Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle cap processing technology, specifically a sorting device for processing PE plastic bottle caps. Background Technology
[0002] In the processing of plastic bottle caps, sorting plays a crucial role and has multiple important functions. Sorting allows for the removal of caps that do not meet size requirements, are deformed, or have cracks. These defects can prevent the cap from fitting properly to the bottle, thus affecting the packaging's seal. Only through sorting can we ensure that all bottle caps entering the market are effectively sealed, preventing leakage and spoilage of the contents, ensuring product quality and safety. Timely removal of substandard caps prevents their continued use in subsequent processing, thereby reducing raw material waste and lowering production costs.
[0003] In actual sorting of bottle caps, a feeding device is also required. However, adding a separate feeding device to the sorting equipment would increase production costs, while manual feeding would result in very low sorting efficiency. Utility Model Content

[0023] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a sorting device for processing PE plastic bottle caps, including a housing 1 and a rotating assembly. The rotating assembly is provided outside the housing 1. The rotating assembly includes a feeding pipe 201, an mounting block 202 fixedly connected to the left side of the outer wall of the feeding pipe 201, a connecting rod 203 fixedly connected to the bottom of the mounting block 202, a baffle 204 fixedly connected to the bottom of the outer wall of the connecting rod 203, a spring 205 provided on the left side of the outer wall of the baffle 204, a track plate 206 provided on the side of the spring 205 away from the baffle 204, and a mounting ball 207 fixedly connected to the left side of the outer wall of the track plate 206. A rotating disk 208 is provided on the left side of the outer wall. A first rotating shaft 209 is provided on the right side of the middle of the outer wall of the rotating disk 208. A first motor 210 is provided on the right side of the first rotating shaft 209. A feed inlet 3 is provided at the top of the outer wall of the feeding pipe 201, and a discharge outlet 4 is provided at the bottom of the outer wall of the feeding pipe 201. By setting up the rotating component, when the staff needs to feed the sorting device, they can drive the first motor 210, so that the device can drive the rotating disk 208 to rotate while performing sorting operations, and drive the track plate 206 to move back and forth, thereby completing the feeding, reducing the layout cost of the device and improving the sorting efficiency.
[0024] Please see Figure 1 , Figure 2 and Figure 3A through hole 5 is provided on the left side of the outer wall of the feeding pipe 201. A fixing block 6 is provided on the outer wall of the rotating disk 208 corresponding to the mounting ball 207. A first fixing rod 7 is provided at the connection between the outer wall of the rotating disk 208 and the first rotating shaft 209. A first output shaft 8 is provided at the connection between the first rotating shaft 209 and the first motor 210. A spiral blade 9 is fixedly connected to the outer wall of the first rotating shaft 209. A second rotating shaft 10 is provided on the front side of the outer wall of the spiral blade 9. A second fixing rod 11 is fixedly connected to the left side of the outer wall of the second rotating shaft 10. A second fixing rod 11 is fixedly connected to the right side of the outer wall of the second rotating shaft 10. A second output shaft 12 is fixedly connected, and a second motor 13 is provided on the right side of the outer wall of the second output shaft 12. A first vertical plate 14 is sleeved on the outer wall of the first output shaft 8, and a second vertical plate 15 is sleeved on the outer wall of the second output shaft 12. A storage box 16 is provided at the bottom of the outer wall of the second rotating shaft 10. By setting the first rotating shaft 209, the spiral blade 9, and the second rotating shaft 10, the staff can drive the first motor 210 and drive the second motor 13 in the opposite direction to move the bottle caps, so that they can be sorted according to the outer diameter of the bottle caps, which is convenient for the staff to operate.
[0025] Working principle: When the staff needs to sort bottle caps, the staff drives the first motor 210 to operate. At this time, the first output shaft 8 drives the first rotating shaft 209 to rotate. The first rotating shaft 209 drives the first fixed rod 7 to rotate. At the same time, the rotating disk 208 starts to rotate. When the fixed block 6 passes the surface of the mounting ball 207, the track plate 206 moves under force and applies pressure to the spring 205. At this time, the track plate 206 pushes the bottle cap out through the through hole 5 and discharges it from the discharge port 4. At the same time, the first rotating shaft 209 drives the spiral blade 9 to rotate. The staff simultaneously drives the second motor 13 in the opposite direction, driving the second rotating shaft 10 to rotate counterclockwise, so that the bottle cap moves along the spiral blade 9 and falls into the storage box 16 according to the different outer diameter sizes, completing the sorting operation. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
