Background

With the development of road traffic, the traffic sign boards have more and more forms and specifications. Such as active light signs, passive light signs, single-sided sign signs, double-sided sign signs. However, no matter what kind of traffic sign, one or two layers of reflective films are firmly adhered on the indication surface of the traffic sign for traffic indication.

In the current practical work, when the reflective film is stuck incorrectly in the manufacturing stage of the traffic sign, the reflective film needs to be removed from the sign and then is pasted again. Or when the indication information of the traffic sign board changes (such as the change of place name or the change of road network), the original reflective film on the traffic sign board needs to be removed timely and quickly, and a new reflective film needs to be attached again. However, it is known that these reflective films are often adhered to the signboard body by an extremely adhesive, such as a common 3M reflective film, in order to ensure the integrity, stability and traffic safety of the traffic signboard installed outdoors. This makes the following technical problems when removing the reflective film:

firstly, current degree of automation is low, all is the manpower to clear away the reflective membrane, and reflective membrane viscidity is extremely strong, and this makes and clears away work very difficult, and not only the human consumption is big, and labor efficiency is low moreover to often remove the membrane, remove to glue unclean, influence the secondary and paste.

Secondly, the manpower is clear away the mode that the reflective membrane often appears violently clear away, leads to damaging the traffic sign body, and the maintenance cost is high.

Thirdly, because the traffic sign boards are various in form, specification and size and overall thickness, no tool with strong adaptability is used for clearing.

Fourthly, the reflective membrane, the rubber scraps and the like which are torn off by manpower cannot be collected and disposed in time, and the membrane scraps and the rubber scraps are everywhere, which easily causes pollution in factories and influences the environment.

Fifthly, a new film removing mode is developed at present, and high-pressure water is sprayed towards the traffic sign board to remove the reflective film on the traffic sign board. However, no special operation equipment is provided, and if the traffic sign board is directly placed on the ground for high-pressure washing, impurities such as sewage, membrane scraps, rubber scraps and the like are all contained everywhere, so that the pollution in a factory is easily caused, and the environment is influenced. After the label is washed, the label needs to wait too long drying time for the subsequent film pasting process, which greatly reduces the working efficiency. If the sign board is not dry enough due to urgent investment in subsequent procedures, the film pasting process is greatly influenced, the phenomena of film foaming and the like are caused, the reworking is serious, and the maintenance cost is greatly increased.

The film removing system for the traffic sign board disclosed by the invention has the advantages that through repeated tests and argumentations, the film removing (glue removing) is clean in a high-pressure spraying mode, meanwhile, the air drying mechanism 3 is integrated, so that the traffic sign board can be air-dried as soon as possible, and further, the next-stage film sticking process can be quickly carried out, the working efficiency is greatly improved, the smoothness and the attractiveness of subsequent film sticking of the panel are greatly improved, and the product quality is improved.

As shown in fig. 1 to 7, further, in the preferred embodiment, the cleaning mechanism 2 includes a mounting frame 21 and a punching pipe assembly 22 disposed on the mounting frame 21, a tail end of the punching pipe assembly 22 is used for communicating with a high-pressure water source, and a spraying end is disposed toward the traffic sign, a translation assembly 23 for driving the punching pipe assembly 22 to translate back and forth left and right is disposed on the mounting frame 21, and the translation assembly 23 controls a translation range of the punching pipe assembly 22 for different sizes of traffic signs during operation, so that the punching pipe assembly 22 can adapt to different sizes of traffic signs. For example, when the width of the traffic sign board is one meter, the translation assembly 23 controls the ram tube assembly 22 to perform left-right reciprocating translation cleaning within a translation range of one meter (or slightly more than one meter). When the width of the next batch of traffic signs is two meters, the translation assembly 23 controls the punch pipe assembly 22 to perform left-right reciprocating translation cleaning within a translation range of two meters (or slightly more than two meters). In any case, the lateral range of the traffic sign can be laterally covered. Through the special scientific design, the method has the following technical advantages:

Firstly, the membrane removing system for the traffic sign board controls the punching pipe assembly 22 to reciprocate and translate for cleaning by arranging the translation assembly 23, so that the punching pipe assembly 22 is not required to be arranged too wide, and a large amount of high-pressure objects (such as high-pressure water) with wide width are not required to be sprayed at the same time, so that the device is energy-saving and environment-friendly, and the manufacturing cost and the operation cost are greatly saved. Secondly, the film removing system for the traffic sign board of the invention enables the punching pipe component 22 to adapt to various traffic sign boards with different widths by arranging the translation component 23, and has good cleaning effect and strong product adaptability.

Further, as shown in fig. 5 to 7, in a preferred embodiment, the translation assembly 23 includes a transverse mounting plate 231, the mounting plate 231 is provided with a translation slide rail 232, a first motor 233 and an endless drive belt assembly 234, the ram tube assembly 22 is slidably mounted on the translation slide rail 232 and connected to the endless drive belt assembly 234, and the first motor 233 is configured to drive the endless drive belt assembly 234 to move forward and backward to drive the ram tube assembly 22 to reciprocate left and right along the translation slide rail 232. In this embodiment, two parallel translation slide rails 232 are provided, so that the limiting installation of the ram tube assembly 22 is stable, and the stability is high during high-pressure flushing. The endless drive belt assembly 234 includes two drive wheels and an endless drive belt wound around the drive wheels, the first motor 233 is used to drive one of the drive wheels in forward and reverse directions to cause forward and reverse transmission of the endless drive belt, and the ram tube assembly 22 is fixedly connected to the endless drive belt. The structure is simple, easy to manufacture and maintain, and stable in operation.

As shown in fig. 5 to 7, further, in the preferred embodiment, the left and right ends of the mounting plate 231 are rotatably mounted on the mounting frame 21 through a first rotating shaft 2311, the left and right ends of the mounting plate 231 are provided with an adjusting screw 2312 protruding outwards below the first rotating shaft 2311, the left and right ends of the mounting frame 21 close to the mounting plate 231 are fixed with an adjusting plate 211, the adjusting plate 211 is provided with an adjusting long hole 2111, and the adjusting screw 2312 passes through the adjusting long hole 2111 and is fastened through a nut for adjusting the high-pressure injection angle of the ram pipe assembly 22 by adjusting the inclination angle of the mounting plate 231. Through the above arrangement, the high-pressure spraying angle of the punching pipe assembly 22 can be adjusted, and different operation requirements can be met. For example, some signboards are of a single-sided structure and are thin, in order to prevent the high-pressure object from deforming the surface of the signboard, namely, the surface of the signboard is concave, the high-pressure injection angle of the punching pipe assembly 22 can be adjusted, the injection path is longer, and the high-pressure injection is relatively softer on the premise of ensuring the cleaning effect. In some signboards, for example, where the film is extremely tacky and the sign face is thick, the punch tube assembly 22 can be forcibly removed by directing a short downward distance of high pressure jet. Through above special scientific design for this device adaptability is stronger, can adapt to the denoter of different thickness, the operation demand of cleaing away respectively of different gluey nature reflective membrane.

As shown in fig. 5 to 7, further, in a preferred embodiment, the ram tube assembly 22 includes at least two medium pressure guns 221 and two high pressure guns 222 with different ram pressures, the nozzle angles of the medium pressure guns 221 and the high pressure guns 222 are adjustable, and the medium pressure guns 221 and the high pressure guns 222 can be independently opened to adapt to the injection requirements of different traffic signs or can be simultaneously opened to make the medium pressure guns 221 perform secondary injection compensation on the high pressure guns 222 by adjusting the nozzle angles. In addition to the above-described adaptation of the high pressure spray angle of the spray ram tube assembly 22 to the spray requirements of different traffic signs, the present invention is further inventive in that different pressure ram barrel designs are provided. For example, some signboards are single-sided and thin, and in order to prevent the high-voltage object from deforming the surface of the signboard, the surface of the signboard is punched to be concave, the medium-voltage gun 221 can be used for medium-voltage spraying, and the high-voltage spraying is relatively softer on the premise of ensuring the cleaning effect. In some signboards, for example, which have a very strong film adhesion and a thick signboard face, the high-pressure gun 222 alone can be used to perform high-pressure spraying and strong cleaning. Even if the medium pressure gun 221 and the high pressure gun 222 can be simultaneously turned on, the injection force is larger. More importantly, the angles of the nozzles of the medium-pressure gun 221 and the high-pressure gun 222 are adjustable, the medium-pressure gun 221 can be used for performing secondary injection compensation on the high-pressure gun 222, for example, the films of some signboards have extremely strong viscosity, the high-pressure gun 222 can be used for removing and crushing the originally adhered films and colloids, and then the medium-pressure gun 221 is used for further flushing the crushed film scraps and colloid scraps out of the panel, so that secondary residual adhesion is not formed on the panel, and an excellent removing effect is effectively ensured. That is, the medium pressure gun 221 and the high pressure gun 222 are mutually matched, the high pressure gun 222 plays a role of powerful stripping, and the medium pressure gun 221 plays a role of compensation cleaning.

As shown in fig. 1 to 4, further, in the preferred embodiment, the cleaning mechanism 2 further includes a film collecting cover 24 covering the installation frame 21 for collecting the removed foreign matters during operation, the bottom of the film collecting cover 24 is provided with an opening for spraying the punching pipe assembly 22 downwards, and the edge of the bottom opening of the film collecting cover 24 is provided with a ring of elastic scraping portions 241 for pressing on the traffic sign during operation to scrape the removed foreign matters. In this embodiment, the film-collecting cover 24 is made of a transparent material. When the high-pressure water is sprayed to remove the operation, the film collecting cover 24 is arranged, so that high-pressure water, flushed film scraps and glue scraps can be blocked at the film collecting cover 24, and the problems of operation environment damage and pollution can be avoided. So that water, membrane scraps and adhesive scraps can only fall from the bottom opening of the membrane collecting cover 24. At this time, by providing the elastic scraping portion 241, the falling water, film scraps and glue scraps can be scraped from the traffic sign (and the top of the adjacent bearing platform 1). Secondly, the signboards are different in thickness, even some backs are provided with slide rail mounting rods, and the elastic arrangement of the scraping and sweeping parts 241 enables the signboards with different thicknesses to extrude the scraping and sweeping parts 241 and enter the bottom of the film collecting cover 24 for cleaning, and non-extruded areas can keep a good sealing effect, so that water, film scraps and glue scraps are prevented from rushing out of the film collecting cover 24.

Due to the high pressure washing, the traffic sign may shift during operation, which may result in inaccurate and incomplete cleaning. Therefore, the invention further designs the limiting pushing mechanism 5, and during cleaning operation, the limiting pushing mechanism 5 is turned downwards and pressed on the traffic sign board, so that the traffic sign board cannot be displaced. Meanwhile, the limiting pushing mechanism 5 is integrally installed at the bottom of the installation rack 21, so that the limiting pushing mechanism can move along with the installation rack 21. That is, the pressing area of the limiting pushing mechanism 5 is always arranged close to the installation rack 21 (the punching pipe assembly 22), that is, the area with the largest impact force, so that the pressing and limiting effects are good. More importantly, the limiting pushing mechanism 5 integrates two functions of limiting and pushing: when the cleaning operation is completed and the mounting frame 21 moves back to the rear of the tail end of the traffic signboard, at this time, there is no traffic signboard below the limiting pushing mechanism 5, and then the limiting pushing mechanism 5 is turned over again and moves to the side wall of the tail end of the traffic signboard, that is, the limiting pushing mechanism 5 moves to the side wall of the traffic signboard from the upper part of the top surface of the original traffic signboard. Then the cleaning mechanism 2 moves back from back to front, and the limiting pushing mechanism 5 positioned at the side wall of the traffic sign board pushes the side wall of the traffic sign board and gradually pushes the traffic sign board under the driving of the cleaning mechanism 2 to dry towards the air drying mechanism 3. When the traffic sign is completely pushed out of the bearing platform 1, the cleaning mechanism 2 is just translated to the front end of the bearing platform 1, so that the next traffic sign to be washed and removed of glue can be just waited for, and then the traffic sign is moved forwards and backwards again to gradually remove the newly transported traffic sign. Therefore, the normal reset movement of the cleaning mechanism 2 is utilized, the traffic sign board can be just pushed to be air-dried after being cleaned through the limiting pushing mechanism 5, and two functions are realized through one action.
