Description

Technical Field

[0001] The utility model relates to the technical field of acupuncture equipment, and more specifically, to a driving mechanism of acupuncture machine. Background Art

[0002] A needling machine uses needles to penetrate a web. The barbs on the needles drive the fibers on the web's surface and subsurface, moving them from the web's plane toward the vertical direction, causing the fibers to shift vertically. This upward and downward displacement of the fibers compresses the web, bringing the fibers closer together and compressing them. This requires the needles to move up and down frequently. Existing needling machines often use a crankshaft mechanism to drive this movement, resulting in significant impact and shortening the machine's service life. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See Figures 1 to 3 A drive mechanism for a needling machine includes a frame 100, a mounting cavity 110 disposed within the frame 100, a needling plate 200 disposed below the frame 100, and needles 210 mounted at the bottom of the needling plate 200. A telescopic rod 220 is connected to the needling plate 200, a mounting hole 101 is disposed at the bottom of the frame 100, and the telescopic rod 220 extends through the mounting hole 101 and into the mounting cavity 110. A support plate 120 capable of moving in the vertical direction is installed inside the installation, and the support plate 120 is connected to the telescopic rod 220. The other side of the support plate 120 opposite to the one connected to the telescopic rod 220 is connected to a connecting rod 114, and the connecting rod 114 is connected to the crankshaft 113, and the crankshaft 113 is connected to the main shaft 112. At the same time, a motor 111 is installed on the frame 100, and the output shaft of the motor 111 is connected to the main shaft 112, so that the motor 111 can drive the rotation of the Zhuhai walkway and drive the crankshaft 113 to rotate. The rotation of the crankshaft 113 can drive the connecting rod 114 to move back and forth, thereby driving the support plate 120 to move back and forth in the vertical direction. At the same time, the support plate 120 can drive the telescopic rod 220 and the acupuncture plate 200 to move back and forth in the vertical direction, so that the needle 210 can perform acupuncture operations.

[0020] A guide groove 130 is provided on the side wall of the mounting cavity 110, and a guide block 150 is provided on the support plate 120, which is embedded in the guide groove 130 to maintain the directional stability of the support plate 120 when it reciprocates in the vertical direction. A guide rod 140 is provided in the guide groove 130. The guide groove 130 includes a top surface 131 and a bottom surface 132. The two ends of the guide rod 140 respectively connect the top surface 131 and the ground. A guide hole 151 is provided in the guide block 150. When the support plate 120 reciprocates in the vertical direction, the guide block 150 reciprocates along the guide rod 140. A first spring 133 is sleeved on the guide rod 140. One end of the first spring 133 contacts the bottom surface 132, and the other end of the first spring 133 contacts the guide block 150. When the support plate 120 moves downward, the first spring 133 can buffer the pressure generated by the downward movement, thereby ensuring the service life of the equipment.

[0021] The bottom of the frame 100 is provided with a sleeve 230 extending from the mounting hole 101 toward the interior of the mounting cavity 110. The sleeve 230 surrounds the telescopic rod 220, thereby guiding the movement of the telescopic rod 220. Ball bearings 241 are also provided on the inner wall of the sleeve 230. The balls 241 contact the telescopic rod 220, thereby replacing the sliding friction between the outer wall of the telescopic rod 220 and the inner wall of the sleeve 230 with rolling friction between the telescopic rod 220 and the balls 241. This significantly reduces resistance during movement and thus ensures the service life of the telescopic rod 220.

[0022] Specifically, a mounting groove 231 is defined on the inner wall of the sleeve 230. A support seat 240 is embedded in the opening of the mounting groove 231, and a ball bearing 241 is mounted within the support seat 240. A second spring 232 is disposed within the mounting groove 231. The two ends of the second spring 232 contact the bottom surface 132 of the mounting groove 231 and the bottom surface 132 of the support seat 240, respectively. The second spring 232 pushes the support seat 240 and the ball bearing 241 toward the telescopic rod 220, thereby maintaining contact with the telescopic rod 220. When the ball bearing 241 wears, the spring pushes the support seat 240 further, compensating for the wear and ensuring that the ball bearing 241 maintains contact with the telescopic rod 220.

[0023] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
