Embodiment 1

[0044] Due to the high output and variety of acupuncture needles, it is impractical to manually inspect the fastness of each acupuncture needle. The random inspection method is generally used, but there must be missed inspections in the random inspection method, and there will be acupuncture needles with excessive fastness, which will cause damage to the enterprise. In order to solve this problem, the present invention proposes an automatic drawing machine for testing the fastness of the connection between the needle handle and the needle body, which includes the needle feeding part, and also includes the drawing structure, the storage tank and the driving part, wherein, A cover plate 1 is provided above the conveyor belt 2, and the cover plate 1 is used to block dust or foreign matter, so as to prevent acupuncture needles from jumping out of the groove for some reason, affecting safe production; grooves are uniformly arranged on the conveyor belt 2, and the grooves The length ...

Embodiment 2

[0061]A certain type of acupuncture needle has a handle 3 with a diameter of 1.1 mm and a length of 15 mm; a needle body 4 with a diameter of 0.16 mm and a length of 30 mm, and a standard fastness of 8N. Adopt the drawing machine described in embodiment 1 to check the fastness, wherein, the arc diameter of the groove on the conveyor belt 2 is 2mm, the width of the conveyor belt 2 is 20mm, and the dynamometer used is a digital dynamometer. The device is a single-chip microcomputer, the motor is a speed-regulating motor, and the processor is connected to the touch-screen display, so that the conveyor belt 2 can be directly set on the touch-screen display, and the pressure and speed of each group of upper rollers 5 and lower rollers 6 can be adjusted. The first set of rollers is 7.5N, the second set of rollers is 8N, the third set of rollers is 8N, and the fourth set of rollers is 8.5N. The material of the roller is rubber. During long-term operation, the surface of the roller sh...

Embodiment 3

[0063] A certain type of acupuncture needle has a handle 3 with a diameter of 1.3mm and a length of 15mm; a needle body 4 with a diameter of 0.3mm and a length of 40mm, and a standard fastness of 15N. Adopt the drawing machine described in embodiment 1 to check the fastness, as long as the pressure and speed of each group of upper rollers 5 and lower rollers 6 are adjusted, and the digital tension meter is used to check, the first group of rollers is 14N, and the second group of rollers is 15N. , the third set of rollers is 16N, and the fourth set is 16.5N. All the other parts are the same as in Example 2.

Abstract

The invention discloses an automatic drawing machine for inspecting stem to needle body connection firmness and an application method of the automatic drawing machine and belongs to the technical field of firmness inspection of acupuncture needles. The automatic drawing machine comprises a conveying belt, drawing structures, a storage trough and a drive part. Retaining plates include an upper retaining plate and a lower retaining plate. The plane that the upper retaining plate and the lower retaining plate locate in is parallel to that of the conveying belt. A distance (or gap) between the upper retaining plate and the lower retaining plate is greater than the diameter of a needle body and less than the diameter of a stem. A midpoint of the distance between the upper retaining plate and the lower retaining plate and a direction of the needle body are collinear. Rollers include upper rollers and lower rollers in contact with each other; the drawing structures are evenly distributed on one side of the conveying belt; the drive part comprises a motor and a processor; each group of upper and lower rollers is driven by one motor; the conveying belt is driven by another motor; all the motors are connected with the processor; the storage trough is disposed below the other end of the conveying belt. The automatic drawing machine is capable of inspecting firmness of each acupuncture needle and has an auto-sorting function.

Description

technical field [0001] The invention relates to the technical field of acupuncture needle fastness inspection, in particular to a method for using an automatic drawing machine for inspecting the connection fastness of a needle handle and a needle body. Background technique [0002] In the production process of Chinese medicine acupuncture needle industry, semi-finished products or finished products must be inspected for the connection fastness between the needle body and the needle handle, and the inspection methods are all manual pulling methods. It is to clamp the handle of a needle on a tube spring scale with scale, and use the clamp to clamp the needle body and pull it down. Assuming that the pointer of the spring scale passes through the scale of 5 Newton, the needle body and the needle handle will separate. The connection fastness of this acupuncture needle is 5 Newtons. If the assessment index is 10 Newtons, then this acupuncture needle is determined as a substandard ...
