Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and specifically to a mesh curtain device for nonwoven fabric production. Background Technology

[0002] Nonwoven fabric production mesh curtains are key components in the web-forming process, mainly used for conveying, laying, and reinforcing the fiber web. During use, it is necessary to ensure the tension and offset of the mesh curtain. If the tension is too large, the offset may increase the friction between the mesh curtain and the frame, potentially tearing the mesh curtain body. Moreover, offset can lead to uneven distribution of the nonwoven fabric fiber web, producing scraps or defective products and increasing raw material loss. Therefore, it is necessary to design a nonwoven fabric production mesh curtain device that can adjust the position of the mesh curtain when it is offset. Utility Model Content

[0003] The purpose of this invention is to provide a mesh curtain device for nonwoven fabric production, which has the advantage of being able to adjust the position of the mesh curtain when its position shifts.

[0004] The technical solution adopted is as follows: A mesh curtain device for nonwoven fabric production includes a frame, a mesh curtain, a tension roller, two support rollers, and a shifting mechanism. Both support rollers are rotatably mounted on the frame. The tension roller is rotatably mounted below one of the support rollers. The mesh curtain is installed outside the tension roller and the two support rollers. There are two shifting mechanisms, each mounted on one of the two support rollers. Each shifting mechanism includes a shifting block, a telescopic mechanism, and a pushing ring. The support roller has an internal cavity and a long groove on its side. The shifting block is slidably positioned within the long groove. The telescopic mechanism is located inside the support roller. Support tubes are coaxially mounted at both ends of the support roller. Fixed rods extending from the support tubes to the outside and connected to the frame are located at both ends of the telescopic mechanism. The telescopic mechanism is connected to the pushing ring. The inner side of the shifting block has a groove, and the pushing ring is positioned within the groove.

[0005] Preferably, the telescopic mechanism is an electric telescopic rod, and the power cord and control cord of the electric telescopic rod extend along the fixed rod to the outside of the support roller.

[0006] Preferably, the movable block is divided into inner and outer parts, with the inner part being convex and the outer part being straight. The inner and outer parts are connected by bolts, and the inner convex part slides in the long groove.

[0007] Preferably, the two ends of the outer part are provided with rounded corners.

[0008] Preferably, all bolts are countersunk bolts.

[0009] Preferably, the outer end of the external part is provided with a silicone pad.

[0010] Compared to existing technologies, the advantages are: This invention utilizes a movable block slidably disposed on the side of the support roller to adjust the position of the mesh curtain on the support roller. This can adjust the position of the mesh curtain if it is misaligned, avoiding friction between the mesh curtain and the frame due to misalignment, and also preventing uneven distribution of nonwoven fiber web caused by mesh curtain misalignment.

[0012] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 4 As shown: Example 1: A mesh curtain device for nonwoven fabric production includes a frame 1, a mesh curtain, a tension roller 2, two support rollers 3, and a shifting mechanism. The two support rollers 3 are rotatably mounted on the frame 1. The frame 1 is equipped with a drive mechanism connected to both support rollers 3. The drive mechanism drives the two support rollers 3 to rotate at the same speed and in the same direction. The tension roller 2 is rotatably mounted below one of the support rollers 3. The mesh curtain is installed outside the tension roller 2 and the two support rollers 3. The frame 1 is equipped with a lifting mechanism. The tension roller 2 is mounted on the lifting mechanism. The lifting mechanism tensions the mesh curtain by lowering the tension roller 2.

[0013] There are two shifting mechanisms, which are respectively installed on two support rollers 3. Each shifting mechanism includes a shifting block 4, a telescopic mechanism 5, and a pushing ring 6. The support roller 3 has a cavity inside and a long groove 7 on its side. The shifting block is slidably disposed in the long groove 7. The telescopic mechanism 5 is disposed inside the support roller 3. Support tubes 8 are coaxially disposed at both ends of the support roller 3. Fixed rods 9 are disposed at both ends of the telescopic mechanism 5, extending from the support tubes 8 to the outside and connected to the frame 1. The telescopic mechanism 5 is connected to the pushing ring 6. The inner side of the shifting block has a groove 11. The pushing ring 6 is disposed in the groove 11. The telescopic mechanism 5 and the pushing ring 6 are inside the support roller 3 and do not rotate with the support roller 3.

[0014] When the mesh curtain shifts, the telescopic mechanism 5 extends to control the moving block that is slidably set on the side of the support roller 3 to adjust the position of the mesh curtain on the support roller 3. This can adjust the position of the mesh curtain that has shifted, avoid friction between the mesh curtain and the frame 1 due to the shift, and also avoid uneven distribution of nonwoven fiber web due to the shift of the mesh curtain.

[0015] Example 2: A mesh curtain device for nonwoven fabric production includes a frame 1, a mesh curtain, a tension roller 2, two support rollers 3, and a shifting mechanism. The two support rollers 3 are rotatably mounted on the frame 1. The frame 1 is equipped with a drive mechanism connected to both support rollers 3. The drive mechanism drives the two support rollers 3 to rotate at the same speed and in the same direction. The tension roller 2 is rotatably mounted below one of the support rollers 3. The mesh curtain is installed outside the tension roller 2 and the two support rollers 3. The frame 1 is equipped with a lifting mechanism. The tension roller 2 is mounted on the lifting mechanism. The lifting mechanism tensions the mesh curtain by lowering the tension roller 2.

[0016] There are two shifting mechanisms, which are respectively installed on two support rollers 3. Each shifting mechanism includes a shifting block 4, a telescopic mechanism 5, and a push ring 6. The support roller 3 has a cavity inside and a long groove 7 on its side. The shifting block is slidably disposed in the long groove 7. The telescopic mechanism 5 is disposed inside the support roller 3. Support tubes 8 are coaxially disposed at both ends of the support roller 3. Fixed rods 9 are disposed at both ends of the telescopic mechanism 5, extending from the support tubes 8 to the outside and connected to the frame 1. The telescopic mechanism 5 is connected to the push ring 6.

[0017] The telescopic mechanism 5 is an electric telescopic rod. The power cord and control line of the electric telescopic rod extend along the fixed rod 9 to the outside of the support roller 3. The moving block is divided into inner and outer parts. The inner part is convex and the outer part is straight. The inner and outer parts are connected by bolts. The protruding part of the inner part slides in the long groove 7. The two ends of the outer part are rounded. All bolts are countersunk bolts. The outer end of the outer part is provided with a silicone pad 10. The inner side of the moving block has a groove 11. The push ring 6 is set in the groove 11. The telescopic mechanism 5 and the push ring 6 are inside the support roller 3 and do not rotate with the support roller 3.

[0018] The working principle is as follows: When the mesh curtain needs to be tensioned, the lifting mechanism is controlled to descend, which drives the tensioning roller 2 to descend and tension the mesh curtain. When the mesh curtain shifts, the telescopic mechanism 5 extends, thereby controlling the push ring 6 to move, which in turn drives the moving block to move. The moving block, which is slidably set on the side of the support roller 3, adjusts the position of the mesh curtain on the support roller 3. This can adjust the position of the mesh curtain that has shifted, avoid friction between the mesh curtain and the frame 1 due to the shift, and also avoid uneven distribution of nonwoven fiber web due to the shift of the mesh curtain.

[0019] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
