Description

Technical Field

[0001] The utility model belongs to the technical field of acupuncture machines, and in particular relates to acupuncture machines for special-shaped fabrics. Background Art

[0002] During needle punching, due to the looseness between fabric layers, the needle cannot introduce enough Z-direction fibers during penetration. As a result, the final fabric density does not meet the design requirements due to insufficient interlayer density. Therefore, it is necessary to compact the fabric during needling to reach the designed thickness before needle punching.

[0003] In the prior art, flat fabrics are needled using a flat needle loom equipped with a stripping plate. The stripping plate is provided with a number of needle holes. When needling the flat fabric, the needle insertion section penetrates the needle holes of the stripping plate and pierces the fabric. At the same time, the stripping plate presses the fabric down to its designed thickness to meet the interlayer density requirements and thus achieve the desired volume density. However, the existing stripping plate has a large contact surface with the fabric, and the Z-direction fibers introduced during needling are limited. Moreover, it cannot be used for fabrics with complex and variable structures. With the exception of rotating shaped fabrics, which can be needled by winding and compacting the fibers, other shaped parts with more complex surfaces can only be compacted manually. However, manual compaction makes it difficult to control the uniformity of the fabric thickness, resulting in the interlayer density and final volume density failing to meet the requirements.

[0017] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention and are not to be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0018] In the present invention, unless otherwise clearly specified and limited, terms such as "installed", "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 and Figure 2As shown, the special-shaped fabric needling machine of this embodiment includes a needling module 1 and a driving module. The driving module is connected to the needling module 1 via a driving rod 9. The driving module is used to drive the needling module 1 to reciprocate. The driving module can be a micro-pneumatic press. The needling module 1 is provided with a through hole, and a pressure rod 2 is movably inserted into the through hole. The pressure rod 2 passes through the top of the through hole and is connected to a limit cap 10. The diameter of the limit cap 10 is larger than the diameter of the through hole. A spring 6 is sleeved on the pressure rod 2. The bottom of the pressure rod 2 is connected to a pressure plate 3. The lower surface of the pressure plate 3 is provided with a plurality of protrusions. The pressure plate 3 is provided with a needle hole 4. A balancing module 7 is provided below the needling module 1. The balancing module 7 is connected to the needling module 1 and contacts the upper end of the spring 6. The balancing module 7 is equipped with needles 5. The needles 5 are arranged in a one-to-one correspondence with the needle holes 4. The number of needles 5 can be adjusted according to the needling process.

[0021] Balancing module 7 is connected to needling module 1 via screw 8. The distance between balancing module 7 and needling module 1 is adjustable. Screw 8 is threadedly connected to balancing module 7 and screw 8 is also threadedly connected to needling module 1. Before the special-shaped fabric needling machine is put into operation, the distance between balancing module 7 and needling module 1 can be determined according to actual needs, and screw 8 can be tightened. By adjusting the distance between balancing module 7 and needling module 1, the deformation of spring 6 can be adjusted to further control the needling force and depth.

[0022] The number of pressure rods 2 is adjusted according to the shape of the pressing plate 3. When the pressing plate 3 is rectangular, two pressure rods 2 are provided. When the pressing plate 3 is L-shaped or triangular, three pressure rods 2 are provided. When the pressing plate 3 is circular or square, four pressure rods 2 are provided. The length of the pressure rods 2 can be configured to be all the same length or to have different lengths depending on the acupuncture angle.

[0023] The convex point design on the lower surface of the pressing plate 3 can greatly reduce the contact area with the fabric, introduce more Z-direction fibers during the needling operation, and improve the interlayer strength.

[0024] The special-shaped fabric needling machine of this embodiment can not only realize the compaction operation of the fabric thickness, but also adjust the needling angle. Moreover, due to the convex point design of the pressing plate 3, the contact surface with the fabric is greatly reduced, so that more Z-direction fibers are introduced during the needling operation of the needling module 1, thereby improving the interlayer strength.

[0025] The present invention is not limited to the above-mentioned optional implementation methods. Anyone can derive various other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention shall fall within the scope of protection of the present invention.
