Description

A kind of soldering joint powder spraying device
Technical field
The utility model relates to plastic powders soverlay technique equipment, specifically is with the powder spraying device of weld seam protection layer to be formed on a kind of weld seam that thermoplastic or heat curing-type powder is covered metal can body inwall with spraying and the method for Electrostatic Absorption.
Background technology
The packing metal can of being produced by metal sheet is a class of the article packaging container that generally uses at present, and the can body of this metal can adopts the alternating-current resistance seam welder to weld it after by the metal sheet bending to connect seam and moulding usually.Because the general former existing etch-proof protective layer in the metal sheet surface of system jar; the internal face of can body can reach etch-proof general requirement; itself does not then have etch-proof protective layer weld seam behind the can body welding fabrication; so weld seam often will become the weak spot that is subject to the packed article corrosion; weld seam is corroded; not only can make the packing container poor durability, and the material that corrosion generates can pollute packed article, cause the packed article qualitative change.And in the safeguard measure to the employing of can body weld seam, the coating plastic protective layer can be applicable to the corrosion property of various packed articles, beyond doubt comparatively desirable safeguard measure.The solution of this problem is to adopt electrostatic power spraying apparatus to treat to form a plastic protective layer through later process at whole can body inner-wall spraying plastic powders again, as adopting " technique for coating inside wall of metal pipe with plastic powder " of Chinese patent ZL92112180.6 number.But, owing to the very little anticorrosion problem of weld seam of area whole can body inwall is sprayed, be undoubtedly a kind of serious waste, can increase a system jar cost greatly, and its operating efficiency is not high, be not suitable for low cost, the use of high efficiency system jar industry.The general powder spray coating device of present widespread usage can not carry out locally sprayed to can body inwall weld seam, and has powder recovery system imperfection, and powder utilization rate again is low, and the powder wastage is big, and the dirt powder of operating environment is seriously polluted, easily causes equipment to stop up.
Summary of the invention
For the weld seam that solves existing metal can body does not have the anti-corrosion protection layer, tends to become the weak spot that is subject to the packed article corrosion; can not carry out locally sprayed to can body inwall weld seam with existing general powder spraying device; and utilization rate is low again, the powder wastage is big powder recovery system imperfection, powder; the dirt powder of operating environment is seriously polluted, easily cause problems such as equipment obstruction; the purpose of this utility model provides a kind of improved a kind of soldering joint powder spraying device, can solve prior art problems.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of soldering joint powder spraying device, it is characterized in that: comprise frame and rack-mounted main powder bucket, podwer gun, arm dusts, reclaim and filter the powder bucket, outer recover, vavuum pump, HV generator, appliance controller, wherein the powder inlet of podwer gun is connected with the meal outlet of main powder bucket, the powder inlet of arm of dusting is connected with the meal outlet of podwer gun by powder feeding pipe, the powder inlet that the interior recycling cavity of the arm that dusts filters the powder bucket by powder retrieving pipe and recovery is connected, outer recover is in mouthful outside of dusting of the arm that dusts, the meal outlet of outer recover is connected with the powder inlet that reclaims filtration powder bucket by powder retrieving pipe, vavuum pump is connected with the filter that reclaims filtration powder bucket by tracheae, reclaiming the feeding engine that filters powder bucket meal outlet is connected by the powder inlet of powder feeding pipe with main powder bucket, HV generator in the arm that dusts powder and the can body outside the arm that dusts between produce the high-pressure electrostatic electric field, appliance controller is made power supply and control connection with the electrical appliance on the device, and mouthful width that dusts of the arm that dusts is corresponding with the setting coating width of can body weld seam.
The preferred mode of the HV generator of technique scheme is mounted in the arm that dusts, to improve the applicability of its work.
Technique scheme also can be provided with the outer powder bucket of mending, and consumes in order to the powder amount of replenishing main powder bucket, and the feeding engine of mending powder bucket meal outlet outward is connected by the powder inlet of powder feeding pipe with main powder bucket.
The filter that the powder bucket is filtered in the recovery of technique scheme also can be provided with the batch (-type) vibrational structure, in time clears up the powder that adheres on the filter screen.
The beneficial effects of the utility model: owing to adopt one can supply the sheathed arm that dusts thereon of can body as dusting terminal, and can body is to be set in to do operation continuously on the arm that dusts, mouthful width that dusts is corresponding with the weld seam coating width, so can under the high-pressure electrostatic effect, realize the local spraying continuously of can body inwall weld seam, and accuracy height that dusts; Because the amount of powder that escapes is quite few, simultaneously because mouthful outside of dusting of the arm that dusts is provided with outer recover, can filter the powder bucket with in time being recovered to reclaim with the powder that cooperates the slit to overflow of can body from the mouth that dusts, so powder utilization rate height, powder is again wasted seldom, the dirt powder of operating environment pollutes greatly and reduces; Be provided with recycling cavity in the arm is communicated with recovery filtration powder bucket owing to dust, the accumulated powder cleaning in time that can will not be adsorbed on the can body and drop to recycling cavity in the arm that dusts is walked and is recovered to reclaim and filters the powder bucket, arm stops up so effectively prevented to dust, and powder utilization rate height again; Owing to have above-mentioned efficient perfect powder recovery system and good design feature, the utility model can adapt to the application need of the high standard high request of system jar industry.
The utility model is described in further detail below in conjunction with drawings and Examples.
