Description

Technical Field

[0002] Breathable fabrics, due to their excellent airflow, moisture wicking, and lightweight properties, are widely used in clothing, home textiles, medical protective equipment, sporting goods, and many other fields. In the early stages of breathable fabric processing, a cutting mechanism is required for material preparation.

[0003] In existing technologies, fabric cutting mechanisms mostly use vacuum adsorption or mechanical clamping to fix the fabric during cutting. However, breathable fabrics are loose and soft, and using vacuum adsorption or mechanical clamping can easily cause deformation and mechanical damage to the breathable fabric. Furthermore, during the cutting process, the friction between the cutter and the fabric fibers (such as polyester, nylon, and composite fibers) can easily generate static electricity. Under the action of static electricity, cutting debris can easily adhere to the fabric or cause the fabric to stick to the cutter, affecting the separation of the cutter and the fabric. Based on this, this application proposes a fabric cutting mechanism for breathable fabrics. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides an embodiment: Please refer to Figures 1-4A feeding mechanism for breathable fabrics includes a workbench 1, with a lifting plate 2 above the workbench 1. The lifting plate 2 is connected to the workbench 1 via a lifting structure. Under the action of the lifting structure, the distance between the lifting plate 2 and the workbench 1 can be changed. In embodiment 1, the lifting structure includes a hydraulic telescopic rod 3 connected to the workbench 1. The output shaft end of the hydraulic telescopic rod 3 is connected to a connecting rod, and the top of the connecting rod is connected to the lifting plate 2. The extension and retraction of the hydraulic telescopic rod 3 can change the height of the connecting rod. When the height of the connecting rod changes, the height of the lifting plate 2 changes accordingly.

[0017] The bottom of the lifting plate 2 is provided with an antistatic spray plate 4, and the bottom of the antistatic spray plate 4 is provided with a vision sensor 25. When this application is in use, the vision sensor 25 can collect the position of the breathable fabric placed on the workbench 1. Based on the data collected by the vision sensor 25, the controller can determine the range of the breathable fabric that needs to be destaticated.

[0018] The antistatic spray plate 4 has a hollow structure, and its inner cavity is equipped with several partition components. The partition components include a fixed mesh plate 24 fixedly connected to the inner cavity of the antistatic spray plate 4 and a movable mesh plate 23 movably connected to the inner cavity of the antistatic spray plate 4. The movable mesh plate 23 is connected to the inner cavity of the antistatic spray plate 4 through a fourth telescopic structure 22, and the meshes of the movable mesh plate 23 and the fixed mesh plate 24 are staggered. Spray nozzles 21 are evenly arranged at the bottom of the inner cavity of the antistatic spray plate 4. Through the setting of the partition components, when the fixed mesh plate 24 and the movable mesh plate 23 are in a tight fit, the fixed mesh plate 24 can block the movable mesh plate 23, and the movable mesh plate 23 can block the fixed mesh plate 24, so that the areas on both sides of the partition components are independent of each other, realizing the control of the effective air inlet area of ​​the antistatic spray plate 4, and thus enabling precise control of the spray area of ​​the antistatic spray plate 4. When the fixed mesh plate 24 and the movable mesh plate 23 are separated, the spaces on both sides of the separating component are connected.

[0019] An ion fan 7 is installed on the lifting plate 2. The outlet of the ion fan 7 is connected to the inlet of the antistatic spray plate 4 through a second ion air input pipe 8. An electric ball valve is installed at one end of the second ion air input pipe 8. When the ion fan 7 is working, it can input ion air containing a large number of positive and negative ions into the inner cavity of the antistatic spray plate 4 through the second ion air input pipe 8. The ion air in the inner cavity of the antistatic spray plate 4 can be sprayed onto the breathable fabric to be unloaded through the nozzle 21, removing static electricity from the breathable fabric before unloading. The distance between the nozzle 21 and the breathable fabric can be set according to requirements and is not limited here.

[0020] The anti-static spray plate 4 has a slot, within which a breathable fabric feeding assembly is installed. This assembly is connected to the lifting plate 2. The assembly includes a fixed frame 16 connected to the lifting plate 2, with a feeding knife 17 located in the center. The feeding knife 17 is connected to the fixed frame 16 via a first telescopic structure 5. Flat, fixed airbags 19 are located on both sides of the feeding knife 17, connected to the fixed frame 16 via a second telescopic structure 18. Under the action of the second telescopic structure 18, the height of the flat, fixed airbags 19 can be changed. In use, the flat, fixed airbags 19 can be used to flexibly press and fix the breathable fabric, ensuring its stable position during feeding and facilitating feeding. Furthermore, the lifting plate 2 is equipped with an air pump 6. The air outlet of the air pump 6 is connected to the air inlet of the flat fixed airbag 19 through the air inlet pipe 20. One end of the air inlet pipe 20 is equipped with an electric ball valve and an electric pressure relief valve, and the air outlet of the air inlet pipe 20 is equipped with a pressure sensor. With the air pump 6 in operation, the flat fixed airbag 19 can be inflated through the air inlet pipe 20. During the inflation process, the pressure sensor detects the inflation pressure of the flat fixed airbag 19. The controller can determine whether the flat fixed airbag 19 has been fully inflated based on the data collected by the pressure sensor. When the flat fixed airbag 19 is fully inflated, the electric ball valve is closed to stop inflation. During the stage when the flat fixed airbag 19 fixes the breathable fabric, the pressure sensor detects the stability of the pressure inside the flat fixed airbag 19 so as to replenish the air in time. A pressure sensor is installed at the bottom of the flat-shaped fixing airbag 19. The pressure sensor collects the pressure data of the flat-shaped fixing airbag 19 on the breathable fabric, so that the controller of this application can control the pressure of the airbag on the breathable fabric. The model and specifications of both the pressure sensor and the pressure sensor are set according to the requirements and are not limited here.

[0021] A safety gap is provided between the flat-shaped fixing airbag 19 and the cutting blade 17 to prevent interference between the cutting blade 17 and the flat-shaped fixing airbag 19 when the cutting blade 17 moves up and down. The safety gap can be set according to requirements and is not limited here. In use, when the two sides of the breathable fabric cutting position are fixed by the flat-shaped fixing airbag 19, the cutting blade 17 can move down under the action of the first telescopic structure 5 to cut the breathable fabric. After cutting, during the upward movement of the cutting blade 17, the nozzle 21 sprays ion wind to eliminate the static electricity generated during cutting, which facilitates the separation of the cutting blade 17 from the breathable fabric and cleans the debris adhering to the surface of the cutting blade 17. After the cutting blade 17 separates from the breathable fabric, the flat-shaped fixing airbag 19 separates from the breathable fabric under the action of the second telescopic structure 18.

[0022] A groove 12 adapted to the unloading knife 17 is provided at the corresponding position on the top of the workbench 1. A groove cleaning assembly is provided on the workbench 1. The groove cleaning assembly includes an air compressor 9 connected to the workbench 1, an air supply main pipe 10, and a sealing plate 14 provided at the bottom of the inner cavity of the groove 12. One end of the air supply main pipe 10 is connected to the air outlet of the air compressor 9 through a one-way valve. The other end of the air supply main pipe 10 is provided with a first ion air input pipe 11. An air supply branch pipe 13 is provided in the middle of the bottom of the groove 12. The air inlet of the air supply branch pipe 13 is connected to the air supply main pipe 10. A groove adapted to the sealing plate 14 is provided on one side of the bottom of the groove 12. The sealing plate 14 is connected to the workbench 1 through a third telescopic structure 15.

[0023] The air inlet of the first ion air input pipe 11 is connected to the air outlet of the ion fan 7. An electric ball valve is provided at one end of the first ion air input pipe 11 and one end of the second ion air input pipe 8.

[0024] With the setting of the groove cleaning component, the position of the sealing plate 14 can be changed under the action of the third telescopic structure 15. When the sealing plate 14 is located in the groove, the air supply branch pipe 13 is in a connected state with the groove 12. When the air compressor 9 is working, the air compressor 9 can blow compressed air into the groove 12 through the air supply main pipe 10 and the air supply branch pipe 13. The compressed air is used to blow the groove 12, thereby cleaning the cutting debris in the groove 12. After cleaning, the ion wind generated when the ion fan 7 is working can be blown into the groove 12 through the first ion wind input pipe 11, the air supply main pipe 10 and the air supply branch pipe 13, which can efficiently remove the cutting debris that is adsorbed by electrostatic adsorption in the groove 12 and improve the cleaning effect of the groove 12.

[0025] In Example 1, the first telescopic structure 5, the second telescopic structure 18, the third telescopic structure 15, and the fourth telescopic structure 22 are all electric telescopic poles. The model and specifications of each electric telescopic pole can be set according to requirements and are not limited here.

[0026] As can be seen from the above description, when this application is used, a flat fixing airbag 19 is used to flexibly fix the breathable fabric, which can achieve uniform pressure on the surface of the fabric, avoid local stress concentration, and the pressure of the flat fixing airbag 19 can be precisely controlled by the inflation volume, which can flexibly adjust the fixing strength according to the weight, thickness and elastic modulus of different breathable fabrics, thereby improving the adaptability of this application.

[0027] Ion wind is used to remove static electricity accumulated before cutting the breathable fabric, reducing the cutting risk. During the upward movement of the cutting blade 17 and the upward movement of the flat fixed airbag 19, ion wind is used to eliminate static electricity generated during the cutting process, preventing the adhesion of debris due to static electricity and ensuring the smooth separation of the breathable fabric cutting component from the breathable fabric.

[0028] It features a self-cleaning function with 12 blade grooves for easy use.

[0029] All electrical components involved in this application are existing technologies. Those skilled in the art can select appropriate models of electrical components according to their needs. No restrictions or elaborations are made here. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies are connected by wires. According to the actual situation, appropriate controllers are selected to meet control requirements. For specific connections and control sequences, please refer to the description below. The electrical connections between each electrical component are completed in the order of their operation. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0030] In summary: When using the feeding mechanism for breathable fabrics, the breathable fabric is placed on the workbench 1. The vision sensor 25 can collect the position of the breathable fabric on the workbench 1. Based on the data collected by the vision sensor 25, the controller can determine the range of static electricity removal required for the breathable fabric. The fourth telescopic structure 22, located outside the static electricity removal range, operates, driving the movable mesh plate 23 connected to it to move until the movable mesh plate 23 and the fixed mesh plate 24 are in a tight fit, so that the inner cavity of the static electricity removal spray plate 4 can be precisely controlled according to the static electricity removal range. The first lifting structure drives the lifting plate to move down until the distance between the nozzle 21 and the breathable fabric reaches the set distance. The ion fan 7 operates, and the operation of the ion fan 7 causes ion air to be input into the inner cavity of the static electricity removal spray plate 4 through the second ion air input pipe 8. The ion air in the inner cavity of the static electricity removal spray plate 4 is sprayed onto the breathable fabric through the nozzle 21, removing the static electricity accumulated on the breathable fabric. After the breathable fabric is destaticated, the ion fan 7 stops working. The second telescopic structure 18 moves the flat fixing airbag 19 downward until the pressure between the flat fixing airbag 19 and the breathable fabric reaches a preset value. The breathable fabric is fixed by the flat fixing airbag 19. The first telescopic structure 5 moves the cutting blade 17 to cut the breathable fabric. After the breathable fabric is cut, the ion fan 7 works, and the first telescopic structure 5 moves the cutting blade 17 upward. During the upward movement of the cutting blade 17, the ion wind eliminates the static electricity generated during the cutting process and cleans the debris adhering to the surface of the cutting blade 17. After the cutting blade 17 separates from the breathable fabric, the second telescopic structure 18 moves the flat fixing airbag 19 upward and uses the ion wind to eliminate the static electricity accumulated on the flat fixing airbag 19 until the flat fixing airbag 19 separates from the breathable fabric. The first lifting structure moves the lifting plate 2 back to its original position, completing the breathable fabric cutting operation.
