Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric production equipment, and in particular to an adjustable cross-laying machine for nonwoven fabric webs. Background Technology

[0002] Nonwoven fabric webs are sheet-like or mesh-like structures formed by oriented or randomly arranged fibers (such as polyester fibers, polyester fiber, etc.). They are the core component of nonwoven fabrics. Cross-laying of nonwoven fabric webs is a key process for improving the mechanical properties of nonwoven fabrics. The layup angle and spacing of the webs need to be adjusted according to product requirements. Traditional layup machines have a narrow adjustment range and poor adaptability: their layup angles are mostly fixed and cannot achieve arbitrary angle fine-tuning; the adjustment time for layup spacing is long and it is difficult to adapt to the production needs of small batches and multiple varieties. In addition, the large deviation of the layup angle can easily cause uneven thickness and large strength differences in the nonwoven fabric, resulting in low product qualification rate. Therefore, this application proposes an adjustable cross-laying machine for nonwoven fabric webs. Utility Model Content

[0021] Example 1 like Figure 1 and Figure 2 As shown, this utility model proposes an adjustable cross-laying machine for nonwoven fabric webs, including a support frame 1. A top conveyor plate 2 is fixedly connected to the top of the support frame 1. A laying mechanism is provided at the top of the top conveyor plate 2. The laying mechanism includes limiting slide bars 9 fixed to both sides of the top of the top of the top conveyor plate 2. Multiple sliders 10 are slidably connected to the outer walls of the two limiting slide bars 9. Fixed supports 11 are fixedly connected to the top of the multiple sliders 10. The multiple fixed supports 11 are arranged in pairs. The support frame 1 is made of high-strength steel structure to provide stable support for the entire equipment and avoid laying deviation caused by vibration during the laying process. The top conveyor plate 2 is fixed at the top and serves as the core platform for the laying operation. The surface is coated with a wear-resistant polytetrafluoroethylene coating to reduce friction between the web and the platform and prevent damage to the web. The limiting slide bars 9 are fixed to both sides of the top of the top of the top conveyor plate 2, and multiple sliders 10 are slidably connected to the outer walls. Fixed supports 11 are fixed to the top of the sliders 10. The sliders 10 can slide laterally along the limiting slide bars 9 to adjust the spacing of each set of fixed supports 11, thereby adapting to different webs.

[0022] In addition, such as Figure 2 , Figure 3 and Figure 4As shown, a transmission structure is provided between multiple fixed supports 11. The transmission structure includes a limiting slide rod 14 fixed between each group of fixed supports 11 by a buckle 12. Both sides of the outer wall of the multiple limiting slide rods 14 are penetrated by a stop block 13. A hydraulic pump 15 is provided at the top of one of the fixed supports 11. The output ends of the two hydraulic pumps 15 are connected to hydraulic push blocks 16 via hydraulic rods. The bottom ends of the hydraulic push blocks 16 are fixedly connected to fixed support frames 17. The outer wall of the fixed support frame 17 penetrates the outer wall of the limiting slide rod 14. The bottom end of the fixed support frame 17 slides... A sliding frame 18 is dynamically connected. An electric telescopic rod 19 is fixedly connected to the top of the sliding frame 18. A connecting terminal 20 is fixedly connected to the bottom of the electric telescopic rod 19. A rotating joint 21 is bolted to the inner wall of the connecting terminal 20. A push seat 22 is fixedly connected to one end of the rotating joint 21. A sliding block 24 is fixedly connected to one side of the outer wall of the push seat 22. The sliding block 24 is slidably connected to a sliding groove 25 fixed to one side of the sliding frame 18. A stacking clamp 23 is fixedly connected to the bottom of the push seat 22. The connecting terminal 20 is connected to the push seat 22 via the rotating joint 21. 2. The rotating joint 21 can rotate at an angle. Through the extension and retraction of the electric telescopic rod 19 and the cooperation of the rotating joint 21, the layup angle of the layup clamp 23 can be adjusted to meet the requirements of different products for the cross angle of the fiber web. The sliding block 24 is slidably connected to the sliding groove 25 to ensure the stability of the push seat 22 during movement and to prevent angular deviation. Each set of fixed supports 11 is fixed to the limiting slide rod 14 by a buckle 12. Stops 13 penetrate both sides of the outer wall of the limiting slide rod 14, limiting the sliding range of the fixed support 17 and preventing over-adjustment. The hydraulic pump 15... The hydraulic pusher 16 is driven by a hydraulic rod, which drives the fixed support 17 to slide along the limiting slide bar 14, thereby adjusting the lateral spacing of the laying clamp 23 to ensure uniform fiber web laying spacing. The bottom end of the fixed support 17 is slidably connected to the sliding frame 18, and the top end of the sliding frame 18 is fixed with an electric telescopic rod 19. The electric telescopic rod 19 can precisely control the extension length. Through the connecting terminal 20 and the rotating joint 21, it drives the laying clamp 23 to move up and down, adjusting the pressure on the fiber web during laying, avoiding excessive pressure that causes fiber web deformation, or insufficient pressure that causes fiber web to be poorly positioned.

[0023] It is necessary to add that, such as Figure 1As shown, the top of the top conveyor plate 2 is provided with a guide structure between multiple fixed supports 11. The guide mechanism includes side partitions 8 fixed to both sides of the top of the top of the top conveyor plate 2. The inner wall of the side partitions 8 is provided with a transmission device 3. The outer wall of the support frame 1 is fixedly connected to a fixed frame 4. The top of the fixed frame 4 is rotatably connected to a conveyor roller 5. The outer wall of the support frame 1 is fixedly connected to a fixed frame 6 on one side of the fixed frame 4. The inner wall of the fixed frame 6 is rotatably connected to a conveyor roller 7. The outer wall of the support frame 1 is fixed with the fixed frame 4 and the fixed frame 6, and the conveyor roller 5 and the conveyor roller 7 are installed respectively. The conveyor roller 5 is used to receive the non-woven fabric web from the previous process. The conveyor roller 7 is used to transport the laid-up web to the subsequent hot pressing process to achieve continuous production. The side partitions 8 are fixed on both sides of the top conveyor plate 2. The inner wall is provided with a transmission device 3, which can drive the laying-up mechanism to move along the conveying direction to ensure that the laying-up and conveying rhythms are synchronized.

[0024] In this embodiment, when using this device, the control slider 10 slides along the limiting slide bar 9, the spacing of the fixed support 11 is adjusted to match the width of the fiber web, and then the hydraulic pump 15 is started to drive the fixed support frame 17 to move along the limiting slide bar 14, the lateral spacing of the laying clamp 23 is adjusted, and the angle of the laying clamp 23 is adjusted to a suitable angle through the cooperation of the electric telescopic rod 19 and the rotating joint 21. The transmission device 3 and the first and second conveyor rollers 5 and 7 are started. The non-woven fiber web produced in the previous process is conveyed to the top conveyor plate 2 through the first conveyor roller 5. The side partition 8 prevents the fiber web edge from being damaged. The transmission device 3 drives the laying mechanism to move along the conveying direction of the top conveyor plate 2. Under the drive of the hydraulic pump 15 and the electric telescopic rod 19, the laying clamp 23 lays the fiber web crosswise at a preset angle and spacing. During the laying process, the electric telescopic rod 19 adjusts the laying pressure in real time, and the rotating joint 21 keeps the angle stable to avoid angle deviation due to equipment vibration. The laid fiber web is conveyed to the subsequent hot pressing reinforcement process through the second conveyor roller 7 to achieve continuous production.

[0025] The above specific embodiments are merely several optional embodiments of this utility model.
