Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, and in particular to a material correction device for a bag making machine. Background Technology

[0002] A bag-making machine is a machine that produces various plastic or other material packaging bags. Its processing range includes packaging bags of various sizes, thicknesses, and specifications made of plastic or other materials. Generally, plastic packaging bags are the main product. During the use of the bag-making machine, in order to prevent the packaging bags from deviating or shifting during the conveying process, it is usually necessary to use a straightening machine to adjust the position of the packaging bags. The straightening machine can ensure the accuracy of the packaging bag's position.

[0003] Traditional web guiding machines have poor compatibility and lack height adjustment function, making it difficult to match the height of packaging bags on the conveyor line of different models of bag making machines, which limits the reusability of the equipment. In addition, the two round rollers on the web guiding machine used to adapt to packaging bags of different widths need to be manually adjusted one by one, which is cumbersome to operate.

The two vertical blocks 19 are both fixedly installed on one side of the adjusting plate 18, the connecting rod 20 is fixedly installed between the two vertical blocks 19, and the circular roller 21 is rotatably mounted on... On the second connecting rod 20, two welding blocks 28 are fixedly installed on both sides of the adjusting plate 18, and an arc-shaped rod 29 is fixedly installed between the two welding blocks 28. The connecting block 22 is slidably installed on the arc-shaped rod 29. The connecting block 22 is rotatably connected to the top end of the corresponding hinge rod 10. A connecting block 23 is fixedly installed on one side of the mounting plate 12. A rotating block 24 is rotatably installed on the connecting block 23. A side block 25 is fixedly installed on one side of the mounting frame 6. A circular rotating rod 26 is rotatably installed on the side block 25. An electric push rod 27 is fixedly installed at the top end of the circular rotating rod 26. The output rod of the electric push rod 27 is fixedly connected to one side of the rotating block 24.

[0025] To increase the stability of the mounting bracket 6 and make the connection between the support frame 1 and the mounting bracket 6 more secure, in this method, the support frame 1 is provided with four vertical holes, and U-shaped blocks are fixedly installed on both sides of the mounting bracket 6, with two U-shaped blocks slidingly installed in the four vertical holes respectively.

[0026] In order to provide sufficient room for movement of the two hinge rods 10 and to avoid restricting their movement, in this method, the mounting bracket 6 has two transverse holes, and the two hinge rods 10 are respectively rotatably installed in the two transverse holes.

[0030] The working principle of the material correction device for the bag making machine provided by this utility model is as follows:

[0031] During the use of the bag making machine, the bottom of the packaging bag contacts the first roller 15, and the sides contact the two second rollers 21. When the position of the packaging bag is offset and needs to be adjusted, the electric push rod 27 can be activated. The output rod of the electric push rod 27 will gradually extend outward or retract inward, thereby driving the mounting plate 12 to rotate around the positioning block 11 as the center. The mounting plate 12 then drives the two second rollers 21, and the two connecting blocks 22 will slide on the two arc rods 29. The first roller 15 and the two second rollers 21 rotate simultaneously. During the rotation, the first roller 15 and the two second rollers 21 will correct the position of the packaging bag left and right.

[0032] When a wider packaging bag needs to be accommodated, rotate the double-headed screw 8. The two sliding blocks 9 will move simultaneously on the double-headed screw 8, gradually increasing the distance between them. Driven by the two sliding blocks 9, the two adjusting plates 18 will gradually rotate around the two U-shaped rods 16. The raised bottom ends of the two adjusting plates 18 will gradually move down, thereby lowering the position of the two circular rollers 21 and increasing the distance between them. This allows the two circular rollers 21 to accommodate a wider packaging bag. Conversely, when a narrower packaging bag needs to be accommodated, simply rotate the double-headed screw 8 in the opposite direction.

[0033] When the correction device needs to be applied to different bag making machines, the height of the first roller 15 and the two second rollers 21 can be adjusted so that the correction device can be used for different bag making machines. During operation, the double-headed screw 2 is rotated and the two moving blocks 3 slide simultaneously. Through the cooperation of the two hinge rods 4, the mounting frame 6 is driven to slide, and the height of the mounting frame 6 is adjusted so that the height of the first roller 15 and the two second rollers 21 can be adapted to the packaging bags on the bag making machine, thereby improving the applicability of the correction device.

[0034] Compared with related technologies, the material correction device for the bag making machine provided by this utility model has the following beneficial effects:

[0035] In this invention, the height of the mounting frame 6 can be quickly adjusted by manually rotating the double-headed screw 2, so that the first roller 15 and the two second rollers 21 can adapt to the height of the packaging bags on the bag making machine of different heights, thus improving the applicability of the equipment. Manually rotating the double-headed screw 8 can adjust the position of the two second rollers 21 at one time, improving the convenience of adjustment and ensuring that the adjustment range of the two second rollers 21 is consistent. The start of the electric push rod 27 can adjust the angle of the position of the first roller 15 and the two second rollers 21, thereby adjusting the angle of the packaging bag to achieve position correction.
