Description

Technical Field

[0001] This utility model relates to the field of bag making machine cutting technology, and specifically discloses a cutting mechanism for an anti-deviation 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. In the working process of a bag-making machine, the cutting mechanism is an important component.

[0003] The cutting mechanism of existing bag making machines is prone to cutting position deviation when cutting roll materials. This is mainly because the roll material may be affected by various factors during the conveying process, such as poor flatness of the roll material itself, uneven rotation of the conveying rollers, and unstable tension. Once the cutting position deviates, the size of the produced bags will be off, which will seriously affect product quality, reduce production efficiency, and increase production costs. At the same time, after the roll material is cut, it is stacked in a messy manner and needs to be sorted out later, which increases the labor burden of workers. Utility Model Content

[0004] This utility model proposes a cutting mechanism for an anti-deviation bag making machine, which can level the roll material during the conveying process, avoid the problem of the cutting position shifting during the cutting process, prevent the impact on product quality, improve production efficiency, reduce production costs, and ensure that the cut roll material is stacked neatly.

[0023] Please see Figure 1-4 A cutting mechanism for an anti-deviation bag making machine includes a base 1, with two vertical plates 2 distributed front and back fixedly connected to the upper end face of the base 1, and a mounting platform 3 located between the two vertical plates 2 fixedly connected to the upper end face of the base 1. An anti-deviation mechanism and a cutting mechanism are provided between the two vertical plates 2.

[0024] The anti-deviation mechanism includes a first groove 4 formed on the upper surface of the mounting platform 3, and two first conveying rollers 5 rotatably connected between the two vertical plates 2.

[0025] In this embodiment: when using it, first roll the material as follows Figure 2 The roll material is laid out, and then the two first conveying rollers 5 rotate in opposite directions to convey the roll material. During the conveying process, because multiple leveling strips 7 are inclined towards the two ends of the lower first conveying roller 5, the rotating multiple leveling strips 7 can push the roll material towards the two ends of the lower first conveying roller 5, opening up both sides of the roll material and thus leveling it. At the same time, two limiting rings 6 limit both sides of the roll material. Through the cooperation between the multiple leveling strips 7 and the two limiting rings 6, the roll material is leveled during the conveying process, avoiding the problem of cutting position deviation during the cutting process, preventing the impact on product quality, improving production efficiency, and reducing production costs.

[0026] Then, during the conveying process of the roll material, the roll material is cut by the cooperation between the cutting mechanism and the mounting platform 3. The cut roll material falls onto the base 1 and is located on the right side of the mounting platform 3, so that the cut roll material is stacked neatly.

[0027] As a technical optimization of this utility model, the cutting mechanism includes a horizontal plate 8 fixedly connected to the upper end between two vertical plates 2, a cutting blade 9 is provided below the horizontal plate 8, an electric telescopic rod 10 is installed on the upper end surface of the horizontal plate 8, the output end of the electric telescopic rod 10 is fixedly connected to the cutting blade 9, and the left side wall of the cutting blade 9 is flush with the right side wall of the mounting platform 3.

[0028] In this embodiment: the electric telescopic rod 10 is activated, and the electric telescopic rod 10 drives the cutting blade 9 to move up and down. Since the left side wall of the cutting blade 9 is flush with the right side wall of the mounting platform 3, the roll material can be cut through the cooperation between the cutting blade 9 and the mounting platform 3.

[0029] As a technical optimization of this utility model, the upper end face of the mounting platform 3 is provided with a second groove 11 located to the left of the first groove 4, and two vertical plates 2 are rotatably connected to each other with two upper and lower distributed second conveying rollers 12, with the lower second conveying roller 12 located inside the second groove 11.

[0030] In this embodiment, the two second conveying rollers 12 rotate in opposite directions, and the roll material can be further conveyed through the two second conveying rollers 12.

[0031] As a technical optimization of this utility model, the rear ends of the two first conveying rollers 5 and the two second conveying rollers 12 extend to the rear side of the rear vertical plate 2 and are fixedly connected with meshing gears 13.

[0032] In this embodiment, multiple gears 13 can drive two first conveying rollers 5 and two second conveying rollers 12 to rotate in opposite directions.

[0033] As a technical optimization of this utility model, two drive motors 14 are installed on the front end face of the front vertical plate 2, and the output ends of the two drive motors 14 are fixedly connected to one of the first conveying rollers 5 and the second conveying roller 12 respectively.

[0034] In this embodiment, two drive motors 14 can drive one of the first conveying rollers 5 and the second conveying roller 12 to rotate.

[0035] As a technical optimization of this utility model, two slide rods 15 are fixedly connected to the upper end face of the cutting blade 9, and the upper ends of the two slide rods 15 extend to the top of the horizontal plate 8.

[0036] In this embodiment, the cutting blade 9 can be limited by two sliding rods 15, so that the cutting blade 9 can move smoothly.

[0037] As a technical optimization of this utility model, anti-slip pads are fixedly connected to the outer walls of the two first conveying rollers 5 and the two second conveying rollers 12.

[0038] In this embodiment, the anti-slip pad can increase the friction between the two first conveying rollers 5 and the two second conveying rollers 12 and the roll material, preventing the two first conveying rollers 5 and the two second conveying rollers 12 from sliding with the roll material.

[0039] Working principle and usage process of this utility model:

[0040] When using, first place the roll material as follows Figure 2The roll material is set up, and then one of the drive motors 14 is started. The drive motor 14 drives one of the first conveyor rollers 5. The first conveyor roller 5, in conjunction with two gears 13, drives the other first conveyor roller 5 to rotate in the opposite direction, thereby causing the two first conveyor rollers 5 to rotate in opposite directions. The roll material is conveyed by the two first conveyor rollers 5. During the conveying process, since multiple leveling strips 7 are inclined towards the two ends of the lower first conveyor roller 5, the rotating multiple leveling strips 7 can push the roll material towards the two ends of the lower first conveyor roller 5, opening up the two sides of the roll material and thus leveling the roll material. At the same time, the two limiting rings 6 limit the two sides of the roll material. Through the cooperation between the multiple leveling strips 7 and the two limiting rings 6, the roll material is leveled during the conveying process, avoiding the problem of cutting position deviation during the cutting process, preventing the impact on product quality, improving production efficiency, and reducing production costs.

[0041] Then, during the conveying of the roll material, the electric telescopic rod 10 is activated, which drives the cutting blade 9 to move up and down. Since the left side wall of the cutting blade 9 is flush with the right side wall of the mounting platform 3, the roll material can be cut through the cooperation between the cutting blade 9 and the mounting platform 3. The cut roll material falls onto the base 1 and is located on the right side of the mounting platform 3, thus making the cut roll material stacked neatly.
