[0024] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0025] As Figure 1 - Figure 5 shown, a cutting device of a bag - making machine provided in this embodiment includes a device body 1. Inside the device body 1, there are support legs 2. The outer wall of the support legs 2 is connected to a placing table 4, and the upper ends of the support legs 2 are connected to an operating table 3. Above the placing table 4, there is a mounting seat 5. At the upper end of the mounting seat 5, there is a limiting ring 6. Inside the limiting ring 6, there is a spline sleeve 7. Inside the spline sleeve 7, there is a spline shaft 8 inserted. One end of the spline shaft 8 is connected to a rewinding rod 9 and a motor 12. A material 13 is sleeved on the rewinding rod 9. On the operating table 3, a cross frame 14 and a support frame 19 are sequentially installed. At the upper end of the cross frame 14, there is a fixed frame 16. On the fixed frame 16, there is a cylinder 17. Below the cylinder 17, there is a heat - able cutting knife 181 connected. Inside the support frame 19, there is an electric push rod 20. At the front end of the electric push rod 20, there is a clamping plate 21.

[0026] Preferably, both the spline sleeve 7 and the spline shaft 8 are provided with pin holes. Inside the pin holes of the spline sleeve 7 and the spline shaft 8, there is a pin rod 10 inserted. At the front and rear ends of the pin rod 10, there are nuts 11 screwed. By setting the pin rod 10, the spline sleeve 7 and the spline shaft 8 can be connected. By setting the nuts 11, the stability of the device is increased, ensuring the safety of the device during use. There are multiple groups of cross frames 14. Inside the multiple groups of cross frames 14, there are rollers 15 installed. By setting the rollers 15, the cut material 13 can be pulled, facilitating the user to move the position of the material 13, increasing the practicability and convenience of the device.

[0027] Preferably, a guide rod 18 is connected to the upper end of the heatable cutting knife 181. There are two sets of guide rods 18 arranged symmetrically. The guide rods 18 are slidably installed in the fixed frame 16. By providing the guide rods 18, the moving direction of the heatable cutting knife 181 can be guided, avoiding the situation of position deviation of the heatable cutting knife 181 during the moving process. There are multiple sets of clamping plates 21 arranged symmetrically. Anti-slip pads 22 are fixedly installed on the inner walls of the clamping plates 21. By providing the anti-slip pads 22, the anti-slip performance of the clamping plates 21 is increased, ensuring the safety and stability of the device during use. There are two sets of mounting seats 5 arranged symmetrically. The two sets of mounting seats 5 are screwed and fixed to the upper limiting ring 6, increasing the connection and intimacy between the devices, ensuring the safety of the device during use and facilitating subsequent disassembly and assembly.

[0028] The working principle and process of the present utility model: During use, the bag material 13 to be cut is sleeved on the winding rod 9, and then the spline shaft 8 of the winding rod 9 is inserted into the spline sleeve 7. After the insertion is completed, the pin rod 10 is inserted into them and fixed with a nut 11. The limiting ring 6 is installed on the spline sleeve 7, and then the limiting ring 6 is screwed to the mounting seat 5. (Conversely, the material 13 can be disassembled and re-fed). Control the motor 12 to drive the winding rod 9 to rotate. When the winding rod 9 rotates, the user pulls the material 13 at the other end. When pulling, control the cylinder 17 to operate, and the cylinder 17 drives the heatable cutting knife 181 to move downward. During the moving process, the bag material 13 to be cut is cut. The feeding of the bag material 13 to be cut can be processed according to the use needs, increasing the practicability and convenience of the device, avoiding the situation that the material 13 is inconvenient to feed and affecting the subsequent cutting efficiency. When the device needs to be guided during the feeding and cutting process, control the electric push rod 20 to operate, and the electric push rod 20 drives the clamping plate 21 to push forward. The clamping plate 21 approaches the material 13 until the clamping plate 21 and the anti-slip pad 22 are adjusted to a suitable distance, ensuring that the material 13 can pass through the adjusted distance. The user pulls the material 13, and the material 13 slides on the roller 15 when pulled. When sliding to a suitable distance, the material 13 can be cut. The material 13 to be cut can be guided and limited, ensuring the safety of the material 13 during cutting, improving the cutting quality of the device, and avoiding the situation of material 13 waste caused by incorrect cutting.
