Therefore, they should not be construed as limitations on this utility model.
[0014] As attached Figure 1-2 As shown, a steel wire rolled cord type trimming knife device includes a linear trimming knife, and the linear trimming knife includes a trimming knife holder 9. The trimming knife holder 9 is preferably an arc-shaped structure plate as shown in the figure. A trimming knife wire 4 is provided on the trimming knife holder 9. The two ends of the arc-shaped structure of the trimming knife holder 9 are pressed against the trimming knife wire 4, so that the trimming knife wire 4 between the two ends of the trimming knife holder 9 serves as the trimming knife structure and as the working area. A pre-tightening seat 1 is fixedly connected to the side of the trimming knife holder 9. A pre-tightening mechanism is provided on the pre-tightening seat 1. The pre-tightening mechanism is fixedly connected to one end of the trimming knife wire 4 and is used to apply a pre-tightening force to the trimming knife wire 4. It also includes a quick disassembly and assembly device. A disassembly and assembly structure that cooperates with the quick disassembly and assembly device is provided on the side of the trimming knife holder 9.
[0015] Furthermore, one end of the trimming knife holder 9 is fixedly connected to the upper connecting plate 7, and the two are fixed by at least two bolts. The upper connecting plate 7 is fixedly connected to one end of the trimming knife wire 4. Preferably, the upper connecting plate 7 extends a connecting post to one side, and the trimming knife wire 4 is tied to the connecting post or clamped and fixed by a clamping device. The other end of the trimming knife holder 9 is fixedly connected to the guide wheel frame 5, and the two are fixed by at least two bolts. The guide wheel frame 5 has a hole, and a guide wheel shaft 6 passes through and is fixedly connected to the hole. A guide wheel 8 is rotatably connected to the guide wheel shaft 6. The outer periphery of the guide wheel 8 is provided with an embedding groove that cooperates with the trimming knife wire 4. The outer periphery of the guide wheel 8 is provided with a guide groove that adapts to the edge of the curtain. The other end of the trimming knife wire 4 passes around the guide wheel 8 and is fixedly connected to the pre-tightening mechanism.
[0016] Furthermore, a pre-tightening seat 1 is fixedly connected to the trimming knife holder 9 on the side of the guide wheel frame 5. A pre-tightening rod 3 is provided on the pre-tightening seat 1. One end of the pre-tightening rod 3 forms a connector 16 that is fixedly connected to the trimming knife wire 4. The connector 16 is connected to the linear trimming knife through a pin. This connection method allows the linear trimming knife to have a certain amount of movement during operation, avoiding damage caused by rigid connection. The other end of the pre-tightening rod 3 passes through the pre-tightening seat 1. The pre-tightening seat 1 has a sliding groove that mates with the pre-tightening rod 3 and is threaded with an adjusting nut 2. A preload spring 10 is provided between the adjusting nut 2 and the preload seat 1. The preload spring 10 is sleeved on the preload rod 3. The preload spring 10 is preferably made of chromium alloy steel, carbon spring steel, or high silicon content spring steel, which has greater rigidity and less deformation, and stronger stability. Alternatively, the preload spring 10 can be removed, and the adjusting nut 2 can abut against the preload seat 1 to form an adjusting structure. By directly changing the position of the adjusting nut 2, the trimming knife wire 4 can be tightened. This provides the strongest rigidity and the strongest stability, but the tension of the trimming knife wire 4 is difficult to adjust and is more prone to damage.
[0017] Preferably, the guide wheel frame 5 is provided with an adjustment hole for adjusting the position of the guide wheel shaft 6, and the guide wheel shaft 6 is fixed in the adjustment hole by fastening bolts. By adjusting the position of the guide wheel shaft 6 in the adjustment hole, the trimming requirements of curtain fabrics of different widths can be adapted, improving the versatility of the device.
[0018] Further details are attached. Figure 3 As shown, the quick-assembly device is a tool holder, which includes a base plate 34. Two parallel clamping plates 35 are fixed on the same side of the base plate 34, forming a gap between the two clamping plates 35 to cooperate with the trimming tool holder 9. The two clamping plates 35 are in clearance fit with the trimming tool holder 9. A first limiting bolt 31 and a second limiting bolt 32 are fixedly connected to the two clamping plates 35. The first limiting bolt 31 and the second limiting bolt 32 are threadedly connected to at least one of the clamping plates 35. The rear side of the trimming tool holder 9 is provided with a first opening groove 37 and a second opening groove 38 to cooperate with the first limiting bolt 31 and the second limiting bolt 32, respectively. One of the clamping plates is threadedly connected to a fastening bolt 33, which is fastened by abutting against the surface of the trimming tool holder 9. The base plate 34 has at least two through holes for inserting bolts for fixing to other tools.
[0019] The gap formed between the two clamping plates 35 serves as the mounting groove. Preferably, the inner wall of the mounting groove is provided with an anti-slip pad. The anti-slip pad can increase the friction between the linear trimming knife and the mounting groove, prevent the trimming knife from sliding during operation, and ensure the stability of trimming.
[0020] Furthermore, the opening directions of the first opening groove 37 and the second opening groove 38 form an angle α, where α ≥ 60°. Preferably, as shown in the figure, the second opening groove 38 is formed inward from the top edge of the rectangular plate, and the first opening groove 37 is formed inward from the side edge of the rectangular plate, forming a 90° angle with the opening direction of the second opening groove 38. The advantage of this design is that if the two opening grooves are in the same direction, they can be fixed by the tightening of the fastening bolt 33. With the vibration generated during use, the trimming knife holder 9 may still detach from the knife holder. This structure forms an effective limit. When disassembling, the fastening bolt 33 is loosened. Only two actions, one turn and one pull, are needed to separate the trimming knife holder 9 from the knife holder.
[0021] The pre-tightening device of the present invention can provide a stable and adjustable pre-tightening force, ensuring that the linear trimming knife maintains appropriate pressure during the trimming process, thereby improving the stability of trimming quality.
[0022] The trimming knife guide wheel device guides and positions the curtain fabric through guide wheels with guide grooves, effectively ensuring trimming accuracy and reducing trimming errors caused by curtain fabric offset.
[0023] The quick-release device enables rapid replacement of the linear trimming blade, greatly shortening the replacement time and improving equipment maintenance and production efficiency.
[0024] The device has a reasonable structural design for each component, strong versatility, and can adapt to the trimming needs of steel wire calendered cord fabrics of different specifications. It has high practical value and promising prospects for promotion.
[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
