AI Technical Summary
The existing powder forming machine feeding mechanism in the multi-mold groove structure is prone to uneven powder material, which leads to an increase in the defect rate. At the same time, frequent shaking of the feeding box will accelerate wear and reduce service life.
The feeding box is equipped with an active rotating rod and a driven rotating rod, which are connected to a scraper via a transmission toothed belt. The scraper is driven by a servo motor to move back and forth inside the feeding box, thereby leveling the powder material and preventing the feeding box from shaking.
It achieves uniform distribution of powder materials, reduces the defect rate, and extends the service life of the feeding box.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of powder forming machine feeding equipment, specifically a powder forming machine feeding mechanism that can flatten materials. Background Technology
[0002] A powder molding machine is a mechanical device specifically designed to compress powdered materials into molded shapes. Its working principle is based on physical mechanics principles; by applying a certain pressure and time, the powdered material undergoes plastic deformation within a mold, thereby obtaining a molded product with a specific shape, size, and density.
[0003] The feeding mechanism of a powder forming machine is used to deliver powder material to the die and allow the powder material to fall into the die groove, thus achieving feeding. In existing feeding mechanisms, after several feedings, especially with multi-groove dies, the powder material inside the feeding box is prone to uneven distribution. If the feeding box is not shaken back and forth several times, some areas will lack sufficient powder, leading to an increased defect rate. However, shaking the feeding box back and forth causes excessive wear and tear, reducing its service life. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content
[0004] The purpose of this invention is to provide a feeding mechanism for a powder forming machine that can scrape the material evenly. By using a scraper that moves back and forth inside the feeding box, the powder material inside the feeding box can be scraped evenly, thereby reducing the defect rate. This structure can scrape the powder material evenly without shaking the feeding box, ensuring service life, thus solving the problems mentioned in the background art.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a feeding mechanism for a powder forming machine that can scrape materials, including a feeding box 1 and a scraping component;
[0023] The lower surface of the feeding box 1 is open, and the upper surface of the feeding box 1 is provided with a feeding interface 2, which is used to connect to the feeding hose.
[0024] The leveling assembly includes an active rotating rod 3, a driven rotating rod 4, a transmission toothed belt 5, a scraper 6, and a servo motor 7. The active rotating rod 3 and the driven rotating rod 4 are arranged in parallel inside the feeding box 1. Limiting grooves 8 are opened at both ends of the active rotating rod 3 and the driven rotating rod 4. Saw teeth are provided in the limiting grooves 8. Both ends of the active rotating rod 3 and the driven rotating rod 4, located at the limiting grooves 8, are connected to the transmission toothed belt 5. The two ends of the upper surface of the scraper 6 are connected to the lower part of the two transmission toothed belts 5 through connecting parts. The scraper 6 is densely covered with mesh holes to ensure that the powder material can pass through the mesh holes, preventing the scraper 6 from pushing the powder material to one side, thereby smoothly spreading the powder material evenly. The servo motor 7 is set on the outer surface of the feeding box 1. The output shaft of the servo motor 7 is connected to one end of the active rotating rod 3. A connecting seat 11 is set at the end of the feeding box 1 away from the servo motor 7. The connecting seat 11 is used to connect with the piston rod of the pneumatic / hydraulic cylinder that pushes and pulls the feeding box, thereby realizing the pushing out and retracting of the feeding box 1.
[0025] A copper sleeve 9 is provided at the end of the active rotating rod 3 away from the servo motor 7. A limit bolt 10 is provided at the end of the copper sleeve 9 of the active rotating rod 3 located in the feeding box 1. Copper sleeves 9 are provided at both ends of the driven rotating rod 4. Limit bolts 10 are provided at both ends of the driven rotating rod 4 located in the feeding box 1. The end of the limit bolt 10 has a smooth surface and is inserted and engaged with the corresponding copper sleeve 9. A square hole 12 is opened at one end of the active rotating rod 3. The output shaft of the servo motor 7 is engaged and connected with the square hole 12. This structure enables the servo motor 7 to drive the active rotating rod 3 to rotate.
[0026] Installation method and operating principle: First, place the two transmission toothed belts 5 onto the driving rod 3 and driven rod 4 respectively. Then, place the driving rod 3 and driven rod 4 together with the transmission toothed belts 5 into the feeding box 1. Next, install the servo motor 7 on the outer end of the feeding box 1 and insert the output shaft of the servo motor 7 into the square hole 12 of the driving rod 3. Insert the copper sleeve 9 at the other end of the driving rod 3 into the smooth part at the end of the limit bolt 10. Similarly, insert the copper sleeve 9 of the driven rod 4 into the smooth part at the end of the limit bolt 10. Finally, connect the top of the scraper 6 with the mesh to the bottom of the two transmission toothed belts 5 through the connector to complete the installation. Before use, connect the feed interface 2 to the feed pipe and connect it to the feeding cylinder or hydraulic cylinder through the connecting seat 11. In use, the powder material falls into the feeding box 1 from the feeding interface 2. The feeding box 1 moves to the female mold of the powder forming machine, and the powder falls into the mold groove. The feeding box 1 leaves the female mold, and the servo motor 7 is started. The servo motor 7 drives the active rotating rod 3 to rotate forward, and the scraper 6 moves laterally along the inside of the feeding box 1, thereby scraping the powder material evenly. When scraping the material again, the servo motor 7 drives the active rotating rod 3 to rotate in reverse, and the scraper 6 returns to the initial position, thus realizing the back-and-forth movement of the scraper 6. This utility model has a reasonable structure. The feeding box 1 is equipped with an active rotating rod 3 and a driven rotating rod 4. Two transmission toothed belts 5 are connected between the active rotating rod 3 and the driven rotating rod 4. The transmission toothed belts 5 are connected to the scraper 6. The active rotating rod 3 is driven by a servo motor 7 installed on the outside of the feeding box 1. The scraper 6, which moves back and forth inside the feeding box 1, can scrape the powder material inside the feeding box 1 to make it level, ensuring that the powder material can fall smoothly and evenly into the mold groove of the negative mold, thereby reducing the defect rate. With this structure, the powder material can be scraped evenly without shaking the feeding box 1, thus ensuring the service life.
