[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] like Figures 1 to 3 As shown, the embodiment of the present application provides a slitting and winding device, including a frame 1, a slitting assembly 2 and a winding assembly 3. The slitting assembly 2 includes a slitting and transporting roller 21, a slitting and mounting roller 22 and a slitting piece 23. The slitting and transporting roller 21 is rotatably mounted on the frame 1 and rotates driven by the material. The slitting and mounting roller 22 is fixedly mounted on the frame 1. The slitting piece 23 is mounted on the slitting and mounting roller 22 and is used for slitting the material. The winding assembly 3 includes a winding machine 31, which is mounted on the frame 1 and is used for winding the slitting material.

[0033] It should be noted that in this embodiment, the material is set as paper as an example for description. Of course, in other embodiments, according to actual application requirements, the material can also be set as other materials, which is not limited here.

[0034] Specifically, when the device is used, the paper is transported to the winding assembly 3 through the slitting and conveying rollers 21. The staff starts the slitting member 23, which slits the paper passing through the slitting and conveying rollers 21, and the slitting paper is wound up by the winding machine 31.

[0035] The slitting and winding device provided in the present application slits the material through the slitting piece 23 during the winding process, and the winding and slitting are performed synchronously with the cooperation of the slitting transport roller 21 and the winding machine 31. In actual application, there is no need for independent winding and slitting, which helps to improve production efficiency. The slitting installation roller 22 is used to facilitate the installation of the slitting piece 23, which helps to improve the convenience of installation.

[0036] In one embodiment of the present application, see Figures 1 to 3 The slitting member 23 includes a fixed structure 231 and a slitting structure 232 . The fixed structure 231 is slidably mounted on the slitting mounting roller 22 . The slitting structure 232 is mounted on the fixed structure 231 and moves with the fixed structure 231 .

[0037] In this arrangement, since the fixed structure 231 is slidably mounted on the slitting installation roller 22, the fixed structure 231 can move along the axial direction of the slitting installation roller 22, and the slitting piece 23 follows the fixed structure 231 to move along the axial direction of the slitting installation roller 22. In summary, according to the size requirements of material slitting, by changing the position of the slitting piece 23 in the axial direction of the slitting installation roller 22, materials of different sizes can be slid out, thereby meeting different size requirements, which helps to improve the scope of application of the device and also helps to improve the convenience of use of the device.

[0038] In one embodiment of the present application, please refer to Figures 1 to 3 The slitting structure 232 includes a driver 2321 and a cutter 2322. The driver 2321 is installed on the fixed structure 231 and follows the fixed structure 231 to move along the axial direction of the slitting installation roller 22. The cutter 2322 is installed at the output end of the driver 2321 and moves toward or away from the slitting transport roller 21 under the drive of the driver 2321.

[0039] When it is necessary to cut the paper, the staff starts the driver 2321, and the driver 2321 drives the cutter 2322 to move toward the paper on the surface of the cutting and transporting roller 21 until the cutter 2322 contacts the paper. The staff then starts the cutter 2322, and the cutter 2322 can cut the paper passing through the surface of the cutting and transporting roller 21.

[0040] When there is no need to cut the paper, the staff drives the driver 2321, and the driver 2321 drives the cutter 2322 to move back to the cutting and transporting roller 21 until the cutter 2322 is separated from the paper.

[0041] With such a configuration, the cutter 2322 can be used to cut the material passing through the surface of the slitting and transporting roller 21. With the cooperation of the driver 2321, the staff can control whether the cutter 2322 needs to contact the material according to the actual situation, so that the device can be applied to different working conditions, which helps to further improve the application range of the device.

[0042] Optionally, the driver 2321 is configured as a cylinder.

[0043] In one embodiment of the present application, see Figures 1 to 3 The fixing structure 231 is provided with a clamping groove 2311 . The slitting installation roller 22 comprises an installation roller body 221 and a clamping block 222 . The installation roller body 221 is fixedly mounted on the frame 1 . The clamping block 222 is detachably mounted on the installation roller body 221 and clamped in the clamping groove 2311 .

[0044] With such a configuration, the fixing structure 231 and the mounting roller body 221 can be connected by snapping by using the snap-fit ​​groove 2311 and the snap-fit ​​block 222, which helps to improve the structural stability between the fixing structure 231 and the mounting roller body 221. When cutting materials, the cutter 2322 is not easy to fall off, which is convenient for cutting materials and helps to improve the convenience of use. In addition, with the snap-fit ​​groove 2311 and the snap-fit ​​block 222, the fixing structure 231 can move relative to the mounting roller body 221 through the snap-fit ​​groove 2311, which helps to improve the movement stability of the fixing structure 231, and facilitates the adjustment of the axial position of the cutter 2322 on the mounting roller body 221, which helps to improve the convenience of use.

[0045] Optionally, the clamping block 222 is assembled with the mounting roller body 221 by means of bolts.

[0046] With such arrangement, the clamping block 222 and the mounting roller body 221 can be detachably connected by using bolts, and the disassembly and installation are convenient.

[0047] In one embodiment of the present application, see Figures 1 to 3 The fixed structure 231 includes a first fixed seat 2312, a second fixed seat 2313, a third fixed seat 2314, a rotating screw 2315 and a fourth fixed seat 2316. The second fixed seat 2313 and the third fixed seat 2314 are both connected to the first fixed seat 2312 and are arranged at intervals. The rotating screw 2315 passes through the third fixed seat 2314 and is screwed to the third fixed seat 2314. The fourth fixed seat 2316 is rotatably installed on one end of the rotating screw 2315 close to the second fixed seat 2313, and is configured to move toward or away from the second fixed seat 2313 by rotating the rotating screw 2315. The first fixed seat 2312, the second fixed seat 2313 and the fourth fixed seat 2316 enclose a clamping groove 2311.

[0048] When it is necessary to adjust the position of the cutter 2322 in the axial direction of the installation roller body 221, the staff rotates the rotating screw 2315. The rotating screw 2315 is screwed to the third fixing seat 2314 and can rotate relative to the fourth fixing seat 2316. The fourth fixing seat 2316 and the first fixing seat 2312 can form a limit, so that the fourth fixing seat 2316 can only move on the surface of the first fixing seat 2312, that is, the fourth fixing seat 2316 cannot rotate relative to the first fixing seat 2312. By rotating the rotating screw 2315, the staff can drive the fourth fixing seat 2316 to gradually move away from the second fixing seat 2313, so that the distance between the second fixing seat 2313 and the fourth fixing seat 2316 gradually increases, that is, the slot width of the clamping groove 2311 gradually increases, until the fourth fixing seat 2316 and the clamping block 222 are completely separated, and then the position of the cutter 2322 in the axial direction of the installation roller body 221 can be adjusted.

[0049] After adjusting the cutter 2322 to the target position, the staff rotates the screw 2315 in the opposite direction to gradually reduce the distance between the second fixing seat 2313 and the fourth fixing seat 2316, that is, the width of the snap-in groove 2311 gradually decreases, until the fourth fixing seat 2316 and the snap-in block 222 are tightly fitted, so as to fix the cutter 2322 to the snap-in block 222.

[0050] With such a configuration, the fourth fixed block and the clamping block 222 can be separated by using the rotating screw 2315, which is convenient for adjusting the position of the cutter 2322 in the axial direction of the mounting roller body 221, so that materials of different sizes can be cut out, which helps to improve the scope of application of the device. The rotating screw 2315 can make the fourth fixed block abut against the clamping block 222 to prevent the cutter 2322 from moving axially along the mounting roller body 221. During the cutting process, it helps to improve the structural stability between the cutter 2322 and the mounting roller body 221, which is convenient for cutting. The first fixed seat 2312, the second fixed seat 2313 and the fourth fixed seat 2316 can be enclosed to form the clamping groove 2311, so that the cutter 2322 can be installed on the mounting roller body 221. The first fixed seat 2312 is used to facilitate the installation of the driver 2321.

[0051] In one embodiment of the present application, please refer to Figures 1 to 3 The slitting assembly 2 also includes a first slitting tensioning roller 24 and a second slitting tensioning roller 25. The first slitting tensioning roller 24 and the second slitting tensioning roller 25 can be rotatably mounted on the frame 1 and are respectively arranged on both sides of the slitting transport roller 21.

[0052] With such an arrangement, using the first slitting tensioning roller 24 and the second slitting tensioning roller 25, when the material passes through the slitting conveying roller 21, the material can be tensioned from both sides of the slitting conveying roller 21 to prevent the material from folding, making it easier for the cutter 2322 to slitting the material, thereby helping to improve the slitting quality of the device.

[0053] In one embodiment of the present application, see Figures 1 to 3 The slitting assembly 2 also includes a first adjusting seat 26, an adjusting screw 27, a second adjusting seat 28 and an adjusting roller 29. The first adjusting seat 26 is fixedly mounted on the frame 1, the adjusting screw 27 is rotatably mounted on the first adjusting seat 26, the second adjusting seat 28 is rotatably mounted on one end of the adjusting screw 27, and forms a limit with the first adjusting seat 26, and is also configured to move relative to the first adjusting seat 26 by rotating the adjusting screw 27, and the adjusting roller 29 is rotatably mounted on the second adjusting seat 28 and moves with the second adjusting seat 28.

[0054] When the tension of the paper needs to be increased, the staff rotates the adjusting screw 27 to move the second adjusting seat 28 away from the winding assembly 3. It should be noted that the adjusting screw 27 is rotatably mounted on the first adjusting seat 26, so that the adjusting screw 27 can only rotate relative to the first adjusting seat 26, that is, the adjusting screw 27 cannot move relative to the first adjusting seat 26. The second adjusting seat 28 is screwed to the adjusting screw 27 and forms a limit with the first adjusting seat 26, so that the second adjusting seat 28 can only move relative to the first adjusting seat, that is, the second adjusting seat 28 cannot rotate relative to the first adjusting seat 26. Therefore, the staff can drive the second adjusting seat 28 to move away from the winding assembly 3 by rotating the adjusting screw 27 until the paper tension increases to the target value.

[0055] When it is necessary to reduce the tension of the paper, the staff rotates the adjusting screw 27 in the opposite direction to move the second adjusting seat 28 toward the winding assembly 3 until the tension of the paper is reduced to a target value.

[0056] With such a configuration, the adjusting screw 27 is used to adjust the position of the adjusting roller 29, thereby changing the tension of the material, and thus adjusting the tension of the material. In actual application, the staff adjusts the tension of the material according to the actual production needs, which can prevent the material from folding due to insufficient tension, and can also prevent the material from being damaged due to excessive tension, which is convenient for the cutter 2322 to cut the material, and helps to improve the cutting quality of the device.

[0057] In one embodiment of the present application, see Figures 1 to 3The winding assembly 3 also includes a first winding tensioning roller 32, a second winding tensioning roller 33 and a third winding tensioning roller 34. The first winding tensioning roller 32, the second winding tensioning roller 33 and the third winding tensioning roller 34 can all be rotatably installed on the frame 1, and are all located between the slitting assembly 2 and the winding machine 31. The second winding tensioning roller 33 is located between the first winding tensioning roller 32 and the third winding tensioning roller 34.

[0058] With such arrangement, the first winding tensioning roller 32, the second winding tensioning roller 33 and the third winding tensioning roller 34 are used to prevent the material from wrinkling during the winding process, which would cause the winding effect of the device on the material to deteriorate, thereby facilitating the winding of the material.

[0059] In one embodiment of the present application, please refer to Figures 1 to 3 The slitting and winding device also includes a tension detection component 4, which is installed on the frame 1 and is used to detect the tension of the material.

[0060] With such a configuration, the tension detection component 4 can be used to detect the tension of the material. In actual application, the staff can measure the travel speed of the material through the tension detection component 4. By adjusting the tension through an external tension adjustment device, the travel speed of the material can be kept roughly consistent, which is convenient for slitting and winding the material.

[0061] In one embodiment of the present application, see Figures 1 to 3 The tension detection assembly 4 includes a first detection tensioning roller 41, a second detection tensioning roller 42, a third detection tensioning roller 43 and a tension detector 44. The first detection tensioning roller 41, the second detection tensioning roller 42 and the third detection tensioning roller 43 can be rotatably installed on the frame 1 and are used to tension the material. The second detection tensioning roller 42 is located between the first detection tensioning roller 41 and the third detection tensioning roller 43. The tension detector 44 is installed on the frame 1 and is used to detect the tension of the material.

[0062] With such arrangement, the first detection tensioning roller 41, the second detection tensioning roller 42 and the third detection tensioning roller 43 are used to tension the material, making it easier for the tension detector 44 to detect the tension of the material, thereby helping to improve the convenience of use.

[0063] One or more embodiments of the present application are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the present application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of the present application should be included in the protection scope of the present application.
