Description
Technical Field
The embodiment of the application relates to the field of machinery, in particular to an ejecting roller device.
Background
As shown in fig. 1, in the current belt digital printing machine, a drive roller rolls through a conduction band to drive a driven roller, the conduction band needs to be tensioned during printing, so that the conduction band generates inward tension on the drive roller and the driven roller, the roller, i.e. the drive roller or the driven roller, resists the tension of the conduction band only by the rigidity of the roller, and the roller is easily deformed due to uncontrollable rigidity of the roller due to material reasons, so that the conduction band is inconsistent in movement. In order to prevent the roller from deforming due to insufficient rigidity, a device which can generate an outward force to the middle of the roller to offset the pulling force is arranged, and the device is called a top roller device.
At present, the double rollers are adopted in the top roller device in the industry to prop against the rollers in a fan shape, and the rollers can deform in different degrees, so that the existing top roller device is a fixed structural part, and the roller abrasion is serious due to the fact that the pressure between the top roller device and the rollers is too large.

In a general operating condition, as shown in fig. 2, the first direction may be referred to as a front-back direction, the second direction may be referred to as a top-bottom direction, the roller axis direction may be referred to as a left-right direction, and the specific placing direction may be determined according to actual needs, and is not limited herein.
