Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of warping machines and yarn feeding methods, and particularly relates to a warping machine and a method for feeding warp yarns using the warping machine. Background Technology
[0002] In the process of metal mesh weaving, the warp yarn spools need to be placed on the frame of the warping machine. After the warp yarns are wrapped around the rollers, they are passed through the threading holes of the yarn separator. Existing warping machines include a frame with a central frame. Multiple rows of support rods are fixed vertically on both sides of the central frame. Each row of support rods includes support rods spaced at a certain distance. Rollers are installed on the frame outside the support rods. A yarn separator is installed in front of the frame. A strip-shaped support plate running in the front-to-back direction is installed above each row of support rods. Positioning posts are installed at a certain distance on the strip-shaped support plate. A base plate with a column at the top and a bearing at the bottom is installed above each positioning post. The bearing is sleeved on the positioning post. The spools with warp yarns are placed on the columns, and the columns and base plate rotate to achieve the yarn feeding function. The aforementioned warping machines have the following drawbacks: First, because the diameters of warp yarn spools vary depending on the diameter of the yarn, a larger distance is required between adjacent positioning posts to accommodate larger diameter spools. For smaller diameter spools, the greater distance between the two spools extends the length of the warping machine and increases its material costs. Second, the length of the warp yarn on each spool is approximately 10,000 meters. After weaving the set mesh length, if the warp yarn diameter of the next mesh to be woven differs from the previous batch, all unused spools must be removed from the warping machine, transported to the warehouse, and then the new diameter warp yarn spools must be placed on the posts. First, when using warp threads of the same diameter again, the new warp thread must be wound around the corresponding roller and passed through the dividing hole of the corresponding dividing frame. Second, when using warp threads of the same diameter again, the new spool of thread must be removed, the old spool of thread of the same diameter must be reinstalled, and the warp thread must be wound around the corresponding roller and passed through the dividing hole of the corresponding dividing frame again. This is not only time-consuming and labor-intensive, but also wastes space. Third, the positioning post is fixed on the strip tray. Because the distance between the strip trays is relatively short, when the spool of thread is placed on the positioning post, the spool of thread needs to be tilted, and then the center hole of the spool of thread needs to be aligned with the positioning post. The positioning post is then inserted into the center hole of the spool of thread. Because the spool of thread is made of metal, it is heavy and inconvenient to pick up and put down. Summary of the Invention
[0003] The first technical problem to be solved by this invention is to provide a warping machine that is simple in structure, has a wide range of applications, can adjust the distance between the warp spools as needed, and does not require removing the original warp spools when weaving meshes with warp threads of different diameters, thus saving manpower, material resources and reducing space occupation.
[0004] To solve the above problems, the technical solution adopted by the warping machine of the present invention is as follows: It includes a frame with a central frame, multiple rows of support rods are fixedly arranged vertically on both sides of the central frame, each row of support rods includes support rods spaced at a certain distance, rollers are arranged on the frame outside the support rods, a wire separating frame is arranged in front of the frame, a strip-shaped support plate is arranged above each row of support rods in the front-back direction, a wire coil fixing seat is arranged above the strip-shaped support plate, the wire coil fixing seat includes a base, a first annular groove is provided on the upper surface of the base, and a center limit is provided at the center of the base. A positioning hole is provided above the base, and a top cover is provided above the top cover. A center rod is provided on the upper surface of the top cover, and a second annular groove corresponding to the first annular groove is provided on the lower surface of the top cover. A center limiting post is provided at the center of the lower surface of the top cover, and the center limiting post is inserted into the center limiting hole. A pressure bearing is provided between the first annular groove and the second annular groove. Limiting blocks are provided on both sides of the lower bottom surface of the base, and a slot is formed between the two limiting blocks. The width of the slot is slightly larger than the width of the strip tray, and the strip tray is locked in the slot.
[0005] Its additional technical features are:
[0006] The card slot is inverted "U" shaped;
[0007] A lower ejector hole communicating with the lower surface of the base is provided at the bottom of the first annular groove; an upper ejector hole communicating with the upper surface of the upper cover is provided at the top of the second annular groove.
[0008] Compared with the prior art, the warping machine provided by this invention has the following advantages: Firstly, it includes a frame with a central frame, and multiple rows of support rod groups are fixedly arranged vertically on both sides of the central frame. Each row of support rod groups includes support rods spaced at a certain distance. Rollers are arranged on the frame outside the support rods. A wire separating frame is arranged in front of the frame. A strip-shaped support plate is arranged above each row of support rod groups in the front-back direction. A wire spool fixing seat is arranged above the strip-shaped support plate. The wire spool fixing seat includes a base, a first annular groove is arranged on the upper surface of the base, and a central limiting hole is arranged in the center of the base. A top cover is provided, with a central rod on its upper surface. A second annular groove corresponding to the first annular groove is provided on the lower surface of the top cover. A central limiting post is provided at the center of the lower surface of the top cover, and the central limiting post is inserted into the central limiting hole. A pressure bearing is provided between the first and second annular grooves. Limiting blocks are provided on both sides of the lower bottom surface of the base, forming a groove between the two limiting blocks. The width of the groove is slightly larger than the width of the strip-shaped support plate, and the strip-shaped support plate is secured within the groove. Thus, when the wire coil is sleeved on the central rod, the wire coil and the top cover are connected by the pressure shaft. The base connects to the spool, and the spool rotates together with the top cover under the traction of the warp threads. In case of a malfunction or reaching the desired weaving length, the warp threads stop being pulled, and the spool and top cover quickly stop rotating under the resistance of the pressure bearing, preventing warp thread tangling caused by the spool's inability to stop rotating. The base can be moved forward or backward according to the spool diameter. When there are unused warp threads on the spool and different warp diameters need to be woven, the unused warp threads can be moved forward or backward, and then the required warp diameter spool can be placed on the center rod of the adjacent warping machine. The unused spool does not need to be removed, saving manpower and resources, reducing space occupation, and greatly improving production efficiency. Firstly, the winding mechanism is improved, and the yarn is always flush with the roller, resulting in good yarn feeding. Secondly, because the slot is an inverted "U" shape, it is easily engaged with the strip support plate, allowing the warping machine to move back and forth easily, but not laterally. This makes it more convenient to use when the warp yarn passes the roller in a lateral direction that is basically perpendicular to the direction of warp yarn movement. Thirdly, because a lower ejection through hole communicating with the lower surface of the base is provided at the bottom of the first annular groove, and an upper ejection through hole communicating with the upper surface of the upper cover is provided at the top of the second annular groove, it is very convenient to eject the pressure bearing from the first and second annular grooves when the pressure bearing fails, making it more convenient to use.
[0009] The second technical problem to be solved by the present invention is to provide a method for feeding warp threads using the above-mentioned warping machine.
[0010] To solve the above-mentioned technical problems, the technical solution adopted by the present invention for feeding warp threads using a warping machine is as follows:
[0011] For a method involving two warp threads of different diameters, the method includes the following steps:
[0012] The first step is to place the first type of warp yarn.
[0013] The first step is to conduct a tensile strength test.
[0014] The tensile strength of the first type of warp yarn to be placed is tested. The yarn spools that do not meet the tensile strength requirements are removed and used as weft yarns.
[0015] Step (2): Place the yarn roll
[0016] For the compliant spools, the first and second spools are placed on the center rods of the two foremost spool holders on the left and right sides, and the subsequent spools are placed on the next spool holder that is one spool holder apart, and so on, until all the warp threads of the first diameter are placed.
[0017] The second step is to place the second type of warp yarn.
[0018] The first step is to conduct a tensile strength test.
[0019] The tensile strength of the warp yarns of the second type of yarn diameter to be placed is tested. The yarn spools that do not meet the tensile strength requirements are removed and used as weft yarns.
[0020] Step (2): Place the yarn roll
[0021] For the compliant spools, the first and second spools are placed on the center rods of the two spool holders located at the front on the left and right sides, behind the spools of the first diameter. The spools that follow are placed on the next spool holder that is one spool holder apart, and so on, until all the warp threads of the second diameter are placed.
[0022] The third step is to use the first type of yarn diameter warp yarn guide.
[0023] The warp ends of the first type of yarn are drawn out from the yarn spool, passed around the corresponding roller, and then through the splitting hole of the corresponding splitting frame before being led out to the loom.
[0024] Step 4, the second type of wire diameter warp wire guide.
[0025] The warp end of the second type of wire diameter is drawn out from the spool, passes around the corresponding roller, passes through the wire splitting hole of the corresponding wire splitting frame, and is then fixed in front of the wire splitting frame by binding or other means.
[0026] Fifth step, adjust each wire reel fixing bracket.
[0027] Adjust the front and rear distances of each spool fixing seat as needed so that the center rod of the spool fixing seat containing the two spools of the first type of wire diameter and the roller corresponding to the spool are on the same vertical plane;
[0028] Step 6: Weave using warp threads of the first diameter.
[0029] Turn on the loom and pull the warp yarns forward through the warp yarn traction mechanism. The warp yarns of the first yarn diameter are unspinned from the spool and woven together with the weft yarns on the loom to form a mesh.
[0030] Step 7: Replace with warp yarns of the second diameter.
[0031] When the length of the warp yarn of the first yarn diameter reaches the required length, the warp yarn is cut off in front of the splitting hole of the splitting frame, and the front end of the warp yarn is fixed on the corresponding splitting frame. Then the end of the warp yarn of the second yarn diameter is untied from the corresponding splitting frame and stretched onto the loom.
[0032] Step 8: Adjust each wire reel holder.
[0033] Adjust the front and rear distances of each spool fixing seat as needed so that the center rod of the spool fixing seat containing the two spools of the first type of wire diameter and the roller corresponding to the spool are on the same vertical plane;
[0034] Step 9: Weave using warp threads of the second diameter.
[0035] Turn on the loom and pull the warp yarns forward through the warp yarn traction mechanism. The warp yarns of the second diameter are unspinned from the spool and woven together with the weft yarns on the loom to form a mesh.
[0036] Step 10: Determine whether to replace the warp with a second diameter yarn, depending on the needs.
[0037] Depending on the required length of the woven mesh, decide whether to change to a different warp wire diameter.
[0038] A method for conveying two warp threads of the same diameter includes the following steps:
[0039] The first step is to place the warp threads.
[0040] The first step is to conduct a tensile strength test.
[0041] The warp threads to be placed are subjected to tensile strength tests. The spools that do not meet the tensile strength requirements are removed and used as weft threads.
[0042] Step (2): Place the yarn roll
[0043] For compliant spools, the first and second spools are placed on the center rods of the two foremost spool holders on the left and right sides, and the subsequent spools are placed on the adjacent spool holders in sequence until all the warp threads are laid.
[0044] The second step is to introduce the first batch of warp threads.
[0045] Starting from the first spool holder at the front end of the warping machine, the ends of all odd-numbered spool holders are led out from the spool, pass around the corresponding roller, pass through the spool hole of the corresponding spool holder, and are led out to the loom.
[0046] The third step is to introduce the second batch of warp threads.
[0047] Starting from the second spool holder at the front of the warping machine, the ends of all even-numbered spool holders are led out from the spool, pass around the corresponding roller, pass through the spool hole of the corresponding spool holder, and are then secured in front of the spool holder by binding or other means.
[0048] Fourth step, adjust each wire reel fixing bracket.
[0049] Adjust the front and rear distances of each spool fixing seat as needed so that the center rod of the spool fixing seat where the two spools of the first batch of warp yarn are located and the roller corresponding to the spool are on the same vertical plane;
[0050] The fifth step is to weave with the first batch of warp threads.
[0051] Turn on the loom, and the warp yarns are pulled forward by the warp yarn traction mechanism of the loom. The first batch of warp yarns are unspinned from the yarn spool and woven into a mesh with the weft yarns on the loom.
[0052] Step 6: While replacing the second batch of warp yarns, replace the used first batch of warp yarn spools with new spools, and complete the first batch of warp yarn lead-in.
[0053] After the first batch of warp yarns is used, the ends of the second batch of warp yarns are untied from the corresponding yarn separators and stretched onto the loom. The ends of all odd-numbered yarn separators, starting from the first yarn separator at the front of the warping machine, are led out from the yarn separators, passed around the corresponding rollers, and then through the yarn separator holes of the corresponding yarn separators. They are then secured in front of the yarn separators by binding or other means.
[0054] Step 7: Adjust each wire reel holder.
[0055] Adjust the front and rear distances of each spool fixing seat as needed so that the center rod of the spool fixing seat where the two spools of the second batch of warp yarn are located and the roller corresponding to the spool are on the same vertical plane;
[0056] Step 8: Weave using warp threads of the second diameter.
[0057] Start the loom, and the warp yarns are pulled forward by the warp yarn traction mechanism of the loom. The second batch of warp yarns is unspinned from the yarn spool and woven into a mesh with the weft yarns on the loom.
[0058] Step 9: While replacing the first batch of warp yarns, replace the used second batch of warp yarn spools with new spools, and complete the second batch of warp yarn lead-in.
[0059] After the second batch of warp yarns is used, the ends of the first batch of warp yarns are untied from the corresponding yarn separators and stretched onto the loom. The ends of all even-numbered yarn separators, starting from the second yarn separator at the front of the warping machine, are led out from the yarn separators, passed around the corresponding rollers, passed through the yarn separator holes of the corresponding yarn separators, and then secured in front of the yarn separators by binding or other means.
[0060] Step 10: Start repeating from step 4 until all weaving tasks are completed.
[0061] The method for feeding warp threads using a warping machine provided by this invention has the following advantages compared with the prior art:
[0062] I. For warp threads of different diameters:
[0063] Advantage 1: Different warp yarns of different diameters can be spaced on the center rod of the yarn spool holder. The end of the warp yarn of the first diameter is led out from the yarn spool, around the corresponding roller, and through the splitting hole of the corresponding splitting frame before being led out to the loom. The end of the warp yarn of the second diameter is led out from the yarn spool, around the corresponding roller, and through the splitting hole of the corresponding splitting frame before being led out and fixed in front of the splitting frame by binding or other means. When changing warp yarns of different diameters, it is not necessary to remove the yarn spool from the warping machine, transport it and put it in the warehouse. Instead, the unused warp yarn ends are directly fixed on the corresponding splitting frame. When used again, they can be directly led out from the splitting frame, which not only saves manpower and resources, but also reduces space occupation.
[0064] Advantage 2: The spool holder can move back and forth along the strip support plate. The distance between each spool holder can be adjusted as needed, so that the center rod of the spool holder where the two spools of the second batch of warp yarn are located is on the same vertical plane as the roller corresponding to the spool. The spool is always flush with the roller, resulting in a good yarn feeding effect.
[0065] Advantage 3: Since the spool holder can move back and forth along the strip tray, there is no gap between each adjacent spool holder on the strip tray. In this way, more spool holders can be placed on the warping machine of the same length.
[0066] II. For warp threads of the same diameter:
[0067] Advantage 1: For smaller diameter spools, more spool holders can be placed on the strip tray. This allows for a total of twice the number of spool holders to be placed on the strip tray at once, or the spool holders can be placed only in the front half of the warping machine, halving the length of the warping machine. While feeding the spools in the front half of the warping machine, the spools in the back half can be placed and guided, greatly improving work efficiency. The same principle applies to larger diameter spools, making it more versatile. One warping machine can handle the warp feeding of spools with various diameters.
[0068] Advantage 2: The existing wire coil holder has an inverted "U" shaped groove at the bottom. First, insert the center rod of the wire coil holder into the center hole of the wire coil, and then place the entire wire coil holder on the strip tray, making it more convenient to pick up and put down.

[0077] The structure and operating principle of the warping machine of the present invention, as well as the method of feeding warp threads using the warping machine, will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0078] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the schematic diagram of the warping machine of the present invention, the warping machine includes a frame 2 with a central frame 1. Multiple rows of support rod groups 3 are fixedly arranged vertically on both sides of the central frame 1. Each row of support rod groups includes support rods 31 spaced at a certain distance. Rollers 4 are arranged on the frame outside the support rods 31. A yarn separating frame 5 is arranged in front of the frame 2. A strip-shaped support plate 6 is arranged above each row of support rod groups 3 in the front-back direction. A yarn spool fixing seat 7 is arranged above the strip-shaped support plate 6. 7 includes a base 71, a first annular groove 711 is provided on the upper surface of the base 71, a center limiting hole 712 is provided at the center of the base 71, an upper cover 72 is provided above the base 71, a center rod 721 is provided on the upper surface of the upper cover 72, a second annular groove 722 corresponding to the first annular groove 711 is provided on the lower surface of the upper cover 72, and a center limiting post 723 is provided at the center of the lower surface of the upper cover 72, the center limiting post 723 is inserted into the center limiting hole 712.
[0079] A pressure bearing 73 is provided between the first annular groove 711 and the second annular groove 722. Limiting blocks 713 are provided on both sides of the lower bottom surface of the base 71. A slot 714 is formed between the two limiting blocks 713. The width of the slot 714 is slightly larger than the width of the strip plate 6. The strip plate 6 is locked in the slot 714.
[0080] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the spool 8 is placed on the central rod 721. The spool 8 and the upper cover 72 are connected to the base 71 via a pressure bearing 73. The spool 8 rotates together with the upper cover 72 under the traction of the warp threads. When a malfunction occurs or the weaving length is reached, the warp threads stop being pulled, and the spool and the upper cover quickly stop rotating under the resistance of the pressure bearing 73, avoiding warp thread tangling caused by the spool not stopping rotating. The base 71 can be moved back and forth according to the diameter of the spool. When the warp threads on the spool 8 are not used up and a mesh with different warp diameters needs to be woven, the unused spool of warp threads can be moved forward or backward, and then the spool of warp threads with the required diameter can be placed on the central rod 721 of the adjacent spool fixing seat 7. The unused spool does not need to be removed, saving manpower and resources, reducing space occupation, and greatly improving production efficiency. Moreover, the spool is always flush with the roller, resulting in good wire feeding effect.
[0081] The slot 714 is an inverted "U" shape. The slot 714 is locked on the strip plate 6 and can be moved back and forth easily, but cannot be moved laterally. When the warp is basically in a lateral direction perpendicular to the warp's forward direction, it is more convenient to use.
[0082] A lower ejection through hole 715 communicating with the lower surface of the base is provided at the bottom of the first annular groove 711; an upper ejection through hole 724 communicating with the upper surface of the upper cover is provided at the top of the second annular groove 722. When the pressure bearing fails, it is easy to eject the pressure bearing from the first annular groove and the second annular groove, making it more convenient to use.
[0083] A method for feeding two warp yarns of different diameters using a warping machine, the method comprising the following steps:
[0084] The first step is to place the first type of warp yarn.
[0085] The first step is to conduct a tensile strength test.
[0086] The tensile strength of the first type of warp yarn to be placed is tested. The yarn spools that do not meet the tensile strength requirements are removed and used as weft yarns.
[0087] Step (2): Place the yarn roll
[0088] For the qualified spools, the first and second spools are placed on the center rods 721 of the two spool fixing seats 7 located at the front on the left and right sides. The subsequent spools are placed on the next spool fixing seat 7 that is spaced one spool fixing seat apart, and so on, until all the warp threads of the first type of wire diameter are placed.
[0089] The second step is to place the second type of warp yarn.
[0090] The first step is to conduct a tensile strength test.
[0091] The tensile strength of the warp yarns of the second type of yarn diameter to be placed is tested. The yarn spools that do not meet the tensile strength requirements are removed and used as weft yarns.
[0092] Step (2): Place the yarn roll
[0093] For the compliant spools, the first and second spools are placed on the center rods 721 of the two spool fixing seats 7 located at the front on the left and right sides, which are behind the spools of the first diameter. The spools that follow are placed on the next spool fixing seat 7 that is spaced one spool fixing seat 7 apart, and so on, until all the warp threads of the second diameter are placed.
[0094] The third step is to use the first type of yarn diameter warp yarn guide.
[0095] The warp ends of the first type of yarn are drawn out from the yarn spool, passed around the corresponding roller 4, and then through the splitting hole of the corresponding splitting frame 5 before being led out to the loom.
[0096] Step 4, the second type of wire diameter warp wire guide.
[0097] The warp end of the second type of wire diameter is led out from the wire spool, passes around the corresponding roller 4, passes through the wire splitting hole of the corresponding wire splitting frame, and is then fixed in front of the wire splitting frame by binding or other means.
[0098] Fifth step, adjust each wire reel fixing bracket.
[0099] Adjust the front and rear distances of each spool fixing seat 7 as needed so that the center rod 721 of the spool fixing seat where the two spools of the first type of wire diameter are located are on the same vertical plane as the roller corresponding to the spool.
[0100] Step 6: Weave using warp threads of the first diameter.
[0101] Turn on the loom and pull the warp yarns forward through the warp yarn traction mechanism. The warp yarns of the first yarn diameter are unspinned from the spool and woven together with the weft yarns on the loom to form a mesh.
[0102] Step 7: Replace with warp yarns of the second diameter.
[0103] When the length of the warp wire of the first wire diameter reaches the required length, the warp wire is cut off in front of the wire splitting hole of the wire splitting frame, and the front end of the warp wire is fixed on the corresponding wire splitting frame 5. Then the end of the warp wire of the second wire diameter is untied from the corresponding wire splitting frame 5 and stretched onto the loom.
[0104] Step 8: Adjust each wire reel holder.
[0105] Adjust the front and rear distances of each spool fixing seat 7 as needed so that the center rod 721 of the spool fixing seat where the two spools of the first type of wire diameter are located are on the same vertical plane as the roller corresponding to the spool.
[0106] Step 9: Weave using warp threads of the second diameter.
[0107] Turn on the loom and pull the warp yarns forward through the warp yarn traction mechanism. The warp yarns of the second diameter are unspinned from the spool and woven together with the weft yarns on the loom to form a mesh.
[0108] Step 10: Determine whether to replace the warp with a second diameter yarn, depending on the needs.
[0109] Depending on the required length of the woven mesh, decide whether to change to a different warp wire diameter.
[0110] For warp threads of different diameters: The method for feeding warp threads using a warping machine provided in this invention has the following advantages compared with the prior art:
[0111] Advantage 1: Different warp yarn diameters can be spaced on the center rod 721 of the yarn spool fixing seat 7. The end of the warp yarn of the first diameter is led out from the yarn spool, passes around the corresponding roller 4, and then through the splitting hole of the corresponding splitting frame 5 before being led out to the loom. The end of the warp yarn of the second diameter is led out from the yarn spool, passes around the corresponding roller 4, and then through the splitting hole of the corresponding splitting frame 5 before being led out and fixed in front of the splitting frame by binding or other means. When changing warp yarns of different diameters, it is not necessary to remove the yarn spool from the warping machine, transport it and put it in the warehouse. Instead, the unused warp yarn ends are directly fixed on the corresponding splitting frame. When used again, they can be directly led out from the splitting frame. This not only saves manpower and resources, but also reduces space occupation.
[0112] Advantage 2: The spool fixing seat 7 can move back and forth along the strip support plate 6. The distance between each spool fixing seat can be adjusted as needed, so that the center rod 721 of the spool fixing seat 7 where the two spools of the second batch of warp yarn are located is on the same vertical plane as the roller 4 corresponding to the spool; the spool is always flush with the roller 4, resulting in a good yarn feeding effect.
[0113] Advantage 3: Since the spool holder can move back and forth along the strip tray 6, there is no gap between each adjacent spool holder 7 on the strip tray 6. In this way, more spool holders can be placed on the warping machine of the same length.
[0114] For warp yarns of the same diameter, this includes both large-diameter spools of the same diameter and small-diameter spools of the same diameter. A method for feeding two types of small-diameter spools of the same diameter warp yarns using a warping machine includes the following steps:
[0115] The first step is to place the warp threads.
[0116] The first step is to conduct a tensile strength test.
[0117] The warp threads to be placed are subjected to tensile strength tests. The spools that do not meet the tensile strength requirements are removed and used as weft threads.
[0118] Step (2): Place the yarn roll
[0119] For the qualified spools, the first and second spools are placed on the center rods 721 of the two spool fixing seats 7 located at the front on the left and right sides, and the subsequent spools are placed on the adjacent spool fixing seats 7 in turn until all the warp threads are placed.
[0120] The second step is to introduce the first batch of warp threads.
[0121] Starting from the first spool holder 7 at the front end of the warping machine, the ends of all odd-numbered spool holders 7 are led out from the spool, pass around the corresponding roller 4, pass through the splitting hole of the corresponding splitting frame 5, and are led out to the loom.
[0122] The third step is to introduce the second batch of warp threads.
[0123] Starting from the second spool fixing seat 7 at the front end of the warping machine, the ends of all even-numbered spools 7 are led out from the spool, pass around the corresponding roller 4, pass through the splitting hole of the corresponding splitting frame 5, and are fixed in front of the splitting frame by binding or other means.
[0124] Fourth step, adjust each wire reel fixing bracket.

[0127] Turn on the loom, and the warp yarns are pulled forward by the warp yarn traction mechanism of the loom. The first batch of warp yarns are unspinned from the yarn spool and woven into a mesh with the weft yarns on the loom.
[0128] Step 6: While replacing the second batch of warp yarns, replace the used first batch of warp yarn spools with new spools, and complete the first batch of warp yarn lead-in.
[0129] After the first batch of warp yarns is used, the ends of the second batch of warp yarns are untied from the corresponding yarn splitter and stretched onto the loom. The ends of all odd-numbered yarns on the yarn splitter starting from the first yarn spool fixing seat 7 at the front of the warping machine are led out from the yarn spool, passed around the corresponding roller 4, passed through the yarn splitting hole of the corresponding yarn splitter 5, and then fixed in front of the yarn splitter by binding or other means.
[0130] Step 7: Adjust each wire reel holder.
[0131] Adjust the front and rear distances of each spool fixing seat 7 as needed so that the center rod 721 of the spool fixing seat 7 where the two spools of the second batch of warp yarn are located and the roller 4 corresponding to the spool are on the same vertical plane;

[0136] Step 10: Start repeating from step 4 until all weaving tasks are completed.
[0137] Of course, for small-diameter spools, all the spools located at the front can be placed on the spool holders for the first batch of warp threads, thus shortening the length of the warping machine.
[0138] For warp threads of the same diameter: the method for feeding warp threads using a warping machine provided by this invention has the following advantages compared with the prior art:
[0139] Advantage 1: For smaller diameter spools, more spool holders 7 can be placed on the strip tray 6. This means that twice the number of spool holders can be placed on the strip tray 6 at once, or the spool holders 7 can be placed only in the front half of the warping machine. The length of the warping machine can be shortened by half. When feeding the spools in the front half of the warping machine, the spools in the back half can be placed and led, greatly improving work efficiency. For larger diameter spools, the same principle applies, making it more versatile. One warping machine can handle the warp feeding of spools with various diameters.
[0140] Advantage 2: The existing wire coil fixing seat 7 has an inverted "U" shaped groove at the bottom. First, insert the center rod 721 of the wire coil fixing seat 7 into the center hole of the wire coil, and then place the entire wire coil fixing seat on the strip tray 6, which makes it more convenient to pick up and put down.
[0141] The scope of protection of this invention is not limited to the above embodiments. Any structure that is the same as or similar to the structure of the warping machine of this invention, or any method that is the same as or similar to the method of feeding warp threads using the warping machine, falls within the scope of protection of this invention.
