Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric edge pressing technology, specifically to an edge pressing device for nonwoven fabric. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It is a new generation of environmentally friendly material, characterized by its moisture resistance, breathability, flexibility, lightweight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability. It is often produced using polypropylene granules as raw material through a continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing. It is called "cloth" because it resembles the appearance and some properties of fabric.

[0003] According to announcement number CN 216474050 U, a pressing device for nonwoven fabrics is proposed. Addressing the issue that existing pressing devices have poor positioning effects on nonwoven fabrics, leading to wrinkles during pressing, the following solution is proposed: A workbench is included. A support plate is fixedly installed on the rear side of the workbench. A horizontal plate is fixedly installed on the top of the support plate. A threaded rod is rotatably installed on the top of the horizontal plate. A threaded cap is threadedly connected to the outer side of the threaded rod. The outer side of the threaded cap is slidably connected to the inner side of the horizontal plate. A rotating shaft is rotatably installed inside the threaded cap. Two pressing wheels are fixedly installed on the outer side of the rotating shaft. Four L-shaped plates are slidably installed on the inner wall of the workbench.

[0004] The device has a reasonable structural design. The motor drives the threaded rod to rotate, which in turn moves the threaded cap horizontally, causing the pressing wheel to move synchronously. It can perform edge pressing on non-woven fabrics with high reliability. However, this device lacks an effective tension adjustment mechanism. When pressing non-woven fabrics, uneven tension can easily lead to poor edge pressing results, wrinkles, deformation, and other problems, affecting product quality. In addition, some devices have unreasonable edge pressing mechanism designs, resulting in low edge pressing efficiency and difficulty in ensuring the uniformity and stability of edge pressing.

The first and second rotating rollers are symmetrically distributed from left to right, and the non-woven fabric is above the first and second rotating rollers and below the lifting roller, forming a V-shape.

[0014] Compared with the prior art, the present invention provides a pressing device for nonwoven fabrics, which has the following advantages:

[0015] 1. This nonwoven fabric edge-pressing device uses a tension adjustment mechanism driven by a first servo motor to rotate a lead screw, causing the lifting plate to move up and down along a limit rod, thus changing the position of the lifting roller. Since the nonwoven fabric forms a V-shape between the first and second rotating rollers and the lifting roller, adjusting the height of the lifting roller changes the tension of the nonwoven fabric. This design allows for precise control of the nonwoven fabric tension according to different production needs, avoiding problems such as wrinkles and deformation caused by uneven tension, ensuring the flatness of the nonwoven fabric during the edge-pressing process, and improving product quality.

[0016] 2. This nonwoven fabric edge-pressing device, in which a second servo motor drives a rotating shaft to rotate, and through the meshing transmission of a third gear with the second and first gears, achieves synchronous rotation of the first and second electric heating rollers. The first and second electric heating rollers heat and compress the nonwoven fabric, causing the edges of the nonwoven fabric to melt and compact, forming a firm edge. Simultaneously, the third and fourth rotating rollers further transport and refine the edge-pressed nonwoven fabric, ensuring a smooth surface and neat edges, improving production efficiency and product aesthetics.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1-3 This utility model provides a technical solution: a pressing device for non-woven fabric, including a fixed base 1, a first rotating roller 2 rotatably connected to the front and rear sides of the inner wall of the fixed base 1 near the top left side, a second rotating roller 3 rotatably connected to the front and rear sides of the inner wall of the fixed base 1 near the top right side, a tension adjustment mechanism 4 provided at the top of the fixed base 1, and a pressing mechanism 5 provided on the inner wall of the fixed base 1.

[0031] The top of the lifting plate 45 has a hole that matches the limiting rod 46, and the lifting plate 45 is slidably connected to the surface of the limiting rod 46 through the hole.

[0032] The top of the fixed plate 41 has a groove that matches the lifting column 47, and the surface of the lifting column 47 is slidably connected to the groove. The first roller 2 and the second roller 3 are symmetrically distributed from left to right. The non-woven fabric is above the first roller 2 and the second roller 3 and below the lifting roller 49, forming a V-shape.

[0033] Example 2

[0034] Please see Figure 4-5 Furthermore, based on Example 1, the edge pressing mechanism 5 is obtained.

[0035] The pressing mechanism 5 includes a first electric heating roller 51 and a second electric heating roller 52. The first electric heating roller 51 is symmetrically rotatably connected to the front and rear sides of the inner wall of the fixed frame 42 near the left side. The second electric heating roller 52 is symmetrically rotatably connected to the front and rear sides of the inner wall of the fixed frame 42 near the left side. A first gear 53 is fixedly connected to one end of the surface of the first electric heating roller 51. A second gear 54 is fixedly connected to one end of the surface of the second electric heating roller 52. A rotating shaft 55 is rotatably connected to the front and rear sides of the inner wall of the fixed frame 42 near the left side. A third gear 56 is fixedly connected to the surface of the rotating shaft 55 near both ends. An L-plate 57 is fixedly connected to the front of the fixed base 1 near the bottom left side. A second servo motor 58 is fixedly connected to the front of the L-plate 57. A third rotating roller 59 is rotatably connected to the front and rear sides of the inner wall of the fixed frame 42 near the right side. A fourth rotating roller 511 is rotatably connected to the front and rear sides of the inner wall of the fixed frame 42 near the right side.

[0036] The inner wall of the fixed frame 42 has holes on the front and rear sides that match the first electric heating roller 51 and the second electric heating roller 52, and the surfaces of the first electric heating roller 51 and the second electric heating roller 52 are respectively penetrated and rotatably connected in the corresponding holes. The first electric heating roller 51 is located above the second electric heating roller 52, and the first gear 53 meshes with the second gear 54.

[0037] The inner wall of the fixed frame 42 has holes on the front and rear sides near the bottom left side that match the rotating shaft 55. The rotating shaft 55 passes through the surface and is rotatably connected in the holes. The third gear 56 meshes with the second gear 54. The output end of the second servo motor 58 is fixedly connected to the front end of the rotating shaft 55. The third roller 59 is located above the fourth roller 511.

[0038] In actual operation, when this device is used, the first step in the nonwoven fabric conveying and tension adjustment process is the pressing of the nonwoven fabric. The nonwoven fabric is placed above the first roller 2 and the second roller 3, and below the lifting roller 49, forming a V-shaped conveying path. When it is necessary to adjust the tension of the nonwoven fabric, the first servo motor 43 is started. The output end of the first servo motor 43 drives the lead screw 44 to rotate. Since the lead screw 44 is threadedly connected to the lifting plate 45, and the lifting plate 45 slides along the limit rod 46 through the hole at the top that matches the limit rod 46, while the lifting column 47 slides up and down in the groove at the top of the fixed plate 41, the lifting plate 45 moves up and down when the lead screw 44 rotates, thereby driving the lifting frame 48 and the lifting roller 49 to rise and fall, changing the tension of the nonwoven fabric, and achieving precise adjustment of the nonwoven fabric tension. Then, the nonwoven fabric with the adjusted tension enters the pressing mechanism 5 for pressing. The second servo motor 58 is activated, and its output drives the rotating shaft 55 to rotate. The third gear 56 on the surface of the rotating shaft 55 meshes with the second gear 54 on the surface of the second electric heating roller 52. Simultaneously, the second gear 54 meshes with the first gear 53 on the surface of the first electric heating roller 51. Through gear transmission, the first electric heating roller 51 and the second electric heating roller 52 rotate synchronously. The first electric heating roller 51 and the second electric heating roller 52 heat and compress the nonwoven fabric, using the principle of hot pressing to melt and compact the edges of the nonwoven fabric, completing the edge pressing operation. The edge-pressed nonwoven fabric continues to be conveyed by the third rotating roller 59 and the fourth rotating roller 511. The third rotating roller 59 is located above the fourth rotating roller 511. The two work together to smoothly output the edge-pressed nonwoven fabric, completing the entire edge pressing process of the nonwoven fabric. Throughout the entire operation, the rotational connection and precise cooperation of each component ensure that the nonwoven fabric can smoothly complete the tension adjustment, edge pressing, and other processes, efficiently and stably meeting the production requirements of nonwoven fabric edge pressing.
