Description

Technical Field

[0001] The invention relates to the technical field of plastic drain board processing, in particular to a plastic drain board processing melting device. Background Art

[0002] The plastic drain board processing and melting device is a device used to process plastic drain boards. It is mainly composed of heating elements, melting tanks, extruders or injection molding machines and other components. Its main function is to melt plastic particles or sheets by heating, and then form the shape of drain boards by extrusion or injection molding. This device is usually used to produce plastic products such as drain boards and drain ditch covers. The heating element can be an electric heating tube, a heating ring, or heated by hot air to provide the heat energy required for melting. The melting tank is an area for accommodating plastic particles or sheets. Under the action of heating, the plastic melts into a liquid here, or the plastic particles are heated during the extrusion process. The extruder or injection molding machine is used to extrude or inject the molten plastic into a mold to form the desired shape of the drain board. The operating process of the entire device usually includes the steps of raw material input, heating and melting, extrusion or injection molding, and finally a plastic drain board product that meets the requirements is obtained.

[0003] In a traditional melting device, the uneven distribution of heating media, such as hot air or heating elements, will cause some areas to be heated more while other areas are not heated enough, resulting in the heat not being evenly transferred to the processed material, thereby causing uneven heating. During the heating process, the extruder position is usually heated by a heating element, but due to certain losses in the energy conduction process, a portion of the heat cannot be completely absorbed by the extrusion component, thereby generating excess heat. If the excess heat cannot be discharged, the plastic raw material will be overheated, causing it to melt unevenly or partially deteriorate, thereby affecting the processing quality. In addition, dust, impurities and other substances that may exist in the processing environment, or factors such as humidity and temperature in the air may affect the heating process in the hot melt component, resulting in dust or excess heat. Therefore, the present invention discloses a plastic drainage board processing and melting device to meet the requirements of uniform heating of plastic particles or sheets. Summary of the invention

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0034] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] like Figures 1 to 8As shown, the plastic drainage board processing and melting device includes a frame 1, a rotating motor 2 is arranged on one side of the frame 1, and a reduction box 3 is fixedly installed on one side of the top of the frame 1, and a belt transmission is formed between the rotating motor 2 and the reduction box 3; an extrusion component is arranged on one side of the top of the frame 1, and the extrusion component is used to extrude the plastic raw material, and the extrusion component includes an extrusion tube 4, and a threaded extrusion rod is arranged inside the extrusion tube 4, and the threaded extrusion rod is fixedly connected to the output end of the reduction box 3, and a feeding hopper 5 for feeding is arranged on the top of one side of the extrusion tube 4; a hot melt component is arranged on the outer surface of the extrusion tube 4, and the hot melt component is used to heat the extrusion component, and the hot melt component includes a heating cavity 6 and a feeding cavity 6 which are sleeved on the outside of the extrusion tube 4. A wind cavity 7, and a plurality of hot air blowers 8 fixedly mounted on the frame 1, an air inlet pipe 9 is arranged between the hot air blowers 8 and the air inlet cavity 7 to communicate with each other; a suction component, which is arranged at the top of the heating cavity 6, and the suction component is used to absorb excess heat in the hot melt component or clean up dust in the hot melt component, and the suction component includes a purification box 26 fixedly mounted on the top of the heating cavity 6, and two suction motors 27 fixedly mounted on one side of the purification box 26, wherein a metal connector 10 is arranged at one end of the air inlet pipe 9 close to the air inlet cavity 7, an air inlet 11 adapted to the metal connector 10 is opened at the bottom end of the air inlet cavity 7, and an air outlet 17 is also arranged on one side of the top of the air inlet cavity 7 to communicate with the inside of the heating cavity 6;

[0036] First, the plastic raw material enters the extrusion tube 4 through the feed hopper 5, and the threaded extrusion rod arranged in the extrusion tube 4 pushes the raw material forward for extrusion. During the extrusion process, the hot melt component outside the extrusion tube 4 plays a role in heating the plastic raw material, making it soft and easy to extrude during the extrusion process. This heating effect helps to reduce the viscosity of the plastic, thereby improving the extrusion efficiency and ensuring the smoothness and uniformity of the surface of the molded product. At the same time, the hot air provided by the hot air blower 8 enters the air inlet cavity 7 and the heating cavity 6 through the air inlet pipe 9 to provide the necessary thermal energy for the heating process. The supply of this hot air ensures that the plastic raw material is fully heated during the extrusion process, so that it reaches the appropriate extrusion temperature, which is conducive to maintaining the quality and stability of the extruded product. During the extrusion process, the suction component plays a role in cleaning or absorbing excess heat or dust through the negative pressure generated by the suction motor 27. This suction effect can effectively reduce the pollutants or impurities that may be generated during the extrusion process, and ensure the purity and quality of the extruded product. Finally, the extruded plastic product is smoothly discharged through the extrusion port to complete the entire processing process.

[0037] like Figure 4 , Figure 5 , Figure 6As shown in the figure, a vertical plate is fixedly installed in the middle of the bottom end inside the air inlet cavity 7. On one side of the bottom end inside the air inlet cavity 7, a first guide plate 12 is also fixedly installed. The air inlet 11 is located between the vertical plate and the first guide plate 12. The top cross-section of the first guide plate 12 is arranged in an inverted "V" shape. On one side of the top end inside the air inlet cavity 7, a second guide plate 13 is fixedly installed. The second guide plate 13 is located directly above the air inlet 11 and is arranged in an obtuse angle shape. On one side inside the air inlet cavity 7, a third guide plate 14 is also fixedly installed. The third guide plate 14 is arranged in an inclined shape. One side of the third guide plate 14 cooperates with the second guide plate 13, and the other side of the third guide plate 14 is located at the bottom of the air outlet 17. A plurality of flow guide plates 15 are also arranged on the upper surface of the third guide plate 14. The plurality of flow guide plates 15 are all arranged in an inverted "V" shape, and the plurality of flow guide plates 15 are arranged in a nested doll shape;

[0038] The presence of the vertical plate and the first guide plate 12 helps to guide the air entering the air inlet cavity 7 to flow along a specific path. The air inlet 11 is located between the vertical plate and the first guide plate 12. This setting can guide the air into the cavity and prevent the air from directly passing through the air inlet 11 and entering the heating cavity 6, so that the hot air can evenly flow through the extrusion assembly. The second guide plate 13 is located directly above the air inlet 11 and is arranged in an obtuse angle shape, which helps to further guide the air entering the cavity to flow downward and prevent the air flow from directly hitting. The third guide plate 14 is arranged in an inclined shape. One side of it cooperates with the second guide plate 13, and the other side is located at the bottom of the air outlet 17, which can guide the heated air to the air outlet 17 to ensure that the hot air evenly covers the extrusion assembly, thereby ensuring the uniform heating of the plastic raw material during the extrusion process. The inverted "V" shape arrangement of the flow guide plates 15 further improves the uniformity of air flow.

[0039] As Figure 3 , Figure 7 shown in the figure, a flow guide module is also fixedly installed on one side of the air outlet 17. The flow guide module is used to guide the hot air. The flow guide module includes a fixed column 18, a fan blade 20 and a stirring blade 22. The fixed column 18 is fixedly installed on one side of the air outlet 17. The other end of the fixed column 18 is fixedly installed with a fixing plate 19. The fan blade 20 is rotatably installed on one side of the fixing plate 19. The stirring blade 22 is rotatably installed on the other side of the fixing plate 19. A connecting rod 21 is arranged between the fan blade 20 and the stirring blade 22 to connect them. The fan blade 20 is arranged in an arc shape. The stirring blade 22 is arranged in a fan shape. The middle of the connecting rod 21 is arranged in a "Ji" shape. A fixed seat 23 is also fixedly installed at the top of the fixing plate 19. A rotating plate 24 is rotatably installed at the top of the fixed seat 23. A rotating block 25 is rotatably installed on one side of the rotating plate 24. The other end of the rotating block 25 is sleeved on the middle of the connecting rod 21;

[0040] First, hot air enters the diversion module from one side of the air outlet 17. The diversion module consists of a fixed column 18, a fan blade 20, and a stirring blade 22. The fixed column 18 is fixed on one side of the air outlet 17, and a fixed plate 19 is installed at the other end thereof. The fan blade 20 and the stirring blade 22 are respectively rotatably installed on both sides of the fixed plate 19 and are connected together by a connecting rod 21. Secondly, the flow of the hot air is guided and stirred by the arc shape of the fan blade 20 and the fan-shaped design of the stirring blade 22. The middle part of the connecting rod 21 between the fan blade 20 and the stirring blade 22 is arranged in a "Ji" shape so that they can move coordinately to ensure that the hot air is evenly guided and stirred. A rotating plate 24 is installed at the top of the fixed seat 23, and a rotating block 25 on the rotating plate 24 is sleeved on the middle part of the connecting rod 21. Therefore, when the fan blade 20 rotates, it drives the connecting rod 21 to rotate, and then drives the rotating block 25 to move up and down, further adjusting the flow direction and stirring effect of the hot air.

[0041] As Figure 1 , Figure 2 , Figure 8 shown, connection pipes 28 are respectively arranged on one side of two suction motors 27. The two connection pipes 28 are arranged oppositely. The other end of the connection pipe 28 is fixedly connected with a suction joint 29. Both suction joints 29 are communicated with the air inlet cavity 7. The suction joint 29 penetrates through the bottom end of the air inlet cavity 7 and is arranged between the vertical plate and the third guide plate 14;

[0042] By respectively arranging connection pipes 28 on one side of two suction motors 27 and communicating them with the suction joints 29, a suction channel is formed. This suction channel can effectively guide the excess heat or dust in the hot melt assembly. The suction joint 29 penetrates through the bottom end of the air inlet cavity 7 and is arranged between the vertical plate and the third guide plate 14. Such a position setting enables the suction joint 29 to effectively absorb the excess heat or dust in the hot melt assembly and will not interfere with the normal progress of the heating and extrusion processes. In this way, it is possible to prevent the excess heat or dust from interfering with the production process and ensure the smooth progress of production and the stable quality of the product.

[0043] Those of ordinary skill in the art should understand that the discussion of any above embodiment is only exemplary and is not intended to imply that the scope of the present invention is limited to these examples; under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above, which are not provided in detail for the sake of brevity.
