The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 4, the present embodiment provides a rechecking scale for an automatic packaging and weighing production line, which includes a support 100 in a square frame shape, wherein weighing sensors 200 are respectively disposed at four corners of the top of the support 100, a conveyor belt 300 is disposed above the weighing sensors 200, and the conveyor belt 300 is connected to a motor 400; wherein, be provided with connecting block 500 between weighing sensor 200 and the conveyer belt 300, connecting block 500 is horizontal "E" type structure, and conveyer belt 300 is connected at its top, and linking bridge 100 can be dismantled through guard column 600 in one side of bottom, and the opposite side of bottom passes through sensor briquetting 700 and connects weighing sensor 200. The function of the protection column 600 is to protect the load cell 200 from being hit during transportation of the rechecking scale; or when the rechecking scale is not used, the support function is realized, the service life of the weighing sensor 200 is prolonged, and the phenomenon that the precision of the weighing sensor 200 is reduced due to the irreparable deformation of the weighing sensor 200 caused by mechanical fatigue is prevented. Load cell 200 is preferably, but not limited to, a bellows load cell. The motor 400 is preferably, but not limited to, a reduction motor.

Further, the bottom of the bracket 100 may be preferably provided with a lifting support leg 110, and the lifting support leg 110 is used for adjusting the height of the bracket 100, so that the conveyor belt 300 is flush with the material packaging bag to be reinspected, which is about to arrive at the upstream end, and the vibration of the whole reinspection scale is reduced.

More specifically, the sensor pressing block 700 comprises an upper cover 710 and a lower cover 720, wherein the upper cover 710 is connected to the connecting block 500, and the lower cover 720 is connected to the weighing sensor 200; a steel ball 730 is wrapped between the upper cover 710 and the lower cover 720. The force transmission mode adopting point contact can effectively prevent the weighing sensor 200 from measuring inaccurately due to unbalanced stress.

As another preferable scheme, a buffer protection layer 721 is further disposed on the inner surface of the lower cover 720. The buffer protection layer 721 may be, but is not limited to, PVC or urethane resin, and functions to mainly protect the outer surface of the steel ball 730 from mechanical damage. Further, the inner surface of the upper cover 710 may also be provided with such a buffer protection layer.

As another preferable mode, a vertical notch 722 is further preferably formed in the bottom of the inner surface of the lower cover 720, so that when the steel ball 730 is pressed downward by an external force, both sides of the lower cover 720 are slightly deformed toward the axial center, and a wrapping force toward the axial center is generated on the steel ball 730, thereby further suppressing the dispersion of the external force, improving the detection accuracy of the load cell 200, and the deformation has a certain damping and buffering effect on the conveyor belt 300, reducing the generation of invalid dynamic data, and improving the weighing efficiency.

Further, the conveyer belt 300 both sides are preferably provided with adjustable baffle 800 to carry out certain spacing to the material, supplementary material on the stable conveyer belt 300, prevent that it from further producing vibrations.

Still further, counters 900 are also preferably provided on both sides of the conveyor belt 300 to facilitate automated management control.

The working process of the rechecking scale is as follows: the protection column 600 is removed or the nut on the protection column 600 is unscrewed. No matter whether a material exists on the conveyor belt 300 or not, the weighing sensor 200 continuously performs real-time dynamic weighing, when the material runs onto the conveyor belt 300 of the present case from an upstream conveyor belt, the weight of the conveyor belt 300 changes, the generated pressure change is transmitted to the weighing sensor 200 through the sensor pressing block 700, the weighing sensor 200 senses that dynamic data changes, and a background controller (the prior art, which is not the invention point of the present case) calculates the weight of the corresponding material; the material is directed by the adjustable baffle 800 and then passes through the counter 900, whereupon the material continues on to the next conveyor.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
