Description
Technical Field
[0001] This utility model relates to the field of fabric production technology, and in particular to an energy-saving and environmentally friendly recycled denim fabric production equipment. Background Technology
[0002] Denim is a strong, dense, and complex textile, typically made of cotton yarn, sometimes blended with polyester, spandex, etc., woven together through warp and weft yarns and then dyed and finished. It cannot be directly melted and granulated like plastic bottles. The core goal of recycled fibers is to transform waste textiles back into fiber raw materials that can be used for spinning. Therefore, the fabric's structure must be broken down, restoring it to a loose fibrous state.
[0003] In the reprocessing of recycled denim fabric, machines use high-speed rotating toothed rollers, rivets, or blades to forcefully tear, cut, and pull denim fragments, breaking down the hard fabric into increasingly smaller fiber bundles and individual fibers.
[0004] In the aforementioned process, the opened fibers need to undergo multiple cleaning processes to separate lightweight dust or short fibers. This step is crucial for improving fiber quality and protecting subsequent equipment. Currently, commonly used equipment uses airflow to separate most of the lightweight dust and short fibers. This process requires a filter to block the normal fibers. The fibers, under the influence of airflow, adhere to the filter, affecting the filtration of lightweight dust and short fibers to some extent. While agitating the fibers can separate them from the filter to some extent, normal fibers will also be filtered out during the agitation. Therefore, an improvement is proposed. Utility Model Content
[0005] In view of the above-mentioned problems, the technical problem to be solved by this utility model is to provide an energy-saving and environmentally friendly recycled denim fabric production equipment.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an energy-saving and environmentally friendly recycled denim fabric production equipment, including a frame, a driver on the frame and a separation frame at the outer end of the driver. The separation frame has an air outlet for airflow movement, a limit ring is installed on the inner wall, and an installation port communicating with the interior is opened on the outer side. The separation frame has a filter part that is locked inward from the installation port into the limit ring. The driver is used to drive the filter part to rotate.
[0007] The filter section includes fixed ends located at both ends, and between the two fixed ends there are several sets of support shafts circumferentially distributed along the axis of the fixed ends. The several sets of support shafts can be slidably arranged inward and outward. There is an elastic filter screen between each support shaft and the adjacent support shaft. The filter screen has an opening controlled by a zipper.
[0008] The separator is equipped with several sets of circumferentially distributed auxiliary parts, which are used to squeeze the support shaft and make the support shaft move toward the axis of the fixed end.
[0009] A further preferred embodiment of this utility model is as follows: both fixed ends include connecting ends, and several sets of circumferentially distributed sliding grooves are provided on the side of the two sets of connecting ends that are close to each other. The inner end of the sliding groove points to the axis of the connecting end, and an inner shaft slides in the sliding groove. A support shaft is fixed between the inner shafts of the two sets of connecting ends that are opposite to each other. An elastic element is fixed at the inner end of the sliding groove for supporting the inner shaft from the inside out.
[0010] A further preferred embodiment of this utility model is as follows: two cover rings are fixed on the side of the two sets of connecting ends that are close to each other. The two cover rings are of different sizes and are nested together. The two cover rings are used to close the inner and outer sections of the slide groove. When the inner shaft slides along the slide groove, both ends of the inner shaft are covered by the two cover rings respectively.
[0011] A further preferred embodiment of this utility model is: an inner tube that coincides with the axis of the two sets of connecting ends is fixed between them, one end of the inner tube passes through the outer connecting end to form a vent, and the other end passes through the inner connecting end to form a mating port. The vent is used to input external gas.
[0012] The driver output has an output shaft, and the end of the output shaft has a mating groove. The output shaft is engaged with the mating port through the mating groove.
[0013] A further preferred embodiment of this utility model is: the outer wall of the inner tube has multiple long grooves that communicate with its interior.
[0014] A further preferred embodiment of this utility model is: the diameters of the inner and outer sets of connecting ends are arranged in a small and a large manner, with the smaller set of connecting ends being locked inside the limiting ring and the larger set of connecting ends being locked outside the mounting opening.
[0015] A further preferred embodiment of this utility model is: a locking block is fixed on the outside of the separating frame, and a separable baffle is locked inside the locking block. The inner side of the baffle is in contact with the outer side of a large set of connecting ends, and the outer side of the baffle has a connecting hole for connecting with an air source, and the connecting hole communicates with the air hole.
[0016] A further preferred embodiment of this utility model is: two layers of elastic ropes are fixed between two adjacent sets of support shafts, with the inner side of each layer of elastic ropes connected to the filter screen and the outer side in contact with the connecting end.
[0017] A further preferred embodiment of this utility model is: the support shaft is a shaft with a circular cross-section;
[0018] The auxiliary part includes a circular component fixed inside the separator. The circular component is located on the path of the circular motion of the support shaft, and the circular component is pressed against the arc surface of the circular component when the support shaft moves in a circular motion.
[0019] A further preferred embodiment of this utility model is: the circular part is made of hollow metal with a smooth outer wall, and the support shaft is also made of metal with a smooth outer wall.
[0020] Compared with the prior art, the advantages of this utility model are:
[0021] 1. When the support shaft rotates, it periodically collides with the circular part of the auxiliary part, forcing the support shaft to slide inward and compress the elastic part. This reciprocating motion drives the elastic filter to vibrate at high frequency and deform periodically, effectively shaking off the dust or short fibers embedded in the filter holes, greatly relieving clogging. At the same time, the high-frequency vibration also cleans the dust or short fibers in the fibers, maintaining the fiber shape as much as possible and preventing the fibers from escaping outward with the dust.
[0022] 2. When the support shaft moves inward, the elastic filter screen is stretched, and the mesh expands and deforms instantly. When it is reset, the mesh returns to its original state, and physical cleaning of the mesh is performed.
[0023] 3. The fibers are mainly subjected to uniform airflow, avoiding strong mechanical compression that would cause dust to become trapped inside the fibers, and keeping the fibers in a loose state to facilitate the escape of dust. Attached Figure Description

[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0033] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.
[0034] This embodiment mainly describes an energy-saving and environmentally friendly equipment for producing recycled denim fabric. Please refer to [link / reference needed]. Figures 1-6 Specifically, the current commonly used equipment uses airflow to separate most of the lightweight dust and short fibers. This process requires filters to block the normal fibers. However, the fibers adhere to the filters due to the airflow, which more or less affects the filtration of lightweight dust and short fibers. Based on this, an improvement is proposed: an energy-saving and environmentally friendly recycled denim fabric production equipment, such as... Figures 1-3 As shown, the device includes a frame 1, a driver 2 on the frame 1, and a separation frame 3 at the outer end of the driver 2. The separation frame 3 has an air outlet 31 for airflow movement. The separation frame 3 is turbine-shaped and has an air outlet 31. Light dust and short fibers moving outward from the air outlet 31 need further treatment to avoid direct discharge. A limit ring 32 is installed on the inner wall, and an installation port 33 communicating with the inner wall is opened on the outer side. The limit ring 32 and the installation port 33 are used to limit the filter part 4 so that it can rotate while maintaining stability. The separation frame 3 has a filter part 4 that is locked inward from the installation port 33 into the limit ring 32. The driver 2 is used to drive the filter part 4 to rotate. It should be noted that the driver 2 is a servo motor, which drives the filter part 4 to rotate under the action of the servo motor.
[0035] The filter section 4 includes fixed ends 41 located at both ends. Between the two fixed ends 41, there are several sets of support shafts 42 circumferentially distributed along the axis of the fixed ends 41. These support shafts 42 are slidably arranged inwards and outwards. Each support shaft 42 has an elastic filter screen between it and its adjacent support shaft 42. The filter screen has an opening controlled by a zipper. Figure 2For a state with a filter, such as Figure 3 As shown, the filter screen is hidden in order to observe the structure more clearly. When several sets of support shafts 42 slide in the inward and outward directions under the action of the auxiliary part 5, the filter screen will vibrate, causing the internal fibers to vibrate and cleaning the holes of the filter screen at the same time.
[0036] The separator 3 is equipped with several sets of circumferentially distributed auxiliary parts 5, which are used to squeeze the support shaft 42 and make the support shaft 42 move toward the axis of the fixed end 41.
[0037] Specifically, the filter screen has a zipper-controlled opening for easy loading and unloading of fibers. At the same time, the filter screen is elastic. When the support shaft 42 moves inward, it will pull on the filter screen, causing the mesh of the filter screen to deform. Light dust and short fibers located in the mesh will be squeezed out, and then the mesh will recover, which helps to discharge the objects stuck in the mesh.
[0038] like Figure 3 and Figure 5 As shown, both fixed ends 41 include connecting ends 411. Several sets of circumferentially distributed sliding grooves 412 are provided on the side of the two sets of connecting ends 411 that are close to each other. The inner end of the sliding groove 412 points to the axis of the connecting end 411. An inner shaft 413 slides in the sliding groove 412. The support shaft 42 is fixed between the inner shafts 413 of the two sets of connecting ends 411. An elastic element 414 is fixed at the inner end of the sliding groove 412 for supporting the inner shaft 413 from the inside out.
[0039] Specifically, the two sets of connecting ends 411 are used to support the support shaft 42 and also allow it to slide in the inward and outward directions. It should be noted that the elastic element 414 is a spring, used to support the inner shaft 413.
[0040] like Figure 5 As shown, two rings of cover 415 are fixed on the side of the two sets of connecting ends 411 that are close to each other. The two rings of cover 415 are of different sizes and are nested together. The two rings of cover 415 are used to close the inner and outer sections of the slide groove 412. When the inner shaft 413 slides along the slide groove 412, both ends of the inner shaft 413 are covered by the two rings of cover 415 respectively.
[0041] Specifically, the main function of the two cover rings 415 is to cover the gaps in the slide groove 412 to prevent fibers from getting stuck inside. When the inner shaft 413 slides to the two ends, the two cover rings 415 keep covering the two ends of the inner shaft 413. When the inner shaft 413 slides, the slide groove 412 is kept clean to avoid affecting the movement of the inner shaft 413.
[0042] like Figures 3-5As shown, an inner tube 43 is fixed between the two sets of connecting ends 411 and coincides with its axis. One end of the inner tube 43 passes through the outer connecting end 411 to form an air hole 431, and the other end passes through the inner connecting end 411 to form a mating port 432. The air hole 431 is used to input external gas.
[0043] The output end of the driver 2 has an output shaft 21, and the end of the output shaft 21 has a mating groove 22. The output shaft 21 is engaged with the mating port 432 through the mating groove 22.
[0044] Specifically, the inner tube 43 is mainly used for gas transportation. The air hole 431 formed at one end of the inner tube 43 allows the airflow to move inward, and the mating groove 22 at the other end mates with the output shaft 21 and is in a closed state. During the airflow movement, it moves outward from the outer wall of the inner tube 43. The output shaft 21 is engaged with the mating port 432 through the mating groove 22, allowing the filter section 4 to be directly removed outward, which is convenient for installation and disassembly.
[0045] The outer wall of the inner tube 43 has multiple long grooves that communicate with its interior. Specifically, the airflow moves outward from the outer wall of the inner tube 43, moving outward as evenly as possible, along the circumference of the inner tube 43, and uniformly generating airflow for the fibers located in the filter section 4.
[0046] like Figure 3 As shown, the inner and outer sets of connecting ends 411 have different diameters, one set being smaller and the other larger. The smaller set of connecting ends 411 is engaged within the limiting ring 32, while the larger set of connecting ends 411 is engaged outside the mounting opening 33. Specifically, the smaller set of connecting ends 411 of the filter section 4 is engaged within the limiting ring 32, while the larger set of connecting ends 411 is engaged outside the mounting opening 33. Both ends of the filter section 4 are limited to maintain a stable state when it rotates.
[0047] like Figure 3 As shown, a locking block 62 is also fixed on the outside of the separating frame 3. A separable baffle 6 is locked inside the locking block 62. The inner side of the baffle 6 is in contact with the outer side of a large set of connecting ends 411. The outer side of the baffle 6 has a connecting hole 61 for connecting with the air source. The connecting hole 61 is connected to the air hole 431.
[0048] Specifically, the baffle 6 can be separated from the locking block 62 upwards and can be locked together with the locking block 62 downwards. After installation, the baffle 6 fits against the outer side of the large set of connecting ends 411, so that the baffle 6 supports the filter part 4, which facilitates the removal and disassembly of the filter part 4. It should be noted that the connecting hole 61 on the outer side of the baffle 6 is used to connect to the air pump, so that the airflow moves inward from the connecting hole 61. The installation and disassembly of the baffle 6 can separate and engage the airflow with the filter part 4, which is convenient for operation.
[0049] like Figure 5As shown, two layers of elastic ropes 421 are fixed between two adjacent sets of support shafts 42. The inward side of both layers of elastic ropes 421 is connected to the filter screen, and the outward side is in contact with the connecting end 411. Specifically, the two layers of elastic ropes 421 are used to connect the sides of the filter screen, ensuring that the filter screen is in contact with the connecting end 411 as much as possible, and preventing the fibers from moving outward from the gaps under the action of airflow. It should be noted that the elastic ropes 421 do not affect the movement of the support shafts 42.
[0050] like Figure 6 As shown, the support shaft 42 is a shaft with a circular cross-section;
[0051] The auxiliary part 5 includes a circular part 51 fixed inside the separator 3. The circular part 51 is located on the path of the circular movement of the support shaft 42. When the support shaft 42 moves in a circular motion, it is pressed against the arc surface of the circular part 51.
[0052] Specifically, when the filter section 4 rotates, the support shaft 42 performs a circular motion and is pressed against the outer arc surface of the circular part 51, causing the support shaft 42 to move along the arc surface of the circular part 51 to achieve inward movement. After passing through the circular part 51, it will return to its original position, generating vibration during this process.
[0053] The circular component 51 is made of hollow metal with a smooth outer wall, and the support shaft 42 is also made of metal with a smooth outer wall, in order to minimize the friction between the two and make the operation smoother.
[0054] Working principle: The driver 2 is a servo motor. Its output shaft 21 is engaged with the inner connection end 411 to drive the filter part 4 to rotate. During the rotation, airflow is delivered inward from the connection hole 61 of the baffle 6. The airflow moves to the interior of the filter part 4 and the fiber structure through the air hole 431. Under the action of the airflow, the light dust and short fibers inside the fiber are driven to move outward and outward from the filter screen and outward from the air outlet 31.
[0055] During the above process, the support shaft 42 is squeezed against the circular part 51 during its circumferential motion, causing the support shaft 42 to move towards the inner tube 43. While the inner shaft 413 slides, the elastic part 414 is compressed, causing the filter screen to deform. After passing the circular part 51, the squeezed support shaft 42 will return to its original position under the action of elasticity. During this process, the filter screen deforms, which better maintains the permeability of the filter screen. Secondly, a certain degree of vibration is also generated. While the light dust and short fibers on the filter screen are easy to fall off, the internal fibers generate a certain degree of vibration, which makes it easy for the light dust and short fibers to separate from the fibers. At the same time, the shape of the fibers is maintained as much as possible to prevent them from being scattered and easily moving out of the filter screen.
[0056] Secondly, gas is generated outward from the inner tube 43. The combined effect of the gas and the centrifugal force from the circular motion causes the fibers to adhere to the filter screen. Therefore, as the filter screen vibrates, the fibers are subjected to the same force, which separates the light dust and short fibers. It should be noted that the fibers are only subjected to the gas and the centrifugal force from the circular motion, preventing excessive compression that would trap the light dust and short fibers within the fibers, thus maintaining the fibers in a loose state.
