Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] like Figure 1-5 As shown, a fireworks production labeling machine comprises a base 1, on which a lifting seat 2 is vertically slidably arranged, the bottom surface of the lifting seat 2 is a labeling surface, and the lifting seat 2 is provided with:

[0025] The label roll 91 and the waste roll 92 are respectively rolled up at two ends of the label material so that the label material is located on the labeling surface of the lifting seat 2;

[0026] The movable seat 3 is arranged to slide vertically, and a rotating frame 4 is rotatably arranged inside the movable seat 3. An extension portion 41 is arranged in a circular array on the rotating frame 4, and a pressing wheel 5 is rotatably arranged on the extension portion 41. The rotating frame 4 is driven to rotate so that the pressing wheel 5 rotates circumferentially with the rotating frame 4, and the pressing wheel 5 moves along the labeling surface of the lifting seat 2 to scratch the label material.

[0027] Specifically, Figure 1As shown, a conveyor belt 11 for conveying the fireworks box is provided on the base 1. The conveyor belt 11 is a well-known technology for those skilled in the art and will not be described in detail here. The base 1 is also provided with a driving cylinder 12 for driving the lifting seat 2 to perform vertical lifting. The label material is rolled on the label roll 91, and the end of the label material passes through the labeling surface of the lifting seat 2 and is rolled on the waste roll 92. The label is located on the labeling surface of the lifting seat 2. When the conveyor belt 11 transports the fireworks box to the bottom of the lifting seat 2, the lifting seat 2 is vertically lowered and the label moves and is attached to the fireworks box. At this time, the rotating The rotating frame 4 is driven to rotate so that the extension part 41 and the pressing wheel 5 rotate circumferentially, and the pressing wheel 5 contacts the fireworks box through the label material. At this time, the pressing wheel 5 rotates circumferentially, and the movable seat 3 is driven by the reaction force to slide vertically adaptively, so that the pressing wheel 5 moves along the labeling surface of the lifting seat 2 and scratches the back side of the label material, so that the label is rolled and pressed from one end to the other end by the pressing wheel 5 to stick to the fireworks box, thereby improving the attachment quality of the label and avoiding the problem of bubbles between the label and the fireworks box causing the label to fall off easily.

[0028] In the above technical solution, the pressing wheel 5 is used to press against the fireworks box through the label material, the rotating frame 4 is driven to rotate to make the pressing wheel 5 rotate circumferentially, and the movable seat 3 is driven by the reaction force to adaptively slide vertically, so that the pressing wheel 5 moves along the labeling surface of the lifting seat 2 and scratches the back side of the label material, so that the label is rolled and pressed from one end to the other end by the pressing wheel 5 to stick to the fireworks box, thereby improving the attachment quality of the label and avoiding the problem of bubbles between the label and the fireworks box causing the label to fall off easily.

[0029] As an embodiment further provided by the present invention, the rotating frame 4 has three groups of extension parts 41, and a first elastic member 31 is provided in the lifting seat 2 to drive the movable seat 3 to be in a low position. The movable seat 3 is in a low position and the rotating frame 4 is in a default state so that the two pressing wheels 5 are flush with the labeling surface of the lifting seat 2.

[0030] Specifically, Figure 2 As shown, the lifting seat 2 is driven by the first elastic member 31 to be in a low position, so that the rotating frame 4 is in a default state. At this time, the two pressing wheels 5 are flush with the labeling surface of the lifting seat 2, and the label material on the labeling surface of the lifting seat 2 is pushed and tightened by the pressing wheels 5, thereby further improving the flatness of the label during attachment and improving the label attachment quality.

[0031] The first elastic member 31 can be replaced by a spring, an elastic plate, an air bag or other elastic objects known to those skilled in the art.

[0032] As an embodiment further provided by the present invention, it also includes a driving seat 6, which is vertically movably arranged on the movable seat 3, and a resistance rod 71 is rotatably arranged on the driving seat 6, which is in an outward-turned shape in the default state, and a one-way tooth portion 42 is arranged on the rotating frame 4. The driving seat 6 is driven to slide to a low position so that the resistance rod 71 pushes the one-way tooth portion 42 to drive the rotating frame 4 to rotate, and the driving seat 6 is driven to slide to a high position so that the resistance rod 71 flips over and passes over the one-way tooth portion 42.

[0033] Specifically, Figure 2 As shown, the abutment portion 61 of the drive seat 6 is connected to the output end of the drive cylinder 12, as shown in FIG. Figure 4 As shown, the driving seat 6 is slidably arranged on the movable seat 3 through the sliding portion 62. The driving seat 6 is pushed by the driving cylinder 12 to drive the lifting seat 2 to slide vertically. When the driving cylinder 12 is extended to make the labeling surface of the lifting seat 2 contact the fireworks box, the driving cylinder 12 continues to extend to make the driving seat 6 slide relative to the movable seat 3. At this time, Figure 4 As shown, the resistance rod 71 is turned outward to push the one-way tooth portion 42, thereby driving the rotating frame 4 to rotate. At this time, the pressing wheel 5 on the rotating frame 4 can roll and press the label, and when the driving cylinder 12 contracts, the driving seat 6 slides to a high position so that the resistance rod 71 is pushed by the one-way tooth portion 42 and flipped to the side of the driving seat 6. At this time, the rotating frame 4 will not be driven to rotate, so that the driving seat 6 is used to realize the driven rotation of the rotating frame 4, simplifying the device structure and driving source, reducing costs and improving maintainability.

[0034] As a further embodiment provided by the present invention, a circumferential array of lower grooves 51 with arc-shaped cross sections is formed on the pressing wheel 5 .

[0035] Specifically, a circular array on the pressing wheel 5 is provided with lower grooves 51 with an arc-shaped cross-section. When the pressing wheel 5 rolls and presses the label, the lower grooves 51 can press the waste material roll of the label raw material to form a crease perpendicular to its forward direction, thereby avoiding the problem of the waste material roll being offset when being wound on the waste material roll 92 and causing the winding failure, thereby improving the winding quality of the waste material roll and improving the operating stability of the labeling machine.

[0036] As an embodiment further provided by the present invention, a second elastic member 63 for driving the driving seat 6 to slide and return to a high position is arranged in the movable seat 3 .

[0037] Specifically, the second elastic member 63 is arranged in the movable seat 3 to drive the driving seat 6 to slide and reset to a high position. The second elastic member 63 is used to drive the driving seat 6 to reset to improve the operating stability of the device. The second elastic member 63 can be replaced by a spring, an elastic plate, an airbag or other elastic objects known to those skilled in the art.

[0038] As a further embodiment of the present invention, a third elastic member 72 is provided on the driving seat 6 for driving the resisting rod 71 to return to an outward-turned shape.

[0039] Specifically, the third elastic member 72 is used to drive the resistance rod 71 to flip and reset to improve the operating stability of the device, wherein the third elastic member 72 can be replaced by a spring, an elastic plate, an airbag or other elastic objects known to those skilled in the art.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
