Description

Technical Field

[0001] This invention relates to the field of leather preparation technology, and in particular to a convenient and easy-to-clean degreasing device for leather preparation. Background Technology

[0002] In the leather manufacturing process, raw hides need to undergo a series of complex chemical and mechanical treatments, with degreasing being one of the most crucial preliminary steps. Raw hides, especially pigskin and sheepskin, contain a large amount of natural oils. If these oils are not removed, they will seriously affect the penetration and bonding of chemical agents in subsequent processes such as tanning, dyeing, and fatliquoring, leading to quality problems in the finished leather, such as a stiff feel, uneven coloring, color differences, and even coating peeling.

[0003] Currently, the industry commonly uses rotary drums or specialized degreasing equipment to degrease leather. During operation, raw hides are added to the equipment along with degreasing agents, auxiliaries, and water. Mechanical stirring ensures that the degreasing agent comes into full contact with the raw hides, removing grease through emulsification, saponification, or hydrolysis.

[0004] However, existing degreasing equipment treats degreasing and equipment cleaning as two separate processes. After degreasing, the waste liquid needs to be drained, and then clean water and cleaning agents need to be re-injected before the equipment can be restarted for cleaning. The entire process requires multiple manual interventions, and the switching process is cumbersome, leading to low production efficiency. The reduction is accompanied by a significant increase in the consumption of water resources and cleaning agents. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that in existing degreasing equipment, degreasing and equipment cleaning are two separate processes. After degreasing, the waste liquid needs to be drained, and then clean water and cleaning agent need to be injected again before the equipment is restarted for cleaning. The whole process requires multiple manual interventions, the switching process is cumbersome, resulting in reduced production efficiency and high consumption of water and cleaning agents. Therefore, this invention proposes a convenient and easy-to-clean degreasing equipment for leather preparation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A convenient and easy-to-clean degreasing device for leather preparation includes a box body with an open top and a cover plate. A cleaning agent box is fixedly installed on the top of the cover plate, and a degreasing agent box is installed on the top of the cleaning agent box. Both the cleaning agent box and the degreasing agent box have inlet pipes installed on one side. A drive shaft is rotatably connected to the bottom inner wall of the box body. A rotating tube is slidably sleeved on the outside of the drive shaft, and multiple stirring rods are fixedly installed on the outside of the rotating tube. A drain pipe is installed on one side of the box body, and a valve is provided on the drain pipe. The liquid injection mechanism includes a liquid injection box, which is rotatably mounted on the top inner side of the cover plate. Multiple nozzles are installed at the bottom of the liquid injection box, and the nozzles are in communication with the liquid injection box. The wall scraping cleaning mechanism includes two support rods, which are fixedly installed on both sides of the drive shaft. A top rod is slidably connected to the side of the two support rods that is far apart from each other. A connecting block is fixedly installed at the end of the two top rods that is far apart from each other. A scraper is rotatably connected to the connecting block, and the scraper contacts and engages with the inner wall of the box.

[0007] Preferably, the liquid injection mechanism further includes a vertical tube, which is slidably installed on the cleaning agent tank and the degreasing agent tank. A connecting tube is fixedly installed on the top of the liquid injection box, and the vertical tube is sleeved on the outside of the connecting tube, and the connecting tube and the vertical tube are interconnected.

[0008] Preferably, both the cleaning agent tank and the degreasing agent tank have guide holes at their bottoms, and the two guide holes are slidably connected to the vertical pipe. Furthermore, both sides of the vertical pipe have connection holes that cooperate with the guide holes on the degreasing agent tank.

[0009] Preferably, a mounting bracket is fixedly installed on the top of the degreasing agent tank, and a cylinder is fixedly installed on the top of the mounting bracket, with the piston of the cylinder fixedly connected to the top of the vertical pipe.

[0010] Preferably, the wall scraping cleaning mechanism further includes a push plate, which is rotatably installed at the bottom end of the vertical pipe. Both sides of the push plate are rotatably connected to hinge rods, which are rotatably connected to the corresponding scrapers. Limiting holes are provided on the support rods, and the hinge rods are located in the limiting holes.

[0011] Preferably, each of the two support rods has a sliding groove on the side away from each other, the sliding groove is slidably connected to the corresponding top rod, and a top spring is fixedly installed on the inner wall of one side of the sliding groove, one end of the top spring is fixedly connected to the corresponding top rod.

[0012] Preferably, a diamond-shaped rod is fixedly installed at the bottom of the injection box, and a sleeve is slidably connected to the bottom end of the diamond-shaped rod. The same return spring is fixedly installed between the injection box and the sleeve. Limiting blocks are opened on both sides of the inner wall of the sleeve, and limiting grooves are opened on both sides of the top end of the drive shaft. The limiting grooves are slidably connected to the corresponding limiting blocks. A wedge-shaped washer is fixedly installed on the bottom inner wall of the box, and a wedge-shaped surface is provided at the bottom end of the rotating tube. The wedge-shaped washer and the wedge-shaped surface push together, so that the entire cover assembly (including the injection mechanism) can be easily separated from the main box, which greatly facilitates the deep cleaning, maintenance and component replacement of the equipment. The nozzle rotates with the drive shaft, and the sprayed liquid can cover a wider area under the action of centrifugal force and form strong convection with the material near the inner wall of the box. This mechanism makes the degreasing agent contact the leather more fully and mix more evenly, thereby improving the degreasing efficiency and effect.

[0013] Preferably, the nozzle outlet is located at a downward angle of 30 degrees from the tangent of the injection box. This 30-degree angled nozzle outlet design allows the cleaning agent or degreaser to be sprayed directly and powerfully onto the inner wall of the box, forming a synergistic "spray-scrape" cleaning effect with the wall scraping action. This ensures thorough cleaning without any blind spots and avoids the residue problems commonly found in traditional equipment.

[0014] Preferably, a motor is fixedly installed on one side of the housing, a drive rod is fixedly installed on the output shaft of the motor, a worm is fixedly installed on the drive rod, and a worm wheel is fixedly installed at the bottom of the drive shaft. The worm and the worm wheel mesh with each other, adopting a worm gear transmission method, which has the advantages of smooth transmission, low noise, and good self-locking (preventing the stirring shaft from reversing under load). At the same time, it can provide a large torque, which is sufficient to drive the stirring and scraping mechanism, and can operate stably even under heavy load.

[0015] Preferably, a fixed box is fixedly installed at the bottom of the housing. The fixed box is rotatably connected to the drive rod, and both the worm and the worm wheel are located inside the fixed box. Enclosing the worm and the worm wheel inside the fixed box can prevent leather fragments, hair, and other debris from getting caught, protect the transmission components, and extend the service life of the equipment.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The vertical pipe is connected to the degreasing agent tank and the cleaning agent tank through the connection hole. When the vertical pipe moves up and down, it can automatically switch between degreasing and cleaning. When switching, it can automatically drive the scraper to expand or retract, which facilitates the cleaning of the tank. 2. The scraper is always in close contact with the inner wall of the chamber through the top spring and rotates under the drive of the drive shaft. It can effectively scrape off the sebum, dirt and residual chemicals attached to the inner wall. At the same time, the design of the nozzle outlet is 30 degrees deflected, so that the cleaning agent or degreaser can be sprayed directly and powerfully onto the inner wall of the chamber. This, together with the scraping action, forms a "spray-scrape" synergistic cleaning effect, ensuring that there are no dead corners in the cleaning and avoiding the residue problems common in traditional equipment. 3. The nozzle rotates together with the drive shaft, allowing the sprayed liquid to cover a wider area under centrifugal force and creating strong convection with the materials near the inner wall of the chamber. This mechanism ensures more thorough contact and more uniform mixing of the degreasing agent with the leather, thereby improving degreasing efficiency and effectiveness.

[0017] This invention effectively solves the problems of inconvenient cleaning, uneven mixing, and unsanitary corners in traditional leather degreasing equipment through its integrated design, automated mode switching, dynamic wall scraping cleaning, and efficient mixing and spraying system. It not only significantly improves the efficiency and quality of degreasing operations, but also greatly reduces the labor intensity of manual cleaning and the difficulty of equipment maintenance. It is an innovative device that combines high performance and high convenience, and is very suitable for promotion and application in the modern leather processing industry.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Example, refer to Figure 1-8 A convenient and easy-to-clean degreasing device for leather preparation includes a box body 1, the top of the box body 1 is open and a cover plate 2 is installed on the top of the box body 1, a cleaning agent box 6 is fixedly installed on the top of the cover plate 2, a degreasing agent box 7 is installed on the top of the cleaning agent box 6, and an inlet pipe 8 is installed on one side of both the cleaning agent box 6 and the degreasing agent box 7. A drive shaft 3 is rotatably connected to the bottom inner wall of the box body 1, a rotating pipe 19 is slidably sleeved on the outside of the drive shaft 3, and a plurality of stirring rods 12 are fixedly installed on the outside of the rotating pipe 19. A drain pipe 18 is installed on one side of the box body 1, and a valve is provided on the drain pipe 18. The liquid injection mechanism 4 includes a liquid injection box 41, which is rotatably installed on the top inner side of the cover plate 2. Multiple nozzles 42 are installed at the bottom of the liquid injection box 41, and the nozzles 42 are in communication with the liquid injection box 41. The wall scraping cleaning mechanism 5 includes two support rods 51, which are respectively fixedly installed on both sides of the drive shaft 3. The two support rods 51 are slidably connected to the side of each other that is far apart from each other. The two top rods 52 are fixedly installed to the ends of each other that are far apart from each other. A scraper 54 is rotatably connected to the connecting block 53. The scraper 54 contacts and cooperates with the inner wall of the box 1.

[0023] Furthermore, the injection mechanism 4 also includes a vertical tube 44, which is slidably installed on the cleaning agent tank 6 and the degreasing agent tank 7. A connecting tube 43 is fixedly installed on the top of the injection box 41. The vertical tube 44 is sleeved on the outside of the connecting tube 43, and the connecting tube 43 and the vertical tube 44 are interconnected. Guide holes 48 are opened at the bottom of both the cleaning agent tank 6 and the degreasing agent tank 7. The two guide holes 48 are slidably connected to the vertical tube 44. Connecting holes 45 are opened on both sides of the vertical tube 44. The connecting holes 45 cooperate with the guide holes 48 on the degreasing agent tank 7. A mounting bracket 46 is fixedly installed on the top of the degreasing agent tank 7. A cylinder 47 is fixedly installed on the top of the mounting bracket 46. The piston of the cylinder 47 is fixedly connected to the top of the vertical tube 44.

[0024] The degreasing agent in the degreasing agent tank 7 is introduced into the vertical pipe 44 through the connecting hole 45, and then into the liquid injection box 41 through the connecting pipe 43. Finally, it is sprayed out through the nozzle 42. At the same time, the guide hole 48 is equipped with a sealing structure, which fits together with the vertical pipe 44 to form a sealing structure, so that the liquid in the degreasing agent tank 7 and the cleaning agent tank 6 will not leak out. When the vertical pipe 44 moves up and down, it drives the connecting hole 45 on the vertical pipe 44 to switch between the degreasing agent tank 7 and the cleaning agent tank 6, so that the liquid in the degreasing agent tank 7 and the cleaning agent tank 6 can be used for different functions.

[0025] A further advantage of the above is that the wall scraping cleaning mechanism 5 also includes a push plate 55, which is rotatably installed at the bottom end of the vertical pipe 44. Both sides of the push plate 55 are rotatably connected to hinge rods 56, which are rotatably connected to the corresponding scraper 54. The support rod 51 has a limit hole 57, and the hinge rod 56 is located in the limit hole 57. The two support rods 51 are provided with sliding grooves 58 on the side away from each other. The sliding grooves 58 are slidably connected to the corresponding top rods 52. A top spring 59 is fixedly installed on the inner wall of one side of the sliding groove 58, and one end of the top spring 59 is fixedly connected to the corresponding top rod 52.

[0026] The vertical tube 44, which moves up and down, drives the push plate 55 to move. The push plate 55 pushes the scraper 54 to change angle through the hinge rod 56. At the same time, the top rod 52 is slidably connected with the sliding groove 58, so that the top rod 52 can extend and retract left and right under the limit of the sliding groove 58. Under the action of the top spring 59, it pushes against the inner wall of the box 1, thereby causing the scraper 54 to fit against the inner wall of the box 1. When the support rod 51 rotates, it can drive the scraper 54 to scrape and clean the inner wall of the box 1.

[0027] Furthermore: A rhomboid rod 513 is fixedly installed at the bottom of the injection box 41, and a sleeve 9 is slidably connected to the bottom end of the rhomboid rod 513. The same return spring 514 is fixedly installed between the injection box 41 and the sleeve 9. Limiting blocks 11 are opened on both sides of the inner wall of the sleeve 9. Limiting grooves 10 are opened on both sides of the top end of the drive shaft 3. The limiting grooves 10 are slidably connected to the corresponding limiting blocks 11. A wedge-shaped washer 511 is fixedly installed on the bottom inner wall of the box 1. A wedge-shaped surface 512 is provided at the bottom end of the rotating tube 19. The wedge-shaped washer 511 and the wedge-shaped surface 512 push and cooperate.

[0028] The sleeve 9 is slidably connected to the drive shaft 3, allowing for easy disassembly and installation between the sleeve 9 and the drive shaft 3, facilitating the removal of the cover plate 2. Simultaneously, the sliding connection between the limiting groove 10 and the limiting block 11 allows the rotating drive shaft 3 to drive the nozzle 42 to rotate via the sleeve 9, causing the liquid inside the nozzle 42 to be quickly drawn out of the injection box 41 under centrifugal force, preventing discontinuity. Furthermore, the sliding connection between the rhomboid rod 513 and the sleeve 9 allows the sleeve 9 to move up and down, and to be pushed downwards by the return spring 514. Simultaneously, when the drive shaft 3 rotates, it drives the rotating tube 19 to rotate. The rotation of the rotating tube 19, through the pushing action of the wedge-shaped washer ring 511 and the wedge-shaped surface 512, allows the rotating tube 19 to move up and down, thereby causing the scraper 54 on the sleeve 9 to move downwards. This allows for up-and-down shaking during the rotating scraping operation, increasing friction with the inner wall, resulting in better cleaning and preventing grease from sticking to the inner wall of the housing 1.

[0029] Furthermore, the outlet of the nozzle 42 is located at the tangent of the injection box 41 and is tilted downwards by thirty degrees.

[0030] By setting the outlet of the nozzle 42 at a 30-degree angle, the liquid sprayed from the nozzle 42 can directly act on the inner wall of the box 1, which facilitates cleaning with detergent and also facilitates contact between the degreasing agent and the animal skin fat inside the box 1.

[0031] A motor 13 is fixedly installed on one side of the housing 1. A drive rod 14 is fixedly installed on the output shaft of the motor 13. A worm gear 15 is fixedly installed on the drive rod 14. A worm wheel 16 is fixedly installed at the bottom of the drive shaft 3. The worm gear 15 and the worm wheel 16 mesh with each other. A fixed box 17 is fixedly installed at the bottom of the housing 1. The fixed box 17 is rotatably connected to the drive rod 14, and both the worm gear 15 and the worm wheel 16 are located inside the fixed box 17.

[0032] The output shaft of motor 13 drives drive rod 14 to rotate. Drive rod 14, through the meshing of worm 15 and worm wheel 16, can drive drive shaft 3 to rotate and increase the rotational torque of drive shaft 3. This increases the mixing and degreasing of degreasing agent and sebum in the box 1 through stirring rod 12. The fixed box 17 can isolate worm 15 and worm wheel 16 and ensure stable transmission between worm 15 and worm wheel 16.

[0033] When using this invention, the motor 13 switch is turned on, and the output shaft of the motor 13 drives the drive rod 14 to rotate. The drive rod 14, through the meshing of the worm gear 15 and the worm wheel 16, drives the drive shaft 3 to rotate. When the rotating tube 19 rotates, the wedge-shaped washer 511 and the wedge-shaped surface 512 push against each other, thereby driving the rotating tube 19 to move up and down. This allows the stirring rod 12 to vibrate up and down when it rotates, making the mixing more thorough. The stirring rod 12 increases the mixing and degreasing of the degreasing agent and sebum in the box 1. At the same time, the sleeve 9 is slidably connected to the drive shaft 3, allowing the sleeve 9 to connect with the drive shaft 3. The shafts 3 are disassembled and installed to facilitate the removal of the cover plate 2. The degreasing agent in the degreasing agent tank 7 is introduced into the vertical pipe 44 through the connecting hole 45 on the vertical pipe 44, and then into the injection box 41 through the connecting pipe 43. Finally, it is sprayed out through the nozzle 42. At the same time, the sliding connection between the limiting groove 10 and the limiting block 11 allows the rotating drive shaft 3 to drive the nozzle 42 to rotate through the sleeve 9. This causes the liquid in the nozzle 42 to be quickly drawn out of the injection box 41 under the action of centrifugal force, which facilitates the injection of degreasing agent or cleaning agent. When it is necessary to clean the inside of the tank 1, the vertical pipe is pushed by the cylinder 47. The vertical tube 44 moves downward, and the connecting hole 45 on the vertical tube 44 moves up and down to switch between the degreasing agent tank 7 and the cleaning agent tank 6, so that the connecting hole 45 moves from the degreasing agent tank 7 to the cleaning agent tank 6, injecting the cleaning agent in the cleaning agent tank 6 and acting on the inner wall of the tank body 1 through the nozzle 42. The vertical tube 44 moves up and down, driving the push plate 55 to move. The push plate 55 pushes the scraper 54 to change angle through the hinge rod 56. At the same time, the top rod 52 is slidably connected to the sliding groove 58, so that the top rod 52 can extend and retract left and right under the limit of the sliding groove 58, and pushes under the action of the top spring 59. Pushing it against the inner wall of the housing 1 causes the scraper 54 to come into contact with the inner wall of the housing 1. When the support rod 51 rotates, it can drive the scraper 54 to scrape and clean the inner wall of the housing 1. The rotating tube 19 moves up and down, causing the scraper 54 on the sleeve 9 to move downward, so that it can perform up and down shaking operation when rotating and scraping the wall, increasing the friction effect with the inner wall, making the cleaning effect better and preventing grease from sticking to the inner wall of the housing 1. The liquid inlet pipe 8 can facilitate the replenishment of the degreasing agent tank 7 and the cleaning agent tank 6. The drain pipe 18 can facilitate the discharge and replacement of wastewater in the housing 1.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
