Description
Technical field
The present invention relates to paint spraying tooling fields.
Background technique
Stereo set probably includes power amplifier, peripheral equipment (including compressor, effect device, balanced device, driver etc.), loudspeaking
Device (speaker, loudspeaker), sound console, sound source (such as microphone, musical instrument, VCD, DVD) show equipment；With people's living standard
Be gradually increased, the pursuit of life is also constantly being promoted, wherein music be even more be favored by people；Therefore, music is played
Sound equipment start to popularize each family.
Currently, the cylindric loudspeaker casing completed the process needs to carry out spray painting processing, the beauty of loudspeaker casing is improved, it is convenient
Later period sells；Simplest japanning mode now are as follows: loudspeaker casing need to be put into the cabinet equipped with paint and impregnated, then
Loudspeaker casing is taken out, the japanning of loudspeaker casing is completed；But the japanning effect of above-mentioned japanning mode loudspeaker casing is uneven, causes
The outer wall of loudspeaker casing will appear male and fomale(M&F), very influence beautiful.
Summary of the invention
It is non-uniform with the japanning for solving current loudspeaker casing the invention is intended to provide a kind of spray-painting plant of loudspeaker casing
Problem.
In order to achieve the above object, base case of the invention is as follows: a kind of spray-painting plant of loudspeaker casing, including hollow
Cabinet, the cabinet is equipped with opening, the sealing plate of sealed opening is hinged in the opening；The lower rotation of the cabinet
It is connected with disk, it is circumferentially equidistant on the disk to be equipped with several limiting slots and swing mechanism, it is slided on each limiting slot
It is connected with limited block, and is equipped with the first spring between limited block and limiting slot；Air bag, and air bag are equipped between the limited block
Several support arms towards at the top of air bag are connected on inner wall；The swing mechanism includes several and the hinged rocking bar of disk,
Second spring is equipped between each rocking bar and disk；It is equipped with sliding slot on each rocking bar, and on sliding slot
Slidably connect recycling bins；Each rocking bar is hinged with hits arm, and hits arm and rocking bar far from one end of disk
Between be equipped with third spring；The bottom of the cabinet is additionally provided with motor, and the motor is equipped with cam；On the side wall of the cabinet
It is slidably connected equipped with guide pad, and on guide pad for the friction arms with loudspeaker casing external wall friction, and friction arms and guiding
The 4th spring is equipped between block, the friction arms offset with cam；The side for squeezing recycling bins is additionally provided in the friction arms
Arm；Spray gun is additionally provided on the side wall of the cabinet.
The principle of base case: when operation, loudspeaker casing is placed on disk through opening, so that limited block and sound equipment shell
The inner wall of body offsets, the first spring elongation；So that air bag is extruded, air bag is vertically swollen in loudspeaker casing for the movement of limited block
It is swollen, increase the contact area of air bag Yu sound equipment inner wall；Also, limited block extruding gasbag rotates support arm, and support arm squeezes
The inner wall of pressuring gasbag and loudspeaker casing offsets (i.e. tensioner), realizes the positioning to loudspeaker casing with this；Meanwhile hits arm and sound equipment
The outer wall of shell offsets.
Motor band moving cam rotates, and the 4th spring of cam engagement can drive friction arms and side arm back and forth to transport in the horizontal direction
It is dynamic；The rotation that loudspeaker casing is realized using friction arms and the external wall friction of loudspeaker casing, the paint effect for recycling spray gun to spray
In on the outer wall of loudspeaker casing, can the outer wall to voice box casing uniformly painted.
When friction arms and the external wall friction of loudspeaker casing, the path of sidewall extrusion recycling bins along the chute is to the direction of hits arm
It is mobile；Since the centrifugal force that loudspeaker casing rotation generates swings rocking bar and hits arm to the direction of cabinet wall, the
Two spring elongations, third spring-compressed；When friction arms disappear to the active force of voice box casing, effect of the rocking bar in second spring
Under, hits arm equal backswing under the action of third spring, the reciprocally swinging of rocking bar and hits arm can be realized；Hits arm
When contacting with loudspeaker casing outer wall, the paint on loudspeaker casing outer wall can be carried out uniformly to polish processing；Also, outside loudspeaker casing
Paint on wall is since gravity can flow downward, and extra paint can flow down in the guiding role of hits arm on loudspeaker casing outer wall
Enter in recycling bins and saves；When hits arm and recycling bins are hit, recycling bins can be made to vibrate, so that being adhered to the oil on recycling chamber interior wall
Paint falls to the bottom of recycling bins.
Limited block cooperates the first spring, rocking bar cooperation second spring to be suitable for various sizes of loudspeaker casing.
The advantages of base case: this programme passes through limit using the linkage of mobile the realization air bag and support arm of limited block
Block, air bag and support arm three position loudspeaker casing, and locating effect is good；Utilize rubbing for friction arms and loudspeaker casing outer wall
The rotation for realizing loudspeaker casing is wiped, spray gun is acted on the loudspeaker casing outer wall of rotation, be can be realized to loudspeaker casing outer wall
Uniform japanning；Also, the paint on loudspeaker casing outer wall can flow downward under gravity, utilize hits arm and sound equipment shell
The contact of body can carry out the bottom of loudspeaker casing outer wall uniformly to polish processing, and can also receive extra paint through hits arm
In collection to recycling bins；Compared to the japanning mode of current loudspeaker casing, the uniform japanning effect of loudspeaker casing outer wall ensure that.
Preferred embodiment one: as the preferred embodiment of basic scheme, the top of the cabinet is equipped with to be positioned for loudspeaker casing
