Description
Technical field
The utility model relates to a kind of skeleton pipe production equipment, specifically a kind of tube of large aperture framework polyethylene winding
Structure-wall pipe material production equipment runner exit.
Background technique
Polyethylene winding structure pipe is that the material strip for squeezing out flow passage system is wrapped on skeleton pipe in production, thus shape
At skeleton pipe polyethylene winding structure wall pipe, the fringe spacing of tubing is limited by material strip width, original polyethylene winding arrangement
The skeleton pipe that the flow passage system structure of wall tube material can reach cladding is up to DN80mm, and fringe spacing is up to 130mm, Zhi Nengsheng
Produce DN1200mm polyethylene winding structure wall pipe below.When skeleton pipe diameter is greater than DN80mm, existing modeling pipe manufacture is set
It is impossible to meet require for the high density polyethylene (HDPE) material strip width of the flat die flow channel structure basis of standby middle flow passage system.At this time
Polyethylene winding structure wall pipe bore, which is greater than DN1200mm, must just take increasing using original production equipment flow passage system structure
Add the number of plies of winding solid wall pipe to reach the requirement of product design ring stiffness, the polyethylene winding structure wall pipe of production is not
Foot place is that raw materials consumption is more, and product is heavy and at high cost.
Utility model content
The purpose of this utility model is just to provide a kind of production device of wall tube of large aperture framework-tube polyethylene winding structure
Runner exit can not produce the sufficiently large polyethylene material strip of width to solve the prior art so as to cause production heavy caliber polyethylene
Raw materials consumption is more when winding structure wall pipe, product weight and problem at high cost.
The utility model is realized in this way: a kind of production device of wall tube of large aperture framework-tube polyethylene winding structure stream
Road outlet, including wide flow channel and the flat die being connected with the wide flow channel, in the wide flow channel
Portion is provided with runner mouth, and the arrival end of the runner mouth is circular port, and outlet end is flat port, and the both ends of the flat port are semicircle
Shape, two semicircles are connected by two straight flanges being parallel to each other；Round and smooth connection between the circular port and flat port.
The die orifice of the flat die, which passes through, to be gradually increased, the outlet at the osculum end of die orifice and the runner mouth
End is connected and length direction is consistent.
The maximum length of the outlet end is 180~280mm.
The utility model meets the needs of production technology by changing the structure of wide flow channel and flat die, will be wide
The runner mouth size of flow channel becomes 180~280mm, the runner mouth length and flat die of the wide flow channel of simple increase
Die length be unable to satisfy process requirements, so the outlet end of wide flow channel is also changed to flat port, and make flat die
Die orifice be the structure become larger.
The utility model can make material strip width reach 170mm~230mm, make the striped of polyethylene winding structure wall pipe
Spacing reaches 170mm or more, and in the case where reaching like products design ring stiffness, product weight reduces by 15% or more, makes
Raw materials consumption is reduced, and product cost is low.

Specific embodiment
The utility model includes wide flow channel 1 and the flat die 5 that is connected with wide flow channel 1.
As shown in Figure 1, Figure 2 and Fig. 3 shown in, wide flow channel 1 be it is discoid, the end of flow passage system is mounted on, in wide machine
At least two bolts hole are provided in the disk of head runner 1, and are bolted.Runner is provided at the middle part of wide flow channel 1
Mouth 2, the arrival end 3 of runner mouth 2 are circular port, and outlet end 4 is flat port, and the both ends of flat port are semicircle, two semicircles
It is connected by two straight flanges being parallel to each other, round and smooth connection between circular port and flat port.The arrival end 3 of 1 mouthful of wide flow channel with
The end outlet of flow passage system is connected, and the outlet end 4 of 1 mouthful of wide flow channel is connected with the die orifice 6 of flat die 5.Wherein, out
The maximum length at mouth end 4 is 180~280mm.
As shown in Figure 3 and 4, flat die 5 is a cuboid, and the mould of prolate is provided on the length direction of cuboid
Mouth 6, the die orifice 6 of flat die 5, which passes through, to be gradually increased, and the osculum end of die orifice 6 is connected with the outlet end 4 of runner mouth 2
Logical and length direction is consistent.
The utility model meets the needs of production technology by changing the structure of wide flow channel 1 and flat die 5, will
2 size of runner mouth of wide flow channel 1 becomes 180~280mm, 2 length of runner mouth of the simple wide flow channel 1 of increase and
6 length of die orifice of flat die 5 is unable to satisfy process requirements, so the outlet end 4 of wide flow channel 1 is also changed to flat port, and
And the structure for becoming larger the die orifice 6 of flat die 5.The plastics squeezed out in this way by extruding machine are by flow passage system and through wide
Flow channel 1 is discharged, and the plastics of molten form uniform flat-shaped after being discharged from outlet end 4, subsequently into flat die 5,
It is finally discharged from the osculum end of flat die 5, forms sufficiently wide material strip, and be uniformly wrapped in material strip in subsequent process
On skeleton pipe, to complete the processing of skeleton pipe.
The utility model can make the fringe spacing of polyethylene winding structure wall pipe reach 170mm or more, and reach
In the case where designing ring stiffness to like products, product weight reduces by 15% or more, reduces raw materials consumption, product cost is low.
