Description

Technical Field

[0001] This utility model relates to the field of epoxy resin manufacturing technology, and in particular to a stirring and mixing device for epoxy resin production. Background Technology

[0002] Epoxy resins generally refer to organic polymer compounds containing two or more epoxy groups in their molecules. They can be used as anti-corrosion paints, metal primers, and insulating paints, and can also be used as adhesives in the automotive, electronics, and electrical industries.

[0003] Chinese utility model patent CN218854025U discloses a mixing device for epoxy resin production. By using a combination of a first placement cavity, a connecting rod, a threaded connecting column, a second stirring blade, a slot, a plug-in rod, a compression spring, a movable groove, and a first threaded hole, the length of the stirring rod can be adjusted, enabling the entire mixing device to perform mixing work on a relatively tall mixing drum. At the same time, the connecting rod and the second stirring blade are easy to disassemble and place when not in use.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: When the device stirs the epoxy resin, the stirring rod rotates, causing the material inside the stirring drum to form a rotational inertial flow, resulting in insufficient uniform mixing of the curing agent and epoxy resin. At the same time, since the height of the stirring rod remains constant, there is less material exchange between different height layers when the epoxy resin and curing agent are mixed, resulting in poor mixing effect of the device and affecting the overall discharge effect of the device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a stirring and mixing device for epoxy resin production.

[0006] This utility model is achieved by the following technical solution: a mixing device for epoxy resin production, including a box body, a vacuum pump installed on the top of the box body, a telescopic tube fixedly connected to the output end of the vacuum pump, the outer side of the telescopic tube being connected through to the top of the box body, a lifting component installed on the top of the box body, and a mixing component installed inside the box body.

[0007] The lifting assembly includes two support plates fixedly connected to the top of the box body. A rotating rod is installed between the two support plates. A drive motor is fixedly connected to one end of the rotating rod. A cam is sleeved on the outside of the rotating rod. A U-shaped frame abuts against the surface of the cam. Two lifting rods are fixedly connected to the bottom of the U-shaped frame. A lifting plate is fixedly connected to the bottom of the lifting rod. Lifting frames are fixedly connected to both ends of the lifting plate. A stirring cylinder is fixedly connected to the bottom of the lifting frame. The top of the stirring cylinder is connected to the bottom end of the telescopic tube.

[0008] The stirring assembly includes a long rod with its two ends rotatably connected to both sides of the inner wall of the box. Two connecting gears are sleeved on the surface of the long rod, and the surfaces of the connecting gears mesh with the interior of the lifting frame. A helical gear A is sleeved on the surface of the long rod, and a helical gear B is meshed with the surface of helical gear A. Support rods are fixedly connected at equal intervals to the surface of the intermediate shaft of helical gear B.

[0009] As a further improvement to the above solution, a mounting bearing is installed on the outer side of the intermediate shaft of the helical gear B, and a long strip plate is fixedly connected to the inner wall of the housing. The outer side of the mounting bearing is installed inside the long strip plate, which ensures the normal rotation of the intermediate shaft of the helical gear B.

[0010] As a further improvement to the above solution, the top of the stirring cylinder is provided with a through-hole for the intermediate shaft of helical gear B to pass through, ensuring the normal operation of the intermediate shaft of helical gear B.

[0011] As a further improvement to the above solution, the front of the mixing drum is connected to a discharge pipe, and the top of the mixing drum is connected to a telescopic feed pipe. The surface of the telescopic feed pipe is connected to the top of the box body, and a sealing cover is installed on the top of the telescopic feed pipe to facilitate the addition of materials into the mixing drum.

[0012] As a further improvement to the above solution, the lifting frame includes a return plate, and teeth are fixedly connected at equal intervals on one side of the inner wall of the return plate. The surface of the teeth meshes with the surface of the connecting gear, which facilitates the rotation of the connecting gear.

[0013] As a further improvement to the above solution, a mounting base is installed at the bottom of the drive motor, and the back of the mounting base is fixedly connected to the front of the support plate, ensuring the normal operation of the drive motor.

[0014] As a further improvement to the above solution, two limiting ports are provided on the top of the housing, and the lifting rod is slidably disposed inside the limiting ports to ensure the normal operation of the lifting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a lifting component, allows the lifting frame to reciprocate as it moves up and down. This reciprocates the connecting gear, causing the long rod to reciprocate the helical gear A. Under the action of the helical gear A, the helical gear B reciprocates and rotates to stir the material inside the mixing drum. This avoids the unidirectional rotation causing the material to flow due to rotational inertia, resulting in more collisions between the material and the intermediate shaft of the helical gear B, thus improving the uniformity of the mixing. At the same time, because the mixing drum moves up and down vertically, the intermediate shaft of the helical gear B can stir different levels of material, improving the mixing effect of the device.

[0017] 2. This utility model, by setting up a stirring assembly, opens the sealing cover and introduces the material into the mixing drum through the telescopic feed pipe. Then, the drive motor is started, causing the rotating rod to rotate. Under the action of the rotating rod, the cam continuously strikes the return frame, causing the return frame to reciprocate vertically. This causes the lifting rod to move up and down through the lifting plate, which in turn causes the mixing drum to move up and down, resulting in the material inside the mixing drum vibrating up and down. This achieves the exchange of materials inside the mixing drum, making the mixing of materials more uniform. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example:

[0025] Please combine Figure 1-3 This embodiment of an epoxy resin production mixing device includes a housing 1, a vacuum pump 2 installed on the top of the housing 1, a telescopic pipe 3 fixedly connected to the output end of the vacuum pump 2, the outer side of the telescopic pipe 3 being connected through to the top of the housing 1, a lifting assembly installed on the top of the housing 1, and a mixing assembly installed inside the housing 1.

[0026] The lifting assembly is used to move the mixing drum 11 up and down. The lifting assembly includes two support plates 4 fixedly connected to the top of the box body 1. A rotating rod 5 is installed between the two support plates 4. A drive motor is fixedly connected to one end of the rotating rod 5. A mounting base is installed at the bottom of the drive motor. The back of the mounting base is fixedly connected to the front of the support plate 4 to ensure the normal operation of the drive motor. A cam 6 is sleeved on the outside of the rotating rod 5. A U-shaped frame 7 abuts against the surface of the cam 6. Two lifting rods 8 are fixedly connected to the bottom of the U-shaped frame 7. Two limit openings are opened at the top of the box body 1. The lifting rod 8 is slidably set inside the limiting port to ensure the normal operation of the lifting rod 8. The bottom of the lifting rod 8 is fixedly connected to the lifting plate 9. Both ends of the lifting plate 9 are fixedly connected to the lifting frame 10. The bottom of the lifting frame 10 is fixedly connected to the mixing drum 11. The front of the mixing drum 11 is connected to the discharge pipe. The top of the mixing drum 11 is connected to the telescopic feed pipe. The surface of the telescopic feed pipe is connected through the top of the box 1. The top of the telescopic feed pipe is equipped with a sealing cover to facilitate the addition of materials into the mixing drum 11. The top of the mixing drum 11 is connected to the bottom of the telescopic pipe 3.

[0027] The mixing assembly is used to mix and stir materials. The mixing assembly includes a long rod 12, with both ends of the long rod 12 rotatably connected to the two sides of the inner wall of the housing 1. Two connecting gears 13 are sleeved on the surface of the long rod 12. The lifting frame 10 includes a return plate, with teeth fixedly connected at equal intervals on one side of the inner wall of the return plate. The surface of the teeth meshes with the surface of the connecting gears 13, facilitating the rotation of the connecting gears 13. The surface of the connecting gears 13 meshes with the interior of the lifting frame 10. A helical gear A14 is sleeved on the surface of the long rod 12, and a helical gear B15 is meshed with the surface of the helical gear A14. The top of the mixing drum 11 has a through-hole for the intermediate shaft of the helical gear B15 to pass through, ensuring the normal operation of the intermediate shaft of the helical gear B15. Support rods are fixedly connected at equal intervals on the surface of the intermediate shaft of the helical gear B15. A mounting bearing is installed on the outer side of the intermediate shaft of the helical gear B15. A long strip plate is fixedly connected to the inner wall of the housing 1, and the outer side of the mounting bearing is installed inside the long strip plate, ensuring the normal rotation of the intermediate shaft of the helical gear B15.

[0028] The implementation principle of the mixing device for epoxy resin production in this embodiment is as follows: Open the sealing cover and introduce the material into the mixing drum 11 through the telescopic feed pipe. Then start the drive motor to make the rotating rod 5 rotate. Under the action of the rotating rod 5, the cam 6 continuously hits the return frame 7, causing the return frame 7 to move back and forth vertically. This causes the lifting rod 8 to move up and down with the lifting frame 10 through the lifting plate 9, thereby causing the mixing drum 11 to move up and down. This causes the material in the mixing drum 11 to vibrate up and down, realizing the exchange of materials in the mixing drum 11 and making the mixing of materials more uniform.

[0029] During the up-and-down movement of the lifting frame 10, the lifting frame 10 will reciprocate and deflect the connecting gear 13, thereby causing the long rod 12 to reciprocate and deflect the helical gear A14. Under the action of the helical gear A14, the helical gear B15 reciprocates and rotates to stir the material inside the mixing drum 11, avoiding the unidirectional rotation that causes the material to flow due to rotational inertia. This results in more collisions between the material and the intermediate shaft of the helical gear B15, improving the uniformity of the mixing. At the same time, because the mixing drum 11 moves up and down in the vertical direction, the intermediate shaft of the helical gear B15 can stir materials at different levels, improving the mixing effect of the device.

[0030] During use, the vacuum pump 2 can perform a vacuuming operation inside the stirring drum 11, thereby reducing the formation of air bubbles inside the device and reducing the impact of air on product cooling.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
