Technical Field
[0001] This utility model belongs to the field of pulp molding product processing technology, and more specifically, it relates to a calibration device for pulp molding product forming. Background Technology
[0002] Pulp molding products require molding equipment during production. The sliding arm on the molding equipment moves the top mold to the bottom mold position. The top mold and bottom mold combine to form the pulp molding product. In order to ensure that the top mold and bottom mold are accurately aligned, calibration equipment is required. The calibration equipment is installed on the molding equipment. When the top mold moves to the bottom mold position, the calibration equipment ensures that the top mold moves in an accurate position.
[0003] According to CN201920013629.8, this utility model discloses an automatic reset calibration device for pulp molding equipment, including a molding machine and a grating ruler body. The molding machine includes a machine bed, with a first station, a second station, and a third station on the top of the machine bed. A reciprocating worktable is movably arranged on the first, second, and third stations. A drive mechanism is provided on the front and rear sides of the reciprocating worktable. The grating ruler body includes a scale grating and a grating reading head. This utility model, by supplementing the existing machine tool accuracy benchmark with grating ruler technology and cooperating with program control, completes the device's process from signal sensing, feedback control system, program calculation compensation, and transmission of instructions to the servo motor, driving the lead screw to compensate for the offset value, thereby achieving the positioning and setting accuracy value of the worktable, enabling the equipment itself to obtain a higher accuracy value, and thus allowing the mold fixtures on the equipment to achieve a good service life.

The grating is usually installed on the outside of the equipment, close to the molding and processing area. When the molding equipment molds pulp products, it generates product debris, which adheres to the grating position, affecting the grating's normal signal reception and thus affecting the equipment calibration.
