DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] For example, see Figures 1 - 4 The utility model provides a technical solution: a material unloading rack, which comprises: a rotating shaft 1.

[0024] Specifically, a turntable 2 is fixedly connected to both ends of the rotating shaft 1, and the rotating shaft 1 is rotatably mounted on an external stand (not shown in the figure). A material placement groove 21 is penetrated and opened at the surface edge of the turntable 2, and the material placement grooves 21 on the two turntables 2 are kept in one-to-one correspondence. When the pipe cutting is completed, the pipe will automatically fall into the material placement groove 21 under the action of gravity. At this time, the two turntables 2 can support the two ends of the pipe respectively, and the rotation of the turntable 2 can drive the pipe to move accordingly. The outer side between the two turntables 2 is covered with a side baffle 3, and the side baffle 3 is set to an arc structure concentric with the turntable 2, and the open end face of the side baffle 3 is inclined. The setting of the side baffle 3 is used to prevent the turntable 2 from causing the pipe in the inner cavity of the material placement groove 21 to fall during the rotation process. Figure 2 As shown, when the turntable 2 rotates counterclockwise at an angle between 180 and 270 degrees, the pipe can be separated from the inner cavity of the material trough 21 from the lower right side of the rotating shaft 1 under the action of gravity;

[0025] Secondly, a push block 4 driven by a cylinder 5 is arranged outside one end of the side baffle 3, and a gap is left between the push block 4 and the turntable 2. When the turntable 2 is conveying the pipeline, the push block 4 will not collide with the end of the pipeline. Figure 1 and Figure 2As shown, when the turntable 2 rotates counterclockwise to drive the pipeline to move to the upper left corner position of the rotating shaft 1, the end face of the pipeline corresponds to the push block 4. At this time, the air cylinder 5 extends by a certain amount: if the pipeline is a short pipeline, the push block 4 does not contact the pipeline; if the pipeline is a long pipeline, the push block 4 contacts the end face of the pipeline and pushes the pipeline to move a certain distance. Further, a conveying rack 7 is arranged outside the other end of the side baffle 3. The conveying rack 7 corresponds to the push block 4. A conveying roller 71 is rotatably installed on the conveying rack 7. The middle part of the surface of the conveying roller 71 is recessed inward to form an annular groove. When the push block 4 pushes the long pipeline to move from one end of the long pipeline, the other end of the long pipeline can fall onto the conveying rack 7, and the conveying roller 71 is used to convey the long pipeline until the long pipeline completely separates from the two material placing grooves 21, so as to realize the separation of long and short pipelines.

[0026] To facilitate the conveying of the long pipeline, the conveying rack 7 of the present application is horizontally arranged. A plurality of conveying rollers 71 are arranged and are equidistantly distributed along the length direction of the conveying rack 7. A rubber pad is bonded in the annular groove of the conveying roller 71. The rubber pad is provided to increase the friction between the conveying rack 7 and the long pipeline, so as to facilitate the conveying of the long pipeline.

[0027] To drive the rotation of the conveying roller 71, the present application also has a sprocket 73 fixedly connected to one end of the rotating shaft of the conveying roller 71. A plurality of sprockets 73 are kept in driving connection through a transmission chain 74. A driving motor 72 for driving the conveying roller 71 to rotate is installed on the side of the conveying rack 7. As Figure 4 shown, a plurality of conveying rollers 71 can rotate synchronously and in the same direction, so as to improve the conveying efficiency of the long pipeline.

[0028] To install the side baffle 3 and the air cylinder 5, the present application also has mounting frames 31 fixedly connected to both ends of the side baffle 3. The mounting frames 31 are movably sleeved on the outer side of the end of the rotating shaft 1. The mounting frames 31 are fixedly connected to an external vertical frame (not shown in the figure) to prevent the side baffle 3 from shifting in position. The air cylinder 5 is fixedly connected to one mounting frame 31 through a bracket 6. The position of the air cylinder 5 itself is fixed. When the air cylinder 5 extends, it can push the push block 4 to move.

[0029] To keep one end face of the pipeline flush, the present application also has a vertical plate 8 fixedly installed at the upper end of the other mounting frame 31. The vertical plate 8 is located directly below the cutting blade 9. A magnet sheet 81 is fixedly installed on the side surface of the vertical plate 8 away from the side baffle 3. Combining Figure 1 and Figure 4 it can be known that after the cutting blade 9 cuts the pipeline, the dropped pipeline just lies on the other side of the vertical plate 8. At this time, the magnet sheet 81 can provide a certain attraction force to the metal pipeline to ensure that each pipeline falling into the material placing groove 21 can keep one end face flush (i.e., fitting against the vertical plate 8).

[0030] To prevent the long pipeline from tilting during movement, multiple material placement grooves 21 of the present application are provided and distributed in an annular array around the rotating shaft 1, which can improve the feeding and conveying efficiency after the pipeline is cut. A support plate 22 corresponding to each of the multiple material placement grooves 21 is arranged on the outer side of the rotating shaft 1, and both ends of the support plate 22 are fixedly connected to two turntables 2 respectively. The support plate 22 is mainly used to prevent the long pipeline from tilting when it is pushed horizontally by the push block 4. A smooth layer 23 is arranged on the inner wall of the support plate 22 to reduce the friction between the long pipeline and the inner wall of the support plate 22, ensure that the push block 4 can easily push the long pipeline to move, and after the long pipeline is separated from the push block 4, the long pipeline can slide a certain distance under the action of inertia.

[0031] The present application also discloses a pipe cutting machine, including the above-mentioned blanking rack.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
