Technical Field

[0001] This utility model relates to the technical field of yarn finding equipment, and in particular to an equal-spacing conveying type yarn finding device. Background Technology

[0002] In the textile production process, the ends of yarn in bobbins need to be spliced. Currently, most manufacturers still rely on manual methods to find the yarn ends on the surface of the bobbins. However, there are two problems in actual operation: First, manual yarn finding is easily affected by factors such as the worker's eyesight and fatigue level. After a long period of operation, it is impossible to find the yarn ends quickly, which affects the subsequent production process. Second, manual yarn finding is prone to damaging and contaminating the bobbins, affecting the appearance quality of the yarn. Utility Model Content

[0003] In view of the problems of slow speed, impact on subsequent production processes, and easy damage and contamination of yarn bobbins caused by the current method of manually finding yarn heads, this utility model provides an evenly spaced conveying type yarn finding device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A yarn guiding and yarn finding device with equal spacing includes a frame, a conveying component and a yarn suction head component. The conveying component is disposed on the frame, and the yarn suction head component is disposed on one side of the frame. The yarn suction head component includes a cylinder, a yarn suction nozzle and a fan. The fan is connected to the yarn suction nozzle through a connecting pipe. The cylinder drives the yarn suction nozzle to move closer to or away from the yarn package by changing its extension and retraction posture.

[0006] Furthermore, the conveying assembly includes a chain, a plurality of yarn bobbins, and a plurality of guide shafts. Each yarn bobbin is fixedly connected to the chain, and the yarn bobbins are disposed on the yarn bobbins. The chain drives each yarn bobbin to move under the drive of a motor. Each guide shaft is provided with a plurality of gears, and the chain meshes with each of the gears. The motor is drively connected to the guide shaft.

[0007] Furthermore, there are four guide shafts, all rotatably connected to the frame, and each guide shaft has two gears. There are two chains, which mesh with the gears located on the same side of each guide shaft.

[0008] Furthermore, a fixed frame is rotatably connected to the bottom of the yarn bobbin, and the end of the fixed frame is fixedly connected to the chain. A yarn bobbin roller is provided at the bottom of the yarn bobbin, and the yarn bobbin roller protrudes from the fixed frame.

[0009] Furthermore, the frame is connected to a rotating motor via an adjustment unit, and the rotating motor is connected to a motor roller, which contacts the yarn package roller.

[0010] Furthermore, the adjustment unit includes a spring bracket, a connecting plate, and several sliding rods. The spring bracket is fixedly connected to each of the sliding rods, and a spring is sleeved on each of the sliding rods. The connecting plate is slidably connected to each of the sliding rods and is fixedly connected to the rotating motor.

[0011] Furthermore, the yarn suction head assembly also includes a slide rail, a slider, a cylinder bracket, and a positioning plate. The slide rail is fixedly connected to the frame, the slider is disposed on the slide rail, the cylinder bracket is fixed on the slider, the positioning plate has a C-shaped cross-section, the yarn suction head nozzle is located in the positioning plate, and is fixedly connected to the cylinder bracket through the connecting pipe.

[0012] Furthermore, the cylinder is divided into a first cylinder and a second cylinder. One end of the first cylinder is connected to the frame, and the other end is connected to the cylinder bracket. One end of the second cylinder is connected to the cylinder bracket, and the other end is connected to the positioning plate. The second cylinder drives the positioning plate to move relative to the yarn suction head.

[0013] Furthermore, the cross-section of the yarn suction head is pentagonal, and a yarn suction port is provided at the outer curved edge of the yarn suction head. The yarn suction port is inclined to match the outer contour of the yarn package. The inner sidewall of the yarn suction head is funnel-shaped, and the connecting tube is connected to the lowest point of the inner sidewall of the yarn suction head.

[0014] Furthermore, the yarn suction head assembly also includes a controller, a pressure sensor, and a photoelectric sensor. The controller is connected to the pressure sensor and the photoelectric sensor respectively. The pressure sensor is disposed on the positioning plate at the position where it contacts the yarn package, and the photoelectric sensor is disposed inside the connecting tube.

[0015] The beneficial effects of this invention are as follows: In this invention, the conveying component and the yarn suction head component work together.

[0025] This utility model discloses an equidistant conveying type yarn guiding and yarn finding head device. The following describes one embodiment of this utility model in detail with reference to the accompanying drawings.

[0026] Combination Figure 1 and Figure 2 As shown, the yarn finding device includes a frame 1, a conveying assembly, and a yarn suction head assembly. The conveying assembly is mounted on the frame 1. The conveying assembly includes a rotating motor 7, two chains 2, several yarn bobbins 5, and four guide shafts 4. Each guide shaft 4 is rotatably connected to the frame 1 via bearings, and the guide shafts 4 are arranged in an approximately rectangular pattern. Gears are fixed on both sides of each guide shaft 4, and the two chains 2 mesh with the gears located on the same side of the guide shaft 4. A motor is fixed on the frame 1, and the motor is connected to a guide pull drive to move the two chains 2. The bottom of the yarn bobbin 5 has a yarn bobbin roller 6, and a fixed frame 3 is rotatably connected between the yarn bobbin 5 and the yarn bobbin roller 6. This connection is located in the middle of the fixed frame 3, and the two ends of the fixed frame 3 are fixedly connected to the two ends located on both sides of the yarn bobbin 5. The yarn bobbins 20 are appropriately matched and mounted on the yarn bobbin 5.

[0027] The rotating motor 7 is connected to the frame 1 via an adjusting part, which includes a spring bracket 9, a connecting plate 8, and two sliding rods. The spring bracket 9 is fixedly connected to the frame 1, and the two sliding rods are fixed to the spring bracket 9. The connecting plate 8 is fitted onto the two sliding rods through through holes and moves along the two sliding rods. Springs are sleeved on the sliding rods, and the springs are located between the spring bracket 9 and the connecting plate 8. Nuts are threaded to the outer ends of both sliding rods to prevent the connecting plate 8 from detaching from the sliding rods. The rotating motor 7 is fixedly connected to the connecting plate 8 and located between the two sliding rods.

[0028] Combination Figure 3 and Figure 4 As shown, the yarn suction head assembly is located on one side of the frame 1. The assembly includes a first cylinder 12, a second cylinder 14, a cylinder bracket 13, a slide rail 18, a slider 19, a suction head nozzle 16, a positioning plate 15, and a fan. An extension plate 11 protrudes outward from one side of the frame 1. The slide rail 18 is arranged in a direction perpendicular to the movement direction of the yarn package 20 and is fixedly connected to the top of the extension plate 11. The slider 19 is mounted on the slide rail 18, and the cylinder bracket 13 is fixedly connected to the top of the slider 19. One end of the first cylinder 12 is fixedly connected to the extension plate 11, and the other end is fixedly connected to the bottom of the cylinder bracket 13. The first cylinder 12 drives the slider 19 to move along the slide rail 18. One end of the second cylinder 14 is fixedly connected to the cylinder bracket 13, and the other end is fixedly connected to the lower side wall of the positioning plate 15. Figure 5 , Figure 6 as well as Figure 7 As shown, the cross-section of the positioning plate 15 is approximately C-shaped. The yarn suction nozzle 16 is located within the positioning plate 15. The inner wall of the yarn suction nozzle 16 is funnel-shaped, with its lowest point located in the middle of the inner wall, and is connected to a connecting pipe 17. Figure 8 and Figure 9 As shown, the inner wall of the funnel-shaped yarn suction nozzle 16 facilitates the smooth entry of yarn ends into the connecting tube 17. The upper part of the positioning plate 15 has a notch, through which the connecting tube 17 passes and is fixedly connected to the cylinder bracket 13. The cross-section of the yarn suction nozzle 16 is approximately pentagonal, and a yarn suction port 21 is provided at the bent vertical edge of the outer side of the yarn suction nozzle 16. The yarn suction port 21 is inclined to fit the outer contour of the yarn package 20. A blower is connected to the connecting tube 17 via a flexible hose. The blower is used to drive the airflow in a directional direction and generate negative pressure to suck up the yarn ends. The yarn suction head assembly also includes a controller, a pressure sensor, and a photoelectric sensor. The controller is connected to both the pressure sensor and the photoelectric sensor. The pressure sensor is positioned on the positioning plate 15 at the contact point with the yarn package 20, and the photoelectric sensor is located inside the connecting tube 17.

[0029] During operation, the existing flipping robot places the yarn package 20 onto the yarn package shaft 5. A motor provides power, moving the yarn package 20. The rotating motor 7, adjacent to the yarn suction head assembly, drives the motor roller 10 to rotate. Once the yarn package 20 reaches the appropriate position, the motor roller 10, through friction, drives the yarn package roller 6 to rotate. The yarn package roller 6, via the yarn package shaft 5, drives the yarn package 20 to rotate. The motor roller 10 and the yarn package roller 6 are interference-fitted through an adjusting part to ensure close contact, generating sufficient friction to ensure smooth rotation of the yarn package roller 6. The operator adjusts the spring force by adding or removing shims between the spring bracket 9 and the spring, thereby adjusting the contact distance between the motor roller 10 and the yarn package roller 6.

[0030] After the yarn package 20 moves to the appropriate position, the second cylinder 14 drives the positioning plate 15 to extend towards the yarn package 20. Simultaneously, the first cylinder 12 drives the slider 19 and cylinder support 13 to move towards the yarn package 20, bringing the suction nozzle 16 closer to the yarn package 20. The controller, detecting contact with the yarn package 20 via a pressure sensor on the positioning plate 15, controls the first cylinder 12 to stop moving and controls the second cylinder 14 to retract the positioning plate 15 a suitable distance, ensuring a 2mm distance between the outer end of the positioning plate 15 and the suction port 21 of the suction nozzle 16, preventing contact between the suction nozzle 16 and the yarn package 20. Once the yarn package 20 has moved to the appropriate position, the motor roller 10 on the rotating motor 7 makes close contact with the yarn package roller 6.

[0031] After the fan starts working, a negative pressure is generated inside the yarn suction nozzle 16. The side walls on both sides of the positioning plate 15 are used to concentrate the airflow, so that there is a certain airflow pressure around the yarn suction nozzle 16. The yarn suction nozzle 16 finds the yarn end during the rotation of the yarn bobbin 20. After the yarn suction nozzle 16 finds the yarn end and sucks it into the connecting pipe 17, the controller detects the yarn end through the photoelectric sensor, controls the fan to stop rotating, and controls the first cylinder 12 to reset. Then the motor drives the next yarn bobbin 20 to move to the appropriate position through the chain 2.

[0032] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
