Description

Technical Field

[0001] This invention belongs to the field of textile technology, and specifically relates to an improved hand brocade loom and its weaving method. Background Technology

[0002] Hand-woven brocade is an exquisite and beautiful silk fabric. It is made by using dyed warp and weft threads and employing techniques such as jacquard weaving to create patterns. The craftsmanship of hand-woven brocade is complex and time-consuming, hence the saying "an inch of brocade is worth an inch of gold," reflecting its preciousness.

[0003] In modern society, although modern and intelligent textile technology has developed unprecedentedly, continuing to develop hand-woven brocade still has many practical significances, mainly reflected in the following aspects:

[0004] Inheriting and protecting intangible cultural heritage: Hand-woven brocade is an important representative of intangible cultural heritage. It not only inherits weaving techniques but also contains rich historical and cultural connotations. By developing hand-woven brocade, we can better inherit and protect this intangible cultural heritage, allowing more people to understand and appreciate its historical origins and cultural significance.

[0005] Enhancing aesthetic literacy and art appreciation: Hand-woven brocade possesses unique artistic charm and aesthetic value. By appreciating and learning about hand-woven brocade, one can improve their aesthetic literacy and art appreciation abilities. At the same time, hand-woven brocade can also serve as a decorative item and work of art, enriching people's living spaces and cultural understanding.

[0006] Promoting Innovation and Sustainable Development: In modern society, innovation and sustainable development have become important characteristics of our time. Developing hand-woven brocade can drive innovation and sustainable development in related industries. For example, it can promote environmentally friendly and sustainable brocade weaving techniques by researching and developing new brocade materials and technologies.

[0007] Of course, the brocade loom plays an extremely important role in the field of hand textiles. The brocade loom helps weavers weave yarns more precisely to create unique textile works. For those who love handicrafts, the brocade loom is a powerful tool for realizing their creative ideas.

[0008] However, traditional hand-woven brocade production faces numerous problems and challenges due to limitations in technology and tools. Firstly, hand-woven brocade is inefficient, requiring extensive manual labor or multiple people working together, leading to increased production costs. Secondly, traditional hand-woven brocade machines cannot achieve high-precision weaving of complex patterns, affecting product quality and aesthetics. Furthermore, traditional hand-woven brocade machines are complex to operate and difficult to maintain, undoubtedly increasing production costs and time. Many other hand-woven brocade machines also suffer from limited operability, particularly their large size, which is not conducive to skilled workers and imposes high requirements, making widespread adoption in the contemporary brocade industry difficult.

[0009] Therefore, to address these issues and improve the production efficiency and product quality of hand-woven brocade, we have proposed a new type of hand-woven brocade machine. This new technology aims to improve upon traditional brocade machines by introducing innovative design concepts, such as modular design. Through a special structural design, the overall equipment is miniaturized, overcoming the shortcomings of traditional hand-woven brocade machines and effectively enhancing the efficiency and quality of hand-woven brocade production. Summary of the Invention

[0010] To address the aforementioned problems, this invention proposes an improved hand-woven brocade machine and its weaving method, which can further miniaturize the traditional brocade machine, reduce its footprint, improve production efficiency, and simplify the operation process, thus facilitating the further promotion of hand-woven brocade.

[0011] The technical solution adopted in this invention is as follows:

[0012] An improved hand-woven brocade machine includes a frame and a heddle selection mechanism. The frame includes a front frame, a rear frame, and a heddle support frame located between the front and rear frames. The rear frame is equipped with a warp feed shaft, and the front frame is equipped with a winding shaft. The heddle support frame includes two sets of heddle frames. The heddle selection mechanism is installed on the upper end of the heddle support frame and includes a translation component, a vertical translation component, and a lifting component. The translation component includes two longitudinally arranged horizontal translation rods, which are fixedly connected by at least one translation connecting rod. A translation rack is provided at the lower part of the translation rods. A heddle support frame is provided at the front and rear ends of the heddle support frame. It is equipped with a driving gear and a driven gear that mesh with the translation rack; the vertical movement assembly includes a selection crossbar, which is placed horizontally and vertically on two translation longitudinal bars. During the longitudinal movement, the translation longitudinal bars can pull the selection crossbar to move along with it. Vertical hook lifting devices are provided at both ends of the selection crossbar to hook and lift the lifting bar from both ends; the lifting assembly includes a transmission mechanism and two lifting frames. The two lifting frames are respectively installed on the upper part of the two heddle frames and are respectively located on the lower side of both ends of the selection crossbar. The lower end of the lifting frame is connected to the transmission mechanism, which can move up and down along the heddle frame under the drive of the transmission mechanism, and drive the selection crossbar to move up and down.

[0013] The present invention discloses an improved hand-woven brocade machine, wherein each of the two sets of heddle frames includes a front heddle support rod and a rear heddle support rod, and a drive gear shaft is installed between the tops of the two front heddle support rods, and two drive gears that can mesh with the translation rack are provided on the drive gear shaft.

[0014] The present invention discloses an improved hand-woven brocade machine, wherein the drive gear shaft includes a shaft body and shaft lugs at both ends of the shaft body that are coaxial with the shaft body, and a roller hole extending outward from either end of the shaft lug through the same side, and a rotating handle is provided perpendicular to the drive gear shaft at the end of the shaft lug on that side.

[0015] The improved hand-woven brocade machine of the present invention has a detachable driven gear shaft arranged laterally at the upper end of the two heddle supports corresponding to the drive gear shaft. Both ends of the driven gear shaft are provided with driven gears that correspond to the drive gear and can rotate freely.

[0016] The improved hand-woven brocade machine of the present invention includes a vertical shifting assembly comprising two heddle-selecting vertical rods and two heddle-selecting tongues. The two heddle-selecting vertical rods are respectively fixed vertically downward at both ends of the heddle-selecting horizontal rod, and the two heddle-selecting tongues are respectively fixed inward at the inner sides of the two heddle-selecting vertical rods. The distance between the ends of the two heddle-selecting tongues is less than the length of the hanging heddle rod, but greater than the distance between the outer sides of the two sets of heddle frames. When the heddle-selecting horizontal rod contacts the shifting vertical rod, the heddle-selecting tongues are entirely below the hanging heddle rod.

[0017] The present invention discloses an improved hand-woven brocade machine, wherein two vertical guide rods are vertically arranged in the middle of the translational longitudinal rod, and two vertical guide holes are provided on the selection crossbar corresponding to the two vertical guide rods. The selection crossbar is sleeved on the vertical guide rod through the vertical guide holes and can move freely up and down along the vertical guide rod.

[0018] The present invention discloses an improved hand-woven brocade machine, wherein the transmission mechanism includes a heddle pedal shaft horizontally installed at the lower part of the heddle support frame, a forward-facing heddle pedal is provided at either end of the heddle pedal shaft, and a lifting link is provided at each of the two ends of the heddle pedal shaft facing backward, and the upper ends of the two lifting links are respectively hinged to the bottom of the two lifting frames.

[0019] The present invention discloses an improved hand-woven brocade machine, wherein each lifting link includes a lower lifting link and an upper lifting link that are hinged to each other, and the upper end of the upper lifting link is hinged to the bottom of the lifting frame.

[0020] The present invention discloses an improved hand-woven brocade machine, wherein the lifting frame has a square structure and consists of two lifting vertical rods, an upper lifting rod and a lower lifting rod, and the upper lifting rod and the lower lifting rod are hinged in the middle.

[0021] The present invention discloses an improved hand-woven brocade machine, wherein each of the two lifting vertical rods on the heddle top rod and heddle bottom rod is provided with two lifting vertical rod guide holes, so that the lifting vertical rods can pass through the heddle top rod and heddle bottom rod simultaneously; during installation, the lifting upper rod of the lifting frame is first disassembled, and then the two lifting vertical rods are simultaneously inserted into the lifting vertical rod guide holes on the heddle bottom rod and heddle top rod from below, and then the lifting upper rod is installed on the corresponding lifting vertical rod from the top.

[0022] The brocade weaving method using an improved hand brocade loom according to the present invention includes the following steps:

[0023] Installing the warp threads: The neatly arranged warp threads wound on the warp feed shaft pass through the heddle frames in sequence according to the design drawing. For each heddle frame, the warp threads that need to be patterned pass through the eye of the long eye heddle, and the warp threads that do not need to be patterned pass through the side of the long eye heddle. Then, they pass through the two heddles alternately in groups, and pass through the reed teeth in pairs, and are fixedly wound on the winding shaft. Rotate the warp feed shaft and winding shaft in the opposite direction to adjust the warp tension, and fix the warp threads after they are taut. Step on the heddle pedal and the heddle pedal in sequence to lift the heddles and the heddles to ensure that the shed opens. The shed opening mentioned here refers to the clear and unobstructed channel between the lifted warp threads and the unlifted warp threads when viewed from the side.

[0024] Weaving plain weave: Alternately step on the two heavy heddle pedals and alternately lift the two heavy heddles to make the warp threads rise alternately to form a shed. Once the shed opens, the shuttle is inserted through the weft thread once, and the heavy heddle pedals are released to close the shed. The warp threads return to horizontal. Move the reed seat and use the reed to press the weft threads tightly. Repeat this process to weave a continuous plain weave.

[0025] Jacquard weaving: Stepping on the heddle pedal moves the lower lifting rod, upper lifting rod, and lifting frame upwards. Simultaneously, the lifting frame moves the heddle selection horizontal rod, vertical rod, and heddle selection tongue vertically upwards, lifting the corresponding heddle rod. This lifts the heddle frame attached to the heddle rod, causing the warp threads passing through the long eye of the heddle frame to be lifted to form a shed. Then, the shuttle is inserted through the weft thread once. The heddle pedal is released, the shed is closed, the warp threads return to horizontal, and the reed is moved to press the weft threads firmly. This completes one jacquard operation. In continuous jacquard weaving, after one jacquard operation is completed, a plain weave operation is followed, and this cycle is repeated to complete the jacquard process of the entire pattern.

[0026] The brocade weaving method using the improved hand brocade loom described in this invention also includes the step of adjusting the translation component to the initial position. That is, after the warp thread installation step is completed, the rotating handle is turned, and the driving gear meshes with the translation rack of the translation vertical rod, causing the scale mark of the translation vertical rod to align with the alignment mark engraved on the front support rod of the heddle on the frame. At this time, the position of the heddle tongue of the vertical translation component is exactly below the first hanging heddle rod at the front end of the heddle frame, thus achieving the purpose of equipment preparation.

[0027] The brocade weaving method using an improved hand brocade loom described in this invention further includes a step of selecting the target heddle frame in the jacquard weaving step. This involves rotating the handle to align the scale mark on the translation vertical bar corresponding to the target heddle rod with the alignment mark engraved on the front support rod of the heddle on the machine frame. In other words, the heddle frame connected to the target heddle rod is selected before proceeding with the subsequent jacquard weaving operation.

[0028] This invention, through the development of this improved hand-woven brocade machine and its weaving method, can achieve the following beneficial effects:

[0029] Improving production efficiency: Improved hand-woven brocade machines, through optimized design and technological upgrades, can increase the production efficiency of brocade weaving. This not only reduces production costs but also provides stronger support for the development of the brocade industry.

[0030] Simplified Operation: The improved hand-woven brocade machine simplifies the operation process, reducing the difficulty of use and making brocade weaving techniques easier to master. This will help increase the popularity and application of brocade weaving techniques, allowing more people to participate.

[0031] Promoting Innovative Design: Improved hand-woven brocade looms can be designed with greater emphasis on innovation and personalization, thereby meeting diverse consumer needs. Innovative design can lead to the development of more distinctive brocade products, driving the diversified development of the brocade industry.

[0032] Environmental sustainability: Improved hand-woven brocade machines can utilize environmentally friendly materials and sustainable technologies, reducing negative environmental impacts. This helps promote the sustainable development of the brocade industry and contributes to environmental protection.

[0033] This innovation will drive technological advancements in the hand-woven brocade manufacturing industry, improving production efficiency and product quality. At the same time, we hope that this innovation will inject new vitality into the inheritance and development of traditional handicrafts, promoting the sustainable development of the handicraft industry.

[0046] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments are now described. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention; that is, the described embodiments are only a part of the embodiments of the invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example 1

[0047] This embodiment relates to an improved hand-woven brocade machine, including a frame and a heddle-selecting mechanism. The frame includes a front frame 11, a rear frame 12, and a heddle support frame located between the front frame 11 and the rear frame 12. The rear frame 11 is equipped with a warp feed shaft 121, and the front frame 11 is equipped with a winding shaft 111. The front frame 11 and the rear frame 12 are fixedly connected by two parallel frame bottom longitudinal beams 13. The heddle support frame includes two sets of heddle frames 14, which are vertically and symmetrically installed on the two frame bottom longitudinal beams 13. A heddle frame receiving cavity is provided at the top of the heddle frame 14 for installing heddle frames 21. The bottom of the heddle frame receiving cavity is higher than the top of the front frame 11 and the rear frame 12. Both sets of heddle frames 14 include a front heddle support rod 141 and a rear heddle support rod 142, which are vertically installed on the longitudinal beam 13 at the bottom of the frame on the same side. The front heddle support rod 141 and the rear heddle support rod 142 are fixedly connected at the upper end by a heddle top rod 143.

[0048] The sorting mechanism is installed on the upper part of the heddle support frame. The sorting mechanism includes a heddle frame 21, a translation component, a vertical translation component, and a lifting component. The translation component includes two longitudinally arranged horizontal translation rods 22, which are fixedly connected by at least one translation connecting rod 221. Generally, two translation connecting rods 221 are sufficient to achieve a stable function and balance. Moreover, the two translation connecting rods 221 can be connected and fixed to the translation rods 22 from both ends to the middle 1 / 3 of the translation rod 22. This avoids the translation connecting rods 221 being too close to the ends of the translation rods 22, causing the translation rods 22 to move closer to the operator and affect the operator's work. A translation rack 222 is provided at the lower part of the translation longitudinal rod 22. A driving gear and a driven gear that mesh with the translation rack 222 are respectively provided at the front end and rear end of the heddle support frame. The vertical movement component includes a selection crossbar 23. The two ends of the selection crossbar 23 are respectively placed horizontally and vertically on the two translation longitudinal rods 22. Vertical hook lifting devices are provided at both ends of the selection crossbar 23 for hooking and lifting the heddle rod 211 from both ends. The lifting component includes a transmission mechanism and two lifting frames 24. The two lifting frames 24 are respectively installed on the upper part of the two heddle gantry frames 14 and are respectively located on the lower side of both ends of the selection crossbar 23. The lower end of the lifting frame 24 is connected to the transmission mechanism and can move up and down along the heddle gantry frame 14 under the drive of the transmission mechanism, and drive the selection crossbar 23 to move up and down.

[0049] Preferably, a bottom rod 144 is provided below the top rod 143 of the heddle frame. In this case, the heddle frame cavity is formed by the top rod 143, the bottom rod 144, the front support rod 141, and the rear support rod 142 of the heddle frame.

[0050] Preferably, to facilitate the installation of the heddles frame 21, a top rod step 1431 is provided on the lower inner side of the top rod 143, and a bottom rod step 1441 is provided on the upper inner side of the bottom rod 144. The thickness of the top rod step 1431 and the bottom rod step 1441 is greater than or equal to the thickness of the frame of the heddles frame 21. Rotating paddles 6 are provided on the inner sides of the top rod 143 and the bottom rod 144 for fixing the heddles frame 21.

[0051] Preferably, a detachable drive gear shaft 15 is laterally provided at the upper end of the two front support rods 141 of the heddles. A drive gear 151 and a rotating handle 152 are fixedly mounted on the drive gear shaft 15. Although one drive gear can achieve the desired effect, it is more preferable to provide drive gears 151 at both ends of the drive gear shaft 15 to achieve drive balance, reduce friction on the translational longitudinal rod 22, and improve the stability of the equipment by providing drive gears at both ends, preventing the translational components from skewing or jamming. Preferably, shaft holes 1411 are laterally provided at the upper ends of the two front support rods 141 for mounting the drive gear shaft 15. To reduce friction, the drive gear shaft 15 can be mounted in the aforementioned shaft holes 1411 using bearings.

[0052] Preferably, a detachable driven gear shaft 16 is laterally arranged at the upper end of the two heddle supports 142, corresponding to the drive gear shaft 15. Both ends of the driven gear shaft 16 are equipped with driven gears 161 that correspond to the drive gear 151 and can rotate freely. It is important to note that the installation methods of the driven gears 161 and 151 are different. After the drive gear 151 is installed on the drive gear shaft 15, it needs to be fixed and locked, and then the drive gear 151 can only rotate with the rotation of the drive gear shaft 15. However, after the driven gear 161 is installed on the driven gear shaft 16, the driven gear 161 can also rotate freely relative to the driven gear shaft 16. Specifically, the driven gear 161 can be installed on the driven gear shaft 16 via a bearing, or the outer ring of the bearing itself can be designed as a gear shape with the same tooth diameter and number of teeth as the drive gear 151, while the inner ring of the bearing is fixedly installed on the driven gear shaft 16. Both methods achieve the same effect.

[0053] Preferably, the shaft hole 1411 on at least one side is through-hole, and the driving gear shaft 15 includes a shaft body 153 and lugs 154 at both ends of the shaft body, which are coaxial with the shaft body 153. The lug 154 at one end extends outward from the through-hole 1411 on the same side, and a rotating handle 152 is provided perpendicularly to the driving gear shaft 15 at the end of the lug 154 on that side. The rotating handle 152 can be cylindrical or annular. Of course, the driven gear shaft 16 can be similar to the driving gear shaft 15, including a shaft body 162 and lugs 163 at both ends of the shaft body, which are coaxial with the shaft body 162.

[0054] Preferably, in order to make the structure of the heddle support frame more stable, a front crossbeam 145 and a corresponding rear crossbeam 145a are respectively provided below the aforementioned drive gear shaft 15 and driven gear shaft 16.

[0055] Preferably, a heavy-duty heddle shaft 17 is horizontally installed below the drive gear shaft 15, also below the front crossbeam 145, and between the two heddle front support rods 141, for hanging the heavy-duty heddles 3. Specifically, the two heavy-duty heddles 3 are hung on the heavy-duty heddle shaft 17 by two lifting ropes. The lower middle part of the two heavy-duty heddles 3 is connected to the front end of two heavy-duty heddle pedals 31 by two pedal ropes. The rear end of the two heavy-duty heddle pedals 31 are hinged to the frame base beam 114 of the front frame 11.

[0056] Furthermore, the front frame 11 includes two vertical front frame support rods 112, and the rear frame 12 includes two vertical rear frame support rods 122. Two to four warp roller holes 113 are respectively provided at the upper ends of the two front frame support rods 112, and two to four warp feed roller holes 123 are respectively provided at the upper ends of the two rear frame support rods 122. This arrangement allows for the adjustment of the height and relative position of the warp rollers 111 and 121 according to production tasks or the individual needs of operators, achieving optimal operating positions and production conditions. It also allows for the installation of double warp feed rollers and double warp rollers. With double warp feed rollers, the lower section is the actual warp feed roller, and the upper section is the drive shaft; with double warp rollers, the lower section is the actual warp roller, and the upper section is the drive shaft. This facilitates more convenient warp feeding operations and makes it easier to cut the woven fabric.

[0057] Preferably, at the lower part of the two flower-shaped brackets 14, a lifting limit rod 147 is provided between the frame bottom longitudinal beam 13 and the flower-shaped bracket bottom rod 144. A vertically penetrating longitudinal strip groove 1471 (or a longitudinal strip hole) is provided in the middle of the lifting limit rod 147. At this time, the groove opening of the longitudinal strip groove 1471 faces inward.

[0058] Preferably, the vertical moving assembly further includes two heddle-selecting vertical rods 231 and two heddle-selecting tongues 232. The two heddle-selecting vertical rods 231 are respectively fixed vertically downward at both ends of the heddle-selecting horizontal rod 23, and the two heddle-selecting tongues 232 are respectively fixed inward at the inner side of the lower end of the two heddle-selecting vertical rods 231. In this way, the heddle-selecting vertical rods 231 and the two heddle-selecting tongues 232 form the aforementioned hook-lifting device. When the horizontal moving assembly drives the vertical moving assembly to the position of the heddle-lifting rod 211, the lifting operation can be initiated, allowing the heddle-selecting horizontal rod 23 to move vertically upward with the heddle-selecting vertical rods 231 and the two heddle-selecting tongues 232, thereby lifting the heddle-lifting rod 211, that is, simultaneously lifting the heddle frame 5 attached to the heddle-lifting rod 211, to complete the corresponding jacquard operation steps.

[0059] Preferably, the distance between the two heddle tongues 232 is less than the length of the heddle rod 211 of the brocade loom, but greater than the outer distance between the two heddle base rods 144 of the brocade loom. In the case of the brocade loom of this technology, the distance between the two heddle tongues 232 is obviously between the length of the heddle rod 211 and the outer distance between the two sets of heddle frames 14, thus meeting the usage requirements. Of course, in this technology, the heddle rod 211 is greater than the outer distance between the two heddle base rods 144, and also greater than the outer distance between the two sets of heddle frames 14.

[0060] Preferably, two vertical guide rods 223 are vertically arranged at the middle of the translational longitudinal rod 22. The heddle crossbar 23 is provided with two vertical guide holes 233 corresponding to the two vertical guide rods 223. The heddle crossbar 23 is sleeved on the vertical guide rods 223 through the vertical guide holes 233 and can move freely up and down along the vertical guide rods 223. The vertical guide rods 223 not only serve as guides, but also drive the heddle crossbar 23 to move longitudinally when the translational longitudinal rod 22 moves longitudinally.

[0061] Furthermore, in this embodiment, the transmission mechanism of the lifting assembly includes a heddle pedal shaft 25 horizontally installed at the lower part of the heddle support frame. In this embodiment, the heddle pedal shaft 25 is specifically positioned on the two base longitudinal beams 13 below the heddle support frame. The heddle pedal shaft 25 is actually installed at the front between the two base longitudinal beams to facilitate operation by the operator sitting in front of the front frame 11. A forward-facing heddle pedal 251 is provided at either end of the heddle pedal shaft 25, and a lifting connecting rod is provided at each of the two rearward-facing ends of the heddle pedal shaft 25. The upper ends of the two lifting connecting rods are respectively hinged to the bottom of the two lifting frames 24.

[0062] Preferably, each lifting link includes a lower lifting link 252 and an upper lifting link 253 hinged to each other, with the upper end of the upper lifting link 253 hinged to the bottom of the lifting frame 24. More specifically, the lifting frame 24 has a square structure, consisting of two lifting vertical rods 241 on both sides, an upper lifting link 242, and a lower lifting link 243, with the top of the upper lifting link 253 hinged to the middle of the lower lifting link 243. The reason for dividing the lifting link into a hinged connection of the lower lifting link 252 and the upper lifting link 253 is that the lower lifting link 252 can link with the upper lifting link 253 to push the lifting frame 24 vertically up and down under a larger arc movement, making the miniaturization of the overall equipment possible. Through the applicant's continuous practice, this design can reduce the overall size to about 1 / 3 of the original size compared to the traditional brocade weaving machine, saving materials, reducing the footprint, and reducing the difficulty of operation.

[0063] Preferably, a lifting roller 244 is provided at each end of the lifting rod 243 of the lifting frame 24. This prevents the lifting frame 24 from directly contacting the front support rod 141 and the rear support rod 142 of the heddle frame 14 on the same side during vertical movement. The rolling of the rollers 244 also makes the vertical movement smoother and avoids jamming due to back-and-forth swinging. More preferably, the front support rod 141 and the rear support rod 142 of the heddle frame are respectively provided with roller grooves 148 corresponding to the lifting rollers 244. This can prevent the lifting frame 24 from being offset to the left or right during vertical movement and further reduce jamming due to left-and-right swinging.

[0064] The installation of the drive mechanism and the frame has been described above. The following section describes in detail how the lifting frame is connected and installed to the frame, which is mainly achieved through a special structure.

[0065] Each of the top and bottom heddle rods 143 and 144 has two lifting guide holes 149 corresponding to the two lifting vertical rods 241, allowing the lifting vertical rods 241 to pass through both the top and bottom heddle rods 143 and 144 simultaneously. During installation, the upper lifting rod 242 of the lifting frame 24 is first disassembled, and then the two lifting vertical rods 241 are simultaneously inserted into the lifting guide holes 149 on the bottom and top heddle rods 144 and 143 respectively from below. Finally, the upper lifting rod 242 is installed on the corresponding lifting vertical rod 241 from above. As the heddle pedal 251 is pressed down or released, the lifting frame 24 will move up or down accordingly, driven by the lower lifting link 252 and the upper lifting link 253. Naturally, the vertical moving components on the lifting frame 24 (including the heddle horizontal bar 23, the heddle vertical bar 231, the heddle tongue 232, and the heddle hanging bar 211) will also rise or fall, thus completing the jacquard operation.

[0066] Furthermore, a reed seat 4 is rotatably installed between the front frame 11 of the frame and the heddle support frame, and on the two bottom longitudinal beams 13 of the frame, with an organic reed 41 installed on the reed seat 4.

[0067] Furthermore, the hanging rods 211 of the heald frame 21 are numbered sequentially from front to back (taking a total of 24 hanging rods as an example, they are numbered as one, two, three... twenty-four). An alignment mark is provided on the inner side of the top of any of the heddle front support rods 141. Correspondingly, a scale is provided on the inner side of the translational longitudinal rod 22 on the same side, with the same number of scales as the heddle rods 211. The scale numbering rule is as follows: the two vertical guide holes 233 of the selection crossbar 23 of the vertical moving assembly are fitted onto the two vertical guide rods 223, so that the selection crossbar 23 is in direct contact with the two translational longitudinal rods 22. The rotating handle 152 is rotated so that the selection tongue 232 of the vertical moving assembly is aligned with the first heddle rod 211 numbered 1 from below. At this time, a scale mark is engraved at the corresponding position of the alignment mark aligned with the translational longitudinal rod 22, which is recorded as scale mark one. Then the rotating handle 152 is rotated so that the selection tongue 232 is aligned with the subsequent heddle rods 211 in sequence, and the corresponding scale mark two, scale mark three... is engraved on the translational longitudinal rod 22 in sequence until scale mark twenty-four is completed, so as to complete the marking work of all scale marks. In this way, a single operator can complete the operation, including selecting the target heddle frame 5, from the operating position at the front of the brocade machine, reducing the labor intensity of the workers. At this time, the height of the front support rod 141 of the heddle with the alignment mark is higher than or equal to the upper surface of the translation rod 22. The alignment mark can be marked on the inner side of the front support rod 141 above the translation rod 22, or the alignment mark pointer can be installed on the top of the front support rod 141 to align the scale.

[0068] The above constitutes a complete improved hand-woven brocade machine. Example 2

[0069] In the aforementioned Embodiment 1, the heddle frame 21 is installed on the heddle frame 14 from the inside. This embodiment will provide a structure in which the heddle frame 21 is installed from the outside. Specifically, see attached... Figure 3 As shown, a top rod step 1431a is provided on the lower outer side of the top rod 143, and a bottom rod step 1441a is provided on the upper outer side of the bottom rod 144. The thickness of the top rod step 1431a and the bottom rod step 1441a is greater than or equal to the thickness of the frame 21. Rotating tabs 6a are provided on the outer sides of the top rod 143 and the bottom rod 144 for fixing the frame 21. In this way, the frame 21 can be installed onto the heddle frame 14 from the outside, and of course, it can also be removed from the outside.

[0070] Although the only modification compared to Embodiment 1 is the method of installing and disassembling the heddle frame 21, it brings better technical results. After a pattern is woven, all the heddle frame groups 5 with the warp threads threaded are left with a section of warp thread at the front and back. Then, the vertical and horizontal movement mechanisms are disassembled sequentially from top to bottom. The heddle frame bars 21 on both sides are then removed from the outside of the heddle frame 14, while the ends of all the hanging heddle rods 211 are temporarily placed on the two heddle base rods 144. Then, all the hanging heddle rods 211 are gathered together and slowly turned from horizontal to vertical, which lifts the heddle frames 5 suspended on the hanging heddle rods 211 upwards to the machine frame as a whole. This preserves the hanging heddle rods 211 and the heddle frames 5 with the threads still in the threaded state as a group, avoiding the need to re-thread the threads when weaving the same pattern again. This is because threading the warp threads from the group of heddle frames 5 is a relatively labor-intensive and technically difficult process. This solves the problem of the limitation of one brocade per machine. Example 3

[0071] The method of weaving brocade using a modified hand loom includes the following steps:

[0072] Installing the warp threads: The neatly arranged warp threads wound on the warp feed shaft 121 pass through the heddle frames 5 in sequence according to the design. For each heddle frame 5, the warp threads requiring jacquard weaving pass through the eye of the long eye heddle, while those not requiring jacquard weaving pass through one side of the long eye heddle. Then, they alternately pass through two heddles 3 in groups, and in double groups, pass through the reed teeth of the reed 41, and are then fixedly wound onto the winding shaft 111. The warp feed shaft 121 and winding shaft 111 are rotated in the opposite direction to adjust the warp tension. After the warp threads are taut, they are fixed by inserting wooden wedges into grooves on the warp feed shaft and winding shaft, and then using a belt or fiber rope to pull them in the opposite direction. After fixing, the heddle pedal and the heddle pedal are stepped on sequentially to raise the heddles and ensure the shed opens. Here, "shed opening" refers to a clear and unobstructed channel between the raised and unraised warp threads when viewed from the side.

[0073] Weaving plain weave: Alternately step on the two heavy heddle pedals 31 and alternately lift the two heavy heddles 3 to raise the warp threads alternately to form a shed. Once the shed opens, the shuttle passes through the weft thread once. Then release the heavy heddle pedals 31, close the shed, and the warp threads return to horizontal. Move the reed seat 4 and use the reed 41 to press the weft thread tightly. Repeat this process to weave a continuous plain weave.

[0074] Jacquard weaving: Stepping on the heddle pedal 251 moves the lower lifting link 252, the upper lifting link 253, and the lifting frame 24 upwards. At the same time, the lifting frame 24 moves the selection heddle horizontal bar 23, the selection heddle vertical bar 231, and the selection heddle tongue 232 upwards vertically, lifting the corresponding heddle rod 211. This lifts the heddle frame 5 attached to the heddle rod 211, causing the warp threads passing through the long eye of the heddle frame 5 to be lifted to form a shed. Then, the shuttle is inserted through the weft thread once. The heddle pedal 251 is released, the shed is closed, the warp threads return to horizontal, and the reed seat 4 is moved to press the weft threads with the reed 41. This completes one jacquard operation. In the continuous jacquard weaving process, after one jacquard operation is completed, a plain weave operation is followed, and this cycle is repeated to complete the jacquard process of the entire pattern.

[0075] Furthermore, the process includes adjusting the translation component to its initial position. Specifically, after installing the warp threads, rotating the handle 152 engages the drive gear 151 with the translation rack 222 of the translation rod 22, aligning the scale mark on the translation rod 22 with the alignment mark on the front support rod 141 of the heald frame. At this point, the heald selection tongue 232 of the vertical translation component is positioned directly below the first heald rod 211 at the front end of the heald frame 21. This ensures the equipment is ready for operation.

[0076] Furthermore, the jacquard weaving process also includes the step of selecting the target heddle frame 5, that is, rotating the rotating handle 152 to align the scale mark on the translation vertical bar 22 corresponding to the target hanging heddle bar 211 with the alignment mark engraved on the front support bar 141 of the heddle on the machine frame, that is, selecting the heddle frame 5 connected to the target hanging heddle bar 211, and then proceeding with the subsequent jacquard weaving operation.

[0077] The functions of the machine described in this invention are not limited to the warp setting and weft shuttle mentioned in the embodiments. The machine of this invention can be applied to a variety of warp setting and weft weaving methods, including but not limited to lifting the warp with the heald frame, controlling one or more warp threads with the traction line, creating patterns with multi-colored warp groups, controlling the warp to create patterns with multi-colored weft threads, warp pattern cutting, and weft track changing, etc.

[0078] In general, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
