Examples
The embodiment provides a rail web spraying method for preventing tear marks, which comprises the following steps:
in the process of spraying the primer, before the spraying end point is reached, the spraying pressure is removed, and the primer spraying on the residual length is completed by using the residual pressure.
As shown in FIG. 1, the area a is the predetermined spraying area of the primer, and the two end lines of the area a are line x and line y respectively.
In the process of spraying the primer, spraying may be started from line x and gradually sprayed to line y, the spraying width being the same as the width of the a-region.
In the process of spraying the primer, before the end point of the spraying is reached, that is, when the line z is reached, the spraying pressure is removed, the primer continues to be sprayed due to the excess pressure, and the primer continues to be sprayed by the excess pressure to complete the spraying of the primer over the remaining length (the area from the line z to the line y).
Through the design, the spraying amount of the primer when the primer is close to the spraying tail end (namely the line y) is effectively controlled, and the primer at the tail end is sprayed by adopting the residual pressure, so that the phenomenon that the primer flows downwards to generate tear marks due to the fact that the primer is too much near the line y can be effectively avoided, the attractiveness and the spraying quality of primer spraying are greatly improved, and meanwhile, the using amount of the primer can be effectively saved. The obtained primer coating has better quality, and is more convenient to code on the primer.
On the other hand, the pressure relief is completed while the primer at the tail end is sprayed by adopting the excess pressure, so that compared with a mode of suddenly closing the nozzle, the pressure accumulation can be avoided to damage parts, and the burst type spraying is also avoided when the spraying is started next time.
In general, the rail web spraying method can effectively control the spraying length of the primer, avoids the generation of tear marks, is simple and convenient, is convenient to use and implement, and effectively improves the spraying quality of the rail web.
During use, the remaining length (the area from line z to line y) is determined based on the travel speed of the head along the rail and the relief time required after the spraying pressure is removed (i.e., the time required for the primer to stop spraying after the spraying pressure is removed). The primer can just fill the area a, and the spraying quality is further improved.
In addition, the rail web spraying method for preventing the tear mark further comprises the following steps: after a section of primer is sprayed, namely after the primer spraying of an area a is finished, the initial end of the section of primer is returned, namely the line x at the initial end of the area a is returned, and the code spraying is carried out on the primer from the line x to the line y.
It should be noted that, after a section of primer is sprayed, the initial end of the section of primer is returned to spray the code, so that the accuracy of spraying the code of the section of primer can be more effectively guaranteed. Compared with the mode that the primer of the whole track is completely sprayed and then the code spraying is carried out, on one hand, the difficulty of repeated positioning is reduced, on the other hand, the long-distance reciprocating motion on the whole track is avoided, and the working load is greatly reduced.
After the primer is sprayed for one section, the primer returns to the starting end of the primer, and time is reserved for curing the primer, so that the fusion effect of the primer and the sprayed code can be effectively guaranteed, and the visual effect is better. Compared with the method that the priming paint of the whole track is completely sprayed and then the code spraying is carried out, the method avoids the situation that the priming paint and the code spraying are too abrupt.
It should be noted that the spraying direction may be opposite, that is, the line y may be used as a starting end to spray the coating on the line x, and the spraying direction is not limited, and may be flexibly selected according to actual needs.
Referring to fig. 1 to 5, in order to more conveniently implement the rail web spraying method for preventing the tear mark, the present embodiment further provides a rail web spraying apparatus 1000 for preventing the tear mark, wherein the rail web spraying apparatus 1000 for preventing the tear mark includes: a spray painting assembly 300 and a traveling assembly 200.

Wherein, in the process of spraying the primer, before reaching the spraying end point, namely, when the traveling assembly 200 drives the paint spraying assembly 300 to spray to the line z, the spraying pressure is removed, so that the paint spraying assembly 300 finishes spraying the primer in the remaining length (the area from the line z to the line y) by using the residual pressure.
In this embodiment, the anti-tear rail web spraying device 1000 further includes a control component (not shown in the figure), the paint spraying component 300 and the traveling component 200 are electrically connected to the control component, and the control component is used for controlling the movement of the traveling component 200 and the start and stop of the paint spraying component 300. The control assembly can be used for more conveniently controlling the paint spraying assembly 300 and the traveling assembly 200 to perform the spraying work in a coordinated manner.
In addition, additional functions may be added to the control assembly, such as a preset program, enabling the control assembly to determine the remaining length from the travel speed and the pressure relief time, and/or directly set at least one of the travel speed, the pressure relief time, and the remaining length. Therefore, the controllability of the spraying of the primer is better, and the spraying is more flexible.
Further, the rail web spraying device 1000 for preventing tear marks further comprises a code spraying assembly 400, and the code spraying assembly 400 is used for spraying codes on the primer. After the spraying of the paint spraying assembly 300 finishes a section of primer, the advancing assembly 200 drives the tear-proof rail web spraying device 1000 to return to the starting end of the section of primer, so that the code spraying assembly 400 is used for spraying codes. Namely, the code spraying component 400 and the paint spraying component 300 are simultaneously installed on the anti-tear rail web spraying device 1000, and after the primer spraying of the area a is completed, the code spraying of the area a can be started immediately.
Like this, can ensure the precision of spouting the sign indicating number of this section priming paint more effectively. Compared with the method that the whole priming paint of the whole track is sprayed and the code is sprayed, on one hand, the situation that the positions of different priming paints need to be repeatedly positioned is avoided, the positioning difficulty is reduced, the accuracy of the position of the code is also improved, on the other hand, the long-distance reciprocating on the whole track is also avoided, and the work load is greatly reduced.
The primer is sprayed to the initial end of the primer section, and the primer is cured in a preset time, so that the primer drying time is not too long, the fusion effect of the primer and the sprayed code can be effectively guaranteed, and the visual effect is better. Compared with the method that the priming paint of the whole track is completely sprayed and then the code spraying is carried out, the method avoids the situation that the priming paint and the code spraying are too abrupt.
In addition, to spout a yard subassembly 400 and spray paint subassembly 300 and installed simultaneously on the rail web spraying device 1000 of preventing the tear-off print, this kind of design and "the spraying returns the initiating terminal of this section of priming paint promptly after accomplishing one section of priming paint and spouts a yard" this kind of reciprocating type spraying mode agrees with very much, when accomplishing the priming paint spraying pressure release, the priming paint has sufficient time drying solidification before spouting the yard, the spraying is accomplished one section of priming paint and can be spouted a yard and also can guarantee the vision fusion effect of priming paint and spouting a yard, can also guarantee to spout the accuracy of the position of spouting a yard. Like this, after the web of rail spraying device 1000 of preventing the tear-off print moves to orbital terminal point from orbital starting point, whole orbital priming paint spraying and spout the sign indicating number have all been accomplished, need not to turn back again and go to spout the sign indicating number like traditional means, have improved the efficiency of construction greatly, have improved the spraying quality.
