Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
The pretensioning device of a novel plasticizing unit, as shown in fig. 1, is the most preferred embodiment of the present invention. Including a left key, a right key, and a guide key 3.
The left key is attached to the end face of the right key, the left key is divided into two symmetrical left half rings 1, and half ring connecting screw holes 2 are formed in the positions, corresponding to the separating surfaces, of the two left half rings 1. And the two left semi-rings 1 are fixedly connected in the semi-ring connecting screw holes 2 through semi-ring connecting bolts. The direction of the semi-ring connecting screw hole 2 is vertical to the semi-ring cutting direction, so that the two semi-rings corresponding to the keys can be stably locked and fixed in a stress balance mode.
The right key is also divided into two symmetrical right semi-rings 4 corresponding to the left key, and semi-ring connecting screw holes 2 are formed in the positions, corresponding to the separation surfaces, of the two right semi-rings 4. And two right semi-rings 4 are fixedly connected in the semi-ring connecting screw holes 2 through semi-ring connecting bolts. Similarly, the direction of the semi-ring connecting screw hole 2 on the right key is also vertical to the semi-ring dividing direction, so that the two semi-rings of the corresponding key can be stably locked and fixed in a force balance manner.
Every left semi-ring 1 corresponds respectively and laminates with right semi-ring 4, and the binding face is inclined plane 6, and the angle 4 of inclined plane 6 between left key and the right key. The left half ring 1 is provided with a guide key 3 in a protruding mode, and the right half ring 4 is provided with a guide groove 5 corresponding to the position of the guide key 3. The guide key 3 is locked and fixed on the inclined surface 6 of the left half ring 1 through a screw. The guide keys 3 and the guide grooves 5 are distributed on the central line of the half rings. The slant of the inclined plane 6 is also consistent with the inserting direction of the key slot, that is, in the embodiment, the inclined plane 6 is obliquely directed from the outer edge of the half ring to the joint of two half rings in the same key. And the inclined planes 6 of the two semi-rings in the same key are correspondingly and symmetrically arranged.
