Jacking device for deposition line of balance ring of washing machine

Abstract

A washing machine balance ring deposition line jacking device comprises a connecting plate, a gradient adjusting plate, an air cylinder, an ejector rod, a rolling wheel and a guide rail. The connecting plate is fixed to the rack, a guide rail is arranged below the gradient adjusting plate, an air cylinder is arranged at one end of the gradient adjusting plate, and the gradient adjusting plate can slide along the guide rail under the action of the air cylinder. An ejector rod is arranged at the upper part of the connecting plate, a roller is arranged below the ejector rod, and a rubber jacking disc is arranged above the ejector rod; when the air cylinder pushes the gradient adjusting plate to slide, due to the fact that the gradient adjusting plate fluctuates up and down, the ejector rod moves in the vertical direction when passing through the position below the rolling wheels, and the deposited part is ejected away from the mold and taken out.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of production line of washing machine, in particular to a lifting device for a washing machine balance ring welding line. BACKGROUND

[0002] When the washing machine is dehydrated, the motor rotates at high speed, and the clothes in the washing machine are not evenly placed, which will produce strong vibration and noise. In the production process of the washing machine, salt water needs to be injected into the balance ring to offset the resonance generated by the washing machine. The balance ring is formed by heating and welding the upper and lower half ring-shaped plastic parts into a whole. During the welding, first, the upper and lower half ring-shaped plastic parts are placed in the heating mold, and the heating plate is pressed on the plastic parts for heating. When the outer opening of the plastic parts is in a molten state, the heating plate is removed, and the upper and lower plastic parts are pressed together. After cooling and forming, it is taken out of the mold. When taking out the plastic parts, since the plastic parts expand after heating, they are stuck in the mold. Either a long time is waited until they shrink after cooling, or artificial knocking is used to take them out. The waiting time is too long, which affects the production line rhythm. Artificial knocking easily damages the plastic parts, which affects the product yield. In view of the deficiencies of the prior art, the present application provides a washing machine balance ring welding line lifting device to solve the problems in the background art. SUMMARY

[0003] To achieve the above purpose, the present application is realized by the following technical scheme: a washing machine balance ring welding line lifting device, comprising a connecting plate, a slope adjusting plate, a gas cylinder, a lifting rod, a roller and a guide rail.

[0004] The connecting plate is fixed on the rack, the slope adjusting plate passes through the connecting plate, the slope adjusting plate is provided below the guide rail, and one end is provided with a gas cylinder. Under the action of the gas cylinder, the slope adjusting plate can slide along the guide rail. The upper part of the connecting plate is provided with a lifting rod, the lower part of the lifting rod is provided with a roller, and the upper part is provided with a rubber lifting disc. When the gas cylinder pushes the slope adjusting plate to slide, the slope adjusting plate has ups and downs, passes through the lower part of the roller, and the lifting rod moves in the vertical direction to lift the welding part away from the mold and take it out.

[0005] The slope adjusting plate is designed to be detachable, which can be replaced according to different models of balance ring to achieve good lifting effect.

[0006] The upper part of the lifting rod is provided with a rubber lifting disc, which is wide and increases the contact area with the plastic part, effectively protecting the plastic part from being damaged by the lifting rod. BRIEF DESCRIPTION OF DRAWINGS

[0007] Figure 1 It is an external structure of the present application;

[0008] In the figure: 1, rubber lifting disc; 2, lifting rod A; 3, lifting rod B; 4, roller; 5, guide rail; 6, slope adjusting plate; 7, connecting plate; 8, gas cylinder. DETAILED DESCRIPTION

[0009] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0010] First, the upper and lower half annular plastic parts are put into the heating mold, and the heating plate is pressed on the plastic parts for heating. When the outer opening of the plastic parts is in a molten state, the heating plate is removed, and the upper and lower plastic parts are pressed together. After cooling and forming, the air cylinder is started, and the air cylinder pushes the slope adjusting plate. The slope adjusting plate moves horizontally along the track. When the convex of the adjusting plate passes the top rod A, the top rod A is displaced upward, and the rubber lifting disc opens one side of the balance ring plastic part. When the convex of the adjusting plate passes the top rod B, the top rod B is displaced upward, and the rubber lifting disc opens the other side of the balance ring plastic part, so that it is completely separated from the heating mold. After being taken out, the new workpiece is continuously put in for welding.

[0011] The above describes one embodiment of the present application in detail, but the described content is only the preferred embodiment of the present application, and cannot be considered as limiting the implementation scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the patent coverage scope of the present application.
