[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Figures 1 to 9 An embodiment of the plastic bottle punching device of the present invention is shown. The plastic bottle punching device of this embodiment includes a first blade plate 1 and a second blade plate 2 arranged opposite each other. The first blade plate 1 is provided with a punching member 3 for punching out a single bottle body 91. The second blade plate 2 is connected to a blanking mechanism. The blanking mechanism includes a bottle support plate 61, a movable driving member 62 for driving the bottle support plate 61 to move back and forth, and multiple single bottle channels located above the bottle support plate 61. A bottle conveying mechanism (not shown) is provided below the bottle support plate 61. The movable driving member 62 can be, for example, a cylinder, an electric push rod, or a screw nut pair; the bottle conveying mechanism can be, for example, a bottle conveying track or a bottle conveying mesh belt.

[0033] In the plastic bottle punching device of this embodiment, the punching part 3 directly punches out a single bottle body 91, and each single bottle body 91 respectively falls onto the bottle supporting plate 61 through the single bottle channel corresponding to the dropping mechanism (the waste generated by the punching of the plate 9 is dropped through the waste hopper 45). At this time, the bottle body is converted from a horizontal state to a vertical state, and then the moving driving part 62 drives the bottle supporting plate 61 to move, so that the bottle body 91 falls onto the bottle conveying mechanism (see the embodiment for details). Figure 3 , the bottle 91 falls from the upper left to the lower right, and the bottle support plate 61 moves to the left, causing the bottle 91 to fall vertically to the bottle conveying mechanism below). This helps prevent the single bottle 91 from falling over due to its light weight. The structure is simple and reliable, and no further cutting is required. When it is necessary to use the plastic bottle punching device of this embodiment to produce row bottles 91, there is no need to disassemble the entire set of molds. Only the punching part 3 and the blanking mechanism without the single bottle channel need to be replaced (see Figures 4 to 6 , specifically the turning plate 44, the blanking plate 51 and the bottle supporting plate 61), which is easy to operate, helps to save replacement time, and only requires one person to complete the replacement.

[0034] In this embodiment, the blanking mechanism includes a first blanking assembly 4, which includes a tilting seat 41, a tilting drive 42 (e.g., a pneumatic cylinder, an oil cylinder, an electric push rod, etc.) for driving the tilting seat 41 to tilt up and down, and a plurality of first single-bottle channels 43 provided on the tilting seat 41. Initially, the tilting seat 41 is in a horizontal position to receive the punched bottles 91. After all bottles 91 have fallen into their corresponding first single-bottle channels 43, the tilting drive 42 drives the tilting seat 41 to tilt downward to a tilted position, allowing the bottles 91 in the first single-bottle channels 43 to slide downward, thereby preventing material jams.

[0035] Furthermore, in this embodiment, a turning plate 44 is provided on the turning seat 41, and a groove is provided on the turning plate 44 to form a first single bottle channel 43. Figures 4 to 6 A groove is formed on the flip plate 44 to form the first single-bottle channel 43. This integrally formed structure is more conducive to ensuring structural strength compared to the installation of partitions. Preferably, both ends of the flip plate 44 are fixed to the flip seat 41 using threaded fasteners such as bolts and screws, which facilitates replacement when producing the row of bottles 91.

[0036] See Figure 5 Furthermore, in this embodiment, the blanking mechanism also includes a second blanking assembly 5 that interfaces with the first blanking assembly 4. The second blanking assembly 5 includes a blanking plate 51 and multiple first baffles 52 arranged parallel to the blanking plate 51 (preferably, the first baffles 52 are welded to the blanking plate 51). Second single-bottle channels 53 are formed between adjacent first baffles 52. The multiple second single-bottle channels 53 are arranged in a one-to-one correspondence with the multiple first single-bottle channels 43. After sliding down in a first single-bottle channel 43, the bottle body 91 enters the corresponding second single-bottle channel 53 and then continues to slide down the second single-bottle channel 53, which helps prevent the bottle from getting stuck.

[0037] See Figure 5 and Figure 6 Furthermore, in this embodiment, multiple second partitions 63 are arranged in parallel on the bottle support plate 61 (preferably, the second partitions 63 are welded to the bottle support plate 61). A third single-bottle channel 64 is formed between two adjacent second partitions 63. The multiple third single-bottle channels 64 are arranged in a one-to-one correspondence with the multiple second single-bottle channels 53. After sliding down from the second single-bottle channel 53, the bottle 91 enters the corresponding third single-bottle channel 64 and falls along the third single-bottle channel 64 onto the bottle support plate 61. At this time, the bottle 91 is in a vertical position. After the bottle support plate 61 moves to the left, the bottle 91 falls onto the bottle conveying mechanism below.

[0038] Furthermore, in this embodiment, the first baffle 52 is disposed on the upper side of the blanking plate 51, and a baffle passage 511 is provided on the lower side of the blanking plate 51 for the second baffle 63 to pass through. As the second baffle 63 reciprocates with the bottle support plate 61, it can pass through the baffle passage 511, thereby better connecting the first baffle 52 and the second baffle 63, reducing the gap and ensuring efficient bottle blanking.

[0039] As a preferred embodiment, an upwardly bent portion 611 is provided on one side of the bottle supporting plate 61, and the movable driving member 62 and the second partition plate 63 are both connected to the bent portion 611. The provision of the bent portion 611 can, on the one hand, improve the strength of the bottle supporting plate 61 itself and reduce deformation; on the other hand, it can improve the connection strength between the bottle supporting plate 61 and the second partition plate 63, while also facilitating the connection between the bottle supporting plate 61 and the movable driving member 62, resulting in a simple and effective structure.

[0040] See Figure 1 、 Figure 7 and Figure 8 As a preferred embodiment, the first cutting edge plate 1 is located above the second cutting edge plate 2, and accordingly, the punching piece 3 performs punching from top to bottom, and a sheet material conveying mechanism 7 is provided on the side of the second cutting edge plate 2 (specifically on the left side).

[0041] See Figure 2 and Figure 7 Furthermore, in this embodiment, the sheet material conveying mechanism 7 includes a guide plate 71, and the guide plate 71 is provided with an overlapping portion 711. The overlapping portion 711 is provided on the second cutting edge plate 2 and extends to the side of the second cutting edge plate 2 away from the guide plate 71 (that is, the overlapping portion 711 extends to the right side of the second cutting edge plate 2 and completely penetrates the second cutting edge plate 2), which is beneficial to strengthening the guiding effect of the guide plate 71 on the sheet material 9, and is also beneficial to increasing the overlapping length of the overlapping portion 711 and the second cutting edge plate 2, thereby improving the structural strength. At the same time, the corresponding portion of the second cutting edge plate 2 and the overlapping portion 711 is a plane, which can be milled out at one time, which is beneficial to reducing the processing difficulty of the second cutting edge plate 2 (on the contrary, if the overlapping portion 711 is only overlapped on the left side of the second cutting edge plate 2, the upper surface of the second cutting edge plate 2 is a stepped surface, and the processing difficulty will increase).

[0042] See Figure 9Furthermore, in this embodiment, the first blade plate 1 is mounted on the mounting frame 8. A lifting drive member connection portion 81 is provided at each diagonal end of the mounting frame 8 (i.e., the lifting drive member 83 is connected to the lifting drive member connection portion 81). A guide shaft mounting portion 82 is provided at each other diagonal end of the mounting frame 8 (i.e., the guide shaft 84 is mounted on the guide shaft mounting portion 82). The lifting drive member 83 drives the first blade plate 1 up and down so as to cooperate with the second blade plate 2 to compress or release the sheet material 9. The guide shaft 84 provides guidance for the lifting movement of the first blade plate 1, ensuring movement accuracy and preventing deviation. The two lifting drives 83 and the two guide shafts 84 are both installed diagonally, which helps simplify the structure, increase assembly space, and further facilitate operation for the operator.
