Description

Technical Field

[0001] This invention belongs to the field of leather production and processing technology, specifically relating to a dust removal device for processing leather and its leather dust removal process. Background Technology

[0002] Leather is a durable material made from animal skin through tanning and processing. It is soft, tough, and breathable, and is widely used in clothing, footwear, handbags, furniture, and automotive interiors. The leather-making process typically includes peeling, dehairing, tanning, and dyeing. With technological advancements, modern leather goods incorporate various decorative and functional designs, enhancing both their aesthetics and practicality. In addition to traditional natural leather, synthetic leather and other alternatives now have a place in the market, providing new options for environmental protection and cost considerations.

[0003] Before other processing operations, leather needs to be dusted to ensure that the overall processing quality is not affected in subsequent processing. However, existing dust removal devices for leather processing are prone to deformation when the leather is squeezed during transportation, which may cause wrinkles. In addition, different types of leather have different textures, making it impossible to completely remove dust. Furthermore, dust removal devices generally use brush rollers for dust removal, but the brush rollers cannot be adjusted during use, and the distance between the leather and the brush rollers cannot be controlled. As a result, the leather cannot make full contact with the brush rollers during dust removal, leading to incomplete dust removal. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dust removal device and a leather dust removal process for processing leather.

[0005] The technical solution adopted to solve the above technical problems is: a dust removal device for processing leather, including a main body, a base frame fixedly connected to the bottom of the main body, and a control console provided on the top of the main body;

[0006] Transmission mechanisms are installed on both sides of the main body, and adjustment mechanisms are installed inside the main body;

[0007] Two dust removal mechanisms are installed on one side inside the adjustment mechanism, and multiple air knife mechanisms are installed inside each of the two dust removal mechanisms.

[0008] Preferably, the transmission mechanism includes two fixed plates fixedly connected to one side of the main body, one of the fixed plates is fixedly connected to a first motor at its front end, the output end of the first motor is fixedly connected to a conveyor roller, the outer wall of the conveyor roller is rotatably connected to a conveyor belt, and two conveyor rollers are provided between the two fixed plates.

[0009] With the above technical solution, when using the leather to be dusted, after the leather is prepared, it can be transported to the main body using a conveyor mechanism. Before dusting, it can be transported through one of the conveyor mechanisms. After dusting, it can be transported out using another conveyor mechanism, thus forming a processing production line. Specifically, the leather to be processed is laid flat on the conveyor belt between two fixed plates located on one side of the main body. Then, the first motor is started to drive the conveyor roller at the output end to rotate. Subsequently, the conveyor belt will move until the leather moves into the main body.

[0010] Preferably, the adjusting mechanism includes two hydraulic cylinders rotatably connected to the front end of the main body. Each of the piston ends of the two hydraulic cylinders is rotatably connected to a support plate. A fixed shaft is fixedly connected to the middle of each of the two support plates. Multiple arc-shaped grooves are provided at the front and rear ends of the main body. A second motor is fixedly connected to the front end of the main body. A first gear is fixedly connected to the outer wall of the output shaft of the second motor. Two first connecting rods are rotatably connected to the front and rear ends of the outer wall of the fixed shaft. A second gear is rotatably connected to the other end of each of the two first connecting rods. A second connecting rod is rotatably connected to one side of each of the two second gears. A third gear is rotatably connected to the other end of each of the two second connecting rods. A third connecting rod is rotatably connected to one side of each of the two third gears. The interiors of the multiple arc-shaped grooves are slidably connected to the corresponding fixed shafts. The outer wall of the output shaft of the second motor is rotatably connected to the support plate.

[0011] Through the above technical solution, when the leather enters the dust removal area, the adjustable mechanism can clamp the leather from top to bottom, allowing for selection based on the leather's thickness. This maintains the leather in a taut state, ensuring clear grain and preventing impurities from accumulating during dust removal. Furthermore, the upper and lower structure enables double-sided dust removal of the leather. The difference between the leather conveying speed and the dust removal speed allows for repeated dust removal of the same area, maximizing dust removal efficiency. The differential speed design ensures uniform movement of the brush rollers on the leather surface, avoiding incomplete or over-cleaning in certain areas and ensuring consistent cleaning results. Specifically… The piston ends of the two hydraulic cylinders are activated, extending upwards until the support plate is lifted, causing the support plate to move in a semi-circular motion around the output shaft of the second motor until the fixed shaft is pushed upwards. When multiple pressing rollers press the leather tightly, the pushing operation stops. At this point, the leather is straightened, making cleaning easier and more efficient. Then, the second motor is activated, driving the first gear of the output shaft to rotate. At this time, it needs to cooperate with other mechanisms to move. Simultaneously, under the connection of the first, second, and third connecting rods and the meshing of the second and third gears, the upper and lower rollers can maintain a consistent degree of pressing and the leather can be transferred to one side. The thickness can be adjusted while rotating.

[0012] Preferably, the dust removal mechanism includes two gear bodies rotatably connected to the front and rear ends of the outer wall of a fixed shaft. Multiple guide posts are fixedly connected to opposite sides of each of the two gear bodies. Fixed frames are fixedly connected to the front and rear ends of the outer wall of the fixed shaft. Multiple fourth gears are rotatably connected to opposite sides of each of the two fixed frames. Pressure rollers mesh with the outer walls of the multiple fourth gears. A dust removal roller is rotatably connected between the two fourth gears. A cylinder is fixedly connected to the outer wall of the fixed shaft. An arc-shaped closed groove is provided on the outer wall of the cylinder. Multiple bristles are fixedly connected to the outer wall of the dust removal roller. One of the gear bodies meshes with a first gear. The multiple guide posts are slidably connected to the front and rear ends of the dust removal roller, respectively. The arc-shaped closed groove is slidably connected to a limiting rod on one side of the inner wall of the dust removal roller.

[0013] Through the above technical solution, while the leather is being conveyed, the adjustment mechanism and dust removal mechanism work together to clean the leather. During the cleaning rotation, the brush can move back and forth, allowing for both rotary cleaning and lateral dust removal. With this lateral movement, the dust removal brush adjusts its contact with the leather surface to better adapt to different leather textures and surface conditions. Specifically, multiple pressure rollers press the leather together, and the first gear, in conjunction with the gear body, drives the gear body to rotate, subsequently rotating the fourth gears on multiple fixed frames. When the gear body meshes with the fourth gear, it drives the pressure roller to rotate. At this time, the diameter of the pressure roller located on the outer ring is larger than the rotation diameter of the inner gear body. Consequently, the rotation speed of the dust removal roller is greater than that of the pressure roller, allowing the leather to undergo multiple dust removal operations while moving in the same area. Simultaneously, under the limit of the guide post on the opposite side of the multiple gear bodies, the corresponding dust removal roller will be driven to rotate. At this time, the limiting shaft on the inner wall of the dust removal roller will slide along the arc-shaped closed groove on the outer wall of the cylinder, allowing the dust removal roller to move back and forth on the fixed shaft. This allows the leather to be cleaned at different angles in the same position, resulting in a cleaner leather.

[0014] Preferably, the air knife mechanism includes a fixed frame fixedly connected to the other side of the inner wall of the dust removal roller, a fan fixedly connected to the bottom of the fixed frame, an air inlet pipe fixedly connected to the rear end of the fan, a T-junction provided at the front end of the fan, multiple branch pipes fixedly connected to the output end of the T-junction, multiple fixing strips fixedly connected to the outer wall of the dust removal roller, multiple air vents provided at the top of the multiple fixing strips, and the fixing strips and brush bristles are distributed alternately on the outer wall of the dust removal roller.

[0015] Through the above technical solution, under the operation of the dust removal mechanism, the air knife mechanism, with multiple brush bristles arranged in an alternating pattern, can rotate and move simultaneously. The airflow from the air knife combines with the physical friction of the brush bristles, using airflow to blow away loose dust from the surface and physical contact with the brush rollers to remove tightly attached impurities. The synergistic effect of both ensures a more thorough and uniform cleaning. Specifically, as the dust removal rollers rotate, multiple fans can be activated. Airflow then enters through multiple inlet pipes, passes through tee fittings, and is transmitted through multiple branch pipes to the corresponding fixed strips. Subsequently, air is blown onto the leather from multiple air outlets, allowing the gas to be blown onto the leather from different angles, ensuring thorough cleaning of the dust on the leather.

[0016] A leather dust removal process for processing leather includes the following steps:

[0017] Step 1: Lay the leather to be processed flat on the conveyor belt between two fixed plates on one side of the main body. Then start the first motor to drive the conveyor roller at the output end to rotate. The conveyor belt will then move, thereby moving the leather to one side and delivering it to the dust removal area.

[0018] Step 2: After the leather moves into the interior of the main body, the piston ends of the two hydraulic cylinders can be activated to extend upward until the support plate is lifted, so that the support plate moves in a semi-circular motion around the output shaft of the second motor until the fixed shaft is pushed upward. When the multiple pressing rollers press the leather, the pushing operation stops.

[0019] Step 3: At this time, multiple fans located on the other side of the inner wall of the dust removal roller can be started. Then the airflow will enter from multiple air inlet pipes, pass through the tee and be transmitted from multiple branch pipes to the corresponding fixed strips. Then it will be started to blow air onto the leather from multiple air outlets.

[0020] Step 4: The second motor is then started, which drives the first gear on the output shaft to rotate. Due to the interaction between the first gear and the gear body, the gear body will rotate, which in turn will drive the fourth gear on the multiple fixed frames to rotate. With the connection of the first, second, and third connecting rods and the meshing of the second and third gears, the multiple pressing rollers located above and below will rotate, allowing the leather to be conveyed. At the same time, under the limit of the guide post on the opposite side of the multiple gear bodies, the corresponding dust removal roller will rotate. At this time, the limiting shaft on the inner wall of the dust removal roller will slide along the arc-shaped closed groove on the outer wall of the cylinder, allowing the dust removal roller to move back and forth on the fixed shaft, so that the multiple bristles and multiple air vents on the multiple fixed strips can also move while rotating.

[0021] Step 5: The dust-removed leather will be conveyed until it moves to the conveyor belt on the other side of the main body. Then, the first motor on the other side will be started to drive the conveyor belt to transport the leather out. At this point, the leather dust removal work is completed.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) By designing a transmission mechanism, adjustment mechanism, dust removal mechanism and air knife mechanism, the present invention can allow the leather to be stretched and dusted after entering, and can be adjusted according to the thickness of the leather to ensure the applicability of the dust removal device. At the same time, by using the differential speed of the pressure roller and the dust removal roller and the alternation of the brush bristles and the air knife, the leather can be thoroughly cleaned. In addition, it can also move while rotating for dust removal, so that the leather can be absolutely cleaned.

[0024] (2) The present invention can be conveyed to the dust removal position when the leather is being dusted through the transmission mechanism and the adjustment mechanism. At the same time, it can be clamped and straightened according to the thickness of the leather, which helps to eliminate these wrinkles, ensures that the leather surface is flat, and makes it easier to remove dust and impurities attached to the surface.

[0025] (3) By designing a dust removal mechanism and an air knife mechanism, this invention can utilize the speed difference between the leather conveying and the dust removal roller during the dust removal process. The multiple rotations of the brush roller can ensure that the dust and impurities on the leather surface are removed more thoroughly, avoiding insufficient cleaning in a single cleaning. Furthermore, the brush bristles and air knife are arranged in an alternating manner, and the cross distribution of the brush bristles and air knife can cover all corners of the leather surface, forming a multi-angle dust removal effect. In addition, the brush bristles and air knife can also move laterally back and forth while rotating to remove dust, so that every part of the leather surface can be subjected to the action of the brush roller and air knife multiple times, without any omissions or dead corners, thereby greatly improving the dust removal efficiency.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] like Figures 1-8 As shown, this embodiment of a dust removal device for processing leather includes a main body 1, a base frame 2 fixedly connected to the bottom of the main body 1, a control console 3 on the top of the main body 1, and a transmission mechanism 4 installed on both sides of the main body 1. The transmission mechanism 4 includes two fixed plates 401 fixedly connected to one side of the main body 1. A first motor 402 is fixedly connected to the front end of one of the fixed plates 401, and a conveyor roller 403 is fixedly connected to the output end of the first motor 402. A conveyor belt 404 is rotatably connected to the outer wall of the conveyor roller 403. Two conveyor rollers 403 are provided between the two fixed plates 401. After the leather to be dusted is prepared, it can be transported to the main body 1 using the conveyor mechanism 4. Before dusting, it can be transported through one of the conveyor mechanisms 4. After dusting, it can be transported out using the other conveyor mechanism 4, thus forming a processing production line. Specifically, the leather to be processed is laid flat on the conveyor belt 404 between two fixed plates 401 located on one side of the main body 1. Then, the first motor 402 is started to drive the conveyor roller 403 at the output end to rotate. Then, the conveyor belt 404 will move until the leather moves into the main body 1.

[0037] like Figures 4-5As shown, an adjustment mechanism 5 is installed inside the main body 1. The adjustment mechanism 5 includes two hydraulic cylinders 501 rotatably connected to the front end of the main body 1. Each of the piston ends of the two hydraulic cylinders 501 is rotatably connected to a support plate 502. Each of the two support plates 502 is fixedly connected to a fixed shaft 503 at its middle end. The front and rear ends of the main body 1 are provided with multiple arc-shaped grooves 504. A second motor 505 is fixedly connected to the front end of the main body 1. A first gear 506 is fixedly connected to the outer wall of the output shaft of the second motor 505. Two first connecting rods 507 are rotatably connected to the front and rear ends of the outer wall of the fixed shaft 503. The other ends of the two first connecting rods 507 are rotatably connected to a first gear 506. Two gears 508 are rotatably connected to a second connecting rod 509 on one side, and a third gear 510 is rotatably connected to the other end of each of the two second connecting rods 509. A third connecting rod 511 is rotatably connected to one side of each of the two third gears 510. Multiple arc-shaped grooves 504 are slidably connected to corresponding fixed shafts 503. The outer wall of the output shaft of the second motor 505 is rotatably connected to a support plate 502. When the leather enters the dust removal area, the adjusting mechanism 5 can be used to clamp the leather vertically, allowing for selection based on the leather thickness and maintaining a taut state. When dusting, the texture of the leather remains clear, making it less prone to accumulating impurities. Furthermore, the upper and lower structure allows for double-sided dust removal of the leather. Simultaneously, the difference in speed between the leather conveying and dust removal allows for repeated dust removal of the same area, maximizing dust removal efficiency. The differential speed design ensures uniform movement of the brush rollers on the leather surface, avoiding incomplete or over-cleaning in certain areas and ensuring consistent cleaning results. Specifically, activating the pistons of two hydraulic cylinders 501 extends upwards until the support plate 502 is lifted, causing the support plate 502 to form a semi-circle around the output shaft of the second motor 505. The movement continues until the fixed shaft 503 is pushed upward. When multiple pressing rollers 605 press the leather tightly, the pushing operation stops. At this time, the leather is straightened, making cleaning easier and more efficient. Then, the second motor 505 is started, which drives the first gear 506 of the output shaft to rotate. At this time, it needs to cooperate with other mechanisms to move. Simultaneously, under the connection of the first connecting rod 507, the second connecting rod 509 and the third connecting rod 511, and the meshing of the second gear 508 and the third gear 510, the upper and lower rollers can maintain a consistent degree of pressing and the leather can be transferred to one side. It can also rotate while adjusting the thickness.

[0038] like Figures 5-7As shown, two dust removal mechanisms 6 are installed on one side inside the adjusting mechanism 5. Each dust removal mechanism 6 includes two gear bodies 601 rotatably connected to the front and rear ends of the outer wall of the fixed shaft 503. Multiple guide posts 602 are fixedly connected to opposite sides of each gear body 601. Fixed frames 603 are fixedly connected to the front and rear ends of the outer wall of the fixed shaft 503. Multiple fourth gears 604 are rotatably connected to opposite sides of each fixed frame 603. Pressure rollers 605 mesh with the outer walls of each of the multiple fourth gears 604. A dust removal roller 606 is rotatably connected between two fourth gears 604. The outer wall of the fixed shaft 503 is fixedly connected to... A cylindrical component 607 has an arc-shaped closed groove 608 on its outer wall. Multiple brush bristles 609 are fixedly connected to the outer wall of a dust removal roller 606. One gear body 601 meshes with a first gear 506. Multiple guide posts 602 are slidably connected to the front and rear ends of the dust removal roller 606. The arc-shaped closed groove 608 is slidably connected to a limiting rod on one side of the inner wall of the dust removal roller 606. While the leather is being conveyed, the adjustment mechanism 5 and the dust removal mechanism 6 work together to clean the leather. Furthermore, the cleaning mechanism allows the leather to move back and forth during rotation, thus enabling not only rotational cleaning but also... Lateral dust removal: As the brush moves laterally, it adjusts its contact with the leather surface to better adapt to different leather textures and surface conditions. Specifically, multiple pressure rollers 605 press the leather, and due to the engagement of the first gear 506 and gear body 601, the gear body 601 rotates, subsequently driving the fourth gear 604 on multiple fixed brackets 603 to rotate. Utilizing the meshing of the gear body 601 and the fourth gear 604, the pressure rollers 605 rotate. At this time, the diameter of the outer pressure roller 605 is larger than that of the inner gear body 601. The rotation diameter of the 1-axis means that the rotation speed of the dust removal roller 606 is greater than that of the pressure roller 605, allowing the leather to undergo multiple dust removal operations while moving in the same area. At the same time, under the limit of the guide post 602 on the opposite side of the multiple gear bodies 601, the corresponding dust removal roller 606 will be driven to rotate. At this time, the limiting shaft on the inner wall of the dust removal roller 606 will slide along the arc-shaped closed groove 608 on the outer wall of the cylinder 607, allowing the dust removal roller 606 to move back and forth on the fixed shaft 503, so that the leather can be cleaned at different angles in the same position, making the leather cleaner.

[0039] like Figure 6 and Figure 8As shown, both dust removal mechanisms 6 are equipped with multiple air knife mechanisms 7. Each air knife mechanism 7 includes a fixed frame 701 fixedly connected to the other side of the inner wall of the dust removal roller 606. A fan 702 is fixedly connected to the bottom of the fixed frame 701. An air inlet pipe 703 is fixedly connected to the rear end of the fan 702. A tee 704 is provided at the front end of the fan 702. Multiple branch pipes 705 are fixedly connected to the output end of the tee 704. Multiple fixing strips 706 are fixedly connected to the outer wall of the dust removal roller 606. Multiple air vents 707 are provided at the top of the multiple fixing strips 706. The fixing strips 706 and brush bristles 609 are staggered on the outer wall of the dust removal roller 606. When the dust removal mechanism 6 is running, the air knife mechanism 7 can rotate and move while the multiple brush bristles 609 are staggered. The airflow of the air knife and the physical friction of the brush bristles 609 are combined to blow away the loose dust on the surface and remove the tightly attached impurities through the physical contact of the brush roller. The two work together to ensure a more thorough and even cleaning. Specifically, as the dust removal roller 606 rotates, multiple fans 702 can be activated. Then, airflow will enter from multiple air inlets 703, pass through tee 704, and be transmitted from multiple branch pipes 705 to the corresponding fixing strips 706. Then, it will be activated to blow air onto the leather from multiple air outlets 707. The air can be blown onto the leather from different angles, so that the dust on the leather is fully cleaned.

[0040] A leather dust removal process for processing leather includes the following steps:

[0041] Step 1: Lay the leather to be processed flat on the conveyor belt 404 between the two fixed plates 401 on one side of the main body 1. Then start the first motor 402 to drive the conveyor roller 403 at the output end to rotate. Then the conveyor belt 404 will move, thereby moving the leather to one side and delivering it to the dust removal area.

[0042] Step 2: When the leather moves into the body 1, the piston ends of the two hydraulic cylinders 501 can be activated to extend upward until the support plate 502 is lifted, so that the support plate 502 moves in a semi-arc shape with the output shaft of the second motor 505 as the center until the fixed shaft 503 is pushed upward. When the multiple pressing rollers 605 press the leather, the pushing operation stops.

[0043] Step 3: At this time, multiple fans 702 located on the other side of the inner wall of the dust removal roller 606 can be started. Then the airflow will enter from multiple air inlet pipes 703, pass through the tee 704, and be transmitted from multiple branch pipes 705 to the corresponding fixing strip 706. Then the airflow will be blown towards the leather from multiple air outlets 707.

[0044] Step 4: Then, the second motor 505 is started, which drives the first gear 506 of the output shaft to rotate. Since the first gear 506 is in contact with the gear body 601, it will drive the gear body 601 to rotate. Then, it will drive the fourth gear 604 on the multiple fixed brackets 603 to rotate. Under the connection of the first connecting rod 507, the second connecting rod 509 and the third connecting rod 511, and under the meshing of the second gear 508 and the third gear 510, the multiple pressing rollers 605 located above and below will rotate, so that the leather can be conveyed. At the same time, under the limit of the guide post 602 on the opposite side of the multiple gear bodies 601, the corresponding dust removal roller 606 will be driven to rotate. At this time, the limiting shaft on the inner wall of the dust removal roller 606 will slide along the arc-shaped closed groove 608 on the outer wall of the cylinder 607, so that the dust removal roller 606 can move back and forth on the fixed shaft 503, so that the multiple bristles 609 and the multiple air vents 707 on the multiple fixed strips 706 can also move while rotating.

[0045] Step 5: The dust-removed leather will be conveyed until it moves to the conveyor belt 404 on the other side of the main body 1. Then, the first motor 402 on the other side will be started to drive the conveyor belt 404 to convey the leather until it is transported out. At this point, the leather dust removal work is completed.

3. The dust removal device for processing leather according to claim 2, characterized in that, Two conveying rollers (403) are provided between the two fixed plates (401).

4. The leather dust removal process of a dust removal device for processing leather according to claim 3, characterized in that, Includes the following steps: Step 1: Lay the leather to be processed flat on the conveyor belt (404) between the two fixed plates (401) on one side of the main body (1). Then start the first motor (402) to drive the conveyor roller (403) at the output end to rotate. Then the conveyor belt (404) will move, thereby driving the leather to move to one side and deliver it to the dust removal area. Step 2: When the leather moves into the body (1), the piston ends of the two hydraulic cylinders (501) can be activated to extend upward until the support plate (502) is lifted up, so that the support plate (502) moves in a semi-arc shape with the output shaft of the second motor (505) as the center until the fixed shaft (503) is pushed upward. When the multiple pressing rollers (605) press the leather, the pushing operation stops. Step 3: At this time, multiple fans (702) located on the other side of the inner wall of the dust removal roller (606) can be started. Then the airflow will enter from multiple air inlet pipes (703), pass through the tee (704), and be transmitted from multiple branch pipes (705) to the corresponding fixing strip (706). Then the airflow will blow onto the leather from multiple air outlets (707). Step 4: The second motor (505) is then started, which drives the first gear (506) on the output shaft to rotate. Since the first gear (506) is engaged with the gear body (601), it drives the gear body (601) to rotate, which in turn drives the fourth gear (604) on the multiple fixed brackets (603) to rotate. With the connection of the first connecting rod (507), the second connecting rod (509), and the third connecting rod (511), and the meshing of the second gear (508) and the third gear (510), the multiple pressing rollers (605) located above and below will... The rotation allows the leather to be conveyed. At the same time, under the limit of the guide post (602) on the opposite side of the multiple gear bodies (601), the corresponding dust removal roller (606) will be driven to rotate. At this time, the limiting shaft on the inner wall of the dust removal roller (606) will slide along the arc-shaped closed groove (608) on the outer wall of the cylinder (607), so that the dust removal roller (606) can move back and forth on the fixed shaft (503), so that the multiple bristles (609) and the multiple air vents (707) on the multiple fixed strips (706) can also move while rotating. Step 5: The dust-removed leather will be conveyed until it moves to the conveyor belt (404) on the other side of the main body (1). Then, the first motor (402) on the other side is started to drive the conveyor belt (404) to convey the leather until it is transported out. At this point, the leather dust removal work is completed.
