Four shower nozzles 905 are rectangle diagonal distribution, and four the incline direction of shower nozzle 905 is along clockwise arrangement, because the bustle pipe 902 can rotate under the effect of bearing 901, the effort that produces when spraying rivers through shower nozzle 905 can promote the bustle pipe 902 and rotate to make bustle pipe 902 let shower nozzle 905 carry out comprehensive washing clearance to the raw materials piece in the rotation in-process.
The working principle of the invention is as follows: firstly, by starting the first driving motor 601, the first driving motor 601 can drive the wheel disc 602 to rotate, so that the wheel disc 602 can squeeze the moving block 605 through the first roller seat 606 in the periodical rotation process, the moving block 605 compresses the supporting spring 604, the moving block 605 is contracted into the opening 603, the knurling rod 608 is driven to perform periodical transverse reciprocating motion, the knurling rod 608 can perform intermittent knurling squeezing on the raw material piece, and large cutting heat and internal stress generated in the rolling process of the raw material piece can be avoided.
Then, when the wheel disc 602 slides in the grooves 701 through the second roller seat 704 in the periodical rotation process to squeeze the air bag 702, the moving block 605 can be driven to move towards the wheel disc 602 through the connecting rod 707, so that the first roller seat 606 on the moving block 605 contacts with the outer contour of the side wall of the wheel disc 602, the knurling rod 608 squeezes the raw material piece, meanwhile, the air flow in the air bag 702 can enter the water tank 802 through the air pipe 801, along with the enhancement of the air pressure in the water tank 802, the water flow can be discharged into the water bag 809 through the water suction pipe 810 under the action of the air pressure, and as the sliding plate 806 can move on the fixed rod 805 through the sliding hole 807, the sliding plate 806 can be driven to move downwards on the fixed rod 805 along with the volume expansion of the water bag 809, so as to stretch the tightening spring 808, and when the air pressure disappears, the water flow in the water bag 809 can be squeezed into the water pipe 814 through the water pipe 812, so that the water flow discharged from the water pipe 814 cools the raw material piece.
Finally, by utilizing the comprehensive cleaning assembly 9, the annular pipe 902 can rotate under the action of the bearing 901, and the acting force generated when water flows are sprayed through the spray head 905 can push the annular pipe 902 to rotate, so that the spray head 905 can comprehensively wash and clean the raw material pieces in the rotation process of the annular pipe 902.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
