Description

Technical Field

[0001] This utility model belongs to the field of chemical fiber staple fiber technology and relates to an automated rotary yarn take-up device. Background Technology

[0002] In the production of synthetic fiber staple fibers (melt spinning process for polyester, nylon, etc.), the fiber raw materials need to be evenly spread in the barrel after being fed from the spinning feeder for subsequent processing.

[0003] However, current technology uses reciprocating take-up machines. Some processes require changing the take-up method to rotary take-up. Traditionally, converting reciprocating take-up to rotary take-up requires completely dismantling the reciprocating take-up machine and installing a rotary take-up machine, or it requires two workers to manually rotate the disc to make the yarn spool rotate to take up the yarn. If a rotary take-up machine is installed, the cost is too high. Manually rotating the disc has several problems: the yarn spool is prone to deviation, and the yarn often does not wind up to the correct position; the rotation speed is inconsistent, causing the yarn to become tangled in the yarn spool, making it easy to knot and difficult to pull out; it is inefficient and has a low load capacity.

[0004] To address the aforementioned issues, patent CN117702293B discloses a filament collection system and method for preparing para-aramid staple fibers. This method achieves continuous collection of filaments through a feeding device and a reciprocating filament container. Its core lies in stacking the filaments using a combination of gravity and lateral movement, reducing manual intervention. However, in practical applications, the filaments may shift laterally due to inertia or uneven tension, resulting in uneven filament stacking. Furthermore, the reciprocating motion driven by a servo motor is prone to slippage and knotting between filament layers due to uneven speed. Additionally, the system has limited load-bearing capacity, supporting only small- to medium-scale production.

[0005] Therefore, it is of great significance to study an automated rotary wire take-up device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the prior art and to provide an automated rotary wire take-up device.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An automated rotary wire take-up device includes a geared motor, a pulley assembly, an upper plate, an intermediate connecting rod, an intermediate support disc, a bearing assembly, and a fixed load-bearing assembly;

[0009] The intermediate connecting rod comprises, from top to bottom, an upper part, a middle part, and a lower part;

[0010] The pulley assembly is used to transmit power and regulate speed. Due to the simple structure of belt drive, no lubrication is required, and the failure rate is reduced by more than 50%. The pulley assembly includes a first pulley, a second pulley, and a belt. The first pulley and the second pulley are connected in series by the belt. The geared motor is connected to the first pulley. The upper part of the intermediate connecting rod is connected to both the second pulley and the upper plate. The upper plate is located above the second pulley, so that the upper plate rotates under the drive of the geared motor.

[0011] The lower part of the intermediate connecting rod is inserted through the bearing assembly;

[0012] The bearing assembly is located inside the fixed bearing group; the fixed bearing group is used to provide load-bearing stability for the turntable winding device; the fixed bearing group includes an intermediate sleeve, a base sleeve, and a base arranged sequentially from top to bottom, and the intermediate support disc is fitted outside the intermediate sleeve; the intermediate support disc can bear the weight of the yarn in the spinning drum and the weight of the turntable body, and at the same time distribute the pressure evenly to the intermediate support disc. Since it needs to span between two rows of square tubes, in order to ensure that it will not damage the original equipment, the intermediate support disc needs to be made larger, which can also increase the contact area to reduce the pressure.

[0013] As a preferred technical solution:

[0014] As described above, in an automated rotary yarn take-up device, the geared motor is a 220V / 250W AC speed-regulating geared motor used to provide a power source. The geared motor is equipped with a speed regulator with a speed range of 0 to 15 r / min. This allows the centrifugal force field to generate radial acceleration in the fiber bundle, achieving uniform material distribution between layers in the cylinder (CV value < 8%), effectively avoiding fiber entanglement, and providing a semi-finished product that conforms to the layup density gradient for subsequent processes.

[0015] In any of the preceding automated rotary wire take-up devices, the middle diameter of the intermediate connecting rod is larger than both the upper and lower diameters.

[0016] As described above, an automated rotary wire winding device includes a first locking sleeve inside a first pulley and a second locking sleeve inside a second pulley. The geared motor is connected to the first pulley through the first locking sleeve, and the second pulley is connected to the upper part of the intermediate connecting rod through the second locking sleeve. The intermediate connecting rod is driven to rotate by the belt, which in turn drives the upper plate connected to the top of the intermediate connecting rod to rotate, forming a two-stage reduction and torque increase (i.e., achieving two-stage reduction while increasing torque). Compared with traditional gear transmission, it has the advantages of low transmission noise, low maintenance cost, and flexible speed ratio adjustment.

[0017] As described above, an automated rotary yarn take-up device includes a bearing assembly comprising a first bearing, a second bearing, a third bearing, a fourth bearing, a positioning sleeve one, and a positioning sleeve two. The second bearing consists of two parts, designated as second bearing I and second bearing II. The bearing assembly provides axial and radial support for the intermediate connecting rod. Positioning sleeves one and two limit the bearings within the bearing assembly, ensuring the axial stability of the intermediate connecting rod during rotation and allowing for precise control of the rotary table's axial positioning. This prevents fiber entanglement and displacement, reduces vibration errors, and ensures uniform fiber thickness. Positioning sleeve one, positioning sleeve two, and the intermediate support disc are all precision-machined from 45 steel, and their structure is optimized to reduce weight while maintaining strength (overall equipment weight ≤ 150 kg). The upper plate has four through holes to reduce weight during maintenance. The upper surface of the upper plate has anti-slip patterns to prevent the yarn spool from slipping. The upper plate has a T-shaped structure, with a lower section... A hole and keyway extending axially along the intermediate connecting rod, the hole and keyway communicating, the upper part of the intermediate connecting rod being inserted into the hole of the upper plate, a key being inserted into the keyway and fastened with bolts; this allows for maintenance operations to be performed by a single person when replacing components such as pulleys or bearings; it should be noted that the inventive point of this utility model is not this, other ways to achieve a fixed connection between the upper plate and the upper part of the intermediate connecting rod are also within the protection scope of this utility model, and those skilled in the art can reasonably select other existing connection methods to achieve a mechanical connection between the upper plate and the upper part of the intermediate connecting rod according to the actual situation; the middle part of the intermediate connecting rod is stepped, composed of two cylinders of different sizes, the diameters of the two cylinders being larger than the diameters of the upper and lower parts of the intermediate connecting rod, the middle part of the intermediate connecting rod being located between the second pulley and the lower bottom surface of the first bearing, the lower part of the intermediate connecting rod being inserted sequentially from top to bottom into the second bearing I, the first positioning sleeve, the second bearing II, the third bearing, the fourth bearing and the second positioning sleeve.

[0018] As described above, in an automated rotary wire winding device, the intermediate sleeve is a stepped cylindrical structure composed of three coaxial cylinders, the diameter of which decreases sequentially from top to bottom. A through hole extending from top to bottom is provided in the fixed bearing assembly for inserting the lower part of the intermediate connecting rod. The interior of the fixed bearing assembly has a first annular groove, a second annular groove, a third annular groove, and a fourth annular groove, coaxial with the through hole, sequentially formed from top to bottom. The first bearing is located in the first annular groove, the second bearing I, the positioning sleeve I, and the second bearing II are located in the second annular groove, the third bearing is located in the third annular groove, and the fourth bearing is located in the fourth annular groove. The outer part of the positioning sleeve II is fitted into the base. The first and second annular grooves are located in the intermediate sleeve, and the third and fourth annular grooves are located in the base sleeve. The central cylinder of the intermediate sleeve is fitted into the intermediate support disc.

[0019] The first bearing and the fourth bearing are planar bearings.

[0020] In this utility model, the anti-rotation design of the intermediate sleeve is as follows:

[0021] ① The dual function of the top planar bearing: The planar bearing (i.e., the first bearing, model 51112) installed on the top of the intermediate sleeve has its lower plane in contact with the intermediate sleeve. Due to the large pressure and friction, this part will not rotate; while the upper plane of the planar bearing is in contact with the intermediate connecting rod and can rotate freely.

[0022] ② Isolation function of internal double bearings: Two ordinary bearings (model 6208) are installed inside the intermediate sleeve. The outer rings of these two bearings are firmly fixed in the intermediate sleeve, while the inner rings rotate with the intermediate connecting rod. It is equivalent to the intermediate sleeve being fixed by the "outer shell" of the bearings. The rotation of the intermediate connecting rod only drives the "inner core" of the bearings, thereby effectively suppressing most of the bidirectional radial offset and axial movement during the rotation of the intermediate connecting rod, ensuring the stability of the rotation axis.

[0023] ③ Weight-based anti-rotation: The intermediate sleeve is also supported by a large disc connected by bolts. This disc itself does not rotate, but presses down on the intermediate sleeve like a large rock, making it less likely to be rotated.

[0024] The anti-rotation principle of the base sleeve is as follows:

[0025] ①Division of labor between the inner and outer parts of the bearing: A bearing (model 6008) is installed inside the base sleeve. Its outer ring is fixed inside the base sleeve and does not move, while the inner ring can rotate with the internal parts. In this way, the rotational force is "confined" inside the bearing and cannot be transmitted to the base sleeve.

[0026] ② Separation of the bottom planar bearing: A planar bearing (i.e., the fourth bearing, model 51108) is also installed at the bottom of the base sleeve. The upper surface of this bearing is in contact with the base sleeve and does not rotate due to pressure and friction, while the lower surface is in contact with the positioning sleeve and rotates.

[0027] Furthermore, the entire base is directly bolted to the base sleeve, without contacting the rotating intermediate connecting rod. Since the base sleeve is locked in place by the above design, the base will naturally not rotate, thus ensuring stability during high-speed rotation.

[0028] As described above, in an automated rotary wire winding device, the upper and lower end faces of the positioning sleeve are stepped end faces. The positioning sleeve 1 forms axial limiting by engaging with the outer rings of the second bearing I and the second bearing II through the two stepped end faces respectively.

[0029] As described above, in an automated rotary wire take-up device, the lower cylindrical part of the intermediate sleeve is fitted into the base sleeve; the second positioning sleeve limits the fourth bearing; the second positioning sleeve is fixed by a locking nut located below it; the structure of the second positioning sleeve and the fourth bearing ensures that when the specified preload torque is reached, both assembly gaps can be eliminated and rotational resistance caused by over-constraint can be avoided, achieving a dynamic balance between reliable locking and smooth rotation.

[0030] As described above, in an automated rotary wire winding device, the intermediate support disc is radially rigidly connected to the central cylinder of the intermediate sleeve via bolts, the lower cylinder of the intermediate sleeve is radially rigidly connected to the base sleeve via bolts, and the base sleeve is axially rigidly connected to the base via bolts to ensure load-bearing stability (≥100kg); the bottom of the base has pre-drilled mounting holes for easy device fixing.

[0031] In the automated rotary wire winding device described above, the belt is a V-belt.

[0032] Beneficial effects:

[0033] (1) This utility model can realize automatic uniform yarn laying and continuous high-speed yarn winding after spinning and feeding, reduce the breakage rate caused by interlayer gaps and improve production efficiency and quality.

[0034] (2) The equipment of this utility model is compact in size and small in volume, and can be quickly moved to the production line where it is needed for production. No new equipment needs to be installed. It can be used as soon as it is moved. The geared motor is equipped with a speed regulator, which can support speed adjustment from 0 to 15 r / min to match the speed matching requirements of the spinning line.

[0035] (3) The load capacity of this utility model is ≥100kg and can be adapted to the continuous operation requirements of high-speed production lines. At the same time, the motor can use a 220V / 250W AC speed-regulating geared motor and save energy through belt drive, so that the overall energy consumption is reduced by 40%.

[0036] (4) This utility model can make the filament bundle fall into the filament bucket accurately through the sunflower guide wheel, and the filament bucket placed on the equipment is not easy to slip off.

[0037] (5) This utility model can achieve rotary winding by embedding the automated winding equipment into the reciprocating winding machine (remove the four square tubes on the reciprocating winding machine and then put the automated winding equipment on it). No other equipment needs to be added, and the function of the reciprocating winding machine is retained. At the same time, reciprocating winding and rotary winding can be switched at any time according to production needs. Attached Figure Description
