Description

Technical Field

[0001] This utility model relates to the technical field of sponge cutting equipment, specifically a sponge lace cutting mechanism that facilitates the replacement of cutting tools. Background Technology

[0002] Sponges are porous materials with excellent water absorption, making them suitable for cleaning items. Sponges can be sliced ​​or rolled, and can also be laminated, hot-pressed, or burst-opened according to customer requirements.

[0003] When cutting sponge, lace-like edges, such as wavy edges, may be cut according to customer requirements. Currently, this is generally achieved by using two rollers equipped with lace-cutting tools. However, if the tools need to be replaced between the existing rollers, the rollers need to be removed from the frame, which is inconvenient. On the other hand, the structure of directly mounting the tools on the roller surface with bolts makes it difficult to achieve the required tool precision. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

The side plate 2 is provided with an upper bearing sleeve 3 and a lower bearing sleeve 4. A through groove 5 for replacing the tool is opened between the upper bearing sleeve 3 and the lower bearing sleeve 4 in the side plate 2. A fixing plate 21 is provided at the bottom of the side plate 2 so as to be installed on the frame of the conveyor.

[0024] Both the driving roller 6 and the driven roller 7 are rotatably mounted between two side plates 2. The two ends of the driving roller 6 are respectively connected to the upper bearing sleeve 3, and the two ends of the driven roller 7 are respectively connected to the lower bearing sleeve 4. A tool mounting groove 8 is formed on one side of both the driving roller 6 and the driven roller 7 along their length. A T-shaped slot 9 extends from the inner side of the tool mounting groove 8. The distance from the top of the through groove 5 to the upper bearing sleeve 3 is less than the distance from the T-shaped slot 9 of the driving roller 6 to the upper bearing sleeve 3, and the distance from the bottom of the through groove 5 to the lower bearing sleeve 4 is less than the distance from the T-shaped slot 9 of the driven roller 7 to the lower bearing sleeve 4. These distances ensure that when the tool mounting groove 8 of the driving roller 6 faces downwards and the tool mounting groove 8 of the driven roller 7 faces upwards, the tool can be smoothly pulled out or inserted from the through groove 5, thus facilitating tool replacement. Driven roller 6 and driven roller 7 are respectively provided with drive gear 13 and driven gear 14 at the same end. Driven gear 14 meshes with drive gear 13. Through the cooperation of drive gear 13 and driven gear 14, when drive roller 6 rotates, driven roller 7 rotates in the opposite direction at the same speed as drive roller 6, so that the decorative blades 11 on driven roller 7 and drive roller 6 cooperate to complete the cutting. A motor 15 is provided on the upper surface of top plate 1 at the end away from drive gear 13. Drive sprocket 16 is provided on the output shaft of motor 15. Driven sprocket 17 is provided at the end of drive roller 6 away from drive gear 13. Driven sprocket 17 and drive sprocket 16 are connected by chain 18. Through the cooperation of motor 15, drive sprocket 16, driven sprocket 17 and chain 18, motor 15 drives drive roller 6 to rotate.

[0025] The cutting tool includes a tool holder 10 and a decorative blade 11. The decorative blade 11 is provided on the outer surface of the tool holder 10. A T-shaped extension block 12 is provided on the side of the tool holder 10 away from the decorative blade 11. The tool holder 10 is fitted with the tool mounting groove 8 and fastened with bolts. The tool holder 10 has several connecting holes 19. Several screw holes 20 are provided in the tool mounting groove 8 of both the driving roller 6 and the driven roller 7.

This structure is used to realize the installation and disassembly of the tool holder 10, thereby realizing the replacement of the cutting tool. The T-shaped extension block 12 is fitted with the T-shaped slot 9.

[0026] Installation method and operating principle: First, connect the two ends of the driving roller 6 and driven roller 7 to the upper bearing sleeve 3 and lower bearing sleeve 4 of the side plate 2 respectively. Then connect the two side plates 2 through the top plate 1. Next, install the driving gear 13 and driven sprocket 17 at both ends of the driving roller 6 respectively. Install the driven gear 14 at the end of the driven roller 7 located at the driving gear 13, and make the driven gear 14 mesh with the driving gear 13. At the same time, ensure that the tool mounting slots 8 of the driving roller 6 and driven roller 7 correspond. Install the motor 15 on the upper surface of the top plate 1, and then connect the driving sprocket 16 on the output shaft of the motor 15 to the driven sprocket 17 through the chain 18. Finally, rotate the driving roller 6 and driven roller 7 so that the cutter mounting groove 8 of the driving roller 6 faces downwards, while the cutter mounting groove 8 of the driven roller 7 faces upwards through the gear engagement. Select the appropriate corrugation and the appropriate decorative blade 11 according to the requirements. Insert the two sets of cutters into the through groove 5 of the side plate 2. Insert the T-shaped extension block 12 into the T-shaped slot 9, and insert the cutter holder 10 into the cutter mounting groove 8. After aligning the holes, use bolts to fix the cutter holder 10, completing the connection between the cutter and the driving roller 6 and driven roller 7, thus completing the installation. Note that the decorative blades 11 installed on the driving roller 6 and driven roller 7 are symmetrical. When changing the cutter, turn the cutter on the driving roller 6 downwards, and the cutter on the driven roller 7 upwards. Loosen the bolts and pull the cutter out from the through groove 5. This utility model has a reasonable structure. The side plate 2 is provided with a through groove 5 between the upper bearing sleeve 3 and the lower bearing sleeve 4. The active roller 6 and the driven roller 7 are provided with a tool mounting groove 8 along the length direction on one side. The inner side of the tool mounting groove 8 is also provided with a T-shaped slot 9. The tool is inserted into the tool mounting groove 8 through the tool holder 10 and fastened with bolts. The T-shaped extension block 12 is inserted into the T-shaped slot 9. This structure allows the tool to be replaced through the through groove 5 of the side plate 2 without disassembling the active roller 6 or the driven roller 7, which greatly improves convenience. On the other hand, the tool is more stable and accurate than the connection structure in which the tool is directly fastened to the roller surface by bolts through the cooperation of the T-shaped extension block 12.
