Description

Technical Field

[0001] The invention belongs to the technical field of spinning equipment, and in particular relates to a spindle assembly of a spinning winder. Background Art

[0002] The winding machine is an important textile machine. Its main function is to connect the tubes (or hanks) with smaller capacity to make larger bobbins, which is convenient for the operation of subsequent processes. The main mechanisms of the winding machine include grooved drums, rollers, winding mechanisms, transmission systems and control systems. Among them, the spindle assembly is an important part of the winding mechanism of the winding machine, which is mainly responsible for the winding and forming of the yarn. During the winding process, the yarn is wound on the bobbin through the rotation of the spindle to form a stable yarn package.

[0003] At present, the bobbin is sleeved on the spindle, and then the bobbin is contacted with the grooved drum. The driving component drives the grooved drum to rotate. The grooved drum drives the bobbin on the spindle to rotate through friction to realize the winding of the yarn. At the same time, the spiral groove of the grooved drum pulls and guides the yarn, making the yarn swing back and forth, and the yarn can be evenly wound on the bobbin.

[0004] However, the friction between the bobbin and the grooved drum is affected by the type of yarn. When the surface friction coefficient of the yarn is low, the friction is small. As the winding continues, the weight of the bobbin increases. The low friction coefficient causes the grooved drum to be unable to stably drive the bobbin to rotate, resulting in a speed difference between the grooved drum and the bobbin. The yarn continues to swing back and forth at a high speed under the traction of the grooved drum, while the winding speed of the bobbin is reduced. The yarn arrangement position on the bobbin cannot be synchronized with the traction and swing of the grooved drum, which will cause the yarn to be pulled and deformed, resulting in a decrease in the tensile strength of the yarn or even breakage. Summary of the invention

[0009] A spring box and a connecting shaft are provided on one side of the mounting seat, and both ends of the connecting shaft are respectively connected to the transmission wheel and the spring box. The elastic force of the spring box acts in a direction toward the groove roller, so that the spring box can apply an elastic thrust to the transmission wheel to move toward the groove roller, thereby maintaining the contact transmission between the conical surface and the groove roller.

[0010] Furthermore, the spring box includes a bracket and a slide plate, the bracket is fixed on the mounting seat, the slide plate is slidably connected to the bracket, the bracket is provided with a spring for applying elastic force to the slide plate, and the connecting shaft is connected to the slide plate.

[0011] Furthermore, an electromagnetic brake is provided on the skateboard, and the electromagnetic brake includes two connectable / disconnectable ends, one end of the electromagnetic brake is connected to the skateboard, and the other end of the electromagnetic brake is connected to the connecting shaft. When the two ends of the electromagnetic brake are connected, the rotational load of the transmission wheel increases, and the spindle roller and the groove roller can be braked at the same time.

[0012] Furthermore, a detection component for detecting the axial sliding speed of the transmission wheel along the spindle roller is also provided on one side of the mounting seat.

[0013] Furthermore, the detection component includes a speed sensor, and the speed sensor is fixed on the bracket.

[0014] Furthermore, the transmission wheel is composed of two mutually symmetrical semi-conical blocks, an insert plate is provided on the inner side of the semi-conical block, a slide groove corresponding to the insert plate is opened on the spindle roller, and a slot corresponding to the insert plate is opened at one end of the connecting shaft located in the spindle roller, and the insert plate is inserted into the slide groove and plugged into the slot.

[0015] Furthermore, it also includes a movable arm and a support shaft, one end of the movable arm is fixed with a shaft sleeve, the shaft sleeve is rotatably sleeved on the support shaft, and the mounting seat is connected to the other end of the movable arm.

[0016] Furthermore, a fixing ring is provided at one end of the shaft sleeve, and the fixing ring is fixed on the supporting shaft. A torsion spring is provided between the shaft sleeve and the fixing ring for applying a force to the movable arm to swing toward the groove roller.

[0017] Furthermore, the driving component includes a support seat and a motor, the motor is mounted on the support seat, and the output shaft of the motor is coaxially fixed with the grooved roller.

[0018] Furthermore, the mounting seat is provided with a shaft tube penetrating the mounting seat, the spindle roller is rotatably connected to the shaft tube via a bearing, and the connecting shaft passes through the interior of the shaft tube.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows:

[0020] 1. A transmission wheel is arranged at one end of the spindle roller, and the groove roller drives the spindle roller to rotate through the transmission wheel.

[0021] 2. An electromagnetic brake is set and one end of the connecting shaft is connected to the electromagnetic brake. When the two ends of the electromagnetic brake are connected, the friction plate inside the electromagnetic brake combines with the brake disc to generate a friction torque, which hinders the rotation of the connecting shaft and increases the rotation load of the transmission wheel connected to the connecting shaft. The transmission wheel can brake the spindle roller and the groove roller at the same time, so that the spindle roller and the groove roller decelerate and stop synchronously, which is convenient for the winding machine to re-wire and connect the wires.

[0022] 3. The axial movement speed of the transmission wheel is detected in real time through the detection component. By detecting the axial movement speed of the transmission wheel, the speed of increase of the winding diameter of the yarn on the bobbin can be known. When the axial movement speed of the transmission wheel is greater than the preset value, that is, the speed of increase of the winding diameter of the yarn on the bobbin is too fast, at this time, it can be judged that the yarn is out of the spiral groove of the groove roller, and the alarm is stopped in time to adjust the yarn.

[0033] 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; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0035] like Figure 1 As shown, the present invention proposes a spinning winder spindle assembly, including a spindle roller 1, a groove roller 2 and a mounting seat 4, one end of the groove roller 2 is provided with a driving component for driving the groove roller 2 to rotate, the spindle roller 1 is rotatably connected to the mounting seat 4, and a bobbin for winding is sleeved on the spindle roller 1, and the bobbin rotates to wind the yarn.

[0036] Among them, the grooved roller 2 is composed of a rotating roller with two spiral grooves in opposite directions. When the yarn is introduced onto the spindle roller 1, it passes through the spiral groove. As the grooved roller 2 rotates, the spiral groove of the grooved roller 2 pulls and guides the yarn, causing the yarn to swing back and forth, and the yarn can be evenly wound on the bobbin.

[0037] In a specific embodiment, the driving component includes a support seat 21 and a motor 22. The motor 22 is installed on the support seat 21. The output shaft of the motor 22 is coaxially fixed with the groove roller 2. The support seat 21 supports the motor 22 and the groove roller 2, and the motor 22 drives the groove roller 2 to rotate.

[0038] Combination Figure 1 and Figure 2 As shown, a transmission wheel 5 is coaxially provided on the spindle roller 1, and the transmission wheel 5 is in contact with the groove roller 2. When the groove roller 2 is driven to rotate by the driving component, the groove roller 2 drives the spindle roller 1 to rotate through the transmission wheel 5, thereby causing the bobbin on the spindle roller 1 to rotate and wind the yarn.

[0039] As the bobbin continues to wind the yarn, the yarn winding diameter on the bobbin gradually increases, causing the distance between the spindle roller 1 and the groove roller 2 to gradually increase.

[0040] The driving wheel 5 is configured to be able to slide along the axial direction of the spindle roller 1. The driving wheel 5 is provided with a conical surface 501 that can adapt to the change in the spacing between the spindle roller 1 and the groove roller 2. A spring box and a connecting shaft 9 are provided on one side of the mounting seat 4. Both ends of the connecting shaft 9 are respectively connected to the driving wheel 5 and the spring box. The elastic force of the spring box acts in a direction toward the groove roller 2, so that the spring box can apply an elastic thrust to the driving wheel 5 to move toward the groove roller 2.

[0041] When the distance between the spindle roller 1 and the groove roller 2 gradually increases, the transmission wheel 5 is pushed toward the groove roller 2, so that the conical surface 501 can gradually contact the groove roller 2 from the small end to the large end, maintaining the transmission between the spindle roller 1 and the groove roller 2;

[0042] Furthermore, the diameter of the smallest end of the conical surface 501 is consistent with the outer diameter of the bobbin mounted on the spindle roller 1. At the initial startup, the grooved roller 2 and the outer wall of the bobbin maintain the same linear speed. As the yarn winding diameter on the bobbin increases, the diameter of the contact area between the conical surface 501 and the grooved roller 2 is always consistent with the yarn winding diameter on the bobbin to keep the linear speed consistent.

[0043] In a specific embodiment, the spring box always applies pressure to the transmission wheel 5 so that the conical surface 501 of the transmission wheel 5 is always pressed against the groove roller 2. Under the action of pressure, sufficient transmission friction is maintained between the transmission wheel 5 and the groove roller 2, so that the transmission between the transmission wheel 5 and the groove roller 2 is not affected by the weight of the bobbin winding.

[0044] Furthermore, the driving wheel 5 is made of a material with a large surface friction coefficient, which further increases the friction between the driving wheel 5 and the groove roller 2 and avoids the groove roller 2 and the driving wheel 5 from slipping.

[0045] In this way, when winding, the empty bobbin is sleeved on the spindle roller 1, and the smallest diameter end of the conical surface 501 on the driving wheel 5 contacts the groove roller 2. The driving component drives the groove roller 2 to rotate, and the groove roller 2 drives the spindle roller 1 to rotate through the driving wheel 5 to wind the yarn. As the bobbin continues to wind the yarn, the winding diameter of the yarn on the bobbin gradually increases, causing the distance between the spindle roller 1 and the groove roller 2 to gradually increase. The spring box pushes the driving wheel 5 to move and pushes the driving wheel 5 toward the direction close to the groove roller 2, so that the conical surface 501 can gradually contact the groove roller 2 from the small end to the large end, maintaining the transmission between the spindle roller 1 and the groove roller 2;

[0046] The transmission wheel 5 is used for transmission between the spindle roller 1 and the groove roller 2, so that the transmission between the spindle roller 1 and the groove roller 2 is not affected by the friction coefficient of the yarn, avoiding the speed difference due to slipping. At the same time, the spring box always applies pressure to the transmission wheel 5, so that the conical surface 501 of the transmission wheel 5 is always pressed on the groove roller 2. Under the action of pressure, sufficient transmission friction is maintained between the transmission wheel 5 and the groove roller 2.

[0047] Furthermore, the end surfaces of the grooved roller 2 and the driving wheel 5 corresponding to one another are provided with friction cone surfaces 201 , and the friction cone surfaces 201 and the conical surfaces 501 correspond to each other, thereby increasing the contact area between the driving wheel 5 and the grooved roller 2 .

[0048] In an optional embodiment, the transmission wheel 5 is made of polyurethane rubber, which has a high surface friction coefficient and has high hardness and wear resistance.

[0049] Furthermore, the friction between the conical surface 501 and the grooved roller 2 can be further increased by providing anti-skid grooves on the conical surface 501 of the driving wheel 5 .

[0050] Combination Figure 2 and Figure 3 As shown, the mounting seat 4 is provided with a shaft tube 41 which passes through the mounting seat 4, the spindle roller 1 is rotatably connected to the shaft tube 41 through a bearing, and the connecting shaft 9 passes through the inside of the shaft tube 41 and connects the transmission wheel 5 and the spring box.

[0051] In a specific embodiment, the spring box includes a bracket 6 and a slide plate 7, the bracket 6 is fixed on the mounting base 4, the slide plate 7 is slidably connected to the bracket 6, a spring 8 for applying elastic force to the slide plate 7 is provided on the bracket 6, and a connecting shaft 9 is connected to the slide plate 7, so that the slide plate 7 can push the transmission wheel 5 to move through the connecting shaft 9, and use the spring 8 to apply pressure to the transmission wheel 5 so that the conical surface 501 of the transmission wheel 5 is always pressed on the groove roller 2. When the distance between the spindle roller 1 and the groove roller 2 gradually increases, under the action of the spring 8, the transmission wheel 5 is pushed toward the direction close to the groove roller 2, so that the conical surface 501 can gradually contact the groove roller 2 from the small end to the large end, thereby maintaining the transmission between the spindle roller 1 and the groove roller 2.

[0052] Furthermore, an electromagnetic brake 71 is provided on the slide plate 7 . The electromagnetic brake 71 includes two connectable / disconnectable ends. One end of the electromagnetic brake 71 is connected to the slide plate 7 , and the other end of the electromagnetic brake 71 is rotatably connected to the connecting shaft 9 .

[0053] When the two ends of the electromagnetic brake 71 are in the disconnected state, the connecting shaft 9 can rotate freely without affecting the driving wheel 5. When the two ends of the electromagnetic brake 71 are connected, the friction plate inside the electromagnetic brake 71 combines with the brake disc to generate a friction torque, which hinders the rotation of the connecting shaft 9 and increases the rotation load of the driving wheel 5 connected to the connecting shaft 9. The driving wheel 5 can brake the spindle roller 1 and the groove roller 2 at the same time, so that the spindle roller 1 and the groove roller 2 slow down and stop synchronously, which is convenient for the winding machine to re-wire and connect the wires.

[0054] Combination Figure 4 , Figure 5 and Figure 6 As shown, the transmission wheel 5 is composed of two mutually symmetrical semi-conical blocks 51, a plug plate 52 is arranged on the inner side of the semi-conical block 51, a slide groove 101 corresponding to the plug plate 52 is opened on the spindle roller 1, and a slot 901 corresponding to the plug plate 52 is opened at one end of the connecting shaft 9 located in the spindle roller 1, and the plug plate 52 is inserted into the slide groove 101 and plugged into the slot 901;

[0055] Furthermore, the length of the slot 901 is the same as the cross-sectional length of the plug plate 52. After the plug plate 52 is inserted into the slot 901, it cannot slide in the slot 901, so that when the connecting shaft 9 pushes the transmission wheel 5 to move axially, the transmission wheel 5 can move axially synchronously with the connecting shaft 9.

[0056] Furthermore, the length of the slide groove 101 is greater than the cross-sectional length of the inserting plate 52 , so that the inserting plate 52 can slide in the slide groove 101 .

[0057] In this way, the plug plate 52 acts as a key, and the slide groove 101 and the slot 901 act as key grooves. By utilizing the cooperation between the plug plate 52 and the slide groove 101, the transmission wheel 5 can drive the spindle roller 1 and the connecting shaft 9 to rotate synchronously. Since the length of the slide groove 101 is greater than the cross-sectional length of the plug plate 52, the plug plate 52 can slide in the slide groove 101, so that the connecting shaft 9 pushes the transmission wheel 5 to slide through the plug plate 52.

[0058] In a specific embodiment, the end faces of the two semi-conical blocks 51 are provided with corresponding connecting seats 53 , and bolts are used to penetrate the two corresponding connecting seats 53 , and then nuts are used to tighten them, so as to fix the two semi-conical blocks 51 .

[0059] Combination Figure 2 and Figure 3 As shown, a detection component for detecting the axial sliding speed of the transmission wheel 5 along the spindle roller 1 is also provided on one side of the mounting seat 4;

[0060] As the bobbin continues to wind the yarn, the yarn winding diameter on the bobbin gradually increases, causing the distance between the spindle roller 1 and the groove roller 2 to gradually increase. As the distance increases, the transmission wheel 5 is gradually pushed toward the groove roller 2. Therefore, the speed at which the yarn winding diameter increases is proportional to the axial movement speed of the transmission wheel 5, that is, the faster the yarn winding diameter increases, the faster the axial movement speed of the transmission wheel 5.

[0061] Therefore, by detecting the axial movement speed of the transmission wheel 5, the increasing speed of the yarn winding diameter on the bobbin can be known. When the yarn is normally guided by the groove roller 2 and evenly wound on the bobbin, the speed of increasing the yarn winding diameter is relatively slow, and accordingly, the axial movement speed of the transmission wheel 5 is also slow. When the yarn breaks away from the spiral groove of the groove roller 2, the yarn is no longer guided by the groove roller 2 to be evenly wound, but is concentratedly wound at one place of the bobbin. At this time, the speed of increasing the yarn winding diameter is relatively fast, and accordingly, the axial movement speed of the transmission wheel 5 is also relatively fast.

[0062] In this way, by detecting the axial movement speed of the transmission wheel 5 in real time through the detection component, the speed of increasing the winding diameter of the yarn on the bobbin can be known. When the axial movement of the transmission wheel 5 is too fast, the speed of increasing the winding diameter of the yarn on the bobbin is also faster. At this time, it can be judged that the yarn has detached from the spiral groove of the groove roller 2, and the alarm can be stopped in time to adjust the yarn.

[0063] It should be noted that since the yarn winding speed is affected by the rotation speed of the grooved roller 2, the normal axial movement speed of the transmission wheel 5 at different rotation speeds of the grooved roller 2 is preset in the equipment control unit. When the axial movement speed of the transmission wheel 5 is greater than the normal movement speed preset in the control unit, an alarm is triggered and the machine is shut down.

[0064] Furthermore, the detection component includes a speed sensor 61, which is installed on the bracket 6. Since the skateboard 7 and the transmission wheel 5 are respectively connected to the two ends of the connecting shaft 9, the skateboard 7 and the transmission wheel 5 move synchronously. Therefore, the speed sensor 61 can measure the axial movement speed of the transmission wheel 5 by detecting the speed of the skateboard 7.

[0065] Combination Figure 1 As shown, the present invention also includes a movable arm 3 and a support shaft 100, a sleeve 31 is fixed to one end of the movable arm 3, the sleeve 31 is rotatably sleeved on the support shaft 100, and a mounting seat 4 is connected to the other end of the movable arm 3;

[0066] The spindle roller 1 is supported by the movable arm 3. As the winding diameter of the bobbin on the spindle roller 1 increases, the movable arm 3 swings upward with the support shaft 100 as the rotation axis.

[0067] Furthermore, a fixing ring 32 is provided at one end of the sleeve 31, and the fixing ring 32 is fixed on the support shaft 100. A torsion spring 33 is provided between the sleeve 31 and the fixing ring 32. The torsion spring 33 can exert a force on the movable arm 3 to swing toward the groove roller 2, so that the spindle roller 1 can move away from the groove roller 2 only when the winding diameter of the bobbin increases, thereby preventing the spring 8 from exerting a thrust on the transmission wheel 5 to push the spindle roller 1 upward.

[0068] It should be understood that the support shaft 100 is installed on the winding machine and is shared by multiple workstations.

[0069] In summary of the above embodiments: a transmission wheel 5 is arranged at one end of the spindle roller 1, and the groove roller 2 drives the spindle roller 1 to rotate through the transmission wheel 5. A conical surface 501 is provided on the transmission wheel 5, which can adapt to the change of the spacing between the spindle roller 1 and the groove roller 2, and the transmission wheel 5 is arranged to be able to slide along the axial direction of the spindle roller 1, so that the conical surface 501 can gradually contact with the groove roller 2 from the small end to the large end, maintain the transmission between the spindle roller 1 and the groove roller 2, so that the transmission between the spindle roller 1 and the groove roller 2 is not affected by the friction coefficient of the yarn, and at the same time, the spring box always applies pressure to the transmission wheel 5, so that the conical surface 501 of the transmission wheel 5 is always pressed on the groove roller 2, and under the action of pressure, sufficient transmission friction is maintained between the transmission wheel 5 and the groove roller 2 to avoid the phenomenon of speed difference due to slipping.

[0070] By setting the electromagnetic brake 71 and connecting one end of the connecting shaft 9 to the electromagnetic brake 71, when the two ends of the electromagnetic brake 71 are connected, the friction plate inside the electromagnetic brake 71 combines with the brake disc to generate a friction torque, so that the rotation of the connecting shaft 9 is hindered, and the rotation load of the transmission wheel 5 connected to the connecting shaft 9 is increased. The transmission wheel 5 can brake the spindle roller 1 and the groove roller 2 at the same time, so that the spindle roller 1 and the groove roller 2 are synchronously decelerated and stopped, which is convenient for the winding machine to re-wire and connect the wires.

[0071] By detecting the axial movement speed of the transmission wheel 5 in real time through the detection component, the speed of increasing the winding diameter of the yarn on the bobbin can be known. When the axial movement speed of the transmission wheel 5 is greater than the preset value, that is, the speed of increasing the winding diameter of the yarn on the bobbin is too fast, at this time, it can be judged that the yarn has deviated from the spiral groove of the groove roller 2, and the alarm is promptly sounded to stop the machine and adjust the yarn.
