Description

Technical Field

[0001] This utility model relates to the field of resin tungsten processing technology, specifically to a raw material proportioning device for resin tungsten processing. Background Technology

[0002] Tungsten resin is a type of synthetic resin, a non-metallic mixture formed by combining tungsten with various polymers. The properties of the tungsten resin are determined by the properties of the polymers, with tungsten particles accounting for 60% by volume and 96% by weight. Tungsten resin is characterized by its high density, small volume, strong radiation resistance, non-toxicity, and environmental friendliness. It also possesses the advantages of resin products, such as ease of processing, high plasticity, corrosion resistance, good ductility, and low raw material cost. Therefore, it has a wide range of applications and is becoming increasingly popular, commonly used as a counterweight in products such as toy car counterweights, model airplane counterweights, and fishing gear counterweights.

[0003] In the existing technology, the production of resin tungsten requires mixing the raw materials according to the ratio. The mixing operation of resin tungsten is usually done manually. During the mixing process, each raw material needs to be weighed and then a fixed weight of raw materials is mixed together to process resin tungsten. This mixing operation is cumbersome and reduces the production efficiency of resin tungsten. Therefore, a raw material mixing device for resin tungsten processing is needed. Utility Model Content

Springs are fixedly connected to the outer sides of each limiting rod on the bottom wall of the mixing box. A collecting hopper is provided inside each mixing box. A discharge port is provided at the middle of both the collecting hopper and the bottom wall of the mixing box. A discharging hopper is fixedly connected to the bottom periphery of each discharging port. A discharging pipe is fixedly connected to the bottom end of each discharging hopper.

[0013] The beneficial effects of this utility model are:

[0014] 1. This raw material proportioning device for resin tungsten processing opens three sets of feeding valves when resin tungsten raw material proportioning is required, allowing the material inside the storage tank to enter the proportioning box through the feeding pipe. This increases the mass inside the proportioning box. As the material inside the proportioning box increases, it moves downward, causing the feeding switch, discharging switch, and U-shaped block at the bottom of the proportioning box to come into contact. The U-shaped block presses the feeding switch and discharging switch, thereby closing the top feeding valve and opening the bottom discharging valve, discharging a fixed mass of raw material from the proportioning box. This achieves automatic raw material proportioning and improves the efficiency of resin tungsten processing.

[0015] 2. This raw material proportioning device for resin tungsten processing, by rotating the threaded tube, causes the U-shaped block to move up and down during the rotation of the threaded tube. By adjusting the distance between the top of the U-shaped block and the feeding and discharging switches, the compression height of the spring can be controlled, thereby controlling the proportion and weight of the raw materials, thus improving the practicality of the automatic proportioning device.

[0023] Example: Figure 1-4 As shown, the present invention provides a raw material proportioning device for resin tungsten processing, including a mixing tank 1, and an automatic proportioning mechanism 2 is provided on the outside of the mixing tank 1.

[0024] The automatic proportioning mechanism 2 includes a mounting plate 3. Limiting rods 4 are slidably connected through and at each of the four corners of the mounting plate 3. The limiting rods 4 are fixedly connected to the four corners of the bottom wall of the mixing box 6. Springs 5 ​​are fixedly connected to the outer sides of the limiting rods 4 on the bottom wall of the mixing box 6. All four sets of springs 5 ​​are identical, compressing the springs 5 ​​to a fixed height as the material inside the mixing box 6 increases by a certain mass. A collecting hopper 7 is provided inside the mixing box 6. A discharge port 8 is provided in the middle of the bottom wall of the mixing box 6 and in the collecting hopper 7. The material inside the mixing box 6 is discharged through the discharge hopper 9 and the discharge pipe 10. A discharge hopper 9 is fixedly connected to the bottom of the discharge port 8, and a discharge pipe 10 is fixedly connected to the bottom of the discharge hopper 9. A discharge valve 11 is provided at the top of the outer periphery of the discharge pipe 10. Opening the discharge valve 11... The feeding pipe 10 can be connected. A feeding switch 16 is provided on the middle of the bottom wall of the mixing box 6 away from the mixing tank 1, and a feeding switch 17 is provided on the middle of the bottom wall of the mixing box 6 near the mixing tank 1. The feeding pipe 10 passes through and is slidably connected to the inside of the threaded pipe 12. During the rotation of the threaded pipe 12, the U-shaped block 14 can move up and down. The middle of the outer periphery of the threaded pipe 12 is threaded with the U-shaped block 14. The top left and right ends of the U-shaped block 14 pass through and are slidably connected to the inside of the opening 15. The feeding pipe 10 can move up and down inside the threaded pipe 12. Multiple sets of annularly distributed U-shaped rods 21 are fixedly connected to the middle of the outer periphery of the mixing tank 1. The top of the U-shaped rods 21 is fixedly connected to the storage tank 22. The storage tank 22 stores the resin tungsten raw material used for batching.

[0025] The mounting plates 3 are all fixedly connected to the top of the outer wall of the mixing tank 1 and distributed in a ring. The other end of the springs 5 ​​are fixedly connected to the four corners of the top wall of the mounting plate 3. The mounting plate 3 provides space for the installation of the ingredient box 6.

[0026] The openings 15 are respectively located on the left and right sides of the middle of the bottom wall of the mounting plate 3. The left and right ends of the U-shaped block 14 are respectively located at the bottom of the loading switch 16 and the unloading switch 17. When the loading switch 16 is pressed, the loading valve 24 is closed, and when the unloading switch 17 is pressed, the unloading valve 11 is opened.

[0027] The threaded tubes 12 are all connected to the middle of the bottom wall of the mounting plate 3 through and rotating, and the discharge valves 11 are all located at the top of the mounting plate 3. During the rotation of the threaded tubes 12, the U-shaped blocks 14 can move up and down.

[0028] The mixing tank 1 has support plates 18 fixedly connected to both the left and right sides of the bottom wall. A discharge pipe 19 is fixedly connected through the middle of the bottom wall of the mixing tank 1. A sealing cover 20 is fixedly connected to the bottom end of the discharge pipe 19. The sealing cover 20 can seal the discharge pipe 19. After opening the sealing cover 20, the material inside the mixing tank 1 can be discharged.

[0029] The mixing tank 1 has multiple sets of annularly distributed feed inlets 25 on its upper outer periphery. Each feed inlet 25 is fixedly connected to a guide rail 13. The output end of the discharge pipe 10 is located directly above the guide rail 13. The material discharged from the discharge pipe 10 falls directly above the guide rail 13 and then enters the feed inlet 25 under the guidance of the guide rail 13.

[0030] The bottom wall of the storage hopper 22 is connected to a feeding pipe 23 through and fixedly connected. The feeding pipe 23 is equipped with a feeding valve 24 in the middle. The output end of the feeding pipe 23 is located directly above the mixing box 6. The material discharged from the feeding pipe 23 can fall accurately into the mixing box 6.

[0031] Working principle: When resin tungsten raw material proportioning is required, the threaded tube 12 is rotated. During the rotation of the threaded tube 12, the U-shaped block 14 moves up and down. Adjusting the distance between the top of the U-shaped block 14 and the feeding switch 16 and the discharging switch 17 allows control of the compression height of the spring 5, thereby controlling the proportion and weight of the raw material. Then, the three sets of feeding valves 24 are opened, allowing the material inside the storage tank 22 to enter the mixing box 6 through the feeding tube 23, thus increasing the mass inside the mixing box 6. As the material inside the mixing box 6 increases, it continues to move downward, causing the feeding switch 16 at the bottom of the mixing box 6 to contact the discharging switch 17 and the U-shaped block 14. The U-shaped block 14 presses the feeding switch 16 and the discharging switch 17, thereby closing the top feeding valve 24 and opening the bottom discharging valve 11, discharging a fixed mass of raw material from the mixing box 6, thus realizing the automatic proportioning operation of raw materials.
