Description

Technical Field

[0001] This utility model relates to the field of flexible film packaging bag processing technology, specifically a cutting device for flexible film packaging bags. Background Technology

[0002] Packaging bags are bags that can be used to package various items and goods, and can protect items and goods from external environmental pollution and damage. Packaging bags can be divided into plastic packaging bags, linen packaging bags, etc. Among them, soft film packaging bags are packaging bags made of flexible materials (such as polyethylene, polypropylene, aluminum foil, etc.).

[0003] When processing flexible film packaging bags, a cutting device is usually used to cut the flexible film packaging bags. Since there is no fixing mechanism above the cutting device, it is easy to cause wrinkles in the flexible film packaging bags when cutting them directly with the cutting blade, which leads to poor cutting effect and makes it difficult to carry out the cutting work normally. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for flexible film packaging bags to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for soft film packaging bags, comprising a workbench, a cutting groove being provided at the top of the workbench, a support being fixedly connected to the top of the workbench, a cylinder being fixedly connected to the top of the support, a cutting blade being fixedly connected to the output end of the cylinder, a fixing mechanism being provided at the top of the workbench, and a movable groove being provided at the top of the workbench.

[0006] As a further preferred embodiment of this technical solution, the inner wall of the movable groove is slidably connected to a movable plate, the top of the movable plate is fixedly connected to a top plate, the top of the top plate is threadedly connected to a lead screw, and the bottom of the lead screw is rotatably connected to a pressing block.

[0007] As a further preferred embodiment of this technical solution, a base plate is fixedly connected to the outer wall of the movable plate, the base plate being directly below the pressing block, and a shell is fixedly connected to the outer wall of the worktable, with bidirectional bolts penetrating and rotatably connected to the inner wall of the shell.

[0008] As a further preferred embodiment of this technical solution, the outer surface of the bidirectional bolt is threaded through and connected to two movable blocks, the top end of each movable block is fixedly connected to a connecting arm, and the end of the connecting arm away from the movable block is fixedly connected to the outer surface of the movable plate.

[0009] As a further preferred embodiment of this technical solution, the outer surface of the cutting blade is provided with an auxiliary mechanism, and an extension block is fixedly connected to the outer surface of the cutting blade.

[0010] As a further preferred embodiment of this technical solution, the top end of the extension block is provided with a through hole, the inner wall of the through hole is slidably connected to a movable rod, the bottom end of the movable rod is fixedly connected to a positioning plate, and the top end of the positioning plate is fixedly connected to a spring.

[0011] As a further preferred embodiment of this technical solution, the top end of the spring is fixedly connected to the bottom end of the extension block, and the top end of the movable rod is fixedly connected to a limit plate.

[0012] This utility model provides a cutting device for flexible film packaging bags, which has the following advantages: (1) This utility model uses the rotation of the screw to drive the pressing block to move downward. The pressing block fixes the soft film packaging bag above the base plate. The rotation of the bidirectional bolt causes the two moving blocks to move in opposite directions. The movement of the moving blocks causes the connecting arm to move. The movement of the connecting arm causes the movable plate to move inside the movable groove. The movement of the movable plate flattens the fixed soft film packaging bag, thereby removing the wrinkles on the surface of the soft film packaging bag, which is convenient for later cutting.

[0013] (2) In this utility model, the positioning plate contacts the surface of the soft film packaging bag. The positioning plate is squeezed and drives the movable rod to move upward inside the through hole. The positioning plate will squeeze the spring, so that the spring is in a compressed state. The spring relies on its own elasticity to buffer the impact force generated by the cutting knife and applies downward pressing force to the positioning plate, further driving the positioning plate to fix the soft film packaging bag and keep the soft film packaging bag stable during cutting.

[0018] The inner wall of the movable groove 61 is slidably connected to a movable plate 62, the top of the movable plate 62 is fixedly connected to a top plate 63, the top of the top plate 63 is threadedly connected to a lead screw 64, and the bottom of the lead screw 64 is rotatably connected to a pressing block 65.

[0019] The position of the pressing block 65 is adjusted by rotating the lead screw 64.

[0020] Among them, the outer wall of the movable plate 62 is fixedly connected to the base plate 66, which is located directly below the pressing block 65. The outer wall of the worktable 1 is fixedly connected to the outer shell 67, and the inner wall of the outer shell 67 is rotatably connected to the bidirectional bolt 68.

[0021] The two-way bolt 68, when rotated, can drive the two moving blocks 69 to move in opposite directions.

[0022] Among them, the outer surface of the bidirectional bolt 68 is penetrated and threadedly connected to two moving blocks 69. The top of the moving block 69 is fixedly connected to a connecting arm 610, and the end of the connecting arm 610 away from the moving block 69 is fixedly connected to the outer surface of the movable plate 62.

[0023] By moving block 69, the movable plate 62 is used to remove wrinkles from the surface of the soft film packaging bag.

[0024] The outer surface of the cutting blade 5 is provided with an auxiliary mechanism 7, and an extension block 71 is fixedly connected to the outer surface of the cutting blade 5.

[0025] The auxiliary mechanism 7 can further press and fix the soft film packaging bag.

[0026] The extension block 71 has a through hole 72 at its top, a movable rod 75 is slidably connected to the inner wall of the through hole 72, a positioning plate 74 is fixedly connected to the bottom end of the movable rod 75, and a spring 73 is fixedly connected to the top end of the positioning plate 74.

[0030] This utility model provides a cutting device for flexible film packaging bags, the specific working principle of which is as follows: In use, place the soft film packaging bag to be cut above the base plates 66 on both sides. Rotate the lead screws 64 on both sides in sequence. The rotation of the lead screws 64 causes the pressing blocks 65 to move downwards, fixing the soft film packaging bag above the base plates 66. Rotate the bidirectional bolts 68. The rotation of the bidirectional bolts 68 causes the two moving blocks 69 to move in opposite directions. The movement of the moving blocks 69 causes the connecting arm 610 to move. The movement of the connecting arm 610 causes the movable plate 62 to move inside the movable groove 61. The movement of the movable plate 62 flattens the fixed soft film packaging bag, thereby removing the soft film packaging. The pleats on the surface of the bag facilitate subsequent cutting. When cutting the soft film packaging bag, the cutting blade 5 moves downward, and the positioning plate 74 first contacts the surface of the soft film packaging bag. The positioning plate 74 is squeezed, which drives the movable rod 75 to move upward inside the through hole 72. The positioning plate 74 also squeezes the spring 73, so that the spring 73 is in a compressed state. The spring 73 uses its own elasticity to buffer the impact force generated by the cutting blade 5 and applies downward pressing force to the positioning plate 74, further driving the positioning plate 74 to fix the soft film packaging bag and maintain the stability of the soft film packaging bag during cutting.
