DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0024] like Figure 1-2 As shown, the embodiment of the present application discloses an automatic weighing and replenishing device for trace raw materials of impregnating agent for glass fiber, including a bracket 10, on which a raw material bin 20, a weighing platform 30 and a weighing bin 31 are arranged. The raw material bin 20 is used to store raw materials. When needed, the raw materials are placed in the weighing bin 31, and then weighed by the weighing platform 30 to accurately control the amount. Finally, the raw materials are released from the weighing bin 31, thereby achieving the purpose of accurate weighing and automatic replenishment, greatly improving work efficiency and saving labor costs.

[0025] In the specific setting, a raw material bin 20 is set on the top of the bracket 10. The raw material bin 20 is funnel-shaped as a whole and is used to store raw materials. A first discharge port 21 is set at the bottom of the raw material bin 20, and a raw material control valve 22 is set in the first discharge port 21 to accurately control the release amount of the raw material. A cover plate 23 is set at the bin opening of the raw material bin 20 to protect the raw materials and prevent dust and other debris from entering the raw material bin 20. A motor 24 is fixedly set on the cover plate 23, and the output shaft of the motor 24 passes through the cover plate 23 downward and is connected to a rotating shaft 25 at the end. The axis of the rotating shaft 25 is set to deviate from the center line of the raw material bin 20. A plurality of stirring blades 26 are radially arranged at the lower end of the rotating shaft 25. The motor 24 is set by the program to automatically run in stages after the weighing and preparation begins, so that the stirring blades 26 stir the raw materials in the raw material bin 20 in stages to prevent the raw materials from settling.

[0026] The weighing platform 30 is arranged in the bracket 10, and a support frame 34 is arranged on the weighing platform 30. The weighing bin 31 is mounted on the support frame 34. The weight of the weighing bin 31 can be weighed by the weighing platform 30, so as to weigh the raw material dosage. The weighing bin 31 is funnel-shaped as a whole, and its upper opening is located below the first discharge port 21 of the raw material bin 20 to receive the raw material falling from the first discharge port 21 of the raw material bin 20. A second discharge port 32 is arranged at the bottom of the weighing bin 31, and a discharge control valve 33 is arranged in the second discharge port 32. The discharge control valve 33 is used to control the release of the raw material in the weighing bin 31. There is an opening 35 in the middle of the weighing platform 30, and a discharge pipe 36 extending downward and passing through the opening 35 is arranged at the second discharge port 32, so that the raw material can be discharged directly vertically to avoid the bending of the pipeline causing the raw material to be partially intercepted and affect the accurate dosage.

[0027] Further, a flushing assembly 40 is provided at the top of the support frame 34 at the port of the weighing bin 31. The flushing assembly 40 includes a flushing ball 41 provided at the top of the support frame 34, two flushing balls 41 are symmetrically provided along the center of the weighing bin 31, and the flushing balls 41 are connected to an external water source through a water pipe 42. After the raw materials are weighed and released, the flushing balls 41 can be used to flush the weighing bin 31 360 degrees to keep the weighing bin 31 clean.

[0028] The operating principle of the automatic weighing and replenishing device for trace raw materials of impregnating agent for glass fiber in this embodiment is: the raw materials are stored in the raw material bin 20. When the raw materials need to be prepared, the raw material control valve 22 is controlled to open to release the raw materials into the weighing bin 31 below. The weighing platform 30 performs real-time weighing. After reaching the setting, the raw material control valve 22 is immediately controlled to close, and then the discharge control valve 33 is opened to release the raw materials from the second discharge port 32 and the discharge pipe 36, so as to realize accurate weighing and automatic replenishment.
