Description

Technical Field

[0001] The invention relates to an undercutting machine for inner tank of a dishwasher, in particular to an undercutting machine for inner tank of a dishwasher of multiple models. Background Art

[0002] The traditional turntable dishwasher liner biting machine has its knives evenly distributed on a large round turntable, which bites the three edges of the liner's U-shaped middle plate, top plate and bottom plate through one rotation of the large round turntable. Figure 1 ) is composed of 5 surfaces, namely the U-shaped middle plate, the top plate and the bottom plate. The top plate side is composed of a hob group consisting of 6 cutters. When biting the top plate side, the cutters rotate parallel to the top plate plane, and the top plate and the three edges of the U-shaped middle plate are bit together at one time; the bottom plate side is also composed of a hob group consisting of 6 cutters. When biting the bottom plate side, the cutters rotate parallel to the bottom plate plane, and the three edges of the bottom plate and the U-shaped middle plate are bit together at one time. To bit one liner, the large plate needs to rotate 2 circles.

[0003] Newly developed liner (see Figure 2 ) has four sides, namely the left middle plate, the right middle plate, the top plate and the bottom plate. Since one side is missing, only four straight edges need to be bitten. In order to improve the biting efficiency, the newly developed biting machine no longer uses a turntable biting, but a four-edge straight-pull biting. Four sets of rollers are arranged in parallel. A set of rollers is composed of multiple knives with different knife shapes. A set of rollers moves from top to bottom once to bite one edge. The four sets of rollers move synchronously from top to bottom once to bite all four edges of the liner. In order to improve the biting efficiency, the double-station trolley continues to be used. The loading time of the double-station trolley and the tool return time overlap, which can save 10 seconds of process overlap time and improve the biting rhythm. The turntable dishwasher liner biting machine bites a large liner plate for at least 2 turns, and the working efficiency is low. It takes 35 seconds to bite an liner, and the biting time is long. Summary of the invention

[0004] A new type of biting machine is developed for the newly developed inner liner. The present invention provides a multi-model dishwasher inner liner biting machine. The biting machine adopts a roller biting form from top to bottom. The roller can bite an inner liner when moving from the upper side to the lower side. The working cycle is only 18 seconds, which greatly improves the biting efficiency.
