[0031] The working principle of the embodiment is as follows:

[0032] The titanium wire feeding device of the utility model can keep the titanium wire stable during feeding, avoid the titanium wire from deviating, and have better stability.

[0033] The beneficial effects of the embodiment are as follows:

This arrangement can also limit the titanium wire, but the friction force is too large, and the feeding speed is reduced.

[0036] Embodiment Two

[0037] This embodiment is a second embodiment of a titanium wire feeding device with stable feeding. This embodiment is similar to the first embodiment, and the difference is that, as shown in Figure 3 The upper base 200 and the lower base 100 are slidably connected in the vertical direction. In this embodiment, the second locking member 700 is a bolt, the second locking member 700 passes through the bolt hole in the bottom of the upper base 200 and is threadedly connected with the lower base 100, and the elastic member 800 is located between the upper base 200 and the lower base 100.

[0038] The working principle of this embodiment is as follows:

[0039] When the titanium wire is fed, if the friction force between the titanium wire and the upper compression roller 300 and the lower compression roller 400 is too small, slipping is prone to occur. If the distance is too small, the friction force is too large, and the titanium wire cannot be pulled. Since the upper base 200 and the lower base 100 are slidably connected, the distance between the upper compression roller 300 and the lower compression roller 400 can be adjusted to keep the friction force moderate. The upper base 200 and the lower base 100 are threadedly connected through the second locking member 700, so that the distance between the upper base 200 and the lower base 100 can be adjusted by adjusting the second locking member 700.

The upper machine base 200 has an upper oil storage chamber, and the lower machine base 100 has a lower oil storage chamber. The upper machine base 200 and the lower machine base 100 are respectively provided with an upper oil filler 210 and a lower oil filler 110. The upper oil filler 210 is connected to the upper oil storage chamber, and the lower oil filler 110 is connected to the lower oil storage chamber. It also includes an upper dust cover 220 and a lower dust cover 120. The upper dust cover 220 is installed on the upper machine base 200 and is used to cover the upper bearing. The lower dust cover 120 is installed on the lower machine base 100 and is used to cover the lower bearing. The outer surface of the upper pressure roller 300 has an annular groove 310. The outer surface of the lower pressure roller 400 has a plurality of anti-slip protrusions 410 evenly arranged along the circumference. The anti-slip protrusions 410 extend along the axial direction.

[0043] The working principle of this embodiment is as follows:

[0044] Lubricating oil can be injected into the upper oil reservoir through the upper oil filler 210 and into the lower oil reservoir through the lower oil filler 110. The lubricating oil can lubricate the bearing and improve its smoothness. The upper and lower bearing covers can prevent dust from entering the bearing and reducing its smoothness. The titanium wire is located in the annular groove 310, which increases the contact area with the upper pressure roller 300, thereby increasing friction and preventing slippage. The anti-slip protrusion 410 can increase the friction between the lower pressure roller 400 and the titanium wire and prevent slippage.
