[0048] The working principle of the slitting machine is mainly based on slitting the large roll mother roll into products of different widths, and ensuring the slitting accuracy and consistency of product length in the process.

[0049] First, a large roll of paper, film or other thin material is guided by a roller system into the loading area of ​​the slitting machine, and then unrolled. During this process, sensors or visual systems will accurately locate the material to ensure the accuracy of the cutting point; and the slitting length can be continuously set as needed.

[0050] After the material is positioned, the slitting machine uses a cutter to cut the material. After cutting, the waste material is discharged by air flow or vacuum suction, and the required material is guided by the guide roller at the rear to the winding roller.

[0051] Finally, the cut material is reeled up by the reel.

[0052] like Figure 1-Figure 4 As shown, the utility model proposes a slitting machine cutting knife mechanism with automatic adjustment, which is mainly used for the cutter on the above-mentioned slitting machine for cutting materials, wherein the automatic adjustment means that there is no need for manual adjustment by workers. The position of the cutter is adjusted with high precision through automated equipment to achieve accurate slitting of materials, thereby obtaining materials of the width we need.

[0053] The automatically adjustable slitting machine cutting mechanism of the present application is described in detail through the following embodiments.

[0054] Embodiment 1:

[0055] like Figure 1-Figure 4 As shown, in this embodiment, the cutting mechanism is installed inside the casing of the slitting machine; it includes:

[0056] The rotary shaft 100 is horizontally mounted on the two side panels 1 in the chassis, and its two ends can rotate;

[0057] The cutters 200 have several groups and are arranged adjustably along the axial direction of the rotary shaft 100, and are used to cut the material into the material of the required width;

[0058] The first power device 300 is used to drive the rotary shaft 100 to rotate so as to adjust the position of the cutter 200 located on the rotary shaft 100. By adjusting the position of the cutter 200, the material can be cut.

[0059] The device further comprises: a second power device 400 for controlling the position of each cutter 200 on the rotary shaft 100 .

[0060] In the slitting system, precise adjustment of the position of the cutter 200 is crucial, as it directly affects the cutting quality and production efficiency of the product. For this reason, the present application uses automation to adjust the position of the cutter 200 to achieve precise positioning of the position of the cutter 200, thereby improving the slitting accuracy of the material.

[0061] Specifically, the second power device includes:

[0062] The clamp 410 has two clamping parts 412 for clamping or releasing the cutter 200; wherein the clamp 410 is mainly composed of a double-headed cylinder 411 and two clamping parts 412, the two ends of the double-headed cylinder 411 are located on both sides thereof, and the two clamping parts 412 are respectively arranged on the two ends of the double-headed cylinder 411, and the two clamping parts 412 clamp or release the cutter 200 by the extension and contraction state of the double-headed cylinder 411;

[0063] And a driving part 420, used for driving the clamp 410 to move along the axial direction of the rotating shaft 100; wherein the driving part 420 is mainly composed of a screw module 421, a motor 422 and a sliding seat 423, the two ends of the screw module 421 are fixed on the two side panels 1 of the chassis, the motor 422 is fixed on one of the side panels 1 of the chassis, and is connected to the screw on the screw module 421, the sliding seat 423 is connected to the nut on the screw module 421, and the clamp 410 is installed on the sliding seat 423. When the motor 422 is running, it drives the screw to rotate, and then drives the sliding seat 423 and the clamp 410 to do linear motion.

[0064] When the position of the cutter 200 needs to be adjusted, the control system first controls the motor 422 to operate, so that the sliding seat 423 and the clamp 410 thereon move. When it moves to the position of the cutter 200 to be adjusted, the motor 422 stops, and then controls the double-headed cylinder 411 to work, and the double-headed cylinder 411 contracts, so that the two clamping parts 412 thereon approach each other, thereby clamping the cutter 200. Then, the motor 422 runs again, and the clamp 410 drives the cutter 200 to move to a preset position. Then the motor 422 stops again, and the double-headed cylinder 411 extends, so that the two clamping parts 412 release the cutter 200. In this way, the adjustment of a group of cutters 200 is completed. Subsequently, the same method is used to adjust other cutters 200 to be adjusted.

[0065] It should be noted that a shell 4111 is provided on the outer surface of the double-headed cylinder 411 to protect it.

[0066] It is worth noting that this adjustment method is not only easy to operate, but also has high precision, and can meet the high precision requirements of the printing and packaging industry for the position of the cutter 200. At the same time, the control system can accurately control the motor 422 and the double-headed cylinder 411, and can also ensure the safety and stability of the adjustment process.

[0067] Embodiment 2:

[0068] This embodiment is a further improvement made on the basis of the first embodiment.

[0069] like Figure 1-Figure 2 As shown, in this embodiment, the cutting mechanism further includes:

[0070] The knife groove roller 500 is arranged below the rotating shaft 100 and has a plurality of slots for inserting the blade 230 . The slots are distributed along the axial direction of the knife groove roller 500 . The guide roller 600 is arranged at intervals from the knife groove roller 500 .

[0071] The unrolled material will go around the grooved roller 500 and then go out from the guide roller 600. By setting the grooved roller 500, the grooved roller 500 can provide tension to the material, so that the material is in a traction state, and then it is convenient to be cut by the cutter 200. That is, after the material passes through the grooved roller 500, it is cut by the blade 230, and the cut material is led out by the guide roller 600.

[0072] Embodiment three:

[0073] This embodiment is a further improvement made on the basis of the first and second embodiments.

[0074] like Figure 1-Figure 2As shown, in this embodiment, a swing arm 110 is disposed on one end of the rotary shaft 100 , and the first power device 300 controls the swing arm 110 to swing, thereby realizing the rotation of the rotary shaft 100 .

[0075] Specifically, the first power device 300 includes:

[0076] The piston rod end of the cylinder 310 is rotatably connected to one end of the swing arm 110 away from the rotary shaft 100, and the other end is rotatably mounted on the side plate 1 of the chassis. When the cylinder 310 is extended or retracted, the piston rod thereon can push or pull the end of the swing arm 110 on the rotary shaft 100, thereby causing the swing arm 110 to swing. When the swing arm 110 swings, it can drive the rotary shaft 100 to rotate;

[0077] The limiting portion 320 is used to limit the extension of the cylinder 310. Since the cylinder 310 is used as a power source, the limiting portion 320 is provided to control the extension of the cylinder 310, thereby controlling the downward position of the cutter 200.

[0078] It is worth mentioning that the limiting part 320 is composed of an adjusting shaft 321 and a mounting seat 322 for mounting the adjusting shaft 321. There are two mounting seats 322, both of which are fixed on the side panel 1 of the chassis. The two ends of the adjusting shaft 321 pass through and extend out of the two mounting seats 322, and the adjusting shaft 321 and the mounting seats 322 are rotatably connected by a threaded connection. By rotating the adjusting shaft 321, one end of the adjusting shaft 321 is moved closer to or away from the swing arm 110. By changing the distance between the swing arm 110 and the adjusting shaft 321, the swing amplitude of the swing arm 110 is controlled. When the cylinder 310 pushes the swing arm 110 to rotate and the swing arm 110 is pressed against the end of the adjusting shaft 321, the swing arm 110 can stop rotating. At this time, the working position of the cutter 200 is fixed. It is very convenient and practical to adjust the cutter 200 using this structure.

[0079] Embodiment 4:

[0080] This embodiment is a further improvement made on the basis of any of the above embodiments.

[0081] like Figure 1 , Figure 2 , Figure 4 As shown, in this embodiment, the cutter 200 includes:

[0082] The annular mounting frame 210 is slidably mounted on the rotary shaft 100, and the annular mounting frame 210 is movably mounted or fixedly mounted on the rotary shaft 100 by fastening bolts;

[0083] The knife seat 220 is arranged on the annular mounting frame 210;

[0084] The blade 230 is disposed on the blade holder 220 , and its end extends out of the blade holder 220 . During slitting, the end of the blade 230 is embedded in the notch of the knife groove roller 500 ; during position adjustment, the end of the blade 230 is separated from the notch of the knife groove roller 500 .

[0085] It is worth noting that when adjusting the position of the cutter 200, a worker needs to first loosen the fastening bolts on the annular mounting frame 210, and then start the control system to move the cutter 200. After the positions of all the cutters 200 are adjusted, the fastening bolts on the annular mounting frame 210 are tightened. In order to avoid the friction between the annular mounting frame 210 and the rotating shaft 100 being too small, causing the annular mounting frame 210 to deviate slightly when the worker tightens the bolts, the friction between the annular mounting frame 210 and the rotating shaft 100 can be set to be larger, that is, damping can be set between the two.

[0086] In this embodiment, the outer wall of the annular mounting frame 210 is optimized to be provided with a limiting groove 211; the clamping portion 412 is provided with a limiting protrusion 4121 adapted to the limiting groove 211;

[0087] Among them, when the two ends of the double-headed cylinder 411 retract, the two clamping parts 412 thereon approach each other and the limiting protrusion 4121 is embedded in the limiting groove 211 of the annular mounting frame 210, clamping the annular mounting frame 210; conversely, when the two ends of the double-headed cylinder 411 extend, the two clamping parts 412 thereon move away from each other and loosen the annular mounting frame 210.

[0088] Through the cooperation between the limiting protrusion 4121 and the limiting groove 211 , the clamping portion 412 can clamp the annular mounting frame 210 more firmly, and the annular mounting frame 210 can move more smoothly when moving.

[0089] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
