[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] This utility model discloses an automated production equipment for polymer material modification and blending, such as... Figure 1-6 As shown, it includes an outer shell 1, a discharge pipe 3 with a valve is fixedly installed on the outer bottom surface of the outer shell 1, and a discharge cylinder 4 is fixedly installed on the outer bottom surface of the discharge pipe 3. By opening the valve of the discharge pipe 3, the polymer material mixed inside the outer shell 1 can enter the discharge cylinder 4 through the discharge pipe 3.

[0023] A preheating box 2 for preheating polymer materials is fixedly installed on the left side of the top surface of the outer shell 1. An exhaust fan 101 is fixedly installed on the left side of the outer surface of the outer shell 1. The exhaust fan 101 is powered by an external power source. After the exhaust fan 101 is powered on, the motor of the exhaust fan 101 drives the impeller to rotate at high speed. The blades of the impeller throw the air to the periphery, increasing its kinetic energy. A low-pressure area is formed in the central area of ​​the impeller because the air is thrown out. The external atmospheric pressure forces the air in, achieving the effect of air intake and exhaust.

[0024] A connecting pipe 102 is fixedly connected between the inlet of the exhaust fan 101 and the discharge cylinder 4, and a transmission pipe 103 is fixedly connected between the outlet of the exhaust fan 101 and the preheating box 2. When the valve of the discharge pipe 3 is opened, the polymer material mixed in the outer shell 1, along with the residual heat inside the outer shell 1, will enter the discharge cylinder 4. The exhaust fan 101 will run, causing the hot air in the discharge cylinder 4 to flow, so that the hot air is transmitted to the preheating box 2 through the connecting pipe 102 and the transmission pipe 103, preheating the polymer material to be mixed inside the preheating box 2, and effectively utilizing the residual heat.

[0025] The preheating box 2 has crushing rollers 201 rotatably connected to both the left and right sides inside. The two crushing rollers 201 are mirror images of each other. Multiple crushing teeth are fixedly installed on the outer surface of the two crushing rollers 201. When the polymer material is poured into the preheating box 2 through the opening on the top surface of the preheating box 2, the two crushing rollers 201 rotate and crush the large-sized polymer material. This effectively avoids uneven heating during processing due to the different particle sizes of various polymer materials.

[0026] A feed pipe 202 with a valve is fixedly installed on the bottom surface of the preheating box 2, and the feed pipe 202 is fixedly connected to the top surface of the outer shell 1. By opening the valve of the feed pipe 202, the crushed polymer material can be allowed to enter the interior of the outer shell 1 for processing through the feed pipe 202.

[0027] Two gears 2021 are rotatably connected to the rear side of the outer surface of the preheating box 2, and the two gears 2021 are fixedly connected to the two crushing rollers 201 respectively. Both ends of the two crushing rollers 201 are provided with rotating rods. The rotating rods at one end of the two crushing rollers 201 are rotatably connected to the inner wall of the preheating box 2, while the rotating rods at the other end extend to the outside of the preheating box. The two gears 2021 are fixedly connected to the two rotating rods extending to the outside of the preheating box 2 respectively.

[0028] When the two gears 2021 rotate, they will drive the two crushing rollers 201 to rotate. Since the two gears 2021 are meshed, when one gear 2021 rotates, it will drive the other gear 2021 to rotate in the opposite direction, thus causing the two crushing rollers 201 to rotate in opposite directions.

[0029] A second motor 2022 is fixedly installed on the rear side of the outer surface of the preheating box 2, and the output end of the second motor 2022 is fixedly connected to one of the gears 2021. The second motor 2022 is powered by an external power source. When the second motor 2022 runs, it will drive one of the gears 2021 to rotate. Due to the meshing of the two gears 2021, the two gears 2021 will drive the two crushing rollers 201 to rotate in opposite directions.

[0030] The discharge cylinder 4 is rotatably connected to a spiral shaft 403, and spiral blades 402 are fixedly installed on the outer surface of the spiral shaft 403. A first motor 401 is fixedly installed on one side of the outer surface of the discharge cylinder 4, and the output end of the first motor 401 is fixedly connected to the spiral shaft 403. When the first motor 401 is powered by an external power source, it will drive the spiral shaft 403 to rotate. A discharge hole 404 is opened on one side of the outer bottom surface of the discharge cylinder 4. The first motor 401 drives the spiral shaft 403 to rotate at a low speed. The rotating spiral shaft 403 will drive the spiral blades 402 to rotate. When the spiral blades 402 rotate, they come into contact with the inner wall of the discharge cylinder 4 and the polymer material, generating axial thrust. The material moves forward along the inner wall of the discharge cylinder 4 due to the push of the blades. Under the continuous push of the spiral blades 402, the polymer material moves along the spiral path to the discharge hole 404 to discharge the mixed polymer material.

[0031] A protective mesh 4021 is fixedly installed at one end of the connecting pipe 102 inside the discharge cylinder 4. The protective mesh 4021 is a metal mesh, which can effectively prevent polymer materials entering the discharge cylinder 4 from entering the connecting pipe 102.

[0032] A third motor 1022 is fixedly installed in the middle of the outer top surface of the outer shell 1, and a stirring rod 1021 is rotatably connected in the middle of the inner top surface of the outer shell 1. The output end of the third motor 1022 is fixedly connected to the stirring rod 1021. After the third motor 1022 is powered by an external power source, it can drive the stirring rod 1021 to rotate, and physically stir and mix the various polymer materials in the outer shell 1. A heating plate 1023 is fixedly installed on the inner wall of the outer shell 1. The heating plate 1023 is powered by an external power source. When the current passes through the high resistance material in the heating plate 1023, heat is generated to heat the various polymer materials in the outer shell 1. Combined with the rotation of the stirring rod 1021, the various polymer materials are uniformly mixed, improving the performance of the materials and achieving the effect of modified blending.

[0033] The working principle of this utility model is as follows: When the user pours various polymer materials into the preheating box 2 through the opening on the top surface of the preheating box 2, the two crushing rollers 201 rotate in opposite directions to crush the large-sized polymer materials. Then, the valve of the conveying pipe 202 is opened, and the crushed polymer materials can enter the outer shell 1 through the conveying pipe 202. After the heating plate 1023 is energized, the current will generate heat when it passes through the high resistance material in the heating plate 1023, so as to heat the various polymer materials in the outer shell 1. In conjunction with the third motor 1022 driving the stirring rod 1021 to rotate, the various materials can be mixed evenly. During the mixing process, the various polymer materials to be processed can be poured into the preheating box 2.

[0034] Then, opening the valve of the discharge pipe 3 will allow the mixed polymer material inside the outer shell 1, along with the residual heat inside the outer shell 1, to enter the discharge cylinder 4. The first motor 401 drives the spiral shaft 403 to rotate at a low speed. The rotating spiral shaft 403 will then drive the spiral blades 402 to rotate. Under the continuous push of the spiral blades 402, the polymer material moves along the spiral path to the discharge hole 404 to discharge the mixed polymer material. During this process, the exhaust fan 101 runs, causing the hot air inside the discharge cylinder 4 to flow, so that the hot air is transmitted to the preheating box 2 through the connecting pipe 102 and the transmission pipe 103 to preheat the polymer material to be mixed inside the preheating box 2.
