Problems solved by technology

At this time, if the high-mixer starts unexpectedly, it will cause a major safety accident
However, the safety protection of the current high-mixer is very weak in this respect. A travel switch is interlocked with the control circuit to ensure that the high-mixer cannot be started when the cover is opened.
However, in actual use, the travel switch of the high-mixer is easily pressed by foreign objects, which cannot provide protection
At the same time, the high-mixer needs to open the cover frequently, and the travel switch is easily damaged, so the service life of the travel switch is not long
When there is a problem with the control program, there is a risk of abnormal startup of the high-mixer that cuts off the control circuit, causing injury to the operator
Therefore, the way of using travel switch to control circuit chaining has low reliability and low safety factor

Embodiment 1

[0031] Such as figure 1 As shown in the safety protection device of a high-speed mixer, the high-speed mixer includes a cover 1, a cover opening cylinder for opening the cover 2, an air source matched with the cover opening cylinder, and a power motor 3 for providing power. The cylinder 2 is connected with a solenoid valve 4; the safety protection device includes a gas circuit lock mechanism 5, a circuit breaker lock mechanism 6 and an eccentric key 7, and the cover opening cylinder 2 and the solenoid valve 4 are both connected with the gas circuit lock mechanism 5; The circuit breaker lock mechanism 6 is serially connected to the power motor 3; the eccentric key 7 is alternately connected with the air circuit lock mechanism 5 and the circuit breaker lock mechanism 6 in cooperation.

[0032] Specifically, the pneumatic lock mechanism 5 includes a mechanical valve 501, a base 502, a holder 503, a first cover 504, a first guide rod 505, a slider 506, a first spring 507, a stop 508, ...

Embodiment 2

[0044] The safety protection device of the high-speed mixer is the same as that of Embodiment 1 except for the following technical features: As a preference, the sliding block 506 includes a first sliding block 5061 and a second sliding block 5062, the first sliding block 5061 Both ends are provided with sliding holes through which the first guide rod 505 passes. The first sliding block 5061 and the second sliding block 5062 are integrally formed, and the first sliding block 5061 and the second sliding block 5062 are connected together. Type T. By adopting this design, it is very convenient to process the slider parts, and the processing cost is also reduced.

Abstract

The invention discloses a safety protection device of a high-speed mixer. The high-speed mixer is provided with a cover, an uncovering cylinder for opening the cover, an air source matched with the uncovering cylinder and a power motor for providing power, wherein the uncovering cylinder is connected with an electromagnetic valve; and the safety protection device comprises a gas path lock mechanism, a breaker lock mechanism and an eccentric key, wherein the uncovering cylinder and the electromagnetic valve are connected with the gas path lock mechanism; the breaker lock mechanism is connected to the power motor in series; and the eccentric key is alternatively matched and connected with the gas path lock mechanism and the breaker lock mechanism. The safety protection device of the high-speed mixer can prevent a worker from starting the high-speed mixer due to faulty operation, prevent potential safety hazards and improve the safety.

Description

Technical field [0001] The invention relates to a protection device, in particular to a safety protection device for a high-mixer. Background technique [0002] High mixer is an indispensable equipment in plastics, chemical, food and other industries, and it is widely used. High mixer is a kind of equipment for high-speed mixing and mixing of raw materials. During the use of high mixer, the operator needs to open the cover of the mixing tank of the high mixer to clean the cylinder and the stirring blade. At this time, if the high-speed mixer starts accidentally, it will cause a major safety accident. However, the current high-speed mixers have very weak safety protection in this regard. A travel switch is used to interlock with the control circuit to ensure that the high-speed mixers cannot start when the lid is opened. However, in actual use, the limit switch of the high-speed mixer is easily pressed by foreign objects and cannot provide protection. At the same time, the high...
