Description

Technical Field

[0001] This utility model relates to the field of yarn drying equipment, and more particularly to a drying device for flocked yarn. Background Technology

[0002] In the textile industry, flocked yarn is widely used in clothing, home textiles, handicrafts and other fields due to its unique soft touch, rich colors and good decorative properties; and drying is a key step in the flocked yarn production process, the efficiency and quality of which directly affect the quality of the final product.

[0003] Currently, common flocked yarn drying devices on the market typically consist of a dryer body, a heating system, and a ventilation system. During the drying process, the flocked yarn surface is relatively fluffy, which easily produces lint. This lint not only disperses with the airflow during the drying process, polluting the production environment and posing a potential threat to the health of operators, but also adheres to various components inside the drying device, affecting the normal operation and service life of the device.

[0004] Most existing drying equipment uses a fixed filter structure to intercept lint. However, as lint accumulates, the filter plate will soon become clogged, requiring frequent manual disassembly and cleaning. This not only increases the workload and maintenance costs of operators, but also causes the drying process to be interrupted, affecting production efficiency.

[0005] Therefore, it is necessary to provide a new drying device for flocked yarn to solve the above-mentioned technical problems. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this utility model provides a drying device for flocked yarn.

[0007] The drying device for flocked yarn provided by this utility model includes: a dryer body, a filter plate, a flipping assembly, a cleaning roller, a cleaning assembly, and a suction nozzle. The bottom of the dryer body is connected to an exhaust pipe. The interior of the dryer body is equipped with filter plates for intercepting lint at equal intervals. The filter plates are located below the flocked yarn and parallel to its forward direction. A flipping assembly is installed between the dryer body and the filter plate. The flipping assembly drives the filter plate to flip 180 degrees to alternately intercept the lint generated during the drying process. Cleaning rollers are provided below both ends of the filter plate. A cleaning assembly is installed between the dryer body and the cleaning rollers. The cleaning assembly drives the cleaning rollers to rotate and move closer to each other to clean the lint intercepted on the surface of the filter plate. A suction nozzle is provided below each cleaning roller. The suction nozzle moves synchronously with the cleaning roller to collect the cleaned lint.

[0008] Preferably, the flipping assembly includes: an electric push rod, a connecting rod, a gear 1, and a rack 1. The electric push rod is fixedly connected to the side wall of the dryer body near the feed end. The connecting rod is fixedly connected to the middle of both ends of the filter plate. The opposite ends of the connecting rods are rotatably connected to the inner wall of the dryer body. The end of the connecting rod near the feed end is fixedly connected to a gear 1. The output end of the electric push rod extends into the interior of the dryer body and is fixedly connected to a rack 1. The gear 1 near the feed end is meshed with the rack 1.

[0009] Preferably, the cleaning components include: a motor, a bidirectional threaded rod, a slider, and a limiting rod. The motor is fixedly connected to one end of the dryer body near the feed end. The output end of the motor extends into the interior of the dryer body and is fixedly connected to the bidirectional threaded rod. The other end of the bidirectional threaded rod is rotatably connected to the inner wall of the dryer body. Both ends of the bidirectional threaded rod are threadedly connected to sliders. Limiting holes are opened at the bottom of each slider. A limiting rod is fixedly connected inside the dryer body. The limiting rod is placed inside the limiting hole and is slidably connected to its inner wall.

[0010] Preferably, each slider has a connecting plate fixedly connected to its side wall, the top of each connecting plate is rotatably connected to the corresponding cleaning roller, and the other end of each cleaning roller is slidably connected to the side wall of the dryer body.

[0011] Preferably, the side wall of the dryer body is provided with an installation groove, and a rack is fixedly connected to the inner wall of the installation groove. The cleaning roller is fixedly connected to a gear two at the end near the connecting plate and meshes with the rack two.

[0012] Preferably, each slider has a crossbar fixedly connected to its side wall, and the other end of each crossbar is fixedly connected to a corresponding dust suction nozzle. A suction fan is provided on one side of the dryer body. The output end of the suction fan is connected to a collection bucket through a pipe, and the input end is connected to a corresponding dust suction nozzle through a pipe.

[0013] Preferably, the side wall of the collection bucket is connected to an air outlet, and a filter screen is installed at the connection between the air outlet and the collection bucket.

[0014] Preferably, the outer wall of the cleaning roller is provided with wear-resistant bristles.

[0015] Compared with related technologies, the flocked yarn drying device provided by this utility model has the following beneficial effects:

[0016] The filter plate is rotated 180 degrees by a flipping component, enabling the filter plate to be used alternately. When one side of a filter plate intercepts lint, it flips to the bottom, and the other side flips to the top to continue intercepting lint generated later. This ensures the continuity of lint interception during the drying process, eliminating the need to frequently stop the drying process to clean the filter plate and improving production efficiency.

[0017] By designing the cleaning components, the filter plates are automatically cleaned. Compared with the existing method of using a fixed filter structure that requires frequent manual disassembly and cleaning, the automatic cleaning function of this drying device greatly reduces the workload and maintenance costs of operators, reduces the interruption time in the drying process caused by cleaning the filter plates, and further improves production efficiency.

[0018] A suction nozzle is installed below the cleaning roller, and the suction nozzle moves synchronously with the cleaning roller. When the cleaning roller brushes the lint off the filter plate, the suction fan starts simultaneously, and the suction nozzle generates suction to suck up the lint, which is then collected in a collection bucket through a pipe. This achieves effective collection of lint, prevents the lint from drifting back into the production environment, and ensures the cleanliness of the production environment.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 4 A drying device for flocked yarn includes: a dryer body 1, filter plates 3, a flipping assembly, cleaning rollers 4, a cleaning assembly, and a suction nozzle 5. An exhaust pipe 2 is connected to the bottom of the dryer body 1. Filter plates 3 for intercepting lint are equidistantly arranged inside the dryer body 1. The filter plates 3 are located below the flocked yarn and parallel to its direction of travel. A flipping assembly is installed between the dryer body 1 and the filter plates 3, driving the filter plates 3 to flip 180 degrees to alternately intercept lint generated during the drying process. Cleaning rollers 4 are located below both ends of the filter plates 3. A cleaning assembly is installed between the dryer body 1 and the cleaning rollers 4, driving the cleaning rollers 4 to rotate and move closer together to clean the filter plates. 3. For surface-intercepted lint, each cleaning roller 4 is equipped with a suction nozzle 5. The suction nozzle 5 moves synchronously with the cleaning roller 4 to collect the cleaned lint. The flipping assembly includes: an electric push rod 6, a connecting rod 7, a gear 8, and a rack 9. The electric push rod 6 is fixedly connected to the side wall of the dryer body 1 near the feed end. The middle of both ends of the filter plate 3 is fixedly connected to the connecting rod 7. The opposite ends of the connecting rod 7 are rotatably connected to the inner wall of the dryer body 1. The end of the connecting rod 7 near the feed end is fixedly connected to the gear 8. The output end of the electric push rod 6 extends into the interior of the dryer body 1 and is fixedly connected to the rack 9. The gear 8 near the feed end is meshed with the rack 9. The outer wall of the cleaning roller 4 is equipped with wear-resistant bristles.

[0029] It should be noted that: the dryer body 1 is equipped with a heating system and a ventilation system. The heating system blows hot air from top to bottom. The flocked yarn produces lint under the action of the hot air, which is intercepted by the filter plate 3 set inside the dryer body 1. Then the hot air is discharged through the exhaust pipe 2 connected to the bottom of the dryer body 1.

[0030] Rack 9 is located above gear 8, and the bottom of rack 9 has several segments of teeth, each segment of teeth corresponding to the corresponding gear 8, and its number of teeth is half the number of teeth of gear 8.

[0031] Please see Figure 1 and Figure 4The cleaning components include: a motor 10, a bidirectional threaded rod 11, a slider 12, and a limiting rod 13. The motor 10 is fixedly connected to one end of the dryer body 1 near the feed inlet. The output end of the motor 10 extends into the interior of the dryer body 1 and is fixedly connected to the bidirectional threaded rod 11. The other end of the bidirectional threaded rod 11 is rotatably connected to the inner wall of the dryer body 1. Both ends of the bidirectional threaded rod 11 are threadedly connected to sliders 12, and each slider 12 has a limiting hole at its bottom. The limiting rod 13 is fixedly connected inside the dryer body 1, positioned inside the limiting hole, and slidably connected to its inner wall. Connecting plates are fixedly connected to the side walls of each slider 12, and the tops of the connecting plates are rotated with the corresponding cleaning rollers 4. The cleaning roller 4 is slidably connected to the side wall of the dryer body 1. The side wall of the dryer body 1 is provided with an installation groove. The inner wall of the installation groove is fixedly connected with a rack 14. The end of the cleaning roller 4 near the connecting plate is fixedly connected with a gear 15 and meshes with the rack 14. The side wall of the slider 12 is fixedly connected with a crossbar. The other end of the crossbar is fixedly connected to the corresponding suction nozzle 5. A suction fan 16 is provided on one side of the dryer body 1. The output end of the suction fan 16 is connected to a collection bucket 17 through a pipe, and the input end is connected to the corresponding suction nozzle 5 through a pipe. The side wall of the collection bucket 17 is connected to an air outlet 18, and a filter screen is installed at the connection with the collection bucket 17.

[0032] It should be noted that: when the motor 10 starts, the bidirectional threaded rod 11 begins to rotate, and the slider 12, which is threaded at both ends, begins to move along its axial direction under the action of the limit rod 13. When the slider 12 moves along the bidirectional threaded rod 11, it will drive the cleaning roller 4, which is rotated and connected through the connecting plate, to move synchronously. During the movement of the cleaning roller 4, the gear 15 will mesh with the rack 14, so that the cleaning roller 4 will rotate while moving. The outer wall of the cleaning roller 4 is provided with wear-resistant bristles. During the rotation and movement, the wear-resistant bristles will clean the surface of the bottom of the flipped filter plate 3 and brush off the lint attached to the filter plate 3. At the same time, the suction fan 16 starts, and its input end generates negative pressure, which causes the suction nozzle 5 to generate suction through the pipe, sucking away the lint cleaned off by the cleaning roller 4.

[0033] The working principle of the flocked yarn drying device provided by this utility model is as follows:

[0034] The pre-treated flocked yarn enters the drying area inside the dryer body 1 from the feed end. The dryer body 1 is equipped with a heating system that blows hot air from top to bottom to dry the flocked yarn in the drying area. Because the flocked yarn has fluffy fibers on its surface, the fibers will generate lint during the drying process due to the hot air. These lints will drift inside the dryer body 1 with the airflow during the drying process.

[0035] Multiple filter plates 3 are equidistantly arranged inside the dryer body 1. The filter plates 3 are located below the flocked yarn and are parallel to the forward direction of the flocked yarn. When the lint is dispersed with the airflow, it will be intercepted by the filter plates 3, thereby preventing the lint from further polluting the production environment or adhering to other parts inside the drying device.

[0036] As the drying process continues, the electric push rod 6 is activated according to the preset program; the electric push rod 6 is fixedly connected to the side wall of the dryer body 1 near the feed end, and its output end extends into the interior of the dryer body 1 and is fixedly connected to the rack 9; when the output end of the electric push rod 6 moves, the rack 9 moves accordingly.

[0037] Both ends of the filter plate 3 are fixedly connected to the middle of the connecting rod 7. The opposite ends of the connecting rod 7 are rotatably connected to the inner wall of the dryer body 1. The end of the connecting rod 7 near the feed end is fixedly connected to a gear 8, which meshes with a rack 9. Therefore, when the rack 9 moves, it will drive the gear 8 to rotate 180 degrees, thereby causing the filter plate 3 to rotate 180 degrees around the connecting rod 7 and flip over. In this way, the side that originally intercepted lint flips to the bottom, while the other side flips to the top to continue intercepting the lint generated later. This realizes the alternating use of the filter plate 3 and ensures the continuity of lint interception during the drying process.

[0038] After the filter plate 3 is flipped, the motor 10 starts. The motor 10 is fixedly connected to the end of the dryer body 1 near the feed, and its output end extends into the interior of the dryer body 1 and is fixedly connected to a bidirectional threaded rod 11. The other end of the bidirectional threaded rod 11 is rotatably connected to the inner wall of the dryer body 1. When the motor 10 starts, the bidirectional threaded rod 11 begins to rotate.

[0039] Both ends of the bidirectional threaded rod 11 are threadedly connected to sliders 12. A limiting hole is opened at the bottom of the slider 12. A limiting rod 13 is fixedly connected inside the dryer body 1. The limiting rod 13 is placed inside the limiting hole and is slidably connected to the inner wall of the limiting hole. Under the restriction of the limiting rod 13, the slider 12 can only move along the axial direction of the bidirectional threaded rod 11.

[0040] Each slider 12 has a connecting plate fixedly connected to its side wall. The top of each connecting plate is rotatably connected to the corresponding cleaning roller 4. The other end of each cleaning roller 4 is slidably connected to the side wall of the dryer body 1. When the slider 12 moves along the bidirectional threaded rod 11, it will drive the cleaning roller 4, which is rotatably connected through the connecting plate, to move synchronously.

[0041] The dryer body 1 has a mounting groove on its side wall. A rack 14 is fixedly connected to the inner wall of the mounting groove. A gear 15 is fixedly connected to the end of the cleaning roller 4 near the connecting plate, and the gear 15 meshes with the rack 14. Therefore, when the cleaning roller 4 moves, the gear 15 meshes with the rack 14, causing the cleaning roller 4 to rotate while moving. The outer wall of the cleaning roller 4 is provided with wear-resistant bristles. During the rotation and movement, the wear-resistant bristles clean the surface of the bottom of the flipped filter plate 3 and brush off the lint attached to the filter plate 3.

[0042] The side walls of the slider 12 are also fixedly connected with crossbars, and the other end of each crossbar is fixedly connected to the corresponding vacuum nozzle 5; when the slider 12 moves, it will drive the vacuum nozzle 5 to move synchronously through the crossbars.

[0043] A suction fan 16 is installed on one side of the dryer body 1. The output end of the suction fan 16 is connected to a collection bucket 17 through a pipe, and the input end is connected to a corresponding suction nozzle 5 through a pipe. When the motor 10 starts, the suction fan 16 starts synchronously. When the cleaning roller 4 brushes the lint off the filter plate 3, the input end of the suction fan 16 generates negative pressure, which causes the suction nozzle 5 to generate suction through the pipe, sucking away the lint cleaned off by the cleaning roller 4. The lint is collected in the collection bucket 17 through the pipe.

[0044] The side wall of the collection bucket 17 is connected to the air outlet 18, and a filter screen is installed at the connection between the collection bucket 17 and the air outlet 18. After the airflow drawn in by the suction fan 16 is mixed with lint and enters the collection bucket 17, the airflow is discharged through the air outlet 18, while the lint is intercepted by the filter screen in the collection bucket 17, thus achieving effective collection of lint and preventing lint from drifting into the production environment again.

[0045] When the slider 12 moves to the middle of the bidirectional threaded rod 11, the motor 10 starts to reverse, and the bidirectional threaded rod 11 reverses accordingly. The slider 12 moves in the opposite direction under the restriction of the limit rod 13. During this process, the cleaning roller 4 cleans the bottom surface of the filter plate 3 again to ensure that the lint remaining on the surface of the filter plate 3 is thoroughly cleaned. When the slider 12 is reset, the motor 10 stops working and waits for the start of the next flipping program to perform the cleaning operation again.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
