DETAILED DESCRIPTION

[0026] ‌Dishwasher liner undercut‌ refers to a processing technique performed on the edge of the liner, which is usually used to enhance the strength and sealing of the liner. Specifically, undercutting is done by forming a certain depression or groove on the edge of the dishwasher liner to increase the strength and sealing performance of the edge. This process is very important in dishwasher manufacturing because it directly affects the service life and performance of the liner.

[0027] The present invention provides Figure 1-Figure 6 The dishwasher inner tank undercutting machine shown in the figure comprises a base 17, the upper surface of the base 17 is provided with a first side plate 1 and a second side plate 5, the first side plate 1 and the second side plate 5 are both fixedly connected to the upper surface of the base 17, and the first side plate 1 and the second side plate 5 are respectively provided with a supporting mechanism and an undercutting mechanism on the side close to each other; The supporting mechanism is used to support and fix the inner liner 4; The biting mechanism bit the inner circle or outer circle of the end of the inner liner 4; The biting mechanism is arranged to be movable relative to the supporting mechanism, and the biting mechanism is arranged to be rotatable along the central axis of the inner liner 4. When the biting mechanism moves, the distance between the biting mechanism and the supporting mechanism increases or decreases. The biting mechanism includes a biting plate 9, the inner and outer surfaces of the biting plate 9 are both provided with telescopic grooves 15, a biting block 10 is slidably provided in the telescopic groove 15, and the biting block 10 is pneumatically driven when sliding; The undercut plate 9 can be vertically moved toward the center line of the inner container 4 .

[0028] During operation, the inner liner 4 is tightened and fixed by the supporting mechanism, and the supporting mechanism is tightened and fixed at the inner circle of one end of the inner liner 4 .

[0029] Then adjust the height position of the bite plate 9. If it is necessary to bite the inner circle of the inner liner 4, adjust the bite plate 9 to the horizontal height position corresponding to the inner circle of the inner liner 4; if it is necessary to bite the outer circle of the inner liner 4, adjust the bite plate 9 to the horizontal height position corresponding to the outer circle of the inner liner 4.

[0030] Afterwards, the bite edge mechanism is moved until the bite edge plate 9 on the bite edge mechanism extends into the interior of the inner liner 4 or extends to a designated position of the outer circle of the bite edge plate 9 .

[0031] The position of the bite block 10 is subsequently adjusted so that the bite block 10 bites the inner ring or outer ring of the inner liner 4 in a press-fit manner to form a groove.

[0032] Finally, the biting mechanism is driven to rotate, and when the biting mechanism rotates, the biting block 10 is engaged with the inner circle or the outer circle of the inner liner 4 to form a circle of biting.

[0033] In the prior art, the bite edge block 10 is usually driven to move electrically to form a groove on the inner ring or outer ring of the inner liner 4. There is a problem of mechanical jitter when the electric method is initially started or shut down, which can easily cause the inner ring or outer ring of the inner liner 4 to be subjected to excessive force, resulting in cracks in the inner liner 4 or a slightly larger groove, affecting the bite edge quality.

[0034] Therefore, the present invention pneumatically drives the bite block 10 to move, controls the initial air intake to be relatively slow, can reduce or even eliminate the problem of mechanical shaking, ensures that the groove size formed by the bite is appropriate, the inner liner 4 is not easy to crack, and can be processed to form a bite edge with good quality.

[0035] It should be noted that the inner liner 4 may also be fixed using other common methods, not limited to the method disclosed in the present invention.

[0036] In the present invention, multiple groups of biting mechanisms are provided, and the multiple groups of biting mechanisms are distributed in a circular array, and can bite the inner liner 4 at multiple points simultaneously. The biting process is stable, the biting interfaces are aligned, and the left and right misalignment is ≤1mm.

[0037] In the present invention, a second electric cylinder 6 is arranged on the second side plate 5, and the second electric cylinder 6 is used to drive the biting mechanism to move and relatively approach or move away from the supporting mechanism; a connecting disk 21 is installed at one end of the second electric cylinder 6 away from the second side plate 5, and a motor 20 is installed on the surface of the connecting disk 21, and a turntable 7 is fixedly installed on the rotating shaft of the motor 20, and the biting mechanism is located on the turntable 7, and the motor 20 drives the turntable 7 to rotate, so as to drive the biting mechanism to rotate; when the biting mechanism rotates, the biting block 10 can be used to bite on the inner liner 4 to form a biting edge. It should be noted that the bitten edge position of the inner liner 4 should be heated to a state where it can be shaped.

[0038] In the present invention, a sliding groove 8 is provided on the turntable 7, and a biting plate 9 is slidably provided in the sliding groove 8. A third electric cylinder 22 for driving the biting plate 9 to move is provided in the sliding groove 8. The biting action is controlled by sliding the biting plate 9 along the sliding groove 8. The biting accuracy is high, and the qualified rate can reach 99.5%.

[0039] In the present invention, an air cavity 14 is provided inside the bite plate 9, and the air cavity 14 is connected with the telescopic groove 15. An inflation and suction pump 11 is installed on the turntable 7, and a hose 12 is provided on the inflation and suction pump 11, and the hose 12 is connected with the inside of the air cavity 14; a limit plate 16 is installed at one end of the bite block 10 located inside the air cavity 14, and a spring 23 is provided between the limit plate 16 and the inner wall of the air cavity 14, and the edge of the limit plate 16 is fixedly connected and sealed with the inner wall of the air cavity 14 by a rubber sleeve 25. When the inflation and suction pump 11 is started, the inflation and suction pump 11 can transport gas into the air cavity 14, and the gas pushes the bite block 10 to move outward. When the gas in the air cavity 14 is extracted, the bite block 10 is reset by the force of the rubber sleeve 25, so as to facilitate the control of the telescopic movement of the bite block 10.

[0040] Furthermore, a pressure sensor 13 is embedded and fixed on the surface of the bite block 10; according to the pressure monitored by the contact between the pressure sensor 13 and the inner liner 4, it can be judged whether the bite processing of the inner liner 4 is qualified. For example, when the value monitored by the pressure sensor 13 fluctuates, it proves that there are protrusions or depressions on the bite edge of the inner liner 4, indicating that it is unqualified, and the purpose of automatic detection can be achieved.

[0041] According to actual needs, the bite block 10 can be set to be rectangular, arc-shaped or wavy, so as to facilitate processing to form bites of different shapes.

[0042] According to actual needs, at least one undercut block 10 may be arranged along the horizontal direction of the undercut plate 9 so as to form a plurality of undercut grooves.

The plurality of first electric cylinders 3 are arranged at equal angles along the outer ring of the central axis 2, and the first electric cylinder 3 is fixedly mounted between the outer ring of the central axis 2. The inner liner 4 is detachably mounted on one end of the first electric cylinder 3 away from the central axis 2; when the first electric cylinder 3 is started, it can be tightened and fixed on the inner wall of the inner liner 4.

[0045] refer to Figure 7 As shown in the figure, in the present invention, side support frames 26 are installed on both sides of the base 17, and the sides of the two side support frames 26 close to each other are fixedly connected with electric cylinders 27, and the ends of the electric cylinders 27 are provided with electric heating plates 28. When working, the electric cylinders 27 are started, and the electric cylinders 27 can push the electric heating plates 28 to fit the outer circle of the inner liner 4, so that the biting position of the end of the inner liner 4 is heated, so that the inner liner 4 can be bitten.

[0046] Furthermore, the detachable connection between the electric heating plate 28 and the electric cylinder 27 in the present invention allows the electric heating plates 28 of different specifications to be replaced to match more models of inner tanks 4.
