DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 5 The present invention provides a device for cutting and removing burrs of textile cloth.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, a burr cutting and removing device for textile cloth includes a conveyor frame 100 , a cutting member 200 and a flattening member 300 .

[0035] The conveyor frame 100 has a cutting platform 101 for conveying the textile cloth through the cutting platform 101 for burr cutting.

[0036] Specifically, drive motors are installed at both ends of the conveyor frame 100, and the drive motors are connected to the rollers at the corresponding ends, and the two sets of motors synchronously drive the rollers at both ends of the conveyor frame 100 to rotate synchronously, so that the rollers at one end of the conveyor frame 100 convey the cut edges of the textile cloth, and the rollers at the other end convey the cut textile cloth out of the material.

[0037] The cutting member 200 has a cutting knife 210 for cutting the raw edges of the textile fabric passing through the cutting platform 101 .

[0038] Specifically, the cutting piece 200 is connected to the roller body at the feeding end of the conveying frame 100 through the conveying structure. The linear speed of the blade of the rotating cutting knife 210 at the lowest position is equal to the moving speed of the textile cloth during the conveying process, and the direction is consistent. The setting of the speeds of the two can be achieved by first measuring the conveying speed of the cloth and then adjusting the cutting knife 210 accordingly through the CNC system.

[0039] The flattening member 300 has flattening rollers 310 , which are installed on both sides of the cutting knife 210 and are used to flatten the textile cloth to be introduced under the cutting knife 210 .

[0040] Preferably, a rubber sleeve is provided on the outer end of the leveling roller 310 to increase the friction of the outer end of the leveling roller 310, so that the cloth is pulled outward synchronously for smoothing when the leveling roller 310 swings inward.

[0041] There are multiple groups of leveling rollers 310 , and the leveling rollers 310 rotate synchronously with the cutting knife 210 with the axis of the cutting knife 210 as the center of the circle. The leveling rollers 310 are swingably installed on both sides of the cutting knife 210 .

[0042] When the leveling roller 310 is about to rotate to the lowest position, the leveling roller 310 swings outward to the maximum extent. In the process of the leveling roller 310 reaching the lowest position, the outer end of the leveling roller 310 is supported by the cutting platform 101 and swings upward under the force of the cutting platform 101 to drag the textile fabrics on both sides of the cutting knife 210 to move outward synchronously.

[0043] Specifically, during the process of cutting the rough edges of the textile cloth, when the cloth is conveyed through the cutting platform 101, one group of leveling rollers 310 rotates to the lowest position, and the outer ends of the leveling rollers 310 begin to abut against the cutting platform 101 through the textile cloth, and the outer ends of the leveling rollers 310 begin to swing upward under the support of the cutting platform 101. During this process, since the textile cloth is always clamped between the leveling rollers 310 and the cutting platform 101, the distance between the outer ends of the two groups of leveling rollers 310 increases during the swinging of the leveling rollers 310 on both sides, thereby driving the textile cloth to move toward the two sides of the cutting knife 210, thereby achieving the effect of smoothing the textile cloth to be cut, and during this process, the textile cloth is pressed by the leveling rollers 310 on both sides, which can ensure that the textile cloth remains taut.

[0044] In this embodiment, the conveying frame 100 includes a body 110, a feed roller 120, an intermediate pressure roller 130 and a discharge roller 140. The feed roller 120, the intermediate pressure roller 130 and the discharge roller 140 are sequentially installed on the body 110, the cutting platform 101 is arranged between the feed roller 120 and the intermediate pressure roller 130, and the discharge roller 140 is located on the side of the intermediate pressure roller 130 away from the feed roller 120.

[0045] In this embodiment, the cutting member 200 includes a transmission member 220 , a tool holder 230 and a cutting knife 210 . The tool holder 230 is symmetrically installed on both sides of the cutting platform 101 , and the transmission member 220 is transmission-installed between the cutting knife 210 and the feeding roller 120 .

[0046] In this embodiment, the transmission member 220 includes a conveyor belt group 222 and a transmission shaft 224. One end of the conveyor belt group 222 is installed on the feed roller 120, and the other end is installed on the transmission shaft 224. The transmission shaft 224 is rotatably installed on the tool holder 230, and the cutting knife 210 is clamped and installed on the transmission shaft 224.

[0047] Preferably, in order to facilitate the removal and replacement of the cutting knife 210, a first locking knife clip is fixedly mounted on the transmission shaft 224, and a second locking knife clip is threadedly mounted thereon, the opposite surfaces of the first locking knife clip and the second locking knife clip have a locking knife groove, the surface of the cutting knife 210 has a locking knife block matching the shape of the locking knife groove, the cutting knife 210 is mounted between the first locking knife clip and the second locking knife clip, and the locking knife groove and the locking knife block are engaged to achieve the effect of the cutting knife 210 rotating synchronously with the transmission shaft 224.

[0048] like Figure 3As shown, in one embodiment, the leveling member 300 includes a support plate 320 and a swing member 330 . The support plate 320 is installed on the transmission shaft 224 and is located on both sides of the cutting knife 210 . The swing member 330 is installed between the support plate 320 and the leveling roller 310 .

[0049] like Figure 4 As shown, in one embodiment, the support plate 320 (see Figure 3 ) has a transfer hole 321.

[0050] Swinging member 330 (see Figure 3 ) includes a rotating block 332 and an adapter shaft 334, the adapter shaft 334 is installed in the adapter hole 321, the rotating block 332 is rotatably installed on the adapter shaft 334, and the rotating block 332 can rotate along the axial section of the support plate 320 relative to the adapter shaft 334.

[0051] Flattening element 300 (see Figure 1 ) also includes a corner locking member 340, a corner locking block 350 and an unlocking member 360 (see Figure 3 ), the corner locking piece 340 is installed on the rotating block 332, and the corner locking block 350 is fixedly installed on the surface of the supporting plate 320 away from the leveling roller 310.

[0052] In this embodiment, the corner locking member 340 (see Figure 3 ) includes a locking block claw 342 and a rebound member 344. The locking block claw 342 is rotatably mounted on the rotating block 332. The inner wall of the locking block claw 342 facing away from the rebound member 344 and the supporting plate 320 are enclosed to form a locking block space. The rebound member 344 is mounted on the rotating block 332 and is connected to the locking block claw 342.

[0053] Preferably, in order to facilitate the corner locking block 350 to enter the locking block space, the end of the locking block claw 342 adjacent to the entrance of the locking block space is processed into an arc surface.

[0054] Preferably, the support plate 320 has a through hole to provide displacement space for the locking block claw 342 to follow the rotation of the rotating block 332 .

[0055] In this embodiment, the resilient member 344 includes an abutment block and a spring member. One end of the locking block claw 342 adjacent to the entrance of the locking block space extends outward to form a pressing portion. The spring member is abutted and installed between the abutment block and the pressing portion.

[0056] Specifically, when the leveling roller 310 begins to abut against the cutting platform 101, the cutting platform 101 pushes the outer end of the leveling roller 310 to swing toward the support plate 320. During this process, the corner locking block 350 begins to shift from abutting against the arc-shaped end of the locking block claw 342 to moving into the locking block space.

[0057] When the leveling roller 310 rotates to the lowest position, the leveling roller 310 is driven by the cutting platform 101 to swing upward to the maximum amplitude. At this time, the locking block 350 is located in the locking block space, and the elastic force of the spring member pushes the locking block claw 342 to maintain contact with the locking block 350.

[0058] like Figure 5 As shown, in one embodiment, the unlocking member 360 includes an unlocking block 362 and an unlocking rod 364, the unlocking rod 364 is fixedly mounted on one end of the rotating block 332 away from the leveling roller 310, and the unlocking block 362 is mounted on the tool holder 230;

[0059] The unlocking block 362 has a driving surface on its surface adjacent to the unlocking rod 364 , and the unlocking rod 364 abuts against the driving surface to drive the leveling roller 310 to swing outward to the maximum amplitude.

[0060] Specifically, when the leveling roller 310 is about to enter the lowest position, the unlocking rod 364 on the group of leveling rollers 310 rotates with the support plate 320 until it abuts against the driving surface, and the unlocking rod 364 moves along the driving surface, causing the unlocking rod 364 to be driven to drive the leveling roller 310 to swing outward to the maximum extent, thereby providing space for the leveling roller 310 to be subsequently driven by the cutting platform 101 to swing upward. During this process, the unlocking rod 364 drives the locking block claw 342 to rotate synchronously through the rotating block 332, causing the locking block claw 342 to move relative to the locking angle block 350, so as to realize the passive separation of the locking angle block 350 from the locking block space.

[0061] Working principle: When the burrs of textile fabric are cut and removed, the cutting knife 210 rotates at high speed to cut off the burrs of the textile fabric passing by, the supporting plate 320 rotates synchronously with the cutting knife 210 through the transmission shaft 224, the supporting plate 320 drives the rotating block 332 through the adapter shaft 334, and the rotating block 332 drives the leveling roller 310 to rotate synchronously. When the leveling roller 310 abuts against the cutting platform 101, the leveling roller 310 in the initial state swings outward to the maximum amplitude, that is, the inner angle between the leveling roller 310 and the outer end of the supporting plate 320 is the smallest, which causes the outer end of the leveling roller 310 to start to swing upward under the support of the cutting platform 101, that is, at the same time with the leveling roller 310 The distance between the outer ends of the two groups of leveling rollers 310 abutting the cutting platform 101 increases until the leveling rollers 310 move to the lowest position and the distance between the outer ends of the two groups of leveling rollers 310 is the largest. At this time, the locking block 350 enters the locking block space, and the angle of the leveling roller 310 at the lowest position is locked. During this process, the outer end of the leveling roller 310 pulls the textile fabric below it to move outward, thereby causing the textile fabric in the cutting area of ​​the cutting knife 210 to be pulled to both sides to achieve a tightening effect in the middle area, thereby preventing the textile fabric from being too loose and being squeezed by the blade of the cutting knife 210 to form zipper-like wrinkles, thereby effectively improving the flatness of the textile fabric during the cutting process.

[0062] Furthermore, during the process of the leveling roller 310 rotating upward following the support plate 320, since the locking angle block 350 is locked in the locking block space, the angle of the leveling roller 310 relative to the support plate 320 remains unchanged. When the unlocking rod 364 begins to abut against the driving surface, the unlocking rod 364 is squeezed and displaced by the driving surface, causing the unlocking rod 364 to be driven to swing. The unlocking rod 364 drives the leveling roller 310 to swing outward to the maximum amplitude through the rotating block 332. During this process, the rotating block 332 drives the locking block claw 342 to swing synchronously, so as to pull the locking block claw 342 to rotate relative to the locking angle block 350, that is, to cause the locking angle block 350 to move out of the locking block space, thereby realizing the unlocking function of the angle of the leveling roller 310, and increasing the displacement space for the subsequent leveling roller 310 to be driven by the cutting platform 101 to swing upward again to pull the textile fabric.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
