[0030] like Figure 1 and Figure 2As shown, the embodiment of the utility model provides a rubber raw material preheating mixing equipment for cable processing, including a body 1, the inner wall of the body 1 is provided with a movable groove 14, the inner wall of the movable groove 14 is rotatably connected with a turntable 4, the top of the turntable 4 is fixedly equipped with a motor 2, the output shaft of the motor 2 is fixedly sleeved with a straight pipe 11, the outer wall of the straight pipe 11 is provided with a feeding pipe 5, the bottom end of the straight pipe 11 is fixedly equipped with a hopper 12, the outer wall of the hopper 12 is provided with a discharge hole 13, the top of the body 1 is penetrated with a material injection port 3 until the inner wall of the body 1, the outer wall of the body 1 is fixedly equipped with a shell 6, the outer wall of the shell 6 is respectively penetrated with an air outlet pipe 7 and an air return pipe 8, the inner wall of the air return pipe 8 is provided with an annular groove 18, the inner wall of the annular groove 18 is fixedly equipped with a limit rod 19, the outer wall of the limit rod 19 is sleeved with a spring 22, the outer wall of the spring 22 is in contact with a movable ring 20, and the movable ring 2 0 is fixedly equipped with a connecting rod 21 on the outer wall, and a piston 17 is fixedly equipped at the end of the connecting rod 21, a fan 9 is fixedly equipped on the outer wall of the outer shell 6, an insulating tube 16 is fixedly equipped on the bottom of the inner wall of the outer shell 6, and a refrigerant tube 15 is wound around the outer wall of the insulating tube 16, and a discharge pipe 10 is provided at the bottom of the main body 1. Through the structure of the main body 1, the motor 2, the straight tube 11, the hopper 12, and the discharge hole 13, when the user mixes the raw rubber, carbon black and rubber additives through the device, the motor 2 drives the straight tube 11 to rotate, and at this time the user can put the rubber additives and carbon black into the hopper 12 through the feeding tube 5, and use the centrifugal force when the straight tube 11 rotates to make the rubber additives and carbon black be thrown out of the hopper 12, thereby increasing the mixing effect of the three, and at the same time cooperate with the stirring rod to further mix and stir the three, thereby improving the mixing effect of the device.

[0031] like Figure 1 and Figure 6 As shown, there are two connecting rods 21, and the limiting rod 19 and the connecting rod 21 are both made of galvanized iron metal. The outer wall of the piston 17 is slidably connected to the inner wall of the return air pipe 8. The galvanized iron metal has the characteristics of hardness and wear resistance, which can effectively ensure the limiting effect of the limiting rod 19 on the movable ring 20, and the connecting rod 21 can fix the piston 17 and connect the piston 17 with the movable ring 20, so as to utilize the expansion of high-temperature air to allow high-temperature air to enter the main body 1, thereby avoiding the movable ring 20 from shaking when the high-temperature air pushes the piston 17 to move, thereby achieving the effect of heat recovery and improving the energy utilization rate of the device.

[0032] like Figure 1 and Figure 2As shown, the interior of the shell 6 is connected to the interior of the main body 1 through the air outlet pipe 7 and the air return pipe 8, and the interior of the shell 6 is connected to the outside through the fan 9. Through the structure of the air outlet pipe 7 and the air return pipe 8, when the mixing inside the main body 1 is completed, the material is discharged through the discharge pipe 10, and the exhaust gas enters the shell 6 through the air outlet pipe 7. At this time, the inside of the shell 6 is filled with external cold air through the fan 9. Due to the insulating effect of the insulating pipe 16 and the heat conducting effect of the refrigerant pipe 15, the residual heat in the exhaust gas is heat-converted with the cold air. After the cold air heats up, the heat expansion pushes the piston 17 out of the return pipe 8, so that the heated air enters the main body 1, thereby achieving the effect of heat recovery.

[0033] like Figure 3 and Figure 5 As shown, the interior of the hopper 12 is connected to the interior of the main body 1 through the discharge hole 13, and the inner walls of the hopper 12 are filled with carbon black and rubber additives respectively. Through the set hopper 12 structure, the user can put the additives and carbon black into the hopper 12 through the feeding pipe 5. When the straight tube 11 rotates, it will drive the hopper 12 to rotate, and the centrifugal force will throw the additives and carbon black out, so that the two are mixed with the raw rubber, thereby improving the mixing effect of the device.

[0034] like Figure 1 and Figure 3 As shown, a heating rod is fixedly mounted on the inner wall of the main body 1, and a stirring rod is fixedly mounted on the outer wall of the straight tube 11. By setting the heating rod and stirring rod structure, the heating effect of the heating rod on the raw rubber, carbon black and rubber additive is utilized to ensure that the three are fully mixed, and then the stirring rod is used to drive the mixture to rotate, so that the three are further mixed.

[0035] like Figure 2 and Figure 3 As shown, the end of the feeding pipe 5 passes through the bottom of the turntable 4 to the top of the straight pipe 11, and a controller is fixedly installed on the outer wall of the main body 1, and the controller is electrically connected to the motor 2, the fan 9 and the heating rod respectively. A solenoid valve is provided on the inner wall of the isolation tube 16, and the solenoid valve is electrically connected to the controller. Through the set controller structure, the user can control the operating time and output frequency of the motor 2 through the controller, thereby realizing fully automatic start and stop operations, thereby improving the automation of the device.

[0036] The technical solution provided by the utility model is that after the user assembles the device, the raw rubber can be fed into the main body 1 from the injection port 3, and then the carbon black and rubber additives can be fed into the hopper 12 respectively through the feeding pipe 5, and then the straight pipe 11 and the hopper 12 can be rotated synchronously by controlling the operation of the motor 2. At this time, under the influence of centrifugal force, the carbon black and rubber additives are both thrown out, so that the three are fully mixed after melting. When the mixing operation is completed, the prepared rubber is discharged from the discharge pipe 10, and the exhaust gas enters the shell 6 through the exhaust pipe 7. At this time, the outside air can be drawn into the shell 6 through the fan 9, and the residual heat in the exhaust gas is conducted to the cold air through the heat transfer effect of the refrigerant pipe 15. When the cold air is heated and expands, it pushes the piston 17 to move and detach from the return air pipe 8, and finally enters the main body 1, and the exhaust gas after heat exhaust accumulates. Finally, the user can open the solenoid valve through the controller to discharge the exhaust gas to the outside of the shell 6.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.
