[0020] This utility model provides a tension frame for a bag-making machine, including a fixed frame 101 and a processing mechanism 102. The processing mechanism 102 includes a heating box 103, a heating plate 104, multiple heat dissipation teeth 105, a movable adjustment component 106, a positioning adjustment component 107, and a bag-exit component 108.

[0021] In this specific embodiment, the bag-dispensing assembly 108 is fixedly connected to the fixed frame 101, the positioning adjustment assembly 107 is slidably connected to the fixed frame 101, the movable adjustment assembly 106 is slidably connected to the fixed frame 101, each heat dissipation tooth 105 is fixedly connected to the heating plate 104, the heating plate 104 is fixedly connected to the heating box 103, the heating box 103 is fixedly connected to the fixed frame 101, and both ends of each first roller 112 are respectively connected to the corresponding electric telescopic rod 113.

The other end of the first air rod 110 is fixedly connected to the output end of the first cylinder 109. The first cylinder 109 is fixedly connected to the fixing frame 101. Both ends of each of the second rollers 117 are rotatably connected to the corresponding positioning rod 118. The lower end of each positioning rod 118 is fixedly connected to the second mounting plate 116. One side of the second mounting plate 116 is fixedly connected to the second air rod 115, and the other end of the second air rod 115 is fixedly connected to the output end of the second cylinder 114. The second cylinder 114 is fixedly connected to the fixing frame 101. Each bag-discharging roller 121 is rotatably connected to the bag-discharging frame 120. The bag-discharging frame 120 is fixedly connected to each spring telescopic rod 119. The upper end of each spring telescopic rod 119 is fixedly connected to the fixing frame 101. Both foot frames 124 are fixedly connected to the protective shell 122. The flap 123 is fixedly connected to the protective shell 122. The first mounting plate 111 in the movable adjustment component 106 and the second mounting plate 116 in the positioning adjustment component 107 move laterally and work together with multiple electric telescopic rods 113 to adjust the tension of the bag to be processed more accurately. This design is simple in structure and easy to produce. It solves the problem that the tension adjustment of the bag can only be adjusted by the extension and retraction of the electric telescopic rods 113, which has limited tension control effect and low accuracy.
[0022] The bag-dispensing assembly 108 is located on the inner top wall of the fixed frame 101, the positioning adjustment assembly 107 is located below the fixed frame 101, the movable adjustment assembly 106 is located above the fixed frame 101, each heat dissipation tooth 105 is located above the heating plate 104, the heating plate 104 is located above the heating box 103, and the heating box 103 is located inside the fixed frame 101. Connecting blocks are provided at the connection between the first mounting plate 111 and the first air rod 110 and at the connection between the second mounting plate 116 and the second air rod 115. Driven by the corresponding cylinders, the relative positions of the first mounting plate 111 and the second mounting plate 116 are changed, thereby adjusting the tension change of the processed bag in the lateral direction. At the same time, the tension change in the vertical direction is achieved in conjunction with the multiple electric telescopic rods 113.
[0023] Secondly, the two ends of each first roller 112 are respectively located at the lower ends of the corresponding electric telescopic rod 113, and the upper ends of each electric telescopic rod 113 are located below the first mounting plate 111. One side of the first mounting plate 111 is located at one end of the first air rod 110, and the first air cylinder 109 is located above the fixing frame 101. The two ends of each second roller 117 are respectively located at the upper ends of the corresponding positioning rod 118, and the lower ends of each positioning rod 118 are located above the second mounting plate 116. One side of the second mounting plate 116 is located at one end of the second air rod 115. The cylinder 114 is located below the fixed frame 101. After the processing bag is fully wrapped, the operator adjusts the length of each electric telescopic rod 113 according to the production and processing requirements, and at the same time adjusts the relative position of the first mounting plate 111 and the second mounting plate 116 to change the tension on the processing bag. Both the lateral and longitudinal tension can be adjusted, resulting in better processing effect. Before the processing bag is moved, the heating box 103 needs to be started to raise the temperature of the heating plate 104. At the same time, a temperature sensor is also provided on the inner side of the heating plate 104 so that the operator can know the specific temperature changes and control it, making the quality control of the material more precise.
[0024] Meanwhile, each of the bag-discharging rollers 121 is located below the bag-discharging frame 120, which is located at the lower end of each of the spring telescopic rods 119. The upper end of each of the spring telescopic rods 119 is located on the inner top wall of the fixing frame 101. The two foot frames 124 are located on both sides of the protective shell 122. The flip plate 123 is located on one side of the protective shell 122. The flip plate 123 is designed to facilitate manual placement of the processing bag by the operator to wind it between the first roller 112 and the second roller 117. The processing bag needs to enter the protective shell 122 from the first roller 112 and wind around the second roller 117 and the other first roller 112 in sequence. Finally, the processing bag slides out of the protective shell 122 above each of the bag-discharging rollers 121.
[0025] In this embodiment, connecting blocks are provided at the connection points of the first mounting plate 111 and the first air rod 110, and at the connection points of the second mounting plate 116 and the second air rod 115. Driven by the corresponding cylinders, the relative positions of the first mounting plate 111 and the second mounting plate 116 are changed, thereby adjusting the tension on the processing bag in the lateral direction. Simultaneously, multiple electric telescopic rods 113 are used to achieve tension changes in the vertical direction. After the processing bag is fully wound, the operator adjusts the length of each electric telescopic rod 113 according to production needs, and simultaneously adjusts the relative positions of the first mounting plate 111 and the second mounting plate 116 to change the tension on the processing bag, altering the lateral and longitudinal tension. All of these can be adjusted, resulting in better processing effects. Before moving the processing bag, the heating box 103 needs to be activated to raise the temperature of the heating plate 104. At the same time, a temperature sensor is also provided on the inner side of the heating plate 104 so that the staff can know the specific temperature changes and control them, making the quality control of the material more precise. The flip plate 123 is designed to facilitate the staff to manually place the processing bag and wrap it between the first roller 112 and the second roller 117. The processing bag needs to enter the protective shell 122 from the first roller 112 and then wrap around the second roller 117 and the other first roller 112 in sequence. Finally, the processing bag slides out of the protective shell 122 above each bag exit roller 121.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
