Description

Technical Field

[0001] This utility model relates to the technical field of packaging equipment, and in particular to a plastic bag die-cutting machine. Background Technology

[0002] In today's rapidly developing consumer market, plastic packaging products are ubiquitous. Among them, plastic bags, with their advantages of being lightweight, inexpensive, and highly malleable, have become an indispensable form of packaging in various commodity circulation processes. Currently, all these diverse plastic bags on the market require die-cutting machines to complete the crucial forming process. For example, Chinese patent document CN114368044A discloses a die-cutting machine for cutting a preset film sheet from a raw film. The machine includes a frame and a mold support, the mold support being used to hold the raw film. A cutting die is disposed on the frame, and the cutting die has an initial position and a cutting position relative to the mold support. An adjustment mechanism is disposed on the cutting die, and a drive mechanism is disposed on the frame. The drive mechanism is connected to the adjustment mechanism. The drive mechanism drives the adjustment mechanism to move, thereby causing the cutting die to reciprocate between the initial position and the cutting position, so that the cutting die cuts the raw film on the mold support. The adjustment mechanism is used to change the initial position and the cutting position of the cutting die, thus enabling the change of the initial position and the cutting position of the cutting die.

[0003] However, existing plastic bag die-cutting machines have the following shortcomings in actual use: the rotating rollers on their separating mechanism cause the pre-set film to be thrown from the original film onto the conveyor belt, resulting in the pre-set films piling up and becoming messy on the conveyor belt. This necessitates that the pre-set films be tidied up before the subsequent packaging process can begin, leading to low work efficiency. In view of this, the plastic bag die-cutting machine of this application is proposed. Utility Model Content

[0031] like Figure 1As shown, in one embodiment, a plastic bag die-cutting machine 1 includes a frame 10 and a film-peeling assembly 20. A film-supporting plate 11 is mounted on the frame 10. The film-peeling assembly 20 includes a material placement seat 21, a push plate 22, a film-cutting plate 23, a push rod 24, a material-pushing drive 25, and a material-pressing drive 26. The material placement seat 21 is mounted on the frame 10 and has a sliding groove 211. The push plate 22 is slidably disposed within the sliding groove 211. The material-pushing drive 25 is mounted on the material placement seat 21, and its output end is connected to the push plate 22, so that the material-pushing drive 25 drives the material to move. The push plate 22 slides in the material groove 211, the pressing drive 26 is set on the frame 10, the film cutting plate 23 is slidably set on the frame 10, and the film cutting plate 23 is located above the film supporting plate 11. One end of the film cutting plate 23 is connected to the output end of the pressing drive 26 so that the pressing drive 26 drives the film cutting plate 23 to engage with the film supporting plate 11. The position of the push rod 24 is adjustable on the film cutting plate 23. The film cutting plate 23 drives the push rod 24 to approach the material groove 211. The push rod 24 pushes the preset film into the material groove 211, and the push plate 22 pushes the preset film out of the material groove 211.

[0032] It should be noted that the film-supporting plate 11 is mounted on the frame 10 and is used to support the original film. The film-cutting plate 23 is slidably mounted on the frame 10 and is located above the film-supporting plate 11. The film-cutting plate 23 and the film-supporting plate 11 are interlocked to cut the original film, so that the cut part of the original film is pre-set with film. Further, the pressing drive 26 is mounted on the frame 10. The pressing drive 26 can be a crank-connecting rod mechanism. The crank-connecting rod mechanism drives the crank to rotate through the motor 251. The rotational motion of the crank is converted into the reciprocating linear motion of the connecting rod, which then drives the film-cutting plate 23 to move up and down. The pressing drive 26 can also be a cam structure. The cam head drives the cam to rotate through the motor 251. The profile curve of the cam contacts the follower (such as a roller or plate). As the cam rotates, the follower moves up and down according to the law of the cam profile curve, thereby driving the film-cutting plate 23 to move up and down. The cutting plate 23 is connected to the output end of the pressing drive 26. The pressing drive 26 can drive the cutting plate 23 to move up and down relative to the frame 10, so that the cutting plate 23 reciprocates up and down to engage or disengage with the film receiving plate 11, thereby enabling the cutting plate 23 to continuously punch the original film. Further, a material placement seat 21 is disposed on the frame 10, and the material placement seat 21 is located on the side of the film receiving plate 11 in the film exit direction, and the material placement seat 21 is close to the film receiving plate 11. The material placement seat 21 is used to receive the pre-cut film on the original film. Further, a sliding groove 211 is provided on the material placement seat 21. The opening direction of the sliding groove 211 is perpendicular to the film exit direction of the film receiving plate 11, so that the pre-cut film can pass over the sliding groove 211. Further, one end of the push rod 24 is adjustablely disposed on the cutting plate 23, while the other end of the push rod 24 faces the sliding groove 211. When the cutting plate 23 moves up and down, it will drive the push rod 24 away from the cutting plate 23 to reciprocate up and down into or away from the sliding groove 211. After the original film passes the receiving plate 11, the original film will drive the pre-cut film to move above the sliding groove 211, so that the uncut part of the original film moves to the receiving plate 11. The pressing drive 26 will drive the cutting plate 23 to make the next cut, and at the same time drive the push rod 24 to extend downward into the sliding groove 211, so that the push rod 24 pushes the pre-cut film to detach from the original film. The push rod 24 will continue to push the pre-cut film into the sliding groove 211. After repeating this process multiple times, the push rod 24 will push multiple pre-cut films to a position in the sliding groove 211, so that multiple pre-cut films will be neatly stacked in the sliding groove 211.

[0033] It should be noted that the pusher drive 25 is mounted on the material placement seat 21, and the pusher plate 22 is slidably mounted in the sliding groove 211. One end of the pusher plate 22 is connected to the output end of the pusher drive 25, so that the pusher drive 25 can drive the pusher plate 22 to slide back and forth between the two ends of the sliding groove 211. When the pusher rod 24 pushes multiple preset films into the sliding groove 211 to be neatly stacked, the pusher drive 25 will drive the pusher plate 22 to push the multiple preset films neatly stacked in the sliding groove 211 to slide within the sliding groove 211. Furthermore, the film peeling assembly 20 also includes a conveyor belt 27, which is mounted on the frame 10. The conveying direction of the conveyor belt 27 is consistent with the film exit direction of the film support plate 11. One end of the sliding groove 211 is an open structure. Since the opening direction of the sliding groove 211 is perpendicular to the film exit direction of the film support plate 11, the opening at one end of the sliding groove 211 can be connected to the conveyor belt 27. When the pusher plate 22 pushes the multiple pre-stacked films neatly stacked in the sliding groove 211 towards the opening, the films can slide from the opening onto the conveyor belt 27. Thus, when the conveyor belt 27 transports the films to the next process, the next process does not need to rearrange or stack them again; they can be directly bundled and packaged, improving production efficiency. In one embodiment, depending on the packaging requirements of the next process, for example, if a bundle of twenty films is required, the pressing drive 26 can drive the film cutting plate 23 to cut twenty times. After the pusher rod 24 pushes the twenty films into the sliding groove 211, the pusher drive 25 then drives the pusher plate 22 to push the twenty films onto the conveyor belt 27. Then, the pressing drive 26 continues to repeat the above actions. Thus, the number of alternations between the film cutting plate 23 and the pusher plate 22 can be adjusted according to the packaging quantity requirements of the next process, thereby improving production efficiency.

[0034] like Figure 2 , Figure 4 As shown, in one embodiment, the push rod 24 includes a push column 241 and a push column 242. One end of the push column 241 is adjustablely positioned on the film cutting plate 23, and the push column 242 is positioned on the end of the push column 241 away from the film cutting plate 23. The push column 242 is used to push the preset film.

[0035] It should be noted that one end of the top post 241 is adjustablely positioned on the cutting plate 23, and the top post 241 is located above the material placement seat 21. The end of the top post 241 away from the cutting plate 23 faces the material chute 211. Furthermore, the pusher 242 is positioned on the end of the top post 241 away from the cutting plate 23. When the original film moves above the material placement seat 21, and the pre-cut film is positioned above the sliding groove 211, the waste material around the pre-cut film will be located at the edge of the sliding groove 211. When the cutting plate 23 moves up and down, the top post 241 drives the pusher 242 to abut against the pre-cut film. The pusher 242 pushes the pre-cut film off the original film and into the sliding groove 211. Thus, when the cutting plate 23 moves up and down repeatedly, each time the cutting plate 23 drives the top post 241 downwards towards the material placement seat 21, it will drive the pusher 242 to push a pre-cut film into the sliding groove 211, so that multiple pre-cut films are neatly stacked in the sliding groove 211. It should be noted that the push post 242 is positioned at the end of the top post 241 that is away from the film cutting plate 23, and with the connection point with the top post 241 as the center, both ends of the push post 242 extend relative to the sides of one end of the top post 241, making the push rod 24 tend to be a T-shaped structure. However, the distance that one end of the push post 242 extends relative to one end of the top post 241 is greater than the distance that the other end of the push post 242 extends relative to one end of the top post 241. In this way, both ends of the push post 242 can abut against the two sides of the preset film that are connected to the original film, so that the preset film can be better separated from the original film.

[0036] like Figure 4 As shown, in one embodiment, there is an angle between the push post 242 and the top post 241.

[0037] It should be noted that there is an angle between the push post 242 and the top post 241, and the angle is greater than 90 degrees but not equal to 90 degrees. This causes the push post 242 to abut against the preset film. The end of the push post 242 that extends a longer distance from the end of the top post 241 abuts against the connection between the preset film and the original film first, so that the edge connecting the preset film and the original film is separated first. Then, the end of the push post 242 that extends a shorter distance from the end of the top post 241 abuts against the other opposite connection between the preset film and the original film, so that the other opposite connection between the preset film and the original film is separated. In this way, one end of the preset film is separated from the original film first, and then the other end of the preset film is separated from the original film, so that the preset film can be quickly separated from the original film.

[0038] like Figure 2 As shown, in one embodiment, an adjustment seat is provided on the film cutting plate 23, and the position of the top rod 24 is adjustablely provided on the adjustment seat.

[0039] It should be noted that the adjusting seat includes a fixed block 231 and a movable block 232. The fixed block 231 is disposed on the cutting plate 23, and the movable block 232 is slidably disposed on the fixed block 231. An adjusting hole 2311 is provided on the fixed block 231. One end of the top post 241 passes through the adjusting hole 2311 and is connected to the movable block 232. The adjusting hole 2311 is an elongated hole structure. The end of the top post 241 away from the push post 242 passes through the adjusting hole 2311 and extends out from the end of the movable block 232 away from the fixed block 231. Furthermore, a retaining ring 2411 is provided on the top post 241. When the top post 241 passes through the adjustment hole 2311, the retaining ring 2411 will abut against the end of the fixed block 231 away from the moving block 232. In this way, one end of the top post 241 passes through the adjustment hole and extends out from the end of the moving block 232 away from the fixed block 231, and is screwed in by a nut, so that the position of the top rod 24 is adjustable on the film cutting plate 23. In one embodiment, multiple adjustment holes 2311 are provided on the fixed block 231, and multiple top rods 24 are also provided. The end of each top rod 24 away from the push post 242 passes through each adjustment hole 2311 in turn, and extends out from the end of the moving block 232 away from the fixed block 231, and is screwed in by a nut. In this way, when the film cutting plate 23 moves downward, the film cutting plate 23 will drive multiple top rods 24 to push multiple preset films on the original film to slide into the material groove 211.

[0040] like Figure 3 As shown, in one embodiment, the pusher drive 25 includes a motor 251, a drive wheel 252, a driven wheel 253, and a belt 254. The motor 251 is mounted on the material placement seat 21, the drive wheel 252 is sleeved on the output shaft of the motor 251, the driven wheel 253 is rotatably mounted on the material placement seat 21, and the belt 254 is sleeved on the drive wheel 252 and the driven wheel 253 respectively.

[0041] It should be noted that the pusher drive component 25 also includes a clamping block 255, which is mounted on the belt 254. One end of the pusher plate 22 is connected to the clamping block 255, so that the clamping block 255 drives the pusher plate 22 to slide back and forth relative to the sliding groove 211, so that the pusher plate 22 pushes the neatly stacked preset film to slide from the sliding groove 211 to the conveyor belt 27.

[0042] like Figures 2 to 3 As shown, in one embodiment, a sliding hole 2111 is provided on the sliding groove 211, and a slider 221 is provided on the push plate 22, and the slider 221 is engaged with the sliding hole 2111.

[0043] It should be noted that a slider 221 is provided on one end of the push plate 22 near the bottom wall of the sliding groove 211, and a sliding hole 2111 is provided on the bottom wall of the sliding groove 211. The opening direction of the sliding hole 2111 is diffracted from one end of the sliding groove 211 to the other end of the sliding groove 211. The slider 221 engages with the sliding hole 2111, so that the push plate 22 can slide smoothly in the sliding groove 211.

[0044] like Figure 1 As shown, in one embodiment, the film peeling assembly 20 further includes a cover plate 28, which is disposed on the material placement seat 21.

[0045] It should be noted that the cover plate 28 is disposed on the material placement seat 21 and is located above the material pushing drive member 25, so that the material placement seat 21 and the film support plate 11 are on the same horizontal plane.

[0046] like Figure 1 As shown, in one embodiment, a baffle 271 is provided on the conveyor belt 27. The baffle 271 is located on the side of the conveyor belt 27 away from the material chute 211, and the baffle 271 is aligned with the outlet of the material chute 211. In this way, multiple neatly stacked pre-set films sliding out of the material chute 211 can fall neatly onto the conveyor belt 27, preventing the pre-set films from slipping off the conveyor belt 27.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
