Description

Technical Field

[0001] The utility model relates to a weft insertion mechanism for Zhang velvet satin production, belonging to the technical field of cloth processing. Background Art

[0002] Zhang satin, also known as Zhang velvet satin, is a representative work of ancient Chinese velvet fabrics. It originated in Zhangzhou, Fujian in the late Ming and early Qing dynasties. It is made of two sets of warp threads and four sets of weft threads. It innovates the original plain velvet fabric in terms of fabric structure and becomes the most artistic all-silk jacquard velvet fabric with satin as the ground and velvet warp flower structure. The craftsmanship is extremely exquisite.

[0003] A variety of weft threads are needed in the weaving process of Zhangrong satin. When multiple weft threads are fed in at the same time, the incoming weft threads will be merged into coarse weft threads with a thicker diameter. When the multiple weft threads move, since the multiple weft threads are not twisted into one thread, the multiple weft threads will move relative to each other and diverge. This will lead to poor stability when the multiple weft threads are fed in, affecting the subsequent weft weaving operations. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a weft insertion mechanism for Zhangrong satin production, which solves the problem in the prior art that when multiple weft threads are fed in, relative movement occurs between each other, resulting in divergence, which leads to poor stability when the multiple weft threads are fed in.

[0005] The cam is secured to the base and has two opposite ends, each of which is secured to a position detachable from the base and has a pivotal position about the other end of the cam, the second end of the cam being secured to the base and having a spring loaded retaining mechanism, a spring loaded retaining mechanism, a screw bolt, and a spring loaded retaining mechanism.

[0006] By adopting the above technical solution, when multiple strands of weft yarns are fed in at the same time, the multiple strands of weft yarns are independent individuals and are not twisted into one strand, thereby forming a coarse weft yarn. In the process of passing through the lead-in channel, the weft yarns will partially shake during the transmission process, causing the multiple strands of weft yarns to spread out. At this time, the scattered weft yarns will contact the limiting wheel, and the limiting wheel will restrict the scattered weft yarns to prevent the multiple strands of weft yarns from further diverging, which is beneficial to improving the stability of the multiple strands of weft yarns during the feeding process.

[0007] The utility model is further configured as follows: an annular inflation chamber is opened in the limiting wheel, the inflation chamber is provided with openings on the side facing the fixed wheel and the side facing away from the connecting sleeve, a pressure layer is fixedly provided at the opening of the inflation chamber facing the fixed wheel, an expansion layer is fixedly provided at the opening of the limiting wheel facing away from the connecting sleeve, the expansion layer is fixedly connected to the opposite end of the pressure layer, and the inflation chamber is filled with gas.

[0008] The utility model is further configured as follows: an annular fixed pressing ring is fixedly provided on the side of the fixed wheel facing the limiting wheel, and the end face of the fixed pressing ring away from the fixed wheel is arc-shaped, and the arc-shaped end face of the fixed pressing ring abuts against the pressure layer, and the elastic coefficient of the pressure layer is smaller than that of the expansion layer.

[0009] By adopting the above technical solution, after the inflation chamber is filled with gas, the limiting wheel moves axially along the rotating shaft, so that the fixed pressing ring abuts against the pressure layer, and the fixed pressing ring squeezes the pressure layer. At this time, the pressure layer is deformed by the pressure, so that the air pressure in the inflation chamber increases. At this time, the expansion layer is expanded toward the direction of the guide channel under pressure, thereby reducing the opening of the guide channel. When the opening of the guide channel is reduced, the multiple strands of weft yarn passing through can contact the expansion layer. At this time, the expansion layer limits the lateral displacement of the multiple strands of weft yarn during movement, which is conducive to further improving the stability of the movement process of the multiple strands of weft yarn.

[0010] The utility model is further configured as follows: a plurality of disorderly distributed friction layers are fixed on the outer curved surface of the friction layer.

[0011] The utility model is further configured as follows: a stop cavity is opened on the side of the limiting wheel away from the fixed wheel, a stop plate is inserted in the stop cavity, an end of the stop plate away from the limiting wheel passes through the support plate and extends to the side of the support plate away from the limiting wheel, a movable plate is fixedly provided on the end of the stop plate away from the limiting wheel, a threaded rod is threadedly connected to the movable plate, and one end of the threaded rod is rotatably connected to the support plate.

[0012] By adopting the above technical solution, by rotating the threaded rod, the movable plate slides axially along the threaded rod under the action of the threaded structure, thereby pushing the limiting wheel to move toward the fixed wheel. In this process, the pressure between the fixed pressing ring and the pressure layer can be changed, so that the air pressure value in the inflation chamber changes, thereby achieving the purpose of adjusting the expansion degree of the expansion layer. It can be adjusted according to the number and thickness of the weft yarn, greatly improving the adaptability range of the weft insertion mechanism. At the same time, the friction layer can increase the friction between the fixed wheel and the weft yarn, making the fixed wheel rotate more stably. In the process of the fixed wheel driving the fixed pressing ring to rotate and causing the pressure layer and the fixed pressing ring to slide relative to each other, the pressure layer will generate static electricity. At this time, foreign matter such as thread ends attached to the multiple weft yarns passing through the guide channel can be adsorbed by static electricity, thereby achieving the purpose of simple cleaning of the weft yarns.

[0013] The utility model is further configured as follows: a limiting plate located in the radial direction of the rotating shaft is fixedly provided on the base, a limiting hole aligned with the lead-in channel is provided on the limiting plate, the opening direction of the limiting hole is the same as the extension direction of the coarse weft thread, and a chamfer is provided on the side of the limiting hole away from the lead-in channel.

[0014] By adopting the above technical solution, the extension paths of the multiple strands of weft yarn pass through the limiting holes, and the multiple strands of weft yarn can be collected and concentrated at this time, so that the weft yarns can subsequently pass through the guide channel stably.

[0015] The beneficial effect of the present invention is that when multiple strands of weft yarns are fed in at the same time, the multiple strands of weft yarns are individually independent and are not twisted into one strand, thereby forming a coarse weft yarn. In the process of passing through the wire guide channel, the weft yarns will partially shake during the transmission process, causing the multiple strands of weft yarns to spread out. At this time, the scattered weft yarns will contact the limiting wheel, and the limiting wheel will restrict the scattered weft yarns to prevent the multiple strands of weft yarns from further diverging, which is beneficial to improving the stability of the multiple strands of weft yarns during the feeding process.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0022] like Figure 2-3 As shown, a weft insertion mechanism for Zhang velvet satin production includes a weft thread, the weft thread is provided with multiple strands, and the multiple strands of weft thread form a coarse weft thread, and also includes a base 10, a support plate 11, a fixed wheel 20, a rotating shaft 24, a connecting sleeve 25 and a limiting wheel 30. The base 10 is placed horizontally, and two support plates 11 are relatively provided. The ends of the support plates 11 are plugged into the base 10 and the support plates 11 extend vertically. The rotating shaft 24 is rotatably provided between the two support plates 11. Two rotating shafts 24 are provided in parallel in a vertical manner. The connecting sleeve 25 is sleeved on the rotating shaft 2 4 and is fixedly connected to the rotating shaft 24. The fixed wheel 20 is sleeved on the outside of the connecting sleeve 25 and is fixedly connected to the connecting sleeve 25. The limiting wheels 30 are arranged on both sides of the fixed wheel 20 along the axial direction of the rotating shaft 24. The limiting wheel 30 is sleeved on the connecting sleeve 25. The limiting wheel 30 is rotatably connected to the connecting sleeve 25 and slides along the axial direction of the rotating shaft 24. The diameter of the limiting wheel 30 is larger than that of the fixed wheel 20. The opposite sides of the fixed wheel 20 and the limiting wheel 30 located on the two rotating shafts 24 form a guide channel, and the extension path of the coarse weft thread passes through the guide channel.

[0023] like Figure 3-4As shown, an annular inflation chamber 31 is provided in the limiting wheel 30, and the inflation chamber 31 is provided with openings on the side facing the fixed wheel 20 and the side facing away from the connecting sleeve 25. A pressure layer 33 is fixedly provided at the opening of the inflation chamber 31 facing the fixed wheel 20, and an expansion layer 32 is fixedly provided at the opening of the limiting wheel 30 facing away from the connecting sleeve 25. The expansion layer 32 is fixedly connected to the opposite end of the pressure layer 33, and the inflation chamber 31 is filled with gas. An annular fixed pressing ring 22 is fixedly mounted on the side of the fixed wheel 20 facing the limiting wheel 30. The end face of the fixed pressing ring 22 facing away from the fixed wheel 20 is arc-shaped. The arc-shaped end face of the fixed pressing ring 22 abuts against the pressure layer 33. The elastic coefficient of the pressure layer 33 is smaller than that of the expansion layer 32. The pressure layer 33 is made of rubber, while the fixed pressing ring 22 can be made of glass or hard rubber. When the fixed pressing ring 22 is made of hard rubber, the elastic coefficient of the hard rubber is much smaller than that of the pressure layer 33. Therefore, when the pressure layer 33 and the fixed pressing ring 22 are pressed and abutted, the deformation of the fixed pressing ring 22 is much smaller than that of the pressure layer 33. A plurality of randomly distributed friction layers 21 are fixed to the outer curved surface of the friction layer 21.

[0024] like Figure 2-3 As shown, a stop cavity 34 is opened on the side of the limiting wheel 30 away from the fixed wheel 20, and a stop plate 15 is inserted into the stop cavity 34. The end of the stop plate 15 away from the limiting wheel 30 passes through the support plate 11 and extends to the side of the support plate 11 away from the limiting wheel 30. A movable plate 14 is fixedly provided on the end of the stop plate 15 away from the limiting wheel 30. A threaded rod 16 is threadedly connected to the movable plate 14, and one end of the threaded rod 16 is rotatably connected to the support plate 11.

[0025] like Figure 1 As shown, a retaining plate 12 is fixedly mounted on the base 10, radially aligned with the rotation axis 24. Retaining holes 13 are defined in this retaining plate, aligned with the thread guide channel. The opening of retaining holes 13 aligns with the direction in which the rough weft threads extend, and the side of retaining holes 13 facing away from the thread guide channel is chamfered. Multiple strands of weft threads extend through retaining holes 13, allowing them to be collected and concentrated, facilitating their subsequent stable passage through the thread guide channel.

[0026] When multiple strands of weft yarns are fed in at the same time, the multiple strands of weft yarns are independent and are not twisted into one strand, thus forming a coarse weft yarn. In the process of passing through the wire guide channel, the weft yarns will partially shake during the transmission process, causing the multiple strands of weft yarns to spread out. At this time, the scattered weft yarns will contact the limiting wheel 30. At this time, the limiting wheel 30 restricts the scattered weft yarns to prevent the multiple strands of weft yarns from further diverging, which is beneficial to improving the stability of the multiple strands of weft yarns during the feeding process.

[0027] When the inflation chamber 31 is filled with gas, the limiting wheel 30 moves axially along the rotating shaft 24, so that the fixed pressing ring 22 abuts against the pressure layer 33. At this time, an adsorption gap 23 is formed between the fixed pressing ring 22 and the pressure layer 33, and the fixed pressing ring 22 squeezes the pressure layer 33. At this time, the pressure layer 33 is deformed by the pressure, so that the air pressure in the inflation chamber 31 increases. At this time, the expansion layer 32 is expanded toward the direction of the guide channel under pressure, thereby reducing the opening of the guide channel. When the opening of the guide channel is reduced, the multiple strands of weft yarn passing through can contact the expansion layer 32. At this time, the expansion layer 32 limits the lateral displacement of the multiple strands of weft yarn during movement, which is beneficial to further improve the stability of the movement process of the multiple strands of weft yarn.

[0028] By rotating the threaded rod 16, under the action of the threaded structure, the movable plate 14 slides axially along the threaded rod 16, thereby pushing the limiting wheel 30 to move toward the fixed wheel 20. In this process, the pressure between the fixed pressing ring 22 and the pressure layer 33 can be changed, so that the air pressure value in the inflation chamber 31 changes, thereby achieving the purpose of adjusting the expansion degree of the expansion layer 32. It can be adjusted according to the number and thickness of the weft yarn, greatly improving the adaptability range of the weft insertion mechanism. At the same time, the friction layer 21 can increase the friction between the fixed wheel 20 and the weft yarn, making the rotation of the fixed wheel 20 more stable. In the process of relative sliding friction between the pressure layer 33 and the fixed pressing ring 22 driven by the fixed wheel 20, static electricity will be generated in the pressure layer 33. At this time, foreign matter such as thread ends attached to the multiple strands of weft yarn passing through the guide channel can be electrostatically adsorbed into the adsorption gap 23, thereby achieving the purpose of simple cleaning of the weft yarn, and at the same time, it can also prevent the adsorbed thread ends from interfering with the moving multiple strands of weft yarn. Then, the limiting wheel 30 can be disassembled by moving the limiting wheel 30 axially away from the fixed wheel 20 along the rotating shaft 24. At this time, the thread ends on the surface of the pressure layer 33 can be cleaned, and the operation is convenient.

Those skilled in the art will appreciate that the present invention is not limited to the above embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such modifications and improvements fall within the scope of protection claimed by the present invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
