[0002] A slitting mechanism for knitted fabric production is a device used to cut knitted fabric to different sizes, effectively cutting the fabric to the required dimensions. Chinese Patent CN212916682U discloses a slitting mechanism for knitted fabric production. It includes a frame, a worktable, a cutter bar, a slitting blade mechanism, a motor, a blade edge cleaning brush, and a dust collection unit. The worktable is mounted on the frame, and the cutter bar is connected above it. Several slitting blade mechanisms are mounted on the cutter bar, each consisting of a first slitting blade assembly and a second slitting blade assembly. The inner side of the first slitting blade assembly is a clamp, and the outer side of the clamp is fixedly connected to the slitting blade. The motor is connected to a drive pulley, and a driven pulley is mounted above the drive pulley. The drive pulley and the driven pulley are connected by a transmission belt. A blade edge cleaning brush is mounted above the cutter bar, and a dust collection unit is mounted above the blade edge cleaning brush. Regarding the aforementioned related technology, the inventors have found at least the following problems: adjusting the slitting components requires stopping the machine and manual operation, which is cumbersome, affects work efficiency, and poses a safety hazard. Therefore, it is necessary to design and modify the knitted fabric production slitting mechanism to facilitate adjustment and effectively prevent the inconvenience of adjustment.

[0005] The beneficial effects of this utility model are as follows:

[0006] 1. This utility model uses a first rotating shaft that can slide left and right on the surface of the drive rod. When the operator needs to adjust the distance between the two blades, the operator starts the first motor to rotate, which drives the positive and negative threaded rod to rotate, thereby causing the movable blocks on both sides to move closer or further apart. The movement of the movable blocks will drive the support block, the first rotating shaft and the blades to move, thereby causing the blades on both sides to move closer or further apart. The operator can start the second motor to rotate, which drives the second rotating shaft and the drive rod to rotate. The rotation of the drive rod can drive the first rotating shaft and the blades to rotate, thereby cutting the knitted fabric.

[0007] 2. This utility model, through the setting of the cleaning component, has the blade and elastic bristles in contact, and the elastic bristles clean the blade. The operator can start the fan so that the gas and the debris generated during cutting enter the air chamber through the air inlet pipe and are then filtered by the filter plate.

The front of the filter plate 18 extends to the front of the wind chamber 17 and is fixedly connected with a pull rod.

[0015] In this embodiment, the cleaning component 13 is used to make the blade 9 fit with the elastic bristles 15. The elastic bristles 15 clean the blade 9. The operator can start the fan so that the gas and the debris generated during cutting enter the air chamber 17 through the air inlet pipe 16 and are then filtered by the filter plate 18.

[0016] refer to Figure 1 , Figure 3 and Figure 4The support frame 2 has openings 19 on both the front and rear sides. A slider 20 is movably connected inside the opening 19.

[0017] In this embodiment, the arrangement of opening 19, slider 20, first pressure roller 21, second pressure roller 23 and spring 22, under the action of spring 22, makes the first pressure roller 21 and the second pressure roller 23 fit tightly together, thereby clamping and positioning the knitted fabric, so that the blade 9 can accurately cut the knitted fabric. When cutting the knitted fabric, the knitted fabric is located between the first pressure roller 21 and the second pressure roller 23 and is in a tensioned state.

The top of the limit strips 24 is fixedly connected to the collection box 25. The front of the collection box 25 is fixedly connected to the handle.

[0019] In this embodiment, the collection box 25 can collect large-volume debris generated during cutting by setting the limiting groove, limiting strip 24 and collection box 25. The collection box 25 can be installed in the correct position by setting the limiting groove and limiting strip 24.

[0021] In this embodiment, the operator can adjust the height of the movable column 26, the support column 27, the slot, and the bolt 28 by setting up the movable column 26, thereby adjusting the height of the support plate 1 and the support frame 2, and thus adjusting the height of the device. Then, the operator can rotate the bolt 28 to insert the bolt 28 into the slot, thereby locking the position of the movable column 26 and thus locking the height of the device.

[0022] refer to Figure 1 The bottom of the support column 27 is fixedly connected to the base plate 29, which is fixedly connected to the air chamber 17. The bottom of the base plate 29 is fixedly connected to the four sides of the cylinder 30. The cylinder 30 is internally threaded with a first threaded rod 31, and the bottom of the first threaded rod 31 is fixedly connected to the support pad 32.

[0023] In this embodiment, by setting up a base plate 29, a cylinder 30, a first threaded rod 31 and a support pad 32, the operator can rotate the first threaded rod 31, thereby moving the first threaded rod 31 and the support pad 32 up or down, and thus adjusting the horizontal state of the base plate 29.

[0024] The first rotating shaft 7 can slide left and right on the surface of the drive rod 11. When the operator needs to adjust the distance between the two blades 9, the operator starts the first motor 5 to rotate, which drives the positive and negative threaded rod to rotate, thereby driving the movable blocks 4 on both sides to move closer or further apart. The movement of the movable blocks 4 will drive the support block 6, the first rotating shaft 7 and the blades 9 to move, thereby causing the blades 9 on both sides to move closer or further apart. The operator can start the second motor 12 to rotate, which drives the second rotating shaft 10 and the drive rod 11 to rotate. The rotation of the drive rod 11 can drive the first rotating shaft 7 and the blades 9 to rotate, thereby cutting the knitted fabric. When adjusting the position of the two blades 9, this device has the advantages of simple operation, safe operation process and high adjustment efficiency.
