Description

Technical Field

[0001] This utility model relates to the field of polyester printed fabric raw material drying technology, and more specifically, it relates to a raw material drying device for polyester printed fabric production. Background Technology

[0002] In existing technologies, the raw material drying device for polyester printed fabric production is a key piece of equipment in the textile industry production chain. Its performance directly affects the production efficiency, quality stability, and energy consumption level of polyester printed fabric. However, the drying devices currently on the market still have many shortcomings in terms of technical implementation and functional design, which restricts the optimization and improvement of the overall production process.

[0003] Firstly, the polyester printed fabric production industry typically uses a simple natural air-drying method to process raw materials, which involves directly exposing the processed, moist raw materials to the natural environment for drying. While this method has low initial investment costs and is simple to operate, it has significant technical drawbacks: First, the natural air-drying process is highly dependent on natural conditions such as ambient temperature, humidity, and airflow intensity, making it impossible to precisely control the drying time. In seasons with high humidity or low temperatures, the drying cycle may be extended several times, severely impacting the efficiency of production planning. Second, due to the instability of environmental factors, the degree of drying varies significantly between different batches of raw materials, leading to inconsistent color adsorption performance in subsequent printing processes and affecting the stability of product quality. Third, during the natural air-drying process, the raw materials are exposed to an open environment, making them prone to adsorbing dust, bacteria, and other impurities from the air, reducing the purity of the product. In addition, open-air drying occupies a large amount of factory space, increasing production site costs, and cannot form a continuous, automated production process, increasing manual intervention and material transfer links. This inefficient drying method with high uncontrollability not only extends the overall production cycle and reduces equipment utilization but also increases the difficulty of quality control.

[0004] Secondly, with the development of industry technology, some companies have adopted mechanized drying equipment to replace traditional natural air drying. However, the existing mechanized drying equipment has a relatively simple and crude pipeline structure design, forming a drying system with fixed parameters. The main drawback of this design is that the input speed of the drying air is a fixed preset value and cannot be dynamically adjusted. This makes it impossible to adjust the airflow intensity according to actual needs when processing polyester raw materials with different materials, fiber densities, and moisture contents. At the same time, in the polyester printed fabric production process, different processes such as pretreatment, dyeing, and printing have different requirements for the degree and rate of drying of raw materials. The fixed-speed drying equipment cannot adapt to this process diversity. In addition, during the production process, factors such as seasonal changes in ambient temperature and humidity, differences in the scale of production batches, and fluctuations in energy costs all require the drying system to have the ability to adjust flexibly. The fixed-speed system obviously cannot meet this requirement. This design defect, which cannot flexibly adapt and adjust the input speed of the drying air according to actual usage needs and process characteristics, cannot ensure the consistent quality of different batches of products. Even when processing special materials, excessively strong or weak airflow may cause damage to the raw material structure or insufficient drying, seriously affecting product quality and production efficiency.

[0005] Furthermore, while a few technologically improved drying devices on the market have achieved adaptive adjustments to the drying air input speed through the coordination of some components, their structural design remains relatively simple, resulting in low overall stability and numerous challenges in actual operation. Firstly, these adjustment mechanisms lack a locking design, making them prone to loosening during prolonged operation. During drying system operation, significant air pressure fluctuations occur within the pipeline, especially at the moment the fan starts and stops. This air pressure impact can cause uneven stress on the adjustment components, gradually leading to slight displacement. Additionally, accidental contact by operators or other external forces can alter the position of finely adjusted components. This lack of structural stability directly impacts performance: the adjusted drying air input speed may undergo unpredictable changes during actual operation, causing fluctuations in drying intensity and inconsistent drying levels across different batches of raw materials. This affects the color adhesion and pattern accuracy of subsequent printing processes, negatively impacting product consistency and equipment lifespan, and failing to meet the basic requirements of the modern textile industry for high-precision, high-efficiency, and high-stability drying devices. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the problems existing in the prior art, this utility model provides a raw material drying device for the production of polyester printed fabric, so as to solve the technical problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a raw material drying device for polyester printed fabric production, comprising a drying chamber, a fan detachably mounted on one side of the drying chamber, a conveying pipe connected to the output end of the fan, a distribution pipe detachably connected to one side of the conveying pipe, an adjusting sleeve rotatably connected to the other end of the distribution pipe, a connecting pipe rotatably connected to the other end of the adjusting sleeve, a positioning frame fixedly mounted on one side of the adjusting sleeve, a positioning rod slidably mounted in the positioning frame, a positioning plate fixedly connected to one end of the positioning rod, and a movable sleeve on the outside of the positioning rod. A connecting spring is provided, with its two ends connected to a positioning plate and a positioning frame, respectively. An adjusting plate is movably provided inside the adjusting sleeve, and a movable shaft and an adjusting shaft are rotatably mounted on the adjusting plate. An adjusting groove is provided on one side of the distribution pipe, and one end of the adjusting shaft on one side of the adjusting plate slides in the adjusting groove. The adjusting plate is rotatably connected to the adjusting sleeve through the movable shaft on the other side. A positioning sleeve is provided on the outside of the connecting pipe, and the inner wall of the positioning sleeve is movably connected to the outer wall of the connecting pipe through threads. Multiple positioning grooves are provided on the outside of the connecting pipe, and one end of the positioning rod is inserted into the positioning groove.

[0010] The present invention is further configured such that a distribution chamber is detachably provided in the drying chamber, and multiple nozzles are detachably connected to one side of the distribution chamber, with two sets of nozzles facing each other. One end of the connecting pipe passes through the side wall of the drying chamber and is connected to the input end of the distribution chamber. An exhaust pipe is connected to the side wall of the drying chamber. Through the design of the distribution chamber and the two sets of nozzles facing each other, uniform drying of polyester printed fabric is achieved, improving drying efficiency and uniformity. At the same time, the exhaust pipe ensures that the moisture generated during the drying process can be discharged in time, preventing moisture from circulating in the drying chamber and affecting the drying effect.

[0011] The present invention is further configured such that a support frame is detachably provided at the top of the drying chamber, an input roller is rotatably mounted on the support frame, an output roller is rotatably mounted on the outside of the drying chamber, and multiple mounting frames are detachably provided on the inside of the drying chamber, with guide rollers rotatably mounted in the mounting frames. This roller system design constructs an orderly and continuous fabric conveying path, enabling the polyester printed fabric to pass through the drying chamber smoothly and orderly, ensuring uniform tension of the fabric during the drying process, and avoiding wrinkles and deformation.

[0012] The present invention is further provided that a filter plate is detachably installed at the input end of the fan. The filter plate can effectively block and filter dust and foreign objects in the outside air, prevent them from entering the pipe and contaminating the polyester printed fabric, and ensure the purity of the dry air.

[0013] The present invention is further configured such that a side cover is detachably provided on one side of the drying chamber, and an observation window is provided on the side cover. The detachable design of the side cover facilitates the installation and removal of the polyester printed fabric, while the setting of the observation window allows the operator to observe the status of the fabric in real time during the drying process and promptly detect and deal with any problems that may arise.

[0014] The present invention is further configured such that the mixing plate has a plurality of mixing holes.

[0015] The present invention is further provided that multiple anti-slip strips are fixedly connected to the outer sides of both the locking sleeve and the adjusting sleeve. The anti-slip strips enhance the friction of the outer surfaces of the locking sleeve and the adjusting sleeve, improve the operating feel and accuracy, and enable the operator to easily and accurately complete the flow rate adjustment and locking operations.

[0016] The present invention is further configured such that one end of the locking rod and the edge of the inner wall of the locking groove are both designed with rounded corners. The rounded corner design allows the locking rod to slide smoothly into and out of the locking groove, reducing wear and impact between components and ensuring smooth operation.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a raw material drying device for polyester printed fabric production, which has the following beneficial effects:

[0019] 1. By combining a drying chamber, distribution bin, nozzles, support frame, input roller, output roller, and multiple mounting frames and guide rollers, this design effectively solves the problems of low efficiency and high uncontrollability associated with simple natural air drying in existing technologies. This design allows the polyester printed fabric to sequentially pass over the input roller, guide rollers, and output roller along a preset path, forming an orderly and continuous transmission path, thus achieving automated fabric conveying. During the conveying process, air drawn in by a fan is filtered through a filter plate and then transported to the distribution bin via a conveying pipe, distribution pipe, adjusting sleeve, and connecting pipe. The air is then evenly sprayed out by oppositely positioned nozzles to dry the polyester printed fabric. This structural design not only overcomes the dependence of traditional natural air drying on environmental conditions but also... The drying process can be carried out in a closed and controlled environment, greatly improving drying efficiency and accuracy. Simultaneously, the exhaust pipes on the side wall of the drying chamber allow the treated air to be discharged or collected, ensuring a clean working environment and preventing contamination of raw materials by dust and other impurities during drying. Furthermore, the entire drying process forms a continuous and automated production flow, significantly reducing manual intervention and material transfer, saving factory space, lowering production costs, improving equipment utilization, shortening the overall production cycle, effectively enhancing the stability of the drying process, ensuring the consistency of drying across different batches of raw materials, and ultimately improving the uniformity of color adsorption and the stability of product quality in subsequent printing processes.

[0020] 2. Through the ingenious coordination of components such as the adjusting sleeve, dispensing plate, movable shaft, dispensing groove, and dispensing holes, a flexible and adjustable drying air input velocity regulation system is constructed. This effectively overcomes the shortcomings of existing mechanized drying devices that cannot adjust the drying air input velocity according to actual usage requirements and process characteristics. The core of this system lies in rotating the adjusting sleeve to drive the movable shaft connected to the inner side to rotate, causing the movable shaft to move the dispensing plate. This, in turn, causes the dispensing shaft on the dispensing plate to slide along the dispensing groove on the distribution pipe. Simultaneously, multiple dispensing holes on the dispensing plate move outward. The movement of the dispensing holes and the outward diffusion of the dispensing plate increase the flow area of ​​the distribution pipe, thereby achieving precise adjustment of the drying air input velocity. This design allows operators to... Based on the characteristics of polyester raw materials with different materials, fiber densities, and moisture contents, the airflow intensity can be flexibly adjusted to provide the most suitable drying conditions for different materials. At the same time, it can adapt to the different requirements of drying degree and drying rate in different processes such as pretreatment, dyeing, and printing in the production process of polyester printed fabric. It can also be flexibly adjusted according to factors such as seasonal changes in ambient temperature and humidity, differences in production batch scale, and fluctuations in energy costs. This flexible adaptability not only ensures the consistent quality of different batches of products, but also avoids the problem of raw material structure damage or insufficient drying caused by excessively strong or weak airflow, significantly improving product quality and production efficiency, and enabling the equipment to meet the high standard requirements of modern polyester printed fabric production for the flexibility of the drying system.

[0021] 3. A highly reliable flow rate regulation and locking system is constructed by precisely coordinating multiple locking components, including a locking sleeve, locking frame, locking rod, locking plate, locking spring, and locking groove. This solves the problem of insufficient stability in the existing improved drying device's regulating mechanism. The locking system ensures stable drying air input flow rate after adjustment through a multi-layered protection mechanism: First, after adjusting to a suitable input flow rate, the locking spring resets and pulls the locking plate inward, causing the locking plate to move the locking rod inward, inserting one end of the locking rod into the corresponding locking groove, forming a preliminary lock. Second, by rotating the locking sleeve in the opposite direction, the locking sleeve moves and resets along the thread on the outer wall of the connecting pipe, causing the inner wall of the locking sleeve to limit the movement of the outer wall of the locking plate, preventing the locking plate and locking rod from colliding. Slide outwards; finally, the locking rod and locking groove cooperate to limit the locking frame, preventing the locking frame and adjusting sleeve from moving or rotating; making the adjustment operation more precise and controllable. This multi-locking structure can effectively resist the influence of external factors such as air pressure fluctuations inside the pipeline during the operation of the drying system, air pressure impact inside the pipeline at the moment of fan start-up and shutdown, and accidental contact by operators on the adjusting components, ensuring that the adjusted drying air input flow rate remains stable during actual operation, thereby ensuring the consistency of drying intensity, making the drying degree of different batches of raw materials consistent, improving the color adhesion and pattern accuracy of subsequent printing processes, extending the service life of equipment, and fully meeting the basic requirements of the modern textile industry for high-precision, high-efficiency, and high-stability drying devices.

[0031] Please see Figures 1-5 A raw material drying device for polyester printed fabric production includes a drying chamber 1. A fan 2 is detachably mounted on one side of the drying chamber 1. A conveying pipe 3 is connected to the output end of the fan 2. A distribution pipe 4 is detachably connected to one side of the conveying pipe 3. An adjusting sleeve 5 is rotatably connected to the other end of the distribution pipe 4. A connecting pipe 6 is rotatably connected to the other end of the adjusting sleeve 5. A positioning frame 7 is fixedly installed on one side of the adjusting sleeve 5. A positioning rod 8 is slidably mounted in the positioning frame 7. A positioning plate 9 is fixedly connected to one end of the positioning rod 8. A connecting spring 10 is movably sleeved on the outside of the positioning rod 8. The two ends of the connecting spring 10 are respectively connected to the positioning plate 9 and the positioning plate 9. The positioning frame 7 is connected, and the adjusting sleeve 5 is movably provided with a dispensing plate 11. The dispensing plate 11 is rotatably mounted with a movable shaft 12 and a dispensing shaft 13. A dispensing groove 14 is opened on one side of the dispensing pipe 4. One end of the dispensing shaft 13 on one side of the dispensing plate 11 slides in the dispensing groove 14. The dispensing plate 11 is rotatably connected to the adjusting sleeve 5 through the movable shaft 12 on the other side. A positioning sleeve 15 is provided on the outside of the connecting pipe 6. The inner wall of the positioning sleeve 15 is movably connected to the outer wall of the connecting pipe 6 through threads. Multiple positioning grooves 16 are opened on the outside of the connecting pipe 6. One end of the positioning rod 8 is inserted into the positioning groove 16.

[0032] The drying chamber 1 is detachably equipped with a distribution chamber 17. Multiple nozzles 18 are detachably connected to one side of the distribution chamber 17, and two sets of nozzles 18 are arranged facing each other. One end of the connecting pipe 6 passes through the side wall of the drying chamber 1 and is connected to the input end of the distribution chamber 17. An exhaust pipe 19 is connected to the side wall of the drying chamber 1.

[0033] The top of the drying chamber 1 is detachably provided with a support frame 20, on which an input roller 21 is rotatably mounted. An output roller 22 is rotatably mounted on the outside of the drying chamber 1. Multiple mounting frames 23 are detachably provided on the inside of the drying chamber 1, and guide rollers 24 are rotatably mounted in the mounting frames 23.

[0034] A filter plate 25 can be detachably installed at the input end of the fan 2.

[0035] The drying oven 1 has a detachable side cover 26 on one side, and an observation window 27 is provided on the side cover 26.

[0036] In this embodiment, when the equipment is needed, firstly, the take-up roller with the polyester printed fabric to be dried wound around it is installed on the external mounting frame. Then, the side cover 26 is removed. Next, the polyester printed fabric is wound around the input pipe, each guide roller 24, and finally around the output roller 22 as shown in the figure, so that one end of the polyester printed fabric is fixed in the external take-up device. Then, the side cover 26 is reinstalled on one side of the drying chamber 1. Then, the fan 2 is turned on, and the fan 2 draws in outside air. The filter plate 25 can effectively block and filter dust and foreign objects, preventing foreign objects and dust from entering the pipe. The air is drawn in by the blower 2 and then transported to two distribution pipes 4 through the conveying pipe 3 connected to the output end. Then, it is transported to two distribution chambers 17 through the adjusting sleeve 5 and the connecting pipe 6. The air is then sprayed out through multiple nozzles 18 connected to one side of the distribution chamber 17 to achieve the drying treatment of the polyester printed fabric. At the same time, the external winding device is turned on so that the external winding device can wind up the polyester printed fabric. The air entering the drying chamber 1 will eventually be discharged through the exhaust pipe 19 set on the side wall of the drying chamber 1, or through the external collection device connected to the exhaust pipe 19 to further treat the discharged air before it is discharged.

[0037] Please see Figures 3-5 As a further implementation of the overall equipment: the mixing plate 11 has multiple mixing holes 28.

[0038] Multiple anti-slip strips 29 are fixedly connected to the outer sides of both the locking sleeve 15 and the adjusting sleeve 5.

[0039] Both the end of the locking rod 8 and the inner edge of the locking groove 16 adopt a rounded corner structure design.

[0040] More specifically, when the input flow rate of the drying air needs to be adjusted, firstly, rotate the locking sleeve 15 in the forward direction, causing it to move along the threaded outer wall of the connecting pipe 6. Then, the inner wall of the locking sleeve 15 no longer limits the outer wall of the locking plate 9. Next, rotate the adjusting sleeve 5 in the forward direction. The adjusting sleeve 5 will drive one side of the locking frame 7 to rotate in the forward direction. Then, the locking frame 7 will drive the locking rod 8, the connecting spring 10, and the locking plate 9 to rotate in the forward direction. Then, the inner wall of the locking groove 16 will press against one end of the locking rod 8. Due to the pressure between one end of the locking rod 8 and the edge of the inner wall of the locking groove 16... The design incorporates a rounded corner structure. One end of the locking rod 8 slides out of the locking groove 16, while the other end of the locking rod 8 drives the locking plate 9 to slide outwards. This causes the locking plate 9 to stretch the connecting spring 10 outwards. Simultaneously, the adjusting sleeve 5 drives the inner connected movable shaft 12 to rotate. The movable shaft 12 then drives the dispensing plate 11 to move, causing the dispensing plate 11 to drive the dispensing shaft 13, which is rotatably connected on the other side, to slide outwards along the dispensing groove 14. This, in turn, causes the dispensing plate 11 to move multiple dispensing holes 28 outwards. The movement of the dispensing holes 28... The outward diffusion of the distribution plate 11 expands the flow area of ​​the distribution pipe 4, thereby adjusting the input flow rate of the drying air. When the appropriate input flow rate is reached, the rotation of the adjusting sleeve 5 is stopped, and the locking frame 7 drives the locking rod 8 and other components to rotate to the position corresponding to the locking slot 16. Then, the connecting spring 10 resets and pulls the locking plate 9 to slide inward, causing the locking plate 9 to drive the locking rod 8 to slide inward, so that one end of the locking rod 8 is inserted into the corresponding locking slot 16. Then, the locking sleeve 15 is rotated in the opposite direction, so that the locking sleeve 15 moves along the connecting... The threads on the outer wall of pipe 6 are moved and reset, so that the inner wall of the locking sleeve 15 limits the outer wall of the locking plate 9 again, preventing the locking plate 9 and the locking rod 8 from sliding outward. Then, the locking rod 8 and the locking groove 16 cooperate to limit the locking frame 7, so that the locking frame 7 and the adjusting sleeve 5 will not move or rotate, thus ensuring the structural stability after the dry air input flow rate is adjusted, and thus ensuring the stable input of dry air. The anti-slip strip 29 improves the anti-slip ability of the outer surface of the locking sleeve 15 and the adjusting sleeve 5, and improves the operating feel, making the operation more precise.

[0041] In summary, when using or operating the equipment: First, install the take-up roller with the polyester printed fabric to be dried on the external mounting bracket. Then, remove the side cover 26. Next, pass the polyester printed fabric around the input pipe, each guide roller 24, and finally around the output roller 22 as shown in the diagram, ensuring one end of the polyester printed fabric is fixed in the external take-up device. Then, reinstall the side cover 26 on one side of the drying chamber 1. Then, turn on the fan 2, which draws in outside air. The filter plate 25 effectively blocks and filters dust and foreign objects, preventing them from entering. The air is drawn into the pipe by the blower 2 and then transported to two distribution pipes 4 through the conveying pipe 3 connected to the output end. Then, it is transported to two distribution chambers 17 through the regulating sleeve 5 and the connecting pipe 6. The air is then sprayed out through multiple nozzles 18 connected to one side of the distribution chamber 17 to achieve the drying treatment of the polyester printed fabric. At the same time, the external winding device is turned on so that the external winding device can wind up the polyester printed fabric. The air that enters the drying chamber 1 will eventually be discharged through the exhaust pipe 19 set on the side wall of the drying chamber 1, or through the external collection device connected to the exhaust pipe 19 to further treat the discharged air before it is discharged.

[0042] When the input flow rate of the drying air needs to be adjusted, first rotate the locking sleeve 15 forward, so that the locking sleeve 15 moves along the thread on the outer wall of the connecting pipe 6, so that the inner wall of the locking sleeve 15 no longer limits the outer wall of the locking plate 9. Then rotate the adjusting sleeve 5 forward, which will drive one side of the locking frame 7 to rotate forward. Then the locking frame 7 will drive the locking rod 8, the connecting spring 10 and the locking plate 9 to rotate forward. Then the inner wall of the locking groove 16 will press against one end of the locking rod 8. Due to the rounded corner structure at the edge of the inner wall of the locking groove 16, the locking rod 8 is pressed against one end of the locking rod 8. The design involves the locking rod 8 sliding out of the locking groove 16 at one end, and the locking plate 9 sliding outward at the other end. This causes the locking plate 9 to stretch the connecting spring 10 outward. Simultaneously, the adjusting sleeve 5 rotates the inner connected movable shaft 12, which in turn moves the dispensing plate 11. This causes the dispensing plate 11 to slide outward along the dispensing groove 14, along with the dispensing shaft 13 connected to the other side. The dispensing plate 11 then moves multiple dispensing holes 28 outward. The movement of the dispensing holes 28 and the dispensing plate... The outward diffusion of 11 expands the flow area of ​​the distribution pipe (4), thereby adjusting the input flow rate of the drying air. When the appropriate input flow rate is adjusted, the rotation of the adjusting sleeve 5 is stopped, and the positioning frame 7 drives the positioning rod 8 and other components to rotate to the position corresponding to the corresponding positioning groove 16. Then the connecting spring 10 resets and pulls the positioning plate 9 to slide inward, so that the positioning plate 9 drives the positioning rod 8 to slide inward, so that one end of the positioning rod 8 is inserted into the corresponding positioning groove 16. Then the positioning sleeve 15 is rotated in the opposite direction, so that the positioning sleeve 15 moves along the connecting pipe. The threads on the outer wall of the 6th ring are moved and reset, so that the inner wall of the locking sleeve 15 limits the outer wall of the locking plate 9 again, preventing the locking plate 9 and the locking rod 8 from sliding outward. Then, the locking rod 8 and the locking groove 16 cooperate to limit the locking frame 7, so that the locking frame 7 and the adjusting sleeve 5 will not move or rotate, thus ensuring the structural stability after the dry air input flow rate is adjusted, and thus ensuring the stable input of the dry air. The anti-slip strip 29 improves the anti-slip ability of the outer surface of the locking sleeve 15 and the adjusting sleeve 5, and improves the operating feel, making the operation more precise.

For all the fixed connections mentioned above, welding is preferred.
