[0046] Working principle:

[0047] The storage barrel containing benzotriazole particles is installed on one side of the utility model and the feed inlet of the particle discharge valve 37 is connected with the bottom of the storage barrel through a pipeline, so that the benzotriazole particles in the storage barrel can enter the inside of the particle discharge valve 37 through the pipeline; the gas inlet of the vacuumizing equipment is connected to the gas outlet joint 48; a certain number of can covers 10 are stacked in the cover falling device 43 with the openings of each cover falling device 43 facing upwards.

[0048] The first conveying line 73 in the can feeding assembly 7 is started to work and a plurality of empty packaging cans 9 are placed on the conveying belt of the first conveying line 73 with the openings facing upwards, so that each packaging can 9 is moved towards the support table 71, and then each packaging can 9 is moved to the top of the support table 71 and arranged between the two first blocking strips 72 in turn, so that one packaging can 9 closest to the circular box 21 in the rotating assembly 2 is moved to the first notch 211 and the outer wall is attached to the outer circumferential surface of the disc 22.

[0049] First, the telescopic end of the positioning cylinder 61 in the positioning assembly 6 is driven to shrink inward to drive the positioning block 62 away from the disc 22, and then the reduction motor 23 is started to rotate the rotating shaft, so that the disc 22 rotates in the circular box 21, when one of the arc-shaped grooves 221 moves to the inside of the first notch 211, the reduction motor 23 is turned off, so that one packaging can 9 closest to the circular box 21 is pressed into the above-mentioned arc-shaped groove 221, then the reduction motor 23 is started again to drive the disc 22 to continue rotating by a certain angle, until the adjacent arc-shaped groove 221 on the downstream side also moves to the inside of the first notch 211, then the reduction motor 23 is turned off and then started again according to the same method, so that the next packaging can 9 also enters the arc-shaped groove 221 on the downstream side, to form a cycle, and each packaging can 9 is driven by the disc 22 to slide along the inner wall of the circular box 21.

[0050] When each of the rotating packaging cans 9 gradually approaches the filling assembly 3, when the first packaging can 9 rotates to the position directly below the lifting column 33 in the filling assembly 3, the disc 22 is just stopped from rotating, and then the extension end of the first lifting cylinder 32 is driven to extend outward to drive the filler to move downward, so that the first sink cavity 331 at the lower end of the lifting column 33 is sleeved outside the opening of the packaging can 9, thereby the bottom of the pressing plate 35 is pressed against the top opening of the packaging can 9, and the lifting tube 34 is elastically retracted inward by the first spring 38 as the lifting column 33 continues to move downward to achieve elastic pressing, at this time, the end of the discharge tube 36 extends into the inside center of the packaging can 9, and then the granular discharge valve 37 can be opened to make the benzotriazole particles in the storage barrel enter the discharge tube 36 through the granular discharge valve 37, the hose 310 and the lifting tube 34 in sequence, and then enter the inside of the packaging can 9 through the multiple discharge slot holes 361 on the discharge tube 36 to complete the filling, and then the same method is used to first stop and then start the speed reducer motor 23 to drive the packaging can 9 on which the filling is completed to gradually approach the can cover pre-assembly assembly 4.

[0051] When the first packaging can 9 on which the filling is completed rotates to the position below the adsorption unit, the disc 22 is just stopped from rotating, and then the moving end of the first electric sliding table 42 is driven to move upward to drive the gear 411, the second lifting cylinder 45 and the adsorption module in the adsorption unit to move upward, thereby the rotating shaft 44 is driven to rotate 180 degrees by the rack 410, so that the sleeve pipe 47 is driven to rotate to the vertical position by the seat block 46, at this time, the vacuum suction disc 49 is arranged upward and located directly below the bottom opening of the cover dropper 43, and then the extension end of the second lifting cylinder 45 is driven to extend outward to drive the vacuum suction disc 49 to move upward and extend into the inside of the bottom opening of the cover dropper 43, and the vacuum pumping device is started to work to make the vacuum suction disc 49 generate suction force, thereby the lowermost one of the can covers 10 is sucked, and then the extension end of the second lifting cylinder 45 is driven to retract inward to drive the can cover 10 to move downward until it is separated from the bottom opening of the cover dropper 43, and then the moving end of the first electric sliding table 42 is driven to move downward to reverse the gear 411, the second lifting cylinder 45 and the adsorption module by 180 degrees, thereby the sleeve pipe 47 is still rotated to the vertical position, but at this time, the vacuum suction disc 49 is arranged downward and drives the can cover 10 to move to the position directly above the opening of the first packaging can 9 on which the filling is completed, and then the extension end of the second lifting cylinder 45 is driven to extend outward to drive the can cover 10 to move downward until the opening of the can cover 10 is sleeved outside the opening of the packaging can 9, and then the vacuum pumping device is stopped to release the vacuum suction disc 49, thereby the can cover 10 is released, and then the extension end of the second lifting cylinder 45 is driven to retract inward to drive the vacuum suction disc 49 to move upward to reset, and then the same method is used to first stop and then start the speed reducer motor 23 to drive the packaging can 9 on which the can cover 10 is pre-assembled to gradually approach the can cover pre-assembly assembly 5.

[0052] When the first completed package 9 with the pre-assembly of the can lid 10 is rotated to the below of the flexible pressing block 55 in the can lid pressing assembly 5, the disc 22 is just stopped rotating, then the moving end of the second electric sliding table 52 is driven to move downward to drive the flexible pressing block 55 to move downward by the lifting seat 53 and the telescopic column 54, and then the flexible pressing block 55 is attached to the top of the can lid 10, so that the telescopic column 54 is elastically moved upward in the process of the continuous downward movement of the flexible pressing block 55, and then the flexible pressing block 55 elastically presses the can lid 10 downward, so that the can lid 10 is completely pressed and fixed at the top opening of the package 9, and then the moving end of the second electric sliding table 52 is driven to move upward to drive the flexible pressing block 55 to move upward and reset, and then the same method is used to stop and start the reduction motor 23 to drive the completed package 9 with the pre-assembly of the can lid 10 to gradually approach the can discharging assembly 8.

[0053] The second conveying line 81 is started to operate, when the first completed package 9 with the pre-assembly of the can lid 10 is rotated to the below of the flexible pressing block 55 in the can lid pressing assembly 5, the disc 22 is just stopped rotating, at this time, the completed package 9 with the pre-assembly of the can lid 10 is brought to the above of one end of the conveying belt of the second conveying line 81, then the conveying belt of the second conveying line 81 drives the above-mentioned package 9 to leave the arc-shaped groove 221 and pass through the second gap 212 to enter between the two second blocking strips 82, and finally is automatically taken out by the conveying belt of the second conveying line 81 to realize automatic discharging.

[0054] It is worth mentioning that: after the disc 22 is stopped rotating each time, the telescopic end of the positioning cylinder 61 in the positioning assembly 6 is first driven to extend outward to drive the positioning block 62 to move towards the direction of the disc 22, and then the positioning block 62 is inserted into the nearest arc-shaped groove 221 until the arc-shaped positioning surface 621 is attached to the inner wall of the arc-shaped groove 221, so that the disc 22 is prevented from loosening to play a positioning role, and before the disc 22 is rotated again, the telescopic end of the positioning cylinder 61 is driven to retract inward to drive the positioning block 62 to leave the nearest arc-shaped groove 221 so that the disc 22 can rotate normally.

[0055] The structure and principle of the lid dropping device 43 are the same as those of the cup dropping device for automatically dropping disposable paper cups, and when the lowermost can lid 10 is taken away, the remaining each can lid 10 is automatically moved downward by the thickness of the can lid 10 to wait for the next suction of the vacuum suction cup 49, which belongs to the prior art.

[0056] The utility model discloses with the help of rotation subassembly 2 realized the automatic rotation of packing jar 9 and changed position, and with the help of filling assembly 3, jar cover preloading assembly 4 and jar cover compression assembly 5 who cooperates with rotation subassembly 2 respectively realized the automatic filling of benzotriazole, automatic cover and automatic cover process, also with the help of send jar subassembly 7 and jar subassembly 8 realized the automatic sending of packing jar 9 and automatic output, and then dispensed with the necessary manual operation in turn, thereby greatly simplified the operation step to improve the filling efficiency significantly, and effectively improve the degree of automation to realize the continuous filling and reach the effect of time and effort, in addition, also significantly reduce the labor cost.
