[0033] like Figures 1-5 As shown, this embodiment provides a whole tray of plastic cups cutting device, including:
[0034] Mounting base 1, with a placement plate 6 on one side for holding the cut plastic cups;
[0035] The clamping mechanism 3 is located on the top of the mounting base 1 and can clamp the entire tray of plastic cups.
[0036] The cutter 4 is mounted on a slide rail 8, and the cutter 4 is slidably connected to the slide rail 8.
[0037] Drive mechanism 2 drives cutter 4 to slide on slide rail 8.
[0038] The drive mechanism 2 includes a drive cylinder 22 and a drive assembly. The fixed end of the drive cylinder 22 is hinged to the mounting base 1. The drive cylinder 22 is hinged to the drive assembly. The drive assembly is hinged to the mounting base 1. The drive assembly is hinged to the cutter 4.
[0039] The drive assembly includes a first connecting rod 21, a second connecting rod 23, and a connector 24. The movable end of the drive cylinder 22 is connected to one end of the connector 24. One end of the first connecting rod 21 is hinged to the mounting base 1, and the other end of the first connecting rod 21 is hinged to one end of the second connecting rod 23. The other end of the second connecting rod 23 is hinged to the cutter 4. The other end of the connector 24 is hinged to the middle of the second connecting rod 23. Specifically, the drive cylinder 22 and the first connecting rod 21 can be arranged parallel to each other. When the drive cylinder 22 pushes the connector 24 to move the second connecting rod 23, the second connecting rod 23 is restricted from moving upward by the cutter 4. Its connection with the cutter 4 can only slide along the slide rail 8, causing the cutter 4 to slide along the slide rail 8, cutting the plastic sheet into whole plastic cups.
[0040] The cutter 4 is slidably connected to the slide rail 8 via a connecting seat. The connecting seat includes a slider 7 and a clamping block. The slider 7 is slidably connected to the slide rail 8. There are two clamping blocks, which are adjustablely mounted on the slider 7. The two clamping blocks clamp the cutter 4 and fix it in place. The slider 7 is connected to the drive mechanism 2.
[0041] Each clamping block has two slots, spaced apart. The slider 7 has connecting holes. The clamping blocks are mounted on the slider 7 using bolts and nuts. One end of the bolt passes through the slot and the connecting hole, and the other end connects to the nut. By using these slots, the distance between the clamping blocks can be adjusted according to different cutters 4, and the cutter 4 can be easily replaced.
[0042] The clamping mechanism 3 includes a bracket 32, a fixed clamp 34, a movable clamp 33, and a lifting cylinder 31. The bracket 32 is mounted on the mounting base 1, and the fixed clamp 34 is fixed on the bracket 32, with a gap between the fixed clamp 34 and the slide rail 8. The movable clamp 33 is slidably connected to the bracket 32, and the lifting cylinder 31 is mounted on the top of the bracket 32, with the movable end of the lifting cylinder 31 facing the mounting base 1. The movable clamp 33 is connected to the movable end of the lifting cylinder 31. Specifically, both the fixed clamp 34 and the movable clamp 33 are elongated plate-like structures. The width of the fixed clamp 34 is greater than the width of the movable clamp 33. The fixed clamp 34 has a movable groove that passes through it. The movable groove is located on the side of the fixed clamp 34 away from the plastic cup forming machine, and the movable groove is offset from the bottom plane of the movable clamp 33. The movable groove extends along the length of the fixed clamp 34, and the cutter 4 passes through the movable groove and protrudes from the top of the fixed clamp 34.
[0043] The bracket 32 includes uprights and a crossbeam. The two uprights are fixed to both sides of the mounting base 1, and the crossbeam is attached to the top of both ends of the two uprights. The lifting cylinder 31 is installed at the bottom of the crossbeam. By setting up such a bracket 32, the lifting cylinder 31 achieves high stability.
[0044] Each of the two uprights has a wheel groove on one side facing each other, and the movable clamp 33 has pulleys at both ends. The two pulleys are connected to the wheel grooves of the two uprights respectively. By setting wheel grooves and pulleys on both sides of the uprights and the movable clamp 33, the movement path of the movable clamp 33 is fixed, ensuring that the movable clamp 33 is aligned with the fixed frame.
[0045] The clamping mechanism 3 also includes a follower assembly 5, which includes a connecting plate 51, a first rod 52, a second rod 54, and a third rod 53. There are two connecting plates 51, which are fixed to both ends of the movable clamp 33. The first rod 52 and the second rod 54 are fixedly connected to the two connecting plates 51, and both ends of the third rod 53 are fixedly connected to the first rod 52 and the second rod 54, respectively. Specifically, both connecting plates 51 can be made of aluminum plates and are fixed to the side of the movable clamp 33 facing the plastic cup molding machine with screws. The outer end of the connecting plate 51 extends towards the plastic cup molding machine and has a connecting hole for the corresponding first rod 52 or second rod 54 to pass through. The connecting hole is then secured by a locking bolt. The first rod 52, the second rod 54, and the third rod 53 are connected by aluminum plates. Two slots are provided on the aluminum plates, and bolts are used to secure the rods passing through the slots. The first rod 52 and the second rod 54 are parallel to each other, the first rod 52 and the third rod 53 are perpendicular to each other, and the second rod 54 and the third rod 53 are perpendicular to each other. With this follower component 5, when the plastic sheet is conveyed between the movable clamp 33 and the fixed frame by the conveying structure of the plastic cup forming machine, the third rod 53 is located between the conveying structure and the clamping mechanism 3 of the plastic cup forming machine, supporting the plastic sheet conveyed by the conveying structure of the plastic cup forming machine, so that the plastic sheet can pass smoothly between the movable clamp 33 and the fixed clamp 34, avoiding the plastic sheet being unable to pass between the movable clamp 33 and the fixed clamp 34 due to its softness. The distance between the first rod 52 and the second rod 54 can be adjusted by using the cooperation of the aluminum plate and the locking bolt, and the relative height of the third rod 53 can also be adjusted, so as to adjust according to different plastic cup products, which has strong versatility.
[0046] The third rod 53 has a receiving pad in the middle, which is a cylindrical structure. Specifically, when the movable clamp 33 and the fixed clamp 34 are clamping the plastic sheet, the position of the third rod 53 is lower than the slide rail 8. When the movable clamp 33 is away from the fixed clamp 34 in the initial state, the position of the third rod 53 is higher than the fixed frame and the top of the cutter 4. The receiving pad located in the middle of the third rod 53 is at the same height as the conveying structure of the plastic cup forming machine, supporting the plastic sheet conveyed by the conveying structure of the plastic cup forming machine, so that the plastic sheet can pass smoothly between the movable clamp 33 and the fixed clamp 34, which facilitates subsequent clamping, positioning and cutting to obtain a whole tray of plastic cups.
[0047] In the above embodiments, the conveying structure of the plastic cup forming machine conveys a tray of plastic cups as a continuous plastic sheet. After the plastic sheet is cut by the cutter 4, a section of plastic sheet is obtained, which is the tray of plastic cups. For example, the length and width of the tray of plastic cups are 1 meter and 0.8 meters, respectively, and the tray of plastic cups is distributed in a rectangular array with multiple plastic cups.
[0048] In use, the movable clamp 33 and the lifting cylinder 31 are in their initial state. The movable clamp 33 is away from the fixed clamp 34, waiting for the plastic sheet to be conveyed between the movable clamp 33 and the fixed clamp 34 by the conveying structure of the plastic cup forming machine. The third rod 53 is driven by the movable clamp 33 to a position at the same height as or slightly lower than the conveying structure of the plastic cup forming machine, and is used to receive the plastic sheet conveyed by the conveying structure of the plastic cup forming machine. The drive cylinder 22 is in the retracted state, and the cutter 4 is at one end of the slide rail 8. The conveying structure of the plastic cup forming machine conveys the plastic sheet to the third rod 53. After the plastic sheet is placed on the upper part, the third rod 53 supports the plastic sheet, preventing it from bending or changing direction. The conveying structure of the plastic cup forming machine continues to convey the plastic sheet between the movable clamp 33 and the fixed clamp 34 until the distance between the movable clamp 33 and the fixed clamp 34 is the width of the entire tray of plastic cups. Then, the conveying stops, the lifting cylinder 31 is activated, and the movable clamp 33 is moved downward to cooperate with the fixed clamp 34 to hold the plastic sheet. The drive cylinder 22 is activated, and the cutter 4 is moved along the slide rail 8. During the movement, the cutter 4 cuts the plastic sheet, completing the cutting of the entire tray of plastic cups.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention.
