[0032] like Figure 3 As shown, the lifting device 6 includes a cylinder 61, which is fixedly installed on the bracket 1, and a plurality of support plates 12 are fixedly installed on the bracket 1. A lifting shaft 62 is fixedly installed on the output end of the cylinder 61, and the lifting shaft 62 passes through the support plate 12. The lifting shaft 62 is slidably connected to the support plate 12, and one end of the lifting shaft 62 is fixed with a mounting plate 65 by a bolt.

[0033] Specifically, the lifting shaft 62 passes through the needle knife 3 and is fixedly connected to the needle knife 3. The lifting shaft 62 is provided with a first spring 63, which is arranged between the needle knife 3 and the support plate 12. One end of the first spring 63 is fixed to the support plate 12, and the other end is fixed to the bottom of the needle knife 3.

[0034] In this embodiment, the cylinder 61 drives the lifting shaft 62 to descend, and the lifting shaft 62 drives the needle knife 3 to descend. After the short needle at the bottom of the needle knife 3 pierces the bubble cotton on the material receiving plate 11, the cylinder 61 drives the lifting shaft 62 to rise, and the lifting shaft 62 drives the needle knife 3 to rise. During the movement of the needle knife 3, the first spring 63 and the second spring 64 are used in conjunction with the damper to reduce the shock of the equipment.

[0035] like Figure 1-Figure 2 As shown, the lifting device 6 is connected to the hot pressing blade 4. The hot pressing blade 4 is a plate-like structure with a heating component installed inside. The plate-like structure includes but is not limited to a resistance wire heating plate and a quartz heating plate. Among them, the lifting shaft 62 passes through the hot pressing blade 4 and is fixedly connected to the hot pressing blade 4. The lifting shaft 62 is provided with a first spring 63, which is arranged between the hot pressing blade 4 and the support plate 12. One end of the first spring 63 is fixed to the support plate 12, and the other end is fixed to the bottom of the hot pressing blade 4.

One end of the second spring 64 is fixed to the mounting plate 65, and the other end is fixed to the top of the hot pressing blade 4.

[0036] Specifically, such as Figure 6 、 Figure 11 As shown, the hot pressing knife 4 includes a straight portion 42, one end of the straight portion 42 is connected to the outward expansion portion 41, the straight portion 42 is used to form a separation straight line 7 on the bubble cotton strip, and the outward expansion portion 41 is used to form a separation oblique line 8 on the bubble cotton strip.

[0037] In this embodiment, the cylinder 61 drives the lifting shaft 62 to descend, and the lifting shaft 62 drives the hot pressing knife 4 to descend. The hot pressing knife 4 hot presses the bubble cotton on the supporting plate 11, so that a separating straight line 7 and a separating oblique line 8 are formed in the area of ​​the bubble cotton strip punctured by the needle knife 3. The upper and lower layers of film of the bubble cotton strip are bonded at the separating straight line 7 and the separating oblique line 8. After bonding, the cylinder 61 drives the lifting shaft 62 to rise again, and the lifting shaft 62 drives the hot pressing knife 4 to rise. During the movement of the hot pressing knife 4, the first spring 63 and the second spring 64 are used in conjunction with the damper to reduce the shock of the equipment.

[0038] like Figure 1-Figure 2 As shown, the lifting device 6 is connected to the cutter 5, and conveying rollers 2 are provided on both sides of the cutter 5. The conveying rollers 2 are used to convey the bubble cotton strip, and the cutter 5 is used to cut the bubble cotton strip along the dividing straight line 7 and the dividing oblique line 8.

[0039] Specifically, such as Figure 4 As shown, the lifting shaft 62 passes through the cutter 5 and is fixedly connected to the cutter 5. The lifting shaft 62 is provided with a first spring 63, which is arranged between the cutter 5 and the support plate 12. One end of the first spring 63 is fixed to the support plate 12, and the other end is fixed to the bottom of the cutter 5. The lifting shaft 62 is also provided with a second spring 64, which is arranged between the cutter 5 and the mounting plate 65. One end of the second spring 64 is fixed to the mounting plate 65, and the other end is fixed to the top of the cutter 5.

[0040] like Figure 6 As shown, a blade 51 is provided at the bottom of the cutter 5 . The blade 51 is a strip-shaped blade structure with an outwardly expanded end portion, and the shape of the blade 51 is adapted to the separating straight line 7 and the separating oblique line 8 .

[0041] In this embodiment, if Figure 4 As shown, the cylinder 61 drives the lifting shaft 62 to descend, and the lifting shaft 62 drives the cutter 5 to descend. The cutter 5 cuts the bubble cotton on the receiving plate 11, so that the bubble cotton strip is separated along the dividing straight line 7 and the dividing oblique line 8. After the bubble cotton strip is cut, the cylinder 61 drives the lifting shaft 62 to rise again, and the lifting shaft 62 drives the cutter 5 to rise. During the movement of the cutter 5, the first spring 63 and the second spring 64 are used in conjunction with the damper to reduce the shock of the equipment.

[0042] When in use, the folded bubble cotton film strip roll is placed on one side of the equipment, and the bubble cotton film strip is conveyed by the conveying roller 2. During the conveying process, the needle knife 3, the hot pressing knife 4 and the cutter 5 rise and fall at the same time. The bubble cotton strip is first punctured by the needle knife 3, and then the hot pressing knife 4 performs hot pressing on the punctured area of ​​the bubble cotton strip. Repeated hot pressing of multiple hot pressing knives 4 can improve the bonding effect of the upper and lower layers of the bubble cotton strip. A separation straight line 7 and a separation oblique line 8 are formed on the bubble cotton strip after hot pressing, and then the bubble cotton strip is cut along the separation straight line 7 and the separation oblique line 8 by the cutter 5. The cut bubble cotton strip is cut along Figure 12 After the dotted line in the figure is unfolded, a three-dimensional bubble cotton packaging bag is formed.

[0043] The inventors discovered that Figures 8-10 As shown, the dividing line on the bubble cotton strip is usually a straight line (i.e., the dividing line 7), so that the produced bubble cotton packaging bag is flat, and the bottom is linear and cannot stand vertically on the table, resulting in the internal space of the bubble cotton packaging bag being narrow, the capacity being small, and it is not convenient to place it vertically on the table.

[0044] In this application, if Figure 8 、 Figure 11-12 As shown, the bubble cotton packaging bag produced by the equipment is three-dimensional after being unfolded. Compared with the flat packaging bag, the unfolded packaging bag has a larger internal space and capacity. The bottom of the bubble cotton packaging bag can be unfolded into a flat surface, which is convenient for standing vertically on the table.

[0045] Working principle: When in use, place the folded bubble cotton film strip roll on one side of the equipment, and convey the bubble cotton film strip through the conveyor roller 2. During the conveying process, the needle knife 3, the hot pressing knife 4 and the cutter 5 rise and fall at the same time. The bubble cotton strip is first punctured by the needle knife 3, and then the hot pressing knife 4 performs hot pressing on the punctured area of ​​the bubble cotton strip. Repeated hot pressing by multiple hot pressing knives 4 can improve the bonding effect of the upper and lower layers of the bubble cotton strip. After hot pressing, a separation straight line 7 and a separation oblique line 8 are formed on the bubble cotton strip, and then the cutter 5 cuts the bubble cotton strip along the separation straight line 7 and the separation oblique line 8. The cut bubble cotton strip is cut along the Figure 12 After the dotted line in the figure is unfolded, a three-dimensional bubble cotton packaging bag is formed.

[0046] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
