DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following is a clear and complete description of the technical solution of the present invention in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional terms used are used to illustrate rather than limit the invention.

[0025] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0026] According to the embodiment of the present invention, an automatic calibration weighing device is provided. Figures 1 to 3 , including a weighing waiting unit 100, a weighing conveying line 200 and a lifting and transferring unit 300; wherein, a calibration piece is arranged above the weighing waiting unit 100; a weighing station 201 is arranged above the weighing conveying line 200; the lifting and transferring unit 300 is arranged between the weighing waiting unit 100 and the input end of the weighing conveying line 200, and a reversing unit 400 is connected between the output end of the weighing conveying line 200 and the lifting and transferring unit 300, and the lifting and transferring unit 300 is used to transport the calibration piece to the weighing waiting unit 100 or the input end of the weighing conveying line 200.

[0027] It should be noted that the weighing waiting unit 100 is used to cache the verification parts, and a platform scale is provided at the weighing station 201. Figure 1The middle arrow indicates that before each shift, the calibration operation is started. The calibration part located above the weighing waiting unit 100 is transferred to the input end of the weighing conveyor line 200 via the lifting and transferring unit 300. Under the conveying action of the weighing conveyor line 200, the calibration part arrives at the corresponding weighing station 201 in sequence. When the weight difference between the weighing data of the weighing station 201 and the weight of the calibration part is within the error range, the calibration of the weighing station 201 is passed. If it exceeds the error range, the machine is shut down. By adding the weighing waiting unit 100 and the lifting and transferring unit 300, the purpose of automatic calibration and error prevention is achieved, thereby avoiding quality problems caused by the scale's out-of-tolerance operation due to manual error or illegal operation, reducing manual participation and saving labor costs.

[0028] In the automatic calibration weighing device of this embodiment, please refer to Figures 1 to 3 The weighing waiting unit 100 includes a first frame 101 and a plurality of first rollers 102 rotatable relative to the first frame 101. A first drive element is provided on the first frame 101, and the plurality of first rollers 102 are sequentially connected in a transmission manner, with one first roller 102 being in a transmission manner connected to the first drive element. The calibration component is placed in a calibration barrel 500.

[0029] It should be noted that activating the first drive element can drive the first rollers 102 to operate to transport the calibration barrel 500. By controlling the first drive element, the first rollers 102 can rotate forward and reverse. At the same time, two position detection sensors are configured at the weighing waiting unit 100 to detect the start and stop positions of the calibration barrel 500.

[0030] Specifically, the bottom of the calibration barrel 500 is set to be square, and the barrel body of the calibration barrel 500 is set to be cylindrical. The calibration parts are placed in the calibration barrel 500 to facilitate transmission through the first roller 102.

[0031] In the automatic calibration weighing device of this embodiment, please refer to Figures 1 to 3 The lifting and transplanting unit 300 includes a plurality of second rollers, which are sequentially connected in transmission and rotatably arranged on a second frame, and a second driving element is provided on the second frame, wherein one of the second rollers is connected in transmission to the second driving element.

[0032] It should be noted that, by starting the second driving element, a plurality of second rollers can be driven to operate so as to transport the calibration barrel 500 .

[0033] In the automatic calibration weighing device of this embodiment, please refer to Figures 1 to 3 The lifting and transplanting unit 300 further includes a lifting cylinder, the telescopic direction of the lifting cylinder is parallel to the height direction of the second frame, and a bearing plate is provided at the telescopic end of the lifting cylinder.

[0034] Specifically, the setting height of the first roller 102 is greater than the setting height of the second roller, and the setting height of the second roller is flush with the setting height of the weighing conveyor line 200.

[0035] It should be noted that the lifting cylinder can lift the load plate, and a position detection sensor is provided at the lifting and transporting unit 300 to ensure the positioning of the calibration barrel 500. After the calibration operation is initiated, the lifting cylinder extends, and the weighing waiting unit 100 rotates forward. When the calibration barrel 500 is transported to the position detection sensor of the lifting and transporting unit 300, the lifting cylinder extends and retracts, and the calibration barrel 500 falls onto the second roller. At the same time, a lifting transmission belt can be provided between adjacent second rollers. The transmission direction of the lifting transmission belt is perpendicular to the transmission direction of the second rollers, and the setting height of the lifting transmission belt is the same as the setting height of the second rollers to achieve reversing transmission of the calibration barrel 500.

[0036] In the automatic calibration weighing device of this embodiment, please refer to Figures 1 to 3 The weighing conveyor line 200 includes a plurality of third rollers 203, which are sequentially connected in transmission and rotatably arranged on a third frame 202. A third driving element 204 is arranged on the third frame 202, and one of the third rollers 203 is connected in transmission to the third driving element 204.

[0037] It should be noted that activating the third drive element 204 drives the plurality of third rollers 203 to operate, thereby transporting the check bucket 500. Furthermore, a weighing transmission belt is provided at the weighing station 201. The weighing transmission belt's transmission direction is the same as that of the third rollers, and is used to transport the check bucket to the weighing station 201. A liftable scale is provided between the symmetrically arranged weighing transmission belts for weighing.

[0038] In the automatic calibration weighing device of this embodiment, please refer to Figures 1 to 3 , also including a controller, the weighing station 201 is provided with an alarm and a position detection sensor, the position detection sensor, the platform scale and the alarm are all connected to the controller.

[0039] It should be noted that after the position detection sensor at the weighing station 201 detects the calibration barrel 500, the controller lifts the corresponding scale for weighing. At the same time, the controller compares the weighing data of the scale with the calibration weight (the total weight of the calibration part and the calibration barrel). If the difference between the two is within the error range, the calibration is passed. Otherwise, the machine stops and an alarm is sounded. After completing the calibration of the scales at several weighing stations 201 in sequence, the calibration barrel 500 is transferred to the lifting and transplanting unit 300 again through the reversing unit 400, and after being lifted, it returns to the weighing waiting unit 100. In addition, the reversing unit 400 adopts a combination of rollers and transmission belts, wherein the transmission direction of the transmission belt is perpendicular to the transmission direction of the rollers to achieve reversal.

[0040] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
