Description

Technical Field

[0002] With the rapid development of the e-commerce industry, the demand for express delivery bags, as the core material of logistics packaging, continues to rise. The production of express delivery bags mainly uses polyethylene and polypropylene plastic raw materials, which need to be made by adding antioxidants, toughening agents and opening agents, and then through mixing, plasticizing and blown film processes. Among them, the uniform mixing of raw materials directly affects the physical properties of plastic film, such as strength, flexibility, puncture resistance and the stability of the production process. However, there are many technical bottlenecks in plastic raw material mixing and stirring equipment, and technological upgrades are urgently needed to meet the needs of efficient and high-quality production.

[0003] In addition, the environmental protection requirements for express delivery bag production are becoming increasingly stringent, and the application of biodegradable plastics is gradually becoming more widespread. However, traditional mixing devices are difficult to adapt to the sensitive characteristics of these materials to temperature and shear force. Excessive mixing intensity may cause the molecular chains of biodegradable plastics to break down, reducing the mechanical properties of the product. Therefore, existing plastic raw material mixing and stirring devices lack strong shear force during the mixing process, resulting in rapid breakage of agglomerated plastic raw materials, increasing mixing time, reducing mixing effect, and thus failing to meet mixing requirements. Summary of the Invention

When the servo motor 13 drives one of the sprockets 14 to rotate, the other sprocket 14 will also rotate through the transmission action of the chain belt 20.

[0034] Please see the appendix Figure 1 - Appendix Figure 3 The cleaning mechanism 2 includes a U-shaped frame 201. The bottom right side of the U-shaped frame 201 is fixedly connected to the middle left side of the support 1. A water tank 202 is fixedly connected to the top right side of the U-shaped frame 201. A material box 203 is fixedly connected to the top left side of the water tank 202. An L-shaped pipe 204 is connected to the right side of the material box 203.

[0035] Specifically, the U-shaped frame 201 maintains sufficient stability and reliability under various external forces. A material box 203 is fixedly connected to the top left side of the water tank 202. To the right of the material box 203, an L-shaped pipe 204 is connected via piping technology. This ingeniously designed L-shaped pipe 204 ensures smooth flow of material from the material box 203 into the water tank 202 and is connected to a telescopic pipe 207. This telescopic pipe 207 has excellent telescopic performance, allowing its length and angle to be adjusted according to actual needs, thus conveniently transporting the liquid in the water tank 202 to a designated location.

[0036] Please see the appendix Figure 1 - Appendix Figure 3The top of the material box 203 is connected to a hollow plate 211, and the top of the hollow plate 211 is engaged with a baffle 212. The outer wall of the L-shaped tube 204 is connected to a second electromagnetic valve 210. The middle of the outer wall of the telescopic tube 207 is connected to a first electromagnetic valve 208.

The telescopic tube 207 connects the water tank 202 to the subsequent transportation links, and its outer wall is also connected to the first solenoid valve 208. The locking groove at the bottom of the inner side of the discharge plate 7 fits tightly to ensure that the baffle 5 is stable and reliable in the locking state and is not easy to loosen.

[0038] Working principle: When it is necessary to mix plastic raw materials, the raw materials are first put into the inner side of the mixing tank 6. At this time, the servo motor 13 connected to the L-shaped plate 10 is started, which drives the sprocket 14 to rotate the rotating rod 17 in conjunction with the chain belt 20. The rotating rod 17 mixes and stirs the plastic raw materials inside for the first time. Then, the servo motor 12 connected to the triangular plate 11 is turned on, which drives the rotating rod 18 to rotate in the opposite direction. The turbine blade 19, the pentagonal blade 15, and the turbine blade 21 rotate simultaneously, which generates a strong shearing force to quickly break up the clumps of plastic raw materials, reduce the mixing time, and improve the mixing effect.

[0039] Afterwards, the second solenoid valve 210 is opened, and the cleaning material inside the material box 203 is transported to the inside of the water tank 202 through the L-shaped pipe 204, so as to mix with the water source inside the water tank 202. Then, one end is fixed to the U-shaped frame 201 to achieve a stabilizing effect. Finally, the first solenoid valve 208 is activated, and the telescopic pipe 207 is used to transport the water source to the inside of the mixing tank 6 for stirring and cleaning. Therefore, the inside of the mixing tank 6 can be cleaned in time after stirring, which is convenient for operators to use the equipment later and improves convenience.

[0040] 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.
