[0054] Please refer to Figure 1 and Figure 3 As shown, one embodiment of this application provides a testing device for detecting the lifespan of a rotary cutting needle, including a positioning base 100 and a support base 200. The support base 200 has a receiving cavity, and the positioning base 100 includes a positioning cavity 150 for positioning the rotary cutting needle 10. During the testing process, the rotary cutting needle 10 is stably installed in the testing device.

[0055] The detection device for detecting the life of the rotary cutting needle also includes a drive mechanism. The drive mechanism is located in the receiving cavity, which is connected to the positioning cavity 150. Part of the drive mechanism is located in the positioning cavity 150. When the rotary cutting needle 10 is installed in the positioning cavity 150, the drive mechanism is connected to the rotary cutting needle 10 and drives the movement of the rotary cutting needle 10. The rotary cutting needle 10 simulates the movement on the rotary cutting device, thereby realizing the detection of the life of the rotary cutting needle 10.

[0056] In some embodiments, the drive mechanism includes a drive assembly and a gear set connected together. The gear set is at least partially located within the positioning cavity 150 and is used to drive the rotary cutting needle 10. The gear set meshes with the rotary cutting needle 10, and the rotation of the gear set drives the movement of the rotary cutting needle 10.

[0057] In some embodiments, such as Figure 4As shown, the gear set includes a first gear 310, a second gear 320, and a third gear 330. The first gear 310 meshes with the rotary cutting needle 10 to drive it in axial reciprocating motion; the second gear 320 meshes with the rotary cutting needle 10 to drive it in circumferential rotation; and the third gear 330 meshes with the rotary cutting needle 10 to drive it in axial reciprocating oscillation. When the rotary cutting needle 10 operates in the rotary cutting equipment, it performs axial reciprocating motion, circumferential rotation, and reciprocating oscillation according to operational requirements. In the testing device used to detect the lifespan of the rotary cutting needle, the three types of gears drive the rotary cutting needle 10 respectively, simulating the operation process of the rotary cutting needle 10 in the rotary cutting equipment, thereby achieving the detection of the rotary cutting needle 10.

[0058] In some specific embodiments, the arrangement direction of the first gear 310, the second gear 320 and the third gear 330 is parallel to the axial direction of the rotary cutting needle 10 in the installed state, and a portion of the structure of the first gear 310, a portion of the structure of the second gear 320 and a portion of the structure of the third gear 330 protrudes from the first opening 110, which improves the compactness of the gear set and facilitates the drive mechanism to drive the three gears.

[0059] In some embodiments, such as Figure 4 As shown, the drive assembly includes a first drive unit for driving a first gear 310, a second drive unit for driving a second gear 320, and a third drive unit for driving a third gear 330. The first drive unit includes a first motor, a first motor shaft 410, and a fourth gear 420 mounted on the first motor shaft 410, which meshes with the first gear 310. The second drive unit includes a second motor, a second motor shaft 430, and a fifth gear 440 mounted on the second motor shaft 430, which meshes with the second gear 320. The third drive unit includes a third motor, a third motor shaft 450, and a sixth gear 460 mounted on the third motor shaft 450, which meshes with the third gear 330.

[0060] The first motor, the second motor, and the third motor output different power and rotation in different directions through their electric shafts, which in turn transmit the power to the first gear 310, the second gear 320, and the third gear 330 to produce different movements.

[0061] In some embodiments, such as Figure 4As shown, the drive structure also includes a housing 470, inside which the first motor, second motor, and third motor are housed. A support shaft 480 is also provided outside the housing 470. The first gear 310, second gear 320, and third gear 330 are mounted on the same support shaft 480, aligning the three gears in the same direction. By configuring the housing 470 and support shaft 480, the drive assembly and gear set are combined into a single drive mechanism mounted within the support base, satisfying the design that the first gear 310, second gear 320, and third gear 330 are located at the first opening 110.

[0062] In some specific embodiments, the support shaft 480 protrudes from one side wall of the motor housing 470, and the first motor shaft 410, the second motor shaft 430 and the third motor shaft 450 extend from the same side wall of the motor housing 470. The relative positions of the first motor shaft 410, the second motor shaft 430 and the third motor shaft 450 with the support shaft 480 meet the meshing requirements between gears.

[0063] In some embodiments, such as Figure 2 As shown, the positioning seat 100 includes a first opening 110, and the support seat 200 includes a second opening 220. The first opening 110 and the second opening 220 are arranged opposite to each other. Therefore, the gear set needs to pass through the first opening 110 and the second opening 220 to contact the rotary cutting needle 10 and drive the rotary cutting needle 10 to move.

[0064] In a specific embodiment, the positioning seat 100 is installed on the upper surface of the support seat 200, and the second opening 220 is opened on the upper surface of the support seat 200 to ensure the stability of the positioning seat 100. During the detection process, the rotary cutting needle 10 is not affected by other structural stresses, thus improving the detection accuracy.

[0065] It should be noted that the upper surface 210 of the support base 200 refers to the top surface of the detection device relative to other surfaces of the support base 200 when the detection device is placed upright on the horizontal platform during operation.

[0066] In one specific embodiment, the first opening and the second opening are located opposite to the gear set, and the gear set passes through the first opening 110 and the second opening 220.

[0067] In other embodiments, one side or top surface of the support base 200 is completely open, and the open side is a second opening 220. The positioning seat 100 is installed at the open second opening 220 of the support base 200. The positioning seat 100 closes the open side of the support base 200. After the gear part passes through the first opening 110, it can contact the rotary cutting needle 10.

[0068] In some embodiments, such as Figure 3As shown, the positioning base 100 also includes a base plate 120 and a support structure 130. The base plate 120 is mounted on the upper surface 210 of the support base 200. The support structure 130 protrudes from the base plate 120 and matches the rotary cutting needle 10 to engage the rotary cutting needle 10. The first opening 110 faces the interior of the support structure 130. The support structure 130 engages the rotary cutting needle 10 through structural matching, while ensuring that the rotary cutting needle 10 has the degrees of freedom to simulate operation.

[0069] The support structure 130 is a semi-enclosed protrusion, and the semi-enclosed space is a positioning cavity 150. The positioning cavity 150 is a cylindrical space, and the axis of the rotary cutting needle 10 is the same as the axis of the cylindrical space. Therefore, after the rotary cutting needle 10 is engaged in the positioning cavity 150, its radial movement is fixed, but it also has the freedom of axial and circumferential movement, which can complete the simulated action on the rotary cutting device. The first opening 110 faces the interior of the support structure 130, and the gear set at the first opening 110 drives the rotary cutting needle 10 to move axially and circumferentially.

[0070] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the testing device for detecting the lifespan of the rotary cutting needle also includes multiple screws for mounting the drive structure and the positioning seat 100. The positioning seat 100 has a first mounting hole 140, the drive mechanism has a second mounting hole 490, the outer surface of the support seat 200 has a third mounting hole 260, and the inner surface of the support seat 200 has a fourth mounting hole 270. Some screws pass through the first mounting hole 140 and the second mounting hole 490 to fix the positioning seat 100; other screws pass through the second mounting hole 490 and the fourth mounting hole 270 to fix the drive mechanism.

[0071] In a specific embodiment, both the third mounting hole 260 and the fourth mounting hole 270 are provided on the structure of the upper surface 210 of the support base 200. The positioning seat 100 is located outside the upper surface 210 of the support base 200, and the drive structure is located inside the upper surface 210. The support shaft 480 of the drive structure extends to the position opposite to the first opening 110 and the second opening 220, causing part of the gear set structure to protrude outside the second opening 220, thereby driving the rotary cutting needle 10.

[0072] In some embodiments, such as Figure 1 and Figure 2As shown, the testing device for detecting the lifespan of the rotary cutting needle also includes a screen 500, on which the test results can be displayed and the user can also operate and set test parameters. The support base 200 also includes a screen mounting groove 230, the opening of which faces the outside of the support base 200. The screen 500 is engaged in the screen mounting groove 230, placing the structure of the screen 500 in the thickness direction in the screen mounting groove 230 so that the display part of the screen 500 is almost flush with the surface of the support base 200, which can improve the aesthetics of the testing equipment and the convenience of operating the screen 500.

[0073] In some embodiments, the screen mounting slot 230 further includes a power port 231, which is formed on the slot wall of the screen mounting slot 230 and is used to connect the screen 500 and the interior of the support base 200. The power wires supplying power to the screen 500 pass through the power port 231, and the signal lines for information transmission also pass through the power port 231, so that power is supplied and information is exchanged in the support base 200.

[0074] In some embodiments, such as Figure 5 As shown, the support base 200 also includes a base 240, on which a circuit board 250 is mounted. The base 240 forms the lower surface of the support base 200, and the circuit board 250 is mounted on the side of the base 240 facing inwards from the support base 200. The circuit board 250 also includes a power interface 251, a screen interface 252, and a motor interface 253, all mounted on it. The power interface 251 is used to connect to an external power supply. A screen 500 connection cable is also provided to connect the screen 500 to the screen interface 252; a motor connection cable is also provided to connect the drive mechanism to the motor interface 253. The detection device is connected to the outside world via the power interface 251, supplies power to the screen 500 via the screen 500 connection cable, and supplies power to the drive mechanism via the motor connection cable.
