[0040] The present invention provides a feeding device for pipe sandblasting, such as Figure 1 , Figure 5 and Figure 8As shown, it includes a workbench 1; and a storage bin 2 is arranged on the workbench 1 and located at one end of the workbench 1, for placing a large number of pipe fittings and discharging the pipe fittings; a distribution structure 3 is arranged on the storage bin 2, for distributing and conveying the pipe fittings; a conveying structure 4 is arranged on the workbench 1 and located at one side of the distribution structure 3, for conveying the pipe fittings; a moving structure 5 is arranged on the workbench 1 and located at the lower surface of the workbench 1, for driving the workbench 1 to move; the storage bin 2 includes a bin body shell 21 and a partition plate 22, the bin body shell 21 is arranged on the workbench 1, the partition plate 22 is arranged inside the bin body shell 21, the partition plate 22 divides the inside of the bin body shell 21 into a first channel 23 and a second channel 24, and the partition plate 22 is fixedly connected to the inner side wall of the bin body shell 21.

[0041] Through the above-mentioned structural setting, first, the workbench 1 is moved to the upper end of the pipe sandblasting device through the moving structure 5, and some pipes are placed in the storage bin 2. The pipes fall through the storage bin 2, and finally the pipes move to the distribution structure 3, and the distribution structure 3 sorts the pipes so that the pipes pass through the distribution structure 3 alone and enter the conveying structure 4, and then the conveying structure 4 transports the pipes to the pipe sandblasting device.

[0042] In some embodiments, Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the upper part of the warehouse shell 21 is open, one side of the warehouse shell 21 is fixedly connected to the workbench 1, and the other side of the warehouse shell 21 is provided with a conveying port 211, and the upper edge of the conveying port 211 is inclined downwardly toward the direction of the partition plate 22 and provided with a guide plate 212; a placement groove 221 is provided on the partition plate 22, and a blocking plate 222 is rotatably connected in the placement groove 221, and a rotating shaft 223 passes through the blocking plate 222 along the axial direction, and the rotating shaft 223 is provided with a One end of the rotating shaft 22 passes through the partition plate 22 and is fixedly connected to a rotating handle 224, the other end of the rotating shaft 223 is rotatably connected to the partition plate 22, and a lap column 225 is provided on the lower surface of the rotating handle 224; a sliding groove 213 is provided on the warehouse body shell 21, and a support block 214 is provided in the sliding groove 213, and the support block 214 is L-shaped, one end of the support block 214 is slidably connected to the sliding groove 213, and the other end of the support block 214 is overlapped with the lap column 225.

[0043] Through the above-mentioned structural arrangement, the pipe enters the interior of the silo from the opening on the upper part of the silo shell 21, and the partition plate 22 separates the pipe so that the pipe is diverted to the first channel 23 and the second channel 24, and the first channel 23 and the second channel 24 can only allow a single pipe to pass through, and then the blocking plate 222 is rotated to a position flush with the partition plate 22, so that the pipe falls from the first channel 23. When the pipe in the first channel 23 finishes falling, the rotating handle 224 is rotated to rotate the blocking plate 222 to a position perpendicular to the partition plate 22, and then the support block 214 is slid to the lower end of the lap column 225 to overlap with the lap column 225.

[0044] In some embodiments, such as Figure 1 , Figure 4 and Figure 8 As shown, the distribution structure 3 includes a first driving shaft 31 and a distribution plate 32, and the two ends of the warehouse shell 21 are respectively connected with connecting plates 33, and the connecting plates 33 are rotatably connected to the first driving shaft 31. A plurality of the distribution plates 32 are arranged on the surface of the first driving shaft 31, and one end of the first driving shaft 31 passes through the connecting plate 33 and is fixedly connected with a first motor 34.

[0045] Through the above-mentioned structural arrangement, the pipes fall from the storage bin 2 and move to the distribution plate 32. The first motor 34 drives the distribution plate 32 to move to distribute the pipes. The gap between the two distribution plates 32 is only large enough for one pipe to pass through. In this way, the pipes can pass through alone, thereby avoiding pipe blockage and controlling the transportation speed of the pipes.

[0046] In some embodiments, Figure 1 and Figure 3 As shown, the conveying structure 4 includes a rolling shaft 41 and a conveyor belt 42. Placement openings 43 are respectively opened at both ends of the workbench 1 in a direction perpendicular to the first driving shaft 31. Multiple rolling shafts 41 are rotatably connected to the two side walls of the placement opening 43. The center of the rolling shaft 41 extending out of the placement opening 43 is fixedly connected to a transmission shaft 44. The transmission shaft 44 connects two rolling shafts 41 extending out of the placement opening 43, and the transmission shaft 44 is fixedly connected to a second motor 45. The conveyor belt 42 is sleeved on multiple rolling shafts 41.

[0047] Through the above-mentioned structural arrangement, the second motor 45 drives the rolling shaft 41 to rotate, thereby driving the conveyor belt 42 to rotate, and further driving the pipe to move, and the conveyor belt 42 smoothly transports the pipe to the pipe sandblasting device.

[0048] In some embodiments, Figure 1As shown, the movable structure 5 includes a column 51 and a slide 52. Four columns 51 are arranged on the lower surface of the workbench 1, wherein two of the columns 51 are arranged at two right-angled sides of the workbench 1 and are located below the warehouse shell 21, and the other two columns 51 are arranged along the radial direction of the rolling axis 41, and the two columns 51 are arranged in a straight line with the two columns 51 at the two right-angled sides of the workbench 1; the slide 52 is arranged at the lower end of the column 51, and the slide 52 is slidably connected to the column 51, and a pulley 53 is arranged at the lower end of the column 51, and the pulley 53 is slidably connected to the slide 52, and a second driving shaft 54 ​​is fixedly connected between the pulleys 53 on the two columns 51 at the two right-angled sides of the workbench 1, and a driving motor 55 is fixedly connected to one end of the second driving shaft 54.

[0049] Through the above-mentioned structural arrangement, the driving motor 55 drives the driving shaft to rotate, thereby causing the pulley 53 to move, and further driving the column 51 and the workbench 1 to move, thereby adjusting the distance and position between the workbench 1 and the pipe sandblasting device.

[0050] In some embodiments, Figure 1 As shown, a cylinder 6 is provided between the column 51 and the workbench 1 .

[0051] Through the above-mentioned structural arrangement, when the workbench 1 is moved to the vicinity of the pipe sandblasting device, the height of the workbench 1 and the pipe sandblasting device can be controlled by adjusting the extension and retraction of the cylinder 6, so that the pipe can be better placed on the pipe sandblasting device.

[0052] In some embodiments, Figure 6 As shown, a rectangular opening 25 is formed on a side of the bin housing 21 away from the distribution structure 3 , and a flat push plate 26 is slidably connected inside the rectangular opening 25 .

[0053] With the above-mentioned structural arrangement, when the workbench 1 is in motion or stopped, the push plate 26 is pushed into the rectangular opening 25 so that the push plate 26 abuts against the partition plate 22 , thereby blocking the pipes in the first channel 23 .

[0054] In some embodiments, Figure 5 As shown, the upper end of the partition plate 22 is arc-shaped.

[0055] Through the above-mentioned structural arrangement, the pipe can be better diverted and guided to the first channel 23 and the second channel 24 .

[0056] In some embodiments, Figure 5 As shown, a slide 7 is provided from the bin shell 21 toward the first driving shaft 31 .

[0057] The above-mentioned structural arrangement can buffer the falling of the pipe fittings and enable the pipe fittings to move to the distribution plate 32, thereby assisting the pipe fittings.

[0058] In summary, when the pipe fittings need to be sandblasted, first push the push plate 26 into the rectangular groove, rotate the blocking plate 222 to a position flush with the partition plate 22, then put the pipe fittings into the storage bin 2, and then start the drive motor 55 to drive the drive shaft to rotate, so that the pulley 53 moves, and then drive the column 51 and the workbench 1 to move, so as to adjust the distance and position between the workbench 1 and the pipe fitting sandblasting device. When the workbench 1 moves to the vicinity of the pipe fitting sandblasting device, the height of the workbench 1 and the pipe fitting sandblasting device can be controlled by adjusting the extension and contraction of the cylinder 6, so as to better allow the pipe fittings to fall onto the pipe fitting sandblasting device. Then, the push plate 26 is slid out, and the first motor 34 and the second motor 45 are started. The single pipe falls from the first channel 23 onto the slope, and then moves to the distribution plate 32. The distribution plate 32 can control the movement speed of the pipe and move the single pipe to the conveyor belt 42. The conveyor belt 42 then transports the pipe to the pipe sandblasting device. When the pipe in the first channel 23 is transported, the blocking plate 222 is rotated to a position perpendicular to the partition plate 22, and the support block 214 is slid to the lower end of the overlapping column 225 to overlap with the overlapping column 225, so that the pipe falls from the second channel 24.

[0059] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0060] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
