Rubber filter capable of quickly changing screen

Abstract

The invention relates to the technical field of rubber machinery, in particular to a rubber filter capable of quickly changing a screen. In order to solve the problem that an existing rubber filter capable of quickly changing the screen is easy to leak rubber when the screen is changed without shutdown, the invention adopts the scheme that the rubber filter is provided with a machine barrel internally provided with a screw rod, wherein a sliding seat is arranged at the opening part of the machine barrel and comprises a rear sliding seat and a front sliding seat; a pore plate capable of sliding left and right is clamped between the front sliding seat and the rear sliding seat; the pore plate is provided with two groups of glue passing group holes respectively corresponding to the opening part of the machine barrel after sliding; the rear end face of each group of glue passing group holes is provided with a filter screen for filtering glue extruded by the screw rod; when one group of glue passing group holes are positioned in the sliding seat, the other group of glue passing group holes are positioned outside; the rear sliding seat is provided with an inner sealing ring which is in contact with the inner side surface of the pore plate and is used for preventing the glue from overflowing; the front sliding seat is provided with an outer sealing ring which is in contact with the outer side surface of the pore plate and is used for preventing the glue from overflowing; first adjusting bolts which are used for pushing and pressing the pore plate to enable the pore plate to cling to the inner sealing ring are distributed on the front sliding seat; and second adjusting bolts which are used for pushing and pressing the outer sealing ring to enable the outer sealing ring to cling to the pore plate are also distributed on the front sliding seat.

Description

technical field [0001] The invention relates to the technical field of rubber machinery, in particular to a quick-change screen rubber filter machine. Background technique [0002] The rubber filter machine is a machine that uses the screw to push and transport the impurities in the rubber material or reclaimed rubber. The machine is mainly composed of a screw, a machine barrel, a rubber filter head and a transmission device. The rubber filter head is equipped with Orifice plate and filter screen. The orifice plate is used to support the filter screen and is the discharge port. The hole diameter is generally 4-8mm. The molten rubber is extruded by the screw, filtered through the filter screen of the machine head, and then discharged from the discharge port. [0003] During the working process of the rubber filter, the mesh of the filter screen will be blocked by impurity particles, and the filter screen needs to be replaced. The degree of impurity in the rubber material dete...
