Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: Figures 1-4As shown, the utility model provides a technical solution, including a workbench 1, a reeling roller 2 is installed on one side of the top surface of the workbench 1, vertical plates 3 are fixedly connected to both ends of the top surface of the workbench 1, a rotating roller 4 is rotatably connected between the outer walls of the adjacent ends of the two vertical plates 3, a support plate 5 is fixedly connected to the outer walls of the opposite ends of the two vertical plates 3, a positioning mechanism 6 is provided between the two support plates 5, and a slitting assembly 7 is provided between the two vertical plates 3;

[0023] The positioning mechanism 6 includes a bidirectional screw rod 61, which is rotatably connected between the outer walls of the two support plates 5 at one end. The outer surface of the bidirectional screw rod 61 is threadedly connected to two symmetrically distributed movable plates 62. Two symmetrically distributed through grooves 63 are penetrated through the outer wall of one end of the movable plate 62. Both side walls inside the through groove 63 are provided with a slide groove 64. A slider 65 is slidably connected inside the slide groove 64. A mounting block 66 is fixedly connected between the two sliders 65 in the same through groove 63. A positioning roller 67 is rotatably connected to the outer wall of one end of the mounting block 66. Two symmetrically distributed fixed blocks 68 are fixedly connected to the outer wall of one end of the movable plate 62. Two parallel springs 69 are fixedly connected between the top surface of the mounting block 66 and the bottom surface of the corresponding fixed block 68.

[0024] Further as Figure 1 and Figure 4 As shown, it is worth mentioning that the slitting assembly 7 includes a mounting box 71, which is fixedly connected between the outer walls of the two vertical plates 3 at one end. The top and bottom surfaces of the mounting box 71 are penetrated by guide grooves 72. Four moving blocks 73 are slidably connected inside the mounting box 71. The top surface of the moving block 73 is fixedly connected with a bolt 74, and the outer surface of the bolt 74 is threadedly connected with a locking nut 75. The bottom surface of the moving block 73 is fixedly connected with a fixing rod 76. The bottom end of the fixing rod 76 passes through the guide groove 72 located on the bottom surface of the mounting box 71 and is installed with a slitting knife 77.

[0025] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that a guide rod 8 is fixedly connected between the outer walls of the two support plates 5 at one end, a motor 9 is fixedly connected to the outer wall of one end of one of the support plates 5, and a rotating rod 10 is rotatably connected to the outer wall of the end of the movable plate 62 away from the positioning roller 67, and an extrusion rod 11 is fastened and sleeved on the outer surface of the rotating rod 10.

[0026] Further as Figure 1 and Figure 4 As shown, it is worth mentioning that the outer walls of the opposite ends of the two vertical plates 3 are fixedly connected with electric push rods 12, the output ends of the electric push rods 12 are fixedly connected with connecting blocks 13, and the tops of the outer walls of one end of the two vertical plates 3 are penetrated by movable grooves 14.

[0027] Further as Figure 2、 Figure 3 and Figure 4 As shown, it is worth mentioning that the top end of the bolt 74 extends to the outside of the mounting box 71 through the guide groove 72 located on the top surface of the mounting box 71, and the moving block 73 is locked and limited by the cooperation of the bolt 74 and the locking nut 75. The guide rod 8 slides with the two moving plates 62 to improve the stability of the moving plate 62 when moving. The extrusion rod 11 on the same moving plate 62 is located between the corresponding two mounting blocks 66. The two mounting blocks 66 on the same moving plate 62 are separated from each other by the rotation of the extrusion rod 11, which facilitates the non-woven fabric to pass through between the two positioning rollers 67 on the same moving plate 62.

[0028] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth mentioning that the output end of the motor 9 rotates through the corresponding support plate 5 and is coaxially fixedly connected to the outer wall of one end of the bidirectional screw rod 61. The bidirectional screw rod 61 is driven to rotate by the motor 9 to adjust the positions of the two movable plates 62. The outer walls of one end of the two connecting blocks 13 pass through the corresponding movable grooves 14 and are fixedly connected to the outer walls of the two ends of the installation box 71 respectively, so that the installation box 71 can be pushed to move by the electric push rod 12, so that the slitting knife 77 acts on the non-woven fabric.

[0029] In summary, when the slitting machine is in use, first, according to the width of the non-woven fabric, the motor 9 is turned on to drive the bidirectional screw rod 61 to rotate. Under the action of the thread, the bidirectional screw rod 61 drives the two movable plates 62 to move synchronously. When the distance between the two movable plates 62 is adjusted to match the width of the non-woven fabric, the rotating rod 10 is rotated to drive the extrusion rod 11 to rotate. When the extrusion rod 11 rotates, it pushes the corresponding two mounting blocks 66 to move in opposite directions. The two mounting blocks 66 drive the two positioning rollers 67 to move. At this time, the spring 69 is forced to shrink, and then one side of the non-woven fabric passes through the two positioning rollers 67. Then the rotating rod 10 is released, and the two mounting blocks 66 are pushed under the elastic action of the spring 69 to drive the two positioning rollers 67 to move close to each other, clamping and positioning the non-woven fabric. The rotating positioning rollers 67 play a conveying role when cutting the non-woven fabric, and the two movable plates 62 are operated in turn to position the two edges of the non-woven fabric. The operation is simple, which prevents the non-woven fabric from offsetting during the slitting process, and effectively avoids the problem that the non-woven fabric is easily offset during slitting and affects the slitting effect.

[0030] After the two edges of the non-woven fabric are positioned, the locking nut 75 is loosened to release the limit on the movable block 73 according to the width of the non-woven fabric to be cut. The position of the slitting knife 77 is adjusted by the sliding cooperation between the movable block 73 and the mounting box 71. After adjusting the position of each movable block 73 respectively, the locking nut 75 is re-tightened to re-lock and fix each movable block 73, so that the cutting width of the scoring slitting knife 77 reaches the required requirement. Then, one end of the non-woven fabric is passed around the rotating roller 4 and connected to the external winding device, and the two electric push rods 12 are turned on to pull the mounting box 71 downward through the connecting block 13, so that each slitting knife 77 acts on the non-woven fabric. After that, the external winding device is started to pull the non-woven fabric to move, and the non-woven fabric is cut when passing through the slitting knife 77, effectively avoiding the problem that the slitting machine is difficult to adjust the slitting spacing according to demand.

[0031] The motor 9 and the electric push rod 12 can be purchased on the market. The motor 9 and the electric push rod 12 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
