Abstract
Disclosed is a vertical heat shrinking pipe vacuum/ inner air combined pipe expander. A working cabinet is provided with a vertical heater box whose back cut is provided with a driving mechanism and under cut a pipe expanding mould fixed to an installing rack. A vacuum air duct, a cooling water pipe and an escape-pipe are coupled in, and a lower driving mechanism is arranged in the working cabinet. The working cabinet also can be provided with an auxiliary traction mechanism. The utility model has the advantages of simple application, wide expansion range, stable production quality and high qualified rate.
Description
Affiliated technical field
The utility model belongs to the device of plastic processing technical field, refers in particular to a kind of the plastic hot collapsible tube to be carried out continuous expanded device.
Background technology
At present commonly used the plastic hot collapsible tube is carried out continuous expanded device press pipe expander and horizontal glycerine pipe expander in having.In press pipe expander expander speed fast, but quality instability, the technological operation difficulty can only be expanded the following production tube of Φ 16mm, and the pipe of being expanded has radial and axial shrinkage factor, product percent of pass is low.This machine profile is simple, but heating cabinet needs sealing, makes relatively difficulty.Horizontal glycerine pipe expander is the maximum a kind of type of present domestic application, it is simple in structure, the expansion scope is wide, and product quality qualification rate height adopts the higher glycerine of heatproof to make heat transfer medium, have advantages such as heat conduction is fast, stable, power saving, machine generally can semiautomatic control, and equipment manufacturing cost is low, and its shortcoming is that waste of glycerine volatility and air pollution are serious, institute goes out product will be cleaned, and scalds easily when the workman operates.In addition as Chinese patent once disclosed a kind of " vacuum type plastic hot collapsible tube pipe expander " (ZL96200490.1, the day for announcing: 1997.06.11), it comprises that heater, cooling device, mother tube send into mechanism, production tube exhaustion mechanism, between heater and the production tube exhaustion mechanism vacuum chamber is set, the outlet side of vacuum chamber is connected with the production tube exhaustion mechanism, and the entrance side of vacuum chamber is connected with the outlet side of heater; Vacuum chamber by be connected the vacuum gap in vacuum chamber cover on the ring flange, the cover, vacuum breaker, the vacuum exhaust pipe that is arranged on the vacuum chamber cover constitutes; Cooling body is by the cooling jacket that is positioned at vacuum chamber, and the cooling water inlet pipe that is communicated with cooling jacket, cooling water outlet pipe and cooling water pipe constitute; Vacuum gap is positioned at the mother tube that enters vacuum chamber and the junction of production tube.It also belongs to a kind of horizontal pipe expander.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of vertical heat-shrink tube vacuum/interior gas associating pipe expander is provided, and it is easy and simple to handle, and the expansion scope is wide, constant product quality, qualification rate height.
For achieving the above object, the solution that the utility model adopts is: a kind of vertical heat-shrink tube vacuum/interior gas associating pipe expander, vertical heating cabinet is installed on one working cabined, this vertical heating cabinet transmission mechanism that is provided with suitable for reading, end opening is provided with the expander mould, the expander mould is fixed on the installing rack, inserts vacuum wireway, cooling water pipe and drainpipe, and underdrive mechanism is set in working cabined.
On working cabined, also auxiliary traction mechanism can be set.
Coil supporting uses such as auxiliary frame, special-purpose pad printer, finished product packing machine on the utility model and automatic feeding machine, automatic finished product coiling machine, combination of circuits control flow, vavuum pump, water passage circulation system, air compressor, water tower or water tank, the pipe, form vertical heat-shrink tube vacuum/interior gas associating pipe expanding set, can adopt the modularization design, integral layout is reasonable.The equipment automatization design is easy, expansion scope wide (from Φ 3mm～Φ 150mm).The comprehensive production craft step of unit is as follows: (1) twists in crosslinked pipe on the feed wheel disc of automatic feeding machine by dish auxiliary frame on the pipe, nos segmentation in the middle of the pipe, do not have and leak gas, the gas guide nozzle of the same core rotating shaft gas directing system on an end and the automatic feeding machine links to each other firmly; (2) corresponding expander mould is fixed on the installing rack, inserts vacuum wireway, cooling water pipe and drainpipe; (3) according to pipe size with to require speed different, the temperature of heating cabinet is set; (4) temperature to be heated is raised to the temperature of setting, feed automatic switch on the open circuit combination control flow, upward defeated frequency converter, down defeated frequency converter, batch switch etc. automatically, the initial stage is regulated with low speed, treats that expansion quickens after stable gradually, will coordinate up and down; (5) pipe that has heated comes out to introduce underdrive mechanism from the expander mould, moves to through auxiliary traction mechanism on the finished product wheel disc of automatic finished product coiling machine, can finish automatic feed and finished product and batch operation, opens cooling water and injects the expander mould; (6) open vavuum pump, cover expander mould finished product delivery outlet with hand or cloth, allow vacuum fully adsorb and heated pipe, treat that pipe expanded shaping, can unclamp hand, regulate the vacuum flow according to extensibility then, detect finished product thickness with micrometer, after qualified, improve transporting velocity gradually, be fixed to certain numerical value then and can stablize expansion; (7) in process of expansion, whether the external diameter of pipe evenly directly affects the quality of product, if pipe is even, then need not to regulate the vacuum flow, if it is inhomogeneous that the pipe external diameter is extruded, in process of expansion, then can cause quality fluctuation, need the operator suitably vacuum flow and interior pressure to be adjusted, reach the expansion requirement; (8) finished product of having expanded is taken off from automatic finished product coiling machine, residual moisture on the airing pipe just can printing package.It is easy and simple to handle, utilizes air heat conduction not exist environmental pollution and finished product to clean problem.
