Clearance adjusting mechanism for master rotors of double roller drier

Abstract

Abstract The invention discloses a main drum clearance adjusting mechanism of a double-drum drier, comprising bearing seats, drum fixing seats and bearing seat displacing devices arranged at both ends of a driven main drum, wherein each drum fixing seat is provided with a bearing seat support platform, and the bearing seat is fixedly connected with the bearing seat support platform; the bearing seat displacing device is detachably and fixedly connected with a side face of the bearing seat, and cooperates with the drum fixing seat to form a screw pair for driving the bearing seat to move along the direction close to or away from the master driving main drum; the adjusting mechanism also comprises bearing seat slip structures, each of which is arranged on relative slip surfaces of the bearing seat and the bearing seat support platform, with a clearance formed between the lower end face of the bearing seat and the bearing seat support platform; and the bearing seat is driven by the bearing seat displacing device to move along the bearing seat slip structure. According to the invention, through the bearing seat slip structure between the bearing seat and the bearing seat support platform, precise and quick adjustment of the clearance between the two main drums is achieved, and the clearance adjusting efficiency and safe operation performance of the main drums are improved.

Description

technical field [0001] The invention relates to the technical field of drum drying, in particular to a main drum gap adjustment mechanism of a double drum dryer, which is used for adjusting the gap between two main drums. Background technique [0002] The drum dryer is the most critical equipment in the field of food drying technology. According to the different drum drying forms, it can be divided into: single drum type and double drum type. The double drum is divided into the main drum with auxiliary drum and the main drum without auxiliary drum. The double-drum dryer has technical advantages different from the single-drum dryer. It can not only save floor space, but also save transmission power. The double-drum dryer drives the main drive main drum 1 to rotate through the main drive gear 3 through a single frequency-adjustable motor. The main drive main drum 1 is meshed with the driven main drum 2 by using a large gear to realize the operation of the driven main drum 2. ...

Problems solved by technology

The lower end surface of the support in the above-mentioned patent documents is completely in contact with the chute. Therefore, the force required to push the support by rotating the lead screw is relatively large. This structure is only used for gap adjustment between light rollers with light weight. If this kind of adjustment mechanism is used to adjust the gap between the two main rollers in the double roller, since the force bearing surface is larger and the weight of the roller is heavier, a larger force is required to push the bearing seat to move, and a larger tightening force is required. It will also damage the lead screw
