[0053] Example 2: Such as figure 2 with image 3 As shown, the smart coding system is fixed on the printing frame 23, wherein the width direction of the print head 24 is the same as the width direction of the bag-making film 17. The film conveying system is installed on the frame 16, wherein the film feeding device is installed in front of the print head 24 (take the direction of movement of the bag making film as a reference), and the film storage device is installed in front of the film feeding device. figure 2 Shown. The film feeding device includes a film drawing frame 26, a film pressing cylinder 27, an electric motor 21, and a linear drive 28. The film drawing frame 26 is fixed on the linear drive 28, the electric motor 21 is connected to the linear drive 28, and the film pressing cylinder 27 is installed on the film drawing frame. The rack 26 is on and above the bag film 17. When it starts to work, the film pulling frame 26 of the film feeding device is located at the right end, the film pressing cylinder 27 presses the bagging film 17 downwards, and the electric motor 21 drives the film pulling frame 26 on the linear drive 28 to move the bagging film 17 to the left. . When the film feeding device passes the bag-making film 17 on the film pad 22 at a certain speed, the print head 24 will start printing the set content on the bag-making film 17, and can print multiple pieces continuously according to the set interval. The printed content of the bag is on the bag-making film 17. Such as figure 2 As shown, when the leftward movement of the film pulling frame 26 ends, the film pressing cylinder 27 is retracted and the bag-making film 17 is released. The electric motor 21 drives the film pulling frame 26 on the linear drive 28 to quickly move to the right and return to the original position. Complete a work cycle. Only 3 prints are printed in one work cycle in the figure. However, according to the requirements of the production line, multiple printing contents such as 2, 4, 5, and 6 bags can be printed in one working cycle. The film storage device includes a linear guide rail pair 210, a film storage weight 211, a lowest position detection switch 212, a highest position detection switch 213, a first film storage drum 29 and a second film storage drum 291. The bag-making film 17 is wound around the first On the film storage drum 29, the film storage weight 211, and the second film storage drum 291, the film storage weight 211 is located between the first film storage drum 29 and the second film storage drum 291, and the film storage weight 211 follows the linear guide rail. The sub 210 moves between the lowest position detection switch 212 and the highest position detection switch 213. When the film storage weight 211 of the film storage device drops to the lowest position detection switch 212, the film feeding device and the smart coding system stop working, and when the film storage weight 211 of the film storage device rises away from the lowest position detection switch 212 , The film feeding device and the intelligent coding system start to work. When the film storage weight 211 of the film storage device rises to the highest position detection switch 213, the film pulling mechanism 3 is like Figure 8 As shown, the work is stopped, waiting for the smart printing mechanism 2 to send the printed bag-making film 17 and the film storage weight 211 is lowered away from the highest position detection switch 213. The film feeding device of this embodiment adopts a linear drive 28 to convey the bagging film 17, which can ensure that the width direction position of the bagging film 17 will not be offset, and also ensure that the actual film length and the theoretical film length are small. Ensure that the position of the printing content is accurate, located in the middle of the large infusion soft bag package 18, such as Figure 7 Shown. The intelligent coding system (for example, Domino A300+ coding machine) used in the present invention can print real-time variables, such as production date, batch number, and expiration date, and can print bar codes, which belong to the prior art. The circuit involved in the present invention is also the prior art, and will not be repeated here.

Example Embodiment

[0054] Example 3: Such as Figure 4 with Figure 5 As shown, the smart coding system is fixed on the printing frame 23, wherein the width direction of the print head 24 is the same as the width direction of the bag-making film 17. The film feeding device is installed in front of the print head 24 (take the direction of movement of the bag-making film as a reference), and the film storage device is installed in front of the film feeding device. Figure 4 Shown. The film feeding device includes an electric motor 21, an active film feeding roller 31, a driven film feeding roller 32, a pressure regulating device 33, and a transmission system 34. The active film feeding roller 31 and the driven film feeding roller 32 are arranged oppositely and in opposite directions. The output end of 21 is connected to the active film feeding roller 31, and the active film feeding roller 31 is connected to the driven film feeding roller 32 through a transmission system 34. The pressure adjusting device 33 is installed above the driven film feed roller 32. The electric motor 21 can also be a servo motor or a stepping motor, and the pressure adjusting device 33 can adjust the pressing force of the active film feeding roller 31 and the driven film feeding roller 32 on the bag film 17. The transmission system 34 transmits the power on the active film feed roller 31 to the driven film feed roller 32 and makes the rotation direction of the driven film feed roller 32 opposite to the rotation direction of the active film feed roller 31. When starting to work, the electric motor 21 drives the active film feed roller 31 to rotate counterclockwise as Figure 4 As shown, the power is transmitted to the driven film feeding roller 32 through the transmission system 34 at the same time, so that it rotates clockwise. Since the pressure adjusting device 33 applies pressure to the driven film feeding roller 32, the bag film 17 is subjected to two feedings. The pressure of the film roller moves to the left under the action of friction. The film storage device includes a linear guide rail pair 210, a film storage weight 211, a lowest position detection switch 212, a highest position detection switch 213, a first film storage drum 29 and a second film storage drum 291. The bag-making film 17 is wound around the first On the film storage drum 29, the film storage weight 211, and the second film storage drum 291, the film storage weight 211 is located between the first film storage drum 29 and the second film storage drum 291, and the film storage weight 211 follows the linear guide rail. The sub 210 moves between the lowest position detection switch 212 and the highest position detection switch 213. When the film feeding device feeds the bag-making film 17 on the film pad 22 at a certain speed, the print head 24 will start printing the set content on the bag-making film 17, which can continuously print at the set interval. The printed content of each bag is printed on the bag-making film 17 as Figure 6 Shown. When the film storage weight 211 of the film storage device drops to the lowest position detection switch 212, the film feeding device and the smart coding system stop working, and when the film storage weight 211 of the film storage device rises away from the lowest position detection switch 212 , The film feeding device and the intelligent coding system start to work. When the film storage weight 211 of the film storage device rises to the highest position detection switch 213, the film pulling mechanism 3 is like Figure 8 As shown, the work is stopped, waiting for the smart printing mechanism 2 to send the printed bag-making film 17 and the film storage weight 211 is lowered away from the highest position detection switch 213. The film feeding device of this embodiment adopts the film feeding roller to convey the bag-making film, so that the printer occupies a small space and has a compact structure. The intelligent coding system (for example, Domino A300+ coding machine) used in the present invention can print real-time variables, such as production date, batch number, and expiration date, and can print bar codes, which belong to the prior art. The circuit involved in the present invention is also the prior art, and will not be repeated here.
[0055] In the foregoing embodiments, the maximum print height L is limited by the width of the print head 24, that is, the maximum print height L = the width of the print head 24, such as Figure 6 Shown. If the width of the print head 24 differs greatly from L, two print heads 24 or multiple print heads can be installed, so that the sum of the widths of the multiple print heads 24 = the maximum printing height L.

The smart printing mechanism 2 is fixed on the frame 16 and is located between the film feeding mechanism 1 and the film pulling mechanism 3. When the film feeding mechanism 1 and the film pulling mechanism 3 or the film feeding device of the smart printing mechanism 2 will make the bag film 17 When a certain speed passes the print head 24 of the smart printing mechanism 2, the smart printing mechanism 2 starts to work and prints the set printing content on the bag-making film 17. At the same time, the film feeding mechanism 1 sends out the bag-making film to ensure that the bag-making film 17 is always pulled out by the film feeding device of the film-pulling mechanism 3 or the smart printing mechanism 2 when the bag-making film 17 is always in a tensioned state. At the same time, the film-drawing mechanism 3 sends the bag-making film 17 with the printed content to the bag-making forming mechanism 4 to complete the bag-making forming.
