Description

Technical Field

[0001] The invention relates to the technical field of warp breakage processing, and more specifically to an automatic warp breakage detection device for an air jet loom. Background Art

[0002] In the textile industry, the operation of looms is crucial to the quality and production efficiency of textiles. However, warp yarn breakage often occurs during the operation of the loom, which not only affects the quality of the fabric, but also may lead to production interruptions and material waste.

[0003] In order to ensure that the loom can stop immediately after the warp breaks and avoid fabric defects, a warp break stop device must be used. At present, the most commonly used warp break stop device on air jet and rapier looms is the warp stop plate type, which uses electrical principles to collect warp break signals and is usually called a warp stop frame.

[0004] However, the existing warp-break automatic stop device with a warp dropper can only serve as a prompt when the thread is broken, and cannot accurately tell the specific location of the broken thread. In the textile process, the number of warp yarns is huge, and the number of droppers is the same. Therefore, the operator needs to find the broken thread among a large number of warp yarns and droppers, so the operating efficiency cannot be further improved, affecting the continuity of fabric production.

[0005] Therefore, it is necessary to propose a new solution to solve the above problems. Summary of the invention

[0006] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide an automatic warp break detection device for an air jet loom.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0009] Furthermore, a first solenoid valve is installed on the inner wall on the other side of the frame, and the first solenoid valve includes an air inlet connector A, an air outlet connector A and an air outlet connector B. The air inlet connector A is connected to the first air inlet pipe, the air outlet connector A is connected to the first air source interface of the cylinder through a hose, and the air outlet connector B is connected to the second air source interface of the cylinder through a hose.

[0010] Furthermore, a second solenoid valve is installed on the inner wall on the other side of the frame, and the second solenoid valve includes an air inlet connector B and an air outlet connector C. The air inlet connector B is connected to a second air inlet pipe, and the air outlet connector C is connected to the air inlet of the suction nozzle through a hose.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0023] Embodiment: An automatic warp-breaking device for an air jet loom, such as Figure 1-Figure 5 As shown, it includes a guide rail bracket 5 installed on the left wall panel 1 and the right wall panel 2, and a transmission screw 6 is provided above the guide rail bracket 5. One end of the transmission screw 6 is connected to the transmission shaft of the reduction motor 7, and the reduction motor 7 can directly drive the transmission screw 6 to rotate.

[0024] Specifically, Figure 1 , Figure 2 As shown, a left support seat 3 is fixedly mounted on the left wall panel 1, a right support seat 4 is fixedly mounted on the right wall panel 2, a guide rail bracket 5 is located between the left support seat 3 and the right support seat 4, and the two ends of the guide rail bracket 5 are respectively fixedly connected to the left support seat 3 and the right support seat 4, the two ends of the transmission screw 6 are respectively rotatably connected to the left support seat 3 and the right support seat 4, the reduction motor 7 is fixedly mounted on the left support seat 3, and the transmission shaft of the reduction motor 7 is connected to one end of the transmission screw 6 through a coupling. Among them, sliding bearings are installed on the left support seat 3 and the right support seat 4, and the two ends of the transmission screw 6 are respectively connected to two sliding bearings, so that the transmission screw 6 can rotate relative to the left support seat 3 and the right support seat 4.

[0025] Furthermore, the transmission screw 6 is threadedly connected to the transmission seat 8, and the lower surface of the transmission seat 8 abuts against the upper surface of the guide rail bracket 5; when the transmission screw 6 rotates, the transmission seat 8 moves along the length direction of the transmission screw 6. At the same time, since the lower surface of the transmission seat 8 abuts against the upper surface of the guide rail bracket 5, when the transmission seat 8 slides on the upper surface of the guide rail bracket 5, it does not rotate with the transmission screw 6.

[0026] A frame 9 is installed on the upper surface of the transmission seat 8. The frame 9 is a U-shaped structure and has an inner cavity. A first rotating shaft 10 is provided in the inner cavity of the frame 9. Both ends of the first rotating shaft 10 are rotatably connected to both sides of the frame 9, that is, sliding bearings are installed on both sides of the frame 9, and the two ends of the first rotating shaft 10 are respectively connected to two sliding bearings, so that the first rotating shaft 10 can rotate relative to both sides of the frame 9.

[0027] A suction nozzle 11 for sucking the broken warp yarn 21 is installed on the first rotating shaft 10. When the first rotating shaft 10 rotates, it can synchronously drive the suction nozzle 11 to rotate in the same direction, so that the suction port 1101 of the suction nozzle 11 rotates to the position of the broken warp yarn 21, and the broken warp yarn 21 is sucked into the suction nozzle 11.

[0028] Furthermore, one end of the first rotating shaft 10 passes through one side of the frame 9 and extends outside the frame 9, and a main gear 12 is installed thereon. A cylinder 13 is hinged on the outer wall of one side of the frame 9, and a spherical bearing 14 is installed on the piston rod of the cylinder 13. A second rotating shaft 15 is rotatably connected to the outer wall of one side of the frame 9 corresponding to the position of the main gear 12. A fan gear 16 is installed on the second rotating shaft 15, and the fan gear 16 meshes with the main gear 12. A rocker arm 17 is installed on the second rotating shaft 15, and the rocker arm 17 is connected to the spherical bearing 14.

[0029] When in use, the cylinder 13 drives the rocker arm 17 to rotate through the joint bearing 14, and the rotation of the rocker arm 17 drives the second rotating shaft 15 to rotate, and rotates through the fan gear 16. The fan gear 16 engages with the main gear 12 and drives the main gear 12 to rotate. The rotation of the main gear 12 synchronously drives the first rotating shaft 10 to rotate, and drives the suction nozzle 11 to rotate through the first rotating shaft 10.

[0030] Further, such as Figure 3 , Figure 4 As shown, a first solenoid valve 18 is installed on the inner wall on the other side of the frame 9. The first solenoid valve 18 includes an air inlet connector A1801, an air outlet connector A1802 and an air outlet connector B1803. The air inlet connector A1801 is connected to the first air inlet pipe, the air outlet connector A1802 is connected to the first air source interface 1301 of the cylinder 13 through a hose, and the air outlet connector B1803 is connected to the second air source interface 1302 of the cylinder 13 through a hose.

[0031] When air is injected from the first air inlet pipe and flows out from the air outlet connector A1802, the air flow enters the cylinder 13 along the hose through the first air source interface 1301, pushing the piston in the cylinder 13 to move, extending the piston rod of the cylinder 13 outward, and driving the fan gear 16 to rotate counterclockwise, causing the main gear 12 to rotate clockwise, thereby causing the suction nozzle 11 to rotate clockwise to the position where the warp yarn 21 is broken, and the broken warp yarn 21 is sucked into the suction nozzle 11.

[0032] When air is injected from the first air inlet pipe and flows out from the air outlet connector B1803, the air flows along the hose through the second air source interface 1302 into the cylinder 13, pushing the piston in the cylinder 13 to reset, retracting the piston rod of the cylinder 13 inward, and driving the sector gear 16 to rotate clockwise, causing the main gear 12 to rotate clockwise, thereby causing the suction nozzle 11 to rotate counterclockwise and be lifted up to wait for the warp to be connected and reset.

[0033] A second solenoid valve 19 is also installed on the inner wall on the other side of the frame 9. The second solenoid valve 19 includes an air inlet connector B1901 and an air outlet connector C1902. The air inlet connector B is connected to the second air inlet pipe, and the air outlet connector C1902 is connected to the air inlet 1102 of the suction nozzle 11 through a hose.

[0034] When air is injected from the second air inlet pipe and flows out from the air outlet connector C1902, the air enters the suction nozzle 11 along the air inlet 1102 of the hose suction nozzle 11, causing negative pressure to be generated in the inner cavity of the suction nozzle 11, and the broken warp yarn 21 is sucked into the suction nozzle 11 through the suction port 1101 of the suction nozzle 11.

[0035] like Figure 5 As shown, the suction nozzle 11 is a negative pressure suction nozzle, including an air inlet 1102, a suction port 1101 and an air outlet 1103. When air flow is injected into the air inlet 1102, the air flow flows out from the air outlet 1103 through the air flow channel 1104. During the flow of air, the air in the inner cavity of the suction nozzle 11 is driven to flow, so that the air in the inner cavity of the suction nozzle 11 flows out from the air outlet 1103, thereby forming a negative pressure in the inner cavity of the suction nozzle 11, and sucking the broken warp yarn 21 into the inner cavity of the suction nozzle 11 through the suction port 1101.

[0036] Preferably, a drag chain 20 is provided on one side of the guide rail bracket 5 , and the first air inlet pipe, the second air inlet pipe and the communication line are placed in the drag chain 20 .

[0037] During the operation of the loom, when the warp yarn 21 breaks, the warp dropper 22 connected thereto falls, triggering the position sensor on the warp stop frame (not shown in the figure), and the position sensor sends a signal to the controller of the electronic control system. After processing the signal, the controller sends a position signal to the reduction motor 7, and the reduction motor 7 drives the transmission screw 6 to rotate to move the transmission seat 8, and brings the suction nozzle 11 to the position where the warp dropper 22 falls; after positioning, the controller sends a command to the first solenoid valve 18, and the air flow enters the cylinder 13 through the first air source interface 1301, extending the piston rod of the cylinder 13, driving the fan gear 16 to rotate counterclockwise, and causing the main gear 12 to rotate clockwise, thereby causing the suction nozzle 11 to rotate clockwise and descend, and descend to the position as shown in the figure. Figure 3 , Figure 4The suction nozzle 11 stops at the position shown, that is, the position where the warp yarn 21 is broken, and then the second solenoid valve 19 is opened, and the air flow flows into the suction nozzle 11 from the air outlet joint C1902, and a negative pressure is formed in the suction nozzle 11, so that the broken warp yarn 21 is sucked into the suction nozzle 11; then, the air outlet joint A1802 is closed, and the air outlet joint B1803 is opened, and the air flow enters the cylinder 13 through the second air source interface 1302, and the piston rod of the cylinder 13 is contracted, driving the fan gear 16 to rotate clockwise, and the main gear 12 to rotate counterclockwise, so that the suction nozzle 11 rotates clockwise and is lifted to a certain height, waiting for the warp to be connected. After the warp is connected, the suction nozzle 11 continues to rotate and be lifted, and returns to the position as shown in the figure. Figure 1 , Figure 2 The position shown stops, and then the first solenoid valve 18 and the second solenoid valve 19 are closed, and no more gas is supplied.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
