Description

Technical Field

[0001] This utility model relates to the field of container bag cutting technology, and in particular to an automatic container bag cutting device. Background Technology

[0002] FIBCs, also known as flexible FIBCs, ton bags, or space bags, are a type of container unit. They can be used with forklifts for transporting powdery, granular, or lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals. During processing, FIBCs require cutting. Automatic FIBC cutting devices are specialized equipment for automating the cutting of FIBCs (also called flexible FIBCs, ton bags, or space bags). The main function of this device is to precisely cut large rolls or blocks of FIBC material according to set dimensions and requirements to produce standardized FIBCs that meet the packaging needs of different industries.

[0003] During the cutting process of FIBCs, since the materials of FIBCs are different, when cutting large areas of FIBC material or thick FIBC material, different cutting blades need to be changed. Changing cutting blades is time-consuming and laborious, which affects cutting efficiency. Utility Model Content

[0026] In order to solve the problems existing in the background art, this application proposes the following technical solution: an automatic cutting device for container bags.

[0027] The specific technical solution includes an operating table 1, on one side of which a concave plate 2 is fixedly installed; a cutting assembly 3, which is located on one side of the operating table 1, and includes a connecting plate 31, a serrated blade 32, a toothed plate 33, and a cutting flat blade 34. The serrated blade 32 is fixedly installed on the connecting plate 31, the toothed plate 33 is slidably connected inside the serrated blade 32, and the cutting flat blade 34 is fixedly installed on one side of the toothed plate 33; and an adjustment mechanism 4, which is located on one side of the connecting plate 31 and is used to adjust the movement of the toothed plate 33.

[0028] One end of the movable plate 42 is fixedly installed on the horizontal plate 41. The sliding block 44 is slidably connected in the groove. One end of the threaded rod 43 is rotatably connected to the sliding block 44, and the movable plate 42 is threadedly connected to the threaded rod 43. The rotating handle 45 is fixedly installed on the other end of the threaded rod 43. The driving cylinder 46 is fixedly installed on one side of the connecting plate 31, and the output end of the driving cylinder 46 passes through the groove and is fixedly installed on the sliding block 44. The threaded rod 43 can drive the movable plate 42 to move to one side.

[0029] An electric telescopic rod 5 is fixedly installed on one side of the concave plate 2. A slot is opened on one side of the connecting plate 31, and a slider 6 is slidably connected in the slot. The other end of the electric telescopic rod 5 is fixedly installed on the slider 6. A traction groove is opened on one side of the concave plate 2, and a traction block 7 is slidably connected in the traction groove. A hydraulic cylinder 8 is fixedly installed on one side of the traction block 7, and the other end of the hydraulic cylinder 8 is fixedly installed on the connecting plate 31. The electric telescopic rod 5 can drive the cutting blade 34 set on one side of the connecting plate 31 to cut the container bag with a large area.

[0030] A placement plate 9 is fixedly installed on one side of the operating table 1. An installation cavity is opened on one side of the placement plate 9. A movable plate 10 is slidably connected in the installation cavity.

[0031] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0032] In use, place the container bag on the operating table 1. The elasticity of the return spring 11 allows the pressure roller 14 inside the clamping plate 13 to pull the container bag, preventing wrinkles. Then, activate the electric telescopic rod 5, causing the connecting plate 31 at one end to move downwards. This moves the toothed plate 33 inside the serrated blade 32 downwards, driving the cutting blade 34 at the bottom of the toothed plate 33 to quickly cut the larger area of ​​the container bag. The operator can then rotate the rotating handle 45, causing the threaded rod 43 to rotate. This moves the moving plate 42 on the threaded rod 43 outwards, moving the horizontal plate 41... The toothed plate 33 on the side moves out from the serrated blade 32, and then the drive cylinder 46 is activated. The drive cylinder 46 can drive the sliding block 44 to move along the slide groove, thereby moving the cutting flat blade 34 at the bottom of the toothed plate 33 upward, exposing the serrated blade 32. Then the hydraulic cylinder 8 is activated, which can make the connecting plate 31 move back and forth. Because one end of the electric telescopic rod 5 is fixedly connected to the slider 6, and the slider 6 is slidably connected in the groove in the connecting plate 31, the connecting plate 31 can move back and forth while driving the serrated blade 32 to cut thicker FIBCs. This method of changing the cutting blade is more time-saving and labor-saving, and the cutting efficiency is also higher.
