[0043] Specifically, the shell 10 is the external structure of the plastic granule molding equipment, which is used to accommodate and support other components and protect the internal mechanism from the influence of the external environment. Provide structural support and protection for the equipment to ensure the stability and safety of the equipment. The transmission assembly 20 is located on the first shell 11, and provides driving force for the plastic granule molding equipment by transmitting power, so that the extrusion mechanism 30 can operate. The extrusion mechanism 30 is located on the second shell 12, and is composed of a screw 31 and a barrel 32. The screw 31 is connected to the transmission assembly 20 to form a material chamber 33, which is used to heat, compress and extrude the plastic particles. The plastic particles are heated, compressed and extruded by the extrusion mechanism 30 to realize the production of plastic products.

[0044] Furthermore, the heating device 40 includes a heating element 41 and a hot air hood 42, which are used to heat the tube 32 of the extrusion mechanism 30 so that the plastic particles can be melted and formed. The temperature of the extrusion mechanism 30 is increased to uniformly heat the plastic particles, thereby ensuring the fluidity and formability of the plastic particles. Multiple heating devices 40 are arranged in sequence along the length direction of the extrusion mechanism 30, which can achieve a more uniform heating effect and avoid the problem of local overheating or burning of the plastic particles.

[0045] The above-mentioned plastic granule forming equipment can achieve a more uniform heating effect by evenly covering the heated air on the tube 32 of the extrusion mechanism 30 through the hot air cover 42. The hot air transfers heat energy to the plastic granules so that they are evenly heated, avoiding the problem of local overheating or burning, thereby improving the product quality. Multiple heating devices 40 are arranged in sequence along the length direction of the extrusion mechanism 30, which can heat the entire extrusion mechanism 30 more evenly. Arranging the heating devices 40 at different positions can further eliminate the problem of uneven heating of the traditional single heating device 40, ensuring that the plastic granules maintain a uniform temperature distribution during the entire extrusion process.

[0046] In a specific embodiment, the hot air cover 42 includes an outer shell 421 and an inner shell 422 . The inner shell 422 is attached to the tube 32 . The outer shell 421 and the inner shell 422 enclose a hot air chamber 43 .

[0047] Specifically, the outer shell 421 and the inner shell 422 are two main components of the hot air cover 42. The outer shell 421 plays the role of external protection and structural support, and the inner shell 422 is attached to the tube 32 to form a closed space. The outer shell 421 protects the internal mechanism from the influence of the external environment and physical damage, and the inner shell 422 and the tube 32 are attached to form a closed hot air chamber 43, which is conducive to centralized heating and improves heating efficiency.

[0048] Furthermore, the inner shell 422 is in direct contact with and in contact with the tube 32, ensuring that the heat can be directly transferred to the surface of the tube 32, thereby achieving effective heating of the plastic particles. The heating effect is enhanced, energy loss is avoided, and the efficiency and uniformity of heating are improved, thereby improving the molding quality of the plastic particles. The combination of the outer shell 421 and the inner shell 422 forms a closed space for accommodating the hot air generated by the heating device 40, and transferring the heat energy to the surface of the tube 32. The formation of a closed hot air chamber 43 is conducive to the centralized heating of the hot air, reduces the loss of energy and the influence of the external environment on the heating effect, and improves the efficiency and uniformity of heating.

[0049] In a specific embodiment, an air outlet 424 is formed on a side of the housing 421 away from the heating element 41 .

[0050] Specifically, the housing 421 is provided with an air outlet 424 on one side of the heating element 41, so that the heated hot air can be discharged to avoid overheating and local burning. The overheated hot air can be effectively discharged to prevent excessive accumulation of hot air during the heating process, avoid local overheating or burning of plastic particles, and improve product quality. The air outlet 424 is located on the side of the housing 421 away from the heating element 41, and is used to discharge the heated hot air and maintain the ventilation cycle inside the hot air chamber 43. The hot air is discharged through the air outlet 424, the air circulation inside the hot air chamber 43 is maintained, the temperature is reduced, and the quality problems of the plastic particles caused by overheating are avoided.

[0051] Furthermore, an air outlet 424 is provided on the side away from the heating element 41 to ensure that the heating element 41 can fully exert its heating function and improve the heating efficiency. The setting of the air outlet 424 can discharge the heated hot air to the outside of the hot air cover 42 to prevent the hot air from directly affecting the working area of ​​the heating element 41. The influence of the hot air on the heating element 41 is avoided, ensuring that the heating element 41 can stably provide heat energy, and ensuring the uniformity and stability of heating. The interference of external factors on the heating element 41 is reduced, and the reliability and continuity of heating are improved.

[0052] In a specific embodiment, the housing 421 includes a first portion 421a and a second portion 421b that are threadedly fixed, the air outlet 424 is disposed on the first portion 421a, and a sealing layer 423 is disposed between the first portion 421a and the second portion 421b.

[0053] Specifically, the threaded fixing design of the first part 421a and the second part 421b can make the shell 421 more stable during assembly, ensuring the safety and sealing of the shell 421. Threaded fixing can ensure the stable connection of the shell 421, avoid the loosening of the shell 421 due to vibration or displacement during use, thereby ensuring the stability and safety of the device. The air outlet 424 is located above the first part 421a, which can effectively discharge the heated hot air to the outside and avoid the accumulation of hot air inside the device. Ensure that the inside of the device is well ventilated, prevent the accumulation of hot air inside the device, maintain the normal working environment of the device, and improve the stability and reliability of the device.

[0054] Furthermore, the provision of the sealing layer 423 can effectively prevent the hot air from leaking from the connection of the housing 421, ensuring that the hot air inside the heating device 40 is effectively and centrally guided to the air outlet 424. This ensures the centralized heating effect of the hot air, avoids energy waste and reduced heating effect, and improves the efficiency and uniformity of heating.

[0055] The first part 421a and the second part 421b of the housing 421 are fixedly connected by threads, ensuring the stability and sealing of the housing 421. The hot air generated by the heating device 40 forms a high temperature environment inside the housing 421, and the hot air flows inside the housing 421 and is guided to the air outlet 424. The hot air inside the device is discharged to the outside through the air outlet 424, maintaining the ventilation state inside the device and ensuring the uniformity and stability of heating.

[0056] In a specific embodiment, a plurality of grooves 422 a are formed on the inner shell 422 along the length direction of the tube 32 , and the plurality of grooves 422 a are equidistantly arranged on the inner shell 422 .

[0057] Specifically, the design of the groove 422a can increase the contact area between the inner shell 422 and the tube 32, enhance the heat conduction effect, and improve the uniformity of heating. By increasing the contact area, the groove 422a can transfer heat more effectively, making the heating more uniform, avoiding the occurrence of local overheating or overcooling, and improving the molding quality of the product. The equidistant arrangement of the grooves 422a can make the hot air evenly distributed on the surface of the inner shell 422, ensuring the uniformity and stability of heating. The equidistant arrangement of the grooves 422a can ensure that the hot air flows and transfers heat evenly on the surface of the inner shell 422, avoiding uneven heating effects and local overheating, and improving the molding quality of the plastic particles.

[0058] In a specific embodiment, the heating device 40 further includes an air duct 44 , the heating element 41 is disposed on a side of the air duct 44 , the air duct 44 is disposed on the hot air hood 42 , and an output end of the air duct 44 is connected to the hot air chamber 43 .

[0059] Specifically, the heating element 41 is located on the side of the air duct 44, so that the hot air can be directly guided and transferred through the air duct 44, ensuring that the heating effect is more concentrated and effective. The heat energy generated by the heating element 41 can directly act on the inside of the air duct 44, realizing centralized heating of the hot air, and improving the efficiency and uniformity of heating. As a part of the heating device 40, the air duct 44 is installed on the hot air hood 42, and plays a role in guiding and distributing the hot air. The setting of the air duct 44 can effectively guide the hot air to the designated position, avoid the loss and waste of hot air during the heating process, and improve the efficiency and accuracy of heating. Being connected to the hot air chamber 43, the heated hot air can be directly guided to the part that needs to be heated, ensuring the concentration and uniformity of the heating effect, and improving the processing quality and production efficiency of the product.

[0060] In a specific embodiment, the plastic granule forming equipment further includes a pressure regulating device 50 , which is disposed on a side of the tube 32 away from the transmission assembly 20 and extends into the material chamber 33 for regulating the pressure in the tube 32 .

[0061] Specifically, the pressure regulating device 50 is arranged on the side of the tube 32 away from the transmission assembly 20, which can more accurately sense the pressure change at the output end, thereby more effectively adjusting the pressure during the processing, and ensuring the consistency and quality stability of the product molding. Furthermore, the pressure regulating device 50 extends into the material cavity 33 to directly monitor the pressure change inside the tube 32 for real-time adjustment. Located inside the material cavity 33, the pressure change inside the tube 32 can be sensed in time, thereby realizing rapid adjustment of the pressure during the processing, maintaining the stability of the pressure, and improving the molding quality of the product.

[0062] In a specific embodiment, the extrusion mechanism 30 also includes a diverter plate 34 , the tube 32 includes a pushing portion 321 and an extrusion portion 322 arranged in sequence, the screw 31 is arranged in the pushing portion 321 , and the diverter plate 34 is arranged between the pushing portion 321 and the extrusion portion 322 .

[0063] Specifically, the diverter plate 34 is located between the pusher portion 321 and the extruder portion 322, and is used to divert the plasticized melt and control its flow direction. The diverter plate 34 is used to ensure that the plastic particles can be evenly distributed during the flow process, and helps to control the flow direction of the material to prevent improper flow direction or uneven mixing, thereby improving the quality and stability of the molded product. The pusher portion 321 is located in front of the diverter plate 34, and is responsible for pushing and compressing the plasticized melt.

[0064] Furthermore, the extrusion part 322 is located behind the diverter plate 34, and extrude the plasticized melt processed by the push part 321 and perform molding. The arrangement of the push part 321 and the extrusion part 322 helps to continuously and uniformly process the plastic particles, ensure the stability and consistency of the processing process, and improve the quality of the molded products. The screw 31 is located in the push part 321, and is responsible for pushing the plastic particles to the extrusion part 322. Under the rotation and pushing action of the screw 31, the plastic particles can be pushed to the diverter plate 34, and sufficient pressure is provided to compress and extrude them, thereby ensuring the uniformity and continuity of the plastic particles and improving the processing efficiency and quality of the products.

[0065] Furthermore, the porous plate, as part of the extrusion mechanism 30, is installed at the front end of the barrel and plays a supporting and fixing role to ensure the stable operation of the barrel and other components. When the plasticized melt is pushed forward by the screw 31 and generates a rotational motion, it will become a linear motion after passing through the porous plate. This design of changing the direction of movement is conducive to the flow of the plasticized melt inside the barrel, making it more uniform and stable. The holes on the porous plate can prevent impurities in the melt or incompletely melted materials from passing through, playing a role of filtering and removing impurities. In this way, the purity and quality of the molding material can be guaranteed.

[0066] The presence of the porous plate increases the resistance of the molten material, which helps to control the flow rate of the plasticized molten material and improve its plasticization quality in the barrel. By increasing the resistance, the heating and plasticization process of the plastic particles can be better controlled to ensure the molding quality of the product.

[0067] In a specific embodiment, the thread of the screw 31 gradually changes from deep to shallow along the length direction of the screw 31, and the deeper end of the thread of the screw 31 is arranged at the end of the screw 31 close to the transmission assembly 20, and the shallower end is arranged at the end close to the extrusion portion 322.

[0068] Specifically, this design enables the processing sections of the screw 31 to have different processing capabilities and functions in the length direction. The change in the depth of the thread is conducive to controlling the processing process of the plastic particles in different sections, so that it can gradually complete the transportation, plasticization and mixing of the plastic, thereby improving the processing efficiency and product quality of the extrusion mechanism 30. The deeper end of the thread is arranged at the end close to the transmission assembly 20, and the shallower end is arranged at the end close to the extrusion part 322, so that different sections of the screw 31 have different functions and processing effects at different positions in the mechanism. The deeper end of the screw 31 is responsible for more preliminary material processing, such as the transportation and compression of plastic particles; while the shallower end is more responsible for the plasticization and mixing of plastic particles, which is conducive to improving the uniformity and plasticization effect of plastic particles.

[0069] Furthermore, in the feeding section, the deep thread design of the screw 31 is conducive to efficiently pushing the plastic particles and compressing them to an appropriate pressure for further processing. When reaching the melting section, the thread gradually becomes shallower, which is conducive to improving the plasticization effect of the plastic particles and increasing the contact area with the heating device 40, thereby promoting uniform heating and plasticization of the plastic particles. Finally, in the homogenization section, the shallower thread of the screw 31 is conducive to further mixing and homogenizing the plastic particles, ensuring the quality and stability of the molded product.

[0070] In a specific embodiment, the plastic granule forming device further includes a feeding member 60 , which is disposed at one end of the tube 32 close to the transmission assembly 20 , and a feeding port of the feeding member 60 is communicated with the material chamber 33 .

[0071] Specifically, by arranging the feed piece 60 near one end of the transmission assembly 20, the feeding process of the plastic particles can be controlled and optimized. This design can ensure that the feed piece 60 can fully utilize the depth of the thread at the end of the transmission assembly 20 to achieve more effective support and transportation of materials, thereby improving the efficiency and stability of feeding. The feed port is directly connected to the material cavity 33 of the extrusion mechanism 30, achieving a smooth transition of the plastic particles from the feed piece 60 into the extrusion mechanism 30. This design can reduce the resistance and loss of the material during the feeding process, ensure the continuity and stability of the material, and thus help improve the processing efficiency and product quality of the extruder.

[0072] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
