Detailed ways

As shown in Figure 1, the feeding device is installed on one side of the cartoning machine 10, and the two are connected through the conveying platform 8. The platform 8 sends the ointment patch packaging bag 11 to the cartoning machine 10 for box packing. As shown in Figure 4, the feeding device of the existing cartoning machine generally adopts the swing rod type suction and discharge feeding, that is, the swing rod sucks the material from the silo, and then sends it to the top of the conveying platform to discharge the material, and then swings back to absorb the material , This kind of structure adopts the swing rod, and the back swing takes up half of the feeding time, and the efficiency is very low.

For this reason, the utility model innovatively provides a kind of high-efficiency rotary sucking and releasing feeding device, as shown in Figure 1 and 2, this device comprises frame 2, and left and right turntables 3, rotatably installed on frame 2, 31. A suction rod 5 is rotatably installed between the left and right turntables 3, 31. Driven by the drive mechanism, the left and right turntables 3, 31 and the suction rod 5 can rotate respectively. Since the suction rod 5 is installed on the left and right turntables 3, 31, therefore, in addition to being able to rotate around the axis of the left and right turntables 3 and 31, the suction rod 5 can also rotate by itself, and the suction nozzle 6 installed on the suction rod 5 also moves with the suction rod 5; The rotation of the axis of the left and right turntables 3 and 31 is to drive the suction nozzle 6 to feed materials back and forth between the silo 1 and the conveying platform 8, and the rotation of the suction rod 5 is to allow the suction nozzle 6 to positively suck the ointment package in the hopper 1 Bag 11, because the silo 1 for storing the ointment paste packaging bag 11 is elongated, it has a certain angle with the conveying platform 8, in order to allow the ointment paste packaging bag 11 to slide down better and to take into account that the silo can be packaged with the ointment paste The equipment is connected to realize the linkage production. The angle here is generally set at about 45°, so that when the left and right turntables 3 and 31 reach the adsorption position with the suction rod 6, and with the rotation of the suction rod 5, the suction nozzle 6 can absorb the ointment in front Packaging bag 11, left and right turntables 3,31 cooperate with suction rod 5 to rotate just this meaning.

Take three suction rods and three suction nozzles on one suction rod as an example: the three suction rods 5 are evenly installed between the left and right turntables 3 and 31 along the circumference. At this time, the three suction nozzles 6 on the suction rod 5 are facing the conveying platform 8 due to the rotation of the suction rod 5, and are ready to discharge; The three suction nozzles 6 on the rod 5 are also facing the ointment paste packaging bag 11 placed obliquely in the feed bin 1 due to the rotation of the suction rod 5, and are ready to suck materials; the third suction rod 5 is in the feeding process; When starting, the left and right turntables 3, 31 rotate, and the suction nozzles 6 on the three suction rods 5 and the suction rod 5 can work in rotation. Compared with the single swing arm feeding method, this multi-suction rod rotary feeding method saves the time of swinging back and forth, greatly improving the feeding efficiency. Combined with the platform silo 7 below, it can feed continuous high-speed packaging machines. The matching degree of the feeding device is further improved. What needs to be mentioned is that the suction rod 5 can be one, and it can be assembled on a cartoning machine with low efficiency requirements; it can also be multiple, and it can be assembled on a large cartoning machine that requires high production efficiency; Generally, it is most reasonable to set three, which can basically meet the high-efficiency production requirements of existing ordinary cartoning machines.

As shown in Figure 2, the drive mechanism includes a motor 16 and a rotating shaft 14 connected to the motor 16. The rotating shaft 14 is mounted on the frame 2 through a rotating base 17, wherein the left turntable 3 is fixedly mounted on the rotating shaft 14. , when the rotating shaft 14 rotates with the left turntable 3, the suction rod 5 and the right turntable 31 also rotate accordingly, so that the suction rod 5 can rotate around the axes of the left and right turntables 3, 31; in order to allow the suction rod 5 Rotation gets up, on the rotating shaft 14 is also fixedly installed with the central gear 19, the outer planetary gear 21 is installed on the left end of the suction rod 5, and the intermediate planetary gear 20 is installed between the outer planetary gear 21 and the central gear 19, and the intermediate planetary gear 20 respectively Mesh with the central gear 19 and the outer planetary gear 21, wherein the intermediate planetary gear 20 is rotatably installed on the left turntable through the intermediate planetary gear shaft 201, and the outer planetary gear 21 is fixedly connected with the suction rod 5 through the outer planetary gear shaft 210; The left turntable 3 rotates, the middle planetary gear 20 rotates around the central gear 19, the middle planetary gear 20 rotates, and drives the outer planetary gear 21 to rotate, so that the suction rod 5 (rotatably mounted on the left turntable 3 through a bearing) can rotate automatically ; By adjusting the size of each gear, when the suction nozzle 6 is rotated to the position of the feed bin 1, it is just facing the ointment paste packaging bag 11, thereby the ointment paste packaging bag 11 is sucked out from the feed bin 1 smoothly.

The suction nozzle 6 is provided with a vacuum generated by the vacuum pump 9 to provide an air source. The vacuum pump 9 communicates with an external rotary air supply source 13. The suction and release of the suction nozzle 6 is also controlled by the rotary air supply source 13. When the photoelectric eye detects the suction When the nozzle 6 reaches the conveying platform 8, the air supply source 13 is controlled to stop the air supply, thereby realizing discharging; when the photoelectric eye detects that the suction nozzle 6 reaches the bin 1, the air supply source 13 is controlled to supply air, thereby realizing material suction. All are existing technologies, and will not be repeated here. The rotating air supply source 13 is installed on the rotating shaft 14, and the rotating shaft 14 has a hollow 15 in the center of the shaft. The rotating air supply source 13 communicates with the air nozzle 6 through the hollow 15 through the leather tube (so that the structure is more compact), and the general suction rod 5 is provided with a plurality of suction nozzles 6, in order to make a plurality of suction nozzles 6 work simultaneously, the suction rod 5 of the present utility model is provided with an axial cavity 50, each suction nozzle 6 communicates with the axial cavity 50, and the skin The pipe communicates with the axial cavity 50 of the suction rod 5 through the joint 22 .
