Utility Model Content

[0005] This utility model discloses a punching device for processing plastic packaging bags, which aims to solve the technical problem of poor fixing and pressing effect of existing packaging bag punching devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A punching device for processing plastic packaging bags includes a base and a top plate, with a vertical plate fixedly installed between the base and the top plate; The top plate has an embedded mounting frame on its upper surface. A rotating opening is provided through the back of the mounting frame. A first operating rod is rotatably connected to the inner wall of the rotating opening. The front end of the first operating rod extends into the interior of the mounting frame and is fixedly connected to a screw. A first threaded block is threadedly connected to the surface of the screw. A hydraulic rod is installed on the lower surface of the first threaded block. A connecting plate is fixedly installed on the telescopic end of the hydraulic rod. A punch is fixedly installed on the lower surface of the connecting plate. Two symmetrical pressure plates are provided below the connecting plate, and two symmetrical connecting rods are provided on the upper surface of the pressure plates. The surface of the connecting plate is provided with sliding holes that are adapted to the connecting rods. A spring is sleeved on the surface of the connecting rod, and the upper and lower ends of the spring are fixedly connected to the lower surface of the connecting plate and the upper surface of the pressure plate, respectively.

[0007] In a preferred embodiment, the lower surface of the pressure plate is provided with an anti-slip pad, which is made of wear-resistant rubber material.

[0008] The anti-slip pads can improve the stability of the pressure plate when pressing against the packaging bag.

[0009] In a preferred embodiment, the upper surface of the first threaded block is provided with a guide slider, and the inner top wall of the mounting frame is provided with a guide groove for the guide slider to slide.

[0010] By setting a guide slider, the first threaded block can drive the connecting plate and the punch to move in a specific direction through the rotation of the screw.

[0011] In a preferred embodiment, the front of the base is provided with a collection groove, and a collection box is slidably connected inside the collection groove via a slide rail. The upper surface of the base is provided with a discharge strip that extends into the collection groove.

[0012] The collection box allows debris generated during punching to be pushed into it, facilitating subsequent cleaning.

[0013] In a preferred embodiment, the front of the base is rotatably connected to a limiting block for restricting the collection box via a rotating seat.

[0014] In a preferred embodiment, the front of the vertical plate is provided with a mounting groove, and the right side of the vertical plate is provided with a mounting opening that extends into the mounting groove. A second operating rod is rotatably connected to the inner wall of the mounting opening. The left end of the second operating rod extends into the interior of the mounting groove and is fixedly connected to a bidirectional threaded rod. Two symmetrical second threaded blocks are threadedly connected to the surface of the bidirectional threaded rod, and a limit strip is fixedly connected to the front of each of the two second threaded blocks.

[0015] The limiting strip ensures that the packaging bag is always positioned below the punch during placement.

[0016] In a preferred embodiment, a limiting slider is provided on the back of the second threaded block, and a limiting groove is provided on the inner rear wall of the mounting groove for the limiting slider to slide.

[0017] By setting a limit slider, the second threaded block can drive the limit strip to move in a specific direction through the rotation of the bidirectional threaded rod.

[0018] As can be seen from the above, the punching device for processing plastic packaging bags provided by this utility model has the following technical effects.

[0019] Firstly, the hydraulic rod moves the punch downwards via the connecting plate. The downward movement of the connecting plate, through the connecting rod and spring, causes the pressure plate to press against the surface of the packaging bag. As the connecting plate continues to move downwards, its pressure, through the pressure plate, stably presses the packaging bag onto the base surface until the punch moves down and completes the punching operation. This avoids the packaging bag from shifting or tilting due to unstable pressing. During this process, the debris generated during punching falls into the collection box through the material dropper, facilitating subsequent cleaning work.

[0020] Secondly: Place the packaging bag to be punched between the two limiting strips. Under the guidance of the limiting strips, the punch can be positioned in the center of the packaging bag. During this period, by rotating the second operating rod, the bidirectional threaded rod is rotated. The two second threaded blocks, under the rotation of the bidirectional threaded rod, drive the two limiting strips to move closer or in opposite directions. The placement distance between the two limiting strips can be adjusted according to the size of different packaging bags.

[0021] Thirdly: When it is necessary to adjust the punching position on the surface of the packaging bag, rotate the first operating lever to drive the screw to rotate. The first threaded block drives the hydraulic rod and the connecting plate to move back and forth in a directional manner through the rotation of the screw, so that the punching position can be adjusted.

[0031] The upper surface of the first threaded block 6 is provided with a guide slider 13, and the inner top wall of the mounting frame 4 is provided with a guide groove for the guide slider 13 to slide. Under the guidance of the guide slider 13, the first threaded block 6 can drive the connecting plate 8 and the punch 9 to move in a directional manner through the rotation of the screw 5.

[0032] Two symmetrical pressure plates 10 are provided below the connecting plate 8. Two symmetrical connecting rods 11 are provided on the upper surface of the pressure plate 10. The surface of the connecting plate 8 is provided with sliding holes that are compatible with the connecting rods 11. A spring 12 is sleeved on the surface of the connecting rod 11. The upper and lower ends of the spring 12 are fixedly connected to the lower surface of the connecting plate 8 and the upper surface of the pressure plate 10, respectively.

[0033] The lower surface of the pressure plate 10 is provided with an anti-slip pad, which is made of wear-resistant rubber material. The anti-slip pad can improve the stability of the pressure plate 10 when pressing the packaging bag.

[0034] Reference Figure 1 , Figure 2 and Figure 4In a preferred embodiment, a collection groove is provided on the front of the base 1, and a collection box 14 is slidably connected inside the collection groove via a slide rail. A material discharge slot 15 is provided on the upper surface of the base 1, which extends into the collection groove. By setting up the collection box 14, the debris generated during punching can be pushed into the collection box 14, which facilitates subsequent cleaning work.

[0035] The front of the base 1 is rotatably connected to a limiting block 16 for limiting the collection box 14 via a rotating seat.

[0036] Reference Figure 1 and Figure 5 In a preferred embodiment, the front of the vertical plate 3 is provided with an installation groove, and the right side of the vertical plate 3 is provided with an installation opening that extends into the installation groove. The inner wall of the installation opening is rotatably connected to a second operating rod. The left end of the second operating rod extends into the installation groove and is fixedly connected to a bidirectional threaded rod 17. The surface of the bidirectional threaded rod 17 is threaded with two symmetrical second threaded blocks 18. The front of each of the two second threaded blocks 18 is fixedly connected to a limiting strip 19. By setting the limiting strip 19, the packaging bag can always be located below the punch 9 when placed.

[0037] The second threaded block 18 is provided with a limiting slider 20 on its back side.

[0038] Working principle: During use, the packaging bag to be punched is placed between the two limiting plates 19. Guided by the positioning of the limiting plates 19, the punch 9 is positioned in the center of the packaging bag. During this process, rotating the second operating lever drives the bidirectional threaded rod 17 to rotate. The two second threaded blocks 18, under the rotation of the bidirectional threaded rod 17, respectively drive the two limiting plates 19 to move closer together or in opposite directions. The placement distance between the two limiting plates 19 can be adjusted according to the size of different packaging bags. During punching, the hydraulic rod 7 moves through the connecting plate 8 to drive the punch 9 downward. The downward movement of the connecting plate 8 is transmitted through the connecting plate 8 to the punch 9. The connecting rod 11 and spring 12 drive the pressure plate 10 to press against the surface of the packaging bag in advance. As the connecting plate 8 continues to move down, the pressure of the pressure plate 10 stabilizes the packaging bag on the surface of the base 1 until the punch 9 moves down to complete the punching operation. During this period, the debris generated by punching falls into the collection box 14 through the discharge strip 15, which facilitates subsequent cleaning work. When it is necessary to adjust the punching position on the surface of the packaging bag, the first operating rod is rotated to drive the screw 5 to rotate. The first threaded block 6 drives the hydraulic rod 7 and the connecting plate 8 to move back and forth in a directional manner through the rotation of the screw 5, so that the punching position can be adjusted.
