Working method and principle: molding dixie cup on paper cup molding, successively from the discharging work of paper cup molding discharge port plate 3
Position is entered tubular dixie cup by tubular cup support 5 after dixie cup ejection and is collected in head 6 by cylinder ejector, and dixie cup is up big and down small
Cone cylinder shape, the minimum diameter enclosed between multiple elastic spacing pieces 10 is less than the maximum gauge of dixie cup and is greater than the minimum of dixie cup
Diameter, multiple elastic spacing pieces 10, which are extruded, when dixie cup is by tubular cup support 5 is flared out, and dixie cup enters tubular paper
After cup is collected in head 6, multiple elastic spacing pieces 10 reset, and block dixie cup, so that dixie cup will not be fallen after rise, multiple elastic spacing pieces 10
Movable end a part is located at tubular dixie cup and collects in head 6, and dixie cup is located at tubular dixie cup in ejection rear portion and collects in head 6, and
Below the air inlet that tubular dixie cup collects head 6.
Air inlet pipe 11, which tilts upward the wind that blower 7 is blown out in 45° angle, to be sent in tubular dixie cup collection head 6, is then passed through
It is discharged after crossing transmission pipeline 12,8 interlude of dixie cup collection frame is the framework of hollow out, and framework is enclosed by multiple columns, is passed through
Wind after transmission pipeline 12 is discharged from interlude hollow part, and wind generates the air-flow of flowing when passing through, and is located at tubular dixie cup
Collect head 6 in dixie cup be drawn into transmission pipeline 12 by air-flow, when dixie cup by tubular dixie cup collect head 6 air inlet after,
Dixie cup is rapidly feeding by the wind that blower 7 is blown out into dixie cup collection frame 8, and dixie cup is successively buckled to and drops into dixie cup collection frame 8, and
It is stacked into tubular, dixie cup discharge flapper 16 is located at below 8 discharge port of dixie cup collection frame under default situations, blocks dixie cup.
Proximity sensor 40 detects the quantity for entering dixie cup in dixie cup collection frame 8, and signal is given to PLC controller,
Counter is equipped in PLC controller, after reaching specified quantity, PLC controller controls round tube push-pull electromagnet 17 and starts, circle
17 moment of pipe push-pull electromagnet closes after opening, and round tube push-pull electromagnet 17 pulls downward on 45 one end of L shape swing arm, L shape
45 other end of swing arm pulls back connecting rod 46, and connecting rod 46 drives swing rod 20 to swing, and dixie cup discharge flapper 16 follows swing rod 20 to one
Side oscillation, 8 discharge port of dixie cup collection frame is in the open state, and dixie cup cylinder, which drops into, to be turned in elbow 18, then curved by turning to
First 18 fall on staged slide carriage 32, and dixie cup discharge flapper 16 is inserted on inclined guide plate 22 after opening, and pass through guide plate 22
The frictional force generated with dixie cup discharge flapper 16 makes dixie cup discharge flapper 16 block a period of time, and dixie cup discharge flapper 16 is in swing rod
20 and 15 hinged place of cabinet reduction torsion spring reaction force under reset, according to 7 wind-force of the length of transmission pipeline 12 and blower
Size calculates the time that single dixie cup is fallen into dixie cup collection frame 8, is carried out by position of the adjusting nut 23 to guide plate 22
Fine tuning, to adjust the size of 16 frictional force of guide plate 22 and dixie cup discharge flapper, frictional force is bigger, and dixie cup discharge flapper 16 pauses
Time it is longer, the dixie cup cylinder that the time of pause is maintained in dixie cup collection frame 8 can be fully contemplated to turn to elbow 18 in, together
When next group from discharge port plate 3 come out dixie cup do not fall within also into dixie cup collection frame 8, turn to elbow 18 bending segment on the inside of barrel
For opening, prevent dixie cup cylinder from blocking in steering elbow 18.
Dixie cup cylinder enters in lower material frame 30, and damping sponge layer is equipped on the inside of limit plate 35, prevents dixie cup cylinder in inertia
Effect is lower and the collision of lower 30 side wall of material frame causes to deform, while a pair of of limit plate 35 corrects the position of dixie cup cylinder, blanking
Frame angle degree adjusting screw rod adjusts the tilt angle of lower material frame 30, and dixie cup cylinder can roll after falling on staged slide carriage 32 to lower one end
It falls, dixie cup cylinder slows down in ladder-like falling process to tumbling speed, while correcting to position and direction, dixie cup cylinder
Dropping into preferably can stop a period of time by flapper 33, so that the direction of dixie cup cylinder and lower 30 keeping parallelism of material frame, then
Flapper 33 is pushed open under the action of dixie cup cylinder own wt, and dixie cup cylinder drops into packing case, lower 30 discharge port position of material frame
Above the position of packing case middle, after dixie cup cylinder enters packing case, can voluntarily it be rolled to lower, realization is voluntarily piled up.
