Description

Technical Field

[0001] This invention relates to the field of warp knitting machine technology, and in particular to a warp knitting process and a warp knitting machine for warp knitting mesh fabric for automobile seats. Background Technology

[0002] Since warp-knitted mesh fabric for car seats is an important component of car interiors and comes into direct contact with the human body, surface quality is extremely important and defects must be eliminated. This mesh fabric is woven using a warp knitting machine, where one or more sets of parallel yarns are fed into all the working needles of the machine in the warp direction to form loops and create a knitted fabric.

[0003] Warp knitting machines are mature equipment, mainly composed of a knitting mechanism, a comb bar traverse mechanism, a warp feeding mechanism, a pull-and-wind mechanism, and a transmission mechanism.

[0004] The knitting mechanism includes the needle bed, sinker bed, and pressure plate, and is generally driven by cams or eccentric linkages. Cams are commonly used in warp knitting machines with lower speeds and more complex motion patterns of the loop-forming parts. Eccentric linkages are widely used in high-speed warp knitting machines because of their smooth transmission, simpler manufacturing process, and lower wear and noise at high speeds.

[0005] The guide bar lateral movement mechanism moves the guide bars laterally according to the requirements of the knitted fabric structure during loop formation, placing the warp yarns on the needles to knit a fabric with a specific structure. There are generally two types: pattern plate type and cam type. The pattern plate type mechanism uses pattern plates of a specific shape and size linked together to form a pattern plate chain according to the requirements of the knitted fabric structure, causing the guide bars to move laterally. It is suitable for knitting more complex patterns and allows for convenient pattern changes. In the cam type mechanism, the cams are designed according to the guide bar lateral movement pattern required by the knitted fabric structure, resulting in smoother transmission and the ability to adapt to higher knitting speeds.

[0006] The warp feeding mechanism unloads the warp yarns from the warp beam and feeds them into the weaving area. The function of the pull-and-take mechanism is to pull the fabric out of the weaving area at a predetermined speed and wind it into a roll.

[0007] Accurately controlling the lateral movement of the guide bar is a crucial step in ensuring proper yarn padding. Inaccurate lateral movement of the guide bar can easily lead to yarn padding failure and defects. Summary of the Invention

[0041] The following is combined with Figure 1 — Figure 7 As shown, this embodiment provides a warp knitting machine for automotive seat mesh fabric, comprising a frame 1, a knitting system 2, a guide bar traverse system 3, a warp feeding system, a pull-and-take system, and a transmission system 4. The knitting system 2 is vertically and flexibly mounted on the frame 1, and the lifting and lowering of the knitting system 2 enables the yarn to form loops. The transmission system 4 is mounted on the frame 1 and is connected to the knitting system 2, driving the knitting system 2 to lift and lower. The guide bar traverse system 3 is mounted on the frame 1 and is installed on the upper side of the knitting system 2. The lateral movement of the guide bar traverse system 3 causes the yarn to wrap around the knitting system 2. The warp feeding system is installed on the upper side of the frame 1 to supply yarn to the guide bar traverse system 3, so that when the guide bar traverse system 3 moves horizontally around the knitting system 2, the yarn is pulled out from the position of the warp feeding system. The pull-and-take system is mounted on the frame 1 and pulls away the fabric woven by the knitting system 2.

[0042] The guide bar traverse system 3 includes a traverse cam device 31, a swing lever 32, a traverse roller device 33, an indexing seat 34, and a guide bar plate 35. The indexing seat 34 is mounted on the frame 1 via a reference shaft 36. The guide bar plate 35 is slidably mounted on the indexing seat 34. The reference shaft 36 is rotatably mounted on the frame 1 via bearings, enabling the guide bar plate 35 to oscillate in a direction perpendicular to the direction of the needle bed plate 21 (mentioned below). While the guide bar plate 35 has the ability to traverse along the indexing seat 34, it can also traverse longitudinally on the upper side of the knitting system 2 to achieve yarn padding. Several yarn guide needles with yarn threaded through them are provided on the lower side of the guide bar plate 35. When the comb plate 35 moves laterally, it drives the yarn to wrap around the braiding system 2 and pad the yarn. The transverse cam device 31 is rotatably mounted on the frame 1, the swing lever 32 is rotatably mounted on the frame 1, and the transverse roller device 33 is rotatably mounted on the swing lever 32. The transverse roller device 33 rolls along the outer surface of the transverse cam device 31. When the transverse cam device 31 rotates, the transverse roller device 33 rolls along the outer surface of the transverse cam device 31, thereby driving the swing lever 32 to swing. The swing lever 32 is connected to the comb plate 35 through a transmission, driving the comb plate 35 to move laterally along the indexing seat 34, so that the comb plate 35 drives the yarn to wrap around the braiding system 2 and pad the yarn.

[0043] The transverse roller device 33 includes an inflatable roller 331, a push shaft 332, a hollow shaft 333, and several support frames 334. The inflatable roller 331 is sealed and fitted outside the hollow shaft 333. The inflatable roller 331 is inflated according to the degree of wear, so that the swing angle of the swing lever 32 is precise, ensuring reliable yarn padding and preventing defects in the warp-knitted mesh. The push shaft 332 is rotatably mounted inside the hollow shaft 333 via a pin. The rotation axis of the push shaft 332 coincides with the rotation axis of the hollow shaft 333. A torsion spring is provided between the push shaft 332 and the hollow shaft 333. A push rod pushing inclined surface is provided on the outside of the push shaft 332. Each support... The frame 334 is slidably mounted on the hollow shaft 333. Each support frame 334 is connected to the corresponding push inclined surface of the hollow shaft 333. After the air wheel 331 is inflated, its diameter expands. Each support frame 334 loses the support of the inner wall of the air wheel 331. The push shaft 332 rotates with the expansion of the air wheel 331 under the drive of the torsion spring. After the air wheel 331 is inflated, the push shaft 332 pushes the support frame 334 to the outside of the air wheel 331, so that each support frame 334 maintains pressing against the inner wall of the air wheel 331, maintains the outer diameter of the air wheel 331, ensures the accuracy of the transverse position of the comb plate 35, and prevents defects.

[0044] The knitting system 2 includes a needle bed plate 21, a loop release plate 22, a sinker plate, and several knitting needles 23. Each knitting needle 23 is mounted on the needle bed plate 21, which is mounted on the frame 1 in a height-adjustable manner. The needle bed plate 21 is connected to the transmission system 4 to achieve lifting and lowering. The loop release plate 22 is mounted on the frame 1, and each knitting needle 23 slides up and down along the loop release plate 22. When the knitting needle 23 descends, the loop release plate 22 supports the loop to facilitate loop formation. The sinker plate slides horizontally along the needle bed plate 21. When each knitting needle 23 is rising and is unwinding, the sinker plate extends to press down on the old loop to prevent the old loop from following the knitting needle 23 upwards. The cooperation of the knitting needle 23, the loop release plate 22, and the sinker plate achieves loop formation. This is a commercially available prior art and will not be described in detail here.

[0045] The warp feeding system includes several warp beams and spindles, which supply yarn when the combing system 3 padded the yarn.

[0046] The traction and winding system includes a winding shaft and a winding motor. The winding shaft is rotatably mounted on the frame 1, and the winding motor is mounted on the frame 1. The winding shaft and the winding motor are connected in a drive connection to realize the winding of the formed fabric.

The transmission cam drive shaft 41 is rotatably mounted on the frame 1. The lifting crankshaft 42 is connected to the transmission cam drive shaft 41. The transmission cam drive shaft 41 is provided with a cam structure formed by a guide groove. The lifting crankshaft 42 is provided with a guide wheel that matches the guide groove. The guide wheel is rotatably mounted on a pre-set transmission arm of the lifting crankshaft 42. The two ends of the lifting connecting rod 43 are respectively rotatably mounted on the transmission arm of the lifting crankshaft 42 and the weaving system 2. When the transmission cam drive shaft 41 rotates, the guide groove rotates accordingly, and the guide wheel moves along the direction of the guide groove, causing the pre-set transmission arm of the lifting crankshaft 42 to swing back and forth, thereby realizing the reciprocating lifting and lowering of the weaving system 2 and realizing the weaving of loops.

[0048] The transverse cam device 31 includes a transverse wheel 311, a chain block 312, and a transverse drive motor. The chain block 312 is mounted on the transverse wheel 311, and the transverse drive motor is mounted on the frame 1. The transverse wheel 311 is rotatably mounted on the frame 1. The transverse drive motor is connected to the transverse wheel 311 for transmission, thereby driving the transverse wheel 311 to rotate. The pneumatic wheel 331 rolls along the surface of the chain block 312, and a wave pattern is formed on the outer surface of the chain block 312. The pneumatic wheel 331 rolls along the surface of the chain block 312, thereby driving the swing lever 32 to swing.

[0049] The support frame 334 includes a support rod 3341 and a support plate 3342. The support rod 3341 slides along the hollow shaft 333. The support plate 3342 is installed on the support rod 3341. The support plate 3342 presses against the inner side of the air wheel 331 and fits against the inner side of the air wheel 331 to ensure the stability of the air wheel 331 when it rolls along the chain block 312.

[0050] The warp knitting process for car seat warp-knitted mesh fabric includes the following steps:

[0051] S1: The scripture delivery system delivers scriptures;

[0052] S2: The comb transverse system 3 moves transversely, causing the yarn to be padded around the weaving system 2;

[0053] S3: The transmission system 4 drives the weaving system 2 to rise and fall, causing the yarn to form loops;

[0054] S4: The air wheel 331 is inflated according to the degree of wear. The push shaft 332 rotates as the air wheel 331 expands under the drive of the torsion spring. After the air wheel 331 is inflated, the push shaft 332 pushes the support frame 334 to the outside of the air wheel 331 to maintain the outer diameter of the air wheel 331. The air wheel 331 rolls along the transverse cam device 31, and the swing lever 32 pushes the comb plate 35 to move laterally.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
