A splash plate 102 is fixed on the top of the cooling pool 101, a feeding hole 103 is fixed at the axis of the splash plate 102, and the bottom end of the feeding hole 103 is fixedly connected with the top end of the connecting pipe 107. A feeding spiral plate 131 is rotatably arranged between the conical base 113 and the conical outer sleeve 114, the bottom end of the feeding spiral plate 131 is fixedly matched with the transmission shaft 130 through the feeding spiral plate connecting seat 132, and a drop collection chamber 117 is fixedly connected at the bottom end of the conical outer sleeve 114, and a discharge pipe 118 is fixedly connected at the bottom end of the drop collection chamber 117, and the top end of the discharge pipe 118 is higher than the height of the water inside the cooling pool 101. A conveying screw 119 is rotatably installed in the discharge pipe 118, and the conveying screw 119 is driven by a discharge motor 120 fixed on the outside of the discharge pipe 118, wherein the conical sleeve 114 is fixed on the support leg 115, and an intermediate support platform 116 is fixedly installed on the support leg 115, and a planetary carrier 127 is rotatably installed on the intermediate support platform 116, and three planetary gears 128 are rotatably installed on the planetary carrier 127, and a central driving gear 124 is meshed at the middle position of the three planetary gears 128, and an outer ring gear plate 129 is meshed at the outer position of the three planetary gears 128, and the outer ring gear plate 129 is fixed to the bottom end of the transmission shaft 130.A driven pulley 123 is coaxially fixed on the planet carrier 127, and a control motor 121 is also fixedly mounted on the intermediate support platform 116. The output shaft of the control motor 121 is connected to the driven pulley 123 through a transmission belt 122. A toothed disc bracket 125 is fixedly mounted on the intermediate support platform 116, and a toothed disc 126 is rotatably mounted on the toothed disc bracket 125. The toothed disc 126 is fixed to the central driving gear 124 through a rotating shaft.

[0024] The working principle of a particle manufacturing device for toy processing disclosed by the present invention is as follows: plastic raw materials are fed into the feeding hole 103 (using a screw), and heating wires are provided in the connecting pipe 107 and the centrifugal extrusion tube 110 to melt the plastic. At this time, the plastic raw materials are melted into liquid by the heat. The toothed disc 126 is driven to rotate (in actual work, multiple devices are arranged in parallel to improve production efficiency. The toothed discs 126 in each device are synchronously driven by a chain, so only one motor is needed to drive all devices to work simultaneously). The rotation of the toothed disc 126 will drive the center drive gear 124 to rotate. The rotation of the center drive gear 124 will drive the outer ring gear plate 129 to rotate through the planetary gear 128. Under the premise that the rotation of the planetary carrier 127 is restricted, the rotation of the outer ring gear plate 129 will drive the transmission shaft 130 to rotate, and the transmission shaft 130 will drive the unloading spiral plate 131 and the bottom The thumbwheel plate 112 rotates, and the rotation of the bottom thumbwheel plate 112 drives the centrifugal extrusion tube 110 to rotate. The rotation of the centrifugal extrusion tube 110 causes the molten plastic liquid to rotate. At this time, the molten plastic liquid is moved toward the extrusion forming hole 111 by the action of centrifugal force. Since the plastic melt is squeezed by the centrifugal force, the plastic melt passes through the extrusion forming hole 111 to form long filaments, which enter the cooling water inside the cooling pool 101 to solidify quickly. At the same time, under the action of the cutting blade 106, the filamentary plastic strip can be quickly cut off to form multiple small segments. During the rotation of the bottom paddle plate 112, the impeller plate on the bottom paddle plate 112 will paddle the water inside the cooling pool 101 to rotate, so that the plastic particles (the cut small segments of plastic) falling into the water will rotate with it. At this time, the plastic particles will be moved to the bottom edge of the inner wall of the cooling pool 101 by the centrifugal force, and fall into the gap between the conical base 113 and the conical jacket 114 under the action of gravity. At this time, the rotating unloading spiral plate 131 will transmit the fallen plastic particles to the bottom of the conical jacket 114, so that the plastic particles enter the falling collection chamber 117, and under the action of gravity, the plastic particles fall onto the conveying screw 119, and the discharge motor 120 is started. The output shaft of the discharge motor 120 drives the conveying screw 119 to rotate (the conveying screw 119 and the toothed disc 126 can also be synchronously driven). The conveying screw 119 can convey the plastic to the top of the discharge pipe 118, and then discharge it to a designated position for subsequent drying treatment.

[0025] In order to ensure the independence of the work between each device as much as possible, the rotation state of the transmission shaft 130 can be controlled by controlling the rotation of the output shaft of the motor 121, thereby controlling the working state of the device. Specifically, the output shaft of the control motor 121 can control the rotation of the driven pulley 123 through the transmission belt 122, and the driven pulley 123 is fixed on the planetary carrier 127. The rotation state of the planetary carrier 127 will control the transmission ratio of the power transmitted from the central driving gear 124 to the outer ring gear plate 129. When the planetary carrier 127 is in a state without any restrictions, the power cannot be transmitted to the transmission shaft 130 through the toothed plate 126. On the contrary, when the planetary carrier 127 is restricted by the control motor 121, the magnitude of the restriction force can be controlled by the control motor 121. By controlling the direction and speed of the rotation of the planetary carrier 127, the rotation speed of the transmission shaft 130 can be controlled (under the premise that the rotation speed of the toothed plate 126 remains unchanged). In the transmission path between the output shaft of the control motor 121 and the driven pulley 123.
