Description

Technical Field

[0001] The invention relates to the technical field of leather production, in particular to leather production and processing equipment. Background Art

[0002] Impregnation allows the dehydrated raw hides to fully absorb moisture and reach a fresh hide state, laying a good foundation for the subsequent chemical treatment process and is an important step in leather production.

[0003] The main means of impregnation is to immerse the original hide in a well-proportioned bath liquid, and then turn the leather for 10 minutes every 2 hours or so. However, there will be a small amount of animal fat on the surface of the original hide. At the same time, since the impregnation time is often long, it is necessary to clean up in time after the fat falls off, especially when the room temperature is high, otherwise it is easy to cause the bath liquid to stink. The main existing solution is to use a grate to manually salvage the grease and debris floating on the liquid surface of the bath liquid before or after each turning of the leather. However, this method is slow and incomplete. At the same time, the bath liquid in the bathtub and the electrical facilities in the bathtub will also pose a danger to humans.

A plurality of filter plates 8 are rotatably connected to the frame plate 6. The rotating shafts of the filter plates 8 are all fixedly connected to the first gears 9. The first gears 9 are all meshed with the first rack rods 10. The tops of the first rack rods 10 are commonly fixedly connected to the cross bars 11. The cross bars 11 are located inside the receiving grooves 7. The tops of the left and right sides of the cross bars 11 pass through the receiving grooves 7 and extend to the top of the frame plate 6. The cross bars 11 are slidably connected to the frame plate 6. , two first springs 12 are fixedly connected to the top of the cross bar 11, and the two first springs 12 are fixedly connected to a pull rod 13, and the two pull rods 13 are slidably connected to the filter box 4 and the tops of the pull rods 13 are located outside the filter box 4, and a push rod 14 is arranged below the outer ends of the two pull rods 13, and the two push rods 14 are located on the left and right sides of the bathtub 2, and the two push rods 14 are respectively slidably connected to the two support frames 1 in the vertical direction, and the flipping group can provide the push rod 14 with power to slowly slide upward when the stirring shaft 3 rotates;

[0037] The bathtub 2 is provided with a collecting group for collecting the grease and debris filtered out by the filtering group.

[0038] The two filter boxes 4 are both fixedly connected with a limiting frame 33 .

[0039] The collecting group includes two driving plates 15 and a triggering group. The two driving plates 15 are both located inside the filter box 4 and their ends extend to the outside of the filter box 4. The two driving plates 15 are respectively slidably connected to the two filter boxes 4. A second spring 16 is fixedly connected between the two driving plates 15 and the two filter boxes 4. The two driving plates 15 are both slidably connected to a scraper 17. A third spring 37 is fixedly connected between the scraper 17 and the inside of the driving plate 15. The two scrapers 17 are respectively attached to the two frame plates 6. The side walls of the two filter boxes 4 are provided with collecting grooves 18, and the collecting grooves 18 are both located on one side of the scraper 17.

[0040] The trigger group can cooperate with the flipping group during operation to provide power for the collection group located above.

[0041] The side wall of the filter box 4 is threadedly connected with a disassembly plate 35 through bolts 34, and the disassembly plate 35 is slidably connected to the collection tank 18.

[0042] The trigger group includes two baffles 19, which are located directly below the top rod 14. When the top rod 14 rises, it can drive the baffle 19 and the pull rod 13 to rise at the same time. The two baffles 19 are slidably connected to the vertical rod 20, and the two vertical rods 20 are respectively rotatably connected to the two support frames 1. The rotation axes of the two vertical rods 20 are sleeved with torsion springs 38. After the flipping group drives the bathtub 2 to rotate, the outer end of the driving plate 15 at the top will contact the baffle 19, and then push the driving plate 15 to slide along the filter box 4 to the side away from the collecting tank 18. During the rotation of the bathtub 2, the pull rod 13 can push the baffle 19 and the vertical rod 20 to rotate around the rotation axis, so that the baffle 19 makes way for the pull rod 13.

[0043] like Figure 1-Figure 10 As shown:

[0044] The support frame 1 provides support for the bathtub 2. When leather (raw hide) needs to be placed, the leather can be placed inside the bathtub 2 by opening the opening and closing plate 5. In actual use, pipes for water inlet and water outlet are provided at the upper and lower parts of the bathtub 2. Solutions can be added to the bathtub 2 through the pipes so that the leather can be impregnated. The height of the added solution needs to be kept above the frame plate 6 inside the filter box 4 above, but cannot exceed the collection tank 18.

[0045] The driving plate 15 inside the upper filter box 4 is in contact with the baffle 19 and is pushed back by the baffle 19 (the baffle 19 and the vertical rod 20 will not rotate under the restriction of the torsion spring 38, thereby pushing the driving plate 15 back), so at this time the driving plate 15 will slide along the filter box 4 to the side away from the collection tank 18, and at this time the second spring 16 is stretched, and when the driving plate 15 moves, the plate body inside the filter box 4 will release the obstruction to the collection tank 18, and the collection tank 18 will be opened, and the liquid level of the immersion liquid is at the collection tank 1 8 and above the frame plate 6, so during the process of the leather being immersed and the stirring shaft 3 rotating, the grease and debris floating out will float above the liquid surface, and then the grease and debris will be inside the filter box 4, and the filter plate 8 is in a vertical state, so the grease and debris will float above the filter plate 8, because the flipping group will slowly drive the top rod 14 to slide upward along the support frame 1 when driving the stirring shaft 3 to rotate for ten minutes, and the leather can be rotated inside the bathtub 2 through the slow rotation of the stirring shaft 3, so that the grease and debris can float up;

[0046] During the rising process of the top rod 14, the pull rod 13 and the baffle 19 will be lifted respectively, and the vertical distance of the baffle 19 is long, so when the baffle 19 rises along the vertical rod 20, it will not immediately lose contact with the driving plate 15. When the pull rod 13 rises, it will slide and rise along the filter box 4 and pull the cross bar 11 and the first rack rod 10 to slide and rise inside the accommodating groove 7 through the first spring 12. The first rack rod 10 will mesh with the first gear 9 and rotate the first gear 9 to rotate the filter plate 8 from the vertical state to the horizontal state. When the filter plate 8 is in the water, After the flat state, the gap on the frame plate 6 will be blocked, so that the frame plate 6 and the filter plate 8 form a whole, and then as the cross bar 11 rises, the frame plate 6 and the filter plate 8 will be driven to rise at the same time. At this time, the grease and debris will be above the filter plate 8 and rise with the rise of the filter plate 8. When the frame plate 6 rises, its top will lift the scraper 17, so that the scraper 17 slides and rises along the driving plate 15. At this time, the third spring 37 will be gradually compressed, so that the scraper 17 can be close to the top of the frame plate 6 when the frame plate 6 and the filter plate 8 rise.

[0047] When the push rod 14 pushes the baffle plate 19 to rise over the driving plate 15, the frame plate 6 and the filter plate 8 will also rise to the limit, at this time the first spring 12 will stretch, and then the push rod 14 will continue to rise until the baffle plate 19 passes over the driving plate 15, and the driving plate 15 will quickly slide and reset along the filter box 4 under the elastic restoring action of the second spring 16, and at this time the scraper 17 will quickly move from the side of the top of the filter plate 8 away from the collecting tank 18 to the collecting tank 18, and at this time the scraper 17 will scrape the grease and debris above the filter plate 8 to the inside of the collecting tank 18, until the grease and debris enter the collecting tank 18, and then the driving plate 15 and the scraper 17 will fit with the collecting tank 18 and close the collecting tank 18 to prevent the grease and debris from leaking out, and at this time the stirring shaft 3 will also complete the rotation;

[0048] Then the flipping group will first drive the bathtub 2 to rotate 180 degrees clockwise. When the bathtub 2 rotates, the pull rod 13 at the top will fit the arc-shaped end of the top rod 14 and rotate with the bathtub 2. When the pull rod 13 rotates to contact the baffle 19, it will force the baffle 19 and the vertical rod 20 to rotate around the rotation axis and compress the torsion spring 38, so that the vertical rod 20 and the baffle 19 rotate when they contact the pull rod 13 to make way for the pull rod 13. When the pull rod 13 rotates to the other side of the vertical rod 20, the pull rod 13 and the cross bar 11 will slide back to their original position. At this time, the third spring 37 will also be scraped The plate 17 gives the frame plate 6 a thrust to reset. When the frame plate 6 is reset, the filter plate 8 will be in a vertical state again. During the rotation of the bathtub 2, the flipping group will drive the top rod 14 to reset. After the bathtub 2 rotates 180 degrees, the filter box 4 originally at the bottom will rotate to the top, and the outer end of the driving plate 15 inside it will contact the baffle 19 and be blocked by the baffle 19 to slide along the filter box 4 and compress the second spring 16. Then the flipping group will drive the stirring shaft 3 to rotate again and provide the top rod 14 with the power to rise, thereby completing a cycle.

[0049] In this way, during the rotation of the stirring shaft 3, the leather inside the bathtub 2 can be slowly stirred and turned over. First, it is convenient for the debris and grease inside the liquid below the leather to float up, and the leather is prevented from blocking the grease and debris below and being unable to float up, thereby facilitating the subsequent filtering and the collection of impurities after filtration. Second, it can ensure that the leather is uniformly absorbed during the immersion process, and the leather is prevented from being insufficiently absorbed in some areas due to the downward sedimentation of the leather under the action of gravity, thereby making the dry leather softer after absorbing water and becoming wet. Third, during the immersion process of the leather, the intermittent cyclic turning of the turning group enables the filtering group and the collecting group in the two filter boxes 4 to work intermittently during the turning and stirring process of the leather itself in the immersion process, thereby completing the collection and filtration under the conditions required by the leather itself, without the need for workers to filter multiple times and adding other processes.

[0050] When the leather is impregnated, the disassembly plate 35 can be removed by the bolt 34, and the grease and debris inside the collection tank 18 can be cleaned out. The limiting frame 33 below the frame plate 6 can block the leather below to prevent the leather from floating up and being in a position where it fits between the filter plate 8 and the bottom of the frame plate 6, thereby preventing blockage between the frame plate 6 and the filter plate 8 and affecting the normal filtration.

[0051] The flipping group includes a first driving group and a second driving group;

[0052] The first driving group includes a motor 21, the motor 21 is fixedly connected to the side wall of the support frame 1, the output shaft of the motor 21 is fixedly connected to the second gear 22, the second gear 22 is meshed with a gear ring 23, and the gear ring 23 is fixedly connected to the side wall of the bathtub 2;

[0053] The first drive group is used to provide power to the second drive group.

[0054] The second driving group includes a third gear 24 and two arcuate rack rods 31, the two arcuate rack rods 31 are fixedly connected to the bathtub 2, the third gear 24 is rotatably connected to the side wall of the support frame 1, the rotating shaft of the third gear 24 passes through the bathtub 2 and is fixedly connected to the stirring shaft 3, the third gear 24 is meshed with a second rack rod 25, the second rack rod 25 is slidably connected to the side wall of the support frame 1, a plurality of strong springs 26 are fixedly connected between the bottom end of the second rack rod 25 and the side wall of the support frame 1, a fourth gear 27 is meshed on the side of the second rack rod 25 away from the third gear 24, the fourth gear 27 is rotatably connected to the side wall of the support frame 1 and a chain 28 is transmission-connected to its rotating shaft, the bottom end of the chain 28 is transmission-connected to the fifth gear 29, the fifth gear 29 is rotatably connected to the side wall of the support frame 1, the top of the second rack rod 25 is fixedly connected to a push rod 30, a one-way damper 36 is arranged outside the push rod 30, and the one-way damper 36 is fixedly connected to the side wall of the support frame 1.

[0055] A limiting ring 32 is fixedly connected to the bathtub 2 , and the limiting ring 32 is embedded in the supporting frame 1 .

[0056] like Figure 1 Figure 2 and Fig.10 As shown:

[0057] When the bathtub 2 needs to be driven to rotate, the motor 21 is started, the motor 21 drives the second gear 22 to rotate, and then the second gear 22 drives the gear ring 23 to rotate, so that the bathtub 2 can rotate 180 degrees inside the support frame 1 through the limiting ring 32;

[0058] Before the bathtub 2 rotates, the push rod 14 has lifted the pull rod 13 and the baffle 19, and the push rod 30 is located below the push rod 14, so the push rod 14 is at the top, so the push rod 14 needs to be reset before the filter box 4 below rotates to the top;

[0059] During the rotation of the bathtub 2, the fifth gear 29 will mesh with the arc-shaped rack rod 31, and then the fourth gear 27 will be driven to rotate through the chain 28, and the fourth gear 27 will drive the second rack rod 25 to slide downward. During this process, the second rack rod 25 will gradually compress the strong spring 26, and during this process, the second rack rod 25 will quickly mesh with the third gear 24 and then drive the stirring shaft 3 to rotate rapidly. At this time, the stirring shaft 3 will drive the leather to rotate rapidly, which plays a role in turning the leather over and accelerating the hydrophobicity during the rapid rotation. When the push rod 30 slides downward along the one-way damper 36, when the fifth gear 29 is disengaged from the arc-shaped rack rod 31, the strong spring 26 is compressed to the limit, and then the bathtub 2 rotates 180 degrees, and then the strong spring 26 gives the second rack rod 25 an upward thrust at the bottom, but the one-way damper 36 restricts the push rod 30, so that the push rod 30 can only move upward slowly, and the stirring shaft 3 will also rotate slowly, thereby slowly turning over the leather, so that the grease and debris in different areas can float to the inside of the filter box 4, which is convenient for subsequent filtering;

[0060] After the stirring shaft 3 rotates for a certain period of time, the push rod 30 will rise to a position where it contacts the lower arc-shaped end of the push rod 14 and slowly lifts the push rod 14, so that the push rod 14 can drive the pull rod 13 and the baffle 19 to rise, and then carry out subsequent filtering and collection work.
