Abstract

The invention belongs to the technical field of extruders, and particularly relates to silk-screen-free filter equipment and a self-seal cooling transmission device. The self-seal cooling transmissiondevice comprises a main shaft mechanism and a connecting flange. The main shaft mechanism comprises a transmission main shaft and a cooling shaft sleeve, and the transmission main shaft is divided into a spline shaft section, a self-seal shaft section and a transmission shaft section. The cooling shaft sleeve sleeves the self-seal shaft section and is provided with a cooling ring groove. The connecting flange sleeves the cooling shaft sleeve and is provided with two refrigerant through holes. The two refrigerant through holes communicate with the cooling ring groove, and the self-seal shaft section is provided with a reverse thread groove. When fused plastics enter the reverse thread groove, cooling media in the cooling ring groove cool the fused plastics, the state of the fused plasticsis converted into the solid state, the solid plastics can be pushed and extruded back into a filter box again under pushing of a reverse thread, the fused plastics can generate the lubricating effecton the cooling shaft sleeve and the self-seal shaft section, and friction losses between the cooling shaft sleeve and the self-seal shaft section are reduced.

Description

technical field [0001] The invention belongs to the technical field of extruders, and in particular relates to a filter without wire mesh and a self-sealing cooling transmission device. Background technique [0002] In the plastic production industry, it is common to install a non-wire mesh filter in the plastic extruder to filter out particulate impurities in the molten plastic. The working principle of the non-wire mesh filter is to drive the scraper to rotate through the transmission shaft connected with the motor and the reducer to scrape off the impurities on the filter plate of the non-wire mesh filter. Since plastic extrusion operations are generally carried out in high-temperature (250°C-270°C) and high-pressure (8MPa-30MPa) environments, it is difficult to use ordinary lubrication and sealing methods between the drive shaft and the shaft sleeve that fixes the drive shaft At present, graphite copper sleeves are usually used to cooperate with the transmission shaft t...
