As shown in FIGS. 1 to 5, a heating roller assembly for a web forming machine with a cleaning mechanism comprises two heating rollers 1 which are distributed up and down and are arranged in parallel, and a cleaning mechanism which is arranged by matching with each heating roller 1, wherein the cleaning mechanism comprises a waste trough 2 arranged below the heating rollers 1, and a cleaning brush 3 arranged on the side wall of the waste trough 2, one side wall of the waste trough 2 is positioned on the side surface of the heating roller 1, a translation assembly which is the same as the axial direction of the heating roller 1 is arranged on the side wall, the cleaning brush 3 is arranged on the translation assembly, and the cleaning brush 3 can be attached to the surface of the heating roller 1 and move in the axial direction of the heating roller 1.

Preferably, the two ends of the waste trough 1 are respectively provided with an end plate 4, the section of the waste trough is in a trapezoidal structure with a wide top and a narrow bottom, and the length of the waste trough is greater than that of the heating roller 1, so that the waste recycling effect can be improved, and the waste can be prevented from falling to influence the operation environment.

In order to avoid the cleaning mechanism from hindering the heating and conveyance of the nonwoven fabric 5, the cleaning brushes 3 corresponding to the two heating rollers 1 are provided on the opposite surfaces of the two heating rollers 1.

Two warming mill 1 are upper and lower parallel distribution, then non-woven fabrics 5 then is the S-shaped and bypasses two warming mill 1, realizes the hot pressing reinforcement to its two sides, consequently two cleaning brush 3 can not set up in the homonymy of two warming mill 1, need set up in the opposite side, avoid hindering non-woven fabrics 5' S route.

In this embodiment, the nonwoven fabric 5 is passed around from the rear side of the upper heating roller 1 and then from the front side of the lower heating roller 1 to realize hot pressing of both sides thereof, and the two cleaning brushes 3 are disposed one on the front side of the upper heating roller 1 and the other on the rear side of the lower heating roller 1.

In the process of cleaning the heating roller 1, because the heating roller 1 is in the continuous rotating process, the cleaning brush 3 can clean the cylindrical curved surface of the outer surface of the heating roller 1 at the position of the cleaning brush, and in order to clean the whole cylindrical curved surface of the heating roller 1, the cleaning brush 3 needs to be moved in the axial direction, so that a translation assembly is arranged, specifically, the translation assembly comprises a mounting groove 6 which has the length direction same with the axial direction of the heating roller 1 and has an opening facing the direction of the heating roller 1, and a ball screw 7 arranged in the mounting groove 6, a slide block 9 is arranged on a ball nut 8 of the ball screw 7, and the cleaning brush 3 is arranged on the slide block 9.

Because ball screw 7 sets up in mounting groove 6, consequently ball screw 7 then is parallel arrangement with warming mill 1, and cleaning brush 3 installs on slider 9, and ball screw 7 rotates then can utilize its ball nut 8 to drive slider 9 at ball screw 7's axial displacement, realizes cleaning brush 3's removal then, reaches the effect to warming mill 1 surface cleaning.

In order to ensure that the movement of the sliding block 9 and the cleaning brush 3 is reversed and prevent deviation, the sliding block 9 is respectively provided with a roller 10 towards the upper end and the lower end of the side surface of the mounting groove 6, the top surface and the bottom surface of the mounting groove 6 are respectively provided with a sliding groove 11, and the roller 10 rolls in the sliding groove 11.

The cooperation of the roller 10 and the sliding groove 11 can play a role of guiding the sliding block 9.

Specifically, the upper end and the lower end of the sliding block 9 are respectively provided with at least two rollers 10.

To power the rotation of the ball screw 7, one end of the ball screw 7 is connected to a driving mechanism through the end plate 4 of the chute 2.

The driving mechanism can drive the ball screw 7 to rotate, and then the sliding block 9 and the cleaning brush 3 can move.

In order to realize the automatic rotation of the ball screw 7, the driving mechanism comprises a servo motor 12 and a speed reducer 13 connected with the servo motor 12, a main gear 14 is connected on the speed reducer 13, a pinion 15 is installed at the end part of the ball screw 7, and the main gear 14 is meshed with the pinion 15.

The servo motor 12 and the reducer 13 are arranged on the outer surface of the end plate 4 of the waste material tank 2, the servo motor 12 drives the main gear 14 to rotate through the reducer 13, the main gear 14 drives the pinion 15 to rotate through meshing with the pinion 15, and the pinion 15 and the ball screw 7 are arranged in a transmission mode, so that the ball screw 7 can be synchronously driven to rotate.

In addition, the servo motor 12 can be connected with a controller to realize automatic control of the rotating speed and the rotating direction of the servo motor, so that the automation degree of cleaning is improved, the moving speed and the moving direction of the cleaning brush 3 can be adjusted as required, and the cleaning effect of the heating roller 1 is guaranteed.

Preferably, the both ends of ball screw 7 are installed on the end plate 4 of waste chute 2 through the bearing respectively, and are fixed through the bearing, can ensure that ball screw 7 can rotate under servo motor 12's drive.

The surface of the cleaning brush 3 is abraded after being used for a long time, and in order to facilitate replacement, the cleaning brush 3 comprises a brush holder 16 and a brush body 17, wherein the brush holder 16 is detachably arranged on the sliding block 9.

In order to facilitate the removal of the cleaning brush 3, a bushing 18 is mounted on the side of the slider 9 facing the heating roller 1, and a shaft 19 is mounted on the side of the brush holder 16 facing the slider 9 and engaged with the bushing 18, the shaft 19 being mounted in the bushing 18 and fixed by a pin 20.
