Problems solved by technology
[0002] The existing manufacturing steps of insulating tubes include (1) applying tape; (2) heating the mold; (3) wrapping the tape around the mold; (4) extruding while heating; (5) curing in an oven; Grinding and other steps, by wrapping the tape outside and fixing the tape on the insulation pipe to increase the hardness of the insulation pipe, and the existing mold itself is not heated, in fact, there will be defects such as creases and rough surfaces during extrusion molding, and the size It is difficult to control, and after the existing products are processed, due to the heat and extrusion of the tape, it will adhere to the outside of the mold, which is inconvenient to take out the material. Therefore, we propose a production process and device for insulating pressed tubes

Embodiment Construction
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0030] see Figure 1-6 , a production process of insulating pressed tubes in the illustration, including the following steps:
[0031] Step 1, apply adhesive tape, take out the raw material of adhesive tape;
[0032] Step 2, mold heating, will use the heating plate in the mold to heat the mold body, so as to heat the adhesive tape wrapped outside the mold to facilitate subsequent shaping;
[0033] Step 3, wrap the tape around the mold, wrap the tape to the o...

The invention discloses a production device for insulated pressure pipes, which comprises a mold, the mold is a hollow cylinder structure, and a driving device is installed and fixed in the mold, a plurality of heating cavities are opened in the mold, and the heating cavities A heating plate is fixed inside, and the present invention heats the mold body through the heating plate in the mold, so as to heat the adhesive tape wrapped outside the mold, so as to prevent creases, surface roughness and other defects, and facilitate subsequent extrusion molding. When removing the adhesive tape, the air bag is deflated and the contact plate is retracted into the jacking arc groove, thereby reducing the contact area between the mold and the adhesive tape, facilitating the removal of the adhesive tape, and improving the production efficiency of the adhesive tape.
Description
technical field [0001] The invention relates to the technical field of insulating tube manufacturing, in particular to a production process and device for insulating pressed tubes. Background technique [0002] The existing manufacturing steps of the insulating tube include (1) adhesive tape; (2) mold heating; (3) adhesive tape wrapped around the mold; (4) extrusion while heating; (5) oven curing; (6) processing and forming, the outer diameter Grinding and other steps, by wrapping the tape outside and fixing the tape on the insulation pipe to increase the hardness of the insulation pipe, and the existing mold itself is not heated, in fact, there will be defects such as creases and rough surfaces during extrusion molding, and the size It is difficult to control, and after the existing products are processed, the adhesive tape will adhere to the outside of the mold due to the heating and extrusion, which is not easy to take out the material. Therefore, we propose a production ...
