A separating cone plate 39 is rotatably engaged at the bottom of the inner end surface of the fixed cylinder 37, and a conical filter screen 35 is rotatably engaged at the inner end surface of the fixed cylinder 37 near the middle. A coupling groove is provided on the top of the conical filter screen 35 and the separating cone plate 39, and the coupling groove can be slidably engaged with the transmission slide shaft 276. The coupling groove can provide sufficient guiding basis for the up and down displacement of the transmission slide shaft 276 while the transmission is performed by the transmission slide shaft 276. Six groups of material guide ports 38 are equidistantly provided on the side end surface of the fixed cylinder 37 facing the separating cone plate 39, and six groups of material guide square tubes 36 are equidistantly provided on the side end surface of the fixed cylinder 37 facing the conical filter screen 35.

[0033] like Fig.14 and Fig.15The material guiding device 4 includes an extruding barrel 41, and four groups of pressed sliding grooves 42 are equidistantly provided on the inner end surface of the extruding barrel 41, and six groups of material discharge square tubes 43 are equidistantly provided on the side end surface of the extruding barrel 41 near the bottom.

[0034] A limiting slider is fixedly set at the bottom of the guide card plate 222, and the cross-sections of the limiting slider and the guide slide groove 21 are both in an inverted T-shape. The guide card plate 222 is adapted to the guide slide groove 21 through the limiting slider and then slidably connected to the upper end surface of the fixed base 26. The inverted T-shaped guide slide groove 21 and the limiting slider can effectively improve the stability of the subsequent sliding displacement of the limiting device 22 on the upper part of the fixed base 26.

[0035] The connecting turntable 234 is adapted to the fixed inclined groove 223 through the limiting sliding shaft 237, thereby driving the guide card plate 222 to slide forward and backward, and the transmission rack 224 is meshed and connected with the transmission gear 29. When the reduction motor 232 drives the limiting sliding shaft 237 to rotate in a circle through the connecting turntable 234, the limiting sliding shaft 237 can be limited by the sliding with the fixed inclined groove 223, thereby driving the guide card plate 222 to move forward and backward on the upper part of the fixed base 26, and then the transmission rack 224 is simultaneously connected to the transmission gear 29. The step drives the transmission gear 29 to engage and rotate, which can drive the transmission slide shaft 276 to rotate and move up and down at the same time, thereby improving the transmission efficiency. The fixed inclined groove 223 is slidably connected with the guide slide shaft 241, and the fixed swivel seat 242 is rotatably connected with the connecting rotary head 271. The fixed swivel seat 242 can limit the transmission slide shaft 276 through the connecting rotary head 271, which can not only provide sufficient limiting basis for the rotation of the transmission slide shaft 276, but also facilitate the transmission slide shaft 276 to move up and down.

[0036] The pressing guide plate 272 is adapted to the pressing groove 42 through the fixed slider 274 and then slidably engaged in the inside of the extrusion barrel 41. The spiral arch knife 273 slides through the inside of the guide tube 44, and the spiral arch knife 273 does not contact the inner wall of the guide tube 44. The pressing groove 42 can provide sufficient guiding basis for the up and down displacement of the pressing guide plate 272 through the fixed slider 274. At the same time, when the pressing guide plate 272 slides to the bottom of the extrusion barrel 41, the spiral arch knife 273 can rotate at high speed inside the guide tube 44 to improve the feeding efficiency.

[0037] Working principle: before use, the user can connect the external feed conduit with the feed pipe at the rear part of the mixing tank 310 near the top, so as to facilitate the subsequent introduction of the raw materials into the mixing tank 310 in a circular manner. Before processing the power pipe, the staff can start the reduction motor 232 through the external control device. At this time, the reduction motor 232 can drive the connecting turntable 234 to rotate. When the connecting turntable 234 rotates, it can synchronously drive the ball slide 231 and the limit slide shaft 237 to rotate in a circle. When the limit slide shaft 237 rotates in a circle, the limit slide shaft 237 can limit the sliding position with the guide slide rail 221, and then cyclically drive the guide card plate 222 to move forward and backward on the upper part of the fixed base 26. When the above-mentioned guide card plate 222 moves forward and backward, the guide card plate 222 can drive the pressing device 27 to rotate at high speed through the meshing of the transmission rack 224 at the bottom with the transmission gear 29; First, the pressing device 27 can drive the multiple groups of mixing blades 31 to rotate at high speed through the fixed shaft sleeve 32, so that the mixing blades 31 can further mix and crush the raw materials. The crushed raw materials are directly introduced into the fixed cylinder 37 through the four groups of discharge pipes 311. At this time, the mixed and crushed raw materials can fall to the upper part of the conical filter 35. When the pressing device 27 is rotating, it can synchronously drive the conical filter 35 and the partitioning conical plate 39 to rotate, so that the conical filter 35 can rotate and screen the raw materials falling from the discharge pipe 311. At the same time, the raw materials that have not been screened can be guided out through the guide square tube 36, which is convenient for subsequent re-introduction into the mixing tank 310 for secondary crushing and mixing. The screened raw materials can fall to the upper part of the partitioning conical plate 39. Under the rotation guidance of the partitioning conical plate 39, they can be introduced into the discharge square tube 43 through the guide port 38. The six groups of discharge square tubes 43 can directly introduce the screened raw materials into the extrusion barrel 41. When the raw material is introduced into the extrusion barrel 41, the material guiding operation is completed. When the raw material is pressed and arched to be fed, the above-mentioned guide card plate 222 can be limited by the sliding of the internal fixed inclined groove 223 and the guide slide shaft 241 during the forward and backward cyclic displacement, thereby driving the support card plate 244 and the limiting slide seat 243 to move up and down stably inside the guide slide seat 25. At this time, the support card plate 244 can drive the connecting head 271 and the transmission slide shaft 276 to move up and down through the fixed rotating seat 242, and the transmission slide shaft 276 can drive the second alignment rotating seat 275 and the pressing guide plate 272 to move vertically up and down inside the extrusion barrel 41. When the pressing guide plate 272 and the spiral arch knife 273 are at the uppermost At this time, the six groups of feeding square tubes 43 can quickly guide the raw materials into the extrusion barrel 41 until the standard position, and then the pressing guide plate 272 moves down to press and feed the raw materials. When the raw materials inside the guide tube 44 are gradually solidified under the pressing action, the spiral arch knife 273 at the bottom of the pressing guide plate 272 can rotate synchronously with the transmission slide shaft 276 at high speed, and at the same time, it can crush and rotate the pressed materials at high speed with the pressing guide plate 272, and then when the pressing guide plate 272 presses and feeds the raw materials, it can simultaneously arch the raw materials to prevent the solidification of the raw materials from blocking the feed port on the upper part of the PVC basic module 5, effectively improving the feeding efficiency of the equipment, and then improving the efficiency of the equipment in the foundation of PVC power pipes.
