Technical Field

[0001] This utility model relates to the field of powder equipment, and in particular to a powder weighing hopper with an anti-clogging structure. Background Technology

[0002] In production, it is often necessary to weigh and convey powders, and powder weighing hoppers are an important piece of equipment for this process. However, traditional powder weighing hoppers often experience problems such as powder clumping and clogging of the discharge port, affecting production efficiency and product quality. In addition, uneven distribution of powder within the weighing hopper can also lead to inaccurate weighing, further affecting subsequent production processing. Therefore, a powder weighing hopper with an anti-clogging structure is proposed. Utility Model Content

[0020] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1-4As shown, this utility model provides a powder weighing hopper with an anti-clogging structure, including a weighing hopper 1 and a support frame 2. A sealing plate 3 is fixedly connected to the top of the weighing hopper 1. A motor cover 4, on which a first motor 6 and a second motor 7 are installed, and a feeding hopper 5 are fixedly connected to the sealing plate 3. The sealing plate 3 also has a through hole, and a transmission cover 11 is provided at the through hole. Several bearings are installed inside the transmission cover 11. A first sprocket 12 is sleeved inside the transmission cover 11. The first sprocket 12 is connected to a second sprocket 13 through a chain 14. The second sprocket 13 is sleeved on the output shaft of the first motor 6. An agitator is fixedly connected to the bottom of the first sprocket 12. A guide is detachably connected to the output shaft of the second motor 7. The agitator and the guide cooperate to stir the powder in the weighing hopper 1 evenly and discharge it after preventing clogging.

[0022] The powder weighing hopper with an anti-clogging structure consists of a weighing hopper 1 and a support frame 2. A sealing plate 3 is fixedly connected to the top of the weighing hopper 1. A motor cover 4 is fixedly connected to the sealing plate 3 on one side, and a first motor 6 and a second motor 7 are installed inside the motor cover 4. A feeding hopper 5 is also fixedly connected to the sealing plate 3. The sealing plate 3 has a through hole, and a transmission cover 11 is installed at the through hole. Multiple bearings are installed inside the transmission cover 11, and a first sprocket 12 is sleeved inside the transmission cover 11. The first sprocket 12 is connected to a second sprocket 13 sleeved on the output shaft of the first motor 6 through a chain 14. An agitator is fixedly connected below the first sprocket 12, and a guide is detachably connected to the output shaft of the second motor 7. The agitator and guide unit work together to stir the powder inside the weighing hopper 1, ensuring uniformity and preventing blockages. This allows the processed powder to be discharged smoothly. Furthermore, the agitator breaks up any clumps that may form in the powder, dispersing any loose clumps and ensuring a more uniform texture. This prevents clumps from affecting subsequent use or processing. The guide unit regulates the powder's flow direction during discharge, ensuring a stable path and reducing powder residue in the weighing hopper 1, thus improving powder utilization. Simultaneously, the synergistic effect of the agitator and guide unit accelerates the discharge speed, preventing powder accumulation and stagnation in the weighing hopper 1, and improving overall work efficiency.

[0023] The rotation center lines of the transmission cover 11, the output shaft of the second motor 7, the agitator and the guide are coaxial with the axis of the through hole.

[0024] The transmission cover 11, the output shaft of the second motor 7, the agitator, and the guide are all coaxially arranged with the axis of the through hole as the rotation centerline. This structural design allows each component to maintain a high degree of concentricity and coordination during operation, ensuring that the agitator can uniformly stir the powder in the hopper 1 symmetrically with the axis of the through hole as the center during rotation, avoiding stirring dead corners caused by eccentricity, thereby more effectively breaking up powder clumps and making the material distribution more uniform. The coaxial connection between the guide and the output shaft of the second motor 7 ensures that the powder can be stably guided to the discharge port along the axis during the falling process, reducing the friction and adhesion between the material and the inner wall of the hopper 1, further reducing the risk of blockage. As a key component for power transmission, the coaxial design of the transmission cover 11 makes the chain 14 transmission smoother, reduces energy loss and noise during the transmission process, and also reduces the load on the bearings, extending the service life of each component. Ultimately, through the synergistic effect of this precise coaxial structure, the anti-blocking performance and working efficiency of the hopper 1 are significantly improved.

[0025] The agitation unit includes an agitator 21 fixed below the first sprocket 12, and the agitator 21 is radially fixed with a first agitator 22 and a second agitator 23.

[0026] The agitator is specifically structured as follows: an agitator disc 21 is fixedly connected below the first sprocket 12, and the agitator disc 21 is fixedly connected to the first agitator arm 22 and the second agitator arm 23 along the radial direction. When the first motor 6 drives the first sprocket 12 to rotate through the sprocket drive, it will synchronously drive the agitator disc 21, the first agitator arm 22, and the second agitator arm 23 to rotate together. During the rotation, the first agitator arm 22 and the second agitator arm 23 can tumble and stir the powder in the weighing hopper 1 from multiple directions and angles. The rotation of the agitator disc 21 further enhances the agitation effect on the powder, effectively breaking up any possible powder clumps, making the powder more evenly distributed in the weighing hopper 1. At the same time, this agitation effect can also prevent the powder from accumulating locally at the bottom or inner wall of the weighing hopper 1, creating favorable conditions for the subsequent guiding part to guide the powder out, reducing the blockage problem caused by accumulation, and improving the overall smoothness of material discharge.

[0027] The first stirring arm 22 and the second stirring arm 23 are arranged symmetrically.

[0028] The first stirring arm 22 and the second stirring arm 23 are symmetrically distributed around the axis of the through hole. The symmetrical structure allows the centrifugal force generated by the two stirring arms during rotation to balance each other, effectively reducing vibration and offset during the operation of the stirring part and reducing the risk of collision or friction with the inner wall of the weighing hopper 1.

[0029] The outer edges of the first stirring arm 22 and the second stirring arm 23 are fixed with scrapers, which are in contact with the inner wall of the weighing hopper 1 so as to scrape off the powder on the inner wall of the weighing hopper 1 during stirring; the scrapers are elastic scrapers.

[0030] Scrapers are fixedly connected to the outer edges of the first stirring arm 22 and the second stirring arm 23, and the scrapers are in contact with the inner wall of the weighing hopper 1. Structurally, the scrapers, as extensions of the stirring arms, fit tightly against the inner wall of the weighing hopper 1. Their shape matches the curvature of the inner wall of the weighing hopper 1 to reduce contact gaps. Furthermore, the use of wear-resistant materials reduces wear caused by long-term friction. Functionally, when the stirring arms rotate with the stirring disc 21, the scrapers slide synchronously along the inner wall of the weighing hopper 1. Through this sliding contact, the powder adhering to the inner wall of the weighing hopper 1 can be directly scraped off, preventing the powder from accumulating and forming clumps or clogging dead corners. Because the contact between the scraper and the inner wall is a smooth sliding rather than a hard collision, and the wear-resistant design of the material further reduces the frictional resistance between them, the scraping effect is ensured while reducing equipment wear. Simultaneously, the scraped powder is carried back into the stirring area by the stirring arms, improving... To improve powder utilization, the stirring arm ensures the powder in the weighing hopper 1 remains loose and flowing. The scraper is made of elastic material, and its elastic structure allows it to maintain adaptive elastic contact with the inner wall of the weighing hopper 1 as it rotates with the stirring arm. When encountering unevenness or local resistance on the inner wall, the elastic scraper can buffer the impact force through its own deformation, avoiding damage to the inner wall from hard scraping, while ensuring a tight fit without gaps, effectively scraping off the adhered powder. During the scraping process, the flexibility of the elastic material also reduces frictional resistance with the powder, lowers energy consumption, reduces powder particle breakage, and improves material flowability. In addition, the elasticity allows the scraper to maintain good scraping performance even after long-term use, extending its service life and reducing maintenance frequency due to scraper wear. Ultimately, this elastic design achieves the dual effects of high efficiency in preventing sticking to the wall and low frictional wear.

[0031] The guide section includes a guide rod 31, one end of which is connected to the output shaft of the second motor 7, and the other end extends from the transmission cover 11 along the axial direction of the weighing hopper 1 to the discharge port at the bottom of the weighing hopper 1.

[0032] The guiding section consists of a guide rod 31. One end of the guide rod 31 is connected to the output shaft of the second motor 7, and the other end extends from the transmission cover 11 along the axial direction of the weighing hopper 1 to the discharge port at the bottom of the weighing hopper 1. When the second motor 7 is started, it will drive the guide rod 31 to rotate around the axis of the weighing hopper 1. During the rotation, the guide rod 31 can guide the powder in the weighing hopper 1, so that the powder can flow more smoothly to the discharge port at the bottom of the weighing hopper 1, avoiding the powder from flowing turbulently or accumulating locally in the weighing hopper 1.

[0033] The guide rod 31 has spiral blades 32 on its outer peripheral surface near the discharge port to promote the flow of powder to the discharge port and discharge.

[0034] The guide rod 31 of the guide section is provided with a spiral blade 32 on the outer circumference near the bottom discharge port of the weighing hopper 1. The size of the spiral blade 32 matches that of the bottom discharge port of the weighing hopper 1. When the second motor 7 drives the guide rod 31 to rotate, the spiral blade 32 will rotate synchronously with the guide rod 31. Utilizing the propulsive action of the spiral structure, an axial thrust is generated on the powder near the discharge port, forcibly pushing the powder along the rotation trajectory of the spiral blade 32 toward the discharge port. This active pushing method can effectively break the static balance that may be formed near the discharge port of the powder, avoiding bridging and blockage caused by friction or adhesion between powders. At the same time, the rotation of the spiral blade 32 can also stir and loosen the surrounding powder, allowing the powder that may have clumped to be broken up and smoothly enter the discharge port, further promoting the rapid and uniform discharge of the powder, greatly improving the discharge efficiency and smoothness, and ensuring that the weighing hopper 1 maintains stable operation during the weighing and discharge process.

[0035] The present invention relates to a powder weighing hopper with an anti-clogging structure. During use, powder enters the weighing hopper 1 from the feed hopper 5. If it is necessary to separately stir and disperse the powder or clean the residue on the inner wall, the first motor 6 can be started independently, driving the stirring disc 21, the first stirring arm 22, the second stirring arm 23, and the elastic scraper of the stirring part to rotate, thereby achieving uniform stirring, breaking up lumps, and scraping off residue from the inner wall. If it is necessary to separately guide the flow of powder or unclog the discharge port, the second motor 7 can be started independently, driving the guide rod 31 with spiral blades 32 to rotate, promoting the flow of powder towards the discharge port and pushing it out. Alternatively, both motors can be started simultaneously, allowing the stirring part and the guide part to work together to achieve uniform stirring, anti-clogging, and efficient discharge. By starting them separately or simultaneously, the usage requirements under different working conditions can be met.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
