DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 2 As shown, a plastic powder extruder for plastic powder production comprises: a base 1, an extruder body 2 is arranged on one side of the base 1, a transmission component 3 is arranged on one side of the top of the extruder body 2, a material transfer component 4 is arranged in the middle of the top of the extruder body 2, a screw barrel 7 is arranged on the inner side of the material transfer component 4, and auxiliary structures 8 are arranged on both sides of the screw barrel 7;

[0028] A stirring tank 5 is arranged at the top of the material transfer component 4 , a stirring rod 6 is arranged inside the stirring tank 5 , and a stirring structure 9 is arranged at the bottom end of the stirring rod 6 .

[0029] like Figure 1-Figure 7As shown, a plastic powder extruder for plastic powder production, the auxiliary structure 8 includes an auxiliary rod 801, a first screw groove 802 and a second screw groove 803, the auxiliary rods 801 are arranged on both sides of the screw barrel 7, the first screw groove 802 is arranged on the outer side of the auxiliary rod 801, the second screw groove 803 is arranged on one side of the first screw groove 802, the number of spiral layers of the second screw groove 803 is equal to the number of spiral layers of the first screw groove 802, the material is conducted by the screw barrel 7, when the gap of the thread profile on the outer side of the screw barrel 7 is too large, the auxiliary rod 801 replaces the position of the screw barrel 7, and the double-layer structure of the first screw groove 802 and the second screw groove 803 on the outer side of the auxiliary rod 801 can replace the material conduction and ensure the adequacy of the material conduction:

[0030] This brings several key effects and advantages:

[0031] Enhanced material transmission efficiency: When the thread profile gap on the outside of the screw barrel 7 is too large, the auxiliary rod 801 can be replaced to the position of the screw barrel 7, and the double-layer structure formed by the first screw groove 802 and the second screw groove 803 on the outside can effectively replace the material conduction function. This double-layer spiral structure design increases the material contact area and improves the material transmission efficiency.

[0032] Improve the uniformity of material mixing: The number of spiral layers of the first screw groove 802 and the second screw groove 803 is equal, which ensures that the flow speed and pressure distribution of the material in the two screw grooves are consistent, which helps to mix the material uniformly during the extrusion process, thereby improving the quality of the final product.

[0033] Improve equipment adaptability and flexibility: Since the auxiliary rod 801 can be quickly replaced when the screw barrel 7 has problems or needs to be replaced, this design improves the adaptability and flexibility of the equipment. It allows local maintenance or adjustments without stopping the entire production line, reducing the risk of production interruption.

[0034] Reduced material waste and production costs: By ensuring sufficient material conduction, the auxiliary structure 8 reduces waste caused by insufficient material transmission. At the same time, since the auxiliary rod 801 can be quickly replaced, downtime is reduced, which indirectly reduces production costs.

[0035] Prolong the service life of the equipment: The design of the auxiliary rod 801 can reduce the workload of the screw barrel 7, especially when the screw barrel 7 is worn or damaged, the auxiliary rod 801 can be used as a temporary or long-term substitute, thereby extending the service life of the entire extruder. The design of the auxiliary structure 8 not only improves the material transmission efficiency and product quality of the equipment, but also enhances the adaptability and flexibility of the equipment, reduces production costs and material waste, and prolongs the service life of the equipment. These effects work together to improve the performance and benefits of the entire extrusion process.

[0036] like Figure 1-Figure 7As shown, a plastic powder extruder for plastic powder production, the stirring structure 9 includes a clamping plate 901, a first steering rod 902 and a second steering rod 903, the bottom end of the stirring rod 6 is provided with a clamping plate 901, the bottom end of the clamping plate 901 is provided with a first steering rod 902, one end of the first steering rod 902 is provided with a second steering rod 903, the clamping plate 901 and the stirring rod 6 are fixedly connected, the stirring rod 6 drives the clamping plate 901 to rotate, the clamping plate 901 drives the first steering rod 902 and the second steering rod 903 to rotate, the staff can adjust the position of the second steering rod 903 and the first steering rod 902, so that the plane shape formed when the first steering rod 902 and the second steering rod 903 rotate is changed, thereby increasing the mixing degree of the material:

[0037] This brings the following significant effects and advantages:

[0038] Improve material mixing effect: By adjusting the positions of the second steering rod 903 and the first steering rod 902, the plane shape formed when they rotate can be changed, thereby affecting the flow path and mixing mode of the material during the extrusion process. This adjustable mixing mechanism can significantly improve the mixing degree of the material and ensure that the various components are evenly distributed, which is crucial for producing high-quality plastic products.

[0039] Enhanced stirring flexibility: The adjustable nature of the stirring structure 9 gives the operator the ability to adjust the stirring effect according to different production requirements. This flexibility enables the extruder body 2 to adapt to different formulas and types of plastic raw materials, expanding the application range of the machine.

[0040] Optimize energy consumption and production efficiency: Since the stirring structure 9 can be adjusted according to actual needs, it can use energy more effectively and avoid unnecessary energy waste. At the same time, better mixing effect means less waste rate and higher production efficiency.

[0041] Improve product quality: Uniform material mixing is one of the key factors in producing high-quality plastic products. The optimized design of the stirring structure 9 helps to eliminate unmelted particles and uneven areas in the material, thereby improving the quality and performance of the final product.

[0042] Simplified operation and maintenance: Although the stirring structure 9 provides advanced mixing functions, its design remains simple, which is convenient for operators to adjust positions and perform routine maintenance. The intuitiveness and ease of use of this design help reduce operating errors and maintenance costs. The design of the stirring structure 9 significantly improves the material mixing effect and production flexibility of the equipment by providing an adjustable mixing mechanism, while optimizing energy consumption and production efficiency, improving product quality, and simplifying the operation and maintenance process. These effects together promote the overall performance and benefits of the extrusion process.

[0043] Working principle: When using the plastic powder extruder for plastic powder production, first connect the external power supply, then the transmission component 3 and the extruder body 2 start to work, the inside of the stirring tank 5 receives the material, and the stirring rod 6 stirs the inside of the stirring tank 5. When the stirring rod 6 rotates, the stirring rod 6 drives the clamping plate 901 to rotate, and the clamping plate 901 drives the first steering rod 902 and the second steering rod 903 to rotate. The staff can adjust the position of the second steering rod 903 and the first steering rod 902 so that the first steering rod 902 and the second steering rod The plane shape formed when 903 rotates changes, thereby increasing the mixing degree of the material. After the material enters the interior of the material transfer component 4, the screw barrel 7 rotates on the inner side of the material transfer component 4. At this time, the material is conducted by the screw barrel 7. When the gap of the thread profile on the outer side of the screw barrel 7 is too large, the auxiliary rod 801 replaces the position of the screw barrel 7. At the same time, the double-layer structure of the first screw groove 802 and the second screw groove 803 on the outer side of the auxiliary rod 801 can replace the material conduction and ensure the adequacy of the material conduction. This is the working principle of the plastic powder extruder for plastic powder production.
