Description

Technical Field

[0001] This utility model relates to the field of powder feeding technology, specifically a powder feeding machine. Background Technology

[0002] In many industries such as chemicals, food, and building materials, powder conveying is a crucial step in the production process. However, existing powder feeders suffer from numerous problems in practical applications.

[0003] Chinese Patent: Publication No.: CN222159118U, Application Title: A Powder Feeding Mechanism, comprising a servo motor, a material box, a grooved roller, a feeding trough, and a baffle plate. The material box is fixedly installed above the feeding trough and communicates with it. The grooved roller is rotatably installed inside the feeding trough. The servo motor is located at one end of the grooved roller and connected to it. The baffle plate is slidably connected to the lower end of the feeding trough. This invention, by setting a material box on the feeding trough and a baffle plate below it, can prevent powder from splashing everywhere, reducing labor intensity; by driving the grooved roller to rotate with a servo motor, the feeding accuracy can be precisely controlled by controlling the speed of the servo motor, thus improving product quality.

[0004] However, existing powder feeders lack weighing functionality in actual use, which prevents them from effectively conveying weight and meeting actual usage needs, thus reducing their conveying efficiency. To address this, we propose a new powder feeder. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Preferably, support legs are fixedly connected to both the left and right sides of the bottom of the base plate, and anti-slip pads are provided on the bottom of the support legs.

[0014] 1. This utility model uses a motor to drive a threaded rod to rotate, causing the threaded sleeve to move along the threaded rod, which in turn moves the lifting plate and sealing plate up and down. It can precisely control the opening and closing degree of the discharge hole, thereby accurately controlling the amount of powder conveyed and meeting the precise powder usage requirements of different production needs. The weighing device can weigh the powder on the mounting plate in real time.

Example 1

[0024] Please see Figures 1-5The following technical solution is provided, specifically disclosing: a powder feeder, including a base plate 1, a conveying box 3 fixedly connected to the top of the base plate 1 around the perimeter by a first support rod 2, a motor 5 fixedly installed on the left side of the top of the conveying box 3 by bolts, a threaded rod 21 fixedly connected to the output end of the motor 5, a threaded sleeve 20 threadedly connected to the surface of the threaded rod 21, a lifting plate 18 fixedly connected to one side of the threaded sleeve 20, a sealing plate 17 fixedly connected to the bottom of the lifting plate 18, a weighing device 15 fixedly connected to the top of the base plate 1 by a second support rod 14, an mounting plate 13 fixedly connected to the top of the weighing device 15, a second electric telescopic rod 12 fixedly installed on the outer side of the mounting plate 13 by bolts, and a baffle 23 fixedly connected to the output end of the second electric telescopic rod 12 by a push plate 24;

[0025] In actual use, the motor 5 drives the threaded rod 21 to rotate, causing the threaded sleeve 20 to move along the threaded rod 21, which in turn drives the lifting plate 18 and the sealing plate 17 to move up and down. This allows for precise control of the opening and closing of the discharge hole 22, thereby precisely controlling the amount of powder conveyed and meeting the precise powder usage requirements of different production needs. The weighing device 15 can weigh the powder on the mounting plate 13 in real time. In conjunction with the second electric telescopic rod 12 and the baffle 23, when the set weight is reached, the second electric telescopic rod 12 pushes the baffle 23 to close the discharge hole 22, achieving precise feeding and improving production accuracy and product quality. Example 2

[0026] Please see Figure 1 and Figure 2 The following technical solution is provided, specifically disclosed: A battery box 8 is fixedly connected to one side of the material conveying box 3 by bolts, and a storage battery 9 is fixedly connected to the inner cavity of the battery box 8 by bolts. A charging port 10 is opened at the middle of one side of the battery box 8, and the output end of the charging port 10 is unidirectionally electrically connected to the input end of the storage battery 9. A movable door 11 is movably connected to one side of the material conveying box 3 by a hinge. A discharge hole 22 is opened at the middle of the bottom of the material conveying box 3. A first electric telescopic rod 4 is fixedly installed on one side of the material conveying box 3 by bolts. A cleaning plate 19 is fixedly connected to the output end of the first electric telescopic rod 4. A feed pipe 6 is fixedly connected to the middle of the top of the material conveying box 3. A guide plate 16 is fixedly connected to the inner side of the first support rod 2. A PLC controller 7 is fixedly installed on the top of the outer side of the material conveying box 3 by bolts. The output end of the PLC controller 7 is unidirectionally electrically connected to the input end of the motor 5, the second electric telescopic rod 12, and the first electric telescopic rod 4.

[0027] In actual use, the movable door 11, which is connected to one side of the conveying box 3 via a hinge, allows operators to easily enter the interior of the conveying box 3 for equipment inspection, maintenance, and cleaning, thus improving the convenience of equipment maintenance. The first electric telescopic rod 4 moves the cleaning plate 19 within the conveying box 3, which can promptly clean the powder adhering to the inner wall of the conveying box 3, preventing powder accumulation from affecting the normal operation of the feeder and extending the service life of the equipment.

[0028] In use: Charge the battery 9 through charging port 10 to ensure emergency power is available when needed. Check that the motor 5, the first electric telescopic rod 4, the second electric telescopic rod 12, and other equipment are operating normally and that all connections are secure. Set the required powder conveying parameters on the PLC controller 7. The powder enters the conveying box 3 through the feed pipe 6. The guide plate 16 guides the powder to flow towards the discharge hole 22. Start the motor 5, which drives the threaded rod 21 to rotate. The threaded sleeve 20 moves downward along the threaded rod 21, causing the lifting plate 18 and the sealing plate 17 to move downward, opening the discharge hole 22. The powder falls onto the mounting plate 13 through the discharge hole 22.

[0029] Weighing device 15 weighs the powder on mounting plate 13 in real time. When the set weight is reached, PLC controller 7 controls the second electric telescopic rod 12 to start. The second electric telescopic rod 12 pushes the baffle 23 through push plate 24 to close the discharge hole 22 and stop feeding. After feeding is completed, the first electric telescopic rod 4 is started. The first electric telescopic rod 4 drives the cleaning plate 19 to move inside the conveying box 3 to clean the powder adhering to the inner wall of the conveying box 3. The motor 5, the first electric telescopic rod 4 and the second electric telescopic rod 12 are turned off to stop the operation of the feeder.

[0030] Record weighing data, check for any abnormalities in the equipment, and perform timely repairs and maintenance if necessary.
