Description

TECHNICAL FIELD

[0001] The utility model relates to a high -speed feeding mechanism of gate opening size can be infinitely adjustable. BACKGROUND

[0002] The flow rate of the feeding mechanism when discharging is one of the factors affecting the accuracy of the electronic quantitative packaging scale. The discharge port of the feeding mechanism is usually provided with an arc-shaped gate. By controlling the arc-shaped gate and other auxiliary mechanisms, the material can be added at a fast, medium or slow rate, thereby effectively controlling the flow rate, accuracy and speed of the material. A common control method currently is to use multiple cylinders or a single cylinder in combination with a vibration mechanism to control the slow addition of the material. This feeding method has a long feeding time, a complex structure and high cost. Another feeding method is to use a single cylinder for control. However, the opening and closing degree of the gate is limited by the stroke of the cylinder, and only a single on-off can be achieved, and intermediate adjustment of the opening and closing degree of the gate cannot be achieved. A third method is to use multiple cylinders or multiple cylinders for auxiliary control. Although this method can set different opening degrees of the feeding port, it cannot accurately adjust the flow rate of the material, and the structure is relatively more complex. SUMMARY

[0003] The utility model improves the above problems. That is, the utility model provides a high-speed feeding mechanism with infinitely adjustable gate opening size, which is simple in structure and convenient to use.

The rotating shaft and the gate are connected through a swing arm. The rotating shaft is driven to rotate by a power source to change the opening size between the gate and the discharge end of the feeding tank.

[0005] Further, the opening between the gate and the discharge end of the feeding tank can be adjusted to a fast-adding opening, a medium-adding opening, a slow-adding opening or a closed opening. The size of the fast-adding opening is larger than that of the medium-adding opening, and the size of the medium-adding opening is larger than that of the slow-adding opening.

[0006] Further, the power source is an electric motor.

[0007] Further, the utility model further comprises a machine base. The feeding tank is arranged inside the machine base. The rotating shaft is connected to the machine base through a bearing seat.

[0008] Further, a mounting slot is arranged at the side of the machine base. The end of the rotating shaft extends into the mounting slot. The end of the rotating shaft extending into the mounting slot is provided with a proximity block.

[0009] Further, a sensor lock plate is arranged in the mounting slot. A sensor is mounted on the sensor lock plate. The sensor and the proximity block can cooperate to sense.

[0010] Furthermore, the lower part of the swing arm is fixed to the gate via a positioning component, and the upper part of the swing arm has a fixing groove for fixing the rotating shaft.

[0011] Furthermore, the top of the swing arm is provided with a slot, which is connected to the fixing slot.

[0012] Furthermore, a fixing member is installed at the top of the swing arm, and the fixing member passes through the swing arm and the slot.

Power is transmitted to the rotating shaft through a power source, which drives the gate to open or close via a swing arm.

[0020] Example 1: As Figures 1-4 As shown, a high-speed feeding mechanism with infinitely adjustable gate opening size is provided, including a feeding trough 1 and a gate 6 disposed at the discharge end of the feeding trough. A rotating shaft 2 is disposed above the gate, and the rotating shaft is connected to the gate via a swing arm 5. The rotating shaft is driven to rotate by a power source 7 to change the size of the opening 11 between the gate and the discharge end of the feeding trough.

[0021] In work, power is transmitted to the rotating shaft through the power source, so that the rotating shaft drives the gate to open or close through the swing arm, the opening size between the gate and the discharge end of the feeding groove is adjusted according to the actual situation, so that the three position adjustments of fast feeding, medium feeding and slow feeding can be realized, and then the feeding speed is adjusted to achieve the accurate weighing target value; after the feeding is completed, the gate is completely closed, so that the material cannot continue to be discharged.

[0022] The feeding groove is funnel-shaped, the upper end of the feeding groove is a feeding port, and the lower end of the feeding groove is a discharge port.

[0023] In the embodiment of the utility model, the opening between the gate and the discharge end of the feeding groove can be adjusted to be a fast feeding opening, a medium feeding opening, a slow feeding opening or a closed opening, the size of the fast feeding opening is larger than that of the medium feeding opening, and the size of the medium feeding opening is larger than that of the slow feeding opening.

[0024] When the opening between the gate and the discharge end of the feeding groove is the largest, it is the fast feeding opening, when the opening is of medium size, it is the medium feeding opening, and when the opening is smaller, it is the slow feeding opening; when it is the fast feeding opening, the feeding speed of the material is very fast, and the flow is large; when it is the medium feeding opening, the feeding speed of the material is a little smaller; and when it is the slow feeding opening, the flow of the material is small, and the feeding is uniform and accurate.

[0025] In the embodiment of the utility model, the power source is a motor; the power source is connected with one end of the rotating shaft away from the proximity block; and the power source further comprises a speed reducer.

[0032] In the embodiment of the utility model, a sensor lock piece 9 is arranged in the mounting slot, a sensor 10 is arranged on the sensor lock piece, and the sensor and the proximity block can cooperate to sense.

[0033] The sensor 10 sets the initial position of the gate by detecting the side of the proximity block 3 mounted on the rotating shaft 2 as the zero position of the motor rotation angle. The initial value is recorded as zero, and the gate opening percentage is set to achieve the adjustment of the fast, medium and slow three positions, and then the feed speed is adjusted to achieve the accurate weighing target value. The parameter values of the three opening degrees of fast, medium and slow can be set according to the flowability of the actual material.

[0034] In the embodiment of the utility model, the working steps are as follows: the equipment is started, the zero value of the gate rotation is set, and then the slow, medium and fast values are preset respectively; the material is discharged, the material is input into the feed slot 1, the power source 7 drives the rotating shaft 2 to rotate clockwise, the gate is opened to the preset fast value range, and then the material is fast added; after the material is discharged to the preset time parameter, the power source 7 drives the rotating shaft 2 to rotate counterclockwise to reach the position of the target value according to the set medium target value range; after the material is discharged to the preset time parameter, the power source 7 drives the rotating shaft 2 to continue to rotate counterclockwise to reach the position of the target value according to the set slow target value, at this time, the material is discharged through the slow adding port (the slow adding port is a small port) at the bottom of the side of the gate, the material flow of the slow adding port is small, and the feeding is uniform and accurate; when the preset time parameter is reached, the power source 7 drives the rotating shaft 2 to continue to rotate counterclockwise until the slow adding port is closed, that is, when the sensor 10 on the sensor locking plate 9 detects the proximity block 3, the gate 6 of the feed slot 1 is completely closed.

[0035] The device can adjust the preset fast, medium and slow values according to the deviation of the weight of the actual material from the set weight, and when the error value of the material weight meets the accuracy requirement, the parameter value setting of the material is completed, and then batch production can be started.
