The invention discloses a rotating shaft with controllable rotation resistance and application thereof, and belongs to the field of machinery. The rotating shaft comprises a main shaft, wherein a rotating shaft transmission chain wheel, an anti-explosion box driving chain wheel, an electromagnetic clutch coil, a clutch rotor and a friction disc assembly are arranged on the main shaft; the friction disc assembly comprises a friction disc body and a clutch armature; clamping armatures which stand on the two sides of the friction disc body and have friction pieces are arranged on the friction disc body; the clamping armatures are fixed through brackets; the rotating shaft transmission chain wheel, the anti-explosion box driving chain wheel and the clutch rotor are fixed to the main shaft; and the electromagnetic clutch coil and the friction disc assembly are connected with the main shaft through bearings. According to the rotating shaft, an electromagnetic clutch transmits rotation resistance of the rotating shaft, the actuation time is short, the reliability is good, the rotating shaft is applicable to long-term and frequent operation, stable operation resistance is provided, the adjusting method is simple, the effect is obvious, and the requirements that the bagging length of an edible fungus bagging machine is uniform and stable, the tightness adjustment range is wide, and the tightness of a whole bag is uniform are met.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a rotating shaft with controllable rotation resistance and its application. Background technique [0002] The rotational speed of the rotating shaft is given by the prime mover through the transmission device, and the rotating shaft obtains the required rotational speed to complete the processing command or transmit the rotation to other shafts. This is a common theory in mechanical design and there are countless examples. [0003] However, when the rotating shaft does not change the rotating speed through the prime mover and the transmission device, the resistance to the rotation of the shaft must be increased in a short period of time. This resistance does not hurt the prime mover and the transmission device, and is extremely suitable for production needs. [0004] For example: the first step in the production of edible fungi is to pack the edible fungus culture medium, that is, fine woo...

Problems solved by technology

[0006] However, the specially designed orbital friction mechanism will occupy the three-dimensional and plane space of the machine, and the design is complicated

Although this special mechanism can help the explosion-proof box to provide resistance during the bagging stage, it takes a long time for the contact, compression and separation process of the friction pair, and it is not suitable for the frequent actions of the bagging machine (running once every three seconds) , about 5,000-10,000 times per day), after long-term operation, the tightness of each fastening screw of the mechanism changes, the amount of air return between contact parts and the wear of each contact surface increase, which seriously affects the degree of adhesion, and each hinge The gap between the pin shafts increases, and these factors will cause unreliable action and unstable performance of the mechanism, resulting in inconsistent tightness of bagging

Therefore, the adjustment effect of the mechanical friction structure is not obvious.

[0007] Using the anti-torque of the DC motor to provide the adjustment device for the application resistance can meet the requirements of reliable and agile action in terms of electric control on-off, but after a long time of work, affected by various control parameters and environmental factors, it often causes bagging tightness.
