[0015] The following will be combined with the accompanying drawings of the present invention to clearly and completely describe the technical solution of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0016] according to Figure 1 、 Figure 2 As shown, a high-efficiency biodegradable material extrusion molding device includes: an extrusion barrel 1, which is a longitudinally arranged cylindrical structure with a feed port 2 at the top and a temperature-regulating jacket on the outer wall. A screw mechanism is provided inside the extrusion barrel 1; an extrusion die 3, which is arranged at the bottom of the extrusion barrel 1 and is connected to the discharge end of the extrusion barrel 1 through a control valve 4. A cutting device 5 is provided at the bottom of the extrusion die 3; a first temperature sensor 6, which is fixedly arranged on the wall in the middle of the extrusion barrel 1; and a controller 7. The temperature-regulating jacket, the first temperature sensor 6, the screw mechanism, the control valve 4, and the cutting device 5 are electrically connected to the controller 7 respectively. The screw mechanism includes an extrusion screw 8 longitudinally arranged in the extrusion barrel 1 and a drive motor 9 arranged at the top of the feed port 2 via a bracket. The extrusion screw 8 is connected to the output shaft of the drive motor 9, and the drive motor 9 is electrically connected to the controller 7.
[0017] The temperature-regulating jacket includes a heating unit, which is composed of a jacket 10 sleeved on the outer wall of the extrusion barrel 1, and a heating layer 11 and a thermal insulation layer 12 disposed within the jacket 10. The heating layer 11 is an electric heating wire spirally wound around the outer wall of the extrusion barrel 1, and the electric heating wire is electrically connected to the controller 7. The temperature-regulating jacket also includes a cooling unit, which is located below the heating unit and is composed of a plurality of semiconductor cooling fins 13 attached to the outer wall of the extrusion barrel 1. Each of the semiconductor cooling fins 13 is electrically connected to the controller 7.
[0018] During operation, biodegradable raw material particles are fed into the extrusion barrel 1 through the feed port 2, and the production process is initiated by the controller 7. The heating unit then begins operating according to the instructions of the controller 7, while the first temperature sensor 6 simultaneously monitors the temperature changes within the extrusion barrel 1. When the set temperature is reached, the controller 7 activates the drive motor 9 to activate the extrusion screw 8, and simultaneously coordinates the opening of the control valve 4 and the operation of the cutting device 5, so that the biodegradable material is extruded, formed, and cut to complete the product. During this process, the temperature-regulating jacket precisely controls the material temperature during extrusion through the heating unit and cooling unit, ensuring that the material remains within the optimal processing temperature range during extrusion, avoiding degradation due to overheating or insufficient temperature.
[0019] The first temperature sensor 6 is located between the heating unit and the cooling unit. The first temperature sensor 6 in this position can accurately reflect the temperature of the material in the extruder 1, and once the material is detected to be overheated, the cooling unit can be used to adjust the temperature.
[0020] The extruder 1 further includes a second temperature sensor 14 , which is fixedly disposed on the inner wall of the bottom end of the extrusion barrel 1 , and is electrically connected to the controller 7 .
[0021] In this setting, the second temperature sensor 14 collects the temperature at the outlet end of the extruder 1, so as to accurately judge the actual temperature of the material in the molding stage and provide control parameters for the power adjustment of the cooling unit, thereby ensuring that the material can be cut smoothly after passing through the mold and the yield rate after cutting.
[0022] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
