For example, the heights of the two ends of the cassette plugs are similar, and the diameter difference between the two ends is only 0.1mm. After sorting, the end with the larger diameter of the plug should be facing the bottle body and plugged into the bottle. The front and back of the cassette plugs need to be distinguished during the sorting process. The plugs are transported by hanging slide rails, the sorting efficiency is low, and there is a defect that it is difficult to distinguish the front and back of the plugs. Summary of the invention

The outlet of the feeding channel 21 is located above the entrance of the first material pouring and screening channel 22. A first through hole 221 for removing a rubber plug for horizontal conveying is provided on the side of the first material pouring and screening channel 22. The forward and reverse screening channel 23 is used to change the conveying state of a rubber plug with a larger diameter end facing downward and conveyed vertically to horizontal conveying. A second through hole 241 for removing a rubber plug for horizontal conveying is provided on the side of the second material pouring and screening channel 24, so that the rubber plug changes its conveying state multiple times and the rubber plugs in different conveying states are screened, so as to realize rubber plug sorting with high material sorting efficiency and accurate distinction between the forward and reverse sides of the rubber plug.

[0006] As a further improvement of the above technical solution:

[0007] The feeding channel is connected to the vibration bucket body 1 , and the feeding channel 21 is a curved ascending channel, so that when the rubber plug moves along the feeding channel 21 , it is basically transported horizontally.

[0008] The height of the first through hole 221 is H1, and the length is L1. The height of the second through hole 241 is H2, and the length is L2. The height of the rubber plug is h, and the maximum diameter of the rubber plug is R1. Among them, H1>R1, L1>h, H2>R1, L2>h, so that the horizontally transported rubber plug can leave the material handling channel 2 through the first through hole 221 and the second through hole 241.

[0009] The width of the feed port of the forward and reverse screening channel 23 is W, and the diameters of the two ends of the rubber plug are R1 and R2 respectively, wherein R1>R2, R1>W≥R2, so that the rubber plug with a diameter of R1 and one end facing downward and transported vertically cannot vertically enter the feed port of the forward and reverse screening channel 23, while the rubber plug with a diameter of R2 and one end facing downward and transported vertically can vertically enter the feed port of the forward and reverse screening channel 23, thereby performing forward and reverse screening on the vertically transported rubber plug.

[0010] A block 231 is provided on one side of the bottom of the forward and reverse screening channel 23, and a side baffle 232 is provided on the other side of the forward and reverse screening channel 23. A channel for vertically conveying the rubber plug is formed between the side of the block 231 and the side baffle 232. The block 231 can be adjusted and installed on the forward and reverse screening channel 23. A channel for horizontally conveying the rubber plug is formed between the upper surface of the block 231 and the side baffle 232. The rubber plug with a diameter of R1 facing downward at one end and conveyed vertically cannot vertically enter the feed port of the forward and reverse screening channel 23, and is blocked by the block 231, thereby changing the conveying state to horizontal conveying and conveying on the upper surface of the block 231.

[0011] The first through hole 221 and the second through hole 241 are connected to the vibration bucket body 1, so that the horizontally transported rubber plug returns to the vibration bucket body 1 and re-enters the material sorting channel 2 for material sorting.

An upper baffle 27 is provided above the connection between the discharge channel 26 and the flip channel 25. The number of the discharge channels 26 is greater than the number of the flip channels 25. The upper baffle 27 is used to prevent the rubber plugs from overlapping and reversing, so as to keep the end with the larger diameter facing downward and output the material handling channel 2.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4 As shown, a rubber plug conveying mechanism includes a material sorting channel 2, which includes a feeding channel 21, a first material pouring and screening channel 22, a forward and reverse screening channel 23 and a second material pouring and screening channel 24 connected in sequence, the outlet of the feeding channel 21 is located above the inlet of the first material pouring and screening channel 22, a first through hole 221 for removing the rubber plug for horizontal conveying is provided on the side of the first material pouring and screening channel 22, the forward and reverse screening channel 23 is used to change the conveying state of the rubber plug with the larger diameter end facing downward to horizontal conveying, and a second through hole 241 for removing the rubber plug for horizontal conveying is provided on the side of the second material pouring and screening channel 24, so that the rubber plug changes its conveying state multiple times, and the rubber plugs in different conveying states are screened, so as to realize rubber plug sorting with high material sorting efficiency and accurate distinction between the forward and reverse sides of the rubber plug.

[0025] The feeding channel is connected to the vibration bucket body 1. The feeding channel 21 is a curved ascending channel, so that when the rubber plug moves along the feeding channel 21, it is basically transported horizontally. Due to the different diameters at both ends of the rubber plug, in the process of being transported upward by bending through the vibration bucket body 1 to the feeding channel 21, among the rubber plugs transported flatly upward, the end of the rubber plug with a larger diameter is located at the bottom more often than the end of the rubber plug with a smaller diameter is located at the bottom. When the height difference between the feeding channel 21 and the first material pouring and screening channel 22 makes the horizontally transported rubber plugs become vertical after falling, most of the rubber plugs are at the end with a smaller diameter located at the bottom and are transported vertically. Only a small number of rubber plugs are at the end with a larger diameter located at the bottom and are transported vertically due to the very small difference in diameter between the two ends of the rubber plugs.

[0026] The height of the first through hole 221 is H1, and the length is L1. The height of the second through hole 241 is H2, and the length is L2. The height of the rubber plug is h, and the maximum diameter of the rubber plug is R1. Among them, H1>R1, L1>h, H2>R1, L2>h, so that the horizontally transported rubber plug can leave the material handling channel 2 through the first through hole 221 and the second through hole 241.

[0027] The width of the feed port of the forward and reverse screening channel 23 is W, and the diameters of the two ends of the rubber plug are R1 and R2 respectively, wherein R1>R2, R1>W≥R2, so that the rubber plug with a diameter of R1 and one end facing downward and transported vertically cannot vertically enter the feed port of the forward and reverse screening channel 23, while the rubber plug with a diameter of R2 and one end facing downward and transported vertically can vertically enter the feed port of the forward and reverse screening channel 23, thereby performing forward and reverse screening on the vertically transported rubber plug.

[0028] A stopper 231 is provided on one side of the bottom of the forward and reverse screening channel 23, and a side baffle 232 is provided on the other side of the forward and reverse screening channel 23. A channel for vertically conveying the rubber plug is formed between the side of the stopper 231 and the side baffle 232. The stopper 231 can be adjusted and installed on the forward and reverse screening channel 23. A waist-shaped hole is provided on the stopper 231. The stopper 231 is installed on the forward and reverse screening channel 23 by passing a locking piece through the waist-shaped hole. The position of the stopper 231 can be adjusted to make the setting of the feed port width W more accurate. A channel for horizontally conveying the rubber plug is formed between the upper surface of the stopper 231 and the side baffle 232. The rubber plug with a diameter of R1 facing downward at one end and conveyed vertically cannot vertically enter the feed port of the forward and reverse screening channel 23, and is blocked by the stopper 231, thereby changing the conveying state to horizontal conveying and conveying on the upper surface of the stopper 231.

[0029] The first through hole 221 and the second through hole 241 are connected to the vibration bucket body 1, so that the horizontally transported rubber plug returns to the vibration bucket body 1 and re-enters the material sorting channel 2 for material sorting.

[0030] The material handling channel 2 also includes a flip channel 25. The second material discharging and screening channel 24 is connected to the flip channel 25. Spirally arranged side plates 251 are provided on both sides of the flip channel 25. The rubber plug is flipped 180 degrees through the flip channel 25 so that the end of the rubber plug with a larger diameter faces downward for transportation.

[0031] The material handling channel 2 also includes a discharge channel 25. The flip channel 25 is connected to the discharge channel 26. An upper baffle 27 is provided above the connection between the discharge channel 26 and the flip channel 25. The number of the discharge channels 26 is greater than the number of the flip channels 25. For example, three flip channels 25 are provided and 8 discharge channels 26 are provided. The upper baffle 27 prevents the rubber plug coming out of the flip channel 25 from overlapping and reversing when entering the discharge channel 26, so that the rubber plug maintains a posture with the end with a larger diameter facing downward, and is output from the material handling channel 2.

[0032] A plurality of material sorting channels 2 are arranged in parallel, and the plurality of material sorting channels 2 can sort materials synchronously. The material sorting channels are all arranged in parallel on the vibration bucket body 1, and the structure layout is reasonable, thereby improving the material sorting efficiency.

[0033] A rubber plug conveying method, comprising a rubber plug conveying mechanism, wherein the rubber plug enters a material sorting channel 2, and falls from a high place to a first material discharging and screening channel 22 through a material feeding channel 21. The rubber plug falls into the first material discharging and screening channel 22, and the rubber plug is conveyed horizontally or vertically with the end with a larger diameter facing downward or vertically with the end with a smaller diameter facing downward. The horizontally conveyed rubber plug leaves the material sorting channel 2 through a first through hole 221; the remaining rubber plugs enter a forward and reverse screening channel 23, and the rubber plugs conveyed vertically with the end with a larger diameter facing downward are blocked in the forward and reverse screening channel 23 and are changed to be conveyed horizontally to enter the first The rubber plugs transported vertically with the smaller end facing downwards in the second material discharging and screening channel 24 maintain the transport state and enter the second material discharging and screening channel 24. The rubber plugs transported horizontally in the second material discharging and screening channel 24 leave the material sorting channel 2 through the second through hole 241. The rubber plugs transported vertically with the smaller end facing downwards maintain the transport state and enter the flipping channel 25. The flipping channel 25 flips the rubber plugs so that the end with the larger diameter faces the output direction for horizontal transport. The horizontally transported rubber plugs enter the discharge channel 26, completing the material sorting and output, realizing the distinction between the positive and negative sides of the rubber plugs, and the material sorting efficiency is high.
