[0036] The feeding mechanism a1 includes a workbench 11, and also includes a blanking member 12, a pushing member 13, and a picking member a14 mounted on the workbench 11. The blanking member 12 is located between the pushing member 13 and the picking member a14. Several lids are stacked longitudinally within the blanking member 12, and one end of the pushing member 13 extends directly below the blanking member 12. The movement of the pushing member 13 pushes the bottom lid to move below the picking member a14. The picking member a14 first moves downward to pick up the lid, then resets and moves forward to place the lid above the cap-locking mechanism 3. After completing the feeding process of the feeding mechanism a1, it resets.
[0037] The workbench 11 is provided with transverse mounting posts 4 on both sides, which are threadedly connected to the workbench 11. The blanking component 12 includes two fixing rods 15 fixed to the mounting posts 4 by threads and at least four fixing blocks 121 threadedly mounted above the fixing rods 15. It also includes four blanking rods 122 fixed to one side of the fixing blocks 121. Several longitudinally stacked lids are clamped between the four blanking rods 122, which serve as a limit for the lids. The bottom of the blanking rods 122 is connected to the fixing blocks 121 to be suspended above the workbench 11, and a discharge channel 123 for the lids to pass through is formed between the blanking rods 122 and the workbench 11. The lids are displaced and discharged through the discharge channel 123. When the last lid is discharged, several stacked lids fall by their own gravity, and this cycle continues. Four connecting rods 124 are provided at the upper end of the blanking component 12. The connecting rods 124 are arranged around the periphery of the four blanking rods 122. The connecting rods 124 are threadedly connected to the blanking rods 122 to increase the stability of the blanking rods 122 and prevent the blanking rods 122 from shaking or even dislocation due to external forces.
[0038] The pushing member 13 includes two fixing rods 15 with both ends threadedly connected to the mounting column 4, a pushing cylinder 131 installed on the upper end of the fixing rod 15, and a pushing plate 132 that is movable on the workbench 11.

There are four lid-locking members 33, distributed in the front, back, left, and right directions, corresponding to the four fasteners on the lid. After the lid and box are both fed, the four lid-locking members 33 push the fasteners on the lid to snap onto the box, completing the assembly of the lid and box. The lid-locking members 33 are tilted at 15-40 degrees, adapting to the angle of the fasteners and further facilitating the fastening. The bottom and top of the base plate 31 are provided with connecting columns for connecting and fixing the four columns 33, increasing the stability of the columns 33. The storage block 34 is mounted to the connecting columns at the top with screws.
[0043] The cover assembly 33 comprises a cover cylinder 331, blocks 332 attached to either side of the cover cylinder 331, and a connecting block for connecting the cover cylinder 331 and the blocks 332, which are screwed together. A connecting piece 333 extends from one side of the blocks 332, and the cover assembly 33 is screwed to the column 33 via the connecting piece 333. The expansion and contraction of the cover cylinder 331 drives the fasteners on the outside of the cover to snap onto the box.
