Problems solved by technology

[0003] At present, the production method of fire extinguisher siphon is mainly through cutting (that is: cutting a long plastic pipe into multi-section fire extinguisher inner tube embryos), breaking and extruding the thread of the end (or joint). In the compression forming step, the existing methods mostly adopt thread forming machines, for example: the applicant disclosed the external thread forming process and equipment of the plastic pipe joint in the patent document CN101195272A on January 8, 2008. Invention patents, but this type of patent has a common problem, that is, after extrusion molding of each plastic pipe joint, it needs to be manually taken out, and then artificially accurate feeding (that is, the plastic pipe needs to be accurately inserted into the molding equipment In the extrusion cavity), not only the process is cumbersome, but also the production efficiency is very low

Embodiment 1

[0028] like Figure 1 to Figure 7 As shown, the present invention discloses an external thread hot extrusion molding machine for a fire extinguisher siphon, which includes a frame 1, and in a specific embodiment of the present invention, includes a screw thread installed on the frame 1 and used to extrude a plastic pipe joint Forming component 2, preheating component 3 for heating plastic pipe joints, and conveying component 4 for combing plastic tubes and feeding them into preheating component 3 for heating and thread forming component 2 for thread forming .

[0029] In a specific embodiment of the present invention, the conveying assembly 4 can convey two plastic pipes into the thread forming assembly 2 at a time.

[0030] In a specific embodiment of the present invention, the conveying assembly 4 includes at least two groups of transmission sprockets 40 rotatably connected to the frame 1, transmission chains 41 laid on and engaged with each group of transmission sprockets ...

Embodiment 2

[0054] Embodiment 2, the difference with embodiment 1 is that

[0055] like Figure 8 As shown, in the specific embodiment of the present invention, it also includes a limiting device 5 for limiting the movement of the transmission chain 41 at intervals; ) the limit block 51 inside.

[0056] By adopting the above technical solution: when the plastic pipe is being shaped (that is: one end of the plastic pipe is in the thread forming assembly), in order to prevent the transmission chain from moving (for example: due to equipment failure), the transmission chain can be snapped into the transmission chain through the limit block In the chain ring, it can achieve the effect of limiting the transmission chain and ensure the efficiency of production.

Embodiment 3

[0057] Embodiment 3, the difference with the foregoing embodiment is that

[0058] like Figure 9 , in a specific embodiment of the present invention, a layer of heat transfer plate 6 for transferring the internal heat of the hot air pipe 322 to the plastic pipe joint is provided in the bottom of the preheating tank 300 .

[0059] In a specific embodiment of the present invention, the thickness of the heat transfer plate 6 can gradually become thicker from the conveying direction of the conveying assembly.

[0060] In a specific embodiment of the present invention, the heat transfer plate 6 may be provided with a hot gas discharge channel 60 that passes through the heat transfer plate 6 from the direction of the conveying assembly and communicates with the hot air pipe 322 .

[0061] By adopting the above technical solution: the heat transfer plate can not only ensure that the joints of the plastic pipes are softened due to heat, but also avoid blowing the plastic pipes due t...

Abstract

The invention relates to an external screw thread hot extrusion molding machine for a fire extinguisher siphon pipe. The external screw thread hot extrusion molding machine comprises a rack and is characterized by comprising a screw thread molding component installed on the rack and used for extruding a plastic pipe connection mouth, a preheating component used for heating the plastic pipe connection mouth and a conveying component used for combing plastic pipes and feeding the plastic pipes to the preheating component for heating and to the screw thread molding component for screw thread molding in groups correspondingly in sequence. The external screw thread hot extrusion molding machine for the fire extinguisher siphon pipe has the beneficial effects that the production efficiency is high, and other processing steps are all automatically completed by the external screw thread hot extrusion molding machine except material feeding and packing.

Description

technical field [0001] The invention relates to the technical field of plastic pipe interface thread forming equipment, in particular to an external thread hot extrusion forming machine for a siphon pipe of a fire extinguisher. Background technique [0002] Plastic pipe refers to the general use of synthetic resin, that is, polyester, as raw material, adding stabilizers, lubricants, plasticizers, etc., and extruding in a pipe making machine in a "plastic" method. It is mainly used for water supply system piping, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation in housing construction; plastic pipes are widely used, for example: they can be used in fire extinguishers The interior acts as a medium for transporting fire extinguishing substances (for example: dry powder), which can also be called: fire extinguisher siphon inside the fire extinguisher; [0003] At present, the production me...
