The automatic roller cleaning device provided by the invention has a structure shown in figure 1 and comprises a device body 1 and a limiting part 3. A be equipped with multiunit roller assembly in the roll table for carrying the product, roller assembly includes running roller 4 and roller shaft 5, and each cover of both ends of every roller shaft 5 is equipped with a running roller 4 usually, and roller shaft 5 drives running roller 4 and rotates, and then realizes the transportation of product. The device body 1 is approximately rectangular, and the distance between two opposite side edges is larger than or equal to the distance between the end edges of the two rollers 4 which are far away from each other. The lower end face of the device body 1 is provided with a cleaning cloth 2, and the width of the cleaning cloth 2 is larger than or equal to the height of the roller 4. When the device body 1 is placed on the roller way, the cleaning cloth 2 on the lower end face of the roller wheel 4 can be attached to the roller wheel 4. When the roller 4 rotates, the device body 1 moves synchronously under the action of friction force. Spacing portion 3 is located the lower terminal surface of device body 1 to downwardly extending can offset with the running roller 5 of running roller 4, and spacing portion 3 can the removal of restriction device body 1, makes device body 1 and running roller 4 produce relative motion, and the rag 2 on the device body 1 takes place the spot of running roller 4 periphery to wipe away with running roller 4 in-process of relative motion. The limiting portion 3 may be a limiting rod fixedly connected to the device body 1 by welding or the like.

Alternatively, as shown in fig. 2, the apparatus body 1 includes a pressing block 11 and a cross beam 12. Specifically, when the automatic cleaning device for the roller of the roller way works, the pressing block 11 is vertical to the axial direction of the roller 4. The length of the pressing block 11 is usually 2 times larger than the distance between two adjacent roller shafts 5, and the pressing block 11 is always supported by at least two rollers 4, so that the pressing block 11 is prevented from sliding off from a gap between the roller shafts 5. Generally, to improve the cleaning efficiency, the length of the compact 11 can be increased as much as possible, as shown in fig. 4, and in one embodiment of the present application, the length of the compact 11 is greater than 5 times the distance between two adjacent roller shafts 5. Of course, the user may set the length of the pressing block 11 as needed, and is not limited herein. The number of the pressing blocks 11 is equal to the number of the rollers 4 on each roller shaft 5, and generally, the device body 1 comprises two pressing blocks 11 which are arranged in parallel. The two pressing blocks 11 are fixed by a cross beam 12. The device body 1 moves on the roller way as a whole to realize the cleaning of the roller 4.

Optionally, when the device body 1 and the roller 4 move relatively, the cleaning cloth 2 bears a large friction force, and the end of the pressing block 11 is further provided with a fixing mechanism 13 to prevent the cleaning cloth 2 from loosening. As shown in fig. 2, the fixing mechanism 13 extends outward from one end of the pressing piece 11. The cleaning cloth 2 is bagged, is sleeved on the periphery of the fixing mechanism 13 and then overturns towards the lower part of the pressing block 11. The cleaning cloth 2 and the fixing mechanism 13 can be further reinforced by a fixing clip and the like.

In this embodiment, modes such as manual transport or hoist and mount are placed on the roll table to roll table running roller self-cleaning device. And then, the roller 4 on the roller way rotates to drive the automatic cleaning device of the roller way roller to move together, and when the limiting part 3 abuts against the roller shaft 5, the automatic cleaning device of the roller way roller is blocked from moving, so that the automatic cleaning device of the roller way roller and the roller 4 move relatively. At the moment, the cleaning cloth 2 rubs with the outer surface of the roller 4 to clean the stains on the outer surface of the roller 4, so that the roller of the roller way is automatically cleaned.

Alternatively, the roller table for conveying the products is usually long, and the length of the device body 1 does not exceed a certain limit for the convenience of carrying. In order to clean all the rollers 4, the automatic roller cleaning device needs to move along the conveying direction of the roller while cleaning. Thus, in one embodiment of the present application, the stop portion 3 employs an intermittent blocking assembly, which includes a blocking rod 36 and a pushing mechanism, as shown in fig. 3. Wherein, the upper end of the blocking rod 36 is hinged with the device body 1, the lower end is suspended, and the pushing mechanism pushes the blocking rod 36 along the conveying direction of the roller way.

Specifically, the roller way roller automatic cleaning device moves along the conveying direction of the roller way in the working process. When the blocking rod 36 abuts against the roller shaft 5, the blocking rod 36 will rotate around the hinge shaft at the upper end thereof, and the abutting mechanism abuts against the blocking rod 36 along the conveying direction of the roller way, so as to slow down the rotation speed of the blocking rod 36. Thereby slowing down the moving speed of the device body 1 and generating relative displacement between the device body 1 and the roller 4. The roller automatic cleaning device continues to move, and certainly, the user can also set a torsion spring between the gear lever 36 and the device body 1 according to needs, and the rotation speed of the gear lever 36 is reduced through the torsion spring, which is not limited herein.

Alternatively, as shown in fig. 3, the pushing mechanism includes a cylinder 32 and a support rod 35. Wherein, the cylinder 32 is provided with a through hole penetrating along the thickness direction towards one end of the stop lever 36, and one end of the support rod 35 is larger in diameter and is arranged in the cylinder 32 and in clearance fit with the cylinder 32. The other end passes through the through hole and is suspended outside the cylinder barrel 32. The foremost end of the support rod 35 abuts against the stopper rod 36. The cylinder 32 is provided with a support spring 33 of the support rod 35, and the support spring 33 is abutted against one end of the support rod 35 in the cylinder 32 to provide damping for the movement of the support rod 35 and slow down the rotation speed of the stop lever 36. Of course, the user may also use an air cylinder, an oil cylinder, etc. as the pushing mechanism according to the requirement, and directly push against the support rod 35 through the piston.

Alternatively, the cylinder 32 may be connected to the beam 12 through a fixing block 31, and the fixing block 31 may be connected to the beam 12 through welding or bolting. The front end of the cylinder barrel 32 is further provided with a guide part 34, the guide part 34 is provided with a guide hole which corresponds to the position of the through hole and is parallel to the conveying direction of the roller way, and the support rod 35 penetrates through the guide hole. When the supporting rod 35 abuts against the pushing rod 36, the guide portion 34 can prevent the supporting rod 35 from deflecting to affect the normal movement of the roller automatic cleaning device.

Further, the cylinder 32 is further connected with a pneumatic support mechanism, the pneumatic support mechanism inflates air into the cylinder 32, and the rotation speed of the gear lever 36 is reduced through the pneumatic support rod 35. Specifically, the cylinder 32 is connected with an air inlet pipe and an air outlet pipe, the air inlet pipe is provided with a one-way valve 37, and the air outlet pipe is provided with a throttle valve 38. The gas enters the cylinder 32 through the gas inlet pipe and flows out through the gas outlet pipe. The throttle valve 38 in the outlet pipe can slow down the gas outflow speed, so that a certain air pressure is maintained in the cylinder 32 to support the support rod 35. In addition, a flow valve can be arranged in the gas outlet pipe, and an operator controls the gas flow through the flow valve so as to control the gas pressure in the cylinder barrel 32. When the air pressure in the cylinder 32 is larger, the supporting force applied to the supporting rod 35 is larger, and the pushing force of the supporting rod 35 against the stopper 36 is also larger. At the moment, the moving speed of the automatic roller way roller cleaning device is lower, and the cleaning effect is further improved. Otherwise, the cleaning efficiency of the automatic cleaning device for the roller way roller is higher. The user can adjust the opening degree of the flow valve according to the requirement, and the cleaning effect is improved or the cleaning efficiency is improved. Of course, the user can also adopt a hydraulic mode to adjust the moving speed of the roller automatic cleaning device according to the needs, and the principle of the device is similar to that of air pressure adjustment, and is not described again here.

In this embodiment, the limiting portion 3 of the automatic roller cleaning device adopts an intermittent blocking component, and the intermittent blocking component enables the device body 1 and the roller 4 to move relatively by slowing down the moving speed of the device body 1, so as to clean stains on the roller 4. And after the stop lever 36 strides over one roller shaft 5, the roller automatic cleaning device continues to move forward to clean the rollers 4 on the next roller shaft 5, thereby realizing the automatic cleaning of all the rollers 4 on the roller. In addition, the intermittent blocking assembly controls the moving speed of the automatic roller cleaning device through air pressure or hydraulic pressure, so that an operator can adjust the cleaning effect and the cleaning efficiency as required.
