The outside of the metal heating ring 14 is rotatably connected to a metal roller 15 through a bearing. A pulley 16 is provided at the front end of the rotating shaft 9, and the pulleys 16 are connected by a belt 17. A motor 18 is provided on the rear side of the flattening shell 1, and the input end of the motor 18 is electrically connected to the output end of the single-chip computer 2. The output shaft of the motor 18 is fixedly connected to the rear end of the rotating shaft 9 on the left side. A telescopic column 4 and a spring 5 are provided between the slide seat 6 and the adjacent slide groove. The spring 5 is movably sleeved with the outer end of the adjacent telescopic column 4. Between the front and rear walls of the flattening shell 1 Auxiliary rollers 12 are evenly distributed and connected through bearing rotation. Auxiliary rollers 12 are respectively installed with feed roller 11, rotating roller 81 and metal roller 15. Spring 15 is in a compressed state. When flattening the container bag, first, single chip computer 2 starts conveyor 3, and uses belt contact friction to flatten and convey the container bag from left to right. After the container bag enters the flattening shell 1, single chip computer 2 starts motor 18 so that its output shaft drives the left end shaft 19 to rotate forward. Shaft 19 drives the right side shaft 19 to rotate synchronously through the belt transmission between pulley 16 and belt 17. The two pulleys 16 have different calibers, so as to avoid affecting the belt transmission. Shaft 19 drives the corresponding feed roller 11 and the rotating roller 81 rotate synchronously. The lower feeding roller 11 cooperates with the upper feeding roller 11 during rotation, and uses the contact friction to transport the container bag to the right. The upper feeding roller 11 and the rotating roller 81 perform vertical squeezing and flattening operations on the container bag through the compression elastic force of the spring 15. After the container bag is flattened, it continues to move to the right. The single-chip microcomputer 2 starts the metal heating ring 14 to heat the metal roller 15. The metal roller 15 heats the flattened container bag to flatten and shape it. The auxiliary roller 12 is used to reduce the contact gap between the rotating roller 81 and the feeding roller 11 and the metal roller 15 to avoid vertical deviation during the container bag's rightward movement and flattening process.

[0028] Container bag horizontal pulling limit mechanism 7: It is respectively arranged on the upper and lower walls of the flattening shell 1. The container bag horizontal pulling limit mechanism 7 includes an electric push rod 71, a vertical moving frame 72, a telescopic column 73, a spring 74 and a vertical pressure roller 75. The electric push rod 71 is respectively arranged on the upper and lower walls of the flattening shell 1. The input end of the electric push rod 71 is electrically connected to the output end of the single-chip computer 2. The telescopic end of the electric push rod 71 is provided with a vertical moving frame 72. The front and rear ends of the vertical moving frame 72 are provided with a vertical pressure roller 75 through the telescopic column 73 and the spring 74. The spring 74 is movably connected to the outer end of the adjacent telescopic column 73. After the container bag enters the flattening shell 1, the single-chip computer 2 starts the two electric push rods 71 ​​to extend their telescopic ends, indirectly driving the vertical pressure roller 75 to move vertically The upper and lower sides of the container bag are squeezed. As the telescopic end of the electric push rod 71 continues to extend, the telescopic end of the telescopic column 2 73 and the spring 2 74 contract. As the feeding roller 11 rotates and transports the container bag, the left end of the container bag in the device is slightly squeezed and fixed vertically by the compression force of the spring 2 74, so that when the container bag moves to the right, it is necessary to overcome the compression force of the spring 2 74, so that the container bag between the vertical pressing roller 75 and the feeding roller 11 is in a horizontal transverse stretching state, avoiding transverse wrinkles in the process of flattening the container bag. The container bag processing flattening machine can automatically flatten the transverse wrinkles on the surface of the container bag through the transmission element during the process of flattening the container bag, effectively improving the flattening effect of the device on the container bag;

[0029] Longitudinal leveling mechanism 8: It is respectively arranged on the outer side of the rotating shaft 1 9 and the rotating shaft 2 10 on the right side. The longitudinal leveling mechanism 8 includes a rotating roller 81, a spiral rubber sheet 82, a guide groove 83, a fixing ring 84, a telescopic column three 85 and a spring three 86. The rotating roller 81 is evenly slidably connected to the outer side of the rotating shaft 1 9 and the rotating shaft 2 10 on the right side. The outer side of the rotating roller 81 is provided with a spiral rubber sheet 82. The spiral directions of the two longitudinally adjacent spiral rubber sheets 82 are opposite. The outer side of the rotating shaft 1 9 and the rotating shaft 2 10 on the right side are provided with a guide groove 83. The rotating roller 81 is slidably connected to the adjacent guide groove 83. The outer side of the rotating shaft 1 9 and the rotating shaft 2 10 on the right side is provided with evenly distributed fixing rings 84. Evenly distributed telescopic columns three 85 and springs three 86 are provided between the fixing ring 84 and the adjacent rotating roller 81. The springs three 86 are connected to the adjacent telescopic columns 85 and springs three 86. The outer end of the contraction column three 85 is movably sleeved. During the container bag flattening process, as the container bag continues to move right, the rotating roller 81 contacts it. The spiral directions of the two longitudinally adjacent spiral rubber sheets 82 are opposite. The rotating roller 81 drives the spiral rubber sheet 82 to rotate. The spiral rubber sheet 82 uses the contact friction force through the spiral direction to apply a longitudinal forward or backward horizontal friction pulling force to the container bag, thereby longitudinally flattening the pressing surface of the container bag, improving the flattening effect of the container bag, and being easy to use. During this process, the telescopic end of the telescopic column three 85 and the spring three 86 are adaptively contracted, thereby limiting the longitudinal sliding distance of the rotating roller 81 along the guide groove 83. During the container bag flattening process, the container bag processing flattening machine can automatically perform longitudinal wrinkle flattening on the surface of the container bag through the transmission element, effectively improving the flattening effect of the device on the container bag.

[0030] The working principle of a container bag processing and flattening machine provided by the utility model is as follows: when the spring 15 is in a compressed state and the container bag is flattened, the single chip computer 2 starts the conveyor 3 first, and the container bag is flattened and conveyed from left to right by using the contact friction of the belt. After the container bag enters the flattening shell 1, the single chip computer 2 starts the motor 18 so that its output shaft drives the rotating shaft 19 at the left end to rotate forwardly. The rotating shaft 19 drives the rotating shaft 19 on the right side to rotate synchronously through the belt transmission between the pulley 16 and the belt 17. The two pulleys 16 have different calibers, so as to avoid affecting the belt transmission. The rotating shaft 19 drives the corresponding feeding roller 11 and the rotating roller 81 to rotate synchronously. During the rotation of the lower feeding roller 11, the feeding roller 11 on the upper side cooperates with the feeding roller 11 on the upper side, and utilizes the contact friction force to transport the container bag to the right. The compression elastic force of the spring 15 makes the feeding roller 11 on the upper side and the rotating roller 81 perform vertical squeezing and flattening operations on the container bag. At the same time, after the container bag enters the flattening shell 1, the single-chip microcomputer 2 starts the two electric push rods 71 ​​to extend their telescopic ends, indirectly driving the vertical pressing roller 75 to move vertically and squeeze the upper and lower sides of the container bag. As the telescopic end of the electric push rod 71 continues to extend, the telescopic end of the telescopic column 2 73 and the spring 2 74 contract. As the feeding roller 11 rotates and transports the container bag, the spring 2 74 is used to press the container bag. The compression force of spring 74 is used to slightly squeeze and fix the left end of the container bag in the device vertically, so that when the container bag moves to the right, it needs to overcome the compression force of spring 2 74, so that the container bag between the vertical pressing roller 75 and the feeding roller 11 is in a horizontal transverse stretching state, avoiding transverse wrinkles in the process of flattening the container bag. As the container bag continues to move to the right, the rotating roller 81 contacts it, and the spiral directions of the two longitudinally adjacent spiral rubber sheets 82 are opposite. The rotating roller 81 drives the spiral rubber sheet 82 to rotate, and the spiral rubber sheet 82 uses the contact friction force through the spiral direction to apply a longitudinal forward or backward horizontal friction pulling force to the container bag, thereby The flattening surface of the container bag is longitudinally flattened to improve the flattening effect of the container bag, and it is easy to use. During this process, the telescopic end of the telescopic column three 85 and the spring three 86 are adaptively contracted, thereby limiting the longitudinal sliding distance of the rotating roller 81 along the guide groove 83. After the container bag is flattened, it continues to move right. The single-chip microcomputer 2 starts the metal heating ring 14 to heat the metal roller 15. The metal roller 15 heats the flattened container bag to flatten and shape it. The auxiliary roller 12 is used to reduce the contact gap between the rotating roller 81 and the feed roller 11 and the metal roller 15, thereby avoiding vertical deviation during the rightward movement and flattening of the container bag.

The single chip microcomputer 2 controls the conveyor 3, the electric push rod 71, the metal heating ring 14 and the motor 18, all of which adopt the methods commonly used in the prior art.
