Description

Technical Field

[0001] This application relates to the field of fiber blending and processing, and in particular to a high-efficiency cotton blending bin for processing leather and fiber blends. Background Technology

[0002] In the production of leather and fiber fabrics, blending is a crucial step. As market demands for the quality and performance of leather and fiber fabrics continue to rise, blending technology is also constantly evolving. High-quality blends result in leather and fiber fabrics that excel in texture, strength, and breathability, meeting the diverse needs of different industries and consumers. For example, in the apparel industry, high-quality leather and fiber fabrics enhance comfort and aesthetics; in furniture décor, they add unique texture and style; and in automotive interiors, well-blended fabrics improve the overall quality and comfort of the vehicle. Today, blending technology has become a key factor determining the quality of leather and fiber fabrics. Its development level not only affects the quality and market competitiveness of leather and fiber fabric products but also has significant implications for the sustainable development of the entire leather and fiber industry. Advances in blending technology can promote the effective use of resources and drive related industries towards a more environmentally friendly and efficient direction. In existing fiber blending processes, the common practice is to simply mix various fibers together. Related technology discloses a fiber mixer, including a frame, a mixing tank mounted on the frame, a mixing assembly inside the mixing tank, and a drive assembly for driving the mixing assembly. The mixing assembly includes a mixing shaft connected to the drive assembly and spiral blades sleeved on the mixing shaft. The spiral blades include a straight mixing section and a conical mixing section, with the conical mixing section located below the straight mixing section. Multiple baffles are provided on the inner wall of the mixing tank to change the flow direction of the liquid within the tank. However, existing blending bin technology has significant drawbacks. On the one hand, for fiber blends containing many types of fibers, the single-step mixing method mentioned above makes it difficult to ensure thorough and uniform mixing of the various fibers. On the other hand, during the pre-processing stage of the blending bin, the fiber fabric is cut, resulting in a lot of fiber scrap waste. Existing fiber mixers can only mix the raw fiber material and cannot simultaneously mix the raw fiber material and the fiber scrap waste. Especially for high-quality leather and fiber fabrics with high production requirements, and for some high-end market high-quality leather and fiber fabrics, a high degree of mixing uniformity is required in the production process to obtain high-quality leather and fiber fabrics. The existing one-step mixing silo cannot meet this mixing uniformity requirement. Utility Model Content

[0003] In order to reduce fiber production costs, make reasonable use of fiber scraps and waste materials, avoid resource waste, improve the mixing uniformity of the blending bin, and obtain high-quality leather and fiber fabrics, this application provides a high-efficiency blending bin for leather and fiber blending processing.

[0004] The high-efficiency cotton blending bin for processing fiber blends provided in this application adopts the following technical solution:

[0005] A high-efficiency cotton blending bin for processing fiber blends includes a first mixing bin, a second mixing bin, a first stirring device, a second stirring device, and a feeding device. A first blower mechanism and a second blower mechanism are respectively installed in the first and second mixing bins. The first mixing bin is equipped with a raw material feeding mechanism, and the second mixing bin is equipped with a waste material feeding mechanism. A raw material distribution mechanism is provided between the first and second mixing bins to divert raw materials from the first mixing bin to the second mixing bin. The first stirring device includes a first housing, a first feeding mechanism, and a first stirring mechanism. The first housing is located directly below the first mixing bin, and the two are connected by the first feeding mechanism. The first mixing mechanism is located inside the first chamber and is used to mix the fiber raw materials. The feeding device is used to transfer the mixed fiber raw materials in the first chamber to the second mixing device. The second mixing device includes a second chamber, a second feeding mechanism, and a second mixing mechanism. The second chamber is located directly below the second mixing chamber and is connected to it through the second feeding mechanism. The second mixing mechanism is used to mix the fiber waste and raw materials. The second chamber has a discharge port. The feeding device is used to transfer the mixed fiber raw materials to the discharge port of the second chamber, and the feeding device is used to transfer the mixed fiber waste to the discharge port. By adopting the above technical solution, both the first and second mixing chambers are equipped with blowing mechanisms, which can blow the fibers in the chambers, making the fibers in the chambers more dispersed, which helps the fibers to be more fully mixed in subsequent mixing processes. The first mixing chamber is equipped with a raw material feeding mechanism for feeding fiber raw materials, while the second mixing chamber is equipped with a waste material feeding mechanism for adding fiber scraps. A raw material distribution mechanism then diverts the raw materials from the first mixing chamber to the second mixing chamber, allowing for initial mixing of the fiber raw materials and fiber scraps. Subsequently, the first stirring mechanism in the first stirring device stirs the fiber raw materials entering the first chamber from the first mixing chamber via the first feeding mechanism, further refining and homogenizing the fiber raw materials. A feeding device then conveys the stirred fiber raw materials to the second stirring device, where they are mixed again with the fiber scrap and raw material mixture entering the second chamber via the second feeding mechanism. This two-stage mixing process significantly improves the uniformity of fiber mixing, meeting the high mixing uniformity requirements of high-quality leather fiber fabric production, thus resulting in high-quality leather fiber fabric. Simultaneously, the rational utilization of fiber scraps reduces fiber production costs, avoids resource waste, and promotes the development of the leather fiber industry towards a more environmentally friendly and efficient direction. Preferably, both the first and second blower mechanisms include a blower head and a drive component for driving the blower head.By adopting the above technical solution, the first and second air blowing mechanisms include air blowers and driving components that drive the air blowers. The driving components can drive the air blowers to work, thereby generating airflow. This airflow can blow the fiber raw materials or waste materials in the first and second mixing chambers, putting them in a dynamic dispersed state. This effectively avoids the problem of fibers being difficult to mix due to mutual entanglement or accumulation, thereby greatly improving the mixing uniformity of fibers in their respective mixing chambers, which helps to obtain high-quality leather fiber fabrics in the future, and makes reasonable use of fiber scraps and waste materials, reducing fiber production costs. Preferably, the first and second mixing chambers are respectively provided with two first air blowing mechanisms and two second air blowing mechanisms, and the two air blowers are arranged opposite each other. By adopting the above technical solution, two air blowing mechanisms are provided in both the first and second mixing chambers, and the two air blowers are arranged opposite each other. The oppositely arranged air blowers will form relative airflow. This makes the fibers subject to wind force from different directions in the mixing chamber, preventing the fibers from accumulating together. The fibers will be dispersed under the impact of the relative airflow, increasing the chance of collision and contact between the fibers. This allows for more thorough mixing of fibers, improving the uniformity of fiber mixing within the mixing chamber and contributing to the production of high-quality leather fiber fabrics. It also makes efficient use of fiber scraps and reduces fiber production costs. Preferably, the raw material distribution mechanism includes a distribution pipe and a suction pump. The two ends of the distribution pipe are connected to the first mixing chamber and the second mixing chamber, respectively. The suction pump is installed on the distribution pipe to draw raw materials from the first mixing chamber to the second mixing chamber. By adopting the above technical solution, the raw material distribution mechanism consists of a distribution pipe and a suction pump. The two ends of the distribution pipe are connected to the first and second mixing chambers, respectively, and the suction pump is installed on the distribution pipe. Because the suction pump has a suction effect, it can generate a pressure difference, thereby drawing raw materials from the first mixing chamber to the second mixing chamber through the distribution pipe. This arrangement allows raw materials originally in the first mixing chamber to be smoothly transported to the second mixing chamber, achieving a reasonable distribution of raw materials between the two mixing chambers and helping to improve the efficiency of fiber mixing. Meanwhile, compared to the traditional method of mixing in only one mixing chamber, diverting raw materials from the first mixing chamber to the second mixing chamber increases the mixing path and space, allowing fiber raw materials and waste materials to mix over a larger area, greatly improving the uniformity of fiber mixing. Furthermore, it allows for the effective utilization of fiber scraps, avoiding resource waste and reducing fiber production costs, thus contributing to the production of high-quality leather fiber fabrics. Preferably, both the first and second feeding mechanisms include a first movable plate and a second movable plate, which are installed opposite each other for opening and closing, and both can be flipped downwards. When a certain amount of fiber falls onto the first and second movable plates, both plates flip downwards to allow the fiber to fall off.By adopting the above technical solution, the first and second feeding mechanisms are structured with opposing, downward-flipping movable plates. When fibers fall onto the first and second movable plates, a certain amount of gravity is generated as the fiber quantity gradually increases. When a certain amount is reached, this gravity is sufficient to overcome the original supporting force of the movable plates, causing both the first and second movable plates to flip downwards. This design has several advantages. Firstly, it enables quantitative feeding, ensuring a relatively stable amount of fiber entering the first and second chambers each time, which is beneficial to the uniformity of the subsequent mixing process and avoids affecting the mixing effect due to excessive or insufficient feeding at one time. Secondly, this automatic flipping feeding method improves feeding efficiency and saves labor costs compared to manual feeding. It also reduces errors that may be caused by manual operation, further improving the accuracy and stability of fiber mixing, thereby contributing to improving the overall working performance and product quality of the high-efficiency cotton blending bin used for fiber blending. Preferably, the feeding device includes a first motor, a belt, a drive roller, and multiple driven rollers. The drive roller is rotatably mounted on the first housing, and the multiple driven rollers are rotatably mounted on the second housing. The belt is wound around the drive roller and the multiple driven rollers. The first motor is fixed to one of the housings, and the output shaft of the first motor is fixedly connected to the end of the drive roller. A first guide hole for the belt to pass through is opened on one side of the first housing, and a second guide hole for the belt to pass through is opened on the side wall of the second housing. The belt passes through the first guide hole and the second guide hole in sequence. By adopting the above technical solution, the first motor drives the drive roller to rotate. Since the belt is wound around the drive roller and the multiple driven rollers, the rotation of the drive roller drives the belt to circulate around the drive roller and the driven rollers. The first housing and the second housing respectively have a first guide hole and a second guide hole for the belt to pass through, so that the belt can pass through the two housings in sequence, thereby realizing the material transfer between the first housing and the second housing. In this way, the feeding device can efficiently transfer the mixed fiber raw materials in the first box to the second mixing device, and can also transfer the mixed fiber waste to the discharge port, ensuring smooth transportation of fiber raw materials and fiber waste at different processing stages, avoiding material accumulation and blockage, and improving the continuity and stability of fiber mixing processing. At the same time, this belt-driven feeding method has a relatively simple structure, is easy to maintain and repair, reduces equipment maintenance costs and downtime, further improves production efficiency, helps reduce fiber production costs, and brings better economic benefits to enterprises. Preferably, an observation port for observing the belt is opened on one side of the first box, and the height of the observation port is the same as the height of the belt. By adopting the above technical solution, with an observation port of the same height as the belt on one side of the first box, the operator can directly observe the operation of the belt through the observation port.Since the belt plays a crucial role in conveying the mixed fiber raw materials in the feeding device, its proper operation affects the efficiency and stability of the entire high-efficiency cotton blending bin used for fiber-plastic blending. When the belt experiences problems such as misalignment, breakage, or wear, without an observation port, these issues may go undetected, leading to obstructed fiber transmission and even damage to other components. The observation port allows for timely detection of belt abnormalities, enabling operators to quickly take appropriate measures for adjustment or repair, thus ensuring the stable operation of the feeding device. This ensures the continuous and smooth transmission of fiber raw materials from the first bin to the second mixing device, guaranteeing the high efficiency of the entire fiber mixing and feeding process and improving production efficiency and product quality. Preferably, a sealing block for blocking the observation port is rotatably installed on the first bin. By adopting the above technical solution, the observation port on the first bin allows operators to directly observe the belt's operating status and promptly detect problems such as belt misalignment and wear. A sealing block is rotatably mounted on the first housing to block the observation port. When observation is not required, the sealing block can be rotated to close the observation port, preventing external dust and debris from entering the first housing and contaminating the fiber raw materials or affecting the normal operation of the equipment. This reduces the adverse effects of impurities on the mixing quality, helps maintain the stable operation of the high-efficiency cotton blending silo used for leather and fiber blending, ensures the uniformity of fiber mixing and product quality, and thus facilitates the production of high-quality leather and fiber fabrics. Preferably, the first housing is equipped with a locking device, which includes a mounting block, a cylinder, and a locking block. The locking block is fixed to the first housing, the cylinder is fixed to the locking block, and the piston rod of the cylinder is fixedly connected to the locking block. The cylinder is used to drive the locking block to move towards or away from the sealing block. A limit groove is formed on the side wall of the locking block near the first housing. When the locking block moves to its lowest point, the sealing block is located within the limit groove. By adopting the above technical solution, a locking device is installed on the first housing, which includes a mounting block, a cylinder, and a locking block. Since the locking block is fixed to the first housing, and the cylinder is fixed to the locking block with its piston rod connected to it, the cylinder can drive the locking block to move closer to or further away from the sealing block. A limiting groove is provided on the side wall of the locking block near the first housing; when the cylinder drives the locking block to its lowest point, the sealing block will be positioned within the limiting groove. This design effectively seals the observation port, preventing external dust and debris from entering the first housing and interfering with the mixing process, ensuring a clean mixing environment for the fiber raw materials, and thus helping to improve the mixing effect and make subsequent fiber mixing more uniform. Simultaneously, effective sealing also reduces heat loss (if the mixing process requires a suitable temperature), saves energy consumption, and reduces production costs.Moreover, this flexible locking method allows operators to easily open or close the observation port at any time according to actual conditions, facilitating the inspection of belt operation, timely detection and resolution of potential problems, improving equipment stability and reliability, and extending equipment lifespan. Preferably, the mounting block has an adjustment groove extending vertically; a bolt passes through the adjustment groove and engages with the threaded connection of the first housing. By adopting the above technical solution, by creating an adjustment groove extending vertically on the mounting block and having the bolt pass through the adjustment groove and engage with the threaded connection of the first housing, the position of the mounting block relative to the first housing can be adjusted. When fine-tuning of components such as the locking device is required to adapt to different working conditions or installation needs, simply loosen the bolt, move the mounting block up and down within the vertical range defined by the adjustment groove to the appropriate position, and then tighten the bolt to complete the position adjustment. This adjustable structural design greatly improves the flexibility of device installation and use, avoiding installation difficulties or functional limitations caused by manufacturing errors or changes in component positions during later use, enhancing the stability and adaptability of the entire high-efficiency cotton blending bin for fiber blending processing, and reducing equipment debugging and maintenance time and costs.

[0006] In summary, this application includes at least one of the following beneficial technical effects:

[0007] 1. By setting up a first mixing chamber and a second mixing chamber, the raw materials in the first mixing chamber are diverted to the second mixing chamber by the raw material distribution mechanism, so that the raw materials are more widely distributed. Then, the fiber raw materials are stirred by the first stirring device, and then the mixture of fiber waste and raw materials is further stirred by the second stirring device. After two stirring treatments, the mixing uniformity of the cotton mixing chamber is improved, and high-quality leather fiber fabric can be obtained.

[0008] 2. The second mixing chamber is equipped with a waste feeding mechanism, which allows fiber scraps to enter the second mixing chamber. The second stirring device can stir the mixture of fiber scraps and raw materials, effectively utilizing the fiber scraps that might otherwise be discarded, making reasonable use of fiber scraps and avoiding resource waste.

[0015] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0016] This application discloses a high-efficiency cotton blending bin for processing leather and fiber blends. (Refer to...) Figure 1 and Figure 2 It includes a first mixing device, a second mixing device, a feeding device, a first mixing chamber 4 and a second mixing chamber 5. The first mixing chamber 4 is located directly above the first mixing device, the second mixing chamber 5 is located directly above the second mixing device, and the feeding device is located below the first mixing device and the second mixing device. The feeding device is used to send the material mixed by the first mixing device to the second mixing device. The first mixing chamber 4 is used for mixing raw materials, and the second mixing chamber 5 is used for mixing raw materials and fiber scraps.

[0017] Specifically, in this embodiment, the first mixing chamber 4 is equipped with a first blowing mechanism 41 and a raw material feeding mechanism 42. The first blowing mechanism 41 includes a blower head and a driving component for driving the blower head. The blower head can be a duckbill-shaped or round air outlet component, made of aluminum alloy, which is lightweight and corrosion-resistant. The driving component is a motor, which provides stable drive. The driving component is connected to the blower head through a suitable coupling to ensure stable operation of the blower head. The raw material feeding mechanism 42 is a raw material feeding pipe equipped with a suction device to deliver fiber raw materials to the first mixing chamber 4. The raw material feeding pipe is fixed to the top opening of the first mixing chamber 4 by welding or bolting, facilitating the entry of fiber raw materials into the first mixing chamber 4. The first mixing chamber 4 has two opposing blowers installed on opposite side walls inside the first mixing chamber 4, with opposing airflow directions, which can create convection, allowing the fiber raw materials in the first mixing chamber 4 to tumble fully under the action of the blowing, increasing the contact and mixing opportunities between fibers, thereby improving the initial mixing effect.

[0018] Specifically, in this embodiment, the second mixing chamber 5 is also equipped with a second blowing mechanism 51 and a waste feeding mechanism 52. The structure of the second blowing mechanism 51 is the same as that in the first mixing chamber 4, and its installation method and connection relationship are also the same. The waste feeding mechanism 52 is a waste feeding pipe connected to the fiber edge waste collection equipment. The pipe is connected to the top opening of the second mixing chamber 5 by welding or bolts, which facilitates the feeding of waste into the second mixing chamber 5.

[0019] Specifically, in this embodiment, the first mixing chamber 4 and the second mixing chamber 5 are connected by a raw material distribution mechanism 43. Specifically, the two ends of the distribution pipe 431 of the raw material distribution mechanism 43 are tightly connected to specific interfaces of the first mixing chamber 4 and the second mixing chamber 5, respectively, ensuring a tight seal and preventing fiber leakage. Specifically, the raw material distribution mechanism 43 of this embodiment includes a distribution pipe 431 and a suction pump 432. The two ends of the distribution pipe 431 are connected to the first mixing chamber 4 and the second mixing chamber 5, respectively, and the suction pump 432 is installed on the distribution pipe 431. The distribution pipe 431 is generally made of PVC pipe, with a smooth inner wall, which reduces fiber adhesion during transport. The suction pump 432 is a centrifugal pump suitable for high-flow-rate fiber transport. The suction pump 432 is tightly connected to the distribution pipe 431 via a flange, ensuring no leakage occurs during operation. Through the action of the suction pump 432, the pre-mixed raw material in the first mixing chamber 4 can be smoothly drawn into the second mixing chamber 5, realizing the diversion of raw material between the two mixing chambers.

[0020] Specifically, the first stirring device 1 in this embodiment includes a first housing 11, a first feeding mechanism 12, and a first stirring mechanism 13. The first feeding mechanism 12 includes a first movable plate 121 and a second movable plate 122. The first movable plate 121 and the second movable plate 122 are installed opposite each other to open and close to selectively block the communication between the first housing and the first mixing chamber 4, and both can be flipped downwards. These two movable plates are rotatably installed at the communication opening between the first housing and the first mixing chamber 4 through connecting components such as torsion springs. They can be made of steel plates with smooth surfaces to reduce fiber residue. When the amount of fiber falling on the first movable plate 121 and the second movable plate 122 reaches a certain amount, due to gravity, both the first movable plate 121 and the second movable plate 122 flip downwards, causing the fiber to fall into the first housing. The first stirring mechanism 13 is disposed inside the first housing 11 and is used to stir the fiber raw materials.

[0021] Continue to refer to Figure 2 Specifically, the first stirring mechanism 13 includes a support rod 131, a stirring element 132, and a second motor 133. The support rod 131 is located inside the first housing, and both ends of the support rod 131 are fixedly connected to the first housing. The bottom end of the stirring element 132 is rotatably connected to the support rod 131. The second motor 133 is fixed to the lower surface of the support rod 131, and the output shaft of the second motor 133 is fixedly connected to the bottom end of the stirring element 132. The second motor 133 drives the stirring element 132 to rotate, which facilitates the stirring of the fiber raw materials during rotation. In this process, the support rod 131 not only supports the stirring element 132 and the second motor 133, but also does not obstruct the fiber raw materials from falling to the feeding device 3.

[0022] Reference Figure 2 The second mixing device 2 includes a second housing 21, a second feeding mechanism 22, and a second mixing mechanism 23. The second feeding mechanism 22 includes a first movable plate 121 and a second movable plate 122. The first movable plate 121 and the second movable plate 122 are installed opposite each other for opening and closing to selectively block the communication between the first housing and the first mixing chamber 4, and both can be flipped downwards. These two movable plates are rotatably installed at the communication opening between the first housing and the first mixing chamber 4 through connecting components such as torsion springs. The structure and installation method are the same as those of the first feeding mechanism 12. The second mixing mechanism 23 is located inside the second housing 21 and is used to mix the fiber raw materials. The structure and working principle of the second mixing mechanism 23 are exactly the same as those of the first mixing mechanism 13, and will not be described in detail here.

[0023] Reference Figure 2 and Figure 3The feeding device 3 includes a first motor 31, a belt 32, a drive roller 33, and multiple driven rollers 34. The drive roller 33 is rotatably mounted on the first housing 11, and the multiple driven rollers 34 are rotatably mounted on the second housing 21. The belt 32 is arranged around the drive roller 33 and the multiple driven rollers 34. The first motor 31 is fixed to one of the housings, and the output shaft of the first motor 31 is fixedly connected to the end of the drive roller 33. The first motor 31 is used to drive the drive roller 33 to rotate.

[0024] Reference Figure 4 The first housing 11 has a first through hole 111 on one side for the belt 32 to pass through, and the second housing 21 has a second through hole 212 on its side wall for the belt 32 to pass through. Both the first through hole 111 and the second through hole 212 extend along a second direction. The belt 32 passes through the first through hole 111 and the second through hole 212 in sequence. The second housing has a discharge port 211 on its side wall opposite to the first housing, which extends along the second direction and is closed at both ends. The first motor 31 drives the active roller 33 to rotate. During the rotation of the active roller 33, the belt 32 rotates. The belt 32 not only facilitates the transfer of the stirred fibers in the first box 11 to the discharge port 211, but also facilitates the transfer of the stirred fibers in the second box 21 to the discharge port 211.

[0025] In this embodiment, the first housing 11 has an observation port on one side for observing the belt 32. The length of the observation port extends along the first direction, and both ends of the observation port are closed. The height of the observation port is the same as the height of the belt 32. Therefore, the staff can observe whether the belt 32 is moving through the observation port.

[0026] A sealing block for sealing the observation port is rotatably mounted on the first housing 11. Specifically, the bottom of the sealing block is rotatably connected to the first housing 11 via two or more hinges. The sealing block seals the observation port, preventing cotton inside the first housing 11 from leaking out. Simultaneously, because the bottom of the sealing block is rotatably connected to the first housing 11, when the operator opens the sealing block, it flips downwards under its own weight, eliminating the need for manual flipping and saving effort. The sealing block is made of a transparent material, allowing the operator to easily observe whether the belt 32 is moving.

[0027] A handle is fixedly installed on the sealing block. Workers can rotate the sealing block by turning the handle, which not only saves effort but also protects the worker's hands and increases the convenience of turning the sealing block over. The sealing block is locked in place by a locking device.

[0028] The implementation principle of the above embodiment is as follows: During the production process, fiber raw materials are added to the first box 11 by the first feeding mechanism 12, and the fiber raw materials are stirred by the first stirring mechanism 13. The stirred fiber raw materials fall to the feeding device 3 under their own gravity. The feeding device 3 conveys the stirred fiber raw materials from the first box 11 to the second box 21, and then conveys them to the next process through the discharge port 211 of the second box 21. At the same time, fiber waste is added to the second box 21 by the second feeding mechanism 22, and the fiber waste is stirred by the second stirring mechanism 23. The stirred fiber waste falls to the conveying device under its own gravity, and the conveying device conveys the stirred fiber waste to the next process.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
