Abstract

The utility model discloses a plastic drawing rotary switching efficient combined separating knife, and relates to a knife for drawing in the field of plastic product production. The plastic drawing rotary switching efficient combined separating knife is formed by supports, a roller, knife rests and blades. The supports are movably installed at the two ends of the roller in a matched mode, the one ore more knife rests are arranged on the roller in a sleeved mode, and the one or more blades are fixed on the circumferences of the knife rests. The round knife rests are installed on the roller in a close fit and sleeved mode, the outer ends of the two sides of the round knife rests are provided with pressing nuts in a sleeved mode, and the round knife rests are locked through spare nuts. The plastic drawing rotary switching efficient combined separating knife is reasonable in design and convenient to install, any modification does not need to be carried out on an original plastic drawing unit analysis system, only the plastic drawing rotary switching efficient combined separating knife needs to be connected with a plastic drawing unit separating mechanism, the number of separating blade sets capable of being installed is increased, switching is convenient to achieve, and the practical effect is remarkable; according to the controllable rotary replacement blade sets, the stop time of an original plastic drawing unit with a single set of blades and a single knife rest is greatly shortened, the stop time number of the original plastic drawing unit with the single set of blades and the single knife rest is greatly decreased, the production efficiency is improved, and the production cost is reduced.

Description

Efficient combination sub-wire cutter is switched in plastic wire-drawing rotation

Technical field

The utility model relates to a kind of plastic products production field wire drawing silk cutter, relates in particular to a kind of plastic wire-drawing rotation and switches efficient combination sub-wire cutter.

Background technology

Moulding and compiling industry is the industry of being combined with textile industry between plastic processing, and along with the extensive use of establishment product in all trades and professions are produced moulded by China, China moulds the status of volume industry and improves gradually.But along with International Crude Oil continue soaring, and country to advocate energetically " science is sustainable " " low-carbon environment-friendly " industrial current, mould that the production efficiency of compiling industry production equipment improves, energy-saving and cost-reducing having become moulded the cardinal task of compiling industry.As mould compile industry production " tap "---plastic wire-drawing unit is particularly important.Plastic wire-drawing unit production technology is: after plastic raw materials and auxiliary material mixture, by extruder heating and melting, by extruder, it is melt extruded into film, film is through supercooling, cut apart slivering silk (base silk), produce flat filament through hot-stretch orientation, sizing again, finally these flat filaments are wound on bobbin, make spindle.Wherein, it is a vitals of plastic wire-drawing unit that flat filament divides silk device, and it is made up of assemblies such as a point screwknife post, blades.At present, point screwknife post that plastic wire-drawing unit uses can only be installed one group of blade, and blade there will be the situation of blade wearing and tearing in flat filament continuous flow procedure, can cause flat filament to cut apart bad, has a strong impact on follow-up flat filament hot-stretch, shapes, is wound in the operations such as ingot.At this moment just need operating personnel to shut down, change set of blades or use knife rest for subsequent use.Like this, in the process of plastic wire-drawing unit startup-shutdown allowing blade replacement, just cause production discontinuous, increased material loss, increased energy consumption, reduced Flat Yarn Production efficiency.

Summary of the invention

The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of plastic wire-drawing rotation to switch efficient combination sub-wire cutter.

Efficient combination sub-wire cutter is switched in plastic wire-drawing rotation of the present utility model, formed by support, cylinder, knife rest and blade, moving cooperation of two ends at cylinder is equipped with support, and on cylinder, suit has been arranged more than one knife rest, has fixed more than one blade on the circumference of knife rest.

As further improvement of the utility model, described some circular knife rest tight fit is set on cylinder, its outer end, both sides has been set with pressure cap, also use standby cap locking.

As further improvement of the utility model, the internal diameter of the described knife rest that is set in cylinder periphery and cylinder external diameter phase tight fit, the circumference of multiple blades and knife rest is the corner cut that tilts in the same way, same loop wire is fixedly planted in knife rest.

As further improvement of the utility model, described several knife rests that are set with on cylinder, are all same interval on the circumference of each knife rest, same to inclination angle, with the blade of number, be formed in the leggy set of blades of cylinder peripheral, axial.

As further improvement of the utility model, the ratchet that has been one stationary fit on the termination of cylinder outside described at one end support, the moving crown of ratchet and the tooth peak of ratchet coordinating is meshed.

Efficient combination sub-wire cutter is switched in plastic wire-drawing rotation of the present utility model; reasonable in design, easy for installation; original plastic wire-drawing group machine analytical system is without doing any change; this device and plastic-wire drawing machine group divided mechanism need only be linked; and installable sub-wire set of blades number increases, easy switching practical function is remarkable; change set of blades by controllable rotating; plastic wire-drawing unit downtime and the number of times of original single group blade knife rest are greatly delayed; improve production efficiency, reduced production cost, there is great Practical significance.

The specific embodiment

As shown in Figure 1, efficient combination sub-wire cutter is switched in plastic wire-drawing rotation of the present utility model, is made up of support 1, cylinder 2, knife rest 3 and blade 4.Moving cooperation of its two ends at cylinder 2 is equipped with support 1, and on cylinder 2, suit has been arranged one with upper tool post 3, and on the circumference of knife rest 3, has fixed more than one blade 4, as 6,8 or 10.

Described knife rest 3 is circular, and its tight fit is set on cylinder 2, its outer end, both sides has been set with pressure cap 5, and with locking for cap 6.

The internal diameter of the described knife rest 3 that is set in cylinder 2 peripheries and cylinder 2 external diameter phase tight fits, the multiple blades 4 on same knife rest 3 along the circumference of knife rest 3 be the corner cut that tilts in the same way, same loop wire is fixedly planted in knife rest 3, as shown in Figure 2.

And described knife rest 3 is several knife rests 3 of suit on cylinder 2, on the circumference of each knife rest 3, is all same interval, same to inclination angle, is formed in the leggy set of blades of cylinder 2 peripheral, axial with the blade 4 of number.

This device, outside support 1 one end on the termination of cylinder 2 integral stationary fit ratchet 7, the moving crown of ratchet 8 and the tooth peak of ratchet 7 coordinating is meshed, as shown in Figure 3.
