[0008] Different from the prior art, the technical solution of the present application integrates two sets of elastic band cutting devices, one in front and the other behind, and changes them to be arranged side by side horizontally on the die holder, thereby shortening the length of the production line. In addition, the cutting mechanism is arranged below the anvil roller mechanism, so that the product to be cut does not need to be flipped 180° and can be attached to the cotton core in the next process of the baby pull-up diaper production line, reducing the required product flipping mechanism.

[0009] As an implementation manner of the utility model, the cutting mechanism includes a knife roller and a lower bearing seat assembly, and the knife roller is installed on the side plate through the lower bearing seat assembly; the anvil roller mechanism includes an anvil roller, an anvil roller core shaft and an upper bearing seat assembly.

The axial adjustment mechanism is arranged on both sides of the lower bearing seat assembly, and the horizontal adjustment mechanism is used to drive the lower bearing seat assembly to move horizontally, so that the cutter roller moves horizontally.

[0047] According to some embodiments of this application, please refer to Figures 3 to 7, this embodiment relates to an elastic band cutting device 100, which includes a mold base 1, two elastic band cutting devices 2, and a pressing device 3; the mold base 1 includes side plates 11, a top plate 12, and a bottom plate 13. The top of the side plates 11 is provided with the top plate 12, and the bottom of the side plates 11 is provided with the bottom plate 13; the two elastic band cutting devices 2 are arranged side by side along the horizontal direction X on the mold base 1. The elastic band cutting device 2 includes a cutting mechanism 21, an anvil roller mechanism 22, and a driving mechanism 23. The cutting mechanism 21 is arranged below the anvil roller mechanism 22, and the cutting mechanism 21 and the anvil roller mechanism 22 are respectively connected to the driving mechanism 23; the pressing device 3 is installed on the top plate 12, and the output end of the pressing device 3 is connected to the anvil roller mechanism 22. The pressing device 3 is used to drive the anvil roller mechanism 22 to move along the vertical direction Y.

[0048] The mold base 1 has the structure of an existing mold base 1. The difference is that the upper part of the side plate 11 is provided with the anvil roller mechanism 22, and the lower part is provided with the cutting mechanism 21.

[0049] There are two elastic band cutting devices 2, that is, the two originally independently arranged structures are integrated on one mold base 1, thereby shortening the length of the production line and reducing the space occupied by the production line.

[0050] The pressing device 3 has an existing structure. Its main function is to drive the anvil roller mechanism 22 to approach the knife roller 211 mechanism, so that the anvil roller mechanism 22 contacts the knife roller 211 mechanism, applies working pressure, or drives the anvil roller mechanism 22 to disengage from the knife roller 211 mechanism.

[0051] The technical solution of this application integrates two sets of elastic band cutting devices 2 that were originally arranged one after the other and changes them to be arranged side by side along the horizontal direction X on the mold base 1, thereby shortening the length of the production line. In addition, the cutting mechanism 21 is arranged below the anvil roller mechanism 22, so that the cut product does not need to be flipped 180° and can be attached to the cotton core in the next process of the baby pull-up pants production line, reducing the required product flipping mechanism.

[0052] According to some embodiments of this application, optionally, as Figure 3 and Figure 5 shown, the cutting mechanism 21 includes a knife roller 211 and a lower bearing seat assembly 212. The knife roller 211 is installed on the side plate 11 through the lower bearing seat assembly 212; the anvil roller mechanism 22 includes an anvil roller 221, an anvil roller core shaft, and an upper bearing seat assembly 222. The anvil roller 221 is sleeved on the anvil roller core shaft, and the anvil roller 221 is installed on the side plate 11 through the upper bearing seat assembly 222.

[0053] In this way, the knife roller 211 is installed on the lower part of the side plate 11 through the lower bearing seat assembly 212, and the anvil roller 221 is installed on the upper part of the side plate 11 through the upper bearing seat assembly 222, so that the knife roller 211 is arranged below the anvil roller 221.

[0054] According to some embodiments of the present application, optionally, as Figure 5 shown, the driving mechanism 23 includes a first driving component 231 and a second driving component 232; the first driving component 231 includes a first motor 2311, a first speed reducer 2312 and a first coupling 2313. The first motor 2311 is sequentially connected to the first speed reducer 2312 and the first coupling 2313, and the first coupling 2313 is connected to the anvil roller core shaft; the second driving component 232 includes a second motor 2321, a second speed reducer 2322 and a second coupling 2323. The second motor 2321 is sequentially connected to the second speed reducer 2322 and the second coupling 2323, and the second coupling 2323 is connected to the cutter roller 211.

[0055] In this way, the first motor 2311 is connected to the anvil roller 221 through the first speed reducer 2312 and the first coupling 2313 to realize the rotation of the anvil roller 221; the second motor 2321 is connected to the cutter roller 211 through the second speed reducer 2322 and the second coupling 2323 to realize the rotation of the cutter roller 211. Optionally, the first motor 2311 and the second motor can be stepper motors or servo motors.

[0056] According to some embodiments of the present application, optionally, as Figure 6 shown, the cutter roller 211 includes a roller body 2111, a cutter roller core shaft 2112 and cutter teeth 2113. The roller body 2111 is sleeved on the cutter roller core shaft 2112, the cutter teeth 2113 are symmetrically arranged on the roller body 2111, the cutter roller core shaft 2112 is slidably connected in the lower bearing seat assembly 212, and the cutter roller core shaft 2112 is connected to the first coupling 2313.

[0057] Optionally, the cutter roller 211 further includes heating holes 2114. The heating holes 2114 are opened on the roller body 2111, and heating elements are installed in the heating holes 2114. The cutter teeth 2113 can be heated through the heating elements, which is convenient for the cutter teeth 2113 to cut the material.

[0058] During actual use, first, after the first motor 2311 rotates, it drives the first speed reducer 2312 to rotate, thereby causing the first coupling 2313 to rotate, and then causing the anvil roller core shaft to rotate, so that the anvil roller 221 rotates. Secondly, the pressing device 3 drives the upper bearing seat assembly 222 to move up and down, driving the anvil roller 221 to approach the cutter roller 211, so that the outer circumferential surface of the anvil roller 221 contacts the outer circumferential surface of the cutter roller 211. Finally, the second motor 2321 causes the cutter roller core shaft 2112 to rotate through the second coupling 2323, thereby driving the roller body 2111 to rotate. As the roller body 2111 rotates, the tooth surface of the cutter teeth 2113 contacts the anvil roller 221, and the cutting work of the rubber band begins.

[0059] According to some embodiments of the present application, optionally, the lower bearing seat assembly 212 includes a lower bearing and a lower bearing seat. The lower bearing is sleeved on the cutter roller 211, the lower bearing is installed on the lower bearing seat, and the lower bearing seat is installed at the lower part of the side plate 11; the upper bearing seat assembly 222 includes an upper bearing and an upper bearing seat. The upper bearing is sleeved on the anvil roller 221, the upper bearing is installed on the upper bearing seat, and the upper bearing seat is installed in the slideway at the upper part of the side plate 11.

[0060] Thus, both the lower bearing seat assembly 212 and the upper bearing seat assembly 222 are existing structures, so they are not shown in the figure. The upper bearing seat is installed in the slideway at the upper part of the side plate 11, so that the pressing device 3 drives the upper bearing seat assembly 222 to move up and down along the vertical direction Y in the slideway, driving the anvil roller 221 to approach the cutter roller 211, so that the outer circumferential surface of the anvil roller 221 contacts the outer circumferential surface of the cutter roller 211, applies working pressure or drives the anvil roller 221 to disengage from the cutter roller 211.

[0061] According to some embodiments of the present application, optionally, as Figure 5 shown, the rubber band cutting device 2 further includes a horizontal adjustment mechanism 24. The axial adjustment mechanism is arranged on both sides of the lower bearing seat assembly 212. The horizontal adjustment mechanism 24 is used to drive the lower bearing seat assembly 212 to move along the horizontal direction X, so that the cutter roller 211 moves along the horizontal direction X.

[0062] Thus, the cutter roller 211 can be controlled to move along the horizontal direction X through the horizontal adjustment mechanism 24, so that the cutter roller 211 moves along the horizontal direction X to cut rubber bands of different specifications of products, saving the mold investment cost and the time cost of replacing the mold.

[0063] According to some embodiments of the present application, optionally, as Figure 5 shown, the horizontal adjustment mechanism 24 includes a horizontal adjustment screw 241, an adjustment seat 242 and an adjustment handle 243; the adjustment seat 242 is fixedly installed on the bottom plate 13. A horizontal threaded hole for the horizontal adjustment screw 241 to pass through is provided on the adjustment seat 242. One end of the horizontal adjustment screw 241 is fixedly connected to the lower bearing seat assembly 212, and the other end of the horizontal adjustment screw 241 is connected to the adjustment handle 243. The horizontal adjustment screw 241 is parallel to the horizontal direction X. Rotating the adjustment handle 243 is used to drive the horizontal adjustment screw 241 to rotate, so that the lower bearing seat assembly 212 moves along the horizontal direction X.

[0064] Thus, by driving the rotation of the horizontal adjustment screw 241 through the adjustment handle 243, the lower bearing seat assembly 212 is displaced, and finally the cutter roller 211 installed on the lower bearing seat assembly 212 is driven to move accordingly.

[0065] According to some embodiments of the present application, optionally, as Figure 3As shown, the rubber band cutting device 2 further includes a center distance adjusting mechanism 25. The center distance adjusting mechanism 25 is arranged on the side plate 11 and is used to adjust the center distance between the anvil roller 221 and the cutter roller 211.

[0066] In this way, the center distance adjusting mechanism 25 can adjust the center distance between the anvil roller 221 and the cutter roller 211, so as to avoid the change of the center distance between the anvil roller 221 and the cutter roller 211 due to force, vibration, etc. during the high-speed die-cutting process. In addition, the center distance between the anvil roller 221 and the cutter roller 211 can also be adjusted to cut materials with different thicknesses to meet different processing requirements.

[0067] According to some embodiments of the present application, optionally, as Figure 7 shown, the center distance adjusting mechanism 25 includes an adjusting wedge 251, a center distance adjusting screw 252 and a fixed seat 253. The adjusting wedge 251 is sleeved on the center distance adjusting screw 252, and the fixed seat 253 is sleeved on one end of the center distance adjusting screw 252. The fixed seat 253 is installed on the side plate 11; adjusting the center distance adjusting screw 252 is used to adjust the position of the adjusting wedge 251 to adjust the center distance between the anvil roller 221 and the cutter roller 211.

[0068] In this way, by adjusting the position of the adjusting wedge 251 through the center distance adjusting screw 252, the inclined surface of the adjusting wedge 251 contacts the upper bearing seat assembly 222, and the position of the anvil roller 221 along the vertical direction Y is adjusted through the slope of the inclined surface, and finally the center distance between the anvil roller 221 and the cutter roller 211 is adjusted.
