Description

Technical Field

[0001] This invention relates to the field of weaving equipment technology, and in particular to a high-stability wide-width weaving machine. Background Technology

[0002] The existing loom structures generally have the following problems: 1. The gearbox inside the right wall panel of the existing loom is prone to water ingress and damage. Because when the water jet loom is weaving, the water is sprayed from the left to the right. After reaching the right side, the water flow will continuously wash the output shaft of the weft insertion shaft and the output shaft of the transmission shaft of the gearbox on the right wall panel. The oil seals and water baffles of these two output shafts will age during long-term operation and adhere to the fallen yarn, which can easily get tangled on the output shaft of the transmission shaft, damaging the output shaft oil seal. The sizing material on the warp yarn will also accumulate inside the right water baffle and near the oil seal under the washing of water. Long-term operation will cause the water baffle to become blocked, and wastewater will accumulate near the output shaft, causing the oil seal to be soaked in water, resulting in poor oil seal lubrication and damage to the oil seal. This will cause water to enter the gearbox, and the parts inside the gearbox will be damaged due to water mixed with the lubricating oil, resulting in poor lubrication of the bearings and gears. 2. Existing looms, when weaving wide widths, rely solely on two sets of weft-beating systems within the gearboxes of the left and right side panels. This significantly reduces weft-beating force. When the weft-beating beam is over 2 meters long, its high-speed oscillation results in excessive vibration in the middle, further hindering weft-beating force and making it difficult to complete the weaving of the middle section of high-density fabrics. 3. Existing looms with flat sheaths have six gear drives within each of the left and right side panels, resulting in numerous parts, high cost, and complex maintenance. These gear drives cannot be eliminated when using cam sheaths or multi-arm sheaths, leading to wasted loom drive chains and increased manufacturing and operating costs. 4. In existing looms with flat sheaths, the drive components are located directly below the heald frame. During water-jet weaving, wastewater splashes directly onto these connecting rods and swing arms, causing rust over time and damage to connecting rod bearings and oil seals due to water ingress. The inventor's objective is to provide a highly stable wide width loom that overcomes the aforementioned technical problems. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the main purpose of this invention is to provide a high-stability wide-width loom with high strength, easy assembly, good waterproof performance, sufficient weft insertion force, meeting the needs of wide-width weft insertion, easy maintenance, low cost and simple and stable shedding mechanism.

The open gear is fixed on the open drive shaft, and bearings are provided at both ends of the open drive shaft. A crank is fixed at each end of the open drive shaft, and the cranks are clamped to the open drive shaft by bolts. The two cranks drive the long connecting rod and the short connecting rod respectively. Each end of the short connecting rod has a bearing and is pressed by connecting rod bearing cap one and connecting rod bearing cap two. Each end of the long connecting rod also has a bearing and is similarly pressed by connecting rod bearing cap two. The first connecting rod bearing cover and the second connecting rod bearing cover are pressed together. The short connecting rod and the long connecting rod respectively drive the two U-shaped swing arms to swing. The U-shaped swing arms are locked onto the upper open shaft and the lower open shaft respectively by locking screws. The upper open shaft is supported by a support bearing in a bearing housing composed of a large bearing housing 1 and a large bearing housing 2. The outer side of the support bearing has a first hole and an elastic retaining ring to limit the left and right position of the support bearing. The right side of the lower open shaft is provided with a spacer and an outer bearing support. The outer bearing is limited to its left and right position by an elastic retaining ring with a second hole. The right side of the locking sleeve is tightly pressed against the left side of the outer bearing. The upper and lower open shafts are in close contact, with a locking sleeve secured to the lower open shaft by a set screw. A first needle roller bearing is mounted on the lower open shaft. The outer ring of the first needle roller bearing is fixed within the lower bearing hole of a bearing housing composed of two large bearing seats and is restricted in its left and right positions by a third hole and an elastic retaining ring. A second needle roller bearing is provided on the right side of both the upper and lower open shafts. The second needle roller bearings are restricted in their left and right positions by a fourth hole and an elastic retaining ring. Both the fourth hole, the elastic retaining ring, and the second needle roller bearing are located within two bearing holes on the left side bearing seat of the open shaft.

[0005] Preferably, the middle weft insertion shaft is fixedly connected to the reed seat through one or more long weft insertion feet, and the side weft insertion shaft and the weft insertion shaft eccentric coupling are fixedly connected to the reed seat through one or more short weft insertion feet. Both the long and short weft insertion feet are connected to the reed seat through fixing bolts.

[0006] Preferably, the right wall panel is provided with an inner bearing for the main shaft and an outer bearing for the main shaft that cooperate with the right tapered main shaft.

[0007] Preferably, a connecting rod cover is fixedly connected to the connecting rod by fastening screws.

[0008] Preferably, the middle support seat of the left open shaft is provided with an elongated hole, and the middle support bearing seat of the open shaft can move back and forth along the direction of the elongated hole and be fixed by adjusting the fixing bolt.

[0009] Preferably, the U-shaped swing arm is provided with a long groove that is locked by a locking nut, and the bearing at the lower end of the long connecting rod can move back and forth along the long groove. The end of the long groove is provided with a bolt for locking and a middle spacer for intermediate support.

[0010] Preferably, a small bearing seat is provided on the lower open shaft, and the U-shaped swing arm is fixedly connected to the small bearing seat by a locking screw.

[0011] Preferably, the bottom of the weft insertion box is connected to an intermediate support, the intermediate support is provided with a plurality of hollow weight-reducing holes and a plurality of structural reinforcing ribs arranged along the edge of the hollow weight-reducing holes, the intermediate support is fixedly connected to the front lower support and the rear lower support by fixing bolts, and the bottom of the weft insertion box is fixedly connected to the intermediate support by fixing bolts.

[0012] Preferably, a cable is threaded through the rear lower support.

[0013] Preferably, the bottom of the left wall panel, the right wall panel, the front lower support, and the rear lower support are each provided with a plurality of foot auxiliary brackets, and foot bolts are threaded onto the foot auxiliary brackets. The foot bolts are connected to the foot auxiliary brackets by fixing nuts.

[0014] Compared with the prior art, the present invention has the following advantages: the left and right wall panels of the loom frame structure are each divided into upper and lower parts, which facilitates casting and processing during the manufacturing process. The four supports of the loom are rectangular and square steel pipes, which have good rigidity, high strength, and strong bending resistance, thus resulting in low vibration and smooth operation when the loom is running at high speed.

[0015] Two or more weft insertion boxes are fixed on the front upper support. Two or more intermediate supports are connected to the bottom surface of each weft insertion box. The side of the intermediate support is connected to the platform welded on the front lower support. The intermediate support is connected to the rear lower support through an auxiliary support. The top plane of the intermediate support is connected to the bottom surface of the rear upper support. When the three supports (front upper support, front lower support, and rear upper support) are connected to each plane of the intermediate support, they are all precisely machined surfaces. This connection ensures the connection accuracy and rigidity of the frame.

[0016] The modular design integrates the beat-up mechanism into the beat-up box. In wide-width or heavy-duty fabric weaving, multiple beat-up systems can be set up to improve beat-up strength. This beat-up system has fewer internal parts, strong versatility, and convenient maintenance. When internal parts are damaged, only the bearings and rotating parts of the bearing bush can be replaced, resulting in low maintenance costs. In addition, the beat-up box is small in size and shape, which reduces manufacturing costs and the amount of lubricating oil used, thus reducing the operating costs for customers in the later stage.

[0017] The right wall panel on the right side of the loom does not have a transmission gear for the flat opening mechanism; only the main shaft bearing needs lubrication. This structure is simple, easy to maintain, and greatly reduces the amount of lubricating oil used, saving subsequent operating costs.

[0018] The flat sheath transmission structure of the loom has a reasonable structural design. Compared with the existing technology, it uses fewer parts, has lower cost, and is easy to maintain and repair. The connection between each component is stable and efficient, and the use of multiple different bearing caps can ensure the connecting rod bearings and extend the service life of the mechanism.

Each of the right opening shaft intermediate support seat 60 and the left opening shaft intermediate support seat 61 is fixed with an opening shaft intermediate support bearing seat 62. Each of the two opening shaft intermediate support bearing seats 62 is equipped with an opening shaft intermediate support bearing cover 59. The upper opening shaft 57 and the lower opening shaft 58 can rotate along the bearing bush 40 in the inner hole of the opening shaft intermediate support bearing seat 62. The left tapered main shaft 19 is supported by the bearing hole of the gearbox cover 85 and the opening main shaft bearing housing by the outer bearing 71 and the inner bearing 81 of the main shaft, respectively. On the bearing hole of 86, a main shaft drive gear 82 capable of driving the open gear 84 to rotate is fixed on the left tapered main shaft 19. The open gear 84 is fixed on the open drive shaft 83. Each end of the open drive shaft 83 is provided with a bearing support. Each end of the open drive shaft 83 is fixed with a crank 53. The cranks 53 are clamped to the open drive shaft 83 by bolts. The two cranks 53 respectively drive the long connecting rod 65 and the short connecting rod 54.

[0041] Preferably, the right wall panel 3 is provided with an inner bearing 81 and an outer bearing 80 of the main shaft that cooperate with the right tapered main shaft 18.

[0042] Preferably, a connecting rod cover 50 is fixedly connected to the connecting rod 41 by fastening screws.

[0043] Preferably, the left open shaft intermediate support 61 is provided with an elongated hole, and the open shaft intermediate support bearing 62 can move back and forth along the direction of the elongated hole and be fixed by the adjusting fixing bolt 63.

[0044] Preferably, the U-shaped swing arm 66 is provided with a long groove that is locked by a locking nut, and the bearing at the lower end of the long connecting rod 65 can move back and forth along the long groove. The end of the long groove is provided with a bolt for locking and a middle spacer sleeve 56 for intermediate support.

[0045] Preferably, a small bearing seat 67 is provided on the lower open shaft 58, and the U-shaped swing arm 66 is fixedly connected to the small bearing seat 67 by a locking screw.

[0046] Preferably, the bottom of the weft insertion box 22 is connected to an intermediate support 12. The intermediate support 12 is provided with a plurality of hollow weight-reducing holes and a plurality of structural reinforcing ribs arranged along the edge of the hollow weight-reducing holes. The intermediate support 12 is fixedly connected to the front lower support 9 and the rear lower support 11 by fixing bolts. The bottom of the weft insertion box 22 is fixedly connected to the intermediate support 12 by fixing bolts.

[0047] Preferably, a cable is threaded through the rear lower support 11.

[0048] Preferably, the bottom of the left wall panel 2, the right wall panel 3, the front lower support 9, and the rear lower support 11 are each provided with a plurality of foot auxiliary brackets 13, and foot bolts 14 are threadedly connected to the foot auxiliary brackets 13, and the foot bolts 14 are connected to the foot auxiliary brackets 13 by fixing nuts.

[0049] In this design, the left wall panel 2 and right wall panel 3 of the loom frame 1 are each divided into upper and lower sections, facilitating casting and machining during the manufacturing process. The four supports of the loom are rectangular and square steel pipes, which provide good rigidity, high strength, and strong bending resistance, resulting in low vibration and smooth operation when the loom is running at high speed.

[0050] Two or more weft insertion boxes 22 are fixed on the front upper support 8. The bottom surface of each weft insertion box 22 is connected to two or more intermediate supports 12. The side of the intermediate support 12 is connected to the platform welded on the front lower support 9. The intermediate support 12 is connected to the rear lower support 11 through an auxiliary support. The top plane of the intermediate support 12 is connected to the bottom surface of the rear upper support 10. When the supports of the front upper support 8, the front lower support 9 and the rear upper support 10 are connected to each plane of the intermediate support 12, they are all precisely machined surfaces. This connection ensures the connection accuracy and rigidity of the frame 1.

[0051] Both the front lower support 9 and the rear lower support 11 have threaded holes on their outer sides and multiple base auxiliary brackets 13 and base bolts 14 for connection to the horizontal ground. The base auxiliary brackets 13 can be adjusted up and down when connected to the ground to adapt to ground height errors. After the loom is leveled, slightly loosen the locking screws on the side of the base auxiliary bracket 13 and the front lower support 9 and the rear lower support 11, adjust the base auxiliary bracket 13 to be tightly connected to the horizontal ground, tighten the base bolts 14, and then tighten the bolts between the base auxiliary bracket 13 and the support.

[0052] When the two ends of the front upper support 8, the front lower support 9, and the rear upper support 10 are connected to the left wall panel 2 and the right wall panel 3, they are all connected from the outside of the wall panel with bolts and positioning bolts, which facilitates assembly. At the same time, since the holes on the wall panel are all smooth holes and the threaded holes on the end face of the support are blind holes, the threaded holes will not be damaged due to rust and corrosion caused by long-term water ingress. In addition, stainless steel bolts are not required for this connection, and conventional rust prevention measures can be taken, which can greatly reduce manufacturing costs.

[0053] The rear lower support 11 is a rectangular steel pipe without end caps at both ends. When connecting the lower left wall panel 5 and the lower right wall panel 7, it prevents the surfaces of the lower left wall panel 5 and the lower right wall panel 7 from being misparallel due to errors in the length of the support. The hollow structure of the rectangular tube of the rear lower support 11 allows the high-voltage cables and various signal cables of the loom to pass through and be protected inside the rear lower support 11. This protects the cables from damage during the transportation, loading, unloading, and maintenance of the loom, and also eliminates concerns about long-term exposure to sunlight causing aging and cracking of the cable sheath, which could lead to leakage accidents. This ensures the electrical safety of the loom.

[0054] The front upper support 8 is made of a square steel tube with a large cross-section. A rectangular steel plate, approximately the same length as the square steel tube, is welded to its top surface. This steel plate has multiple threaded holes for assembling parts of the fabric support frame. This surface is machined in one go to ensure flatness, thus guaranteeing the precision of the assembly of the fabric support frame parts. Simultaneously, multiple platforms are welded to the rear side and bottom of the square tube of the front upper support 8, connecting to the weft insertion box 22. The horizontal and vertical surfaces connect to the horizontal and vertical surfaces of the weft insertion box 22, respectively. This structure provides high connection strength and accurate positioning, ensuring the precision of each connecting component in the weft insertion system. This guarantees the high-speed operation of the loom's weft insertion system, ensuring the smooth weaving of high-density and high-quality fabrics.

[0055] For the weft insertion mechanism, the right wall panel 3 and the left wall panel 2 are connected together by the front upper support 8. The right tapered main shaft 18 is connected to the right connecting main shaft 21 through the main shaft coupling 24. The right connecting main shaft 21 is then connected to the weft insertion box main shaft 23 through the main shaft coupling 24. There is a weft insertion box main shaft 23 bearing at each end of the weft insertion box main shaft 23. The weft insertion box main shaft 23 is then connected to the middle main shaft 20 through the main shaft coupling 24. The middle main shaft 20 is then connected to the weft insertion box main shaft 23 through the main shaft coupling 24. Similarly, there is a weft insertion box bearing at each end of the weft insertion box main shaft 23. The weft insertion box main shaft 23 is then connected to the left connecting main shaft 21 through the main shaft coupling 24.

[0056] The upper front support 8 has one or more sets of weft insertion boxes 22 composed of the right box and the left box. Inside the weft insertion box 22, there are various linkage weft insertion or cam weft insertion that drive the right weft insertion shaft, the middle weft insertion shaft 27 and the left weft insertion shaft to swing synchronously to form the weft insertion motion.

[0057] There is one or more sets of auxiliary support bearing seats 30 on the right weft insertion shaft. Similarly, there is one or more sets of auxiliary support bearing seats 30 on the left side of the weft insertion shaft. The right side of the right eccentric weft insertion shaft coupling is connected to the right side of the right weft insertion shaft, and the left side is connected to the right side of the middle weft insertion shaft 27. The left side of the middle weft insertion shaft 27 is connected to the right side of the left eccentric weft insertion shaft coupling, and the left eccentric weft insertion shaft coupling is connected to the left weft insertion shaft. One or more short weft insertion feet 49 are clamped to the right side of the right weft insertion shaft by bolts. One or more short weft insertion feet 49 are clamped to the left weft insertion shaft. One or more long weft insertion feet 48 are clamped to the middle weft insertion shaft 27.

[0058] The original loom's main drive consisted of a gearbox in each of the left and right wall panels 3. The gearbox contained the weft insertion system and various gear transmission systems, which was complex and expensive. If water or oil leaked into the gearbox, it would be damaged and all the rotating parts inside would become inoperable, requiring replacement. This resulted in high maintenance costs and long downtime.

[0059] The two symmetrical and corresponding components of the weft insertion box, namely the left box body 31 and the right box body 32, are positioned by two positioning pins to ensure the coaxiality of the support holes 35 of the connecting rod shafts of the left box body 31 and the right box body 32, and are fixed by fixing screws. The contact surfaces of the left box body 31 and the right box body 32 are sealed with sealant to ensure the airtightness of the weft insertion box.

[0060] The left housing 31 and the right housing 32 each have a rectangular opening, which, when combined, forms the main observation window 36. The main observation window 36 facilitates internal maintenance of the weft winding box and is sealed with a cover secured by screws. Both the left housing 31 and the right housing 32 have auxiliary observation windows. The connecting surface between the cover of the main observation window 36 and the left housing 31 and the right housing 32 is a recessed mounting groove, and the mounting surface of the cover of the main observation window 36 is coated with sealant to seal the plane.

[0061] The transmission structure is housed within the left housing 31 and right housing 32. Its principle is as follows: the internal crankshaft 38 is fixed within the main shaft bearing hole 34 at the bottom of the left and right housings 31 and 32 via a main shaft bearing 37. The crankshaft 38 is connected to the connecting rod 41 via a bearing bush 40 at its eccentric shaft 39. The connecting rod cover 50 is fixed to the connecting rod 41 with four fastening screws. A bushing bearing 42 is mounted on the connecting rod 41, and it is connected to the rocker arm 44 via a connecting rod pin 43, which is secured with a fastening screw. The weft-beating shaft 45 has a key and is fixed to the rocker arm 44 end hole 46 by two fastening screws. The weft-beating shaft 45 is fixed within the weft-beating shaft hole at the top of the left and right housings 31 and 32 via a weft-beating shaft bearing 47. Rotation of the crankshaft 38 drives the connecting rod 41 and the weft-beating shaft 45 to swing, thus achieving the weft-beating motion. This structure is compact and convenient for production, maintenance, and repair. Depending on the length requirements, the weft insertion shaft 45 and the weft insertion box main shaft 23 can be the same weft insertion shaft or different connected weft insertion shafts.

[0062] The flat sheath transmission structure of the loom in this solution has a reasonable structural design. Compared with the existing technology, it uses fewer parts, has lower cost, and is easy to maintain and repair. The connection between each component is stable and efficient, and the use of multiple different bearing caps can ensure the connecting rod bearings and extend the service life of the mechanism.

[0063] This new type of transmission is a modular design that integrates the beat-up mechanism into the beat-up box 22. In wide-width weaving or heavy fabric weaving, multiple beat-up systems can be set up to improve the beat-up force. The beat-up box has fewer internal parts, strong versatility, and convenient maintenance. When internal parts are damaged, only the bearings and rotating parts of the bearing bush 40 need to be replaced, resulting in low maintenance costs. In addition, the beat-up box is small in size and shape, which reduces manufacturing costs and the amount of lubricating oil used, thus reducing the operating costs in the later stages of use.
