Description

Technical Field

[0001] The present invention relates to the technical field of fuse equipment, and specifically to a fuse for a smart power Internet of Things and a method of using the fuse. Background Art

[0002] Fuse is the simplest protective device. When the current exceeds the specified value, the heat generated by the fuse itself can cause the fuse inside the fuse to melt and disconnect the circuit, thereby preventing the power equipment from being damaged by overload and short-circuit current. Fuses can be roughly divided into low-voltage fuses and high-voltage fuses. High-voltage fuses can also be roughly divided into outdoor drop-out fuses, indoor fuses, etc. Smart power boxes are mostly used in outdoor environments, so outdoor drop-out fuses are mostly used.

[0003] However, there are a large number of precision instruments inside the electrical box of the smart power Internet of Things, and outdoor drop-type fuses usually need to burn the internal fuse when encountering a high-load environment. The equipment can only achieve the power-off function after the fuse breaks due to high temperature. In this process, the fuse will arc and the voltage will be extremely unstable, which can easily cause damage to precision equipment. To address the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a fuse for a smart power Internet of Things, including a housing mechanism, the housing mechanism also includes a device housing, a rack track is fixedly connected to the inner wall of the device housing, and a feed box is connected through the bottom of the device housing;

[0005] The fuse mechanism includes a slide plate slidably connected to the inner wall of the rack track, an outer wall of the slide plate is rotatably connected to an electric gear set, and an insulating push frame is fixedly connected to the outer wall of the electric gear set;

[0006] The clamping mechanism comprises a sliding frame slidably connected to the outer wall of the rack track, an extrusion square plate is fixedly connected to the outer wall of the sliding frame, and a pushing rod is fixedly connected to the side wall of the extrusion square plate.

[0007] Preferably, the housing mechanism further comprises an inclined frame fixedly connected to the outer wall of the feed box, a mounting plate is fixedly connected to the outer wall of the feed box, an inclined mounting frame is fixedly connected to the outer wall of the equipment housing, and a plurality of melting rods are placed on the top of the inclined frame. Figure 1 As shown, when the damaged fuse exits the clamping of the power-connecting gear set, it is directly discharged outside the equipment under the influence of the equipment to avoid accumulation inside the equipment and affecting subsequent maintenance.

[0008] Preferably, the shell mechanism also includes a plurality of rotating grooves opened on the outer wall of the mounting plate, and a limiting rotating plate 1 is rotatably connected to the inner wall of the rotating groove, and a reset spring 1 is fixedly connected to the inner wall of the limiting rotating plate 1. When the melting rod breaks, the power-connecting gear set moves downward due to the pulling force of the pulling spring, and a rack track is arranged inside the device, wherein when the power-connecting gear set moves downward, the two gears will rotate at the same time, and the broken melting rod clamped in the power-connecting gear set will be discharged downward, so as to prevent the residual fuse inside from contacting with the external current and causing secondary damage to the equipment.

[0009] Preferably, the fuse mechanism also includes an output terminal fixedly connected to the outer wall of the power-connecting gear set, a push plate fixedly connected to the side wall of the slide plate, a sliding rod fixedly connected to the bottom of the push plate, and a pulling spring fixedly connected to the bottom of the push plate. In order to solve the problem that the fuse cannot quickly cut off the power when burning in a high-voltage environment, a sliding rod and a melting rod are arranged inside the device, wherein the appearance of the melting rod is as follows: Figure 5 In the state shown, when using the equipment, the staff pushes the insulating push frame upward through the insulating rod, forcing the melting rod clamped between the power-connecting gear set to move upward, and finally the top of the melting rod is clamped between the conductive clamping rods, and the thinner position of the top of the melting rod contacts the current output end. When the current input by the equipment is too large, the melting rod heats up and softens, and the pulling spring continuously releases the contraction force during this process. When the melting rod is completely softened due to the high temperature, the sliding rod drives the slide plate to move downward through the pushing plate, and the melting rod is clamped inside the power-connecting gear set. After the melting rod is melted, the power-connecting gear set will drive the bottom of the melting rod to quickly leave the melting position, completing the rapid cutting of the fuse, avoiding subsequent burning and the influence of arc bursting, causing the voltage inside the electric box to be unstable, and causing damage to the precision components inside the electric box.

[0010] Preferably, the fusing mechanism also includes a fixed block fixedly connected to an end of the sliding rod away from the pushing plate, a sliding block is slidably connected to the inner wall of the fixed block, a squeezing spring is fixedly connected to the side wall of the sliding block, a limiting rotating plate 2 is rotatably connected to the inner wall of the sliding block, a baffle is fixedly connected to the inner wall of the sliding block, and an extrusion wheel is rotatably connected to the inner wall of the sliding block. Utilizing the characteristics of the sliding plate and the pushing plate moving up and down, a sliding block and an extrusion spring are arranged at the bottom of the sliding rod. When in use, the sliding block forces the extrusion wheel to move on the outer wall of the melting rod. When the sliding rod moves down, the extrusion wheel rotates clockwise and moves down along the outer wall of the melting rod. When the sliding rod moves up, the extrusion wheel should originally rotate counterclockwise, but during the rotation, the extrusion wheel is restricted by the limiting rotating plate 2, and the limiting rotating plate 2 is restricted by the baffle, which ultimately causes the extrusion wheel to be unable to move. Finally, when the sliding rod moves up, the extrusion wheel clamps the melting rod and moves up synchronously, thereby realizing autonomous loading of the equipment.

[0011] Preferably, the clamping mechanism also includes an airbag fixedly connected to the side wall of the rack track, the inner wall of the airbag is fixedly connected with a return spring 2, the top of the airbag is through-connected with a pressure relief box, the top of the pressure relief box is through-connected with a high-voltage box, the inner wall of the high-voltage box is slidably connected with an outward moving rod, the outer wall of the outward moving rod is fixedly connected with a conductive clamping rod, the inner wall of the rack track is fixedly connected with a pulling plate, the outer wall of the conductive clamping rod is slidably connected with the inner wall of the through hole of the pulling plate, the outer wall of the conductive clamping rod is fixedly connected with a force spring, and the outer wall of the conductive clamping rod is fixedly connected with a force spring. There is an outgoing wire fixedly connected. During the upward movement of the melting rod, the bottom of the melting rod will contact the outer wall of the limiting rotating plate 1. The limiting rotating plate 1 is restricted by the inner wall of the rotating groove and can only rotate upward but not downward. Whenever the extrusion wheel drives the melting rod to move up a certain distance, the bottom of the melting rod will contact the top of the limiting rotating plate 1, ensuring that the position of the melting rod at the bottom remains unchanged when the equipment is powered off, and the power-on gear set will continue to move downward after completing the discharge, and will contact the outer wall of the melting rod, reducing the difficulty of subsequent maintenance by the staff.

[0012] Preferably, the clamping mechanism also includes a slide groove opened on the outer wall of the pressure relief box, a sealing slide is slidably connected to the inner wall of the slide groove, a hydraulic box is fixedly connected to the top of the pressure relief box, an obstruction slide is slidably connected to the inner wall of the hydraulic box, a reset rod is fixedly connected to the top of the obstruction slide, the top of the reset rod is fixedly connected to the bottom of the sealing slide, and a spring is fixedly connected to the outer wall of the reset rod. When the power is restored, the staff pushes the insulating push frame upward through the insulating rod. At this time, the rotation of the power-connecting gear set will drive the melting rod to move upward. Among them, the melting rod will move upward faster because it is simultaneously subjected to the upward movement of the slide and the rotation and squeezing force of the power-connecting gear set. Move, and during the upward movement of the insulating push frame, the extrusion square plate squeezes the airbag, and the air inside the airbag is transported to the pressure relief box and the high-voltage box, forcing the outer moving rod to drive the conductive clamping rod to open to both sides, and the thinner end of the top of the melting rod will pass through the gap of the conductive clamping rod. As the extrusion square plate continues to move upward, the pushing rod will eventually contact the bottom of the sealing slide plate. When the through hole on the sealing slide plate coincides with the pressure relief port of the pressure relief box, the outer moving rod loses its thrust, and the conductive clamping rod generates a contraction force, which eventually causes the conductive clamping rod to quickly clamp the top of the melting rod. Through the application of the above components, when the equipment restores power, equipment damage caused by operating errors can be effectively avoided.

[0013] A fuse for smart power Internet of Things and a method for using the fuse include the following steps:

[0014] S1: When the current input to the device is too large, the melting rod heats up and softens, and the pulling spring continues to release the contraction force. When the melting rod is completely softened due to the high temperature, the sliding rod drives the slide plate to move downward through the push plate;

[0015] S2: When the power-connecting gear set moves downward, the two gears will rotate simultaneously and discharge the broken melted rod clamped inside the power-connecting gear set downward;

[0016] S3: After the discharge is completed, the gear set connected to the power source continues to move downward and contacts the outer wall of the melting rod to complete the loading preparation.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention aims to solve the problem that the fuse cannot be quickly powered off when burning in a high-voltage environment. A sliding rod and a melting rod are arranged inside the device, wherein the shape of the melting rod is as follows: Figure 5 In the state shown, when using the equipment, the staff pushes the insulating push frame upward through the insulating rod, forcing the melting rod clamped between the power-connecting gear set to move upward, and finally the top of the melting rod is clamped between the conductive clamping rods, and the thinner position of the top of the melting rod contacts the current output end. When the current input by the equipment is too large, the melting rod heats up and softens, and the pulling spring continuously releases the contraction force during this process. When the melting rod is completely softened due to the high temperature, the sliding rod drives the slide plate to move downward through the pushing plate, and the melting rod is clamped inside the power-connecting gear set. After the melting rod is melted, the power-connecting gear set will drive the bottom of the melting rod to quickly leave the melting position, completing the rapid cutting of the fuse, avoiding subsequent burning and the influence of arc bursting, causing the voltage inside the electric box to be unstable, and causing damage to the precision components inside the electric box.

[0019] (2) The present invention utilizes the force of the pull spring pulling the power-connecting gear set downward when the melting rod breaks, and a rack track is provided inside the device. When the power-connecting gear set moves downward, the two gears will rotate simultaneously and discharge the broken melting rod clamped inside the power-connecting gear set downward, thereby preventing the residual fuse inside from contacting the external current and causing secondary damage to the device. In addition, since the entire device is in a tilted state, such as Figure 1 As shown, when the damaged fuse exits the clamping of the power-connecting gear set, it is directly discharged outside the equipment under the influence of the equipment to avoid accumulation inside the equipment and affecting subsequent maintenance.

[0020] (3) The present invention utilizes the characteristics of the sliding plate and the pushing plate moving up and down, and a sliding block and an extrusion spring are arranged at the bottom of the sliding rod. When in use, the sliding block forces the extrusion wheel to move on the outer wall of the melting rod. When the sliding rod moves down, the extrusion wheel rotates clockwise and moves down along the outer wall of the melting rod. When the sliding rod moves up, the extrusion wheel should rotate counterclockwise, but during the rotation process, the extrusion wheel is restricted by the limiting rotating plate 2, and the limiting rotating plate 2 is restricted by the baffle plate, which ultimately causes the extrusion wheel to be unable to move. Finally, when the sliding rod moves up, the extrusion wheel clamps the melting rod. The melting rod moves upward synchronously to realize autonomous loading of the equipment. In addition, during the upward movement of the melting rod, the bottom of the melting rod will contact the outer wall of the limiting rotating plate 1. The limiting rotating plate 1 is restricted by the inner wall of the rotating groove and can only rotate upward but not downward. Whenever the extrusion wheel drives the melting rod to move up a certain distance, the bottom of the melting rod will contact the top of the limiting rotating plate 1 to ensure that the position of the melting rod at the bottom remains unchanged when the equipment is powered off, and the power-on gear set will continue to move downward after completing the discharge, and will contact the outer wall of the melting rod, reducing the difficulty of subsequent maintenance by the staff.

[0021] (4) The present invention aims at the common operating error of outdoor drop-out fuses. After being pushed in quickly, the operator retracts the insulating rod without withdrawing the insulating ring, causing the fuse to be pulled open. However, the pulling speed is not fast enough, so a pull-out phenomenon occurs, causing the voltage inside the equipment to be unstable. When the power is restored in the present invention, the operator pushes the insulating push frame upward through the insulating rod. At this time, the rotation of the power-on gear set will drive the melting rod to move upward. Among them, because the melting rod is simultaneously subjected to the upward movement of the slide plate and the rotation and squeezing force of the power-on gear set, it will move upward faster, and on the insulating push frame During the movement, the extrusion square plate squeezes the airbag and transports the air inside the airbag to the pressure relief box and the high-voltage box, forcing the outer moving rod to drive the conductive clamping rod to open to both sides, and the thinner end of the top of the melting rod will pass through the gap of the conductive clamping rod. As the extrusion square plate continues to move upward, the pushing rod will eventually contact the bottom of the sealing slide plate. When the through hole on the sealing slide plate coincides with the pressure relief port of the pressure relief box, the outer moving rod loses its thrust, and the conductive clamping rod generates a contraction force, which eventually causes the conductive clamping rod to quickly clamp the top of the melting rod. Through the application of the above components, the equipment can restore power while effectively avoiding equipment damage caused by operating errors. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figure 1 - Figure 3 The present invention is a fuse for a smart power Internet of Things, comprising a housing mechanism 1, the housing mechanism 1 further comprising a device housing 101, a rack track 102 is fixedly connected to the inner wall of the device housing 101, and a feed box 103 is connected through the bottom of the device housing 101;

[0036] The fuse mechanism 2 includes a slide plate 201 slidably connected to the inner wall of the rack track 102, an electric gear set 202 is rotatably connected to the outer wall of the slide plate 201, and an insulating push frame 203 is fixedly connected to the outer wall of the electric gear set 202;

[0037] The clamping mechanism 3 comprises a sliding frame 301 slidably connected to the outer wall of the rack track 102 , an extrusion square plate 302 is fixedly connected to the outer wall of the sliding frame 301 , and a push rod 303 is fixedly connected to the side wall of the extrusion square plate 302 .

[0038] The housing mechanism 1 further comprises an inclined frame 104 fixedly connected to the outer wall of the feed box 103, a mounting plate 105 fixedly connected to the outer wall of the feed box 103, an inclined mounting frame 106 fixedly connected to the outer wall of the equipment housing 101, and a plurality of melting rods 110 are placed on the top of the inclined frame 104. As the whole equipment is in an inclined state, Figure 1 As shown, after the damaged fuse is released from the clamping of the power supply gear set 202, it is directly discharged from the outside of the device under the influence of the device to avoid accumulation inside the device and affecting subsequent maintenance.

[0039] The housing mechanism 1 also includes a plurality of rotating grooves 107 provided on the outer wall of the mounting plate 105, the inner wall of the rotating groove 107 is rotatably connected with a limiting rotating plate 108, the inner wall of the limiting rotating plate 108 is fixedly connected with a reset spring 109, when the melting rod 110 is broken, the power-connecting gear set 202 moves downward due to the pulling force of the pulling spring 207, a rack track 102 is arranged inside the device, when the power-connecting gear set 202 moves downward, the two gears will rotate at the same time, and the broken melting rod 110 clamped in the power-connecting gear set 202 will be discharged downward, so as to prevent the residual fuse inside from contacting with the external current and causing secondary damage to the device.

[0040] For example 2, please refer to Figure 4 - Fig. 9 The present invention is a fuse for a smart power Internet of Things. On the basis of Example 1, the fuse mechanism 2 also includes an output terminal 204 fixedly connected to the outer wall of the power-connecting gear set 202, a push plate 205 fixedly connected to the side wall of the slide plate 201, a sliding rod 206 fixedly connected to the bottom of the push plate 205, and a pulling spring 207 fixedly connected to the bottom of the push plate 205. In order to solve the problem that the fuse cannot be quickly powered off when burning in a high-voltage environment, a sliding rod 206 and a melting rod 110 are arranged inside the device, wherein the appearance of the melting rod 110 is as follows Figure 5 In the state shown, when using the device, the staff pushes the insulating push frame 203 upwards through the insulating rod, forcing the melting rod 110 clamped between the power-connecting gear set 202 to move upwards, and finally the top of the melting rod 110 is clamped between the conductive clamping rods 309, and the thinner position of the top of the melting rod 110 contacts the current output end. When the current input by the device is too large, the melting rod 110 heats up and softens, and the pulling spring 207 continuously releases the contraction force during this process. When the melting rod 110 is completely softened due to the high temperature, the sliding rod 206 drives the slide plate 201 to move downwards through the pushing plate 205, and the melting rod 110 is clamped inside the power-connecting gear set 202. After the melting rod 110 is blown, the power-connecting gear set 202 will drive the bottom of the melting rod 110 to quickly leave the blown position, completing the rapid cutting of the fuse, avoiding the subsequent burning and the influence of the arc burst, causing the voltage inside the electric box to be unstable, and causing damage to the precision components inside the electric box.

[0041] The fuse mechanism 2 also includes a fixed block 213 fixedly connected to the end of the sliding rod 206 away from the pushing plate 205, a slider 208 is slidably connected to the inner wall of the fixed block 213, a squeezing spring 209 is fixedly connected to the side wall of the slider 208, a limiting rotating plate 210 is rotatably connected to the inner wall of the slider 208, a baffle 211 is fixedly connected to the inner wall of the slider 208, and a squeezing wheel 212 is rotatably connected to the inner wall of the slider 208. By utilizing the characteristics of the sliding plate 201 and the pushing plate 205 moving up and down, a slider 208 and a squeezing spring 209 are arranged at the bottom of the sliding rod 206. When in use, the slider 2 08 forces the extrusion wheel 212 to move on the outer wall of the melting rod 110. When the sliding rod 206 moves downward, the extrusion wheel 212 rotates clockwise and moves downward along the outer wall of the melting rod 110. When the sliding rod 206 moves upward, the extrusion wheel 212 should rotate counterclockwise, but during the rotation, the extrusion wheel 212 is restricted by the limiting turn plate 210, and the limiting turn plate 210 is restricted by the baffle 211, which ultimately makes the extrusion wheel 212 unable to move. Finally, when the sliding rod 206 moves upward, the extrusion wheel 212 clamps the melting rod 110 and moves upward synchronously, thereby realizing autonomous loading of the equipment.

[0042] The clamping mechanism 3 also includes an airbag 304 fixedly connected to the side wall of the rack track 102, a return spring 305 fixedly connected to the inner wall of the airbag 304, a pressure relief box 306 connected to the top of the airbag 304, a high-voltage box 307 connected to the top of the pressure relief box 306, an outer moving rod 308 slidably connected to the inner wall of the high-voltage box 307, a conductive clamping rod 309 fixedly connected to the outer wall of the outer moving rod 308, a pulling plate 317 fixedly connected to the inner wall of the rack track 102, the outer wall of the conductive clamping rod 309 is slidably connected to the inner wall of the through hole of the pulling plate 317, a force spring 310 fixedly connected to the outer wall of the conductive clamping rod 309, and the conductive clamping rod 3 09 is fixedly connected with an outgoing wire 311. During the upward movement of the melting rod 110, the bottom of the melting rod 110 will contact the outer wall of the limiting rotating plate 108. The limiting rotating plate 108 is restricted by the inner wall of the rotating groove 107 and can only rotate upward but not downward. Whenever the extrusion wheel 212 drives the melting rod 110 to move up a certain distance, the bottom of the melting rod 110 will contact the top of the limiting rotating plate 108, ensuring that the position of the melting rod 110 at the bottom remains unchanged when the equipment is powered off, and the power-on gear set 202 continues to move downward after completing the discharge, and will contact the outer wall of the melting rod 110, reducing the difficulty of subsequent maintenance by the staff.

[0043] The clamping mechanism 3 also includes a slide groove 312 opened on the outer wall of the pressure relief box 306, and a sealing slide plate 313 is slidably connected to the inner wall of the slide groove 312. The top of the pressure relief box 306 is fixedly connected to a hydraulic box 314, and an obstruction slide plate 315 is slidably connected to the inner wall of the hydraulic box 314. A reset rod 316 is fixedly connected to the top of the obstruction slide plate 315. The top of the reset rod 316 is fixedly connected to the bottom of the sealing slide plate 313, and a spring is fixedly connected to the outer wall of the reset rod 316. When the power is restored, the staff pushes the insulating push frame 203 upward through the insulating rod. At this time, the rotation of the power-connecting gear set 202 will drive the melting rod 110 to move upward. Among them, because the melting rod 110 is simultaneously subjected to the upward movement of the slide plate 201 and the rotation and squeezing force of the power-connecting gear set 202, it will move upward faster. The outer moving rod 308 drives the conductive clamping rod 309 to open to both sides, and the thinner end of the top of the melting rod 110 will pass through the gap of the conductive clamping rod 309. As the square plate 302 is continuously moved upward, the pushing rod 303 finally contacts the bottom of the sealing slide plate 313. When the through hole on the sealing slide plate 313 coincides with the pressure relief port of the pressure relief box 306, the outer moving rod 308 loses its thrust, and the conductive clamping rod 309 generates a contraction force, which eventually causes the conductive clamping rod 309 to quickly clamp the top of the melting rod 110. By applying the above components, when the equipment restores power, equipment damage caused by operating errors can be effectively avoided.

[0044] The manufacturing method of the manufacturing device comprises the following steps:

[0045] S1: When the current input to the device is too large, the melting rod 110 heats up and softens, and the pulling spring 207 continuously releases the contraction force. When the melting rod 110 is completely softened due to the high temperature, the sliding rod 206 drives the sliding plate 201 to move downward through the pushing plate 205;

[0046] S2: When the power-connecting gear set 202 moves downward, the two gears will rotate simultaneously and discharge the broken melted rod 110 clamped inside the power-connecting gear set 202 downward;

[0047] S3: After completing the material discharge, the gear set 202 continues to move downward and contacts the outer wall of the melting rod 110 to complete the material loading preparation.

[0048] A specific application of this embodiment is: the present invention aims at the problem that the fuse cannot be quickly cut off when burning in a high-voltage environment. A sliding rod 206 and a melting rod 110 are arranged inside the device, wherein the shape of the melting rod 110 is as follows: Figure 5In the state shown, when the device is used, when the power is restored, the staff pushes the insulating push frame 203 upward through the insulating rod, and the rotation of the power-connecting gear set 202 will drive the melting rod 110 to move upward. In this case, the melting rod 110 will move upward faster because it is simultaneously subjected to the upward movement of the slide plate 201 and the rotation and squeezing force of the power-connecting gear set 202. During the upward movement of the insulating push frame 203, the squeezing square plate 302 squeezes the air bag 304, and the air inside the air bag 304 is transported to the pressure relief box 306 and the high-voltage box 306. 07, forcing the outer rod 308 to drive the conductive clamping rod 309 to open to both sides, and the thinner end of the top of the melting rod 110 will pass through the gap of the conductive clamping rod 309. As the extrusion square plate 302 continues to move upward, the push rod 303 will eventually contact the bottom of the sealing slide plate 313. When the through hole on the sealing slide plate 313 coincides with the pressure relief port of the pressure relief box 306, the outer rod 308 loses its thrust, and the conductive clamping rod 309 generates a contraction force, causing the conductive clamping rod 309 to quickly clamp the top of the melting rod 110, and finally the melting rod 110 is The top of the melting rod 110 is clamped between the conductive clamping rods 309, and the thinner part of the top of the melting rod 110 contacts the current output end. When the current input to the device is too large, the melting rod 110 heats up and softens, and the pulling spring 207 continuously releases the contraction force during this process. When the melting rod 110 is completely softened due to the high temperature, the sliding rod 206 drives the slide plate 201 to move downward through the push plate 205, and the melting rod 110 is clamped inside the power-connecting gear set 202. After the melting rod 110 is melted, the power-connecting gear set 202 will drive the melting rod 110 to melt. The bottom of the rod 110 quickly leaves the blown position to quickly cut off the fuse. When the melting rod 110 is broken, the power-connecting gear set 202 moves downward due to the pulling force of the pulling spring 207. A rack track 102 is provided inside the device. When the power-connecting gear set 202 moves downward, the two gears rotate at the same time and the broken melting rod 110 clamped in the power-connecting gear set 202 is discharged downward to prevent the residual fuse inside from contacting with the external current and causing secondary damage to the device. In addition, since the overall device is in an inclined state, such as Figure 1As shown, after the damaged fuse is released from the clamping of the power-connecting gear set 202, it is directly discharged from the outside of the equipment under the influence of the equipment to avoid accumulation inside the equipment and affecting subsequent maintenance. By utilizing the characteristics of the sliding plate 201 and the pushing plate 205 moving up and down, a slider 208 and an extrusion spring 209 are arranged at the bottom of the sliding rod 206. When in use, the slider 208 forces the extrusion wheel 212 to move on the outer wall of the melting rod 110. When the sliding rod 206 moves down, the extrusion wheel 212 rotates clockwise and moves down along the outer wall of the melting rod 110. When the sliding rod 206 moves up, the extrusion wheel 212 should rotate counterclockwise. However, during the rotation, the extrusion wheel 212 is restricted by the limiting rotating plate 210, and the limiting rotating plate 210 is restricted by the baffle 211, which eventually leads to extrusion. The pressing wheel 212 cannot move. Finally, when the sliding rod 206 moves upward, the extrusion wheel 212 clamps the melting rod 110 and moves upward synchronously, thereby realizing autonomous feeding of the equipment. In addition, during the upward movement of the melting rod 110, the bottom of the melting rod 110 will contact the outer wall of the limiting rotating plate 108. The limiting rotating plate 108 is restricted by the inner wall of the rotating groove 107 and can only rotate upward but cannot rotate downward. Whenever the extrusion wheel 212 drives the melting rod 110 to move up a certain distance, the bottom of the melting rod 110 will contact the top of the limiting rotating plate 108, thereby ensuring that the position of the melting rod 110 at the bottom remains unchanged when the equipment is powered off, and the power-on gear set 202 continues to move downward after completing the discharge, and will contact the outer wall of the melting rod 110, thereby reducing the difficulty of subsequent maintenance for the staff.
