Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to an anti-breakage yarn feeding mechanism for an air-jet loom. Background Technology

[0002] An air-jet loom is a shuttleless loom that uses a jet of air to guide the weft yarn through the shed. Its working principle is to use air as the weft-introducing medium; the compressed air jet creates frictional traction on the weft yarn, pulling it through the shed. The jet of air achieves the purpose of weft insertion. Air-jet looms typically require a breakage-prevention feeding mechanism to prevent yarn breakage due to deviation during the feeding process.

[0003] Chinese Patent Publication No. (CN218262959U) discloses an anti-breakage yarn feeding mechanism for an air-jet loom for chemical fiber fabrics. The mechanism includes a base plate, a side plate fixedly connected to the side wall of the base plate, a column fixedly connected to the upper surface of the side plate, and a yarn feeding tube fixedly connected to the top of the column. An early warning mechanism is installed outside the yarn feeding tube, comprising a fixed rod fixedly connected to the outer wall of the yarn feeding tube. In this design, the yarn enters the yarn feeding tube and is ejected from the frame. If the yarn becomes misaligned, the misaligned yarn contacts a roller control slider that controls a first spring to compress. When the slider moves, it contacts a pressure sensor inside the frame. When the pressure sensor is under pressure, it triggers an alarm. This design ensures the stability of the yarn during transmission, thus providing early warning of yarn misalignment and allowing for prediction before breakage.

[0004] However, the above-mentioned utility model still has the following problems: Although the above-mentioned utility model can achieve the early warning effect before yarn breakage, the limited range of motion of the spring driven by the roller results in poor applicability of the device. It can only be used when the yarn deviation is small. In actual use, there will be situations where the yarn deviation is large at any moment. In this case, after the pressure sensor issues an early warning, it will take a certain amount of time for the staff to receive the alarm signal and adjust the position. This may lead to the yarn itself starting to break before the staff can make the adjustment. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a breakage-proof yarn feeding mechanism for an air-jet loom, which has strong applicability and good breakage prevention effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a breakage-proof yarn feeding mechanism for an air-jet loom, comprising a base, an adjustment component fixedly connected to the upper surface of the base, a movable seat provided on the top of the adjustment component, a controller fixedly connected to the upper surface of the movable seat, a cylinder fixedly connected to the top of the movable seat, a lifting plate fixedly connected to the output end of the cylinder, a limit frame fixedly connected to the top of the lifting plate, an elastic rope fixedly connected to the inner wall of the limit frame, a yarn feeding seat fixedly connected to one end of the elastic rope, a yarn feeding hole opened on the outer surface of the yarn feeding seat, a guide rod fixedly connected to the lower surface of the yarn feeding seat, a guide rod groove opened on the inner bottom wall of the limit frame, an installation groove opened on the inner bottom wall of the guide rod groove, and a pressure sensor fixedly connected to the inner wall of the installation groove.

[0007] By adopting the above technical solution, and by setting up an adjustment component, a movable seat, a controller, a lifting plate, a limit frame, an elastic rope, a yarn inlet seat, a guide rod, a guide rod slide, and a pressure sensor, when the yarn shifts within the yarn inlet seat, the elastic rope will stretch, causing the yarn inlet seat to move within the limit frame. When the guide rod at the bottom of the yarn inlet seat contacts the pressure sensor, the pressure sensor transmits a signal to the controller. The controller then controls the drive motor in the adjustment component to operate. Through the transmission cooperation of the lead screw, lead screw slide, and limit rod in the adjustment component, the movable seat is driven... The design moves the yarn feeder until it resets, enabling the determination of the yarn offset direction and the adjustment of the yarn feeder to the left or right by controlling the forward or reverse rotation of the drive motor. The pressure sensors are located on both sides of the center of the limiting frame. When the yarn deviates significantly, the limiting frame and elastic rope can support a large range of movement for the yarn feeder, allowing sufficient time to adjust its position. This prevents the yarn from breaking before adjustment due to a large instantaneous deviation, thus achieving strong applicability and good anti-breakage effect.

[0008] A further feature of this invention is that the number of pressure sensors is two, and the lower surfaces of both pressure sensors are electrically connected to connecting wires, and both connecting wires are electrically connected to the controller.

[0009] By adopting the above technical solution, and by setting a pressure sensor on each of the left and right sides of the infeed seat, the controller can easily determine whether the yarn in the infeed seat has shifted to the left or right.

[0010] A further feature of this invention is that the inner top wall of the limiting frame is provided with a pulley groove, and a small pulley is fixedly connected to the top of the cable inlet seat. There are two small pulleys, and both small pulleys are located inside the pulley groove.

[0011] By adopting the above technical solution and setting pulley grooves and small pulleys, the friction force when the cable inlet seat slides within the limit frame can be reduced.

[0012] A further feature of this invention is that a Teflon ring is fixedly connected to the inner wall of the inlet hole, and the thickness of the Teflon ring is .cm.

[0013] By adopting the above technical solution and setting Teflon rings, the friction between the yarn and the inlet seat can be effectively reduced due to the extremely low coefficient of friction of the Teflon rings, thus avoiding yarn breakage caused by friction.

[0014] A further feature of this invention is that the adjustment assembly includes an adjustment housing and a drive motor, the drive motor is electrically connected to a controller, a lead screw is fixedly connected to the output end of the drive motor, a lead screw slide is threadedly connected to the outer wall of the lead screw, a limit rod is fixedly connected to the upper surface of the lead screw slide, and the limit rod is fixedly connected to a movable seat.

[0015] By adopting the above technical solution and setting an adjustment component, the function of adjusting the cable inlet socket horizontally to the left and right is realized.

[0016] A further feature of this invention is that a slide rail is fixedly connected to the top of the adjustment housing, and a slide groove is provided on the lower surface of the movable seat, wherein the movable seat is slidably connected to the slide rail through the slide groove.

[0017] By adopting the above technical solution and setting slide rails and grooves, the stability of the moving seat when driving the infeed seat to adjust its position can be effectively improved.

[0018] A further feature of this invention is that a bearing seat is fixedly connected to the inner wall of the adjusting housing, and the lead screw is rotatably connected to the bearing seat.

[0019] By adopting the above technical solution and setting a bearing seat, the lead screw is supported and fixed.

[0020] A further feature of this invention is that a limiting connection groove is provided on the upper surface of the adjusting housing, and the limiting rod is slidably connected to the limiting connection groove.

[0021] By adopting the above technical solution and setting the limiting connection groove, it is not only convenient to fix the limiting rod and the moving seat, but also to limit the movement range of the moving seat.

[0022] A further feature of this invention is that a fixed seat is fixedly connected to the upper surface of the base, a roller bracket is provided on the top of the fixed seat, and a lint roller is rotatably connected to the inner side of the roller bracket.

[0023] By adopting the above technical solution and setting up a roller bracket, the lint roller is supported and fixed.

[0024] A further feature of this invention is that: a slot is provided on the upper surface of the fixing base, the roller bracket is located inside the slot, a fixing hole is provided on one side of the fixing base, a plug rod is slidably connected to the inner wall of the fixing hole, and a fixing hole is provided on the outer surface of the roller bracket.

[0025] By adopting the above technical solution, and by setting up a fixed base, roller bracket, lint roller, slot, fixed insertion hole, insertion rod, and fixing hole, the lint roller can remove the lint from the surface of the yarn when it passes through the lint roller before entering the yarn. When the lint roller needs to be replaced, simply pull the insertion rod out of the fixed insertion hole. At this time, the insertion rod leaves the fixing hole on the roller bracket, thus losing its fixation to the roller bracket. The operator can then pull the lint roller and roller bracket out of the slot. This design not only removes lint from the surface of the yarn during the yarn entering the yarn, preventing the yarn from breaking due to increased friction caused by excessive lint, thus further improving the anti-breakage effect of the device, but also facilitates the disassembly and assembly of the lint roller, enhancing the ease of use of the device.

[0026] The beneficial effects of this utility model are as follows: By setting up an adjustment component, a movable seat, a controller, a lifting plate, a limiting frame, an elastic rope, a yarn inlet seat, a guide rod, a guide rod groove, and a pressure sensor, when the yarn deviates within the yarn inlet seat, the elastic rope will stretch, causing the yarn inlet seat to move within the limiting frame. When the guide rod at the bottom of the yarn inlet seat contacts the pressure sensor, the pressure sensor transmits a signal to the controller. The controller then controls the drive motor in the adjustment component to operate. Through the transmission cooperation of the lead screw, lead screw slide, and limiting rod in the adjustment component, the movable seat is driven to move the yarn inlet seat until it resets. This design realizes the function of judging the direction of yarn deviation and adjusting the yarn inlet seat to the left or right by controlling the forward or reverse rotation of the drive motor. Furthermore, the pressure sensor is located on both sides of the middle of the limiting frame. When the yarn deviates significantly, the limiting frame and the elastic rope can support the movement of the yarn inlet seat within a certain range. The device has a large surrounding area, allowing sufficient time for adjusting the position of the yarn feeder. This prevents yarn breakage due to large instantaneous deviations before adjustment, thus achieving strong applicability and good anti-breakage effect. By incorporating a fixed base, roller support, lint roller, slot, fixed insertion hole, insertion rod, and fixing hole, the lint roller removes lint from the yarn surface before it enters the machine. When the lint roller needs to be replaced, simply pull the insertion rod out of the fixed insertion hole. This releases the rod from the fixing hole on the roller support, allowing the operator to easily remove the lint roller and roller support from the slot. This design not only removes lint from the yarn surface during the yarn feeding process, preventing breakage due to increased friction caused by excessive lint, further improving the anti-breakage effect, but also facilitates the disassembly and assembly of the lint roller, enhancing the ease of use of the device.
