Description

(54) GUIDING FUN TO AUTOMATIC MACHINE

FOR PRODUCTION OF GLASS BALLS The guide funnel is made in the form of three guide cones 7, the axis of two of THEM; the extreme ones are located in the plane 8, which lies at an angle of 75 to the base of the cones, and the axis of the middle axis is located in the plane 9, which lies at an angle of 105 ° to the base of the cones. The scissor slider 2 receives a reciprocating movement from the pneumatic actuator, and at half of its stroke, both when moving to the left and when moving to the right, the slider stops. Such stops are necessary for receiving a jet of glass melt by a receiving funnel 1 before cutting off its preform. In one cycle of movement of the slider 2, four blanks are cut: two by the extreme openings of the knife and two by the middle holes. The guide cones 7 direct the billet glass to the guide trays 4, from where it falls alternately into four pairs of rolling drums 5. The cut blanks, falling between the rolling drums 5, cut into balls and move from center to edge, into trays and roll to the screw 6. Object of the invention The guide funnel to the automatic machine for the production of glass balls, which contains three cones mounted on the plate base, characterized in that, in order to improve the quality of the balls and increase the service life of the funnel, The new cones are set at an angle of 72-78 ° to the base, and the middle one is at an angle of 102-108 °.
