Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery, and more specifically relates to a warp stopping device for weaving metal fiber antistatic grey cloth. Background Art

[0002] For textile machinery, whether it is a shuttle loom or a shuttleless loom, the basic principle is to interweave yarns into cloth through warp and weft. In order to detect warp breakage in time during the weaving process and realize automatic shutdown, warp breakage detection is usually carried out by combining warp drop bars and drop plates. When the warp yarn passing through the drop plate breaks, the drop plate falls on the drop bar, causing the conductive parts between the drop plate and the drop bar to contact and trigger an electrical signal. The electrical signal is fed back to the controller to control the equipment to automatically shut down.

[0003] There is an automatic warp break detection device, whose application number is CN201720705165.8. The warp drop bar in the device includes an inner electrode, an outer electrode and an insulating layer. When the warp yarn breaks, the warp drop bar falls due to gravity, so that the inner electrode and the outer electrode of the warp drop bar are connected. When the loom is weaving a grey cloth containing metal fibers, due to the strong conductivity of metal fibers, the flying fuzz generated by the metal fibers will contact the inner and outer electrodes of the warp drop bar, causing the loom to be powered on and stop for no reason. Utility Model Content

[0004] The utility model aims to provide a warp stop device for weaving metal fiber antistatic grey cloth, aiming to solve the problem that when the existing loom is weaving grey cloth containing metal fibers, the flying fuzz generated by the metal fibers contacts the inner electrode and the outer electrode of the warp stop bar, causing the loom to be electrified and stop for no reason.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a warp stop device for woven metal fiber antistatic grey cloth, comprising: a base, the tops of both ends of which are provided with support columns in the horizontal direction;

[0006] A warp stop plate is fixedly mounted on the top of the two support columns; the warp stop plate comprises a warp stop bar and an insulating layer, wherein the insulating layer wraps the outer side wall and the bottom of the warp stop bar;

[0007] A warp stop bar, fixedly installed just below the warp stop plate; and

[0008] A drop plate, wherein a sliding groove for the drop plate to pass through is provided in the middle thereof;

[0009] When the warp yarn passing through the dropper is broken, the dropper falls downward, thereby connecting the dropper bar and the dropper rod.

[0010] In a possible implementation manner, the warp stop plate and the warp stop bar are fixed via a connecting rod.

[0011] In a possible implementation, there are two connecting rods, which are respectively located at two ends of the warp stop bar in the length direction.

[0012] In a possible implementation, the connecting rod is made of insulating material.

[0013] In a possible implementation, the connecting rod is respectively connected to the warp drop bar and the warp drop bar through threads.

[0014] In a possible implementation, a hook is provided at the upper end of the connecting rod, and a slot matching the hook is provided at the top of the drop bar.

[0015] In one possible implementation, the connecting rod includes a first cylindrical rod, a second cylindrical rod and a locking piece; the upper end of the first cylindrical rod is fixedly connected to the warp stop bar, the lower end of the second cylindrical rod is fixedly connected to the warp stop bar, the lower end surface of the first cylindrical rod is provided with a guide groove that slides with the second cylindrical rod, the guide groove is arranged along the axial direction of the first cylindrical rod, and the locking piece is used to fix the first cylindrical rod and the second cylindrical rod.

[0016] In a possible implementation manner, the locking member is a top screw.

[0017] In a possible implementation, a ball bearing is provided on the outer circumference of the second cylindrical rod, and the second cylindrical rod is slidably engaged with the guide groove through the ball bearing.

[0018] In a possible implementation, a slot matching the lower end of the dropper piece is formed on the top of the dropper bar.

[0019] The scheme shown in the embodiment of the present application is compared with the prior art. The utility model is a warp stop device for woven metal fiber antistatic grey cloth, in which the warp stop bar and the warp stop rod are both conductors, and are respectively connected to the two poles of the circuit through guides. The insulating layer wraps the outer wall and the bottom of the warp stop bar, so only the top of the warp stop bar is exposed. Since the warp stop plate is inserted into the sliding groove, the warp stop plate can move up and down relative to the warp stop plate. When the warp yarn passing through the warp stop plate breaks, the warp stop plate will fall downward, and eventually the warp stop plate will contact the top of the warp stop bar, and the lower end of the warp stop plate will contact the warp stop rod, thereby realizing the conduction of the circuit. Since the warp stop bar and the warp stop rod of the present application are arranged vertically up and down, and there is a certain height difference between the two, and the flying fuzz generated by the metal fiber is limited in length, it will not fall on the warp stop bar and the warp stop rod at the same time, thereby avoiding the phenomenon of stopping without reason.

DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] See also Figure 1, a warp-stop device for woven metal fiber antistatic grey fabric provided by the utility model is now described. The warp-stop device for woven metal fiber antistatic grey fabric comprises: a base 1, a warp-stop plate, a warp-stop rod 3 and a warp-stop sheet 4. Support columns 101 are provided on the top of both ends of the base 1 in the horizontal direction; the warp-stop plate is fixedly installed on the top of the two support columns 101; the warp-stop plate comprises a warp-stop bar 201 and an insulating layer 202, and the insulating layer 202 wraps the outer wall and the bottom of the warp-stop bar 201; the warp-stop rod 3 is fixedly installed directly below the warp-stop plate; a sliding groove 401 for the warp-stop plate to pass through is provided in the middle of the warp-stop sheet 4; when the warp yarn passing through the warp-stop sheet 4 is broken, the warp-stop sheet 4 falls downward, thereby connecting the warp-stop bar 201 and the warp-stop rod 3.

[0029] The present embodiment provides a warp stop device for woven metal fiber antistatic grey cloth. Compared with the prior art, the warp stop bar 201 and the warp stop rod 3 are both conductors, which are respectively connected to the two poles of the circuit through guides. The insulating layer 202 wraps the outer wall and the bottom of the warp stop bar 201, so only the top of the warp stop bar 201 is exposed. Since the warp stop plate is arranged in the sliding groove 401, the warp stop plate 4 can move up and down relative to the warp stop plate. When the warp yarn passing through the warp stop plate 4 is broken, the warp stop plate 4 will fall downward, and finally the warp stop plate 4 will contact the top of the warp stop bar 201, and the lower end of the warp stop plate 4 will contact the warp stop rod 3, thereby realizing the conduction of the circuit. Since the warp stop bar 201 and the warp stop rod 3 of the present application are arranged vertically up and down, and there is a certain height difference between the two, and the flying fuzz generated by the metal fiber is limited in length, it will not fall on the warp stop bar 201 and the warp stop rod 3 at the same time, thereby avoiding the phenomenon of stopping without reason.

[0030] By providing the insulating layer 202 on the outer side of the drop bar 201, the wear of the side surface of the drop bar 201 caused by the drop bar 4 during the up and down movement is eliminated.

[0031] In some embodiments, see Figure 1 The warp stop plate and the warp stop bar 3 are fixed by a connecting rod 5. In this embodiment, the connecting rod 5 is arranged along the vertical direction. The warp stop bar 3 can maintain relative stability with the warp stop plate through the connecting rod 5.

[0032] In some embodiments, see Figure 1 , there are two connecting rods 5, which are respectively located at the two ends of the length direction of the warp stop bar 3. In this embodiment, the two connecting rods 5 are respectively located at the two ends of the length direction of the warp stop bar 3. The warp drop plate 4 is located between the two connecting rods 5. The connecting rod 5 will not affect the normal operation of the warp drop plate 4. The two connecting rods 5 support the warp stop bar 3, thereby ensuring the force balance of the warp stop bar 3 and the firmness between the warp stop bar 3 and the warp drop plate.

[0033] In some embodiments, the connecting rod 5 is made of insulating material. In this embodiment, the connecting rod 5 is made of ethylene propylene rubber. Ethylene propylene rubber is synthesized with ethylene and propylene as main raw materials, and has outstanding aging resistance, electrical insulation performance and ozone resistance.

[0034] In some embodiments, see Figure 2 , the connecting rod 5 is respectively connected to the warp stop bar 201 and the warp stop bar 3 by threads. In this embodiment, the upper and lower ends of the connecting rod 5 are provided with external threads, and the warp stop bar 201 and the warp stop bar 3 are both provided with threaded holes matching the connecting rod 5. The connecting rod 5 is installed in a threaded connection manner, which is convenient for disassembly.

[0035] In some embodiments, see Figure 5 , a hook 501 is provided at the upper end of the connecting rod 5, and a slot 203 matching the hook 501 is provided at the top of the warp drop bar 201. In this embodiment, the hook 501 and the connecting rod 5 are integrally processed by an injection molding process. The hook 501 is located at the upper end of the connecting rod 5. A slot 203 matching the hook 501 is provided on the top surface of the warp drop bar 201. The slot 203 can limit the horizontal displacement of the hook 501 relative to the warp drop bar 201.

[0036] In some embodiments, see Figure 3 , the connecting rod 5 includes a first cylindrical rod 502, a second cylindrical rod 503 and a locking member 504; the upper end of the first cylindrical rod 502 is fixedly connected to the warp stop bar 201, the lower end of the second cylindrical rod 503 is fixedly connected to the warp stop bar 3, the lower end surface of the first cylindrical rod 502 is provided with a guide groove 505 that is slidably matched with the second cylindrical rod 503, the guide groove 505 is arranged along the axial direction of the first cylindrical rod 502, and the locking member 504 is used to fix the first cylindrical rod 502 and the second cylindrical rod 503. In this embodiment, the connecting rod 5 is a split structure. The first cylindrical rod 502 and the second cylindrical rod 503 are both arranged in the vertical direction and remain coaxial. The upper end of the first cylindrical rod 502 is fixedly connected to the warp stop bar 201, and the lower end of the second cylindrical rod 503 is fixedly connected to the warp stop bar 3. The upper end of the second cylindrical rod 503 is located in the guide slot 505, and the inner diameter of the guide slot 505 is the same as the outer diameter of the second cylindrical rod 503. The second cylindrical rod 503 can move up and down relative to the first cylindrical rod 502, and the height of the warp stop rod 3 can be adjusted by changing the length of the connecting rod 5. When the position of the second cylindrical rod 503 is adjusted to the right position, the second cylindrical rod 503 and the first cylindrical rod 502 are locked and fixed by the locking member 504.

[0037] In some embodiments, see Figure 3 The locking member 504 is a jackscrew. In this embodiment, a threaded hole for installing the jackscrew is provided on the outer side wall of the first cylindrical rod 502.

[0038] In some embodiments, see Figure 4 , a ball 506 is provided on the outer circumference of the second cylindrical rod 503, and the second cylindrical rod 503 slides with the guide groove 505 through the ball 506. In this embodiment, there are multiple balls 506, which are evenly arranged along the circumference of the second cylindrical rod 503. The ball 506 converts the sliding friction between the second cylindrical rod 503 and the first cylindrical rod 502 into rolling friction, thereby reducing the friction resistance between the second cylindrical rod 503 and the first cylindrical rod 502, making it easier to adjust the height of the warp stop bar 3.

[0039] In some embodiments, see Figure 1 and Figure 5 , a slot 301 matching the lower end of the dropper piece 4 is provided at the top of the dropper bar 3. In this embodiment, each dropper piece 4 corresponds to one slot 301. When the dropper piece 4 falls onto the dropper bar 201, the lower end of the dropper piece 4 is just inserted into the slot 301 and contacts the two side walls of the slot 301, thereby increasing the contact area between the dropper piece 4 and the dropper bar 3, ensuring that the circuit can be effectively turned on.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
