[0016] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0017] refer to Figures 1 to 4 The present embodiment provides a new type of product cutting adjustable center device, including a top plate 1, a linear guide rail 2 provided at the bottom of the top plate 1, a bracket 3 slidably provided at the bottom of the linear guide rail 2, a screw 4 rotatably provided on the bottom surface of the top plate 1, a screw sleeve 5 provided at the top of the bracket 3 and screwed with the screw 4, a cutter roller 6 rotatably provided in the middle of the bracket 3, a cutter bottom roller 7 rotatably provided at the bottom of the bracket 3, and a cutter cleaning roller 8 provided on the bracket 3 and cooperating with the cutter roller 6.

[0018] It is used for cutting disposable patches on pull-up pants or other sanitary products. Since the center of the equipment process remains unchanged, the corresponding position of the disposable patch will change after the size of the product changes. Therefore, the cutter holder is designed as a mechanism with an adjustable center. When the position of the cutter roller 6 and the bracket 3 needs to be adjusted, the screw 4 is rotated. Since the screw 4 is screwed with the screw sleeve 5 on the top of the bracket 3, when the screw 4 rotates, it drives the bracket 3 to move back and forth on the linear guide rail 2. The screw 4 drives the bracket 3 and the cutter roller 6 on the bracket 3 to move, and the cutting position of the cutter roller 6 can be adjusted, so that products of all sizes can share the same set of cutters. This can save costs and reduce the tediousness of replacing the cutter roller 6 and the bracket 3.

[0019] The bracket 3 includes a first support plate 3a provided on the bottom surface of the top plate 1, a second support plate 3b connected to the first support plate and slidably connected to the linear guide rail 2, and a third support plate 3c rotatably connected to the screw 4. The second support plate is installed on both sides of the first support plate, the third support plate is installed on the front and rear sides of the first support plate, and the rear ends of the first and second support plates are installed on the external wall panel to facilitate the assembly of the bracket 3.

[0020] A handwheel 9 is provided on one side of the screw 4. When the distance between the movable cutter roller 6 and the bracket 3 needs to be adjusted, the handwheel 9 is manually rotated to drive the screw 4 to rotate, thereby adjusting the position of the bracket 3, which is convenient for manual adjustment. The handwheel 9 can also be replaced by a motor or other device with the same function. They are all existing technologies and will not be described in detail here.

[0021] By rotating the hand wheel 9 to rotate the screw 4, the screw sleeve 5 on the screw 4 moves forward and backward along the direction of the screw 4, thereby driving the entire bracket 3 to move forward and backward, achieving the purpose of adjusting the center of the bracket 3.

[0022] An adjustment hole 10 is provided on the top plate 1, and a first adjustment bolt 11 for fixing the support plate of the bracket 3 is screwed into the adjustment hole 10. When the screw 4 drives the bracket 3 to move, the first adjustment bolt 11 is inserted into the adjustment hole 10 on the top plate 1, and then the first adjustment bolt 11 is tightened. The bottom of the first adjustment bolt 11 is stuck in the top of the bracket 3, which can fix the bracket 3 and prevent the bracket 3 from being offset due to mechanical vibration during use.

[0023] The cutter bottom roller 7 is provided with a plurality of suction holes 12, and the bracket 3 is located at the bottom of the cutter bottom roller 7 and is rotatably connected to a pressure-assisting roller 13. The suction holes 12 can transfer the cut material to the pressure-assisting roller 13 for compounding with the fabric, thereby facilitating the transfer of the material.

[0024] A first gear 14 is provided on one side of the cutter roller 6, a second gear 15 meshing with the first gear 14 is provided on one side of the cutter bottom roller 7, and a third gear 16 meshing with the second gear 15 is provided on one side of the auxiliary pressure roller 13. The cutter roller 6, the cutter bottom roller 7 and the auxiliary pressure roller 13 are driven by the first gear 14, the second gear 15 and the third gear 16, and the transmission is more stable and more accurate.

[0025] The cutter cleaning roller 8 is rotatably connected to the cutter cleaning roller 8 on both sides and is provided with a side plate 17, and the side plate 17 is slidably connected to the side away from the cutter cleaning roller 8 and is provided with a second adjusting shaft 18, and the side of the side plate 17 close to the adjusting shaft 18 is provided with a second adjusting bolt 19 for tightening the adjusting shaft 18. The arrangement of the cutter cleaning roller 8, wherein the cutter roller 6 can contact the cutter cleaning roller 8 during the rotation process, is used to clean the blade of the cutter roller 6, and prevent the blade of the cutter roller 6 from not being able to cut the material due to sticking to foreign matter.
