[0002] Laser tube cutting machines have the advantages of high precision, high cutting efficiency, neat incisions and low production costs, so they have been widely used; however, the laser tube cutting machines currently on the market are mainly single-tube cutting machines, or laser tube cutting machines with single-sided loading systems. This loading system is basically set on one side of the laser tube cutting machine for loading. The basic single-sided loading system can only use multiple chains to move the tubes to one side of the laser tube cutting machine, causing the tubes to pile up in a disorderly manner at the loading port of the laser tube cutting machine. Manual sorting of the accumulated tubes is required. At the same time, when the heights of multiple chains deviate, when the chains drive the tubes to move, a large number of accumulated tubes will appear to be offset left and right.

[0008] Furthermore, the elastic push piece includes a support plate and an extension end fixedly connected to the support plate. A spring located below the support plate is provided at the bottom of the accommodating groove. The extension end is located in a sliding groove opened on both sides of the fixing mechanism, and the extension end can slide vertically along the sliding groove.

[0009] Furthermore, a corresponding rectangular lining plate is provided at the upper end of the slideway, a hydraulic rod is provided at the bottom of the lining plate, and the telescopic end of the hydraulic rod faces the upper surface of the extension end.

[0010] Furthermore, elastic pieces are symmetrically arranged at the upper opening of the accommodating slot.

[0011] Furthermore, a cylinder is provided at one end of the push block, and a telescopic rod of the cylinder is fixedly connected to the push block.

[0012] Furthermore, the vertical distance between two opposite groove walls of the accommodating groove is smaller than the sum of the outer diameters of the two pipes placed in the accommodating groove.

[0013] The technical effects and advantages of this utility model are:

[0014] The utility model places the pipe into the accommodating groove through the upper opening of the accommodating groove, that is, the feeding port, and arranges the pipes in an orderly staggered manner. Then, the arranged ejecting mechanism ejects the staggered pipes one by one, thereby avoiding disorderly accumulation of the pipes and the need for manual sorting during feeding.

[0024] The solution of this embodiment provides an automatic feeding device for a laser tube cutting machine, including a fixing mechanism 100 and a lifting mechanism 200, the fixing mechanism 100 has a receiving groove 107 with an upper opening, the upper end opening of the receiving groove 107 is inclined and close to the middle, and an elastic member 4 is symmetrically arranged at the upper end opening of the receiving groove 107, the elastic member 4 is used to fix the tube 3 in the receiving groove 107, and the tubes 3 are neatly staggered in the receiving groove 107, the upper opening of the receiving groove 107 forms a feed port 104 through the elastic member 4, and the size of the feed port is slightly larger than the diameter of a tube, so that not only does not affect the discharge of the tube, but also can fix the tube 3 and prevent the tube from running out of the feed port, the bottom of the receiving groove 107 is provided with a support plate 103 for squeezing and fixing the tube 3, and the support plate 103 is used to hold the entire tube 3 placed in the groove The material 3 is fixed by the pressure provided by the elastic member 4; the pushing mechanism 200 is arranged at one end of the accommodating slot 107, and the upper part of the pushing mechanism 200 is provided with a slide 205 connected to the opening of the accommodating slot 107, and the slide 205 is fixed by two symmetrical guard plates 201. A push block 202 is provided in the slide 205, which slides horizontally along the slide 205, and a push block 2021 is provided at the lower part of the push block 202 for pushing the pipe 3. The sliding of the push block 202 drives the push block 2021 to push the uppermost pipe 3 in the accommodating slot 107, pushes the uppermost pipe 3 out, and then places it on the laser pipe cutting machine for cutting. It should be noted that a pusher for pushing the pipe 3 into the pipe cutting machine is also provided between the fixing mechanism 100 and the pipe cutting machine. The pusher is a simple combination of a cylinder and a push plate. This structure is a prior art and will not be repeated here.

[0025] It should be further explained that the support plate 103 includes an extension end 1031 fixedly connected to the support plate 103 , and at least two springs 105 are provided at the lower portion of the support plate 103 . The extension end 1031 moves radially along the slide grooves 106 provided on both sides of the fixing mechanism 100 . During use, the springs 105 and the support plate 103 cooperate to push the pipe 3 placed on the upper portion upward, thereby always keeping the pipe 3 at the top. Specifically during use.

[0026] It should be further explained that a corresponding rectangular lining plate 101 is provided at the upper end of the slide 106, and a hydraulic rod 102 is provided at the bottom of the lining plate 101. The telescopic end of the hydraulic rod 102 faces the upper surface of the extension end 1031. When in use, the hydraulic rod 102 is pressed against the extension end 1031 and moves downward to facilitate the entry of the pipe. When the pipe 3 is filled in the accommodating groove, the hydraulic rod 102 contracts and resets, leaving the active stroke of the extension end 1031 to facilitate up and down movement.

The length of the push block 202 is equal to the radius of the top pipe 3 in the accommodating groove 107, so as to prevent the push block 202 from pushing out multiple pipes 3 at one time.

[0028] It should be further explained that the distance between the two plate walls of the fixing mechanism 100 is smaller than the sum of the diameters of the two pipes 3, which facilitates the staggered placement of the pipes 3. It should be explained that the distance between the two plate walls for fixing the pipes 3 is set according to the actual diameter of the pipes 3.

[0029] Working principle of this utility model:

[0030] During use, the pipe 3 is placed into the receiving groove through the upper opening of the receiving groove, that is, the feed port 104. The pipes 3 are arranged neatly and staggered, and then the staggered pipes 3 are ejected one by one by the ejecting mechanism 200, thereby avoiding the disorderly accumulation of the pipes 3 and avoiding the need for manual sorting during feeding.

[0031] At the same time, an elastic member 4 is provided at the upper opening to assist in the loading and fixing of the tube 3, so as to ensure that the tube 3 can be smoothly and stably supplied to the laser tube cutting mechanism during the loading process. The elastic member 4 can firmly clamp multiple tubes 3 together through its elasticity and tension to form a whole. The elastic member 4 can provide a certain amount of assistance, so that the tube 3 can enter the accommodating groove more smoothly.
