Automatic overturning device

Abstract

The invention relates to an automatic overturning device. The automatic overturning device comprises a shell formed by connecting a base and a cover, wherein the shell is internally provided with a driving mechanism and a rotary shaft; the driving mechanism and the rotary shaft are connected with each other by a connection shaft sleeve; the tail end of the rotary shaft is sleeved with a connection piece for mounting an overturning piece; the rotary shaft is further provided with a bearing and a fixed shaft sleeve; the fixed shaft sleeve is internally provided with a torsion spring; the driving mechanism is further connected with a control system. The automatic overturning device is reasonable in structural design and low in cost; the driving mechanism drives the rotary shaft to rotate and the rotary shaft can rotate stably to drive the connection piece and the rotary piece to overturn so as to automatically open or close the overturning piece; the transmission is very stable and noises are very low; when the driving mechanism is abnormal and does not work or when the overturning piece is closed to meet a counter force or when any one torsion spring loses efficacy, the device can prevent accidents by automatically adopting corresponding measures, so that the use safety performance of the device is greatly improved, and the market competitiveness and the brand image of enterprises are also greatly improved.

Description

technical field

[0001] The invention relates to an automatic turning device in the field of industrial control automation. Background technique

[0002] With the development of science and technology, people have higher and higher demands on the degree of automation of electrical appliances used in daily life. These include household appliances, automobiles, etc. Most of these products have flip parts (such as lids or doors). In order to realize the automatic opening and closing function of the flip parts, many manufacturers are working hard to develop corresponding product mechanisms. The mechanism has the following problems: 1. Most of the existing overturning mechanisms use a motor to directly drive the overturning part to overturn, which requires a very large power of the motor. Noise will be generated when the high-power motor works, and the cost of the system will be increased simultaneously; and the overturning part is overturned The moment of rotation does not chang...
