Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology, and more particularly to a fabric cutting device. Background Technology

[0002] Fabric raw materials are usually in coiled rolls. When cutting and processing fabric raw materials, an automatic fabric spreading machine is generally used to pull the fabric to a suitable length before cutting. However, after feeding the fabric raw materials into the existing fabric spreading machine, the fabric raw materials are prone to misalignment with the spreading module. In addition, the spreading module of the existing fabric spreading machine has the problem of asynchronous spreading between the left and right sides. Both of these factors cause the fabric pulled out when using the existing fabric spreading machine to easily shift to the left or right, resulting in the final cut fabric having insufficient size and failing to meet the requirements of fabric cutting and processing.

[0015] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0016] Please see Figures 1 to 4 This utility model discloses a fabric cutting device, which includes: The rolling device 1 includes a rolling frame 11, a first support 12, and a transverse drive module 13. A first guide rail 14 extending laterally is provided on the upper side of the first support 12. The rolling frame 11 is slidably connected to the first guide rail 14. The transverse drive module 13 is fixedly connected to the first support 12. The drive end of the transverse drive module 13 is connected to the rolling frame 11. The transverse drive module 13 is used to drive the rolling frame 11, on which the roll of fabric 100 is placed, to move laterally left and right. The fabric pulling device 2 includes a second support 21, a gripper module 22, and a synchronous drive module 23. The second support 21 has a second guide rail 24 on each of its two laterally opposite side walls. The gripper module 22 includes a third support 221 and multiple gripper pieces 222 spaced laterally on the third support 221. The gripper pieces 222 are used to grip the front end of the front section of the rolled fabric 100. The two ends of the third support 221 are slidably connected to the two second guide rails 24 of the second support 21 at their lateral ends. The synchronous drive module 23 includes a first drive motor 231 fixedly connected to the second support 21 and a connecting... The connecting rod 232 and two transmission components 233 respectively disposed on opposite sides of the second bracket 21 in the lateral direction are connected. The driving end of the first drive motor 231 is connected to the connecting rod 232. The two ends of the connecting rod 232 in the lateral direction are respectively connected to the two transmission components 233. The two transmission components 233 are respectively connected to the two ends of the third bracket 221 in the lateral direction. The first drive motor 231 is used to control the rotation of the connecting rod 232 to drive the two transmission components 233 to drive the two ends of the third bracket 221 to slide synchronously along the second guide rail 24 in a direction away from the rolling device 1, so as to drive the gripper 222 to lay the front part of the rolled fabric 100 onto the second bracket 21. The cutting device 3 is mounted on the second support 21 and arranged between the rolling frame 11 and the gripper module 22. The cutting device 3 is used to cut the tail end of the front section of the rolled fabric 100.

[0017] Compared with the prior art, the rolling frame 11 of this utility model, which holds the rolled fabric 100, can slide laterally left and right on the first guide rail 14 of the first support 12 under the drive of the transverse drive module 13, so that the two sides of the fabric can be accurately aligned with the gripper module 22 of the fabric pulling device 2. The gripper 222 of the gripper module 22 clamps the front end of the front section of the rolled fabric 100 pulled out. The first drive motor 231 of the synchronous drive module 23 is connected to both ends of the second support 21 of the fabric pulling device 2 through the connecting rod 232 and the two transmission components 233, so that both ends of the second support 21 of the fabric pulling device 2... Driven by the synchronous drive module 23, the two second guide rails 24 on both sides of the second support 21 can slide synchronously away from the rolling device 1, thereby enabling the gripper 222 to synchronously pull the two sides of the front section of the rolled fabric 100 and lay the front section of the rolled fabric 100 on the second support 21. The above structure aligns the two sides of the fabric with the gripper module 22, and the gripper 222 synchronously pulls the two sides of the fabric, which can effectively prevent the fabric from shifting to the left or right, and is conducive to the cutting device 3 to accurately cut the tail end of the front section of the rolled fabric 100.

[0018] See Figures 1 to 4The synchronous drive module 23 also includes a first driving wheel 234, a first driven wheel 235, and a first belt wound around the first driving wheel 234 and the first driven wheel 235. The first driving wheel 234 is fixedly connected to the drive end of the first drive motor 231, and the first driven wheel 235 is fixedly connected to the middle part of the connecting rod 232. The transmission assembly 233 includes a first transmission wheel 2331, a second transmission wheel, and a transmission belt wound around the first transmission wheel 2331 and the second transmission wheel. The first transmission wheels 2331 of the two transmission assemblies 233 are respectively fixedly connected to the two ends of the connecting rod 232. The second transmission wheels of the two transmission assemblies 233 are respectively rotatably connected to the two sides of the second bracket 21 in the lateral direction. The two ends of the third bracket 221 in the lateral direction are respectively fixedly connected to the middle part of the upper layer of the transmission belt of the two transmission assemblies 233.

[0019] Specifically, in this embodiment, the gripper 222 is a gripper cylinder, and the first drive motor 231 is a rotary motor. Under the connection of the connecting rod 232, the third bracket 221 is simultaneously driven to slide along both ends in the lateral direction through the belt transmission structure. This allows each gripper 222 of the gripper module 22 on the third bracket 221 to synchronously pull the front end of the front section of the rolled fabric 100 under the drive of the first drive motor 231, so that the front section of the rolled fabric 100 is accurately laid on the second bracket 21 without any left or right deviation.

[0020] See Figures 1 to 4 The lateral movement drive module 13 includes a connecting frame 131 fixedly connected to the first bracket 12, a second drive motor, a second driving wheel, a second driven wheel 132, and a second belt 133 wound around the second driving wheel and the second driven wheel 132. The second driving wheel and the second driven wheel 132 are respectively rotatably connected to the two opposite ends of the connecting frame 131 in the lateral direction. The drive end of the second drive motor is fixedly connected to the second driving wheel. The rolling frame 11 is fixedly connected to the middle of the upper layer of the second belt 133. The second drive motor is used to drive the second driving wheel to rotate to drive the second belt 133 to drive the second belt 133 to move the rolling frame 11 in the lateral direction.

[0021] Specifically, in this embodiment, the rolling frame 11 is provided with a plurality of support rollers 111 arranged along a semi-circular arc, so that the rolled fabric 100 can be squeezed and rolled in the rolling frame 11 when it is pulled. In conjunction with the second drive motor driving the rolling frame 11 to move left and right through the belt transmission structure, the rolled fabric 100 can be pulled out in one direction, which is beneficial to the precise cutting of the subsequent cutting device 3.

[0022] See Figures 1 to 4The second bracket 21 has a longitudinally extending support frame 211 on the side facing the rolling frame 11, and a transversely extending third guide rail 212 on the side facing the gripper module 22. The cutting device 3 includes a cutting module 31, which includes a cutting machine 310, a support plate 311, a third drive motor 312, a third drive wheel 313, a third driven wheel 314, and a third belt wound around the third drive wheel 313 and the third driven wheel 314. The cutting machine 310 is supported by... Plate 311 is slidably connected to the third guide rail 212. The third driving wheel 313 and the third driven wheel 314 are respectively set at both ends of the support frame 211 along the lateral direction. The driving end of the third drive motor 312 is fixedly connected to the third driving wheel 313. The support plate 311 is fixedly connected to the middle of the upper layer of the third belt. The third drive motor 312 is used to drive the third driving wheel 313 to rotate to drive the third belt transmission, so that the cutting machine 310 moves laterally and cuts the tail end of the front section of the rolled fabric 100.

[0023] Specifically, in this embodiment, the second drive motor is a rotary motor, which drives the cutting machine 310 to move left and right along the third guide rail 212 through a belt drive structure. This helps the cutting machine 310 to cut the fabric smoothly and improves the accuracy of cutting the fabric.

[0024] Furthermore, the support frame 211 is provided with an opening 213 extending laterally. The front section of the rolled fabric 100 is pulled out through the opening 213 and extends longitudinally toward the gripper module 22. The cutting device 3 also includes a fabric pressing module 32, which includes at least two drive cylinders 321, a first pressure plate 322, and a second pressure plate 323. The first pressure plate 322 is fixedly connected to the drive ends of the two drive cylinders 321. The first pressure plate 322 and the second pressure plate 323 are respectively disposed on both sides of the opening 213 along the vertical direction. The drive cylinders 321 are used to drive the first pressure plate 322 to move vertically toward the second pressure plate 323 so that the tail end of the front section of the rolled fabric 100 is pressed onto the second pressure plate 323 by the first pressure plate 322. This helps to maintain the flatness of the cut end of the front section of the rolled fabric 100 and helps the cutting device 3 to cut the fabric accurately.

[0025] See Figures 1 to 4 The second bracket 21 has multiple connecting rollers 214 arranged vertically on the side wall facing the rolling frame 11. The front part of the rolled fabric 100 is pulled out vertically and passes around the connecting rollers 214 before extending longitudinally toward the gripper module 22, so that the rear part of the rolled fabric 100 is wrapped around the connecting rollers 214. This helps to further keep the rolled fabric 100 pulled out in one direction and avoid left and right deviation.

[0026] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
