Description

Technical Field

[0001] The present invention relates to a magnetic concentrating heating component and a heating device, in particular to a column-shaped magnetic core, a heating source, a heating head and a heater. Background Art

[0002] Heating and welding are common processing methods in industry and production, such as the plastics and rubber industry, transportation applications such as tunnel engineering, plastic film blowing machines, wire drawing machines, and injection molding machines, as well as the pharmaceutical, energy, and food industries. Electromagnetic heating has been a popular heating method for many years. Conventional heating coils typically use contact heat transfer, resulting in low thermal efficiency, with only 30%-70% of their energy consumption converted into working heat. Furthermore, due to the cooling inertia associated with heating, delayed heating can extend the heating time due to heat dissipation. Electromagnetic induction heating, on the other hand, utilizes non-contact electromagnetic induction heating, applying heat directly to the workpiece, eliminating heat losses from heat transfer and resulting in rapid and efficient heating.

[0003] On February 17, 2014, the applicant filed an invention patent application entitled "A Handheld Electromagnetic Heater" with the Patent Office of the State Intellectual Property Office of the People's Republic of China and was granted the invention patent right with patent number 201410053724.2.

[0004] Because this patented product uses electromagnetic heating technology, the heating efficiency and quality are greatly improved, so it is very popular with customers. However, during the production and use process over the past few years, some new technical problems have also been discovered.

[0005] First, the front end of the heating source is not easy to approach the hot melt sheet (the hot melt sheet is equipped with a metal, such as an iron mesh, an iron nail, etc.), which cannot further improve the heating efficiency.

[0006] Second, the electromagnetic heating coil is easy to burn out, affecting the normal progress of welding work.

[0007] Third, bipolar transistors (IGBTs) are very easy to burn out. After repeated analysis, testing, and research, the cause of burning out of bipolar transistors (IGBTs) has not been found.

[0008] Fourth, although the handheld electromagnetic heater is equipped with a variety of heating heads with different front panels, it was found during use that the hot melt piece was severely deformed after being nailed to the wall, and the conditions were different. It is far from enough to rely solely on the existing heating heads with different front panels. Even if the number of heating heads with different front panels is doubled, it cannot meet the needs of the work. Moreover, frequent replacement of heating heads will not only increase the labor intensity of the operator, but also affect work efficiency and cannot achieve the best effect.

[0009] Fifth, because the rear of the heating head has a straight groove that matches the front of the cavity, a corresponding straight groove is formed, forming a plug-and-clip fixed structure similar to a snap-on bottle mouth and bottle cap with a clamping head and a clamping mouth. During operation, it was found that the connection of this plug-and-clip fixed structure is weak. Due to the heavy heating head, it is easy to fall off the gun body, and in serious cases, the heating head will be damaged. To prevent the heating head from falling off, the operator has to hold the electromagnetic heater with both hands or hold the heating head upward, which is not very convenient to use.

[0010] Sixth, most waterproof cloths are not transparent. During the heating and welding process, it is difficult to find the correct position of the hot melt piece, which can easily cause welding leaks, false welding, and biased welding.

[0011] Seventh, the resonant capacitor is installed in the main chassis, and the voltage between the induction coil and the resonant capacitor can reach 1000 V to 1800 V. When working, the operating line of about 16 meters is in the humid and harsh tunnel working environment, which is extremely dangerous. Summary of the Invention

[0013] The second technical problem to be solved by the present invention is to provide a heating source, which can be used in a heating head to further improve the magnetic concentration effect, further increase the effective heating distance, and further improve the heating efficiency.

[0014] The third technical problem to be solved by the present invention is to provide a heating head, which can be used in a heater to further improve the magnetic concentration effect, further increase the effective heating distance, and further improve the heating efficiency.

[0015] The fourth technical problem to be solved by the present invention is to provide a heater that can effectively dissipate heat, further improve the magnetic field concentration effect, further increase the effective heating distance, and further improve the heating efficiency.

[0016] Regarding the first magnetic concentrating heating component, to address the first technical problem described above, the present invention provides a cylindrical can-shaped magnetic core comprising a concentrically arranged magnetic core post, a magnetic core base, and a magnetic core wall. The magnetic core post, the magnetic core base, and the magnetic core wall form a single piece. The magnetic core post is a fixed magnetic core post, and its height is greater than that of the magnetic core wall. Alternatively, the magnetic core base and the magnetic core wall form a single piece, the magnetic core post and the magnetic core base are separate, and the magnetic core post is a movable magnetic core post.

[0017] The difference between the height of the magnetic core column and the height of the magnetic core wall is 7 mm to 44 mm, 15 mm, 20 mm, or 25 mm.

[0018] The shape of the magnetic core column is cylindrical. The shape of the head and / or tail of the magnetic core column is plane, spherical or parabolic.

[0019] The shape of the magnetic core bottom is disc-shaped. A guide hole is provided in the center of the magnetic core bottom.

[0020] The root of the movable magnetic core column is located in the guide hole. The bottom of the magnetic core is located at the rear end of the guide hole and is provided with an insulating elastic component made of rubber material.

The magnetic core column, the magnetic core bottom, and the magnetic core wall form an integral part. The magnetic core column is a fixed magnetic core column, and the height of the magnetic core column is greater than the height of the magnetic core wall (which facilitates the head of the magnetic core column to approach the hot melt, further increasing the effective heating distance and improving heating efficiency). Alternatively, the magnetic core bottom and the magnetic core wall form an integral part, and the magnetic core column and the magnetic core bottom are separated (which facilitates the head of the magnetic core column to approach the hot melt, further increasing the effective heating distance and improving heating efficiency). The magnetic core column is a technical means of a movable magnetic core column. Therefore, a variety of heating sources can be produced according to actual conditions and the needs of different customers.

[0025] 2. Since the present technical solution adopts the technical means that the shape of the magnetic core column is cylindrical; the shape of the head and / or tail of the magnetic core column is planar, spherical or parabolic, it is more conducive to the head of the magnetic core column being close to the hot melt plate, thereby further improving the heating efficiency.

[0027] 4. This technical solution adopts the technical means that the bottom of the magnetic core is provided with an insulating elastic component at the rear end of the guide hole; the insulating elastic component is made of rubber material, so it is beneficial to apply balanced pressure to the waterproof plate through the movable magnetic core column.

This technical solution adopts the following technical means: the magnetic core column is provided with a vent at the axial position; the bottom of the magnetic core and the two sides opposite to each other are provided with notches; the notches are opposite to the heat dissipation gap of the electromagnetic heating coil; the shape of the notch is fan-shaped when viewed from the axial direction; the two radial sides of the notch are perpendicular to each other; and the bottom sides of the two notches are parallel to each other, so it is beneficial to the heat dissipation of the heating source.

[0029] 6. This technical solution is beneficial for positioning the heating source because it adopts the technical means of providing positioning grooves along the axial direction on the two opposite outer side surfaces of the magnetic core wall.

[0030] As for the second magnetic field heating component, in order to solve the second technical problem mentioned above, the present invention provides a heating source, including a magnetic core, and the magnetic core is the cylindrical can-shaped magnetic core mentioned above.

[0031] The magnetic core column is inserted into the electromagnetic heating coil.

[0032] The electromagnetic heating coil is provided with a heat dissipation gap.

[0033] The heat dissipation gap includes an axial heat dissipation gap between layers in the electromagnetic heating coil and / or a radial heat dissipation gap between turns in the electromagnetic heating coil.

[0034] The heat dissipation gap is arranged on two opposite sides of the electromagnetic heating coil. The shape of the electromagnetic heating coil gradually changes from a circle to an ellipse from the inner layer to the outer layer.

[0035] The electromagnetic heating coil is fixed at both ends of the elliptical minor axis by binding components, which are thin wires or insulating tapes.

[0036] There are two types of heat dissipation gap processes. One involves removing the isolation component after the electromagnetic heating coil is wound and cured with glue, leaving a heat dissipation gap. The other process retains the isolation component. In the process retaining the isolation component, a coil heat dissipation isolation component is placed between the heat dissipation gaps. The coil heat dissipation isolation component can be cylindrical, tubular, comb-shaped, or nylon plastic screw bracket-shaped. The cross-section of the cylindrical coil heat dissipation isolation component is circular, semicircular, elliptical, or semi-elliptical.

Therefore, the heating source is used in the heating head to facilitate the head of the magnetic core column to be close to the hot melt sheet, thereby improving the heating efficiency.

[0043] 2. This technical solution utilizes a heat dissipation gap in the electromagnetic heating coil. Therefore, the electromagnetic heating coil can effectively dissipate heat when used in the heating source, effectively preventing burnout and short circuits caused by the high temperature of the electromagnetic heating coil during operation. It also effectively reduces magnetic saturation, preventing burnout of bipolar transistors (IGBTs) due to magnetic saturation (a beneficial effect unexpectedly discovered by the applicant), ensuring the normal operation of welding operations.

[0044] 3. This technical solution adopts the technical means that the heat dissipation gap includes the axial heat dissipation gap between the layers of the electromagnetic heating coil and / or the radial heat dissipation gap between the turns of the electromagnetic heating coil, so it can achieve maximum heat dissipation.

This technical solution adopts the technical means of setting the heat dissipation gap on the two opposite sides of the electromagnetic heating coil; and gradually changing the shape of the electromagnetic heating coil from the inner layer to the outer layer from circular to elliptical, thus creating favorable conditions for the subsequent improvement of the magnetic core.

[0046] 5. This technical solution fixes the electromagnetic heating coil at both ends of the elliptical short axis by binding components; the binding components are technical means of thin wires or insulating tapes, so the electromagnetic heating coil can be prevented from falling off.

[0047] 6.

[0177] like Figures 17 and 18 As shown, this embodiment provides a column-shaped magnetic core 1-3-4, the column-shaped magnetic core 1-3-4 includes a concentrically arranged magnetic core column 1-3-4-1, a magnetic core bottom 1-3-4-2, and a magnetic core wall 1-3-4-3, the magnetic core column 1-3-4-1, the magnetic core bottom 1-3-4-2, and the magnetic core wall 1-3-4-3 form an integral part, the magnetic core column 1-3-4-1 is a fixed magnetic core column 1-3-4-1, and the height of the magnetic core column 1-3-4-1 is greater than or equal to the height of the magnetic core wall 1-3-4-3. Of course, it can also be as follows Figure 19 As shown, the core bottom 1-3-4-2 and the core wall 1-3-4-3 form an integral part, the core column 1-3-4-1 and the core bottom 1-3-4-2 are separate, and the core column 1-3-4-1 is a movable core column 1-3-4-1.

[0178] Various modifications of this embodiment will be described below.

[0179] The difference between the height of the magnetic core column 1-3-4-1 and the height of the magnetic core wall 1-3-4-3 is 7MM to 44MM.

[0180] The difference between the height of the magnetic core column 1-3-4-1 and the height of the magnetic core wall 1-3-4-3 is 15MM, 20MM, and 25MM.

[0183] The core bottom 1-3-4-2 is in the shape of a disk.

[0184] A guide hole or ventilation hole is provided in the center of the core bottom 1-3-4-2.

[0185] The root of the movable magnetic core column 1-3-4-1 is located in the guide hole.

[0186] The magnetic core column 1-3-4-1 is provided with an insulating elastic component 1-3-4-7.

[0187] The insulating elastic components 1-3-4-7 are made of elastic rubber material.

[0188] The elastic adhesive material is a rubber material or a silicone material.

[0189] like Figure 19 As shown, the insulating elastic component 1-3-4-7 is made of a long strip of rubber or silicone material, with both ends glued to the bottom of both sides of the back of the magnetic core bottom 1-3-4-2, and the middle is firmly attached to the movable magnetic core, like a bow and arrow.

[0190] like Figure 3a As shown, the insulating elastic component 1-3-4-7 can be a small pneumatic plastic telescopic rod, which includes a sleeved cylinder, an elastic body is arranged in the cylinder, and the elastic body is a spring or an elastic air bag. The small pneumatic plastic telescopic rod is like a hollow syringe, supported on the movable magnetic core column 1-3-4-1 and the reinforcement rib 1-1-4-5 at the bottom of the shell.

[0191] The movable magnetic core column 1-3-4-1 is pressed by the workpiece during operation and is forced to move backward, and vice versa, moves forward, and is reset under the action of the insulating elastic component 1-3-4-7 at the bottom.

[0192] The shape of the magnetic core column 1-3-4-1 is cylindrical.

[0193] The core bottom 1-3-4-2 is in the shape of a disk.

[0194] The core wall 1-3-4-3 is cylindrical in shape.

[0195] The magnetic core column 1-3-4-1 is provided with a ventilation opening 1-3-4-4 at the axial position.

[0196] Notches 1-3-4-5 are respectively provided on opposite sides of the core bottom 1-3-4-2 and the core wall 1-3-4-3.

[0197] The notch 1-3-4-5 is opposite to the heat dissipation gap of the electromagnetic heating coil 1-3-1.

[0198] Viewed from the axial direction, the shape of the notches 1-3-4-5 is fan-shaped.

[0199] The two radial sides of the notch 1-3-4-5 are perpendicular to each other.

[0200] The bottom sides of the two notches 1-3-4-5 are parallel to each other.

[0201] Two opposite outer side surfaces of the core wall 1-3-4-3 are respectively provided with positioning grooves 1-3-4-6 along the axial direction.

[0202] The electromagnetic heating coil 1-3-1 is sleeved on the magnetic core column 1-3-4-1.

[0203] The coil baffle 1-3-3-2 is located at the root of the magnetic core column 1-3-4-1.

[0204] like Figure 13 and Figures 17 to 19 As shown, this embodiment provides a heating source 1-3, and the heating source 1-3 includes a magnetic core 1-3-4, and the magnetic core 1-3-4 is the can-shaped magnetic core 1-3-4 mentioned above.

[0205] Various modifications of this embodiment will be described below.

[0206] like Figure 13 and Figures 17 to 19 As shown, the magnetic core column 1-3-4-1 of the tank-shaped magnetic core 1-3-4 is inserted into the electromagnetic heating coil 1-3-1.

[0207] like Figures 13 and 14 As shown,

[0208] The electromagnetic heating coil 1-3-1 is provided with a heat dissipation gap.

[0209] This embodiment effectively dissipates heat, effectively preventing the electromagnetic heating coil from burning out due to the high temperature during operation, causing open circuits or short circuits. It also effectively reduces magnetic saturation, preventing the burnout of the bipolar transistor (IGBT) due to magnetic saturation. This helps protect the bipolar transistor (IGBT) in the power supply and ensures normal welding operation.

[0210] like Figures 13 and 14 As shown, the heat dissipation gap includes the axial heat dissipation gap between the layers of the electromagnetic heating coil 1-3-1. Of course, it is also possible that the heat dissipation gap includes the radial heat dissipation gap between the turns of the electromagnetic heating coil 1-3-1.

[0211] The heat dissipation gap is arranged on two opposite sides of the electromagnetic heating coil 1-3-1.

[0212] The shape of the electromagnetic heating coil 1 - 3 - 1 gradually changes from a circular shape to an elliptical shape from the inner layer to the outer layer.

[0213] The electromagnetic heating coil 1-3-1 is fixed at both ends of the elliptical short axis by binding components 1-3-5.

[0214] The binding components 1-3-5 are thin wires or insulating tapes.

[0215] A coil heat dissipation isolation component 1-3-2 is provided between the heat dissipation gaps.

[0216] The coil heat dissipation isolation component 1-3-2 is in the shape of a column. Of course, the coil heat dissipation isolation component 1-3-2 can also be in the shape of a tube, a comb, or a screw support.

[0218] The cross-section of the tubular coil heat dissipation isolation component 1-3-2 is in the shape of a circular ring.

[0219] The comb body of the comb-toothed coil heat dissipation isolation component 1-3-2 is in the shape of an elongated strip, and the length of the comb body corresponds to the axial length of the electromagnetic heating coil 1-3-1. The comb tooth length of the comb-toothed coil heat dissipation isolation component 1-3-2 is less than or equal to the radial thickness of the electromagnetic heating coil 1-3-1.

[0220] The shape of the screw bracket-shaped coil heat dissipation isolation component 1-3-2 is a prismatic bracket body.

[0221] The prism support body is a prism support body formed by fixed connection with a screw rod.

[0222] The prism support body is a triangular prism support body, a quadrangular prism support body or a hexagonal prism support body.

[0223] The lead screw is a rod made of rigid wire (such as nylon plastic).

[0224] The coil heat dissipation isolation component 1-3-2 is made of insulating material.

[0225] The insulating material is wood, bamboo, nylon, epoxy material, bakelite or polytetrafluoroethylene.

[0226] The electromagnetic heating coil 1-3-1 is shaped by shaping glue.

[0227] The shaping glue is a water-like shaping glue or a paste-like shaping glue.

[0228] The water-like shaping glue is 502 glue or 508 glue or 488 glue or 108 glue or ring-speed slow concentrated glue or 101 glue or 201 glue or 301 glue or 401 glue or 260 glue.

[0230] like Figures 13 to 16 As shown, the electromagnetic heating coil 1-3-1 is wound on the coil frame 1-3-3.

[0231] The coil skeleton 1-3-3 is made of PBT.

[0232] The coil skeleton 1-3-3 is made of heat-resistant materials such as polytetrafluoroethylene, nylon, epoxy material, or bakelite.

[0233] The coil skeleton 1-3-3 includes a skeleton body 1-3-3-1 and a coil baffle 1-3-3-2.

[0234] The skeleton body 1-3-3-1 is cylindrical in shape.

[0235] There is one coil baffle 1-3-3-2. Of course, there can also be two coil baffles 1-3-3-2.

[0236] A coil baffle 1-3-3-2 is arranged at the rear end of the skeleton body 1-3-3-1.

[0237] One of the coil baffles 1-3-3-2 is in the shape of a circular ring.

[0238] Two opposite sides of the annular coil baffle 1-3-3-2 are respectively provided with notches 1-3-3-3.

[0239] The shape of the notch 1-3-3-3 is fan-shaped.

[0240] The two radial sides of the fan-shaped notch 1-3-3-3 are perpendicular to each other.

[0241] The bottom sides of the two fan-shaped notches 1-3-3-3 are parallel to each other.

[0242] The notch 1-3-3-3 is opposite to the heat dissipation gap of the electromagnetic heating coil 1-3-1.

[0243] The two coil baffles 1-3-3-2 are arranged at the front end and the rear end of the skeleton body 1-3-3-1.

[0244] The two coil baffles have the same shape.

[0245] There are two types of heat dissipation gap processes. One involves removing the isolation component after the electromagnetic heating coil is wound and cured with glue, leaving a heat dissipation gap. The other process retains the isolation component. In this process, a coil heat dissipation isolation component is placed between the heat dissipation gaps.
