[0032] Reference Figure 1-3 In this embodiment, guide grooves 101 are symmetrically fixedly installed above the support frame 1 and corresponding to the storage shell 2, and the number of guide grooves 101 is two pairs, and the guide grooves 101 are arranged in a C shape, and conveying rollers 1011 are equidistantly connected to the upper and lower sides of the guide grooves 101, and adjacent conveying rollers 1011 are connected by chain transmission, and a sprocket engaged with the chain is nested outside the conveying rollers 1011, and a motor A1012 is symmetrically installed on one side of the guide groove 101, and the output shaft of the motor A1012 is connected to the corresponding conveying roller 1011;

[0033] The starting end of the non-woven fabric is fed into the guide groove 101, and the motor A1012 drives the conveying roller 1011 to rotate, clamping the non-woven fabric and moving it slowly, thereby achieving the purpose of continuous cutting of the non-woven fabric.

[0034] Reference Figure 1 , 3 In this embodiment, a material receiving trough 103 is embedded on one side of the support frame 1. The four corners of the material receiving trough 103 are rotatably connected with a screw rod 1031 through a servo motor A1032. The screw rod 1031 is threadedly connected with a support plate 1033 on the outside. The support plate 1033 is L-shaped. A material receiving plate 1034 is slidably connected to the support plate 1033 through a slide rail. A limit plate 1035 is installed above the support plate 1033 through an electric cylinder 1036.

[0035] When the non-woven fabric is cut into equal-length non-woven fabric blocks, the servo motor A1032 drives the screw rod 1031 to rotate, driving the support plate 1033 and the receiving plate 1034 to move slowly upward, so that the receiving plate 1034 moves up to the exit of the guide groove 101, and according to the length of the non-woven fabric block, the electric cylinder 1036 is extended and retracted to adjust the purpose of the limit plate 1035, thereby adjusting the exposed length of the receiving plate 1034, and the non-woven fabric block moved out of the guide groove 101 falls on the receiving plate 1034. The servo motor A1032 drives the screw rod 1031 to rotate in the opposite direction, so that the support plate 1033 and the receiving plate 1034 move slowly downward, so that the non-woven fabric blocks are stacked in sequence on the receiving plate 1034, thereby achieving the purpose of collecting the non-woven fabric blocks.

[0036] Reference Figure 1 , 3 , 6, 7, in this embodiment, a winding frame 1022 is installed below the horizontal frame 102 through a servo electric cylinder 1021, one side of the winding frame 1022 is rotatably connected to a connecting rod 1024 through a motor B1023, and the other end of the connecting rod 1024 is threadedly connected to a winding roller 1025, an L-shaped connecting rod 104 is fixedly installed on one side below the horizontal frame 102, and one end of the L-shaped connecting rod 104 is threadedly connected to a limiting rod 1041, and a fixed block 105 is fixedly installed near the L-shaped connecting rod 104 on the other side of the support frame 1, and a through groove is provided in the middle of the fixed block 105, and a sawtooth bar 1051 is fixedly installed near the through groove below the fixed block 105;

[0037] The tape roll is put on the outside of the L-shaped connecting rod 104, and then the limiting rod 1041 is screwed on one end of the L-shaped connecting rod 104 to limit the tape roll, and the starting end of the tape roll passes through the through groove in the middle of the fixed block 105. When the non-woven fabric is cut, the servo electric cylinder 1021 extends and pushes the reel 1022 to move down, so that the reel 1025 is close to the exit of the guide groove 101. The staff pulls the starting end of the tape roll from under the fixed block 105. After pulling out a sufficient length, the tape is pulled to one side of the sawtooth bar 1051. The sawtooth bar 1051 cuts the tape, and the starting end of the non-woven fabric is fixed to the reel 1025 through the cut tape. The motor B1023 drives the connecting rod 1024 and the reel 1025 to rotate slowly, and the non-woven fabric that has been continuously cut is rolled up and unloaded.

[0038] Reference Figure 1 , 2 , 3, 6. In this embodiment, the solenoid valve A2044 and the solenoid valve B2054 are electrically connected to the external power supply through the electric slip ring, and the motor A1012, the servo cylinder 1021, the motor B1023, the servo motor A1032, the electric cylinder 1036, the micro air pump 2021, the servo motor B2031 and the electric slip ring are electrically connected to the external power supply through the switch panel.

[0039] Working principle: First, the printing machine prints the non-woven fabric, and the staff assists in feeding the starting end of the printed non-woven fabric into the guide groove 101. The motor A1012 drives the conveying roller 1011 to rotate, clamping the non-woven fabric and moving slowly. Then the servo motor B2031 drives the connecting cylinder 203 to rotate slowly. When the non-woven fabric needs to be cut, the electric slip ring of the control solenoid valve B2054 is turned on, and the solenoid valve B2054 is in an open state. When the connecting groove B205 rotates to the bottom, the opening B of the connecting groove B205 corresponds to the air outlet 2022. The micro air pump 2021 fills the connecting groove B205 with gas from the air outlet 2022. The air pressure pushes the connecting plate B2051 downward, and then pushes the cutting knife B2052 downward. The cutting knife B2052 impacts the surface of the non-woven fabric, leaving a continuous small hole on the surface of the non-woven fabric, forming an easy-to-tear line. When the cutting knife B2052 contacts the non-woven fabric, the connecting plate B2051 moves to the air outlet B2053 to discharge the internal gas of the connecting groove B205. The connecting plate B2051 rebounds and resets under the tension of the tension spring, and so on. The six connecting grooves B205 work continuously and alternately, continuously cutting equidistant easy-to-tear lines on the surface of the non-woven fabric. When the non-woven fabric is cut off when needed, the electric slip ring controlling the solenoid valve A2044 is turned on, and the solenoid valve A2044 is in an open state. When the connecting groove A204 rotates to the bottom, the opening A corresponding to the connecting groove A204 corresponds to the air outlet 2022, and the micro air pump 2021 is discharged from the air outlet. Gas is filled into the connecting groove A204 at 2022, and the air pressure pushes the connecting plate A2041 downward, thereby pushing the cutting knife A2042 downward to cut off the non-woven fabric. When the cutting knife A2042 contacts the non-woven fabric, the connecting plate A2041 just moves to the air outlet A2043, and the gas inside the connecting groove A204 is discharged from the air outlet A2043. The connecting plate A2041 is reset under the tension of the tension spring, and so on. The six connecting grooves A204 work alternately and continuously to cut off the non-woven fabric into equal-length non-woven fabric blocks. Then, when the non-woven fabric is cut into equal-length non-woven fabric blocks, the servo motor A1032 drives the screw rod 1031 to rotate, drives the support plate 1033 and the receiving plate 1034 to move up slowly, so that the receiving plate 1034 moves up. When it is close to the exit of the guide groove 101, the electric cylinder 1036 is extended and retracted according to the length of the non-woven fabric block to adjust the purpose of the limit plate 1035, and then the exposed length of the receiving plate 1034 is adjusted, and the non-woven fabric block removed from the guide groove 101 falls on the receiving plate 1034, and the servo motor A1032 drives the screw rod 1031 to rotate in the opposite direction, so that the support plate 1033 and the receiving plate 1034 slowly move downward, so that the non-woven fabric blocks are stacked on the receiving plate 1034 in sequence, so as to achieve the purpose of collecting the non-woven fabric blocks. When the non-woven fabric is point-cut, the servo electric cylinder 1021 extends and pushes the winding frame 1022 to move downward, so that the winding roller 1025 is close to the exit of the guide groove 101. The staff pulls the starting end of the tape roll from under the fixed block 105. After pulling out a sufficient length,Pull the tape toward the sawtooth bar 1051, the sawtooth bar 1051 cuts the tape, and the starting end of the non-woven fabric is fixed to the reel 1025 through the cut tape. The motor B1023 drives the connecting rod 1024 and the reel 1025 to rotate slowly, and the non-woven fabric that has been continuously cut is rolled up and unloaded. Finally, the staff can check whether the cutting knife A2042 and the cutting knife B2052 are damaged or deformed from the transparent visual window 201. When the cutting knife A2042 and the cutting knife B2052 are deformed, the staff opens the baffle at the inspection port and disassembles and replaces the cutting knife A2042 and the cutting knife B2052 from the inspection port.
