In addition, different types of papers, such as corrugated paper, cardboard paper, and oiled paper, are used to manufacture different types of firecrackers, such as flower tubes and fireworks, due to their special physical properties. Traditional firecracker paper uses waste paper as the main raw material, supplemented by artemisia annua bamboo, reeds, straws, etc., and adds cassava starch, flame retardants, waterproof agents, etc. to make the base material. Dyes include components such as eosin or magenta, alcohol, sucrose powder, phosphoric acid, and boiling water, which are used to color the firecracker paper.

[0025] The rotating assembly 10 includes a motor support base 1001 installed on the left side surface of the top of the operating table 1. A second motor 1002 is installed on the top surface of the motor support base 1001. A third runner 1003 is installed at the output end of the second motor 1002. One end of a belt 1004 is installed on the outer wall of the third runner 1003. The inner wall of the other end of the belt 1004 is installed with a fourth runner 1005. A driven rod 1006 is installed on the inner wall of the fourth runner 1005. One side of the outer wall of the driven rod 1006 is rotatably connected to a support rod 1007. A first threaded rod 1008 is installed on the inner wall of the driven rod 1006. A first handle 1009 is installed on the top surface of the first threaded rod 1008.

[0026] The support assembly 13 includes a second electric telescopic rod 1301 installed on the top surface of the operating table 1.

[0027] In this embodiment, as Figure 1 shown, there are six hydraulic push rods 2 in total, and the hydraulic push rods 2 and the operating table 1 form a lifting mechanism; through this design, the height of the operating table 1 can be adjusted by starting the hydraulic push rods 2 as needed, so that the device has the function of adjustable height.

[0028] In this embodiment, as Figure 2 shown, the first motor 4 and the second runner 8 form a transmission mechanism through the first runner 5 and the conveyor belt 7, and an anti-slip pad is provided on the surface of the conveyor belt 7; through this design, the firecracker paper can be placed on the surface of the conveyor belt 7, and then the first motor 4 is started. While the first motor 4 drives the first runner 5 to rotate, the second runner 8 is driven to rotate through the conveyor belt 7, so as to realize the conveying of the firecracker paper and prevent the firecracker paper from shifting during winding, affecting the winding of the firecracker paper.

[0029] In this embodiment, as Figure 4 shown, the second motor 1002 and the fourth runner 1005 form a transmission mechanism through the third runner 1003 and the belt 1004; through this transmission mechanism, the second motor 1002 can be started. While the second motor 1002 drives the third runner 1003 to rotate, the fourth runner 1005 is driven to rotate through the belt 1004. Since one end of the roller 11 is connected to the driven rod 1006, the roller 11 can be driven to rotate, thereby realizing the winding function of the firecracker paper.

[0030] In this embodiment, as Figure 3 shown, one end of the roller 11 is provided with a plug, and one end of the driven rod 1006 is provided with a slot whose internal dimension structure is consistent with the external dimension structure of the plug. Moreover, the surface of the plug is provided with a first mounting hole whose internal dimension structure is consistent with the external dimension structure of the first threaded rod 1008. Through this design, one end of the roller 11 can be plugged and installed with the driven rod 1006 through the plug and the slot. At this time, the first mounting hole is located directly below the first threaded rod 1008. The first handle 1009 can be rotated to drive the first threaded rod 1008 to move downward, so that the first threaded rod 1008 is inserted into the first mounting hole, and the roller 11 and the driven rod 1006 can be quickly fixed. Conversely, the roller 11 and the driven rod 1006 can be quickly disassembled, which is convenient for the maintenance and replacement of the roller 11.

[0031] In this embodiment, as Figure 5 shown, the second electric telescopic rod 1301 and the main clamp 1302 form a telescopic mechanism, and the sub-clamp 1307 forms a rotating mechanism with the main clamp 1302 through the hinge 1306. Moreover, one side surface of the sub-fixed block 1308 is provided with a second mounting hole whose internal dimension structure is consistent with the external dimension structure of the second threaded rod 1304. Through this design, when the user needs to disassemble the roller 11, the second handle 1305 can be rotated to drive the second threaded rod 1304 to move to one side, so that the second threaded rod 1304 is pulled out of the second mounting hole. Then, the sub-clamp 1307 can be rotated and opened with the main clamp 1302 through the hinge 1306. Next, the second electric telescopic rod 1301 is started, and the second electric telescopic rod 1301 lowers the main clamp 1302 as a whole to an appropriate height, and then the roller 11 can be horizontally pulled out.

[0032] In this embodiment, as Figure 1 shown, the first electric telescopic rod 15 and the second limiting rod 18 form a lifting mechanism through the mounting block 17. Through this design, the first electric telescopic rod 15 can be started as needed. The first electric telescopic rod 15 adjusts the height of the second limiting rod 18 through the mounting block 17, and the distance between the second limiting rod 18 and the first limiting rod 16 can be adjusted according to the thickness requirement of the firecracker paper, which is convenient for limiting the firecracker paper in the vertical direction and avoiding the deviation of the firecracker paper during the winding process, affecting the winding quality.

[0033] The usage method and advantages of the present utility model: For this winding device facilitating the installation and disassembly of the roller, during use, the working process is as follows:

[0034] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, first start the hydraulic push rod 2 to adjust the height of the operating table 1. Then place the firecracker paper on the surface of the conveyor belt 7, pass one end of the firecracker paper through the space between the second limiting rod 18 and the first limiting rod 16, and then place the firecracker paper on the outer wall of the roller 11. Then start the first electric telescopic rod 15. The first electric telescopic rod 15 adjusts the height of the second limiting rod 18 through the mounting block 17. The distance between the second limiting rod 18 and the first limiting rod 16 can be adjusted according to the thickness requirement of the firecracker paper, which is convenient for limiting the firecracker paper in the vertical direction. Then start the first motor 4. While the first motor 4 drives the first runner 5 to rotate, it drives the second runner 8 to rotate through the conveyor belt 7 to realize the conveyance of the firecracker paper. At the same time, start the second motor 1002. While the second motor 1002 drives the third runner 1003 to rotate, it drives the fourth runner 1005 to rotate through the belt 1004. Since one end of the roller 11 is connected to the driven rod 1006, the roller 11 can be driven to rotate to wind up the firecracker paper. If it is necessary to disassemble the roller 11, rotate the first handle 1009 to drive the first threaded rod 1008 to move downward, so that the first threaded rod 1008 is pulled out from the first mounting hole to release the fixation between the roller 11 and the driven rod 1006. Then rotate the second handle 1305 to drive the second threaded rod 1304 to move to one side, so that the second threaded rod 1304 is pulled out from the second mounting hole. Then rotate the auxiliary clamp 1307 to open it with the main clamp 1302 through the hinge 1306. Then start the second electric telescopic rod 1301. While the second electric telescopic rod 1301 lowers the whole main clamp 1302, the roller 11 can be horizontally pulled out.

[0035] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments.
