Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of plastic product mixing machines, specifically, to a plastic product mixing machine. Background Technology

[0002] In the production process of plastic products, the uniformity of raw material mixing directly affects the quality and performance of the product. Currently, most plastic product mixing machines on the market adopt a structure with a single mixing shaft and fixed blades. Their mixing principle mainly relies on the rotation of the shaft to drive the material to make circular motion, and the initial mixing is achieved through the contact between the blades and the material. However, this traditional structure has obvious limitations: on the one hand, the position of the stirring shaft is fixed, which causes the material to form a fixed movement trajectory in the stirring chamber. The material near the chamber wall and bottom is prone to stirring dead zones and is difficult to fully mix with the material in the central area; on the other hand, the angle and shape of the blades are not adjustable, and for mixed raw materials with large differences in density and particle size, it cannot adapt to the flow characteristics of different materials and is prone to stratification. Furthermore, traditional mixing machines offer relatively uniform mixing intensity. For materials requiring high-intensity mixing, extended mixing times are often necessary, reducing production efficiency and potentially damaging the physical properties of some raw materials due to over-mixing. These issues make existing mixing machines insufficient to meet the requirements of high-precision plastic product manufacturing for uniform raw material mixing. Therefore, a new type of mixing equipment with optimized mixing structure and improved mixing effect is urgently needed. Utility Model Content To overcome the above-mentioned defects, the embodiments of this disclosure provide a plastic product mixing machine, which solves the technical problem of simple mixing structure and poor mixing effect in the prior art.

[0003] According to one aspect, at least one embodiment of this disclosure provides a plastic article mixing machine, comprising: A mixing tank and a discharge port, wherein the discharge port is located on the outer wall of the mixing tank; The bottom plate and the first mixing and discharging assembly are provided, wherein the bottom plate is disposed at the bottom of the mixing tank and the first mixing and discharging assembly is disposed in the mixing tank; The tank includes several top plates and a second stirring assembly, wherein the top plates are fixed to the top of the mixing tank and the second stirring assembly is disposed on the top plates; The first mixing and discharging assembly includes a pair of fixed columns, both of which are fixed to the bottom of the mixing tank. A movable plate is movably connected to the lower end of each fixed column. The movable plate is rotatably connected to a central shaft inside the bottom of the mixing tank. The central shaft is driven to rotate by electricity, and a pair of mixing blades are provided on the central shaft.

[0004] As a further technical solution, the base plate is provided with an eccentric shaft that is driven to rotate by electricity. One end of the eccentric shaft is rotatably connected to the movable plate by a connecting rod through a pin. The bottom of the mixing tank is rotatably fitted with a transmission sleeve.

[0005] As a further technical solution, the transmission sleeve is fitted outside the central shaft, and a drive gear that is driven to rotate by electricity is provided at the bottom of the mixing tank. An external gear is provided on the outer surface of the transmission sleeve, and the drive gear meshes with the external gear.

[0006] As a further technical solution, a number of pusher plates are arranged around the side surface of the transmission sleeve, and a control cylinder is arranged vertically downward on the outer wall of the mixing tank. A sealing plate is provided at the output end of the control cylinder, and the sealing plate is attached to the outer wall of the mixing tank.

[0007] As a further technical solution, the second stirring assembly includes a pair of chutes, which are formed on the upper surface of the top plate. A movable seat is slidably connected in the chutes, and a stirring frame driven by electricity is provided at the bottom of the movable seat. Several second cylinders are provided at the top of the stirring tank, and the output end of the second cylinders is connected to the movable seat.

[0008] As a further technical solution, the pusher plate has an arc-shaped transition structure.

[0009] As a further technical solution, the stirring blades are generally spiral in shape.

[0010] As a further technical solution, a pair of reinforcing rods are provided on the upper surface of the sealing plate, and the reinforcing rods are slidably fitted in the outer wall of the mixing tank.

[0011] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the first mixing and discharging assembly solves the problems of simple traditional mixing structures and dead zones through the rotation and lifting of the mixing blades and the rotation of the pusher plate. The spiral blades, moving up and down, can agitate materials at different depths, preventing material accumulation at the bottom; the pusher plate rotates with the transmission sleeve, both assisting in mixing and efficiently pushing materials to the discharge port. The sealing plate and control cylinder work together to precisely control the discharge, and the reinforcing rod improves the sealing stability.

[0020] like Figures 1-3 As shown, a plastic product mixing machine according to an embodiment of the present disclosure is illustrated, comprising: A mixing tank 1 and a discharge port 2, wherein the discharge port 2 is formed on the outer wall of the mixing tank 1; The bottom plate 3 and the first stirring and discharging component 5 are provided. The bottom plate 3 is disposed at the bottom of the mixing tank 1, and the first stirring and discharging component 5 is disposed in the mixing tank 1. A plurality of top plates 4 and a second stirring assembly 6, wherein the top plates 4 are all fixed to the top of the mixing tank 1, and the second stirring assembly 6 is disposed on the top plates 4; The first mixing and discharging assembly 5 includes a pair of fixed columns 5-1, both of which are fixed to the bottom of the mixing tank 1. A movable plate 5-2 is movably connected to the lower end of each fixed column 5-1. A central shaft 5-3 is rotatably connected to the bottom of the mixing tank 1 via the movable plate 5-2. The central shaft 5-3 is electrically driven to rotate and has a pair of mixing blades 5-4 mounted on it. An eccentric shaft 5-5, also electrically driven to rotate, is mounted on the bottom plate 3. One end of the eccentric shaft 5-5 is rotatably connected to the movable plate 5-2 via a pin and a connecting rod 5-6. The mixing tank 1... A transmission sleeve 5-7 is connected to the bottom rotating assembly. The transmission sleeve 5-7 is fitted outside the central shaft 5-3. A drive gear 5-8, which is driven to rotate by electricity, is provided at the bottom of the mixing tank 1. An external gear 5-9 is provided on the outer surface of the transmission sleeve 5-7. The drive gear 5-8 meshes with the external gear 5-9. Several pusher plates 5-10 are provided around the side surface of the transmission sleeve 5-7. A control cylinder 5-11 is vertically downward provided on the outer wall of the mixing tank 1. A sealing plate 5-12 is provided at the output end of the control cylinder 5-11. The sealing plate 5-12 is attached to the outer wall of the mixing tank 1.

[0021] In some examples, to achieve efficient mixing, a first mixing and discharging assembly 5 is designed. This assembly includes a pair of fixed columns 5-1 vertically fixed at the bottom of the mixing tank 1, the lower ends of which are movably fitted with a movable plate 5-2, providing vertical guidance for the movable plate 5-2. The movable plate 5-2 is rotatably connected to a central shaft 5-3 inside the bottom of the mixing tank 1 via bearings. The central shaft 5-3 is electrically driven to rotate, and a pair of mixing blades 5-4 on the shaft rotate synchronously with it, which can mix the material inside the tank.

[0022] The eccentric shaft 5-5 on the base plate 3 is electrically driven to rotate. One end is rotatably connected to the connecting rod 5-6 via a pin, and the other end of the connecting rod 5-6 is rotatably connected to the movable plate 5-2. When the eccentric shaft 5-5 rotates, it drives the movable plate 5-2 to move up and down along the fixed column 5-1 via the connecting rod 5-6, thereby causing the central shaft 5-3 and the stirring blades 5-4 to rise and fall synchronously, achieving stirring of materials at different depths. The transmission sleeve 5-7 at the bottom of the mixing tank 1 is rotatably fitted outside the central shaft 5-3. The external gear 5-9 on its outer surface meshes with the drive gear 5-8 at the bottom of the mixing tank 1. The drive gear 5-8 is electrically driven and can drive the transmission sleeve 5-7 to rotate independently. The pusher plate 5-10 on the side surface of the transmission sleeve 5-7 rotates with it, pushing the material towards the discharge port 2.

[0023] The output end of the control cylinder 5-11 on the outer wall of the mixing tank 1 is connected to the sealing plate 5-12. The sealing plate 5-12 fits against the tank wall and can control the opening and closing of the discharge port 2. During mixing, the sealing plate 5-12 closes the discharge port 2; during discharge, the control cylinder 5-11 moves the sealing plate 5-12 away, and the pusher plate 5-10 pushes the material to the discharge port 2 for discharge. This component achieves thorough mixing and efficient discharge of materials through the rotation and lifting of the central shaft 5-3, the pushing of the pusher plate 5-10, and the control of the sealing plate 5-12.

[0024] like Figures 1-3 As shown, this embodiment proposes that the second stirring assembly 6 includes a pair of chute 6-1, the chute 6-1 is formed on the upper surface of the top plate 4, a movable seat 6-2 is slidably connected in the chute 6-1, a stirring frame 6-3 driven by electricity is provided at the bottom of the movable seat 6-2, and a plurality of second cylinders 6-4 are provided at the top of the stirring tank 1, the output end of the second cylinders 6-4 is connected to the movable seat 6-2.

[0025] In some examples, to further improve mixing efficiency, a second mixing assembly 6 is designed. This assembly includes a pair of parallel grooves 6-1 on the upper surface of the top plate 4. A slider at the bottom of the movable seat 6-2 is slidably connected to the grooves 6-1 and can move laterally along the grooves 6-1. The mixing frame 6-3 at the bottom of the movable seat 6-2 is electrically driven to rotate, which can mix the materials below.

[0026] Several second cylinders 6-4 are located at the top of the mixing tank 1. The cylinder bodies are fixed to the top plate 4, and the output ends are connected to the movable seat 6-2, which can drive the movable seat 6-2 to slide back and forth along the slide groove 6-1. When the second cylinders 6-4 extend or retract, the movable seat 6-2 drives the stirring frame 6-3 to move laterally inside the tank. Combined with the rotation of the stirring frame 6-3 itself, the material around the outer perimeter of the mixing tank 1 can be fully stirred, compensating for the problem of insufficient stirring of the material near the tank wall by the first stirring component.

[0027] This component expands the mixing range and makes the materials in the tank more evenly mixed through the sliding engagement of the slide 6-1 and the movable seat 6-2, the driving of the second cylinder 6-4, and the rotation of the stirring frame 6-3. The stable sliding of the movable seat 6-2 and the efficient rotation of the stirring frame 6-3 work together to improve the overall mixing effect and meet the requirements for material mixing uniformity in the production of plastic products.

[0028] For example, such as Figure 3 As shown, the pusher plate 5-10 has an arc-shaped transition structure.

[0029] In some examples, the pusher plate 5-10 has an arc-shaped transition structure, the curvature of which matches the inner wall of the bottom of the mixing tank 1. The arc design reduces resistance during pushing, allowing the pusher plate 5-10 to push the material more smoothly towards the discharge port 2, preventing material from accumulating at the edges of the pusher plate 5-10. At the same time, the arc transition reduces the shear force on the material, protecting the integrity of the material particles, which is especially suitable for fragile plastic raw materials, improving discharge efficiency and material quality.

[0030] For example, such as Figure 3 As shown, the stirring blades 5-4 have an overall spiral structure.

[0031] In some examples, the stirring blades 5-4 have an overall spiral structure, with the blade edges maintaining an appropriate gap from the inner wall of the mixing tank 1. The spiral structure generates axial thrust during rotation, flipping the material at the bottom upwards. Combined with the up-and-down movement of the central shaft 5-3, this achieves vertical cyclic mixing of the material. This design enhances the three-dimensional mixing effect, allowing materials at different levels to fully contact each other, improving mixing uniformity, and shortening mixing time.

[0032] For example, such as Figure 1 As shown, a pair of reinforcing rods 7 are provided on the upper end face of the sealing plate 5-12, and the reinforcing rods 7 are slidably fitted in the outer wall of the mixing tank 1.

[0033] In some examples, the reinforcing rod 7 on the upper surface of the sealing plate 5-12 is vertically fixed, and its upper end is slidably fitted into the guide sleeve on the outer wall of the mixing tank 1. The reinforcing rod 7 and the control cylinder 5-11 form a triangular support structure, enhancing the stability of the sealing plate 5-12 and preventing it from tilting when sliding against the tank wall. At the same time, the guide sleeve ensures that the reinforcing rod 7 moves vertically, allowing the sealing plate 5-12 to fit tightly against the tank wall, preventing material leakage and improving the reliability of discharge control.

[0034] In actual use: Plastic raw materials are placed into mixing tank 1, and the control cylinder 5-11 pushes the sealing plate 5-12 to close the discharge port 2. The first mixing and discharging assembly 5 is started, and the electric drive center shaft 5-3 rotates, causing the spiral mixing blades 5-4 to mix the material. Simultaneously, the eccentric shaft 5-5 rotates, driving the movable plate 5-2 to move up and down along the fixed column 5-1 via the connecting rod 5-6, causing the mixing blades 5-4 to rise and fall, tumbling the material at different depths. The drive gear 5-8 meshes with the external gear 5-9, driving the transmission sleeve 5-7 to rotate, and the pusher plate 5-10 rotates with it to assist in material mixing. The second mixing assembly 6 is started, and the second cylinder 6-4 pushes the movable seat 6-2 to slide along the slide groove 6-1 of the top plate 4. The mixing frame 6-3 at the bottom of the movable seat 6-2 rotates, mixing the materials inside and outside the tank. The two stirring structures work together to ensure that the materials are mixed evenly. After the mixing is completed, the control cylinder 5-11 pulls the sealing plate 5-12 to open the discharge port 2, and the pusher plate 5-10 sends the materials out through the discharge port 2. The reinforcing rod 7 ensures that the sealing plate 5-12 moves stably.
