Moreover, there is a lack of a reminder device. When the amount of material entering does not meet expectations and there is no reminder, the amount of each unloading will deviate and cannot be detected, affecting material processing. Utility Model Content

When the pressure sensor is subjected to a certain pressure, the forward and reverse switch controls the motor shaft to reverse, and the first stop switch and the second stop switch are started to stop the motor.

[0010] The beneficial effects of the present invention are:

[0011] By setting an automatic start-stop device, when loading, the material is placed on the inclined plate and falls onto the horizontal plate inside the feed hopper. The pressure sensor will detect the pressure index under the pressure of the material, and the pressure sensor itself will set a standard index.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figure 1-Figure 3 A heat treatment feed amount automatic control device includes a feed hopper 1. An automatic start-stop device is arranged inside the feed hopper 1. The automatic start-stop device includes a motor 2, a first stop switch 3, a second stop switch 4, a pressure sensor 5 and a forward and reverse switch 6. When the pressure sensor 5 is subjected to a certain pressure, the forward and reverse switch 6 controls the motor 2 to reverse its shaft. When the first stop switch 3 and the second stop switch 4 are started, the motor 2 stops.

[0018] like Figure 3 As shown, a mounting plate 11 is fixedly installed on the left side of the inner wall of the feed hopper 1, a motor 2 is fixedly installed on the outer surface of the mounting plate 11, a rotating rod 21 is fixedly connected to the rotating shaft of the motor 2, a gear 22 is fixedly installed on the outer surface of the rotating rod 21, when the motor 2 is started, the rotating shaft drives the rotating rod 21 to rotate, and the rotating rod 21 drives the gear 22 to rotate.

[0019] like Figure 2 As shown, a sliding plate 12 is slidably inserted into the left end of the feed hopper 1, and a gear rod 13 is fixedly installed on the lower surface of the sliding plate 12. The outer surface of the gear rod 13 meshes with the outer surface of the gear 22, and the outer surface of the gear rod 13 is slidably connected to the inside of the feed hopper 1. A mounting frame 14 is fixedly installed on the left side of the inner wall of the feed hopper 1 and located outside the motor 2. When the gear 22 rotates, it drives the gear rod 13 to move horizontally, and the gear rod 13 drives the sliding plate 12 to move inside the feed hopper 1, and the mounting frame 14 surrounds the motor 2 to prevent the material from interfering with the motor 2.

[0020] like Figure 2 As shown, the first stop switch 3 is fixedly installed inside the mounting frame 14, and the second stop switch 4 is fixedly installed on the right side of the inner wall of the feed hopper 1. The first stop switch 3 and the second stop switch 4 are both electrically connected to the motor 2 through wires, and a touch plate 15 is fixedly installed on the right end surface of the sliding plate 12. The first stop switch 3 and the second stop switch 4 can both control the motor 2 to stop, and the sliding plate 12 drives the touch plate 15 to move.

[0021] like Figure 2 and Figure 3 As shown, the pressure sensor 5 is fixedly installed inside the sliding plate 12, a horizontal plate 51 is fixedly installed on the upper surface of the pressure sensor 5, the forward and reverse switch 6 is fixedly installed on the lower inner wall of the mounting frame 14, the forward and reverse switch 6 is electrically connected to the pressure sensor 5 and the motor 2 through wires, and an alarm 16 is fixedly installed on the outer surface of the feed hopper 1, and the alarm 16 is electrically connected to the pressure sensor 5 through wires. When the material falls onto the horizontal plate 51, the pressure sensor 5 will detect the pressure index due to the pressure of the material, and when the value of the pressure sensor 5 exceeds a certain value, the alarm 16 will sound for convenient prompting.

[0022] like Figure 1 and Figure 2 As shown, an inclined plate 17 is fixedly installed on the inner upper end of the feed hopper 1, an electric telescopic rod 18 is fixedly installed inside the right end of the feed hopper 1, and a blocking plate 19 is fixedly installed on the left end of the electric telescopic rod 18. The blocking plate 19 is slidably inserted into the interior of the feed hopper 1, and the left end of the blocking plate 19 is flush with the lower right end of the inclined plate 17. The electric telescopic rod 18 is electrically connected to the pressure sensor 5 through a wire. The material falls from the inclined plate 17 to the horizontal plate 51 inside the feed hopper 1. When the electric telescopic rod 18 is started, it will control the movement of the blocking plate 19. The blocking plate 19 is close to the lower right end of the inclined plate 17 to limit the falling of the material.

[0023] By setting an automatic start-stop device, when loading, the material is placed on the inclined plate 17 and falls onto the horizontal plate 51 inside the feed hopper 1. The pressure sensor 5 will detect the pressure index under the pressure of the material. The pressure sensor 5 itself will set a standard index. When the value of the pressure sensor 5 reaches this value, the pressure sensor 5 transmits an electrical signal to the forward and reverse switch 6 to control the motor 2 to reverse the shaft, drive the rotating rod 21 to rotate, the rotating rod 21 drives the gear 22 to rotate, the gear 22 drives the gear rod 13 to move horizontally, and the gear rod 13 drives the sliding plate 12 to move to the right until the touch plate 15 squeezes the first stop switch 3 to stop the motor 2, so that the material on the horizontal plate 51 falls under the feed hopper 1, and at the same time the electric telescopic rod 18 will start to push the blocking plate 19 to the left and close to the lower right end of the inclined plate 17, so that the material can no longer fall. When the pressure sensor 5 detects a value that exceeds this value, the sliding plate 12 still does not move, and the alarm 16 will sound to indicate that the internal power structure is faulty, thereby achieving the effect of convenient and accurate grasp of the feed amount and being able to provide reminders.

[0024] Working principle: When loading, place the material on the inclined plate 17 and drop it onto the horizontal plate 51 inside the feed hopper 1. The pressure sensor 5 will detect the pressure index under the pressure of the material. The pressure sensor 5 itself will set a standard index. When the value of the pressure sensor 5 reaches this value, the pressure sensor 5 transmits an electrical signal to the forward and reverse switch 6 to control the motor 2 to reverse the shaft, drive the rotating rod 21 to rotate, the rotating rod 21 drives the gear 22 to rotate, the gear 22 drives the gear rod 13 to move horizontally, and the gear rod 13 drives the sliding plate 12 to move to the right until the touch plate 15 squeezes the first stop switch 3 to stop the motor 2, so that the material on the horizontal plate 51 falls under the feed hopper 1, and at the same time the electric telescopic rod 18 will start to push the blocking plate 19 to the left and close to the lower right end of the inclined plate 17, so that the material can no longer fall. When the pressure sensor 5 detects a value that exceeds this value, the sliding plate 12 still does not move. At this time, the alarm 16 will sound, indicating a fault in the internal power structure.
