Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a sley seat structure with adjustable sley needle gap and needle seat position. Background Art

[0002] Warping machine or sizing machine is a textile machine used to wind a certain number of warp yarns in parallel on the warp beam or weaving beam according to the specified length and width. The warp yarns are wound evenly on the warp beam with a certain tension according to the number and length required by the weaving process.

[0003] During the warping process, it is necessary to ensure that the tension of each warp yarn is equal, evenly distributed on the warp beam or weaving beam, and the arrangement of the colored yarns complies with the process requirements.

[0004] During warping, factors such as yarn count, yarn path, warping speed and working status need to be considered. In addition, the spacing of the warp yarns needs to be adjusted during the warping process to adapt to the warp yarn arrangement spacing specified by the process, and the lateral adjustment of the warp yarns needs to be controlled; ensure that the telescopic reed adjustment and its lateral adjustment are appropriate. The quality of warping has a great impact on weaving production. In practice, it is found that about 70% of the defects in weaving are caused by poor warping.

Even if it rotates, it is impossible to accurately control the width, especially as the width increases and the number of sliders increases. It is even more difficult to control; secondly, the left end is a fixed block and the right end is a movable block. The screw can only control the yarn to shrink to one side to adjust the width during rotation. This can easily cause the warp yarn to be rolled up at one end of the yarn tube and unevenly distributed during warping; it is impossible to achieve telescopic adjustment relative to the center, and the adjustment effect is poor; thirdly, one end of the needle frame is fixed, and the lateral adjustment of the overall position of the needle frame cannot be achieved, resulting in limited use of the warping machine.

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] A sley seat structure with adjustable sley needle gap and needle seat position, such as Figure 1-6 As shown, it includes a mounting base 1, the upper end surface of which can be provided with a track groove for adjusting the telescopic reed chain 3; in actual use, it includes telescopic adjustment and lateral adjustment of the telescopic reed chain 3.

[0028] Specifically, Figure 2 , 6 As shown, the reed chain unit 9 is provided with a pivot shaft 7, and the lower end of the pivot shaft 7 of each reed chain unit 9 is slidably arranged in the track groove, as shown in FIG. Figure 6 As shown, the lower end of the pivot shaft 7 forms a T-shaped cross section, and its bottom is round, so that it can move along the track groove; thereby, the telescopic reed chain 3 can be arranged neatly in a straight line, and the straight line can be maintained for telescopic or lateral movement control, such as Figure 2 shown.

[0029] The telescopic reed chain 3 is slidably arranged on the mounting base 1, and the two sides of the telescopic reed chain 3 move in a mirror-image manner relative to the middle position thereof; as an embodiment of the telescopic reed chain, specifically, Figure 2 , 5 As shown in Figure 6, the telescopic reed chain 3 includes a reed hinge piece 6, a pivot shaft 7, and a hinge end 8. The midpoint of the reed hinge piece 6 is rotatably connected to the pivot shaft 7, and both ends form a hinge end 8; the midpoints of the two reed hinge pieces 6 are pivotally connected through the pivot shaft 7 to form a reed chain unit 9. Since the middle parts of the two sheet-shaped reed hinge pieces 6 are pivotally connected, the reed chain unit 9 can be made as shown in Figure 6. Figure 5 As shown in the figure, a cross shape is formed and the shape is changed. When several reed chain units 9 are connected, they form a Figure 2 The telescopic reed chain 3 shown, specifically, the hinged ends 8 between the two reed chain units 9 are hinged to each other, that is, the ends of the two reed hinge pieces 6 of the two reed chain units 9 are correspondingly hinged, and the reed needle piece is installed on the reed hinge piece 6. It can be understood that the reed needle piece is driven by the reed hinge piece 6 to rotate, so that the rotation angle of the reed needle piece is controlled, and the yarn passing through the reed needle piece can use the deflection of the reed needle piece to change the distance between each other; it can be understood that those skilled in the art can apply the above-mentioned detachable structure to the existing ordinary straight rod reed chain structure to change it into a form that can be easily disassembled.

[0030] As an improved embodiment of the telescopic reed chain, as the yarn width increases, a larger number of reed chain units 9 are provided, and there will inevitably be some rotation clearance between the axis of the rotational connection portion between the pivot shaft 7 and the hinge end 8 of the reed chain unit 9 and the reed hinge piece 6; therefore, when controlling the deformation of the telescopic reed chain 3, the deformation near the connection between the reed chain and the driving end occurs earlier, while the deformation of the reed chain unit 9 farther away from the connection with the driving end occurs later, forming a phenomenon of far-end delay, thereby causing uneven yarn distribution; in order to overcome this drawback, as an improvement, such as Figure 2 , 5 As shown in 6, the reed hinge piece 6 is a butterfly-shaped sheet structure, so that the side of the reed hinge piece 6 protrudes outward to form a convex arc-shaped side 10. The existing ordinary reed chain is an ordinary straight rod structure, and the two adjacent reed chains are not in contact with each other except the hinge end 8. In this embodiment, the side of the reed hinge piece 6 is provided with a circular arc-shaped side protruding side, thereby increasing the width of the reed hinge piece 6, and making the convex arc-shaped side 10 of the two adjacent reed chain units 9 tangentially matched, so that the sides of the two reed chain units 9 remain tangential when the reed chain units 9 perform pivoting motion. Figure 5 As shown, it is a schematic diagram of the change of two adjacent reed chain units 9 from an extended state to a contracted state. It can be seen that in the process of change, the sides of the two adjacent reed hinge pieces 6 of the upper layer are tangent to each other and the tangent contact position changes accordingly. Similarly, the two adjacent reed hinge pieces 6 of the lower layer are also tangently connected. Since the width of the reed hinge piece 6 is increased and the sides fit each other, the effect of completely covering the upper side of the profile rail 1 can be formed. The advantages are, firstly, when the telescopic reed chain 3 is deformed, the two adjacent reed chain units 9 use the relationship of tangent connection on the sides to form mutual extrusion, so that the deformation of the proximal end and the distal end can be kept consistent, avoiding uneven deformation of the telescopic reed chain 3. The butterfly piece type uses the tangent outer contour to make the reed hinge piece 6 more accurate. Secondly, since the closure is formed on the upper side of the profile rail 1, dust is not easy to fall into the driving mechanism below through the gap of the reed hinge piece 6. It can be understood that the improvement of the shape of the reed hinge piece based on the aforementioned embodiment of the detachable telescopic reed chain can be applied to a telescopic reed chain with a longer length to achieve uniform telescopic control.

[0031] The reed needle gap adjustment mechanism is arranged in the installation base 1, and controls the telescopic movement of the telescopic reed chain 3 through the belt structure 4. In actual use, the belt structure 4 includes but is not limited to a synchronous belt, a belt, a steel belt, and a chain structure. In this embodiment, a flat belt is used as an example. The belt structure 4 has two driving side edges 5, and the two driving side edges 5 are respectively connected to the two ends of the telescopic reed chain 3. Specifically, Figure 2 , 4As shown, the reed needle gap adjustment mechanism also includes an active head assembly 13, a driven head assembly 14, and a driving plate 15; the active head assembly 13 and the driven head assembly 14 are respectively arranged at both ends of the installation base 1, and a belt structure 4 is sleeved on the pulleys of the active head assembly 13 and the driven head assembly 14, and the belt structure 4 is arranged axially through the installation base 1, and a driving motor is arranged in the active head assembly 13, which drives the belt structure 4 to operate, and the pulley arranged in the driven head assembly 14 on the other side is used to limit the end of the belt structure 4, and a belt structure 4 tension adjustment device can be arranged on the driven head assembly 14 to change its tension; further, driving plates 15 are respectively arranged on the two driving side edges 5 of the belt structure 4, and a connecting rod 24 for connecting to the pivot shaft 7 is arranged on the upper side of the driving plate 15. When the driving plate 15 is driven to move the position by the belt structure 4, the telescopic reed chain 3 can be controlled to deform by the connecting rod 24 as the driving end, as shown in FIG. Figure 2 , 3 As shown, the two driving plates 15 are arranged in a central symmetrical position. Since the two driving plates 15 are respectively installed on both sides of the belt structure 4, the driving plates 15 move symmetrically. The two driving plates 15 are respectively connected to the pivot shaft 7 of the telescopic reed chain 3, thereby driving the telescopic reed chain 3 to form a mirror-image telescopic movement relative to its middle position; the installation base 1 is provided with a long waist hole 16 for the driving plate 15 to pass through and connect the pivot shaft 7, as shown in FIG. Figure 2 As shown, the connecting rod 24 passes through the long waist hole 16 upward from the installation base 1 and is connected to the pivot shaft 7 to drive the telescopic reed chain 3.

[0032] Furthermore, the reed needle gap adjustment mechanism also includes a limit detection column 17 and a limit switch 18. The belt structure 4 is provided with a limit detection column 17, and one end of the mounting base 1 is provided with a limit switch 18. The limit detection column 17 matches the limit switch 18. When the telescopic reed chain 3 is telescopically controlled, the motor in the active head assembly 13 is automatically stopped when the limit detection column 17 moves with the belt structure 4 and touches the limit switch 18. The opposite belt structure is also provided with a limit detection column 17 to prevent excessive contraction and excessive stretching.

[0033] The needle seat transverse adjustment mechanism is also included, so that the reed needle gap adjustment mechanism is slidably arranged in the installation base 1, and a driving unit is fixedly arranged at one end of the installation base 1, and the driving unit controls the axial movement position of the reed needle gap adjustment mechanism along the installation base 1. Specifically, in this embodiment, the needle seat transverse adjustment mechanism can be used as a whole and can slide in the installation base 1, such as Figure 2 , 3As shown, the sliding connection of the end vertical plates of the active head assembly 13 and the driven head assembly 14 is in the installation base 1, forming an integral sliding guide for the reed needle gap adjustment mechanism. The driving part includes a screw motor assembly 20, and the driven head assembly 14 is provided with a screw hole 21 on the side close to the screw motor assembly 20, and the screw end of the screw motor assembly 20 is screwed in the screw hole 21. In this embodiment, the active head assembly 13 and the driven head assembly 14 are not fixedly connected to the installation base 1, but form a sliding connection. The screw motor assembly 20 is fixedly set at one end of the installation base 1, and the linear motor principle is used to push or pull the movement of the reed needle gap adjustment mechanism as a whole. It can be understood that the active head assembly 13 and the driven head assembly 14 are connected and fixed by a rod-like structure, so that an overall movement can be formed to achieve the purpose of adjusting the lateral position.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
