They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1
[0021] Please see Figures 1 to 6 This invention provides a technical solution: a cutting device and method for knitted fabric production. The cutting device for knitted fabric production includes: a frame 1 and an electric push rod 27. Fabric 25 is laid on the surface of the frame 1, and the fabric 25 is fixed to the surface of the frame 1 by clamps to keep it flat. The frame 1 is fixedly connected to a first motor 2 and a second motor 3. A cross-shaped protrusion is fixedly connected to the output end of the first motor 2, and the cross-shaped protrusion is inserted into one end of a first screw 4 to fix the screw 4. Simultaneously, the first motor 2 can drive the screw 4 to rotate. The other end of the screw 4 is rotatably connected to a plug through an interference fit bearing. The plug is inserted into the frame 1. The second motor 3... The output end is fixedly connected to a cross-shaped protrusion, which is inserted into the drive rod 9. At this time, the motor 2 3 can drive the drive rod 9 to rotate. The other end of the drive rod 9 is rotatably connected to a plug through an interference fit bearing. The plug is rotatably connected to the frame 1. The screw 1 4 passes through the slider 1 6 and is threadedly connected to it. When the screw 1 4 rotates, the slider 1 6 changes state. The surface of the slider 1 6 is rotatably connected to one end of the screw 2 5. The other end of the screw 2 5 passes through the slider 2 7 and the connecting plate 10 in sequence and is fixedly connected to the bevel gear 2 24. At this time, when the slider 1 6 slides, the slider 2 7 and the connecting plate 10 can slide synchronously along the screw 1 4. The connecting plate 10 is rotatably connected to the screw 2 5.
[0022] When motor 12 is started, screw 14 rotates, and slider 16 begins to move along screw 14 under the action of the screw thread. At this time, slider 27 and connecting plate 10 move synchronously.
[0023] The outer side of the connecting plate 10 is fixedly connected to one end of the guide rod 8. The other end of the guide rod 8 passes through the second slider 7 and is fixedly connected to the first slider 6. The second slider 7 can be supported by the guide rod 8 and the second screw 5. Guide holes 26 are provided at both ends of the connecting plate 10. The inner wall of the guide hole 26 is rotatably connected to the first bevel gear 23 through the interference fit of the bearing. The second slider 7 is slidably connected to the guide rod 8 and threadedly connected to the first screw 4. When the first screw 4 rotates, the second slider 7 begins to slide along the guide rod 8. The electric push rod 27 is fixedly connected at the midpoint of the second slider 7. The output end of the electric push rod 27 has a surface... The surface of the fixed plate 28 is threaded, and a sleeve 30 and a block 31 are fixedly connected to the surface of the fixed plate 28. The other end of the sleeve 30 is rotatably connected to the fixed cylinder 29 through a protrusion. The fixed cylinder 29 is threadedly connected to the output end of the electric push rod 27. The output end of the electric push rod 27 passes through the sleeve 30 and is inserted into its block 31. The block 31 limits the fixed plate 28 to prevent rotation. The sleeve 30 is fitted onto the surface of the output end of the electric push rod 27. The fixed plate 28 is fixedly connected to the servo motor 11. The electric push rod 27 can drive the servo motor 11 to move vertically up and down. The fixed plate 28 is fixedly connected to the servo motor 11.
[0024] When motor 23 starts, bevel gear 23 rotates, and bevel gear 24 drives screw 25 to rotate. At this time, slider 27 begins to slide along guide rod 8, and servo motor 11 moves with slider 27.
[0025] An output rod 12 is fixedly connected to the output end of the servo motor 11. A limiting plate 13 is fixedly connected to the surface of the output rod 12. The servo motor 11 can drive the output rod 12 to rotate. A fixing bolt 15 is threadedly connected to the inner wall of the output rod 12. A groove is opened at the end of the output rod 12 away from the servo motor 11. It is engaged with the cutting disc 16 through the groove. When the output rod 12 rotates, the cutting disc 16 rotates accordingly. One side of the cutting disc 16 contacts the limiting plate 13, and the other side is in close contact with the limiting plate 14. The other side of the limiting plate 14 is in close contact with the fixing bolt 15. The limiting plate 13 and the limiting plate 14 can fix the cutting disc 16 to prevent it from wobbling from side to side. A protective shell 20 is fixedly connected to the side of the servo motor 11. The protective shell 20 is hinged to the cover plate 21. A slot 22 is opened on the side of the protective shell 20. The protective shell 20 and the cover plate 21 can protect the cutting disc 16 and prevent it from contacting foreign objects.
[0026] Rotating the fixed cylinder 29 can move the fixed plate 28 upward, thereby allowing the output end of the electric push rod 27 to be inserted into the block 31, thus fixing the position of the fixed plate 28. When the cutting blade 16 rotates under the drive of the servo motor 11, it can cut the fabric 25. At the same time, the height can be changed by the electric push rod 27.
[0027] A connecting rod 18 is slidably connected to the surface of the cover plate 21. One end of the connecting rod 18 is fixedly connected to a locking plate 17, which can lock the cover plate 21. The other end of the connecting rod 18 is fixedly connected to a spring 19, and the other end of the spring 19 is fixedly connected to the cover plate 21. The spring 19 facilitates quick unlocking. The spring 19 is sleeved on the surface of the connecting rod 18, and the locking plate 17 is inserted into the slot 22. At this time, the cover plate 21 is in close contact with the protective shell 20, and most of the cutting blade 16 is inside the protective shell 20. Even if it breaks, it will not fly out, thus protecting the workers.
[0028] Example 2
[0029] This invention provides a technical solution: a method for cutting equipment used in the production of knitted fabrics. Insert the cutting disc 16 into the output rod 12, then attach the limiting disc 14, and thread the fixing bolt 15 to the output rod 12, so that both sides of the cutting disc 16 are in close contact with the limiting disc 13 and the limiting disc 14 respectively. At this time, the position of the cutting disc 16 is fixed and will not shake. Then rotate the cover plate 21 and slide the connecting rod 18. At this time, the spring 19 is compressed. When the cover plate 21 is in contact with the protective shell 20, the connecting rod 18 is released. At this time, the clamping plate 17 is inserted into the clamping slot 22. At the same time, under the action of the spring 19, the clamping plate 17 is not easy to disengage from the clamping slot 22. Lay the cloth 25 on the surface of the frame 1 and fix it. Then start the servo motor 11. At this time, the cutting disc 16 rotates, and the system program drives the motor 1 and the electric motor 2. When the second motor 3 rotates, the first motor 2 rotates, driving the first screw 4 to rotate. The movement of the second slider 7 can move the position of the cutting blade 16. At this time, the first slider 6 slides, driving the second slider 7 and the connecting plate 10 to slide. The connecting plate 10 slides along the drive rod 9. The second motor 3 starts, driving the drive rod 9 to rotate. The drive rod 9 drives the first bevel gear 23 to rotate, thereby driving the second bevel gear 24 to rotate. At this time, the second screw 5 rotates, and the second slider 7 slides along the guide rod 8. During the movement of the second slider 7, the electric push rod 27 can be activated. Through the coordinated activation of the electric push rod 27, the first motor 2, and the second motor 3, the cutting blade 16 can be moved to cut at any position. The cutting blade 16 moves vertically and contacts the fabric 25 to cut it.
[0030] The bevel gear 23 engages with the protruding part on the surface of the drive rod 9. When the drive rod 9 rotates, the bevel gear 23 starts to rotate. The drive rod 9 passes through the guide holes 26 at both ends of the connecting plate 10 and rotates to connect with them, thus ensuring the normal movement of the connecting plate 10 and the drive rod 9.
[0031] When this device is in operation, the cover plate 21 can be quickly locked and unlocked by sliding the connecting rod 18. Then, the cutting blade 16 can be quickly disassembled by rotating the fixing bolt 15. At the same time, the program is input into the control panel of the control frame 1. The frame 1 is electrically connected to motor 1 2, motor 2 3, electric push rod 27 and servo motor 11 to control the start state, thereby controlling the position of the cutting blade 16 to cut different positions of the fabric 25, thus facilitating the cutting of the fabric 25 into various shapes and irregular lines.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
