Problems solved by technology
[0003] Existing extruders on the market use fixed perforated plates, and the plasticized raw materials extruded by the extruder are all helical. There is a certain bias flow and uneven pressure for subsequent molding. For example, the side seam drip irrigation belt is easy to drift when the mold wheel is formed, resulting in uneven pressure and different pipe diameters; Due to the spiral discharge, each dripper will be offset, which will have a great impact on the subsequent drilling; hard tubes and hoses will cause uneven wall thickness due to bias flow

Embodiment 1
[0013] Refer to attached figure 1 , Embodiment 1: A kind of rotating perforated plate device comprises perforated plate 1, gear 3, reduction box 4 and motor 5, and perforated plate is provided with a plurality of through holes that run through two end faces, and the circumference of perforated plate is provided with gear structure , and meshed with the gear, the gear is fixed on the shaft head of the reduction box, and the reduction box is connected with the motor. When the extruder extrudes the spiral-shaped plasticized raw material, the spiral-shaped raw material passes through the counter-rotating perforated plate, changing the spiral motion into a straight line motion, reducing the bias flow and uneven pressure, and improving the yield.

The invention discloses a rotary porous plate device. The rotary porous plate device comprises a porous plate 1, gears 3, a reduction gearbox 4 and a motor 5, wherein a plurality of through holes penetrating through two end surfaces are arranged in the porous plate; a gear structure is arranged in the circumference of the porous plate, and engaged with the gears; the gears are fixed on a shaft head of the reduction gearbox; and the reduction gearbox is connected with the motor. Spiral plasticizing raw materials pass through the reversely-rotating porous plate while being extruded by an extruder, a helical motion is changed into a rectilinear motion, and the conditions of flow deflection and non-uniform pressure are reduced, thus the yield is increased.
Description
technical field [0001] The invention relates to a rotating perforated plate device, which is especially suitable for the field of extruder molding production. Background technique [0002] There are two types of perforated plates used in various equipment: one is that there are many through holes between the two end faces of the cylinder, which is mainly used for equipment with high pressure such as extruders, and the other is that there are many through holes on the circumference of the cylinder. There are multiple through holes, most filters and other devices with low pressure. [0003] Existing extruders on the market use fixed perforated plates, and the plasticized raw materials extruded by the extruder are all helical. There is a certain bias flow and uneven pressure for subsequent molding. For example, the side seam drip irrigation belt is easy to drift when the mold wheel is formed, resulting in uneven pressure and different pipe diameters; Due to the spiral dischar...
