Detailed implementation manners

[0033] The embodiment of the present application discloses a non-woven fabric slitting machine, wherein one end of the non-woven fabric on the reel 101 in the slitting machine body 100 passes through multiple groups of guide rollers 104 for discharge, and the traction roller 122 first moves along the gear belt 112 to pull one end of the non-woven fabric to be transported between the discharge rollers 125. During the traction process, the moving roller 114 first pre-irons the non-woven fabric, and after the non-woven fabric is pulled to the discharge roller 125 for fixing, the two groups of traction rollers 122 move in a direction away from the non-woven fabric. After moving to the initial state, the moving roller 114 moves again to the position of the discharge roller 125 and stops moving, so that it is in During the movement, the wrinkles on the surface of the non-woven fabric are ironed out again, and then the suction force of the suction cup 202 in the alignment plate 20 is used to align the two sides of the non-woven fabric, and the tension force is obtained during the alignment process, and the tension force of the discharge roller 125 is cooperated so that the non-woven fabric to be cut can be subjected to forces in four directions, thereby facilitating cutting. This solves the problem that the non-woven fabric is skewed and has size errors during the cutting process, and the wrinkles on the surface of the non-woven fabric affect the cutting quality of the non-woven fabric. The non-woven fabric is guided and tensioned during the cutting process to make its surface smooth for easy cutting, thereby improving the cutting quality.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figures 1-4 A non-woven fabric slitting machine comprises a slitting machine body 100 and a reel 101 arranged on the slitting machine body 100, on which non-woven fabric is wound, and a slitting blade 102 telescopically arranged on the slitting machine body 100, which is driven by a telescopic rod to move upward after slitting the non-woven fabric. Both sides of the slitting machine body 100 are fixedly connected with mounting frames 103, on which the slitting unit 1 is connected, and the slitting unit 1 is used to pull the non-woven fabric and It is tensioned and sheared, and the slitting unit 1 includes a moving component 11 arranged on a mounting frame 103, and the moving component 11 is used to roll the surface of the non-woven fabric to remove wrinkles, and the moving component 11 is connected to a traction component 12, and the traction component 12 is used to receive the non-woven fabric and pull and tension the non-woven fabric to facilitate cutting and unloading, and the moving component 11 and the traction component 12 are symmetrically arranged in two groups on the upper and lower surfaces of the non-woven fabric, so that the traction component 12 and the moving component 11 can better act on the non-woven fabric;

[0036] The nonwoven fabric is transported on the reel 101 through multiple groups of rolling rollers on the slitting machine body 100. After being transported to the position of the slitting blade 102, the surface of the nonwoven fabric is processed by the slitting unit 1 before being slit, so that the slitting effect is good.

[0037] Reference Figures 3-9, the moving component 11 includes a first driving gear 111 rotatably arranged on the mounting frame 103. The outer wall of the first driving gear 111 is meshed and connected with a gear belt 112. One end of the gear belt 112 far away from the first driving gear 111 is meshed and connected with multiple driven gears 113. A fixing rod 115 is fixedly connected to the gear belt 112, and a moving roller 114 is rotatably connected to the gear belt 112 through the fixing rod 115. The moving roller 114 is used to roll on the non-woven fabric. The moving roller 114 is arranged to be hollow, and a heating wire 116 is arranged inside the moving roller 114. The heating wire 116 is spiral-shaped and is used to heat and iron the surface of the non-woven fabric. The spiral shape increases the length of heat generation to heat the moving roller more evenly. The first driving gear 111 is driven by a first power device, and the first power device is preferably a motor, so that the first driving gear 111 rotates, and the moving roller 114 moves along the running track of the gear belt 112, thereby performing a wrinkle ironing treatment on the surface of the non-woven fabric;

[0038] The traction component 12 includes a connecting plate 121 slidably connected to the fixing rod 115. One end of the connecting plate 121 far away from the fixing rod 115 is rotatably connected to a traction roller 122. One side of the connecting plate 121 is connected to one end of an elastic member 123, and the other end of the elastic member 123 is connected to a mounting block 124. The elastic member 123 is preferably a spring. A discharging roller 125 is rotatably connected to the tail of the slitter body 100. The discharging roller 125 is used to receive the non-woven fabric and roll out the slit non-woven fabric;

[0039] It should be noted that the traction roller 122 and the moving roller 114 share the same motor, and the motor drives the gear belt 112 to run 2 circles, and 2 circles are a cycle. When the gear belt 112 runs the first circle, it is to make the traction roller 122 pull one end of the non-woven fabric to move. After moving to the position of the discharging roller 125, one end of the non-woven fabric is fixed by the discharging roller 125. Then, after the traction roller 122 follows the gear belt 112 back to the initial position, the moving roller 114 acts on the non-woven fabric again to perform rolling ironing on the surface of the non-woven fabric, thereby ironing the possible wrinkles on its surface;

[0040] The motor is installed on one side of the mounting plate. When the motor is started, it drives the first driving gear 111 to rotate. The rotation of the first driving gear 111 causes the gear belt 112 to move along the outer wall track of the first driving gear 111 and the driven gear 113. The number of driven gears 113 is three groups, and the shape of the gear belt 112 is rectangular, so that the moving roller 114 and the traction roller 122 are moved along the contour of the gear belt 112. First, the non-woven fabric is clamped by two groups of traction rollers 122 and driven to move toward the position of the discharge roller 125 under the movement of the traction roller 122. At this time, the moving roller 114 also rolls on the non-woven fabric to perform a rolling ironing process on the non-woven fabric. After moving to the position of the discharge roller 125, the traction roller 122 and the moving roller 114 move along the vertical direction of the gear belt 112 (that is, the two groups of traction rollers 122 and the moving roller 114 move in the vertical direction of the gear belt 112). The rollers 114 move in a direction away from the non-woven fabric to release the clamping of the non-woven fabric), and the traction roller 122 contacts the discharge roller 125 during the movement along the gear belt 112. When in contact, the traction roller 122 squeezes the elastic member 123, thereby rotating along the axis of the fixed rod 115 so that it does not interfere with the discharge roller 125, and continues to run along the gear belt 112. The restoring force of the elastic member 123 restores the traction roller 122 to its initial position, and when running along the gear belt 112 again, the non-woven fabric becomes a taut straight cloth under the tension of the discharge roller 125. The moving roller 114 runs again, and the internal heating wire 116 can transfer heat to the outer wall of the moving roller 114, so that it acts on the non-woven fabric, thereby better removing wrinkles on the surface of the non-woven fabric.

[0041] Embodiment 2

[0042] Reference Figures 1-4 An alignment unit 2 is provided on the slitting machine body 100 near the slitting blade 102. The alignment unit 2 includes a receiving assembly 21 provided at the bottom of the slitting machine body 100. The receiving assembly 21 is used to receive the non-woven fabric and support it during slitting. Alignment assemblies 22 are provided on both sides of the slitting blade 102 in the width direction. The alignment assembly 22 is used to tension and align both sides of the non-woven fabric to be slit.

[0043] The alignment unit 2 can further facilitate the slitting of the nonwoven fabric, making the slitting effect better.

[0044] Reference Figures 10-13The alignment component 22 includes a second driving gear 221 rotatably arranged on the top of the mounting frame 103, one end of the second driving gear 221 is meshedly connected with a first rack 222, and the first rack 222 is connected to a first alignment frame 223, and the other end of the second driving gear 221 is meshedly connected with a second rack 224, and the second rack 224 is connected to a second alignment frame 225, and the first alignment frame 223 and the second alignment frame 225 are both fixedly connected with an alignment plate 20, and the alignment plate 20 0 is used to align and tension the non-woven fabric in the width direction, and an alignment groove 201 is provided on the alignment plate 20, and multiple groups of suction cups 202 are evenly arranged on the top and bottom of the alignment groove 201 along its length direction. The second driving gear 221 is driven by a second power device, and the second power device is preferably a motor, which drives the second driving gear 221 to rotate so that the first alignment frame 223 and the second alignment frame 225 move toward each other, so that the alignment plate 20 can align and tension the non-woven fabric in the width direction;

[0045] After the traction roller 122 and the moving roller 114 process the nonwoven fabric (when the moving roller 114 runs along the gear belt 112 for the second time, it stops at the position of the discharge roller 125 and moves back to the initial position after the slitting blade 102 slits the nonwoven fabric), the motor starts, driving the second driving gear 221 to rotate, so that the first rack 222 and the second rack 224 meshing with it move toward each other, driving the first alignment frame 223 and the second alignment frame 225 to move toward each other at the same time, so that both sides of the nonwoven fabric in the width direction enter the alignment groove 201, and are adsorbed by the suction cup 202, thereby completing the alignment and tensioning of both sides in the width direction of the nonwoven fabric, so that it cooperates with the discharge roller 125, so that the nonwoven fabric to be slit can be in a taut state, so that it can be cut accurately;

[0046] It should be noted that the non-woven fabric enters the alignment groove 201, which is smaller than the width of the alignment groove 201, so that the non-woven fabric is close to the alignment groove 201 but does not completely enter. Therefore, when the non-woven fabric is sucked by the suction cup 202, the distance of the non-woven fabric in the width direction can be adjusted according to the suction, thereby achieving the alignment effect.

[0047] Reference Figures 2-3 The receiving assembly 21 includes a receiving block 211 disposed at the bottom of the slitting machine body 100, a knife groove 212 is provided on the receiving block 211, and the knife groove 212 coincides with the position of the slitting blade 102. A telescopic member 213 is fixedly connected to the bottom of the receiving block 211, and the telescopic member 213 is preferably a telescopic rod, which is used to drive the receiving block 211 to move up and down to avoid the moving roller 114;

[0048] When no slitting is performed, the receiving block 211 is retracted at the bottom of the moving roller 114 so that it does not affect the movement of the moving roller 114. When slitting is performed, the moving roller 114 is at the position of the discharge roller 125, and the telescopic part 213 is extended to drive the receiving block 211 to support the non-woven fabric. After the slitting blade 102 falls, it can also support the slitting blade 102, which can facilitate the slitting of the non-woven fabric.

[0049] How this application works:

[0050] The non-woven fabric on the reel 101 is pulled and moved through the plurality of guide rollers 104 for discharge. The pulling roller 122 moves along the gear belt 112 to pull the non-woven fabric to the discharge roller 125, and fixes the non-woven fabric under the rolling of the discharge roller 125. The pulling roller 122 moves along the gear belt 112 again to the initial position.

[0051] Rolling de-wrinkling: when the moving roller 114 is pulled by the pulling roller 122, the non-woven fabric is pre-de-wrinkled. When the moving roller 114 moves to the initial position and de-wrinkles along the non-woven fabric again, the non-woven fabric is pulled due to the fixation of the discharge roller 125, so that the de-wrinkling effect of the moving roller 114 on its surface is better.

[0052] Alignment and tensioning, (the moving roller 114 stops after moving to the position of the discharge roller 125) at this time, the first rack 222 and the second rack 224 move towards each other, approaching the two sides of the non-woven fabric, so that its side edges enter the alignment groove 201 (close but not completely entered, and the suction cup 202 is at a certain distance from the non-woven fabric, so that it cannot be sucked by the suction cup 202, but can be moved), and the suction cup 202 generates suction on the non-woven fabric, so that it can be aligned and tensioned;

[0053] Undertaking cutting, the receiving block 211 supports the non-woven fabric under the extension effect of the telescopic member 213. At this time, the slitting blade 102 moves downward to cut the non-woven fabric, and the knife groove 212 is used to support the slitting blade 102, so as to achieve a better slitting effect.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0055] What has been described above is only a preferred specific implementation manner of the embodiments of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
