[0023] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0024] like Figure 1-Figure 5As shown, a waste plastic processing, recycling and regeneration device includes a supporting base 1, a collecting chamber 2, a processing base 3, a processing chamber 4, a space adjustment component 5, a supporting base plate 6, a heating rod 7 and a stirring component 8.

[0025] Among them, the collecting bin 2 is fixedly connected to the top of the supporting base 1, the processing base 3 is fixedly connected to the top of the collecting bin 2, the processing bin 4 is fixedly connected to the top of the processing base 3, and the space adjustment component 5 is installed inside the processing bin 4.

[0026] It should be noted that the collection bin 2 described in this embodiment is fixedly connected to the top of the support base 1, and is used to receive the waste plastic residues generated by the upper processing process, and serves as a transition structure connecting the processing base 3 and the support base 1 to enhance the stability of the overall device. The processing base 3 is fixedly connected to the top of the collection bin 2, and plays a role in supporting the upper processing bin 4 and its internal components to ensure structural strength and vibration control during the processing process. The processing bin 4 is fixedly connected to the top of the processing base 3, and is the main melting and stirring area for waste plastics. Its internal space is used to accommodate and heat plastic materials. The space adjustment component 5 is installed inside the processing bin 4, and the space size of the heating area can be adjusted according to demand during the processing process, thereby adapting to the plastic melting requirements under different feed amounts and improving heating efficiency and melting uniformity.

[0027] The supporting base plate 6 is fixedly connected to the inner bottom of the processing chamber 4 , and a plurality of discharge holes 61 are formed on the supporting base plate 6 .

[0028] It should be noted that the supporting base plate 6 described in this embodiment is fixedly connected to the inner bottom of the processing bin 4, and is used to support the heating rod 7 and the waste plastic material above it, playing the role of stable support and heat transfer assistance, ensuring that the position of the plastic is fixed and evenly heated during the heating process. A plurality of discharge holes 61 are opened on the supporting base plate 6, which are evenly distributed on the surface of the base plate, and are used to achieve smooth discharge of liquid plastic after the plastic is fully melted, preventing the melt from accumulating in the processing bin 4 and affecting subsequent processing. At the same time, the setting of the discharge holes 61 helps to enhance the heat convection effect, accelerate heat conduction, and further improve the overall efficiency of plastic melting and the smoothness of discharge.

[0029] One end of the heating rod 7 is fixedly connected to the top of the supporting base plate 6 , the space adjustment component 5 is sleeved on the heating rod 7 , and two groups of stirring components 8 are provided and symmetrically installed on the space adjustment component 5 .

[0030] It should be noted that one end of the heating rod 7 described in this embodiment is fixedly connected to the top of the supporting base plate 6, which is used to provide continuous and stable heat energy to the waste plastic above. It forms close thermal contact with the supporting base plate 6 to ensure the heating efficiency and stability of heat conduction. The space adjustment component 5 is sleeved on the heating rod 7 and cooperates with the heating rod 7 through a sliding structure. It can move up and down according to the feeding amount of waste plastic, thereby dynamically adjusting the effective space of the heating area, improving the thermal energy utilization efficiency and the uniformity of plastic melting. The stirring component 8 is provided with two groups and is symmetrically installed on the space adjustment component 5. By reasonably arranging the stirring position, the plastic can be heated more evenly during the heating process, and at the same time, the plastic can be prevented from accumulating or burning in local areas, effectively improving the overall melting effect and the processing quality of recycled plastics.

[0031] Specifically, during use, the support base 1 provides overall stability, and the waste plastic raw materials are fed into the processing bin 4 from the top. The heating rod 7 continuously releases heat energy by being tightly connected to the supporting base 6, and efficiently heats and melts the waste plastic in the area. Depending on the amount of material fed, the space adjustment component 5 slides along the heating rod 7 in the processing bin 4 to adjust the spatial height of the heating area, thereby achieving dynamic switching of heat concentration or dispersion, so that the heating area matches the volume of the waste plastic, thereby avoiding heat waste or insufficient heating. The stirring component 8 is symmetrically mounted on the space adjustment component 5, and continuously stirs the waste plastic during the heating process, further promoting uniform heating and sufficient melting. The melted liquid plastic can be smoothly discharged through the discharge holes 61 evenly distributed on the supporting base 6, effectively avoiding plastic accumulation. This structure can flexibly adjust the heating space according to different feeding conditions, overcoming the thermal efficiency mismatch problem caused by the fixed space of the heating area in the existing technology. When the feeding amount is insufficient, the heating space can be reduced to concentrate the heat energy to prevent heat dispersion and local overheating. When the feeding amount increases, the heating area can be expanded to ensure that the entire plastic is fully melted, thereby significantly improving the heating efficiency, melting uniformity and quality of recycled materials, reducing energy consumption and enhancing the adaptability and process stability of the device.

[0032] Furthermore, if Figure 1-Figure 5 As shown, the space adjustment assembly 5 includes a lower pressure plate 51, a support arm 52, a support top plate 53 and a first drive device 54, wherein the lower pressure plate 51 and the support top plate 53 are both slidably clamped on the inner wall of the processing chamber 4, and a plurality of support arms 52 are arranged in a circular array between the top of the lower pressure plate 51 and the bottom of the support top plate 53, and are connected through a plurality of support arms 52. The first drive device 54 is installed on the top of the processing chamber 4, and the output end of the first drive device 54 is fixedly connected to the top of the support top plate 53.

[0033] Furthermore, the top of the processing base 3 is symmetrically fixedly connected to the support rod 31, the top of the outer wall of the processing chamber 4 is fixedly connected to the feed hopper 32, the outer wall of the feed hopper 32 is fixedly connected to the end of the support rod 31, the lower pressure plate 51 is slidably sleeved on the heating rod 7, and the upper and lower sides of the lower pressure plate 51 are symmetrically fixedly connected to the limiting sleeve, and the limiting sleeve is slidably sleeved on the heating rod 7.

[0034] It should be noted that the first driving device 54 described in this embodiment is a cylinder, and the lower pressure plate 51 and the supporting top plate 53 are respectively fixed to the inner wall of the processing chamber 4 by sliding and snapping, so as to realize stable guidance and adjustable movement of the components in the processing chamber 4, and a plurality of supporting arms 52 are arranged in a circular array between the top of the lower pressure plate 51 and the bottom of the supporting top plate 53. The supporting arms 52 are connected to form a rigid frame structure, which effectively disperses and bears the pressure of the plastic material, ensuring that the heating space can be evenly adjusted according to needs. The first driving device 54 is installed on the top of the processing chamber 4, and its output end is fixedly connected to the top of the supporting top plate 53. The supporting top plate 53 and the associated lower pressure plate 51 are driven up and down by the first driving device 54 to realize precise spatial adjustment of the heating area.

[0035] Specifically, the first drive device 54 drives the support top plate 53 to move up and down, driving the lower pressure plate 51 connected by the support arm 52 to rise and fall synchronously, so that the effective space of the heating area can be adjusted according to the feeding amount of waste plastic. The lower pressure plate 51 is slidably sleeved on the heating rod 7, and its travel is limited by the limit sleeve to ensure the stability and safety of the structure. The support rod 31 at the top of the processing base 3 and the feed hopper 32 fixedly connected to the top of the outer wall of the processing chamber 4 together form a stable feeding channel to ensure that the plastic enters the processing chamber 4 evenly. By adjusting the position of the lower pressure plate 51, the device effectively compresses or expands the heating space, preventing the heating space from being too large, resulting in heat energy dispersion and local overheating, and also avoiding the problem of insufficient heating due to the space being too small to cover all the plastics, thereby improving the efficiency of heat energy utilization and the uniformity of plastic melting, solving the problems of fixed heating area space, low heating efficiency and uneven plastic melting in the prior art, and ensuring the stability of the waste plastic recycling process and the quality of the recycled materials.

[0036] Furthermore, if Figure 1-Figure 5 As shown, the stirring assembly 8 includes a second driving device 81, a driving rod 82 and a stirring arm 83, wherein the second driving device 81 is installed on the top of the lower pressure plate 51, one end of the driving rod 82 passes through the bottom of the lower pressure plate 51 and is fixedly connected to the output end of the second driving device 81, and multiple stirring arms 83 are symmetrically fixed side by side on the outer wall of the driving rod 82.

[0037] Furthermore, a support head 11 is provided between the top of the support base 1 and the bottom of the processing base 3, and they are connected through the support head 11. The outer wall of the collecting bin 2 is fixedly connected with a discharge nozzle 21, and a valve body is installed on the discharge nozzle 21. The bottom of the driving rod 82 is a conical structure.

[0038] It should be noted that the second drive device 81 described in this embodiment is installed on the top of the lower pressure plate 51, and its output end is fixedly connected to the drive rod 82 that passes through the bottom of the lower pressure plate 51 to achieve stable rotation of the drive rod 82. The bottom of the drive rod 82 adopts a conical structure design to improve the coordination with the lower pressure plate 51 and the internal plastic melt, and promote the uniformity and thoroughness of the stirring effect. Multiple stirring arms 83 are symmetrically fixed side by side along the outer wall of the drive rod 82 to ensure that the stirring covers the entire heating space and avoids local accumulation or dead corners of the plastic material during the heating process. The top of the support base 1 and the bottom of the processing base 3 are firmly connected by the support head 11, which enhances the structural rigidity and vibration resistance of the overall device and ensures the stable operation of the processing process. A discharge nozzle 21 is fixed on the outer wall of the collection bin 2, and is equipped with a valve body to achieve orderly discharge and control of the molten plastic to prevent overflow or blockage of the molten material. This design promotes the uniformity and fluidity of plastic melting through the coordinated cooperation of efficient stirring and structural support, improves processing efficiency and finished product quality, while achieving precise control of the molten material and optimizing the safety and stability of the overall recycling process. The second drive device 81 is a drive motor.

[0039] Specifically, the second drive device 81 is a drive motor, which is installed on the top of the lower pressure plate 51 and is fixedly connected to the drive rod 82 that passes through the bottom of the lower pressure plate 51 through its output end, so as to realize the stable rotation of the drive rod 82. The bottom of the drive rod 82 adopts a conical structure design to enhance the fit with the lower pressure plate 51 and the plastic melt, and promote the uniform stirring and thorough mixing of the stirring arm 83 in the heating space. Multiple stirring arms 83 are symmetrically arranged along the outer wall of the drive rod 82, covering the entire heating area, preventing local accumulation and temperature unevenness generated during the plastic melting process, and ensuring the uniformity and fluidity of the plastic melting. The top of the support base 1 is firmly connected to the bottom of the processing base 3 through the support head 11, enhancing the rigidity and vibration resistance of the overall structure of the device, and ensuring the stability and durability of the equipment operation. The outer wall of the collecting bin 2 is provided with a discharge nozzle 21 and is equipped with a valve body to realize the orderly discharge and flow control of the molten plastic, and prevent the molten material from overflowing or clogging during the discharge process. The design of the stirring component 8 achieves sufficient mixing and uniform heat energy transfer in the molten state of the plastic through efficient mechanical stirring combined with reasonable structural support, effectively avoiding the problems of low thermal efficiency and uneven melting caused by fixed heating space, and solving the problems of fixed heating area space, dispersed heat energy and insufficient heating in the background technology, significantly improving the thermal utilization rate and product quality stability of the waste plastic recycling process.

[0040] The working principle of the present invention is as follows:

[0041] Waste plastics enter the processing bin 4 from the upper feed hopper 32. The supporting bottom plate 6 supports the heating rod 7 and is in close contact with it, continuously providing stable heat energy to the plastic, allowing it to melt efficiently. The space adjustment component 5 realizes dynamic adjustment of the heating space through the cylinder-driven lower pressure plate 51 and the supporting top plate 53 in conjunction with the support arm 52, adapting to different feed amounts, avoiding the problem of heat dispersion caused by excessive heating space or insufficient heating caused by excessive heating space, and improving heating efficiency and melting uniformity. The stirring component 8 is composed of a driving rod 82 with multiple stirring arms 83 driven by a second driving device 81, which passes through the lower pressure plate 51 and stirs evenly along the heating space to prevent local accumulation and uneven temperature of the plastic, and promote sufficient mixing and fluidity of the melt.

Through the synergistic effect of spatially adjustable heating areas and efficient stirring, this device solves the problems of fixed heating areas, low thermal energy utilization and uneven melting in traditional waste plastic recycling. It significantly improves heating efficiency, melting quality and equipment adaptability, and ensures the stability of the recycling process and the excellent quality of recycled plastics.
