mixed feeding mechanism; the mixed feeding mechanism includes a material changing box, a material changing disk is rotatably connected to the material changing box, and the material changing disk includes a plurality of material changing cylinders. When the material changing disk rotates, each material changing cylinder switches between a discharge pipe and a feed pipe. During the embroidery process, the fabrics can be mixed and processed with more different flower patterns, and laser embroidery processing technology is combined with a variety of embroidery processes.

[0004] However, the internal space of the material changing tray of the prior art is limited, so that it can only be used for mixed processing of beads with similar size parameters. When the size of the bead tube is larger than the size of the material changing tray, the material changing tray cannot be used for conveying the bead tube. Based on this, a three-dimensional embroidery process is proposed. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, the present invention provides a three-dimensional embroidery process.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A three-dimensional embroidery process comprises the following steps: S1: installing embroidery cloth; S2: pushing the bead tubes on the bead tube chain into the positioning tube clamps of the positioning material roller in sequence; S3: the positioning material roller rotates the bead tube to the bottom of the sewing machine needle, and makes the thread hole of the bead tube coincide with the moving direction of the sewing machine needle; S4: the bead tubes on the positioning material roller are sewn onto the embroidery cloth in sequence through the sewing machine needle; S5: a plurality of groups of positioning material rollers rotate in sequence to feed materials;

[0008] In S5, a sewing area is formed between the sewing machine needle and the embroidery cloth, and the rim surfaces of the plurality of positioning material rollers are arranged in a circular array based on the sewing area. The positioning tube clamps of the plurality of positioning material rollers respectively clamp a variety of bead tubes, and after the positioning tube clamps of the plurality of positioning material rollers rotate alternately to the sewing area, the sewing machine needle passes through the thread holes of the bead tubes and is sewn onto the embroidery cloth.

[0009] Furthermore, a plurality of the positioning tube clamps are equidistantly arranged on the rim surface of the positioning material roller, and the positioning tube clamps include a positioning base, a slide plate and a tension spring, the tension spring is arranged at the bottom of the positioning base, the slide plate is slidably arranged on the positioning base and abuts against the tension spring, and the slide plate slides on the positioning base to clamp bead tubes of different lengths.

[0010] Furthermore, it also includes a conveying roller, and a conveying roller is correspondingly arranged on one side of the rim surface of each positioning roller, and the conveying roller is used to take out the bead tubes from the bead tube chain in sequence and transfer them to the positioning tube clamp of the positioning roller.

[0011] Furthermore, a plurality of conveying tube clamps are equidistantly arranged on the rim surface of the conveying roller, and the conveying tube clamps include a conveying base and a seesaw, and the conveying base and the seesaw are used to clamp the bead tube.

[0012] Furthermore, the seesaw is rotatably connected to the conveying base, and a torsion spring is arranged between the seesaw and the conveying base. When the force on the side where the seesaw abuts against the bead tube increases, the seesaw is tilted up, and when the force decreases, the seesaw is reset due to the elastic force of the torsion spring.

[0013] Furthermore, the seesaw can be slidably disposed on the conveying base to clamp bead tubes of different lengths.

[0014] Furthermore, the positioning roller and the conveying roller are coaxially connected with a first driven gear and a second driven gear respectively, and the first driven gear and the second driven gear are both meshed with a driving gear, and the rotation of the driving gear is used to drive the positioning roller and the conveying roller to rotate synchronously in opposite directions at the docking point.

[0015] Furthermore, the length of the abutting surface of the slide plate of the positioning material roller is greater than the length of the abutting surface of the positioning base.

[0016] Furthermore, through grooves are provided on the abutting surfaces between the positioning base and the slide plate and on the abutting surfaces between the conveying base and the seesaw.

[0017] Furthermore, a blade is provided on the through slot of the seesaw for cutting the bead tube chain.

[0018] The beneficial effects of the present invention are:

[0019] (1) By arranging several groups of positioning material rollers around the sewing area, and clamping the bead tube by the positioning tube clamps on the positioning material rollers, only one group of positioning tube clamps on the positioning material rollers can be on the sewing area at the same time, and the corresponding positioning material rollers can be driven to rotate according to the bead tube required for the corresponding position of the pattern to be sewn through the sewing machine program. When the positioning material rollers rotate and the positioning tube clamps clamp the bead tube in the sewing area, the sewing machine needle moves downward and passes through the thread hole of the bead tube, the positioning material rollers rotate synchronously and separate the bead tube from the positioning tube clamp, and then the sewing machine needle sews the bead tube on the embroidery cloth. When bead tubes of different lengths are required, the positioning material rollers with bead tubes of different lengths respectively clamped rotate accordingly and provide bead tubes of corresponding lengths, so that the application scenarios of the equipment are wider and the sewing efficiency is higher;

[0020] (2) When the positioning tube clamp and the conveying tube clamp are at the closest point, one end of the bead tube on the conveying tube clamp abuts against the inner side of the slide plate, causing the slide plate to move. During the movement of the slide plate, the inner side of the vertical section of the seesaw is simultaneously subjected to abutment force. Under the action of the abutment force, the seesaw rotates and the vertical section tilts up, pushing the bead tube in the conveying tube clamp into the positioning tube clamp. After the slide plate loses the abutment force, it will gradually return to its original position and fix the bead tube in the positioning tube clamp.

[0021] (3) A driving motor is arranged on the driving gear. When the two driving gears are respectively meshed with the first driven gear and the second driven gear, when the driving gear rotates, the first driven gear and the second driven gear rotate in the same direction, and the diameters of the first driven gear and the second driven gear need to be the same, the diameters of the conveying roller and the positioning roller need to be the same, and the number of conveying tube clamps on the conveying roller and the number of positioning tube clamps on the positioning roller need to be the same. Under the driving action of the driving gear, the two gears can dock at the nearest point every time and complete the transfer of the bead tubes. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] like Figure 1-5 As shown, a three-dimensional embroidery process of the present invention comprises the following steps: S1: installing embroidery cloth; S2: pushing the bead tubes 4 on the bead tube chain into the positioning tube clamps of the positioning material roller 1 in sequence; S3: the positioning material roller 1 rotates the bead tubes 4 to below the sewing machine needle, and makes the thread holes of the bead tubes 4 coincide with the moving direction of the sewing machine needle; S4: the bead tubes 4 on the positioning material roller 1 are sewn onto the embroidery cloth in sequence through the sewing machine needle; S5: a plurality of groups of positioning material rollers 1 rotate in sequence to feed materials;

[0031] In S5, a sewing area 11 is formed between the sewing machine needle and the embroidery cloth, and the rim surfaces of the plurality of positioning material rollers 1 are arranged in a ring array based on the sewing area 11. The positioning tube clamps of the plurality of positioning material rollers 1 respectively clamp various bead tubes 4. The positioning tube clamps of the plurality of positioning material rollers 1 rotate alternately to the sewing area 11, and then the sewing machine needle passes through the thread holes of the bead tubes 4 and is sewn onto the embroidery cloth.

[0032] In order to increase the beauty and three-dimensional sense of the pattern during the embroidery process, bead tubes 4 or bead pieces are sewn on the embroidery cloth. The bead tubes 4 and bead pieces can present different colors and shapes. Bead tubes 4 or bead pieces of different colors and shapes are sewn on the embroidery cloth in sequence according to the position of the pattern to form a three-dimensional pattern. However, when using the bead tubes 4, since the pattern of the embroidery cloth requires bead tubes 4 of different colors and lengths, the prior art can only provide bead tubes 4 within a certain length range, which cannot meet the need for bead tubes 4 of various lengths to be used together;

[0033] Therefore, in order to improve the ability of the equipment to adapt to bead tubes 4 of different lengths during the embroidery process, a plurality of groups of positioning material rollers 1 are arranged around the sewing area 11. In order to avoid interference between the plurality of positioning material rollers 1, the number of positioning material rollers 1 should not be too large, and generally four groups are provided. The bead tubes 4 are clamped by the positioning tube clamps on the positioning material rollers 1. At the same time, only one group of positioning tube clamps on the positioning material rollers 1 can be on the sewing area 11. The corresponding positioning material rollers 1 can be driven to rotate according to the bead tubes 4 required for the corresponding positions of the pattern to be sewn through the sewing machine program. When the positioning material roller 1 rotates and the positioning tube clamp clamps the bead tube 4 in the sewing area 11, the sewing machine needle moves downward and passes through the thread hole of the bead tube 4, the positioning material roller 1 rotates synchronously and separates the bead tube 4 from the positioning tube clamp, and then the sewing machine needle sews the bead tube 4 onto the embroidery cloth. When bead tubes 4 of different lengths are needed, the positioning material rollers 1 with bead tubes 4 of different lengths respectively rotate accordingly and provide bead tubes 4 of corresponding lengths. Multiple positioning material rollers 1 can provide bead tubes 4 of various lengths when sewing three-dimensional embroidery, thereby expanding the application scenarios of the equipment and increasing the sewing efficiency.

[0034] In order to enable the positioning tube clamp to clamp bead tubes 4 of different lengths, in one embodiment, a plurality of positioning tube clamps are equidistantly arranged around the rim surface of the positioning material roller 1, and the positioning tube clamp comprises a positioning base 3, a positioning slide plate 2 and a tension spring, the tension spring is arranged at the bottom of the positioning base 3, the slide plate 2 is slidably arranged on the positioning base 3 and abuts against the tension spring, and the slide plate 2 slides on the positioning base 3 to clamp bead tubes 4 of different lengths and can clamp bead tubes 4 of different widths;

[0035] One end of the positioning base 3 is bent outward to extend a baffle, and a slide groove is provided at the bottom of the positioning base 3, so that the tension spring can be set in the slide groove, and the positioning slide plate 2 can also be slidably set in the slide groove. In the initial state, the positioning slide plate 2 is at a small distance from the baffle of the positioning base 3 under the action of the tension spring, and when clamping bead tubes 4 of different lengths, the tension of the tension spring on the positioning slide plate 2 can enable the positioning slide plate 2 and the baffle to clamp the bead tube 4, and the clamped bead tube 4 is rotated to the sewing area 11. After the bead tube 4 is passed through the sewing machine needle and separated from the positioning tube clamp, the slide plate 2 is reset under the action of the tension spring.

[0036] Since the bead tubes 4 are generally inserted into the bead tube chain, which is generally a sewing thread, and the positioning tube clamp needs to pull the slide plate 2 and move the slide plate 2 to clamp the bead tube 4, in order to place the bead tubes 4 on a long string of bead tube chains one by one on the positioning tube clamp, in one embodiment, a conveying roller 5 is further included, and a conveying roller 5 is correspondingly arranged on one side of the rim surface of each positioning material roller 1, and the conveying roller 5 is used to take out the bead tubes 4 from the bead tube chain in sequence and transfer them to the positioning tube clamp of the positioning material roller 1;

[0037] First, the bead tube chain is half-wound on the rim surface of the conveying roller 5, and then the conveying roller 5 and the positioning roller 1 have different rotation directions, and at the closest point between the positioning roller 1 and the conveying roller 5, the bead tube 4 is pushed into the positioning tube clamp of the positioning roller 1 through the rim surface of the conveying roller 5; specifically, a plurality of conveying tube clamps are equidistantly arranged around the rim surface of the conveying roller 5, and the conveying tube clamp includes a conveying base 6 and a seesaw 7, and the conveying base 6 and the seesaw 7 are used to clamp the bead tube 4;

[0038] The structure of the conveying base 6 is similar to that of the positioning base 3. A baffle plate is also provided at one end thereof and a slide groove is provided at the bottom thereof. The bottom of the seesaw 7 is slidably provided in the slide groove. By adjusting the position of the seesaw 7 in the slide groove, it can be used to clamp bead tubes 4 of different sizes. The distance between every two conveying tube clamps is the same as the distance between every two bead tubes 4 on the bead tube chain. When the conveying roller 5 rotates, each bead tube 4 on the bead tube chain can be correspondingly clamped on the conveying tube clamp. In order to prevent the adjusted seesaw 7 from loosening when clamping the bead tube 4, causing the bead tube 4 to fall off, the cooperation between the seesaw 7 and the slide groove has a large resistance, and can also be adjusted and fixed by screws and other parts.

[0039] At the same time, after the conveying tube clamp on the conveying roller 5 rotates to the closest point to the positioning tube clamp on the positioning roller 1, the bead tube 4 on the conveying tube clamp abuts against the inner side of the slide plate 2. The slide plate 2 slides after being subjected to force, causing the bead tube 4 to fall just between the slide plate 2 and the baffle of the positioning base 3, and then the slide plate 2 is reset under the tension of the tension spring and clamps the bead tube 4.

[0040] When the sewing machine needle sews the bead tube 4 on the embroidery cloth, the sewing area 11 is generally on a plane, so the height position of the positioning material roller 1 is also correspondingly low, and the bead tube 4 is connected in series on the bead tube chain. When the bead tube 4 is clamped on the positioning tube clamp, the bead tube chain needs to form a certain tension force. Therefore, the bead tube 4 on the bead tube chain needs to be clamped on the conveying tube clamp of the conveying material roller 5 in turn and then transferred.

[0041] When the bead tube 4 is moved to the positioning tube clamp by the conveying tube clamp, there is a probability that the bead tube 4 does not fall into the positioning tube clamp. In this case, the positioning material roller 1 and the conveying material roller 5 may be stuck. In order to avoid this problem, in one embodiment, the seesaw 7 is rotatably connected to the conveying base 6, and a torsion spring is arranged between the seesaw 7 and the conveying base 6. When the force on the side of the seesaw 7 abutting against the bead tube 4 increases, the seesaw 7 is tilted up, and when the force decreases, the seesaw 7 is reset with the elastic force of the torsion spring.

[0042] The bottom of the seesaw 7 can not only slide in the slide groove, but also rotate, and a torsion spring is arranged on the rotating shaft of the seesaw 7, so that the two force-bearing ends of the torsion spring respectively abut against the seesaw 7 and the slide groove, so that the seesaw 7 can clamp the bead tube 4 in the initial state, and when subjected to the abutting force from the inside to the outside, the seesaw 7 will rotate outward, and the seesaw 7 is in a right-angle shape, including a vertical section opposite to the baffle and a horizontal section vertically connected to the vertical section. When the vertical section is subjected to force and rotates, the horizontal section also rotates and tilts up. When the horizontal section of the seesaw 7 tilts up, it can push the bead tube 4 to move to the side of the positioning tube clamp;

[0043] Specifically, when the positioning tube clamp and the conveying tube clamp are at the closest point, one end of the bead tube 4 on the conveying tube clamp abuts against the inner side surface of the slide plate 2, causing the slide plate 2 to move. During the movement of the slide plate 2, the inner side surface of the vertical section of the seesaw 7 is simultaneously subjected to an abutting force. Under the action of the abutting force, the seesaw 7 rotates and causes the vertical section to tilt, pushing the bead tube 4 in the conveying tube clamp into the positioning tube clamp. After losing the abutting force, the slide plate 2 will gradually reset and clamp the bead tube 4 in the positioning tube clamp.

[0044] When the bead tube 4 on the conveying tube clamp is moved to the positioning tube clamp, the positioning tube clamp and the conveying tube clamp need to be at the closest point and can be perfectly opposite each time. In order to achieve this effect, the positioning material roller 1 and the conveying material roller 5 need to rotate synchronously. Therefore, in one embodiment, the positioning material roller 1 and the conveying material roller 5 are coaxially connected with a first driven gear 8 and a second driven gear 9, respectively. The first driven gear 8 and the second driven gear 9 are meshed with a driving gear 10. The driving gear 10 rotates to drive the positioning material roller 1 and the conveying material roller 5 to rotate synchronously in the opposite direction at the docking point.

[0045] The driving gear 10 is provided with a driving motor. When the two driving gears 10 are meshed with the first driven gear 8 and the second driven gear 9, when the driving gear 10 rotates, the first driven gear 8 and the second driven gear 9 rotate in the same direction, so that the positioning roller 1 and the conveying roller 5 both rotate counterclockwise, so that the conveying roller 5 rotates downward and the positioning roller 1 rotates upward at the docking point. In addition, the diameters of the first driven gear 8 and the second driven gear 9 need to be the same, the diameters of the conveying roller 5 and the positioning roller 1 need to be the same, and the number of conveying tube clamps on the conveying roller 5 is the same as the number of positioning tube clamps on the positioning roller 1, so that the conveying roller 5 can dock at the nearest point every time under the driving action of the driving gear 10 and complete the transfer action of the bead tube 4. Or when the diameters of the first driven gear 8 and the second driven gear 9 are different, the diameters of the two driving gears 10 need to be adjusted accordingly, and the number of tube clamps on the conveying roller 5 and the positioning roller 1 also need to be adjusted accordingly.

[0046] In order to enable the positioning tube clamp to receive the bead tube 4 on the conveying tube clamp and at the same time the positioning tube clamp and the conveying tube clamp will not interfere with each other when rotating, in one embodiment, the abutment surface length of the slide plate 2 of the positioning material roller 1 is greater than the abutment surface length of the positioning base 3. As shown in the figure, when the positioning tube clamp and the conveying tube clamp are at the closest point, the slide plate 2 is at the bottom, so the length of the petals is longer to receive the protruding bead tube 4, and due to the rotation angle, the slide plate 2 will not interfere with the conveying tube clamp. In order to make the positioning tube clamp and the conveying tube clamp form a certain angle when docking, on the one hand, to make the bead tube 4 fall into the positioning tube clamp after tilting under the action of gravity, on the other hand, to make the positioning tube clamp and the conveying tube clamp staggered, it is also necessary to make the conveying material roller 5 higher than the positioning material roller 1.

[0047] When the positioning butler clamps the bead tube 4 and rotates the bead tube 4 to the sewing area 11, the sewing machine needle needs to pass through the thread hole of the bead tube 4. Therefore, it is necessary to provide through grooves on the abutting surfaces of the positioning base 3 and the slide plate 2 as well as the abutting surfaces of the conveying base 6 and the seesaw 7.

[0048] In one embodiment, since the bead tubes 4 are all connected in series on the bead tube chain, when the bead tubes 4 are transferred from the conveying tube clamp to the positioning tube clamp, the bead tube chain needs to be disconnected to prevent the bead tubes 4 from being sewn into the embroidery cloth by the sewing machine needle. Therefore, a blade is provided on the through groove of the seesaw 7 for cutting the bead tube chain; the seesaw 7 is at the rear end of the rotation direction of the conveying roller 5. Therefore, when the bead tube 4 is clamped and rotated, the bead tube chain at the rear end of the bead tube 4 resists the blade on the through groove of the seesaw 7 and the bead tube chain is cut off by the blade.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
