[0020] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below. In the following description, a lot of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] Comparative example

[0022] In the commonly used filling equipment, the puncture device is not designed on the filling roller, but a conventional contact conductive structure is adopted, which is connected to the surface of the steel drum. Because the surface of the steel drum is often painted to achieve the effect of rust and dirt prevention. However, due to the paint treatment, a layer of paint film is formed on the surface of the steel drum, which is insulating and cannot conduct electricity. If static electricity is left on the steel drum, it cannot be discharged through the direct contact with the grounding wire. Therefore, the grounding equipment of the existing filling equipment is invalid, which is difficult to meet the explosion-proof requirement of the filling equipment.

[0023] Example

[0024] As Figures 1-4 The utility model provides a kind of piercing device of weighing roller for filling line, including fixed seat 10, drive cylinder 20 and piercing vertical knife 30, the drive cylinder 20 is installed on fixed seat 10, the piercing vertical knife 30 is installed in the telescopic end of drive cylinder 20, the blade of piercing vertical knife 30 is vertically arranged, and piercing vertical knife 30 is steel, and piercing vertical knife 30 is ground.

[0025] The fixed seat 10 is provided with screw connection structure etc., for fixing the fixed seat in the side of weighing roller, the upper surface of fixed seat 10 is substantially aligned with the upper surface of weighing roller;Drive cylinder 20 includes fixed cylinder body and telescopic end, fixed cylinder body is directly fixedly connected with fixed seat 10, and its telescopic end faces the direction of weighing roller, and the telescopic direction of telescopic end is perpendicular to the conveying direction of weighing roller;Piercing vertical knife 30 is driven by drive cylinder 20 and advances to the direction of weighing roller, and piercing vertical knife 30 is connected in the telescopic end of drive cylinder, and the height of piercing vertical knife 30 is slightly higher than the upper surface of weighing roller, so that when steel drum is conveyed on weighing roller, it can advance to steel drum by piercing vertical knife 30, and the blade of piercing vertical knife 30 can be connected with the bottom edge of steel drum, and in the connecting process, the blade of piercing vertical knife 30 can penetrate the paint surface of steel drum, so as to be stably electrically connected with the metal barrel of steel drum body, and the blade 30 is also connected with ground wire, so that static electricity on steel drum can be discharged, to ensure the requirement of explosion-proof filling, so that filling accident caused by static electricity can be avoided.
