Description

Technical Field

[0001] The utility model relates to the technical field of side sealing machines, in particular to a film spreading structure for side sealing machines. Background Art

[0002] In modern industrial production, the side sealing machine is an automated equipment for packaging materials, which can seal the films on both sides of the sheet, thereby improving the sealing and aesthetics of the packaging. However, the existing side sealing machine has some technical difficulties in flattening the films on both sides of the sheet. Specifically, when the film is side-sealed, the upper film and the lower film are bonded together by the heat pressing of the heat pressing assembly. In order to achieve the bonding of the upper film and the lower film, the upper film and the lower film need to be blown open by the blowing nozzle first, so that the area is large enough to ensure that the upper film and the lower film are bonded together. However, in this way, when the upper film and the lower film are blown open by the blowing nozzle, the lower film is easy to roll inwards because there is no obstruction, resulting in the upper film and the lower film not being bonded together during the heat pressing, and the side sealing quality is poor. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a film spreading structure for a side sealing machine, which can move quickly and flatten the film on the outer side of the plate during the movement so that the side sealing can be performed smoothly.

[0004] To achieve the above purpose, the utility model adopts the following technical solution: a film spreading structure for a side sealing machine, comprising:

[0005] Install beams;

[0006] A spur rack fixed to the side of the mounting beam;

[0007] A guide rail, which is also fixed to the side of the mounting beam, and is parallel to the spur rack;

[0008] A pair of rotating cylinders are respectively located on the left and right sides of the mounting beam and are slidably connected to the guide rails. A driving motor is fixed on the top of each rotating cylinder. A driving gear is fixedly connected to the driving motor. The driving gear is meshed with a spur rack. A film spreading plate is fixed on the rotating rod of the rotating cylinder.

[0009] Furthermore, an upper mounting bar and a lower mounting bar are fixed on the mounting beam, the upper mounting bar is mounted with a spur rack by screws, and the lower mounting bar is mounted with a guide rail by screws.

[0010] Furthermore, the spur rack includes a first side bar and a second side bar, and the guide rail includes a first side rail and a second side rail.

[0011] Furthermore, the rotary cylinder is fixedly connected to the drive motor via a mounting bracket.

[0012] Furthermore, the joints between the front plate and the side plates, and the joints between the rear plate and the side plates of the film-expanding plate are all rounded.

[0013] Principle of the utility model:

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] First, the film spreading structure can move quickly, and during the movement, it can block the upper film and the lower film on both sides of the plate, so that when the blowing nozzle blows air, the upper film and the lower film will not be rolled inward, so that they can be smoothly flattened, thereby ensuring that they can perform accurate side sealing;

[0016] Second, through the setting of the spur rack, the driving motor can drive the rotary cylinder to move left and right, so that the spreading plate on it has a larger range of action, ensuring the flattening effect of the film;

[0017] Thirdly, since the joints between the front plate and the side plates, as well as the joints between the rear plate and the side plates of the film spreading board are all rounded, the film will not be scratched when the film spreading board rotates, thus effectively ensuring the integrity of the film.

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-3 As shown, the embodiment of the utility model proposes the following Figure 1-3As shown, the embodiment of the utility model provides a film spreading structure for a side sealing machine, comprising:

[0025] Mounting beam 1; the mounting beam is mounted on the bracket of the residual material conveyor of the side sealing machine, and is raised and lowered along with the raising and lowering of the residual material conveyor;

[0026] A spur rack 2, wherein the spur rack 2 is fixed to the side of the mounting beam 1;

[0027] A guide rail 3, which is also fixed on the side of the mounting beam 1, and is parallel to the spur rack 2;

[0028] A pair of rotating cylinders 4 are respectively located on the left and right sides of the mounting beam 1 and are slidably connected to the guide rail 3. A driving motor 5 is fixed on the top of each rotating cylinder 4. A driving gear 6 is fixedly connected to the driving motor 5. The driving gear 6 is meshed with the spur rack 2. A film spreading plate 7 is fixed on the rotating rod of the rotating cylinder 4.

[0029] The process of the utility model when in use is as follows: first, the film spreading structure is installed on the side sealing machine, specifically, it is installed on the bracket of the residual material conveyor of the side sealing machine. When the plate enters from the side sealing machine, the film will cover the upper and lower surfaces of the plate, and the residual material conveyor on the left and right sides of the plate is installed with the film spreading structure, and the residual material conveyor drives the film spreading structure to rise. When rising, the film spreading plate 7 on the rotating rod on the rotating cylinder begins to rotate, and its rotation angle is 90 degrees, so that it is located between the upper film and the lower film. At this time, the blowing nozzle blows in between the upper film and the lower film. At this time, due to the obstruction of the film spreading plate 7, the upper film and the lower film will not be rolled inward under the action of the blowing nozzle. At this time, driven by the driving motor 5, the rotating cylinder 4 moves forward until the film spreading plate 7 leaves the upper film and the lower film, and finally the hot pressing component on the side sealing machine hot-presses and bonds the upper film and the lower film.

[0030] Furthermore, an upper mounting bar 8 and a lower mounting bar 9 are fixed on the mounting beam 1, and the upper mounting bar 8 is mounted with a spur rack 2 by screws, and the lower mounting bar 9 is mounted with a guide rail 3 by screws. Specifically, the mounting beam 1 of the utility model is fixed with an upper mounting bar 8 and a lower mounting bar 9, which are used to mount the spur rack 2 and the guide rail 3, respectively, to ensure that the film spreading plate 7 can move horizontally.

[0031] Furthermore, the spur rack 2 includes a first side bar 12 and a second side bar 13, and the guide rail 3 includes a first side rail 14 and a second side rail 15. Specifically, the spur rack 2 of the utility model is composed of two parts, including the first side bar 12 and the second side bar 13, and the guide rail 3 includes the first side rail 14 and the second side rail 15, wherein the driving motor 5 only needs to move a certain distance at each end of the mounting beam 1 to achieve the effect of blocking the lower film, so the spur rack 2 is set as the first side bar 12 and the second side bar 13, and the guide rail 3 is set as the first side rail 14 and the second side rail 15.

[0032] Furthermore, the rotating cylinder 4 is fixedly connected to the driving motor 5 via a mounting bracket 11. The rotating cylinder 4 of the utility model is fixedly connected to the driving motor 5 via the mounting bracket 11. When the rotating cylinder 4 rotates, the film spreading plate 7 can be driven to rotate. At the same time, in order to prevent the edge of the film spreading plate 7 from scratching the lower film, the joints between the front plate and the side plate of the film spreading plate 7, and the joints between the rear plate and the side plate are all rounded 10.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
