Description

Technical Field

[0001] The utility model relates to the technical field of powder material conveying, in particular to a high-precision powder material belt conveying feeding device. Background Art

[0002] Traditional equipment for conveying and handling powder materials often faces numerous challenges. First, powder materials are prone to generating dust during transportation. This dust not only pollutes the production environment but can also adversely affect equipment, products, and the health of operators. Dust accumulation can also cause equipment failures, reduce production efficiency, and even affect product quality and purity. This problem is particularly prominent in precision manufacturing.

[0003] Secondly, traditional conveyor feeding devices lack accuracy and flexibility. Due to the lack of precise control systems and adjustment mechanisms, operators struggle to precisely control the feed rate, resulting in an unstable feeding process and difficulty meeting the stringent weighing accuracy requirements of precision production. Furthermore, manual adjustment is not only inefficient but also prone to errors, further impacting production efficiency and product quality.

[0004] Furthermore, material residue is a major challenge for traditional conveying and feeding systems. Due to design flaws or improper operation, materials can easily accumulate or remain on the equipment during conveying. This not only reduces conveying efficiency but also may increase equipment wear and shorten its service life. Furthermore, material residue can affect the stability of subsequent production processes, increasing production costs and risks. Utility Model Content

[0005] The utility model relates to a high-precision powder belt conveying and feeding device, which is a new type of conveying and feeding device that can simultaneously solve the problems of dust suppression, feeding accuracy, operation flexibility and safety.

[0022] Secondly, the precise control and adjustment mechanism of the conveying mechanism significantly improves feeding accuracy and flexibility. The drive motor drives the belt through a chain drive system, ensuring continuous and stable material transportation.

[0033] Example 1: Please refer to Figures 1 to 2 :

[0034] The utility model proposes a high-precision powder belt conveying feeding device, comprising: a trough body 1, the trough body 1 has a closed conveying space;

[0035] The tank cover 2 is sealed and connected to the tank body 1 to form a dust suppression structure;

[0036] The feed port 6 is provided at one end of the tank body 1 and is used to receive powder materials;

[0037] The discharge port 18 is provided at the other end of the tank body 1 and is used to discharge the powder material to be weighed;

[0038] The conveying mechanism includes a belt 3, a driving wheel shaft 15, a driven wheel shaft 10, a pulley 14, a chain 19 and a drive motor 23. The drive motor 23 is connected to the driving wheel shaft 15 through the chain 19. The driving wheel shaft 15 and the driven wheel shaft 10 are respectively equipped with pulleys 14. The belt 3 is wrapped around the two pulleys 14 to form a closed loop conveying path;

[0039] Manually adjust the gate 5, which is installed above the tank body 1 and is used to adjust the amount of powder material passing through;

[0040] The frequency conversion control unit is electrically connected to the drive motor 23 and is used to control the speed of the drive motor 23 according to the preset feeding amount to achieve high-precision feeding;

[0041] The scraper 16 is installed at the discharge port 18. By adjusting its position, it ensures close contact with the belt 3 to prevent material residue.

[0042] The protective cover 20 is covered around the driving mechanism to protect the safety of the operator and reduce dust leakage.

[0043] Among them, sealing gaskets are provided at the connections between the tank body 1 and the tank cover 2, and between the tank body 1 and the front side plate 17, the rear side plate 13, and the left and right side plates 7.

[0044] The conveying mechanism further includes a belt support plate 4, which is arranged below the belt 3 and is used to support the belt 3 and guide it to run smoothly.

[0045] The manually adjustable gate plate 5 can be moved up and down by an adjusting mechanism to adjust the amount of powder material passing through.

[0046] It also includes a tensioning screw 9, which is arranged on the driven wheel shaft 10 and is used to adjust the tension of the belt to ensure smooth operation of the belt 3.

[0047] The second embodiment, based on the first embodiment, further comprises a detection proximity switch 11 for detecting whether there is abnormality in the rotation of the pulley shaft.

[0048] The working principle of this embodiment is as follows:

[0049] After the device is started, powder materials are fed into the tank body 1 through the feed port 6. The sealed connection between the tank body 1 and the tank cover 2, as well as the sealing gaskets at each connection, together form a closed conveying space, effectively suppressing the dust generated during the material conveying process, protecting the production environment, and reducing the impact of dust on the health of operators.

[0050] As the drive motor 23 is started, the motor is connected to the driving shaft 15 through the chain 19, driving the pulley 14 on the driving shaft 15 to rotate. Since the driving shaft 15 and the driven shaft 10 are respectively equipped with pulleys 14 and connected by the belt 3 to form a closed-loop conveying path, the driven shaft 10 will also rotate, thereby driving the belt 3 to circulate in the tank body 1.

[0051] As belt 3 moves, it conveys powdered material from feed port 6 to discharge port 18. To precisely control the feed rate, the device is equipped with a manually adjustable gate 5. Operators can adjust the amount of powdered material passing through by moving the gate 5 up and down, depending on production needs.

[0052] To improve feeding accuracy, the device also incorporates a frequency conversion control unit. This control unit is electrically connected to the drive motor 23 and automatically adjusts the motor's speed based on the preset feeding amount. A proximity switch 11 detects any anomalies in the pulley shaft's rotation.

[0053] The scraper 16 plays a key role in conveying the material to the discharge port 18. By adjusting the position of the scraper 16, it can be ensured to fit tightly against the belt 3, effectively preventing material from remaining under the belt. This allows the weighed powder material to be smoothly discharged from the discharge port 18 and enter the subsequent production process.

[0054] In addition, in order to ensure the safety of operators and reduce dust leakage, a protective cover 20 is provided around the driving mechanism of the device.

[0055] In this article, there are several points to note:
