Under the action of the magnetic force, the driven shaft of the magnetic coupling 5 obtains an instantaneous speed, driving the air shaft 7 between the safety chuck 1 6 and the safety chuck 2 8 to rotate, thereby winding the fabric.

[0027] The present application is described below by means of a specific embodiment.

[0028] like Figure 1 As shown, the present application designs a split base, namely base one 4 and base two 9, base one 4 is connected to a safety chuck one 6, base two 9 is connected to a safety chuck two 8, the clamping axes of safety chuck one 6 and safety chuck two 8 coincide, so as to be able to clamp the pneumatic shaft 7, and the pneumatic shaft 7 is installed between safety chuck one 6 and safety chuck two 8.

[0029] The safety chuck 1 6 or the safety chuck 2 8 is connected to the driven shaft of the magnetic coupling 5, and the driving shaft of the magnetic coupling 5 is connected to the pneumatic motor 1 with a reducer. The pneumatic motor 1 with a reducer drives the air shaft 7 to rotate through the magnetic coupling 5 and the safety chuck to realize the winding of the fabric.

[0030] In some embodiments, a ratchet device is also connected to the driven shaft of the magnetic coupling 5, and the ratchet device can enable the inflatable shaft 7 to perform normal forward winding work and prevent the inflatable shaft 7 from rotating in the opposite direction.

[0031] The pneumatic motor 1 with a reducer is connected to an air source via a compressed air interface 2. Furthermore, an electromagnetic valve with an adjustable opening is provided between the compressed air interface 2 of the pneumatic motor 1 and the air source. By adjusting the opening of the electromagnetic valve, that is, controlling the flow rate of compressed air, the output power of the pneumatic motor 1 with a reducer is adjusted to achieve control of the winding force generated by the winding speed.

[0032] In a further embodiment, a slide rail 3 is provided on the base 4, and the arrangement direction of the slide rail 3 is the same as the axial direction of the air shaft 7 after installation; the pneumatic motor 1 with a reducer is connected to the slider of the slide rail 3 to achieve a sliding connection with the slide rail 3.

[0033] The air motor 1 with a reducer can be moved by the slide rail slider to adjust the spacing of the magnetic coupling 5, so that the magnetic flux changes, that is, the magnitude of the magnetic force changes, thereby achieving the purpose of adjusting the rotational torque of the air motor 1 with a reducer to drive the winding air shaft 7, and achieving constant tension winding of the three-dimensional fabric.

[0034] In a further embodiment, the pneumatic motor 1 with a reducer is further provided with a locking member for fixing the pneumatic motor 1 on the slide rail 3. The locking member can be a locking member or other types of locking members matched with a pin shaft and a shaft hole.

[0035] In some embodiments, the pneumatic motor 1 with a reducer can be displaced by a driving member, specifically, the driving member can be a cylinder, the output end of the cylinder is connected to the pneumatic motor 1 with a reducer, when the pneumatic motor 1 with a reducer needs to slide on the slide rail 3, it can be achieved by telescopic cylinder. The pneumatic motor 1 with a reducer is connected by the cylinder, and when the cylinder is not working, the pneumatic motor 1 with a reducer can be locked, and a separate locking member may not be designed at this time.

[0036] In some embodiments, the connection between the slide rail 3 and the base 4, and the connection between the base and the safety chuck can be connected by bolts.

[0037] In one embodiment, the bottom surfaces of the base 1 4 and the base 2 9 are provided with a clamping plate 10, and the clamping plate 10 is provided with a long bolt 11. The device can be fixed on the frame of the three-dimensional knitting machine through the clamping plate 10 and the long bolt 11. The clamping plate 10 and the base 1 4 and / or the base 2 9 are connected by bolts.

[0038] The present application adopts the form of a magnetic coupling. When the winding speed is set according to the process and quality requirements, the driven shaft of the magnetic coupling 5 will rotate. When the winding tension of the three-dimensional fabric is exceeded, the driven shaft will stop rotating until it is less than or equal to the set tension. The driven shaft will then rewind again and quickly accelerate the winding speed to synchronize the driven force with the fabric winding tension requirement, so that the winding speed is always maintained at the set value, ensuring the uniformity and stability of the winding speed.

[0039] The assembly steps of the winding device of the present application can be as follows:

[0040] Step 1: Determine the installation position of the clamping plate on the three-dimensional braiding machine, and fix the clamping plate 10 on the frame of the three-dimensional braiding machine by four long bolts 11.

[0041] Step 2: Determine the installation position of the base 4 and plan the line, and punch holes on the clamping plate 10 to reserve a position for the installation position of the base 4.

[0042] Step 3: Determine the installation position of the safety chuck 6 and plan the line, and punch a hole on the base to reserve a position for the installation position of the safety chuck 6.

[0043] Step 4: Determine the installation position of the slide rail 3 on the base 4, and mark and drill reserved holes.

[0044] Step 5: Fix the safety chuck 6 and base 4 to the right clamping plate 10 with screws according to the marked position.

[0045] Step 6: Fix the slide rail 3 on the base 4 with screws according to the marked position.

[0046] Step 7: As above, confirm that the second safety chuck 8 and the second base 9 are drilled at the installation position of the left clamping plate 10.

[0047] Step 8: Fix the safety chuck 2 8 and the base 2 9 on the left clamping plate 10 with screws according to the marked position.

[0048] Step 9: Install the magnetic coupling 5 on the safety chuck 6 to fix the safety chuck and the pneumatic motor 1 with a reducer.

[0049] Step 10: Install and fix the pneumatic motor 1 with a reducer on the magnetic coupling 5.

[0050] Step 11. Fix the bottom end of the pneumatic motor with reducer-1 on the slide rail slider 3 with screws.

[0051] Step 12: Connect the compressed air interface 2 to the head end of the pneumatic motor 1 with the reducer.

[0052] Step 13: Install and fix the inflatable shaft 7 between the safety chuck 1 6 and the safety chuck 2 8.

[0053] Step 14: Move the pneumatic motor 1 with the reducer, and adjust the winding tension through the spacing of the magnetic coupling 5.

[0054] The application collection process is as follows:

[0055] Step 1: The paper tube is placed on the air shaft 7, and the sleeve fabric is fixed on the paper tube in the winding direction.

[0056] Step 2, turn on the switch of compressed air, and the pneumatic motor 1 with a reducer starts to rotate. The rotation of the pneumatic motor 1 with a reducer drives the driving shaft of the magnetic coupling 5 to rotate to generate a magnetic field. Under the action of the magnetic force, the driven shaft of the coupling obtains an instantaneous speed, driving the air shaft to rotate to reel the sleeve fabric.

[0057] Step 3: By adjusting the opening of the air inlet valve, the flow of compressed air is controlled, and the output power of the pneumatic motor is adjusted to control the winding speed. At the same time, the distance between the magnetic couplings is adjusted by moving the pneumatic motor on the slide rail, so that the magnetic flux changes, that is, the magnitude of the magnetic force changes, thereby adjusting the torque of the winding shaft driven by the pneumatic motor, and achieving the goal of maintaining constant tension when the three-dimensional sleeve fabric changes speed;

[0058] Step 4: When the fabric reaches the set length, close the compressed air valve, stop the air shaft from rotating, loosen the safety chuck, and replace the paper tube.

[0059] In summary, this application has the following advantages:

[0060] 1. By adjusting the opening of the air inlet solenoid valve, that is, controlling the flow of compressed air, the output power of the pneumatic motor can be adjusted to achieve the winding force generated by controlling the winding speed. At the same time, the distance between the magnetic couplings is adjusted by moving the pneumatic motor on the slide rail to change the magnetic flux, that is, change the size of the magnetic force, thereby achieving the purpose of adjusting the torque of the winding shaft driven by the pneumatic motor, and achieving constant tension winding of three-dimensional fabrics.

[0061] 2. This application will not cause overload failure. When the winding speed is set according to the process and quality requirements, the driven shaft of the magnetic coupling will rotate, and when it exceeds the winding tension of the three-dimensional fabric, the driven shaft will stop rotating. Until it is less than or equal to the set tension, the driven shaft will rewind again, and quickly accelerate the winding speed to synchronize the driven force with the fabric winding tension requirement. During this variable period, since the active and passive transmissions transfer kinetic energy through the magnetic field, there is no rigid kinetic energy transfer between them. Therefore, the driven shaft of the pneumatic shaft can operate normally immediately, so that the winding speed is always maintained at the set value, ensuring the uniformity and stability of the winding speed, and at the same time, no faults such as machine damage will occur. It can operate continuously at full load for a long time without temperature rise failures.

[0062] 3. This application can use domestic pneumatic motors, which have great price advantages compared to imported pneumatic motors. It only needs to be used with a reducer to achieve a constant winding speed and uniform and stable winding tension. The pneumatic motor has a simple structure, is easier to repair and maintain, and has a long service life.

[0063] 4. After using the magnetic coupling in this application, the damage to the shaft caused by the concentricity problem of the equipment and the vibration mechanical energy damage can be reduced, thereby extending the service life of the pneumatic motor. At the same time, the magnetic coupling relies on the magnetic field to transmit torque, and is a truly contactless connection device. This connection device can make the rigidity damage of the active and passive shafts zero when the equipment transmits kinetic energy, greatly improving the service life of the shaft.

[0064] 5. This application uses a magnetic coupling, which can well realize flexible starting of the equipment and can well protect the pneumatic motor and load.

[0065] 6. This application is simple to operate, convenient and flexible. It can achieve high-efficiency and high-precision winding, can replace manual winding and rewinding, reduce labor costs, and achieve high-efficiency and high-precision winding.

[0066] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features.
