[0004] The inventor finds that at least the following problems exist in the prior art: During the reciprocating movement of the piston rod of the oil cylinder of the hydraulic baling press, a small amount of oil film will still adhere to the piston rod. With long-term work, the accumulated oil film may cause oil film accumulation at the dustproof ring of the lower cavity of the hydraulic baling press. Due to the particularity of the feeding mode of the hydraulic baling press, part of the dust will separate from the tobacco leaves during the free fall of the tobacco leaves, resulting in excessively high dust content per cubic meter in the actual working environment. These dusts will be adsorbed on the piston rod and combined with a small amount of oil film when the piston rod reciprocates, forming oil-containing dust. Tobacco products belong to the category of food processing, and oil stains are a serious quality problem for tobacco pollution, and the industry urgently needs to eliminate this risk.

[0046] Referring to Figures 1-5 The embodiments of the present application provide an oil seepage prevention device, which comprises a first clamping device 1, a second clamping device 2, a connecting assembly 3 and an oil absorption component 4. The first clamping device 1 comprises a first half ring 11 and a second half ring 12 which are assembled to form a ring shape, and the first half ring 11 and the second half ring 12 are detachably connected and form a first through hole. The second clamping device 2 comprises a third half ring 21 and a fourth half ring 22 which are assembled to form a ring shape, and the third half ring 21 and the fourth half ring 22 are detachably connected and form a second through hole. The connecting assembly 3 comprises a first connecting piece 31 and a second connecting piece 32; the first half ring 11 and the third half ring 21 are arranged at intervals and are detachably connected, and the second half ring 12 and the fourth half ring 22 are arranged at intervals and are detachably connected.

[0047] Referring to Figures 1-7 , in particular Figure 6 , and Figure 7, the first clamping device 1 comprises two halves: a first half ring 11 and a second half ring 12, which partially overlap and coincide to form a stepped clamping device. The first half ring 11 and the second half ring 12 are spliced to form a complete ring, and the first through hole formed by the first half ring 11 and the second half ring 12 has a relatively large size, which is larger than the size of the cylinder barrel of the oil cylinder of the hydraulic baler. The first clamping device 1 surrounds the outside of the cylinder barrel of the oil cylinder of the hydraulic baler and is detachably fixedly connected with the cylinder barrel. The cylinder barrel provides support for the first clamping device 1.
[0048] The second clamping device 2 comprises a third half ring 21 and a fourth half ring 22 spliced to form a ring, which partially overlap and coincide to form a stepped clamping device. The second clamping device 2 is located outside the piston rod of the oil cylinder, and the position of the second clamping device 2 remains unchanged during the reciprocating movement of the piston rod. There is a gap between the inner wall of the second clamping device 2 and the outer wall of the piston rod, and the oil absorption component 4 is installed in the gap.
[0049] In this article, the stepped clamping device refers to that the first clamping device 1 and the second clamping device 2 each comprise a first circular ring surrounded by two vertical plates and a second circular ring surrounded by two flat plates, and the first circular ring and the second circular ring are fixedly connected or integrated. A step, also known as a staircase, is formed at the junction of the first circular ring and the second circular ring. Part of the edge of the first circular ring has a flat plate folded outward to form an overlapping area. In other words, the first half ring 11 and the second half ring 12 have the same structure and each comprise a vertical plate and a flat plate. The third half ring 21 and the fourth half ring 22 also have the same structure and each comprise a vertical plate and a flat plate.
[0050] Referring to Figure 1 and Figure 2 , the first clamping device 1 and the second clamping device 2 are detachably fixedly connected through the connecting assembly 3. Since the first clamping device 1 and the second clamping device 2 each adopt two half rings for splicing, the connecting assembly 3 can also be provided with a first connecting piece 31 and a second connecting piece 32 correspondingly, the first connecting piece 31 is used to realize detachable fixed connection of the first half ring 11 and the third half ring 21, and the second connecting piece 32 is used to realize detachable fixed connection of the second half ring 12 and the fourth half ring 22.
[0051] In some embodiments, a plurality of first connecting pieces 31, such as two, are arranged dispersedly along the circumference of the first half ring 11, and the two first connecting pieces 31 are arranged uniformly along the axial direction of the first half ring 11. In this way, the reliability of the connection between the first half ring 11 and the third half ring 21 can be increased.
[0052] In some embodiments, a plurality of second connecting pieces 32, such as two, are arranged dispersedly along the circumference of the second half ring 12, and the two second connecting pieces 32 are arranged uniformly along the axial direction of the second half ring 12. In this way, the reliability of the connection between the second half ring 12 and the fourth half ring 22 can be increased.
[0053] In some embodiments, the first connector 31 and / or the second connector 32 are lead screws. Lead screw connections are more reliable and can effectively limit positional changes caused by forces acting on the second clamping device 2.
[0054] The oil-absorbing component 4 includes a first end 41 and a second end 42. The oil-absorbing component 4 is a bendable part. After installation, the first end 41 and the second end 42 are joined together to form a ring. (See attached image.) Figure 8 As shown, the shape of the oil-absorbing component 4 is adapted to the inner wall shape of the second clamping device 2, and the two fit together.
[0055] In some embodiments, the inner wall of the third semi-ring 21 is provided with a first groove, and the inner wall of the fourth semi-ring 22 is provided with a second groove. The oil-absorbing component 4 is inserted into the first and second grooves. When the oil-absorbing component 4 is full of oil, a new oil-absorbing component can be replaced. The oil-absorbing component 4 can be removed or installed as a whole, which is convenient for disassembly and assembly and is secure and reliable. The oil-absorbing component 4 can be made of oil-absorbing felt, specifically, industrial oil-absorbing felt with a thickness of 1.8mm to 2.2mm, such as 1.8mm, 2mm, or 2.2mm.
[0056] The above technical solution, through precise calculation of material compression and design of its thickness, provides appropriate positive pressure, thereby obtaining suitable friction and preventing accelerated wear. Utilizing capillary action, the felt absorbs oil accumulated from the oil film, thus preventing oil fumes and excessive oil film buildup during material flow. This type of industrial oil-absorbing felt can absorb five times its own weight in oil. It takes approximately 5.7 seconds to completely saturate 5ml of oil. Furthermore, in a test with 100 cycles of motion, no wear was observed on the piston rod surface, nor on the surface of the industrial oil-absorbing felt, demonstrating its reliable durability, lack of shedding risk, and resistance to wear.
[0057] In some embodiments, the first end 41 and the second end 42 are joined together without gaps. The first end 41 and the second end 42 are assembled to form a 360° annular structure. The first end 41 and the second end 42 can wrap around the outer wall of the piston rod. Therefore, no matter where there is oil or dust on the outer wall of the piston rod, as long as that location passes through the oil suction component 4 during the reciprocating motion of the piston rod, the oil suction component 4 can absorb the oil and dust.
[0058] See Figure 8 In some embodiments, the first end 41 includes a first protrusion 411 and a first concave portion 412, and the second end 42 includes a second concave portion 421 and a second protrusion 422. The first protrusion 411 is inserted into the first concave portion 412, and the second protrusion 422 is inserted into the second concave portion 421. The two ends of the first end 41 and the two ends of the second end 42 are joined together to form a flat and seamless transition surface.
[0059] The joint of the first end 41 and the second end 42 is seamless, the structure of the male and female buckles is such that the joint gap is staggered, the through gap of the first end 41 and the second end 42 at the joint is 0mm, there is no through gap, the contact surface is smooth, the oil leakage at the gap is effectively prevented, and the assembly and disassembly are convenient, firm and reliable.
[0060] In use, the position of the first clamping device 1 is fixed and does not stretch and shrink with the stretching and shrinking movement of the piston rod of the oil cylinder of the hydraulic packing machine. The position of the second clamping device 2 detachably and fixedly connected with the first clamping device 1 is also fixed. The piston rod of the oil cylinder passes through the first through hole of the first clamping device 1 and the second through hole of the second clamping device 2. During the reciprocating linear movement of the piston rod, the oil suction component 4 is always in abutment with the outer wall of the piston rod, the oil suction component 4 is in dynamic friction with the piston rod, the dust and oil attached to the outer wall of the piston rod can be adsorbed into the interior of the oil suction component 4 by the oil suction component 4, the dust and oil attached to the outer wall of the piston rod are cleaned, the oil dust is not easy to form on the outer wall of the piston rod, the outer wall of the piston rod can be kept clean, the probability of the dust in the air being adsorbed on the piston rod is greatly reduced, the oil dust is almost not formed, the pollution of the oil to the tobacco products in the tobacco production process is effectively reduced, and the safety of the tobacco production is improved.
[0061] In some embodiments, the oil seepage prevention device further comprises a dustproof component 5 installed on the inner wall of the second clamping device 2. Since the second clamping device 2 is formed by splicing two half rings of the third half ring 21 and the fourth half ring 22, the dustproof component 5 can be installed after the third half ring 21 and the fourth half ring 22 are spliced to form a complete ring. The third half ring 21 and the fourth half ring 22 are respectively provided with mounting grooves, and after the third half ring 21 and the fourth half ring 22 are spliced to form a complete ring, the two end mounting grooves form a ring-shaped groove. The dustproof component is, for example, a dustproof ring. The plane where the dustproof ring is located is perpendicular to the axial direction of the second clamping device 2. The dustproof ring is located on the side of the oil suction component 4 away from the first clamping device 1. The dustproof ring plays a good dustproof role and further reduces the dust attached to the surface of the piston rod of the oil cylinder.
[0062] The utility model embodiment further provides a hydraulic packing machine comprising the oil seepage prevention device provided in any of the technical solutions of the utility model.
[0063] In some embodiments, the hydraulic packing machine further comprises an oil cylinder, the oil cylinder comprising a cylinder barrel and a piston rod; the piston rod being slidably installed on the cylinder barrel; the piston rod passing through the first through hole and the second through hole of the oil seepage prevention device; the first clamping device 1 being detachably and fixedly connected with the cylinder barrel, the second clamping device 2 being located on the outer periphery of the piston rod and having a gap therebetween, and the oil suction component 4 being located in the gap between the piston rod and the second clamping device 2.
[0064] In the embodiment with the dustproof component, the dustproof component and the oil absorption component 4 are arranged along the axial direction of the piston rod. The dustproof component can sweep the dust attached to the surface of the piston rod, so that the oil absorption component 4 has better oil absorption effect.
[0065] The hydraulic packing machine provided by the technical scheme has the advantages that the oil liquid in the lower cavity of the hydraulic packing machine can be effectively prevented from accumulating, the oil liquid can be effectively isolated from the dustproof ring, the dust adsorbed on the piston rod can be scraped, the occurrence of abnormal wear can be prevented, and the phenomenon that the oil smoke and dust are generated during the movement of the pre-press oil cylinder of the hydraulic packing machine can be effectively reduced or even eliminated.
