Problems solved by technology

[0007] Due to the inconvenient adjustment of the motor speed in the above operations, the collection rod vibrates during rotation, which makes the texture of the artificial blood vessels collected on the collection rod uneven. In addition, the motor is not insulated from the collection rod, and the material ejected from the electrostatic nozzle is easily damaged by static electricity. Attached to the motor, so that the operation fails, and the high-voltage static electricity generated can easily break down the motor

Embodiment Construction

[0024] Such as Figure 4-5 As shown, the structure of the collection rod unit in the artificial blood vessel forming machine of the present invention includes a collection rod 40 whose end is rotated by a motor. The other end of the collecting rod 40 is provided with a supporting unit in a floating connection manner. Specifically, the support unit includes a floating bearing arranged in the floating bearing seat 1, and a push rod supported by the floating bearing, and a spring support unit is provided at the rear end of the push rod.

[0025] In addition, as shown in the figure, the collecting rod 40 passes through an insulating shield 23 and is connected to the clamp at the output shaft end of the motor. In a preferred mode, the motor is a speed-regulating motor, and is equipped with a speed detection and display device. In addition, the base of the collecting rod unit is provided with a height adjustment assembly.

Abstract

The invention discloses an artificial blood vessel forming machine which comprises a collecting rod 40. One end of the collecting rod 40 is driven to rotate by a motor. The other end of the collecting rod 40 is provided with a supporting unit in a floating-connecting mode. According to the artificial blood vessel forming machine, a front end support is used for well solving the problem of collecting rod vibration, and the problem that finished product rate is low is well solved. In addition, an insulation structure of a motor and the collecting rod is improved, motor damage is avoided, and the quality of an artificial blood vessel is further improved. Qualified artificial blood vessels can be manufactured through the artificial blood vessel forming machine, operation is easy, the specifications of the artificial blood vessels can be changed freely, and pass percent can reach more than 95%.

Description

technical field [0001] The present invention relates to an artificial blood vessel forming machine, and more particularly relates to the structural improvement of the collecting rod unit in the artificial blood vessel forming machine. Background technique [0002] With the continuous development of medical science, in clinical medicine, a large number of artificial blood vessels are needed to rescue critically ill patients. During the manufacture of artificial blood vessels, it was found that the texture of the blood vessels produced by the general production method is not uniform, which seriously affects the quality and quality of artificial blood vessels. Life, because the quality cannot be guaranteed, the pass rate of the blood vessels produced is low, which virtually increases the cost of artificial blood vessels. In view of this, in order to improve the quality of artificial blood vessels, reduce the cost of artificial blood vessels. The structure of the collecting rod ...
