Description

Technical Field

[0001] The present application relates to the field of drying technology, and more specifically, to a drying device for flax fiber production. Background Art

[0002] The flax fiber production drying device is a device used in the flax fiber production process to dry wet flax fibers after degumming and other treatments. It removes moisture from the fibers through heating and ventilation to achieve the dryness required for subsequent processing, which can effectively improve the quality and production efficiency of flax fibers.

[0003] Traditional drying methods rely primarily on a single hot air cycle, which is inefficient for removing moisture from flax fibers. Due to the inherent flexibility and intertwining nature of flax fibers, fiber clumps easily form during the drying process, hindering rapid evaporation of internal moisture. This significantly prolongs drying time and increases energy consumption. Hot air often only acts on the surface of the fiber clumps, failing to penetrate deep into the fibers, leading to uneven drying. This not only affects the drying quality of the flax fibers, resulting in inconsistent product quality, but also creates numerous inconveniences during subsequent processing.

[0004] In view of this, the present application proposes a flax fiber production and drying device. Utility Model Content

[0007] Optionally, the bottom of the grid frame is connected to a threaded cover by a threaded rotation, a fixed plate is fixedly connected to one side of the upper interior of the grid frame, the upper end surface of the fixed plate is fixedly connected to a connecting block, and the connecting block is rotatably connected to the upper interior of the drying cylinder.

[0008] Optionally, end surfaces of the two extruded strips that are away from each other are each provided with a mounting groove, and ends of the two extruded strips that are away from each other are each provided with a top plate.

[0009] Optionally, a plurality of springs are fixedly connected to the interior of the mounting groove, and one end of the spring is fixedly connected to the top plate, and the top plate is tightly fitted to the inner wall of the drying cylinder.

[0010] Optionally, limiting grooves are symmetrically provided inside the fixing plate, one side of the upper end surface of the extrusion strip is fixedly connected to a limiting block, and the limiting block is located inside the limiting groove.

[0013] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0014] The present invention utilizes a mesh frame to rotate, driving the extrusion bar and the limiting block to rotate synchronously. When the limiting block moves along the inclined surface of the fixed bar, the extrusion bar generates periodic relative motion, continuously squeezing the flax fibers within the mesh frame. This squeezing action effectively squeezes out moisture from the flax fibers, further accelerating the drying process and reducing the time and energy consumption required for hot air drying alone. Simultaneously, the reciprocating movement of the extrusion bar also serves to loosen the flax fibers. Through the dual effects of rotation and squeezing, flax fibers that might otherwise clump or tangle are broken up, allowing each fiber to be more fully exposed to the hot air, further increasing the contact area between the fibers and the hot air, and improving the comprehensiveness and uniformity of drying. This helps improve the final quality of the flax fibers, making them easier to handle during subsequent processing, and enhancing the consistency and effectiveness of the entire flax fiber production process.

[0019] The present application is further described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1-Figure 3 The embodiment of the present application provides a drying device for producing flax fibers, comprising a drying cylinder 1 and a heating mechanism for drying flax fibers. A pair of fixing bars 11 are fixedly connected to the upper portion of the drying cylinder 1. A holding mechanism is provided inside the drying cylinder 1, and the holding mechanism can fully dry the flax fibers by rotating. The holding mechanism includes a mesh frame 7 that is rotatably connected and passes through the lower portion of the drying cylinder 1. Sliding grooves 13 are symmetrically formed on the outer wall of the mesh frame 7. Extrusion bars 14 are slidably connected to the inner portion of the sliding grooves 13. The mesh frame 7 structure can both support the flax fibers and facilitate the circulation of hot air between the fibers. Its grid-like design allows hot air to penetrate the fiber layer from multiple directions, increasing the contact area between the fibers and the hot air, ensuring uniform heating of the flax fibers, and avoiding local over-drying or under-drying. This effectively ensures the consistency of the drying quality of the flax fibers and improves the overall quality of the product.

[0021] The bottom of the grid frame 7 is rotatably connected to a threaded cap 8. A fixing plate 9 is fixedly connected to one side of the upper interior of the grid frame 7. A connecting block 10 is fixedly connected to the upper end face of the fixing plate 9. The connecting block 10 is rotatably connected to the upper interior of the drying cylinder 1. A servo motor 2 is fixedly connected to the upper end face of the drying cylinder 1. The output end of the servo motor 2 is fixedly connected to the connecting block 10. A feed port 3 is formed through one side of the upper end face of the drying cylinder 1. The provision of the threaded cap 8 makes it extremely convenient to remove the flax fibers after drying. Simply turning the threaded cap 8 to open it allows the dried flax fibers in the grid frame 7 to be easily poured out, making it easy to clean the grid frame 7 and prepare for drying the next batch of flax fibers. The entire operation process is efficient and smooth, reducing equipment downtime and helping to improve production continuity.

[0022] The end surfaces of the two extrusion strips 14 that are away from each other are each provided with a mounting groove 15, and the ends of the two extrusion strips 14 that are away from each other are each provided with a top plate 16. A plurality of springs 17 are fixedly connected to the interior of the mounting groove 15, and one end of the spring 17 is fixedly connected to the top plate 16. The spring 17 plays a good elastic supporting role, so that the top plate 16 is always close to the inner wall of the drying cylinder 1.

[0023] The top plate 16 fits tightly against the inner wall of the drying cylinder 1, and the limiting grooves 12 are symmetrically provided inside the fixed plate 9. One side of the upper end surface of the extrusion bar 14 is fixedly connected to the limiting block 18, and the limiting block 18 is located inside the limiting groove 12. The rotation of the grid frame 7 drives the extrusion bar 14 and the limiting block 18 to rotate synchronously. When the limiting block 18 moves along the inclined surface of the fixed bar 11, the extrusion bar 14 produces a periodic relative motion, continuously squeezing the flax fibers in the grid frame 7. The squeezing action can effectively squeeze out the moisture inside the flax fibers, further accelerating the drying process and reducing the time and energy consumption required for drying by hot air alone.

[0024] At the same time, the reciprocating movement of the squeezing bars 14 also serves to loosen the flax fibers. Through the dual effects of rotation and squeezing, the flax fibers that might otherwise clump or tangle are broken up, allowing each fiber to be more fully exposed to the hot air. This further increases the contact area between the fibers and the hot air, improving the comprehensiveness and uniformity of the drying process, which in turn improves the final quality of the flax fibers, making them easier to handle in subsequent processing, and enhancing the consistency and effectiveness of the entire flax fiber production process.

[0025] Reference Figure 2 The heating mechanism includes a ventilation frame 4 fixedly connected to one side of the outer wall of the drying cylinder 1. The drying cylinder 1 is connected to the ventilation frame 4, and the top plate 16 is longer than the ventilation frame 4. A fan group 5 is fixedly connected to the interior of the ventilation frame 4, and a heater 6 is fixedly connected to one side of the interior of the ventilation frame 4. The heater 6 cooperates with the fan group 5 to quickly and evenly distribute heat within the drying cylinder 1, providing a stable and sufficient source of heat energy for the flax fibers in the grid frame 7. This heating method allows the flax fibers to heat up rapidly in a suitable high-temperature environment, accelerating moisture evaporation, significantly improving the drying speed, and reducing the overall drying time, thereby improving production efficiency and meeting the needs of large-scale flax fiber production.

[0026] Working principle: When in use, the staff will pour the flax fibers to be dried into the grid frame 7 through the feed port 3 and the fixed plate 9. The staff will first start the fan group 5 and heater 6 inside the ventilation frame 4. The heater 6 releases heat, and the fan group 5 blows the heat into the drying cylinder 1, thereby drying and heating the flax fibers inside the grid frame 7.

[0027] The servo motor 2 is started, and the servo motor 2 drives the output end to rotate. The rotation of the output end drives the connecting block 10 to rotate. The rotation of the connecting block 10 drives the grid frame 7 and the flax fibers inside the grid frame 7 to rotate synchronously. The extrusion bars 14 and the top plate 16 on both sides of the grid frame 7 rotate synchronously. Since the limit blocks 18 on the extrusion bars 14 are always tightly fitted with the fixed bars 11 above the inside of the drying cylinder 1, the multiple springs 17 between the extrusion bars 14 and the top plate 16 are always in a tightened state, and generate elastic force to make the top plate 16 always close to the inner wall of the drying cylinder 1. During the rotation of the grid frame 7, the position of the fixed bar 11 remains unchanged, and the limiting block 18 will move along the inclined surface of the fixed bar 11, so that the two limiting blocks 18 move away from each other. The movement of the two limiting blocks 18 drives the two squeezing bars 14 to move. When the limiting block 18 passes the top of the fixed bar 11, the two limiting blocks 18 will gradually approach each other in the limiting groove 12, so that the two squeezing bars 14 gradually approach each other. After the two squeezing bars 14 approach each other, they will squeeze the flax fibers inside the grid frame 7, thereby squeezing out the moisture inside the flax fibers. The flax fibers can be broken up by the continuous reciprocating movement of the two squeezing bars 14 to squeeze the flax fibers, so that the rotating flax fibers can be more fully exposed to hot air, thereby improving the drying efficiency of the flax fibers and making the drying more comprehensive.

[0028] After the drying is completed, the electrical appliances are turned off, the screw cap 8 below the grid frame 7 is rotated to open, the screw cap 8 below the grid frame 7 is taken out, and the flax fibers inside the grid frame 7 are taken out.

[0029] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
