The weighing hopper gate opening and closing cylinder constitutes the weighing hopper gate power mechanism.

[0007] Preferably, the discharge port of the feeding hopper is rectangular, and the hopper door is rectangular. A hopper door flange is fixed on the lower side, left side and right side of the hopper door, and the hopper door flange partially surrounds the outer wall of the feeding hopper corresponding to the discharge port position.

[0008] Preferably, when the discharge port of the feeding hopper is closed by the weighing hopper gate, the flange of the weighing hopper gate forms an acute angle with the outer wall of the feeding hopper at the corresponding discharge port position.

[0009] This utility model has a simple structure and a good sealing effect between the weighing hopper gate and the discharge port of the feeding hopper, which can effectively prevent powder from overflowing from the discharge port when the weighing hopper gate is closed, thus improving the weighing accuracy.

[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] A sealed feeding hopper device, such as Figure 1 and Figure 2 As shown, it includes a feeding hopper 1, a weighing sensor 2, a sealing strip 3, a hopper door seat 4, and a hopper door 5; Several weighing sensors 2 are fixed on the upper part of the outer wall of the feeding hopper 1. An inclined discharge port is provided at the lower end of the feeding hopper 1. A sealing strip 3 is fixed on the feeding hopper 1 at the corresponding discharge port position. A hopper door seat 4 is fixed on the lower part of the outer wall of the feeding hopper 1. A hopper door 5 is hinged on the hopper door seat 4. The hopper door 5 is driven by a power mechanism to close or open the discharge port of the feeding hopper 1. A weighing hopper gate flange 6 is fixed on the side of the weighing hopper gate 5. When the weighing hopper gate 5 closes the discharge port of the feeding hopper 1, the weighing hopper gate 5 squeezes the bottom surface of the sealing strip 3. The weighing hopper gate flange 6 fully or partially surrounds the outer wall of the feeding hopper 1 corresponding to the discharge port position, and the weighing hopper gate flange 6 squeezes the side of the sealing strip 3.

[0014] The sealing strip 3 has a U-shaped cross-section, and the feeding hopper 1 corresponding to the discharge port position is embedded in the U-shaped groove of the sealing strip 3.

[0015] It also includes a weighing hopper gate opening and closing cylinder 7, the cylinder seat of the weighing hopper gate opening and closing cylinder 7 is hinged to the outer wall of the unloading weighing hopper 1, and the piston rod of the weighing hopper gate opening and closing cylinder 7 is hinged to the weighing hopper gate 5.

[0016] The discharge port of the feeding hopper 1 is rectangular, and the hopper gate 5 is rectangular. A hopper gate flange 6 is fixed on the lower side, left side and right side of the hopper gate 5. The hopper gate flange 6 partially surrounds the outer wall of the feeding hopper 1 corresponding to the discharge port position.

[0017] When the weighing gate 5 closes the discharge port of the feeding hopper 1, the weighing gate flange 6 forms an acute angle with the outer wall of the feeding hopper 1 at the corresponding discharge port position.

[0018] In use, the piston rod of the weighing hopper gate opening and closing cylinder 7 extends and retracts, driving the weighing hopper gate 5 to open and close, thus closing or opening the discharge port of the feeding hopper 1. When the weighing hopper gate 5 closes the discharge port of the feeding hopper 1, the weighing hopper gate 5 presses against the bottom surface of the sealing strip 3, and the weighing hopper gate flange 6 presses against the side surface of the sealing strip 3, enhancing the sealing effect between the weighing hopper gate 5 and the discharge port of the feeding hopper 1. This effectively prevents powder from overflowing from the discharge port when the weighing hopper gate 5 is closed, thereby improving the weighing accuracy of the weighing sensor 2.

[0019] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
