Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and in particular to a uniform heating device for potting compound production. Background Technology

[0002] Potting is the process of mechanically or manually injecting a liquid polyurethane compound into devices containing electronic components or circuitry, which then cures at room temperature or under heating conditions to become a high-performance thermosetting polymer insulating material. The liquid polyurethane compound used in this process is called potting compound. Potting compounds are used for bonding, sealing, potting, and coating protection of electronic components. Before curing, potting compound is liquid and has fluidity; its viscosity varies depending on the material, performance, and manufacturing process of the product. Potting compound only realizes its value after complete curing. After curing, it provides waterproofing, moisture resistance, dustproofing, insulation, thermal conductivity, security, corrosion resistance, temperature resistance, and shock absorption. At room temperature, potting compound is too viscous; heating increases its fluidity, making it easier to mix and pour, and it is particularly suitable for filling the small gaps in precision electronic components.

[0003] Utility model CN211462904U discloses a stirring device for the production of electronic potting adhesives, relating to the field of electronic component technology. It includes a workbench, a cylinder, and a stirring mechanism. The cylinder is fixedly mounted on the workbench, with a feeding hopper above it and a feeding solenoid valve on the feeding pipe. A gravity sensor is located at the bottom of the feeding hopper. The stirring device is housed within the cylinder and includes a stirring motor, a lifting auger, a sleeve, and stirring rollers. The stirring motor is located at the bottom of the workbench and is connected to the lifting auger. The lifting auger is vertically positioned, with its top end connected to a bearing seat at the top of the cylinder. The sleeve is fixedly connected to the lifting auger, and stirring rollers are symmetrically arranged outside the sleeve, each containing a built-in heating core. This utility model features a simple structure and convenient use. The feeding hopper provides quantitative feeding, and the stirring mechanism also lifts the adhesive during stirring, ensuring thorough flow of the adhesive within the cylinder, more uniform heating, and more efficient stirring.

[0004] After searching, it was found that the existing technology has certain defects. Because the sleeve and the lifting auger are connected, the sleeve and the lifting auger rotate in the same direction and at the same speed, resulting in poor lifting and mixing effect and low overall uniform heating efficiency of the potting compound. Therefore, a uniform heating device for potting compound production is needed to meet people's needs. Summary of the Invention

[0005] The purpose of this invention is to provide a uniform heating device for potting compound production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a uniform heating device for producing potting compound, comprising a tank, a heating element disposed at the bottom of the tank, a support disposed at the top of the tank, a motor disposed on the support, a first helical gear disposed at the output end of the motor, a rotating shaft connected to the bottom of the first helical gear, the rotating shaft being rotatably connected to the tank, a first auger disposed on the outer wall of the rotating shaft, a driven helical gear rotatably connected to one side of the support, the driven helical gear meshing with the first helical gear, a second helical gear meshing below the driven helical gear, a sleeve connected to the bottom of the second helical gear, a sleeve sleeved to the bottom of the sleeve, the sleeve sleeved to the outside of the first auger, the top of the sleeve being closed and the bottom being open, and several slots being formed on the outer wall near the top.

[0007] Preferably, the tank body has a feed inlet at the top and a discharge outlet on the bottom outer wall, and the discharge outlet is equipped with a solenoid valve.

[0008] Preferably, the tank is equipped with a spiral heating tube, which is connected to a hot oil circulation system.

[0009] Preferably, the bracket is U-shaped, with its open end connected to the top of the tank. A positioning shaft is provided on one side of the bracket, and the center of the driven helical gear is rotatably connected to the outer wall of the positioning shaft.

[0010] Preferably, the rotating shaft is rotatably connected inside the top end of the second helical gear, sleeve, and bushing.

[0011] Preferably, a second spiral auger is provided on the outer wall of the sleeve below the slot, and the spiral direction of the second spiral auger is the same as that of the first spiral auger.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the meshing relationship between the driven helical gear and the first and second helical gears enables the motor to drive the first helical gear, the shaft, and the first auger to rotate clockwise, while the second helical gear drives the sleeve and the bushing to rotate counterclockwise. This creates a rotational effect in different directions between the bushing and the first auger, thereby lifting the potting compound heated at the bottom from the bottom up. This allows the compound to mix with the unheated potting compound at the top, creating a continuous cycle that improves the efficiency of uniform mixing and heating of the potting compound.

[0014] In this invention, the spiral heating tube enables the potting compound inside the tank near the outside to be heated. Through the circulation effect inside and outside and top and bottom, the efficiency of uniform heating is further improved. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A uniform heating device for producing potting compound includes a tank 1, a heating element 2 disposed at the bottom of the tank 1, a support 3 disposed at the top of the tank 1, a motor 4 disposed on the support 3, a first helical gear 5 disposed at the output end of the motor 4, a rotating shaft 6 connected to the bottom end of the first helical gear 5, the rotating shaft 6 being rotatably connected inside the tank 1, a first auger 7 disposed on the outer wall of the rotating shaft 6, a driven helical gear 8 rotatably connected to one side of the support 3, the driven helical gear 8 meshing with the first helical gear 5, a second helical gear 9 meshing below the driven helical gear 8, a sleeve 10 connected to the bottom end of the second helical gear 9, a sleeve 11 connected to the bottom end of the sleeve 10, the sleeve 11 being sleeved on the outside of the first auger 7, the top end of the sleeve 11 being closed and the bottom end being open, and a plurality of slots 12 being formed on the outer wall near the top end.

[0024] Through the meshing relationship between the driven helical gear 8, the first helical gear 5, and the second helical gear 9, the motor 4 drives the first helical gear 5, the rotating shaft 6, and the first auger 7 to rotate clockwise. At the same time, the second helical gear 9 drives the sleeve 10 and the sleeve 11 to rotate counterclockwise. This creates a rotational effect between the sleeve 11 and the first auger 7 in different directions, thereby lifting the potting compound that has been heated by the heating element 2 at the bottom from bottom to top. The lifted hot potting compound flows out from the slot 12 and mixes with the unheated potting compound at the top. This cycle repeats, improving the efficiency of uniform mixing and heating of the potting compound.

[0025] Specifically, in this embodiment, a feed inlet is provided at the top of the tank 1, and a discharge outlet is provided on the outer wall at the bottom. The discharge outlet is equipped with a solenoid valve. The feed inlet is used to pour the viscous potting compound at room temperature into the tank 1 for uniform heating, and the discharge outlet is used to discharge the heated potting compound with reduced viscosity from the tank 1. The solenoid valve prevents the potting compound from leaking out during the uniform heating process.

[0026] Specifically, in this embodiment, a spiral heating tube 13 is provided inside the tank 1. The spiral heating tube 13 is connected to the hot oil circulation system. The temperature of the hot oil inside the spiral heating tube 13 is consistent with the heating temperature of the heating element 2. By setting the spiral heating tube 13, the potting compound inside the tank 1 near the outside is heated. Through the circulation effect inside and outside and up and down, the efficiency of uniform heating is further improved.

[0027] Specifically, in this embodiment, the bracket 3 is U-shaped, with its open end connected to the top of the tank 1. A positioning shaft 14 is provided on one side inside the bracket 3. The center of the driven helical gear 8 is rotatably connected to the outer wall of the positioning shaft 14. The positioning shaft 14 provides a stable fulcrum for the rotation of the driven helical gear 8.

[0028] Specifically, in this embodiment, the rotating shaft 6 is rotatably connected inside the top end of the second helical gear 9, the sleeve 10 and the sleeve 11, and the rotating shaft 6 and the second helical gear 9, the sleeve 10 and the sleeve 11 have the same rotational positioning effect.

[0029] Specifically, in this embodiment, a second spiral auger 15 is provided on the outer wall of the sleeve 11 below the slot 12. The spiral direction of the second spiral auger 15 is the same as that of the first spiral auger 7. The clockwise rotation of the first spiral auger 7 realizes the lifting effect of the hot potting compound inside the sleeve 11. The counterclockwise rotation of the sleeve 11 by the second spiral auger 15 realizes the top-to-bottom conveying effect of the potting compound outside the sleeve 11, thereby improving the circulation effect of the potting compound between the inside and outside of the sleeve 11, and thus improving the uniform mixing and heating efficiency.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
