[0024] Example 1, such as Figure 1-6As shown, the automatic feeding and dispensing equipment for phenolic resin main material and curing agent includes a mixing tank 3, which is a vertically arranged cylindrical structure. Multiple feeding sections 4 are arranged circumferentially at the upper end of the mixing tank 3, and the discharge ends of the feeding sections 4 are all connected to the internal chamber of the mixing tank 3. A discharge section 8 is located at the center of the lower end of the mixing tank 3, and the inlet end of the discharge section 8 is connected to the internal chamber of the mixing tank 3. A mixing device 6 for multi-layer three-dimensional mixing is installed in the internal chamber of the mixing tank 3. The mixing device 6 can fully mix the phenolic resin main material and curing agent fed in by the feeding sections 4 before discharging them from the discharge section 8. A fixing frame 1 is fitted onto the outer wall of the mixing tank 3. The fixing frame 1 and the mixing tank 3 are detachably connected by multiple mounting seats 2. One end of the mounting seat 2 is fixedly connected to the outer wall of the mixing tank 3, and the other end of the mounting seat 2 is fixedly connected to the inner wall of the fixing frame 1. The bottom of the fixing frame 1 is provided with multiple support legs, and each support leg is fixed to the ground by expansion bolts. The fixing frame 1 can provide a stable vertical support effect for the mixing tank 3. The bottom of the mixing tank 3 is coaxially connected to a connecting cylinder 5. A cover is bolted to the lower opening of the connecting cylinder 5, which controls the opening and closing of the lower end of the connecting cylinder 5. A stirring shaft 61 is vertically rotatably mounted inside the connecting cylinder 5. The upper end of the stirring shaft 61 extends upward into the internal cavity of the mixing tank 3. Multiple transverse stirring rods 63 are fixedly connected to the radial surface of the stirring shaft 61. The transverse stirring rods 63 are spaced apart along the circumference and axial direction of the stirring shaft 61. A drive unit is mounted on the outer wall of the connecting cylinder 5. The drive unit provides power for the rotation of the stirring shaft 61, driving the transverse stirring rods 63 to rotate and stir inside the mixing tank 3. On the radial surface of the stirring shaft 61, a rotating stirring part 64 is rotatably mounted on each side of the transverse stirring rod 63. The rotating stirring part 64 and the stirring shaft 61 are connected by a rotating fit. During the rotation of the stirring shaft 61 around its own axis, it can drive the rotating stirring part 64 to make a circumferential revolution motion. At the same time, the rotating stirring part 64 will generate a rotation motion around its own axis. Through the combination of revolution and rotation, the material inside the mixing tank 3 can be further stirred and mixed. The rotary stirring unit 64 includes a horizontal shaft and multiple connecting rods fixed radially and vertically along the horizontal shaft. The horizontal shaft is arranged in the horizontal direction and rotates in cooperation with the stirring shaft 61. The horizontal shaft can rotate around its own horizontal axis. A roller 65 is fixedly connected to the end of the horizontal shaft. A traveling ring 66 is fixedly connected circumferentially to the side wall of the internal chamber of the mixing tank 3. The circumferential surface of the roller 65 maintains rolling contact with the upper end surface of the traveling ring 66. When the stirring shaft 61 rotates, it will drive the roller 65 to roll circumferentially along the upper end surface of the traveling ring 66, thereby driving the horizontal shaft to rotate around its own horizontal axis. The rotation of the horizontal shaft drives the connecting rods to perform vertical tumbling and stirring inside the mixing tank 3. This, together with the horizontal rotation stirring of the horizontal stirring rod 63, forms a three-dimensional multi-stage stirring and mixing structure.The drive unit includes a stirring motor 67 fixed on the outer wall of the connecting cylinder 5. The output shaft of the stirring motor 67 is arranged horizontally and extends axially into the interior of the connecting cylinder 5. The output shaft of the stirring motor 67 and the stirring shaft 61 are connected by a gear transmission unit 68. The gear transmission unit 68 consists of two meshing bevel gears. One bevel gear is fixed to the end of the output shaft of the stirring motor 67, and the other bevel gear is fixed to the lower radial surface of the stirring shaft 61. When the stirring motor 67 is working, the horizontal rotational motion of the output shaft can be converted into the rotational motion of the stirring shaft 61 around its own vertical axis through the meshing transmission of the two bevel gears. A conveying hopper 69 is fixedly connected to the internal chamber of the connecting cylinder 5. The conveying hopper 69 has an inverted conical structure, with its large end facing upward and connected to the bottom of the mixing tank 3, and its small end facing downward and towards the discharge section 8. The conveying hopper 69 can guide the material falling from the mixing tank 3 into the connecting cylinder 5 in a centripetal direction and direct the material to the discharge section 8. A stirring auger 62 is vertically arranged inside the conveying hopper 69. The stirring auger 62 is coaxially fixedly connected to the stirring shaft 61 and can rotate synchronously with the rotation of the stirring shaft 61. When the stirring shaft 61 rotates clockwise, the rotation direction of the stirring auger 62 is opposite to the natural falling direction of the material, which can effectively block the material from entering the connecting cylinder 5. When the stirring shaft 61 rotates counterclockwise, the rotation direction of the stirring auger 62 is the same as the natural falling direction of the material, which can vertically convey the material inside the mixing tank 3 to the inside of the connecting cylinder 5. Both the feeding section 4 and the discharging section 8 adopt the structure of an auger conveyor assembly, which can complete the axial feeding movement in the vertical direction. The feeding section 4 can axially feed the phenolic resin main material and the curing agent into the internal chamber of the mixing tank 3 respectively. The lower end of the discharging section 8 is equipped with a discharge pipe 9 installed vertically and coaxially. The inlet end of the discharge pipe 9 is connected to the outlet end of the discharging section 8. The material that has been mixed by the auger conveyor of the discharging section 8 can be discharged axially downward along the discharge pipe 9. A vibration device 7 is mounted on the upper end surface of the traveling ring 66. The position of the vibration device 7 corresponds to the rolling path of the roller 65 on the traveling ring 66. When the roller 65 rolls circumferentially along the upper end surface of the traveling ring 66 and passes the vibration device 7, it can trigger the vibration device 7 to generate a vibration effect. This vibration will be transmitted along the traveling ring 66 to the entire side wall of the mixing tank 3, and finally realize the vibration action of the entire mixing tank 3.The vibration device 7 includes a mounting groove 71 formed on the upper end face of the traveling ring 66. A compression cylinder 72 is fixedly connected vertically inside the mounting groove 71. An elastic cover 75 is fixedly connected to the upper end face of the traveling ring 66 at the opening of the mounting groove 71. The upper input end of the compression cylinder 72 is in contact with the lower end face of the elastic cover 75. A spring 74 is sleeved on the outer wall of the compression cylinder 72. The upper end of the spring 74 is fixedly connected to the lower end face of the elastic cover 75, and the lower end of the spring 74 is fixedly connected to the radial surface of the compression cylinder 72. The outlet of the compression cylinder 72 is connected to an impact cylinder 73, which is fixedly connected horizontally to the mounting groove 72. When the roller 65 rolls on the upper surface of the elastic cover 75 on the inner wall of the mounting groove 71, it applies downward pressure to the elastic cover 75. This pressure causes the elastic cover 75 to move downward and compress the compression cylinder 72. The compressed air inside the compression cylinder 72 enters the impact cylinder 73 along the air passage, driving the output shaft of the impact cylinder 73 to extend outward in the horizontal direction and impact the inner wall of the mounting groove 71, thereby generating vibration. After the roller 65 passes the elastic cover 75, the elastic restoring force of the spring 74 will drive the elastic cover 75 to move upward to achieve reset. At the same time, it drives the input end of the compression cylinder 72 to move upward, so that the compression cylinder 72 returns to its initial working state.
[0025] Working principle: The feeding unit 4 feeds the phenolic resin main material and curing agent vertically into the internal chamber of the mixing tank 3 via an auger conveyor. After the stirring motor 67 starts, its output shaft rotates horizontally. The horizontal rotation is converted into the vertical rotation of the stirring shaft 61 by the gear transmission unit 68 composed of two meshing bevel gears. The stirring shaft 61 drives multiple horizontal stirring rods 63 to rotate horizontally in the mixing tank 3. While the stirring shaft 61 rotates, it drives the rotating stirring unit 64 to rotate synchronously in the circumferential direction. During the rotation, the roller 65 at the end of the horizontal shaft rolls along the upper surface of the traveling ring 66, thereby driving the horizontal shaft to rotate around its own horizontal axis. The horizontal shaft drives the connecting rod to rotate vertically in the mixing tank 3, forming a three-dimensional multi-stage stirring structure with the horizontal stirring rods 63, achieving thorough mixing of the phenolic resin main material and curing agent. As the roller 65 rolls on the traveling ring 66, it crushes the elastic cover 75, triggering the vibration device 7 to work. The elastic cover 75 moves downward under pressure, compressing the compression cylinder 72. The compressed air in the compression cylinder 72 enters the impact cylinder 73 and pushes its output shaft to impact the inner wall of the mounting groove 71, generating vibration. The vibration is transmitted to the entire mixing tank 3 through the traveling ring 66, preventing the material from sticking to the inner wall of the mixing tank 3. After the roller 65 passes, the elastic restoring force of the spring 74 will drive the elastic cover 75 and the compression cylinder 72 to reset, ensuring the cyclical operation of the vibration device 7. During the mixing process, the stirring shaft 61 rotates forward. At this time, the rotation direction of the stirring auger 62 is opposite to the direction of material falling, forming a barrier against the material and ensuring that the material has sufficient mixing time in the mixing tank 3. After the material is mixed, the stirring shaft 61 switches to reverse rotation, and the stirring auger 62 rotates synchronously with the stirring shaft 61, conveying the mixed material in the mixing tank 3 vertically downward to the connecting cylinder 5. After the material is guided centripetally through the inverted conical conveying bucket 69, it enters the discharge section 8. The discharge section 8 conveys the material into the discharge pipe 9 through the auger, and finally the material is discharged through the discharge pipe 9. The whole process realizes the integrated operation of automatic feeding, three-dimensional stirring, vibration anti-sticking and controllable discharge of phenolic resin main material and curing agent.
