Description

Technical Field

[0001] This utility model belongs to the field of plastic packaging bag production technology, and more specifically, it relates to a die-cutting and punching mechanism for plastic packaging bags. Background Technology

[0002] Plastic packaging bags are packaging bags made of plastic and used in the production of various daily necessities. They are widely used in daily life and industrial production, but this convenience brings long-term harm. Commonly used plastic packaging bags are mostly made of polyethylene film, which is non-toxic and therefore suitable for food packaging. Another type of film is made of polyvinyl chloride (PVC). While PVC itself is non-toxic, the additives added to the film, depending on its intended use, often contain substances harmful to the human body and possess a certain degree of toxicity. Therefore, this type of film and the plastic bags made from it are not suitable for food packaging. A search revealed a Chinese patent with authorization publication number CN214187527U, which discloses a punching mechanism for plastic packaging bags, relating to the field of plastic packaging bag production technology. This patent aims to solve the problem that waste generated during punching easily clogs the punching ring cutter in existing plastic packaging bag punching mechanisms, affecting the normal operation of the device. A power rubber roller is installed inside the upper part of the workbench, and the power rubber roller is connected to the workbench via bearings. An upper support is installed at the upper end of the workbench, and the upper support is fixedly connected to the workbench. Adjusting cylinders are installed at both ends of the lower side of the upper support, and adjusting brackets are installed at the lower ends of the adjusting cylinders. The adjusting brackets are fixedly connected to the adjusting cylinders. A driven roller is installed inside the adjusting bracket, and the driven roller adjusting bracket is connected to the adjusting bracket via bearings. A punching cylinder is installed at the upper end of the upper support, and a limit bracket is installed at the lower end of the punching cylinder. The limit bracket is fixedly connected to the punching cylinder.

[0003] In this design, a punching cylinder is installed to drive the punching ring cutter downwards to punch the material, ensuring the integrity of the device's functionality. A top waste spring is installed to push the top waste plate downwards, expelling the waste generated during punching from inside the punching ring cutter and preventing it from clogging the cutter and affecting the normal operation of the device. However, in actual use, due to the relatively simple punching facilities, the device can only process holes of a single diameter on plastic packaging bags.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a die-cutting and punching mechanism for plastic packaging bags in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a die-cutting and punching mechanism for plastic packaging bags, thereby resolving the issues raised in the background art.

[0006] The purpose and effect of this utility model's plastic packaging bag die-cutting and punching mechanism are achieved through the following specific technical means:

[0007] A die-cutting and punching mechanism for plastic packaging bags includes a worktable and a roller conveyor. The top of the worktable is equipped with a top frame, and the inner top of the top frame is equipped with a punching mechanism. The punching mechanism includes a frame, several cylinders, a first ring cutter, a second ring cutter, and a third ring cutter. The several cylinders are respectively installed at the inner bottom of the frame, and the output ends of the several cylinders pass through the frame and are connected to the tops of the first, second, and third ring cutters. The apertures of the first, second, and third ring cutters increase sequentially. The roller conveyor is fixedly installed on one side of the worktable, and its top is provided with several pairs of holes, which are respectively located directly below the first, second, and third ring cutters.

[0008] Furthermore, the workbench includes a platform and a support column, with the support column connected to both sides of the top of the platform, and a hydraulic cylinder installed inside the platform near the support column.

[0009] Furthermore, the top frame includes a "U"-shaped frame and slots. Slots are provided on both sides of the top of the "U"-shaped frame. The interiors of the two slots are slidably connected to one end of the support column. The output end of the hydraulic cylinder is connected to one side of the interior of the slots.

[0010] Furthermore, a material receiving mechanism is provided at the bottom of each of the aforementioned holes. The material receiving mechanism includes a material receiving cylinder, a sealing plug, a filter element, and an air valve. The bottom of the material receiving cylinder is threadedly connected to the sealing plug, and the bottom of the sealing plug is connected to the air valve.

[0011] Furthermore, the top of the air valve extends into the interior of the sealing plug and is filled with a filter element.

[0012] Furthermore, the idler conveyor includes a body and a power rubber roller. The top surface of the body is provided with several grooves, and the power rubber roller is rotatably connected to the interior of each of the grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This plastic packaging bag die-cutting and punching mechanism, through the cooperation of a punching mechanism, a hole alignment mechanism, a top frame, and a roller conveyor, enables the mechanism to process holes of different diameters in plastic packaging bags. The top frame provides installation space for the punching mechanism, and the top frame is pushed by the output end of a hydraulic cylinder, causing the top frame to move the punching mechanism up and down until the bottom end of the punching mechanism is in contact with the surface of the plastic packaging bag. Then, the output end of a pneumatic cylinder pushes one of the ring cutters, completing the punching operation. The dimensional differences between the first, second, and third ring cutters allow different cutters to extend into different hole alignments, thus processing holes of different diameters. This invention has a simple and reasonable structure, novel design, and is easy and convenient to operate. It can process holes of different diameters and has high practical value.

[0023] Example:

[0024] As attached Figure 1To be continued Figure 5 As shown:

[0025] This utility model provides a die-cutting and punching mechanism for plastic packaging bags, including a workbench 100 and a roller conveyor 300. A top frame 200 is provided at the top of the workbench 100, and a punching mechanism 600 is provided inside the top of the top frame 200. The punching mechanism 600 includes a frame 6001, several cylinders 6002, a first ring cutter 6003, a second ring cutter 6004, and a third ring cutter 6005. The several cylinders 6002 are respectively installed at the bottom of the inner part of the frame 6001, and the output ends of the several cylinders 6002... The holes 6001 pass through the frame and are connected to the top of the first ring cutter 6003, the second ring cutter 6004, and the third ring cutter 6005. The diameters of the holes of the first ring cutter 6003, the second ring cutter 6004, and the third ring cutter 6005 increase sequentially. The roller conveyor 300 is fixedly installed on one side of the workbench 100. The top of the roller conveyor 300 is provided with several pairs of holes 400, which are located directly below the first ring cutter 6003, the second ring cutter 6004, and the third ring cutter 6005.

[0026] The workbench 100 includes a platform body 1001 and a support column 1002. The top two sides of the platform body 1001 are connected to the support column 1002 respectively. A hydraulic cylinder 500 is installed inside the platform body 1001 near the support column 1002. The output end of the hydraulic cylinder 500 pushes the slot 2002, so that the "U" shaped frame 2001 can be adjusted in height at the top of the support column 1002.

[0027] The top frame 200 includes a U-shaped frame 2001 and a slot 2002. The slots 2002 are respectively provided on both sides of the top of the U-shaped frame 2001. The interior of the two slots 2002 is slidably connected to one end of the support column 1002. The output end of the hydraulic cylinder 500 is connected to one side of the interior of the slot 2002. Through the cooperation between the slots 2002 and the support column 1002, the lifting and lowering movement of the U-shaped frame 2001 is more stable.

[0028] Among them, several pairs of holes 400 are respectively provided with a material receiving mechanism 700 at their bottom ends. The material receiving mechanism 700 includes a material receiving cylinder 7001, a sealing plug 7002, a filter element 7003, and an air valve 7004. The bottom end of the material receiving cylinder 7001 is threadedly connected to the sealing plug 7002, and the bottom end of the sealing plug 7002 is connected to the air valve 7004. Through the connection and use of the air valve 7004, it is easy to connect to the air pump, so that a negative pressure is formed inside the material receiving cylinder 7001, thereby completing the effect of sucking up waste materials.

[0029] The top of the air valve 7004 extends into the interior of the sealing plug 7002 and is filled with a filter element 7003. The installation and use of the filter element 7003 facilitates the filtration of impurities inside the receiving cylinder 7001.

[0030] The idler roller conveyor 300 includes a body 3001 and a power rubber roller 3002. The top surface of the body 3001 is provided with several grooves, and the power rubber roller 3002 is rotatably connected to the inside of the grooves. By installing and using the power rubber roller 3002, it is convenient to convey plastic packaging bags on the body 3001.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When using this type of plastic packaging bag die-cutting and punching mechanism, firstly, check whether the connections of the mechanism are secure. After ensuring they are intact, place the mechanism in the designated position. The top frame 200 provides installation space for the punching mechanism 600. Then, by activating the hydraulic cylinder 500, its output end pushes the top frame 200, causing the top frame 200 to move the punching mechanism 600 up and down until the bottom of the punching mechanism 600 is in contact with the surface of the plastic packaging bag. Next, by activating the cylinder 6002, its output end pushes one of the ring cutters, causing the mechanism to complete the punching work. Then, the first ring cutter 6003, the second ring cutter 6004, and the third ring cutter... The size difference between the blades 6005 allows different ring blades to extend into different holes 400, thus producing holes of different diameters. The output end of the hydraulic cylinder 500 pushes the slot 2002, allowing the "U"-shaped frame 2001 to be raised and lowered at the top of the support column 1002. The cooperation between the slot 2002 and the support column 1002 makes the raising and lowering of the "U"-shaped frame 2001 more stable. At the same time, the connection of the air valve 7004 facilitates the connection with the air pump, creating negative pressure inside the receiving cylinder 7001 to achieve the effect of sucking up waste materials. The installation of the filter element 7003 facilitates the filtration of impurities inside the receiving cylinder 7001.
