[0049] Embodiment 1

[0050] As Figure 1 and Figure 2 shown, a roller structure 100 provided in this embodiment, a roller structure 100, includes: an outer layer 110, an inner layer 120, and a reinforcing rib plate 130;

[0051] The outer layer 110 is made of rubber material, the outer layer 110 is cylindrical, and a plurality of protrusions 140 are arranged on the surface of the outer layer 110 along the circumferential direction, and the protrusions 140 extend along the length direction of the outer layer 110; the inner layer 120 is polygonal, and a plurality of reinforcing rib plates 130 are arranged between the outer layer 110 and the inner layer 120 to enhance the overall structural strength;

[0052] Since the outer layer 110 is made of rubber material, combined with the protrusions 140 on the surface of the outer layer 110, during use, the entering stones will be clamped between the gaps of two adjacent roller structures 100. As the roller structure 100 rotates, the stones will squeeze and deform the rubber outer layer 110 of the roller structure 100, and finally discharge the stones from the equipment, effectively solving the problems of deformation of the steel roller or damage of the bearing in the prior art.

[0053] As a preferred implementation, the inner layer 120 and the reinforcing rib plate 130 can also be made of rubber material. Of course, the inner layer 120 and the reinforcing rib plate 130 can also be made of metal material.

[0054] As a preferred implementation, the inner layer 120 is set to be square, hexagonal, octagonal or other shapes, and is used in combination with a plurality of reinforcing rib plates 130 to enhance the supporting effect on the outer layer 110.

[0055] Embodiment 2

[0056] As Figures 3 to 10 shown, a roller shaft assembly provided in this embodiment includes a transmission shaft body 200, a positioning sleeve 300, and a plurality of the roller structures 100 in the above Embodiment 1;

[0057] Among them, multiple roller structures 100 are sequentially sleeved on the transmission shaft body 200 through the inner layer 120. The multiple roller structures 100 are divided into a first roller structure 101 and a second roller structure 102;

[0058] The second roller structure 102 is the roller structure 100 sleeved at both ends of the transmission shaft body 200; the first roller structure 101 is the multiple roller structures 100 located between the two second roller structures 102;

[0059] Both ends of the shaft head 210 of the transmission shaft body 200 are exposed outside the second roller structure 102;

[0060] Positioning sleeves 300 are respectively sleeved on both ends of the shaft head 210 of the transmission shaft body 200, and the positioning sleeves 300 extend between the inner layer 120 and the outer layer 110 of the second roller structure 102; used to position the axial side of the second roller structure 102.

[0061] Refer to Figure 6 Preferably, the positioning sleeve 300 includes a circular positioning plate 310 and a sleeve body 320; the sleeve body 320 is connected to the outer edge of the positioning plate 310;

[0062] The positioning plate 310 is sleeved on the shaft head 210 of the transmission shaft body 200, and the positioning plate 310 abuts against the inner layer 120 and the reinforcing rib plate 130 of the second roller structure 102, thereby limiting the multiple roller structures 100.

[0063] Refer to Figure 3 In addition, the roller shaft assembly in this embodiment further includes a snap ring 400. The snap ring 400 is located on the side of the positioning sleeve 300 away from the first roller structure 101. Card slots are respectively provided on both ends of the shaft head 210 of the transmission shaft body 200, and the snap ring 400 is clamped in the card slots, used to position the axial side of the positioning sleeve 300.

[0064] As a preferred embodiment, among the multiple first roller structures 101, the ends of the outer layers 110 of two adjacent first roller structures 101 are assembled in the form of a card slot cooperating with a protrusion;

[0065] For example, a protrusion is provided at the end of the outer layer 110 of one of the first roller structures 101, and a card slot is provided at the end of the outer layer 110 of the other first roller structure 101. The quick assembly of two adjacent first roller structures 101 is realized through the insertion method, and the cooperation between the two is also made closer.

[0066] Since the end of the transmission shaft body 200 needs to be assembled with the side plate 1 of the baler through bearings and also needs to be connected to the driving device, there is a certain gap between the end face of the packing roller and the side plate 1 of the packing bin. It is very easy for the recycled residual film to enter the gap, which affects the rotation of the conveying roller and the shaft head 210 of the packing roller, causing the problems of jamming of the conveying roller and the packing roller.

[0067] Therefore, the roller shaft assembly in this embodiment further includes a sealing assembly;

[0068] As Figures 5 to 10 shown, the sealing assembly includes a bearing inner seat 500 and a bearing outer seat 600;

[0069] Among them, the bearing inner seat 500 is in a sleeve shape and sleeved outside the sleeve body 320. A baffle 510 is provided at the end of the bearing inner seat 500 away from the sleeve body 320. The outer side of the baffle 510 contacts the side plate 1 of the baler, and a limiting hole 511 is provided in the middle of the baffle 510;

[0070] The bearing outer seat 600 is in a disc shape. A limiting protrusion 610 is provided on one side of it. A through hole for assembling the bearing is provided in the middle of the bearing outer seat 600 and penetrates the limiting protrusion 610;

[0071] The bearing outer seat 600 is located outside the side plate 1 of the baler. The bearing outer seat 600 is sleeved on the shaft head 210 of the transmission shaft body 200 through a bearing (omitted in the figure), and the limiting protrusion 610 extends into the limiting hole 511 of the baffle 510;

[0072] The bearing inner seat 500, the side plate 1 and the bearing outer seat 600 are connected by bolts.

[0073] In application, the sleeve body 320, the bearing inner seat 500 and the baffle 510 form a relatively sealed environment, which can prevent the residual film from entering the gap between the conveying roller and the end face of the packing roller and the side plate of the packing bin, reduce the operation failure rate of the residual film picking and baling machine, and improve the operation efficiency of the residual film recycling operation.

[0074] Referring to Figure 9 and Figure 10 , as a preferred implementation, a sealing protrusion 620 is further provided on the side surface of the bearing outer seat 600. The sealing protrusion 620 is located on the side of the limiting protrusion 610 close to the second roller structure 102. A stepped surface is provided on the shaft head 210 of the transmission shaft body 200. The end of the limiting protrusion 610 abuts against the stepped surface, and the limiting protrusion 610 can play a sealing role for the bearing.

[0075] Referring to Figure 7 and Figure 8 , preferably, a plurality of mounting nuts 520 are welded on the circumferential side of the baffle 510 of the bearing inner seat 500, and the screw holes of the mounting nuts 520 penetrate through the baffle 510;

[0076] A plurality of mounting holes 630 for assembling bolts are provided on the circumferential side of the outer bearing seat 600, and the positions of the mounting holes 630 correspond to the positions of the mounting nuts 520.

[0077] 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 on 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.
