A feeding mechanism and a material ejecting mechanism are provided at both ends of the material rack, and the material ejecting mechanism ejects the pipe material in the material feeding trough toward the feeding mechanism, and the feeding mechanism delivers the pipe material in the material feeding trough. During operation, the whole bundle of pipes is hoisted in the storage trough, the guide mechanism lifts the pipes to the upper side of the guide surface, the guide mechanism descends, the pipes are guided by the guide surface and fall into the feeding trough, the push-up mechanism pushes the pipes to the feeding mechanism, and then the feeding mechanism sends the pipes pushed by the push-up mechanism out of the feeding trough. The utility model removes the material belt, avoids the risk of the material belt breaking during the feeding process, realizes single-piece feeding when the sensor and the pressing mechanism are removed, the whole device is simple, reduces the equipment failure rate, reduces the equipment maintenance time, and improves the processing efficiency.

[0007] Furthermore, in the above-mentioned automatic feeding device for pipe materials, the material feeding mechanism includes a material feeding rack, the material feeding rack is close to the side wall of the support plate, the material feeding trough is provided on the upper side of the material feeding rack, and the bottom surface of the material feeding trough is an inclined surface. A first guide rail and a material feeding cylinder are connected to the side of the support plate away from the material feeding rack, the first guide rail is vertically connected to the side wall of the support plate, and the material feeding cylinder and the first guide rail are arranged in parallel. The first guide rail is slidably connected to the first slider, and the support plate is provided with a through groove, and the through groove is vertically arranged on one side of the first guide rail. A first connecting block and a second connecting block are connected to the side of the material feeding rack close to the first guide rail, and the first connecting block passes through the through groove and is connected to the first slider. The second connecting block passes through the through groove and is driven and connected to the cylinder shaft of the material feeding cylinder. During the feeding process, the feed cylinder pushes the feed frame to rise along the first guide rail, and the feed frame lifts the pipe material in the storage trough. When the pipe material leaves the storage trough, it falls into the feed trough. Since the bottom surface of the feed trough is an inclined surface, the pipe material rolls toward the feeding trough, the feed frame descends, and the pipe material contacts the guide surface, and the pipe material falls into the feeding trough under the guidance of the guide surface. The entire feed mechanism has a simple structure, with only one electrical component, the feed cylinder, which reduces the equipment failure rate and improves production efficiency.

The guide surface 113 comprises a first inclined surface 1131 and a second inclined surface 1132, and the first inclined surface 1131 is higher than the second inclined surface 1132 to form a step. A material guiding mechanism 14 is arranged on the lower side of the guide surface 113, and the material guiding mechanism 14 is connected to the side wall of the support plate 11, and the material guiding mechanism 14 guides the pipe material in the material storage trough 111 into the feeding trough 112. A feeding mechanism 2 and a material ejecting mechanism 3 are provided at both ends of the material rack 1.
