Description

Technical Field

[0001] This invention belongs to the field of coated fabric waste recycling technology, specifically a waste recycling device and recycling method for coated fabric. Background Technology

[0002] Currently, some fields require nonwoven fabrics to have high wear resistance. Existing technologies usually solve these problems by using nonwoven fabric as a base layer and coating it with a coating to make coated fabric. However, during the processing of coated fabric, excess scraps or waste are usually generated. In order to avoid waste, they are usually collected and crushed for further processing.

[0003] However, in actual work, the messy scraps of non-woven fabric contain long strips of waste that can easily entangle the crushing parts, affecting the crushing effect and even completely jamming the rotating parts of the crushing equipment, causing damage to the equipment. Moreover, in actual use, the scraps or waste collected by workers from various processes often have various impurities attached to them. If they are crushed directly and then used, it can easily affect the quality of the final product.

[0004] Chinese Patent CN113042171B discloses a waste recycling device and method for coated fabric, including a housing with a feed hopper and a discharge port. The housing contains a cleaning component and a shredding component. The shredding component includes two parallel crushing rollers with crushing blades mounted rotatably in the lower part of the housing cavity. A drive component is located outside the housing to drive the two crushing rollers to rotate synchronously. In daily use, after the coated fabric enters the housing cavity through the feed hopper, the cleaning component cleans the dust and impurities adhering to its surface. Then, the drive component drives the two parallel crushing rollers to rotate, causing the crushing blades on the outer walls of the crushing rollers to shred the coated fabric after cleaning. The cleaned coated fabric is discharged from the housing through the discharge port. The crushing blades, installed on the outer walls of each crushing roller and arranged in an alternating pattern, remove the coated fabric wrapped around the crushing blades on the outer walls of the opposite crushing rollers as the rollers rotate.

[0005] However, the aforementioned patents still have the following drawbacks:

[0006] 1. According to the description of the above patent, the above patent uses crushing blades that are installed on the outer wall of each crushing roller and are arranged in an alternating manner to remove the coating cloth wrapped around the outer wall of the crushing roller when the crushing roller rotates. However, in actual use, the alternating blades cannot directly contact the crushing roller, making it difficult to effectively remove the long strips of waste wrapped around the outer wall of the crushing roller, which easily affects the crushing and normal rotation of the blades.

[0007] 2. In actual use, the above-mentioned patent requires a gap between the blades to avoid blade breakage and damage. Consequently, the above-mentioned patent is unable to effectively remove the waste material wrapped around the blades, which can lead to obstruction of the blades, affecting the crushing effect, or even causing the blades to bend and deform, thus damaging the equipment.

[0008] 3. The above-mentioned patent cleans the waste materials before crushing them. However, when the waste materials are crushed and torn, they inevitably produce fine fibers. The above-mentioned patent cannot remove these fine fibers, resulting in a low degree of cleanliness in the final product, which affects subsequent recycling. Furthermore, the waste cleaning process of the above-mentioned patent is too short, which cannot fully clean the waste materials and affects the quality of the final product. Summary of the Invention

[0009] To overcome the shortcomings of existing technologies, this invention addresses the technical problem by incorporating a blower hood and a first filter element. This allows for simultaneous air-separation cleaning during the crushing of edge waste, removing dust and fibers generated during fabric tearing. Furthermore, water is sprayed onto the air-separated edge waste for further cleaning, removing oil stains and other contaminants, resulting in more comprehensive cleaning and ensuring high-quality waste recycling. The cleaning step, occurring after the crushing step, effectively avoids the problem of unremoved fibers from fabric tearing. The cylindrical design prevents long strips of edge waste from tangling on the first cutter shaft. The large diameter of the cylinder reduces the probability of waste material entanglement on the cylinder surface. Furthermore, the eccentric arrangement and synchronous rotation of the cylinder and the first cutter shaft allow the blade to continuously extend and slide within the cutter groove during rotation. When the blade retracts, a brush removes the waste material entangled on its surface, ensuring more thorough crushing and preventing blade bending and deformation caused by waste entanglement. The tapered ends at both ends of the cylinder prevent entanglement at the rotating connection between the cylinder and the side plates. If long strips of waste material do become entangled on the outside of the cylinder, a cutter and a cutting groove are incorporated, causing the cutter, which meshes with the groove, to rotate synchronously with the cylinder during rotation, cutting off the entangled waste material and effectively resolving the entanglement problem.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a waste recycling device for coated fabrics, comprising:

[0011] The housing has two side plates fixedly connected to both ends, and two first cutter shafts are rotatably connected between the two side plates. Each first cutter shaft has a set of cutter holders fixedly connected to it, and two sets of mutually symmetrical blades are fixedly connected to the two sets of cutter holders respectively.

[0012] The cylinder has two cylinders rotatably connected between the two side plates. Each cylinder surrounds the outside of the first cutter shaft, and each cylinder has a groove on its surface to accommodate the protrusion of the blade.

[0013] Each of the cylinders is eccentrically positioned with respect to the corresponding first cutter shaft. A base plate is fixedly connected to the bottom of the housing between the two cylinders. Multiple perforations are evenly distributed on the base plate. A hopper is fixedly connected to the top of the housing. A cleaning and drying component is provided at the bottom of the housing.

[0014] Each of the blade grooves has a brush fixedly connected to both sides. Each brush can slide in close contact with the corresponding blade. The tip of each blade is trapezoidal, and the cutting edge of each blade is an inward arc.

[0015] Each of the cylinders has tapered ends at both ends, and a synchronous gear ring is fixedly connected to the inner wall of each cylinder. A synchronous gear is fixedly connected to each of the first cutter shafts at the corresponding position of each synchronous gear ring. Each synchronous gear meshes with the corresponding synchronous gear ring for transmission.

[0016] Two second cutter shafts are symmetrically distributed and rotatably connected between the two side plates. Multiple cutters are fixedly connected evenly on the surface of each second cutter shaft. A set of cutting grooves is evenly distributed on the surface of each cylinder. Each cutter can engage with the cutting grooves. A cover for the cutters is fixedly connected to the inner wall of the shell near each set of cutting grooves.

[0017] The bottom of the housing has two sets of ventilation holes on both sides of the base plate. A first filter element shell with uniform holes is fixedly connected to the outside of the housing outside each set of ventilation holes. A first filter element is fixedly connected inside each first filter element shell. Two blower hoods communicating with the inside of the housing are fixedly connected to the top of the housing. The ends of the two blower hoods are fixedly connected to air ducts. A high-pressure blower is fixedly connected to the end of the air duct away from the blower hood.

[0018] Two first cutter shafts are fixedly connected to the ends of the side plates, and the two drive gears are meshed and connected. A gear cover is fixedly connected to the outside of the side plates to cover the drive gears. A second motor is fixedly connected to the outside of the gear cover. The power output end of the second motor passes through the gear cover and is connected to a driven gear. The driven gear is meshed and connected to one drive gear.

[0019] The cleaning and drying component includes a cleaning box, which is fixedly connected to the bottom of the housing. A water spray pipe is fixedly connected between the two side plates below the drain hole. Multiple nozzles are fixedly connected to the bottom of the water spray pipe. Two pulleys are rotatably connected between the two ends of the cleaning box. A metal mesh belt with fine mesh is driven between the two pulleys. The metal mesh belt is inclined. A first motor is fixedly connected to the outside of the cleaning box. The power output end of the first motor is drivenly connected to one of the pulleys.

[0020] The bottom of the cleaning box is fixedly connected to a second filter cartridge shell, a second filter cartridge is installed inside the second filter cartridge shell, a water pump is fixedly connected to one side of the second filter cartridge shell, and a water injection pipe is connected between the water pump and the water spray pipe.

[0021] A drying box is fixedly connected to one side of the cleaning box below the end of the metal mesh belt. A drawer is slidably connected inside the drying box below the metal mesh belt. A metal mesh with fine mesh is fixedly connected to the bottom of the drawer. A heater is fixedly connected to the bottom of the drying box below the drawer.

[0022] A method for recycling waste materials from coated fabrics, the method flow is as follows:

[0023] S1: Crushing step: The scrap materials to be recycled are put into the shell, and the first cutter shaft drives the blades to rotate at high speed to fully crush the scrap materials for subsequent recycling.

[0024] S2: Air separation step. During the process of the blades rotating at high speed to break up the corner waste, the air blown out from the blower hood continuously passes through the first filter element shell to form a high-speed airflow. The dust attached to the corner waste and the fibers generated by the tearing of the cloth will be carried into the first filter element by the high-speed airflow and separated from the broken corner waste.

[0025] S3: Cleaning step. The broken scraps fall onto the surface of the metal mesh belt through the holes. Water is sprayed onto the surface of the metal mesh belt through the nozzle to thoroughly clean the broken scraps.

[0026] S4: Drying step. The cleaned scraps are continuously conveyed into the drying chamber by a metal mesh belt. The cleaned scraps fall onto the surface of the metal mesh and are heated by the heater, gradually drying the scraps for subsequent recycling.

[0027] In summary, compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] (1) By setting up a blower hood and a first filter element, air separation cleaning can be carried out simultaneously during the crushing of corner waste. Dust that falls off the surface of corner waste during the crushing process, as well as fibers generated when the fabric is torn, are directly removed during the crushing process, thereby improving the recycling and cleaning effect of corner waste and improving the recycling quality.

[0029] (2) By setting the nozzle, water can be sprayed onto the corner waste after air separation to further clean the corner waste, remove oil stains and other contaminants in the waste, so that the waste is cleaned more thoroughly, ensuring the quality of waste recycling. Moreover, the cleaning step is after the crushing step, which effectively avoids the problem of fibers that cannot be removed when the cloth is torn during crushing.

[0030] (3) By setting the cylinder, long strips of waste material are prevented from getting tangled on the first cutter shaft. The large diameter of the cylinder reduces the probability of waste material getting tangled on the surface of the cylinder. The eccentric setting of the cylinder and the first cutter shaft and their synchronous rotation allow the blade to continuously slide and extend within the cutter groove during rotation. When the blade retracts, the brush removes the waste material tangled on the surface of the blade, allowing the waste material to be broken up more thoroughly and preventing the blade from bending and deforming due to the waste material getting tangled on the blade.

[0031] (4) The tapered ends at both ends of the cylinder make it less likely for the cylinder to entangle at the rotating connection with the side plate. If some long strips of waste material are entangled on the outside of the cylinder, the cutter and the slot are set so that the cylinder can be driven to rotate synchronously during rotation and the cutter meshing with the slot can be cut off and the waste material entangled on the surface of the cylinder can be effectively solved.

[0042] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] like Figure 1-9 As shown, a waste recycling device and method for coated fabric includes a housing 10. Two side plates 11 are fixedly connected to both ends of the housing 10. A hopper 12 is fixedly connected to the top of the housing 10. A bottom plate 13 is fixedly connected to the bottom of the housing 10. Multiple perforations 14 are evenly distributed on the bottom plate 13. Two sets of ventilation holes 30 are respectively opened on both sides of the bottom of the housing 10 at the bottom of the bottom plate 13. A first filter element shell 28 is fixedly connected to the outside of the housing 10 at the corresponding position of each set of ventilation holes 30. A first filter element 29 is fixedly connected inside the first filter element shell 28. Two blower hoods 41 are symmetrically distributed and fixedly connected to the top of the housing 10 on both sides of the hopper 12. Each blower hood 41 communicates with the inside of the housing 10. Air pipes 42 are fixedly connected to the ends of the two blower hoods 41. A high-pressure blower 43 is fixedly connected to the end of the air pipe 42 away from the blower hood 41.

[0044] By setting up the blower hood 41 and the first filter element 29, air separation cleaning can be carried out simultaneously during the crushing of edge waste. Dust that falls off the surface of edge waste during the crushing process, as well as fibers generated when the fabric is torn, are directly removed during the crushing process, thereby improving the recycling and cleaning effect of edge waste and improving the recycling quality.

[0045] like Figure 1-9As shown, a cleaning box 33 is fixedly connected to the bottom of the housing 10. A water spray pipe 31 is fixedly connected between the two side plates 11 below the leakage hole 14. Multiple nozzles 32 are evenly distributed and fixedly connected to the bottom side of the water spray pipe 31. A second filter cartridge shell 39 is fixedly connected to one side of the bottom of the cleaning box 33. A second filter cartridge 40 is installed inside the second filter cartridge shell 39. A water pump 38 is fixedly connected to one side of the second filter cartridge shell 39. A water injection pipe 37 is connected between the water pump 38 and the water spray pipe 31. A set of pulleys 34 is rotatably connected between the two ends of the cleaning box 33. An inclined metal mesh belt 35 with fine mesh holes is driven between the two pulleys 34. A first motor 36 is fixedly connected to the outside of the cleaning box 33. The power output end of the first motor 36 passes through the cleaning box 33 and is driven by one of the pulleys 34.

[0046] By setting nozzle 32, water can be sprayed onto the corner waste after air separation to further clean the corner waste, remove oil stains and other contaminants in the waste, so that the waste is cleaned more thoroughly, ensuring the quality of waste recycling. Moreover, the cleaning step is after the crushing step, which effectively avoids the problem of fibers that cannot be removed when the cloth is torn during crushing.

[0047] like Figure 1-9 As shown, one end of the metal mesh belt 35 extends upwards into the cleaning box 33. A drying box 44 is fixedly connected to the cleaning box 33 below the end of the metal mesh belt 35. A drawer 45 is slidably connected inside the drying box 44. A metal mesh surface 46 with fine mesh holes is fixedly connected to the bottom of the drawer 45. A heater 47 is fixedly connected to the bottom of the drying box 44 below the drawer 45.

[0048] The metal mesh belt 35 continuously transports the cleaned scraps into the drying chamber 44. By setting up the metal mesh 46 and the heater 47, the cleaned waste can be dried, thus obtaining dried waste fragments in one stop, saving processes and improving recycling efficiency.

[0049] like Figure 1-9As shown, two first cutter shafts 16 are rotatably connected between the two side plates 11. A set of cutter holders 20 is fixedly connected to each first cutter shaft 16. A set of blades 17 evenly distributed in a circumferential direction is fixedly connected to each set of cutter holders 20. Two cylindrical bodies 15 are symmetrically distributed and rotatably connected between the two side plates 11. Each cylindrical body 15 surrounds the outside of the corresponding first cutter shaft 16 and is eccentrically set to the corresponding first cutter shaft 16. A cutter groove 18 is opened on each cylindrical body 15 at the corresponding position of each blade 17 to accommodate the blade 17 extending out. A brush 19 is fixedly connected in each cutter groove 18 and slides relatively close to the corresponding blade 17. A synchronous gear ring 22 is fixedly connected inside the end of each first cutter shaft 16. A synchronous gear 21 is fixedly connected at both ends of each first cutter shaft 16 at the corresponding position of each synchronous gear ring 22. Each synchronous gear 21 meshes with the corresponding synchronous gear ring 22 for transmission.

[0050] By setting the cylinder 15, long strips of scrap material are prevented from getting tangled on the first cutter shaft 16. Furthermore, due to the large diameter of the cylinder 15, the probability of scrap material getting tangled on the surface of the cylinder 15 is reduced. Moreover, by setting the cylinder 15 and the first cutter shaft 16 eccentrically and rotating synchronously, the blade 17 continuously extends and slides within the cutter groove 18 during rotation. Then, when the blade 17 retracts, the brush 19 removes the scrap material tangled on the surface of the blade 17, allowing the scrap material to be broken up more thoroughly and preventing the blade 17 from bending and deforming due to scrap material getting tangled on it.

[0051] like Figure 1-9 As shown, tapered ends 24 are provided at both ends of the cylinder 15. Multiple grooves 23 are evenly distributed on the surface of the cylinder 15 in the circumferential direction. Two second cutter shafts 25 are symmetrically distributed and rotatably connected between the two side plates 11. A set of cutters 26 are evenly distributed and fixedly connected on the surface of each second cutter shaft 25. The cutters 26 can mesh with the corresponding grooves 23. A cover 27 is fixedly connected to the inner wall of the shell 10 at the corresponding position of each set of cutters 26 to cover the cutters 26.

[0052] The tapered ends 24 at both ends of the cylinder 15 prevent entanglement at the rotating connection between the cylinder 15 and the side plate 11. Furthermore, if some long strips of waste material become entangled on the outside of the cylinder 15, the cutter 26 and the cutting groove 23 are provided so that the cutter 26, which meshes with the cutting groove 23, rotates synchronously during the rotation of the cylinder 15, cutting off the waste material entangled on the surface of the cylinder 15, thereby effectively solving the entanglement problem.

[0053] By setting the shield 27, waste material can be prevented from passing through the top of the cutter 26, ensuring that the waste material can stably enter between the two sets of blades 17 for crushing. Furthermore, since the blades 17 are completely retracted into the cylinder 15 near the cutter 26, the cutter 26 will not obstruct the operation of the blades 17.

[0054] like Figure 1-9 As shown, the ends of the two first cutter shafts 16 extending out of the side plate 11 are respectively fixedly connected to the drive gears 50. The two drive gears 50 are meshed and connected in a transmission manner. A gear cover 48 covering the drive gears 50 is fixedly connected to the outside of the side plate 11. A second motor 49 is fixedly connected to the outside of the gear cover 48. The power output end of the second motor 49 passes through the gear cover 48 and is connected in a transmission manner to the driven gear 51. The driven gear 51 is meshed and connected in a transmission manner with one of the drive gears 50.

[0055] By setting the drive gear 50, it is possible to ensure that the two sets of blades 17 rotate in a consistent and synchronous manner, thus ensuring stable operation of the equipment and guaranteeing the crushing effect.

[0056] In this embodiment, initially, the operator connects the power supply and control system of this patent, injects clean water into the cleaning tank 33, and ensures that the liquid level is below the metal mesh belt 35. At the same time, the heater 47 is started for preheating, and then the high-pressure blower 43 is started to blow air into the housing 10 through the blower hood 41.

[0057] When in use, the second motor 49 is started, and through the transmission of the driven gear 51, the two driving gears 50 are driven to move, which in turn drives the two sets of blades 17 to move in opposite directions at the same speed. Through the meshing transmission of the synchronous gear 21 and the synchronous gear ring 22, the corresponding first cutter shaft 16 drives the corresponding cylinder 15 to rotate synchronously, and the rotation speed of the first cutter shaft 16 and the cylinder 15 is the same. Due to the eccentric setting of the cylinder 15 and the first cutter shaft 16, the blades 17 continuously slide and extend and retract in the cutter groove 18, and the blades 17 completely extend out of the cutter groove 18 between the two cylinders 15.

[0058] Subsequently, the operator feeds the scrap material to be processed into the housing 10 from the hopper 12. The scrap material enters between the two sets of blades 17 and is crushed by the high-speed rotating blades 17. Long strips of scrap material are prone to getting tangled on the surface of the blades 17. As the blades 17 continuously extend and slide within the groove 18, the brush 19 continuously scrapes and sweeps the surface of the blades 17 as they retract into the groove 18, effectively removing the scrap material tangled on the blades 17. Furthermore, since the blades 17 have an inwardly curved cutting edge, it is easy for the tangled scrap material to detach from the blades 17. When the blades 17 extend again, the tip of the blades 17 can pierce the scrap material covering the outside of the groove 18, thus effectively preventing the rotating parts from jamming and being damaged due to the scrap material getting tangled.

[0059] While crushing, the rotation of the cylinder 15 will synchronously drive the cutter 26 and the second cutter shaft 25 to rotate because the groove 23 meshes with the cutter 26. The blade of the cutter 26 will continuously cut into the corresponding groove 23. Even if some long strips of waste are wrapped around the outside of the cylinder 15, the cutter 26 can effectively cut the waste, avoiding entanglement while also crushing the waste.

[0060] During the process of crushing waste, the dust adhering to the surface of the waste and the fine fibers generated when the cloth is torn are carried by the airflow blown out of the blower hood 41 and finally intercepted by the first filter element 29 through the vent 30. This achieves preliminary cleaning of the waste in advance, effectively improving the cleaning effect and ensuring the quality of the final product.

[0061] The crushed waste gradually falls through the holes 14 onto the surface of the metal mesh belt 35. At the same time, the water pump 38 is started, continuously drawing clean water from the bottom of the cleaning tank 33 into the spray pipe 31, and spraying water from the nozzle 32 onto the crushed waste for thorough cleaning, removing oil stains and other contaminants from the waste, ensuring the cleanliness of the waste and facilitating subsequent recycling. Excess water falls back into the bottom of the cleaning tank 33 through the mesh of the metal mesh belt 35, and is then drawn into the second motor 49 by the water pump 38. Meanwhile, the mixed impurities are filtered and collected by the second filter element 40.

[0062] At the same time, the first motor 36 is started to drive the metal mesh belt 35 to operate, so that the metal mesh belt 35 continuously transports the cleaned waste to the drying box 44. The waste eventually falls onto the surface of the metal mesh 46, and the heat generated by the heater 47 is used to dry the waste on the surface of the metal mesh 46, realizing one-stop to obtain dry and clean waste fragments, saving processes and improving recycling efficiency. Finally, the operator can pull out and open the drawer 45 to collect the dried waste for subsequent recycling processing.

[0063] The aforementioned second motor 49, first motor 36, water pump 38, high-pressure blower 43, etc., are mature existing technologies, and are only shown in the attached drawings. They will not be described in detail here.
