Description

Technical Field

[0001] The utility model belongs to the technical field of industrial mixing, and in particular relates to a mixer. Background Art

[0002] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials and form particles. It completes the mixing, kneading, and pelletizing processes in the same device. It has few steps and is easy to operate. It can quickly and efficiently prepare the required particles in the shortest time.

[0003] The main components of the mixer include a barrel and a barrel cover. The barrel cover is used to control the opening and closing of the barrel to facilitate the addition of raw materials or the output of finished products. In order to facilitate the output of prepared particles, the barrel can be flipped to facilitate the pouring out of the finished product. During the opening and closing process of the barrel cover and the flipping process of the barrel, its movement is generally controlled by a cylinder, etc., and the movement position of the barrel cover or the barrel is detected by a photoelectric switch. When the photoelectric switch fails or the detection accuracy is low, there is a possibility that the barrel cover will collide with the barrel when closing, or the barrel does not stop in time when resetting, and the barrel will also collide with the frame, causing equipment damage, high maintenance costs, and even the risk of equipment scrapping; in addition, the equipment will shake during the operation of the mixer, which will also affect the closing state of the barrel cover. If the barrel cover is over-closed, it will also cause the seal between the barrel cover and the barrel to deform too much, and the rotation resistance of the barrel will be too large, affecting the mixing effect.
