Description

A feeding device for a nonwoven fabric flat-edge machine Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a feeding device for a nonwoven fabric flat-edge machine. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is made of polyester fiber. Before being made into various products, it needs to be fed and cut by a flat-end machine to ensure a smooth cut surface, which can be used to make various products.

[0003] Chinese Patent Publication No. 222160751 U, published on December 13, 2024, discloses a nonwoven fabric cutting device, relating to the field of nonwoven fabric cutting technology. This device addresses the problem that existing cutting devices lack a structure to smooth out wrinkles during use. The device includes a cutting assembly; the cutting assembly is the main body of the cutting device, with a rectangular structure; two sets of mounting components are installed on the winding assembly, with the mounting parts fixedly installed on the upper and lower sides of a fixing member on the winding assembly; a moving component is installed on the mounting components; the moving component is slidably mounted inside the rotating groove via a top spherical protrusion; and a pushing component is fixedly installed at the bottom of the moving component. The drawback of this technical solution is that it is difficult to ensure the flatness of the nonwoven fabric before cutting, leading to easy deformation and distorted cuts.

[0004] In summary, the existing feeding device has the drawback of poor feeding flatness, which can easily lead to cutting deformation. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of existing feeding devices, which have poor feeding flatness and are prone to cutting deformation. It provides a feeding device for nonwoven fabric flat-end machines that improves feeding flatness and prevents cutting deformation.

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

[0007] A feeding device for a nonwoven fabric flat-edge machine includes a frame; a feeding roller rotatably connected to the frame; a tension roller rotatably connected to the frame, with the feeding roller positioned on one side of the tension roller; a tension adjusting rod, with a fixed plate connected to the frame, a support frame connected to the tension roller, one end of the tension adjusting rod rotatably connected to the fixed plate, and the other end threadedly connected to the support frame; the tension roller being vertically movable to the frame via the tension adjusting rod; a conveying roller rotatably connected to the frame, positioned on the other side of the tension roller; a metering plate connected to the frame, with a fixed plate on one side and a movable plate on the other side; a top plate vertically movable to the frame, and the movable plate vertically and horizontally movable to the frame.

[0008] The feed roller, rotatably connected to the frame, winds, stores, and feeds the nonwoven fabric roll. The tension of the nonwoven fabric between the feed roll and the feed roller is adjusted by a tension roller. Additionally, a tension adjustment rod allows for quick adjustment of the tension roller's height, thereby adjusting its tension. The tension adjustment rod rotates on a support frame to adjust both ends of the tension roller, improving adjustment efficiency and convenience. A quantitative pad is used to lay the nonwoven fabric fed by the feed roller, ensuring it lies stable under the cutter of the flat-end cutter. The fixed plate presses and fixes one end of the laid-out nonwoven fabric, while the moving plate, by attaching to and moving on the nonwoven fabric, flattens it, preventing wrinkles and displacement during cutting. This allows the nonwoven fabric to be stably unfolded and ready for cutting. This achieves the effects of improving feeding flatness, preventing cutting deformation, improving cut smoothness, and enhancing operational efficiency and convenience through structural adjustments.

[0009] Preferably, the support frame includes a flat plate and side plates. The side plates have insertion holes, and a tension roller is connected to a rotating rod that inserts into the insertion holes. A guide groove is provided on the frame, and the rotating rod is slidably connected to the guide groove. The end of the flat plate is connected to the side plate. The flat plate and side plates in the support frame are connected in a gantry structure. The side plates are inserted into the rotating rod, which passes through the guide groove, via insertion holes. The up-and-down movement of the flat plate causes the side plates to move up and down on the guide groove, thereby achieving directional tension adjustment. This improves the stability of the connection and adjustment operation between the support frame structures.

[0010] Preferably, the plate has mounting holes, which are connected to a connecting post. The connecting post has an adjusting screw hole, and a tension adjusting rod is threaded into this hole. The fixed plate has a positioning rotating hole, and a rotating block is connected to the tension adjusting rod. The rotating block is rotatably connected to the positioning rotating hole. The connecting post increases the load-bearing capacity of the tension adjusting rod. Both the tension adjusting rod and the rotating block are cylindrical with a T-shaped connection section, ensuring stable rotation of the tension adjusting rod and the driving rotating block on the fixed plate. This, in turn, ensures the connecting post drives the plate to move up and down, thus improving the stability of tension adjustment.

[0011] Preferably, the frame has a rotating hole, and the feed roller is connected to a second rotating rod, which is inserted into the rotating hole. The frame is connected to a conveying base and a first driving mechanism. The second rotating rod is connected to the first driving mechanism. The conveying base has a feeding trough, and the feed roller is rotatably connected to the feeding trough. The frame is stably connected to the feed roller via the rotating hole and the second rotating rod. The first driving mechanism is connected to the second rotating rod to drive the feed roller to rotate and push the nonwoven fabric between the conveying bases, completing the conveying process. The feeding trough is used to place the nonwoven fabric and to fit it against the feed roller. This ensures stable conveying of the nonwoven fabric.

[0012] Preferably, the feed roller is connected to an anti-slip sleeve, and the feed trough has an L-shaped cross-section with a chamfered joint at the interface. The anti-slip sleeve is fitted onto the feed roller to buffer and increase the contact friction with the nonwoven fabric, preventing slippage. The chamfering makes the surface of the conveyor base curved, resulting in smoother nonwoven fabric conveying. This achieves the effects of protecting the nonwoven fabric and improving the smoothness and stability of the feeding process.

[0013] Preferably, the frame is equipped with a pressing slide rail, which has a placement groove. The moving plate and fixed plate are inserted into the placement groove, and the moving plate is slidably connected to the pressing slide rail. The frame, through the pressing slide rail, allows the moving plate to move directionally against the groove to flatten and unfold the nonwoven fabric surface. A groove is cut on one side of the pressing slide rail to form the placement groove, facilitating the placement of unused fixed and moving plates, thereby facilitating the feeding of the nonwoven fabric by the feed rollers. This achieves the effect of ensuring continuous feeding and improving the smoothness of feeding.

[0014] Preferably, the frame includes a pressure plate and a movable plate. The movable plate is movably connected to the frame. One end of the pressure plate is connected to the end of the movable plate, and the other end of the pressure plate has a pressure groove and a locking groove. The fixed plate is slidably connected to the pressure groove, and the movable plate is connected to the locking groove. The frame connects the movable plate via the pressure plate. The pressure groove is an L-shaped recessed groove with openings on both sides, and the locking groove is a recessed groove with openings on one side. This allows the locking groove to engage with the movable plate, which is placed within the pressure groove. As the locking groove moves with the movable plate in the pressing slide rail, the pressure groove continuously presses against the brake plate to fix the nonwoven fabric. This ensures the nonwoven fabric is laid flat and prevents wrinkles and displacement during cutting.

[0015] Preferably, the frame is equipped with a telescopic mechanism and a second drive mechanism. The second drive mechanism is connected to the frame and has a drive rod. The moving plate has a second screw hole, and the drive rod is threaded into the second screw hole. The telescopic mechanism is connected to the moving plate. The pressure plate is connected to a linkage plate. The moving plate has a moving slide rail. The linkage plate is connected to a slider plate, which is slidably connected to the moving slide rail. The telescopic mechanism is connected to the linkage plate. The moving plate is connected to a connecting rod. The frame is connected to a limit groove, and the connecting rod is slidably connected to the limit groove. The second drive mechanism rotates the drive rod, thereby driving the moving plate to move, thus ensuring that the moving plate can move horizontally. The telescopic mechanism is fixed on the moving plate and connected to the linkage plate connected to the pressure plate, allowing the linkage plate to move up and down within the moving plate. The slider plate ensures vertical stability and horizontal synchronization. The limit groove prevents the fixed plate from moving vertically while ensuring horizontal stability. This achieves the effect of improving the connection between structures and operational stability.

[0016] The beneficial effects of this utility model are: improving the flatness of the feeding and preventing cutting deformation, thereby improving the flatness of the cut; structural adjustment to improve work efficiency and convenience; improving the stability of tension adjustment; ensuring the stability of non-woven fabric conveying; ensuring continuous feeding and improving feeding smoothness; preventing wrinkles and displacement during cutting; and improving the connection between structures and the stability of operation.

The flat plate 10 has a mounting hole 13, which is connected to a connecting post 14. The connecting post 14 has an adjusting screw hole 1, and the tension adjusting rod 4 is threadedly connected to the adjusting screw hole 1. The fixed plate 5 has a positioning rotating hole, and the tension adjusting rod 4 is connected to a rotating block 15, which is rotatably connected to the positioning rotating hole.

[0029] As shown in Figures 1 and 3, the frame 1 has a rotating hole, and the conveying roller 6 is connected to a rotating rod 16, which is inserted into the rotating hole. The frame 1 is connected to a conveying base 17 and a drive mechanism 18. The rotating rod 16 is connected to the drive mechanism 18. The conveying base 17 has a feeding trough 19, and the conveying roller 6 is rotatably connected to the feeding trough 19. The conveying roller 6 is connected to an anti-slip sleeve 20. The cross-sectional shape of the feeding trough 19 is L-shaped, and the joint of the connecting surface of the feeding trough 19 has a chamfered structure.

[0030] As shown in Figures 1 and 4, the frame 1 is provided with a pressing slide rail 21, the pressing slide rail 21 is provided with a placement slide groove 22, the moving plate 9 and the fixed plate 8 are inserted into the placement slide groove 22, and the moving plate 9 is slidably connected to the pressing slide groove 21.

[0031] As shown in Figures 1 and 2, the frame 1 is provided with a pressure plate 23 and a movable plate 24. The movable plate 24 is movably connected to the frame 1. One end of the pressure plate 23 is connected to the end of the movable plate 24. The other end of the pressure plate 23 is provided with a pressure groove 25 and a slot 26. The fixed plate 8 is slidably connected to the pressure groove 25, and the movable plate 9 is connected to the slot 26.

[0032] As shown in Figures 1 and 2, the frame 1 is provided with a telescopic mechanism 27 and a second drive mechanism 28. The second drive mechanism 28 is connected to the frame 1 and is connected to a drive rod 29. The movable plate 24 is provided with a second screw hole, and the drive rod 29 is threadedly connected to the second screw hole. The telescopic mechanism 27 is connected to the movable plate 24. The pressure plate 23 is connected to a linkage plate 30. The movable plate 24 is provided with a movable slide rail 31. The linkage plate 30 is connected to a slider plate 32, and the slider plate 32 is slidably connected to the movable slide rail 31. The telescopic mechanism 27 is connected to the linkage plate 30, and the movable plate 24 is connected to a connecting rod 33. The frame 1 is connected to a limit slide groove 34, and the connecting rod 33 is slidably connected to the limit slide groove 34.

[0033] As shown in Figures 1-4: Drive mechanism 18 and drive mechanism 28 both adopt existing rotary motor structures, telescopic mechanism 27 adopts existing cylinder structure, and anti-slip sleeve 20 is made of rubber material with high friction in contact with non-woven fabric, so as to transport non-woven fabric through rotation in contact.

[0034] The fixed plate 8 is connected to the connecting slider 35, and the pressure plate 23 is connected to the connecting groove 36. The connecting slider 35 and the connecting groove 36 are slidably connected. The structural shape of the connecting slider 35 and the connecting groove 36 is T-shaped to prevent the connecting slider 35 from falling out of the connecting groove 36. At the same time, the connecting slider 35 can move horizontally on the pressure plate 23.

[0035] The fixed plate 8 is connected to a locking block 37, and the pressing slide 21 is provided with a limiting groove 38. The locking block 37 and the limiting groove 38 are matched in size, so that the locking block 37 enters the limiting groove 38 when the fixed plate 8 is pressed down, and the fixed plate 8 is prevented from moving along with the pressure plate 23 under friction, which would cause the fabric to wrinkle.

[0036] The frame 1 is equipped with a cutting device (not shown in the figure), which is positioned above the metering pad 7 to cut the nonwoven fabric that is unfolded and flattened on the metering pad 7.

[0037] In use: First, the head of the nonwoven fabric roll on the feeding roller 2 is passed through the tension roller and finally extends from the feeding trough 19 to part of the quantitative pad 7. The conveying roller 6 presses the nonwoven fabric with the anti-slip sleeve 20. The head of the nonwoven fabric is vertically aligned and flush with the fixed plate 8 above. Rotate the tension adjusting rod 4 to adjust the height of the tension roller 3 so that the nonwoven fabric has a certain tension, thus completing the pre-feeding of the nonwoven fabric. Start the drive mechanism 28 to convey the head of the nonwoven fabric on the quantitative pad 7 to the required length and stop. Start the telescopic mechanism 27 to press down the linkage plate 30, which in turn presses down the connected pressure plate 23, causing the slider plate 32 to move along the slide rail. 31 moves downwards, and the fixed plate 8 and the moving plate 9 press on the nonwoven fabric. The locking block 37 of the fixed plate 8 enters the limiting groove 38, and the drive mechanism 28 is activated, causing the drive rod 29 to rotate. Then, the moving plate 23, which is threadedly connected to the drive rod 29, moves. At this time, the pressure plate 23 leads the moving plate 9 to move on the nonwoven fabric (the moving plate 9 moves on the pressure slide rail 21, the fixed plate 8 moves relative to the pressure groove 25, the connecting rod 33 moves in the limiting slide groove 34, and the connecting slider 35 moves in the connecting slide groove 36). This makes the nonwoven fabric more even and less prone to deformation when the moving plate 9 applies force to cooperate with the fixed plate 8 to lay the fabric, thus completing the feeding and waiting for cutting operations before the nonwoven fabric is cut.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
