[0030] A first mounting plate 101, on which a sliding groove clamping structure is arranged along the X-axis direction for sliding connection with an external substrate;

[0031] The second mounting plate 102 is mounted on the first mounting plate 101 through a distance adjustment mechanism arranged along the Y-axis direction, and the distance between the second mounting plate 102 and the first mounting plate 101 can be adjusted along the Y-axis direction through the distance adjustment mechanism;

[0032] The ultrasonic transducer 103 is rotatably mounted on the second mounting plate 102, the rotation axis direction of the ultrasonic transducer 103 is parallel to the Y axis, and an ultrasonic cutting knife 104 is provided at one end of the second mounting plate 102 away from the first mounting plate 101;

[0033] The rotation limiting mechanism is arranged at one end of the ultrasonic transducer 103 away from the ultrasonic cutting blade 104, and is used to lock the ultrasonic transducer 103 to prevent it from rotating.

[0034] The non-woven fabric ultrasonic cutting device according to the embodiment of the present invention has at least the following technical effects: the non-woven fabric ultrasonic cutting device of the present solution can realize the movement of the ultrasonic cutting knife 104 in the X-axis direction and the Y-axis direction, and can also make the ultrasonic cutting knife 104 rotate flexibly, which can be suitable for various cutting needs, and the present solution is also provided with a rotation limit device for controlling the ultrasonic transducer 103 to stop rotating, which can ensure the stability of the ultrasonic cutting knife 104 during cutting.

The telescopic direction of the linear cylinder 105 is parallel to the Y-axis direction, and the telescopic movement of the linear cylinder 105 can change the distance between the first mounting plate 101 and the second mounting plate 102, thereby realizing the adjustment of the position of the ultrasonic transducer 103 and the ultrasonic cutting knife 104 in the Y-axis direction.

Since the extension distance of the linear cylinder 105 cannot be adjusted, the amount of extension each time is fixed, and the first screw 106 in this embodiment can adjust the extension distance of the linear cylinder 105. When it is necessary to control the extension distance of the linear cylinder 105 to be less than the maximum extension distance of the linear cylinder 105, the first screw 106 is rotated so that the first screw 106 can move relative to the second mounting plate 102 to which it is threadedly connected, and under the action of the clamping joint 108, the first mounting plate 101 will move in the direction close to the second mounting plate 102, thereby shortening the distance between the first mounting plate 101 and the second mounting plate 102.

Figure 2 When the wedge block 112 rotates to abut against the external substrate, the locking mechanism 113 can lock the wedge block 112 to prevent it from continuing to rotate, so that the wedge block 112 is firmly abutted against the external substrate, thereby fixing the position of the non-woven fabric ultrasonic cutting equipment in the X-axis direction.

[0041] In some embodiments of the present invention, two guide rods 114 are provided between the first mounting plate 101 and the second mounting plate 102, one end of the guide rod 114 is fixed on the first mounting plate 101, and the other end is passed through the second mounting plate 102, the axial direction of the guide rod 114 is parallel to the Y axis, and the two guide rods 114 are symmetrically arranged on both sides of the ultrasonic transducer 103. The arrangement of the guide rods 114 makes the ultrasonic transducer 103 and the ultrasonic cutting knife 104 more stable when adjusted in the Y axis direction.

[0042] In some embodiments of the present invention, both guide rods 114 extend in the Y-axis direction to an end of the ultrasonic transducer 103 other than the end away from the ultrasonic cutting blade 104; a third mounting plate 115 is mounted on one end of the two guide rods 114 away from the ultrasonic cutting blade 104, and the rotation limiting mechanism includes a second screw rod 116 threadedly penetrated on the third mounting plate 115, and the second screw rod 116 can abut against the ultrasonic transducer 103 or be separated from the ultrasonic transducer 103 through thread adjustment.

The first protective cover 117 protects the ultrasonic transducer 103 and also prevents the operator from directly contacting the ultrasonic transducer 103, thereby ensuring the safety of the operator. In this embodiment, a plurality of evenly distributed heat dissipation holes are provided on the first protective cover 117 to ensure a good heat dissipation effect.

[0044] In some embodiments of the present invention, the non-woven fabric ultrasonic cutting device includes a second protective cover 118, which is arranged on a side of the second mounting plate 102 away from the external substrate, and a heat dissipation fan 119 and a plurality of heat dissipation holes are provided on the second protective cover 118.

[0045] Reference below Figure 1 and Figure 2 The nonwoven fabric ultrasonic cutting device according to the embodiment of the present invention is described in detail with a specific embodiment. It is worth noting that the following description is only an exemplary description and is not a specific limitation of the invention.

[0046] like Figure 1 and Figure 2As shown, the non-woven fabric ultrasonic cutting equipment is provided with a first mounting plate 101, and two mounting blocks 109 are provided on one side of the first mounting plate 101. The two mounting blocks 109 are arranged in parallel and at intervals, and each mounting block 109 is provided with a dovetail groove 110 extending along the X-axis direction. The dovetail groove 110 on the mounting block 109 is correspondingly arranged, and the first mounting plate 101 slides the non-woven fabric ultrasonic cutting equipment on the external substrate through the dovetail groove 110. Each mounting block 109 is provided with a slot 111 on a side wall of the dovetail groove 110, and a wedge block 112 is rotatably arranged in the slot 111, and the rotating axis of the wedge block 112 is parallel to the X-axis.

The locking mechanism 113 is used to limit the rotation of the wedge block 112 in the direction of exiting the dovetail groove 110. When the wedge block 112 rotates to abut against the external substrate, the locking mechanism 113 can lock the wedge block 112 to prevent it from continuing to rotate, so that the wedge block 112 is firmly abutted against the external substrate, thereby realizing the position fixation of the non-woven fabric ultrasonic cutting equipment in the X-axis direction. A second mounting plate 102 is disposed below the first mounting plate 101, and the second mounting plate 102 is parallel to the first mounting plate 101. A linear cylinder 105 is disposed on the first mounting plate 101, and the telescopic end of the linear cylinder 105 is connected to the second mounting plate 102. The telescopic direction of the linear cylinder 105 is parallel to the Y-axis direction. The telescopic movement of the linear cylinder 105 can change the distance between the first mounting plate 101 and the second mounting plate 102. In this embodiment, the ultrasonic transducer 103 is rotatably mounted on the second mounting plate 102, and the rotation axis direction of the ultrasonic transducer 103 is parallel to the Y-axis. An ultrasonic cutter 104 is disposed at one end of the second mounting plate 102 away from the first mounting plate 101. The telescopic movement of the linear cylinder 105 can adjust the positions of the ultrasonic transducer 103 and the ultrasonic cutter 104 in the Y-axis direction. Since the extension distance of the linear cylinder 105 cannot be adjusted and the extension amount each time is fixed, the first screw rod is threadedly provided on the second mounting plate in this embodiment, and the first screw rod is arranged along the Y-axis direction. One end of the first screw rod 106 passes through the first mounting plate 101 and is provided with a clamping joint 108.

Under the action of the clamping joint 108, the first mounting plate 101 will move in the direction close to the second mounting plate 102, thereby shortening the distance between the first mounting plate 101 and the second mounting plate 102. The setting of the first screw rod 106 plays the role of mechanical limit, which can limit the maximum extension distance of the linear cylinder 105, so that the position of the ultrasonic cutting knife 104 in the Y-axis direction can be precisely controlled by humans.Two guide rods 114 are provided between the first mounting plate 101 and the second mounting plate 102, one end of the guide rod 114 is fixed on the first mounting plate 101, and the other end is passed through the second mounting plate 102, the axial direction of the guide rod 114 is parallel to the Y axis, and the two guide rods 114 are symmetrically arranged on both sides of the ultrasonic transducer 103. The arrangement of the guide rods 114 makes the ultrasonic transducer 103 and the ultrasonic cutting knife 104 more stable when adjusted in the Y axis direction. Specifically, the two guide rods 114 extend in the Y-axis direction to the end of the ultrasonic transducer 103 away from the ultrasonic cutting knife; a third mounting plate 115 is mounted on one end of the two guide rods 114 away from the ultrasonic cutting knife 104, and a second screw 116 is passed through the third mounting plate 115 of the rotation limiter. The second screw 116 can abut against the ultrasonic transducer 103 or separate from the ultrasonic transducer 103. When the second screw 116 rotates to abut against the end face of the ultrasonic transducer 103, the ultrasonic transducer 103 can be affected by an external force and stop rotating; when the second screw 116 rotates to separate from the ultrasonic transducer 103, the ultrasonic transducer 103 and the ultrasonic cutting knife 104 can continue to rotate.
