Abstract
Description
Technical Field
[0001] This application relates to the field of material mixing equipment technology, and in particular to a uniform mixing device. Background Technology
[0002] During film production, materials need to be mixed first, which involves feeding multiple materials into a mixing mechanism for agitation. Conventional material mixing equipment uses a bottom-mounted conveyor for feeding. The conveyor includes a vertically positioned screw pointing downwards, with the material container placed below it. The rotation of the screw transports the materials to the mixing mechanism for mixing. However, because the materials need to overcome gravity during transport, especially when transporting large granular materials, the materials are prone to falling back into the container due to gravity, leading to deviations in the feeding amount and affecting the material ratio. At the same time, the conveyor directly transports the materials to the mixing mechanism for mixing, resulting in a short mixing time and poor mixing effect for some materials, causing a decrease in the yield of film products. Utility Model Content
[0003] The purpose of this application is to provide a uniform mixing device, which aims to improve the problems of feeding deviation and poor mixing effect that occur when using a bottom-mounted conveying mechanism in related technologies, and to ensure product quality.
[0004] This application provides a uniform mixing device, including a frame and a stirring extrusion structure disposed on the frame, and a conveying mixing structure disposed on the stirring extrusion structure. The conveying mixing structure includes a main mixing component connected to the stirring extrusion structure, a premixing component connected to the main mixing component, and a metering feeding component connected to the premixing component. The metering feeding component includes a metering conveyor, a first metering hopper disposed on the metering conveyor, and a second metering hopper disposed on the premixing component. The first metering hopper and the second metering hopper are located above the metering conveyor.
[0005] Furthermore, the premixing component includes a premixing hopper, a premixing element disposed within the premixing hopper, and an opening / closing element for controlling the conduction of the premixing element; the premixing element includes a premixing barrel, a premixing shaft rotatably connected to the premixing barrel, and a premixing drive element for driving the premixing shaft, wherein the premixing shaft is provided with premixing blades along its length direction.
[0006] Furthermore, the premixing tank has an upper connecting port and a lower connecting port, the upper connecting port being connected to the premixing hopper, and the lower connecting port facing the opening and closing element.
[0007] Furthermore, the opening and closing component includes an opening and closing valve plate slidably connected to the premixing tank and a valve plate driving component for driving the opening and closing valve plate, wherein the opening and closing valve plate closes or opens the lower connecting port.
[0008] Furthermore, the main mixing assembly includes a main mixing hopper, a main mixing shaft rotatably connected to the main mixing hopper, and a main mixing drive component for driving the main mixing shaft, wherein the main mixing shaft is provided with main mixing blades along its length direction.
[0009] Furthermore, the main mixing assembly also includes a cyclone separator, which is disposed in the main mixing hopper.
[0010] Furthermore, the stirring extrusion structure includes an extrusion assembly, a plurality of stirring screw assemblies disposed on the extrusion assembly, and a stirring drive for driving the stirring screw assemblies.
[0011] The beneficial effects of this application are:
[0012] 1. A uniform mixing device according to this application comprises a conveying and mixing structure within a stirring and extrusion structure. This conveying and mixing structure includes a main mixing component, a premixing component, and a quantitative feeding component. During operation, materials are fed into the first and second quantitative hoppers of the quantitative feeding component. The material from the first quantitative hopper is conveyed via a quantitative conveyor to the premixing component, where it mixes with the material from the second quantitative hopper before entering the premixing component for premixing. After premixing, the material is then fed into the main mixing component for secondary mixing. The material after secondary mixing in the main mixing component is then fed into the stirring and extrusion structure. In this process, since the volumes of the first and second quantitative hoppers are preset, quantitative feeding is achieved simply by filling them with material. Simultaneously, the quantitative feeding component utilizes gravity to drive the material into the premixing component, achieving efficient and uniform transport. By adding a conveying and mixing structure for quantitative transfer and premixing of materials, the feeding amount and mixing effect are effectively guaranteed, improving product quality.
[0013] 2. A uniform mixing device of this application includes a premixing component and an opening and closing component. After the quantitative feeding component inputs the material into the premixing component, the opening and closing component closes the premixing component, so that the material can be fully premixed in the premixing tank before being input into the main mixing component. This facilitates the control of the mixing time and ensures the quality of the premixing.
[0014] 3. In a uniform mixing device of this application, the material is premixed in a premixing component and then fed into a main mixing component for further mixing. The material after secondary mixing is then fed into a stirring and extrusion mechanism for stirring and extrusion, which helps to ensure the quality of mixing and extrusion.

[0024] Reference Figure 1 as well as Figure 2This application provides a uniform mixing device, including a frame 1 and a stirring extrusion structure 2 disposed on the frame 1, and a conveying and mixing structure 3 disposed on the stirring and extrusion structure 2. When the uniform mixing device is running, material is fed into the conveying and mixing structure 3, which uniformly conveys and mixes the material before feeding it into the stirring and extrusion structure 2, where the stirring and extrusion structure 2 stirs and extrudes the mixed material.
[0025] Specifically, the frame 1 supports the various structures. The stirring extrusion structure 2 includes an extrusion assembly 21, several stirring screw assemblies 22 disposed on the extrusion assembly 21, and a stirring drive for driving the stirring screw assemblies 22. The extrusion assembly 21 includes an extrusion die, and several stirring screw assemblies 22 are connected to the extrusion die. In this embodiment, there are three stirring screw assemblies 22, which extend along the length of the frame 1. The output end of the stirring screw assemblies 22 is connected to the extrusion die, and the stirring drive is a motor. When the conveying and mixing structure 3 feeds the material into the stirring extrusion structure 2, the stirring screw assemblies 22 will extrude and transport the material. Under the extrusion action, the material heats up and melts, and is extruded from the extrusion die. The stirring extrusion structure 2 is prior art and can be purchased; its specific structure and principle will not be described in detail.
[0026] The conveying and mixing structure 3 is correspondingly arranged on the stirring screw assembly 22. The conveying and mixing structure 3 includes a main mixing assembly 31 connected to the stirring extrusion structure 2, a premixing assembly 32 connected to the main mixing assembly 31, and a quantitative feeding assembly 33 connected to the premixing assembly 32.
[0027] Reference Figure 2 as well as Figure 3 The main mixing assembly 31 is located at the end of the stirring screw assembly 22 away from the extrusion assembly 21. The main mixing assembly 31 includes a main mixing hopper 311, a main mixing shaft rotatably connected to the main mixing hopper 311, and a main mixing drive component for driving the main mixing shaft. The main mixing hopper 311 is vertically arranged, with a feed inlet at its top. The lower end of the main mixing hopper 311 is connected to the stirring screw assembly 22, and the side of the main mixing hopper 311 is connected to the premixing assembly 32. The main mixing hopper 311 has a main mixing chamber inside, and the main mixing shaft is located in the main mixing chamber. The main mixing shaft is vertically arranged, and main mixing blades are arranged along its length. The main mixing drive component is a motor. Driven by the main mixing drive component, the main mixing shaft rotates, causing the main mixing blades to rotate, thereby mixing the materials. In this embodiment, the main mixing assembly 31 further includes a cyclone separator 312, which is disposed above the main mixing hopper 311. The cyclone separator 312 is used to filter and separate dust in the air in the main mixing chamber when processing particulate materials, thereby reducing the dust content and improving the mixing quality of the materials.
[0028] The premixing assembly 32 includes a premixing hopper 321, a premixing component 322 disposed within the premixing hopper 321, and an opening / closing component 323 for controlling the conduction of the premixing component 322. A quantitative feeding assembly 33 is installed and connected to the upper end of the premixing hopper 321. The premixing hopper 321 has a premixing chamber, and the premixing component 322 is disposed within the premixing chamber. After the quantitative feeding assembly 33 feeds in material, the material enters the premixing component 322 within the premixing chamber.
[0029] The premixing unit 322 includes a premixing tank 3221, a premixing shaft 3222 rotatably connected to the premixing tank 3221, and a premixing drive for driving the premixing shaft 3222. The upper end of the premixing tank 3221 has an upper connecting port, which connects to the premixing chamber of the premixing hopper 321. After the material enters the premixing chamber, it will enter through the upper connecting port of the premixing tank 3221. The premixing shaft 3222 is vertically arranged inside the premixing tank 3221. The premixing shaft 3222 has premixing blades arranged along its length. The premixing drive is a motor. Under the drive of the premixing drive, the premixing shaft 3222 rotates, causing the premixing blades to rotate, thereby premixing the material.
[0030] Reference Figure 3 as well as Figure 4 The lower end of the premixing tank 3221 has a lower connecting port facing the opening / closing member 323. The opening / closing member 323 includes an opening / closing valve plate 3231 slidably connected to the premixing tank 3221 and a valve plate drive member for driving the opening / closing valve plate 3231. The opening / closing valve plate 3231 closes or opens the lower connecting port. In this embodiment, the opening / closing member 323 includes an opening / closing guide rail 3232 disposed on the premixing tank 3221. The opening / closing guide rail 3232 is horizontally disposed. The opening / closing valve plate 3231 is slidably connected to the opening / closing guide rail 3232. The valve plate drive member is a cylinder. Under the drive of the valve plate drive member, the opening / closing valve plate 3231 can slide along the opening / closing guide rail 3232 to close or open the lower connecting port.
[0031] A premixing conveying pipe 324 is provided at the lower end of the premixing hopper 321. The premixing conveying pipe 324 is connected to the main mixing hopper 311. The opening and closing valve plate 3231 is located between the premixing conveying pipe 324 and the lower connecting port. After premixing is completed, the opening and closing valve plate 3231 is opened, and the premixed material enters the main mixing hopper 311 through the premixing conveying pipe 324.
[0032] The quantitative feeding assembly 33 includes a quantitative conveying component 331, a first quantitative hopper 332 disposed on the quantitative conveying component 331, and a second quantitative hopper 333 disposed on the premixing assembly 32. The first quantitative hopper 332 and the second quantitative hopper 333 are vertically arranged and located above the quantitative conveying component 331. The second quantitative hopper 333 is connected above and communicates with the premixing hopper 321. The quantitative conveying component 331 is a conveying screw, which is generally horizontally arranged and communicates with the premixing hopper 321. The first quantitative hopper 332 is connected above the conveying screw. Both the first quantitative hopper 332 and the second quantitative hopper 333 are controlled by valves (not shown in the figure) to control the material conveying.
[0033] The upper ends of the first quantitative hopper 332 and the second quantitative hopper 333 are equipped with feeding ports, which can be connected to a suction feeder or a screw conveyor to transport and feed materials. Since the volumes of the first quantitative hopper 332 and the second quantitative hopper 333 are preset and fixed, quantitative material feeding can be achieved simply by filling the first quantitative hopper 332 and the second quantitative hopper 333 with materials. It is worth mentioning that, in order to ensure the uniformity of feeding in the second quantitative hopper 333, a distribution plate is also provided in the premixing hopper 321. The distribution plate is located above the premixing tank 3221 and includes two inclined material plates. After the material is fed into the second quantitative hopper 333, the material falls evenly from both sides into the premixing tank 3221 under the action of the distribution plate. After the material is fed, the material in the first quantitative hopper 332 automatically moves to the quantitative conveyor 331 under the action of gravity and is fed in, where it mixes with the material in the second quantitative hopper 333 and enters the premixing unit 322. Understandably, the number and position of the quantitative hoppers can be adjusted according to actual needs. Specifically, the quantitative hoppers can be detachably connected to the quantitative conveying component 331 and the premixing component 32 to adapt to the feeding amount required by different processes.
