Detailed Implementation

[0024] 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.

[0025] Example 1: Please refer to Figures 1-5 An automated paper bag machine includes a machine body 1, which is a fully automatic machine. Internally, it includes components such as a door, a placement plate, a blower, and an air duct. The placement plate has support rollers and conveyor rollers on its surface. Paper bags pass between the support rollers and a cutting blade roller 51, allowing the cutting blade 51 to press and cut the paper bag against the support rollers. A rubber sleeve is provided on the surface of the support rollers to prevent contact between the cutting blade 51 and the support roller surface. One end of the machine body 1 has a feed inlet 11 and a fixing plate 12. A guide roller 13 is rotatably connected to the side of the fixing plate 12. A servo motor 14 is located at the top of the machine body 1. The output end of the servo motor 14 has a lead screw, which is threadedly connected to a lifting mechanism. A pressure roller assembly is located at the bottom of the lifting mechanism to ensure the tension of the paper bag. This is existing technology. The paper bag machine body 1 is internally equipped with a cutting mechanism 2. The cutting mechanism 2 includes a positioning seat 3, a pulley 4, a cutting roller 5, and a mounting shaft 6. A bearing seat 34 is provided on one side of the positioning seat 3. A connecting shaft 32 is rotatably connected to one side of the bearing seat 34. A limiting plate 33 is fixedly sleeved on the surface of the connecting shaft 32. One end of the cutting roller 5 contacts and presses against the surface of the limiting plate 33. The limiting plate 33 is used to limit the installation position of one end of the cutting roller 5 and has a limiting function. The pulley 4 is fixedly sleeved on the surface of the connecting shaft 32. One end of the connecting shaft 32 is fixedly connected to one end of the mounting shaft 6. One end of the cutting roller 5 is provided with an axially penetrating mounting hole 52. The inner wall of the mounting hole 52 is slidably connected to the surface of the mounting shaft 6. A cutting blade 51 is provided on the surface of the cutting roller 5.

[0026] The surface of the positioning seat 3 is provided with positioning holes 31, and the inner wall of the positioning holes 31 is fitted with fastening bolts. The side of the paper bag machine body 1 is provided with annularly distributed bolt holes. The inner wall of the bolt holes is slidably connected to the surface of the fastening bolts, so that the cutting mechanism 2 can be disassembled and assembled with the paper bag machine body 1, which is convenient for later overall maintenance and replacement. A through hole is provided at the center of the annularly distributed bolt holes. The inner diameter of the through hole is larger than the outer diameter of the pulley 4, so that the cutting mechanism 2 can be removed from the paper bag machine body 1 through the through hole. One end of the mounting shaft 6 is fixedly connected to a connecting rod 61. The surface of the connecting rod 61 is slidably connected to a pressing plate 63. One side of the pressing plate 63 contacts and presses the end face of the cutting roller 5. The pressing plate 63 can restrict the position of one end of the cutting roller 5.

[0027] The surface of the connecting rod 61 is connected to a fastening nut 62 by a thread. The surface of the fastening nut 62 contacts and presses against the surface of the extrusion plate 63. The center of the extrusion plate 63 has a hole. The fastening nut 62 facilitates fixing the position of the extrusion plate 63 and makes it easy to disassemble and replace the cutting roller 5. The pulley 4 and the connecting shaft 32 are coaxial and concentric. The surface of the pulley 4 is provided with a belt groove 41. The inner wall of the belt groove 41 is fitted with a drive belt, which facilitates the paper bag conveying mechanism to drive the cutting roller 5 to rotate during the conveying process.

[0028] During operation, the automated paper bag machine's conveying mechanism drives the pulley 4 to rotate, which in turn drives the connecting shaft 32 to rotate. The connecting shaft 32 then drives the cutting roller 5 to rotate, which in turn conveys the paper bags and simultaneously rotates the support roller, thus positioning the paper bags. When the cutting roller 5 completes one revolution, it reaches the cut length of the paper bag. At this point, the cutting blade 51 rotates to its contact surface with the paper bag, pressing against the support roller to cut the bag, completing the cutting action. To replace the cutting roller 5, the machine door can be opened, and the fastening nut 62 can be turned counterclockwise using a wrench. To disassemble, ensure the mounting shaft 6 does not rotate when rotating the fastening nut 62. Then, disassemble the extrusion plate 63 and remove the cutting roller 5 from one end of the mounting shaft 6 for replacement. The cutting roller 5 and cutting blade 51 are designed to not only position the paper bag during transport but also prevent the transport from stopping when cutting the paper bag, greatly improving the working efficiency of the paper bag machine. Furthermore, the mounting shaft 6, connecting rod 61, fastening nut 62, and extrusion plate 63 not only ensure the rotational stability of the cutting blade 51 but also allow for the replacement of cutting rollers 5 with different outer diameters according to different cutting lengths of paper bags, facilitating later maintenance.
