[0041] The separating device for the row of plastic containers of the embodiment comprises a plurality of punching units 11, which is beneficial to improve the punching efficiency, and the punching surfaces 12 of at least two punching units 11 are different in height, which avoids the problem of large punching resistance and noise caused by simultaneous punching of all punching units 11; since the punching surfaces 12 of the punching units 11 are different in height, the containers 71 fall in sequence, and the buffer mechanism can provide a buffering effect; after all the containers 71 fall to the buffer mechanism, the buffer mechanism is opened, so that the containers 71 fall onto the conveying track 6 at the same time, which avoids the problem of stacking and extrusion caused by the containers 71 falling in sequence, and the structure is simple and has good reliability.

[0042] As a preferred embodiment, the distance from the punching surfaces 12 of the plurality of punching units 11 to the upper end of the first container falling channel 31 gradually increases from one side to the other side, which can be specifically seen from Figure 3a and Figure 3c , which can realize sequential punching from one side to the other side; or, at least two punching units 11 are symmetrically arranged, which can be specifically seen from Figure 3d , which has good symmetry and stress balance, and is beneficial to improve the stability of the punching assembly 1 during operation. Specifically, please refer to Figure 3a and Figure 6 , the upper clamping part 4 is provided with an upper fixed unit 42, and the lower clamping part 3 is provided with a lower fixed unit 32; the row of plastic containers has a scrap edge, and the scrap edge area of the row of plastic containers to be cut is clamped and fixed by oppositely arranging the upper fixed unit 42 and the lower fixed unit 32, so as to divide the plastic containers into independent plastic container units to be cut. Each punching unit 11 can cut the plastic container unit from the row of plastic containers during punching, and does not affect the fixation of other plastic container units.

[0043] Specifically, please refer to Figure 2 , in the embodiment, the falling mechanism 5 is arranged below the lower clamping part 3, and the falling mechanism 5 comprises a first material blocking plate 51. The first material blocking plate 51 can play a guiding role, which facilitates the containers 71 to fall onto the conveying track 6. Specifically, please refer to Figure 5c and Figure 5d , in the embodiment, the buffer mechanism comprises a first buffer plate 53 which is reversibly turned up and down, and the first buffer plate 53 can be butted against the upper end of the first material blocking plate 51. The first buffer plate 53 is initially in a horizontal state, the containers 71 fall from the first container falling channel 31 to the first buffer plate 53, after all the containers 71 fall to the first buffer plate 53, the first buffer plate 53 is reversibly turned down to be butted against the upper end of the first material blocking plate 51, and the containers 71 are transferred to the first material blocking plate 51 under the action of gravity, and finally the first buffer plate 53 is reversibly turned up to reset, which has a simple and reasonable structure. The first buffer plate 53 is provided with an opening corresponding to the first partition plate 54, and when the first buffer plate 53 is reversibly turned down, the first partition plate 54 can pass out of the groove of the first buffer plate 53.

[0044] Referring specifically to Figure 4, in this embodiment, the first baffle plate 51 is provided with multiple first partitions 54, and a second container discharge channel 55 is formed between two adjacent first partitions 54. Multiple punching units 11 are arranged one-to-one with multiple second container discharge channels 55. The first baffle plate 51 is provided with multiple second partitions 56, and the multiple second partitions 56 are arranged one-to-one with multiple first partitions 54. The distance from the upper edge of the second partition 56 to the conveying track 6 is greater than the length of the container. When the second partition 56 is retracted towards the first baffle plate 51, a channel is formed between the conveying track 6 and the first baffle plate, allowing the container to move along the direction of the conveying track 6. The separation of the bottles punched by different punching units 11 by the first partitions 54 and the second partitions 56 helps prevent bottle tipping and jamming during the downward movement of the bottles, further improving reliability.

[0045] See details Figures 4a to 4c In this embodiment, the buffer mechanism further includes a reciprocating second buffer plate 57, which is disposed in the area of ​​the first baffle plate 51 adjacent to the conveyor track 6. Bottles falling freely may not all fall onto the conveyor track 6 simultaneously, potentially leading to bottle stacking or jamming on the high-speed conveyor track 6. The second buffer plate 57 provides a buffering effect; after all bottles have fallen onto it, the second buffer plate 57 activates, causing the bottles to fall simultaneously onto the conveyor track 6 for transport, further improving reliability. Of course, in other embodiments, the buffer mechanism may only include the second buffer plate 57 or only the first buffer plate 53.

[0046] Participate specifically Figure 4c In this embodiment, the second buffer plate 57 and the second partition plate 56 operate synchronously, thereby forming a container output channel between the first baffle plate 51 and the second baffle plate 52. Furthermore, the container output channel between the first baffle plate 51 and the second baffle plate 52 can provide vertical support to ensure that the container remains upright after leaving the punching mechanism.

[0047] See details Figure 5e and Figure 5f In this embodiment, the second buffer plate 57 is a reciprocating moving plate with its moving direction perpendicular to the conveying direction of the conveying track 6. After all the bottles have fallen onto the second buffer plate 57, the second buffer plate 57 moves away from the conveying track 6, allowing the bottles to fall onto the conveying track 6. The structure is simple and occupies little space. Of course, in other embodiments, the second buffer plate 57 can also be a flip-up structure or a telescopic structure, which will not be described in detail here.

[0048] In this embodiment, a second baffle 52 is provided on the side of the first baffle 51 away from the first container discharge channel 31. Figure 2The second material blocking plate 52 is located on the right side of the first material blocking plate 51. The second material blocking plate 52 cooperates with the first material blocking plate 51 to limit the movement of the bottle body along the width direction of the conveying track 6, which is beneficial to the falling of the bottle body on the conveying track 6.

[0049] Specifically, Figure 2 In the embodiment, the punching surface 12 of the punching assembly 1 is inclined, and the lower side of the punching surface 12 corresponds to the bottle head of the bottle body during punching. The punching surface 12 first contacts the bottle head, and then punches out the bottle head with a relatively complex structure, and then punches the bottle body and the bottle tail part, which is beneficial to guarantee the punching effect.

[0050] The punching driving member 2 includes a mounting plate 21 and a plurality of bases 22 provided on the mounting plate 21. The plurality of punching units 11 are arranged in one-to-one correspondence with the plurality of bases 22. The punching unit 11 is fixedly connected with the base 22 through a threaded fastener 23. The structure is simple, reliable, and convenient to disassemble and assemble, and is also beneficial to achieve the purpose of different heights of the punching surface 12 of the punching unit 11.

After the row of plastic containers 7 is conveyed in place, the upper clamping part 4 is lowered to clamp the row of plastic containers 7 between the upper clamping part 4 and the lower clamping part 3. Of course, in other embodiments, the upper clamping part 4 can be fixedly installed, and the lower clamping part 3 can be lifted and lowered, or both can be lifted and lowered.

[0054] S2, punching: the punching driving member 2 drives each punching unit 11 to descend synchronously, and the punching surface 12 of each punching unit 11 is punched according to different heights from the upper end of the first container material falling channel 31 in sequence, so that the containers 71 on the row of plastic containers 7 are separated from the waste material, see Figure 5c ;

[0055] S3, discharging: the punched containers 71 fall to the buffer mechanism, and after all the containers 71 fall to the buffer mechanism, the buffer mechanism is opened, so that the containers 71 fall to the conveying track 6.

[0056] Specifically, Figure 5d, the container 71 falls from the first container blanking channel 31 to the first buffer plate 53, after all the containers 71 fall to the first buffer plate 53, the first buffer plate 53 is downwardly overturned and is butted with the upper end of the first blocking plate 51, and the container 71 is transferred to the first blocking plate 51 under the action of gravity.

[0057] Or specifically participate Figure 5e And Figure 5f After all the containers 71 fall to the second buffer plate 57, the second buffer plate 57 moves away from the conveying track 6, and the container 71 can fall to the conveying track 6 for conveying.
