For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] An embodiment of the film splicing device of the utility model packaging machine: Figure 1 As shown, the packaging machine includes a frame 1, a film loading roller 2 installed at both ends in the frame 1 for mounting a packaging material roll 14, and a film feeding roller 5 installed at both ends in the frame 1 and located below the film loading roller 2, and the film feeding roller 5 is located in front of the film loading roller 2. The film splicing device includes a film splicing plate 8, a support plate 13, a tape roller 6, a tape roll 7, a support seat 15, a tape feeding roller 11, and a cutting tooth 12, which are specifically described as follows.

[0026] One end of the film-joining plate 8 is installed in the frame 1, and the other end is connected to the support plate 13. The film-joining plate 8 is located below the film-loading roller 2 and above and behind the film-feeding roller 5, that is, between the film-loading roller 2 and the film-feeding roller 5 in the vertical direction and behind the film-feeding roller 5 in the horizontal direction.

[0027] In specific implementation, the film splicing plate 8 is placed horizontally or slightly tilted forward and downward, and the edges of the packaging films 4 of the new and old packaging material rolls 14 can be spread on the upper surface of the film splicing plate 8, thereby facilitating the operation of butt-jointing and pasting the packaging films 4.

[0028] The front side of the support plate 13 is provided with a tape roller 6 and a support seat 15 .

[0029] The rear end of the tape roller 6 is connected to the support plate 13 and is located on a side of the support plate 13 away from the film splicing plate 8 , on which a tape roll 7 is mounted.

[0030] In specific implementation, the film splicing plate 8 is placed horizontally or tilted forward and downward, the support plate 13 is placed perpendicular to the film splicing plate 8, the central axis of the tape roller 6 is perpendicular to the support plate 13, that is, parallel to the film splicing plate 8, and the tape roller 6 can rotate along the central axis, so that the tape can be stretched parallel to the film splicing plate 8. In addition, the tape roll 7 is clamped on the outer periphery of the tape roller 6 to facilitate the use of the tape.

[0031] The support seat 15 is located between the tape roller 6 and the film connecting plate 8, and a tape feed roller shaft 11 and cutting teeth 12 are installed on it; the axis of the tape feed roller shaft 11 is installed on the support seat 15 and can rotate along the central axis, and is located between the tape roller 6 and the cutting teeth 12.

[0032] The cutting teeth 12 are arranged parallel to the central axis of the tape feed roller 11 so as to cut perpendicularly to the tape.

[0033] During specific implementation, the film joining plate 8 is placed horizontally or tilted forward and downward, the support plate 13 is placed perpendicular to the film joining plate 8, the central axis of the tape feed roller 11 is perpendicular to the support plate 13, that is, parallel to the film joining plate 8, and the tape feed roller 11 can rotate along the central axis to facilitate the stretching of the tape parallel to the film joining plate 8.

[0034] In addition, the tape feed roller 11 is located between the tape roller 6 and the cutting teeth 12. On the one hand, the tape feed roller 11 plays a guiding role, which facilitates the tape to be stretched along the tape feed roller 11 to the top of the film splicing plate 8 to align the edges of the new and old packaging films 4. On the other hand, since it is troublesome to peel off the head end of the tape roll 7, the tape feed roller 11 is provided, and the head end of the tape roll 7 is glued to the tape feed roller 11 for easy access.

[0035] In addition, after the new and old packaging material rolls 14 are butted together, the tape can be quickly cut using the cutting teeth 12 without the need to find another cutting tool, which also makes it convenient to take the tape for the next film splicing operation.

[0036] When the utility model is used, Figure 3 As shown, when the end of the packaging film 4 of the old packaging material roll 14 leaves the film loading roller 2 and is spread onto the film splicing plate 8, a new packaging material roll 14 is replaced on the film loading roller 2, and the head end of the packaging film 4 of the new packaging material roll 14 is also spread onto the film splicing plate 8, with the new packaging film 4 on top and the old packaging film 4 on the bottom. Then, the adhesive tape on the tape roll 7 is pulled toward the film splicing plate 8, and the tape roller 6 rotates with the adhesive tape, so that the adhesive tape extends a sufficient length under the guidance of the tape feeding roller 11 and is located above the film splicing plate 8. Next, the edges of the new and old packaging films 4 are pasted together using the adhesive tape, thereby completing the film splicing operation. Afterwards, the adhesive tape is cut off by the cutting teeth 12, and the new packaging film 4 can enter the film feeding roller 5 from the film splicing plate 8 downward, and then the packaging operation is completed.

[0037] It can be seen from the above technical solution that the tape roll 7 is fixed on the tape roller 6, which is easy to take and use, and the film splicing operation only needs to pull out the tape and stick the edges of the new and old packaging films 4 on the film splicing plate 8 together, which is convenient to operate, saves manpower and improves work efficiency.

[0038] In other specific embodiments of the present invention, the rest is the same as the above embodiments, except that: Figure 1 As shown, the utility model also includes a film pressing roller 3 with both ends mounted on the inner wall of the frame 1; the film pressing roller 3 is located below the film loading roller 2 and above and behind the film connecting plate 8, that is, it is located between the film connecting plate 8 and the film loading roller 2 in the vertical direction, and is located behind the film connecting plate 8 in the horizontal direction.

[0039] During specific implementation, the film pressing roller 3 can press down the packaging film 4 extending from the packaging material roll 14 on the film loading roller 2 to make it easier for the packaging film 4 to be spread out evenly on the film splicing plate 8 and avoid damage to the packaging film 4 .

[0040] In other specific embodiments of the utility model, the rest are the same as the above-mentioned embodiments, except that the vertices of the tape roller 6, the tape feed roller 11, and the cutting teeth 12 are flush with the upper surface of the film joining plate 8, so that the tape stretched from the tape roller 6 can easily approach the packaging film 4 on the film joining plate 8, thereby shortening the distance of the pasting operation.

[0041] In other specific embodiments of the present invention, the rest is the same as the above embodiments, except that: Figure 2 and Figure 3 As shown, the tape roller 6 includes a central shaft 9 and supporting blades 10 ; the rear end of the central shaft 9 is connected to a supporting plate 13 ; the supporting blades 10 are evenly sleeved on the central shaft 9 and can rotate along the central shaft 9 .

[0042] In specific implementation, the distance from the edge of the support blade 10 to the center of the central axis 9 is the same as the inner diameter of the tape roll 7. The inner ring of the tape roll 7 itself has a certain elasticity and can be clamped on the tape roller 6. There are at least three support blades 10, which can be adjusted according to the situation so as to be able to clamp the tape roll 7.

[0043] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
