Abstract
Description
Technical Field
[0001] The invention relates to the technical field of friction material mixing, and in particular to a friction material raw material mixing device. Background Art
[0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. The mixing (blending) process of friction material is to mix the various materials specified in the formula through corresponding mixing equipment to achieve a uniform effect. The mixing methods are mainly divided into two processes: wet method and dry method.
[0003] When wet mixing is used, since the bonding material used is a liquid or fluid, there may be dissolved gas or original bubbles in the liquid, such as dissolved air in water. When the liquid is subjected to violent stirring and shearing during high-speed stirring or dispersion, the dissolved gas will escape from the liquid to form bubbles, especially when using materials with high viscosity such as fluids, such as polymer adhesives (resins and rubbers), and bubbles will be generated when the two components are stirred together, which will affect the performance of the product.
[0004] Existing friction material raw material mixing devices do not consider how to quickly and effectively remove the bubbles generated during mixing. They all adopt static or additional measures to remove the bubbles, which increases the production process and the production cycle, thereby reducing the production and processing efficiency of the friction material.

[0007] Furthermore, the workbench includes a fixed plate, on which a motor and multiple groups of balls are provided. The multiple groups of balls are distributed in a circular array on the fixed plate, and the motor is located at the center of the multiple groups of balls. The multiple groups of balls are used to reduce the friction of the storage barrel during rotation.
[0008] Furthermore, a fixing sleeve is provided on the fixing plate, and the inner diameter of the fixing sleeve is larger than the outer diameter of the storage barrel, and a plurality of friction plates are movably mounted on the fixing sleeve.
[0009] Furthermore, a push plate is movably mounted on the friction plate, and an elastic member 1 is provided between the push plate and the friction plate, and the thickness of the push plate gradually increases from the top to the bottom.
[0010] Furthermore, a stirring rod is provided at the bottom of the exhaust plug, and the stirring rod is slidably connected to the toggle member, and two groups of symmetrically distributed fixing rods are provided at the bottom of the exhaust plug, and the fixing rod is used to cooperate with the annular guide platform when the toggle member rotates to push the exhaust plug up, thereby discharging its body from the one-way exhaust valve. The exhaust plug is reset with the cooperation of the second elastic member, and the gas in the bubble removal assembly is drawn into the exhaust pipe through the one-way air inlet valve.
[0011] Furthermore, the fixing rod is provided with a steel ball, and the annular guide platform is provided with a guide groove, and the guide groove and the steel ball cooperate to make the cooperation between the fixing rod and the annular guide platform more stable.
[0012] Furthermore, a plug plate is movably installed on the exhaust pipe, and the plug plate is an inverted L-shaped plate composed of a horizontal plate and a vertical plate, the horizontal plate of the plug plate is connected to the fixing rod, the vertical plate of the plug plate is inserted into the fixing sleeve and squeezes the push plate, and the vertical plate on the plug plate is provided with a guide slope cooperating with the push plate.
[0013] Furthermore, a rotating ring is rotatably mounted on the toggle member to abut against the second elastic member, and a limiting groove cooperating with the toggle member is provided on the storage barrel.
[0014] A mixing method of a friction material raw material mixing device is applied to the above-mentioned friction material raw material mixing device, and the mixing method comprises the following steps: S1, putting the raw materials to be mixed into a storage barrel, and placing the storage barrel on a fixed plate and connecting it to the driving end of the motor; S2, connecting the bubble removal component to the workbench so that the sealing cover covers the storage barrel and forms a seal with the fixed disk, placing the storage barrel in the sealed cavity, and at the same time, inserting the plug plate on the bubble removal component into the fixed sleeve to squeeze the friction plate against the outer wall of the storage barrel, and the stirring rod on the bubble removal component will extend into the storage barrel; S3, start the motor to drive the storage barrel to rotate, cooperate with the stirring rod to stir and mix the raw materials, and at the same time, the toggle member follows the rotation of the storage barrel to drive the annular guide platform and cooperate with the fixed rod and the second elastic member, and then intermittently push the exhaust plug.

The exhaust plug 223 is pushed intermittently by the reciprocating ring. When the exhaust plug 223 rises, the gas cannot be discharged from the one-way air inlet valve 222 after being squeezed, and the gas can only be discharged from the one-way exhaust valve 221.
