The right side of the slitting assembly 2 is the right end of the slitting machine support 1 and serves as the curtain fabric outlet end, with the rear guide roller 4 mounted on it. During operation, the curtain fabric enters from the curtain fabric inlet end and exits from the curtain fabric outlet end, passing through the slitting assembly 2 and being cut into several curtain fabric strips by the slitting assembly 2.

[0035] like Figures 1 to 2 As shown, the slitting machine support 1 is provided with several bearing seats 11 and a fixing plate 12; wherein, the fixing plate 12 is fixedly connected to the top center of the slitting machine support 1, and a horizontally arranged slide rail 13 is provided on the fixing plate 12, so that the slitting assembly 2 can be slidably connected to the fixing plate 12 by setting the slide rail 13.

[0036] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the above-mentioned slitting component 2 specifically includes a blade holder and several cutting blades 21. The blade holder includes an upper blade holder 221, a lower blade holder 222, and a movable blade holder 223. A first slider 25 that can engage with the slide rail 13 is provided at the bottom of the movable blade holder 223. The movable blade holder 223 is slidably connected to the slide rail 13 through the first slider 25.

[0037] A slot 224 is provided on the left end of the movable blade holder 223, and a support plate 225 is provided on the right end of the movable blade holder 223. The upper blade holder 221 is arranged horizontally on the left side of the support plate 225. Several vertically arranged and evenly distributed blade slits 226 are provided on the upper blade holder 221, and the blade slits 226 penetrate radially through the upper blade holder 221. The top end of the cutter 21 is fixedly connected in the blade slits 226.

[0038] The aforementioned lower blade holder 222 is horizontally positioned on top of the movable blade holder 223 and below the upper blade holder 221. Several blade grooves 227 are provided on the right side of the lower blade holder 222; the number and position of the blade slots 226 and 227 correspond to each other. When the top end of the cutter 21 is fixed in the blade slot 226, the bottom end of the cutter 21 can be positioned within the blade groove 227.

[0039] like Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, an axial through hole 228 is arranged on the top end of the upper tool holder 221, the through hole 228 penetrates all the tool slots 226, and a rod 229 is inserted in the through hole 228. In order to better fix the cutting knife 21 on the upper tool holder 221, a hole 211 is arranged on the top end of the cutting knife 21, when the cutting knife 21 is fixed on the upper tool holder 221, the hole 211 on the cutting knife 21 is on the same axis with the through hole 228, at this time, the rod 229 penetrates through the through hole 228 and the hole 211 at the same time.

[0040] In order to ensure the stability of the rod 229, the two ends of the rod 229 protrude from the two end portions of the upper tool holder 221, and a limiting block 230 is arranged on the two ends of the rod 229, by arranging the limiting block 230, the rod 229 cannot fall off from the two ends of the upper tool holder 221, the limiting block 230 can be fixed by plug-in or threaded connection.

[0041] In order to better ensure that the cutting knife 21 can cut the cord fabric, an included angle is arranged between the moving tool holder 223 and the support plate 225, the included angle is towards the cord fabric guide-in end, and the included angle is 40°-60°.

[0042] As shown, Figures 1 to 3 The cutting assembly 2 is also provided with a cylinder 23 and a guide rail 24, the guide rail 24 is vertically arranged on the left side of the support plate 225, and the cylinder 23 is arranged on the left side of the support plate 225 and above the upper tool holder 221; wherein, a thrust end 231 is arranged on the bottom end of the cylinder 23, the thrust end 231 is fixedly connected to the upper tool holder 221, and a second sliding block 26 is arranged on the right side of the upper tool holder 221, the second sliding block 26 can be slidingly connected to the guide rail 24.

[0043] When the cutting knife 21 is in the cutting state for a long time, the blade of the cutting knife 21 cutting the cord fabric will be damaged, in order to ensure that the cutting knife 21 can be used for a long time, it is necessary to move the cutting knife 21, so that the blade cutting position of the cutting knife 21 changes, thereby prolonging the service life of the blade. By arranging the cylinder 23 connected to the upper tool holder 221 on the support plate 225, when the cylinder 23 is started, the thrust end 231 on the cylinder 23 will move upward or downward, and since the upper tool holder 221 is slidingly connected to the support plate 225, the cylinder 23 can indirectly drive the upper tool holder 221 to move up and down, thereby changing the blade cutting position of the cutting knife 21, thereby increasing the service life of the cutting knife 21, and indirectly reducing the equipment expenditure of replacing the cutting knife 21.

[0044] Among them, 3-5 gears can be arranged on the cylinder 23, which can more conveniently change the blade cutting position of the cutting knife 21.

[0045] According to the above description, the cutter 21 will move up and down, in order to ensure that the cutter 21 will not be stuck and cannot move when moving, therefore the width of the cutter slot 227 on the lower cutter holder 222 is greater than the width of the cutter slot 226 on the upper cutter holder 221, which makes the cutter 21 move more smoothly.

[0046] Based on the above description of the slitting assembly 2, in order to ensure that the slitting assembly 2 can cut the same size of the cord fabric when cutting the cord fabric, the cutter 21 and the cutter 21 are kept a certain distance, which is 9.54mm. This setting can increase the yield from 21 to 22 of 210mm wide cord fabric.

[0047] In order to ensure the stability of the moving cutter holder 223 and the upper cutter holder 221 when moving, the slide rail 13, the guide rail 24, the first slide block 25 and the second slide block 26 are all set to at least two groups.

[0048] As shown in Figures 1 to 4 The front end guide roller 3 is arranged at the cord fabric guide end of the slitting machine support 1, and it includes a guide roller 31 and a centering roller 32. The guide roller 31 is transversely arranged at the left end of the slitting machine support 1, and the two ends of the guide roller 31 are provided with a stop ring 33, which can move on the guide roller 31. A bolt hole is arranged on the outer diameter of the stop ring 33, and a bolt is arranged in the bolt hole of the stop ring 33. When the width of the cord fabric is different from the width between the two end stop rings 33 of the guide roller 31, the stop ring 33 can be moved by loosening the bolt, so that the distance between the two end stop rings 33 is the same as the width of the cord fabric. At this time, the bolt is locked and abuts against the guide roller 31, so as to fix the stop ring 33.

[0049] The above-mentioned centering roller 32 is transversely arranged in the slot 224, and at this time the position of the centering roller 32 is fixed and it can only rotate according to its shaft body. A stop ring 34 is fixed or integrally connected at both ends of the centering roller 32, and the distance between the two stop rings 34 is the same as the width of a single size of cord fabric. When the size of the cord fabric changes, the corresponding centering roller 32 needs to be replaced.

[0050] As shown in Figures 1 to 4 When the cord fabric is arranged on the guide roller 31, the cord fabric needs to be moved to the position corresponding to the cutter 21 at this time. At this time, in order to facilitate the movement of the cord fabric, a plurality of uniformly distributed hole grooves 311 are arranged on the ring surface of the guide roller 31, and a plurality of ball bearings 312 are filled in the hole grooves 311. At this time, the cord fabric arranged on the guide roller 31 can move up and down and left and right better. The hole grooves 311 are located between the two end stop rings 33.

[0051] As shown in Figures 1 to 2As shown, the rear end guide roller 4 is arranged at the cord guide-out end driving roller 41, the first passive roller 42 and the second passive roller 43 of the fabric splitting machine support 1; the driving roller 41 is arranged at the bottom of the fabric splitting machine support 1, and the first passive roller 42 and the second passive roller 43 are arranged at the top of the fabric splitting machine support 1, and the driving roller 41 is located between the first passive roller 42 and the second passive roller 43, which can increase the overall traction.

[0052] As shown, the two ends of the guide roller 31, the driving roller 41, the first passive roller 42 and the second passive roller 43 are provided with the bearing seat 11, and the bearing seat 11 is arranged on the fabric splitting machine support 1.

[0054] The cord cutting process of the present patent is as follows:

[0055] The cord is transported from the cord guide-in end to the cutting assembly 2 for cutting, and then transported to the cord guide-out end after cutting, and the cord is in a high-speed motion state during the process.

[0056] Specifically, first, adjust the width between the two end blocking rings 33 of the guide roller 31 to be the same as the width of the cord; then, the cord passes through the guide roller 31, the centering roller 32 and the cutting assembly 2 in sequence, and the guide roller 31 is used to preliminarily position the cord before splitting; since the cord is in a high-speed motion state, the state of the cord will change during the motion, and when the position of the cord changes, the blocking rings 34 on both ends of the centering roller 32 will receive force, and the cord will drive the centering roller 32 and the cutting assembly 2 to move together when the force is received, at this time the cutter 21 on the cutting assembly 2 can still cut according to the weft of the cord.

[0057] The cut cord passes through the first passive roller 42, the driving roller 41 and the second passive roller 43 in sequence, and is then transported out of the cord guide-out end. The split cord after being transported out is layered up and down according to the odd and even positions, so as to better process the cord splitting.
