The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a coating machine coating station compression roller interval fine-tuning installs in the wallboard outside of coating machine, including installing the eccentric wheel on coating machine compression roller outer end, be fixed with the base on the wallboard, the slip is equipped with the nut that has the inclined plane on the base, and the nut rotates and is connected with the lead screw, the eccentric wheel on rotate and install deep groove ball bearing, the last inclined plane contact of deep groove ball bearing and nut.
Specifically speaking, the body of eccentric wheel in seted up the inner chamber, deep groove ball bearing passes through the commentaries on classics round pin and rotates and establish in the inner chamber.
For the convenience rotates the lead screw, the wallboard on be fixed with a pair of rotation at a distance and support the rolling bearing of lead screw, lead screw front end and nut normal running fit, lead screw rear end rigid coupling has the hand wheel.
Furthermore, a guide plate is fixed on the base, a guide groove is arranged on the guide plate, the lower end surface of the nut is embedded into the guide groove and is in sliding fit with the guide groove,
in order to reduce the friction resistance between the nut and the guide groove, the lower end face of the nut is provided with a rectangular groove, and bulges on two sides of the rectangular groove are in sliding fit with the inner bottom surface of the guide groove.
The two corner ends of the inner bottom surface of the guide groove are provided with oblique corner grooves so as to eliminate the motion interference phenomenon and improve the motion smoothness.
The utility model has the advantages that: the utility model discloses installation deep groove ball bearing on the eccentric wheel, the last inclined plane through the nut promotes the lift of deep groove ball bearing, and then realizes the regulation of compression roller interval through the eccentric wheel effect, can not produce the friction damage to the eccentric wheel, and reducible area of contact with the nut makes the regulation more steady, adjusts the precision and must improve.
Drawings
