[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] For example, see Figures 1-9 , a textile warp stopping device for preventing accumulation of flying waste, comprising a support seat 1; A warp stop assembly 3 for fixed-point detection is connected to the top of the support seat 1; The warp stop assembly 3 includes a support plate 31, a bracket 311, a connecting rod 312 and a fixed-point detection assembly. The support plate 31 is fixedly mounted at both ends of the top of the support seat 1. The support plate 31 is symmetrically fixedly connected to the connecting rod 312 in the front and rear directions. The brackets 311 are fixedly mounted on the connecting rod 312 at equal intervals. The bracket 311 is connected to a fixed-point detection assembly for fixed-point detection. The warp stop piece is located above the fixed-point detection assembly. The support base 1 is also connected to a waste discharge assembly 4 for collecting flying waste; The waste discharge assembly 4 includes a transverse pipe 41, an air extraction pipe 42 and an air hole 43. A set of support plates 31 are fixedly installed with transverse pipes 41 at equal intervals. The top of the transverse pipe 41 is provided with air holes 43 at equal intervals. The top of the air hole 43 is lower than the top of the positioning detection assembly. The outer end of the transverse pipe 41 is fixedly connected to the air extraction pipe 42. A cleaning assembly 2 for cleaning the dropper pieces is fixedly connected to the rear side of the top of the support seat 1 .

[0022] The exhaust pipe 42 is connected to external high-pressure dust removal equipment.

[0023] When the drop wire detector is being tested, the external high-pressure dust removal equipment sucks the gas through the suction pipe, and the gas is sucked through the air holes to flow into the positioning detection component. The flying debris enters the horizontal pipe through the air holes, and then enters the external high-pressure dust removal equipment through the suction pipe for collection. This can prevent the accumulation of flying debris, ensure the accuracy of the drop wire detection, and avoid affecting the processing environment. At the same time, when the wire breaks, the drop wire detector falls onto the fixed-point detection component of the drop wire component 3, and the fixed-point detection component accurately positions the falling drop wire detector, which is conducive to quickly finding the wire break position. In addition, the cleaning component 2 can blow the drop wire detector to prevent the adhesion of flying debris on the drop wire detector, ensure the normal use of the drop wire detector, and avoid the influence of flying debris on the wire break detection of the drop wire detector.

[0024] The fixed-point detection component includes a box body 32, a conductive sheet 33, a conductive plate 34, a U-shaped insulating plate 35, an ammeter 36, a positive wire 37, a negative wire 38, a resistance tube 39, and an electrical contact 310. The side wall of the box body 32 is fixedly connected with U-shaped insulating plates 35 at equal intervals. The top of the U-shaped insulating plate 35 is fixedly connected with a conductive plate 34. The front and rear side walls of the U-shaped insulating plate 35 are fixedly connected with conductive sheets 33 at equal intervals. An electrical contact 310 is fixedly connected between the adjacent front and rear conductive sheets 33 of the U-shaped insulating plate 35. The electrical contact 310 is in close contact with the resistance tube 39. The resistance tube 39 is fixedly installed in the groove formed in the U-shaped insulating plate 35. The end of each resistance tube 39 is electrically connected to a negative wire 38. Each conductive plate 34 is electrically connected to the negative pole of the ammeter 36 through a wire. The positive pole of the ammeter 36 is electrically connected to a positive wire 37. The positive wire 37 and the negative wire 38 are respectively connected to the positive and negative poles of an external power supply. The ammeter 36 is installed in the box body 32. The ammeter 36 is electrically connected to an external control system. The current value detected by the ammeter 36 is transmitted to the external control system. When the voltage is constant, the smaller the current, the larger the resistance; the larger the current, the smaller the resistance. Through the resistance calculation formula, the conductive length of the resistance tube 39 can be known, so as to determine the conductive position of the resistance tube 39.

[0025] The U-shaped insulating plate 35 is inserted into the installation groove formed in the bracket 311.

[0026] The air holes 43 are located on both sides of the U-shaped insulating plate 35, and the bottom of the air holes 43 is flush with the top of the U-shaped insulating plate 35. When the wire breaks, the drop wire stop falls onto the conductive plate 34 of the fixed-point detection component, and the drop wire stop contacts the conductive sheet 33 at its falling position. The external power supply, the positive wire 37, the ammeter 36, the conductive plate 34, the drop wire stop, the conductive sheet 33 at the falling position of the drop wire stop, the electrical contact 310 connected to the conductive sheet 33 at the falling position of the drop wire stop, the resistance tube 39, and the negative wire 38 form a closed return circuit, and the conductive sheets 33 at other positions are in a non-conductive state. The ammeter 36 determines the resistance of the resistance tube 39 conducting current by detecting the magnitude of the current, and uses the principle of measuring the resistance of a sliding rheostat to detect the position of the energized conductive sheet 33. The position of the drop wire stop where the wire breaks can be accurately determined through the position of the conductive sheet 33, realizing precise positioning of the dropped drop wire stop, which is conducive to quickly finding the wire break position.

[0027] The cleaning component 2 includes a lateral movement component, a paddle 211, and an adjustable air jet component. The lateral movement component is fixedly installed at the rear end of the top of the support base 1. The lateral movement component is connected to the paddle 211 and the adjustable air jet component. The air jet end of the adjustable air jet component is located on both sides of the paddle 211. The bottom of the paddle 211 is one centimeter lower than the top of the drop wire stop in the non-wire-break state, and the air jet end of the adjustable air jet component is higher than the top of the drop wire stop in the non-wire-break state.

[0028] The lateral movement component includes a support frame 21, a linear module 22, a position sensor 25, and a connecting block 26. The front side wall of the support frame 21 is fixedly connected to the linear module 22. The driving end of the linear module 22 is fixedly connected to the connecting block 26. Position sensors 25 for the position of the connecting block 26 are fixedly connected to both the left and right ends of the linear module 22. The adjustable air jet component is connected to the connecting block 26; The adjustable air jet component includes a drag chain 23, a bridge 24, a manifold 27, an inlet pipe 28, a flow control valve 29, a mounting plate 210, and a nozzle 212. The bridge 24 is fixedly installed on the front side wall of the support frame 21. The fixed end of the drag chain 23 is fixedly connected to one end of the bridge 24. The movable end of the drag chain 23 is fixedly connected to the connecting block 26. The inlet pipe 28 is installed inside the drag chain 23. The inlet pipe 28 is fixedly connected to the input end of the flow control valve 29. Two output ends of the flow control valve 29 are fixedly connected to the manifolds 27. The manifolds 27 are fixedly connected with nozzles 212 at equal intervals at the bottom. The nozzles 212 are fixedly installed on the mounting plate 210. The mounting plate 210 is fixedly installed and connected to the paddle 211; The bridge 24 is arranged above the linear module 22; The nozzles 212 are all inclined towards the paddle 211, and the inclination angle of the nozzles 212 is thirty to sixty degrees.

[0029] The nozzles 212 of the adjustable air jet component are higher than the top of the drop wire stop in the non-wire-break state.

[0030] The inlet pipe 28 is connected to an external blower.

[0031] When the linear module 22 of the lateral moving assembly of the cleaning assembly 2 drives the connecting block 26 to move to the left, at the same time, the diverter valve 29 of the adjustable jet assembly is turned on to the nozzle 212 on the right, and the external fan draws air into the inlet pipe 28, passes through the diverter valve 29, enters the diverter pipe 27, and is sprayed out from the nozzle 212 on the right. Since the bottom of the paddle 211 is one centimeter lower than the top of the stop piece in the unbroken yarn state, the paddle 211 pushes the upper end of the stop piece to tilt to the upper left when it moves to the left, and the stop piece is facing the nozzle 212 on the right. The nozzle 212 on the right sweeps the right side wall of the inclined stop piece, and the position sensor 25 on the left detects After reaching the connecting block 26, the linear module 22 of the transverse moving assembly of the cleaning assembly 2 drives the connecting block 26 to move to the right. At the same time, the diverter valve 29 of the adjustable jet assembly is turned on to the nozzle 212 on the left. The external fan draws air into the inlet pipe 28, passes through the diverter valve 29, enters the diverter pipe 27, and is sprayed out from the nozzle 212 on the left. Since the bottom of the paddle 211 is one centimeter lower than the top of the stop piece in the unbroken yarn state, the paddle 211 pushes the upper end of the stop piece to tilt to the upper right when it moves to the right. The stop piece is facing the left side wall of the nozzle 212, and the left side wall of the left nozzle 212 blows the inclined left side wall of the stop piece.

[0032] The cleaning component 2 can be used to purge the dropper piece to prevent flying fibers from adhering to the dropper piece, thereby ensuring the normal use of the dropper piece and preventing flying fibers from affecting the broken yarn detection of the dropper piece.
