[0024] In order to make the purpose, technical scheme and advantages of the utility model embodiment more clear, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in any way without conflict.

[0025] Please refer to Figure 1 and Figure 2 A self-cleaning elevator back plate is arranged on the back of the lifting belt of the elevator 30, which comprises a roller shutter 10 and a roller shaft 11. The roller shaft 11 is hingedly arranged on the two side plates of the elevator 30 at both ends, and the roller shutter 10 is fixedly arranged on the roller shaft 11 at one end. The roller shaft 11 can be driven to rotate forward and reverse, so that the roller shutter 10 is wound on the roller shaft 11 or the roller shutter 10 is unfolded and laid under the lifting belt. The cleaning assembly 20 is arranged between the roller shutter 10 and the lifting belt, and the cleaning assembly 20 acts on the roller shutter 10 to clean the roller shutter 10 during movement.

[0026] The roller shaft 11 and the roller shutter 10 are both arranged under the lifting belt. The roller shaft 11 can rotate around its own central axis relative to the lifting belt. The roller shutter 10 is fixed to the roller shaft 11 at one end. When the roller shaft 11 rotates, the roller shutter 10 rotates with the roller shaft 11 and gradually winds on the roller shaft 11, and the roller shutter 10 is wound. When the roller shaft 11 reversely rotates, the roller shutter 10 rotates with the roller shaft 11 and gradually unfolds. The unfolded roller shutter 10 under the lifting belt can be used as a back plate.

[0027] The guide rails 12 are arranged on the two side plates of the lifting belt, and the guide rails 12 are arranged on the end faces of the side plates facing the other side plates. The roller shutter 10 is arranged on the guide rails 12 on both sides, and the guide rails 12 provide support on both sides of the roller shutter 10, so that the roller shutter 10 in the form of a rectangle after unfolding can maintain the state of unfolding, avoiding the unfolded roller shutter 10 from collapsing and deforming.

[0028] Further, in order to make the roller shutter 10 move along the guide rail 12 smoothly and be laid flat under the lifting belt, the roller shutter 10 is further provided with counterweights (not shown in the figure), and the two counterweights are arranged close to the two sides of the roller shutter 10 respectively, so that the side edges of the roller shutter 10 and the counterweights are all located on the guide rail 12. When the roller 11 rotates to expand the roller shutter 10, the counterweights slide downward along the guide rail 12 under the action of their own gravity, thereby driving the end of the roller shutter 10 to move, so that the roller shutter 10 is expanded and laid flat under the lifting belt; when the roller 11 rotates to wind up the roller shutter 10, under the action of the gravity of the counterweights, the roller shutter 10 always keeps an expanded and laid flat state during the movement along the guide rail 12, so that the roller shutter 10 is wound up smoothly.

[0029] Preferably, the guide rail 12 is provided with a guide groove 121, which is arranged on the side end face of the guide rail 12 facing the other guide rail 12. The guide groove 121 is a straight groove extending along the guide rail 12, and the side edge of the roller shutter 10 is arranged in the guide groove 121. The inner wall of the guide groove 121 forms a limit above the roller shutter 10, which can prevent the roller shutter 10 from moving upward and separating from the guide rail 12 under the action of external force.

[0030] Preferably, a plurality of rollers 13 are arranged in the guide groove 121, and the rollers 13 can rotate around their own axes. The rollers 13 are arranged in the length direction of the guide groove 121 at intervals, and the side edge of the roller shutter 10 is arranged on the rollers 13. When the roller shutter 10 moves in the guide groove 121, the rollers 13 and the roller shutter 10 are in rolling friction, which can reduce the friction received by the roller shutter 10 during the movement and reduce the wear of the roller shutter 10.

[0031] In the embodiment, the roller 11 is connected to the output shaft of the motor, and the roller 11 is driven to rotate by the motor. The motor is connected to the PLC, and the PLC controls the forward and reverse rotation of the motor to realize the laying and winding of the roller shutter 10.

[0032] Preferably, in the length direction of the guide rail 12, the guide rail 12 is provided with sensors at both ends, which are photoelectric sensors in the embodiment, and are used to detect whether the roller shutter 10 has moved to the position. The sensors are electrically connected to the PLC, and the PLC controls the start and stop of the motor according to the position information of the roller shutter 10 fed back by the sensors. Specifically, when winding the roller shutter 10, the motor rotates, and after the end of the roller shutter 10 moves to the upper end of the guide rail 12 is detected by the upper sensor, the PLC controls the motor to stop, and the winding of the roller shutter 10 is completed; when laying the roller shutter 10, the motor reverses, and after the end of the roller shutter 10 moves to the lower end of the guide rail 12 is detected by the lower sensor, the PLC controls the motor to stop, and the laying of the roller shutter 10 is completed.

[0033] The roller shutter 10 comprises a plurality of shutter leaves connected end to end, and adjacent shutter leaves are hingedly connected. When being rolled up, the shutter leaves are rotated and wound on the roller shaft 11. Specifically, in the embodiment, the roller shutter 10 is an aluminum alloy polyurethane composite roller shutter 10, which is light in weight and has good anti-elastic deformation ability during laying and is not easy to deform.

[0034] Further, the roller shutter 10 is provided with a wear-resistant layer (not shown in the figure) on the side facing the lifting belt. The wear-resistant layer is adhered to the roller shutter 10 to prevent materials from falling off the lifting belt during transportation and falling into the gaps between the shutter leaves, which causes the rotation of the shutter leaves to be limited and the roller shutter 10 to be unable to be rolled up on the roller shaft 11. Specifically, the wear-resistant layer is a high-silicon fiber cloth, which has the characteristics of wear resistance and tear resistance, can avoid mutual friction between the shutter leaves during rolling up, and prolongs the service life of the roller shutter 10.

[0035] The cleaning assembly 20 is arranged between the lifting belt and the roller shutter 10 and comprises a brush 21 and a spray head 22. The bristles of the brush 21 are in contact with the roller shutter 10. When the roller shutter 10 moves relative to the brush 21, the brush 21 sweeps across the roller shutter 10 to achieve the purpose of cleaning. The spray head 22 is connected to a gas source and sprays the roller shutter 10. Specifically, the brush 21 is fixedly connected to the two end plates. The brush 21 and the spray head 22 are arranged in sequence along the moving direction of the roller shutter 10, and the spray head 22 is close to the roller shaft 11. When the roller shutter 10 is rolled up, the roller shutter 10 moves upward, and the brush 21 and the roller shutter 10 move relative to each other. The bristles of the brush 21 brush the roller shutter 10 to clean the dust falling on the roller shutter 10. Then, the spray head 22 blows air on the cleaned roller shutter 10 to further clean it.

[0036] Preferably, the cleaning and blowing assembly is arranged close to the roller shaft 11. During the rolling up of the roller shutter 10, the vibration generated by the movement of the roller shutter 10 along the guide rail 12 before it moves to the cleaning assembly 20 can make the dust adhered to the roller shutter 10 loose, which facilitates the cleaning of the roller shutter 10 by the brush 21.

[0037] During cleaning, the PLC drives the motor to rotate, the roller shaft 11 rotates to roll up the roller shutter 10 laid under the lifting belt, the roller shutter 10 moves upward along the guide rail 12 to the position of the cleaning assembly 20, the roller shutter 10 is in contact with the brush 21, the brush 21 brushes off the dust deposited on the roller shutter 10, and the spray head 22 sprays the cleaned roller shutter 10 to thoroughly clean the small amount of dust remaining on the roller shutter 10 until the end of the roller shutter 10 moves to the upper end of the guide rail 12. The PLC controls the motor to stop, and the cleaning and rolling up of the roller shutter 10 are completed. During use, the PLC drives the motor to reverse, the roller shaft 11 reversely rotates to make the roller shutter 10 loose from the roller shaft 11, and the roller shutter 10 moves downward along the guide rail 12 under the driving of the counterweight until the end of the roller shutter 10 moves to the lower end of the guide rail 12. The PLC controls the motor to stop, and the laying of the roller shutter 10 is completed.

[0038] It should be finally pointed out that: the above examples are only used to illustrate the technical solutions of the utility model, and not limit it.
