Description
Technical field
The present invention relates to extruder technology fields, more particularly to a kind of Punching Plunger Extruder.
Background technique
Extruder is a kind of for plastic raw materials to be melted to the mechanical equipment of extrusion molding again, common are Screw Extrusion
Machine, but screw extruder is for after the polymer meltings such as PTFE, PE-X, UHMW PE there is very high viscoplasticity to be not appropriate for making
With such thermoplastic is not also good enough using screw-type extruder processing effect, it usually needs is squeezed out using punching type plunger
Machine is processed.Punching Plunger Extruder drives plunger to realize and moves back and forth using driving mechanism, and the course of work is by material
It is pressed into machine barrel, melts material constantly in machine barrel, and keep material downward under the promotion of the pressure of plunger
Downstream is finally through mouth mold extrusion molding.Current Punching Plunger Extruder uses crankshaft jointed crank connecting rod mechanism as biography
Motivation structure moves back and forth plunger rod, but this transmission mechanism is hinged using multiple tracks, and not only occupied space is big but also transmission is unstable
When determining, and curvilinear motion being changed into linear motion using connecting rod, the force request of power size and connecting rod to input is all non-
Chang Gao.There is also a kind of extruders using worm screw in the prior art（Plunger type rubber disclosed in Publication No. CN202147387U
Rubber extruding machine）, worm-drive is used, it is small to move required space, and it is more preferable more stable and can will be electric to be driven effect
The power of machine is converted into straight line, this Worm type transmission can only one direction transmission, to realize reciprocatings motion, it is necessary to which use is just
Invert motor.But use clockwise and anticlockwise motor but troublesome in poeration, the problems such as great work intensity and dangerous operation.Contactor connection
It is safe and reliable to lock positive and reverse rotation control circuit；But it is inconvenient, because motor is from when just going to reversion, it is necessary to first press and stop
Only after button, reversion starting button could be pressed, otherwise since the interlocking effect of contactor can not achieve reversion.Button interlocking is positive and negative
It is easy to operate to turn control circuit, but is easy to produce power supply two-phase short-circuit fault, such as melting welding occurs when rotating forward main noddle on contactor
Or sundries, when the failures such as blocking, even if contactor coil power loss, main contact also do not open by disjunction, starts if at this moment directly pressing reversion
Button, inverts contactor energized action, and contact closure necessarily causes power supply two-phase short-circuit fault.Therefore, in the prior art
There are problem, a kind of it is urgent to provide transmission spaces small, transmission effect stability is squeezed without the engagement type transmission of motor positive and inverse
Machine is particularly important out.
Summary of the invention
There is provided that transmission space is small, transmission effect is steady it is an object of the invention to avoid shortcoming in the prior art
Punching Plunger Extruder that is fixed, can be achieved with straight reciprocating motion without motor positive and inverse.
The purpose of the present invention is achieved through the following technical solutions：

Plug moves back and forth transmission material in main processing part.Wherein, motivation structure includes partial gear, double sided rack component and subtracts
Fast device, partial gear are the incomplete gear of the number of teeth, and partial gear is connected with transmission shaft, and motor passes through retarder and transmission
Axis is drivingly connected, and double sided rack component is equipped with two rack gears for being parallel to each other and being oppositely arranged, and the width of rack gear is equal to or greatly
In the teeth portion width of partial gear, and the two sides of rack gear are equipped with limit raised line, and the tooth of partial gear can be with two teeth
Engaged transmission, plunger are parallel with rack gear and affixed with double sided rack component respectively for item；Successively pacify between transmission shaft and retarder
Equipped with plum blossom yielding coupling, magnetic powder cluth and plum blossom yielding coupling.
Preferably, the corresponding central angle alpha of partial gear toothed portion must meet the following conditions：
, wherein
rf：Partial gear toothed portion root radius；
ra：Partial gear toothed portion radius of addendum.
Preferably, the part that partial gear is equipped with the number of teeth accounts for the half of the circumferential edges of gear.
Preferably, be additionally provided with guiding device, guiding device includes supporting table and guide rail, guide rail be installed on supporting table and with
Plunger is parallel, and the sliding block of double sided rack component and guide rail is affixed and slides along guide rail direction.
Preferably, double sided rack component is structure as a whole with plunger.
Beneficial effects of the present invention：
Double sided rack component of the present invention using partial gear and with two opposite rack gears is driven, and works as partial gear
Double sided rack component can be driven to push plunger advancement when engaging with the rack gear of wherein side, when the tooth of partial gear and the other side
It can make double sided rack component that plunger be driven to retreat when item engaged transmission.Crank and rocker mechanism compared to transmission is driven, and the present invention makes
More stable with rack pinion, movement is more smooth, so as to make material more evenly, helps to improve quality of item, Er Qieben
The transmission efficiency of invention is more preferable, and transmission efficiency can be improved 20% or more, in addition, the engaged transmission of rack-and-pinion is than crank rocker
Space and energy conservation are hingedly more saved, energy-saving efficiency is than traditional energy saving transmission about 30%, further, transmission parts of the present invention
It is more wear-resisting, it is not easy to damage, the service life is long and failure rate is low.The teeth portion that the width of rack gear is equal to or more than partial gear is wide
Degree, and the two sides of rack gear are equipped with limit raised line, and such setting can be such that partial gear is limited between two limit raised lines,
Prevent the relative displacement in moving process of partial gear and double sided rack component from deviating from and causing failure.
Plum blossom yielding coupling, magnetic powder cluth and plum blossom bullet are sequentially installed between transmission shaft and retarder of the invention
Property shaft coupling.Adding clutch can be improved safety, reduce energy consumption, not assist when there is fortuitous event that processing or each process is needed to cooperate
Tighten it is close close clutch power supply immediately, motor and host motion separated when needing to shut down, and do not have to close motor, reduce
The start-stop time of motor reduces energy loss, increases motor service life.Meanwhile it being adopted between magnetic powder cluth and gear shaft
It is connected with plum blossom yielding coupling.By the plum blossom elastic element being placed between two half a coupler dogs, to partial gear and
Buffer function is played in the impact that rack gear generates when engaging, and reduces equipment running stability, reduces noise.
