Description

[0002] Waterproof polyester fabrics are widely used in outdoor apparel technology.

As a key material in the production of outdoor apparel, the quality and performance of waterproof polyester fabrics are directly affected by the quality of their production processes and equipment.

[0003] In existing waterproof polyester fabric production technology, a common practice is to disperse the fabric conveying, drying, and cross-linking baking functions across different equipment or areas. The fabric is first conveyed to the impregnation area using a simple mechanical device. After being impregnated with the waterproofing agent, it is manually transported to a separate drying device for drying. After drying, the fabric must be manually placed in the cross-linking baking equipment for processing. This method makes the production process cumbersome, requires a large space for layout between equipment, and has high equipment connection costs. Moreover, because the operations of each link are relatively independent, the fabric is prone to damage and wrinkles during manual handling, affecting product quality and increasing the risk of failure.

[0022] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Please see the attached Figure 1 -Attached Figure 3 An embodiment of the present invention provides a preparation device for waterproof polyester fabric, including a shell 1, a support leg 2 is fixedly connected to the lower surface of the shell 1, a conveying component 3 is fixedly connected to the right outer wall of the shell 1, a fan 4 is fixedly connected to the upper surface of the conveying component 3, a recovery component 5 is fixedly connected to the outer wall of the shell 1, a water tank 6 is fixedly connected to the upper surface of the shell 1, a support plate 7 is fixedly connected to the inside of the shell 1, a monitoring component 8 is fixedly connected to the inner bottom wall of the shell 1, a rotating component 9 is fixedly provided inside the shell 1, a nozzle 10 is fixedly connected to the inner top wall of the shell 1, and the upper outer wall of the nozzle 10 is fixedly connected to the inside of the water tank 6; a hole is opened inside the support plate 7.

[0024] Specifically, when preparing waterproof polyester fabric, the fabric is first placed in the outer shell 1, and the rotating component 9 is started to drive the fabric to move and spread it flat on the support plate 7. Then, the valve of the water tank 6 is opened, and the waterproofing solution in the water tank 6 is evenly sprayed on the surface of the fabric through the nozzle 10. Since there are holes inside the support plate 7, the waterproofing solution can penetrate smoothly. After the impregnation is completed, the conveying component 3 starts to work and transports the waterproof polyester fabric into it. Then the fan 4 is started, and the hot air blown out by the fan 4 dries and heats the fabric. Finally, the baked fabric is transferred to the discharge end by the conveying component 3 to complete the preparation of the waterproof polyester fabric. Through the close cooperation of various components, a complete and stable production process is formed from pretreatment to finished product output. The parameters of each link are precisely controlled, which reduces interference from human factors, ensures the consistency and stability of product quality, simplifies the production process, reduces the equipment footprint, and reduces the equipment connection cost and failure risk.

[0025] Please see the attached Figure 2 and attached Figure 3 The recovery component 5 includes a water pump 51, the outer wall of the water pump 51 is fixedly connected to the outer wall of the outer shell 1, the upper side of the water pump 51 is fixedly connected to a connecting pipe 1 52, the outer wall of the connecting pipe 1 52 is fixedly connected to the inside of the water tank 6, the lower side of the water pump 51 is fixedly connected to a connecting pipe 2 53, the outer wall of the connecting pipe 2 53 is fixedly connected to the inside of the outer shell 1, the lower side of the water pump 51 is fixedly connected to a connecting pipe 3 54, and the outer wall of the connecting pipe 3 54 is fixedly connected to the lower side of the conveying component 3.

[0026] Specifically, in the preparation process of waterproof polyester fabric, when the monitoring component 8 detects that the liquid in the shell 1 reaches a certain liquid level, the recovery component 5 is driven by the monitoring component 8 to start working, the water pump 51 is started, and the excess liquid in the shell 1 is extracted through the connecting pipe 2 53. At the same time, the liquid accumulated on the lower side of the conveying component 3 is also extracted through the connecting pipe 3 54. Afterwards, the water pump 51 conveys the extracted liquid back to the water tank 6 through the connecting pipe 1 52 to realize the recycling and reuse of the liquid. During the whole process, the water pump 51 continues to work until the liquid level in the shell 1 and the conveying component 3 returns to the normal range. The recovery component 5 can recycle the liquid in the shell 1 and the conveying component 3 to the water tank 6, realizing the recycling of resources such as waterproofing solution, which greatly reduces the waste of raw materials, reduces production costs, improves resource utilization efficiency, and makes the enterprise more economical and environmentally friendly in the production process.

[0027] Please see the attached Figure 3 and attached Figure 5 The monitoring component 8 includes a connecting frame 81, the lower surface of the connecting frame 81 is fixedly connected to the inner bottom wall of the outer shell 1, a water inlet 82 is opened inside the lower side of the connecting frame 81, a float 83 is provided inside the connecting frame 81, a liquid level sensor 84 is provided on the inner wall of the connecting frame 81, the outer wall of the liquid level sensor 84 is fixedly connected to the inner wall of the outer shell 1, the outer wall of the outer shell 1 is fixedly connected to the control center 85, and the liquid level sensor 84 and the control center 85 are electrically connected.

[0028] Specifically, during the preparation process of the waterproof polyester fabric, as the waterproofing agent is sprayed, liquid will gradually accumulate in the outer shell 1. The water inlet 82 inside the lower side of the connecting frame 81 allows the liquid in the outer shell 1 to flow into the interior of the connecting frame 81. When the liquid flows into the connecting frame 81, the float 83 inside it will rise as the liquid level rises. Once the float 83 contacts the liquid level sensor 84, the liquid level sensor 84 will be triggered. Since the liquid level sensor 84 is electrically connected to the control center 85 on the outer wall of the outer shell 1, the liquid level sensor 84 will transmit the signal to the control center 85 at this time. After receiving the signal, the control center 85 will issue an instruction to control the start of the water pump 51. The control center 85 is mainly used to trigger the start of the water pump 51 of the recovery component 5, thereby pumping the excess liquid in the shell 1 back to the water tank 6 for recycling. With the help of the electrical connection between the liquid level sensor 84 and the control center 85, the entire monitoring and recovery process is automated, and there is no need for manual attention to the liquid level at all times, which reduces the complexity and labor intensity of manual operation, and also avoids problems such as liquid overflow due to human negligence, thereby improving the automation level and stability of the production process.

[0029] Please see the attached Figure 4The rotating component 9 includes a motor 2 91, the outer wall of the motor 2 91 is fixedly connected to the left upper surface of the shell 1, the output end of the motor 2 91 is connected to a mounting rod 2 97, the outer wall of one end of the mounting rod 2 97 is fixedly connected to a gear 1 92, and the outer wall of the other end of the mounting rod 2 97 is fixedly connected to a gear 2 93; the rotating component 9 also includes a gear 4 96, the tooth end of the gear 4 96 is meshedly connected to the tooth end of the gear 1 92, the inner wall of the gear 4 96 is fixedly connected to a mounting rod 1 95, the outer wall of the mounting rod 1 95 is fixedly connected to a gear 3 94, and the tooth end of the gear 3 94 is meshedly connected to the tooth end of the gear 2 93; the gear 1 92 and the gear 4 96 are rotatably connected to the inside of the shell 1, and the gear 2 93 and the gear 3 94 are rotatably connected to the inside of the shell 1.

[0030] Specifically, the rotation of mounting rod 2 97 causes gears 1 92 and 2 93 fixed at its ends to rotate synchronously. When gear 1 92 rotates, gear 4 96, which meshes with its tooth end, also rotates. The rotation of gear 4 96 in turn drives mounting rod 1 95 fixed to its inner wall to rotate. As mounting rod 1 95 rotates, gear 3 94, fixed to its outer wall, also rotates. Gear 3 94 meshes with gear 2 93, further enhancing the stability and power transmission efficiency of the entire transmission system. Rotating assembly 9 can efficiently transmit the power of motor 2 91 to the fabric, achieving precise position control of the fabric and more stable movement of the fabric, ensuring that the fabric remains flat during the paving process and avoiding wrinkles or offsets. This provides a good foundation for subsequent waterproofing treatment and effectively improves product quality.

[0031] Please see the attached Figure 6 and attached Figure 7 The conveying component 3 includes a fixed shell 31, the outer wall of the fixed shell 31 is fixedly connected to the right outer wall of the outer shell 1, the outer wall of the fixed shell 31 is fixedly connected to the fixed shell 2 32, the inner wall of the fixed shell 2 32 is fixedly connected to the motor 1 33, the output end of the motor 1 33 is connected to the support column 1 34, the interior of the fixed shell 31 is fixedly connected to the fixed frame 35, the outer wall of the support column 1 34 is rotatably connected to the interior of the fixed frame 35, and the right side of the fixed frame 35 is rotatably connected to the support column 2 37, the outer wall of the support column 1 34 is provided with a conveyor belt 36, the right side of the conveyor belt 36 is provided on the outer wall of the support column 2 37, and the outer wall of the conveyor belt 36 is slidably connected to the interior of the fixed frame 35; the outer wall of the fixed frame 35 is fixedly connected to the heating plate 38, and the interior of the conveyor belt 36 is provided with a hole.

[0032] Specifically, when the entire preparation process is started, the output end of the motor 1 33 drives the support column 1 34 to rotate. Since the outer wall of the support column 1 34 is rotatably connected to the inside of the fixed frame 35, and a conveyor belt 36 is provided on its outer wall, and the right side of the conveyor belt 36 is sleeved on the outer wall of the support column 2 37, the rotation of the support column 1 34 will drive the conveyor belt 36 to circulate inside the fixed frame 35, and then start the fan 4 to dry the fabric with hot air. Since there are holes in the conveyor belt 36, this not only helps the hot air to penetrate the conveyor belt 36, accelerates the evaporation of moisture on the surface of the fabric, and improves the drying efficiency, but also makes the drying more uniform, avoiding the situation where the fabric is locally dry and wet unevenly.

[0033] The dried fabric continues to be transferred to the bottom of the heating plate 38 fixedly connected to the outer wall of the fixed frame 35 as the conveyor belt 36 rotates. The heating plate 38 starts to work, heating the fabric to 180°C and maintaining it for 120 seconds, prompting the waterproofing agent to cross-link with the fiber surface to form a film. Finally, the conveyor belt 36 transports the cross-linked and baked fabric to the discharge end, completing the fabric transportation work in the entire preparation process.

[0034] Please see the attached Figure 8 , a preparation process of a waterproof polyester fabric, comprising the following steps: S1. Fabric pretreatment: Place waterproof polyester fabric inside housing 1. Drive gear 1 92, gear 2 93, gear 3 94, and gear 4 96 to rotate via motor 2 91. Finally, mounting rod 2 97 and mounting rod 1 95 cooperate to drive the fabric to move, so that the fabric is laid flat on support plate 7. The porous structure of support plate 7 facilitates liquid penetration. S2, waterproofing agent impregnation, start the valve of the water tank 6, so that the waterproofing agent solution is evenly sprayed on the surface of the fabric through the nozzle 10. The concentration of the waterproofing agent solution is 40g / L and the pH value is 4.5-5 to ensure that the waterproofing agent fully penetrates into the fiber; S3, efficient drying, the impregnated fabric is transported to between the fixed shell 1 31 and the fixed shell 2 32 by the conveyor belt 36 of the conveying assembly 3, and the fan 4 is started to dry the fabric with hot air. The porous structure of the conveyor belt 36 accelerates the evaporation of water; S4, crosslinking and baking, the dried fabric is transferred to the lower surface of the heating plate 38 via the conveyor belt 36 for heating, and the fabric is baked at 180°C for 120 seconds to promote the crosslinking of the waterproofing agent with the fiber surface to form a film; S5, waste liquid recovery and monitoring. The monitoring component 8 monitors the liquid level in the housing 1 in real time through the float 83. When the float 83 touches the liquid level sensor 84, the control center 85 triggers the water pump 51 of the recovery component 5 to pump the waste liquid back to the water tank 6 through the connecting pipe 2 53 and the connecting pipe 3 54 for recycling, thereby saving water resources. S6: Finished product output. After baking is completed, the conveying component 3 moves the fabric to the discharge end, completing the preparation of the waterproof polyester fabric.

[0035] Specifically, when preparing waterproof polyester fabric, the fabric is first pretreated. The fabric is placed in housing 1 and motor 2 91 is started. The output shaft of motor 2 91 rotates mounting rod 2 97, which in turn rotates gears 1 92 and 2 93 on mounting rod 2 97. Gear 1 92 meshes with gear 4 96, driving gear 4 96 to rotate. Gear 4 96, through mounting rod 1 95, drives gear 3 94, which in turn meshes with gear 2 93. This series of gear transmissions enables mounting rods 2 97 and 1 95 to work in tandem, driving the fabric within housing 1 and laying it flat on support plate 7 with holes, preparing it for subsequent processing.

[0036] Then enter the waterproofing agent impregnation stage, open the water tank 6 valve, and the waterproofing agent solution with a concentration of 40g / L and a pH value of 4.5-5 is evenly sprinkled on the fabric surface through the nozzle 10. Due to the porous structure of the support plate 7, the waterproofing agent solution can smoothly penetrate into the interior of the fabric fibers, achieving waterproof treatment of the fabric.

[0037] After impregnation, the fabric is efficiently dried using conveyor assembly 3. Motor 1 33 drives support column 1 34 to rotate, driving conveyor belt 36 to move the impregnated fabric between fixed shell 1 31 and fixed shell 2 32. At this point, fan 4 is activated, and hot air passes through the holes in conveyor belt 36 to dry the fabric and accelerate water evaporation.

[0038] The dried fabric is then transferred by a conveyor belt 36 to a heating plate 38 for crosslinking and baking. The heating plate 38 heats the fabric to 180°C for 120 seconds, causing the waterproofing agent to crosslink with the fiber surface to form a waterproof film, thereby improving the fabric's waterproof properties.

[0039] During the entire process, the monitoring component 8 continues to work, and the liquid in the shell 1 flows in through the water inlet 82 of the connecting frame 81. When the liquid level rises, the float 83 rises accordingly and touches the liquid level sensor 84. The liquid level sensor 84 transmits a signal to the control center 85. After receiving the signal, the control center 85 triggers the water pump 51 of the recovery component 5 to start. The water pump 51 pumps the waste liquid in the shell 1 and the lower side of the conveying component 3 back to the water tank 6 through the connecting pipe 2 53 and the connecting pipe 3 54, thereby realizing waste liquid recovery and water resource recycling. Finally, the fabric that has been cross-linked and baked is transferred to the discharge end by the conveying component 3 to complete the preparation of the waterproof polyester fabric.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
