Abstract
Description
Technical Field
[0001] This invention relates to the field of twisting machine technology, and more specifically to a double-twisting energy-saving spindle device. Background Technology
[0002] Two-twisting machines offer high twisting efficiency, large package size, fewer knots, and reduced labor costs, minimizing winding processes. Their application is becoming increasingly widespread, particularly suitable for high-speed sewing threads with fewer knots, high-count, high-end garment fabrics, high-performance fiber products, and for use with high-speed shuttleless looms. However, compared to conventional twisting, two-twisting machines consume more energy.
[0003] Twisting machines rely on a belt to frictionally drive the spindle for twisting. However, the belt itself is elastic, and its tension is significantly affected by weather. In autumn and winter, the belt contracts, increasing tension and thus spindle speed; conversely, in spring and summer, the opposite occurs, leading to uneven twist. Existing technologies generally increase the friction between the belt and the spindle by adjusting the center distance or intervening with the tensioner to maintain spindle speed balance. However, existing technologies suffer from the following technical problems: First, adjusting the center distance and the method of intervention by the tensioner pulley will both cause changes in the transmission wrap angle of the drive spindle. For example, reducing the preload applied by the tensioner pulley to the belt will result in a smaller wrap angle, while increasing the preload applied by the tensioner pulley to the belt will result in a larger wrap angle. According to the design requirements of the transmission ratio of the twisting machine, the motor achieves high-speed rotation of the spindle through friction transmission of the belt. Experimental data shows that when the wrap angle deviation is ±5°, the radial amplitude increases, causing the belt to vibrate under the action of centrifugal force.
[0004] Second, according to the design requirements of the transmission ratio of the twisting machine, the motor realizes the high-speed rotation of the spindle through the friction transmission of the belt. At this time, the frictional heat generated between the belt and the spindle disc increases significantly, the surface temperature of the belt continues to rise, and the friction coefficient of the belt decreases due to the softening of the belt at high temperature.
[0005] Third, twisting machines are prone to producing thread ends during operation. If these thread ends are attached to the belt, they will change the contact state between the belt and the pulley, causing local slippage or tension fluctuations. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a double-twist energy-saving spindle device.
[0007] The objective of this invention can be achieved through the following technical solutions: A twisting energy-saving spindle device includes a housing, on which a twisting component is installed. The twisting component includes a spindle body, a twisting disc, and a yarn separator disc. The twisting disc is fixedly installed on the top of the spindle body, and the yarn separator disc is fixed to the top of the upper twisting disc and formed as a whole by screws. A power assembly is installed inside the housing, which drives the spindle body to rotate via a belt. A stabilizing component and a tensioning wheel are installed on the housing, and the stabilizing component and the tensioning wheel are driven by the drive assembly. The stabilizing component includes a fixed platform, with a gear disc rotatably installed at the bottom of the fixed platform. An inner fixed roller and an outer fixed roller are slidably installed inside the fixed platform, and the belt clamps the inner fixed roller and the outer fixed roller. Between the outer fixed rollers; the drive assembly includes a second motor installed inside the housing, the output end of the second motor connected to a lead screw, the lead screw being connected to a guide block for transmission, the guide block being slidably installed inside the housing, an L-shaped rack and a connecting rod respectively installed on the side wall of the guide block, the L-shaped rack meshing with a gear disc, the connecting rod connecting to a roller sleeve, a tension wheel installed on the roller sleeve, the tension wheel being in contact with the outer wall of the belt; a cooling and cleaning assembly is installed on the inner and outer fixed rollers, the inner and outer fixed rollers are connected to the cooling and cleaning assembly, the inner and outer fixed rollers are provided with a liquid inlet at the top and a liquid outlet at the bottom, the liquid inlet and liquid outlet being connected to a liquid cooling system.
[0008] As a further aspect of the present invention: a sliding groove is provided on the box body, and the roller sleeve slides inside the sliding groove.
[0009] As a further embodiment of the present invention: a fixing sleeve is installed at the bottom of the box, and a fixing platform is located inside the fixing sleeve and rotates. A sliding cavity is symmetrically opened on the fixing platform, and an inner fixed roller and an outer fixed roller are respectively installed in the sliding cavity. A top block is slidably installed inside the sliding cavity, and the top block is respectively attached to the inner fixed roller and the outer fixed roller. An inner convex ring is opened on the inner wall of the fixing sleeve. When the fixing platform rotates, the top block cooperates with the inner convex ring.
[0010] As a further aspect of the present invention, a rubber pad is installed between the inner fixed roller and the sliding cavity on one side and between the outer fixed roller and the sliding cavity on the other side.
[0011] As a further aspect of the present invention: the cooling and cleaning assembly includes a sleeve rotatably mounted on the inner fixed roller and the outer fixed roller, a plurality of cooling pipes are installed between the sleeves, and cooling ports are provided at the top and bottom of the sleeves. The cooling ports are connected to the cooling pipes and are also connected to the liquid inlet and outlet of the inner fixed roller.
[0012] As a further aspect of the present invention: a baffle is installed on the cooling pipe to divide the gaps between the cooling pipes into several adsorption chambers. A fiber board is installed on the side of the baffle near the inner fixed roller, and a fiber sleeve is installed on the inner fixed roller. Static electricity is generated by the friction between the fiber board and the fiber sleeve to adsorb the yarn on the belt. A bearing is installed on the outer wall of the sleeve, and the belt is attached to the bearing.
[0013] As a further aspect of the present invention: the power assembly includes a motor installed inside the housing, the output end of the motor being connected to a drive wheel, and the drive wheel driving the spindle body to rotate via a belt.
[0014] As a further aspect of the present invention: the twisting component further includes a liner tensioner and a yarn supply bobbin, wherein the fixing tube of the liner tensioner is disposed in the central inner hole of the yarn supply bobbin and communicates with and cooperates with the twisting disc; the outer shell of the twisting component is made of aluminum-magnesium alloy material.
[0015] The beneficial effects of this invention are: (1) The present invention delivers coolant through the top inlet of the inner fixed roller and the outer fixed roller. The coolant enters the cooling pipe through the cooling port to dissipate heat on both sides of the belt between the outer fixed roller and the inner fixed roller. Finally, the coolant is discharged through the bottom outlet of the inner fixed roller and the outer fixed roller.
[0016] When belt tensioning is required, motor two drives the lead screw to rotate, which is connected to the guide block via a transmission. The guide block moves closer to motor two, and at this time, the guide block drives the roller sleeve and tension wheel to move closer to each other along the slide groove via a connecting rod. The tension wheel is used to adjust the belt tension. During this process, the belt is clamped in the middle by the inner and outer fixed rollers, fixing the contact area between the belt and the spindle body, i.e., fixing the wrap angle, limiting the lateral displacement of the belt, and preventing belt vibration caused by high-speed centrifugal force.
[0017] (2) When the motor two drive guide block of the present invention moves close to the motor two direction, the L-shaped rack on the guide block drives the toothed disc to rotate, and the toothed disc drives the fixed table to rotate synchronously. When the fixed table rotates, the top block presses the outer fixed roller by cooperating with the inner convex ring, so that the outer fixed roller is in contact with the back of the belt. At this time, the inner fixed roller and the outer fixed roller clamp the belt again, which promotes uniform heat dissipation on the front and back of the belt, and avoids the temperature difference between the front and back of the belt, which leads to accelerated fatigue of the belt material.
[0018] (3) As the tensioning wheel applies pre-tension to the belt, the belt is stretched and its thickness is reduced, making it more prone to vibration during high-speed operation. Therefore, the present invention drives the inner and outer fixed rollers to rotate through the fixed platform. As the inner and outer fixed rollers rotate, the contact area between the inner and outer fixed rollers and the belt increases, thereby improving the ability of the inner and outer fixed rollers to suppress the belt and preventing the belt from vibrating at high speed due to the reduction in belt thickness.
[0019] (4) When the duct belt of the present invention adsorbs the thread ends and debris, the thickness of the duct belt increases. When the duct belt passes through the sleeve, the duct belt contacts the sleeve, causing the duct belt to drive the sleeve to rotate. When the sleeve rotates, the fiberboard and the fiber sleeve rub against each other to generate static electricity. The thread ends on the duct belt are sucked into the adsorption cavity under the action of static electricity, thus avoiding local slippage or tension fluctuation of the duct belt.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Please see Figures 1-9 As shown, this invention is a double-twisting energy-saving spindle device, which includes a housing 1. A twisting component 2 is installed on the housing 1. The twisting component 2 includes a spindle body 205, a twisting disc 203, and a yarn separator disc 204. The twisting disc 203 is fixedly installed on the top of the spindle body 205, and the yarn separator disc 204 is fixed to the top of the upper twisting disc 203 and fixed with screws to form an integral unit. A power component 5 is installed inside the housing 1. The power component 5 drives the spindle body 205 to rotate through a belt 4. A stabilizing component 6 and a tensioning wheel 7 are installed on the housing 1, and the stabilizing component 6 and the tensioning wheel 7 are driven by a driving component 8. The stabilizing component 6 includes a fixed platform 604. A gear disc 602 is rotatably installed at the bottom of the fixed platform 604. An inner fixed roller 605 and an outer fixed roller 606 are slidably installed inside the fixed platform 604. The belt 4 is clamped between the inner fixed roller 605 and the outer fixed roller 606. Between the side fixed rollers 606; the drive assembly 8 includes a second motor 801 installed inside the housing 1, the output end of the second motor 801 is connected to a lead screw 802, the lead screw 802 is connected to a guide block 803, the guide block 803 is slidably installed inside the housing 1, an L-shaped rack 804 and a connecting rod 805 are respectively installed on the side wall of the guide block 803, the L-shaped rack 804 meshes with the gear disc 602, the connecting rod 805 is connected to a roller sleeve 806, a tension wheel 7 is installed on the roller sleeve 806, the tension wheel 7 is in contact with the outer side wall of the belt 4; a cooling and cleaning assembly 9 is installed on the inner fixed roller 605 and the outer fixed roller 606, the inner fixed roller 605 and the outer fixed roller 606 are connected to the cooling and cleaning assembly 9, the inner fixed roller 605 and the outer fixed roller 606 are provided with a liquid inlet at the top and a liquid outlet at the bottom, the liquid inlet and the liquid outlet are connected to a liquid cooling system.
[0025] Specifically, a groove 807 is formed on the housing 1, and the roller sleeve 806 slides inside the groove 807. Specifically, the power assembly 5 includes a motor 502 installed inside the housing 1, the output end of which is connected to a drive wheel 501. The drive wheel 501 drives the spindle body 205 to rotate via the belt 4. It should be noted that a protective plate 3 is installed on the housing 1 to protect the belt 4 transmission.
[0026] It should be noted that motor 502 drives drive wheel 501 to rotate, and drive wheel 501 drives spindle body 205 to rotate through belt 4, causing spindle body 205 to rotate at high speed, thereby realizing twisting operation.
[0027] Twisting process: The yarn to be twisted is drawn from the yarn supply bobbin 201, passed through the top of the spindle tensioner 202 and into the hollow spindle rod inside the spindle tensioner 202, and then the yarn end is led out through the radial guide hole of the twisting disc 203. As the spindle body 205 rotates one revolution, the yarn inside the hollow spindle rod and the yarn led out from the radial guide hole of the twisting disc 203 acquire a twist.
[0028] The present invention delivers coolant through the top inlets of the inner fixed roller 605 and the outer fixed roller 606. The coolant enters the cooling pipe 904 through the cooling port 902 to dissipate heat on both sides of the belt 4 between the outer fixed roller 606 and the inner fixed roller 605. Finally, the coolant is discharged through the bottom outlets of the inner fixed roller 605 and the outer fixed roller 606.
[0029] When it is necessary to tighten the belt 4, the second motor 801 drives the lead screw 802 to rotate. The lead screw 802 is connected to the guide block 803 through transmission. The guide block 803 moves closer to the second motor 801. At this time, the guide block 803 drives the roller sleeve 806 and the tension wheel 7 to move closer to each other along the slide groove 807 through the connecting rod 805. The tension wheel 7 is used to adjust the tightness of the belt 4. During this process, the inner fixed roller 605 and the outer fixed roller 606 clamp the belt 4 in the middle, fixing the contact area between the belt 4 and the spindle body 205, that is, fixing the wrap angle, limiting the lateral displacement of the belt 4, and preventing the belt 4 from vibrating under the action of high-speed centrifugal force. Moreover, the present invention further suppresses the high-speed vibration of the belt 4 by clamping the belt 4 with the inner fixed roller 605 and the outer fixed roller 606.
[0030] If it is necessary to loosen belt 4, motor 2 801 drives lead screw 802 to rotate in the opposite direction.
[0031] It should be noted that the present invention replaces the adjustment method of the tensioning wheel 7 by directly connecting the guide block 803 to the power component 5, that is, by adjusting the center distance to replace the tensioning wheel 7 for tensioning.
[0032] See Figures 6-8 A fixing sleeve 601 is installed at the bottom of the housing 1. A fixing platform 604 rotates inside the fixing sleeve 601. A sliding cavity 609 is symmetrically opened on the fixing platform 604. An inner fixed roller 605 and an outer fixed roller 606 are respectively installed in the sliding cavity 609. A top block 607 is slidably installed inside the sliding cavity 609. The top block 607 is respectively attached to the inner fixed roller 605 and the outer fixed roller 606. An inner convex ring 603 is opened on the inner wall of the fixing sleeve 601. When the fixing platform 604 rotates, the top block 607 cooperates with the inner convex ring 603.
[0033] Specifically, rubber pads 608 are installed between the inner fixed roller 605 and the sliding cavity 609 on one side, and between the outer fixed roller 606 and the sliding cavity 609 on the other side.
[0034] It should be noted that when preload is applied to the duct belt 4 via the tensioning pulley 7, the tension of the duct belt 4 increases, causing it to be stretched along its length, resulting in a corresponding decrease in its thickness to maintain a substantially constant volume. See also Figure 12 As shown, the tensioning wheel 7 applies a pre-tension force to the duct belt 4, causing the duct belt 4 to be tightly pressed against the inner fixed roller 605. Due to the reduced thickness of the duct belt 4, a gap is generated between the duct belt 4 and the outer fixed roller 606. The cooling and cleaning components 9 on the outer fixed roller 606 reduce the heat dissipation capacity of the duct belt 4, resulting in a temperature difference between the front and back of the duct belt 4. This temperature difference will accelerate material fatigue and lifespan loss.
[0035] Based on this, when the second motor 801 drives the guide block 803 to move closer to the second motor 801, the L-shaped rack 804 on the guide block 803 drives the gear disk 602 to rotate. See [link / reference] Figures 6-7 The toothed disc 602 drives the fixed platform 604 to rotate synchronously. When the fixed platform 604 rotates, the top block 607 presses the outer fixed roller 606 by cooperating with the inner convex ring 603, so that the outer fixed roller 606 is in contact with the back of the duct belt 4. At this time, the inner fixed roller 605 and the outer fixed roller 606 clamp the duct belt 4 again, which promotes uniform heat dissipation on the front and back of the duct belt 4 and avoids the temperature difference between the front and back of the duct belt 4, which would cause the material of the duct belt 4 to fatigue faster.
[0036] It should be noted that as the belt 4 is stretched, its thickness decreases, making it more prone to vibration during high-speed operation. Therefore, this invention uses a fixed platform 604 to drive the inner fixed roller 605 and the outer fixed roller 606 to rotate. As the inner fixed roller 605 and the outer fixed roller 606 rotate, the contact area between the inner fixed roller 605 and the outer fixed roller 606 and the belt 4 increases, thereby improving the ability of the inner fixed roller 605 and the outer fixed roller 606 to suppress the belt 4 and prevent the belt 4 from vibrating at high speed due to the reduced thickness of the belt 4.
[0037] See Figures 9-11 The cooling and cleaning assembly 9 includes a sleeve 901 rotatably mounted on the inner fixed roller 605 and the outer fixed roller 606. A plurality of cooling pipes 904 are installed between the sleeves 901. Cooling ports 902 are provided at the top and bottom of the sleeves 901. The cooling ports 902 are connected to the cooling pipes 904 and are also connected to the liquid inlet and outlet of the inner fixed roller 605.
[0038] Specifically, a baffle 903 is installed on the cooling pipe 904, which divides the gaps between the cooling pipes 904 into several adsorption chambers 906. A fiber board 905 is installed on the side of the baffle 903 near the inner fixed roller 605, and a fiber sleeve 908 is installed on the inner fixed roller 605. The friction between the fiber board 905 and the fiber sleeve 908 generates electrostatic adsorption to attract the yarn on the belt 4. A bearing 907 is installed on the outer wall of the sleeve 901, and the belt 4 is attached to the bearing 907.
[0039] It should be noted that when the duct belt 4 is running, the side wall of the duct belt 4 is in contact with the bearing 907. When the duct belt 4 passes through the inner fixed roller 605 and the outer fixed roller 606, the duct belt 4 drives the bearing 907 to rotate. Due to the friction between the fiberboard 905 and the fiber sleeve 908, the sleeve 901 is fixed.
[0040] When the conveyor belt 4 absorbs thread ends and debris, its thickness increases. As the conveyor belt 4 passes the sleeve 901, it comes into contact with the sleeve, causing the sleeve 901 to rotate. During this rotation, the fiberboard 905 and fiber sleeve 908 rub against each other, generating static electricity. Under this static electricity, the thread ends on the conveyor belt 4 are drawn into the absorption chamber 906, preventing localized slippage or tension fluctuations in the conveyor belt 4. After being drawn into the absorption chamber 906, the thread ends adhere to the outer fixed roller 606, preventing the cold air from the cooling pipe 904 from diffusing towards the inner fixed roller 605, thus improving the heat dissipation effect of the cooling pipe 904 on the conveyor belt 4.
[0041] It should be noted that all electrical appliances in this invention are designed with a grounding device to prevent static electricity from damaging the electrical components.
[0042] See Figures 1-2 The twisting component 2 also includes a liner tensioner 202 and a yarn feeder 201. The fixing tube of the liner tensioner 202 is located in the central inner hole of the yarn feeder 201 and is connected and cooperated with the twisting disc 203. The outer shell of the twisting component 2 is made of aluminum-magnesium alloy.
[0043] It should be noted that the outer shell of the twisting component 2 of the present invention is made of aluminum-magnesium alloy material, and the twisting component 2 is designed to reduce weight and power consumption, thereby achieving the effect of energy saving.
[0044] The implementation principle of this invention is as follows: Motor 502 drives drive wheel 501 to rotate, and drive wheel 501 drives spindle body 205 to rotate through belt 4, causing spindle body 205 to rotate at high speed to achieve twisting operation.
[0045] The present invention delivers coolant through the top inlets of the inner fixed roller 605 and the outer fixed roller 606. The coolant enters the cooling pipe 904 through the cooling port 902 to dissipate heat on both sides of the belt 4 between the outer fixed roller 606 and the inner fixed roller 605. Finally, the coolant is discharged through the bottom outlets of the inner fixed roller 605 and the outer fixed roller 606.
[0046] When it is necessary to tighten the belt 4, the second motor 801 drives the lead screw 802 to rotate. The lead screw 802 is connected to the guide block 803 through a transmission connection. The guide block 803 moves closer to the second motor 801. At this time, the guide block 803 drives the roller sleeve 806 and the tension wheel 7 to move closer to each other along the slide groove 807 through the connecting rod 805. The tension wheel 7 is used to adjust the tightness of the belt 4. During this process, the inner fixed roller 605 and the outer fixed roller 606 clamp the belt 4 in the middle, fixing the contact area between the belt 4 and the spindle body 205, that is, fixing the wrap angle, limiting the lateral displacement of the belt 4, and preventing the belt 4 from vibrating under the action of high-speed centrifugal force. Moreover, the present invention further suppresses the high-speed vibration of the belt 4 by clamping the belt 4 with the inner fixed roller 605 and the outer fixed roller 606.
[0047] It should be noted that when preload is applied to the duct belt 4 via the tensioning pulley 7, the tension of the duct belt 4 increases, causing it to be stretched along its length, resulting in a corresponding decrease in its thickness to maintain a substantially constant volume. See also Figure 12 As shown, the tensioning wheel 7 applies a pre-tension force to the belt 4, and the belt 4 is in close contact with the inner fixed roller 605. Due to the reduced thickness of the belt 4, a gap is generated between the belt 4 and the outer fixed roller 606. The cooling and cleaning components 9 on the outer fixed roller 606 reduce the heat dissipation capacity of the belt 4, resulting in a temperature difference between the front and back of the belt 4. The temperature difference will accelerate material fatigue and life loss.
[0048] Based on this, when the second motor 801 drives the guide block 803 to move closer to the second motor 801, the L-shaped rack 804 on the guide block 803 drives the gear disk 602 to rotate. See [link / reference] Figures 6-7 The toothed disc 602 drives the fixed platform 604 to rotate synchronously. When the fixed platform 604 rotates, the top block 607 presses the outer fixed roller 606 by cooperating with the inner convex ring 603, so that the outer fixed roller 606 is in contact with the back of the duct belt 4. At this time, the inner fixed roller 605 and the outer fixed roller 606 clamp the duct belt 4 again, which promotes uniform heat dissipation on the front and back of the duct belt 4 and avoids the temperature difference between the front and back of the duct belt 4, which would cause the material of the duct belt 4 to fatigue faster.
[0049] It should be noted that as the belt 4 is stretched, its thickness decreases, making it more prone to vibration during high-speed operation. Therefore, this invention uses a fixed platform 604 to drive the inner fixed roller 605 and the outer fixed roller 606 to rotate. As the inner fixed roller 605 and the outer fixed roller 606 rotate, the contact area between the inner fixed roller 605 and the outer fixed roller 606 and the belt 4 increases, thereby improving the ability of the inner fixed roller 605 and the outer fixed roller 606 to suppress the belt 4 and prevent the belt 4 from vibrating at high speed due to the reduced thickness of the belt 4.
[0050] It should be noted that when the duct belt 4 absorbs thread ends and debris, the thickness of the duct belt 4 increases. When the duct belt 4 passes through the sleeve 901, the duct belt 4 comes into contact with the sleeve 901, causing the duct belt 4 to drive the sleeve 901 to rotate. When the sleeve 901 rotates, the fiberboard 905 and the fiber sleeve 908 rub against each other to generate static electricity. Under the action of static electricity, the thread ends on the duct belt 4 are sucked into the adsorption cavity 906, thus avoiding local slippage or tension fluctuation of the duct belt 4.
