BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The utility model is further described below in conjunction with the accompanying drawings.

[0010] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] The utility model is described in detail below in conjunction with specific implementation methods:

[0012] like Figure 1 The device for screening the roundness size of aluminum-plastic caps for medicine bottles shown in the figure comprises a feeding platform 1, a screening frame 2, a transmission platform 3, a telescopic rod 31, a telescopic cylinder 4, a rack 5 and a pressing plate 6, wherein the screening frame 2 is fixedly mounted on the feeding platform 1, and the screening frame 2 is arranged to be installed in the middle of the feeding platform 1, and the feeding platform 1 has a feeding channel, and a baffle 12 is fixedly arranged on the outer side of the feeding channel, and a through hole is provided in the middle of the feeding channel, and the screening frame 2 is located in the through hole in the middle of the feeding channel, and the top surface height of the screening frame 2 is lower than the top surface height of the feeding channel, and unqualified product channels 21 are provided on both sides of the screening frame 2, and a qualified product channel 22 is provided in the middle of the screening frame 2, and the inner side surface of the feeding platform 1 has an arc-shaped concave Mouth 11, the arc-shaped recess 11 is located just above the qualified product channel 22, the two ends of the telescopic rod 31 are respectively fixedly connected to the screening frame 2 and the transmission platform 3, the cylinder body of the telescopic cylinder 4 is fixedly mounted on the transmission platform 3, the piston rod of the telescopic cylinder 4 is fixedly connected to the screening frame 2, a driving motor is fixedly mounted on the transmission platform 3, a gear is also rotatably mounted in the transmission platform 3, the rack 5 is slidably mounted on the transmission platform 3, the rack 5 is meshed and transmission-connected with the gear, the central axis of the gear is transmission-connected with the output shaft of the driving motor, connecting plates 61 are fixedly mounted on both sides of the rack 5, the pressing plate 6 is fixedly mounted on the connecting plate 61, and the pressing plate 6 is located on the upper part of the top surface of the feeding channel.

[0013] The inner sides of the pressure plate 6 and the baffle plate 12 are both screwed and fixed with a hard rubber plate 7, and the outer plate surface of the hard rubber plate 7 is provided with a mesh anti-skid pattern, which is convenient for disassembly and replacement of the hard rubber plate 7 after it is worn. The mesh anti-skid pattern can increase the friction with the aluminum-plastic cover to prevent the aluminum-plastic cover 9 from falling downward under the action of its own gravity.

[0014] A screw sleeve is fixedly installed on the screening frame 2, and a stop bolt 32 is threadedly installed on the screw sleeve. Adjusting the stop bolt 32 can limit the extreme position of the transmission platform 3 approaching the screening frame 2, so as to avoid the aluminum-plastic cover 9 being compressed and deformed due to excessive stroke of the telescopic cylinder 4.

[0015] The feeding table 1 is provided with a positioning blind hole, in which a stop pin 8 can be inserted and installed. Inserting the stop pin 8 can limit the feeding limit position of the aluminum-plastic cover 9 in the feeding channel. During screening, the stop pin 8 is taken out from the positioning blind hole.

[0016] First, the aluminum-plastic cover 9 is loaded into the loading channel on one side of the loading platform 1. At this time, the pressing plate 6 does not contact the aluminum-plastic cover 9. The telescopic cylinder 4 is started to drive the transmission platform 3, the connecting plate 61 and the combination of the pressing plate 6 to approach the screening frame 2 until the pressing plate 6 is pressed against the aluminum-plastic cover 9. The aluminum-plastic cover 9 is pressed between the pressing plate 6 and the baffle 12 without deformation. The telescopic cylinder 4 stops running, and the drive motor is started to drive the rack 5 to reciprocate left and right through the gear. The pressing plate 6 moves left and right synchronously. When the pressing plate 6 moves, it drives the aluminum-plastic cover 9 to rotate. The rotation distance of the aluminum-plastic cover 9 to the qualified product channel 22 is greater than its own circumference, and the roundness size of the aluminum-plastic cover 9 When the standards are met, a gap appears between the aluminum-plastic cover 9 and the pressing plate 6 and the baffle 12, and the pressing plate 6 and the baffle 12 cannot press the aluminum-plastic cover 9, and the aluminum-plastic cover 9 will fall under its own weight. When the unqualified aluminum-plastic cover 9 is located in the unqualified product channel 21, it will directly fall into the unqualified product channel 21. When the unqualified aluminum-plastic cover 9 falls into the feeding channel, it will be pushed into the unqualified product channel 21 by the pushing action of the aluminum-plastic cover 9 behind. After all the aluminum-plastic covers 9 in the single-side feeding channel are screened, the telescopic cylinder 4 drives the pressing plate 6 to move outward and reset, and feeds the other feeding channel, and performs reciprocating screening operations in this way.
