Description

Technical Field

[0001] This utility model relates to the technical field of textile machinery, and in particular to a yarn storage cylinder and a yarn storage device. Background Technology

[0002] The yarn storage device mainly includes a housing, a main shaft and a yarn storage cylinder mounted on it. A pressure ring and a tension ring are fitted on the yarn storage cylinder. The main shaft is located at the center of the yarn storage cylinder. The main shaft drives the yarn storage cylinder to rotate to store yarn. The stored yarn is the yarn that is stored on the yarn storage cylinder. The delivered yarn is the yarn that is output after passing through the tension ring.

[0003] The yarn storage process of the yarn accumulator is as follows: The motor rotates, driving the yarn accumulator drum to rotate. During the yarn storage process, the yarn continuously increases on the yarn accumulator drum. As the yarn increases, the pressure ring moves upward continuously. When the pressure ring moves upward to a certain extent, it disconnects from the switch device, at which point the motor stops rotating, and yarn storage stops. As the yarn feeding process continues, the yarn on the yarn accumulator drum continuously decreases, and the pressure ring also moves downward. When it moves downward to a certain extent, it triggers the switch to open, and the motor continues to work, driving yarn storage, and so on in a cycle.

[0004] The existing yarn storage cylinder has a cylindrical structure for its yarn storage area, meaning that the outer diameter is equal from top to bottom. However, this structure has the following drawbacks: when storing yarn, because the outer diameter of the yarn storage cylinder is equal from top to bottom, the yarn tends to get tangled at the same height during the rotation of the yarn storage cylinder. This results in more and more yarn at the same height of the yarn storage cylinder, causing yarn stacking problems, which is not conducive to yarn delivery. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this utility model is to provide a yarn storage cylinder and a yarn storage device. The yarn storage cylinder is provided with a truncated cone surface that is larger at the top and smaller at the bottom, so that the yarn can be dropped more smoothly, the yarn output efficiency is higher, and the yarn stacking phenomenon is effectively reduced.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a yarn storage cylinder, including a yarn storage cylinder body, the yarn storage cylinder body is provided with a yarn storage surface for winding yarn, the yarn storage surface is a frustum surface that is larger at the top and smaller at the bottom, the angle between the generatrix of the frustum surface and the axis is A, where 0.3°≤A≤5°, so that during the yarn storage process, the yarn wound to the yarn storage cylinder body will gradually move downward during the rotation of the yarn storage cylinder body.

[0007] Furthermore, where 0.5°≤A≤1.5°.

[0008] Furthermore, the yarn storage cylinder body is provided with multiple circumferentially arranged columnar parts, with a spacer cavity between adjacent columnar parts, and the outer periphery of the columnar parts fits to form a frustum surface.

[0009] Furthermore, the lower end of the yarn storage cylinder body corresponding to the yarn storage surface is provided with a limiting flange.

[0010] A yarn storage device includes a machine body, a motor, and a yarn storage cylinder as described in any of the above. The yarn conveying cylinder is rotatably connected to the machine body. The motor is used to drive the yarn conveying cylinder to rotate. A yarn pressing ring is sleeved on the yarn storage cylinder. An electrical control module is provided inside the machine body.

[0011] Furthermore, the yarn storage device is equipped with an empty yarn reminder device, which includes a mounting base, a lever, a retaining element, a detection component, and an alarm element. The mounting base is fixedly connected to the yarn storage cylinder and located within the yarn storage surface area. The lever is rotatably connected to the mounting base and can rotate both extending out of the yarn storage surface and retracting into the yarn storage surface. The retaining element acts on the lever to keep it extending out of the yarn storage surface. The detection component includes a magnetic block fixedly installed on the lever and a Hall element fixedly installed on the machine body. The Hall element, the alarm element, and the control module are electrically connected.

[0012] Furthermore, the retaining member includes a first magnetic element fixedly connected to the mounting base and a second magnetic element fixedly mounted to the paddle, wherein the first magnetic element and the second magnetic element repel each other due to their different shapes, so that the paddle tends to extend beyond the yarn storage surface area.

[0013] Furthermore, the lever and the mounting base cooperate to form a limiting structure. The limiting structure includes a limiting plate set at an angle to the lever and a limiting surface set on the mounting base. The limiting surface and the limiting plate cooperate to limit the angle at which the lever rotates out of the yarn storage area.

[0014] In summary, this utility model has the following beneficial effects: 1. The yarn storage cylinder has a truncated cone-shaped surface that is larger at the top and smaller at the bottom, which makes yarn feeding and delivery smoother and effectively reduces yarn stacking. Specifically, the yarn storage cylinder is designed as a truncated cone structure that is larger at the top and smaller at the bottom. During the yarn storage process, the yarn wound onto the yarn storage cylinder will move downward as the yarn storage cylinder rotates. For example, the innermost yarn will gradually move downward as the yarn storage cylinder rotates. This can prevent the yarn from continuously winding at the same height and thus prevent the problem of yarn stacking.

[0015] 2. When the yarn storage cylinder is wound with yarn, the lever retracts into the yarn storage area under the pressure of the yarn. When the yarn is about to be unwound, the pressure of the yarn on the lever disappears, and the lever extends out of the yarn storage area under the action of the retainer. The Hall element determines that the unwinding is about to be completed based on the position of the magnetic block and reminds the operator through the warning element. Attached Figure Description

The angle between the generatrix 12 of the frustum-shaped surface and the axis 13 is A, where 0.3°≤A≤5°. Preferably, 0.5°≤A≤1.5°. By setting the frustum-shaped surface of the yarn storage cylinder to be larger at the top and smaller at the bottom, the yarn that is initially wound onto the yarn storage cylinder body 10 during the yarn doffing and storage process will gradually move downwards as the yarn storage cylinder body 10 rotates, making the yarn doffing smoother, increasing the yarn output efficiency, and effectively reducing yarn stacking.

[0026] In some embodiments, the yarn storage cylinder body 10 is provided with a plurality of circumferentially arranged columnar portions 14, and an interval cavity 15 is provided between adjacent columnar portions 14, with the outer periphery of the columnar portions 14 forming a frustum.

[0027] In some embodiments, the yarn storage cylinder body 10 is provided with a limiting flange 16 at the lower end corresponding to the yarn storage surface 11.

[0028] A yarn storage device includes a body 20, a motor, and a yarn storage cylinder as described in any of the above. The yarn conveying cylinder is rotatably connected to the body 20. The motor is used to drive the yarn conveying cylinder to rotate. A yarn pressing ring is sleeved on the yarn storage cylinder. An electrical control module is provided inside the body 20.

[0029] In some embodiments, the yarn storage device is provided with an empty yarn reminder device, which includes a mounting base 30, a lever 40, a retaining member 50, a detection component 60, and an alarm element. The mounting base 30 is fixedly connected to the yarn storage cylinder and located in the area of ​​the yarn storage surface 11. The lever 40 is rotatably connected to the mounting base 30 and can rotate to extend out of the yarn storage surface 11 and retract into the yarn storage surface 11. The retaining member 50 acts on the lever 40 to keep the lever 40 extended out of the yarn storage surface 11. The detection component 60 includes a magnetic block 61 fixedly installed on the lever 40 and a Hall element 62 fixedly installed on the machine body 20. The Hall element 62 and the alarm element are electrically connected to the control module. The lever 40 is located in the area of ​​the partition cavity 15. The alarm element can be a warning light, a buzzer, etc.

[0030] In some embodiments, the retaining member 50 includes a first magnetic member 51 fixedly connected to the mounting base 30 and a second magnetic member 52 fixedly installed on the paddle block 40. The first magnetic member 51 and the second magnetic member 52 are repelled by their different shapes, so that the paddle block 40 tends to stay outside the area of ​​the yarn storage surface 11.

[0031] The lever 40 and the mounting base 30 cooperate to form a limiting structure. The limiting structure includes a limiting plate 41 set at an angle to the lever 40 and a limiting surface 31 set on the mounting base 30. The limiting surface 31 and the limiting plate 41 cooperate to limit the angle at which the lever 40 rotates out of the yarn storage surface 11 area.

[0032] When the yarn storage cylinder is wound with yarn, the lever 40 retracts into the area of ​​the yarn storage surface 11 under the pressure of the yarn. When the yarn is about to be unwound, the pressure of the yarn on the lever 40 disappears, and the lever 40 extends out of the area of ​​the yarn storage surface 11 under the action of the retainer 50. The Hall element 62 judges that the unwinding is about to be completed based on the position of the magnetic block 61 and reminds the operator through the warning element.
