Abstract
The utility model discloses a non-contact material strip stable-blowing air knife, comprising an air knife vertical column, an air knife narrow gap and a non-contact material strip stabilizing device. An air collecting port, an air commuting zone and an air releasing vent are arranged on the non-contact material strip stabilizing device. The utility model makes use of the weak air blown from the air knife narrow gap, and the weak air is collected to form a negative pressure zone. Under the effect of atmosphere pressure, a great deal of air of the collecting port is absorbed to form a big air flow which enters the commuting zone; then an air flow layer is formed and the air flow flows along the surface of the material strip and the swing amplitude of the strip is limited into a small range so as to effectively stabilize the material strip; and the qualified rate of the material strips with big size and low thickness can be greatly enhanced during plating process. Moreover, a mechanical guide mechanism can be additionally arranged on the non-contact material strip stabilizing device of the utility model so as to avoid the possibility that a single mechanical guiding results in cracks caused by impact. The utility model can reduce energy costs and has the advantage that material strips cannot be scratched, cracked, coiled or broken off while passing through the air knife.
Description
Technical field
The utility model belongs to driving band type and electroplates production field, the contactless stable air blade device that dries up of particularly a kind of material bar.
Technical background
At present, the traditional widely used air blade device of driving band type electroplating assembly line as shown in Figure 1.These air blade device great majority only have two cylinders (air knife column) 4 that have slit, compressed air flows out the formation air knife at a high speed from the air outlet slit, through between the two air knife columns 4 time, utilize high velocity air to dry up residual chemical medicinal liquid on the material bar with convenient driving-belt 2 clamping material bars 3.Bar is swung significantly but traditional air blade device can cause material, and is especially all the more so to the material bar of large scale, minimal thickness, as shown in Figure 2.This is the asymmetric air knife that forms 5 of air-flow that blows out at a high speed owing to traditional air blade device, its flow field is also unstable, and the influence of the factors such as disturbance when being subjected to driving- belt 2 and 3 motions of material bar, the material bar produces swing, swing can cause the flow field to be worsened more again, form material bar swing 6 by a larger margin, so vicious circle causes the material bar electroplating when producing distortion or dropping.For the material bar of large scale, minimal thickness, its amplitude of fluctuation can be bigger, may cause finally expecting that bar can't pass through the technology cell body smoothly.Though the parcel plating production line has adopted such as increasing mechanical guide, slowing down measures such as material bar transfer rate, attenuating compressed air pressure, but can't tackle the problem at its root, the distortion of material bar when electroplate producing, hit and split or drop still very seriously, productivity ratio, qualification rate are very low.Owing to directly utilize compressed air to dry up, compressed air consumption is also very big simultaneously.Therefore seek the enough easy air blade devices of a kind of energy and prevent to expect that bar electroplating the distortion when producing or dropping, to the material bar of large scale, minimal thickness, electroplates the production qualification rate thereby improve especially, become a current technical problem that needs to be resolved hurrily.
Summary of the invention
The purpose of this utility model is to improve the defective that traditional air knife causes that the material bar is swung significantly, sets up the novel air blade device that dries up with stable high-speed air flow field.Prevent to expect that bar electroplating the distortion when producing or dropping, improves the plating production qualification rate of the material bar of large scale, minimal thickness significantly.Can stablize the material bar effectively, non-contactly dries up by each technology cell body and with it.
The purpose of this utility model is achieved in that described contactless material bar is stable and dries up air knife and be made up of air knife column 4, air knife slit 1, contactless material bar stabilising arrangement 7.Its design feature is: the air knife slit 1 at air knife column 4 blows out an end equipped with non-contact material bar stabilising arrangement 7, and contactless material bar stabilising arrangement 7 is provided with air scoops 8, air commutating zone 9 and air liberation port 10.Collect the small weak air knife 5 that compressed air blows out from air outlet slit 1 by contactless material bar stabilising arrangement 7, at this moment can form negative pressuren zone 11 at collection mouth 8 places near air knife, near air scoops 8 under the effect of atmosphere air is sucked in a large number, enters commutating zone 9 thereby produce mass air flow.Narrower commutating zone 9 can form a high speed advection airflow layer 13 in the cross section, near the material bar 3 that at this moment is in commutating zone 9 amplitude of oscillation of high speed advection air-flow when its surface is flow through just is limited in its dynamic equilibrium point very among a small circle in.The high velocity air of simultaneously big flow can be taken away residual chemical medicinal liquid and moisture content on the material bar 3 effectively.At last, air-flow chemical medicinal liquid and moisture content discharge by air liberation port 10.It is stable and to dry up the function of material bar all contactless, can not cause any type of destruction to the material bar.
Described contactless material bar is stable to dry up air knife, can set up mechanical guide mechanism 12 between contactless material bar stabilising arrangement 7 and air knife column.By establishing mechanical guide mechanism 12 to increase the guiding distance and can avoid single mechanical guide to cause the possibility of bump cracking.
The beneficial effects of the utility model are: can form a high speed advection airflow layer 13 by narrower commutating zone 9 in the cross section, high speed advection air-flow flows through along material bar 3 surfaces, the material bar 3 the amplitude of oscillation can be limited in one very among a small circle in, can effectively stablize material bar 3, prevent to expect that bar 3 electroplating the distortion when producing or dropping, the material bar that increases substantially large scale, minimal thickness is in the qualification rate of electroplating when producing.Simultaneously,, only need a spot of compressed air just can produce the high velocity air of big flow, can take away residual chemical medicinal liquid and moisture content on the material bar 3 effectively, reach the purpose that efficiently dries up the material bar because it has significant air enlarge-effect.Also reduced compressed air consumption, cost capable of reducing energy consumption.Owing to adopt contactless guiding, thereby scratch appears when having avoided the material bar through air knife, hit and split, the possibility of having stopped the material crimped or having come off.Described contactless material bar is stable to be dried up air knife and can unite use with mechanical guide mechanism 12, uniting when using with mechanical guide mechanism 12, can increase the guiding distance and can avoid single mechanical guide to cause the possibility of bump cracking.
