[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] See also Figures 1-4 As shown, the utility model provides a technical solution: a pipe feeding mechanism, including a material rack 1 and a pre-feeding mechanism 3, multiple groups of roller mechanisms 2 are installed on the material rack 1 along the length direction, such as Figure 1 As shown, four groups are preferably provided, and other numbers of groups may be provided as required according to the length of the pipe, and multiple groups of roller mechanisms 2 are arranged equidistantly. Secondly, the roller mechanism 2 includes a movable roller 21, a first adjustable positioning roller 22 and a second adjustable positioning roller 23. The first adjustable positioning roller 22 and the second adjustable positioning roller 23 are located below the movable roller 21, and the spacing between the first adjustable positioning roller 22, the second adjustable positioning roller 23 and the movable roller 21 is adjustable to guide pipes of different diameters. The pre-feeding mechanism 3 is installed on the material rack 1, and the pre-feeding mechanism 3 is used to transport the pipes guided by the roller mechanism 2 along a preset path.

[0028] Among them, see Figure 5As shown, the above-mentioned pre-feeding mechanism 3 includes a feeding cylinder 31 and a clamping and loosening frame 32. The clamping and loosening frame 32 is installed at the output end of the feeding cylinder 31, and a through-hole 33 for the pipe to pass through is provided on the clamping and loosening frame 32. The feeding cylinder 31 is started and the feeding cylinder 31 is used to drive the clamping and loosening frame 32 to extend outward, so that the clamped pipe can be transported to the subsequent processing section.

[0029] Further, see Figure 6 As shown, a mounting groove 321 is provided on the side wall of the through hole 33, and a first bidirectional telescopic rod 322 is installed at the upper end of the inner part of the mounting groove 321. The first bidirectional telescopic rod 322 is an electric or pneumatic telescopic rod. Both ends of the first bidirectional telescopic rod 322 are vertically mounted with a third connecting bar 323, and the bottom end of the third connecting bar 323 is mounted with an arc-shaped clamping plate 324. When transporting pipes to subsequent sections, the two first bidirectional telescopic rods 322 can be retracted to use the two arc-shaped clamping plates 324 to clamp the pipes from both sides, and then the feeding cylinder 31 can be started to extend. After the feeding cylinder 31 reaches the maximum extension length, the first bidirectional telescopic rod 322 can be extended to release the clamping restriction of the arc-shaped clamping plate 324, and then the feeding cylinder 31 is retracted to the initial position, and then the pipe is clamped for transportation. Such a cycle can realize the orderly transportation of longer pipes.

[0030] In addition, see Figure 2 As shown, the roller mechanism 2 also includes a movable arm 24, a connecting shaft 25 and a first connecting bar 27. One end of the movable arm 24 is hinged to the first adjustable positioning roller 22. One end of the connecting shaft 25 and the first connecting bar 27 are both hinged to the movable arm 24. The other end of the first connecting bar 27 is hinged to the second adjustable positioning roller 23. The second adjustable positioning roller 23 is also hinged with a second connecting bar 28. A second two-way telescopic rod 26 is hinged between the second connecting bar 28 and the movable arm 24. The second two-way telescopic rod 26 is an electric or pneumatic telescopic rod.

[0031] Through the above, after the pipe passes through the roller mechanism 2, the pipe is located between the upper movable roller 21 and the lower first adjustable positioning roller 22 and second adjustable positioning roller 23. The guidance of the upper and lower rollers can improve the stability of the pipe during transportation.

[0032] The second bidirectional telescopic rod 26 extends outward, and the movable arm 24, the connecting shaft 25 and the first connecting bar 27 cooperate to move the hinged first adjustable positioning roller 22 and the second adjustable positioning roller 23 upward to reduce the distance between the upper and lower rollers. This is particularly useful for guiding smaller diameter pipes and avoids skewing of the pipes due to excessive spacing.

[0033] Secondly, by retracting the second bidirectional telescopic rod 26, through the cooperation of the movable arm 24, the connecting shaft 25 and the first connecting bar 27, the hinged first adjustable positioning roller 22 and the second adjustable positioning roller 23 can be moved downward to increase the distance between the upper and lower rollers, which is aimed at guiding larger diameter pipes.

[0034] Example 2

[0035] See also Figure 3-Figure 4 As shown, this embodiment is extended on the basis of embodiment 1. Specifically, the movable roller 21 includes a connected upper pressing portion 211 and a fixed blocking portion 212. A movable blocking portion 213 is provided at one end of the upper pressing portion 211 away from the fixed blocking portion 212. The movable blocking portion 213 can approach or move away from the upper pressing portion 211 through a movable structure. The diameters of the fixed blocking portion 212 and the movable blocking portion 213 are both larger than the diameter of the upper pressing portion 211.

[0036] A groove 215 is provided at one end of the upper pressing portion 211 away from the fixed blocking portion 212, and an electric telescopic rod 216 is installed in the groove 215. The outer end of the electric telescopic rod 216 is connected to a connecting column 214, and the outer end of the connecting column 214 is connected to the movable blocking portion 213. The electric telescopic rod 216 and the connecting column 214 in the groove 215 constitute a movable structure.

[0037] Through the above, the upper pressure part 211 at the upper end of the pipe guided by the roller mechanism 2 contacts the upper end surface of the pipe. When guiding pipes of different diameters, the distance between the fixed blocking part 212 and the movable blocking part 213 can be adjusted to restrict the pipe from both sides, thereby reducing the occurrence of skew during the pipe transportation process.

[0038] In the specific adjustment, the distance between the fixed blocking portion 212 and the movable blocking portion 213 can be quickly adjusted by utilizing the extension and retraction of the electric telescopic rod 216 inside the groove 215, which is relatively convenient.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
