[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an electronic belt scale roller maintenance device, which includes a cleaning trough body, a nozzle, a cleaning rod 21, and a water receiving box, wherein the front end side plate 11 and the rear end side plate of the cleaning trough body are both provided with an arc-shaped open groove 12 for matching with the roller 41; the cleaning rod is arranged in the cleaning trough body, the cleaning rod 21 is parallel to the roller 41, and the two ends of the cleaning rod are rotatably connected to the front end side plate 11 and the rear end side plate respectively; a plurality of bristles for contacting the outer circumferential surface of the roller are evenly distributed on the outer circumferential surface of the cleaning rod; the nozzle is arranged on the cleaning trough body and faces the roller, and the nozzle is connected to both the water supply pipeline and the air supply pipeline; a driving mechanism for driving the cleaning rod 21 to rotate is arranged outside the cleaning trough body, a drain pipe is arranged at the lower part of the front end side plate 11, the water receiving box is arranged directly below the roller, and the lower end of the drain pipe is connected to the water receiving box.

[0024] The electronic belt scale roller maintenance device provided by the embodiment of the present invention, when in use, makes the cleaning trough body close to the bottom or one side of the roller, and then supplies cleaning water and compressed air to the nozzle through the water supply pipeline and the air supply pipeline respectively, so that the nozzle sprays atomized water onto the roller to clean, rinse and moisten the dirt on the outer circumferential surface of the roller to facilitate the dirt to fall off, and then drives the cleaning rod to rotate through the driving mechanism, and utilizes the friction force when the bristles contact the roller to make the roller rotate with the cleaning rod, and utilizes the cleaning rod 21 to remove the wetted dirt on the outer circumferential surface of the roller 41 through the bristles, thereby realizing the maintenance of the roller and making the roller cleaner; at the same time, the sewage flowing down from the outer circumferential surface of the roller is discharged into the water receiving box through the drain pipe, thereby better avoiding pollution to the environment of the production site and facilitating the centralized treatment of sewage.

[0025] Furthermore, the driving mechanism is a pneumatic motor, so that the cleaning rod is driven to rotate by the pneumatic motor.

[0026] Specifically, a control valve for switching the air intake and exhaust direction of the air motor is provided on the air supply circuit of the air motor, so that the air intake and exhaust direction of the air motor can be switched through the control valve, so that the air motor can be rotated forward and reversely, so that the cleaning rod can be rotated forward and reversely, and the roller can be cleaner after maintenance. It can be understood that the structure of the cleaning rod is the same as the structure of the cleaning rod with bristles in the prior art, which will not be repeated here; the forward and reverse rotation of the cleaning rod can be clockwise and counterclockwise respectively; the switching principle of the air intake and exhaust direction of the air motor is the same as the switching principle of the air motor that can rotate forward and reverse in the prior art, which will not be repeated here; the driving mechanism can also be a driving motor that can rotate forward and reverse. It can be preferred that the air motor and the nozzle share an air source to effectively reduce the number of parts and components and reduce the manufacturing cost of the electronic belt scale roller maintenance device.

[0027] Furthermore, a sealing strip is provided on the wall surface of the arc-shaped opening groove 12, so as to better prevent the sewage after cleaning from leaking out of the cleaning groove body. The cleaning groove body can be made of thicker stainless steel; the water receiving box can also be made of stainless steel; the nozzle can be set in the fixing hole 13 of the front side plate 11, and the drain pipe is set in the drain hole 14.

[0028] Preferably, the nozzle is arranged on the upper part of the front side plate 11 and close to the roller, so as to achieve a better cleaning effect. It is understandable that a manual stainless steel water valve can be provided on the water supply pipeline to control the on-off of the water supply pipeline, and the water outlet of the manual stainless steel water valve can be provided with a first quick connector, and the nozzle can be connected to the first quick connector provided on the water supply pipeline through a water supply hose; an air valve can be provided on the air supply pipeline to control the on-off of the air supply pipeline, and the air outlet of the air valve can be provided with a second quick connector, and the nozzle can be connected to the second quick connector provided on the air supply pipeline through a compressed air hose.

[0029] Specifically, the drain pipe is arranged close to the roller 41, so that the sewage in the cleaning tank can be smoothly discharged into the water receiving box through the drain pipe. It can be understood that the water receiving box is used to collect the sewage discharged from the drain pipe and prevent the sewage from dripping on the belt; the length of the water receiving box is greater than the length of the cleaning tank; when the length of the roller is small, the length of the water receiving box can be consistent with the length of the roller 41.

[0030] Furthermore, the front side plate 11 and the rear side plate are both provided with mounting holes 15, and the two mounting holes 15 are coaxially arranged; a bearing seat is arranged in the mounting hole 15, a bearing is arranged in the bearing seat, and the mounting shaft 22 of the cleaning rod 21 is arranged in the bearing. With this solution, the cleaning rod can be conveniently connected to the front side plate 11 and the rear side plate by rotation by only having the mounting shafts at both ends of the cleaning rod respectively arranged in the two bearings. It can be preferred that the mounting hole 15 is arranged at the lower middle part of the front side plate and the rear side plate.

[0031] Specifically, an operating handle 31 is provided on the outer wall of the upper side plate 16 of the cleaning tank body, and the operating handle is parallel to the roller, so that the operator can reciprocate the cleaning tank body in the axial direction of the roller through the operating handle, so that even the roller with a longer length can be relatively clean after maintenance. It can be preferred that the operating handle is a round rod. It can be understood that during the maintenance process, the roller is cleaned as much as possible in the direction of rotation of the roller from the nozzle to the exhaust pipe, and the cleaning time in the opposite direction is reduced on the basis of ensuring the cleaning effect of the roller, so as to effectively avoid excessive overflow of atomized water sprayed from the nozzle; the air supply pipeline and water supply pipeline led by the nozzle can be set in the operating handle, and a part of the air supply circuit led by the pneumatic motor can also be set in the operating handle, so that the layout of each pipeline can be more compact and orderly.

[0032] The above are only preferred embodiments of the present invention. It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
