Self-adaptive adjusting device for extrusion roller

A fixing body is fixedly connected with a mechanical main body, a roller shaft is fixed in the fixing body, the two ends of the extrusion roller are fixed through the fixing body, horizontal rolling of the extrusion roller is achieved, an adjusting body is arranged on the fixing body, and when the extrusion roller is subjected to external force, the adjusting body can flexibly release the external force, so that the extrusion roller is prevented from being damaged. The roller shaft is prevented from being damaged by external force, the safety of the extrusion roller is protected, and the service life of the extrusion roller is prolonged; the adjusting body comprises a guide groove and an elastic buffer body, when the extrusion roller is subjected to external force, the roller shaft moves along the guide groove to flexibly release the external force, and the extrusion roller returns to the original position under the action of self weight to normally operate; the elastic buffer body elastically deforms to flex
