[0005] A measurement correction device, wherein a reduction motor (301) is mounted on a motor base (302); a spring wire winding rod (304) and a weight wire winding device (305) are fixedly connected to the shaft of the reduction motor (301) in sequence from left to right along the same axis; a spring wire (3012) is wound along a spring wire groove (3019) of the spring wire winding rod; a weight wire (309) is wound along a weight wire groove (3020) of the weight wire winding device; and a winding direction (3021) of the spring wire is opposite to a winding direction (3022) of the weight wire; the motor base is fixed on a top plate of a base (303); and the top plate of the base is A weight reset fixing seat (308) is fixed at the position of the bottom surface facing the weight line. The weight reset fixing seat is a conical cylinder with a small top and a large bottom for allowing the weight (3010) to enter from the bottom to the top and preventing it from passing through. A circular hole with the same size as the top opening of the conical cylinder is opened on the top plate of the base. A weight line guide ring (3024) is fixed on the top plate of the base by screws. The weight line passes through the weight line guide ring, the circular hole on the top plate of the base and the weight reset fixing seat in sequence downward along the weight line reel. A weight (3010) for measurement correction is fixedly connected to the lower end; the clockwork disk (301 4) is installed on a vertical plate (3015) fixed to the bottom surface of the top plate of the base, and the pulley (3011) is fixed on the vertical plate (3015); the left end of the spring sheet (3013) is fixed to the bottom surface of the top plate of the base by a screw; the clockwork line passes vertically downward along the clockwork line winding rod through the through hole on the top plate of the base and the lower end of the small hole (3023) on the right end of the spring sheet, and then passes around the pulley and connects to the clockwork of the clockwork disc in a horizontal left direction; the bottom surface of the top plate of the base is installed with a weight in place touch switch (306) and a weight reset touch switch (307); the clockwork line located below the spring sheet A positioning joint (3018) is arranged on the top, which cannot pass through the small hole (3023) at the right end of the spring sheet; the weighing pan (3016) is arranged directly below the weight; when the weight moves downward along with the weight line and falls into the weighing pan, at the same time, the positioning joint of the clockwork line moves upward and triggers the weight in place touch switch by lifting the spring sheet, thereby controlling the motor to stop rotating; when the weight moves upward along with the weight line and enters the weight reset fixing seat and triggers the weight reset touch switch at the same time, thereby controlling the motor to stop rotating, at the same time, the clockwork line moves downward due to the tension of the clockwork spring, and the positioning joint of the clockwork line moves downward and resets;

[0008] The present invention has the following technical features and advantages:

[0009] 1. Freely retractable: A motor cooperates with the spring disk to realize the retraction and extension of the clockwork line and the weight line. The winding directions of the clockwork line and the weight line are opposite. When the clockwork line is retracted, the weight line is released, and when the weight line is retracted, the clockwork line is released, thereby realizing the retraction and extension function of the weight.

[0010] 2. Short line controls long line: Utilize the difference in radius of the wire groove of the mainspring wire winding rod and the weight wire winding rod to achieve the effect of amplifying the length of the weight wire. Only a small section of the mainspring wire is needed to achieve the retraction and release of a large section of the weight wire, which can be used in situations that are far away from the scale pan.

[0011] 3. Accurate positioning: The length of the weight line can be accurately positioned by setting the position of the positioning section on the mainspring, which is suitable for the placement of weights for measurement and calibration at different heights.

[0012] 4. Accurate measurement: Uniformly customize weights to achieve accurate calibration of measurement and calibration devices.

[0013] 5. Small error: The weight line is made of lightweight and high-strength customized line, and the impact on the correction error is almost zero.

[0014] 6. Shockproof protection: The inner circle of the weight collection and fixing seat is covered with protective foam to prevent the weight from being affected by vibration during transportation and work.

[0015] The present invention is specially used for the metering calibration of the "Chinese herbal medicine piece metering, pushing and turning device" (i.e. the metering and pushing device) in the patent application of the present inventor. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Working process:

[0026] 1. The control system issues a "measurement calibration" command;

[0027] 2. The motor works, driving the winding rod of the mainspring line and the winding rod of the weight line to rotate;

[0028] 3. The weight line reel releases the weight line and gently puts the weight down. At the same time, the weight releases the reset touch switch, and the control system detects that the weight has moved.

[0029] 4. While the weight is moving, the winding rod reels in the winding wire, pulls the winding wire out of the winding disk, turns the pulley, passes through the small hole at one end of the spring sheet, and winds it into the wire groove in the winding rod.

[0030] 5. The weight continues to drop until it falls into the scale pan. The weight is no longer subject to any tension. The motor continues to work for a certain period of time before stopping. The weight line winder continues to rotate for a certain period of time to release more weight line, leaving the extra weight line hanging in the air so that it does not affect the accuracy of the weight. The length of "the motor continues to work for a certain period of time" is controlled by the positioning node on the clockwork line and needs to be set in advance.

[0031] 6. After the weight falls onto the scale pan, the positioning node fixed on the mainspring passes through the pulley and reaches the spring sheet. Since the positioning node is larger than the small hole of the spring sheet, the mainspring continues to be retracted, which will move the spring sheet. The spring sheet will press the weight into place and touch the switch paddle. The system detects that the weight has reached the predetermined position and controls the motor to stop rotating.

[0032] 7. The control system controls the metering push device to automatically perform metering calibration.

[0033] 8. After the automatic metering and calibration of the metering push device is completed, the control system controls the motor to rotate in the opposite direction. The weight line winder reels in the weight line and lifts the weight. The spring line winding rod releases the spring line. The spring line is pulled by the spring and wound into the spring disk. The positioning node goes back with the spring line, the spring sheet rebounds, and the weight is released to touch the switch. The control system detects the weight and starts the return journey.

[0034] 9. The weight continues to rise and enters the weight reset fixing seat. The weight is fixed and the paddle of the weight reset touch switch is pressed. The system detects that the weight reaches the initial fixed position and controls the motor to stop rotating.

[0035] 10. Metrology calibration is completed.
