Each injection mechanical arm 12 is provided with a profiling fixed arm 14, the profiling fixed arm 14 is provided with a plurality of spray guns 15, and the spray guns 15 are used for injecting heat insulation materials on a heat insulation pipeline. The purpose of the contoured retention arm 14 is to accommodate insulated pipes of different cross-sectional shapes and sizes.
The connection mode of the copying fixing arm 14 and the injection mechanical arm 12 is detachable connection, when the production specification is changed, the proper copying fixing arm 14 can be replaced immediately, and after the copying fixing arm 14 is replaced, the position and the number of the spray guns 15 on the copying fixing arm 14 can be adjusted.
Still install film on the workstation 11 and cover module 3, film covers module 3's effect and covers the protection film on the insulating tube, it should be understood, the insulating tube production line disclosed in the embodiment of this application, the insulating material of foaming type is used, also be the insulating material of spray gun 15 spun and fall on the insulating tube after, the volume can increase rapidly, just need apply the one deck film on the insulating material this moment, on the one hand can form the protection to the insulating material, on the other hand can form the restraint to the shape of insulating material, make the insulating tube neat and pleasing to the eye, the thickness of each insulating material also can tend to unanimity simultaneously.
When the film covering module 3 works, the profiling pressing plates 21 and the second driving device 22 are also required to be matched, the number of the profiling pressing plates 21 is two, the profiling pressing plates 21 are symmetrically arranged on the workbench 11 and are in sliding connection with the workbench 11, namely, the distance between the two profiling pressing plates 21 can be increased or reduced, the aim is the same as that of the spraying mechanical arm 12, and the film covering module is suitable for heat-insulating pipelines with different diameters.
The power for moving the copying press plate 21 is provided by the second driving devices 22, the number of the second driving devices 22 is also two, the two second driving devices 22 are both arranged on the workbench 11, and each second driving device 22 is responsible for driving one copying press plate 21 to slide on the workbench 11.
The profiling pressing plate 21 is used for shaping a protective film on the heat preservation pipe, specifically, the film covering module 3 applies pressure to the protective film on the heat preservation pipe, and meanwhile, the heat preservation material between the protective film and the heat preservation pipe can also deform and be solidified and shaped under the action of the pressure.
Combine a specific production process, the heat preservation pipeline that needs plus the heat preservation passes through workstation 11 under the drive of haulage equipment, and through the in-process, the translation rate of heat preservation pipeline is invariable, and here for convenient understanding, still need introduce heat preservation pipeline's haulage equipment.
The transportation equipment of the heat preservation pipeline consists of a guide rail and two transportation trolleys arranged on the guide rail, wherein the two transportation trolleys respectively support two ends of the heat preservation pipeline and drive the heat preservation pipeline to move along the guide rail. In the moving process, the spray gun 15 can spray the heat insulation material on the surface of the heat insulation pipeline, the film covering module 3 can cover the protective film on the surface of the heat insulation material, the profiling pressing plate 21 can shape the heat insulation pipeline with the heat insulation material and the protective film, and in the shaping process, the shape of the heat insulation material changes and the curing process is completed at the same time.
Specifically, the thermal insulation pipeline moves slowly through the workbench 11, in the process, the two first driving devices 13 respectively push the two spraying mechanical arms 12 to move towards the direction close to the thermal insulation pipeline, and meanwhile, the two second driving devices 22 respectively push the two copying pressing plates 21 to move towards the direction close to the thermal insulation pipeline.
After the heat preservation pipeline moves to the starting position, the spray guns 15 on the copying fixing arm 14 start to work, heat preservation materials are sprayed on the outer wall of the heat preservation pipeline, the shape of the copying fixing arm 14 is similar to that of the outer wall of the heat preservation pipeline, therefore, the distances between the spray guns 15 on the copying fixing arm 14 and the heat preservation pipeline are the same, and the heat preservation materials can be uniformly sprayed on the outer wall of the heat preservation pipeline.
Then, the film covering module 3 covers the protective film on the heat insulating material on the outer wall of the heat insulating pipe, and the volume of the heat insulating material expands in the process.
Then, the profiling pressing plate 21 applies a pressure to the protective film on the thermal insulation material, and the pressure can limit the shape of the thermal insulation material which is expanding, that is, the profiling pressing plate 21 forms a bound space in the outer space of the thermal insulation pipeline, the thermal insulation material in the bound space can be shaped, and in the shaping process, the thermal insulation material can also complete the curing process at the same time.
Along with the removal of insulating tube, spraying, moulding and solidification process constantly go on, and after insulating tube had the starting position to move the stop position, the even heat preservation of thickness can appear on the surface.
Referring to fig. 1, 3 and 4, as an embodiment of the thermal insulation pipe production line provided by the application, an air hole 23 is added on the profiling pressing plate 21, and a negative pressure device 24 is used, wherein the negative pressure device 24 is installed on the worktable 11 and connected with the air hole 23 and is used for adsorbing the protective film on the inner wall of the profiling pressing plate 21.
It should be understood that the protective film is generally made of plastic film, and the protective film made of such material is soft in texture, and needs to be manually attached when the protective film is initially attached to the heat insulation material, or the protective film is naturally adsorbed on the heat insulation material which is not solidified, obviously, the working efficiency of the first mode can be reduced, and the potential quality defect problem exists in the second mode because the protective film is uncontrollable at the initial position.
After the air hole 23 and the negative pressure device 24 are used, before the copying pressing plate 21 moves towards the heat preservation pipeline, a worker can attach a part of the protective film to the inner wall of the copying pressing plate 21, at the moment, the negative pressure device 24 is started, the protective film can move along with the movement of the copying pressing plate 21, and the relative position of the protective film and the copying pressing plate 21 cannot be changed in the moving process. After the copying pressing plate 21 moves to the designated position, a gap exists between the protective film on the inner wall and the heat insulation pipeline, the gap is filled by the heat insulation material, the protective film is adhered to the heat insulation material in the filling process, and at the moment, the negative pressure device 24 stops working.
Along with the movement of the heat preservation pipeline, the protective film can be uniformly stuck on the heat preservation material on the outer wall of the heat preservation pipeline.
From the production perspective, in the preparation process, the staff need paste the protection film on the inner wall of profile modeling clamp plate 21, and this in-process, the position that the protection film can be guaranteed to the mode of artifical laminating is accurate, simultaneously owing to used the negative pressure to adsorb, the protection film is at the in-process along with profile modeling clamp plate 21 removes, also can not change with profile modeling clamp plate 21's relative position.
And since the copying press plate 21 has two positions, which are referred to as a preparation position and a working position for convenience of description herein, respectively, a worker performs the work of adsorbing the protective film at the preparation position, which has a large operation space and is more convenient to work.
The negative pressure device 24 is composed of a negative pressure pipeline 241, a vacuum unit 242, a hose 243 and the like, wherein the negative pressure pipeline 241 is installed on the profiling pressing plate 21 and communicated with the air hole 23, the vacuum unit 242 is installed on the workbench 11, and two ends of the hose 243 are respectively connected with the input ends of the pipeline 241 and the vacuum unit 242.
When the vacuum unit 242 is in operation, air in the negative pressure pipe 241 and the hose 243 is evacuated to form a negative pressure between the inner wall of the copying press plate 21 and the protective film, so that the protective film can be adsorbed on the inner wall of the copying press plate 21.
Furthermore, the negative pressure pipe 241 is provided with a long hole, the long hole is attached to the outer wall of the profiling pressure plate 21 to form a connecting area 244, and the connecting area 244 is communicated with the air hole 23 in the coverage area.
Referring to fig. 5, as a specific embodiment of the heat preservation pipe production line provided by the application, the profiling fixing arm 14 and the spraying mechanical arm 12 are adjusted to be in sliding connection, and a third driving device 16 is added on the spraying mechanical arm 12, and the third driving device 16 is used for driving the working end of the spray gun 15 to extend between the heat preservation pipe and the profiling pressing plate 21.
In some possible implementations, the third drive 16 uses a pneumatic cylinder.
It should be understood that the spray gun 15 generates a certain amount of sputtering during the process of spraying the insulation material on the outer wall of the insulation pipe, and referring to fig. 6(a) and 6(B), on one hand, the production environment in the workshop is polluted, on the other hand, waste is caused, and therefore, the work order of the spray gun 15 is pushed between the insulation pipe and the profiling pressing plate 21.
The inner wall of the profiling pressure plate 21 is provided with a protective film which is not in direct contact with the heat insulation material sprayed by the spray gun 15, and can play a great role in blocking, so that the heat insulation material can only expand in the relatively closed area.
From another perspective, compared with the method of extruding and molding the thermal insulation material after waiting for the thermal insulation material to expand, it is obvious that the production method of expanding the thermal insulation material after constructing a space is more suitable, because the potential damage of the extrusion to the protective film can be reduced.
Because the production mode is that the protective film is pushed to the designated position firstly, then the thermal insulation material is sprayed between the protective film and the thermal insulation pipeline on the premise of imposing the constraint, then the thermal insulation material is waited to expand, and in the expansion process of the thermal insulation material, the profiling pressing plate 21 and the protective film can be kept still relatively, so that the potential damage to the protective film can be further reduced.
Further, a baffle 151 is additionally arranged at the working end of the driving spray gun 15, and the baffle 151 can also enter between the heat preservation pipe and the profiling pressing plate 21 to intercept heat preservation materials sputtered in the spraying process.
