[0002] Knitted fabric is a type of fabric that is made by interlacing yarns, usually by a knitting process on a textile machine. Knitted fabric has greater elasticity and softness than other types of fabrics.
[0003] Before the fabric is rolled up, it is necessary to trim the edges of the fabric so that the rolled fabric will be more integrated. Generally speaking, the edge of the fabric is trimmed by the cutting mechanism during the moving feeding process.
[0004] However, for knitted fabrics, which have high elasticity, it is easy to be stretched and deformed under the action of a large external force when the fabric is driven to move. If the edges are cut in this deformed state, when the fabric is restored later without external tension, the width of the fabric will increase, and the edge of the fabric will have a certain curvature along its length instead of a straight line. Summary of the invention

They are relative concepts and may change accordingly according to their different positions and different usage states.

[0027] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.
[0028] The embodiment of the present application discloses a fabric cutting and finishing device.
[0029] Reference Figure 1 A fabric cutting and finishing device includes a rotating drum 11, a cutting guide plate 2, a clamping roller group 4 and a winding drum 7. The fabric roller group to be cut is installed on the rotating drum 11, and then the fabric is allowed to wrap around the cutting guide plate 2 to allow the fabric to droop freely. The freely drooping end then passes through the clamping roller group 4 and is then wound around the winding drum 7. The fabric between the clamping roller group 4 and the cutting guide plate 2 is in a free drooping state. At this time, the fabric is not subjected to too much external force and remains loose.
[0030] Reference Figure 1 A support frame 1 is provided at both ends of the rotating drum 11. The support frame 1 has a built-in motor, which can drive the rotating drum 11 to rotate, so that the fabric on the rotating drum 11 can be unfolded.
[0031] Reference Figure 1The support frame 1 is rotatably provided with a cantilever 12, the rotation axis of the cantilever 12 is colinear with the rotation axis of the rotating cylinder 11, and the cantilever 12 can swing relative to the rotating cylinder 11 when rotating. One end of the cantilever 12 away from the support frame 1 is fixedly connected to the cutting guide plate 2, and as the cantilever 12 swings, the cutting guide plate 2 can rotate relative to the rotating cylinder 11.
[0032] Reference Figure 2 The cantilever 12 is provided with a plurality of first sockets 13, the support frame 1 is provided with a second socket 14, a latch 15 is provided between the second socket 14 and any one of the first sockets 13, after the latch 15 is pulled out, the cantilever 12 can be rotated on the support frame 1, after the latch 15 is simultaneously inserted into the second socket 14 and any one of the first sockets 13, the cantilever 12 no longer swings relative to the support frame 1.
[0033] Reference Figure 2 Furthermore, by adjusting the rotation amplitude of the cantilever 12, the height difference between the rotating cylinder 11 and the cutting guide plate 2 can be adjusted. The rotation of the rotating cylinder 11 can allow the fabric to unfold. The fabric between the cutting guide plate 2 and the clamping roller group 4 hangs freely. Due to the gravity of the fabric itself, the fabric will be transported toward the cutting guide plate 2 during the unfolding of the rotating cylinder 11. When the fabric itself is heavy, the cantilever 12 can be rotated to reduce the height difference between the rotating cylinder 11 and the cutting guide plate 2. When the fabric itself is light, the height difference between the rotating cylinder 11 and the cutting guide plate 2 can be increased. By changing the height difference, the fabric can be automatically transported from the rotating cylinder 11 to the cutting guide plate 2 under the action of its own weight. The fabric is subjected to only a small external force, thereby maintaining a relaxed state.
[0034] Reference Figure 3 A cutter disc 21 and a driving member 22 are provided at both ends of the cutting guide plate 2. The driving member 22 is a motor. The output shaft of the driving member 22 is fixedly connected to the rotating shaft of the cutter disc 21. The driving member 22 is a motor that can drive the cutter disc 21 to rotate. As the fabric is transported, the cutter disc 21 can cut the edge of the fabric.
[0035] The cutting guide plate 2 is provided with a knife groove 23 , and part of the knife disc 21 is located in the knife groove 23 , so that the knife disc 21 can be lower than the outer surface of the cutting guide plate 2 , thereby facilitating the cutting of the fabric by the knife disc 21 when the fabric slides over the cutting guide plate 2 .
[0036] Reference Figure 3The cutting guide plate 2 is also provided with a pressure plate 24, which is located on both sides of the knife groove 23. A gap is left between the pressure plate 24 and the cutting guide plate 2 for the fabric to pass through. The pressure plate 24 can slightly press the fabric without compacting the fabric, thereby facilitating the cutter disc 21 to cut the fabric. The position where the pressure plate 24 is connected to the cutting guide plate 2 is located on the side of the cutter disc 21 away from the rotating cylinder 11. After the cutter disc 21 cuts the fabric, the scraps will be cut off, so that the pressure plate 24 can be connected to the cutting guide plate 2 and the pressure plate 24 is located on the upper surface of the fabric.
[0037] Reference Figure 3 The cutting guide plate 2 is rotatably provided with an anti-sway rod 25, the anti-sway rod 25 is connected to the cutting guide plate 2 through a torsion spring, and one end of the anti-sway rod 25 is pressed against the upper surface of the edge of the fabric.
[0038] Furthermore, since the fabric is mainly transported by its own weight, in the process of being transported from the rotating drum 11 to the cutting guide plate 2, the edge of the fabric will also be slightly wrinkled and drooped due to its own weight. The anti-sway bar 25 can lightly press the edge of the fabric. On the one hand, it is convenient for the edge of the fabric to enter between the pressure plate 24 and the cutting guide plate 2. On the other hand, before the fabric enters the pressure plate 24 and the cutting guide plate 2, slight wrinkles can also be smoothed.
[0039] Reference Figure 4 and Figure 5 , the clamping roller group 4 is lower than the cutting guide plate 2, which is convenient for the fabric to droop freely. However, if the fabric is too light, although the fabric can droop freely, it will be blown by the wind, causing the free drooping position to swing. At this time, the lower pressing roller 3 is placed on the upper surface of the fabric between the cutting guide plates 2. Thereby increasing the dead weight of the fabric, the lower pressing roller 3 is a hollow plastic tube with a light weight, and will not cause excessive deformation of the fabric due to being too heavy. The fabric can also remain relaxed when being pressed by the lower pressing roller 3. The dotted arrows in this application indicate the position and conveying direction of the fabric.
[0040] Reference Figure 4 and Figure 5 The two ends of the lower pressing roller 3 are fixed with anti-slip convex rings 31, and the lower pressing roller 3 will roll when the fabric is transported. The anti-slip convex rings 31 can prevent the lower pressing roller 3 from being separated from the fabric when rolling.
[0041] Reference Figure 4 and Figure 5 The fabric between the clamping roller set 4 and the cutting guide plate 2 hangs freely and has a lowest position, which is lower than the clamping roller set 4. When the lower pressing roller 3 is placed, the position where the lower pressing roller 3 presses the fabric is the lowest position.
[0042] Reference Figure 6The clamping roller group 4 includes a clamping frame 41, a rotating roller 42 and a counterweight roller 43. Both ends of the rotating roller 42 are freely rotatably arranged on the clamping frame 41. The counterweight roller 43 is located directly above the clamping roller. The clamping frame 41 is provided with an adjustment slot 44. Both ends of the counterweight roller 43 are freely rotatably arranged in the adjustment slot 44. Both ends of the counterweight roller 43 are also provided with weight adjustment components 5. The adjustment slot 44 allows the counterweight roller 43 to move up and down, so that the fabric can pass between the counterweight roller 43 and the rotating roller 42. The counterweight roller 43 and the rotating roller 42 can clamp the fabric. The counterweight roller 43 has a certain weight. According to the weight of the counterweight roller 43, the clamping force of the clamping roller group 4 on the fabric is adjusted.
[0043] Reference Figure 6 The weight adjustment component 5 includes a sliding sleeve 51, an adjusting knob 52, a connecting plate 53 and an adjusting tension spring 54. The sliding sleeve 51 can be sleeved on the end of the counterweight roller 43 so that the counterweight roller 43 can rotate relative to the sliding sleeve 51, and the sliding sleeve 51 can slide up and down along the adjusting groove 44. The adjusting knob 52 is threadedly connected to the clamping frame 41. A connecting plate 53 is provided at the lower end of the adjusting knob 52. The connecting plate 53 cooperates with the adjusting knob 52 to prevent it from falling off. As the adjusting knob 52 rotates, the connecting plate 53 will not rotate, but can move up and down. The upper end of the adjusting tension spring 54 is connected to the connecting plate 53, and the lower end is connected to the sliding sleeve 51.
[0044] When the weight of the counterweight roller 43 needs to be adjusted, the adjusting knob 52 is turned, the connecting plate 53 will move upward or downward, and the adjusting tension spring 54 will be subjected to pressure or thrust. At this time, the adjusting spring can pull the counterweight roller 43 to offset the deadweight of the counterweight roller 43, or further press the counterweight roller 43 to increase the gravity of the counterweight roller 43.
[0045] A material receiving bucket 6 is also provided directly below the cutter disc 21 to collect the cut scraps.
[0046] The implementation principle of the embodiment is as follows: unfold the fabric, let the lower surface of the fabric contact the cutting guide plate 2, and the fabric between the cutting guide plate 2 and the clamping roller set 4 can droop freely. The fabric is cut in a relaxed state. The clamping roller set 4 can clamp the fabric, and the winding drum 7 can be rotated to wind the fabric. Since the clamping roller set 4 clamps the fabric, when the winding drum 7 actively rotates, the fabric between the clamping roller set 4 and the winding drum 7 has a certain tension, which is convenient for the winding of the winding drum 7.
[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application; therefore, according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the above specific implementation modes and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention. Therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
