The water inlet is connected to one of the cooling circulation ports 116 through a water inlet pipe 122. A water pump 123 is provided in series on the water inlet pipe 122. The water outlet is connected to the other cooling circulation port 116 through a drain pipe 121. A cooling fan bracket 118 is fixed to the side of the cooling heat exchange row 117. A cooling fan 119 is rotatably mounted on the cooling fan bracket 118. A gap is provided between the cooling fan 119 and the side of the cooling heat exchange row 117 to increase the air flow through the cooling heat exchange row 117. Two parallel conveyor pulleys 114 are rotatably mounted at the bottom of the inner wall of the cooling pool 110. The two conveyor pulleys 114 are connected by a conveyor belt 112. A support sliding plate 113 is slidably mounted on the top of the inner side of the conveyor belt 112 to support the upper half of the conveyor belt 112 to prevent the upper surface of the conveyor belt 112 from being concave. The support sliding plate 113 is fixed to the cooling pool 110. A conveyor drive pulley 115 is rotatably mounted on the outer wall of the cooling pool 110. The conveyor drive pulley 115 is fixed to one of the conveyor pulleys 114 via a rotating shaft, and the rotating shaft and the cooling pool 110 are rotatably sealed. The cooling heat exchange row 117 is fixed on the bottom support plate 129, and the gearbox 125 and the drive motor 128 are fixedly installed on the bottom support plate 129, wherein the input shaft of the gearbox 125 is fixedly matched with the output shaft of the drive motor 128, and the drive pulley 104 is rotatably installed at the end of the extrusion heating tube 101 away from the discharge nozzle 106, and the drive pulley 104 is fixedly matched with the extrusion screw 105 through a rotating shaft, and the drive pulley 104 is connected to the input shaft of the gearbox 125 or the output shaft of the drive motor 128 through a third transmission belt 126. The output shaft of the gearbox 125 is connected to the transmission drive pulley 115 and the cooling fan 119 through a first transmission belt 120, wherein the transmission drive pulley 115 also drives the water pump 123 to work through the second transmission belt 124.A top support platform 127 is fixed on the bottom support plate 129 via a plurality of vertically arranged support legs 130, wherein the extrusion heating tube 101 and the cooling pool 110 are fixedly mounted on the top support platform 127, and a support roller 111 for supporting the plastic rattan that has been cooled and formed is rotatably mounted on the inner wall of the cooling pool 110 at one end away from the discharge nozzle 106, and a funnel 102 is fixedly connected to the feeding tube 103.

[0022] The working principle of the plastic rattan extrusion molding equipment disclosed in the present invention is as follows: the required plastic granule raw material is poured into the funnel 102, and then enters the extrusion heating tube 101 through the feeding tube 103, and the heating wire embedded in the extrusion heating tube 101 is started, and the heating wire melts the plastic raw material, and then the driving motor 128 is started, and the output shaft of the driving motor 128 drives the driving pulley 104 to rotate through the third transmission belt 126, and the driving pulley 104 drives the extrusion screw 105 to rotate, and the extrusion screw 105 drives the melted plastic raw material and the unmelted plastic granules to move in the extrusion heating tube 101 toward the discharge nozzle 106, and then the melted plastic will The plastic rattan is formed by passing through the extrusion hole on the forming nozzle 109. The formed plastic rattan will fall into the cooling pool 110. Cooling water is provided in the cooling pool 110 to cool and shape the plastic rattan in a high-temperature soft state. In order to prevent the plastic rattan from being elongated due to its own gravity during the cooling process (after elongation, the quality of the plastic rattan will deteriorate due to the reduction in diameter), a rotating conveyor belt 112 is provided at the bottom of the cooling pool 110. The movement direction of the upper surface of the conveyor belt 112 will be the same as the movement direction of the plastic rattan. The two move synchronously, and one end of the cooled and shaped plastic rattan is connected to the traction mechanism for traction and winding of the formed plastic rattan.

[0023] During the cooling process of the plastic rattan, the temperature of the cooling water inside the cooling pool 110 will gradually increase, which will lead to a decrease in the cooling efficiency of the plastic rattan. Therefore, the high-temperature cooling water inside the cooling pool 110 is circulated through the cooling heat exchange row 117 through the water pump 123, and the high-temperature cooling water is reduced to a low-temperature state through the cooling heat exchange row 117. Specifically, the rotating cooling fan 119 will drive the external air into the cooling heat exchange row 117. In this process, since a gap is provided between the cooling fan 119 and the cooling heat exchange row 117, the flowing air driven by the rotation of the cooling fan 119 and the surrounding air at the gap position will flow with the flowing air. This is because the pressure inside the flowing air is lower than the external static air, so more air can enter the cooling heat exchange row 117, and the cooling heat exchange row 117 will heat the air around itself, thereby transferring its own heat to the air. At this time, the flowing air will blow away the air around the cooling heat exchange row 117, thereby improving the heat exchange efficiency between the cooling heat exchange row 117 and the air.

[0024] The output shaft of the driving motor 128 also drives the input shaft of the gearbox 125 to rotate, so the output shaft of the gearbox 125 drives the cooling fan 119 and the transmission drive pulley 115 to rotate through the first transmission belt 120, and the rotation of the transmission drive pulley 115 drives the water pump 123 to work through the second transmission belt 124, so that the cooling water inside the cooling pool 110 and the cooling water inside the heat exchange row 117 circulate. At the same time, the rotation of the transmission drive pulley 115 drives the transmission pulley 114 to rotate, and the rotation of the transmission pulley 114 drives the conveyor belt 112 to rotate.

[0025] If it is necessary to form plastic rattan strips with different cross-sectional shapes, it is only necessary to remove the original forming nozzle 109 from the discharge nozzle 106 and replace it.
