Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-7 , the present invention provides a technical solution: a micro-formula debugging instrument, including: a barrel support 1 and an electrical box 12. A cylinder assembly 3 is arranged on the back of the barrel support 1. The telescopic end of the cylinder assembly 3 is fixedly connected to a cylinder connecting piece 5. The cylinder connecting piece 5 is fixedly connected to a heavy-duty linear guide rail 4. The heavy-duty linear guide rail 4 is linearly slidably connected to the barrel support 1 in the up and down direction. The upper end of the heavy-duty linear guide rail 4 is fixedly installed with a piston connecting piece 6. The piston connecting piece 6 is fixedly installed with a push rod 7. The push rod 7 movably penetrates through the locking nut 2, and the locking nut 2 plays a guiding role;

[0032] The upper end of the push rod 7 is fixedly connected to the piston connecting piece 6 through a hexagon socket head bolt 8. The push rod 7 is inserted into the barrel 13. The first mixing chamber 15, the second mixing chamber 16 and the die head 17 are detachably installed at the lower end of the barrel 13 in sequence. The push rod 7 presses the raw materials downward in the barrel 13. After being mixed in the first mixing chamber 15 and the second mixing chamber 16, they are extruded from the die head 17.

[0033] The second mixing chamber 16 is provided with mixing elements, and the mixing elements include but are not limited to ball combinations.

[0034] The first mixing chamber 15 is provided with a number of inclined holes, the upper openings of which are large and the lower openings are small.

[0035] The cross-section of the discharge end of the die head 17 is rectangular or circular and can be replaced according to requirements.

[0036] A heating coil 14 is sleeved on the outer surface of the barrel 13. The heating coil 14 heats the barrel 13, and then heats the material to soften the material for easy shaping.

[0037] A motor 11 is installed on the inner wall of the barrel support 1. A scraper assembly 18 is installed on the output shaft of the motor 11. The scraper assembly 18 is located directly below the discharge port die 17. After the material is extruded from the discharge port die 17, the motor 11 drives the scraper assembly 18 to rotate, and repeatedly cuts the extruded material into particles.

[0038] The motor 11 is fixedly installed on the inner wall of the barrel support 1 in an embedded manner through a motor connection block 9. The front end of the motor connection block 9 is fixedly installed with a motor connection member 10. The motor connection member 10 is plate-shaped and blocks between the scraper assembly 18 and the motor 11 to prevent the material from being thrown onto the motor 11 during granulation.

[0039] An electrical box 12 is provided on one side of the barrel support 1. The electrical box 12 is provided with an intelligent temperature controller 123, a push rod down button 124, a power switch 125, a push rod up button 126, and a pulse speed regulator 128.

[0040] Working principle: The expansion and contraction of the cylinder assembly 3 and the rotation of the motor 11 are controlled through the electrical box 12. The expansion and contraction of the cylinder assembly 3 drives the push rod 7 to lift and lower. The push rod 7 rises and disengages from the barrel 13, and raw materials and auxiliary materials are added into the barrel 13. After being heated and melted by the heating coil 14, the push rod 7 descends, and the material in the barrel 13 is extruded and mixed through the first mixing chamber 15 and the second mixing chamber 16, and then discharged through the discharge port die 17. The motor 11 drives the scraper assembly 18 to repeatedly cut the extruded material into particles. Only three steps of raw material and auxiliary material blending, instrument mixing and extrusion, and sampling and testing are required, reducing the consumption of raw materials and auxiliary materials in the formulation test, reducing the time of the formulation test, greatly improving the test efficiency, and at the same time reducing energy consumption and manual operation. The overall volume is small and the applicable range is wide.

[0043] The comparison data of the present invention with the traditional technical solution in adjusting the flame retardancy formula of PVC cable materials is shown in the following table:

[0044]

[0045] In summary, compared with the traditional technical solution, the technical solution of the present application saves the vast majority of raw materials, energy consumption and man-hours, and the cost savings are more than 90%.
