Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

As shown in figure 1, the cooling, rolling and crushing system for the automobile fuel tank excess material comprises a feeding device 1, a rolling device 2, a conveying device 3, a fan 4, a metal detection device 5, a discharging device 6 and a crushing device 7.

The feeding device 1, which supplies the incoming material to the rolling device 2, can adopt the existing conveying feeding technology. Automobile fuel tank blow molding clout temperature is higher, need cool off it, consequently, fan 4 sets up in loading attachment 1 top and bloies loading attachment 1 to lower the temperature to supplied materials.

And the rolling device 2 is used for rolling the supplied materials. Specifically, as shown in fig. 2 to 3, the rolling device 2 includes a frame 20, a first roller 21, a second roller 22, a rotating shaft 23, a counterweight mechanism 24, two bases 25, and a limiting rod 26. Wherein, the first roller 21 is arranged at the tail end of the feeding device 1 and is rotatably connected with the frame 20, and the second roller 22 is arranged in parallel with the first roller 21 and forms a roller gap between the two rollers. Thus, the blowing molding excess material of the automobile fuel tank is input through the feeding device 1, and is rolled through a roll gap between the second roller 22 and the first roller 21 and further cooled into a sheet. Specifically, the rotating shafts of the first roller 21 and the second roller 22 are respectively provided with a cooling liquid interface (not shown in the figure), and the circulating cooling liquid is introduced and led out through the interfaces to cool the roller bodies of the first roller 21 and the second roller 22. And cooling liquid is introduced to cool the roller body, so that the supplied materials are cooled in the rolling process, and the part can adopt the prior art.

In order to adapt to incoming materials with different sizes, the roll gap needs to be designed to be adjustable. Of course, the lower roller can be designed to be floating type by those skilled in the art under the disclosure of the present invention, and the technical solution is also within the protection scope of the present application. The pivot shaft 23 is parallel to the second roller 22 and is rotatably connected to the frame 20, and the pivot shaft 23 is rotatably connected to the rotating shaft of the second roller 22. Therefore, when the size of the supplied materials is large, the second roller 22 can be jacked up, and the second roller 22 rotates around the pivot shaft 23, so that the self-adaptive adjustment of the roller gap is realized.

In actual use, the hardness of the blow molding excess material of the automobile oil tank is greatly influenced by temperature as an incoming material, and the hardness of the incoming material is greatly different due to different temperatures. In order to roll the harder incoming material, the second roller 22 is heavier and once the second roller 22 is sized, the harder incoming material may not lift the second roller 22. Therefore, the present invention provides a counterweight mechanism 24, wherein the counterweight mechanism 24 is rotatably connected to the pivot shaft 23 and is fixed relative to the rotating shaft of the second roller 22, and the second roller 22 and the counterweight mechanism 24 are respectively disposed on two sides of the pivot shaft 23. Therefore, the counterweight mechanism 24 and the second roller 22 form a seesaw-like structure, and the material with different hardness can be accommodated by adjusting the position of the counterweight mechanism 24. In a specific implementation manner, the counterweight mechanism 24 may be fixed to the base 25 of the second roller 22 by a connecting rod.

In order to prevent the two rollers from colliding with each other, the rolling device 2 further includes two bases 25 and a limiting rod 26, the two bases 25 are respectively rotatably connected with the rotating shaft of the second roller 22, the bases 25 are rotatably connected with the rotating shaft 23 and are relatively fixed with the counterweight mechanism 24, the limiting rod 26 is disposed on the frame 20, and the top of the limiting rod is opposite to the bases 25. Thus, when the two rollers move relatively, the limiting rod 26 limits the two rollers to prevent the two rollers from colliding.

Further cooling and transport is required for the rolled cooled incoming material. Specifically, as shown in fig. 4 to 5, the device further comprises a conveying device 3, wherein the conveying device 3 comprises a conveying belt 31 which is obliquely arranged, and one lower end of the conveying belt 31 is arranged below the first roller 21 and the second roller 22. In this manner, the incoming material passing through the nip between the first and

second rollers

21 and 22 is directly dropped onto the conveyor belt 31 for conveyance. In the conveying process, the conveying device 3 further comprises a protective cover 32 and a plurality of fans 4, wherein the protective cover 32 is arranged on two side surfaces of the conveying belt 31, and the plurality of fans 4 are arranged at the top and/or the bottom of the conveying belt 31 and directly blow air to the conveying belt 31. The protective cover 32 has the functions of isolating operators and improving safety, and can also have the function of collecting wind, so that the wind blown out by the fan 4 flows along the direction of the conveyor belt 31 to continuously cool incoming materials on the conveyor belt 31.

In general, the supercooled supplied material is supplied directly to the crusher 7 and crushed by the crusher 7, and the crusher 7 may be an existing crusher.

However, in practice, it has been found that the blow-moulding residues of the fuel tanks of the motor vehicles are easily contaminated with metal components which, once they enter the breaker device 7, cause considerable damage to the breaker device 7. Therefore, incoming materials containing metal components need to be monitored and discharged. Therefore, as shown in fig. 4 to 5, the present invention further includes a metal detection device 5 and a discharge device 6, two ends of the discharge device 6 are respectively connected to the higher end of the conveyor belt 31 and the inlet of the crushing device 7, the metal detection device 5 detects metal components of incoming materials passing through the discharge device 6, and when metal components are detected, the discharge device 6 is controlled to discharge the incoming materials; when no metal component is detected, the discharge device 6 is controlled to deliver the portion of the incoming material to the crushing device 7 for crushing. Specifically, the metal detection device 5 may adopt an existing metal detector.

As a mechanical part design of automatic discharging of the discharging device 6, the discharging device 6 comprises a fixed frame 60, a second conveyor belt 61 and a cylinder 62, one end of the second conveyor belt 61 is in butt joint with the discharging end of the conveyor belt 31, the other end of the second conveyor belt is in butt joint with the crushing device 7, the metal detection device 5 is arranged above the second conveyor belt 61, one side, close to the crushing device 7, of the second conveyor belt 61 is hinged with the fixed frame 60, one side, close to the conveyor belt 31, of the second conveyor belt is hinged with the cylinder 62, and the cylinder 62 is hinged with the. In this way, when the metal detecting device 5 detects that there is a metal component, the cylinder 62 pulls the second conveyor belt 61 to rotate around the fixing frame 60 to an inclined state, and the incoming material on the second conveyor belt 61 automatically slides down and is discharged under the action of gravity.
