Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology in the textile industry, and in particular to a needle-punching density control positioning block. Background Technology

[0002] In the production process of nonwoven fabrics, composite materials and other fields, needle punching is a key technology for material reinforcement and performance improvement. Taking needle-punched nonwoven fabric as an example, the fibers in the fiber web are entangled by the piercing action of the needles, thereby obtaining a finished product with a certain strength and density. In the preparation of high-performance composite materials such as carbon ceramic brake disc preforms, precise control of needle punching density directly affects the mechanical properties and service life of the product.

[0003] Currently, traditional needle density control positioning blocks generally suffer from problems such as low adjustment efficiency, significant accuracy decay, and poor equipment compatibility. Some positioning blocks rely on manual adjustment of the needle spacing, which is not only cumbersome and time-consuming, but also easily affected by human factors, resulting in uneven needle density. During long-term high-frequency use, mechanical wear between the positioning block and the needle can lead to positioning deviation, making it difficult to maintain stable needle density. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides a needle density control positioning block, including a fixed plate 1, a control console 2 fixedly connected to the upper surface of the fixed plate 1, a first button 3 fixedly connected to the upper surface of the control console 2, an electric push rod 4 fixedly connected inside the control console 2, a slider 5 connected to the output end of the electric push rod 4, an adjustment component 6 provided on the upper surface of the slider 5, the outer wall of the slider 5 slidably connected to the inside of the fixed plate 1, a threading needle 9 provided inside the adjustment component 6, a connecting plate 7 slidably connected to the outer wall of the threading needle 9, a screw 8 threadedly connected inside the connecting plate 7, the outer wall of the screw 8 threadedly connected to the inside of the threading needle 9, and the lower surface of the adjustment component 6 fixedly connected to the upper surface of the fixed plate 1.

[0025] Specifically, a rectangular groove is provided in the fixed plate 1. Pressing the first button 3 on the control panel 2 controls the electric push rod 4 to push the slider 5 to slide. The slider 5 pushes the adjustment component 6 to adjust the threading needle 9, thereby flexibly adjusting the needle spacing, achieving precise control of needle density, improving production efficiency, enhancing equipment applicability and reducing costs. The slide rod 603, threading needle 9 and connecting plate 7 are fixed by screws 8.

[0026] Reference Figures 1-2 The adjusting component 6 includes a positioning plate 601, the lower surface of which is fixedly connected to the upper surface of the slider 5. A sliding column 602 is slidably connected inside the positioning plate 601. A sliding rod 603 is fixedly connected to the lower surface of the sliding column 602. A first slide rail 604 is slidably connected inside the slide rod 603. The lower surface of the first slide rail 604 is fixedly connected to the upper surface of the fixing plate 1. A second slide rail 11 is fixedly connected to the upper surface of the fixing plate 1. A wheel 12 is slidably connected inside the second slide rail 11.

[0027] Specifically, the positioning plate 601 has a groove that allows the sliding column 602 to slide. The positioning plate 601 pushes the sliding column 602 to slide, and the sliding column 602 drives the sliding rod 603 to slide on the outer wall of the first slide rail 604. The sliding rod 603 drives the threading needle 9 to slide, thereby achieving flexible adjustment of the needle spacing, realizing precise control of needle density, improving production efficiency, enhancing equipment applicability, and reducing costs.

[0028] Reference Figures 3-4 A connecting rod 10 is rotatably connected to the outer wall of wheel 12, and the lower surface of the connecting rod 10 is slidably connected to the upper surface of the second slide rail 11; the lower surface of the positioning plate 601 is connected to the upper surface of the connecting rod 10, and a spring 15 is provided inside the connecting rod 10; a lock head 14 is slidably connected inside the connecting rod 10, and the outer wall of the spring 15 is connected to the outer wall of the lock head 14; a locking tooth 13 is engaged with the outer wall of the lock head 14, and the upper surface of the locking tooth 13 is fixedly connected to the lower surface of the positioning plate 601; the outer wall of the locking tooth 13 is slidably connected to the inside of the connecting rod 10, and a second button 16 is fixedly connected to the outer wall of the locking tooth 13, and the outer wall of the second button 16 is slidably connected to the inside of the connecting rod 10;

[0029] Specifically, wheel 12 is composed of a support block and a cylinder. Positioning plate 601 drives connecting rod 10 to slide, and connecting rod 10 drives wheel 12 to slide within second slide rail 11 to support the sliding of positioning plate 601. Pressing second button 16 pushes lock head 14 to slide inside connecting rod 10. Lock head 14 pushes spring 15 to contract, sliding the locking teeth 13 on the lower surface of positioning plate 601 into connecting rod 10. Releasing second button 16 causes spring 15 to release its elasticity and push lock head 14 to lock the locking teeth 13, thereby achieving the effect of efficient adaptation to multi-specification production, precise control of needle punching density, and reduction of operation and maintenance costs between connecting rod 10 and positioning plate 601.

[0030] Working principle: When using this positioning block, the electric push rod 4 is controlled by the first button 3 to push or pull the slider 5 to slide within the fixed plate 1. The slider 5 drives the positioning plate 601 to slide, which in turn drives the connecting rod 10 to slide. Furthermore, the connecting rod 10 drives the wheel 12 to rotate within the second slide rail 11. This causes the positioning plate 601 to drive the sliding column 602 to slide within the positioning plate 601. The sliding column 602 then drives the sliding rod 603 to slide on the outer wall of the first slide rail 604. Finally, the sliding rod 603 drives the threading needle 9 to slide, thereby achieving flexible adjustment of the needle spacing, precise control of needle density, improved production efficiency, enhanced equipment applicability, and reduced costs.

[0031] By pressing the second button 16, the lock head 14 is pushed to slide inside the connecting rod 10, thereby pushing the spring 15 to retract, which in turn releases the lock head 14 from the restriction of the locking tooth 13. Furthermore, the positioning plate 601 can be removed, thereby achieving the effect of efficient adaptation to multi-specification production, precise control of needle punching density, and reduction of operation and maintenance costs between the connecting rod 10 and the positioning plate 601.

[0032] 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.
