Frictional force, and the power of spring reset, core rotation is can be achieved with, dexterously solves very much the liquid plastic bag that presently, there are
Uniformity and cladding quality problems during covering.
Prioritization scheme 1, the further optimization to base case, along cored wire moving direction, the gap of taper interlayer gradually subtracts
It is small.When setting in a manner described, it can guarantee that the last plastics being coated on outside cored wire are more closely knit, covered effect is more preferable.
Prioritization scheme 2, the further optimization to base case, the taper interlayer periphery are provided with zone of heating, zone of heating
Heating-up temperature is 120-125 DEG C.Because electric heating coil is located at outside handpiece body, part heating effect between mouth mold and core block compared with
Difference, liquid plastic are difficult to flow, after setting above-mentioned zone of heating, can guarantee that in taper interlayer in the easily solidification of taper interlayer content
Liquid plastic flowing is smooth, so as to ensure the effect of cladding.
Prioritization scheme 3, the further optimization to any one of base case, prioritization scheme 1,2, outside second annular gap
Provided with annular cooling chamber, and the temperature in annular cooling chamber is 75-80 DEG C.In the passage of mouth mold, liquid plastic is coated
On cored wire, set annular cooling chamber that the liquid plastic outside cored wire tentatively can be shaped, ensure the electric wire from mouth mold output
It can finalize the design almost, ensure the quality of coating plastic.
Prioritization scheme 4, the further optimization to prioritization scheme 3, steam is passed through in the zone of heating, and zone of heating is minimum
Place is connected with annular cooling chamber, and mouth mold is pacified provided with being connected with annular cooling chamber and being used for water filling and the water pipe of draining on water pipe
Equipped with valve.During using said structure, condensed after the heat absorption of steam in zone of heating, condensed liquid substantially also at 75-80 DEG C,
After liquid is flow in annular cooling chamber, moreover it can be used to which liquid plastic is tentatively shaped, ingenious in design and economize on resources.

Condensed after steam heat absorption in layer, condensed liquid is substantially also at 75-80 DEG C, after liquid is flow in annular cooling chamber, moreover it is possible to
Tentatively shaped for liquid plastic, it is ingenious in design and economize on resources.
Specific workflow and principle：
Illustrated below by taking embodiment 1 as an example：The cored wire of plastics to be covered is penetrated from the through hole of core block side,
Passed from the through hole of mouth mold side, liquid plastic is constantly injected in the first annular interlayer into core block, liquid plastic is successively
Flow and be coated on outside the cored wire moved along first annular interlayer, taper interlayer and the second annular gap.Often moved during use
Dynamic cored wire 1min, stop mobile 0.5s, so that core rotates under cored wire drive, inverted afterwards under the reset response of spring.
In cored wire moving process, there is frictional force, in rubbing for cored wire between the rubber layer in the through hole of cored wire and driving rod
In the presence of wiping power, and because driving rod away from core one end is provided with the guide that is slidably connected with core block, so driving
Rod moves close to core side, because driving rod be threadedly coupled with core, and core and core block rotation connection, so driving rod
Core can be driven to rotate, now core will make the liquid plastic in taper interlayer flow, and can break completely
Close to the liquid plastic trapping phenomena of mandrel surface, liquid plastic is set to be constantly in uniform state, so as to ensure to be coated on core
The uniformity and quality of the plastics on line surface are preferable.Other rubber layer can be by the oxygen on its surface during being rubbed with cored wire
Change layer to remove, improve the electric conductivity of cored wire, this programme utilizes the frictional force between cored wire moving process and driving rod, and bullet
The power that spring resets, core rotation is can be achieved with, dexterously solved very much during the liquid plastic that presently, there are coats uniformly
Property and cladding quality problems.
