Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of plastic product mixers, specifically to a mixer with dehumidification function for preparing plastic products. Background Technology

[0002] In the manufacturing process of plastic products, the mixing of raw materials is a crucial step in ensuring product quality. Plastic raw materials (such as resin granules, recycled materials, etc.) are prone to absorbing moisture during storage or transportation due to environmental humidity. If they are directly added to a mixer, it will have many adverse effects on subsequent processing and the performance of the finished product.

[0003] Currently used mixers generally lack dehumidification capabilities, only capable of mechanically mixing raw materials. When the moisture content of the raw materials exceeds the standard, the moisture evaporates upon heating during molding processes such as injection molding and extrusion, forming bubbles. This leads to defects such as dents and cracks on the surface of the finished product, and in severe cases, even melt fracture. To solve this problem, an additional raw material pre-drying process is required in production, using equipment such as hot air dryers. This not only extends the production cycle but also necessitates additional equipment costs and energy consumption.

[0004] Furthermore, pre-dried raw materials easily reabsorb moisture from the air during the transfer to the mixer, especially in high-humidity environments where secondary moisture absorption is more pronounced, making it difficult to guarantee the stability of the drying effect. This disconnected processing method reduces production efficiency and increases the difficulty of quality control, hindering the continuity and economy of plastic product manufacturing. Therefore, developing a mixer with integrated dehumidification function has become an urgent need for the industry to improve production efficiency. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a mixer with dehumidification function for the preparation of plastic products, which solves the technical problem that the mixers currently used in the prior art generally do not have dehumidification function and can only complete the mechanical mixing of raw materials.

[0006] According to one aspect, at least one embodiment of this disclosure provides a mixer with a dehumidification function for preparing plastic articles, comprising:

[0007] The system includes a base, a mixing tank, and a discharge port, wherein the mixing tank is mounted on the base and the discharge port is located at one end of the mixing tank.

[0008] The main frame and the supporting discharge assembly are provided, wherein the main frame is mounted on the base and the supporting discharge assembly is mounted on both the main frame and the base.

[0009] A mixing dehumidification assembly is disposed between the mixing tank and the main frame;

[0010] The mixing dehumidification assembly includes a pair of annular grooves, each of which is formed around the inner surface of the main frame. The mixing tank is slidably fitted inside the annular grooves. A drive wheel that is electrically driven to rotate is provided at the bottom of the main frame. An outer ring layer is provided around the outer surface of the mixing tank, and the outer ring layer is in contact with the surface of the drive wheel.

[0011] As a further technical solution, a number of annular pipes are fixedly connected inside the main frame, and a number of docking grooves are opened around the outer surface of the mixing tank. The annular pipes slide against the outer surface of the mixing tank and are connected to the docking grooves.

[0012] As a further technical solution, the mixing tank is provided with a number of cavity plates inside, and a number of air inlet pipes are arranged around the surface of the cavity plates. One end of the air inlet pipe is fixed to the inner wall of the mixing tank, and the air inlet pipe is connected to the docking groove.

[0013] As a further technical solution, the surface of the cavity plate is provided with a number of dispersing air holes, and the bottom of the number of annular pipes is provided with a main pipe, which is connected to the annular pipes. A disc is rotatably connected to one end of the mixing tank.

[0014] As a further technical solution, the outer side of the disc is fixedly connected to the main frame, a feeding pipe is installed on the disc, and a number of scraper plates are arranged around the inner surface of the mixing tank, with the scraper plates all located at the intervals of the cavity plates.

[0015] As a further technical solution, the supporting discharge assembly includes a pair of supporting legs, both of which are fixed to the bottom of the main frame, and the lower ends of the supporting legs are rotatably connected to the surface of the base via pins.

[0016] As a further technical solution, a pair of hydraulic cylinders are rotatably connected to the bottom of the other end of the main frame and the surface of the base via a pin. A support seat is provided on the surface of the base, and the support seat is attached to the bottom of the main frame.

[0017] As a further technical solution, both the surface of the drive wheel and the surface of the outer ring layer are high-friction anti-slip structural surfaces.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the mixing and dehumidification assembly solves the problem of traditional mixers only mixing but not dehumidifying by combining rotary mixing with hot air dehumidification. When the mixing tank rotates, the shovel plate turns the material, ensuring even heating, while the dispersion holes in the cavity plate eject hot air that directly contacts the material and removes moisture. The sliding connection between the annular pipe and the docking groove ensures an uninterrupted supply of hot air during rotation. This design eliminates the need for a pre-drying process for raw materials, avoids secondary moisture absorption, improves production continuity, ensures uniform mixing of materials, reduces finished product defects caused by moisture, and lowers equipment investment and energy consumption.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-3 As shown, a mixer with dehumidification function for preparing plastic products according to an embodiment of this disclosure is illustrated, comprising:

[0032] The system includes a base 1, a mixing tank 2, and a discharge port 3. The mixing tank 2 is mounted on the base 1, and the discharge port 3 is located at one end of the mixing tank 2.

[0033] The main frame 4 and the supporting discharge assembly 6 are provided. The main frame 4 is mounted on the base 1, and the supporting discharge assembly 6 is mounted on the main frame 4 and the base 1.

[0034] A mixing dehumidification component 5 is disposed in the mixing tank 2 and the main frame 4;

[0035] The mixing dehumidification component 5 includes a pair of annular grooves 5-1, each of which is formed around the inner surface of the main frame 4. The mixing tank 2 is slidably fitted within the annular grooves 5-1. A drive wheel 5-2, electrically driven, is located at the bottom of the main frame 4. An outer ring layer 5-3 is formed around the outer surface of the mixing tank 2, and the outer ring layer 5-3 is in contact with the surface of the drive wheel 5-2. Several annular pipes 5-4 are fixedly connected inside the main frame 4. Several docking grooves 5-5 are formed around the outer surface of the mixing tank 2. The annular pipes 5-4 are slidably fitted around the outer surface of the mixing tank 2 and are connected to the docking grooves 5-5. Several hollow plates 5-6 are provided inside the mixing tank 2. The cavity plate 5-6 has several air inlet pipes 5-7 arranged around its surface. One end of each air inlet pipe 5-7 is fixed to the inner wall of the mixing tank 2. The air inlet pipe 5-7 is connected to the docking groove 5-5. The cavity plate 5-6 has several dispersing air holes 5-8. The bottom of each annular pipe 5-4 is provided with a main pipe 5-9, which is connected to the annular pipe 5-4. A disc 5-10 is rotatably fitted to one end of the mixing tank 2. The outer side of the disc 5-10 is fixedly connected to the main frame 4. A feed pipe 5-11 is installed on the disc 5-10. Several scraper plates 5-12 are arranged around the inner surface of the mixing tank 2. The scraper plates 5-12 are all located at intervals of the cavity plate 5-6.

[0036] In some examples, in order to achieve rolling mixing and hot air dehumidification of materials, a mixing and dehumidification component 5 is designed. This component includes an annular groove 5-1 formed on the inner surface of the main frame 4. The annular groove 5-1 provides a rotation track for the mixing tank 2. The outer surface of the mixing tank 2 slides against the groove. The drive wheel 5-2 at the bottom of the main frame 4 is electrically driven to rotate. Through the friction with the outer ring layer 5-3 of the outer surface of the mixing tank 2, the mixing tank 2 is driven to rotate along the annular groove 5-1.

[0037] The annular pipe 5-4 inside the main frame 4 is fixed by a bracket and slides in connection with the docking groove 5-5 on the outer surface of the mixing tank 2, ensuring that the hot air supply is uninterrupted when the mixing tank 2 rotates. The main pipe 5-9 at the bottom of the annular pipe 5-4 is connected to a hot air device, which delivers hot air to the annular pipe 5-4, then through the docking groove 5-5 and the air inlet pipe 5-7 into the cavity plate 5-6, and finally sprays it out from the dispersion hole 5-8.

[0038] The shovel plate 5-12 inside the mixing tank 2 rotates with the tank body, continuously turning the material to ensure full contact between the material and the hot air ejected from the cavity plate 5-6. The disc 5-10 is fixed on the main frame 4 and rotates with the mixing tank 2, ensuring stable feeding through the feed pipe 5-11 without affecting the rotation of the mixing tank 2. The hot air removes moisture as the material is turned, achieving simultaneous mixing and dehumidification, thus improving processing efficiency.

[0039] like Figures 1-3 As shown in the figure, the supporting discharge assembly 6 in this embodiment includes a pair of supporting legs 6-1. The supporting legs 6-1 are fixed to the bottom of the main frame 4. The lower end of the supporting legs 6-1 is rotatably connected to the surface of the base 1 by a pin. The bottom of the other end of the main frame 4 is rotatably connected to the surface of the base 1 by a pair of hydraulic cylinders 6-2 by a pin. The surface of the base 1 is provided with a support seat 6-3, which is attached to the bottom of the main frame 4.

[0040] In some examples, in order to achieve the effect of rapid material discharge through angle adjustment, a support discharge assembly 6 is designed. This assembly includes a support leg 6-1 fixed to the bottom of the main frame 4. The support leg 6-1 is rotatably connected to the base 1 through a pin to form a swing fulcrum. The hydraulic cylinder 6-2 at the bottom of the other end of the main frame 4 is connected to the main frame 4 and the base 1 through pins at both ends, which can drive the main frame 4 to rotate around the support leg 6-1 to adjust the tilt angle of the mixing tank 2.

[0041] When the mixing tank 2 is in a horizontal state, the support seat 6-3 on the surface of the base 1 fits against the bottom of the main frame 4, providing stable support. When discharge is required, the hydraulic cylinder 6-2 extends to push the main frame 4 to lift, causing the mixing tank 2 to tilt towards the discharge port 3. Under the action of gravity, the material moves along the tank wall towards the discharge port 3, and with the rotation of the shovel plate 5-12, the discharge speed is accelerated.

[0042] The cooperation between the support leg 6-1 and the hydraulic cylinder 6-2 ensures smooth angle adjustment, while the support base 6-3 ensures stability during horizontal stirring. This tiltable structure solves the problem of difficult discharge of viscous materials, allowing the mixed and dehumidified material to be discharged quickly, thus improving the equipment's continuous operation capability.

[0043] For example, such as Figure 2 As shown, both the surface of the drive wheel 5-2 and the surface of the outer ring layer 5-3 are high-friction anti-slip structural surfaces.

[0044] In some examples, the high-friction anti-slip structure surface of the drive wheel 5-2 and the outer ring layer 5-3 adopts an interlaced diamond pattern design. This pattern increases the coefficient of friction when the two are in contact. When the drive wheel 5-2 rotates, it can stably drive the mixing tank 2 to rotate along the annular groove 5-1 through friction, avoiding slippage. Even if the weight of the material inside the mixing tank 2 changes, the anti-slip structure surface can still maintain sufficient friction to ensure the stable rotation speed of the mixing tank 2, guarantee the synergistic effect of the material tipping plate 5-12 and hot air dehumidification, and improve the reliability of equipment operation.

[0045] In actual use: Plastic raw materials are fed into mixing tank 2 through feed pipe 5-11. Support base 6-3 supports the main frame 4 to keep it horizontal. The mixing and dehumidification component 5 is activated. Drive wheel 5-2 drives mixing tank 2 to rotate along annular chute 5-1 through outer ring layer 5-3. The material scraper plate 5-12 inside the tank rotates and turns the material. Hot air is delivered from main pipe 5-9 to annular pipe 5-4, passes through docking groove 5-5 and air inlet pipe 5-7 into cavity plate 5-6, and is sprayed out from dispersion air hole 5-8 to contact the material and remove moisture. Mixing and dehumidification are carried out simultaneously. After completion, support discharge component 6 is activated. Hydraulic cylinder 6-2 extends and pushes main frame 4 to rotate around support leg 6-1, causing mixing tank 2 to tilt towards discharge port 3. The material is discharged through discharge port 3 under the push of gravity and material scraper plate 5-12. Hydraulic cylinder 6-2 retracts to reset the equipment, ready for the next operation.
