Description

Technical Field

[0001] This utility model relates to the technical field of pipe extrusion production equipment, and in particular to a PPS pipe extrusion production equipment. Background Technology

[0002] In the extrusion production of PPS pipes, due to the high hygroscopicity and easy degradation of PPS material at high temperatures, traditional equipment often faces problems such as insufficient drying of raw materials or uneven heating leading to pipe defects, insufficient feeding metering accuracy affecting extrusion stability, uneven or unstable clamping force during conveying causing pipe deformation and scratches, and low precision in fixed-length cutting. These problems make it difficult to meet the high-performance and high-precision production requirements of PPS pipes. Therefore, a production device that integrates efficient drying, precise feeding, stable conveying and precise cutting functions is needed to solve these technical pain points. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a PPS pipe extrusion production device that solves the technical problems in key links such as raw material pretreatment, feeding stability, molding and conveying accuracy and fixed length cutting in PPS pipe production, thereby improving production efficiency and product quality stability.

[0004] This utility model also provides a PPS pipe extrusion production device as described above, with the following advantages: After the raw material is put into the drying silo, hot air is directionally sprayed out from the jet nozzle through the air inlet pipe. At the same time, the drive motor drives the stirring plate to stir the raw material to ensure that the material is heated evenly and reaches the preset dryness. When the raw material in the silo accumulates to the set threshold, it is quantitatively conveyed to the extruder through the metering hopper. After being melted and plasticized, it is extruded into pipes by the die head. Subsequently, the drive motor drives the bidirectional lead screw to rotate, which drives the conveying rollers on the support frames to achieve synchronous clamping action and position and convey the formed pipe. When the output length of the pipe reaches the preset value, the electric push rod drives the cutting wheel to move down and cut the pipe after passing through the gap of the conveying rollers, completing the fixed-length cutting of the pipe.

[0005] This utility model also provides a PPS pipe extrusion production device, the exclusive content of which includes: a support plate, a support column fixedly connected to the upper surface of the support plate, a base plate fixedly connected to the upper end of the support column, an extruder fixedly connected to the upper surface of the base plate, a metering hopper fixedly connected to the upper surface of the extruder, a drying hopper fixedly connected to the upper surface of the metering hopper, an air inlet pipe fixedly connected to the outer surface of the drying hopper, a jet nozzle fixedly connected to the inner surface of the drying hopper, the jet nozzle communicating with the air inlet pipe, a stirring plate rotatably connected to the inner surface of the drying hopper, a motor fixedly connected to the outer surface of the drying hopper, the stirring plate being driven by the motor, and an extruder head die fixedly connected to the output end of the extruder.

A cutting wheel is rotatably connected to the inner surface of the bracket. A third motor is fixedly connected to the outer surface of the bracket, and the cutting wheel is driven by the third motor. After the raw material is put into the drying silo, hot air is directionally sprayed out from the jet head through the air inlet pipe. At the same time, the first motor drives the stirring plate to stir the raw material to ensure that the material is heated evenly and reaches the preset dryness. When the raw material in the hopper accumulates to a set threshold, it is quantitatively conveyed to the extruder via a metering hopper. After being melted and plasticized, it is extruded into a pipe through the die head. Subsequently, drive motor two drives the bidirectional lead screw to rotate, which in turn drives the conveyor rollers one and two on the support frames one and two to perform synchronous clamping action, positioning and conveying the formed pipe. When the output length of the pipe reaches the preset value, the electric push rod drives the cutting wheel to descend and cut the pipe through the gap of the conveyor rollers, completing the fixed-length cutting of the pipe.

[0007] According to the present invention, a PPS pipe extrusion production device is provided, wherein the stirring plate has a square structure and a through-hole is provided on the outer surface of the stirring plate.

[0008] According to the present invention, a PPS pipe extrusion production device is provided, wherein the cutting wheel is a flat disc shape and the edge of the cutting wheel is provided with serrations. The flat disc design is adapted to the pipe cutting requirements, and the serrated edge enhances the cutting sharpness and ensures a flat cut.

The opposite threads can drive the relevant components to move synchronously in both directions, so as to achieve precise clamping of the pipe.

[0010] According to the present invention, a PPS pipe extrusion production device has a conical transition structure for the die head, which is made of stainless steel. The conical transition facilitates the smooth extrusion of raw materials.

[0011] According to the present invention, a PPS pipe extrusion production device is provided, wherein the first conveyor roller is a cylindrical structure and the outer surface of the first conveyor roller is provided with texture.

[0012] According to the present invention, in a PPS pipe extrusion production device, the second conveyor roller is a cylindrical structure with textured surfaces on its outer surface. The cylindrical structure is adapted to pipe conveying, and the textured surfaces increase friction to prevent slippage and deviation during pipe conveying.

[0013] Beneficial effects: After the raw materials are fed into the drying silo, hot air is directionally sprayed out from the jet nozzle through the air inlet pipe. Simultaneously, drive motor one drives the stirring plate to stir the raw materials, ensuring uniform heating and achieving the preset dryness. When the raw materials in the silo accumulate to the set threshold, they are quantitatively conveyed to the extruder through the metering hopper. After melting and plasticizing, they are extruded into pipes through the die head. Subsequently, drive motor two drives the bidirectional lead screw to rotate, causing the conveyor rollers on support frames one and two to synchronously clamp and position the formed pipes. When the pipe output length reaches the preset value, the electric push rod drives the cutting wheel to descend through the gap of the conveyor rollers and cut the pipe, completing the fixed-length cutting of the pipe.
