Description

High frequency is with position to thorn machine
Technical field
The present invention relates to needing machine, and in particular to a kind of high frequency is with position to thorn machine.
Background technology
Needle point method is one of main processing technology of non-woven cloth, and needing machine species is various, is wherein to thorn machine with position It is a kind of.
Frame, net feeding mechanism, lower stripping web plate, upper stripping web plate, acupuncture mechanism and draw-off mechanism are generally included to thorn machine with position; Upper stripping web plate is in above lower stripping web plate;Acupuncture mechanism includes acupuncture drive device, upper needing machine structure and lower needing machine structure, upper pin Thorn mechanism is in above stripping web plate, and lower needing machine structure is in below lower stripping web plate;Net feeding mechanism is led in front of acupuncture mechanism Drawing mechanism is located at acupuncture mechanism rear.It is lower stripping web plate and upper stripping web plate between gap be available for fibre web to pass through, it is lower stripping web plate with it is upper The gap region corresponding with acupuncture mechanism shelled between web plate constitutes acupuncture region.Net feeding mechanism by fibre web deliver to it is lower stripping web plate with Between upper stripping web plate, repeated puncture is carried out to fibre web by acupuncture mechanism(Upper needing machine structure and lower needing machine structure can be used under upper thorn Move back, move back alternate mode in lower thorn and carry out acupuncture;Can also upper needing machine structure to the fibre web first half carry out acupuncture, lower needing machine structure Fibre web lower half carries out acupuncture), fluffy fibre web is consolidated, the fibre web after acupuncture is by draw-off mechanism by it from acupuncture region Output.
Acupuncture mechanism is key components of the same position to thorn machine.In general, acupuncture in the acupuncture mechanism unit interval Number of times is more(I.e. punch frequency is higher), needling density(Acupuncture number in unit area)Higher, then the quality for obtaining fibre web is got over Good, production efficiency is higher.Therefore, the height of punch frequency is to influence one of key factor of product quality.
Existing upper needing machine structure includes upper transmission shaft component, upper lancet unit and multiple upper elevating drive mechanisms;Upload Moving axis component includes central shaft and fixed multiple eccentric wheels on center shaft, and central shaft may be rotatably mounted in frame(Generally, Central shaft two ends are connected by bearing with frame respectively)And it is connected with acupuncture drive device, eccentric wheel is passed with upper lifting Motivation structure quantity is identical and corresponds;Upper elevating drive mechanism is included on upper rocker arm, upper push-rod and upper guide sleeve, upper guide sleeve Lower to move towards and be fixedly mounted in frame, upper rocker arm upper end is socketed on transmission shaft component on corresponding eccentric wheel(It is generally logical Bearing is crossed to be socketed on eccentric wheel), upper rocker arm lower end is hinged with upper push-rod upper end, and upper push-rod lower end is connected with upper lancet unit, Upper push-rod is in guide sleeve.Upper lancet unit generally includes needle beam, needle plate and multiple prickers, and needle plate is fixedly mounted on needle beam Above and below needle beam, pricker is on needle plate lower surface(Pricker is uniform generally on needle plate lower surface), wherein needle beam It is connected with above-mentioned upper push-rod.The through hole for being available for the pricker of upper needing machine structure to pass through is equipped with upper stripping web plate.Acupuncture drive device When driving central shaft rotation, the multiple eccentric wheels rotation being fixed on above central shaft is driven, eccentric wheel passes through upper rocker arm, upper push-rod Lancet unit is done reciprocating linear motion in drive, and repeated puncture is carried out to fibre web.
Existing lower needing machine structure includes lower drive shaft component, lower lancet unit and multiple lower elevating drive mechanisms;Under pass Moving axis component includes central shaft and fixed multiple eccentric wheels on center shaft, and central shaft may be rotatably mounted in frame(Generally, Central shaft two ends are connected by bearing with frame respectively)And it is connected with acupuncture drive device, eccentric wheel is passed with lower lifting Motivation structure quantity is identical and corresponds;Lower elevating drive mechanism is included on lower shake-changing arm, lower push-rod and lower guide sleeve, lower guide sleeve Lower to move towards and be fixedly mounted in frame, lower shake-changing arm lower end is socketed on lower drive shaft component on corresponding eccentric wheel(It is generally logical Bearing is crossed to be socketed on eccentric wheel), lower shake-changing arm upper end is hinged with lower push-rod lower end, and lower push-rod upper end is connected with lower lancet unit, Lower push-rod is in lower guide sleeve.Lower lancet unit generally includes needle beam, needle plate and multiple prickers, and needle plate is fixedly mounted on needle beam Above and above needle beam, pricker is on needle plate upper surface(Pricker is uniform generally on needle plate upper surface), wherein needle beam It is connected with above-mentioned lower push-rod.The through hole for being available for the pricker of lower needing machine structure to pass through is equipped with lower stripping web plate.Acupuncture drive device When driving central shaft rotation, the multiple eccentric wheels rotation being fixed thereon is driven, eccentric wheel is driven by lower shake-changing arm, lower push-rod Lower lancet unit is done reciprocating linear motion, and repeated puncture is carried out to fibre web.
However, because above-mentioned upper transmission shaft component, lower drive shaft component are to install some eccentric wheels on center shaft to constitute , eccentric size of wheel is larger, and its gyrating mass is heavier, and work reciprocal inertia force is larger, and the vibration amount of evoking is quite big, therefore acupuncture The punch frequency of mechanism is greatly restricted(The highest punch frequency of most of acupuncture mechanisms can only achieve 1000rnp/ min), the raising of the quality and production efficiency of non-woven cloth is constrained, and the noise produced during work is also larger.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of high frequency with position to thorn machine, and this high frequency is with position to thorn machine Acupuncture mechanism has higher punch frequency, and the vibration amount of evoking is smaller, is conducive to improving production efficiency and product quality.Using Technical scheme it is as follows:
