Technical Field
The invention relates to the technical field of plastic pipe production, in particular to a small-diameter Teflon pipe extruder.
Background
PTFE pipes are increasingly used in self-cleaning pipelines, water supply pipes, water discharge pipes, gas pipes and the like. The polytetrafluoroethylene dispersion resin has the characteristics of extremely narrow phase change range and loose elasticity, so that the polytetrafluoroethylene dispersion resin is difficult to extrude or injection mold like common thermoplastic plastics. Extrusion of a paste mixture prepared by adding an appropriate organic solvent to a fine powder (PTFE dispersion resin) prepared by emulsion polymerization is a common processing method for PTFE dispersion resins.
The utility model with the publication number of CN204622528U discloses a polytetrafluoroethylene plastic rib pipe extruder. The utility model discloses an in through mouth type piece and plug with extruded material formation hollow pipe fitting.
The above prior art solution has the following drawbacks: the Teflon hose is easy to deform under stress due to higher temperature during the just extrusion molding, and can be completely shaped after being cooled. And the product is easy to deform and defective after being subjected to external large acting force before cooling.

By adopting the technical scheme, the guide pipeline is transited by the guide block with the arc-shaped upper surface, so that the pipeline is guided to the cooling device through the guide block without damage, and is cooled by the cooling device. Through the guiding device transition, the hose is prevented from being damaged and deformed when being transferred before cooling. The cooled hose still has the deformation capability, but can restore to the original shape after deformation.
The invention is further configured to: the upper surface of the guide block is provided with a guide groove extending from the side close to the discharge port to the side of the cooling device.
Through adopting above-mentioned technical scheme, make the pipeline carry in the guiding groove through the guiding groove for the pipeline is difficult for breaking away from the guide block at the in-process of carrying.
The invention is further configured to: the cross section of the guide groove is semicircular.
Through adopting above-mentioned technical scheme, semicircular guiding groove is because the bottom of cross-section is the arc, consequently is the cambered surface cooperation when cooperating with the hose, presses the laminating arcwall face when guiding the tank bottom under the action of gravity and has bigger area of contact than laminating the plane, therefore the type variable is also littleer.
The invention is further configured to: the guide block sets up on the adjustable shelf, the adjustable shelf includes the slide rail that sets up along the horizontal direction, the side of slide rail is equipped with the track hole along slide rail length direction, adjusting bolt pass behind the track hole with guide block threaded connection.
Through adopting above-mentioned technical scheme, the guide block moves and comes locking fixation through adjusting bolt along the direction in track groove for the horizontal position of guide block can adjust. The position of the discharge port just corresponds to the outer ring surface of the guide block through the adjustment of the horizontal position of the guide block, so that the hose can directly extend upwards to the guide groove after coming out of the discharge port, and the hose is attached to the inner wall of the guide groove and conveyed outwards.

By adopting the technical scheme, the direction of the arc surface of the horizontal section is parallel to the axis of the arc surface of the guide block, so that the bending direction of the hose after passing through the guide block is adaptive to the bending direction of the arc surface of the horizontal section. Therefore, when the hose enters the cooling track through the guide block, the hose cannot be deformed to be incapable of restoring due to the fact that the direction-changing angle is too large.
The invention is further configured to: the port of the cooling track at the horizontal section is positioned at one side of the horizontal section, which is back to the guide block, and the port faces upwards.
Through adopting above-mentioned technical scheme, the hose can contact the upper surface of horizontal segment earlier after the guide piece, gets into the cooling track after a distance along the horizontal segment behind the upper surface in, avoids the hose to turn the angle too big and lead to the hose impaired when getting into the cooling track.
The invention is further configured to: the port of the cooling rail at the vertical section is positioned on the side surface of the lower end of the vertical section, and a space is reserved between the cooling rail and the lower end surface of the vertical section.
Through adopting above-mentioned technical scheme, set up the position that the cooling track extends to vertical section lower extreme for the hose is as long as possible in the distance of cooling track interior process, increases its cooling effect.
The invention is further configured to: the outside of vertical section is equipped with the installing support, and the installing support includes a plurality of vertical bracing pieces and the connecting rod of joint support upper end and cooling tube, and the hookup location of connecting rod and cooling tube is higher than the orbital lower port position of cooling.
Through adopting above-mentioned technical scheme, set up the installing support and install fixed cooling tube, make the lower terminal surface of cooling tube leave certain distance between can leaving from ground through the bracing piece, the hose that comes out from the cooling track like this can coil subaerial to can directly take out after cutting the hose.
In conclusion, the beneficial technical effects of the invention are as follows:
1. the transition is realized through the guide device, so that the hose is prevented from being damaged and deformed when being transferred before being cooled;
2. the hose passes through the cooling track by coiling the cooling track on the cooling pipe, and cooling water is introduced into the cooling pipe, and heat of the hose is absorbed by the cooling water in the passing process, so that the hose is rapidly cooled.
