[0054] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0055] Example 1
[0056] As shown in Figure 1, this embodiment discloses a film supply device for a bag making and sealing machine, which is used to reduce the probability of defective products. It mainly includes a power supply device 1, a frame 2, a guide roller 3, a traction mechanism 4, and a film feeding component 5. In use, the operator first places the film material ring 8 onto the outer wall of the guide roller shaft 3, with the inner diameter of the film material ring 8 approximately equal to the outer diameter of the guide roller shaft 3. Then, the leading end of the film material 9 on the film material ring 8 is guided to the traction mechanism 4 using a film material guide (not shown in the figure). Normally, the power supply device 1 is electrically connected to a control device (not shown in the figure). The operator presses the corresponding button in the control device to start the power supply device 1, and the traction mechanism 4 begins to pull the film material 9 toward the film feeding component 5. The guide roller shaft 3 rotates clockwise, and the guide roller shaft 3 moves synchronously with the film material ring 8. This is existing technology, and the relevant details will not be elaborated. Next, the operator uses the film material guide to guide the leading end of the film material 9 past the film feeding component 5. After a period of time, the leading end of the film material 9 is guided to the receiving end of the printing mechanism 6, and the corresponding printing operation is completed. The output end of the printing mechanism 6 sequentially delivers the first end of the film material 9 to the peripheral heat sealing process and subsequent processes. At this time, the operator no longer needs to guide the film material 9 with the film material guide, because in this embodiment, the film material 9 on the film material ring 8 can be automatically transferred to the printing mechanism 6. This design reduces the workload of the operator and improves work efficiency. When the operator finds that the tail end of the old film material has moved to the film feeding component 5, he first presses the corresponding button on the control device to stop the film guide roller 3 from working. Then, he inserts the new film material ring into the film guide roller 3. Then, he presses the corresponding button on the control device to start the film guide roller 3 from working. At the same time, the film material guide guides the first end of the new film material through the traction mechanism 4 and the film feeding component 5, following the tail end of the old film material, to the receiving end of the printing mechanism 6. This design easily achieves the purpose of changing the film material ring 8 without stopping the machine.

Compared with the prior art, this utility model improves the quality of the bag and reduces the probability of defective products to a certain extent, thus having high practicality.
[0058] In a specific application scenario, the traction mechanism 4 mainly includes an installation platform 41, a membrane material traction machine 42, a membrane entry component 43, and a membrane exit component 44. The left side of the installation platform 41 is connected to the right side of the frame 2. The membrane material traction machine 42 is located along the length of the top of the installation platform 41. The membrane entry component 43 is located near its end on the right side of the frame 2, between the installation platform 41 and the guide roller 3. The membrane exit component 44 is located on the right side of the frame 2, between the installation platform 41 and the film delivery component 5. In use, the membrane material 9 enters the membrane material traction machine 42 via the membrane entry component 43. Then, the membrane material 9 moves from the output end of the membrane material traction machine 42 to the membrane exit component 44, which guides the membrane material 9 to the film delivery component 5. This is existing technology, and the relevant details will not be elaborated here.
[0059] Furthermore, the film feeding component 43 mainly includes a first rotating assembly 431 and a film feeding roller 432; specifically, the first rotating assembly 431 is generally composed of a first driving block (not marked in the figure) and a first rotating shaft (not marked in the figure). The left side of the first driving block is connected to the right side of the frame 2, and the first driving block is electrically connected to the power supply equipment 1. This is prior art, and the corresponding details will not be elaborated here; the driving end of the first driving block is provided with a first rotating shaft, which is arranged along the length direction of the mounting platform 41; the outer wall of the first rotating shaft is fitted with the film feeding roller 432.
[0060] Furthermore, the film exit component 44 mainly includes a second rotating assembly 441 and a film exit roller 442; specifically, the second rotating assembly 441 is generally composed of a second driving block (not marked in the figure) and a second rotating shaft (not marked in the figure). The bottom of the second driving block is connected to the top of the frame 2, and the second driving block is electrically connected to the power supply device 1. This is prior art, and the corresponding details will not be elaborated here; the driving end of the second driving block is provided with a second rotating shaft, which is arranged along the length direction of the mounting platform 41; the outer wall of the first rotating shaft is fitted with an infeed roller 432.
[0061] Furthermore, the connection surface between the mounting platform 41 and the membrane material traction machine 42 is an inclined plane, that is, the height of the side of the mounting platform 41 near the membrane entry component 43 is lower than the height of the side of the mounting platform 41 near the membrane exit component 44. This design can stably traction the membrane material 9 and further reduce the probability of defective products to a certain extent.
[0062] In a specific application scenario, the film feeding component 5 mainly includes a film feeding shaft 51 and a film feeding cylinder 52. There are several film feeding shafts 51, and the left and right ends of the film feeding shafts 51 are rotatably connected to the left and right sides of the frame 2, respectively.

Several film feeding cylinders 52 are arranged below the film feeding shafts 51, and the left end of the film feeding cylinders 52 is connected to the left side of the frame 2. The difference between the number of film feeding shafts 51 and the number of film feeding cylinders 52 is 1. This design can improve the effect of the printing mechanism 6 pulling the film material 9 from the film feeding component 5.
[0063] Furthermore, the number of film feeding shafts 51 is greater than the number of film feeding cylinders 52. This design can further improve the effect of the printing mechanism 6 pulling the film material 9 from the film feeding component 5.
[0064] In a specific application scenario, the printing mechanism 6 mainly includes a platform 61 and a printer 62. The platform 61 is L-shaped, with its left side connected to the right side of the power supply device 1 and its bottom end in contact with the ground. The printer 62 is located at the top of the platform 61 and is electrically connected to the power supply device 1. In use, the film material 9 on the film feeding component 5 is pulled to the printer 62. After the printer 62 completes the printing operation on the film material 9, it can be conveyed to subsequent equipment.
[0065] This embodiment takes into account a situation, and the specific solution is as follows: When the speed of the printing mechanism 6 and the subsequent equipment in processing the film material 9 decreases, the control device can send a control command to the power supply device 1. The power supply device 1 will reduce its power supply to the guide roller 3, the traction mechanism 4, the film feeding component 5 and the printing mechanism 6, thereby making the speed of processing the film material 9 in this embodiment match the speed of processing the film material 9 in the subsequent equipment, thereby reducing the probability of defective products to a certain extent.
