[0002] The refrigerator liner is an important component of the refrigerator body. It is located in the inner layer of the box body (including the door body) and is used to separate the refrigeration and freezing space from the insulation layer, and store food through accessories such as ice cabinets, shelves and fruit and vegetable boxes.

[0003] After the refrigerator liner is injection molded, burrs will form around it. At this time, the burrs around it need to be cut. During the cutting process, the end face needs to be fixed, and then the burr surface is processed on one side. After the single-side processing is completed, the fixation is released, and then the direction is turned to continue cutting and grinding. This operation process is too cumbersome, and each end face needs to be fixed before processing, which increases the time for cutting and grinding. Utility Model Content
