Problems solved by technology

Since the medical catheters are all soft rubber hoses, the catheters wound on the tray must be bent to a certain extent after being pulled out. The fixing mechanism and the positioning mechanism do not straighten and tension the catheters after they are clamped, and the cutter assembly In the process of moving the pipe upwards, the pipe will not be cut until

Abstract

The invention provides a catheter feeding device of a puncture needle assembling machine, and belongs to the technical field of medical equipment. According to the device, the problem of poor stability of existing catheter cutting is solved. The catheter feeding device of the puncture needle assembling machine comprises a catheter unwinding mechanism, a catheter taking mechanism and a catheter feeding mechanism, wherein the catheter taking mechanism comprises a base, a positioning assembly, a positioning clamping finger and a cutter assembly, the catheter unwinding mechanism comprises an unwinding support, the catheter feeding mechanism comprises a feeding clamping finger, the catheter taking mechanism further comprises a material taking clamping finger and a cutter buffering block which are arranged on the base in a sliding mode, the feeding clamping finger is located above the end, provided with the material taking clamping finger, of the base and is close to the cutter assembly, theopposite ends of the unwinding support and the base are provided with limiting rolling wheel assemblies, the two limiting rolling wheel assemblies are arranged at the same height and staggered, and the positioning assembly comprises a vertical plate and a catheter inlet guide block which is arranged on the vertical plate and is penetrated through by a catheter. According to the device, cutting stability and cutting precision of the catheter are improved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a puncture needle assembly machine, in particular to a catheter feeding device of the puncture needle assembly machine. Background technique [0002] The puncture needle assembly machine is a mechanical device for producing and assembling puncture needles. It mainly includes an organism. There are multiple puncture needle assembly stations on the body. The puncture needles need to be assembled sequentially along the multiple assembly stations to complete the overall assembly. . The puncture needle includes a catheter. When assembling, after the assembly of the steel needle assembly and the butterfly wing is completed, the assembly of the steel needle assembly and the butterfly wing is installed on one end of the catheter. Therefore, the puncture needle assembly machine includes a catheter feeding mechanism and The catheter feeding mechanism will feed the catheter feeding...
