[0030] A resetting elastic member 41 is disposed at the top of the storage barrel 4 . The resetting elastic member 41 is fixedly connected to the control rod 31 to drive the control rod 31 to reset.

[0031] The present invention discloses a vibrating feeding device for powders, wherein a frame 1 is fixed on a desktop as a supporting structure of the entire device, to ensure the stability and position fixation of the device, and to avoid inaccurate control caused by shaking; a vibration component 2 is installed on the frame 1, to provide power for powder feeding, and the powder material can be effectively loosened and conveyed in a storage barrel 4 through vibration, thereby improving feeding efficiency, avoiding powder blockage, affecting feeding continuity, and avoiding feeding speed fluctuations caused by unstable position of a control rod 31; the storage barrel 4 is used for containing powder material, and is the main container for powder feeding, and a control component 3 inside the control component 3 is used for controlling the feeding speed of the powder, so as to achieve precise adjustment of the feeding amount; when in use, the control rod 31 is longitudinally slidably arranged in the storage barrel 4, and its bottom end is detachably connected to the outlet of the storage barrel 4, and its top end extends out of the storage barrel 4 and is sealed and slidably connected to the top of the storage barrel 4, and the control rod 31 is used for controlling the feeding speed of the powder, so as to achieve precise adjustment of the feeding amount; The control rod 31 moves up and down in the storage barrel 4, which is convenient for controlling the opening and closing of the powder outlet and the powder feeding speed, and at the same time can maintain the sealing of the top of the storage barrel 4; the elevator 32 is installed on the side wall of the vibration component 2 and is transmission-connected to the top of the control rod 31. Through the drive of the elevator 32, the control rod 31 can move up and down in the storage barrel 4, thereby changing the opening size of the bottom end of the storage barrel 4, thereby controlling the powder feeding speed and achieving accurate control of the feeding amount. At the same time, the elevator 32 can position the control rod 31 at a set position to maintain a stable speed of powder feeding; the reset elastic member 41 is fixedly connected to the control rod 31. When the elevator 32 stops driving or reverses driving, the reset elastic member 41 can drive the control rod 31 to reset, that is, return to the initial position or a set position, avoiding the feeding speed fluctuation caused by the unstable position of the control rod 31, which helps to maintain the stability and controllability of the feeding speed. The invention has a compact structure and is easy to use. It can conveniently control the opening and closing of powder material feeding and the stable feeding of powder material by combining vibration and lifting control, thereby realizing accurate control of powder feeding speed and improving feeding stability and accuracy.

[0032] In one embodiment of the present application, the frame 1 includes a base plate 11, and the vibration component 2 is installed below the base plate 11 for easy installation; the four corners of the base plate 11 are supported by four liftable support columns 12, so that the vibration component 2 and the storage barrel 4 are suspended on the table, which is convenient for receiving the falling powder material.

[0033] In one embodiment of the present application, a support foot 13 is provided at the bottom end of the support column 12 to facilitate expansion of the support area and improve stability. At the same time, the rack 1 can be fixed on the desktop through the support foot 13, further improving stability.

[0034] Further optimization scheme, the bottom end of the storage barrel 4 is provided with a discharge port 42, and the bottom end of the control rod 31 is provided with a conical blocking block 33, the top diameter of the blocking block 33 is larger than the inner diameter of the discharge port 42, and the bottom diameter of the blocking block 33 is smaller than the inner diameter of the discharge port 42. The conical design of the blocking block 33 at the bottom end of the control rod 31 enables it to effectively block or open the discharge port 42 during the lifting process, and at the same time, the powder falls from the gap between the blocking block 33 and the discharge port 42 assembly, thereby controlling the opening and closing of the powder feeding and the feeding speed. The design of the conical blocking block 33 makes the blocking block 33 more closely cooperate with the discharge port 42 during the lifting process, avoiding the leakage of powder and improving the accuracy of feeding.

[0035] Further optimization scheme, the top of the control rod 31 is fixedly connected with a transmission rod 34, and the top of the transmission rod 34 is provided with a force block 35, the force block 35 is slidably connected to the side wall of the vibration component 2, and the output shaft end of the elevator 32 is transmission-connected with the force block 35. The action of the elevator 32 can be transmitted to the transmission rod 34 through the force block 35, thereby controlling the lifting and lowering of the control rod 31, realizing the indirect transmission between the elevator 32 and the control rod 31, thereby driving the lifting and lowering of the control rod 31, controlling the opening and closing of the discharge port 42 and the material discharge speed, making the lifting and lowering of the control rod 31 more stable and reliable; at the same time, after the elevator 32 moves into place, it can effectively maintain the position of the control rod 31, thereby maintaining the stability of the material discharge speed of the discharge port 42.

[0036] Further optimization scheme, a force block 36 is arranged below the force block 35, the force block 36 surrounds the transmission rod 34 and is arranged with a gap with the transmission rod 34, and the force block 36 is fixedly connected to the output end of the elevator 32. The force block 36 is designed as a fork-shaped structure, which is arranged around the transmission rod 34, and its top end contacts the lower end of the force block 35. The action of the elevator 32 can be directly transmitted to the force block 35 through the force block 36, and then the lifting and lowering of the control rod 31 can be controlled, so that the output force of the elevator 32 can be more directly and effectively transmitted to the force block 35, improving the efficiency and accuracy of the transmission; at the same time, the control rod 31 can be maintained at a set position through the support of the force block 36 on the force block 35, which is convenient for the stable speed of powder feeding.

[0037] In a further optimized solution, the top of the storage barrel 4 is threadedly connected with a mounting seat 43, which is threadedly connected to the mounting hole 23 at the bottom of the vibration component 2, and the contact surface between the control rod 31 and the transmission rod 34 is located in the inner cavity of the mounting seat 43. The mounting seat 43 plays a role of fixing and supporting, and the storage barrel 4 is installed below the vibration component 2, so that the connection between the storage barrel 4 and the control component 3 is more firm and stable, avoiding looseness or damage caused by vibration, and facilitating later inspection and maintenance.

[0038] Further optimized solution, the transmission rod 34 is slidably connected with a sliding sleeve 37, and the reset elastic member 41 is arranged between the sliding sleeve 37 and the top of the mounting hole 23. When the control rod 31 closes the discharge port 42, the reset elastic member 41 is in a compressed state, and when the elevator 32 rises, the reset elastic member 41 is further compressed; when the elevator 32 stops but does not move in the reverse direction, the force block 36 supports the force block 35, and the reset elastic member 41 does not move; and when the output end of the elevator 32 drives the force block 36 to descend, the force block 35 loses support, and the reset elastic member 41 applies a reverse force to the sliding sleeve 37, which can drive the sliding sleeve 37 and the control rod 31 to reset, thereby improving the automation and stability of the device.

[0039] In a further optimized solution, a positioning plate 44 is provided in the mounting seat 43, the control rod 31 passes through the positioning plate 44 and is fixedly connected to the connecting plate 38, the transmission rod 34 is fixedly connected to the top of the positioning plate 44, and the sliding sleeve 37 abuts against the top of the connecting plate 38. The positioning plate 44 plays a supporting and positioning role. When the control rod 31 is not subjected to force, the reset elastic member 41 pushes the sliding sleeve 37 to press the connecting plate 38 onto the positioning plate 44, so that the control rod 31 can push the blocking block 33 to block the discharge port 42, and can also prevent the blocking block 33 from being stuck due to excessive downward pressure of the control rod 31, making the control rod 31 more stable and reliable, and avoiding loosening or damage caused by vibration.

[0040] In a further optimized solution, a feed pipe 45 is tiltedly arranged on the side wall of the storage barrel 4, the feed pipe 45 is connected to the inner cavity of the storage barrel 4, and a cover 46 is threadedly installed on one end of the feed pipe 45 away from the storage barrel 4. When in use, the cover 46 on the feed pipe 45 can be unscrewed, and powder material can be added into the storage barrel 4 through the feed pipe 45, making the addition of powder material more convenient and quick. After the powder filling is completed, the cover 46 is tightened to avoid powder leakage, and it can also effectively prevent external impurities from entering the storage barrel 4 to affect the purity of the powder material.

[0041] According to a further optimized solution, the vibration assembly 2 includes a vibration housing 21 fixed to the frame 1, a vibration motor 22 is arranged in the vibration housing 21, a force bearing block 35 is slidably connected to the side wall of the vibration housing 21, and a storage barrel 4 is installed at the bottom end of the vibration housing 21. When the vibration motor 22 is running, it can drive the vibration housing 21 to vibrate regularly, and at the same time drive the control assembly 3 and the storage barrel 4 installed on the vibration housing 21 to vibrate together, so that the device can promote the flow and discharge of powder through vibration, avoid the accumulation or blockage of powder in the storage barrel 4, and improve the efficiency and accuracy of discharge.

[0042] In one embodiment of the present application, the top of the vibration housing 21 is open, and the vibration motor 22 is installed from the open position at the top of the vibration housing 21, which makes loading and unloading more convenient.

[0043] In one embodiment of the present application, an assembly hole 14 compatible with the vibration motor 22 is formed through the substrate 11, which facilitates the loading and unloading of the vibration motor 22 without disassembling the vibration shell 21, and facilitates the connection of the power line and control line of the vibration motor 22.

[0044] In one embodiment of the present application, a non-through section of the substrate 11 is provided with a clearance groove adapted to the vibration shell 21, and the vibration shell 21 is installed in the clearance groove through a plurality of spring shock absorbers, thereby reducing the vibration frequency transmitted to the frame 1 by the vibration shell 21 and improving stability; the spring shock absorbers are commercially available products, which are conventional technical means and will not be described in detail here.

[0045] Further optimization scheme, the side wall of the vibration shell 21 is provided with a longitudinal guide groove 24, the guide groove 24 is arranged corresponding to the storage barrel 4, the force block 35 is slidably connected in the guide groove 24, and the force block 36 extends into the guide groove 24 and is slidably connected with the guide groove 24. The force block 35 and the force block 36 slide smoothly in the guide groove 24, so that the sliding of the force block 35 and the force block 36 is more stable and reliable, avoiding transmission failure or damage caused by poor sliding; at the same time, the guide groove 24 also plays a role of limiting, ensuring the position accuracy of the force block 35 and the force block 36 during the sliding process.
