Corner cutting mechanism for refrigerator door sealing strip

Abstract

The invention relates to the technical field of refrigerator door sealing strip production devices, and discloses a corner cutting mechanism for a refrigerator door sealing strip. The corner cutting mechanism comprises a cutting mold and at least two blade grooves, wherein the cutting mold comprises a rubber strip guide groove, the rubber strip guide groove is formed in the cutting mold in a penetrating mode so that the refrigerator door sealing strip can pass through the rubber strip guide groove, and a protruding mechanism which is matched with the refrigerator door sealing strip to be limited in the vertical direction is arranged in the rubber strip guide groove; the at least two blade grooves are formed in the top of the cutting mold and are connected with the rubber strip guide groove so that blades located at the top can cut the refrigerator door sealing strip; and the refrigerator door sealing strip penetrates through the rubber strip guide groove, a driving assembly drives the at least two blades to enter the corresponding blade grooves and carry out corner cutting on the refrigerator door sealing strip, the waste sealing strip subjected to corner cutting falls into a waste groove, the whole corner cutting process is carried out in the cutting mold, safety and reliability are achieved, moreover, the blades do not need to be in a water vapor environment for a long time, the service life of the corner cutting mechanism is effectively prolonged, and the safety of the corner cutting mechanism is effectively improved.

Description

technical field [0001] The invention relates to the technical field of production devices for refrigerator door sealing strips, in particular to a corner cutting mechanism for refrigerator door sealing strips. Background technique [0002] The refrigerator door seal strip is composed of a sealant strip and a soft magnetic strip. A semi-finished refrigerator door seal strip is formed by inserting the soft magnetic strip into the corner-cut seal strip. Fusion welding, just made the finished refrigerator door seal. [0003] In the current production process of refrigerator door seal strips, upper and lower cutting machines and horizontal cutting machines are generally used for corner cutting. Connected, the cylinder drives the rotating blade to move forward and backward horizontally or up and down to complete the corner cutting action. The method of cutting the corners of the sealing strip by driving the rotary blade with the cylinder has certain potential safety hazards, and...
