Description

Technical Field

[0001] This invention relates to an intelligent induction heating device that facilitates the replacement of heating rods and its usage method. Background Technology

[0002] The heating equipment is a device composed of heating elements and accessories. A glass fiber reinforced refractory fiber layer is wound around a multi-strand resistance wire, and a metal wire reinforced refractory fiber layer is woven outside the refractory fiber layer. The double-layer covering layer, which is tightly combined and distributed along the entire length of the resistance wire, together with the central resistance wire, forms an integral direct heating unit that can be bent at will and can be in close contact with the object being heated. The heating unit is repeatedly wound into a strip shape according to the shape and size of the object being heated. Then, multiple parallel units are horizontally woven together with metal wire to form a braided high-temperature electric heater that can be directly wrapped around the object being heated and used immediately. It can be used as soon as the power is turned on.

[0003] To increase the contact area with the heated material, the heat output terminal of most heating devices is rod-shaped. The lifespan of a heating rod is generally no more than two years. After prolonged use, problems such as wire aging, contact oxidation, and temperature sensor malfunction are prone to occur, requiring periodic replacement. Replacement requires rotating the heating rod to unscrew the threaded component from the mounting slot. However, in actual replacement, if the worker does not support the bottom of the heating rod during disassembly, the mounting slot no longer restrains the heating rod as the threaded component unscrews, causing it to fall to the ground under gravity. This can lead to the quartz or glass tube on the surface of the heating rod shattering, compromising the device's safety. Therefore, we propose an intelligent induction heating device and its usage method that facilitates heating rod replacement. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides an intelligent induction heating device and its usage method that facilitates the replacement of heating rods. Through the design of a mounting base, mounting groove, and rotating shaft, the heating rod, after being removed from the threaded mounting groove, can remain inside the heating rod slot. By rotating the heating rod slot, the rotating shafts on both sides of the slot release the restriction mechanism and rotate under the constraint of the mounting grooves on both sides. The heating rod can rotate together with the heating rod slot to an inclined state, making it convenient for workers to remove. When multiple heating rods need to be replaced, workers can rotate and remove all heating rods at once, and then remove them from the heating rod slots afterward. This facilitates coordinated workflow among multiple workers, improving the convenience of using and maintaining the device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an intelligent induction heating device that facilitates the replacement of heating rods, comprising a base, a top plate, threaded mounting slots, and heating rods. The top plate is provided above the base, and the bottom end of the top plate is provided with several sets of threaded mounting slots. Heating rods are installed inside the threaded mounting slots.

Sliding grooves are opened on both sides of the adjustment groove, and sliders are slidably arranged in the sliding grooves. Both sets of sliders pass through the sliding grooves and are connected to the push block. The bottom of the inner wall of the mounting base is provided with a slot, and the slot passes through the mounting base and the slide groove. A limit pin can be inserted into the top of the slot. An ejector rod is movably embedded inside the slot, and the bottom end of the ejector rod passes through the bottom of the inner wall of the slot and is integrally formed with an ejector block. The outer wall of the ejector block is in contact with the outer wall of the slider.

[0009] As a preferred embodiment of the present invention, the bottom ends of the ejector blocks are all inclined, and the top ends of the sliders are all inclined to cooperate with the bottom ends of the ejector blocks.

[0010] As a preferred technical solution of the present invention, an annular lifting groove is provided on the inner wall surface of the slot, and a number of guide rods are equidistantly arranged around the inner wall of the lifting groove. A collar is sleeved on the surface of the ejector rod, and the collar is sleeved on the surface of each group of guide rods through a through hole. A second spring is wound around the surface of the guide rod, one end of the second spring is connected to the top surface of the collar, and the other end is connected to the top of the inner wall of the lifting groove.

[0011] As a preferred technical solution of the present invention, a threaded groove is provided at the middle of the top of the base, and a rotating rod is engaged inside the top of the threaded groove. A limiting rod is integrally formed on the inner wall of the threaded groove, and the limiting rod passes through the middle of the rotating rod. The top of the rotating rod passes through the middle of the top plate, and the top plate can rotate on the surface of the rotating rod. The heating rod is fitted with a toothed disc at its top end, and the inner wall of the toothed disc has an annular rotating groove. The outer wall of the heating rod is integrally formed with an annular guide rail, and the guide rail and the rotating groove are interlocked. The top end of the toothed disc is provided with a connecting part that meshes with the threaded mounting groove. The rotating rod surface is fitted with toothed rings, and all the toothed rings mesh with the toothed disc for transmission.

[0012] As a preferred embodiment of the present invention, the top and bottom ends of the guide rail are provided with grooves, and the top and bottom ends of the inner wall of the rotating groove are integrally formed with protrusions that fit into the grooves. Several sets of rolling balls are equidistantly embedded on both sides of the inner wall of the groove, and all the balls are in contact with the outer wall of the protrusion.

[0013] As a preferred embodiment of the present invention, the top of the rotating rod is integrally formed with a rotating handle slot, and the top of the rotating handle slot is provided with a hexagonal hole, into which a rotating handle is inserted, and the surface of the rotating handle gripping part is provided with a number of sets of grooves.

[0014] The present invention also provides a technical solution, a method for using an intelligent induction heating device that facilitates the replacement of heating rods, the specific steps of which are as follows: S1. When installing the heating rod 4, move the heating rod 4 and insert it into the heating rod slot 54 for pre-limiting. S2. Push the push block 72 so that the push block 72 pushes the ejector block 75 to rise through the slider 74. The ejector block 75 drives the collar 83 to rise through the ejector rod 77. Under the guidance of the guide rod 82, the collar 83 rises inside the lifting groove 81 and squeezes the second spring 84. The ejector rod 77 can push out the limit pin 62 inserted into the slot 76. S3. Rotate the heating rod slot 54, causing the heating rod slot 54 to drive the rotating shafts 53 on both sides to rotate. As the rotating shafts 53 rotate, the limiting pins 62 move out of the limiting grooves 64. The limiting grooves 64 no longer restrict the position of the rotating shafts 53 in conjunction with the limiting pins 62. The rotating shafts 53 can rotate inside the mounting grooves 52 and drive the heating rod slots 54 to adjust the angle. The heating rod slots 54 drive the heating rods 4 to adjust to a vertical state. S4. Move the rotating handle 11 so that it is inserted into the rotating handle slot 10. Then rotate the rotating handle 11 so that it drives the rotating rod 92 to rotate through the rotating handle slot 10. Under the guidance of the limiting rod 93, the rotating rod 92 moves into the threaded groove 91. The rotating rod 92 drives the top plate 2 to descend. The top plate 2 drives the threaded mounting groove 3 to be fitted onto the surface of the gear plate 95. The gear plate 95 cooperates with the threaded mounting groove 3 to limit the top plate 2. The top plate 2 no longer rotates with the rotating rod 92. At the same time, the rotating rod 92 drives the gear ring 94 to rotate. The gear ring 94 drives multiple gear plates 95 to rotate at the top of the heating rod 4. As the gear plates 95 rotate and the threaded mounting groove 3 descends, the threaded mounting groove 3 and the gear plates 95 can mesh with each other and fix the heating rod 4. The installation of the heating rod 4 is completed. S5. When it is necessary to remove the heating rod 4, simply reverse the operation. The heating rod slot 54 can support the heating rod 4 and prevent it from falling to the ground.

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This device, through its mounting base, mounting slot, and rotating shaft, effectively prevents the heating rod from shattering when the bottom is not supported by hand during disassembly. This is because the mounting slot no longer restrains the heating rod as the threaded component rotates out of the slot, causing it to fall to the ground under gravity. The device ensures the heating rod remains inside the mounting slot after removal. Rotating the mounting slot releases the restraining mechanism on both sides, allowing the heating rod to rotate within the mounting slots. The heating rod then rotates to an inclined position, facilitating removal. When multiple heating rods need replacing, they can be removed simultaneously and then retrieved from the mounting slot later. This facilitates coordinated operations among multiple workers, improving the ease of use and maintenance.

[0016] 2. This device, through its adjustable groove, push block, and sliding groove, effectively prevents the heating rod from accidentally being touched by the operator, causing it to tilt and drive the rotating shaft to continue rotating inside the mounting base. Excessive rotation could cause the heating rod to fall out of the slot. By inserting a limiting pin into the slot, the device locks the rotating shaft in place, preventing the pin from being moved out. To release the limit, the push block is pulled, causing it to push the ejector block upwards via a slider. The ejector block then pushes the ejector rod inside the slot, ejecting the limiting pin. The pin no longer locks the shaft, allowing the heating rod slot to rotate normally, further improving the device's stability during use. Attached Figure Description

[0019] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example: like Figure 1 As shown in Figure 10, this embodiment proposes an intelligent induction heating device that facilitates the replacement of heating rods, including a base 1, a top plate 2, a threaded mounting groove 3, and a heating rod 4. The top plate 2 is provided above the base 1, and the bottom end of the top plate 2 is provided with several sets of threaded mounting grooves 3. The heating rod 4 is installed inside the threaded mounting grooves 3. The top surface of the base 1 is fixedly installed with the same number of mounting seats 51 as the threaded mounting grooves 3, and the top sides of the mounting seats 51 are provided with mounting grooves 52. The two sets of mounting grooves 52 are rotatably provided with rotating shafts 53, and the outer wall surface of the rotating shafts 53 is provided with several sets of limiting mechanisms. The two sets of rotating shafts 53 are connected to the heating rod slots 54, and the bottom ends of the heating rods 4 are engaged inside the heating rod slots 54. The limiting mechanism includes several sets of spring grooves 61 that are equidistantly arranged around the outer wall surface of the rotating shaft 53, and a limiting pin 62 is provided through the outer surface of each spring groove 61. A first spring 63 is provided inside the spring groove 61, and each spring groove 61 is connected to the limiting pin 62 through the first spring 63. The inner wall surface of the mounting base 51 is provided with several sets of limiting grooves 64 at equal intervals, and each limiting groove 64 has a limiting pin 62 inserted into its inner wall. The outer end of each limiting pin 62 is arc-shaped, and each limiting groove 64 is an arc-shaped groove that cooperates with the limiting pin 62. Through this design, when the outer end of the limiting pin 62 is subjected to an external force with a specific arc angle, the limiting pin 62 can be displaced and moved out of the limiting groove 64, thereby achieving the purpose of releasing the limitation of the limiting pin 62 and the limiting groove 64 on the position of the rotating shaft 53. When the heating rod 4 needs to be disassembled, rotating the heating rod slot 54 causes the rotating shafts 53 on both sides to rotate. The rotating shafts 53 drive the limiting pins 62 to rotate via the spring grooves 61 and press against the inner wall of the limiting grooves 64. Under the reaction force of the inner wall of the limiting grooves 64, the limiting pins 62 move into the spring grooves 61 and press against the first spring 63. The first spring 63 undergoes elastic deformation due to the pressure of the limiting pins 62, allowing the limiting pins 62 to retract into the spring grooves 61 and move out of the limiting grooves 64. The limiting grooves 64 no longer restrict the position of the rotating shaft 53 with the limiting pins 62, and the rotating shaft 53 can rotate under the restriction of the mounting grooves 52 on both sides. The heating rod 4 can rotate together with the heating rod slot 54. When tilted, it is easy for staff to remove the device. After being rotated to a certain angle, the elastic deformation of the first spring 63 restores the position of the limiting pin 62, which pops out from the spring groove 61 and inserts into another limiting groove 64. The limiting pin 62, together with the other limiting groove 64, restricts the position of the rotating shaft 53. Without external force, the heating rod slot 54 cannot continue to drive the rotating shaft 53 to rotate. When multiple heating rods 4 need to be replaced, staff can rotate and remove multiple heating rods 4 at once, and then remove the heating rods 4 from the heating rod slot 54. This facilitates the cooperation of multiple staff to carry out assembly line operations and improves the convenience of using and maintaining the device.

[0021] The mounting base 51 is provided with a release mechanism, which includes an adjustment groove 71 opened in the middle of the top of the mounting base 51, and a push block 72 is movably embedded in the adjustment groove 71. Both sides of the adjustment groove 71 are provided with sliding grooves 73, and sliders 74 are slidably arranged in the sliding grooves 73. Both sets of sliders 74 pass through the sliding grooves 73 and are connected to the push block 72. The bottom of the inner wall of the mounting base 51 is provided with a slot 76, which passes through the mounting base 51 and the slide groove 73. The top of the slot 76 can be inserted with a limiting pin 62. The ejector rod 77 is movably embedded in the slot 76, and the bottom of the ejector rod 77 passes through the bottom of the inner wall of the slot 76 and is integrally formed with an ejector block 75. The outer wall of the ejector block 75 is in contact with the outer wall of the slider 74. The bottom of the ejector block 75 is inclined. The top of the slider 74 is inclined to cooperate with the bottom of the ejector block 75. Through this design, when the push block 72 drives the slider 74 to move inside the slide groove 73, it can be in contact with the bottom of the ejector block 75. Under the continuous movement of the slider 74, the ejector block 75 is pushed up, thereby achieving the purpose of adjusting the position of the ejector rod 77 through the ejector block 75. After the heating rod slot 54 drives the rotating shaft 53 to rotate inside the mounting slot 52, the lowest limiting pin 62 can be inserted into the slot 76. Since the slot 76 is not an arc-shaped slot that cooperates with the limiting pin 62, the limiting between the slot 76 and the limiting pin 62 cannot be released by rotating the rotating shaft 53. The rotating shaft 53 cannot continue to rotate, thereby achieving the purpose of locking the position of the rotating shaft 53. When it is necessary to release the restriction of the limiting pin 62 and the slot 76 on the rotating shaft 53, by pulling the push block 72, the push block 72 drives the sliders 74 on both sides to move inside the slide groove 73 under the restriction of the adjustment groove 71. As the sliders 74 move, the sliders 74 contact the ejector block 75 and push the ejector block 75 to rise. The ejector block 75 drives the ejector rod 77 to move inside the slot 76 and push out the limiting pin 62 inserted inside the slot 76. The lower limiting pin 62 cannot be inserted into the slot 76 to lock the rotating shaft 53, and the heating rod slot 54 can drive the rotating shaft 53 to rotate normally inside the mounting groove 52.

[0022] To enable the ejector rod 77 to move and reset itself within the slot 76, an annular lifting groove 81 is provided on the inner wall surface of the slot 76, and several sets of guide rods 82 are equidistantly arranged around the inner wall of the lifting groove 81. A collar 83 is fitted onto the surface of the ejector rod 77, and the collar 83 is fitted onto the surface of each set of guide rods 82 through through holes in its surface. A second spring 84 is wound around the surface of the guide rod 82. One end of the second spring 84 is connected to the top surface of the collar 83, and the other end is connected to the top of the inner wall of the lifting groove 81. With this design, after the slider 74 is removed from below the ejector block 75, the ejector rod 77 no longer squeezes the second spring 84 through the collar 83. The second spring 84 recovers its elastic deformation and pushes the collar 83 to move within the lifting groove 81. The collar 83 resets under the guidance of the guide rods 82, allowing the ejector rod 77 to reset. The limiting pin 62 can then be reinserted into the slot 76 to lock the rotating shaft 53. In order to connect multiple heating rods 4 to the threaded mounting groove 3 at the same time, a threaded groove 91 is provided at the middle of the top of the base 1, and a rotating rod 92 is engaged inside the top of the threaded groove 91. A limiting rod 93 is integrally formed on the inner wall of the threaded groove 91, and the limiting rod 93 passes through the middle of the rotating rod 92. The top of the rotating rod 92 passes through the middle of the top plate 2, and the top plate 2 can rotate on the surface of the rotating rod 92. A toothed disc 95 is fitted onto the top of the heating rod 4, and an annular rotating groove 96 is formed on the inner wall of the toothed disc 95. An annular guide rail 97 is integrally formed on the outer wall of the heating rod 4, and the guide rail 97 and the rotating groove 96 are interlocked. Grooves are formed at both the top and bottom of the guide rail 97. Protrusions that interlock with the grooves are integrally formed at both the top and bottom of the inner wall of the rotating groove 96. Several sets of rolling balls 98 are equidistantly embedded on both sides of the inner wall of the groove, and the balls 98 are all in contact with the outer wall of the protrusions. Through this design, the toothed disc 95 drives the heating rod 4. When the rotating groove 96 rotates on the surface of the guide rail 97, the groove and the protrusion can cooperate to restrict the position of the gear disk 95. When the rotating groove 96 rotates, it can push the ball 98 to roll, thereby reducing the contact area between the guide rail 97 and the rotating groove 96, and reducing the friction force when the gear disk 95 drives the rotating groove 96 to rotate. The top of the gear disk 95 is provided with a connecting part that meshes with the threaded mounting groove 3. The rotating rod 92 is fitted with a toothed ring 94, and all the toothed rings 94 mesh with the gear disk 95 for transmission. When the heating rod 4 needs to be installed, the rotating rod 92 is rotated, and under the guidance of the limiting rod 93, the rotating rod 92 moves into the threaded groove 91. When the rotating rod 92 drives the top plate 2 to a certain height, the toothed disc 95 installed on the top of the heating rod 4 can drive the connecting part set on its top to be inserted into the threaded mounting groove 3. During the rotation of the rotating rod 92, the toothed disc 95 is driven to rotate through the toothed ring 94, so that the toothed disc 95 drives the rotating groove 96 to rotate under the restriction of the guide rail 97. As the toothed disc 95 rotates and the threaded mounting groove 3 descends, the toothed disc 95 can engage into the threaded mounting groove 3 and restrict the position of the heating rod 4. The installation of the heating rod 4 is completed.

[0023] To facilitate the rotation of the rotating rod 92, a handle slot 10 is integrally formed at the top of the rotating rod 92, and a hexagonal hole is opened at the top of the handle slot 10. The handle 11 is inserted into the hexagonal hole, and several sets of grooves are arranged on the surface of the grip part of the handle 11. With this design, the operator can insert the handle 11 into the handle slot 10 to connect with the rotating rod 92. By rotating the handle 11, the rotating rod 92 is rotated. When rotating the handle 11, the fingers can sink into the grooves on the surface of the handle 11, increasing the contact area between the fingers and the handle 11, thereby increasing the friction generated when rotating the handle 11 and preventing slippage.

[0024] A method for using an intelligent induction heating device that facilitates the replacement of heating rods, the specific steps of which are as follows: S1. When installing the heating rod 4, move the heating rod 4 and insert it into the heating rod slot 54 for pre-limiting. S2. Push the push block 72 so that the push block 72 pushes the ejector block 75 to rise through the slider 74. The ejector block 75 drives the collar 83 to rise through the ejector rod 77. Under the guidance of the guide rod 82, the collar 83 rises inside the lifting groove 81 and squeezes the second spring 84. The ejector rod 77 can push out the limit pin 62 inserted into the slot 76. S3. Rotate the heating rod slot 54, causing the heating rod slot 54 to drive the rotating shafts 53 on both sides to rotate. As the rotating shafts 53 rotate, the limiting pins 62 move out of the limiting grooves 64. The limiting grooves 64 no longer restrict the position of the rotating shafts 53 in conjunction with the limiting pins 62. The rotating shafts 53 can rotate inside the mounting grooves 52 and drive the heating rod slots 54 to adjust the angle. The heating rod slots 54 drive the heating rods 4 to adjust to a vertical state. S4. Move the rotating handle 11 so that it is inserted into the rotating handle slot 10. Then rotate the rotating handle 11 so that it drives the rotating rod 92 to rotate through the rotating handle slot 10. Under the guidance of the limiting rod 93, the rotating rod 92 moves into the threaded groove 91. The rotating rod 92 drives the top plate 2 to descend. The top plate 2 drives the threaded mounting groove 3 to be fitted onto the surface of the gear plate 95. The gear plate 95 cooperates with the threaded mounting groove 3 to limit the top plate 2. The top plate 2 no longer rotates with the rotating rod 92. At the same time, the rotating rod 92 drives the gear ring 94 to rotate. The gear ring 94 drives multiple gear plates 95 to rotate at the top of the heating rod 4. As the gear plates 95 rotate and the threaded mounting groove 3 descends, the threaded mounting groove 3 and the gear plates 95 can mesh with each other and fix the heating rod 4. The installation of the heating rod 4 is completed. S5. When it is necessary to remove the heating rod 4, simply reverse the operation. The heating rod slot 54 can support the heating rod 4 and prevent it from falling to the ground.
