Description

Technical Field

[0001] This invention relates to the field of tower taper detection technology, specifically to a structure and method for real-time determination of the radius of the cone portion of a tower core mold and for winding molding. Background Technology

[0002] Feed towers made of fiberglass tubes have advantages such as smooth interior, low flow resistance, and lightweight structure. These feed towers can be used in animal husbandry for storing feed, such as... Figure 1 As mentioned above, when manufacturing the bulge made of glass fiber tube, glass fiber needs to be wound on the core mold 1, which has the same shape as the bulge. Unlike the cylindrical part of the core mold 1, a wide glass fiber can be wound at once (multiple sets of glass fibers come together to form the width).

[0003] For the cone 101, because the cone 101 is difficult to align with the winding direction, when the glass fiber wound in a single operation is too wide, it is difficult to ensure that the cone and the glass fiber fit together, resulting in winding difficulties. For a long time, manual winding has been required, but because the radius of the material tower is too large, there is a problem of low efficiency.

[0004] In the existing technology, glass fibers are wound by rotating the mandrel. If the number of glass fibers wound at one time is reduced to reduce the winding width, the tensile strength of the glass fibers during the winding process will be reduced. Especially during the winding process of the cone, the winding linear speed is a variable process. If the winding width of the glass fibers is further reduced, it will easily lead to the breakage of the glass fibers.

[0005] Therefore, in response to the above problems, a structure and method for real-time determination of the cone radius of the core mold of the material tower and a winding molding system and method are proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a structure and method for real-time determination of the radius of the cone portion of the core mold of a material tower and for winding molding. The rotation of the feeding wheel does not use coupling or rigid transmission. The rotational damping of the feeding wheel gradually decreases as the rotational speed increases. By making the driving load linear speed of the glass fiber feeding wheel slightly lower than the real-time winding linear speed of the cone portion, the pulling force on the feeding wheel when the core mold rotates can be reduced, and the tension can be maintained through the difference in driving speed, thus preventing the wound glass fiber thread from becoming loose and disordered.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a structure for real-time determination of the cone radius of the core mold of the material tower, including a base, a rotating shaft rotatably connected to the top of the base via a bearing, the outer side of the rotating shaft being detachably connected to the inner side of the core mold via bolts or other means, a motor being fixedly connected to the top of the base, the end of the motor's main shaft being fixedly connected to the rotating shaft, and a drive wheel being fixedly connected to the outer side of the rotating shaft;

[0008] The top of the base is rotatably connected to a sleeve via a bearing. The top of the base is slidably connected to a pull rod via a sliding sleeve. The top of the base is fixedly connected to a telescopic rod. The inner side of the sleeve is screwed with a lead screw, which is fixedly connected to the pull rod and the telescopic rod. The outer side of the sleeve is fixedly connected to a driven wheel, which rotates synchronously with the driving wheel via a transmission belt.

[0009] The pull rod is equipped with a wire feeding wheel. An outer rod is fixedly connected to the top of the pull rod, and an inner rod is slidably connected to the inner side of the outer rod. The inner rod can abut against the surface of the cone. The bottom end of the inner rod is a piston. A second spring is fixedly connected between the piston and the inner side of the outer rod. A potentiometer is fixedly connected to one side of the inner rod. A fixing block is fixedly connected to the inner side of the top of the outer rod. The fixing block slides on the potentiometer. The real-time radius of the cone winding position is obtained by obtaining the position of the fixing block on the potentiometer.

[0010] In this invention, in order to match the wire feeding speed corresponding to the winding position of the cone when the cone is wound, the present invention is provided with a cone radius real-time determination structure. When the motor rotates, the mandrel rotates at a constant speed. Because the driven wheel and the driving wheel achieve synchronous rotation through the transmission belt, the sleeve is supported by the base. When the mandrel rotates, the sleeve rotates synchronously. The lead screw inside the sleeve can move to the right. In order to prevent the lead screw and the sleeve from rotating synchronously, a telescopic rod is fixedly connected to the right side of the lead screw. The fixed section and the sliding section of the telescopic rod are keyed together and are non-rotatable telescopic rods.

[0011] The lead screw can move to the right, driving the pull rod to move to the right, and simultaneously driving the wire feed wheel to move to the right, thus achieving winding movement;

[0012] As a preferred structure for real-time determination of the cone radius of the core mold of the material tower in this invention, the outer rod is bent to one side so that the middle surface of the inner rod and the wire feeding wheel are on the same plane, thereby obtaining the real-time radius of the cone winding position.

[0013] Because the inner rod and the wire feeding wheel are almost on the same plane, that is, the inner rod is near the winding position of the cone. During the movement of the lead screw to the right, the fixed block slides on the potentiometer. By obtaining the position of the fixed block on the potentiometer, the real-time radius of the winding position of the cone can be obtained. After obtaining the real-time radius of the winding position of the cone and the rotation speed of the mandrel, the real-time linear speed of winding can be obtained.

[0014] The conical winding molding system for the core mold of the fiber tower also includes a drive wheel rotatably connected to the outside of a tie rod, a feed wheel slidably mounted on the outside of the drive wheel, a key connection between the drive wheel and the feed wheel, a fan blade fixedly connected to one side of the drive wheel, and a high-pressure air chamber detachably connected to the end of the tie rod. The high-pressure air chamber is connected to an air compressor to maintain internal pressure. The output end of the high-pressure air chamber is a blowpipe, which is equipped with an electric speed control valve to adjust the flow rate. The blowpipe blows the fan blade on one side of the drive wheel, causing the drive wheel to rotate. During the winding process, the maximum surface linear velocity of the feed wheel driven by the blowpipe is slightly less than the linear velocity of the corresponding winding position of the conical section. In order to maintain the consistency of the linear velocity between the feed wheel and the corresponding winding position of the conical section, a tension is applied to the feed wheel during the winding process of the conical section, thereby maintaining the tension of the wound glass fiber.

[0015] In this invention, in order to ensure tightness of the fit, the number of glass fibers wound in a single cone is limited and the load that the glass fibers can withstand is low. This invention chooses to achieve the wire feeding of the wire feeding wheel through the combined action of airflow side blowing and core mold rotation pulling.

[0016] The side airflow is used to provide most of the driving force, in order to prevent the problem of excessive pulling force and easy rope breakage caused by the continuous increase of the linear velocity of the cone when the core mold is independently pulled and rotated in the prior art.

[0017] During the conical winding process, the winding linear velocity continuously increases due to the movement of the conical winding position;

[0018] In the existing technology, it is difficult to keep the speed of the feeding wheel perfectly matched. The existing technology uses contact drive, such as shaft drive, or magnetic coupling or hydraulic coupling, so that the output end and input end can be reversed. When the winding speed of the cone part is greater than the speed of the feeding wheel, the feeding wheel cannot disengage from the transmission or coupling state, and the original driving end will become the output end. At this time, the small number of glass fibers will not be able to bear the load and will break.

[0019] The method of providing driving force by blowing air from the side in this invention can avoid the problem in the prior art where the output and input ends can be reversed by contact transmission or coupling transmission. The blowing air from one side provides a superimposed vector blowing force, which, together with the rotation and pulling of the mandrel, drives the wire feeding wheel, so that the speed of the wire feeding wheel is consistent with the winding speed of the cone.

[0020] The core mold pulling and rotating drive method occupies a small part to ensure tension and prevent the wound glass fiber from loosening. It omits the structure of tension control using tensioning wheels in the existing technology. At the same time, the tension provided by the existing tensioning wheels is too large, which will aggravate the load on the glass fiber and is not suitable for use with a small number of glass fibers.

[0021] In a preferred embodiment of the core mold cone winding forming system of the present invention, the drive wheel and the wire supply wheel are limited by a limiting pin. The limiting pin is installed on the right side of the wire supply wheel and can slide out of the drive wheel. When the pull rod moves to the right, the drive wheel and the wire supply wheel move synchronously. After the high-pressure air chamber is removed, the wire supply wheel can slide to the left and be taken out.

[0022] When the pull rod pulls the drive wheel to move to the right, the drive wheel drives the wire supply wheel to move synchronously through the limit pin. The wire supply wheel can be replaced after the high-pressure air chamber is removed. The connection between the high-pressure air chamber and the pull rod can be a threaded connection.

[0023] In a preferred embodiment of the winding forming system for the core mold cone of the material tower of the present invention, a groove is provided on the inner side of the drive wheel, and a top block is slidably connected in the groove. A first spring is fixedly connected between the top block and the inner side of the groove to provide damping and prevent the wire feeding wheel from producing excess wire under environmental interference or inertia when it is stationary or at low speed. As the wire feeding wheel accelerates, the damping decreases under the action of centrifugal force to prevent wire breakage. Since the winding speed is a gradual process, there is no need to worry about the wound glass fiber wire becoming loose.

[0024] The method for winding and forming the cone part of the core mold of the material tower includes the following steps:

[0025] Step 1: Open the high-pressure air chamber and conduct a blow-rotation test on the wire feed wheel separately in advance. Continuously increase the opening of the electric speed control valve and increase the flow rate of the blow pipe to obtain the relationship between the opening of the electric speed control valve and the linear velocity v1 of the wire feed wheel surface. The rotation speed of the wire feed wheel during rotation can also be obtained by a laser tachometer. Install the laser tachometer on the pull rod and face it toward the drive wheel.

[0026] Step 2: The glass fiber on the cone is wound from left to right. The glass fiber on the feed wheel is attached to the cone. The motor rotates at a constant speed. The feed wheel moves to one side continuously as the motor rotates. The winding radius of the winding position of the cone is obtained by the extension and retraction of the inner rod within the outer rod, and then the linear velocity v2 of the winding position is obtained.

[0027] Step 3: Adjust the opening of the electric speed control valve so that the surface linear velocity v1 of the feed wheel is slightly less than the linear velocity v2 at the winding position;

[0028] Step 4: As the radius of the cone winding position gradually increases, the rotation speed of the wire feeding wheel increases accordingly, the pulling force of the cone on the wire feeding wheel increases accordingly, and the top block gradually resists the elastic force of the first spring under the action of centrifugal force, reducing the damping of the top block on the pull rod to prevent wire breakage.

[0029] In this invention, the difference in the decrease in the diameter of the feed wheel as the glass fiber is released can be reduced by increasing the width of the feed wheel and reducing the thickness of the glass fiber wound on the feed wheel. In this invention, such diameter difference caused by the fiber is negligible.

[0030] As a preferred embodiment of the core mold cone winding forming system of the present invention, the tie rod is provided with an expansion part at the drive wheel, and a groove is also provided in the expansion part. An oil chamber is provided in the center of the expansion part. A pressure block and a stop block are slidably connected in the groove. The pressure block abuts against the inner side of the drive wheel. A third spring is fixedly connected between the pressure block and the stop block. The stop block faces the oil chamber. The damping force in the change of the speed of the wire feeding wheel is adjusted by the increase or decrease of the hydraulic oil in the oil chamber, so as to ensure tension and prevent wire breakage.

[0031] In a preferred embodiment of the core mold cone winding forming system of the present invention, an oil cavity is located between the inner side of the outer rod and the outer side of the inner rod. The oil cavity and the oil chamber are connected by an oil pipe. When the inner rod descends, the piston descends, the oil cavity draws hydraulic oil from the oil chamber, and the damping force of the pressure block on the drive wheel decreases.

[0032] Unlike the above solutions, this invention also provides a damping control method for the drive wheel. This damping control method is more linear. As the speed of the wire feed wheel increases, the damping force also decreases linearly. As the inner rod moves to the right, the inner rod descends, the piston descends, the oil chamber draws hydraulic oil from the oil chamber, the pressure block moves towards the oil chamber, the third spring extends, the elastic force decreases, and the damping force on the drive wheel decreases. The extension and contraction of the third spring satisfies Hooke's Law.

[0033] In a preferred embodiment of the winding forming system for the cone part of the core mold of the present invention, a groove is provided on the inner side of the drive wheel, and the key slides in the groove. A tension sensor is fixedly connected to one side of the groove. Under the above configuration, more precise control of the drive wheel speed can be achieved, and the tension of the glass fiber can be controlled within the tension range of the tension spring. A tension spring is fixedly connected between the tension sensor and the key. In the initial state, the key is in the middle position of the groove, and the tension sensor reading is zero. During the winding process, when the tension sensor reading increases, that is, the speed of the surface wire feeding wheel needs to be increased, the opening of the electric speed regulating valve needs to be increased. When the tension sensor reading decreases, the opening of the electric speed regulating valve is reduced accordingly.

[0034] The method for winding and forming the cone part of the core mold of the material tower includes the following steps:

[0035] Step 1: The glass fiber on the cone is wound from left to right, and the glass fiber on the feed wheel is attached to the mandrel. The motor rotates at a constant speed. The motor is a geared motor, and the feed wheel moves to one side continuously as the motor rotates.

[0036] Step 2: During the winding process, when the tension sensor reading increases, increase the opening of the electric speed control valve;

[0037] Step 3: As the radius of the cone winding position gradually increases, the speed of the feed wheel increases accordingly, the pulling force of the cone on the feed wheel increases accordingly, the inner rod is pushed down by the cone, the piston drops, the oil chamber draws hydraulic oil from the oil chamber, and the damping force of the pressure block on the drive wheel decreases to prevent wire breakage.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] 1. The material tower core mold cone radius is determined in real time. During the winding of the cone, to match the wire feeding speed corresponding to the winding position, this invention features a structure for real-time cone radius determination. When the motor rotates, the core mold rotates at a constant speed because the driven wheel and the driving wheel rotate synchronously via a transmission belt. The sleeve is supported by the base. When the core mold rotates, the sleeve rotates synchronously, and the lead screw inside the sleeve can move to the right. Because the inner rod and the wire feeding wheel are approximately on the same plane, i.e., the inner rod is near the winding position of the cone, the fixing block slides on the potentiometer during the rightward movement of the lead screw. By obtaining the position of the fixing block on the potentiometer, the real-time radius of the cone winding position is obtained. After obtaining the real-time radius of the cone winding position and the core mold rotation speed, the real-time winding speed can be obtained.

[0040] 2. In this material tower core mold conical winding forming system, in order to ensure tightness of the fit, the number of glass fibers wound in a single winding of the conical part is limited, and the load that the glass fibers can withstand is low. This invention selects to achieve the wire feeding wheel release through the combined action of airflow side blowing and core mold rotation pulling. Airflow side blowing is used to provide most of the driving force to prevent the problem of excessive pulling force caused by the continuous increase of the conical linear speed when the core mold is pulled and rotated independently in the prior art, which is easy to break the rope. During the conical winding process, because the winding position of the conical part moves, its winding linear speed is constantly increasing. In the prior art, it is difficult to keep the speed of the wire feeding wheel perfectly matched. In the prior art, contact drive, such as shaft drive, or magnetic coupling, or hydraulic coupling, is used to make the output end and input end inverted. When the winding linear speed of the conical part is greater than the speed of the wire feeding wheel, the wire feeding wheel cannot disengage from the transmission or coupling state, and the original driving end will become the output end. At this time, the small number of glass fibers will not be able to bear the load and will break.

[0041] 3. The core mold cone winding forming system of this material tower avoids the problem of the output and input ends being reversed in the prior art by providing driving force through airflow side rotation by using contact transmission or coupling transmission. The airflow side rotation provides a superimposed vector rotation force, which drives the wire feeding wheel together with the rotation and pulling of the core mold, so that the speed of the wire feeding wheel is consistent with the winding line speed of the cone.

[0042] 4. In this core mold cone winding molding system for the material tower, a small portion of the core mold is driven by pulling and rotating to ensure tension and prevent the wound glass fiber from loosening. This eliminates the structure of tension control using tension rollers in the existing technology. At the same time, the tension provided by the existing tension rollers is too large, which will aggravate the load on the glass fiber and is not suitable for use with a small amount of glass fiber.

[0043] 5. The core mold cone winding forming system of this material tower has a groove on the inner side of the drive wheel, and a top block is slidably connected in the groove. A first spring is fixedly connected between the top block and the inner side of the groove to provide damping and prevent the wire feeding wheel from producing excess wire due to environmental interference or inertia when it is stationary or at low speed. As the wire feeding wheel accelerates, the damping decreases under the action of centrifugal force to prevent wire breakage. Because the winding speed is a gradual process, there is no need to worry about the wound glass fiber wire becoming loose.

[0044] 6. In the core mold cone winding forming system of the material tower, the present invention also provides a damping control method for the drive wheel. This damping control method is more linear. As the speed of the wire feeding wheel increases, the damping force also decreases linearly. As the inner rod moves to the right, the inner rod descends, the piston descends, the oil chamber draws hydraulic oil from the oil chamber, the pressure block moves towards the oil chamber, the third spring stretches, the elastic force decreases, and the damping force on the drive wheel decreases.

[0045] 7. In this solution, the core mold cone winding forming system of the material tower can achieve more precise control of the drive wheel speed, and control the tension of the glass fiber within the tension range of the tension spring. A tension spring is fixedly connected between the tension sensor and the key. In the initial state, the key is in the middle position of the slide groove and the tension sensor reading is zero. During the winding process, when the tension sensor reading increases, that is, the speed of the surface wire feeding wheel needs to be increased, and the opening of the electric speed regulating valve needs to be increased.

[0058] 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.

[0059] Example 1, please refer to Figures 1-5 The present invention provides a technical solution:

[0060] The structure for determining the radius of the cone part of the core mold in real time includes a base 2. The top of the base 2 is rotatably connected to a rotating shaft 3 via a bearing. The outer side of the rotating shaft 3 is detachably connected to the inner side of the core mold 1 via bolts or other means. A motor 6 is fixedly connected to the top of the base 2. The end of the main shaft of the motor 6 is fixedly connected to the rotating shaft 3. A drive wheel 5 is fixedly connected to the outer side of the rotating shaft 3.

[0061] The top of the base 2 is also rotatably connected to the sleeve 18 via a bearing. The top of the base 2 is slidably connected to the pull rod 11 via a sliding sleeve. The top of the base 2 is fixedly connected to the telescopic rod 9. The inner side of the sleeve 18 is screwed with the lead screw 10. The lead screw 10 is fixedly connected to the pull rod 11. The lead screw 10 is fixedly connected to the telescopic rod 9. The outer side of the sleeve 18 is fixedly connected to the driven wheel 7. The driven wheel 7 and the driving wheel 5 rotate synchronously via a transmission belt 8.

[0062] A wire feeding wheel 13 is provided on the pull rod 11. An outer rod 14 is fixedly connected to the top of the pull rod 11. An inner rod 141 is slidably connected to the inner side of the outer rod 14. The inner rod 141 can abut against the surface of the cone 101. The bottom end of the inner rod 141 is a piston. A second spring 143 is fixedly connected between the piston and the inner side of the outer rod 14. A potentiometer 142 is fixedly connected to one side of the inner rod 141. A fixing block 144 is fixedly connected to the inner side of the top of the outer rod 14. The fixing block 144 slides on the potentiometer 142. The real-time radius of the winding position of the cone 101 is obtained by obtaining the position of the fixing block 144 on the potentiometer 142.

[0063] In this invention, in order to match the wire feeding speed corresponding to the winding position of the cone 101 when winding the cone 101, the present invention is provided with a cone radius real-time determination structure. When the motor 6 rotates, the mandrel 1 rotates at a constant speed. Because the driven wheel 7 and the driving wheel 5 achieve synchronous rotation through the transmission belt 8, the sleeve 18 is supported by the base. When the mandrel 1 rotates, the sleeve 18 rotates synchronously. The lead screw 10 inside the sleeve 18 can move to the right. In order to prevent the lead screw 10 and the sleeve 18 from rotating synchronously, a telescopic rod 9 is fixedly connected to the right side of the lead screw 10. The fixed section and the sliding section of the telescopic rod 9 are keyed together and are non-rotatable telescopic rods.

[0064] The lead screw 10 can move to the right, driving the pull rod 11 to move to the right, and simultaneously driving the wire feed wheel 13 to move to the right, thus realizing the winding movement;

[0065] Specifically, the outer rod 14 bends to one side, so that the inner rod 141 and the middle surface of the wire feed wheel 13 are on the same plane, thereby obtaining the real-time radius of the winding position of the cone 101.

[0066] Because the inner rod 141 and the wire feeding wheel 13 are roughly on the same plane, that is, the inner rod 141 is near the winding position of the cone 101. During the movement of the lead screw 10 to the right, the fixing block 144 slides on the potentiometer 142. By obtaining the position of the fixing block 144 on the potentiometer 142, the real-time radius of the winding position of the cone 101 can be obtained. After obtaining the real-time radius of the winding position of the cone 101 and the rotation speed of the mandrel 1, the real-time linear speed of winding can be obtained.

[0067] The core mold cone winding forming system for the fiber optic tower also includes a drive wheel 12 rotatably connected to the outside of a tie rod 11, a wire feed wheel 13 slidably mounted on the outside of the drive wheel 12, a key 131 connecting the drive wheel 12 and the wire feed wheel 13, a fan blade 121 fixedly connected to one side of the drive wheel 12, a high-pressure air chamber 4 detachably connected to the end of the tie rod 11, the high-pressure air chamber 4 being connected to an air compressor to maintain internal pressure, the output end of the high-pressure air chamber 4 being a blowpipe 41, an electric speed regulating valve 411 for adjusting flow rate being installed on the blowpipe 41, the blowpipe 41 blowing towards the fan blade 121 on one side of the drive wheel 12 to rotate the drive wheel 12, during the winding process, the maximum surface linear velocity of the wire feed wheel 13 driven by the blowpipe 41 is slightly less than the linear velocity of the corresponding winding position of the cone 101, in order to maintain the consistency of the linear velocity of the wire feed wheel 13 and the corresponding winding position of the cone 101, the cone 101 applies a tension to the wire feed wheel 13 during the winding process, thereby maintaining tension on the wound glass fiber.

[0068] In this invention, in order to ensure tightness of the fit, the number of glass fibers wound by the cone 101 at one time is limited, and the load that the glass fibers can withstand is low. This invention chooses to achieve the feeding of the wire wheel 13 by the combined action of airflow side blowing and the rotation and pulling of the core mold 1.

[0069] The side airflow is used to provide most of the driving force, in order to prevent the problem of excessive pulling force caused by the continuous increase of the linear velocity of the cone 101 when the core mold 1 is independently pulled and rotated in the prior art, which is easy to break the rope.

[0070] During the winding process of the cone 101, the winding linear speed of the cone 101 keeps increasing due to the movement of the winding position;

[0071] In the prior art, it is difficult to keep the speed of the feeding wheel 13 perfectly matched. In the prior art, the output end and input end can be reversed by contact drive, such as shaft drive, or magnetic coupling or hydraulic coupling. When the winding speed of the cone 101 is greater than the speed of the feeding wheel 13, the feeding wheel 13 cannot disengage from the transmission or coupling state, and the original driving end will become the output end. At this time, the small number of glass fibers will not be able to bear the load and will break.

[0072] In this invention, the method of providing driving force by blowing air from the side can avoid the problem in the prior art where the output and input ends can be reversed by contact transmission or coupling transmission. The blowing air from one side provides a superimposed vector blowing force, which, together with the rotation and pulling of the core mold 1, drives the wire feeding wheel 13, so that the speed of the wire feeding wheel 13 is consistent with the winding speed of the cone 101.

[0073] The pull-rotation drive of the core mold 1 occupies a small portion to ensure tension and prevent the wound glass fiber from loosening. It omits the structure of tension control using tensioning wheels in the existing technology. At the same time, the tension provided by the existing tensioning wheels is too large, which will aggravate the load on the glass fiber and is not suitable for use with a small number of glass fibers.

[0074] Specifically, the drive wheel 12 and the wire supply wheel 13 are limited by a limit pin 16. The limit pin 16 is installed on the right side of the wire supply wheel 13. The limit pin 16 can slide out of the drive wheel 12. When the pull rod 11 moves to the right, the drive wheel 12 and the wire supply wheel 13 move synchronously. After the high-pressure air chamber 4 is removed, the wire supply wheel 13 can slide to the left and be removed.

[0075] When the pull rod 11 pulls the drive wheel 12 to the right, the drive wheel 12 drives the wire supply wheel 13 to move synchronously through the limit pin 16. The wire supply wheel 13 can be replaced after the high-pressure air chamber 4 is removed. The connection between the high-pressure air chamber 4 and the pull rod 11 can be a threaded connection.

[0076] Specifically, a groove is provided on the inner side of the drive wheel 12, and a top block 122 is slidably connected in the groove. A first spring 123 is fixedly connected between the top block 122 and the inner side of the groove to provide damping and prevent the wire feeding wheel 13 from producing excess wire due to environmental interference or inertia when it is stationary or at low speed. As the wire feeding wheel 13 accelerates, the damping decreases under the action of centrifugal force to prevent wire breakage. Since the winding speed is a gradual process, there is no need to worry about the wound glass fiber wire becoming loose.

[0077] The method for winding and forming the cone part of the core mold of the material tower includes the following steps:

[0078] Step 1: Open the high-pressure air chamber 4 and conduct a blow-rotation test on the wire feed wheel 13 separately in advance. Continuously increase the opening of the electric speed regulating valve 411 and increase the flow rate of the blow pipe 41 to obtain the relationship between the opening of the electric speed regulating valve 411 and the surface linear velocity v1 of the wire feed wheel 13. The rotation speed of the wire feed wheel 13 during rotation can also be obtained by a laser tachometer. Install the laser tachometer on the pull rod 11 and face it toward the drive wheel 12.

[0079] Step 2: The glass fiber on the cone 101 is wound from left to right. The glass fiber on the feed wheel 13 is attached to the cone 101. The motor 6 rotates at a constant speed. The feed wheel 13 moves to one side continuously as the motor 6 rotates. The winding radius of the winding position of the cone 101 is obtained by the extension and retraction of the inner rod 141 within the outer rod 14, and then the linear velocity v2 of the winding position is obtained.

[0080] Step 3: Adjust the opening of the electric speed control valve 411 so that the surface linear velocity v1 of the wire feed wheel 13 is slightly less than the linear velocity v2 at the winding position;

[0081] Step 4: As the radius of the winding position of the cone 101 gradually increases, the rotation speed of the wire feeding wheel 13 increases accordingly, the pulling force of the cone 101 on the wire feeding wheel 13 increases accordingly, and the top block 122 gradually resists the elastic force of the first spring 123 under the action of centrifugal force, and the damping of the top block 122 on the pull rod 11 decreases to prevent wire breakage.

[0082] In this invention, the difference in the diameter of the wire feeding wheel 13 as the glass fiber is released can be reduced by increasing the width of the wire feeding wheel 13 and reducing the thickness of the glass fiber wound on the wire feeding wheel 13. In this invention, such diameter difference caused by the wire feeding wheel is negligible.

[0083] Example 2 is an alternative to the previous example; the same parts will not be repeated. Please refer to [link / reference]. Figures 1-4 , Figures 6-11 ;

[0084] The pull rod 11 is provided with an expansion part 15 at the drive wheel 12. The expansion part 15 is also provided with a groove. An oil chamber 154 is provided in the center of the expansion part 15. A pressure block 151 and a stop block 152 are slidably connected in the groove. The pressure block 151 abuts against the inside of the drive wheel 12. A third spring 153 is fixedly connected between the pressure block 151 and the stop block 152. The stop block 152 faces the oil chamber 154. The damping force in the speed change of the wire feeding wheel 13 is adjusted by the increase or decrease of the hydraulic oil in the oil chamber 154, so as to ensure tension and prevent wire breakage.

[0085] Specifically, there is an oil chamber 145 between the inner side of the outer rod 14 and the outer side of the inner rod 141. The oil chamber 145 is connected to the oil chamber 154 through an oil pipe 17. When the inner rod 141 descends, the piston descends, the oil chamber 145 draws hydraulic oil from the oil chamber 154, and the damping force of the pressure block 151 on the drive wheel 12 decreases.

[0086] Unlike the above solutions, the present invention also provides a damping control method for the drive wheel 12. This damping control method is more linear. As the rotational speed of the wire feed wheel 13 increases, the damping force also decreases linearly. As the inner rod 141 moves to the right, the inner rod 141 descends, the piston descends, the oil chamber 145 draws hydraulic oil from the oil chamber 154, the pressure block 151 moves towards the oil chamber 145, the third spring 153 extends, the elastic force decreases, and the damping force on the drive wheel 12 decreases. The extension and retraction of the third spring 153 satisfies Hooke's law.

[0087] Specifically, a groove is provided on the inner side of the drive wheel 12, and the key 131 slides in the groove. A tension sensor 133 is fixedly connected to one side of the groove. With the above configuration, this solution can achieve more precise control of the speed of the drive wheel 12, and control the tension of the glass fiber within the tension range of the tension spring 132. The tension sensor 133 and the key 131 are fixedly connected by the tension spring 132. In the initial state, the key 131 is in the middle position of the groove, and the reading of the tension sensor 133 is zero. During the winding process, when the reading of the tension sensor 133 increases, that is, the speed of the surface wire feeding wheel 13 needs to be increased, and the opening of the electric speed regulating valve 411 needs to be increased. When the tension sensor 133 decreases, the opening of the electric speed regulating valve 411 is reduced accordingly.

[0088] This embodiment also discloses a method for winding and forming the cone part of a material tower core mold, the steps of which include:

[0089] Step 1: The glass fiber on the cone 101 is wound from left to right, and the glass fiber on the feed wheel 13 is attached to the core mold 1. The motor 6 rotates at a constant speed. The motor 6 is a geared motor. The feed wheel 13 moves to one side continuously as the motor 6 rotates.

[0090] Step 2: During the winding process, when the reading of the tension sensor 133 increases, the opening of the electric speed control valve 411 is increased;

[0091] Step 3: As the radius of the winding position of the cone 101 gradually increases, the rotation speed of the wire feeding wheel 13 increases accordingly, the pulling force of the cone 101 on the wire feeding wheel 13 increases accordingly, the inner rod 141 is pushed down by the cone 101, the piston drops, the oil chamber 145 draws hydraulic oil from the oil chamber 154, and the damping force of the pressure block 151 on the drive wheel 12 decreases to prevent wire breakage.

[0092] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
