Description

Technical Field

[0002] Horizontal packaging machine, also known as pillow packaging machine, uses a continuous roll of film to package materials that are continuously input at intervals. The roll of film is wound around the material through a film former, and the seams of the two sides of the roll of film are sealed by a center sealing mechanism. Then, the roll of film that wraps the material is cut and sealed at the end by a horizontal sealing device.

[0003] The existing horizontal sealing devices for horizontal packaging machines all seal the tail end of the previous package of materials and the front end of the next package of materials, and then the cutter in the horizontal sealing device cuts the two packages of materials. The existing horizontal sealing devices with such sealing structures cannot meet the special packaging requirements of products. For example, the product output by the horizontal sealing device is required to be sealed on one side and not sealed on the other side to form an open packaging, so as to facilitate the subsequent vacuum shrinkage of the single-side sealed package output by the horizontal sealing device.

[0004] If only the structure of the existing transverse sealing device is improved, and the hot sealing blocks on both sides of the cutter are heated on one side and not heated on the other side, the above-mentioned special packaging requirements can be met. However, since the packages output by the transverse sealing device have openings, such structural improvements alone cannot ensure the smoothness of the incision, which will affect the packaging effect of the packages.

[0039] Refer to the instruction manual Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, when the upper transverse sealing assembly 1 and the lower transverse sealing assembly 2 are driven to engage with each other by the transverse sealing driving assembly, the film pressing assembly 5 moves downward with the upper transverse sealing assembly 1, and the bottom end surface of the film pressing assembly 5 is lower than the bottom end surface of the upper transverse sealing knife seat 3 of the upper transverse sealing assembly 1, so that the film pressing assembly 5 contacts the roll film 6 before the upper transverse sealing knife seat 3, so as to maintain the tension of the roll film 6 during the process of the upper transverse sealing assembly 1 and the lower transverse sealing assembly 2 engaging to seal and cut the film.

[0040] Example 2

[0041] As another preferred embodiment of the present utility model, this embodiment is based on the above-mentioned embodiment 1, and further elaborates and supplements the technical solution of the present utility model. Figure 3 As shown, the upper horizontal sealing knife seat 3 of the upper horizontal sealing component 1 and the lower horizontal sealing knife seat 4 of the lower horizontal sealing component 2 are separated by the cutter 7. The upper horizontal sealing knife seat 3 and the lower horizontal sealing knife seat 4 on one side of the cutter 7 are provided with a film-insulating pad 8, and the upper horizontal sealing knife seat 3 and the lower horizontal sealing knife seat 4 on the other side of the cutter 7 are provided with a knife pattern 9.

[0042] In this embodiment, according to the actual packaging processing requirements, the knife pattern 9 can be set on the right side and the film-insulating pad 8 can be set on the left side; or the knife pattern 9 can be set on the left side and the film-insulating pad 8 can be set on the right side.

A whole piece of transverse sealing knife seat can be used, so there is no need to heat half of it and not heat the other half. The whole piece of transverse sealing knife seat can be heated and the heat insulation pad can be used to isolate the heat. In this embodiment, knife lines are added to increase the lines at the sealing point when the roll film is heat-sealed to improve the sealing performance of the heat-sealed seal.

[0044] Example 3

[0045] As another preferred embodiment of the utility model, this embodiment is based on the above-mentioned embodiment 1 or embodiment 2, and further elaborates and supplements the technical solution of the utility model. Figure 1 , Attachment Figure 3 and attached Figure 4 As shown, the film pressing assembly 5 includes a film pressing rod 10 and a film pressing mounting plate 11.

[0046] In this embodiment, a cylindrical film pressing rod 10 is used for film pressing, which is conducive to the arc transition between the film pressing rod 10 and the film roll 6, and avoids the film pressing member with edges and corners from damaging the film roll 6 during the film pressing process. At the same time, such a structural mode is relatively easy to adjust and saves more parts costs.

[0047] The newly added film pressing assembly 5 in this embodiment has a simple structure and is easy to install. The structure of the film pressing assembly 5 of the utility model is convenient for modifying the existing transverse sealing device, and ensures the flatness of the cut when sealing the cut film roll 6. The film pressing assembly 5 of the utility model includes a film pressing rod 10 and a film pressing mounting plate 11.

[0048] As an example of this embodiment, the upper end of the film pressing mounting plate 11 is fixed to the upper tool holder 12 by connecting bolts, and a vertical waist-shaped hole 14 is provided at a position corresponding to the connecting bolts on the film pressing mounting plate 11. Through the vertical waist-shaped hole 14, the relative position between the film pressing mounting plate 11 and the upper tool holder 12, especially the downward extension length of the bottom of the film pressing rod 10, can be changed. By changing its installation position, the downward depth of the film pressing rod 10 can be adjusted. The bottom position of the film pressing rod 10 can be adjusted according to different packaging specifications, different roll film 6 materials, etc., to improve the adaptability of the film pressing assembly 5.

[0049] As another example of this embodiment, the end of the film pressing rod 10 is fixedly assembled on the film pressing mounting plate 11 through a nut, and a horizontal waist-shaped hole 15 is opened on the film pressing mounting plate 11 at a position corresponding to the position where the end of the film pressing rod 10 is assembled. The installation position of the film pressing rod 10, that is, the distance between the two film pressing rods 10, can be changed through the horizontal waist-shaped hole 15, so as to adapt to the changes in packaging specifications and the material of the roll film 6.

[0050] As another example of this embodiment, the film pressing rods 10 on both sides of the upper transverse sealing assembly 1 can be assembled on a set of film pressing mounting plates 11 to further simplify the structure of the film pressing assembly 5 and facilitate installation.

[0051] As another way of this embodiment, not shown in the figure, downwardly extending film pressing members can be arranged on both sides of the upper transverse sealing assembly 1, which can also play the role of film pressing, such as an inverted "L"-shaped plate, but compared with the film pressing rod 10 structure in the above embodiment, this L-shaped plate has lower adjustable flexibility and uses more materials.

At the same time, the continuous conveying and sealing of the roll film 6 can be realized without stopping the machine until the sealing is completed.

[0057] Furthermore, belt connecting plates 19 for connecting with the telescopic belt components on both sides of the transverse sealing device are installed on both sides of the transverse sealing mounting frame 16.
