Its technical points are: it includes at least two groups of outer shells, a first stirring unit for stirring raw materials is arranged in the outer shell, a metering pump is connected to the discharge port of the outer shell, the metering pump is connected to a mixing nozzle, an inner shell is also arranged in the outer shell, a first heating unit for heating the raw materials in the inner shell is arranged between the outer shell and the inner shell, a second heating unit for heating the raw materials at the discharge port is also arranged at the discharge port of the outer shell, the first heating unit is spirally wound on the outer wall of the inner shell, and the second heating unit is spirally arranged inside the feed port; the temperature control of the utility model is convenient, and the foaming quality of the utility model is high.

[0003] The above patent drives the filter to vibrate through the second stirring unit and the vibration motor to stir and mix the liquid raw materials entering the container. Since the vibration motor is installed inside the container, it will be affected by the high temperature and humid environment of the raw material foaming process, so it is easy to be damaged and has low practicality. In addition, the liquid raw material is easy to leak downward through the stirring shaft and drip onto the transmission housing and the stirring motor, thereby causing transmission instability and affecting work efficiency. Utility Model Content

[0004] The utility model aims to provide a foaming device for producing foam plastic products, which has the advantages of being convenient for vibrating and filtering the liquid raw materials of the foam plastics and preventing the liquid raw materials of the foam plastics from leaking downwards, thereby improving the transmission stability of the motor.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a foaming device for producing foam plastic products, including a tank body, the top of the tank body is fixedly connected to a barrel body, the top and bottom of the inner cavity of the barrel body are respectively rotatably connected to a first stirring frame and a third stirring frame, a first motor is installed on one side of the outer side of the barrel body, a second motor is installed on the bottom of the tank body, the inside of the tank body is rotatably connected to the second stirring frame, the output end of the first motor and the top of the third stirring frame are fixedly connected to mutually meshing bevel gears, the top of the third stirring frame and the output end of the second motor are fixedly connected to a turntable, the surface of the turntable is provided with a sliding cover that is partially slidably connected to the inside of the tank body and the barrel body, and magnet blocks that are magnetically connected to each other are fixedly connected between the turntable and the sliding cover.

[0006] By adopting the above technical scheme, the sealing between the sliding cover and the tank body and the barrel body when the sliding cover rotates can prevent the liquid raw materials from dripping directly into the interior. At the same time, even if a small amount of liquid raw materials penetrates into the interior, it is difficult to overcome gravity and continue to leak upward. When the internal material is discharged, the small amount of liquid raw materials that penetrate will also automatically slide down and leak out due to gravity, thereby effectively avoiding the leakage of liquid raw materials and improving practicality; when the third stirring frame rotates to stir the liquid raw materials, the push rod is driven to rotate inside the special-shaped groove, thereby synchronously driving the shaking plate to shake left and right on the top of the tank body, and at the same time, the spring is used to reciprocate and rebound on both sides of the shaking plate, thereby increasing the shaking frequency of the shaking plate, improving the filtering effect, and ensuring working stability.

[0007] The utility model is further configured as follows: a shaking plate is slidably connected to the top of the tank body cavity, both ends of the shaking plate are fixedly connected to springs fixedly connected to the tank body, both ends of the shaking plate pass through positioning rods slidably connected to the tank body, a special-shaped groove is provided inside the shaking plate, a push rod slidably connected to the special-shaped groove is fixedly connected to the bottom of the third stirring frame, and filter screens fixedly connected to the shaking plate are provided on both sides of the outside of the special-shaped groove.

[0008] By adopting the above technical solution, when the liquid raw material is stirred by rotating the third stirring frame, the push rod is driven to rotate inside the special-shaped groove, thereby synchronously driving the shaking plate to shake left and right on the top of the tank body, thereby improving the filtering effect and ensuring working stability.

[0009] The utility model is further configured as follows: a ball bearing which is rotatably connected to the tank body and the barrel body respectively and is slidably connected to the interior of the sliding cover, and a sealing ring which is bonded to the sliding cover is arranged at the bottom of the ball bearing.

[0010] By adopting the above technical solution, the friction of the sliding cover rotating on the outer surface of the turntable is reduced, and at the same time the sealing performance is improved to reduce liquid penetration.

[0011] The utility model is further configured as follows: a heat dissipation net is fixedly installed on one end of the outside of the tank body and the barrel body, respectively, close to the first motor and the second motor.

[0012] By adopting the above technical solution, the first motor and the second motor can be ventilated and cooled, thereby improving working stability.

[0013] The utility model is further configured as follows: one side of the top of the tank body is fixedly connected with a ventilation pipe.

[0014] The above technical solution facilitates the input of gas into the tank body, thereby causing the liquid plastic raw material to foam and generate foam.

[0015] The utility model is further configured as follows: a water injection cavity is provided inside the inner wall of the tank body, and valves are installed on one side of the bottom of the top of the water injection cavity.

[0016] By adopting the above technical solution, it is convenient to inject hot water or cold water into the water injection cavity through the valve, thereby heating and cooling the liquid plastic raw material inside the tank body to ensure the foaming effect.

[0017] The utility model is further configured as follows: a temperature conducting plate used in conjunction with the water injection cavity groove is fixedly connected to the surface of the inner wall of the tank body.

[0018] By adopting the above technical solution, it is convenient to conduct the heat exchange of the water source inside the water injection cavity through the temperature conduction plate, thereby improving the effect of heating and cooling the liquid plastic raw material.

[0019] The utility model is further configured as follows: a feeding port is provided on the top of the barrel body, and a discharge valve is fixedly connected to one side of the bottom of the tank body.

[0020] By adopting the above technical solution, liquid raw materials can be conveniently added into the barrel body through the feeding port, and the manufactured foam plastics can be discharged from the tank body through the discharge valve.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. The sealing between the sliding cover and the tank body and the barrel body when the sliding cover rotates can prevent the liquid raw materials from dripping directly into the interior. At the same time, even if a small amount of liquid raw materials penetrates into the interior, it is difficult to overcome gravity and continue to leak upward. When the internal materials are discharged, the small amount of liquid raw materials that have penetrated will also automatically slide down and leak out under the influence of gravity, thereby effectively avoiding the phenomenon of liquid raw material leakage and improving practicality;

[0023] 2. When the liquid raw materials are stirred by rotating the third stirring frame, the push rod is driven to rotate inside the special-shaped groove, thereby synchronously driving the shaking plate to shake left and right on the top of the tank body. At the same time, the spring is used to reciprocate and rebound on both sides of the shaking plate, thereby increasing the shaking frequency of the shaking plate, improving the filtering effect and ensuring working stability.
