DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further Figures 1-5 describes the present utility model in detail.

[0018] Embodiment 1 of the utility model discloses a high-efficiency extruder for strip-shaped aluminum pigments.

[0019] Refer to Figure 1 、 Figure 2 、 Figure 4, A high-efficiency extruder for strip-shaped aluminum pigments, comprising a conveying cylinder 1. Inside the conveying cylinder 1, a twin-screw 2 is arranged and driven by a motor 3 at the end. A rotational speed sensor 4 is arranged at the output end of the motor 3. Stirring blades 5 are arranged around the outer sides of the twin-screw 2, and the pitch of the stirring blades 5 decreases from front to back, gradually increasing the extrusion pressure on the aluminum pigments. The use of the twin-screw 2 has a better stirring and extrusion ability for the aluminum pigments, and can fully mix and compact the aluminum pigments and the mixed additives; on one side of the conveying cylinder 1, a display platform 6 is installed. The rotational speed sensor 4 is communicatively connected to the display platform 6. The communicative connection is a way of transmitting information. After the strip-shaped aluminum pigments are discharged, by measuring the output at the output end of the motor 3 through the rotational speed sensor 4, the number of rotations of the twin-screw 2 inside the conveying cylinder 1 can be known, and an electrical signal is transmitted to the plc control unit inside the display platform 6, and feedback is carried out through the display platform 6 to initially obtain the output quantity of the strip-shaped aluminum pigments; an extrusion mechanism 7 is arranged at the output end of the conveying cylinder 1.

[0020] Refer to Figure 1 , Figure 3 , The extrusion mechanism 7 includes a housing 8. At the end of the housing 8, a mounting ring 9 is sleeved and fixed. Inside the mounting ring 9, a shaping plate 10 is clamped, and a strip-shaped opening 11 is opened at the middle position of the shaping plate 10. By removing the mounting ring 9 and clamping a shaping plate 10 with different sizes of strip-shaped openings 11 inside the mounting ring 9, the size of the extruded strip-shaped aluminum pigment block can be adjusted.

[0021] Refer to Figure 1 , Figure 2 , The conveying cylinder 1 includes a protective shell 12 and an inner shell 13. Along the axial direction at the top of the inner shell 13, a volatilization port 14 is opened and externally connected to a solvent cleaning tank 15. A resistance heating layer 16 is arranged between the protective shell 12 and the inner shell 13. In the working state, the temperature inside the conveying cylinder 1 is maintained between 60°C and 90°C to volatilize and recycle the organic solvent in the aluminum pigments; a temperature sensor 17 is arranged inside the protective shell 12. The temperature sensor 17 is communicatively connected to the display platform 6.

[0022] Refer to Figure 1 , Figure 2 , A filter mesh plate 18 is arranged at the position of the volatilization port 14. The filter mesh plate 18 only filters the solvent contained in the aluminum pigments, and the solvent volatilizes while the aluminum particles are enriched.

[0023] Embodiment 1 of the utility model: The implementation principle of an efficient extruder for strip-shaped aluminum pigments is as follows: The aluminum pigments that have been ball-milled, broken, and sieved are input into the conveying cylinder 1. The motor 3 drives the stirring blades 5 to extrude the aluminum pigments. The pitch of the stirring blades 5 decreases from front to back, enhancing the extrusion force on the aluminum pigments. The heating layer 16 inside the conveying cylinder 1 heats up to volatilize the organic solvents in the aluminum pigments and recover them into the solvent cleaning tank 15. The temperature sensor 17 measures the temperature and displays it through the display console 6. The aluminum pigments form strips through the shaping plate 10 of the extrusion mechanism 7 and are collected. The size of the strip-shaped opening 11 can be replaced to achieve adjustable sizes of the extruded strip-shaped aluminum pigment blocks.

[0024] Embodiment 2 of the utility model: On the basis of Embodiment 1 of the utility model, an efficient extruder for strip-shaped aluminum pigments is disclosed.

[0025] Referring to Figure 5 , the extrusion mechanism 7 includes a housing 8. At the end of the housing 8, there are two hydraulic sheets 19 arranged facing each other. The hydraulic sheets 19 are driven to feed by hydraulic rods 20, and the hydraulic rods 20 are externally connected to a hydraulic system. Compared with the structure of the shaping plate 10 in Embodiment 1 of the utility model where the strip-shaped opening 11 is provided, using the hydraulic rods 20 to adjust the distance between the hydraulic sheets 19 can further achieve adjustable sizes of the extruded strip-shaped aluminum pigment blocks. It is more convenient without having to remove the extrusion mechanism 7, but it increases the structural complexity.

[0026] The above are all preferred embodiments of the present utility model. The protection scope of the present utility model is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
