Description

Spraying marking device and spraying marking equipment

Technical Field

The application relates to the technical field of spraying equipment, in particular to a spraying and scribing device and spraying and scribing equipment.

Background

In the prior art, when marking on the ground (such as traffic sign lines, parking space lines and the like), the beautiful line paper needs to be manually stuck on the ground firstly, then the beautiful line paper is manually rolled and coated or sprayed by a spray gun, so that a line with a clear boundary is formed, the beautiful line paper is torn off after the coating is dried, and the existing marking mode has low efficiency.

Some marking machines are also available in the market, but the marking boundaries of the existing marking machines are not clear, and the marking machines also need to be assisted by the masking paper, when a preset marking path is close to a wall body or a column body, due to the limitation of the structural volume of the marking machines, the marking machines can possibly interfere with the wall body or the column body, and the line close to the wall body or the column body cannot be marked according to the preset marking path.

Disclosure of Invention

The application aims at providing a spraying marking device and spraying marking equipment to solve the problem that the wall column is not convenient to be attached to and the spraying line with clear boundary is quickly formed in the prior art.

The embodiment of the application is realized as follows:

in a first aspect, an embodiment of the present application provides a spray painting line device, which includes:

a frame;

the spray gun is arranged on the frame;

the left baffle and the right baffle are arranged on the rack and positioned on the left side and the right side of the spray gun, the left baffle and the right baffle are arranged oppositely to limit the width of a spraying line, at least one of the left baffle and the right baffle is an obliquely arranged baffle, and the distance between the lower end of the obliquely arranged baffle and the center line of the spray gun is greater than the distance between the upper end of the obliquely arranged baffle and the center line of the spray gun.

In the spraying marking device that this application provided, left baffle and right baffle are installed to the left and right sides at the spray gun, and the spraying scope is restricted by left baffle and right baffle and forms fixed marking width about the spray gun, and that is also the spraying line will form between left baffle and right baffle, and the coating fog grain that surpasss marking width will all be sheltered from by left baffle and right baffle to can form the spraying line that the edge does not have in disorder spraying point, the border is clear. Because at least one of the left baffle or the right baffle is set to be the inclined baffle, in the moving process, compared with the vertically arranged baffle, the whole plate surface of the vertically arranged baffle is close to the wall surface, once the baffle contacts the wall surface, large-area interference can occur, larger friction force can be generated, and the whole device can not move continuously; and the baffle that this application's slope set up is the lower extreme at most and contacts the wall, and the interference scope is little, frictional force is little, is difficult to influence the device global movement. And, this inclined baffle outwards stretches out a distance, and this makes the spraying scope move to one side of frame by the middle part of frame, that is to say, predetermine under the unchangeable condition of the relative distance of marking off route and wall post, the frame can keep away from the wall post relatively, and the frame is difficult to interfere with the wall post of neighbouring to can mark out the spraying line of closing close to the wall post relatively.

The application provides a spraying marking device, through left baffle and the right baffle of at least one kind slope of both sides installation at the spray gun to can form the clear spraying line in boundary, and the wall body is still pressed close to relatively more to the spraying line, solve the problem of being not convenient for press close to the quick clear spraying line in boundary of forming of wall post.

In an embodiment of the present application, optionally, the left baffle and the right baffle are both obliquely arranged baffles.

In above-mentioned technical scheme, left baffle and right baffle all incline to set up and form big end down's loudspeaker shape, when spraying marking device was drawn a line in the left and right sides respectively along same direction, can both make the frame keep away from the wall post, are favorable to spraying marking device to remove and form the spraying line of pressing close to the wall post.

The natural spraying scope of spray gun is big end down's toper, and behind the spray gun set up left baffle and right baffle, certain width of left baffle and right baffle intercepting is within the toper scope, and this width is the actual spraying scope of spray gun to obtain definite marking off width, in above-mentioned technical scheme, left baffle hoist mechanism and right baffle hoist mechanism can adjust and control the marking off border, thereby the adjustment is marked off the width. When the baffle plate is close to the ground, the baffle plate shields the conical range more; when the baffle is far away from the ground, the shielding of the conical range by the baffle is reduced. Therefore, when the left baffle lifting mechanism lifts the left baffle, the scribing width is increased to the left, and when the right baffle lifting mechanism lifts the right baffle, the scribing width is increased to the right. By last, can adjust the width of ruling through setting up left baffle hoist mechanism and right baffle hoist mechanism, the spraying marking device that this application provided can draw out the spraying line that the width is different.

In an embodiment of the present application, optionally, the lifting direction of the left baffle lifting mechanism is parallel to the tilting direction of the left baffle, and the lifting direction of the right baffle lifting mechanism is parallel to the tilting direction of the right baffle.

In above-mentioned technical scheme, its corresponding baffle is promoted to baffle hoist mechanism slant to not only can adjust when the baffle is promoted and rule the width, when baffle and wall post have small intersection, probably lead to interfering, the slant promotes and to make the baffle inwards take in, thereby dodge the wall post, further solve the problem that can't draw the spraying line that presses close to wall body or cylinder according to the marking off route of predetermineeing.

In an embodiment of the present application, optionally, a material receiving groove is provided on one side of the left baffle plate and one side of the right baffle plate facing the spray gun.

Generally, the coating mist particles intercepted on the left baffle and the right baffle do not flow down to the ground, and the flowability may be lost, but when the spraying and marking device works for a long time, the coating mist particles on the left baffle and the right baffle are more and may be gathered and flow down, which may cause the clear boundary influence, and in this case, the machine needs to be stopped for cleaning. In the technical scheme, when the coating fog particles intercepted on the baffle are less, the coating fog particles cannot flow downwards completely, and the coating which flows downwards on the inner side of the baffle can be collected by the material receiving groove arranged on one side of the baffle close to the spray gun, so that the coating is further prevented from dripping to influence the clear boundary, and the problem that the boundary of a spraying line is not clear is solved. Moreover, due to the fact that the material receiving groove is formed, the coating flowing downwards is accommodated by the material receiving groove, the spraying and marking device can support long-time work, the shutdown times are reduced, and the marking efficiency is improved.

In an embodiment of the present application, optionally, a plurality of receiving troughs with different heights are disposed on each of the left baffle 310 and the right baffle 320.

Furthermore, the appearances of the terms "first," "second," and the like in the description herein are only used for distinguishing between similar elements and are not intended to be construed as indicating or implying relative importance.

Examples

As shown in fig. 1, the spraying and line marking apparatus provided in the embodiment of the present application includes a movable body 10 and a spraying and line marking device 30, the spraying and line marking device 30 is provided with a spray gun 200, the movable body 10 is configured to drive the spraying and line marking device 30 to move in a front-back direction, and at this time, the spray gun 200 sprays paint on the ground to form a spraying line in the front-back direction on the ground.

The movable body 10 is provided with a slide seat 20, a frame 100 of the spraying and marking device 30 is installed on the slide seat 20, and the slide seat 20 can drive the spraying and marking device 30 to move left and right on the movable body 10.

When the preset marking path is close to the wall column, the slide carriage 20 drives the spraying and marking device 30 to move left and right, so that the spraying and marking device 30 is close to the wall column, the movable machine body 10 can be kept away from the wall column as far as possible, and the movable machine body 10 is prevented from interfering with the wall column.

As shown in fig. 2, when the preset marking path is close to the wall pillar on the left side of the moving body 10, the slide carriage 20 drives the spraying and marking device 30 to move to the left side of the moving body 10, and the moving body 10 moves forward to drive the spraying and marking device 30 to mark on the left side.

As shown in fig. 3, when the preset scribing path is close to the wall on the right side of the moving body 10, the slide 20 drives the spraying and scribing device 30 to move right to the right side of the moving body 10, and the moving body 10 moves forward to drive the spraying and scribing device 30 to scribe lines on the right side.

The natural spray range of the spray gun 200 is a tapered range, the spray range may be larger than the scribe width, and since most of the paint mist particles are sprayed in the tapered range, but the spray directions of some paint mist particles are in other directions, scattered dots may exist on the left and right sides of the spray line formed during natural spray, and the left and right boundaries may be unclear.

In the prior art, in order to obtain a spraying line with clear left and right boundaries, the beautiful line paper is generally adhered manually, and after the coating is dried completely, the beautiful line paper is torn off, so that the mode is low in efficiency.

In this embodiment, the left and

right baffles

310 and 320 are disposed on the painting and line drawing device 30, as shown in fig. 4, the left and

right baffles

310 and 320 are respectively mounted on the frame 100, the spray gun 200 is located between the left and

right baffles

310 and 320, and the left and

right baffles

310 and 320 are oppositely disposed on the left and right sides of the spray gun 200.

The left baffle 310 and the right baffle 320 can shield paint fog particles, the actual spraying range of the spray gun 200 is limited between the left baffle 310 and the right baffle 320, the distance between the lower ends of the left baffle 310 and the right baffle 320 defines a scribing width, and the paint beyond the scribing width is intercepted by the left baffle 310 and the right baffle 320, so that a spraying line without scattered paint points at the edge can be formed, and a spraying line with clear boundaries is obtained.

The spraying and marking device 30 provided by the embodiment can form a spraying line with a clear boundary only by moving the spraying step, and does not need preparation work before marking and does not need work after marking, so that the working efficiency is greatly improved, and the labor is saved.

In addition, because the mobile machine body 10 has a large structural volume, and other functional devices may be carried on the mobile machine body 10 at times, the spraying and line drawing device is likely to interfere with the wall column during movement, so that a preset line drawing path cannot be installed to be close to the wall column line drawing.

To address this problem, one of the left or

right baffles

310, 320 may be provided as an inclined baffle with its lower end away from the centerline of the lance 200.

For example, the left baffle 310 is set to an inclined baffle, which causes the spray width defined by the left baffle 310 and the right baffle 320 to move a distance to the left of the rack 100 relative to the middle of the rack 100, thereby making it possible to draw a spray line closer to the left sidewall column.

In the scribing operation shown in fig. 2, the painting and scribing device 30 is disposed on the left side of the movable body 10, and the left side barrier is extended to the left side with respect to the machine frame 100 (or the movable body 10 connected to the machine frame 100) by a certain distance, so that the painting width defined by the left barrier 310 and the right barrier 320 can be closer to the left wall stud.

The middle and upper portions of the wall stud often have local protrusions, such as equipment boxes mounted in the middle of the wall stud, pipes mounted in the upper portion of the wall stud, etc., which may also prevent the mobile body 10 from continuing to move the scribe lines along the wall stud.

The spraying and line drawing device 30 provided by the embodiment can solve the problem that when a wall column protrudes during the line drawing work in fig. 2, a certain space is left above the obliquely arranged left baffle 310, so that the movable body 10 and the rack 100 are relatively far away from the wall column, and therefore, the spraying line close to the wall column can be smoothly completed by avoiding the protrusion on the surface of the wall column.

If only the left baffle 310 is set to be inclined, when the right spraying line in fig. 3 needs to be formed, the spraying and line drawing device can be turned in the state in fig. 2, that is, the movable body 10 turns around to travel and moves backward, and at this time, the effect of line drawing close to the wall column and the effect of avoiding local protrusion on the surface of the wall column can be achieved as well.

The left baffle 310 is inclined, when the right baffle 320 is inclined, the principle is the same, and the left and right directions can be changed, and it should be understood by those skilled in the art that the details are not described herein.

In this embodiment, the left baffle 310 and the right baffle 320 are both inclined baffles, and as shown in fig. 4, the left baffle 310 and the right baffle 320 have a small upper end distance and a large lower end distance, and are in a horn shape with a small upper end and a large lower end. When the left and right wall posts need to be pasted and scribed, the slide base 20 is used for driving the spraying and scribing device 30 to switch the left and right positions.

Since the left and

right shutters

310 and 320 may protrude out of the housing 100, if the left and right shutters accidentally collide with the obstacle during movement, they may be easily deformed or bent, and the deformed shutters may affect the shape of the boundary of the scribe line and may also affect the scribe line width. In order to improve the rigidity of the baffle and relieve the problem that the baffle collides with obstacles and deforms, folding edges are formed at the front end and the rear end of the baffle.

Referring to fig. 4 and 5, it can be seen that the left and

right baffles

310 and 320 respectively have front folded edges 510 in fig. 4, and the left and

right baffles

310 and 320 respectively have rear folded edges 520 in fig. 5.

After the hem is arranged, if the baffle conflicts obstacles in the front-back direction, the obstacles firstly contact the hem, and then the hem firstly replaces the baffle to deform under stress, so that the problem of baffle deformation is relieved.

If the baffle receives the power of left and right direction, if do not have the hem, the baffle can upwards buckle, and have the hem back, when the baffle has the trend of warping, the hem will be drawn, increase the ability that the baffle resisted upwards buckling, alleviate the problem that the baffle warp.

In general, the coating material mist particles intercepted by the left and

right baffles

310 and 320 may have lost fluidity without flowing down to the ground, but when the painting and line drawing device 30 is operated for a long time, the coating material mist particles on the left and

right baffles

310 and 320 are more and may be gathered and flow down, which may affect the clear boundary, and in this case, the machine needs to be stopped for cleaning.

In order to avoid the influence of the paint flowing down by the collected paint on the boundary definition of the spraying line, a receiving groove 610 is formed on the inner side of the lower end of the baffle, as shown in fig. 6, fig. 6 shows a schematic cross-sectional view of the receiving groove 610, and the receiving groove 610 extends along the front-back direction to receive the paint flowing down on the inner side of the baffle so as to prevent the paint from dropping to the ground.

As can be seen from fig. 5 and 6, the closer to the lower end of the baffle plate, the more paint is intercepted on the inner surface of the baffle plate, and therefore, a plurality of receiving grooves 610 having different heights are provided on each baffle plate. The plurality of receiving grooves 610 with different heights achieve the effect of collecting the coating layer by layer, further increase the collection amount, and prolong the single working time of the spraying and scribing device 30.

The receiving groove 610 may be formed by pressing or molding on the inner side surface of the baffle plate, or may be formed in other manners.

In this embodiment, connect silo 610 to form by connecting the inboard flitch that connects of baffle, connect the flitch crooked, and the lower extreme that connects the flitch connects corresponding baffle in order to form the ascending silo 610 that connects of opening, for further preventing to leak the material, connect the hem that its corresponding baffle is connected at both ends around the flitch to further form the confined silo 610 that connects.

The material receiving plate can be bent into an L shape, a U shape, a V shape and the like. The material receiving plate in this embodiment is an L-shaped plate 600.

The L-shaped plate 600 includes a bottom plate and a side plate, wherein the bottom plate is connected to the inner side of the baffle, the side plate is spaced from the inner side of the baffle, and the space is used for receiving the paint flowing down.

The two ends of the L-shaped plate 600 are optionally connected with the front folding edge 510 and the rear folding edge 520 respectively to form a material receiving groove 610 with two closed ends.

After the material receiving groove 610 is arranged, the coating material flowing downwards is accommodated by the material receiving groove 610, so that the spraying and scribing device 30 can support long-time work, the shutdown times are reduced, and the scribing efficiency is improved.

And, the L-shaped plate 600 can also support the front folding edge 510 and the rear folding edge 520, further improving the rigidity of the left baffle 310 and the right baffle 320.

To facilitate cleaning of the panels, the L-shaped panels 600 are optionally removably attached to the respective panels and their front and

rear flanges

510, 520.

For example, guide grooves are formed in the front and

rear flanges

510 and 520, and both ends of the bottom plate of the L-shaped plate 600 can be inserted into the front and rear guide grooves, so that one side of the bottom plate, which is far away from the side plates, can abut against the inner side surface of the baffle plate, thereby forming the receiving groove 610.

Furthermore, a slot is formed on the inner side surface of the baffle plate, so that one side of the bottom plate, which is far away from the side plate, can be inserted into the slot, and one side of the bottom plate, which is far away from the side plate, is matched with the slot.

Further, one side of the bottom plate, which is far away from the side plate, is covered with a rubber layer so as to further seal a connecting gap between the bottom plate and the slot, thereby preventing the paint from seeping downwards.

In actual scribing applications, generally, a longer spray line requires a relatively lower degree of definition for the front and rear boundaries, but a shorter spray line often requires a clear front and rear boundary.

In order to form a clear front-rear boundary, the coating and scribing device 30 further includes a front baffle 330 and a rear baffle 340, the front baffle 330 and the rear baffle 340 are located on the front and rear sides of the spray gun 200, and the front baffle 330 and the rear baffle 340 are disposed opposite to each other.

The front and

rear baffles

330 and 340 define a spray range in the front and rear direction of the spray gun 200, and intercept front and rear scattered mist particles, so that both ends of the spray line can have a clear boundary.

Under the limit of preceding baffle 330, backplate 340, left baffle 310 and right baffle 320, the spraying marking equipment forms the closed spraying scope in all around, can intercept effectively the direction unpredictable scattered fog grain, for example from the rear jet-out but fall on the scattered fog grain of spraying line left and right sides along the arc route, play the effect that further promotes the clear degree in spraying line boundary.

In order to prevent the front and

rear shutters

330 and 340 from scratching the coating which has just been sprayed onto the ground while moving, if the coating on the ground is scratched, the definition of the boundary of the spray line may be affected. Further, the front baffle 330 and the rear baffle 340 form a gap with the ground, thereby further ensuring that the coating line boundary is clear.

In actual scribing work, the required scribing width may be different under different application scenarios. The spraying and line drawing device 30 provided by the embodiment is provided with a baffle lifting mechanism, and the heights of the left baffle 310 and the right baffle 320 are adjusted by the baffle lifting mechanism, so that the line drawing width is adjusted.

As described above, the natural spray range of the spray gun 200 is tapered, and the left and

right baffles

310 and 320 are cut to a certain width within the tapered range, so as to obtain the actual spray range of the spray gun 200, and obtain the determined scribe width.

When the baffle plate is close to the ground, the baffle plate shields the conical range more; when the baffle is far away from the ground, the shielding of the conical range by the baffle is reduced. Therefore, the baffle lifting mechanism controls the scribing width by lifting the baffle and lowering the baffle.

For ease of understanding, referring to fig. 5, the front baffle 330 and the front flap 510 are hidden from view in fig. 5 to enable the actual spray width range to be seen, and the dotted lines indicate the actual spray width range.

In fig. 5, the left baffle 310 and the right baffle 320 are both close to the ground, the tapered range is intercepted from the middle of the waist line, the width of the spraying line is narrow, and if the baffles are lifted for a certain distance, the width of the spraying line can be relatively increased.

In this embodiment, the shutter lifting mechanism includes a left shutter lifting mechanism 410 and a right shutter lifting mechanism 420 to control the left and right spray ranges, respectively.

As shown in fig. 7, after the left flapper lifting mechanism 410 lifts the left flapper 310, the partial shielding range is released, the left side painting range is increased, and the width of the painting line is widened to the left side.

As shown in fig. 8, after the right shutter 320 is lifted by the right shutter lifting mechanism 420, the partial shielding range is released, the spraying range on the right side is increased, and the width of the spraying line is widened to the right side.

In the spraying and marking process, the situation that the surface of the lower part of the wall column is locally and horizontally protruded due to construction reasons can be encountered, and the protrusion can slightly intersect with the baffle plate and interfere with the advance to influence the moving and marking.

In order to solve the problem that the small bulges on the wall surface interfere the marking work, the lifting and descending directions of the baffle lifting mechanism are set to be parallel to the inclined directions of the corresponding baffles. When the baffle lifting mechanism lifts the baffle, the baffle can be retracted inwards, so that the wall column is avoided, and the marking operation can be smoothly carried out.

Because the protrusions on the surface of the lower part of the wall column are small, the lifting height is small, the influence on the width of the marking line is small, and the boundary definition of the spraying line is not influenced.

Referring to fig. 7 and 8, the lifting direction of the left flap lifting mechanism 410 is parallel to the tilting direction of the left flap 310, and the lifting direction of the right flap lifting mechanism 420 is parallel to the tilting direction of the right flap 320.

When the left baffle plate 310 is lifted by the left baffle plate lifting mechanism 410, the left baffle plate 310 can be horizontally retracted to the right side in the lifting process.

When the right baffle lifting mechanism 420 lifts the right baffle 320, the right baffle 320 can be horizontally retracted to the left side in the lifting process.

In this embodiment, the left baffle lifting mechanism 410 and the right baffle lifting mechanism 420 are both cylinders, the cylinders are installed on the frame 100, and piston rods of the cylinders are fixedly connected to the corresponding baffles.

The left baffle 310 and the right baffle 320 are respectively provided with a connecting lug 800 and a sliding sleeve 700. The piston rod of the left cylinder is fixedly connected with the connecting lug 800 on the left baffle 310, and the whole left cylinder can slide in the sliding sleeve 700. The piston rod of the right cylinder is fixedly connected with the connecting lug 800 on the right baffle 320, and the whole right cylinder can slide in the sliding sleeve 700. The sliding sleeve 700 and the air cylinder are matched to play a role in guiding, so that the lifting is more stable.
