Embodiment 1

[0030] see Figure 1-5 As shown, Embodiment 1 of the present invention discloses a mixer torque sensor, comprising an elastic body 1, a strain gauge 2, FCB3 and a cable assembly, FCB3 is electrically connected to the strain gauge 2 and the cable assembly respectively, and the strain gauge 2 and FCB3 are arranged on the elastic body 1, the elastic body 1 is provided with a mounting hole for accommodating and installing the motor K of the mixer, the center line of the elastic body 1 and the central axis of the motor K, the connecting shaft K1 of the motor K is exposed from the lower end of the elastic body 1, and the motor The connecting shaft K1 of K is connected with a stirring rod for stirring.

[0031] When the motor K is directly installed into the sensor and directly fixed with the sensor, when the motor K stirs, the elastic body 1 of the sensor is deformed by the reaction torque of the stirring rod, and the strain gauge 2 senses the deformation and then passes the Wheatst...

Embodiment 2

[0041] see Figure 1-5 As shown, Embodiment 2 of the present invention discloses a mixer, including a motor K, a stirring rod connected to the motor K, and the above-mentioned mixer torque sensor. The motor K is installed in the mounting hole, wherein the mounting hole is accommodated by the insertion hole 14, Hole 15 and escape hole 16 are formed, and concrete installation method is as above-mentioned. Because the agitator uses the above sensor, it can collect more accurate torque value when the motor is rotating, with higher measurement accuracy, better stability and wider measurement range, and the assembly method of the motor and sensor simplifies the overall structure , and more beautiful in appearance.

Abstract

The invention provides a stirring machine torque sensor and a stirring machine using the same, the sensor comprises an elastic body, a strain gauge, an FCB and a cable assembly, wherein the FCB is electrically connected with the strain gauge and the cable assembly respectively, the strain gauge and the FCB are arranged on the elastic body. A mounting hole for accommodating and mounting a motor of the stirring machine is formed in the elastic body, the central line of the elastic body is connected with the central axis of the motor, and a connecting shaft of the motor is exposed from the lower end part of the elastic body. According to the stirring machine torque sensor, the sensor and the motor are integrated together, that is, the motor is directly mounted in the sensor, so that the structure of the combination of the sensor and the motor is simplified, the central axis of the motor is easy to be consistent with the center of the sensor, and the precision and sensitivity of the sensor are further ensured, so that the sensor can acquire a more accurate torque value when the motor rotates.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a mixer torque sensor and a mixer. Background technique [0002] With the impact of the global epidemic, people have paid unprecedented attention to the medical industry. Among them, the mixer for mixing pharmaceutical formulas has also developed rapidly with the explosive growth of the medical industry. The existing mixer mainly includes a stirring rod, a motor that drives the stirring rod to rotate, and a sensor responsible for collecting the torque value when the motor rotates. One end of the sensor is fixedly connected to the upper part of the motor, and the other end of the sensor is fixed on the installation table. When the motor rotates When torque is generated, the sensor senses the torque value. [0003] However, the existing mixer has a relatively long assembly structure. If you want to obtain higher-precision mixing data, you must have a high degree of center position...
