Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric smoothing technology, and in particular to a nonwoven fabric smoothing device. Background Technology

[0002] Nonwoven fabric (also known as non-woven cloth) is a flexible material made of oriented or randomly arranged fibers bonded together by mechanical, thermal, or chemical methods, combining the appearance and properties of cloth. Its characteristics include moisture resistance, breathability, flexibility, lightweight, flame retardancy, biodegradability, non-toxicity, environmental friendliness, rich colors, and low cost, making it widely used in medical, packaging, and other fields. However, existing production equipment is prone to wrinkling the surface of nonwoven fabrics during high-speed processing. Traditional processes often rely on the mechanical tension of the winding machine to passively smooth the surface and maintain its flatness.

[0003] In existing technologies, traditional smoothing processes in nonwoven fabric production mainly rely on the mechanical tension of the winding machine for passive flattening. The drawback of this method is that applying unidirectional tension to the material solely through winding tension cannot effectively eliminate localized wrinkles caused by uneven fiber distribution, heat-pressing deformation, or conveyor misalignment. Especially on high-speed production lines, the lag in mechanical tension can cause wavy undulations or edge curling on the nonwoven fabric surface, affecting product consistency and subsequent processing accuracy.

[0004] In response to this technical problem, this application proposes a nonwoven fabric smoothing device. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A nonwoven fabric smoothing device includes a processing table, a connecting frame fixedly connected to the top of the processing table, an electric hydraulic cylinder fixedly connected to the top of the inner wall of the connecting frame, a connecting platform fixedly connected to the drive end of the electric hydraulic cylinder, a motor fixedly connected to the rear end of the connecting platform, a smoothing wheel connected to the drive end of the motor via a straightening assembly, and fixing plates fixedly connected to both the left and right ends of the processing table.

The bottom end of the transmission gear is rotatably connected to the inner wall of the connecting platform, and the front end of the toothed plate one and the rear end of the toothed plate two are respectively meshed with the transmission gear.

[0015] This utility model has the following beneficial effects:

[0016] 1.

[0025] 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.

[0026] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a non-woven fabric smoothing device, comprising a processing table 1, a connecting frame 7 fixedly connected to the top of the processing table 1, an electric hydraulic cylinder 11 fixedly connected to the top of the inner wall of the connecting frame 7, a connecting platform 12 fixedly connected to the driving end of the electric hydraulic cylinder 11, a motor 16 fixedly connected to the rear end of the connecting platform 12, a smoothing wheel 22 connected to the driving end of the motor 16 via a straightening assembly, the straightening assembly including a rotating table 17 fixedly connected to the driving end of the motor 16, a fixed housing 23 fixedly connected to the front end of the rotating table 17, a screw 24 rotatably connected to the inner wall of the fixed housing 23, an adapter block 25 threadedly connected to the outer wall of the screw 24, and a sliding connection on the outer wall of the adapter block 25. A traction plate 18 is rotatably connected to the outer wall of the adapter block 25 on the inner wall of the fixed shell 23. A toothed plate 19 is rotatably connected to the bottom end of the traction plate 18. The top end of the toothed plate 19 is slidably connected to the rear side of the bottom end of the inner wall of the connecting platform 12. A toothed plate 21 is slidably connected to the front side of the bottom end of the inner wall of the connecting platform 12. A transmission gear 20 is meshed with the rear end of the toothed plate 21. The bottom end of the transmission gear 20 is rotatably connected to the inner wall of the connecting platform 12. The front end of the toothed plate 19 and the rear end of the toothed plate 21 are respectively meshed with the transmission gear 20. An electric hydraulic cylinder 23 is fixedly connected to the bottom end of the inner wall of the processing table 1. A support wheel frame 8 is fixedly connected to the drive end of the electric hydraulic cylinder 213. A transmission wheel 14 is rotatably connected to the outer wall of the support wheel frame 8.

[0027] Specifically: The nonwoven fabric smoothing device achieves dynamic adjustment smoothing control through the coordinated operation of multiple mechanisms. First, the electric hydraulic cylinder 13 is activated to drive the support wheel frame 8 to rise and fall vertically, so that the transmission wheel 14 installed at its end can accurately adjust the support height of the nonwoven fabric to form a stable non-contact bearing surface. Simultaneously, the electric hydraulic cylinder 11 is activated to drive the connecting platform 12 to descend, so that the two sets of symmetrically arranged smoothing wheels 22 can contact the surface of the nonwoven fabric with adjustable pressure. When motor 216 drives the rotating table 17 to rotate, the linkage between the adapter block 25 and the traction plate 18 drives the toothed plate 19 to move horizontally and reciprocally along the guide rail. The reciprocating motion is converted into the reverse displacement of the toothed plate 21 by the meshing of the transmission gear 20, thereby realizing the symmetrical opening and closing motion of the two smoothing wheels 22. The stroke limit of the adapter block 25 can be precisely adjusted by rotating the screw 24, thereby controlling the reciprocating amplitude of the toothed plate 19 and realizing stepless control of the pressure gradient of the smoothing wheel 22. This device, through the three-dimensional coordinated control of height, pressure and amplitude, not only ensures flexible contact with nonwoven fabrics of different weights, but also eliminates multi-directional stress wrinkles in high-speed production.

[0028] Reference Figure 2 and Figure 3The processing table 1 is fixedly connected to fixed plates 2 at both ends. The rear end of the left fixed plate 2 is fixedly connected to a motor 3. The drive end of the motor 3 is fixedly connected to a transmission pipe 4. The front end of the transmission pipe 4 is connected to an outer support plate 10 through a support group. The support group includes a second support plate 15 located on the outer wall of the transmission pipe 4 and rotatably connected to both ends. The opposite ends of the second support plate 15 are rotatably connected to the outer support plate 10. The front end of the transmission pipe 4 is threadedly connected to a screw 5. The outer wall of the screw 5 is rotatably connected to a transition ring 6. The outer wall of the transition ring 6 is rotatably connected to several support plates 9. The opposite ends of the outer support plates 10 are rotatably connected to the opposite ends of the support plates 9.

[0029] Specifically, the nonwoven fabric smoothing device's roll loading and unloading system adopts a modular mechanical linkage design. After the nonwoven fabric roll is placed on the outside of the outer support plate 10, the servo motor 3 drives the transmission tube 4 to rotate, and the worm gear reducer drives the roll to achieve axial uniform speed transmission. After the nonwoven fabric moves along the guide groove to the other side of the device, the operator rotates the precision adjusting screw 5, driving the adapter ring 6 to move axially along the threaded pair, thereby pulling the support plate 9 to retract centripetally along the dovetail guide rail. At this time, the support plate 15 forms a motion coupling with the support plate 9 through the hinge linkage mechanism. During the synchronous retraction of the bidirectional clamping surface of the outer support plate 10, the nonwoven fabric roll placed on its outside automatically slides off due to the sudden reduction of friction on the contact surface. This loading and unloading system, through the cooperation of screw fine adjustment and mechanical limit device 7, can achieve precise control of the retraction stroke of the outer support plate 10, which can ensure the rapid unloading of rolls of different diameters and avoid fiber layer damage caused by traditional knocking disassembly.

[0030] Working principle: After the non-woven fabric is fitted onto the outer side of the outer support plate 10, the transmission tube 4 is rotated by the motor 3 to transfer the non-woven fabric. After the non-woven fabric is transferred from one side to the other, the screw 5 is rotated to drive the support plate 9 to retract through the adapter ring 6. With the cooperation of the support plate 15 and the support plate 9, the outer support plate 10 retracts inward, thereby detaching the roll of non-woven fabric fitted onto the outer side of the outer support plate 10, facilitating the removal of the non-woven fabric. Meanwhile, the electric hydraulic cylinder 13 is activated to drive the support wheel frame 8 to rise and fall, so that the transmission wheel 14 at the support wheel frame 8 supports the non-woven fabric. When the electric hydraulic cylinder 11 is started, it drives the connecting platform 12 to descend, causing the smoothing wheel 22 to smooth the non-woven fabric. When the motor 16 is started, it drives the rotating platform 17 to rotate, which in turn drives the traction plate 18 through the adapter block 25 to move the toothed plate 19 back and forth. This causes the toothed plate 19 to drive the toothed plate 21 through the transmission gear 20, which in turn causes the smoothing wheel 22 to move relative to the non-woven fabric. The smoothing wheel 22 smooths the non-woven fabric. The rotating screw 24 can drive the adapter block 25 to adjust the reciprocating movement of the toothed plate 19 driven by the traction plate 18, so as to adjust the smoothing force of the smoothing wheel 22.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
