Detailed Implementation

[0021] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0023] Firework paper filling equipment is used to cut paper pieces from a paper strip and insert them into the firing holes of a firework bomb. However, with existing firework paper filling equipment, when the interval between the firing holes on the firework bomb is large, a large blank area is left between the punched holes after the paper strip is cut, resulting in low utilization of the paper strip and serious waste. Therefore, this application improves the existing firework paper filling equipment, which is described in detail below with reference to the accompanying drawings.

[0024] refer to Figures 1-3 The fireworks paper filling equipment includes a frame 10, a punching mechanism 20, a first roller mechanism 30 and a second roller mechanism 40, and a second drive device.

[0025] The punching mechanism 20 is arranged on the frame 10 and is used to punch out paper pieces from the paper strip 80 and push the paper pieces into the launching hole of the firework pyrotechnic 70. The first roller mechanism 30 and the second roller mechanism 40 are respectively arranged on both sides of the punching mechanism 20 to guide the paper strip 80 through the position of the punching mechanism 20.

[0026] The first roller mechanism 30 is arranged on the first side of the punching mechanism 20, and includes a first mounting frame 31, a plurality of first rollers 32, and a first drive device 33; the first rollers 32 and the first drive device 33 are mounted on the first mounting frame 31; the plurality of first rollers 32 together clamp the paper tape 80. The second roller mechanism 40 is arranged on the second side of the punching mechanism 20, and includes a second mounting frame 41 and a plurality of second rollers 42; the second rollers 42 are mounted on the second mounting frame 41; the plurality of second rollers 42 together clamp the paper tape 80.

[0027] The first driving device 33 drives the first roller 32 to rotate, pulling the paper strip 80 from the second side of the cutting mechanism 20 towards the first side, where the direction is the direction of movement of the paper strip 80. The second driving device drives the first roller mechanism 30 and the second roller mechanism 40 to adjust their positions in direction A, which is perpendicular to the direction of movement of the paper strip. In a specific example, the second driving device drives the first roller mechanism 30 and the second roller mechanism 40 to offset from their initial positions perpendicular to the direction of movement of the paper strip 80, or to return to their initial positions.

[0028] When the firework pellet is fed into the loading position at the bottom of the punching mechanism 20, the punching mechanism 20 punches out paper pieces from the paper strip 80 and pushes the paper pieces into the firing hole of the firework pellet 70. The punching mechanism is an essential component of the firework paper filling equipment. Exemplarily, the punching mechanism includes a paper insertion structure and a punching structure, wherein the punching structure is used to punch out paper pieces from the paper strip, and the paper insertion structure is used to push the paper pieces downward into the firing hole of the firework pellet.

[0029] A first roller mechanism 30 and a second roller mechanism 40 are respectively arranged on both sides of the punching mechanism 20. As the first roller mechanism 30 and the second roller mechanism 40 operate, the first roller mechanism 30 and the second roller mechanism 40 continuously drive and guide the paper tape 80 through the punching mechanism 20, so that the punching mechanism 20 can continuously punch out paper pieces on the paper tape.

[0030] Specifically, the first roller mechanism 30 is provided with multiple first rollers 32, through which the paper strip 80 can pass and be clamped. The second roller mechanism 40 is provided with multiple second rollers 42, through which the paper strip 80 can pass and be clamped. When the first drive device 33 drives the first rollers 32 to rotate, the first rollers 32 pull the paper strip 80 from the second side of the cutting mechanism 20 towards the first side. At the same time, the second rollers 42 guide the paper strip 80 into the cutting mechanism 20.

[0031] The first drive unit 33 may consist of one or more drive elements for driving one or more first rollers 32 to rotate. Figure 4 In the illustrated structure, the first drive device 33 includes only one drive element, which drives one of the first rollers 32 to rotate. The drive element can be an electric element or a pneumatic element, such as an electric motor or a pneumatic motor. In one specific embodiment, the first drive device 33 includes a servo motor.

[0032] In some embodiments of this application, reference is made to Figure 4 and Figure 5 The first roller mechanism 30 has two first rollers 32, and the paper strip 80 passes between the two first rollers 32 and is clamped by the two first rollers 32. The second roller mechanism 40 has two second rollers 42, and the paper strip 80 passes between the two second rollers 42 and is clamped by the two second rollers 42. The first drive device 33 is poweredly connected to one of the first rollers 32 to drive the first roller 32 to rotate.

[0033] The second drive device can drive the first roller mechanism 30 and the second roller mechanism 40 to offset or return to the initial position based on the initial position, perpendicular to the direction of movement of the paper tape 80. Therefore, under the drive of the second drive device, the first roller mechanism 30 and the second roller mechanism 40 can reciprocate between the initial position and the offset position.

[0034] In some embodiments of this application, the second driving device includes a first driving element 51 and a second driving element 52. The first driving element 51 drives the first roller mechanism 30 to move; the second driving element 52 drives the second roller mechanism 40 to move; under the drive of the first driving element 51 and the second driving element 52, the first roller mechanism 30 and the second roller mechanism 40 move synchronously. The first driving element 51 and the second driving element 52 can be configured as electric elements, pneumatic elements, etc., specifically as cylinders.

[0035] In some embodiments of this application, the second driving device is composed of a driving element, which simultaneously drives the first roller mechanism 30 and the second roller mechanism 40 to operate synchronously.

[0036] Based on the above configuration, the first driving device can drive the first roller 32 to rotate, thereby pulling the paper strip from the second side of the punching mechanism 20 towards the first side; the second driving device can drive the first roller mechanism 30 and the second roller mechanism 40 to offset perpendicular to the direction of movement of the paper strip 80 based on their initial positions. The paper strip 80 is clamped by the first roller 32 and the second roller 42 and will offset synchronously with the first roller mechanism 30 and the second roller mechanism 40. Therefore, the first driving device and the second driving device can drive the paper strip to adjust its position, so that the punching mechanism 20 can punch multiple pieces of paper in the same area on the paper strip. The punching holes of the multiple paper pieces are staggered, which improves the utilization rate of the paper strip and reduces costs.

[0037] In one embodiment of this application, the paper cutting positions of the cutting mechanism 20 are aligned in both the longitudinal and transverse directions, so that the cutting holes formed by the paper strip 80 after one cutting are aligned in both the longitudinal and transverse directions.

[0038] Figure 6 The diagram shows the punching holes formed after the punching mechanism 20 punches the same area of ​​the paper tape twice. Figure 6 In the diagram, the first cutting hole 81 is represented by a thick line, and the second cutting hole 82 is represented by a thin line. The first cutting hole 81 is formed after the cutting mechanism 20 performs a first cutting on the paper strip, and the first cutting holes 81 are aligned vertically and horizontally. Based on the first cutting, the cutting mechanism 20 performs a second cutting on the paper strip, forming the second cutting hole 82, which is also aligned vertically and horizontally.

[0039] After the first punching of the paper tape by the punching mechanism 20, first punching holes 81 are formed. Due to the large spacing between the first punching holes 81, there is a large unused blank area between them. The first driving device and the second driving device adjust the position of the paper tape by driving it, so that the punching mechanism 20 can be aligned with the blank area between the first punching holes 81 for a second punching. Finally, after two punchings, the paper tape forms first punching holes 81 and second punching holes 82.

[0040] The first drive device controls the position of the paper strip in its direction of movement, and the second drive device controls the lateral offset of the paper strip 80. The first and second drive devices can drive the paper strip to adjust its position, so that the punching mechanism 20 can punch the same area of ​​the paper strip twice. The punching holes of the two paper strip punches are staggered, which improves the utilization rate of the paper strip and reduces costs.

[0041] In some embodiments of this application, the fireworks paper filling device further includes a conveying mechanism 60; the conveying mechanism 60 is used to convey fireworks pellets. The conveying mechanism 60 passes through the punching mechanism 20; when the fireworks pellet on the conveying mechanism 60 moves to the position of the punching mechanism 20, the punching mechanism 20 punches out paper pieces on the paper belt 80 and pushes the paper pieces into the launching holes of the fireworks pellets. In a specific technical solution, the conveying mechanism 60 is a belt conveyor mechanism.

[0042] This application also provides a fireworks production line, which includes the fireworks paper filling equipment provided in the previous section. In one specific embodiment, this fireworks production line can be used to produce combination fireworks.

[0043] The fireworks paper filling equipment includes a frame 10, a punching mechanism 20, a first roller mechanism 30, a second roller mechanism 40, and a second drive device. The punching mechanism 20 is arranged on the frame 10 and is used to punch paper pieces from the paper strip 80 and push the paper pieces into the firing holes of the fireworks pyrotechnic 70. The first roller mechanism 30 and the second roller mechanism 40 are respectively arranged on both sides of the punching mechanism 20 to guide the paper strip 80 through the punching mechanism 20. The first roller mechanism 30 is arranged on the first side of the punching mechanism 20 and includes a first mounting frame 31, multiple first rollers 32, and a first drive device 33; the first rollers 32 and the first drive device 33 are mounted on the first mounting frame 31; the multiple first rollers 32 together clamp the paper strip 80. The second roller mechanism 40 is arranged on the second side of the punching mechanism 20, including a second mounting frame 41 and a plurality of second rollers 42; the second rollers 42 are mounted on the second mounting frame 41; the plurality of second rollers 42 together clamp the paper strip 80. The first driving device 33 is used to drive the first roller 32 to rotate, so as to pull the paper strip 80 from the second side of the punching mechanism 20 to the first side. The second driving device is used to drive the first roller mechanism 30 and the second roller mechanism 40 to offset perpendicular to the direction of movement of the paper strip 80 based on the initial position, or to return to the initial position. The first driving device and the second driving device can drive the paper strip to adjust its position, so that the punching mechanism 20 can punch multiple pieces of paper in the same area on the paper strip. The punching holes of the multiple paper pieces are staggered, which improves the utilization rate of the paper strip and reduces the cost.

[0044] It should be noted that, Figures 1-4 The punching holes on the paper tape are not shown in the image. Figure 5 and Figure 6 The image shows the punching holes formed after the punching mechanism punches the paper tape twice.
