Description

Technical Field

[0001] This invention relates to the field of metal wire drawing, specifically to a nickel-chromium wire winding and straightening device. Background Technology

[0002] During the manufacturing process, nickel-chromium wire needs to be wound up for easy storage, transportation, and use. A winding and straightening device is a piece of equipment used to wind and collect the wire, designed to ensure uniform and orderly winding for subsequent production processes.

[0003] Patent publication number CN218088402U relates to a take-up device for nickel-chromium wire drawing production, including a tension adjustment mechanism, a wire laying mechanism, a first take-up roller, and a second take-up roller. The tension adjustment mechanism is located above the first take-up roller, the wire laying mechanism is located to the right of the first take-up roller, and the second take-up roller is located to the right of the wire laying mechanism. During operation, the first take-up roller is used for both take-up and release, avoiding the influence of the previous process on the take-up process. In the tension adjustment mechanism, the tension of the nickel-chromium wire take-up can be quickly adjusted by rotating the position of the counterweight on the balance bar, both with high working efficiency. In the wire laying mechanism, a linear motor drives the wire laying roller to move along the axial direction of the second take-up roller, so that the nickel-chromium wire moves along the axial direction of the second take-up roller, thereby evenly distributing it on the second take-up roller, effectively improving the quality and appearance of the product.

[0004] In the aforementioned patent, the first take-up roller is used to avoid the influence of the previous process on the take-up process, so that the material can be evenly distributed on the second take-up roller, which effectively improves the quality and appearance of the product. However, during the winding process of nickel-chromium wire, if the take-up roller is not effectively fixed, the motor may start prematurely due to accidental contact, which will affect the winding of nickel-chromium wire. Therefore, a nickel-chromium wire winding and straightening device with protective function is designed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a nickel-chromium wire winding and straightening device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nickel-chromium wire winding and straightening device, comprising a platform, an anti-accidental contact device, and an anti-breakage device; wherein, a motor is fixedly installed above the platform, a drive shaft is fixedly installed at the output end of the motor, a support plate is fixedly installed above the platform, and a reciprocating lead screw rotates through the support plate, the reciprocating lead screw being connected to the drive shaft via a transmission belt; wherein, the anti-accidental contact device comprises a connector, a rotating rod, a receiving platform, a buckle plate, a slider, and a button, wherein a winding sleeve is fixedly installed on the surface of the rotating rod, the rotating rod is then placed above the support plate, the buckle plate is rotated to limit the rotation of the rotating rod, and the buckle plate rotates to contact and press the slider to move. The connector is fixedly installed at the end of the drive shaft away from the motor. The rotating rod is hinged to the surface of the connector. The receiving platform is fixedly installed above the support plate. The buckle plate is hinged to the surface of the receiving platform. The slider is slidably installed above the support plate. The button is fixedly installed above the support plate. The slider has a beveled surface on its top and a limit groove on its surface. The button is electrically connected to the motor. A spring is provided between the slider and the support plate. After the slider moves, it resets under the action of the spring to limit the buckle plate. After the slider moves, it contacts the button to limit its movement. This effectively prevents the motor from being accidentally started when the rotating rod is not limited, thus avoiding affecting the winding operation.

[0007] According to the above technical solution, a limiting rod is slidably installed on the surface of the slider, and a second limiting groove is opened on the surface of the support plate. The limiting rod moves downward and enters the interior of the first limiting groove on the surface of the support plate, thereby fixing the slider and preventing the slider from shifting during the winding process, which would cause it to release the limiting of the buckle plate and thus affect the winding work, thereby improving work efficiency.

[0008] According to the above technical solution, the anti-breakage device includes a sleeve, a limiting frame, a fixing plate, a sliding block, and a moving rod. The joint rotation drives the rotating rod to rotate, and the transmission shaft rotation drives the reciprocating screw to rotate via a transmission belt. The reciprocating screw rotation drives the sleeve to reciprocate. The sleeve is slidably mounted on the surface of the reciprocating screw. The limiting frame is fixedly mounted on the surface of the sleeve. A groove is formed on the surface of the limiting frame. The fixing plate is fixedly mounted inside the groove. The sliding block is slidably mounted inside the groove. The moving rod is slidably mounted on the surface of the support plate. The moving rod slides through the left and right walls of the sliding block. The sliding block and the fixing plate are fixedly connected by a spring. The reciprocating motion of the sleeve drives the reciprocating motion of the limiting frame to achieve the winding of the nichrome wire. When the tension on the nichrome wire is too high, the nichrome wire will squeeze the sliding block to move closer to the winding sleeve, thereby reducing the tension on the nichrome wire and preventing the nichrome wire from breaking due to excessive tension.

[0009] According to the above technical solution, a connecting rod is fixedly installed on the surface of the moving rod, and an arc-shaped plate is fixedly installed at the end of the connecting rod away from the moving rod. A second spring is provided between the moving rod and the support plate. The movement of the connecting rod drives the arc-shaped plate to move. The arc-shaped plate moves to contact and squeeze the winding sleeve. By increasing the friction, the rotation speed of the winding sleeve is slowed down, further reducing the tension on the nickel-chromium wire during winding and reducing subsequent maintenance costs.

[0010] According to the above technical solution, it also includes a tightening device and a disconnection device. The tightening device includes a receiving plate, a U-shaped block, a telescopic spring rod, a rotating rod, and a fixed rod. During the winding process of the nichrome wire, it contacts and drives the rotating rod to rotate. The rotating rod rotates into the movement trajectory of the limiting frame. The movement of the limiting frame drives the rotating rod to move, and the movement of the rotating rod drives the telescopic spring rod to move. The receiving plate is fixedly installed above the platform. The U-shaped block is slidably installed above the receiving plate. The telescopic spring rod is fixedly installed above the U-shaped block. The rotating rod is hinged to the free end of the telescopic spring rod. The fixed rod is fixedly installed at the free end of the telescopic spring rod. A second sliding groove is opened on the surface of the fixed end of the telescopic spring rod. A third spring is provided between the rotating rod and the free end of the telescopic spring rod. The movement of the telescopic spring rod drives the U-shaped block to slide on the surface of the receiving plate, so that the fixed rod can always keep the nichrome wire and the winding sleeve tightly fitted, making the nichrome wire winding tighter and improving the winding effect.

[0011] According to the above technical solution, a push rod is rotatably mounted on the surface of the rotating rod, and a sliding groove three is opened on the surface of the telescopic spring rod. A receiving rod is slidably mounted inside the sliding groove three. The end of the push rod away from the rotating rod is rotatably connected to the receiving rod. A lifting rod is fixedly mounted on the surface of the receiving rod, and a clamp is slidably mounted on the surface of the fixed rod. The end of the lifting rod away from the receiving rod is fixedly connected to the clamp. When the lifting rod moves downward, it drives the clamp to move downward. The downward movement of the clamp clamps and fixes the nichrome wire, preventing the last section of nichrome wire from failing to fit with the take-up sleeve, causing the nichrome wire to become tangled and increasing subsequent maintenance costs.

[0012] According to the above technical solution, the disconnection device includes a placement plate, a gate, a sliding rod, a pressure rod, a fixing block, and a connecting rod. The rotating rod rotates, causing the fixing block to move downwards. The downward movement of the fixing block causes the connecting rod to move downwards. The downward movement of the connecting rod causes the pressure rod to move downwards. The downward movement of the pressure rod causes the sliding rod to move downwards. The placement plate is fixedly installed on the surface of the fixed end of the telescopic spring rod. The gate is fixedly installed on the surface of the placement plate. A four-slide groove is formed on the surface of the placement plate. The sliding rod is slidably installed inside the four-slide groove. The pressure rod is fixedly installed on the surface of the sliding rod. The fixing block is fixedly installed below the rotating rod. The connecting rod is hinged below the fixing block. The end of the connecting rod away from the fixing block is hinged to the pressure rod. The gate is electrically connected to the motor. The pressure rod moves downwards to contact and squeeze the gate to rotate. The rotation of the gate disconnects the circuit, causing the motor to stop working. This effectively prevents the nichrome wire from detaching from the chuck after the nichrome wire winding is completed, which would cause the nichrome wire to become tangled and increase subsequent maintenance costs.

[0013] According to the above technical solution, a U-shaped rod is slidably installed on the surface of the telescopic spring rod. The U-shaped rod contacts the gate. The surface of the U-shaped rod is cut into a bevel. A spring-loaded spring is provided between the U-shaped rod and the telescopic spring rod. When the pressure rod moves downward, it will first contact and squeeze the U-shaped rod to move. The movement of the U-shaped rod will release the limit on the gate. This can effectively prevent the gate from rotating and shutting down the motor due to foreign objects during operation, thereby reducing the winding efficiency.

[0014] This invention provides a nickel-chromium wire winding and straightening device. It has the following beneficial effects:

[0015] (1) The nickel-chromium wire winding and straightening device fixes the winding sleeve on the surface of the rotating rod, then rotates the rotating rod to place it on the surface of the support plate, and then rotates the buckle plate. The buckle plate moves to contact and squeeze the slider and is limited under its action. The slider moves to release the limit on the button. Then the motor is started by the button to start the winding work. It can effectively avoid the winding work being affected by accidental start of the motor when the rotating rod is not limited. After the slider is limited by the buckle plate, it moves the limit rod downward. The limit rod enters the limit groove to fix the slider, avoiding the slider from shifting during the winding process and affecting the winding work, thus improving work efficiency.

[0016] (2) The nichrome wire winding and straightening device starts the motor. The output end of the motor drives the rotating rod and the reciprocating screw to rotate through the transmission shaft and transmission belt to realize the winding of the nichrome wire. During the winding process, when the tension of the nichrome wire is too large, the nichrome wire will squeeze the slider and the moving rod to move closer to the winding sleeve, so that the tension of the nichrome wire is reduced and the nichrome wire is prevented from breaking due to excessive tension. At the same time, the moving rod moves the connecting rod and the arc plate to move and contact the winding sleeve. By increasing the friction, the rotation speed of the winding sleeve is slowed down, further reducing the tension of the nichrome wire during winding and reducing the subsequent maintenance cost.

[0017] (3) In this nichrome wire winding and straightening device, the nichrome wire contacts and squeezes the rotating rod during the winding process, causing the sleeve and the limiting frame to drive the telescopic spring rod to move back and forth. At the same time, the nichrome wire is tightly attached to the winding sleeve under the action of the fixed rod, making the nichrome wire winding tighter and improving the winding effect. At the same time, when the last section of the nichrome wire is separated from the rotating rod, the rotating rod resets and is separated from the limiting frame to stop moving. At the same time, the push rod and the lifting rod drive the clamp to move downward to clamp and fix the nichrome wire, so as to avoid the last section of the nichrome wire being unable to fit with the winding sleeve, causing the nichrome wire to be scattered and increasing the subsequent maintenance cost.

[0018] (4) In this nickel-chromium wire winding and straightening device, the rotating rod rotates and resets, driving the sliding rod and pressure rod to move downward through the fixed block and connecting rod. The pressure rod moves downward to contact and squeeze the gate, causing it to rotate and disconnect the circuit, so that the motor stops working. This can effectively prevent the nickel-chromium wire from falling off the clamp after the nickel-chromium wire winding is completed, which would lead to the nickel-chromium wire becoming scattered and increasing subsequent maintenance costs. The pressure rod moves downward and first contacts and squeezes the U-shaped rod to move. The movement of the U-shaped rod releases the limit on the gate, which can effectively prevent the gate from rotating and shutting down the motor due to foreign objects during the operation, thereby reducing the winding efficiency.

[0028] 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.

[0029] Please see Figure 1-5One embodiment of the present invention is as follows: a nickel-chromium wire winding and straightening device, including a platform 1, an anti-accidental contact device, and an anti-breakage device; wherein, a motor is fixedly installed above the platform 1, a drive shaft 2 is fixedly installed at the output end of the motor, a support plate 3 is fixedly installed above the platform 1, a reciprocating lead screw 4 rotatably passes through the support plate 3, and the reciprocating lead screw 4 is connected to the drive shaft 2 by a drive belt; wherein, the anti-accidental contact device includes a connector 51, a rotating rod 52, a receiving platform 53, a buckle plate 54, a slider 55, and a button 56, a winding sleeve is fixedly installed on the surface of the rotating rod 52, then the rotating rod 52 is placed above the support plate 3, the buckle plate 54 is rotated to limit the rotating rod 52, the buckle plate 54 rotates to contact and squeeze the slider 55 to move, the connector 51 is fixedly installed at the end of the drive shaft 2 away from the motor, and the rotating rod 52 is hinged to the connector 51. The receiving platform 53 is fixedly installed above the support plate 3. The buckle plate 54 is hinged to the surface of the receiving platform 53. The slider 55 is slidably installed above the support plate 3. The button 56 is fixedly installed above the support plate 3. The top of the slider 55 is cut with a bevel. The surface of the slider 55 is provided with a limit groove. The button 56 is electrically connected to the motor. A spring is provided between the slider 55 and the support plate 3. When the rotating rod 52 and the winding sleeve rotate, the nichrome wire can be wound up. At the same time, the edge of the winding sleeve can straighten the nichrome wire and prevent the nichrome wire from falling off the winding sleeve. After the slider 55 moves, it resets under the action of the spring and limits the buckle plate 54. After the slider 55 moves, it contacts the limit of the button 56. This can effectively prevent the motor from being accidentally started when the rotating rod 52 is not limited, thus affecting the winding operation.

[0030] A limiting rod 57 is slidably mounted on the surface of the slider 55, and a second limiting groove is opened on the surface of the support plate 3. The limiting rod 57 moves downward and enters the interior of the first limiting groove on the surface of the support plate 3, thereby fixing the slider 55 and preventing the slider 55 from shifting during the winding process, which would cause it to release the limiting of the buckle plate 54 and thus affect the winding work, thereby improving work efficiency.

[0031] The anti-breakage device includes a sleeve 61, a limiting frame 62, a fixing plate 63, a sliding block 64, and a moving rod 65. The joint 51 rotates, causing the rotating rod 52 to rotate. The drive shaft 2 rotates, driving the reciprocating screw 4 to rotate via a drive belt. The rotation of the reciprocating screw 4 causes the sleeve 61 to reciprocate. The sleeve 61 is slidably mounted on the surface of the reciprocating screw 4. The limiting frame 62 is fixedly mounted on the surface of the sleeve 61. A groove is formed on the surface of the limiting frame 62. The fixing plate 63 is fixedly mounted inside the groove. The sliding block 64 is slidably mounted inside the groove. The moving rod 65 is slidably mounted on the surface of the support plate 3. The moving rod 65 slides through the left and right walls of the sliding block 64. The sliding block 64 and the fixing plate 63 are fixedly connected by a spring. The reciprocating motion of the sleeve 61 drives the reciprocating motion of the limiting frame 62 to achieve the winding of the nichrome wire. When the tension on the nichrome wire is too high, the nichrome wire will squeeze the sliding block 64 and move it closer to the winding sleeve, thereby reducing the tension on the nichrome wire and preventing the nichrome wire from breaking due to excessive tension.

[0032] A connecting rod 66 is fixedly installed on the surface of the moving rod 65. An arc-shaped plate 67 is fixedly installed at the end of the connecting rod 66 away from the moving rod 65. A spring-loaded spring is provided between the moving rod 65 and the support plate 3. The movement of the connecting rod 66 drives the arc-shaped plate 67 to move. The arc-shaped plate 67 moves to contact and squeeze the winding sleeve. By increasing the friction, the rotation speed of the winding sleeve is slowed down, further reducing the tension on the nickel-chromium wire during winding and reducing subsequent maintenance costs.

[0033] In this embodiment, the take-up sleeve is fixedly installed on the surface of the rotating rod 52. Then, the rotating rod 52 is placed above the support plate 3. The buckle plate 54 is rotated to limit the rotating rod 52. The buckle plate 54 rotates to contact and press the slider 55 to move. After the slider 55 moves, it resets under the action of the spring and limits the buckle plate 54. After the slider 55 moves, it contacts the button 56 to limit it. This effectively prevents the motor from being accidentally started when the rotating rod 52 is not limited, which would affect the winding operation. After the slider 55 limits the rotating rod 52, the limiting rod 57 moves downward and enters the limiting groove on the surface of the support plate 3. This fixes the slider 55 and prevents it from shifting during the winding operation, which would cause it to release the limit on the buckle plate 54 and affect the winding operation, thus improving work efficiency.

[0034] After the motor is started, the output end of the motor drives the transmission shaft 2 to rotate. The rotation of the transmission shaft 2 drives the joint 51 to rotate, and the rotation of the joint 51 drives the rotating rod 52 to rotate. The rotation of the transmission shaft 2 drives the reciprocating screw 4 to rotate through the transmission belt. The rotation of the reciprocating screw 4 drives the sleeve 61 to reciprocate. The reciprocating motion of the sleeve 61 drives the limit frame 62 to reciprocate, thereby achieving the winding of the nichrome wire. When the tension on the nichrome wire is too high, the nichrome wire will squeeze the sliding block 64 and move towards the winding sleeve, thereby reducing the tension on the nichrome wire and preventing the nichrome wire from breaking due to excessive tension. At the same time, the movement of the sliding block 64 drives the moving rod 65 to move, and the movement of the moving rod 65 drives the connecting rod 66 to move. The movement of the connecting rod 66 drives the arc plate 67 to move. The arc plate 67 moves to contact and squeeze the winding sleeve, thereby increasing the friction to slow down the rotation speed of the winding sleeve, further reducing the tension on the nichrome wire during winding and reducing subsequent maintenance costs.

[0035] Please see Figure 1-8 Based on the above embodiments, another embodiment of the present invention further includes a tightening device and a disconnection device. The tightening device includes a receiving plate 71, a U-shaped block 72, a telescopic spring rod 73, a rotating rod 74, and a fixing rod 75. During the winding process of the nichrome wire, the rotating rod 74 is contacted and rotated. The rotating rod 74 rotates into the movement trajectory of the limiting frame 62. The movement of the limiting frame 62 causes the rotating rod 74 to move, and the movement of the rotating rod 74 causes the telescopic spring rod 73 to move. The receiving plate 71 is fixedly installed above the platform 1, and the U-shaped block 72 is slidably installed on the receiving plate 71. Above the U-shaped block 72, a telescopic spring rod 73 is fixedly installed above the telescopic spring rod 73. A rotating rod 74 is hinged to the free end of the telescopic spring rod 73. A fixed rod 75 is fixedly installed at the free end of the telescopic spring rod 73. A second groove is provided on the surface of the fixed end of the telescopic spring rod 73. A third spring is provided between the rotating rod 74 and the free end of the telescopic spring rod 73. The movement of the telescopic spring rod 73 causes the U-shaped block 72 to slide on the surface of the receiving plate 71, so that the fixed rod 75 can always keep the nickel-chromium wire and the winding sleeve in close contact, making the nickel-chromium wire more tightly wound and improving the winding effect.

[0036] A push rod 76 is rotatably mounted on the surface of the rotating rod 74. A groove 3 is formed on the surface of the telescopic spring rod 73. A receiving rod 77 is slidably mounted inside the groove 3. The end of the push rod 76 away from the rotating rod 74 is rotatably connected to the receiving rod 77. A lifting rod 78 is fixedly mounted on the surface of the receiving rod 77. A clamp 79 is slidably mounted on the surface of the fixing rod 75. The end of the lifting rod 78 away from the receiving rod 77 is fixedly connected to the clamp 79. When the lifting rod 78 moves downward, it causes the clamp 79 to move downward. The downward movement of the clamp 79 clamps and fixes the nichrome wire, preventing the last section of nichrome wire from failing to adhere to the take-up sleeve, causing the nichrome wire to become tangled and increasing subsequent maintenance costs.

[0037] The disconnection device includes a placement plate 81, a gate 82, a sliding rod 83, a pressure rod 84, a fixing block 85, and a connecting rod 86. The rotating rod 74 rotates, causing the fixing block 85 to move downwards. The downward movement of the fixing block 85 causes the connecting rod 86 to move downwards. The downward movement of the connecting rod 86 causes the pressure rod 84 to move downwards. The downward movement of the pressure rod 84 causes the sliding rod 83 to move downwards. The placement plate 81 is fixedly installed on the surface of the fixed end of the telescopic spring rod 73. The gate 82 is fixedly installed on the surface of the placement plate 81. A sliding groove is formed on the surface of the placement plate 81. The sliding rod 83 is slidably installed on... Inside the slide rail 4, the pressure rod 84 is fixedly installed on the surface of the sliding rod 83, the fixing block 85 is fixedly installed below the rotating rod 74, and the connecting rod 86 is hinged below the fixing block 85. The end of the connecting rod 86 away from the fixing block 85 is hinged to the pressure rod 84. The gate 82 is electrically connected to the motor. The pressure rod 84 moves downward to contact and squeeze the gate 82 to rotate. The rotation of the gate 82 disconnects the circuit, causing the motor to stop working. This effectively prevents the nichrome wire from detaching from the chuck 79 after the nichrome wire is wound up, which would cause the nichrome wire to become tangled and increase subsequent maintenance costs.

[0038] A U-shaped rod 87 is slidably mounted on the surface of the telescopic spring rod 73. The U-shaped rod 87 contacts the gate 82. The surface of the U-shaped rod 87 is cut into a bevel. A spring-loaded spring 4 is installed between the U-shaped rod 87 and the telescopic spring rod 73. When the pressure rod 84 moves downward, it will first contact and squeeze the U-shaped rod 87 to move. The movement of the U-shaped rod 87 will release the limit on the gate 82, which can effectively prevent the gate 82 from rotating and shutting down the motor due to foreign objects during operation, thereby reducing the winding efficiency.

[0039] In this embodiment, during the winding process, the nichrome wire contacts and drives the rotating rod 74 to rotate. The rotating rod 74 rotates into the movement trajectory of the limiting frame 62. The movement of the limiting frame 62 drives the rotating rod 74 to move, which in turn drives the telescopic spring rod 73 to move. The movement of the telescopic spring rod 73 drives the fixing rod 75 to move, which in turn causes the U-shaped block 72 to slide on the surface of the receiving plate 71. This ensures that the fixing rod 75 can always keep the nichrome wire and the winding sleeve in close contact, resulting in a tighter winding of the nichrome wire and improving the winding efficiency. As a result, when the last end of the nichrome wire disengages from the rotating rod 74, the rotating rod 74 rotates and resets under the action of the spring 3. The rotation of the rotating rod 74 drives the push rod 76 to move downward, the push rod 76 moves downward, the receiving rod 77 moves downward, the receiving rod 77 moves downward, the lifting rod 78 moves downward, the lifting rod 78 moves downward, the clamp 79 moves downward, and the clamp 79 clamps and fixes the nichrome wire, preventing the last section of nichrome wire from failing to fit with the winding sleeve, causing the nichrome wire to become tangled and increasing subsequent maintenance costs.

[0040] The rotation of the rotating rod 74 causes the fixed block 85 to move downwards. The downward movement of the fixed block 85 causes the connecting rod 86 to move downwards. The downward movement of the connecting rod 86 causes the pressure rod 84 to move downwards. The downward movement of the pressure rod 84 causes the sliding rod 83 to move downwards. During the movement of the sliding rod 83, it enters the upper part of the gate 82 under the action of the sliding groove 4. Then the pressure rod 84 moves downwards to contact and squeeze the gate 82 to rotate. The rotation of the gate 82 disconnects the circuit, causing the motor to stop working. This effectively prevents the nichrome wire from detaching from the chuck 79 after the nichrome wire winding is completed, which would cause the nichrome wire to become tangled and increase subsequent maintenance costs. The downward movement of the pressure rod 84 will first contact and squeeze the U-shaped rod 87 to move. The movement of the U-shaped rod 87 will release the limit on the gate 82. This effectively prevents the gate 82 from rotating and shutting down the motor due to foreign objects during operation, thereby reducing the winding efficiency.
