Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a cleaning mechanism for a slab conveyor. When the brush roller contacts the protrusions on the surface of the slab conveyor belt, it can automatically move up and down to ensure that the distance between the brush roller and the surface of the slab conveyor belt is constant, thereby reducing the probability of excessive or insufficient cleaning force and improving the cleaning effect of the slab conveyor. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cleaning mechanism for a scale conveyor, comprising a housing, wherein the upper end of the housing is an open structure, and the interior of the housing is respectively provided with a nozzle and a rotatable brush roller, and also includes an adaptive component; Adaptive Components: These include a horizontal plate, hollow support plates, a bracket, and rollers. The horizontal plate is vertically slidably connected to the inside of the outer shell. Hollow support plates are provided on the right end of the upper surface of the horizontal plate, which is elastically limited. The brush roller is rotatably connected between the upper ends of the two hollow support plates via a rotating shaft. A water pipe is provided between the upper ends of the two hollow support plates, and nozzles are respectively set at the water outlets on the outer arc surface of the water pipe.

The outer arc surfaces of the guide posts are movably fitted with springs. The lower ends of the springs are fixedly connected to the limiting discs at the lower ends of the guide posts, providing guiding support and elastic limiting for the movement of the horizontal plate.

[0006] Furthermore, the adaptive component also includes mounting holes, which are respectively located on the left end of the upper surface of the horizontal plate. The mounting holes, which are evenly distributed laterally, cooperate with the fixing bolts at the lower end of the bracket for installation, so as to facilitate the adjustment of the left and right positions of the bracket.

[0007] Furthermore, the upper end of the outer arc surface of the guide tube is threaded with a cap, and the guide posts pass through the clearance sliding holes on the upper surface of the cap to facilitate the replacement of the spring.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This embodiment provides a technical solution: a cleaning mechanism for a slat conveyor, including a housing 1, which provides space for cleaning setup. The upper surface of the housing 1 has connection holes at both the front and rear ends for connecting the housing 1 to the slat conveyor. The upper end of the housing 1 has an open structure, which facilitates the slat conveyor belt to pass through the opening at the upper end of the housing 1 from left to right during movement. The interior of the housing 1 is provided with a nozzle 3 and a rotatable brush roller 2. High-pressure water is sprayed from the nozzle 3 to rinse the surface of the slat conveyor belt. The surface of the slat conveyor belt is cleaned by the counterclockwise rotation of the brush roller 2. The mechanism also includes a control switch group 10, which is located at the left end of the housing 1. The input end of the control switch group 10 is electrically connected to an external power source to control the start and stop of the entire device. The front surface of the housing 1 is provided with a solenoid valve to control the flow of high-pressure water. The input end of the solenoid valve is electrically connected to the output end of the control switch group 10. The mechanism also includes an adaptive component 4. Adaptive component 4 includes a horizontal plate 41, hollow support plates 42, a bracket 43, and rollers 44. The horizontal plate 41 is vertically slidably connected to the inside of the outer shell 1. Hollow support plates 42 are respectively provided on the right end of the upper surface of the elastically limited horizontal plate 41. The brush roller 2 is rotatably connected between the upper ends of the two hollow support plates 42 via a rotating shaft. A water pipe is provided between the upper ends of the two hollow support plates 42. A connecting hose is provided at the front end of the water pipe. The connecting hose is connected to the water outlet of the solenoid valve on the front surface of the outer shell 1. The nozzles 3 are respectively set at the water outlet of the outer arc surface of the water pipe. A bracket 43 is provided on the left end of the upper surface of the horizontal plate 41. The upper end of the bracket 43 is rotatably connected to the roller 44 via a rotating shaft. The roller 44 is a magnetic column. The upper end of the outer arc surface of the roller 44 is at the same horizontal plane as the upper end of the outer arc surface of the brush roller 2. During the cleaning process, under the elastic force of the elastic limiting component and the magnetic attraction of the roller 44, the upper end of the outer arc surface of the roller 44 is always in contact with the surface of the apron conveyor belt. The protrusions on the surface of the apron conveyor belt exert a force on the roller 44. With the connection of the horizontal plate 41, the brush roller 2 and the roller 44 move up and down synchronously. Due to the influence that the lateral distance between the center of the roller 44 and the center of the brush roller 2 is equal to the lateral distance between two adjacent protrusions on the surface of the apron conveyor belt, when the brush roller 2 contacts the protrusions on the surface of the apron conveyor belt, the brush roller 2 will automatically move up and down to ensure that the distance between the brush roller 2 and the surface of the apron is constant, reducing the probability of excessive or insufficient cleaning force. The adaptive component 4 also includes guide posts 45, guide tubes 46 and springs 47. The guide tubes 46 are respectively set in... The bottom wall of the outer casing 1 and the interior of the guide tube 46 are vertically slidably connected with guide posts 45. The upper ends of the guide posts 45 are fixedly connected to the lower surface of the horizontal plate 41. The outer arc surface of the guide posts 45 is movably fitted with springs 47. The lower ends of the springs 47 are fixedly connected to the limiting plates at the lower ends of the guide posts 45. Under the elastic force of the springs 47, the horizontal plate 41 is provided with elastic limit. The vertical sliding of the guide posts 45 and the guide tube 46 provides guiding support for the movement of the horizontal plate 41. The adaptive component 4 also includes mounting holes 48, which are respectively set on the left end of the upper surface of the horizontal plate 41. The mounting holes 48, which are horizontally evenly distributed, are installed with the fixing bolts at the lower end of the bracket 43. The bracket 43 is adjusted according to the horizontal spacing between two adjacent protrusions on the surface of the apron conveyor belt. The fixing bolts pass through the mounting holes 48 at the corresponding positions, so that the lateral distance between the center of the roller 44 and the center of the brush roller 2 is equal to the lateral distance between two adjacent protrusions on the surface of the scale conveyor belt. The upper end of the outer arc surface of the guide tube 46 is threaded with a cover 5. The guide pins 45 pass through the clearance sliding holes on the upper surface of the cover 5. The cover 5 is rotated periodically to open the upper end of the guide tube 46, and the guide pins 45 are pulled out from the guide tube 46 to maintain or replace the spring 47 and ensure the normal operation of the spring 47. A small pulley 8 is provided at one end of the rotating shaft of the brush roller 2. A motor 6 is provided on the opposite inner side of the two hollow support plates 42. A large pulley 7 is provided at the end of the output shaft of the motor 6. The large pulley 7 and the small pulley 8 corresponding to the vertical position are connected by a belt 9.Small pulley 8, large pulley 7, and belt 9 are located inside adjacent hollow support plates 42. The input end of motor 6 is electrically connected to the output end of control switch group 10. When motor 6 is started, the output shaft of motor 6 drives large pulley 7 to rotate. Under the transmission connection of belt 9, small pulley 8 drives brush roller 2 to rotate counterclockwise. Utilizing the different diameters of small pulley 8 and large pulley 7, belt 9 is always kept taut. A water outlet pipe 11 is provided at the water outlet on the right side of the outer casing 1. Both the front and rear ends of the bottom wall of the outer casing 1 are provided with guide plates 12. The upper surface of the horizontal plate 41 has inclined surfaces at both the front and rear ends. The two inclined surfaces are symmetrical. Under the guidance of the guide plates 12 and the inclined surfaces of the horizontal plate 41, the water inside the outer casing 1 is concentrated in the middle of the bottom wall of the outer casing 1 and discharged from the water outlet pipe 11.

[0016] The working principle of the cleaning mechanism for a slab conveyor provided by this utility model is as follows: During use, the outer casing 1 is fixedly installed at the lower end of the slab conveyor. The external high-pressure water pipe is connected to the water inlet of the solenoid valve on the front surface of the outer casing 1. Based on the lateral distance between two adjacent protrusions on the surface of the slab conveyor belt, the fixing bolts of the bracket 43 are adjusted to pass through the corresponding mounting holes 48, so that the lateral distance between the center of the roller 44 and the center of the brush roller 2 is equal to the lateral distance between two adjacent protrusions on the surface of the slab conveyor belt. During movement, the slab conveyor belt passes through the clearance opening at the upper end of the outer casing 1 from left to right inside the outer casing 1. The solenoid valve on the front surface of the outer casing 1 is opened by the control switch group 10, allowing the external high-pressure water flow to be delivered through the water pipe between the two hollow support plates 42 and sprayed onto the surface of the slab conveyor belt from the nozzle 3. The high-pressure water flow is used to flush the surface of the slab conveyor belt. Simultaneously, the motor 6 is started, and the output shaft of the motor 6 drives the large pulley 7 to rotate. Under the transmission connection of belt 9, the small pulley 8 drives the brush roller 2 to rotate counterclockwise, cleaning the surface of the apron conveyor belt. During the cleaning process, under the action of the elastic force of spring 47 and the magnetic attraction of roller 44, the upper end of the outer arc surface of roller 44 is always in contact with the surface of apron conveyor belt. The protrusions on the surface of apron conveyor belt will exert a force on roller 44, overcoming the elastic force of spring 47, so that guide post 45 and guide tube 46 slide vertically relative to each other. Under the connection of horizontal plate 41, the brush roller 2 and roller 44 move up and down synchronously. Affected by the lateral distance between the center of roller 44 and the center of brush roller 2 being equal to the lateral distance between two adjacent protrusions on the surface of apron conveyor belt, when brush roller 2 contacts the protrusions on the surface of apron conveyor belt, brush roller 2 will automatically move up and down to ensure that the distance between brush roller 2 and the surface of apron conveyor belt is constant, reducing the probability of excessive or insufficient cleaning force.

[0017] It is worth noting that the motor 6 and solenoid valve disclosed in the above embodiments can be freely configured according to the actual application scenario. The motor 6 can be a servo motor of model HC-KFS, and the solenoid valve can be a solenoid valve of model YCA21-25. The control switch group 10 is equipped with switch buttons that correspond one-to-one with the motor 6 and the solenoid valve for controlling their switching operation.

[0018] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
