Description

Technical Field

[0001] This invention relates to the field of weaving equipment technology, and in particular to a multi-link beating box structure. Background Technology

[0002] The function of the beat-up mechanism is to convert the uniform rotational motion of the loom spindle into the non-uniform oscillation of the reed. This requires the reed to have a pause or "near pause" time at its rear center position to allow sufficient time for weft insertion. Existing loom beat-up boxes are primarily a single, integrated structure with other components assembled together. While this provides high structural strength, it also makes disassembly and assembly difficult, resulting in cumbersome assembly and maintenance of the transmission structure. Furthermore, existing looms exhibit insufficient beat-up force during wide-width weaving. When the beat-up beam is over 2 meters long, its high-speed oscillation causes excessive vibration in the middle, resulting in unstable movement and insufficient beat-up force. This makes it difficult to complete the weaving of the middle section of high-density fabrics, and the loom requires less time for weft insertion, which is detrimental to wide-width looms and multi-nozzle weaving. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the main objective of this invention is to provide a multi-link weft insertion box structure that is compact, has a large weft insertion force, and moves smoothly.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-link weft insertion box structure, comprising a left box and a right box arranged symmetrically, the left box and the right box being connected by fixing screws, and both the left box and the right box having a weft insertion shaft bearing hole, a crankshaft bearing hole, and a rocker arm fixing shaft support hole that are provided through and coaxially; a crankshaft is connected to the crankshaft bearing hole by two crankshaft bearings, and the crankshaft is rotatably connected to the crankshaft connecting rod by a bearing bush at the eccentric position of the journal, the connection end between the crankshaft connecting rod and the bearing bush being a two-lobed retainer. The structure comprises a two-lobed retaining structure connected by fixing screws. The crankshaft connecting rod has a fork-shaped structure at one end relative to the two-lobed retaining structure. This fork-shaped structure includes two coaxial inner holes, each containing a connecting rod bushing bearing. A lower connecting shaft is housed within each connecting rod bushing bearing and can rotate along it. A lower rocker arm is located diagonally below the crankshaft connecting rod. Above the lower rocker arm, two coaxial holes connect the lower connecting shaft, each secured with a fixing screw. The lower rocker arm has two lower rocker arm bearings installed in the hole below it. Each of the two lower rocker arm bearings houses a rocker arm fixing shaft. Both ends of the rocker arm fixing shaft are fixed to the rocker arm fixing shaft support holes of the left and right weft insertion boxes. The system also includes an intermediate connecting rod connecting the lower rocker arm and the weft insertion shaft rocker arm. Each end of the intermediate connecting rod has a bearing installed in its inner hole. One end of the intermediate connecting rod is connected to the middle part of the lower connecting shaft of the connecting rod and can rotate through the bearing. The other end of the intermediate connecting rod is connected to a coaxial hole at the lower end of the weft insertion shaft rocker arm through the upper connecting shaft of the connecting rod. The weft insertion shaft is clamped by two fixing screws and is fixedly connected to the weft insertion shaft rocker arm. The weft insertion shaft is connected to the weft insertion shaft bearing holes in the left and right weft insertion boxes respectively through two bearings. The crankshaft drives one end of the two-lobed retaining structure of the crankshaft connecting rod to rotate. The other end of the crankshaft connecting rod drives the lower rocker arm and the middle connecting rod to move. The movement of the middle connecting rod simultaneously drives the weft insertion shaft rocker arm to reciprocate along the weft insertion shaft axis. The movement of the weft insertion shaft rocker arm simultaneously drives the weft insertion shaft to realize the weft insertion movement.

[0005] Preferably, the weft insertion shaft and the weft insertion shaft rocker are locked together by a flat key.

[0006] Preferably, the contact surfaces of the left and right housings are provided with sealant.

[0007] Preferably, both the left and right boxes have rectangular openings on their front sides, and the two rectangular openings form a main observation window, which is covered with a main observation window cover.

[0008] Preferably, the left and right boxes are respectively provided with a vertical fixing surface and a horizontal fixing surface that are connected to the front upper support.

[0009] This invention has the following advantages over the prior art: the two symmetrical and corresponding components of the beating box, namely the left box body and the right box body, are positioned by two locating pins to ensure the coaxiality of the holes in the left and right box bodies, and are fixed by fixing screws. The contact surfaces of the left and right box bodies are sealed with sealant, thus ensuring the airtightness of the beating box. Each of the left and right box bodies has a rectangular opening, which, when combined, forms a main observation window. The main observation window facilitates internal maintenance of the beating box and is sealed with a main observation window cover fixed by screws. Both the left and right box bodies have secondary observation windows. The connecting surface between the main observation window cover and the left and right box bodies is a recessed mounting groove, and the mounting surface of the main observation window cover is coated with sealant to seal this plane.

[0010] The working process of this beat-up mechanism is as follows: the crankshaft drives one end of the two-lobed retaining structure of the crankshaft connecting rod to rotate, while the other end of the crankshaft connecting rod drives the lower rocker arm and the intermediate connecting rod. Simultaneously, the movement of the intermediate connecting rod causes the beat-up shaft rocker arm to reciprocate along the beat-up shaft axis. Since the beat-up shaft and the beat-up shaft rocker arm are locked together by a flat key, the movement of the beat-up shaft rocker arm simultaneously drives the beat-up shaft to achieve the beat-up motion. This design features a compact structure, smooth movement, high beat-up force, low vibration, and low inertia, thus reducing energy consumption. It is suitable for beat-up on high-speed looms. This beat-up mechanism extends the time required for weft insertion on the loom, which is beneficial for weft insertion on wide-width looms and multi-nozzle weaving.

[0011] In this multi-link beat-up mechanism, the crankshaft, beat-up shaft, and lower rocker fixed shaft are coaxially arranged, making the structure more compact. The lower rocker acts as a support in the structure, reducing the overall volume of the beat-up box and making the movement more stable. The pause time of the beat-up shaft driving the reed is extended, which makes the swing curve and displacement curve of the beat-up shaft suitable for the weft insertion and multi-nozzle weaving requirements of wide-width looms. The acceleration curve of the beat-up shaft during swing is smoother, and the maximum acceleration is smaller than that of existing technologies, so its inertia is smaller and energy consumption is reduced.

[0021] like Figure 1As shown, a multi-link weft insertion box structure includes a left box 1 and a right box 2 arranged symmetrically. The left box 1 and the right box 2 are connected by fixing screws. Both the left box 1 and the right box 2 have a weft insertion shaft bearing hole 3, a crankshaft bearing hole 4, and a rocker arm fixing shaft support hole 5, which are provided through and coaxially. A crankshaft 6 is connected to the crankshaft bearing hole 4 by two crankshaft bearings 7. The crankshaft 6 is rotatably connected to the crankshaft connecting rod 10 at the journal eccentricity 8 by a bearing bush 9. The connection end between the crankshaft connecting rod 10 and the bearing bush 9 is a two-lobed retaining structure 11. The two-lobed retaining structure 11 is fixed by... The crankshaft connecting rod 10 is connected by a fixed screw. One end of the crankshaft connecting rod 10 opposite the two-lobed retaining structure 11 is a fork-shaped structure 12. The fork-shaped structure 12 includes two coaxial inner holes, each containing a connecting rod bushing bearing 13. A lower connecting shaft 14 is located within each connecting rod bushing bearing 13 and can rotate along it. A lower rocker arm 15 is located diagonally below the crankshaft connecting rod 10. The lower rocker arm 15 is connected above two coaxial holes via the lower connecting shaft 14 and clamped by a fixed screw. Two lower rocker arm bearings 16 are installed inside the square hole. Rocker arm fixing shafts 17 are installed inside the two lower rocker arm bearings 16. The two ends of the rocker arm fixing shafts 17 are fixed inside the rocker arm fixing shaft support holes 5 of the left and right weft insertion boxes. The system also includes an intermediate connecting rod 18 connecting the lower rocker arm 15 and the weft insertion shaft rocker arm 20. Each end of the intermediate connecting rod 18 has a bearing in its inner hole. One end of the intermediate connecting rod 18 is connected to the middle part of the lower connecting shaft 14 of the connecting rod and can rotate through the bearing. The other end of the intermediate connecting rod 18 is connected to a coaxial hole at the lower end of the weft insertion shaft rocker arm 20 through the upper connecting shaft 19 of the connecting rod, and is fixed by two bearings. The weft insertion shaft and the weft insertion shaft rocker arm 20 are fixedly connected by two fixing screws. The weft insertion shaft 21 is connected to the weft insertion shaft bearing holes 3 in the left and right weft insertion boxes through two bearings respectively. The crankshaft 6 drives one end of the two-lobed retaining structure 11 of the crankshaft connecting rod 10 to rotate. The other end of the crankshaft connecting rod 10 drives the lower rocker arm 15 and the middle connecting rod 18 to move. The movement of the middle connecting rod 18 simultaneously drives the weft insertion shaft rocker arm 20 to reciprocate along the axis of the weft insertion shaft 21. The movement of the weft insertion shaft rocker arm 20 simultaneously drives the weft insertion shaft 21 to realize the weft insertion movement.

[0022] Furthermore, the weft insertion shaft 21 and the weft insertion shaft rocker arm 20 are locked together by a flat key 23.

[0023] Furthermore, the contact surfaces of the left housing 1 and the right housing 2 are provided with sealant.

[0024] Furthermore, both the left box 1 and the right box 2 have rectangular openings on their front sides, and the two rectangular openings form a main observation window 22, which is covered with a main observation window cover.

[0025] Furthermore, the left housing 1 and the right housing 2 are respectively provided with a vertical fixing surface and a horizontal fixing surface connected to the front upper support.

[0026] This solution presents a multi-link weft insertion box structure, in which two symmetrical and corresponding components, the left box 1 and the right box 2, are positioned by two locating pins to ensure the coaxiality of all holes in the left box 1 and the right box 2, and are fixed by fixing screws. The contact surfaces of the left box 1 and the right box 2 are sealed with sealant to ensure the airtightness of the weft insertion box. Each of the left box 1 and the right box 2 has a rectangular opening, which, when combined, forms a main observation window 22. The main observation window 22 facilitates internal maintenance of the weft insertion box and is sealed with a main observation window cover by screws. Both the left box 1 and the right box 2 have auxiliary observation windows. The connecting surface between the main observation window cover and the left box 1 and the right box 2 is a recessed mounting groove, and the mounting surface of the main observation window cover is coated with sealant to seal this surface.

[0027] The working process of this beat-up mechanism is as follows: the crankshaft 6 drives one end of the two-lobed retaining structure 11 of the crankshaft connecting rod 10 to rotate, while the other end of the crankshaft connecting rod 10 drives the lower rocker arm 15 and the intermediate connecting rod 18. The movement of the intermediate connecting rod 18 simultaneously drives the beat-up shaft rocker arm 20 to reciprocate along the axis of the beat-up shaft 21. Since the beat-up shaft 21 and the beat-up shaft rocker arm 20 are locked together by a flat key 23, the movement of the beat-up shaft rocker arm 20 simultaneously drives the beat-up shaft 21 to achieve the beat-up motion. This design has a compact structure, smooth movement, large beat-up force, low vibration, and low inertia, thus reducing energy consumption. It is suitable for beat-up on high-speed looms. This beat-up mechanism extends the time required for weft insertion on the loom, which is beneficial for weft insertion on wide-width looms and multi-nozzle weaving.

[0028] In this multi-link beat-up mechanism, the crankshaft 6, beat-up shaft 21, and rocker fixed shaft 17 are coaxially arranged, making the structure more compact. The lower rocker 15 plays a supporting role in the structure. While reducing the overall volume of the beat-up box, the movement is more stable. The pause time of the beat-up shaft 21 driving the reed is extended, which makes the swing curve and displacement curve of the beat-up shaft 21 suitable for the weft insertion and multi-nozzle weaving requirements of wide-width looms. The acceleration curve of the beat-up shaft 21 when swinging is smoother, and the maximum acceleration is smaller than that of the existing technology. Therefore, its inertia is smaller and energy consumption is reduced.
