DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the technical methods, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] Embodiment 1

[0020] Such as Figure 1 、 Figure 2 And Figure 4An intelligent and precise feeder capable of real-time weighing is shown, including a lower cover 1. The upper surface of the lower cover 1 is detachably connected to an upper cover 2 by bolts. The lower surface of the lower cover 1 is fixedly connected to an outer shell 3. The lower surface of the outer shell 3 is fixedly connected to a weighing plate 4. A plurality of weighing sensors 5 are evenly distributed on the upper surface of the weighing plate 4 along the circumferential direction. A feed cylinder 6 is arranged inside the outer shell 3 on the lower surface of the lower cover 1. A transfer flange ring 7 is fixedly connected to the circumferential outer wall of the lower end of the feed cylinder 6. A plurality of support columns 8 corresponding in number and position are fixedly connected to the lower surface of the transfer flange ring 7. One side of the support column 8 away from the transfer flange ring 7 is connected to the weighing sensor 5. An installation groove 9 is formed in the middle of the weighing plate 4. A feed pipe 10 communicating with the feed cylinder 6 is fixedly connected inside the installation groove 9. A control box 11 is fixedly installed on the circumferential outer wall of the feed pipe 10.

[0021] Furthermore, the lower cover 1 is communicated with the feed cylinder 6, which facilitates the feed to fall into the feed cylinder 6.

[0022] Furthermore, an electromagnetic valve for controlling the feed switch is installed inside the feed pipe 10.

[0023] Furthermore, the control box 11 includes a display screen 111, control buttons 112 and a built-in control computer.

[0024] Furthermore, both the electromagnetic valve and the weighing sensor 5 are electrically connected to the control box 11.

[0025] Embodiment 2

[0026] As Figure 3 An intelligent and precise feeder capable of real-time weighing is shown. One end of the circumferential outer wall of the feed cylinder 6 away from the transfer flange ring 7 is fixedly connected to an installation ring 12. A plurality of brackets 13 are fixedly connected between the installation ring 12 and the transfer flange ring 7. A rubber ball 131 is slidably connected to the circumferential outer wall of the bracket 13. A spring 132 is sleeved on the circumferential outer wall of the bracket 13 at one end of the rubber ball 131 close to the transfer flange ring 7. A limit block 133 is fixedly connected to the bracket 13 at one end of the spring 132 away from the rubber ball 131. Both ends of the spring 132 are fixedly connected to the rubber ball 131 and the limit block 133 respectively.

[0027] During specific operation, when the feed in the barrel 6 gradually increases, the center of gravity of the barrel 6 also rises. When the center of gravity rises to a certain height, the entire barrel 6 will shake due to uneven feed distribution and other external influencing factors, which will affect the force on the load cell 5 and further affect the weighing accuracy. When the center of the barrel 6 shifts, it will first come into contact with the rubber ball 131 and cause it to move. During the movement of the rubber ball 131, the spring 132 is compressed and deformed. At this time, the spring 132 and the rubber ball 131 play a buffering role for the barrel 6 to prevent further shift and improve the stability of the barrel 6.

[0028] Working principle:

[0029] During use, the operator removes the bolts between the upper cover 2 and the lower cover 3 to separate the upper cover 2 from the lower cover 3. Then, the upper cover 2 and the lower cover 3 are sleeved outside the feeding line, and the upper cover 2 and the lower cover 3 are fixed with bolts and hoisted on the feeding line. The feeding line transports the feed to the barrel 6 through the lower cover 2. The load cell 5 will detect the weight change until the barrel 6 is full of feed. At this time, the load cell 5 will detect a stable value, which is the weight a. By pressing the control button 11, the solenoid valve in the discharge pipe 10 is opened to start discharging. The load cell 5 will detect the weight change again until the discharging is completed. At this time, the load cell 5 will detect another stable value, which is the weight b. Subtracting the value of b from the value of a gives the actual weight m of this discharging (m = a - b). This value can be displayed in real time on the display screen 111, thus realizing accurate discharging. At the same time, the operator can also view the real-time discharging weight according to the real-time discharging weight on the display screen 111 and use the control button 112 to intervene in the discharging action and stop or continue the discharging action at any time.
