Abstract
Provided is a sealing structure between a kneading chamber wall and a kneading shaft of a rubber kneading machine. The kneading shaft is connected into a kneading shaft hole in the kneading chamber wall in a rotating mode. A seal ring in the kneading shaft hole is located between the kneading shaft and the kneading chamber wall. The kneading shaft is sleeved with the seal ring. A seal ring pressing plate is arranged on the right side the kneading shaft hole and fixedly connected to the kneading chamber wall. The seal structure further comprises an oil injection device. An oil injection hole is formed in the portion, above the kneading shaft, of the pressing plate and communicated with the oil injection device through an oil pipe. The oil injection device is fixedly connected to the portion, above the kneading shaft, of the kneading chamber wall. The right side of the seal ring is opposite to the oil injection hole. Existing dry-type sealing is converted into wet type sealing; thin lubricating oil exists on the friction face all the time, and therefore the sealing is called wet-type sealing. Lubricating oil exists on the friction face all the time for lubrication, and therefore the phenomena that the seal ring is blocked and stuck are effectively eliminated, and the service life of the seal ring is prolonged.
Description
Technical field
The utility model relates to rubber kneading machine, particularly the kneading locular wall of rubber kneading machine and the sealing configuration of kneading between centers.
Background technique
Current, in kneading axis hole on the kneading locular wall of rubber kneading machine, be rotatably connected to kneading axle, be located at seal ring in kneading axis hole between kneading axle and kneading locular wall, seal ring set is on kneading axle, kneading axis hole right side is provided with seal ring compression plate, compression plate is fixedly connected on kneading locular wall, owing to there is no lubricant oil, therefore this sealing is called dry-type encapsulated.In the process of milled rubber powder, due to dry type friction for a long time between seal ring and kneading axle, in the situation that there is no oil lubrication, often there is obstruction, the stuck phenomenon of seal ring, rubber powder in kneading chamber can spill from the gap between kneading axle and seal ring, kneading locular wall and seal ring, compression plate and kneading axle, compression plate and kneading locular wall simultaneously, cause unnecessary waste, the rubber powder spilling is under the drive of kneading axle, after being dispersed in the middle of air, directly have influence on indoor environment.In the serious situation of seal wears, leak powder phenomenon more outstanding.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of kneading locular wall of rubber kneading machine and sealing configuration of kneading between centers of good seal performance.
The technical solution of the utility model completes like this, the kneading locular wall of rubber kneading machine and the sealing configuration of kneading between centers, be located in the kneading axis hole on kneading locular wall and be rotatably connected to kneading axle, be located at seal ring in kneading axis hole between kneading axle and kneading locular wall, seal ring set is on kneading axle, kneading axis hole right side is provided with seal ring compression plate, compression plate is fixedly connected on kneading locular wall, also include oil-filling device, the compression plate of kneading axle top is provided with tank filler sleeve, tank filler sleeve is communicated with by oil pipe with oil-filling device, oil-filling device is fixedly connected on the kneading locular wall of kneading axle top, seal ring right side is relative with tank filler sleeve.
Further preferably implement technological scheme, described oil-filling device is filler tank.
Further preferably implement technological scheme, described oil-filling device includes filler tank, gasoline pump, and tank filler sleeve is communicated with by oil pipe with gasoline pump oil outlet, and gasoline pump filler opening is communicated with by oil pipe with filler tank.
Further preferably implement technological scheme, described gasoline pump is self-service petrol pump.
Further preferably implement technological scheme, described seal ring is copper ring.
Technique effect of the present utility model is, by the original dry-type encapsulated wet-sealed that changes into, because rubbing surface has lubrication thin oil existence all the time, therefore this kind of sealing to be called to wet-sealed.Because rubbing surface has oil lubrication all the time, efficiently solve the obstruction of seal ring, stuck phenomenon, has also extended working life of seal ring.Fill in gap between kneading axle and seal ring, kneading axial wall and seal ring, compression plate and kneading axle, compression plate and kneading locular wall all the time lubricated oil, rubber powder in kneading chamber just can not run out from the gap between kneading axle and seal ring, kneading locular wall and seal ring, compression plate and kneading axle, compression plate and kneading locular wall, has effectively improved leakage powder and has leaked material problem.
