[0032] The clamping and pulling mechanism 6 is located in front of the cutting mechanism 5. The clamping and pulling mechanism 6 is equipped with a clamping member that moves in the front-back direction. The clamping member is used to clamp the end of the fabric.

[0033] The "forward" direction mentioned in this article refers to the feed direction of the fabric belt, i.e. Figure 1 Center right, behind is Figure 1 The left-center and front-back directions are the length direction of frame 1, and the width direction of frame 1 is the axial direction of the cloth roll on the feeding rack 2.

[0034] Furthermore, the trimming mechanism 3 includes two first lifting cylinders 32, located on opposite sides of the frame 1 in the width direction. The cylinder bodies of the first lifting cylinders 32 are fixedly connected to the frame 1, and the output ends of the first lifting cylinders 32 are fixedly connected to a first support rod 33. At least one blade holder 34 is slidably mounted on the first support rod 33, and a trimming blade 31 is mounted on the blade holder 34. Preferably, a T-slot is provided along the length direction of the first support rod 33, and the blade holder 34 is fixed to a slider, which is slidably connected to the T-slot, thus creating a sliding connection between the two. Next, during actual edge trimming, the blade holder 34 can be positioned on the first support rod 33 by relying on friction. However, it is preferable to connect a tightening screw to the blade holder 34 by thread. The tightening screw passes through the blade holder 34 and abuts against the first support rod 33 for positioning. Preferably, there are two blade holders 34, which are used to trim the two sides of the fabric respectively. The trimming blade 31 is preferably a blade wheel structure. The blade wheel structure is rotatably connected to the blade holder 34. The blade wheel structure can also be independently connected to a motor fixed on the blade holder 34 to achieve self-rotation.

The inner end of the guide roller 42, that is, the end closest to the other guide roller 42, is on the same plane as the cutting plane of the edge trimmer 31, or is 0-5mm away from it, so that the cut between the main body of the fabric after trimming and the waste edge does not separate at a long distance, preventing the tearing force at an angle from pulling and deforming the main body of the fabric.

[0037] The winding motor 45 is preferably a servo motor. During use, the cut waste edge should not be in a taut state at the guide roller 42 and the winding roller 46 to prevent the fabric body from being stretched and deformed due to pulling.

The blade wheel structure is rotatably connected to the output end of the first linear motor 54. The blade wheel structure can also be independently connected to a motor fixed to the output end of the first linear motor 54 to achieve self-rotation.

[0039] Furthermore, the clamping and pulling mechanism 6 includes two second linear motors 61, which are located on both sides of the frame 1 in the width direction.

Several pneumatic fingers 63 are arranged at intervals on the rear side of the third support rod 62. The pneumatic fingers are existing technology and the clamping action is achieved by pneumatics. A platform 13 is arranged between the two second linear motors 61.

[0040] Both the trimming mechanism 3 and the cutting mechanism 5 are lifted and lowered independently by cylinders. In actual production, one of their functions can be used as needed, while the other function is raised by cylinders to avoid obstacles.

[0041] The working process of this utility model is as follows:

Fix the blade holder 34 in the appropriate position and lower the first lifting cylinder 32 so that the cutting blade 31 reaches the height that can cooperate with the fabric strip for cutting. At the same time, loosen the tightening screw 43 to adjust the position of the guide roller 42. As mentioned above, the inner end of the guide roller 42, that is, the end close to the other guide roller 42, is on the same plane as the cutting plane of the cutting blade 31, or is 0-5mm away from it. After adjusting it to the correct position, tighten the tightening screw 43 to position the guide roller 42.

[0044] S3. Lower the second lifting cylinder 52 so that the cutting blade 51 reaches a height that can be used to cut the fabric tape.

[0045] S4. The second linear motor 61 operates, pulling the fabric belt forward via the pneumatic finger 63, and stopping when it reaches the desired position.

[0046] S5. The first linear motor 54 operates, cutting the fabric strip through the cutting blade 51. The cut fabric strip falls onto the platform 13, the pneumatic finger 63 is released, the second linear motor 61 operates, driving the third support rod 62 to retract and clamp the end of the new fabric strip.

[0047] S6. The waste edge cut off by the trimming blade 31 is as follows Figure 3 The waste edge, which passes around the guide roller 42, changes from horizontal to vertical and is fixed to the take-up roller 46. It is driven to be wound up by the take-up motor 45. As mentioned above, the waste edge located between the trimming knife 31, the guide roller 42, and the take-up roller 46 should not be in a taut state.
