the plastic barrel after injection molding falls on the inclined plane sliding table 20, then the plastic barrel slides into the upper side of the processing table 11, and the plastic barrel is abutted against the auxiliary limit rod 76, thereby realizing the positioning of the plastic barrel, then the motor 84 is started, the motor 84 drives the second rotating shaft 32, the gear 33 and the belt wheel 34 to rotate, the gear 33 drives the lifting rack 31 to move downwards through meshing connection, the lifting rack 31 drives the lifting rod 30, the inclined plane block 29 and the lifting plate 49 to move downwards, under the action of the torsion spring 43, the lever 27 rotates, the lever 27 is connected with the sliding pin 45 in a sliding way through the sliding groove 40 to drive the push rod 28 and the sliding rod 23 to move, the push rod 28 moves rightwards, the push rod 28 drives the auxiliary piston 26 to move rightwards, air flow is conveyed into the auxiliary air cavity 25 through the one-way valve 41, thereby enabling the auxiliary piston 26 to move normally, the sliding rod 23 drives the wedge block 46 to move leftwards, the rack 37 drives the pinion 78 and the gear shaft 79 to rotate through meshing connection, the pinion 78 drives the pinion 80 to move upwards through meshing connection, the pinion 80 abuts against the lifting plate 14 through the double-bevel block 83 and drives the lifting plate 14 to move upwards, the lifting plate 14 drives the support table 73 and the sub-support table 77 to move upwards, after the lifting plate 14 abuts against the nut 72, the lifting plate 14 pushes the double-bevel block 83 to move rightwards, then the double-bevel block 83 and the sliding barrel 81 move to the upper side of the lifting plate 14, under the action of the third compression spring 82, the double-bevel block 83 moves leftwards and returns, then the clamping block 39 abuts against the plastic barrel, the lifting rod 30 continues to move downwards, then the clamping block 39, the fixing rod 50 and the sliding bevel block 52 move upwards relative to the lifting rod 30, the sliding bevel block 52 abuts against the slave rod 54, the sliding bevel block 52 pushes the slave driven rod 54 and the bevel limit rod 56 to move leftwards, so that the bevel limit rod 56 is separated from the limit hole 55, meanwhile, the sliding inclined plane block 52 triggers the position switch 53, the motor 84 stops rotating, and meanwhile, as the inclined plane limiting rod 56 is separated from the limiting hole 55, under the action of the fourth compression spring 87, the lifting plate 49, the auxiliary shearing knife 48 and the shearing knife 38 move downwards to be abutted against the corresponding supporting platform 73 and the auxiliary supporting platform 77, so that the plastic barrel is sheared and trimmed, and plastic waste generated by shearing and trimming falls into the crushing cavity 12 through the supporting cavity 13; meanwhile, the belt wheel 34 drives the auxiliary belt wheel 85 to rotate through the V belt 35, the auxiliary belt wheel 85 drives the first rotating shaft 16 on the left side to rotate, the first rotating shaft 16 on the left side drives the transmission gear 86 on the left side to rotate, and the transmission gear 86 on the left side drives the transmission gear 86 on the right side to rotate through meshing connection, so that the two first rotating shafts 16 and the crushing wheel 15 are driven to rotate oppositely, and crushing movement required by crushing of the plastic trimming waste is realized; then the motor 84 drives the second rotating shaft 32, the gear 33 and the belt wheel 34 to rotate reversely, the belt wheel 34 drives the secondary belt wheel 85 to rotate through the V-shaped belt 35 to carry out the crushing movement, and therefore the crushing of the plastic trimming waste is realized; meanwhile, the three-way electromagnetic valve 61 acts to enable the air channel pipe 21 to be communicated with the air cavity 19, the gear 33 drives the lifting rack 31, the lifting rod 30, the inclined plane block 29 and the clamping block 39 to move upwards through meshing connection, the clamping block 39 is separated from the plastic barrel, the clamping block 39, the fixing rod 50 and the sliding inclined plane block 52 move downwards and reset relative to the lifting rod 30 under the action of the extension spring 51, the inclined plane block 29 moves upwards to be abutted against the push rod 28, the push rod 28 pushes the push rod 28 to move leftwards, the push rod 28 drives the auxiliary piston 26 to move leftwards and reset, air flow generated by the left movement of the auxiliary piston 26 is conveyed into the air cavity 19 through the air channel pipe 21 and pushes the piston 60, the piston rod 63 and the push plate 69 to move rightwards, so that the push plate 69 can convey the trimmed plastic barrel to the outside to be stored rightwards, when the push plate 69 moves rightwards to the right limit, the piston 60 triggers the auxiliary position switch, the air channel pipe 21 is not communicated with the air cavity 19, under the action of a second compression spring 59, the piston 60 and the push plate 69 move leftwards and reset, the push rod 28 is in sliding connection with the slide groove 40 on the upper side through the slide pin 45 on the upper side to drive the lever 27 to rotate reversely, so that the lever 27 can be reset by moving the slide rod 23 rightwards, the slide rod 23 drives the wedge block 46 to move rightwards, the wedge block 46 is abutted with the driven rod 47 and pushes the driven rod 47 and the lifting plate 49 to move upwards, the speed of the lifting plate 49 moving upwards is greater than that of the lifting rod 30, so that the lifting plate 49 moves upwards and resets relative to the lifting rod 30, the lifting plate 49 pushes the inclined plane limiting rod 56 leftwards, then the limiting hole 55 moves to the inclined plane limiting rod 56, under the action of the first compression spring 58, the inclined plane limiting rod 56 moves rightwards to the limiting hole 55, so that the limiting hole 55 is locked again, meanwhile, the lifting rod 30 drives the fixing plate 36 and the rack 37 to move, after the auxiliary rack 80 drives the lifting plate 14 to move downwards through the double-inclined-surface block 83 and reset, the lifting plate 14 pushes the double-inclined-surface block 83 to move rightwards, so that the double-inclined-surface block 83 can move to the lower side of the lifting plate 14, and one-time plastic barrel trimming is completed.

The invention has the beneficial effects that: the trimming and shearing auxiliary device can automatically position the plastic barrel so as to facilitate trimming work, the plastic barrel trimming device can automatically clamp the plastic barrel and then automatically trim the plastic barrel, meanwhile, the trimming and shearing auxiliary device can adapt to trimming work of plastic barrels with different heights through manual adjustment, the pushing device can convey the trimmed plastic barrel to the outside for storage, and the trimming waste recovery device can crush waste generated by trimming so as to facilitate waste recycling and reduce storage space required by the waste.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
