[0024] Working principle: When in use, first place the equipment box 1 at the designated position, the user puts the material into the hopper 102 through the feed tube 114, and the user operates the control button 101, so that the control button 101 controls the rotating motor 203 on the surface of the hopper 102 to work, and the mixing roller 202 is driven to rotate inside the hopper 102 under the action of the rotating motor 203. When the mixing roller 202 rotates, the mixing roller 202 drives the mixing rod 201 to rotate inside the hopper 102. Under the joint action of the mixing rod 201 and the mixing roller 202, the hopper 102 is rotated. 2 is mixed with the materials inside. When the mixing rod 201 rotates, the mixing rod 201 drives the scraper plate 204 to rotate inside the hopper 102. Under the action of the scraper plate 204, the materials adhering to the inner wall of the hopper 102 are scraped off, so that all the materials can enter the next step without causing material waste, so as to realize the function of fully mixing and stirring the materials by the co-extrusion equipment, so that when the co-extrusion equipment is used, the phenomenon of uneven mixing of materials can be avoided when the co-extrusion equipment is used to mix the materials, so that the co-extrusion equipment has a better mixing and stirring effect on the materials.

[0025] Subsequently, the material enters the interior of the equipment housing 1, and the user operates the control button 101, so that the control button 101 controls the driving motor 301 inside the equipment housing 1 to work, and the driving motor 301 drives the rotating shaft 302 to rotate inside the equipment housing 1, and when the rotating shaft 302 rotates, the rotating shaft 302 drives the reverse spiral mixer 3031 to rotate inside the equipment housing 1, and when the reverse spiral mixer 3031 rotates, the reverse spiral mixer 3031 drives the mixing rod 3033 to rotate inside the equipment housing 1, and under the action of the mixing rod 3033, the equipment housing is rotated. The material inside the device box 1 is more fully mixed and kneaded. Subsequently, when the reverse spiral mixer 3031 rotates, the reverse spiral mixer 3031 drives the shearing component 3032 to rotate inside the device box 1. Under the action of the shearing component 3032, the material with a larger volume inside the device box 1 is sheared, so that the material is more evenly mixed, so as to realize the function of shearing and dispersing the material by the co-extrusion equipment, so that the co-extrusion equipment can cut and cut the larger volume of material when in use, so that the co-extrusion equipment is more dispersed when unloading, which is convenient for subsequent operation and processing.

[0026] Subsequently, the clinker inside the equipment box 1 enters the low-speed cooling chamber 113 through the feed pipe.

Under the action of the water jacket body 402, a zone water jacket can be opened as needed. The cooling water enters the water tank 4033 inside the core shaft 4031, and then enters the empty groove inside the stirring blade 4032. When the motor body 115 rotates inside the equipment box 1, the motor body 115 drives the core shaft 4031 to rotate at the low-speed cooling chamber 113. The interior of the low-speed cooling chamber 113 rotates, and at the same time, the clinker in the low-speed cooling chamber 113 can be cooled by the cooling water in the water tank 4033 and the empty tank. Then, the user operates the control button 101, so that the control button 101 controls the induced draft fan 4034 on the inner wall of the low-speed cooling chamber 113 to work, and the induced draft fan 4034 sucks air into the interior of the low-speed cooling chamber 113. Since the core shaft 4031 and the stirring blade 4032 are hollow in design, the entire low-speed cooling chamber 113 can be cooled. The inner cavity is ventilated to accelerate the cooling of the clinker to realize the cooling and ventilation function of the co-extrusion equipment, so that the co-extrusion equipment can cool the material when it is used, and the co-extrusion equipment can automatically control the material to a certain temperature after cooling down before entering the next step of operation, so that the co-extrusion equipment has a better cooling effect on the material when it is used. Subsequently, the cooled clinker enters the interior of the extruder box 103, and the double extruder inside the extruder box 103 is controlled to work under the action of the power unit 112. Among them, the large angle is used to quickly squeeze out the gas in the material and can press the material out. Under the action of the five-roller auxiliary machine 110, it is convenient to control the tensile stability of the product, and products of different structures can be produced according to the requirements of different customers. The material is transported under the action of the roller 109, and the plate can be heated and cooled inside the oil temperature machine 106 and the temperature regulating box 107 to control its straightness. The derailment surface of the roller 109 is a large spherical arc surface, which means that a reverse arc is given in advance during cooling, and it is flat after cooling, and finally the use of the co-extrusion equipment is completed.
