Description

Technical Field

[0001] This utility model belongs to the field of container bag production technology, specifically relating to a cutting device for container bag production. Background Technology

[0002] FIBCs (Flexible Intermediate Bulk Containers) are packaging products used for transporting and storing bulk materials (such as fertilizers, cement, grains, and chemicals), and are typically made of durable textiles or synthetic materials. With the increasing demand for logistics and industrial packaging, FIBC production is gradually moving towards higher efficiency and automation. To meet this demand, cutting devices, as one of the key pieces of equipment in FIBC production, play a crucial role.

[0003] However, current FIBC (Flexible Intermediate Bulk Container) production technology has the following problems: Existing cutting devices on the market lack corresponding fixing mechanisms during cutting, causing the FIBC to easily shift and affecting product quality. Therefore, we propose a cutting device for FIBC production. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for producing FIBCs (Flexible Intermediate Bulk Containers), which can solve the problem in related technologies where there is no corresponding fixing device during cutting, and the FIBC is prone to shifting during cutting.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A cutting device for producing FIBCs (Flexible Intermediate Bulk Containers) includes a workbench, with a support leg fixedly connected to the bottom of the workbench and a fixing device provided on the top of the workbench.

[0007] The fixing device includes a support plate, which is fixedly connected to the front side of the workbench. A motor is fixedly connected to the back side of the support plate. A rotating rod is fixedly connected to the output shaft of the motor. A drive gear is fixedly connected to the circumferential surface of the rotating rod. A support bar is fixedly connected to the back side of the support plate. A rack is slidably connected to the side of the support bar.

[0008] A push rod is fixedly connected to the side of the rack, and a fixing strip is fixedly connected to the back side of the push rod. The function of the push rod is to drive the fixing strip to fix the container bag.

[0009] The number of the drive gear, rack, support rack, push rod, and fixing bar is set to two, and they are symmetrical to each other along the vertical central axis of the worktable. The circumferential surface of the drive gear and the side surface of the rack mesh with each other. The function of the drive gear is to drive the rack to move.

[0010] The top of the workbench is equipped with a cutting device, which includes a sprocket one. The inner wall of the sprocket one is fixedly connected to the circumferential surface of the rotating rod. A chain is provided on the circumferential surface of the sprocket one. A sprocket two is provided on the inner wall of the chain. A rotating rod is fixedly passed through the inner wall of the sprocket two. A support frame is fixedly connected to the side of the workbench. The circumferential surface of the rotating rod is rotatably connected to the support frame. A bevel gear one is fixedly connected to the circumferential surface of the rotating rod.

[0011] The bottom of the support frame is rotatably connected to a threaded rod, and a bevel gear is fixedly connected to the circumferential surface of the threaded rod. A threaded block is threadedly connected to the circumferential surface of the threaded rod, and a support column is fixedly connected to the bottom of the threaded block. A cutting device is fixedly connected to the bottom of the support column. The function of the threaded block is to drive the cutting device to cut the container bag.

[0012] A limiting rod is fixedly connected to the bottom of the support frame. The circumferential surface of the limiting rod slides through the inner wall of the threaded block. The function of the limiting rod is to restrict the displacement trajectory of the threaded block.

[0013] The circumferential surface of sprocket one meshes with the inner wall of the chain, the inner wall of the chain meshes with the circumferential surface of sprocket two, and the circumferential surface of bevel gear one meshes with the circumferential surface of bevel gear two.

[0025] like Figure 1-5 As shown, a cutting device for producing bulk bags includes a workbench 1, with a support leg 2 fixedly connected to the bottom of the workbench 1 and a fixing device 3 provided on the top of the workbench 1.

[0026] The fixing device 3 includes a support plate 31, which is fixedly connected to the front side of the workbench 1. A motor 32 is fixedly connected to the back side of the support plate 31. A rotating rod 33 is fixedly connected to the output shaft of the motor 32. A drive gear 34 is fixedly connected to the circumferential surface of the rotating rod 33. A support bar 35 is fixedly connected to the back side of the support plate 31. A rack 36 is slidably connected to the side of the support bar 35.

[0027] A push rod 37 is fixedly connected to the side of the rack 36, and a fixing strip 38 is fixedly connected to the back side of the push rod 37. The function of the push rod 37 is to drive the fixing strip 38 to fix the container bag.

[0028] The number of drive gear 34, rack 36, support bar 35, rack 36, push rod 37, and fixing bar 38 is set to two, and they are symmetrical to each other along the vertical central axis of the worktable 1. The circumferential surface of drive gear 34 meshes with the side surface of rack 36. The function of drive gear 34 is to drive rack 36 to move.

[0029] Based on the above structure, firstly, when it is necessary to cut the container bag, the fixing device 3 can be used to fix the container bag. By starting the motor 32, when the output of the motor 32 rotates, it will drive the rotating rod 33 to rotate. When the rotating rod 33 rotates, it will drive the drive gear 34 to rotate. When the drive gear 34 rotates, it will drive the rack 36 to move. When the rack 36 moves, it will drive the push rod 37 to move. Thus, when the push rod 37 moves, it will drive the fixing strip 38 to move downward, thereby achieving the effect of fixing the container bag.

[0030] like Figure 1-5 As shown, a cutting device 4 is provided on the top of the workbench 1. The cutting device 4 includes a sprocket 41, the inner wall of which is fixedly connected to the circumferential surface of the rotating rod 33. A chain 42 is provided on the circumferential surface of the sprocket 41, and a sprocket 43 is provided on the inner wall of the chain 42. A rotating rod 44 is fixedly passed through the inner wall of the sprocket 43. A support frame 45 is fixedly connected to the side of the workbench 1. The circumferential surface of the rotating rod 44 is rotatably connected to the support frame 45. A bevel gear 46 is fixedly connected to the circumferential surface of the rotating rod 44.

[0031] A threaded rod 47 is rotatably connected to the bottom of the support frame 45. A bevel gear 48 is fixedly connected to the circumferential surface of the threaded rod 47. A threaded block 49 is threadedly connected to the circumferential surface of the threaded rod 47. A support column 410 is fixedly connected to the bottom of the threaded block 49.

[0032] A limiting rod 412 is fixedly connected to the bottom of the support frame 45. The circumferential surface of the limiting rod 412 slides through the inner wall of the threaded block 49. The function of the limiting rod 412 is to limit the displacement trajectory of the threaded block 49.

[0033] The circumferential surface of sprocket 41 meshes with the inner wall of chain 42, the inner wall of chain 42 meshes with the circumferential surface of sprocket 43, and the circumferential surface of bevel gear 46 meshes with the circumferential surface of bevel gear 48. The function of sprocket 41 is to drive chain 42 and sprocket 43 to rotate.

[0034] According to the above structure, when the rotating rod 33 rotates, the cutting device 4 can be used to cut the container bag. When the rotating rod 33 rotates, it will drive the first sprocket 41 to rotate. When the first sprocket 41 rotates, it will drive the chain 42 to rotate. When the chain 42 rotates, it will drive the second sprocket 43 to rotate. When the second sprocket 43 rotates, it will drive the rotating rod 44 to rotate. When the rotating rod 44 rotates, it will drive the first bevel gear 46 to rotate. When the first bevel gear 46 rotates, it will drive the second bevel gear 48 to rotate. When the second bevel gear 48 rotates, it will drive the threaded rod 47 to rotate. When the threaded rod 47 rotates, it will drive the threaded block 49 to move. When the threaded block 49 moves, it will drive the cutting device 411 to move. Thus, when the cutting device 411 moves downward, the container bag will be cut.

[0035] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
