Internal mixer with dust-sucking and cooling device

Abstract

The invention discloses an internal mixer with a dust-sucking and cooling device. The internal mixer comprises an internal mixer body; a feeding port is formed in the outer wall of one side of the internal mixer body; a feeding hopper and a mixing chamber are arranged in the internal mixer body; the feeding hopper is positioned above the mixing chamber; an upper top bolt is arranged in the middleposition of the feeding hopper; the internal mixer is provided with a second motor, a screw rod, a second guide rod, a fixed base, a driving gear, a driven gear, a screw rod sleeve, a water pump, a dust-sucking pipeline, a centripetal annular spray head and a side wall; during unloading, a PLC controller controls a first motor to start to work, the first motor drives the driving gear through a rotating shaft to rotate, the driving gear is engaged with the driven gear, the driven gear drives the screw rod sleeve to rotate, and the screw rod sleeve is screwed with the screw rod when rotating, sothat the aim of ascending the screw rod is fulfilled, and the second guide rod drives the upper top bolt to move upwards when the screw rod ascends until one end of the second guide rod is contactedwith the screw rod sleeve; the upper top bolt is started in the unloading process, so that the discharging pressure of a lower top bolt can be reduced; in addition, when an adhesive material is cooled, dust is removed and the removed dust is fused into water for cooling, so that the processes are reduced and environmental friendliness is achieved.

Description

technical field [0001] The invention belongs to the technical field of internal mixers, and in particular relates to an internal mixer with a dust suction cooling device. Background technique [0002] Closed rubber mixing machine is referred to as internal mixer, also known as kneader, which is mainly used for plasticizing and mixing of rubber. Internal mixer is a kind of rotor with a pair of specific shapes and relative rotation. The temperature and pressure can be adjusted. It is a machine for plasticizing and kneading polymer materials intermittently in a closed state. It is mainly composed of a mixing chamber, a rotor, a rotor sealing device, a feeding and pressing device, a discharging device, a transmission device and a machine base. [0003] However, the discharge quality of the existing internal mixer during the discharge process is poor, and it is easy to damage the rubber material due to the excessive pressure of the top bolt and the unfixed position when moving. ...

AI Technical Summary

Problems solved by technology

[0003] However, the discharge quality of the existing internal mixer during the discharge process is poor, and it is easy to damage the rubber material due to the excessive pressure of the top bolt and the unfixed position when moving. The device drives the unloading door to open to realize unloading, but at the moment when unloading starts, the lower jacking bolt is under greater pressure, which is likely to cause damage to the unloading device, and when the unloading door is closed after unloading, it is easy to be unlocked and discharge in advance. However, when the material is unloaded, the temperature is very high and there is a lot of dust attached, which will make the subsequent transportation inconvenient, and the dust will also pollute the environment. The conventional dust collection and cooling methods are complicated and inefficient.
