Description

Technical Field

[0001] This invention relates to the field of enameled copper flat wire winding machines, and more specifically, to an emergency stop protection device for enameled copper flat wire winding machines. Background Technology

[0002] In the production and processing of enameled copper flat wire, a winding reel on a winding machine is needed to wind the enameled copper flat wire. In order to avoid malfunctions during the operation of the winding machine, the winding reel needs to be stopped urgently. At this time, an emergency stop protection device for enameled copper flat wire winding machine is required.

[0003] Existing patent CN215885861U discloses an emergency stop protection device for an enameled copper flat wire winding machine, comprising a base plate, a support rod fixedly mounted on the upper surface of the base plate, a winding reel body rotatably connected to the inner side of the support rod, and a connecting disc fixedly mounted on the right end of the winding reel body; a motor, bolted to the upper surface of the base plate and located to the right of the support rod, a connecting shell fixedly mounted on the upper surface of the base plate and located to the left of the motor, and a toothed belt externally connected to the output end of the motor; and a receiving rod rotatably connected to the upper interior of the connecting shell, with an adjusting disc fixedly mounted on the outer side of the middle of the receiving rod. This emergency stop protection device for an enameled copper flat wire winding machine allows for an emergency stop of the winding reel during the winding process of the enameled copper flat wire, facilitating the provision of buffer space for the winding reel, reducing the risk of damage to the enameled copper flat wire, avoiding impact on the quality of the enameled copper flat wire, and providing good stability during the emergency stop.

[0004] Existing technology can provide an emergency stop for the winding reel of an enameled copper flat wire winding machine, but it still has certain limitations. When braking the winding reel with a set of braking devices that gradually change the braking force, there is a certain buffering effect, but it lacks an emergency stop effect. When the inertia is large, the braking effect is easily limited, causing the winding reel to continue rotating and damaging the enameled copper flat wire.

[0005] How to invent an emergency stop protection device for an enameled copper flat wire winding machine to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] To overcome the above deficiencies, the present invention provides an emergency stop protection device for an enameled copper flat wire winding machine, which aims to improve the problem of the winding reel of the enameled copper flat wire winding machine having a certain buffering effect while braking in an emergency.

[0007] This invention is implemented as follows:

[0008] This invention provides an emergency stop protection device for an enameled copper flat wire winding machine, including a winding roller, a winding motor, and an emergency stop protection mechanism. A set of drive rollers that pass through the winding roller are fixedly installed at the center of the winding roller.

The winding motor is fixedly connected to the ground through a set of fixed seats, and the output shaft of the winding motor is fixedly connected to the drive roller.

[0009] The emergency stop protection mechanism includes a fixed base, which is fixedly connected to the ground. A drive motor is fixedly installed on the top of the fixed base. A threaded drive roller is fixedly installed at the output end of the drive motor. The end of the threaded drive roller away from the drive motor is connected to the fixed base through a set of support frames and bearings and remains rotatable. A brake wheel is fixedly installed at the end of the drive roller that extends to the outside of the take-up roller. Two sets of movable sliders are symmetrically arranged on the outer side wall of the threaded drive roller relative to the brake wheel. Two sets of fixed brake blocks close to the brake wheel are fixedly installed on the side wall of the movable sliders.

[0010] Through the above scheme, during the movement of the fixed brake block toward the brake wheel, the first brake block abuts against the inner brake ring, and the friction gradually increases. As the fixed brake block continues to move, it can push the second brake block against the side wall of the inner brake ring, thereby achieving secondary braking of the brake wheel. By setting two sets of braking forces, the braking force can be suddenly increased. While leaving a certain buffer, it can also perform emergency braking on the take-up roller. Not only does it provide a certain buffer space to avoid damage to the enameled copper flat wire, thus avoiding affecting the quality of the enameled copper flat wire, but it can also achieve emergency stopping of the device to avoid damage to the enameled copper flat wire.

[0011] Preferably, an airtight cavity is provided on the side of the two sets of movable sliders that are close to each other. A rectangular drive slip ring is fitted inside the airtight cavity to limit the movement. The part of the rectangular drive slip ring that contacts the inner wall of the airtight cavity is kept in a sealed state. A return spring is fixedly installed between the rectangular drive slip ring and the inside of the airtight cavity. A set of air passage connecting pipes connected to the inside of the fixed brake block is also fixedly installed on the side wall of the movable slider. One end of the air passage connecting pipe is connected to the end of the airtight cavity away from the rectangular drive slip ring, and the connection is kept in a sealed state.

[0012] An air jet pipe is fixedly installed on the side wall of the fixed brake block, and a section of the air jet pipe extending into the fixed brake block is connected to one end of the air passage connecting pipe extending into the fixed brake block, and the contact point is kept sealed.

[0013] The outlet of the jet pipe is equipped with a one-way valve, and the flow direction of the one-way valve is from the inside of the jet pipe to the outside of the jet pipe. The side wall of the movable slider is also equipped with a one-way valve that communicates with the airtight cavity, and the flow direction of the one-way valve is from the outside of the movable slider to the airtight cavity.

[0014] Preferably, the outer wall of the threaded drive roller is provided with threads at the contact portion with the movable slider, the movable slider and the threaded drive roller are connected by threads, and the thread pitch on both sides is the same, while the thread direction is opposite.

[0015] Preferably, a limiting groove is provided on the top of the fixed base, and a limiting fixing block that matches the limiting groove is fixedly installed at the bottom of the movable slider.

[0016] Preferably, a first sealing oil passage pipe is fixedly installed inside the fixed brake block, a first piston push rod is movably sleeved inside the first sealing oil passage pipe, a piston is provided at one end of the first piston push rod located inside the first sealing oil passage pipe, and a tension spring is fixedly installed between the piston and the top of the inner side of the first sealing oil passage pipe, and a movable ball is provided on the side of the first piston push rod close to the brake wheel.

[0017] The fixed brake block is also provided with a second sealing oil passage pipe. A second piston push rod is movably connected inside the second sealing oil passage pipe. A piston is provided at one end of the second piston push rod located inside the second sealing oil passage pipe. A limit block is fixedly installed at one end of the second piston push rod located outside the second sealing oil passage pipe. A second brake block is fixedly installed at one end of the limit block extending to the outside of the second sealing oil passage pipe.

[0018] A limiting sleeve is fixedly installed on the side of the fixed brake block close to the brake wheel. The first brake block is movably sleeved on the inner side of the limiting sleeve. Multiple sets of compression springs are fixedly installed between the first brake block and the fixed brake block.

[0019] Preferably, the side wall of the brake wheel is provided with a brake inner ring, and the second brake block and the first brake block are constructed of rubber material.

[0020] Preferably, the first sealing oil circuit is connected to the second sealing oil circuit through a set of pipes, and the interior of the first sealing oil circuit and the second sealing oil circuit is filled with hydraulic oil between the pistons of the first piston push rod and the second piston push rod.

[0021] Preferably, the jet pipe has a curved structure, and the top outlet of the jet pipe faces the top of the first braking block.

[0022] Preferably, the length of the first brake block is greater than the length of the jet pipe extending to the outside of the fixed brake block, and the length of the second brake block is less than the length of the first brake block.

[0023] Preferably, the winding motor is electrically connected to the drive motor and the external control center.

[0024] The beneficial effects of this invention are: 01. During the process of the fixed brake block moving towards the brake wheel, the first brake block and the brake inner...

[0025] As the brake ring tightens, friction gradually increases. With the continued movement of the fixed brake block, it pushes the second brake block against the side wall of the inner brake ring, achieving secondary braking of the brake wheel. This allows for a sudden increase in braking force by setting two sets of braking forces, while maintaining a certain buffer.

[0026] The take-up roller can be braked suddenly, which not only provides a certain buffer space to avoid damage to the enameled copper flat wire and thus avoid affecting the quality of the enameled copper flat wire, but also enables the device to stop suddenly, thus avoiding damage to the enameled copper flat wire.

[0027] 2. When the movable sliders are in contact with each other, they can drive the air jet pipe to spray air onto the end of the first brake block. Before the first brake block contacts the inner brake ring, the surface of the inner brake ring can be blown away.

[0028] The surface is covered with dust and impurities to prevent foreign objects from causing slippage at the contact point between the inner brake ring and the first brake block, which would affect the braking effect. When the first brake block contacts the inner brake ring, the air jet from the jet pipe can reduce the temperature at the contact point between the first brake block and the inner brake ring, preventing the first brake block from undergoing high-temperature deformation due to friction with the inner brake ring, which would affect the stability of the first brake block structure and the braking effect on the inner brake ring.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0040] Example

[0041] Reference Figure 1-8An emergency stop protection device for an enameled copper flat wire winding machine includes a winding roller 1, a winding motor 2, and an emergency stop protection mechanism 3. A set of drive rollers 11 that pass through the winding roller 1 are fixedly installed at the center of the winding roller 1. Two sets of symmetrical support frames are provided on the outer side wall of the drive roller 11, and the support frames and the drive roller 11 are rotatably connected by bearings. The winding motor 2 is fixedly connected to the ground through a set of fixed seats, and the output shaft of the winding motor 2 is fixedly connected to the drive roller 11.

[0042] The emergency stop protection mechanism 3 includes a fixed base 37, which is fixedly connected to the ground. A drive motor 32 is fixedly installed on the top of the fixed base 37. A threaded drive roller 34 is fixedly installed at the output end of the drive motor 32. The end of the threaded drive roller 34 away from the drive motor 32 is connected to the fixed base 37 through a set of support frames and bearings and remains rotatable. A brake wheel 31 is fixedly installed at the end of the drive roller 11 that extends to the outside of the take-up roller 1. Two sets of movable sliders 33 are symmetrically arranged on the outer side wall of the threaded drive roller 34 relative to the brake wheel 31. Two sets of fixed brake blocks 35 close to the brake wheel 31 are fixedly installed on the side wall of the movable sliders 33.

[0043] Reference Figure 2-4 On the side where the two sets of movable sliders 33 are close to each other, there is an airtight cavity 333. A rectangular drive slip ring 331 is fitted inside the airtight cavity 333. The part of the rectangular drive slip ring 331 that contacts the inner wall of the airtight cavity 333 is kept sealed. A return spring 332 is fixedly installed between the rectangular drive slip ring 331 and the inside of the airtight cavity 333. A set of air passage connecting pipes 334 that are connected to the inside of the fixed brake block 35 is also fixedly installed on the side wall of the movable slider 33. One end of the air passage connecting pipe 334 is connected to the end of the airtight cavity 333 that is away from the rectangular drive slip ring 331, and the connection is kept sealed.

[0044] A jet pipe 362 is fixedly installed on the side wall of the fixed brake block 35, and a section of the jet pipe 362 extending into the interior of the fixed brake block 35 is connected to one end of the air passage connecting pipe 334 extending into the interior of the fixed brake block 35, and the contact point is kept sealed.

[0045] The outlet of the jet pipe 362 is equipped with a one-way valve. The flow direction of the one-way valve is from the inside of the jet pipe 362 to the outside of the jet pipe 362. The side wall of the movable slider 33 is also equipped with a one-way valve that communicates with the airtight cavity 333. The flow direction of the one-way valve is from the outside of the movable slider 33 to the airtight cavity 333.

[0046] It should be noted that when the movable sliders 33 approach each other, the compressed air inside the airtight chamber 333 can drive the jet pipe 362 to spray air onto the end of the first brake block 360. Before the first brake block 360 contacts the brake inner ring 311, the jet pipe 362 can blow away the dust and impurities attached to the surface of the brake inner ring 311, preventing the presence of foreign objects at the contact point between the brake inner ring 311 and the first brake block 360 from causing slippage and affecting the braking effect. After the first brake block 360 contacts the brake inner ring 311, the jet pipe 362 can reduce the temperature at the contact point between the first brake block 360 and the brake inner ring 311, preventing the first brake block 360 from undergoing high-temperature deformation due to friction with the brake inner ring 311, which would affect the stability of the first brake block 360 structure and the braking effect on the brake inner ring 311.

[0047] Reference Figure 3 The outer wall of the threaded drive roller 34 is provided with threads in the part that contacts the movable slider 33. The movable slider 33 and the threaded drive roller 34 are connected by threads, and the threads on both sides have the same pitch and opposite directions.

[0048] Furthermore, a limiting groove 371 is provided on the top of the fixed base 37, and a limiting fixing block 335 adapted to the limiting groove 371 is fixedly installed on the bottom of the movable slider 33.

[0049] Reference Figure 6 A first sealing oil passage pipe 351 is fixedly installed inside the fixed brake block 35. A first piston push rod 352 is movably sleeved inside the first sealing oil passage pipe 351. A piston is provided at one end of the first piston push rod 352 located inside the first sealing oil passage pipe 351. A tension spring 354 is fixedly installed between the piston and the top of the inner side of the first sealing oil passage pipe 351. A movable ball 353 is provided on the side of the first piston push rod 352 close to the brake wheel 31.

[0050] The fixed brake block 35 also has a second sealing oil passage 355 inside. A second piston push rod 356 is movably connected inside the second sealing oil passage 355. A piston is provided at one end of the second piston push rod 356 inside the second sealing oil passage 355. A limit block 357 is fixedly installed at one end of the second piston push rod 356 outside the second sealing oil passage 355. A second brake block 358 is fixedly installed at one end of the limit block 357 extending to the outside of the second sealing oil passage 355.

[0051] A limiting sleeve 359 is fixedly installed on the side of the fixed brake block 35 close to the brake wheel 31. The first brake block 360 is movably sleeved on the inner side of the limiting sleeve 359. Multiple sets of compression springs 361 are fixedly installed between the first brake block 360 and the fixed brake block 35.

[0052] Furthermore, the brake wheel 31 has a brake inner ring 311 on its side wall, and the second brake block 358 and the first brake block 360 are constructed of rubber material.

[0053] It should be noted that the first sealing oil circuit pipe 351 is connected to the second sealing oil circuit pipe 355 through a set of pipes. The interior of the first sealing oil circuit pipe 351 and the second sealing oil circuit pipe 355, located between the pistons of the first piston push rod 352 and the second piston push rod 356, is filled with hydraulic oil.

[0054] Reference Figure 6 Furthermore, the jet pipe 362 has a curved structure, and the top outlet of the jet pipe 362 faces the top of the first brake block 360.

[0055] It should be noted that the length of the first brake block 360 is greater than the length of the jet pipe 362 extending to the outside of the fixed brake block 35, and the length of the second brake block 358 is less than the length of the first brake block 360.

[0056] Specifically, it can prevent the jet pipe 362 and the second brake block 358 from contacting the brake inner ring 311 before the first brake block 360, thus ensuring the braking effect of the first brake block 360.

[0057] Furthermore, the winding motor 2 is electrically connected to the drive motor 32 and the external control center.

[0058] The working principle of an emergency stop protection device for an enameled copper flat wire winding machine:

[0059] When an emergency occurs on the production line for enameled copper flat wire, the external control center controls the winding motor 2 to shut off and stop driving the winding roller 1 to rotate and wind the enameled copper flat wire. At the same time, the control center controls the drive motor 32 to turn on and start. At this time, the winding roller 1 still has a certain rotational inertia.

[0060] After the drive motor 32 is powered on and started, the rotating shaft of the drive motor 32 drives the threaded transmission roller 34 to rotate. When the threaded transmission roller 34 rotates, it is connected to the movable slider 33 by the thread of the threaded transmission roller 34, which can drive the movable sliders 33 on both sides to move along the movable slider 33.

[0061] The threads move in the direction of contact, and the limiting fixing block 335 and the limiting slide groove 3715 can limit the movement of the movable slider 33 to prevent slippage and displacement.

[0062] The rectangular drive slip rings 331 on both sides first make contact. As the movable sliders 33 on both sides continue to move closer, the rectangular drive slip rings 331 on both sides move towards the interior of the airtight cavity 333, compressing the gas inside the airtight cavity 333. At the same time, the return spring 332 is also compressed. The compressed gas is discharged through the air passage connecting pipe 334 through the end of the airtight cavity 333 and then through the jet pipe 362. This can spray air onto the inner wall of the brake inner ring 311. The air can clean the dust and impurities attached to the side wall of the brake inner ring 311, preventing slippage when the brake inner ring 311 contacts the first brake block 360, which would affect the braking effect.

[0063] As the movable slider 33 moves closer to the brake wheel 31, it also drives the fixed brake blocks 35 on both sides to move towards the brake wheel 31 until the first brake block 360 contacts the inner brake ring 311. As the fixed brake blocks 35 continue to move, the first brake block 360 continues to move towards the inner brake ring 311. The pressure exerted by the first brake block 360 on the inner brake ring 311 gradually increases, thereby increasing the friction between the first brake block 360 and the inner brake ring 311, and increasing the braking force of the first brake block 360 on the inner brake ring 311. As it increases, the compression spring 361 is in a continuously compressed state. The brake wheel 31 is subjected to the frictional resistance between the brake inner ring 311 and the first brake block 360, which can play a good braking and deceleration effect on the brake wheel 31. Through the deceleration braking of the brake wheel 31, the drive roller 11 can be decelerated and braked, which in turn can play a deceleration braking effect on the winding roller 1, preventing the winding roller 1 from continuing to rotate and winding the enameled copper flat wire under the rotational inertia of the drive roller 11, which has stopped production, causing damage to the enameled copper flat wire and resulting in economic losses.

[0064] As the fixed brake block 35 continues to move toward the brake wheel 31, the first piston push rod 352 contacts the brake wheel 31. The sliding friction between the first piston push rod 352 and the brake wheel 31 can be changed into rolling friction through the movable ball 353, which can significantly reduce the friction between the first piston push rod 352 and the brake wheel 31. When the fixed brake block 35 moves toward the brake wheel 31, the brake wheel 31 pushes the first piston push rod 352 toward the first sealing oil passage 351, applying pressure to the hydraulic oil inside the first sealing oil passage 351. At the same time, the tension spring 354 is stretched, increasing the pressure inside the first sealing oil passage 351, which in turn increases the pressure inside the second sealing oil passage 355. Through pressure transmission, the second piston push rod 356 is pushed, which in turn pushes the limit movable block 357 to move, which in turn drives the second brake block 358 to move toward the side wall of the brake inner ring 311 until it contacts and abuts.

[0065] During the movement of the fixed brake block 35 toward the brake wheel 31, the first brake block 360 first contacts the inner brake ring 311. As the fixed brake block 35 continues to move, the first brake block 360 and the inner brake ring 311 are continuously pressed together, and the friction gradually increases. As the fixed brake block 35 continues to move, the fixed brake block 35 can push the first piston push rod 352, which in turn pushes the second brake block 358 to press against the side wall of the inner brake ring 311, thereby achieving secondary braking of the brake wheel 31. By setting two sets of braking forces, the braking force can be suddenly increased. While leaving a certain buffer, the winding roller 1 can be braked urgently. Not only is there a certain buffer space to avoid damage to the enameled copper flat wire, thereby avoiding affecting the quality of the enameled copper flat wire, but it can also achieve an emergency stop of the device to avoid damage to the enameled copper flat wire.

[0066] At the same time, when the movable slider 33 is in contact with each other, it can drive the jet pipe 362 to spray air onto the end of the first brake block 360. Before the first brake block 360 contacts the brake inner ring 311, it can blow away the dust and impurities attached to the surface of the brake inner ring 311, preventing the presence of foreign objects at the contact point between the brake inner ring 311 and the first brake block 360 from causing slippage and affecting the braking effect. When the first brake block 360 contacts the brake inner ring 311, the jet from the jet pipe 362 can reduce the temperature at the contact point between the first brake block 360 and the brake inner ring 311, preventing the first brake block 360 from undergoing high-temperature deformation due to friction with the brake inner ring 311, which would affect the stability of the first brake block 360 structure and the braking effect on the brake inner ring 311.

[0067] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
