Description

Technical Field

[0001] This utility model relates to the field of epoxy resin production technology, specifically to a vacuum nitrogen sealing mixing equipment for bisphenol A phenolic special epoxy resin. Background Technology

[0002] Epoxy resin is a polymer compound containing two or more epoxy groups. Epoxy resin possesses excellent insulation, corrosion resistance, chemical resistance, heat resistance, and adhesion, and is widely used in insulation and encapsulation of electronic and electrical products, coatings, composite materials, building materials, and adhesives. This research aims to develop a new type of green and environmentally friendly bisphenol A phenolic resin for electronic base materials, used to prepare copper-clad laminates with high heat resistance, low expansion rate, and high glass transition temperature suitable for lead-free processes. This will meet the market's high-quality requirements for electronic base materials—copper-clad laminates—and reduce their production costs. In resin production, various raw materials need to be prepared in proportion before mixing. Traditional mixing methods often involve manual feeding, which is inefficient. To improve this, a vacuum nitrogen-sealing mixing device for bisphenol A phenolic resin is proposed.

[0003] As disclosed in the authorization announcement number CN222534780U, a modified epoxy resin mixing device includes a machine body. Both sides of the top of the machine body are provided with feed inlets. A metering mechanism is fixedly provided at the top of the feed inlet. A rotating block is movably arranged inside the machine body through a rotating shaft. A drive motor is mounted on one end of the rotating block's rotating shaft at the top of the machine body through a mounting base. The output shaft of the drive motor is connected to the rotating block through a coupling.

[0004] Although it achieves the goal of putting the required mixing material into the top of the feeding frame of the device, the raw material enters the metering wheel in the feeding frame and then enters the metering trough. Because the metering trough is set at an angle, the raw material accumulates at the angle and drives the metering wheel to rotate. This makes it easy for the device to ensure the consistency of the mixing amount when feeding different raw materials, thereby enhancing the mixing effect of the device, improving the use effect of the device, and improving the practicality of the device.

[0005] However, the existing mixing equipment does not solve the problem that it is not convenient to input raw materials sequentially for mixing and to flexibly adjust the discharge position of materials during use. It is not conducive to the rapid input and flexible adjustment of material discharge, which affects the convenience of raw material input and the flexibility of output. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum nitrogen-sealing mixing device for bisphenol A phenolic special epoxy resin, in order to solve the problem mentioned in the background art that the mixing device is not convenient for sequentially inputting raw materials for mixing and flexibly adjusting the material discharge position, which is not conducive to the rapid input and flexible adjustment of material discharge, thus affecting the convenience of raw material input and the flexibility of output.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vacuum nitrogen-sealing mixing device for bisphenol A phenolic special epoxy resin, comprising a support frame and a mixing tank. The mixing tank is installed at the top of the support frame, and electric push rods are symmetrically installed at the top of the mixing tank. Each electric push rod has a push arm installed at its output end. A limiting ring is provided above the mixing tank, and the limiting ring is connected to the push arm. A first toothed ring is slidably installed inside the limiting ring. A placement plate is installed inside the first toothed ring, and multiple sets of storage tanks with equal spacing are installed inside the placement plate. A stepper motor is installed on the outer wall of the limiting ring, and a first gear is installed at the output end of the stepper motor, and the first gear meshes with the first toothed ring.

[0008] Preferably, a stirring motor is installed inside the mixing tank, and a stirring rack is installed at the output end of the stirring motor.

[0009] Preferably, a connecting pipe is installed at the bottom of the mixing tank, and a feed pipe is movably installed inside the connecting pipe.

[0010] Preferably, an adjustment motor is installed on the outer wall of the connecting pipe, and a drive shaft is installed at the output end of the adjustment motor.

[0011] Preferably, a second toothed ring is mounted on the surface of the feed pipe, and a second gear is fitted on the surface of the drive shaft, and the second gear meshes with the second toothed ring.

[0012] Preferably, a discharge pipe is installed at the bottom end of the feed pipe, and a spiral blade is movably installed inside the discharge pipe.

[0013] Preferably, a servo motor is installed on the outer wall of the discharge pipe, and the output end of the servo motor is connected to the spiral blade.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the mixing equipment not only realizes the convenient sequential input of raw materials for mixing and flexibly adjusts the discharge position of materials, facilitating the rapid input and flexible adjustment of material discharge, but also improves the convenience of raw material input and the flexibility of output.

[0015] (1) The first gear is driven to rotate by the stepper motor, which in turn drives the first gear ring to rotate inside the limiting ring. The first gear ring drives the placement plate and the storage tank to rotate, so that the storage tank rotates to the door position in sequence. The electric push rod drives the push arm to retract, and the push arm drives the limiting ring, the first gear ring, the placement plate, and the storage tank to move downwards, so that the storage tank moves into the door. Then, the solenoid valve inside the corresponding storage tank is opened, so that the raw material in the storage tank enters the mixing tank. After the feeding is completed, the solenoid valve is closed, and the electric push rod is opened in the reverse direction, so that the electric push rod drives it to reset. Then, the above operation is repeated. Different raw materials are added, and then the door is closed to create a vacuum inside the mixing tank. The stirring motor drives the stirring frame to rotate, which mixes the raw materials. After mixing, the solenoid valve at the bottom of the mixing tank is opened, and the material enters the discharge pipe through the connecting pipe and the feed pipe. The servo motor drives the spiral blades to rotate, which moves the material and discharges it through the discharge pipe, thus completing the epoxy resin mixing process. This method allows for convenient sequential input of raw materials for mixing, reducing manual feeding, minimizing manpower waste, and improving the convenience of raw material input.

[0016] (2) When it is necessary to adjust the position of material output, the adjustment motor drives the drive shaft to rotate, the drive shaft drives the second gear to rotate, the second gear drives the feed pipe to rotate through the second gear ring, and the feed pipe drives the discharge pipe to rotate, thereby adjusting the discharge position of the discharge pipe to facilitate the discharge of materials from different positions, realizing convenient and flexible adjustment of the material discharge position and improving the flexibility of material output.

[0026] Example 1

[0027] Please see Figure 1-5This utility model provides an embodiment of a bisphenol A phenolic special epoxy resin vacuum nitrogen sealing mixing device, including a support frame 1 and a mixing tank 2. The mixing tank 2 is installed at the top of the support frame 1, and electric push rods 10 are symmetrically installed at the top of the mixing tank 2. The electric push rods 10 serve as power drives. Push arms 9 are installed at the output ends of the electric push rods 10. A limit ring 8 is provided above the mixing tank 2, and the limit ring 8 is connected to the push arms 9. A first toothed ring 5 is slidably installed inside the limit ring 8. A placement plate 6 is installed inside the first toothed ring 5. Multiple sets of storage tanks 7 with equal spacing are installed inside the placement plate 6. A stepper motor 3 is installed on the outer wall of the limit ring 8. The stepper motor 3 serves as power drives. A first gear 4 is installed at the output end of the stepper motor 3, and the first gear 4 meshes with the first toothed ring 5.

[0028] The mixing tank 2 is equipped with a stirring motor 12, which serves as a power drive, and a stirring rack 13 is installed at the output end of the stirring motor 12.

[0029] A connecting pipe 14 is installed at the bottom of the mixing tank 2, and a feed pipe 15 is movably installed inside the connecting pipe 14;

[0030] Multiple raw materials are poured into the interiors of multiple storage tanks 7. When epoxy resin needs to be mixed for production, the hatch of the mixing tank 2 is opened, and then the stepper motor 3 is turned on. The stepper motor 3 drives the first gear 4 to rotate. Under the mutual meshing of the first gear 4 and the first gear ring 5, and the sliding cooperation between the first gear ring 5 and the limiting ring 8, the first gear 4 drives the first gear ring 5 to rotate inside the limiting ring 8. The first gear ring 5 drives the placement plate 6 and the storage tank 7 to rotate, so that the storage tank 7 rotates sequentially to the hatch position. Then, the electric push rod 10 is opened, which drives the push arm 9 to retract. The push arm 9 drives the limiting ring 8, the first gear ring 5, the placement plate 6, and the storage tank 7 to move downwards, so that the storage tank 7 moves into the hatch. Then, the solenoid valve inside the corresponding storage tank 7 is opened, so that the raw materials in the storage tank 7 enter the interior of the mixing tank 2, and the material is added. After completion, close the solenoid valve and reverse the electric push rod 10 to reset it. Repeat the above operation to add different raw materials. Then close the door and evacuate the mixing tank 2 to a vacuum state. Turn on the stirring motor 12, which drives the stirring frame 13 to rotate. The stirring frame 13 stirs and mixes the raw materials. After mixing, open the solenoid valve at the bottom of the mixing tank 2. The material enters the discharge pipe 11 through the connecting pipe 14 and the feed pipe 15. Turn on the servo motor 17, which drives the spiral blade 16 to rotate. The spiral blade 16 moves the material and discharges it from the discharge pipe 11, thus completing the mixing production of epoxy resin. This method allows for convenient sequential input of raw materials for mixing, reducing manual feeding, minimizing manpower waste, and improving the convenience of raw material input.

[0031] An adjustment motor 21 is installed on the outer wall of the connecting pipe 14. The adjustment motor 21 plays the role of power drive, and a drive shaft 20 is installed at the output end of the adjustment motor 21.

[0032] A second toothed ring 18 is mounted on the surface of the feed pipe 15, and a second gear 19 is fitted on the surface of the drive shaft 20. The second gear 19 meshes with the second toothed ring 18. A discharge pipe 11 is mounted at the bottom end of the feed pipe 15, and a spiral blade 16 is movably mounted inside the discharge pipe 11.

[0033] A servo motor 17 is installed on the outer wall of the discharge pipe 11. The servo motor 17 serves as a power drive, and the output end of the servo motor 17 is connected to the spiral blade 16.

[0034] When the material output position needs to be adjusted, the adjustment motor 21 is turned on, which drives the drive shaft 20 to rotate. The drive shaft 20 drives the second gear 19 to rotate. With the meshing of the second gear 19 and the second gear ring 18, and the movable cooperation between the feed pipe 15 and the connecting pipe 14, the second gear 19 drives the feed pipe 15 to rotate through the second gear ring 18. The feed pipe 15 drives the discharge pipe 11 to rotate, thereby adjusting the discharge position of the discharge pipe 11 to facilitate the discharge of materials from different positions. This achieves convenient and flexible adjustment of the material discharge position and improves the flexibility of material output.

[0035] Work steps

[0036] The stepper motor 3 drives the first gear 4 to rotate, which in turn drives the first gear ring 5 to rotate inside the limiting ring 8. The first gear ring 5 drives the placement plate 6 and the storage tank 7 to rotate, so that the storage tank 7 rotates sequentially to the door position. The electric push rod 10 drives the push arm 9 to retract, and the push arm 9 drives the limiting ring 8, the first gear ring 5, the placement plate 6, and the storage tank 7 to move downwards, so that the storage tank 7 moves into the door. Then, the solenoid valve inside the corresponding storage tank 7 is opened, so that the raw material in the storage tank 7 enters the mixing tank 2. After the material is added, the solenoid valve is closed, and the electric push rod 10 is opened in the reverse direction, so that it resets. The above operation is repeated to add different raw materials. Then, the door is closed, and the inside of the mixing tank 2 is evacuated to a vacuum state. The stirring motor 12 drives the stirring frame 13 to rotate, and the stirring... The frame 13 is used to stir and mix the raw materials. After mixing, the solenoid valve at the bottom of the mixing tank 2 is opened, and the material enters the discharge pipe 11 through the connecting pipe 14 and the feed pipe 15. The servo motor 17 drives the spiral blade 16 to rotate, and the spiral blade 16 drives the material to move and be discharged from the discharge pipe 11, thus completing the mixing and production of epoxy resin. When it is necessary to adjust the material output position, the adjusting motor 21 drives the drive shaft 20 to rotate, and the drive shaft 20 drives the second gear 19 to rotate. The second gear 19 drives the feed pipe 15 to rotate through the second gear ring 18, and the feed pipe 15 drives the discharge pipe 11 to rotate, thereby adjusting the discharge position of the discharge pipe 11 to facilitate the discharge of material from different positions. The above is the complete usage of the bisphenol A phenolic special epoxy resin vacuum nitrogen sealing mixing equipment.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
