DETAILED DESCRIPTION

[0023] Example 1

[0024] like Figure 1-5 As shown, a carbon fiber winding and unwinding stand comprises a bottom plate 1, two support columns 2 are symmetrically arranged on the top of the bottom plate 1, a support shaft seat 3 for supporting a carbon fiber roll 5 is arranged on the top of the support column 2, and a positioning buffer mechanism 4 is arranged on the side of the support column 2 for supporting the placement and positioning of the carbon fiber roll 5;

[0025] The positioning buffer mechanism 4 includes a pushing and telescopic cylinder 41 fixedly mounted on the side of the support column 2, a support plate 42 is fixedly mounted on the output end of the top of the pushing and telescopic cylinder 41, a plurality of buffer support rods 43 are symmetrically arranged on the support plate 42, and a V-shaped guide plate 44 is arranged on the top of the buffer support rod 43. In this embodiment, the number of the buffer support rods 43 is two, and they are symmetrically distributed with the center line of the V-shaped guide plate 44 as a reference, the V-shaped guide plate 44 is coaxial with the side opening direction of the support shaft seat 3, and the center line of the V-shaped guide plate 44 is coaxial with the center line of the support shaft seat 3.

[0026] It should be noted that a fixing plate 45 is fixedly provided on the side of the push-telescopic cylinder 41 , and fixing bolts connected to the support column 2 are penetrated through the fixing plate 45 .

[0027] When in use, the V-shaped guide plate 44 is raised to the top of the support shaft seat 3 by pushing the telescopic cylinder 41, and the V-shaped structure of the V-shaped guide plate 44 is used to accurately guide the rotating shaft of the carbon fiber roll 5, so that it can quickly fall above the support shaft seat 3. At the same time, the buffer support rod 43 arranged between the support plate 42 and the V-shaped guide plate 44 can play a buffering effect when the carbon fiber roll 5 falls. The V-shaped guide plate 44 is lowered to the bottom of the support shaft seat 3 by the recovery of the telescopic cylinder 41, and then the rotating shaft of the carbon fiber roll 5 falls accurately into the support shaft seat 3.

[0028] In addition, after unwinding is completed, the rotating shaft of the carbon fiber roll 5 can be lifted again by raising the V-shaped guide plate 44 again.

[0029] In the preferred embodiment, the buffer support rod 43 includes an outer sleeve 431 fixed on the top of the support plate 42, two limiting slide grooves 432 symmetrically arranged on the inner wall surface of the outer sleeve 431, a buffer spring 433 built into the outer sleeve 431, a telescopic rod 434 telescopically arranged in the outer sleeve 431 and with the top end extending to the outside thereof, and a limiting slider 435 fixed on the outer wall surface of the bottom end of the telescopic rod 434 and slidably connected to the limiting slide groove 432. The top end of the telescopic rod 434 is fixedly connected to the V-shaped guide plate 44, and the outer sleeve 431 is a hollow structure with an open top. Through the expansion and contraction of the buffer spring 433, the impact force of the carbon fiber roll 5 when it falls can be reduced.

[0030] Example 2

[0031] Further illustrate with reference to Example 1, Figure 6-7 In the structure shown, the support shaft seat 3 includes a U-shaped seat 31 for supporting the rotating shaft of the carbon fiber roll 5, and extension plates 32 arranged on both sides of the U-shaped seat 31. The extension plates 32 and the U-shaped seat 31 are integrally formed. The extension plates 32 are provided with fixing holes 33 for fixing the support shaft seat 3, so that the fixing bolts can pass through the fixing holes 33 and connect with the support column 2. Limiting components 34 are symmetrically arranged on the relative inner wall surfaces of the U-shaped seat 31 to limit the longitudinal movement of the rotating shaft of the carbon fiber roll 5.

[0032] In the preferred embodiment, the limiting component 34 includes a telescopic cavity 341 opened on the inner wall surface of the U-shaped seat 31, and two symmetrical limiting grooves 342 are arranged on the inner wall surface of the telescopic cavity 341. A tension spring 343 and a limiting block 344 are built in the telescopic cavity 341. One end of the limiting block 344 is in conflict with the tension spring 343, and an anti-slip block 345 slidably connected to the limiting groove 342 is fixed to the outside, and the other end extends to the outside of the telescopic cavity 341, and the upper and lower sides are both arc-shaped and matched with the rotating shaft of the carbon fiber roll 5, so that the tension of the tension spring 343 is used to longitudinally limit the rotating shaft of the carbon fiber roll 5 to avoid unnecessary movement during the unwinding process. At the same time, the arc design makes it easy for the rotating shaft of the carbon fiber roll 5 to use a certain degree of resistance force generated on the limiting block 344 when it falls or lifts, so as to make it telescope, without affecting the normal placement and removal of the carbon fiber roll 5.

[0033] In a preferred embodiment, balls 35 are rotatably provided on the inner bottom wall of the U-shaped seat 31 and the arc at the bottom of the limiting block 344 to reduce the friction of the carbon fiber roll 5 during the unwinding process.

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
