Description

Technical Field

[0001] This utility model relates to the field of fireworks processing technology, and in particular to a paper tube extrusion molding machine. Background Technology

[0002] Paper tube extrusion molding machines are key equipment in the fireworks and firecrackers industry for producing paper tubes for fireworks. Technological advancements reflect the industry's continuous pursuit of safe production, efficiency improvement, and environmental protection. The fireworks and firecrackers industry has long relied on manual paper tube production, involving multiple processes such as paper cutting, rolling, gluing, and drying. Manual production suffers from low efficiency, unstable quality, and significant safety hazards. Especially in the paper cutting and rolling stages, improper operation can easily lead to uneven paper tube wall thickness and insufficient strength, affecting the safety of fireworks displays. With the development of industrial automation technology, the fireworks and firecrackers industry has gradually introduced mechanical equipment to replace manual operations. Paper tube extrusion molding machines, through mechanical extrusion and mold forming, achieve standardized production of paper tubes, significantly improving production efficiency and product quality.

[0003] To meet the production needs of different specifications of firework paper tubes, the equipment will adopt a modular design, which facilitates quick mold changes and parameter adjustments. The multi-functional equipment can also realize integrated processing of paper tube cutting and punching, reducing production links. Combined with the paper tube extrusion molding machine, energy utilization efficiency will be further optimized by using low-energy motors and environmentally friendly adhesives. At the same time, the equipment will enhance waste recycling functions to achieve green production processes. However, the traditional product performance optimization is poor. Secondly, the dense structure makes the compressive strength and wall thickness uniformity of the paper tube low. In addition, the stacking stability of irregular cross-sections is poor, and the cut surface is not neat enough, which easily leads to burrs. Therefore, it cannot meet the sealing requirements of firework tube filling. Utility Model Content

A forming mechanism 4 is arranged on the right side of the extrusion mechanism 2. The forming mechanism 4 can change the size and shape of the mold according to requirements. The table 10... A heating mechanism 5 is provided on the right side of the top center. The heating mechanism 5 is an adjustable high-frequency heating device, which can flexibly set the heating and baking position to facilitate faster drying of the product. A cooling mechanism 6 is provided on the right side of the heating mechanism 5.

[0031] Specifically, the feeding mechanism 9 assists in the smoother entry of materials into the extrusion space throughout the entire processing flow.

[0032] Please see the appendix Figure 2 - Appendix Figure 4The transmission mechanism 3 includes an L-shaped plate 16. The top of the L-shaped plate 16 is fixedly connected to the bottom left side of the table 10. A servo motor 13 is fixedly connected to the middle left side of the L-shaped plate 16. The output end of the servo motor 13 passes through one side of the L-shaped plate 16 and is fixedly connected to the corresponding pulley 15.

The outer walls of the two pulleys 31 are connected by a transmission belt 33. A movable plate 26 is provided on the top of the transmission belt 33. A fixed plate 27 is fixedly connected to the middle of the top of the movable plate 26. Servo motor 25 is fixedly connected to the upper right side of plate 27. The output end of servo motor 25 passes through the right side of plate 27 and is fixedly connected to cutting head 24. Extrusion mechanism 2 includes spiral extrusion rod 18. The left and right ends of spiral extrusion rod 18 are rotatably connected to the inner side of extrusion mechanism 2. The left end of spiral extrusion rod 18 is fixedly connected to the corresponding pulley 15. The left side of the upper pulley 15 is rotatably connected to L-shaped plate 14. The bottom of L-shaped plate 14 is fixedly connected to the top left side of table 10.

[0035] Specifically, the movable plate 26 acts as a flexible moving platform, moving smoothly with the operation of the transmission belt 33. The top center of the movable plate 26 is firmly connected to the fixed plate 27, and the cutting head 24 is securely fixed. When the servo motor 25 starts running, the cutting head 24, with its sharp blade and powerful rotational force, can perform precise cutting operations on the material, allowing the spiral extrusion rod 18 to rotate flexibly inside the extrusion mechanism 2. The left end of the spiral extrusion rod 18 is fixedly connected to the corresponding pulley 15, ensuring that the pulley 15 can operate smoothly, thereby ensuring the normal operation of the spiral extrusion rod 18, making the entire extrusion and cutting process efficient.

[0036] Please see the appendix Figure 1 - Appendix Figure 3 The traction mechanism 7 includes a connecting plate 28. The left end of the connecting plate 28 is fixedly connected to the right side of the table 10. A servo motor 29 is fixedly connected to the front left side of the connecting plate 28.

The feeding mechanism 9 includes a feeding hopper 1. The top end of the feeding mechanism 9 is connected to the feeding hopper 1. The bottom end of the feeding mechanism 9 is located on the top left side of the extrusion mechanism 2.

[0037] Specifically, the connecting plate 28 serves as the connection and support plate, and a servo motor 29 is fixedly installed at its left front end. The power of the servo motor 29 is fixedly connected to the threaded rod 30 at its output end. When the servo motor 29 starts running, its output end will drive the threaded rod 30 to rotate. The feeding hopper 1 is located at the top of the feeding mechanism 9 and is connected to the feeding mechanism 9. The feeding hopper 1 is usually funnel-shaped, which makes it easy for operators to quickly and conveniently put various materials into it, ensuring that the materials can smoothly enter the interior of the feeding mechanism 9 from the feeding hopper 1.

[0038] Working principle: First, the raw material enters the feed hopper 1 through the screw extrusion rod 18, which pushes the material forward. Simultaneously, the external heating of the barrel and the frictional heat of the screw extrusion rod 18 work together to melt and plasticize the material. As the material enters the compression section, the screw groove depth gradually decreases, further compacting and expelling air bubbles to form a uniform melt. The extruded molten material is then homogenized in a temperature and pressure control section before being formed through a mold. The mold's inner wall design directly affects the surface finish of the pipe. Combined with the extrusion mechanism 2, this ensures density. Then, with the cooling mechanism 6, the formed pipe enters the air-cooling system, where the fan 22 and heat dissipation holes 21 enhance cooling. The cooling rate prevents deformation and improves mechanical strength. Then, the tube is synchronously transported to the cutting position by the cutting mechanism 8 and the traction mechanism 7. With the help of the servo motor 25 and the cutting head 24, the tube is automatically cut according to the preset length, which can adapt to different production rhythm requirements. Therefore, the production efficiency is improved and the whole process is continuous. Compared with the traditional winding process, the efficiency is significantly improved. Secondly, the product performance is optimized. The dense structure increases the compressive strength of the paper tube and the wall thickness uniformity is better than the manual winding process. At the same time, the irregular cross-section design enhances the stacking stability and ensures the cutting accuracy. The cut surface is flat and burr-free, which meets the sealing requirements of the fireworks tube filling.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
