Description

Technical Field

[0001] The present application relates to the field of packaging machinery, and in particular to an automatic packaging device for small coils. Background Art

[0002] Existing semi-automatic small coil automatic packaging equipment has the following defects: In the past, during the small coil packaging process, bubble film needed to be manually introduced. Since the swivel is wound in a rotating manner and is exposed to the outside, this operation has the potential for production accidents. When manually wrapping the tape, there are the same safety hazards as manually introducing bubble film, resulting in a low safety factor for the packaging machine. Manually affixed LOGO packaging tape needs to be manually applied while the small coil rotates. Manual packaging efficiency is slow and there are also safety hazards. In summary, the previous small coil packaging machine still required manual operation and could not guarantee manual safety. Due to its reliance on manual labor, it had poor stability, poor packaging efficiency and quality, and could not achieve continuous and efficient production. Summary of the Invention

[0081] Reference Figure 1 、 Figure 11 and Figure 12 The weighing mechanism includes a weighing and lifting assembly 91, a weighing platform 92, and a load cell. The weighing mechanism is located below the end of the conveying mechanism 1. The weighing and lifting assembly 91 is a lifting cylinder, and the weighing platform 92 is a plurality of horizontally spaced crossbars. The lifting cylinder drives the weighing platform 92 to rise and fall between the rollers of the roller conveyor. During the rise, the load cell detects the mass of the workpiece on the weighing platform 92. The weighing mechanism and the roller conveyor work together. When the workpiece is conveyed above the weighing platform 92, the lifting assembly 22 raises the weighing platform 92, thereby lifting the workpiece for weighing.

[0082] Reference Figures 1 to 12Instructions for use: When placing the film roll for the first time or performing wrapping for the first time, the end of the film needs to be passed through the film guide roller 56 and through the bottom of the film clamping cylinder 552 in the film clamping seat 551, so that the film clamping cylinder 552 clamps the film. Place the workpiece (small coil) to be wrapped and packaged manually or with the help of auxiliary tools at the head end (feed end) of the roller conveyor, and convey the workpiece to the bottom of the positioning mechanism (wrapping and packaging station) through the roller conveyor. The lifting rollers 315 in the four lifting assemblies 31 are lifted at the same time, lifting the workpiece and rotating it to drive the workpiece to rotate. At the same time, under the action of the tightening assembly 21 and the lifting assembly 22, the three tightening rollers 213 tighten the workpiece from the inner ring of the workpiece, and the three pressing rollers 214 press the workpiece from above the workpiece. The transverse moving assembly 53 and the longitudinal moving assembly 54 in the film material feeding clamp work together to drive the clamping assembly 52 (initial state is open) to move between the film material guide roller 56 and the film material pinching assembly 55. Then, the clamping assembly 52 closes and clamps the film material. The film material clamping cylinder 552 contracts and releases the film material. The transverse moving assembly 53 and the longitudinal moving assembly 54 then drive the clamping assembly 52 to pull the film material into the rotating ring 41. The rotating ring 41 rotates, and the film guide column 45 on one side of the rotating ring 41 pulls the film material, driving the film material to be wrapped around the workpiece for wrapping. After the workpiece rotates one circle, the film material clamping cylinder 552 clamps the film material, and at the same time, the film material cutting cylinder 553 cuts the film material, completing the wrapping of the workpiece. The tape moving cylinder (the tape roll is manually placed on the tape clamp 722 in advance, and the tape is tightened by the tape clamp 722, and one end of the tape is pulled out, so that the tape clamping cylinder 7242 extends and clamps, and the tape cutting cylinder 7243 is initially in a retracted state.) drives the tape clamp 722 close to the tape pillar 71, and sets the inner ring of the tape on the tape pillar 71. The tape clamp 722 contracts and loosens the tape roll to complete the loading of the tape roll, and the tape moving cylinder retracts. The rotating ring 41 rotates to carry out the tape winding and finishing operation. At the same time, the tape clamping cylinder 7242 loosens the tape for winding. After the tape is wound several times, the tape moving cylinder drives the tape clamping claw 722 and the tape clamping piece 724 close to the tape support 71. The tape clamping claw 722 holds the tape ring tightly, and the tape clamping cylinder 7242 of the tape clamping piece 724 clamps the tape. The tape cutting cylinder 7243 cuts the tape, and the tape moving cylinder retracts to complete the tape winding, that is, the film material finishing work. The packaging tape moving cylinder drives the packaging tape fixing tooling 821 close to the workpiece (the packaging tape roll is placed on the packaging tape positioning column 8212 in advance, and the packaging tape is pulled out so that the packaging tape passes over the packaging tape guide roller 8213), and the packaging tape guide roller 8213 is pressed against the side of the workpiece. The four lifting components 31 drive the workpiece to rotate, and the packaging tape is pasted as the workpiece rotates. The rotating ring 41 rotates one circle, and the packaging tape disconnecting cylinder telescopic rod extends, so that the heating wire is pressed against the packaging tape and cuts it off, completing the labeling and packaging operation.The four lifting rollers 315 of the lifting assembly 31 descend, dropping the workpiece onto the roller conveyor. The roller conveyor then transports the workpiece to the end, above the weighing mechanism. A lifting cylinder then raises the weighing platform 92 from between the rollers of the roller conveyor. A weighing sensor then measures the weight of the workpiece on the weighing platform 92. This completes the automatic packaging of the workpiece and its weight measurement.
