Description

Technical Field

[0001] The present invention relates to the field of textile technology, in particular to a jacquard dobby textile device. Background Art

[0002] Both jacquard machines and dobby machines are used to make textile fabrics. The difference between them is that jacquard machines can make patterned fabrics but cannot make high-density products, while dobby machines are used to make ordinary fabrics but can make high-density varieties.

[0003] In existing technology, the base fabric is sometimes produced using a dobby loom, while the patterned fabric is produced using a jacquard loom. However, for high-density double-layer, direct-filled fleece, for example, the jacquard loom exceeds its performance limits and cannot be produced by conventional jacquard looms. Existing dobbies typically have 16 blades, while jacquard looms typically have 16 patterning knives. Using these two together creates a large footprint and makes coordination difficult, impacting speed and efficiency. Furthermore, the dobby and jacquard loom each have separate electronic control systems, which can easily lead to coordination issues and production scrap. Summary of the Invention

[0004] Based on this, it is necessary to propose a jacquard multi-arm integrated textile equipment that can produce both jacquard and high warp density varieties.

[0005] A jacquard dobby textile device comprises: a dobby machine, the dobby machine comprising a plurality of lifting blades arranged along the X direction in a horizontal plane, and a plurality of heald frames arranged along the Y direction in the horizontal plane, the lifting blades being arranged in a one-to-one correspondence with the heald frames and connected via a transmission assembly, the lifting blades being used to lift the heald frames along the Z direction, the heald frames being used to draw up a portion of the warp threads in the Z direction, and the plurality of lifting blades being provided with a protective beam on one side in the X direction; a jacquard machine comprising a plurality of jacquard knives arranged along the X direction in a horizontal plane, and a lifting assembly, the jacquard knives drawing up the remaining warp threads in the Z direction via the lifting assembly, and the plurality of lifting assemblies being passed between the lifting blades and the protective beam in the X direction.

[0006] In some embodiments, the number of the jacquard blades is 10; the number of the jacquard knives is 6.

[0007] In some embodiments, a warp conveying device is further included for conveying the warp along the X direction; in the Z direction, the blade and the jacquard knife are located above the warp conveying device; the multi-arm machine is arranged on the ground in the workshop, and the jacquard knife is arranged on a high-altitude platform in the workshop.

[0008] In some embodiments, the blade lifting device is configured to be able to swing in a vertical plane, and the transmission assembly includes a first rotating assembly and a second rotating assembly. The first rotating assembly and the second rotating assembly are respectively connected to the two ends of the heald frame in the Y direction. The first rotating assembly and the second rotating assembly are connected by a first connecting rod, and the first rotating assembly is pivotally connected to the blade lifting device.

[0009] In some embodiments, multiple lifting assemblies are arranged along the X direction, and each of the lifting assemblies includes multiple electromagnetic control components arranged along the Y direction. Each electromagnetic control component is connected to multiple lifting ropes, and the lifting ropes are used to draw up the warp threads. The lifting ropes are connected to hooks. The jacquard knife is configured to swing so as to hook the hooks and then lift or lower the lifting ropes. The electromagnetic control component is used to absorb the hooks when the lifting ropes rise to maintain the position of the lifting ropes.

[0010] In some embodiments, the jacquard multi-arm textile equipment further includes a crossbeam whose length direction extends along the Y direction, and a plurality of wire guide holes are provided on the crossbeam, and the plurality of lifting ropes are passed through the wire guide holes in a one-to-one correspondence.

[0011] In some embodiments, six rows of electromagnetic control components are provided in the X direction; in the Y direction, each row of electromagnetic control components includes 32 electromagnetic control components; and the crossbeam is provided with eight wire guide holes corresponding to each electromagnetic control component.

[0012] In some embodiments, the guide wire holes are arranged in multiple rows and columns, and in the X direction, adjacent guide wire holes are staggered.

[0013] In some embodiments, in the X direction, the width of the beam is 5.5 centimeters.

[0014] In some embodiments, the jacquard multi-arm textile equipment further includes a control system, and the control system is used to control the multi-arm machine and the jacquard machine to work in coordination.

[0015] In the present application, in the Z direction, the jacquard knife of the jacquard machine is arranged above the dobby machine. The lifting assembly extends in the Z direction, and the lifting assembly is passed between the lifting blade and the protective beam. In specific implementation, the dobby machine, the warp conveying equipment, and the weft conveying equipment are placed on the ground in the workshop, while the jacquard knife and its driving part are located on a high-altitude platform in the workshop. In this way, the lifting assembly hangs down in the Z direction and passes between the lifting blade and the protective beam.

[0029] As described in the background art, in the prior art, it is difficult to integrate the dobby machine and the jacquard machine while ensuring a small floor space, which makes it difficult to comprehensively utilize the respective advantages of the dobby machine and the jacquard machine.

[0030] In response to the above problems, the present application proposes a jacquard multi-arm integrated textile equipment, which integrates a dobby machine and a jacquard machine, corrects the two shortcomings of the jacquard machine that it cannot produce high warp density and the dobby machine cannot make jacquards, and combines the two advantages of the jacquard machine that can make patterns and the dobby machine that can make high warp density together to assemble the current jacquard multi-arm integrated machine.

[0031] refer to Figures 1 to 3 A jacquard dobby textile machine 100 according to one embodiment of the present application includes a dobby 10 and a jacquard machine 20. The dobby 10 includes a plurality of lifting blades 110 arranged in the X-direction in a horizontal plane and a plurality of heald frames 120 arranged in the Y-direction in a horizontal plane. The lifting blades 110 and the heald frames 120 are arranged in a one-to-one correspondence and connected by a transmission assembly 102. The lifting blades 110 are used to lift the heald frames 120 in the Z-direction. The heald frames 120 are responsible for drawing up a portion of the warp threads in the Z-direction. The plurality of lifting blades 110 are provided with a protective beam 130 on one side in the X-direction. The jacquard machine 20 includes a plurality of jacquard knives 210 arranged in the X-direction in a horizontal plane and a lifting assembly 220. The jacquard knives 210 draw up the remaining warp threads in the Z-direction via the lifting assembly 220. In the X-direction, the plurality of lifting assemblies 220 are interposed between the lifting blades 110 and the protective beam 130.

[0032] The jacquard dobby textile machine 100 also includes a warp conveyor 30 for conveying warp threads in the X-direction. The X-direction represents the direction in which the warp threads are fed. In the figure, the X-direction is perpendicular to the drawing plane and extends inward. The jacquard dobby textile machine 100 also includes a weft conveyor (not shown) for conveying weft threads in the Y-direction. In the Z-direction, the weft blade 110 and the jacquard knife 210 are located above the warp conveyor 30.

[0033] refer to Figures 1 to 3 Each lifting blade 110 of the dobby machine 10 controls a heald frame 120. Each heald frame 120 is used together to control the raising of a portion of the warp threads. Figure 3 As shown, the plurality of lifting blades 110 are arranged along the X direction. The plurality of jacquard knives 210 of the jacquard machine 20 control the remaining warp threads to be drawn up through their corresponding lifting assemblies 220. The plurality of jacquard knives 210 are also arranged along the X direction and are located on one side of the jacquard knives 210.

[0034] In the present application, in the Z direction, the jacquard knife 210 of the jacquard machine 20 is arranged above the dobby machine 10. The lifting assembly 220 extends in the Z direction, and the lifting assembly 220 is passed between the lifting blade 110 and the protective beam 130. In specific implementation, the dobby machine 10, the warp conveying equipment 30, and the weft conveying equipment are placed on the ground in the workshop, while the jacquard knife 210 of the jacquard machine 20 and its driving part are located on the high-altitude platform in the workshop. In this way, the lifting assembly 220 hangs down in the Z direction and passes between the lifting blade 110 and the protective beam 130. With this design, the lifting assembly 220 passes through the dobby machine 10, which is equivalent to being installed in the dobby machine 10, so that the size in the X direction is not increased, which is beneficial to improving the speed and efficiency of the textile equipment.

[0035] In the present application, space is made for the lifting assembly 220 by eliminating some of the lifting blades 110. Specifically, in this embodiment, the number of lifting blades 110 of the dobby machine 10 is 10; the number of jacquard knives 210 of the jacquard machine 20 is 6. In a specific implementation, only the middle 6 of the 16 jacquard knives 210 in the jacquard machine 20 can be retained. Compared with the prior art in which the number of lifting blades 110 of the dobby machine 10 and the number of jacquard knives 210 of the jacquard machine 20 are 16 each, this embodiment reduces 6 lifting blades 110 and 10 jacquard knives 210. In this way, the lifting assembly 220 of the jacquard machine 20 can be installed in the space saved after the 6 lifting blades 110 in the dobby machine 10 are eliminated, thereby ensuring that the size of the dobby machine 10 in the X direction remains unchanged.

[0036] refer to Figure 2 In this embodiment, the blade lifting device 110 is configured to be able to swing in a vertical plane. The transmission assembly 102 includes a first rotary assembly 140 and a second rotary assembly 150. The first rotary assembly 140 and the second rotary assembly 150 are respectively connected to the two ends of the heald frame 120 in the Y direction. The first rotary assembly 140 and the second rotary assembly 150 are connected by a connecting rod. The first rotary assembly 140 is connected to the blade lifting device 110.

[0037] The blade lifter 110 is driven by the power mechanism of the dobby 10 to swing vertically. As the blade lifter 110 swings, it drives the first rotary assembly 140, which in turn drives the second rotary assembly 150 via the first connecting rod 160. Together, the first and second rotary assemblies 140, 150, drive the heald frame 120 up and down.

[0038] Specifically, the first rotating assembly 140 includes a first rotating member 141 and a first lifting member 142. The second rotating assembly 150 includes a second rotating member 151 and a second lifting member 152. The first rotating member 141 is pivotally connected to the blade lifting 110, the housing 101 of the multi-arm machine 10, and one end of the first connecting rod 160, respectively. The first rotating member 141 is also pivotally connected to the first lifting member 142. The first rotating member 141 is rotationally connected to the blade lifting 110 through the second connecting rod 170. The blade lifting 110 is rotationally connected to the housing 101 of the multi-arm machine 10. The first lifting member 142 is slidingly connected to the housing 101 of the multi-arm machine 10 in the Z direction, and the first lifting member 142 is connected to one end of the heald frame 120. The second rotating member 151 is pivotally connected to the other end of the first connecting rod 160, and is also pivotally connected to the second lifting member 152. The second lifting member is slidably connected to the housing 101 of the dobby machine 10 in the Z direction, and the second lifting member is connected to the other end of the heald frame 120 .

[0039] refer to Figure 3 and Figure 4 Multiple lifting assemblies 220 are arranged along the X direction. Each lifting assembly 220 includes multiple electromagnetic control components 221 arranged along the Y direction. Each electromagnetic control component 221 is connected to multiple lifting ropes 222. The lifting ropes 222 are used to draw up the warp threads. The lifting ropes 222 are connected to hooks 223. The jacquard knife 210 is configured to swing to hook a row of hooks 223 and raise or lower the lifting ropes 222. The electromagnetic control components 221 are used to attract the hooks 223 when the lifting ropes 222 rise, thereby maintaining the position of the lifting ropes 222.

[0040] The electromagnetic control component 221 includes an electromagnet, which generates a magnetic attraction force by switching the current on and off. When the jacquard knife 210 swings and hooks the hook portion 223, the jacquard knife 210 lifts the hook portion 223 and the lifting rope 222 in the Z direction, thereby completing the warp drawing. When the hook portion 223 is lifted to a predetermined height, it can be attracted by the electromagnet and maintained in position. At this time, when the jacquard knife 210 swings in the opposite direction, it does not affect the lifting of the hook portion 223 and the lifting rope 222 to a high position. When the harness needs to be dropped, the electromagnet loses its attraction force, and the hook portion 223 and the lifting rope 222 fall under the action of gravity. When the jacquard knife 210 swings back and forth, it cooperates with the operation of the electromagnetic control component 221 to continuously lift or adjust the lifting rope 222, thereby completing the drawing and dropping of the harness.

[0041] In this embodiment, the lifting assembly 220 is positioned between the lifting blade 110 and the protective beam 130 in the X direction, thereby reducing the combined width of the lifting and heald frames 120 in the X direction. Verification has shown that the combined width of the lifting rope 222 and the heald frames 120 in this embodiment can be reduced to 25 cm, and the lifting rope 222 extends vertically, without compromising machine efficiency or speed. In contrast, in the prior art, the lifting rope 222 is at least 31 cm, and the overall faucet of the jacquard loom 20 is positioned further back, increasing the tilt angle of the lifting rope 222 and causing increased wear, which in turn affects machine efficiency and speed.

[0042] refer to Figure 1 and Figure 5 The jacquard dobby weaving machine 100 further includes a crossbeam 230 extending in the Y direction. The crossbeam 230 is provided with a plurality of wire guide holes 231, through which the plurality of lifting ropes 222 are respectively passed. The crossbeam 230 and the wire guide holes 231 thereon are used to guide the lifting. The crossbeam 230 is specifically located above the dobby 10.

[0043] The wire guide holes 231 are arranged in multiple rows and columns, with adjacent wire guide holes 231 staggered in the X direction. This allows the wire guide holes 231 to be arranged more closely in the X direction. Thus, while maintaining the same number of lifting ropes 222, more electromagnetic control components 221 can be installed in the Y direction, thereby reducing the number of rows of electromagnetic control components 221 in the X direction.

[0044] In this embodiment, six rows of electromagnetic control components 221 are provided in the X direction; each row of electromagnetic control components 221 includes 32 electromagnetic control components 221 in the Y direction; and the crossbeam 230 is provided with eight wire guide holes 231 corresponding to each electromagnetic control component 221 .

[0045] In addition, by staggering two adjacent wire guide holes 231 in the X direction, the width of the beam 230 in the X direction can be reduced. In this embodiment, the width of the beam 230 is 5.5 cm, which is much smaller than the 12 cm of the prior art.

[0046] In this embodiment, the jacquard dobby textile machine 100 further includes a control system (not shown), which is used to control the dobby machine 10 and the jacquard machine 20 to work in coordination.

[0047] Specifically, the driving commands of the dobby machine 10 and the jacquard machine 20 are compiled into the same program, which is then made into an instruction file and input into a computer to control machine production, so that the cloth produced is completely consistent with the actual pattern drawing.

[0048] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
