Detailed Description
The technical scheme in the application is further described in detail below with reference to the accompanying drawings.
Referring to fig. 1, in order to disclose a production line of insulation pipes according to an embodiment of the present application, the production line is composed of a workbench 11, an injection mechanical arm 12, a first driving device 13, a profiling fixing arm 14, a spray gun 15, a third driving device 16, a profiling pressing plate 21, a second driving device 22, a film covering module 3, and the like, wherein two injection mechanical arms 12 are installed on the workbench 11, and the two injection mechanical arms 12 are symmetrically installed on the workbench 11 and slidingly connected with the workbench 11, that is, the distance between the two injection mechanical arms 12 can be increased or reduced, so that the purpose is to adapt to insulation pipes with different diameters.
Referring to fig. 1 and 2, the power of the moving of the spraying robot 12 is provided by two first driving devices 13, and the two first driving devices 13 are mounted on the workbench 11, and each first driving device 13 is responsible for driving one spraying robot 12 to slide on the workbench 11.
In some possible implementations, the first drive 13 uses an electric cylinder.
Each spraying mechanical arm 12 is provided with a profiling fixing arm 14, the profiling fixing arm 14 is provided with a plurality of spray guns 15, and the spray guns 15 are used for spraying heat insulation materials on the heat insulation pipeline. The purpose of the contoured securing arms 14 is to accommodate insulated pipes of different cross-sectional shapes and sizes.
The connection mode of the profiling fixing arm 14 and the spraying mechanical arm 12 is detachable connection, when the production specification changes, the proper profiling fixing arm 14 can be replaced immediately, and after the profiling fixing arm 14 is replaced, the positions and the number of the spray guns 15 on the profiling fixing arm 14 can be adjusted together.
The workbench 11 is also provided with the film covering module 3, the film covering module 3 is used for covering a protective film on the heat insulation pipe, and it is understood that the heat insulation pipe production line disclosed by the embodiment of the application uses the foaming type heat insulation material, namely, after the heat insulation material sprayed by the spray gun 15 falls on the heat insulation pipe, the volume can be rapidly increased, and at the moment, a layer of film is required to be applied on the heat insulation material, so that on one hand, the heat insulation material can be protected, on the other hand, the shape of the heat insulation material can be restrained, the heat insulation pipe is tidy and attractive, and meanwhile, the thickness of the heat insulation material at all positions can be consistent.
When the film covering module 3 works, the profiling pressing plates 21 and the second driving device 22 are matched, the number of the profiling pressing plates 21 is two, the profiling pressing plates 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, and the purpose is the same as that of the spraying mechanical arm 12, so that the film covering module is suitable for heat preservation pipelines with different diameters.
The power for moving the profiling platen 21 is provided by the second driving devices 22, the number of the second driving devices 22 is 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 profiling platen 21 to slide on the workbench 11.
The profiling pressing plate 21 is used for shaping a protective film on the heat-insulating pipe, specifically, applying pressure to the protective film applied on the heat-insulating pipe by the film covering module 3, and meanwhile, the heat-insulating material between the protective film and the heat-insulating pipe is deformed and solidified under the action of the pressure.
In combination with a specific production process, the heat-insulating pipeline with an additional heat-insulating layer is driven by the transportation device to pass through the workbench 11, and the moving speed of the heat-insulating pipeline is constant in the process, so that the heat-insulating pipeline is convenient to understand, and the transportation device of the heat-insulating pipeline is also required to be introduced.
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 the 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 sprays heat insulation materials on the surface of the heat insulation pipeline, the film covering module 3 covers a protective film on the surface of the heat insulation materials, the profiling pressing plate 21 molds the heat insulation pipeline with the heat insulation materials and the protective film, and in the molding process, the shape of the heat insulation materials changes and simultaneously the curing process is completed.
Specifically, the thermal insulation pipeline slowly passes through the workbench 11 in the moving process, in this process, the two first driving devices 13 respectively push the two spraying mechanical arms 12 to move towards the direction approaching the thermal insulation pipeline, and meanwhile, the two second driving devices 22 respectively push the two profiling pressing plates 21 to move towards the direction approaching the thermal insulation pipeline.
After the thermal insulation pipeline moves to the starting position, the spray guns 15 on the profiling fixing arms 14 start to work, thermal insulation materials are sprayed on the outer wall of the thermal insulation pipeline, the profiling fixing arms 14 are similar to the outer wall of the thermal insulation pipeline in shape, therefore, the distances between the spray guns 15 on the profiling fixing arms 14 and the thermal insulation pipeline are the same, and the thermal insulation materials can be uniformly sprayed on the outer wall of the thermal insulation pipeline.
Then, the film covering module 3 covers the thermal insulation material on the outer wall of the thermal insulation pipeline with a protective film, and during this process, the volume of the thermal insulation material expands.
Then, the profiling platen 21 will apply a pressure to the protective film on the insulation material, which pressure can limit the shape of the insulation material being expanded, that is, the profiling platen 21 will form a binding space in the outer space of the insulation pipe, the insulation material located in the binding space will be shaped, and the curing process will be completed simultaneously during the shaping process.
Along with the movement of the heat-preserving pipeline, the spraying, shaping and curing processes are continuously carried out, and after the heat-preserving pipeline is moved from the starting position to the stopping position, a heat-preserving layer with uniform thickness can be formed on the outer surface.
Referring to fig. 1, 3 and 4, as a specific embodiment of the production line of insulation pipe provided by the application, an air hole 23 is added on the profiling platen 21, and a negative pressure device 24 is used, and the negative pressure device 24 is installed on the workbench 11 and connected with the air hole 23, and is used for adsorbing the protection film on the inner wall of the profiling platen 21.
It should be understood that, in general, plastic films are used as the protective film, and the protective film made of such materials is soft, and needs to be attached manually when the protective film is attached to the insulating material at the beginning, or the protective film is naturally adsorbed on the insulating material which is not solidified and formed, so that the working efficiency of the first mode is obviously reduced, and the second mode has potential quality defect problem 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 profiling pressing plate 21 moves to the heat preservation pipeline, a part of the protective film can be attached to the inner wall of the profiling pressing plate 21 by a worker, at the moment, the negative pressure device 24 is started, the protective film can move along with the movement of the profiling pressing plate 21, and the relative position of the protective film and the profiling pressing plate can not change in the moving process. After the profiling pressing plate 21 moves to a 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 adhered to the heat preservation material on the outer wall of the heat preservation pipeline.
From the perspective of production, in the preparation process, the staff needs to paste the protection film on the inner wall of profiling clamp plate 21, and this in-process, the mode of artifical laminating can guarantee that the position of protection film is accurate, simultaneously owing to used negative pressure to adsorb, the protection film can not change at the in-process along with profiling clamp plate 21 removes with profiling clamp plate 21's relative position yet.
And since the profiling platen 21 has two positions, which are referred to herein as a ready position and a working position, respectively, for convenience of description, a worker completes the adsorption work of the protective film at the ready position, and the operation space at the position is large, and the work is also more convenient.
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 arranged on the profiling pressing plate 21 and is communicated with the air hole 23, the vacuum unit 242 is arranged on the workbench 11, and two ends of the hose 243 are respectively connected with the pipeline 241 and the input end of the vacuum unit 242.
In the operation of the vacuum unit 242, air in the negative pressure pipe 241 and the hose 243 is drawn out, and negative pressure is formed between the inner wall of the profiling platen 21 and the protective film, so that the protective film can be adsorbed on the inner wall of the profiling platen 21.
Further, the negative pressure pipe 241 is provided with a long hole, and the long hole is attached to the outer wall of the profiling pressing plate 21 to form a connection area 244, and the connection area 244 is communicated with the air hole 23 in the coverage area.
Referring to fig. 5, as a specific embodiment of the thermal insulation 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, meanwhile, 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 into between the thermal insulation pipe and the profiling pressing plate 21.
In some possible implementations, the third drive 16 uses a cylinder.
It should be understood that, during the process of spraying the insulating material on the outer wall of the insulating pipe, the spray gun 15 will generate a certain amount of sputtering, referring to fig. 6 (a) and 6 (B), on one hand, the production environment in the workshop will be polluted, and on the other hand, waste will be caused, so that the work sheet of the spray gun 15 is pushed between the insulating pipe and the profiling platen 21.
The inner wall of the profiling pressing plate 21 is provided with a protective film which is not in direct contact with the thermal insulation material sprayed out of the spray gun 15, and can also play a great role in blocking, so that the thermal insulation material can only expand in the relatively closed area.
From another perspective, it is apparent that the method of producing the insulation material by expanding it after constructing a space is more suitable than the method of extruding the insulation material after expanding it, because the potential damage to the protective film by extrusion molding can be reduced.
Because this production method is to push the protection film to the appointed position at first, then spray the thermal insulation material between protection film and heat preservation pipeline under the prerequisite of exerting the constraint, wait for thermal insulation material inflation again, in the thermal insulation material inflation process, can also keep relatively still between profile modeling clamp plate 21 and the protection film, can further reduce the potential damage that the protection film probably receives.
Further, a baffle 151 is added on the working end of the driving spray gun 15, and the baffle 151 can also enter between the heat insulation pipe and the profiling pressing plate 21 to intercept the heat insulation material sputtered in the spraying process.
Referring to fig. 1, as a specific embodiment of the insulating tube production line provided by the application, the film covering module 3 is composed of two half rings 31, fixing arms 32, fourth driving devices 33, and the like, the two half rings 31 are symmetrically arranged on the workbench 11 and slidably connected with the workbench 11, power for moving the half rings 31 is provided by the fourth driving devices 33, the number of the fourth driving devices 33 is also two, the two fourth driving devices 33 are all installed on the workbench 11, and each fourth driving device 33 is responsible for driving one half ring 31 to slide on the workbench 11.
In some possible implementations, the fourth drive 33 uses an electric cylinder.
Referring to fig. 7 and 8, a plurality of fixing arms 32 are fixedly mounted on each half ring 31, the fixing arms 32 are used for mounting a material roll, the material roll is a coiled material made by winding a protective film, when the protective film is used, the material roll is directly sleeved on the fixing arms 32, along with the movement of a heat insulation pipeline in the production process, the protective film is continuously attached to a heat insulation material, and the material roll can slowly rotate under the action of a tensile force.
Further, the plurality of fixing arms 32 on the half ring 31 are divided into two groups, the curvature radius of the curve where the first group of fixing arms 32 is located is smaller than that of the curve where the second group of fixing arms 32 is located, so that the edges of the plurality of protection films are overlapped, and the heat insulation material on the heat insulation pipeline can be covered in all directions.
The embodiments of the present application are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
