Description

[0001] This application relates to the field of fabric cutting equipment technology, and in particular to an adaptive fabric cutting equipment. Background Technology

[0002] When using fabrics for production, it is usually necessary to cut the fabric into pieces according to processing requirements. Currently, cutting fabrics typically requires the use of a cutting machine. However, cutting machines can usually only cut one piece of fabric at a time, resulting in low cutting efficiency. To address this, related technical fields have explored stacking multiple pieces of fabric for simultaneous cutting, effectively improving cutting efficiency. However, because fabrics are inherently soft, and some even have a sticky texture, they are prone to shifting during the cutting process, which can easily lead to deviations between the cut fabric shape and the intended shape, resulting in poor cutting quality.

[0021] like Figures 1 to 8 As shown, this application provides an adaptive fabric cutting device, including a reciprocating drive mechanism 1, a cutting mechanism 2, and a clamping mechanism 3. The reciprocating drive mechanism 1 includes a reciprocating drive frame 11, a first reciprocating driver 12, and a second reciprocating driver 13, both of which are mounted on the reciprocating drive frame 11. The cutting mechanism 2 includes a cutting frame 21 and a cutter 22, with the cutting frame 21 disposed between the first reciprocating driver 12 and the second reciprocating driver 13, and the cutter 22 mounted on the cutting frame 21. The clamping mechanism 3 includes a placement platform 31, two equally divided variable-pitch modules 32, and multiple elastic abutment components 33. The placement platform 31 is placed on the surface of the cutting frame 21 and reciprocates along a first direction under the drive of the first reciprocating driver 12 and the second reciprocating driver 13. The two equally divided variable-pitch modules 32 are both mounted on the placement platform 31, and the multiple elastic abutment components 33 are both mounted between the two equally divided variable-pitch modules 32 and are equally divided and varied along the first direction under the drive of the two equally divided variable-pitch modules 32. The elastic abutment components 33 include a fixing plate 331, a through hole 332, and two elastic abutment members 333. The fixing plate 331 is mounted between the two equally divided variable-pitch modules 32, the through hole 332 is opened in the fixing plate 331, and the two elastic abutment members 333 are both mounted on the fixing plate 331 and are respectively arranged on both sides of the through hole 332 along the first direction.

[0022] It should be noted that the "first direction" above and below refers to the bidirectional direction of the shortest connection between the first reciprocating driver 12 and the second reciprocating driver 13, specifically as follows: Figure 1 The X-axis is shown in the diagram; the second direction below refers to the bidirectional direction of the shortest line connecting the two equally divided pitch modules 32, as shown in the diagram. Figure 1 The Y-axis is shown below; the third direction below refers to the bidirectional direction of the shortest line connecting the fixed plate 331 and the elastic support member 333, specifically as follows: Figure 1 The Z-axis is shown in the figure.

[0023] This application provides a fabric cutting adaptive cutting device. Under the action of a first reciprocating drive 12, a placement platform 31 can be driven to pass under a cutter 22. Under the action of the cutter 22, the fabric on the surface of the placement platform 31 can be cut through the cutter hole 332. Driven by two equally spaced variable-distance modules 32, the distance between any two adjacent fixed plates 331 can be adjusted, and the distance between any two adjacent fixed plates 331 can be kept equal, thereby enabling the cutting of fabrics of different sizes and improving the applicability of the device. Under the action of two elastic abutment components 33, when the cutter 22 cuts multiple layers of fabric, the multiple layers of fabric are tightly held against the surface of the placement platform 31, thereby preventing fabric displacement and improving cutting efficiency while ensuring cutting quality.

[0024] Optionally, both the first reciprocating drive 12 and the second reciprocating drive 13 are configured as electric cylinders.

[0025] In one embodiment of this application, please refer to Figures 1 to 8 The elastic support member 333 includes multiple support rods 3331, a support plate 3332, and multiple first elastic structures 3333. The multiple support rods 3331 are all inserted through the fixed plate 331. The support plate 3332 is installed at one end of the multiple support rods 3331 near the placement platform 31. The multiple first elastic structures 3333 are sleeved on the multiple support rods 3331 and abut against the fixed plate 331 and the support plate 3332, and are arranged in a one-to-one correspondence with the multiple support rods 3331.

[0026] This configuration, with the action of multiple supporting rods 3331, ensures that the supporting plate 3332 can only move along a third direction, thus allowing it to smoothly hold the multi-layered fabric against the surface of the placement platform 31, resulting in excellent holding effect. The action of multiple first elastic structures 3333 ensures that the supporting plate 3332 always has a tendency to move towards the placement platform 31 along a third direction, thereby holding the multi-layered fabric against the platform 31 and preventing fabric displacement. Through the combined action of the multiple supporting rods 3331 and the multiple first elastic structures 3333, the supporting plate 3332 can be used to hold multi-layered fabrics of different thicknesses, further expanding the applicability of the device.

[0027] Optionally, the elastic support member 333 includes a plurality of stops 3334, which are installed at the ends of the plurality of support rods 3331 away from the support plate 3332 and are configured to correspond one-to-one with the plurality of support rods 3331.

[0028] With this configuration, the stop block 3334 can limit the support rod 3331, preventing the support rod 3331 from detaching from the fixing plate 331.

[0029] Optionally, the first elastic structure 3333 is configured as a spring or a sheet.

[0030] In one embodiment of this application, please refer to the following: Figures 1 to 8 The cutting mechanism 2 also includes a first recess 23 and a first guide surface 24. Both the first recess 23 and the first guide surface 24 are formed in the cutting frame 21. The first guide surface 24 is used to guide the placement platform 31 to move out of the first recess 23. The placement platform 31 includes a base plate 311, a placement plate 312, multiple support rods 313, multiple limiting blocks 314, and multiple second elastic structures 315. The base plate 311 is placed on the surface of the cutting frame 21, the placement plate 312 is placed on the base plate 311, the multiple support rods 313 are installed on the placement plate 312 and pass through the base plate 311, the multiple limiting blocks 314 are installed at the ends of the multiple support rods 313 away from the placement plate 312 and are arranged one-to-one with the multiple support rods 313, and the multiple second elastic structures 315 are sleeved on the multiple support rods 313 and abut against the placement plate 312 and the multiple limiting blocks 314, and are arranged one-to-one with the multiple support rods 313.

[0031] With this configuration, when the base plate 311 is above the first clearance groove 23, multiple second elastic structures 315, multiple limiting blocks 314, and multiple support rods 313 can drive the placement plate 312 towards the base plate 311 to increase the distance between the placement plate 312 and the supporting plate 3332. This facilitates the placement of multiple layers of fabric on the surface of the placement plate 312, preventing the supporting plate 3332 from contacting the placement plate 312 and making it impossible to place the fabric, thus improving ease of use. Under the action of the first guide surface 24, the limiting blocks 314 can guide the placement plate 312 towards the supporting plate 3332, preventing the first clearance groove 23 from interfering with the movement of the placement platform 31. Under the action of the limiting block 314, the second elastic structure 315 can be prevented from detaching from the support rod 313, which helps to improve the structural stability between the second elastic structure 315 and the support rod 313. Furthermore, under the action of the limiting block 314, the elastic force of the second elastic structure 315 can be transmitted to the placement plate 312, so that the placement plate 312 always has the tendency to move away from the abutment plate 3332. When the bottom plate 311 is aligned with the first clearance groove 23, the placement plate 312 can automatically move away from the abutment plate 3332, which is convenient to use.

[0032] Optionally, the second elastic structure 315 is configured as a spring or a sheet.

[0033] In one embodiment of this application, see [reference] Figures 1 to 8The placement plate 312 includes a plate body 3121, multiple magnetic strips 3122, two pressure strips 3123, and multiple magnetic blocks 3124. The multiple magnetic strips 3122 are all embedded in the plate body 3121 and are arranged at intervals along the second direction. The two pressure strips 3123 are located at both ends of the plate body 3121 along the first direction and are located on the side of the plate body 3121 facing the elastic support component 33. Multiple magnetic blocks 3124 are embedded in the pressure strips 3123, and the multiple magnetic blocks 3124 and the multiple magnetic strips 3122 are arranged in a one-to-one correspondence.

[0034] With this configuration, after placing multiple layers of fabric on the surface of the plate 3121, the pressing strip 3123 can press the multiple layers of fabric onto the surface of the plate 3121 under the magnetic attraction of the magnetic strips 3122 and magnetic blocks 3124, thereby fixing the multiple layers of fabric and preventing them from moving during rotation, which also helps to improve the cutting quality. Furthermore, under the action of multiple magnetic strips 3122 and multiple magnetic blocks 3124, the pressing strip 3123 can move relative to the plate 3121 along a first direction, while maintaining a tendency to move towards the plate 3121, thus fixing fabrics of different lengths and further expanding the applicability of the device.

[0035] In one embodiment of this application, please refer to Figures 1 to 8 An adaptive fabric cutting device includes a rotating mechanism 4 mounted on a cutting frame 21 and used to drive a base plate 311 to rotate about a third direction. The cutting mechanism 2 also includes two limiting brackets 25, both mounted on the cutting frame 21 and configured to limit two equally divided variable-distance modules 32 when the rotating mechanism 4 drives the base plate 311 to rotate about a third direction.

[0036] With this configuration, the rotating mechanism 4 can drive the multi-layered fabric to rotate around a third direction, thus enabling the cutting of multi-layered fabric from two different directions to complete the cutting process. This achieves a high degree of automation and ease of use. The two limiting brackets 25 prevent multiple elastic support components 33 from rotating with the multi-layered fabric during rotation, thereby preventing the cutting hole 332 from misaligning with the cutter 22 and ensuring normal cutting.

[0037] In one embodiment of this application, please refer to the following: Figures 1 to 8 The base plate 311 has multiple positioning holes 316. The rotating mechanism 4 includes a rotating driver 41, a rotating platform 42, and multiple positioning drivers 43. The rotating driver 41 is mounted on the cutting frame 21, the rotating platform 42 is mounted on the rotating driver 41, and rotates around a third direction under the drive of the rotating driver 41. The multiple positioning drivers 43 are all mounted on the rotating platform 42 and are configured to snap the base plate 311 onto the rotating platform 42 through the multiple positioning holes 316, and are set one-to-one with the multiple positioning holes 316.

[0038] With this configuration, when rotating multi-layer fabric, multiple positioning drivers 43 extend their output ends into multiple positioning holes 316, which can engage the base plate 311 with the rotating platform 42. Through the rotation driver 41, the base plate 311 can be rotated, thereby realizing the rotation of multi-layer fabric. It has a high degree of automation and is easy to use.

[0039] Optionally, the rotary driver 41 is configured as a motor. The positioning driver 43 is configured as an electric cylinder.

[0040] In one embodiment of this application, see [reference] Figures 1 to 8 The rotating platform 42 is provided with a second clearance groove 44 and a second guide surface 45. The second guide surface 45 is used to guide the base plate 311 to move out of the second clearance groove 44.

[0041] With this configuration, under the action of the second clearance groove 44, multiple second elastic structures 315, multiple limiting blocks 314, and multiple support rods 313 can drive the placement plate 312 towards the base plate 311 to increase the distance between the placement plate 312 and the supporting plate 3332. This prevents the multi-layered fabric from contacting the supporting plate 3332 during rotation, thus avoiding displacement of the multi-layered fabric and affecting the cutting quality. Under the action of the second guide surface 45, the interference of the second clearance groove 44 with the movement of the base plate 311 can be avoided, allowing the base plate 311 to move out of the second clearance groove 44 normally.

[0042] In one embodiment of this application, please refer to Figures 1 to 8 The base plate 311 has an annular slot 317. The equal-division pitch module 32 includes an equal-division pitch driver 321, two support legs 322 and two locking blocks 323. The two support legs 322 are installed at both ends of the equal-division pitch driver 321, and the two locking blocks 323 are installed at the ends of the two support legs 322 away from the equal-division pitch driver 321, and are both locked in the annular slot 317, and are set one-to-one with the two support legs 322.

[0043] With this configuration, under the action of the annular slot 317 and the four slot blocks 323, the base plate 311 can only rotate relative to the two equally divided pitch actuators 321 around a third direction, which helps to improve the rotational stability of the base plate 311 in the third direction, and also helps to improve the structural stability between the base plate 311 and the two equally divided pitch actuators 321.

[0044] In one embodiment of this application, please refer to the following: Figures 1 to 8 The limiting bracket 25 includes a fixed frame 251 and a limiting plate 252. The fixed frame 251 is installed on the cutting machine frame 21, and the limiting plate 252 is installed on the fixed frame 251 and is used to prevent the equally divided variable pitch module 32 from rotating around a third direction.

[0045] With this configuration, the limiting plate 252 can prevent the equally divided pitch module 32 from rotating around a third direction, allowing the base plate 311 to rotate normally relative to the two equally divided pitch modules 32.

[0046] In one embodiment of this application, see [reference] Figures 1 to 8 The limiting plate 252 includes a baffle 2521 and a guide plate 2522. The guide plate 2522 is connected to the end of the baffle 2521 near the cutter 22 and is bent relative to the baffle 2521 toward the fixing frame 251.

[0047] With this configuration, under the action of the guide plate 2522, it is easy for the two equally divided pitch modules 32 to enter between the two baffles 2521, and the situation where the limiting plate 252 interferes with the movement of the equally divided pitch modules 32 along the first direction is avoided.

[0048] The working principle of the adaptive fabric cutting device provided in this application is as follows: First, the multi-layered fabric needs to be placed on the surface of the plate 3121. Under the action of the second reciprocating actuator 13, the placement platform 31 is driven along the first direction to above the first clearance groove 23. With the combined action of multiple second elastic structures 315, multiple limiting blocks 314, and multiple support rods 313, the plate 3121 and the supporting plate 3332 separate, allowing the worker to place the multi-layered fabric between them. After placement, the worker adjusts the distance between the fixing plates 331 according to the predetermined cutting shape using the equal-division variable-pitch actuator 321. After adjustment, the worker presses two pressure strips 3123 onto both ends of the multi-layered fabric. Under the action of the first reciprocating drive 12, the placement platform 31 moves toward the cutter 22 along the first direction. Under the action of the first guide surface 24, through multiple second elastic structures 315, multiple limiting blocks 314, and multiple support rods 313, the base plate 311 gradually moves toward the abutment plate 3332 along the third direction until all the multiple limiting plates 252 are moved out of the first clearance groove 23. At this time, the multi-layer fabric is held between the plate 3121 and the multiple abutment plates 3332. The first reciprocating drive 12 continues to drive the placement platform 31 to move toward the cutter 22 along the first direction until the through hole 332 is aligned with the cutter 22. The first reciprocating drive 12 stops driving, and the cutter 22 cuts the multi-layer fabric through the through hole 332. This cycle repeats, and the cutter 22 cuts the multi-layer fabric multiple times through the multiple through holes 332. After multiple cuts, the first reciprocating drive 12 continues to drive the placement platform 31 to move towards the rotating mechanism 4 in the first direction until the base plate 311 aligns with the second clearance groove 44. Under the combined action of multiple second elastic structures 315, multiple limiting blocks 314, and multiple support rods 313, the multi-layer fabric and the supporting plate 3332 separate. At the same time, the output shafts of multiple positioning drives 43 enter multiple positioning holes 316. The rotary drive 41 drives the rotating platform 42 to rotate 90° around the third direction. After the rotation is completed, the multiple positioning drives 43 retract their output shafts. Under the action of the second reciprocating drive 13, the placement platform 31 moves towards the cutter 22 along the first direction. Under the action of the second guide surface 45, through multiple second elastic structures 315, multiple limiting blocks 314, and multiple support rods 313, the base plate 311 gradually moves towards the abutment plate 3332 along the third direction until all the limiting plates 252 are moved out of the second clearance groove 44. At this time, the multi-layer fabric is again held between the plate 3121 and the multiple abutment plates 3332. The second reciprocating drive 13 continues to drive the placement platform 31 to move towards the cutter 22 along the first direction until the through hole 332 is aligned with the cutter 22. The second reciprocating drive 13 stops driving, and the cutter 22 cuts the multi-layer fabric through the through hole 332. This cycle repeats, and the cutter 22 cuts the multi-layer fabric multiple times through the multiple through holes 332. Thus, the cutter 22 cuts the multi-layer fabric multiple times from two different directions, and the fabric is cut into shape.The second reciprocating drive 13 continues to drive the placement platform 31 to move along the first direction toward the first clearance groove 23 until the base plate 311 moves above the first clearance groove 23. The worker can then remove the cut fabric from the plate 3121.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this application should be included within the protection scope of this application.
