It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0017] ​In order to illustrate the technical scheme of the utility model, the following will be explained by specific embodiments.

[0018] For the convenience of illustration, only the parts related to the embodiments of the utility model are shown.

[0019] Combined Figures 1-4 As shown in the figure, the metal product feeding device comprises a processing table 1 and a rack 2 arranged side by side, the bottom plate 3 of the rack 2 is arranged obliquely towards the front and downwards, the front end of the rack 2 is provided with a pair of fixed rods, the upper fixed rod 41 is fixedly installed, and the lower fixed rod 42 is fixedly installed, the lower fixed rod 42 is located below the bottom plate 3, a pair of chain wheels 5 are arranged on the fixed rods, the lower chain wheel 5 is fixedly installed, and the upper chain wheel 5 is rotatably installed, a chain 6 is sleeved between the upper and lower chain wheels 5 on the same side, a ring of L-shaped loading blocks 7 is arranged on the chain 6, a driving motor 8 for driving the lower fixed rod 42 to rotate is arranged in the rack 2, a feeding mechanism is arranged on the processing table 1, the feeding mechanism comprises a pair of left and right feeding seats 9, the inner wall of the feeding seat is provided with a feeding plate 10, the feeding plate 10 is arranged obliquely towards the front and downwards, a limiting plate 11 is arranged above each feeding plate 10, a feeding channel is formed between the limiting plate 11 and the feeding plate 10, a material blocking cylinder 12 is arranged on the processing table 1 at the tail of the feeding plate 10, and a blocking plate 13 is arranged on the driving shaft of the material blocking cylinder 12.

[0020] The metal tubular material is a common processing material, and the tubular metal product can be fed by using the device in the processing process. In the embodiment, the processing table is provided with a processing mechanism for processing the metal product. When the tubular metal product is sequentially and one by one sent to the processing mechanism for processing by using the device, a certain number of metal products with the same specification are placed in the rack according to the requirements, then the driving motor drives the lower fixed rod to rotate, the two lower chain wheels rotate synchronously, then the two chains rotate upwards in the opposite direction, since a ring of loading blocks is uniformly arranged on each chain, when the current two loading blocks on the same layer rotate to the bottom of the bottom plate, the metal product at the bottom of the bottom plate is rolled onto the current two loading blocks and moves upwards along with the loading blocks. When the loading blocks rotate to the top, the metal product on the loading blocks falls onto the feeding mechanism. In the above structure, the metal product in the rack can be accurately and effectively sent to the feeding mechanism by the chain conveying mode.

[0021] As a preferred structure, as shown in the figure, Figure 3 The tail of the feeding plate 10 in the feeding channel is provided with a blocking block 14, the upper side of the blocking block 14 is provided with an upper blocking plate 15, a circular hole is formed in the rear side of the feeding plate 10 at the blocking block 14, a push cylinder 17 is arranged on the bottom surface of the feeding plate 10, a push block 18 is arranged on the driving shaft of the push cylinder 17, and the push block 18 is located in the circular hole.

[0022] In the structure, the limiting plates on the same side form the feeding channels between the feeding plates. When the two load blocks on the same layer rotate to the top, the two ends of the metal products on them drop into the two feeding channels at the same time, and the metal products slide forward in the feeding channels to the waiting positions, i.e. the stop blocks stop the metal products. When the previous metal product is finished processing, the two push cylinders drive the push blocks to move upward at the same time, the push blocks push the metal products a small distance upward, and after the metal products are higher than the stop blocks, the metal products are stopped by the stop plates after passing the stop blocks. At this time, the metal products are in the processing position and wait to be processed by the processing mechanism.

[0023] In the above structure, the tail of the upper stop plate 15 is provided with a rear upward guide groove 16, so that the entrance of the feeding channel is widened, and under the guidance of the guide groove, each metal product can smoothly enter the feeding channel. In addition, under the limiting of the metal product, when the push block pushes the metal product a small distance upward, the metal product can successfully pass the stop block and move to the processing position.

[0024] In the device, as Figure 2 , a pair of intermediate rods 19 are arranged between the two fixed rods on the rack 2, and a pair of stop plates 20 are arranged on the intermediate rods 19 and face the chain 6. In actual process, the stop plates limit the chain, and under the action of the stop plates, the metal products on the two load blocks on the same layer can be stably sent to the feeding mechanism.

[0025] Further, as a preferred structure, as Figure 1 , a pair of adjusting seats 21 are arranged on the rack 2, adjusting grooves 22 are arranged in the adjusting seats 21, the two ends of the upper fixed rods 41 are arranged in the adjusting grooves 22 on the same side, and adjusting screws 23 are screwed into the top of the adjusting seats 21, and the bottom of the adjusting screws 23 is connected with the upper fixed rods 41.

[0026] In the above structure, the tightness of the two chains can be adjusted by fine-tuning the position of the upper fixed rods. When the position of the upper fixed rods needs to be adjusted, only the two adjusting screws need to be screwed, and the two ends of the upper fixed rods move in the corresponding adjusting grooves during the screwing process, so as to adjust the tightness of the chains.

[0027] In addition, as Figures 1-2The material rack 2 is provided with two baffle plates 24, one on the left and one on the right. The left baffle plate is fixedly installed and the right baffle plate is slidably installed. A guide frame 25 is inserted into the right side of the material rack 2 and is connected to the right baffle plate. A locking sleeve 26 is provided on the right side of the material rack 2. A locking rod 27 is provided inward on the guide frame 25. The end of the locking rod 27 passes through the locking sleeve 26 and is connected to the right baffle plate. A threaded hole 32 is opened on the locking sleeve 26, and a locking nut (not shown in the figure) is screwed into the threaded hole 32 to resist the locking rod.

[0028] The material rack is equipped with two baffles, one on the left and one on the right, which together form a feeding zone. A certain number of metal products are placed into the feeding zone. The length of the feeding zone matches the length of the metal products, and the size of the feeding zone can be adjusted by adjusting the position of the right baffle to accommodate metal products of different lengths.

[0029] To adjust the position of the right baffle, simply unscrew the locking nut, then push the guide frame left and right; the right baffle will move accordingly. Once the right baffle is in position, screw the locking nut into the threaded hole until the bottom of the locking nut abuts against the locking rod; at this point, the guide frame is positioned.

[0030] In this device, the upper left feed seat 9 is fixedly installed, and the upper right feed seat is slidably installed on the processing table 1 via a slide rail 28. A lead screw 29 is rotatably mounted on the processing table 1, with a handle 30 at the tail of the lead screw 29. A lead screw sleeve 31 is mounted on the upper right feed seat 9, and the sleeve 31 is located on the lead screw 29. After the right baffle plate is adjusted, the position of the upper right feed seat needs to be adjusted accordingly to accommodate metal products of different lengths. Specifically, this is achieved by rotating the handle to rotate the lead screw, which in turn moves the upper right feed seat left and right to adapt to the position of the right baffle plate.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
