Detailed Description

An embodiment of the nonwoven finishing assembly of the present invention is further described with reference to fig. 1.

The non-woven fabric after-finishing device is provided with a transportation module used for conveying non-woven fabrics below the non-woven fabric after-finishing device, and meanwhile, the transportation module is connected with the after-finishing device through an external shell 101, so that the non-woven fabrics are in a relatively closed space in the transportation process. The transport module may take the form of a conveyor belt 102, laying the nonwoven fabric flat onto the conveyor belt 102 and transporting the nonwoven fabric from below the apparatus using the conveyor belt 102; the transport module may also take the form of a transport roller 103, with the cooperation of a plurality of transport rollers 103 ensuring that the nonwoven is laid flat beneath the device. Simultaneously the device is including the bucket body 11 that is used for leading powdered auxiliary agent and roller 12 to meet, bucket body 11 adopts the top opening big, and the below export is little, and the size of below export and the structure phase-match of roller 12, and preferred underground side export is the rectangle. Meanwhile, a roller shaft 12 is arranged at an outlet below the hopper body 11, a plurality of grooves 13 are uniformly distributed on the roller shaft 12, and a brush 14 is further arranged on one side of the roller shaft 12.

Example 1

A vibrating screen device 2 is arranged above the hopper body 11, and a metering module 21 is arranged on the vibrating screen device 2. The vibrating screen device 2 comprises a vibrating screen 22 and a power device, the power device adopts the design of an eccentric wheel 23, and the rotating of the eccentric wheel 23 drives the vibrating screen 22 to vibrate up and down, so that the auxiliary agent is uniformly distributed downwards. Meanwhile, the metering module 21 arranged above the vibrating screen device 2 is used for recording the mass of the auxiliary agent added into the vibrating screen 22 every time, and the control of the unit area auxiliary agent amount of the non-woven fabric can be realized by adjusting the mass of the added auxiliary agent and the transportation speed of the transportation module arranged below the after-treatment device. And the metering module 21 is connected to a PLC control panel provided outside the finisher.

Example 2

When the number of the brushes 14 is single, the rotation direction of the roller 12 is from the outlet of the bucket body 11 to the direction of the brushes 14. That is, when the brush 14 is horizontally disposed at the right side of the roller 12 and the horizontal plane at which the brush 14 is disposed passes through the axial core of the roller 12, the roller 12 rotates clockwise, and when the brush 14 is horizontally disposed at the left side of the roller 12 and the horizontal plane at which the brush 14 is disposed passes through the axial core of the roller 12, the roller 12 rotates counterclockwise. Meanwhile, a motor for providing power for the roll shaft 12 is externally connected with a PLC control panel.

Example 3

The grooves 13 are arranged in the longitudinal direction of the roll shaft 12. Meanwhile, the bottom surface of the groove 13 adopts an arc surface 131 which is concave towards the center of the roll shaft 12, and the contact part with the side wall of the groove 13 adopts a fillet 132 for transition. The grooves 13 are arranged longitudinally so that the agent is evenly spread into the interior thereof, and the brush 14 is contacted by the roller 12 to sweep the agent from the grooves 13 onto the nonwoven fabric thereunder. The design of the cambered surface 131 and the fillet 132 avoids the shortage of the assistant amount per unit area of the non-woven fabric caused by the assistant being clamped in the groove 13. Preferably, the width of the groove 13 is controlled to be 5mm to 10 mm. The depth of the groove 13 is also controlled to be 4mm to 8 mm. In addition, the roll shaft 12 and the after-finishing device are detachably connected, so that an operator can conveniently adjust the required amount of the auxiliary agent according to the type of the auxiliary agent and the non-woven fabric.

Example 4

The distance between the brush 14 and the roller 12 is adjustable.

Preferably, the end of the brush 14 on the side remote from the roller shaft 12 is connected to a servo-electric cylinder 140.

When the length of the brush 14 in the longitudinal direction of the roll shaft 12 is greater than or equal to the length of the roll shaft 12, the servo electric cylinder 140 is fixed to the frame body;

the brush 14 may be a first brush 141, the first brush 141 includes bristles 149, the bristles 149 are fixed on a bristle surface of the brush plate 148, the brush plate 148 is accommodated in a brush housing 1411, a bristle surface of the brush plate 148 is connected to an inner wall of the brush housing 1411 through an elastic element 1412, at least one vibration module 1413 is disposed on a non-bristle surface of the brush plate 148, and the bristles 149 can be moved up, down, left and right by the vibration module 1413. In the first brush 141 structure, the vibration module 1413 enables the bristles 149 to move correspondingly when the bristles 149 are in contact with the grooves 13 of the roller 12, so as to sweep the auxiliary agent in the grooves 13, and the auxiliary agent is placed and accumulated in the grooves 13, so that the auxiliary agent amount on the non-woven fabric is insufficient;

the brush 14 can also be a second brush 142 structure, the second brush 142 structure includes bristles 149, and the bristles 149 are distributed on the circular plate 1421 in groups, each group of bristles 149 can be formed in a circular shape or a square shape or an oval shape along the edge of the circular plate 1421, and the width of the circular plate 1421 is controlled to be 10mm to 20 mm. The micro motor 1422 is connected to the center of the circular edge away from the bristle surface, and the micro motor 1422 ensures that the circular plate 1421 can rotate 360 degrees. The circular plate 1421 is also disposed on a bristle 149 plate, which forms an interior space with the housing 1423 for receiving the micro-motor 1422. The second brush 142 structure drives the bristles 149 to move through the rotation of the circular plate 1421, and the auxiliaries in the groove 13 are swept out by the movement of the bristles 149, so that all the auxiliaries added through the vibrating screen device 2 are ensured to be sprayed onto the non-woven fabric;

the brush 14 may be a combination of a first brush 141 and a second brush 142, which are vertically distributed above and below each other. The first brush 141 structure and the second brush 142 structure are combined on the same brush 14, so that an operator can adjust the brush 14 according to the type of the auxiliary agent, and when the first brush 141 structure is needed, the roller 12 can be moved to the position of the first brush 141 structure in the brush 14 or the first brush 141 structure of the brush 14 can be moved to the position corresponding to the roller 12, which corresponds to the second brush 142 structure.

On the contrary, the servo electric cylinder 140 is fixed on the sliding module 144 on the rail 145, and the brush 14 can reciprocate by the rail 145 arranged along the longitudinal direction of the roll shaft 12 in cooperation with the sliding module 144;

the brush 14 may also be a third brush 143, the third brush 143 includes bristle groups 1431, the bristle groups 1431 are distributed in rows along the longitudinal direction and are distributed in columns along the vertical direction, the single bristle group 1431 is a structure with two narrow ends and a wide middle along the longitudinal direction, and the transition from the two ends to the middle may be linear. While the width of the ends of the individual bristle set 1431 is less than the width of the groove 13 and the width in the middle is greater than the width of the groove 13. The third brush 143 can make the end of the bristle group 1431 enter the groove 13 more easily, and gradually transition to the extrusion brushing of the two sides of the groove 13, thereby avoiding the residue of the auxiliary agent in the groove 13.
