[0002] Currently, flexible sheet products (such as wovens, non-woven fabrics, paper, leather, synthetic materials, composite materials, etc.) require a large amount of cutting during the production process. Cutting machines are usually used to cut sheet products into specified shapes. The cutting blade is a slender blade with a sharp cutting edge. The cutting edge advances through the sheet along the specified cutting line while the blade reciprocates in a direction roughly perpendicular to the material.

[0031] Please also refer to Figures 1 to 6 , the ultrasonic cutting device provided by the embodiment of the present utility model is now described.

[0032] The ultrasonic cutting device includes a first direction X; the first direction X is the axial direction of the ultrasonic cutting device movement, such as Figure 1 As shown;

[0033] like Figures 1 to 3 As shown, the ultrasonic cutting device of an embodiment of the present invention includes: a housing 100, a cutting mechanism 200, a counterweight 300, and a driving mechanism 400; the driving mechanism 400 is used to drive the cutting mechanism 200 to reciprocate along a first direction; the cutting mechanism 200 includes a transducer 210, a horn 220, and a blade 230 connected in sequence along the first direction; a slide rail 110 is provided in the housing 100, and the counterweight 300 is located in the housing 100 and is slidably connected to the slide rail 110, and the sliding direction of the counterweight 300 is parallel to the first direction;

[0034] Reference Figures 1 to 3 The driving mechanism 400 includes a transmission part 440 and a power assembly 430 connected to each other; the transmission part 440 has a first output end 410 and a second output end 420; the first output end 410 is connected to the cutting mechanism 200; the second output end 420 is connected to the counterweight 300; the power assembly 430 drives the cutting mechanism 200 and the counterweight 300 to reciprocate along the first direction through the transmission part 440, and the moving direction of the counterweight 300 is opposite to the moving direction of the cutting mechanism 200;

[0035] Reference Figures 4 to 6 , wherein the transducer 210 and the transmission part 440 are arranged in the housing 100, the slide rail 110 is provided with a first limiting groove 111 extending along the first direction, and the counterweight block 300 is provided with a limiting member 310 extending into the first limiting groove 111, and the limiting member 310 is used to cooperate with the first limiting groove 111 to limit the stroke of the counterweight block 300.

[0036] The ultrasonic transmitter is electrically connected to the transducer 210 so as to transmit electrical energy to the transducer 210, so that the transducer 210 transmits high-frequency vibration to the blade 230 of the amplitude transformer 220, so that the blade 230 can vibrate ultrasonically at a high frequency axial direction; the blade 230 adds ultrasonic high-frequency axial vibration on the basis of the original low-frequency axial reciprocating motion to improve the cutting speed and cutting ability of the blade 230.

[0037] The counterweight 300 is slidably connected to the housing 100 via the slide rail 110, allowing the counterweight 300 to reciprocate in a first direction. Furthermore, the counterweight 300 simultaneously moves in the opposite direction to the cutting mechanism 200. The counterweight's neutral weight and reverse motion can also balance the inertial jitter generated by the cutting machine during its reciprocating motion after the ultrasonic component is added, thereby enabling the ultrasonic cutting device to achieve anti-shake, allowing the blade 230 to cut the object more smoothly. The closer the sum of the weights of the counterweight 300 and the second output terminal 420 is to the sum of the weights of the cutting mechanism 200 and the first output terminal 410, the better the corresponding anti-shake effect, thereby reducing tool jitter and achieving more precise cutting.

[0038] The slide rail 110 is provided with a first limiting groove 111, and the limiting member 310 of the counterweight 300 is stuck in the first limiting groove 111. Therefore, when the counterweight 300 moves, the limiting member 310 also moves together, and the cooperation between the limiting member 310 and the first limiting groove 111 can be used to limit the stroke of the counterweight 300. The maximum stroke of the limiting member 310 in the first limiting groove 111 along the first direction is the maximum stroke of the counterweight 300 in the first direction, that is, the first limiting groove 111 is used to limit the stroke of the counterweight 300, preventing the counterweight 300 from exceeding a preset moving distance during the reciprocating movement, preventing the counterweight 300 from being unable to reset due to the counterweight 300 moving too long and preventing the device from getting stuck. This makes the sliding of the counterweight 300 smoother and more stable, ensuring the normal use of the device.

[0039] It should be noted that the first output end 410 and the second output end 420 are both crank rocker mechanisms, and the power component 430 can be a drive motor or a pneumatic drive source. The drive motor is used to drive the crank of the crank rocker mechanism to rotate, so as to drive the cutting mechanism 200 and the counterweight block 300 to reciprocate in the first direction X, respectively, to ensure the normal operation of the equipment.

[0040] In some embodiments of the present invention, referring to Figures 4 to 6 The counterweight 300 is provided with a slide groove 320, the slide groove 320 is slidably connected to the slide rail 110, and the limiter 310 is arranged in the slide groove 320. The shape of the slide groove 320 is adapted to the shape of the slide rail 110, as shown in FIG. Figures 4 to 6 As shown, the slide rail 110 is square in shape, and the corresponding slide groove 320 is also square, so that the slide rail 110 can support the weight of the counterweight 300 and allow the counterweight 300 to slide more smoothly.

[0041] In some embodiments of the present invention, referring to Figures 4 to 6The ultrasonic cutting device further includes a limit block 600; a first limit groove 111 passes through the slide rail 110; one end of the limit member 310 is connected to the counterweight 300, and the other end of the limit member 310 is connected to the limit block 600; the slide rail 110 is provided with two limit bosses 112 on the side facing the limit member 310; a second limit groove 113 is formed between the two limit bosses 112; the limit block 600 is used to cooperate with the second limit groove 113 to limit the stroke of the counterweight 300. The limit block 600 is fixedly connected to the counterweight 300 through the limit member 310, that is, the limit block 600, the limit member 310, and the counterweight 300 have the same stroke in the first direction. Therefore, the two limit bosses 112 are used to limit the stroke of the limit block 600, thereby limiting the stroke of the counterweight 300. The travel of the counterweight block 300 is controlled by the first limit slot 111 and the second limit slot 113 to ensure that the moving distance of the counterweight block 300 is not too long, that the counterweight block 300 can move back and forth normally, that the counterweight block 300 can be reset normally, and that the equipment operates normally.

[0042] In some embodiments of the present invention, referring to Figures 4 to 6 The slide rail 110 is provided with a first sliding surface 114 and a second sliding surface 115 on opposite sides thereof. The first sliding surface 114 is in contact with the slide groove 320, while the second sliding surface 115 is in contact with the stop block 600. Specifically, the stop block 600 covers the slide groove 320, forming a sliding hole that can be fitted onto the slide rail 110. This allows the counterweight 300 to better fit with the slide rail 110, reduces the gap between the slide rail 110 and the counterweight 300, and reduces vibration of the counterweight 300 during sliding, ensuring smoother sliding of the counterweight 300.

[0043] In some embodiments of the present invention, referring to Figures 4 to 6 The first sliding surface 114 is provided with a first oil guide groove 116, and the second sliding surface 115 is provided with a second oil guide groove 117. Lubricating oil is contained in both the first oil guide groove 116 and the second oil guide groove 117 to reduce friction between the slide rail 110 and the slide groove 320, and between the slide rail 110 and the limit block 600, making the sliding of the counterweight 300 smoother and more stable.

[0044] In some embodiments of the present invention, referring to Figures 4 to 6 The first oil guide groove 116 and the second oil guide groove 117 are both wavy in shape. The wavy first oil guide groove 116 and the second oil guide groove 117 can increase the contact area between the lubricating oil and the slide rail 110, the counterweight 300, and the limit block 600, thereby better providing lubrication for the reciprocating movement of the counterweight 300 and ensuring smooth movement of the counterweight 300.

[0045] In some embodiments of the present invention, referring to Figures 4 to 6The limiting boss 112 is provided with a first mounting hole 118 that passes through the slide rail 110. The limiting boss 112 is connected to the housing 100 via a first connector 700 that passes through the first mounting hole 118. That is, the limiting boss 112 is affixed to the housing 100, and the first connector 700 is used to fix the slide rail 110 to the housing 100. The two limiting bosses 112 are located at both ends of the slide rail 110 to secure the entire slide rail 110 and reduce vibration of the slide rail 110. It should be noted that the first connector 700 may be a fastener such as a screw, bolt, or pin.

[0046] In some embodiments of the present invention, referring to Figures 4 to 6 The first limiting groove 111 is a strip hole, the length direction of the strip hole is parallel to the first direction, and the length of the strip hole is adapted to the preset stroke of the counterweight block 300 so that the counterweight block 300 moves according to the preset stroke; the limiting member 310 is a screw, which can connect the limiting block 600 to the counterweight block 300 for easy installation.

[0047] In some embodiments of the present invention, referring to Figures 4 to 6 The counterweight 300 is provided with an avoidance groove 330, the lower side of which has an opening, and the transducer 210 is located in the avoidance groove 330; there are two slide rails 110, two slide rails 110 are located below the counterweight 300, and the two slide rails 110 are respectively located on both sides of the opening of the counterweight 300. The avoidance groove 330 can accommodate the transducer 210 or the first output terminal 410. When installed, the counterweight 300 can cover the transducer 210 from top to bottom, so that the counterweight 300 can be set around the transducer 210, and ensure that the transducer 210 and the counterweight 300 do not touch each other during movement, thereby avoiding movement jams. The slide rail 110 is set below the counterweight 300, and the slide rail 110 can be used to support the entire counterweight 300, making the sliding more stable and smooth. It should be noted that the opening on the lower side of the avoidance groove 330 is an opening on the side of the avoidance groove 330 facing the peripheral side of the housing 100, that is, the lower side is the opening of the present application. Figure 4 、 Figure 5 The downward side of the counterweight block 300 shown in the figure does not limit the direction of the opening of the avoidance groove 330. Therefore, in other embodiments, the lower opening of the avoidance groove 330 can be replaced by an upper opening, a left opening or a right opening.

[0048] In some embodiments of the present invention, referring to Figures 4 to 6The counterweight 300 is provided with a second mounting hole 340 on the inner sidewall of the avoidance groove 330, and the second output end 420 of the transmission part 440 is provided with a third mounting hole 422. The second output end 420 is connected to the counterweight 300 via a second connecting member 800 that passes through the third mounting hole 422 and the second mounting hole 340. The counterweight 300 is further provided with an assembly hole 350 at a position corresponding to the third mounting hole 422. The second connecting member 800 is a fastener such as a screw, bolt, or pin to connect the second output end 420 to the counterweight 300, facilitating the power assembly 430 to drive the counterweight 300 to move back and forth in the first direction via the second output end 420. The assembly hole 350 of the counterweight 300 allows the installer to insert the second connecting member 800 through the assembly hole 350 into the second mounting hole 340 and the third mounting hole 422, so that the installer can use an installation tool to connect the second transmission rod 421 to the counterweight 300.

[0049] This embodiment also provides a machine tool, which includes: a drive device, a mounting column and an ultrasonic cutting device as described above, wherein the ultrasonic cutting device is arranged on the mounting column, and the drive device is used to drive the ultrasonic cutting device to generate vibration for cutting and move along a predetermined path. The drive device can be a linear drive module or a multi-axis drive module to drive the ultrasonic cutting device to move linearly or in space, and the drive device can also be connected to a transducer 210 to enable the cutting mechanism 200 to perform ultrasonic high-frequency vibration to improve the cutting ability of the cutting mechanism. The machine tool can directly apply the above-mentioned ultrasonic cutting device. Since a first limiting groove 111 is provided on the slide rail 110, when the counterweight 300 moves, the limiting member 310 also moves together, and the cooperation between the limiting member 310 and the first limiting groove 111 can be used to limit the stroke of the counterweight 300. The maximum stroke of the limiting member 310 along the first direction in the first limiting groove 111 is the maximum stroke of the counterweight block 300 in the first direction, that is, the first limiting groove 111 is used to limit the stroke of the counterweight block 300 to prevent the counterweight block 300 from exceeding the preset moving distance during the reciprocating movement, and to prevent the counterweight block 300 from being unable to reset and the equipment from being stuck due to the counterweight block 300 moving too long, so that the sliding of the counterweight block 300 is smoother and more stable, ensuring the normal use of the equipment.

[0050] In summary, the ultrasonic cutting equipment and machine tool of this embodiment have at least the following beneficial effects:

[0051] (1) The transducer 210 transmits high-frequency vibration to the blade 230 of the amplitude transformer 220, so that the blade 230 can vibrate ultrasonically at a high frequency in the axial direction. The blade 230 then adds ultrasonic high-frequency axial vibration to the original low-frequency axial reciprocating motion to improve the cutting speed and cutting ability of the blade 230.

[0052] (2) The counterweight 300 is slidably connected to the housing 100 via the slide rail 110, so that the counterweight 300 can reciprocate in the first direction, and at the same time, the counterweight 300 moves in the opposite direction to the cutting mechanism 200 to balance the inertial jitter generated by the cutting mechanism 200 during the reciprocating motion after the ultrasonic component is added to the cutting mechanism 200, thereby allowing the ultrasonic cutting device to achieve anti-shake, so that the blade 230 can cut the object more smoothly. The closer the sum of the weight of the counterweight 300 and the second output terminal 420 is to the sum of the weight of the cutting mechanism 200 and the first output terminal 410, the better the corresponding anti-shake effect, thereby reducing tool jitter and better achieving precise cutting.

[0053] (3) The slide rail 110 is provided with a first limiting groove 111, and the limiting member 310 of the counterweight 300 is stuck in the first limiting groove 111. Therefore, when the counterweight 300 moves, the limiting member 310 also moves together, and the cooperation between the limiting member 310 and the first limiting groove 111 can be used to limit the stroke of the counterweight 300. The maximum stroke of the limiting member 310 in the first limiting groove 111 along the first direction is the maximum stroke of the counterweight 300 in the first direction, that is, the stroke of the counterweight 300 is limited by the first limiting groove 111, so as to prevent the counterweight 300 from exceeding the preset moving distance during the reciprocating movement, and to prevent the counterweight 300 from being unable to reset and the equipment from being stuck due to the counterweight 300 moving too long. This makes the sliding of the counterweight 300 smoother and more stable, and ensures the normal use of the equipment.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
