Abstract
Description
Technical Field
[0001] This application relates to the field of granulation equipment technology, and in particular to a plastic granulation equipment based on dual feeding. Background Technology
[0002] Granulation equipment is a molding machine that can shape materials into specific shapes. It works by mixing plastic raw materials and feeding them into the granulator for heating and melting. The molten plastic material is then injected by a rotating screw, cooled and shaped into a blank of the desired specific shape. Finally, the blank is granulated by a pelletizing device to obtain plastic pellets. Plastic pellets can be processed into daily necessities, building components, cable insulation and other products through injection molding, extrusion and other processes.
[0003] As product performance requirements increase, modification processes are often necessary during the production of plastic granules. These processes often involve using a combination of multiple main raw materials and additives to improve the plastic material's resistance to high and low temperatures, tensile and flexural strength, and other properties. Before granulation, all raw materials need to be dried, then mixed evenly in a mixer before being fed into the granulator. In current production, with process optimization, when two main raw materials require different drying temperatures, two dryers are needed to dry the materials separately. After drying, each raw material needs to be manually removed and fed into the mixer for mixing, which is labor-intensive, resource-intensive, and inefficient. Utility Model Content
[0004] To address the aforementioned technical problems, this application provides a plastic granulation device based on dual feeding, comprising a granulator, a mixer disposed at the feed inlet of the granulator, and a support frame mounted above the granulator. The support frame is provided with a first feeding component, and a first drying machine and a second drying machine located on both sides of the first feeding component. A second feeding component is disposed at the bottom of the first drying machine and the second drying machine, respectively. The two second feeding components are connected to the first feeding component, and the first feeding component is connected to the mixer.
[0005] Preferably, the first feeding assembly includes a first driver, a first feeding cylinder, and a first screw disposed in the first feeding cylinder and connected to the first driver, all mounted on the support frame. The first feeding cylinder is connected to two second feeding assemblies.
[0006] Preferably, each of the second feeding components includes a second driver, a second feeding cylinder, and a second screw disposed inside the second feeding cylinder and connected to the second driver, wherein the second feeding cylinder is connected to the first drying machine or the second drying machine.
[0007] Preferably, the support frame is provided with a mounting frame above the first feeding cylinder, and the mounting frame is provided with a connecting pipe communicating with the first feeding cylinder, and the two second feeding cylinders are respectively connected to both sides of the connecting pipe.
[0008] Preferably, the pelletizing unit is also provided at the discharge end of the pelletizer, and a conveying unit is provided below the pelletizing unit.
[0009] As can be seen from the above, the following beneficial effects can be obtained by applying the method provided in this application: By setting a mixer at the feed inlet of the granulator, erecting a support frame above the granulator, setting a first feeding component on the support frame, and setting a first drying machine and a second drying machine on both sides of the first feeding component on the support frame, and setting a second feeding component at the bottom of the first drying machine and the second drying machine respectively, the two second feeding components are connected to the first feeding component, and the first feeding component is connected to the mixer. Thus, the two drying machines can dry two kinds of raw materials at different temperatures, and then the raw materials from the two drying machines are conveyed to the first feeding component through the second feeding component, and then conveyed to the mixer through the first feeding component. The mixer stirs and mixes the raw materials, and then feeds them into the granulator for granulation. Therefore, after feeding from multiple dryers, efficient feeding and mixing can be achieved, improving the degree of automation, saving manpower and material resources, and improving production efficiency.

Figure 2 This is a perspective view of a plastic granulation device based on dual feeding, according to an embodiment of this application. Detailed Implementation
[0012] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Example
[0013] To address the aforementioned technical problems, this embodiment provides a plastic granulation device based on dual feeding, such as... Figure 1-2 As shown, the system includes a granulator 10, a mixer 20 at the feed inlet of the granulator 10, a support frame 30 above the granulator 10, a first feeding assembly 70 on the support frame 30, a first drying machine 40 and a second drying machine 50 located on both sides of the first feeding assembly 70 on the support frame 30, and a second feeding assembly 60 at the bottom of the first drying machine 40 and the second drying machine 50 respectively. The two second feeding assemblies 60 are connected to the first feeding assembly 70, and the first feeding assembly 70 is connected to the mixer 20. Furthermore, the two dryers can dry the two raw materials at different temperatures. The raw materials from the two dryers are then conveyed to the first feeding component 70 via the second feeding component 60. The raw materials are then conveyed to the mixer 20 via the first feeding component 70. The mixer 20 stirs and mixes the raw materials, and then feeds them to the granulator 10 for granulation. Thus, after feeding from multiple dryers, efficient feeding and mixing can be achieved, improving the degree of automation, saving manpower and material resources, and improving production efficiency.
[0014] Specifically, the first feeding assembly 70 includes a first driver 71 mounted on the support frame 30, a first feeding cylinder 72, and a first screw mounted inside the first feeding cylinder 72 and connected to the first driver 71. The first feeding cylinder 72 is connected to two second feeding assemblies 60. For example, the first driver 71 may be a stepper motor. After the two second feeding assemblies 60 feed the raw material into the first feeding cylinder 72, the stepper motor drives the first screw to rotate, thereby the first screw conveys the raw material in the first feeding cylinder 72 to the mixer 20 for mixing.
[0015] The mixer 20 includes a material bucket and an agitator installed on the top cover. The agitator extends into the material bucket. The first feeding cylinder 72 is connected to the material bucket, and the raw materials are then transported into the material bucket through the first feeding cylinder 72, and then mixed by the agitator.
[0016] Furthermore, each second feeding assembly 60 includes a second driver 62, a second feeding cylinder 61, and a second screw disposed within the second feeding cylinder 61 and connected to the second driver 62. The second feeding cylinder 61 is connected to either the first drying machine 40 or the second drying machine 50. The second driver 62 can also be a stepper motor. The two second feeding cylinders 61 are respectively connected to the bottom of the first drying machine 40 and the second drying machine 50, allowing raw materials from the first drying machine 40 and the second drying machine 50 to be fed into the second feeding cylinder 61, and then conveyed into the first feeding cylinder 72 via the second screw of the second feeding cylinder 61. In some embodiments, the first driver 71 and the second driver 62 can be electrically connected to the control console of the granulator 10, thereby controlling the feeding rate of the raw materials in the first drying machine 40 and the second drying machine 50 by controlling the speed of the stepper motor, thus controlling the feeding rate of different raw materials and consequently controlling the mixing ratio of each raw material.
[0017] In the above scheme, the first drying machine 40 and the second drying machine 50 can be connected to the feeding equipment through top connecting pipes. The feeding equipment then transports different raw materials to the first drying machine 40 and the second drying machine 50. The first drying machine 40 and the second drying machine 50 can be set with different drying temperatures to meet the different drying requirements of different raw materials. Alternatively, when it is necessary to combine three or more raw materials with different temperatures, a corresponding number of dryers and feeding components can be installed on the support frame 30, which can be adjusted and combined according to actual conditions. A control valve can be installed at the discharge port at the bottom of each drying machine and connected to the control console of the granulator 10, allowing for manual control of opening and closing. The discharge port is closed when drying is required and opened when feeding is required, improving convenience.
[0018] Furthermore, a mounting frame 74 is provided above the first feeding cylinder 72 on the support frame 30. The mounting frame 74 is provided with a connecting pipe 73 connected to the first feeding cylinder 72. Two second feeding cylinders 61 are respectively connected to both sides of the connecting pipe 73. The raw materials of the two second feeding cylinders 61 are then transported to the connecting pipe 73 and fall into the first feeding cylinder 72. The raw materials are then transported to the mixer 20 by the first screw in the first feeding cylinder 72.
[0019] On the other hand, this embodiment also includes a pelletizing assembly 80 disposed at the discharge end of the pelletizer 10. After the pelletizer 10 extrudes the plastic from the discharge port, it is cut into pellets by the pelletizing assembly 80. At the same time, a conveying assembly 90 is disposed below the pelletizing assembly 80, so that the plastic pellets fall into the conveying assembly 90 and are conveyed to the next process. The specific structures of the pelletizing assembly 80 and the conveying assembly 90 are mature technologies in existing pelletizers and will not be described in detail here.
[0020] In summary, the solution of this application sets up a mixer at the feed inlet of the granulator, erects a support frame above the granulator, and sets up a first feeding component on the support frame. A first drying machine and a second drying machine are located on either side of the first feeding component on the support frame. Second feeding components are respectively set at the bottom of the first and second drying machines, and the two second feeding components are connected to the first feeding component, which in turn connects to the mixer. Thus, the two drying machines can dry two raw materials at different temperatures. The raw materials from the two drying machines are then conveyed to the first feeding component via the second feeding components, and then conveyed to the mixer via the first feeding component. The mixer stirs and mixes the raw materials, which are then fed into the granulator for granulation. Therefore, with multiple dryers feeding the materials, efficient feeding and mixing can be achieved, improving automation, saving manpower and resources, and increasing production efficiency.
[0021] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
