Description
Technical Field
[0001] This utility model belongs to the field of plastic production technology, and in particular relates to an engineering plastic mixing device. Background Technology
[0002] Engineering plastics refer to industrial plastics used as materials for industrial parts or housings. They have superior strength, impact resistance, heat resistance, hardness, and aging resistance compared to general-purpose plastics. In Japan, the industry defines them as high-performance plastics with heat resistance above 100°C, suitable for structural and mechanical parts.
[0003] In the production process, mixing is a crucial step that directly affects the quality and performance of the final product. Traditional mixing devices can only subject the materials to limited stirring, and the materials inside the mixing tank are prone to agglomeration, resulting in an insufficiently fine and uniform mixing effect. This not only prolongs the mixing time but also reduces production efficiency. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0027] Example 1
[0028] This utility model provides an engineering plastic mixing device, such as... Figures 1 to 5 As shown, the engineering plastic mixing device includes a mixing tank 1, a mounting frame 2, and a mixing assembly. The mixing tank 1 is used to store plastic granules, and the mounting frame 2 is used to support and fix the mixing tank 1. The mixing assembly includes a drive component 3, a main rotating rod 4, a drive gear 5, a propeller blade 6, a secondary rotating rod 7, a driven gear 8, and a mixing blade 9. The drive component 3 is fixedly installed at the bottom of the mixing tank 1. The main rotating rod 4 is connected to the drive component 3 and installed inside the mixing tank 1. The drive gear 5 is fixedly sleeved on the outer surface of the main rotating rod 4. The propeller... The blade 6 is installed on the main rotating rod 4. There are two sets of auxiliary rotating rods 7, which are symmetrically distributed about the main rotating rod 4. The tops of the two auxiliary rotating rods 7 and the main rotating rod 4 are rotatably installed on the top cover of the mixing tank 1. The outer surfaces of the two auxiliary rotating rods 7 are fixedly sleeved with driven gears 8. The two sets of driven gears 8 and the driving gear 5 are installed at the same height inside the mixing tank 1. Each set of auxiliary rotating rods 7 is fixedly installed with stirring blades 9. The multiple stirring blades 9 installed on each auxiliary rotating rod 7 are arranged in an equidistant staggered pattern.
[0029] In this embodiment, the heating component of the engineering plastic mixing device includes a fan 10, an air inlet pipe 11, and a valve 12. The fan 10 is fixedly installed on the top cover of the mixing tank 1. The air inlet pipe 11 is connected to the air outlet of the fan 10. The two auxiliary rotating rods 7 are hollow inside, and each stirring blade 9 has a valve 12 installed inside.
[0030] By rotating the main rotating rod 4, the symmetrically arranged auxiliary rotating rod 7 is driven to rotate, thereby causing the propeller blade 6 and the stirring blade 9 to rotate synchronously inside the mixing tank 1. This causes the material inside the mixing tank 1 to be subjected to multi-dimensional stirring forces, thereby improving the mixing uniformity of the plastic granules in the mixing tank 1.
[0031] During use, the operator powers on the drive unit 3, causing the main rotating rod 4 to rotate inside the mixing tank 1. The rotation of the main rotating rod 4, through the connection of the drive gear 5, drives two sets of driven gears 8 to rotate synchronously. This ensures that when the drive unit 3 is working, both the main rotating rod 4 and the two sets of auxiliary rotating rods 7 rotate in the same direction but opposite to the direction of the main rotating rod 4. This allows the propeller blades 6 and the stirring blades 9 to stir the mixture inside the mixing tank 1, resulting in a more comprehensive and intense stirring force on the plastic granules, achieving a more uniform mixing effect. Simultaneously, the stirring blades 9 activate the fan 10, which delivers hot air through the air inlet pipe 11 to the interior of the auxiliary rotating rods 7. The hot air inside the auxiliary rotating rods 7 is then discharged through the stirring blades 9, allowing the stirring blades 9 to dry the plastic material while stirring, preventing excessive moisture from causing sticking during mixing.
[0032] A partition plate 17 is also fixedly installed on the inner wall of the mixing tank 1. The bottom ends of the two sets of auxiliary rotating rods 7 are rotatably connected to the partition plate 17, ensuring that both ends of the auxiliary rotating rods 7 are stably supported, making the auxiliary rotating rods 7 more stable during rotation. The partition plate 17 can block the plastic material directly above it, preventing the material from falling into the drive component 3 below, thus ensuring that the drive component 3 can operate normally and preventing the material from getting stuck in the drive component 3 and causing damage. Moreover, the partition plate 17 and the discharge pipe 13 are set at the same height, ensuring that the material after being mixed evenly in the mixing tank 1 can be smoothly discharged through the discharge pipe 13, avoiding the problem of material accumulation and discharge difficulties caused by the inconsistent height of the partition plate 17 and the discharge pipe 13.
[0033] In order for the uniformly mixed plastic granules to be smoothly discharged along the discharge pipe 13, such as Figures 1 to 5 As shown, a valve 14 is installed on the discharge pipe 13. Specifically, the valve 14 can be set as an electric valve 14. The valve 14 can be precisely controlled to open and close by an electrical signal. Compared with manual operation, the operation of the electric valve 14 is faster and simpler, reducing the time and labor intensity of manual operation. A drive component 15 is fixedly installed on the outer surface of the discharge pipe 13. A feeding paddle 16 is rotatably connected inside the discharge pipe 13. The feeding paddle 16 is connected to the output shaft of the drive component 15.
[0034] When the plastic granules in the mixing tank 1 are being mixed, the valve 14 is closed by an electrical signal to prevent the material from being exposed along the discharge pipe 13. After the plastic material in the mixing tank 1 is mixed evenly, the valve 14 is opened and the drive component 15 is energized. When the drive component 15 is working, it can drive the feeding paddle 16 to rotate inside the discharge pipe 13, thereby breaking up and discharging the material blocked at the location of the discharge pipe 13, improving the discharge efficiency.
[0035] Specifically, both drive component 3 and drive component 15 are motors. The main rotating rod 4 is connected to the output shaft of drive component 3 via a flat key, and the feeding blade 16 is connected to the output shaft of drive component 15 via a flat key. The fan 10 is an existing device with an internal heating wire. When the heating wire is energized, it generates heat. When the cold air passes through the heating wire, it exchanges heat with the cold air, thereby raising the air temperature and discharging it.
[0036] Working principle: In actual use, the staff first closes valve 14 to block the outlet of discharge pipe 13, and then fills the plastic granules into the mixing tank 1 through the inlet set on the top cover of the mixing tank 1. After all the raw materials of the mixed plastic in the mixing tank 1 have been added, the next step of stirring and mixing operation begins.
[0037] Turn on the switch of the control drive component 3 and power it on to drive the main rotating rod 4 to rotate. The rotation of the main rotating rod 4 drives the two sets of symmetrically arranged driven gears 8 to rotate synchronously through the connection of the drive gear 5. The rotation direction of the two sets of driven gears 8 is opposite to the rotation direction of the drive gear 5, so that the main rotating rod 4 and the two sets of auxiliary rotating rods 7 can rotate synchronously inside the mixing tank 1, realizing the mixing operation of the propeller blade 6 and the stirring blade 9 inside the mixing tank 1. Through the staggered arrangement of the stirring blades 9, the plastic particles in the mixing tank 1 can be subjected to multi-dimensional stirring force, achieving a more uniform mixing effect.
[0038] While the stirring blades 9 are stirring, the fan 10 installed on the top cover of the mixing tank 1 works and delivers the generated hot air through the air inlet pipe 11 to the interior of the auxiliary rotating rod 7. The hot air delivered inside the auxiliary rotating rod 7 breaks through the valve 12 and is discharged into the interior of the mixing tank 1, thereby drying the material in the mixing tank 1 and realizing the integrated operation of mixing and drying, avoiding the phenomenon of sticking during stirring due to excessive moisture in the material.
[0039] When the material in the mixing tank 1 is finished mixing and needs to be discharged, open valve 14 to open the outlet of discharge pipe 13, and energize drive component 2 15 to drive the feeding paddle 16 to rotate. When the feeding paddle 16 rotates, it can disperse the material blocked at the outlet of discharge pipe 13, so as to avoid excessive material accumulation at the outlet of discharge pipe 13 and affect the normal discharge of material.
[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
