Description

Technical Field

[0001] The present invention relates to the technical field of winding equipment, and in particular to a high-speed winding system. Background Art

[0002] At present, with the continuous improvement of the spinning speed of spinning frames, the performance of the steel ring and wire ring system in the spinning system is also facing higher requirements.

[0003] Under existing technical conditions, the speed of the wire traveler on the steel ring is generally maintained at around 18,000 rpm. However, as the spinning speed continues to increase, the demand for higher speeds has gradually emerged. For example, in the ring spinning machine disclosed in the existing announcement No. CN103526358B, when the rotation speed of the wire ring continues to increase, the significant friction at high speed will cause the contact surface between the steel collar and the wire ring to generate a large amount of heat, which may not only cause the yarn to overheat and burn out, but also accelerate the wear of the wire ring, forcing the wire ring to be replaced frequently, which not only reduces the spinning efficiency, but also limits the further improvement of the spinning speed. Summary of the Invention

[0004] The present invention provides a high-speed winding system that can increase the yarn winding speed and solve the wear problem between the steel ring and the wire traveler. The specific solution is as follows: A high-speed winding system comprises a plurality of winding devices for winding yarns arranged linearly on a spinning frame frame, each of the winding devices comprising: a suspended steel collar consisting of an outer ring and an inner ring, the inner ring being rotatably mounted inside the outer ring; the annular gap between the inner ring and the outer ring being an air duct; a plurality of air inlet pipes being equidistantly distributed along the circumference of the outer ring, the output ends of which are connected to the air duct; filtered compressed air is injected into the air duct through the air inlet pipe, so that radial and axial air films are formed in the air duct, thereby making the inner ring in a fully suspended state and having no contact with the outer ring; a wire hook being mounted on the top end of the inner ring, for constraining the movement trajectory of the yarn passing through it.

[0005] Furthermore, it also includes a steel ring plate fixedly connected to the bottom end of the outer ring, and the steel ring plate is installed on the frame of the external spinning frame in a liftable manner to drive the suspended steel ring to reciprocate in the vertical direction.

[0006] Furthermore, a convex eave is installed on the top and bottom of the outer ring; the convex eave covers the outer side of the end of the inner ring and forms an air blower that is connected to the airway and is in an inclined state.

[0007] Furthermore, the convex rib portion on the outer side surface of the inner ring forms a concave windward surface, and the windward surface faces the output end of the air intake pipe.

[0008] Furthermore, it also includes a dragon tendon installed on the external spinning frame frame; a high-speed motor is installed on the dragon tendon; the output end of the high-speed motor is vertically upward and connected to a spindle rod, and the spindle rod is used for inserting and installing the yarn-wound bobbin; the spindle rod is arranged vertically as a whole and passes through the center of the inner ring, and the centers of the two are collinear.

[0009] Furthermore, the spindle rod is cone-shaped as a whole, and the tip thereof points in a direction away from the high-speed motor.

[0010] Furthermore, the spindle rod is made of carbon fiber composite material, the interior of the spindle rod is hollow and the top is opened.

[0011] Furthermore, the output end of the high-speed motor is connected to a drive shaft, and a slot is formed at the top of the drive shaft; a polygonal screw head is embedded in the slot; an insertion rod is installed at the bottom end of the spindle rod, and the bottom end of the insertion rod has a socket, and the inner surface of the socket is formed with a limiting surface that is adapted to the side shape of the polygonal screw head; a permanent magnet is also embedded in the socket of the insertion rod, forming a non-contact magnetic fit with the top of the polygonal screw head.

[0012] Furthermore, a sliding groove extending upward is formed on the top of the wire hook; a T-shaped rod is slidingly connected to the sliding groove, and the T-shaped rod is located in the limiting space on the wire hook; the vertical section of the T-shaped rod is covered with a tension spring, and the two ends of the tension spring respectively contact the surface of the wire hook and the horizontal section surface of the T-shaped rod.

[0013] Furthermore, a contact is installed on the top of the T-shaped rod; a switch is also installed on the wire hook, and the pressing part of the switch is located on the moving path of the contact; and a warning member electrically connected to the switch is also installed on the wire hook.

[0014] Compared with the prior art, the present invention can achieve at least the following beneficial effects: The system uses a suspended steel ring. Before the yarn is wound, an air pump injects air into the airway at a constant flow rate through the air inlet pipe. The inner ring is lifted by the circulating compressed gas, forming a non-contact suspension state within the outer ring. Subsequently, the bobbin is rotated at high speed by an external drive to wind the yarn onto the bobbin. During the winding process, the yarn drives the wire hook and the inner ring to rotate at high speed. At this time, the suspended inner ring does not touch the outer ring, thus eliminating the problem of wear. That is, by establishing a mechanical friction-free structure for the yarn winding process, the original contact friction motion in the yarn winding process is changed to the existing friction-free motion, thereby increasing the yarn winding and spinning speed. The rotation speed can reach 50,000 rpm, greatly improving the output and yarn quality. At the same time, this design reduces the replacement of the original friction consumables and frequent machine repairs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Please refer to Figure 1 As shown, the present invention provides a high-speed winding system, comprising a plurality of winding devices for winding yarns arranged linearly on a spinning frame frame; Figure 2 and Figure 4 As shown, each winding device includes: a suspended steel ring 200, which is composed of an outer ring 201 and an inner ring 202. The outer ring 201 adopts a split design that can be detached from top to bottom (not shown in the figure), so that the inner ring 202 with side ribs can be installed on or removed from the outer ring 201; wherein, the inner ring 202 with ribs is rotatably installed inside the outer ring 201, and at the same time prevents the inner ring 202 from being separated from the outer ring 201; the annular gap between the inner ring 202 and the outer ring 201 is an air channel 203; the air inlet pipe 204 is connected to an external air supply device (such as an air pump, not shown in the figure, which is a well-known technology and will not be described in detail) through a hose, and the air inlet pipe 204 is connected to an external air supply device (such as an air pump, not shown in the figure, which is a well-known technology and will not be described in detail) along the outer ring 2 There are multiple rings 201 distributed equidistantly around the circumference, and their output ends are connected to the air channel 203. The external air pump is in operation to continuously draw in air filtered by the external filter device and continuously output it from its output end. The output air is continuously injected into the air channel 203 from the air inlet pipe 204 and continuously discharged above and below the inner ring 202 / outer ring 201. The continuously circulating gas forms radial and axial air films in the air channel 203, so that the inner ring 202 is in a fully suspended state and has no contact with the outer ring 201. A wire hook 205 is fixedly or detachably installed on the top of the inner ring 202 to constrain the movement trajectory of the yarn passing through its internal limited space. It should be added that the filtered compressed air can prevent impurities in the air from clogging the air passage 203 and at the same time prevent the impurities from causing friction interference with the high-speed rotation of the inner ring 202; When using: Figure 3 and Figure 4 As shown, before the yarn is wound, the air pump injects air into the air channel 203 through the air inlet pipe 204 at a constant flow rate. The inner ring 202 is lifted by the circulating compressed gas, so that the inner ring 202 forms a non-contact suspension state within the outer ring 201; Then, if Figure 1 As shown, the bobbin is rotated at high speed by an external drive to wind the yarn onto the bobbin. During the winding process, the yarn drives the wire hook 205 and the inner ring 202 to rotate at high speed. At this time, the suspended inner ring 202 does not contact the outer ring 201. Therefore, during the high-speed rotation process, the inner ring 202 will not be worn due to contact with the outer ring 201. In other words, by establishing a mechanical friction-free structure for the yarn winding process, the original contact friction motion in the yarn winding process is changed to the existing friction-free motion, thereby increasing the yarn winding and spinning speed. The rotation speed can reach 50,000 rpm, greatly improving the output and yarn quality. At the same time, this design reduces the replacement of the original friction consumables (such as wire rings, rings, spindles, spindle tapes), and reduces the work of machine maintenance (such as spindle oiling and spindle tape replacement, etc.).

[0029] Reference Figure 1 、 Figure 2 and Figure 3 As shown, it also includes a steel ring plate 206 fixed to the bottom end of the outer ring 201. The steel ring plate 206 can be installed on the frame of the external spinning frame in a liftable manner to drive the suspended steel ring 200 and the wire hook 205 thereon to reciprocate in the vertical direction. It should be added that the component for realizing the lifting movement of the steel ring plate 206 here can be: direct drive by an electric push rod or a combined drive of a reciprocating screw rod and a slider. The overall effect achieved is the same as that of the prior art, which is to realize the vertical reciprocating lifting of the wire hook 205 to achieve the yarn restricted by the wire hook 205 to reciprocate along the length direction of the bobbin (vertical direction) and be wound layer by layer.

[0030] Reference Figure 4 、 Figure 5 and Figure 6 As shown, a convex eave 2011 is installed on the top and bottom of the outer ring 201; the convex eave 2011 covers the outer side of the end of the inner ring 202, and the surfaces facing the convex eave 2011 and the inner ring 202 are both inclined. An inclined air blast port 2012 is formed between the two inclined surfaces and is connected to the air duct 203. During operation: the gas injected by the above-mentioned air inlet pipe 204 will be continuously discharged from the blast port 2012 after flowing through the air duct 203, and the inclined design of the blast port 2012 allows the discharged gas to be continuously blown onto the bobbin on the spindle rod 102, and the blast port 2012 is arranged on the suspended steel collar 200 (on the inner ring 202) which can be reciprocated and lifted, so as to form dynamic impurity removal (impurities here include dust, fiber, fluff, etc.) on the surface of the yarn wound on the bobbin, so that the surface of the yarn wound layer by layer is clean, which significantly improves the cleanliness of the yarn and the quality of the yarn winding.

[0031] Reference Figure 4As shown, the convex rib portion of the outer side surface of the inner ring 202 is formed with a concave windward surface 2021, and the windward surface 2021 is opposite to the output outlet of the air inlet pipe 204 to increase the contact area between the side surface of the inner ring 202 and the gas introduced by the air inlet pipe 204. On the one hand, it ensures the central suspension stability of the inner ring 202; on the other hand, it also maintains the coaxiality between the inner ring 202, the outer ring 201, and the middle yarn tube, thereby improving the suspension stability of the inner ring 202 and ensuring the guiding accuracy of the wire hook 205 on the inner ring 202 in a stable state and the quality of the yarn winding.

[0032] Reference Figure 2 and Figure 5 As shown, it also includes a dragon bar 100 fixedly mounted on the external spinning frame frame by screws; a high-speed motor 101 is mounted on the dragon bar 100, which can adopt a high-speed permanent magnet synchronous motor in the prior art; the output end of the high-speed motor 101 is vertically upward and connected to a spindle rod 102, which is used to insert and install a bobbin for winding yarn, so that the bobbin can be installed on the spindle rod 102 and the yarn is wound; the spindle rod 102 is arranged vertically as a whole and passes through the center of the inner ring 202, and the centers of the two are collinear; During operation: by adding the high-speed motor 101, high-speed rotation power is provided for the spindle rod 102 and the bobbin thereon to rotate, so that the bobbin can wind the yarn at a high speed.

[0033] Reference Figure 2 and Figure 3 As shown, the spindle rod 102 is tapered as a whole, and the tip points away from the high-speed motor 101; this design facilitates the insertion and installation of a bobbin of the same shape made of ABS plastic, while also allowing the conical bobbin to have a certain inclination and have the following four advantages: improving the winding density and mechanical stability, tightly winding, optimizing the yarn tension control, facilitating high-speed unwinding in subsequent processes, and ensuring the quality of the yarn.

[0034] Reference Figure 3 As shown, the spindle rod 102 is made of carbon fiber composite material, which reduces the overall weight and solves the strength and inertia problems caused by the material after high-speed operation. At the same time, the interior of the spindle rod 102 is hollow and the top is opened. Compared with the solid spindle rod 102 in the prior art, the solid spindle rod 102 will have internal unevenness during the manufacturing process, and vibration will occur when the speed is high, and the speed cannot be increased. The hollow spindle rod 102 is easier to manufacture, lighter, and has a smaller moment of inertia.

[0035] Reference Figure 6 、 Figure 7 、 Figure 3 and Figure 8As shown, the output end of the high-speed motor 101 is connected to a drive shaft 1011, and a slot 1012 is formed on the top of the drive shaft 1011; a polygonal screw head 1013 is embedded in the slot 1012, such as a hexagonal screw made of metal, and its threaded portion is threadedly connected to the drive shaft 1011; an insertion rod 1021 is fixedly installed at the bottom end of the spindle rod 102, and the bottom end of the insertion rod 1021 has a socket, and the inner surface of the socket is formed with a polygonal limiting surface that is adapted to the side shape of the polygonal screw head 1013; that is, when the operator vertically installs the spindle rod 102, The spindle rod 102 can drive the insertion rod 1021 to be inserted into the slot 1012, and the socket limiting surface of the insertion rod 1021 and the side surface of the polygonal screw head 1013 form a limit, thereby completing the installation of the spindle rod 102 on the drive shaft 1011. At this time, the rotation of the high-speed motor 101 can drive the spindle rod 102 to rotate at high speed through the cooperation and connection of the above structure; on the one hand, the spindle rod 102 is connected to the high-speed motor 101, and on the other hand, it is convenient for the spindle rod 102 to be disassembled or installed on the drive shaft 1011 of the high-speed motor 101; At the same time, a permanent magnet 1022 is embedded in the socket of the insertion rod 1021, which forms a non-contact magnetic attraction with the top of the polygonal screw head 1013, so that the permanent magnet 1022 on the spindle rod 102 can be attracted in the direction of the polygonal screw head 1013 on the drive shaft 1011, thereby improving the connection effect after the two are plugged in. In addition to the above-mentioned convenience of disassembly or installation, the flexible connection between the two will offset part of the axial jitter of the spindle rod 102 caused by the rotational inertia, absorb part of the impact energy through the "elastic" deformation of the magnetic field, and reduce the instantaneous torque fluctuation transmitted to the spindle rod 102.

[0036] Reference Figure 2 、 Figure 9 、 Figure 10 and Figure 11 As shown, a sliding groove 2051 extending upward is formed on the top of the wire hook 205; a sliding sleeve is vertically fixed in the sliding groove 2051, and a T-shaped rod 2052 is slidingly connected in an inverted state in the sliding sleeve, so that the T-shaped rod 2052 can only slide in the vertical direction. The T-shaped rod 2052 is located in the limited space on the wire hook 205; a tension spring 2053 is sleeved on the vertical section of the T-shaped rod 2052, and the two ends of the tension spring 2053 respectively contact the surface of the wire hook 205 and the horizontal section of the T-shaped rod 2052, so that in the initial state of the tension spring 2053, the horizontal section of the T-shaped rod 2052 can contact the bottom surface of the sliding groove 2051; During operation: During the yarn winding process, the yarn is in a tensioned state, and the yarn passing through the limited space of the wire hook 205 is in contact with the horizontal section of the T-bar 2052. During the yarn winding process, the tension spring 2053 can give the yarn a certain tension to ensure the tightness of the yarn wound onto the bobbin; at the same time, the yarn tension compensation is given, so that the yarn can pull the T-bar 2052 to overcome the tension spring 2053 to form an adaptive change in the vertical direction, thereby avoiding strong pulling, tearing, and breakage during the yarn winding process.

[0037] Reference Figure 2 、 Figure 9 、 Figure 10 and Figure 11 As shown, a contact 2054 is installed at the top of the T-shaped rod 2052; a switch 2055 is also installed on the wire hook 205, and the pressing portion of the switch 2055 is located on the moving path of the contact 2054. The contact portion between the contact 2054 and the switch 2055 can be padded with rubber to reduce contact damage between the two; a warning member (not shown in the figure) electrically connected to the switch 2055 is also installed on the wire hook 205. The warning member can be a lamp bead that emits obvious light. Its own power supply is electrically connected to the switch 2055. When the switch 2055 is pressed, the lamp bead can emit light to warn; During operation: During the yarn winding process, the yarn will exert varying degrees of tension on the T-bar 2052. If the yarn breaks, the yarn passing through the wire hook 205 will no longer come into contact with the T-bar 2052, and the tension originally exerted by the yarn on the T-bar 2052 will disappear. This means that the yarn passing through the wire hook 205 is broken. Therefore, there are the following disadvantages: First, the spindle 102 or the bobbin thereon is still rotating at high speed, resulting in useless winding work (idling). Secondly, there is also a situation where the broken yarn does not pass through the wire hook 205 but directly contacts and entangles with the bobbin. In this case, the yarn wound on the bobbin forms a disordered entanglement (the yarn loses the uniform reciprocating traction of the suspension steel ring 200), resulting in the quality of the yarn wound on the bobbin not meeting the standards. In severe cases, the yarn and the suspension steel ring 200 may become entangled and cause damage to the equipment. For this reason, Figure 9 As shown, after the yarn breaks, the T-bar 2052 loses the tension of the yarn, and the T-bar 2052 moves down and resets under the action of the tension spring 2053. At this time, the T-bar 2052 will drive the contact 2054 fixed thereto to move down and reset synchronously. During the process, the contact 2054 will press on the pressing part of the switch 2055 after resetting, so that the warning part is powered on. At this time, the equipment can be shut down and the broken yarn ends and unwound yarn tubes can be processed through manual or external equipment monitoring.
