Description
Technical field
The present invention relates to the marking fields of cable sheath, and in particular to a kind of double-colored extrusion molding for cable sheath
Machine.
Background technique
In the production process of cable, because needing to increase the mark of two kinds of colors on the oversheath of many product requirement cables
Line is known, so needing to connect 2 vitta extruding machines on the head of the main extruding machine of cable production, it is contemplated that installation space
Problem, angle of 2 vitta extruding machines on the head of main extruding machine is 90 °, i.e., the elongated central of 2 vitta extruder heads
The angle of line is 90 °.Currently, 2 vitta extruding machines are on the head of main extruding machine when the head of main extruding machine is horizontally disposed
Angle be 90 ° use structure there are two main ways:
(1) 1 vitta extruding machine is right above the head of main extruding machine and vertical with the head of main extruding machine, another 1 color
The head of extruding machine and main extruding machine keeps horizontal.But the vitta masterbatch of vertically disposed vitta extruding machine will receive it is vertical
The influence of straight downward self weight acceleration, the flow velocity that will lead to vitta masterbatch are greater than the vitta mother of horizontally disposed vitta extruding machine
Stream speed.The inconsistent machining accuracy and quality that can reduce marking line of the flow velocity of the vitta masterbatch of 2 vitta extruding machines.
(2) shown in Figure 1,2 vitta extruding machines are symmetrically disposed on 1 oblique upper of head of main extruding machine, each vitta
The head 7 of extruding machine is downwards and vertical with the head of main extruding machine 1, the head 7 of each vitta extruding machine by 1 bend pipe 8 and
The head 1 of main extruding machine is fixed.Bend pipe 8 includes integrally formed straight tube 8a and inclined tube 8b, straight tube 8a and inclined tube 8b in 135 °
Angle, straight tube 8a is parallel with the head 7 of vitta extruding machine (i.e. downwards and vertical with the head of main extruding machine 1), and straight tube 8a's is upper
End is connect with the head 7 of vitta extruding machine, and the lower end of inclined tube 8b is connect with the head 1 of main extruding machine.
Defect existing for method (2) are as follows:
After the head 1 of bend pipe 8 and main extruding machine is fixed, due to being integrally formed, the straight tube 8a and inclined tube 8b of bend pipe 8
Position can fix.When bend pipe 8 is because of installation error or processing dimension the problem of, cause the straight tube 8a of bend pipe 8 without and vitta
When the head 7 of extruding machine parallel (i.e. vertically downward), it is the position that can not adjust straight tube 8a, the side of external force can only be passed through at this time
It is fixed with the head 7 of vitta extruding machine after formula adjusts the position of straight tube 8a by force；This can not only increase installation difficulty, but also curved
The easy sealing of pipe 8 and 7 junction of vitta extruder head is bad to cause material leakage, and then changes the flow velocity of vitta masterbatch, therewith
Reduce the machining accuracy and quality of marking line.
At the same time, temperature reduces (temperature drop when flowing to the head 1 of main extruding machine through bend pipe 8 in order to avoid vitta masterbatch
The low flow velocity that can change vitta masterbatch), it needs to increase the heater for heating up to vitta masterbatch outside bend pipe 8.But
It is very difficult for being fixed on heater bend pipe 8 and will not impact to the installation site of bend pipe 8, and can be reduced
Heating effect thereby reduces the machining accuracy and quality of marking line.
Summary of the invention
