[0012] The utility model has the following beneficial effects:
[0013] The weighing module of the utility model is convenient for calibrating the weighing sensor.
[0014] In order to more clearly illustrate the structural features and functions of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 This is an exploded view of the weighing module mentioned in the utility model.
[0016] Figure 2 This is a schematic diagram of the structure of the weighing module mentioned in the utility model. DETAILED DESCRIPTION
[0017] The present invention will be further described below in conjunction with the accompanying drawings and related knowledge, and described clearly and completely. Obviously, the described application is only a part of the embodiments of the present invention, rather than all of the embodiments.
[0018] Reference Figure 1-Figure 2 As shown, the weighing module of the utility model includes a base 1, on which a lifting motor 2 and a weighing sensor 3 are arranged, and a lifting bracket 4 is arranged on the lifting motor 2 for lifting a weight 5; a crossbeam 6 is arranged on the weighing sensor 3, and the crossbeam 6 is used to place the weight 5.
[0019] Reference Figure 1 As shown, the working process of the utility model is: when calibration is needed, the lifting bracket 4 is driven to descend by the lifting motor 2 until it descends to place the weight 5 on the beam 6. At this time, the upper end of the lifting bracket 4 is separated from the weight 5. At this time, the weight loaded on the weighing sensor 3 is the weight of the weight. If the weighing result of the weighing module is inconsistent with the weight of the weight, it means that the weighing module needs to be recalibrated; after the calibration is completed, the weight 5 is lifted by the lifting motor 2 until the weight 5 is separated from the beam 6, thereby completing the entire calibration process; when recalibration is needed next time, the weight 5 is placed on the beam 6 to complete the calibration; the weighing module of the utility model is novel in design and simple in result.
[0020] As a further improvement, a weighing platform 7 is provided at one end of the crossbeam, and a slot 8 is provided at the other end for placing a weight 5. The slot 8 is just used to engage the weight, and the weighing platform 7 is used to weigh other items after calibration. The slot 8 can be used for the lifting bracket 4 to pass through, that is, the width of the lifting bracket 4 is smaller than the width of the slot 8.
[0021] As a further improvement, a limit switch 9 is respectively provided at the upper end and the lower end of the lifting motor for limiting the rising and falling; the lifting motor is fixedly installed by a motor bracket 13.
[0022] As a further improvement, the lifting bracket 4 is provided with a protrusion 10, which is movably connected to the weight 5, and is used to lift the weight 5 during the rising process and to facilitate separation from the weight 5 during the descending process.
[0023] As a further improvement, a hollow structure for the guide column 11 to move is provided on one side of the lifting bracket 4 (in Figure 1 (not shown) By providing the guide column 11, the lifting bracket 4 can be prevented from rotating during the rising process.
[0024] As a further improvement, a screw rod 12 is provided on the lifting motor, and the screw rod 12 is connected to the threaded hole in the lifting bracket 4. The lifting bracket 4 is driven to ascend or descend by the rotation of the screw rod 12 of the lifting motor.
[0025] The technical principle of the utility model is described above in combination with the specific embodiments, which are only the preferred implementation methods of the utility model. The protection scope of the utility model is not limited to the above embodiments, and all technical solutions under the idea of the utility model belong to the protection scope of the utility model. Those skilled in the art can think of other specific implementation methods of the utility model without creative labor, and these methods will fall within the protection scope of the utility model.
