Description
Technical Field
[0001] This utility model relates to the field of PP material mixers, and in particular to a mixer for the production of weather-resistant PP materials. Background Technology
[0002] Weather-resistant PP is a specially modified PP material designed to significantly improve its durability for outdoor use. This is achieved through various processing techniques, including filling, blending, reinforcement, flame retardancy, and weather resistance enhancements, on these plastic particles.
[0003] Chinese patent discloses a vertical mixer for PP material production, application number 202222232662.4. This patent mainly includes a mixing tank, a mixing shaft, fan blades, and a sleeve. One end of the mixing shaft is located inside the sleeve, and the fan blades are fixedly connected between the sleeve and the mixing shaft. The outer side of the sleeve is fixedly connected to the mixing blades. A funnel-shaped inlet is fixedly connected to the upper part of the mixing tank, and a support frame is fixedly connected inside the inlet. The upper end of the mixing shaft is rotatably connected to the horizontal part of the upper part of the support frame. Although this patent uses a gear driven by a second motor to cooperate with a fixed outer ring to achieve a baffle blocking or moving away from the discharge port, it saves more space compared to existing technologies. Furthermore, the rotation of the fan blades driven by the mixing shaft also rotates the bottom plate and the mixing blades, promoting material discharge and more thorough mixing.
[0004] However, the bottom of the mixing tank in the above patent is designed as a conical structure, and there is a gap between the sleeve, stirring blade, rotating shaft and the bottom of the stirring blade and the bottom of the mixing tank. This makes it difficult for the PP material at the bottom of the mixing tank to be effectively dispersed and mixed, and it is easy to form a mixing dead corner, thus affecting the uniformity of the overall mixture.

[0029] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0030] like Figures 1 to 7 As shown in the figure, this utility model provides a mixer for producing weather-resistant PP material, including a turntable 2. A mixing cylinder 3 is inclinedly arranged on one side of the turntable 2. The mixing cylinder 3 is fixed to the turntable 2 by connecting columns of different lengths. The inclined structure of the mixing cylinder 3 allows the PP material inside to flow back and forth when the mixing cylinder 3 rotates. A cylinder cover 16 is provided at the opening of the mixing cylinder 3 for sealing. A connecting shaft 4, coaxially arranged with the mixing cylinder 3, is rotatably connected to the turntable 2. One end of the connecting shaft 4 passes through the mixing cylinder 3 and extends into the interior of the mixing cylinder 3. A stirring paddle 5 is fixed to the end of the connecting shaft 4 inside the mixing cylinder 3. The rotation of the stirring paddle 5, combined with the flow of PP material inside the mixing cylinder 3, further improves the mixing effect and efficiency. A rotating shaft 9 is fixedly provided on one side of the turntable 2. A drive assembly for driving the rotating shaft 9 to rotate is provided on the side of the turntable 2 near the rotating shaft 9. The rotating shaft 9 has a hollow structure inside and is provided with a gear ring 8. A first gear 7 is meshed on the gear ring 8. A horizontal connecting rod 6 is fixedly provided at one end of the connecting shaft 4 near the turntable 2. The connecting rod 6 is fixedly connected to the first gear 7.
[0031] When the rotating shaft 9 drives the turntable 2 to rotate, the inclined mixing cylinder 3 rotates synchronously, causing the internal materials to flow and mix up and down. Furthermore, the rotation of the turntable 2 drives the connecting shaft 4 to rotate, causing the horizontal connecting rod 6 on the connecting shaft 4 to rotate, which in turn causes the first gear 7 to mesh with the gear ring 8 and rotate, thereby driving the connecting rod 6 and the connecting shaft 4 to rotate, thus realizing the rotation of the stirring paddle 5.
[0032] The mixing cylinder 3 adopts an inclined structure design. When it rotates under the drive of the turntable 2, the PP material inside can form an up-and-down reciprocating flow, enhancing the mixing effect of the material. In addition, the stirring paddle 5 rotates inside the mixing cylinder 3, forming a compound motion with the rotation of the mixing cylinder 3, which helps to improve the dispersion uniformity of the PP material and achieve efficient mixing.
[0033] In some specific implementation plans, such as Figure 1 , Figure 2 and Figure 3As shown, a base 1 is located below the turntable 2, and two frames 17 are fixedly mounted on the top of the base 1. A limiting ring 19 is fixedly mounted on the outer side of the turntable 2. Multiple limiting wheels 18 are rotatably connected between the two frames 17, and the limiting wheels 18 are distributed on the limiting ring 19 in a circumferential rolling fit. A circular through groove is provided on the side of each frame 17 near the top. The inner diameter of the circular through groove is larger than the diameter of the turntable 2 to ensure that the turntable 2 does not contact the frame 17 and cause interference when rotating. The cross-section of the limiting ring 19 is a trapezoidal structure, and a groove is provided in the middle of each limiting wheel 18.
[0034] When turntable 2 rotates, it drives the limiting ring 19 on it to rotate. Since the groove of the limiting wheel 18 cooperates with the trapezoidal structure of the limiting ring 19, it can limit and guide the limiting ring 19 and the turntable 2 on it, which helps to maintain the smooth rotation of turntable 2 and avoid shaking.
[0035] In some specific implementation plans, such as Figure 2 , Figure 4 and Figure 6 As shown, a fixed plate 12 is fixedly mounted on the top of the base 1, and the rotating shaft 9 rotates inside the fixed plate 12 to support the rotation of the rotating shaft 9 and the turntable 2 on it. A fixed ring 14 is fixedly mounted on the fixed plate 12, and the gear ring 8 is fixed to the fixed ring 14 by multiple connecting rods 15 to ensure the stability of the gear ring 8. The drive assembly includes a second gear 10 fixed on the rotating shaft 9, a motor 13 fixed on the fixed plate 12, and a third gear 11 fixed on the output shaft of the motor 13. The third gear 11 meshes with the second gear 10, and the output shaft of the motor 13 passes through the fixed plate 12.
[0036] The motor 13 is started, which drives the third gear 11 to rotate, thereby driving the second gear 10 and the rotating shaft 9 to rotate. The rotating shaft 9 drives the turntable 2 to rotate, thereby rotating the mixing cylinder 3 and causing the PP material to be mixed evenly inside the mixing cylinder 3.
[0037] In some specific implementation plans, such as Figure 1 and Figure 5 As shown, to facilitate the opening and closing of the cylinder cover 16 for loading and unloading, one side of the cylinder cover 16 is hinged to the mixing cylinder 3, and the other side of the cylinder cover 16 is provided with a connecting assembly. The connecting assembly is used to control the opening and closing of the cylinder cover 16. The connecting assembly includes a mounting plate 20 fixed on the mixing cylinder 3, a screw 21 rotating on the mounting plate 20, a connecting plate 22 fixed on the cylinder cover 16, a slot 24 opened inside the connecting plate 22, and a knob 23 threadedly connected to the screw 21. The knob 23 is designed in a quincunx shape for operation. The mounting plate 20 has a U-shaped structure, and the screw 21 is installed inside the U-shaped groove. The screw 21 can be inserted into the slot 24.
[0038] When feeding, loosen knob 23, rotate screw 21 to disengage it from slot 24, open cylinder cover 16 to expose the opening of mixing cylinder 3 for feeding. Close cylinder cover 16, rotate screw 21 to insert it into slot 24, tighten knob 23 to lock connecting plate 22, and ensure mixing cylinder 3 is sealed.
[0039] When discharging, after the mixing drum 3 stops rotating, open the drum cover 16 to discharge the uniformly mixed PP material.
[0040] In some specific implementation plans, such as Figure 7 As shown, both the mixing cylinder 3 and the cylinder cover 16 are designed to be transparent (e.g., fiberglass), which reduces the overall weight of the mixing cylinder 3 and facilitates observation of the mixing of the materials inside. A gap is provided between the connecting rod 15 and the inner wall of the rotating shaft 9, and a gap is also provided between the gear ring 8 and the inner wall of the rotating shaft 9 to prevent contact between the connecting rod 15 and the gear ring 8, thus affecting the normal rotation of the rotating shaft 9.
[0041] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:
[0042] Feed the PP material to be mixed into the mixing cylinder 3. During feeding, the opening of the mixing cylinder 3 is tilted upwards. Loosen the knob 23, turn the screw 21 to disengage it from the slot 24, open the cylinder cover 16 to expose the opening of the mixing cylinder 3 for feeding. Close the cylinder cover 16, turn the screw 21 to insert it into the slot 24, tighten the knob 23 to lock the connecting plate 22, and ensure that the mixing cylinder 3 is sealed.
[0043] The motor 13 is started, driving the third gear 11 to rotate, which in turn drives the second gear 10 and the rotating shaft 9 to rotate. The rotating shaft 9 drives the turntable 2 to rotate, thereby rotating the mixing cylinder 3 and causing the PP material to be mixed evenly inside the mixing cylinder 3. The rotation of the inclined mixing cylinder 3 causes the material inside to flow up and down for mixing. When the turntable 2 rotates, it drives the connecting shaft 4 to rotate, and the horizontal connecting rod 6 on the connecting shaft 4 rotates, causing the first gear 7 to mesh with the gear ring 8 and rotate, thereby driving the connecting rod 6 and the connecting shaft 4 to rotate, thereby rotating the stirring paddle 5.
[0044] The mixing cylinder 3 adopts an inclined structure design. When it rotates under the drive of the turntable 2, the PP material inside can form an up-and-down reciprocating flow, enhancing the mixing effect of the material. In addition, the stirring paddle 5 rotates inside the mixing cylinder 3, forming a compound motion with the rotation of the mixing cylinder 3, which helps to improve the dispersion uniformity of the PP material and achieve efficient mixing.
[0045] After mixing is complete, the opening of the mixing cylinder 3 is tilted downwards. After the mixing cylinder 3 stops rotating, the cylinder cover 16 is opened, and the uniformly mixed PP material can be discharged.
[0046] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
