Description

Technical Field

[0001] This utility model relates to the field of container bag processing, specifically a container bag inner membrane cutting machine. Background Technology

[0002] This utility model belongs to the field of FIBC production and processing equipment. It is designed for the cutting needs of the sheet-like reinforcing inner film (polyethylene / polypropylene material, to ensure bag strength and leak prevention), a key component of FIBCs. Currently, the industry mainly uses traditional semi-automatic cutting equipment or general cutting beds, which complete the processing by manually laying the film, feeding with conveyor rollers, and cutting with fixed blades. It is suitable for FIBC production lines in the chemical, building materials and other fields, but it is difficult to meet the current requirements for precision and efficiency. Traditional cutting equipment suffers from three major problems: poor guiding and limiting; reliance on fixed-size side baffles, making it unsuitable for the dynamic conveying of flexible inner films of different widths, leading to deviation and curling; low stability and ease of pressing down on the workpiece during cutting, easily causing deformation or crushing; and the fact that current equipment blades typically cut from top to bottom, easily causing workpiece deformation under pressure, affecting the accuracy and practicality of workpiece cutting, and also easily causing incomplete cutting or equipment damage due to errors. Therefore, it is necessary to design a container bag inner film cutting machine to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a machine for cutting the inner membrane of a container bag to solve the problems mentioned in the background art.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please refer to Figure 1-6 As shown, this utility model provides a container bag inner film cutting machine, including a frame 1 of the cutting machine, a conveyor belt 2 installed on the inner side of the frame 1, a fixed frame 3 fixedly installed on the top of the frame 1, and mounting frames 4 respectively installed on the top of the frame 1 and on both sides of the fixed frame 3. A driving component for driving the cutting part to move is installed on the top of the fixed frame 3, a pressing component for fixing the workpiece is installed on the inner side of the mounting frame 4, and guide components for limiting the workpiece are respectively installed on both sides of the mounting frame 4.

[0017] It should be added that both the fixing frame 3 and the mounting frame 4 have U-shaped cross sections. The pressing component on the inner side of the mounting frame 4 can press down and fix the workpiece to prevent it from shifting or shaking. The guide components on both sides of the fixing frame 3 can limit and guide the edge of the workpiece so that the two guide components can limit and guide workpieces of different widths to avoid the workpiece shifting during the conveying process. The driving component can drive the cutting component to move longitudinally to cut, improving the accuracy and practicality of the cutting component in cutting the workpiece.

[0018] Specifically, the driving component includes a groove 6 formed on the top of the fixed frame 3 to provide a sliding path for the slider 5. A first cylinder 7 is installed at one end of the fixed frame 3. A first push rod 8 is fixedly installed on one side of the slider 5 from one end of the first cylinder 7. A second cylinder 9 is installed on the top of the slider 5. A second push rod 10 extends from the bottom of the second cylinder 9. A movable frame 11 is bolted to the bottom of the second push rod 10. A guide rod 23 is installed on the top of the movable frame 11. The guide rod 23 passes through the slider 5 and is slidably connected to it.

[0019] The slide groove 6 has a cross-section in the shape of a cross. The slide groove 6 can guide the slider 5 and increase the contact area of ​​the slide groove 6 to support the slider 5 upward. The first cylinder 7 can drive the slider 5 to slide in the slide groove 6 through the first push rod 8. The second cylinder 9 at the top of the slider 5 can drive the moving frame 11 to move up and down through the second push rod 10. The guide rod 23 can limit the moving frame 11, reduce the longitudinal thrust on the second push rod 10, prevent the moving frame 11 from shaking when it drives the cutting part to cut the workpiece, and improve the convenience of the moving frame 11 in changing height and moving longitudinally.

[0020] More specifically, the cutting component includes a first cutter 12 fixed to the bottom of the movable frame 11 by bolts, a first electric telescopic rod 13 installed on the top of the movable frame 11, and a second cutter 14 fixed to the bottom of the first electric telescopic rod 13 by bolts. The first cutter 12 and the second cutter 14 slide in a staggered fit.

[0021] It should be added that both the first cutter 12 and the second cutter 14 are triangular, and the first cutter 12 and the second cutter 14 are staggered and fitted together. The first electric telescopic rod 13 can drive the second cutter 14 to slide up and down along the first cutter 12. The angle between the first cutter 12 and the second cutter 14 can quickly cut the workpiece.

[0022] Furthermore, the fixing components include a third cylinder 15 installed on the top of the mounting frame 4, a third push rod 17 extending from the bottom of the third cylinder 15 to fix the sliding plate 16, and an anti-slip strip 18 penetrating the bottom of the sliding plate 16. The guide components include second electric telescopic rods 19 respectively installed on both sides of the mounting frame 4, a sliding frame 20 welded to one end of the second electric telescopic rod 19, a limit wheel 22 installed on the inner side of the sliding frame 20 through a fixed shaft 21, and limit rods 24 fixedly installed on the top of the sliding plate 16 and near both ends, the limit rods 24 penetrating the mounting frame 4 and slidingly connected to it.

[0023] The third cylinder 15 can drive the sliding plate 16 to move up and down through the third push rod 17. The two limit rods 24 can guide the sliding plate 16. The top of the sliding plate 16 is fixed to the anti-slip strip 18 by bolts. The anti-slip strip 18 is made of silicone and can protect the workpiece from slipping and deformation. The second electric telescopic rod 19 can drive the sliding frame 20 to move longitudinally, so that the sliding frame 20 drives the limit wheel 22 through the fixed shaft 21 to limit and guide the workpieces of different widths, preventing the workpieces from deviating or shaking during the conveying process.

[0024] Working principle: First, the workpiece is placed on the conveyor belt 2 at the top of the frame 1, and the conveyor belt 2 transports the workpiece. At the same time, the second electric telescopic rod 19 drives the sliding frame 20 to move longitudinally. Then, the sliding frame 20 drives the limiting wheel 22 through the fixed shaft 21 to limit and guide the workpiece. When cutting is required, the third cylinder 15 drives the sliding plate 16 to move downward through the third push rod 17. Then, the anti-slip strip 18 at the bottom of the sliding plate 16 presses down to fix and protect the workpiece. Then, the second cylinder 9 drives the moving frame 11 to move downward through the second push rod 10. The guide rod 23 limits the moving frame 11. The first cutter 12 at the bottom of the moving frame 11 pushes the edge of the workpiece and lifts it into the angle between the first cutter 12 and the second cutter 14. Then, the first cylinder 7 drives the slider 5 to slide in the slide groove 6 through the first push rod 8. Then, the slider 5 drives the first cutter 12 and the second cutter 14 in the moving frame 11 to cut the workpiece.
