Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a high-precision metering and feeding device for the production of chemical reagents.

[0026] Reference Figure 1-5 A high-precision metering and feeding device for the production of chemical reagents includes a frame 101. Support seats 102 are fixedly installed on the inner walls of both sides of the frame 101. A weighing device 103 is installed on the top of the support seats 102. A fixing plate 104 is installed on the top of the weighing device 103. A weighing box 105 is fixedly installed between the two fixing plates 104. A discharge hole 106 is opened on the bottom inner wall of the weighing box 105. A feeding pipe 107 is installed at the bottom of the weighing box 105. A horizontal plate 201 is fixedly installed on the top of the weighing box 105. A rotating pipe 203 is rotatably installed on the horizontal plate 201. A spiral pusher plate 204 is installed on the rotating pipe 203. Two rotating shafts 401 are rotatably installed on the front and rear inner walls of the feeding pipe 107. A baffle 402 is fixedly installed on the rotating shaft 401 and is adapted to the discharge hole 106.

[0027] In this embodiment, a rotating hole 202 is provided at the top of the horizontal plate 201, and a rotating tube 203 is installed in the corresponding rotating hole 202. A drive motor 302 is fixedly installed at the top of the horizontal plate 201. A transmission mechanism is provided between the drive motor 302 and the rotating tube 203. The transmission mechanism includes a drive gear 303 and a driven gear 301. The drive gear 303 is fixedly installed on the output shaft of the drive motor 302, and the driven gear 301 is fixedly installed on the rotating tube 203. The drive gear 303 meshes with the driven bevel gear. This structural design enables the power of the drive motor 302 to be transmitted to the rotating tube 203 stably and efficiently, ensuring that the spiral pusher plate 204 rotates at a uniform speed during rotation, thereby continuously and stably pushing the raw material to the discharge hole 106, further improving the effect of preventing raw material blockage and the stability of feeding.

[0028] In this embodiment, the top of the baffle 402 has a rectangular hole 403 on one side, and the rotating shaft 401 passes through the rectangular hole 403. The bottom of the weighing box 105 has a groove 601, which is located above the rectangular hole 403. A rack seat 602 is slidably installed in the groove 601, and the rack seat 602 passes through the corresponding rectangular hole 403. A rotating gear 603 is fixedly installed on the rotating shaft 401, and the rack seat 602 meshes with the corresponding rotating gear 603. Through the meshing transmission between the rack seat 602 and the rotating gear 603, the linear motion of the push rod motor 501 is converted into the rotation of the baffle 402, realizing the precise opening and closing of the feeding hole 106. The structure is simple and reliable, and it is easy to control the rotation angle of the baffle 402, thereby accurately controlling the feeding speed and feeding amount.

[0029] In this embodiment, a connecting rod 503 is movably installed inside the rotating tube 203.

[0031] In this embodiment, a controller is installed on the front side of the frame 101, and the weighing device, drive motor 302, and push rod motor 501 are all electrically connected to the controller. As the control center of the entire device, the controller can receive data from the weighing device in real time and accurately control the start-stop and operating parameters of the drive motor 302 and push rod motor 501 according to a preset program, realizing automated and intelligent control of the feeding process, which greatly improves the feeding accuracy and production efficiency.

[0032] In this invention, when the raw materials for chemical reagent production are conveyed to the weighing box 105, the weighing device can weigh the raw materials in the weighing box 105. Conveying stops when the weight of the raw materials reaches a set value, achieving high-precision control of the amount of raw materials to be added. By controlling the start of the push rod motor 501, the push rod motor 501 can move the drive plate and connecting rod 503 upwards. The connecting rod 503 can move the drive rod 504 upwards. The drive rod 504, through the vertical rod 505, moves the rack seat 602 upwards. The rack seat 602 can then rotate the rotating gear 603. The rotating gear 603 rotates... Shaft 401 can drive baffle 402 to rotate, and the two baffles 402 rotate in opposite directions, which can open the feed port, so that the raw material in the weighing box 105 can be fed through the feeding pipe 107.

The rotating tube 203 can drive the spiral pusher plate 204 to rotate. The rotation of the spiral pusher plate 204 can convey the raw material to the feed hole 106, avoiding the blockage of the raw material.
