Novel refrigerator liner trimming device

Abstract

The invention discloses a novel refrigerator liner trimming device and belongs to the technical field of refrigerator liner manufacturing. The trimming device comprises a pedestal, left and right vertical plates arranged at two sides of the pedestal, and upper and lower blade mounting racks fixed on the left and right vertical plates, wherein the lower blade mounting rack is fixed on the left and right vertical plates through a linear guide rail; upper and lower blades are mounted on the upper and lower blade mounting racks; a main shaft is fixedly arranged at the lower end of the left and right vertical plates; eccentric wheels are fixedly arranged at two ends of the main shaft; a pendulum rod is connected with the eccentric wheels and fixed on the lower blade mounting to drive the lower blades to move; a motor is connected with the main shaft. The novel refrigerator liner trimming device has the advantages of being simple in structure, convenient to mount and low in trimming noise; the linear guide rail is connected with the lower blade rack and a vertical column, the friction is small and the linear guide rail is used for ensuring that the lower cutting blades smoothly move upwards and downwards; cam mechanisms are connected with two ends of the main shaft; the motor drives the cam mechanisms to lift up and down synchronously; the lower blades moves up and down in parallel and completes trimming with the cooperation of the lower cutting blades; the upper and lower blades are arranged in a wave-like style, so as to guarantee cutting force of the cutting blades.

Description

technical field [0001] The invention relates to the technical field of refrigerator liner production, in particular to a novel refrigerator liner trimming device. Background technique [0002] The inner liner of the refrigerator adopts the blister molding process. The inner liner formed by the blister molding needs to be trimmed due to the seemingly and redundant corners of the corners. At present, most of the inner liner trimming of the refrigerators on the market is manually trimmed during production. Or use the equipment for upper knife trimming, the production efficiency of manual trimming is low, the structure of the upper knife trimming equipment is complex, and the thickness of trimming is not accurate. Contents of the invention [0003] The purpose of the present invention is to provide a new type of refrigerator liner trimming equipment. In order to overcome the above-mentioned defects of the existing mechanism, the present invention has simple structure, conven...
