Description

Technical Field

[0001] The utility model relates to the technical field of disposable hygiene product production equipment, in particular to a novel short-cutting device. Background Art

[0002] At present, in the production process of baby pull-up pants, the transmission mechanism used by the short-cutting device for the conductive layer material has a 1:1 structure. The size of the diameter of the cutter roller of the short-cutting device for the conductive layer material is closely related to the size of the pull-up pants. In order to save costs, often a production line is compatible with making many sizes of pull-up pants. With the improvement of living standards, the required size of pull-up pants is getting larger and larger. This leads to the need for the short-cutting device for the conductive layer material to be re-sized when the production line needs to be compatible with a wider range of products of multiple sizes. If the transmission mechanism is still designed according to the 1:1 structure, the entire short-cutting device for the conductive layer material needs to be replaced, resulting in a high cost. Content of the Utility Model

[0003] Therefore, in view of the above problems, the utility model provides a novel short-cutting device, which mainly solves the problems in the prior art that the size compatibility of the short-cutting device is poor and the whole set needs to be replaced, resulting in high costs.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] A novel short-cutting device, comprising a frame, a support plate, side plates, a cutter roller, a bottom roller, a first bearing, a second bearing, a transmission mechanism and a driving mechanism. The support plate is fixedly arranged on the frame, the side plates are fixedly arranged on the support plate, the axial two ends of the cutter roller are rotatably arranged on the side plates through the first bearing, the cutter roller includes a cutter, and the cutter has a cutter working surface. The axial two ends of the bottom roller are rotatably arranged on the side plates through the second bearing and are distributed on the periphery of the cutter roller. The bottom roller has a bottom roller working surface that cooperates with the cutter. The linear velocity of the cutter working surface is equal to the linear velocity of the bottom roller working surface. The driving mechanism is connected to the cutter roller and the bottom roller through the transmission mechanism. The transmission mechanism includes a first synchronous pulley, a second synchronous pulley, a first tensioning pulley, a second tensioning pulley and a transmission belt. The first synchronous pulley is arranged on the cutter roller, the second synchronous pulley is arranged on the bottom roller, the first tensioning pulley and the second tensioning pulley are arranged on the side plates and are distributed on both sides of the cutter roller. The transmission belt is sequentially wound around the first synchronous pulley, the first tensioning pulley, the second synchronous pulley and the second tensioning pulley.

[0006] Further, the bottom roller includes an intermediate shaft, a roller body arranged on the intermediate shaft and at least two anvil assemblies. Each of the anvil assemblies is evenly distributed around the roller body in a circumferential manner. The anvil assemblies cooperate with the cutter to realize the cutting of the material.

[0007] Further, the cutting board assembly includes a first clamping block, a second clamping block and a cutting board. The first clamping block and the second clamping block are distributed on both sides of the cutting board for fixing the cutting board. The working surface of the bottom roller is distributed on the cutting board. Both the first clamping block and the second clamping block have arc surfaces, and the working surface of the bottom roller is higher than the arc surfaces.

[0008] Further, an installation groove for installing the cutting board assembly is concavely provided on the roller body. The installation groove includes a first groove for installing the first clamping block, a second groove for installing the second clamping block and a third groove for installing the cutting board. The first groove, the second groove and the third groove communicate with each other. One side surface of the second groove far away from the third groove is inclinedly distributed, and an adjusting bolt is threadedly connected to the bottom surface of the third groove.

[0009] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows: for this new type of short cutting device, the driving mechanism synchronously drives the cutter roller and the bottom roller to rotate through the transmission mechanism, and cuts the material passing between the two through the cutter roller and the bottom roller. Moreover, through the cooperation of the first synchronous belt pulley, the second synchronous belt pulley, the first tensioning pulley, the second tensioning pulley and the transmission belt, the synchronous transmission of the cutter roller and the bottom roller is realized. Thus, when the diameter size of the cutter roller changes, the line speed of the cutter working surface can be configured to be equal to the line speed of the bottom roller working surface by replacing the models of the first synchronous belt pulley 81 and the second synchronous belt pulley, which is convenient for a single production line to compatibly produce products of multiple yardages and reduces the changeover cost.

[0014] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] An embodiment of the present utility model is as follows:

[0016] Refer to Figures 1 to 4As shown in the figure, a new type of short-cutting device includes a frame 1, a support plate 2, side plates 3, a cutter roller 4, a bottom roller 5, a first bearing 6, a second bearing 7, a transmission mechanism 8, and a driving mechanism (not shown in the figure). The support plate 2 is fixedly arranged on the frame 1, the side plates 3 are fixedly arranged on the support plate 2, the axial two ends of the cutter roller 4 are rotatably arranged on the side plates 3 through the first bearing 6. The cutter roller 4 includes a cutter 41 which has a cutter working surface 42. The axial two ends of the bottom roller 5 are rotatably arranged on the side plates 3 through the second bearing 7 and are distributed on the circumferential side of the cutter roller 4. The bottom roller 5 has a bottom roller working surface 51 which cooperates with the cutter 41. The linear velocity of the cutter working surface 42 is equal to the linear velocity of the bottom roller working surface 51. The driving mechanism is connected to the cutter roller 4 and the bottom roller 5 through the transmission mechanism 8. The transmission mechanism 8 includes a first synchronous pulley 81, a second synchronous pulley 82, a first tensioning pulley 83, a second tensioning pulley 84, and a transmission belt 85. The first synchronous pulley 81 is arranged on the cutter roller 4, the second synchronous pulley 82 is arranged on the bottom roller 5, the first tensioning pulley 83 and the second tensioning pulley 84 are arranged on the side plates 3 and are distributed on both sides of the cutter roller 4. The transmission belt 85 is wound around the first synchronous pulley 81, the first tensioning pulley 83, the second synchronous pulley 82, and the second tensioning pulley 84 in sequence.

[0017] For this new type of short-cutting device, the driving mechanism drives the cutter roller 4 and the bottom roller 5 to rotate synchronously through the transmission mechanism 8, and cuts the material passing between the two through the cutter roller 4 and the bottom roller 5. Through the cooperation of the first synchronous pulley 81, the second synchronous pulley 82, the first tensioning pulley 83, the second tensioning pulley 84, and the transmission belt 85, the synchronous transmission of the cutter roller 4 and the bottom roller 5 is realized. Thus, when the diameter size of the cutter roller 4 changes, the linear velocity of the cutter working surface 42 can be configured to be equal to the linear velocity of the bottom roller working surface 51 by replacing the models of the first synchronous pulley 81 and the second synchronous pulley 82, which is convenient for the same production line to be compatible with the production of products in multiple yardages and reduces the cost of changing numbers.

[0018] Specifically, the bottom roller 5 includes an intermediate shaft 52, a roller body 53 provided on the intermediate shaft 52, and two anvil assemblies 54. Each of the anvil assemblies 54 is evenly distributed around the roller body 53. The anvil assembly 54 cooperates with the cutting knife 41 to achieve the cutting of materials. The anvil assembly 54 includes a first clamping block 541, a second clamping block 542, and an anvil 543. The first clamping block 541 and the second clamping block 542 are distributed on both sides of the anvil 543 for fixing the anvil 543. The working surface 51 of the bottom roller is distributed on the anvil 543. Both the first clamping block 541 and the second clamping block 542 have arc surfaces 55, and the working surface 51 of the bottom roller is higher than the arc surface 55. An installation groove 10 for installing the anvil assembly 54 is recessed on the roller body 53. The installation groove 10 includes a first groove 101 for installing the first clamping block 541, a second groove 102 for installing the second clamping block 542, and a third groove 103 for installing the anvil 543. The first groove 101, the second groove 102, and the third groove 103 are communicated. One side surface of the second groove 102 far from the third groove 103 is inclinedly distributed. The bottom surface of the third groove 103 is threadedly connected with an adjusting bolt 104.

[0019] During use, the cutting knife 41 of the knife roller 4 cooperates with the anvil 543 on the anvil assembly 54 to achieve the cutting of materials. The anvil is fixed by the first clamping block 541 being clamped in the first groove 101 and the second clamping block 542 being clamped in the second groove 102. Moreover, one side surface of the second groove 102 is inclinedly distributed, so that the second clamping block 542 can clamp the anvil 543 better after being embedded, thereby making the installation firmness of the anvil 543 good. At the same time, by adjusting the height of the adjusting bolt 104 on the bottom surface of the third groove 103, the height of the working surface 51 of the bottom roller of the anvil 543 is adjustable, so as to be applicable to the production of products of multiple yardages and reduce the replacement frequency of the anvil 543.
