All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-6, a mixer capable of preventing rubber from being scorched comprises a mixing box 1, wherein the mixing box 1 is made of stainless steel, which can effectively prevent equipment from being corroded, greatly prolongs the service life of the equipment, reduces the production cost, and plays an indispensable role in enterprises, extrusion 2 is arranged inside the mixing box 1, a supporting rod 3 is rotatably connected inside the extrusion 2, a limit spring is arranged on the side surface of the supporting rod 3, a receiving wheel 4 is engaged and connected on the side surface of the supporting rod 3, a metal plate 5 is fixedly connected on the side surface of the supporting rod 3 and on the side far away from the receiving wheel 4, a conductive rod 6 is arranged on the side surface of the metal plate 5 far away from the mixing box 1, a conductive block 7 is inserted into the side surface of the conductive rod 6, a delay rod 8 is rotatably connected on the side of the conductive block 7 far away from the supporting rod 3, the delay rod 8 is engaged with a delay tube 9 in a direction close to the mixing box 1, therefore, when the metal plate 5 is reset, the metal plate is inserted between the conducting rods 6, the receiving wheel 4 cannot be rotated, the side surface of the delay rod 8 is meshed and connected with the delay tube 9, the mercury tube 10 is arranged inside the extrusion 2, the mercury plate 11 is connected inside the mercury tube 10 in a sliding manner, one side, close to the center, of the mercury plate 11 is fixedly connected with the extrusion rod 12, the surface of the extrusion rod 12 is provided with the one-way extrusion block 13, the one-way extrusion block 13 is clamped with the blocking rod 14 in the one-way direction to the direction close to the center to accumulate the extrusion force of the extrusion rod 12 on the water bag 15, the side surface of the one-way extrusion block 13 is provided with the blocking rod 14, the blocking rod 14 is made of stainless steel and can effectively prevent equipment from being corroded, the water bag 15 is arranged inside the extrusion 2, the supporting spring is arranged inside the water bag 15, the condenser is arranged inside the water bag 15 to keep the liquid water in the water bag 15 at a low temperature, the surface of the water bag 15 is fixedly connected with the hose 16, the hose 16 is communicated with the water guide groove 17, and the water guide groove 17 is formed in the extrusion 2.
The working principle is that when the raw rubber is mixed, the motor is started, the extrusion 2 rotates, the raw rubber is put into the extrusion 2, and when the additive is put into the extrusion 352, the mixing starts.
The temperature of the extrusion 2 is gradually increased along with the progress of mixing, heat is gradually transferred to the mercury in the mercury tube 10 inside the extrusion 2, so that the mercury is heated and expanded to extrude the mercury plate 11, however, as the unidirectional extrusion block 13 arranged on the surface of the extrusion rod 12 on the side surface of the mercury plate 11 is blocked by the blocking rod 14, the extrusion rod 12 does not move immediately, as the surface temperature of the extrusion 2 changes, when the temperature approaches the temperature of the scorching raw rubber, the unidirectional extrusion block 13 goes over the blocking rod 14, so that the extrusion rod 12 moves rapidly towards the center of the extrusion 2 to extrude the water sac 15, the water sac 15 is extruded to fill the liquid water inside the water sac 15 into the diversion groove 17 through the hose 16, as the condenser exists in the water sac 15, the temperature of the liquid water in the water sac 15 is far lower than the temperature of the extrusion 2, so that the temperature of the extrusion 2 is rapidly reduced after the liquid water enters the diversion groove 17, the temperature of the surface of the extrusion 2 is rapidly reduced, so that the extrusion 2 is automatically cooled before the surface temperature of the extrusion 2 reaches the degree of burning the crude rubber, and the crude rubber is prevented from being burnt.
