Especially when there is a height difference between the discharging position and the stacking position, most of them need to be manually handled, and the handling personnel need to go up and down slopes continuously during the handling process, which is time-consuming and laborious and seriously affects the loading and unloading progress.

[0059] In an embodiment of the present invention, please refer to Figures 1 - 9 , the feeding component and the discharging component have the same structure;

[0060] Here, taking the feeding component as an example, its specific structure will be further described. The feeding component includes:

[0061] The support frame 4 fixedly installed on the first supporting bracket 3, there are two groups of the support frame 4, and the length of the support frame 4 closer to the housing 1 is less than the length of the support frame 4 farther from the housing 1;

[0072] A limit groove 20, and multiple groups of the limit grooves 20 are equidistantly provided on the handling plate 13, and the limit grooves 20 are perpendicular to the strip-shaped openings 19;

[0073] and a second rotating shaft 17 rotatably installed at the end of the handling plate 13, a magnet 18 for adsorbing the goods in the limiting groove 20 is arranged on the second rotating shaft 17; wherein the cross-section of the limiting groove 20 is a semi-circular structure, and the center of the circle is located on the axis of the second rotating shaft 17, which is preferably applicable to carrying cylindrical goods with the same diameter as the limiting groove 20. When carrying cylindrical goods of different sizes, the handling plate 13 can be replaced;

[0074] A friction wheel 16 is also fixedly installed on the second rotating shaft 17;

[0075] An auxiliary cleaning component for cooperating with the handling component to clean the goods during the ascending process is also arranged on the housing 1;

[0076] The auxiliary cleaning component includes:

[0077] A support plate 7 arranged on the housing 1, a guiding square rod 8 and a plurality of driving strips 9 are fixedly installed on the support plate 7, and a strip-shaped groove for engaging with the friction wheel 16 is formed in the driving strip 9;

[0078] A lifting plate 24 slidably installed on the guiding square rod 8, and a first spring 23 for elastically pulling the lifting plate 24 is also arranged on the support plate 7;

[0079] A linkage frame 25, and a control component for adjusting the working position of the linkage frame 25 is arranged in the lifting plate 24;

[0080] A dust suction hood 14 arranged at the end of the linkage frame 25, a cleaning member 26 corresponding to the position of the limiting groove 20 is arranged at the bottom of the dust suction hood 14, and a dust suction hole 27 is formed between adjacent cleaning members 26. A cavity communicating with the dust suction hole 27 is formed in the dust suction hood 14;

[0081] And a suction pipe 33 communicating with the cavity in the dust suction hood 14; during use, the suction pipe 33 is connected to an external dust suction device, and the dust suction device can be a small vacuum cleaner, which is not specifically limited here;

[0082] The control component includes:

[0083] A negative pressure cavity 30 opened in the lifting plate 24, a piston 31 is slidably installed in the negative pressure cavity 30, and a second spring 28 for pulling the piston 31 is arranged at the top in the negative pressure cavity 30;

[0084] A push-pull rod 29 slidably installed on the lifting plate 24, one end of the push-pull rod 29 is fixedly connected to the linkage frame 25, and the other end of the push-pull rod 29 is fixedly connected to the piston 31;

[0085] and a conduit 32 for communicating between the suction pipe 33 and the negative pressure chamber 30; wherein one side of the suction pipe 33 close to the linkage 25 is a telescopic structure.

[0086] In this embodiment, the conveyor belt 10 is of an oval structure. The second motor drives the first rotating shaft 11 to rotate, and the conveyor belt 10 can be driven to move by using the belt pulley 34. The support shaft 35 and the handling plate 13 can be driven to move by using the conveyor belt 10. When the handling plate 13 moves above or below the material conveying roller 5, the material conveying roller 5 can penetrate the handling plate 13 by means of the strip-shaped opening 19. When the handling plate 13 moves upward from below the material conveying roller 5 of the feeding assembly, the handling plate 13 can lift the goods at the end, so that the goods can fall into the limiting groove 20, where the limiting groove 20 corresponds to the groove position on the material conveying roller 5. At the same time, the telescopic cylinder 15 drives the push plate 6 to press the goods, so that the end of the goods can contact the magnet 18 and be adsorbed by the magnet 18, thereby improving the stability during handling. When the handling plate 13 moves upward to below the dust suction cover 14 and continues to move upward, the handling plate 13 will push the dust suction cover 14 to move upward, so that the cleaning member 26 presses on the goods. The cleaning member 26 can be a sponge block. At the same time, the dust suction device is started. Through the cooperation setting of the suction pipe 33 and the conduit 32, a negative pressure can be generated in the negative pressure chamber 30, so that the piston 31 moves downward. The piston 31 will drive the linkage 25 to move downward by using the push rod 29, thereby increasing the pressing force of the dust suction cover 14 and the cleaning member 26 on the goods. Through the cooperation setting of the friction wheel 16 and the driving strip 9, when the handling plate 13 moves upward, the friction wheel 16 can drive the second rotating shaft 17 to rotate, so as to drive the magnet 18 and the goods to rotate at the bottom of the cleaning member 26, and cooperate with the dust suction function of the dust suction holes 27 to effectively remove dust. When the handling plate 13 is about to move to the top and is about to move to the side of the discharging assembly, the dust suction device stops working. At the moment of stopping work, the second spring 28 pulls the piston 31 upward, so that the push rod 29 pushes the linkage 25 upward, and further enables the dust suction cover 14 and the cleaning member 26 to be separated from the goods briefly, facilitating the movement of the handling plate 13 to the side of the discharging assembly. After the handling plate 13 is completely separated from the dust suction cover 14, the first spring 23 will pull the lifting plate 24 back to its original position; when the handling plate 13 loaded with goods moves downward from above the discharging assembly, due to the blocking effect of the material conveying roller 5, the goods can be separated from the magnet 18 and fall on the material conveying roller 5 and be transported out by the material conveying roller 5; by using the counterweight function of the balance weight 21, the center of gravity of the handling plate 13 is effectively reduced, so that the handling plate 13 always maintains a horizontal state.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
