Description

Technical Field

[0001] This application relates to the field of surge arrester manufacturing technology, and in particular to an automatic silicone strip cutting and weighing device for surge arresters. Background Technology

[0002] In areas prone to lightning strikes, surge arresters are widely used as electrical devices to protect electrical equipment from transient overvoltage damage and limit the duration and amplitude of follow current. The structure of a surge arrester includes a core and silicone skirts that are hot-pressed onto the core using a thermoforming machine. During production, the silicone material fed into the thermoforming machine is first pressed into sheet form by a mixing mill, then cut into corresponding rectangular shapes and processed into skirts using appropriate molds.

[0003] For example, Chinese patent application number CN201921289083.5 discloses a silicone material cutting device before hot pressing molding of a surge arrester silicone umbrella skirt. The device includes a table, a tray on the table and a gantry fixedly connected thereto. Multiple cylinders are installed on the gantry, and the piston rods of each cylinder are fixedly connected to a top plate. A silicone material cutting knife is provided below the top plate. The cutting knife includes a grid-shaped structure composed of multiple longitudinal blades and multiple transverse blades, and the grid-shaped structure is fixedly connected to the top plate.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] To ensure the quality of the final silicone umbrella skirt, the square blanks need to be weighed after the silicone sheets are cut. However, the efficiency of manually transferring and weighing the blanks is low and the operation is cumbersome, making it difficult to guarantee accurate weighing and also hindering the production efficiency of the silicone umbrella skirt.
