Description

Technical Field

[0001] The present invention relates to the technology of yarn bobbin feeding equipment, and particularly to a yarn bobbin feeding device for a yarn covering machine. Background Art

[0002] With the development of industrial economy, industrial mechanization and intelligentization are gradually deepening. In the textile field, many spun yarns need to be wound into rolls. In order to improve the winding efficiency of the yarn, a yarn covering machine is required. When the yarn covering machine winds the yarn, a yarn bobbin is needed, and when using the yarn bobbin, the yarn bobbin needs to be fed. In order to improve the feeding efficiency of the yarn bobbin, a corresponding yarn bobbin feeding device is needed.

[0003] In the Chinese invention patent with the publication number of CN111994731B, a yarn bobbin feeding device for a yarn covering machine is disclosed. In this yarn bobbin feeding device for a yarn covering machine, a dislocation mechanism is installed between the telescopic cylinder and the feeding plate. The dislocation mechanism mainly includes two parts. One is a ball head arranged between the sliding bar and the feeding plate. Preferably, a ball socket capable of accommodating the ball head is arranged on the bottom surface of the feeding plate. When the feeding plate tilts left or right, the ball head can rotate in the ball socket, which is equivalent to hinging the feeding plate and the sliding member, so as to adapt to the displacement generated when the feeding plate tilts. The other is that the sliding bar is arranged in the sliding groove on the top surface of the dislocation plate. When the feeding plate tilts left or right, the sliding bar can move left or right in the sliding groove, so as to adapt to the displacement of the sliding bar when the feeding plate tilts. In summary, the dislocation mechanism can make the feeding plate tilt left or right according to actual needs.

[0004] During the feeding process of the existing equipment, due to the continuous feeding of multiple yarn bobbins, the yarn bobbins may get stuck or deviate from the correct feeding position, resulting in production interruption or uneven covering of the yarn. At the same time, due to inaccurate positioning during the feeding process of the yarn bobbins, the yarn bobbins may fall or be damaged, resulting in the stoppage of the production line and damage to the products. Therefore, a yarn bobbin feeding device for a yarn covering machine has been developed. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Embodiment: Please refer to Figures 1-8 , a yarn bobbin feeding device of a yarn covering machine, which includes a conveying platform 1. A telescopic member 11 is fixedly installed at the upper end of the conveying platform 1. At the same time, a guide groove 12 is provided on the upper end of the conveying platform 1 and on one side of the telescopic member 11. A feeding assembly 3 is slidably installed on the inner wall of the guide groove 12. The yarn bobbin is transferred to a specified position through the feeding assembly 3.

[0036] In this solution, the telescopic member 11 is a device with a telescopic function such as an electric telescopic rod and is connected to an external control device. At the same time, when the telescopic member 11 is started, it synchronously drives the feeding assembly 3 to move along the inner wall of the guide groove 12. Multiple groups of tooth blocks are provided on the inner wall of the guide groove 12, and convex blocks corresponding to the tooth blocks are provided at the lower end of the feeding assembly 3. The outer surface of the tooth block meshes with the outer surface of the convex block, so that when the feeding assembly 3 moves, the feeding assembly 3 can be driven to rotate synchronously as a whole when moving in cooperation with the gear, and then the yarn bobbin is fed to the specified position.

[0037] Further, among them, the feeding assembly 3 includes a bottom plate 31 slidably connected to the conveying platform 1. A sleeve 36 is fixedly installed at the end of the bottom plate 31, and a positioning cylinder 361 is slidably installed on the inner wall of the sleeve 36. A fixing block 39 is fixedly installed at one end of the positioning cylinder 361 away from the sleeve 36.

[0038] In this embodiment, a chute is provided on the inner wall of the sleeve 36. At the same time, a slider corresponding to the chute is provided on the outer surface of the positioning cylinder 361. The outer surface of the slider is slidably connected to the inner wall of the chute. Therefore, when the positioning cylinder 361 is stressed, it is ensured that the positioning cylinder 361 only moves along the inner wall of the chute and the positioning cylinder 361 remains stable.

[0039] Further, a plurality of limiting rods 391 are rotatably installed on the outer surface of the fixing block 39, and the plurality of limiting rods 391 are evenly distributed on the outer surface of the fixing block 39. A docking block 392 is rotatably installed at the end of the limiting rod 391, and the inner wall of the yarn bobbin is fitted by the docking block 392; a positioning rod 393 is rotatably installed at the middle position of the outer surface of the limiting rod 391, and a circular ring 394 is rotatably installed at the end of the positioning rod 393. A driving shaft 341 is slidably installed on the inner wall of the fixing block 39, and the outer surface of the driving shaft 341 is slidably connected to the inner wall of the circular ring 394.

[0040] Specifically, when the driving shaft 341 rotates, it synchronously drives the circular ring 394 rotatably installed on its outer surface to move. Since the positioning rod 393 is rotatably installed on the outer surface of the circular ring 394, when the circular ring 394 moves, the limiting rod 391 is driven to rotate around the outer surface of the fixing block 39 in cooperation with the positioning rod 393, thereby driving the docking block 392 rotatably installed at the end of the limiting rod 391 to expand outward or contract inward. The inner wall of the yarn bobbin is fixed by the expansion of the docking block 392, which is convenient for transferring the yarn bobbin. A non-slip component such as rubber is provided on the outer surface of the docking block 392.

[0041] Further, a driving member 32 is fixedly installed on the inner wall of the bottom plate 31. The output end of the driving member 32 is fixedly installed with a first turntable 37, and a driving block 321 is fixedly installed at the output end of the driving member 32 and on one side of the first turntable 37.

[0042] Specifically, the driving member 32 is a device with power output such as a motor and is connected to an external control device. When the driving member 32 is started, it synchronously drives the first turntable 37 and the driving block 321 provided at its output end to rotate synchronously.

[0043] Further, a guide plate 33 is fixedly installed on the inner wall of the bottom plate 31 and on the side far from the driving member 32. A movable plate 331 is slidably installed on the inner wall of the guide plate 33. An arc-shaped plate 322 is fixedly installed at the end of the movable plate 331, and the inner wall of the arc-shaped plate 322 is slidably connected to the outer surface of the end of the driving block 321.

[0044] Specifically, when the driving block 321 rotates, it synchronously drives the arc-shaped plate 322 to move. Since the end of the arc-shaped plate 322 is fixedly connected to the movable plate 331, when the arc-shaped plate 322 moves, the movable plate 331 is driven to move along the inner wall of the guide plate 33.

[0045] Further, a positioning block 34 is fixedly installed at the end of the guide plate 33, and the inner wall of the positioning block 34 is slidably connected to the outer surface of the driving shaft 341. At the same time, the end of the driving shaft 341 is rotatably connected to the end of the movable plate 331.

[0046] Specifically, two protective rods are provided at the end of the movable plate 331. At the same time, an annular groove is formed on the outer surface of the end of the drive shaft 341, and the inner wall of the annular groove is slidably connected to the outer surfaces of the two protective rods. The protective rods are arranged on both sides of the annular groove, so as to ensure that the drive shaft 341 can rotate freely when it moves under force.

[0047] Further, a rotating cylinder 35 is rotatably installed at the end of the positioning block 34. An arc-shaped groove 351 is formed on the outer surface of the rotating cylinder 35, and the inner wall of the rotating cylinder 35 is slidably connected to the outer surface of the drive shaft 341. A second turntable 38 is rotatably installed on one side of the bottom plate 31. A transmission member 371 is arranged between the first turntable 37 and the second turntable 38. At the same time, a push block 381 is fixedly installed at the end of the second turntable 38, and the outer surface of the push block 381 is slidably connected to the inner wall of the arc-shaped groove 351.

[0048] Specifically, when the first turntable 37 rotates, it drives the second turntable 38 to rotate through the transmission member 371. Since the push block 381 is fixedly installed at the end of the second turntable 38, the push block 381 rotates synchronously with the second turntable 38. The transmission member 371 is a component with a transmission function such as a transmission belt.

[0049] Since the outer surface of the push block 381 is slidably connected to the inside of the arc-shaped groove 351, when the push block 381 rotates, it drives the rotating cylinder 35 to rotate around the end of the positioning block 34. A clamping block is arranged on the outer surface of the drive shaft 341, and a clamping groove is formed on the inner wall of the rotating cylinder 35. The outer surface of the clamping block is slidably connected to the inner wall of the clamping groove. Therefore, when the rotating cylinder 35 rotates, it synchronously drives the drive shaft 341 to rotate, and at the same time, it does not interfere with the telescopic movement of the drive shaft 341. The arc-shaped groove 351 is composed of two inclined sliding grooves, and the two sliding grooves are cross-distributed. The unfolded state of the arc-shaped groove 351 is in an X shape.

[0050] Further, a conveying assembly 2 is assembled on the upper end of the conveying platform 1, and the yarn bobbin is quantitatively conveyed through the conveying assembly 2. The conveying assembly 2 includes a fixing plate 21 fixedly connected to the conveying platform 1. A power member 22 is fixedly installed at the end of the fixing plate 21, and a screw rod 23 is fixedly installed at the output end of the power member 22.

[0051] In this embodiment, the power member 22 is a device with power output such as a motor, and is connected to an external control device. When the power member 22 is started, it synchronously drives the screw rod 23 fixedly installed at its output end to rotate.

[0052] Further, a guide rail 24 is fixedly installed on the upper end of the fixing plate 21, and an adjusting block 25 is slidably installed on the outer surface of the guide rail 24. At the same time, the outer wall of the adjusting block 25 away from the inner wall of the guide rail 24 is slidably connected to the outer surface of the screw rod 23.

[0053] Specifically, when the screw rod 23 rotates, it synchronously drives the adjustment block 25 slidably mounted on its outer surface to move. At the same time, the lower end of the adjustment block 25 is slidably connected to the outer surface of the guide rail 24. Thus, when the adjustment block 25 moves, it is limited by the guide rail 24 to ensure that the adjustment block 25 remains stable during movement.

[0054] Furthermore, a rotating shaft 26 is rotatably mounted on one side of the adjustment block 25. A roller 29 is fixedly mounted at the end of the rotating shaft 26. A groove 291 is formed on the outer surface of the roller 29 to convey the yarn bobbin through the groove 291.

[0055] Specifically, when the rotating shaft 26 rotates, it synchronously drives the roller 29 fixedly mounted at its end to rotate. And a groove 291 is formed on the outer surface of the roller 29 to perform directional transmission of the yarn bobbin in cooperation with the groove 291.

[0056] Furthermore, the end of the rotating shaft 26 penetrates and extends to the other end of the adjustment block 25. At the same time, a swing block 27 is fixedly mounted at the end of the rotating shaft 26. A rotating block 271 is fixedly and rotatably mounted at the end of the swing block 27 away from the rotating shaft 26. An inclined plate 28 is fixedly mounted on one side of the fixing plate 21. The outer surface of the inclined plate 28 is slidably connected to the outer surface of the rotating block 271.

[0057] Specifically, when the adjustment block 25 moves, it drives the swing block 27 to move in cooperation with the rotating shaft 26. Since the rotating block 271 at the end of the swing block 27 is slidably connected to the outer surface of the inclined plate 28, when the adjustment block 25 moves, when the swing block 27 is driven to slowly move along the inclined plate 28, the swing block 27 drives the rotating shaft 26 to rotate, and then drives the roller 29 to rotate and drives the yarn bobbin to be conveyed. At the same time, a torsion spring is sleeved on the outer surface of the rotating shaft 26, and one end of the torsion spring is fixedly connected to the swing block 27, and the other end is connected to the end of the adjustment block 25. Thus, when the rotating shaft 26 rotates, the torsion spring is compressed, and when the swing block 27 returns, a reaction force is provided to enable the swing block 27 to quickly return to the initial position, further improving the stability of the rotating shaft 26.

[0058] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a mini computer. Compared with the general-purpose microprocessor applied in a personal computer, it emphasizes more on self-supply (without external hardware) and cost saving. Its greatest advantage is its small size and can be placed inside the instrument, but its storage capacity is small, the input and output interfaces are simple, and the function consumption is low.

[0059] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
