[0028] See also Figure 1-3, an automatic trimming device for tinplate can tops, comprising a support platform 1, a turntable 2 is installed on the upper end of the support platform 1, a plurality of evenly distributed limiting grooves 3 are opened at the edge end of the turntable 2, a sealing strip 4 is fixedly connected to the edge end of the upper side of the support platform 1, and a feed port 5, a limiting port 6, and a discharge port 7 are opened in sequence at the upper end of the sealing strip 4 in a counterclockwise rotation, a placement base 8 is installed on the outer side of the limiting port 6, and a side end of the placement base 8 is pneumatically connected to a retractable telescopic bracket 81, and a trimming piece 9 is fixedly connected to the side end of the placement base 8.

[0029] More specifically: a telescopic bracket three 71 is installed at the upper end of the support platform 1, the telescopic end of the telescopic bracket three 71 is located between the inner walls of the discharge port 7, a conveyor belt two 72 is installed on the outside of the discharge port 7, a conveyor belt one 51 is installed on the outside of the feed port 5, a telescopic bracket two 52 is provided on one side of the conveyor belt one 51, and the telescopic end of the telescopic bracket two 52 is located between the inner walls of the feed port 5.

[0030] During use of this solution, in order to enable the existing tinplate can top covers to achieve large-scale automated trimming operations, in this embodiment, a conveyor belt 1 51, a placement base 8, and a conveyor belt 2 72 are installed in sequence on one side of the support platform 1 in a counterclockwise rotation, so that subsequent personnel can transport batches of tinplate can top covers from above the conveyor belt 1 51. When each tinplate can top cover is transported to the side of the feed port 5, the telescopic end of the telescopic bracket 2 52 pushes it, causing the tinplate can top cover to be pushed into the limiting groove 3 on the side of the turntable 2, and then with the continuous rotation of the turntable 2 and under the limitation of the sealing bar 4, the batches of tinplate can top covers fall into the limiting groove 3 one by one. Inside, then, when the single tinplate can top cover rotates to one side of the limit port 6, it stops rotating. At this time, the telescopic end of the telescopic bracket 1 81 pushes the tinplate can top cover to hit the inner wall of the limit slot 3 for limitation. After that, the trimming operation of the tinplate can top cover is completed by driving the trimming piece 9 downward. After that, after the tinplate can top covers are trimmed one by one and transmitted to the side of the discharge port 7, the telescopic end of the telescopic bracket 3 71 pushes the tinplate can top cover from the discharge port 7 to the top of the conveyor belt 2 72, so that the trimmed tinplate can top cover is conveyed to the other side, thereby completing the automated trimming operation of large quantities of tinplate can top covers and improving the trimming efficiency of tinplate can top covers by existing personnel.

[0031] See also Figure 1-3 The trimming member 9 includes a placement box 91 fixedly connected to the side end of the placement base 8. The interior of the placement box 91 is fixedly connected with a vertical plate 1 92, a vertical plate 2 93 and a vertical plate 3 94 from top to bottom. A receiving through hole 95 is opened at the bottom end of the vertical plate 3 94. A transmission component 1 is installed between the upper and lower inner walls of the vertical plate 1 92 and the vertical plate 2 93.

[0032] More specifically: the transmission component 1 includes a vertical plate 1 92 and a vertical plate 2 93, between which the upper and lower inner walls are rotatably connected to a transmission wheel 2 98, the upper end of the vertical plate 1 92 is installed with a motor 1, the output end of the motor 1 is fixedly connected to the transmission shaft of the transmission wheel 2 98, the bottom end of the other side of the vertical plate 1 92 is fixedly connected to a bearing shaft 96, the outer end of the bearing shaft 96 is movably connected to a transmission wheel 1 97, a transmission belt 99 is sleeved between the transmission wheel 1 97 and the transmission wheel 2 98, the lower end of the transmission wheel 1 97 is fixedly connected to two symmetrically distributed telescopic rods 910, the lower end of the telescopic rod 910 is fixedly connected to a grinding sleeve 911, and a transmission component 2 is installed between the inner walls of the transmission wheel 1 97.

[0033] More specifically, the transmission component 2 includes a threaded rod 108 provided between the inner walls of the transmission wheel 197, the upper end of the vertical plate 102 is fixedly connected to the vertical platform 101, the threaded rod 108 is rotatably connected to the inner wall of the top side of the vertical platform 101, the top of the threaded rod 108 is fixedly connected to the bevel gear 102, and a motor 2 103 is installed on one side of the vertical plate 102, the output end of the motor 2 103 is fixedly connected to the bevel gear 2 104, and the bevel gear 2 104 is meshed with the bevel gear 102 for transmission, and the lower end of the bearing shaft 96 is fixedly connected to two symmetrically distributed connecting side plates 105, and a limiting sleeve 106 is fixedly connected between the inner bottom walls of the connecting side plates 105, and a movable sleeve 107 is inserted between the inner walls of the limiting sleeve 106, and the movable sleeve 107 is sleeved on the outside of the threaded rod 108 and threadedly connected to it, and the movable sleeve 107 is rotatably connected to the polishing sleeve 911.

[0034] When the tinplate can top cover is rotated and displaced to the side of the limit opening 6, the telescopic bracket 1 81 is first extended outward, thereby causing the tinplate can top cover to contact the inner wall of the limit groove 3 and limit it, so that the grinding sleeve 911 is located just above the tinplate can top cover. Then, the personnel drives the motor 2 103 to cause the bevel gear 2 104 to drive the bevel gear 102 to engage and transmit, and under the penetration connection of the threaded rod 108, the threaded rod 108 is passively rotated synchronously. At the same time, under the threaded connection between the threaded rod 108 and the movable sleeve 107, and the movable sleeve 107 is limited by the limit sleeve 106, the threaded rod 108 is caused to convert the rotational motion of the movable sleeve 107 into linear motion after rotation, and the grinding sleeve 911 connected to the bottom side of the tinplate can is driven to move up and down, so that the grinding sleeve 911 is sleeved on the outside of the tinplate can top cover.

[0035] After the grinding sleeve 911 is located on the outside of the tinplate can top cover, the personnel can drive the motor 1, and under the linkage of the transmission belt 99, the transmission wheel 2 98 drives the transmission wheel 1 97 to perform synchronous transmission. Since the transmission wheel 1 97 is fixedly connected to the grinding sleeve 911, the grinding sleeve 911 located on the outside of the tinplate can top cover can be driven to rotate synchronously, thereby completing the trimming operation of the tinplate can top cover.

[0036] After the trimming is completed, the personnel can reverse the above operation to cause the grinding sleeve 911 to retract into the receiving through hole 95 to facilitate the subsequent tinplate can top cover transportation and trimming operations, thereby forming a streamlined automated working phenomenon and greatly improving the trimming efficiency of the tinplate can top cover.

[0037] In this embodiment, the control programs of motor 1, motor 2 103, the driving member for rotating the turntable 2, conveyor belt 1 51, telescopic bracket 2 52, telescopic bracket 1 81, telescopic bracket 3 71, and conveyor belt 2 72 are set to the same PLC program for operation.

[0038] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
