Description

Technical Field

[0001] This utility model relates to a high-speed ring-top lid sorting machine, belonging to the field of high-speed ring-top lid sorting technology. Background Technology

[0002] Pull-tab caps are increasingly used in beer, beverage, and juice bottle caps. These caps consist of a round cap body and a pull ring positioned perpendicular to the edge of the cap. The biggest advantage of pull-tab caps is their ease of opening without a bottle opener. Imagine being enjoying a drink and finding no bottle opener nearby, resorting to frantic attempts with a lighter, belt, chopsticks, or even your teeth, hoping for a stroke of genius. The pull-tab cap design cleverly incorporates a pre-set indentation at the opening point, reducing localized stress. When opened, the stress near the pull ring concentrates, and under shear force, the indentation cracks, allowing the cap to open easily.

[0003] In the current packaging production line pull-tab cap sorting field, low-speed parallel discs or vibratory discs are commonly used for sorting caps. These machines generally suffer from low sorting efficiency, with traditional vibratory disc pull-tab cap sorting machines having an efficiency of 8,000-12,000 caps / hour. They also have problems such as high operating noise and a high failure rate of cap jamming.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a high-speed cap sorting machine for pull-ring caps. It can automatically sort caps under the centrifugal force of a centrifugal disc, resulting in high sorting efficiency, low cap jamming failure rate, and low operating noise.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A high-speed pull-ring cap sorting machine includes a rotating centrifugal disc, a cylindrical sidewall plate on the upper side of the centrifugal disc, a cylindrical hopper formed on the upper side of the sidewall plate, and a ring-shaped horizontal plate extending outward from the bottom of the sidewall plate. The outer edge of the centrifugal disc extends to the lower side of the horizontal plate, and an annular material feeding gap is formed between the lower surface of the horizontal plate and the upper surface of the centrifugal disc. A bottle cap outlet is provided at the lower end of the side wall panel, and an external blowing pipe is provided at the bottle cap outlet.

[0007] Furthermore, the external blowing tube is positioned on one side of the bottle cap outlet so as not to obstruct the pull ring cap from being discharged, and the blowing port at the lower end of the external blowing tube faces outward from the bottle cap outlet.

[0008] Furthermore, a drive shaft is fixedly provided at the lower end of the centrifugal disc, and the drive shaft is connected to a drive motor.

[0009] Furthermore, the lower end of the centrifuge disc is provided with a circular base plate, the drive motor is fixed on the lower surface of the base plate, and the drive shaft passes through the base plate and is connected to the centrifuge disc.

[0010] Furthermore, the outer edge of the horizontal plate extends vertically downward to form an annular extension cylinder, so that the lower end of the extension cylinder is fixed to the base plate.

[0011] Furthermore, multiple internal blowing pipes are vertically arranged on the outer side of the side wall panel, with the lower end of the internal blowing pipes extending into the side wall panel, and the multiple internal blowing pipes are arranged on the side of the material inlet relative to the bottle cap outlet.

[0012] Furthermore, a detection sensor is horizontally installed at the upper position inside the side wall panel. The detection sensor is fixed on a mounting bracket, and a baffle is suspended on the mounting bracket. The baffle is rotatably installed on the mounting bracket, and the upper end of the baffle is located in front of the detection sensor.

[0013] Furthermore, a cap delivery chute is provided on the outer side of the cap outlet.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The upper side of the centrifugal disc is provided with a cylindrical side wall plate, the upper side of which forms a cylindrical hopper. The bottom of the side wall plate extends horizontally outward to form an annular horizontal plate. The outer edge of the centrifugal disc extends to the lower side of the horizontal plate. An annular material flow gap is formed between the lower surface of the horizontal plate and the upper surface of the centrifugal disc. Only pull-ring covers with horizontal cover parts can enter the material flow gap. Under the action of centrifugal force of the centrifugal disc, automatic cover sorting is achieved.

[0018] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0019] like Figure 1-4 As shown, this utility model provides a high-speed pull-ring cap sorting machine, including a centrifugal disc 1 that is rotatably arranged, a cylindrical side wall plate 5 on the upper side of the centrifugal disc 1, a cylindrical hopper formed on the upper side of the side wall plate 5, and a ring-shaped horizontal plate 6 that extends horizontally outward from the bottom of the side wall plate 5. The outer edge of the centrifugal disc 1 extends to the lower side of the horizontal plate 6, and an annular material flow gap is formed between the lower surface of the horizontal plate 6 and the upper surface of the centrifugal disc 1. Under the action of centrifugal force, the pull ring cover 7 on the centrifugal disc 1 moves outward, and the cover part of the pull ring cover 7 is thrown into the material flow gap and rotates with the centrifugal disc 1.

[0020] A bottle cap outlet 10 is provided at the lower end of the side wall panel 5, and an external blow pipe 9 is provided at the bottle cap outlet 10.

[0021] like Figure 2 As shown, the external blowing pipe 9 is located on one side of the bottle cap outlet 10 so as not to block the pull ring cap 7 from being discharged, and the air outlet at the lower end of the external blowing pipe 9 faces the outside of the bottle cap outlet 10. When the pull ring cap 7 moves to the bottle cap outlet 10, the external blowing pipe 9 blows the pull ring cap 7 out, realizing automatic discharge.

[0022] Furthermore, a drive shaft 3 is fixedly provided at the lower end of the centrifugal disc 1, and the drive shaft 3 is connected to the drive motor 4.

[0023] The lower end of the centrifuge disc 1 is provided with a circular base plate 2. The drive motor 4 is fixed on the lower surface of the base plate 2, and the drive shaft 3 passes through the base plate 2 and is connected to the centrifuge disc 1.

[0024] The outer edge of the horizontal plate 6 extends vertically downward to form an annular extension cylinder, and the lower end of the extension cylinder is fixed to the base plate 2. This fixes the lower ends of the side wall plate 5 and the horizontal plate 6 to the base plate 2.

[0025] like Figure 2 and Figure 3 As shown, a plurality of internal blowing pipes 8 are vertically arranged on the outer side of the side wall panel 5. The lower end of the internal blowing pipe 8 extends into the side wall panel 5, and the plurality of internal blowing pipes 8 are arranged on the side opposite to the material inlet of the bottle cap outlet 10.

[0026] The pull-ring cap 7 is on the centrifugal disc 1. Under the action of centrifugal force, the cap body of the pull-ring cap 7 is inserted into the material flow gap. Driven by the rotation of the centrifugal disc 1, it moves closer to the bottle cap outlet 10 along the material flow gap. When it approaches the bottle cap outlet 10, the outer blow pipe 9 blows away the pull-ring cap 7 that is close to the material flow gap, preventing multiple pull-ring caps 7 from piling up together and hindering the movement of the pull-ring cap 7 in the material flow gap. At the same time, under the blowing force of the inner blow pipe 8, the cap body of the pull-ring cap 7 is made to be in a horizontal position so that the cap body can be inserted into the material flow gap.

[0027] Only pull ring covers 7 with horizontal cover sections can enter the material feeding gap. Under the centrifugal force of centrifugal disc 1, automatic cover sorting is achieved, resulting in high cover sorting efficiency, low failure rate of cover jamming, and low operating noise.

[0028] A detection sensor 11 is horizontally installed at the upper part of the side wall panel 5. The detection sensor 11 is fixed on the mounting bracket 13, and a baffle 12 is suspended on the mounting bracket 13. The baffle 12 is rotatably mounted on the mounting bracket 13, and the upper end of the baffle 12 is located in front of the detection sensor 11. When there are many pull ring covers 7 in the centrifugal disc 1, the deflection angle of the baffle 12 is large, making it impossible for the detection sensor 11 to detect the baffle 12. At this time, the feeding device can be controlled to stop adding pull ring covers 7 into the side wall panel 5.

[0029] The bottle cap outlet 10 is also provided with a cap conveying slide 14 on the outside, so that the pull ring cap 7 can slide through the cap conveying slide 14 to the capping device and install the pull ring cap 7 onto the bottle mouth.
