[0032] Working principle and use process of the present invention: After the present invention is installed, the cloth is placed on the needling bottom plate 12 (the cloth is moved via the front and rear conveying equipment), and then when powered on, the motor drives the belt drive wheel 2, and then under the active support of the reducer 3 and the left bearing seat 4 and the right bearing seat 8, the kinetic energy is transmitted to the cam 18 for eccentric rotation, and during the eccentric rotation, the intermittent contact between the cam 18 and the kinetic energy reversing shaft 19 (the kinetic energy reversing shaft 19 is movably inserted into the positioning shaft tube 14) is used to guide the needling positioning plate 13 to move up and down reciprocatingly (the needling positioning plate 13 is suspended and supported by the elastic support assembly 15). The process of reciprocating up and down movement is the process of needling the cloth above the needling bottom plate 12 by the needling plate 16 (and after needling, the material is loaded and unloaded through the front and rear conveying equipment). In order to avoid the deformation problem of the main shaft 6 caused by the transmission needling positioning plate 13 being suspended on the main shaft 6 through the connecting rod during use, A new elastic support component 15 is adopted, which includes eight structures including a rod top groove 151, a spring 152, an anti-slip disk 153, a disk groove 154, a fixed disk 155, a sleeve 156, an externally threaded rod 157 and a rod 158. When the eight structures are used in combination, when the rod 158 is inserted into the sleeve 156, the anti-slip disk 153 at the upper end of the spring 152 is limited to the disk groove 154 set in the fixed disk 155, and The external threaded rod 157 at the lower end of the spring 152 is bolted to the top groove 151 of the insertion rod set at the top of the insertion rod 158 to achieve elastic support for the acupuncture positioning plate 13. The elastic support can provide force buffering when the kinetic energy reversing shaft 19 moves downward, and at the same time provide upward recovery force for the acupuncture positioning plate 13 when the kinetic energy reversing shaft 19 is not subjected to force. This setting can greatly reduce the lifting force of the transmission main shaft 6, and can avoid acupuncture errors caused by main shaft deformation during long-term use.
