Abstract
Description
Technical Field
[0001] The utility model relates to a packaging machine, in particular to a film supply device for providing a film. Background Art
[0002] The pillow packaging machine is a device that packages blister tablets with film. It includes a film supply device, which is used to supply film. The film supply device usually supplies film from a roll. As the market demands for increased production speed and efficiency, the speed of pillow packaging machines continues to increase, and the film supply is changed to two rolls. At the same time, an automatic film splicing device is designed between the two rolls. Figure 2 As shown in the figure, the traditional automatic film splicing device is to connect two film splicing rollers together in the horizontal direction. However, this automatic film splicing device has some disadvantages when used on a high-speed pillow packaging machine: 1. Since the end of the film is placed on one film splicing roller, when the film splicing roller moves horizontally, the position of the film end on the film splicing roller will change significantly, affecting the accuracy of film splicing; 2. There is no cutting mechanism, and the overlapping part of the two films is too long during film splicing, and too many empty bags need to be rejected; 3. During film splicing, the film moves too fast, resulting in a low success rate of film splicing. Summary of the Invention
[0003] In view of the deficiencies in the prior art, the utility model innovatively provides an automatic film splicing and supplying device with higher film splicing accuracy.
[0004] The lifting mechanism is a bottom end of the lifting mechanism, and the lifting mechanism is a bottom end of the lifting mechanism, and the lifting mechanism is a bottom end of the lifting mechanism.
[0005] The upper end of the first film splicing seat is connected to a first film splicing upper roller, and the upper end of the second film splicing seat is connected to a second film splicing upper roller.
[0006] The first cutting mechanism is located behind the first film splicing mechanism, and the first cutting mechanism includes a first cutter and a first cutting power source that drives the first cutter to perform a cutting action; the second cutting mechanism is located behind the second film splicing mechanism, and the second cutting mechanism includes a second cutter and a second cutting power source that drives the second cutter to perform a cutting action.
[0007] According to an automatic film splicing and supplying device provided by the utility model, by docking the ends of the film in a rotating manner, the length of the double-sided tape bonding section on the film does not change, and the double-sided tape does not move on the film splicing roller. In this way, the film splicing position is accurate and reliable, and the film splicing success rate is very high. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 This is the principle diagram of the film connection of the utility model;
[0009] Figure 2 This is a schematic diagram of the film connection principle of the existing film supply device. DETAILED DESCRIPTION
[0010] like Figure 1 As shown, this automatic film splicing film supply device includes an organic base (not shown), a first film supply station 1 and a second film supply station 2. The first film supply station 1 is provided with a first cutting mechanism and a first film splicing mechanism, the first film splicing mechanism includes a first film splicing seat 14 and a first film splicing lower roller 16, the middle position of the first film splicing seat 14 is rotatably mounted on the machine base via a first rotating shaft 15, the first film splicing lower roller 16 is connected to the lower end of the first film splicing seat 14, the first film splicing seat 14 is transmission-connected to a first film splicing power source that drives the first film splicing seat 14 to rotate (the first film splicing power source is not shown); similarly, the second film supply station 2 is provided with a second cutting mechanism and a second film splicing mechanism, the second film splicing mechanism includes a second film splicing seat 24 and a second film splicing lower roller 26, the second film splicing seat 24 is The middle position is rotatably mounted on the machine base through the second rotating shaft 25, and the second film splicing lower roller 26 is connected to the lower end of the second film splicing seat 24, and the second film splicing seat 24 is transmission-connected to the second film splicing power source that drives the second film splicing seat 24 to rotate (the second film splicing power source is not drawn); driven by the first film splicing power source and the second film splicing power source (the first film splicing power source and the second film splicing power source can be two independent power sources or the same power source, and the same power source synchronously drives the first rotating shaft 15 and the second rotating shaft 25 to rotate), the first film splicing lower roller 16 and the second film splicing lower roller 26 are close together and the films are spliced together.
[0011] The film bonding principle is as follows: Figure 1 As shown, the two rolls of film are placed on the film bearing shafts on both sides and are pressed Figure 1When the left working film roll is used up, a detection device sends a signal to prepare the right spare film for splicing. The first splicing power source and the second splicing power source drive the first splicing seat 14 and the second splicing seat 24 to rotate ( Figure 1 The two rotating shafts rotate in the direction of the film splicing), the upper end of the first film splicing seat 14 moves obliquely downward, the first film splicing lower roller 16 moves obliquely upward, the upper end of the second film splicing seat 24 moves obliquely downward, and the second film splicing lower roller 26 moves obliquely upward, so that the first film splicing lower roller 16 and the second film splicing lower roller 26 move correspondingly to each other, and the two rolls of film with double-sided tape 3 are bonded together. At the same time as the film splicing roller action is completed, the first cutting mechanism 12 on the working side is actuated to cut off the remaining part of the film on the working side (including the tape at the tail), and the film splicing action is completed. After receiving the film splicing action instruction, the machine removes this section of the pillow bag product as needed. The advantages of this automatic film splicing film supply device are as follows: 1. According to Figure 1 As can be seen from the film with the bold line in the middle, when the film splicing mechanism is in the separated and joined states, the upper and lower ends of the film splicing seat move in opposite directions, so the length of the double-sided tape joint does not change, and the position on the film splicing roller does not move. The film splicing position is precise and reliable, and the film splicing success rate is very high. 2. The high-speed film splicing machine is equipped with a cutting mechanism. After the pillow film is exhausted, the remaining film on the working side (including the tail tape) is cut off. The joint sections of the two film rolls are neat and the overlap is appropriate. Only a few waste bags need to be removed, saving film. At the same time, because there is no tail tape after cutting, the film splicing success rate is greatly improved.
[0012] In order to make the film move smoothly on the film seat, Figure 1 As shown, the first film splicing upper roller 13 is connected to the upper end of the first film splicing seat 14, and the second film splicing upper roller 23 is connected to the upper end of the second film splicing seat 24. The first film splicing upper roller 13 and the first film splicing lower roller 16 on the first film splicing seat 14 support the film. Since both are in point contact, the film moves more smoothly on the first film splicing seat 14. Similarly, the second film splicing upper roller 23 and the second film splicing lower roller 26 support the film. Since both are in point contact, the film moves more smoothly on the second film splicing seat 24.
[0013] Finally, it is worth mentioning that the first cutting mechanism is located behind the first film splicing mechanism. The first cutting mechanism includes a first cutter 12 and a first cutting power source (not shown) that drives the first cutter 12 to cut. By driving the first cutting power source, the first cutter 12 is actuated to cut the film; the second cutting mechanism is located behind the second film splicing mechanism. The second cutting mechanism includes a second cutter 22 and a second cutting power source (not shown) that drives the second cutter 22 to cut. By driving the second cutting power source, the second cutter 22 is actuated to cut the film.
