Description

Technical Field

[0001] This application relates to the field of plastic mixing technology, and in particular to an adaptive mixing device for main and auxiliary materials based on three layers. Background Technology

[0002] Plastic masterbatch is a semi-finished plastic product made by mixing high polymer resin with various additives and auxiliaries in a certain proportion and then extruding it into granules. It is mainly used to meet the standardization requirements of plastic processing, storage and transportation. Its core production process includes three key steps: accurate metering, uniform mixing and high-temperature extrusion granulation. The final product is in granular form to achieve efficient storage, convenient transportation and continuous industrial processing of raw materials.

[0003] In related technologies, in a three-layer plastic masterbatch processing system, the process flow follows a vertical layout of "batch-mixing-molding". The batching area on the third floor places plastic and various plastic additives separately and transports them to the mixing area on the second floor. The main materials and auxiliary materials can be added to the mixing cylinder according to the predetermined formula sequence. The output shaft of the drive motor drives the mixing rod to mix, so that the main materials and auxiliary materials are evenly mixed. Finally, the mixture is transported to the molding equipment in the molding area on the first floor for granulation processing.

[0004] However, this method has the following drawbacks: it cannot obtain the ratio of main materials to auxiliary materials and the total weight in real time; the drive motor cannot dynamically adjust its speed according to the ratio of main materials to auxiliary materials and the total weight; when the ratio of main materials to auxiliary materials is unbalanced or the total amount of materials fed is abnormal, the drive motor drives the stirring rod to maintain a fixed stirring speed, which may affect the mixing uniformity of plastic raw materials and the stability of the quality of plastic raw materials. Utility Model Content

[0005] To address the aforementioned issues, this application provides a three-layer adaptive mixing device for main and auxiliary materials.

[0006] The three-layer adaptive mixing device for main and auxiliary materials provided in this application adopts the following technical solution: A three-layer adaptive mixing device for main and auxiliary materials is installed in the mixing area on the second floor. It receives the main and auxiliary materials from the batching area on the third floor, mixes them to form a mixture, and then supplies the mixture to the molding equipment in the molding area on the first floor. The device includes a machine base, an electronic scale, a controller, a mixing cylinder, a feeding assembly, and a first mixing assembly. The electronic scale is fixedly connected to one end of the machine base, and the controller is fixedly connected to the other end of the machine base. Several feeding assemblies are provided, with one end fixed above and connected to the mixing cylinder, and the other end connected to the batching area on the third floor. The mixing cylinder is located above the electronic scale. The first mixing assembly includes a stirring rod and a first drive motor. The stirring rod is built into the mixing cylinder, and the output shaft of the first drive motor passes through the bottom of the mixing cylinder and is coaxially fixed to the stirring rod. The controller is electrically connected to the feeding assembly, the electronic scale, and the first drive motor.

[0007] By adopting the above technical solution, several feeding components receive the main and auxiliary materials conveyed from the third-floor batching area to the mixing drum. An electronic scale at the bottom of the mixing drum is used to weigh the main material, the auxiliary materials, and the total weight of the main and auxiliary materials. The controller is electrically connected to the electronic scale and the feeding components. Based on the preset formula ratio of the main and auxiliary materials, the electronic scale monitors the conveyed weight and total weight of the main and auxiliary materials in real time. The controller controls the feeding components conveying the main material; when the required proportion of the main material is reached, the feeding components will stop conveying the main material. The controller further sequentially controls the feeding components for various auxiliary materials; when the required proportion of the auxiliary materials is reached, the feeding components will stop conveying the auxiliary materials. Simultaneously, the controller and the first drive... The motor is electrically connected to the control unit. The output shaft of the first drive motor dynamically adjusts its speed based on the weight of the main and auxiliary materials and the total weight reflected by the electronic scale. Since the output shaft of the first drive motor is coaxially fixed with the stirring rod built into the mixing cylinder, it further drives the stirring rod to dynamically adjust the stirring intensity. The stirring rod agitates the main and auxiliary materials. When the ratio of the main and auxiliary materials is normal, it maintains a standard speed, ensuring mixing efficiency and increasing the uniformity of the mixture formed by the main and auxiliary materials. At the same time, if the ratio of the main and auxiliary materials is unbalanced or the total amount of materials fed is abnormal, the controller can adjust the speed of the first drive motor in real time, reducing the impact on the mixing uniformity and mixing quality stability of the main and auxiliary materials.

[0008] Preferably, the mixing cylinder includes a mixing cylinder body and a cover plate. A positioning post is provided on the top edge of the mixing cylinder body, and a positioning hole is provided at the corresponding position on the cover plate. The positioning post and the positioning hole are inserted into each other. One end of a plurality of feeding components is fixed above the cover plate and communicates with the interior of the mixing cylinder body.

[0009] By adopting the above technical solution, the mixing cylinder achieves the positioning connection between the mixing cylinder body and the cover plate and the quick assembly and disassembly of the mixing cylinder body and the cover plate through the insertion and cooperation of the positioning post of the mixing cylinder body and the positioning hole of the cover plate. Since one end of the feeding component is fixed above the cover plate and connected to the inside of the mixing cylinder body, the insertion and cooperation of the positioning post and the positioning hole reduces the positional displacement of the cover plate caused by the vibration generated by the feeding component.

[0010] Preferably, the third-floor batching area includes batching cylinders, and several batching cylinders are provided. The feeding assembly includes a feed inlet, a connector, and a feed switch. The feed switch is located between the feed inlet and the connector. One end of the feed switch is fixedly connected to the feed inlet, and the other end of the feed switch is fixedly connected to the connector. The end of the feed inlet away from the feed switch is fixedly connected to and communicates with the bottom of the batching cylinder. The end of the connector away from the feed switch is fixedly connected to and communicates with the top of the cover plate and the mixing cylinder body. The feed switch is electrically connected to the controller.

[0011] By adopting the above technical solution, the third-floor batching area, through multiple independently set batching cylinders and feeding components, achieves separate storage and precise feeding of main materials and auxiliary materials. At the same time, the feeding switch is electrically connected to the controller. The controller controls the feeding switch to further control the conveying ratio of main materials and auxiliary materials to the mixing cylinder. The controller controls the feeding switch for conveying main materials. When the weight requirement of the main material is reached, the feeding switch will close, preventing the main material from entering the connector and mixing cylinder from the feeding port. The controller further controls the feeding switches for conveying various auxiliary materials in sequence. When the proportion requirement of the auxiliary materials is reached, the feeding switch will close, preventing the auxiliary materials from entering the connector and mixing cylinder from the feeding port.

[0012] Preferably, the device includes a spiral discharge assembly located between the electronic scale and the mixing cylinder. The spiral discharge assembly is fixedly connected to the electronic scale and connected to the molding equipment in the molding area on the first floor. The bottom of the mixing cylinder is inclined, and a discharge port is provided at the lowest inclined end of the mixing cylinder. A conveying switch is provided between the mixing cylinder and the spiral discharge assembly. One end of the conveying switch is fixedly connected to the discharge port, and the other end of the conveying switch is fixedly connected to the spiral discharge assembly. The conveying switch is electrically connected to the controller.

[0013] By adopting the above technical solution, before the main material and auxiliary material are mixed, the conveying switch is closed, preventing the mixed material from entering the screw discharge assembly through the discharge port. After the main material and auxiliary material are mixed, since the conveying switch is electrically connected to the controller, the controller drives the conveying switch to open, and the mixed material enters the screw discharge assembly from the discharge port. Since the screw discharge assembly is connected to the molding equipment in the first-floor molding area, the screw discharge assembly drives the mixed material into the molding equipment in the first-floor molding area.

[0014] Preferably, the spiral discharge assembly includes a second drive motor, a discharge cylinder, and a spiral rod. The discharge cylinder is horizontally fixed below the mixing cylinder, and the spiral rod is built into the discharge cylinder. The second drive motor is located at the end of the discharge cylinder away from the discharge port. The output shaft of the second drive motor passes through the discharge cylinder and is coaxially fixed with the spiral rod. The discharge cylinder is provided with a feed pipe, and the other end of the material conveying switch is fixedly connected to the feed pipe.

[0015] By adopting the above technical solution, after the main material and auxiliary material are mixed, the controller issues a discharge command and the material conveying switch is turned on. Since the output shaft of the second drive motor passes through the screw rod built into the discharge cylinder and is coaxially fixed, the second drive motor drives the screw rod to rotate synchronously in the discharge cylinder. The axial thrust of the screw rod continuously pushes the mixed material that falls into the mixing cylinder from the feed pipe through the discharge port to the first floor molding equipment, thus realizing the forced push output of the mixed material.

[0016] Preferably, the spiral discharge assembly further includes a discharge pipe, which is connected to the molding equipment in the molding area on the first floor. The discharge pipe is vertically fixedly connected to and communicates with the end of the discharge cylinder near the feed pipe.

[0017] By adopting the above technical solution, after the main material and auxiliary material are mixed, the controller issues a discharge command. The output shaft of the second drive motor drives the screw rod to rotate, forcibly pushing the material falling into the mixing cylinder along the discharge cylinder to the discharge pipe. Since the discharge pipe is fixed vertically to the discharge cylinder, it ensures that the mixed material flows smoothly into the molding equipment in the molding area on the first floor under the action of gravity along the discharge pipe.

[0018] Preferably, a discharge pipe cover is provided at the end of the discharge pipe away from the molding equipment in the first-floor molding area, and the discharge pipe cover is hinged to the discharge pipe.

[0019] By adopting the above technical solution, operators can quickly open the discharge pipe cover to visually inspect the internal condition of the discharge pipe, which facilitates the confirmation of the conveying status of the mixed material and the residual condition of the mixed material during daily inspections.

[0020] Preferably, a second stirring assembly is provided above the mixing cylinder. The second stirring assembly includes a third drive motor, a rotating shaft, and a stirring impeller. The stirring impeller is sleeved on the rotating shaft and is coaxially fixed with the rotating shaft. The stirring impeller is built into the mixing cylinder. The output shaft of the third drive motor passes through the top of the mixing cylinder and is coaxially fixed with the rotating shaft.

[0021] By adopting the above technical solution, after the main material and auxiliary material are put into their respective batching cylinders, since the output shaft of the third drive motor is coaxially fixed with the rotating shaft built into the batching cylinder, and the stirring impeller is coaxially fixed with the rotating shaft, the output shaft of the third drive motor drives the stirring impeller to rotate through the rotating shaft. The shearing force of the stirring impeller breaks up the agglomeration of the main material and auxiliary material, promotes the initial uniform dispersion of the main material and auxiliary material with different particle sizes or densities, reduces the uneven mixing caused by large pieces of main material and auxiliary material directly entering the mixing cylinder, and shortens the mixing time of the subsequent mixing of main material and auxiliary material.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. An electronic scale and a first mixing component are installed at the bottom of the mixing drum in the mixing area on the second floor. They receive the main and auxiliary materials from the batching area on the third floor in real time through multiple feeding components. The electronic scale weighs the main material, auxiliary material, and total mixing amount simultaneously. The controller dynamically adjusts the start and stop of each feeding component based on the preset formula ratio of the main and auxiliary materials. When the main and auxiliary materials reach the preset ratio, the corresponding feeding is automatically cut off. At the same time, based on the real-time reflection of the main material weight, auxiliary material weight, and total weight by the electronic scale, the controller controls the speed of the first drive motor, which in turn drives the speed of the mixing rod to implement dynamic mixing. 2. The third-floor batching area is connected to the mixing cylinder via multiple independent batching cylinders using feeding components. The controller sequentially opens and closes the feeding switches of each feeding component according to the preset ratio of main materials and auxiliary materials. When the main materials and auxiliary materials reach the preset ratio, the feeding switch of the corresponding feeding component is automatically closed. 3. Before the main material and auxiliary material are mixed, the conveying switch is closed to prevent the mixed material from entering the screw discharge component. After the main material and auxiliary material are mixed, the controller drives the conveying switch to open, and the mixed material enters the screw discharge component. The screw discharge component drives the mixed material into the molding equipment in the molding area on the first floor. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] This application discloses a three-layer adaptive mixing device for main and auxiliary materials. (Refer to...) Figure 1 and Figure 2 The three-layer adaptive mixing device for main and auxiliary materials is set in the mixing area on the second floor. It is used to receive the main and auxiliary materials conveyed from the batching area on the third floor. After mixing the main and auxiliary materials, the mixture is fed to the molding equipment in the molding area on the first floor. In this embodiment, the process of the main and auxiliary materials is described in detail.

[0032] Reference Figure 3 Correspondingly, the third-floor batching area includes several batching cylinders 1 and a second mixing component 2. In this embodiment, there are three batching cylinders 1, one of which carries the main material and the other two of which carry the auxiliary material. The batching cylinders 1 are evenly fixed on the ground of the third-floor batching area, and each batching cylinder 1 is equipped with a corresponding second mixing component 2.

[0033] Specifically, taking one of the batching cylinders 1 as an example, the batching cylinder 1 has an inverted cone-shaped structure, with three support rods 3 evenly arranged on its outer peripheral wall. One end of the support rod 3 is fixedly connected to the batching cylinder 1, and the other end of the support rod 3 is fixedly connected to the ground of the batching area on the third floor. By setting three support rods 3 to form a three-point fixation, the batching cylinder 1 is provided with vertical load-bearing support, which reduces the deformation of the batching cylinder 1 due to the pressure of the main material or auxiliary material, as well as the shaking or displacement of the batching cylinder 1.

[0034] Reference Figure 4 Furthermore, the second stirring assembly 2 includes a third drive motor 21, a rotating shaft 22, and a stirring impeller 23. In this embodiment, two stirring impellers 23 are provided. The two stirring impellers 23 are vertically sleeved on the rotating shaft 22 and coaxially fixed with the rotating shaft 22. The output shaft of the third drive motor 21 passes through the top of the feeding cylinder 1 and is coaxially fixed with the rotating shaft 22. In addition, a feeding port 11 is provided on one side of the top of the feeding cylinder 1. The feeding port 11 is provided with a feeding gate 12. The feeding gate 12 is hinged to the edge of the feeding port 11 and is used to cover the feeding port 11.

[0035] This explains that when the main material and auxiliary material are fed into their respective mixing cylinders 1 through the feeding port 11, the output shaft of the third drive motor 21 is coaxially fixed with the rotating shaft 22 built into the mixing cylinder 1, and the stirring impeller 23 is coaxially fixed with the rotating shaft 22. The output shaft of the third drive motor 21 drives the rotating shaft 22 to rotate, which in turn drives the stirring impeller 23 to rotate. The shearing force of the stirring impeller 23 is used to break up the agglomeration of the main material and auxiliary material, promote the initial uniform dispersion of the main material and auxiliary material with different particle sizes or densities, reduce the uneven mixing caused by large pieces of main material and auxiliary material directly entering the mixing cylinder 7, and shorten the mixing time of the subsequent mixing of the main material and auxiliary material.

[0036] Furthermore, after the main ingredients and auxiliary ingredients are initially and evenly dispersed, they are fed into the three-layer adaptive mixing device for main ingredients and auxiliary ingredients in the mixing area on the second floor. The device includes a machine base 4, an electronic scale 5, a controller 6, a mixing cylinder 7, a feeding component 8, a spiral discharge component 9, and a first mixing component 10.

[0037] Correspondingly, three feeding components 8 are also provided, which are respectively set at the bottom of the batching cylinder 1 and connected to the batching cylinder 1. Specifically, the feeding component 8 includes a feeding port 81, a feeding switch 82, and a connecting member 83. In this embodiment, the feeding switch 82 is set as a pneumatic butterfly valve. One end of the pneumatic butterfly valve is fixedly connected to the feeding port 81, and the other end of the pneumatic butterfly valve is fixedly connected to the connecting member 83. The end of the feeding port 81 away from the pneumatic butterfly valve is fixedly connected to the bottom of the batching cylinder 1 in the third-floor batching area and connected to the batching cylinder 1. The ends of the connecting members 83 away from the pneumatic butterfly valve are all fixedly connected to and connected to the mixing cylinder 7. After the main material and auxiliary material are initially and evenly dispersed in the batching cylinder 1 in the third-floor batching area, they are then transported to the mixing cylinder 7 in the second-floor mixing area through the feeding component 8.

[0038] Furthermore, the mixing cylinder 7 includes a mixing cylinder body 71 and a cover plate 72. A positioning post 711 is provided on the top edge of the mixing cylinder body 71, and a positioning hole 721 is provided at the corresponding position on the cover plate 72. The positioning post 711 and the positioning hole 721 are inserted and matched, which realizes the positioning connection between the mixing cylinder body 71 and the cover plate 72 and the quick assembly and disassembly of the mixing cylinder body 71 and the cover plate 72, and reduces the positional displacement of the cover plate 72 caused by the vibration generated by the feeding component 8.

[0039] Reference Figure 5 Meanwhile, the upper surface of the cover plate 72 is provided with a connecting part 722. Both the connecting part 83 and the connecting part 722 are cylindrical. The diameter of the connecting part 83 is larger than the diameter of the connecting part 722. The inner wall of the connecting part 83 is fitted onto the outer wall of the connecting part 722. The outer wall of the connecting part 83 is provided with a clamp 16, which fixes the connecting part 83 to the connecting part 722.

[0040] On the other hand, the electronic scale 5, controller 6, spiral discharge assembly 9 and first mixing assembly 10 are all set at the bottom of the mixing cylinder 7 via the machine base 4, and the machine base 4 is fixedly connected to the ground of the mixing area on the second floor.

[0041] Correspondingly, the electronic scale 5 is fixedly connected to one end of the machine base 4, and the spiral discharge assembly 9 is fixed on the electronic scale 5. Specifically, the spiral discharge assembly 9 includes a second drive motor 91, a discharge cylinder 92, and a spiral rod 93. The second drive motor 91 is fixed on the electronic scale 5, the discharge cylinder 92 is horizontally set above the electronic scale 5, and the spiral rod 93 is built into the inside of the discharge cylinder 92. The output shaft of the second drive motor 91 passes through the discharge cylinder 92 and is coaxially fixed with the spiral rod 93 inside the discharge cylinder 92.

[0042] Reference Figure 6Furthermore, the first stirring assembly 10 includes a first drive motor 101 and a stirring rod 102. The bottom of the mixing cylinder 7 is inclined. The stirring rod 102 is built into the inside of the mixing cylinder 7. The output shaft of the first drive motor 101 passes through the inclined bottom surface of the mixing cylinder 7, and the output shaft of the first drive motor 101 is coaxially fixed with the stirring rod 102.

[0043] In addition, a discharge port 712 is provided at the lowest inclined end of the mixing cylinder 7, and a feed pipe 921 is provided at the corresponding position of the discharge cylinder 92. A feed switch 13 is provided between the discharge port 712 and the feed pipe 921. In this embodiment, the feed switch 13 is also set as a pneumatic butterfly valve. One end of the pneumatic butterfly valve is fixedly connected to the discharge port 712, and the other end of the pneumatic butterfly valve is fixedly connected to the feed pipe 921.

[0044] Furthermore, the controller 6 is fixed at the end of the machine base 4 away from the mixing cylinder 7, and the feed switch 82, the conveying switch 13, the electronic scale 5 and the first drive motor 101 are all electrically connected to the controller 6.

[0045] In addition, the spiral discharge assembly 9 also includes a discharge pipe 14, which is a cylindrical structure. The discharge pipe 14 is connected to the molding equipment in the molding area on the first floor. The discharge pipe 14 is vertically fixed and connected to the end of the discharge cylinder 92 near the conveying pipe. The end of the discharge pipe 14 away from the molding equipment in the molding area on the first floor is provided with a discharge pipe cover 15, which is hinged to the discharge pipe 14.

[0046] This explains that the electronic scale 5 at the bottom of the mixing cylinder 7 is used to weigh the main material, the various auxiliary materials, and the total weight of the main material and auxiliary materials. According to the preset formula ratio of the main material and auxiliary materials, the electronic scale 5 can monitor the weight of the main material, the weight of the various auxiliary materials, and the total weight of the main material and auxiliary materials in real time. The controller 6 controls the feeding switch 82. When the weight requirement of the main material is reached, the controller 6 controls the feeding switch 82 of the main material, and the feeding switch 82 will close, and the feeding component 8 will no longer feed the main material. When the weight requirement of the auxiliary materials is reached, the controller 6 further controls the feeding switch 82 of the auxiliary materials in sequence, and the feeding switch 82 will close, and the feeding component 8 will no longer feed the auxiliary materials.

[0047] Meanwhile, the controller 6 is electrically connected to the first drive motor 101. The output shaft of the first drive motor 101 dynamically adjusts its speed according to the weight of the main material and auxiliary material and the total weight reflected by the electronic scale 5. Since the output shaft of the first drive motor 101 is coaxially fixed to the stirring rod 102 inside the mixing cylinder 7, the stirring rod 102 is further driven to dynamically adjust the stirring intensity. The stirring rod 102 stirs the main material and auxiliary material. When the ratio of the main material and auxiliary material is normal, the standard speed is maintained, which ensures the mixing efficiency of the main material and auxiliary material and increases the uniformity of the mixture formed by the mixing of the main material and auxiliary material. At the same time, if the ratio of the main material and auxiliary material is unbalanced or the total amount of material is abnormal, the speed of the first drive motor 101 can be adjusted in real time, which reduces the impact on the mixing uniformity and mixing quality stability of the main material and auxiliary material.

[0048] Furthermore, after the main material and auxiliary material are mixed evenly, the controller 6 issues a discharge command, the material conveying switch 13 is turned on, and the mixed material enters the feed pipe 921 through the discharge port 712, and further enters the discharge cylinder 92. The output shaft of the second drive motor 91 drives the spiral rod 93 inside the discharge cylinder 92 to rotate, forcibly pushing the mixed material falling into the mixing cylinder 7 along the discharge cylinder 92 to the discharge pipe 14. Since the discharge pipe 14 is vertically fixed to the discharge cylinder 92, it is ensured that the mixed material flows smoothly into the molding equipment in the first-floor molding area under the action of gravity along the discharge pipe 14. The operator can quickly open the discharge pipe cover 15 to visually check the internal condition of the discharge pipe 14, which is convenient for confirming the conveying status of the mixed material and the residual condition of the mixed material during daily inspection.

[0049] The implementation principle of the three-layer main material and auxiliary material adaptive mixing device in this application embodiment is as follows: the main material and various auxiliary materials are respectively fed into their respective mixing cylinders through the feeding port. The output shaft of the third drive motor drives the rotating shaft to drive the mixing impeller to rotate, so as to pre-stir the main material and various auxiliary materials to break up the clumps and achieve preliminary uniform dispersion.

[0050] According to the preset formula ratio, the controller sequentially turns on and off the feed switches at the bottom of each batching cylinder. The main material is fed through the feed inlet to the connector and then to the mixing cylinder. The electronic scale weighs the material in real time and sends the feedback to the controller. Once the set value of the main material is reached, the feed switch of the main material is turned off. Then, the auxiliary materials are fed through the feed inlet to the connector and then to the mixing cylinder in sequence according to their type. Once the set value of each auxiliary material is reached, the corresponding feed switch is turned off.

[0051] After the main ingredients and auxiliary ingredients enter the mixing drum, the controller dynamically adjusts the speed of the first drive motor based on the real-time weighing data from the electronic scale. This drives the first drive motor to stir the main ingredients and auxiliary ingredients. If an imbalance in the ratio of main ingredients and auxiliary ingredients or abnormal feeding is detected, the speed of the first drive motor is immediately adjusted to ensure the uniformity of mixing and the stability of quality.

[0052] After mixing is completed, the controller turns on the feeding switch of the feeding port. The mixed material enters the feeding pipe of the spiral discharge assembly through the discharge port at the inclined bottom, and further enters the discharge cylinder. The spiral rod is built into the discharge cylinder. The second drive motor drives the spiral rod to rotate, forcibly pushing the mixed material along the horizontal discharge cylinder to the discharge pipe. Gravity makes the mixed material flow smoothly into the molding equipment on the first floor. The operator can open the hinged discharge pipe cover at any time to visually check the mixing and conveying status and residue inside the discharge pipe, which is convenient for daily inspection and troubleshooting.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
