[0002] After the pipes cut by a laser pipe cutting machine need to be received and discharged, the existing material receiving rack generally includes a first material receiving plate and a second material receiving plate. The first material receiving plate is also connected to a lifting driving device, and the second material receiving plate is also connected to a flipping driving device. The lifting driving device is used to drive the first material receiving plate and the second material receiving plate to rise synchronously. The flipping driving device is used to make the second material receiving plate horizontal or at a certain inclination angle with respect to the first material receiving plate, so as to support the pipes falling on the first material receiving plate and the second material receiving plate, and enable the pipes to slide and be discharged along the inclined second material receiving plate. This material receiving rack is generally used in cooperation with a chuck type laser cutting machine. When the laser cutting head on the chuck type laser cutting machine cuts the pipes, iron filings are generally generated.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model provides a material receiving rack. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0021] Please refer to Figure 1 and Figure 2, the present utility model provides a material receiving rack, which includes a frame 1, a lifting mechanism 2 arranged on the frame 1, a flipping mechanism 3 fixedly connected to the lifting mechanism 2, a first material receiving plate 4 fixedly connected to the lifting mechanism 2, and a second material receiving plate 5 hinged to the first material receiving plate 4; the lifting mechanism 2 is used to drive the first material receiving plate 4 and the second material receiving plate 5 to rise or fall synchronously; the flipping mechanism 3 is used to drive the second material receiving plate 5 to flip around the hinged position of the first material receiving plate 4 and make the second material receiving plate 5 in a horizontal state or a downward inclined state with respect to the first material receiving plate 4; an outer protection plate 11 is provided around the side wall of the frame 1, and an inner protection plate 12 is arranged on the top of the frame 1. The inner protection plate 12 is located below the first material receiving plate 4 and the second material receiving plate 5, and an avoidance groove is formed on the inner protection plate 12 for avoiding the lifting mechanism 2 and the flipping mechanism 3.

[0022] In practical applications, when it is necessary to support or receive materials of pipes, the lifting mechanism 2 drives the first material receiving plate 4 and the second material receiving plate 5 (at this time, under the action of the flipping mechanism 3, the second material receiving plate 5 is in a horizontal state with respect to the first material receiving plate 4) to rise or fall synchronously, so as to perform follow-up support on the lowest position of the pipes and complete the support of the pipes; when the cutting and material receiving of the pipes are completed, under the action of the flipping mechanism 3, the second material receiving plate 5 is flipped downward around the hinged position of the first material receiving plate 4, and the second material receiving plate 5 is in a downward inclined state, so that the pipes located on the second material receiving plate 5 can slide along the inclined second material receiving plate 5, and finally the blanking of the pipes is completed. The provided outer protection plate 11 and inner protection plate 12 can enclose the inside of the frame 1, that is, the lifting mechanism 2 and the flipping mechanism 3 can be located in the protection cavity surrounded by the outer protection plate 11 and the inner protection plate 12, so as to avoid iron filings generated during the pipe cutting process from falling into the protection cavity and causing damage to the components inside the frame 1.

[0023] Please refer to Figure 1 , in some embodiments, the inner protection plate 12 is arranged to be inclined downward, and the inner protection plate 12 is parallel to the second material receiving plate 5 when the second material receiving plate 5 is in a downward inclined state. The inner protection plate 12 is arranged to be inclined, so that the inner protection plate 12 not only plays a role in preventing iron filings from falling into the inside of the frame 1, but also plays a role in guiding the iron filings falling on the upper surface of the inner protection plate 12, that is, the iron filings on the inner protection plate 12 can slide on the inclined plane, thereby avoiding the accumulation of iron filings on the upper surface of the inner protection plate 12.

[0024] Please refer to Figure 1, in some embodiments, an inclined guide plate 13 is further provided on the frame 1; the inclined guide plate 13 is located in front of the inner protection plate 12, and the inclination angle of the inclined guide plate 13 is the same as that of the inner protection plate 12; a blanking table 14 is further provided below the inclined guide plate 13, and the inclined guide plate 13 is inclined towards the blanking table 14. The iron filings sliding down from the inner protection plate 12 can be collected on the blanking table 14 under the guiding action of the inclined guide plate 13, which can prevent the iron filings accumulated on the inner protection plate 12 from falling into the interior of the frame 1 through the avoidance groove. At the same time, the inclined guide plate 13 can also guide the pipes that roll (for round pipes being cut) / slide (for square pipes / special-shaped pipes / H-beams, etc. being cut) from the second receiving plate 5 to the inclined guide plate 13, so that the pipes can fall more smoothly into the blanking table 14, that is, it plays a buffering role and prevents the pipes from directly falling from the second receiving plate 5 at a relatively high height into the blanking table 14, causing a large impact on the blanking table 14.

[0025] Please refer to Figure 1 , specifically, reinforcing plates 15 are fixedly connected to the lower surfaces of both the inclined guide plate 13 and the blanking table 14. The provided reinforcing plates 15 are used to enhance the connection rigidity between the inclined guide plate 13, the blanking table 14 and the frame 1, and prevent the inclined guide plate 13 and the blanking table 14 from deforming.

[0026] Please refer to Figure 2 , in some embodiments, the lifting mechanism 2 includes a lifting base plate 21 fixedly connected to the lower surface of the first receiving plate 4, a rack 22 vertically arranged on the lifting base plate 21, a bracket 24 fixedly connected to the frame 1, a speed reducer 25 fixedly connected to the bracket 24, a lifting motor 26 connected to the input end of the speed reducer 25, a transmission shaft 27 connected to the output end of the speed reducer 25 through a coupling, and a gear 23 sleeved on the transmission shaft 27; the gear 23 meshes with the rack 22. During the forward or reverse rotation of the lifting motor 26, the transmission shaft 27 and the gear 23 arranged on the transmission shaft 27 rotate forward or reverse, so that the lifting base plate 21 fixedly connected to the rack 22 rises or falls, realizing the follow-up rise or fall of the first receiving plate 4 and the second receiving plate 5.

[0027] Please refer to Figure 2 , in some embodiments, a vertically extending guide rail 28 is provided on the lifting base plate 21, a slider 29 is slidably arranged on the guide rail 28, a first mounting block 30 is fixedly connected to the slider 29, and the first mounting block 30 is fixedly connected to the transmission shaft 27 through a bearing. The provided guide rail 28 and slider 29 are used to enhance the smoothness of the lifting base plate 21 when rising or falling.

[0028] Please refer to Figure 2 andFigure 3 , in some embodiments, a second mounting block 31 is provided on the lifting substrate 21. The flipping mechanism 3 includes a flipping cylinder 32 whose cylinder part is hinged to the second mounting block 31, and a first joint 33 connected to the output end of the flipping cylinder 32; the first joint 33 is fixedly connected to the lower surface of the second material receiving plate 5. The second mounting block 31 provides a mounting position for the flipping cylinder 32. In practical applications, the output end of the flipping cylinder 32 only has a fully extended or fully retracted state. In this embodiment, when the output end of the flipping cylinder 32 is in the fully extended state, the second material receiving plate 5 is in a horizontal state; when the output end of the flipping cylinder 32 is in the fully retracted state, the second material receiving plate 5 is in a downward inclined state.

[0029] Please refer to Figure 1 and Figure 3 , in some embodiments, a waste opening is formed on the second material receiving plate 5. A shaft body is provided on the waste opening, and a waste baffle 51 is rotatably connected to the shaft body. The waste baffle 51 is used to cover the waste opening; a waste cylinder 52 is provided on the lower surface of the second material receiving plate 5. The cylinder part of the waste cylinder 52 is hinged to the lower surface of the second material receiving plate 5, and the output end of the waste cylinder 52 is hinged to the waste baffle 51 through a second joint. Preferably, the waste opening is provided at the left end or the right end of the second material receiving plate 5. When the pipe is cut for the first time or the last time, waste may be generated, and the generated waste can be discharged through the waste opening. In addition, when it is necessary to support and receive the pipe, the output end of the waste cylinder 52 extends to make the waste baffle 51 cover the waste opening; when it is necessary to discharge the generated waste, the output end of the waste cylinder 52 contracts, driving the waste baffle 51 to flip downward, so that the waste on the waste baffle 51 falls from the waste opening.

[0030] Please refer to Figure 1 and Figure 3 , in some embodiments, a waste recycling cart 6 is provided below the waste opening; the waste recycling cart 6 is provided with wheels and a handle. The provided waste recycling cart 6 can recycle the waste falling from the waste opening, and the wheels and the handle can be used to facilitate the regular cleaning of the waste in the waste recycling cart 6.

[0031] Please refer to Figure 1, in some embodiments, a plurality of openings are formed in the second material receiving plate 5, and the openings are arranged in the left-right direction; a rotating roller 53 is rotatably arranged in the corresponding opening, the axis of the rotating roller 53 extends in the front-back direction, the rotating roller 53 protrudes from the corresponding opening, and the rotating roller 53 is used for supporting and guiding the pipe. By providing the openings and the rotating roller 53, the pipe can be slidably supported, avoiding hard friction between the pipe and the second material receiving plate 5 and generating abnormal noises.

[0032] In summary, through the provided outer protection plate 11 and inner protection plate 12, the interior of the frame 1 is enclosed, so that the lifting mechanism 2 and the flipping mechanism 3 are both located in the protection cavity surrounded by the outer protection plate 11 and the inner protection plate 12, thereby preventing iron filings generated during the pipe cutting process from falling into the protection cavity and damaging the components located inside the frame 1.
