Description

Technical Field

[0001] This utility model belongs to the field of mask indentation technology, specifically relating to an indentation device for mask machines. Background Technology

[0002] Mask-making machines are used to produce masks. When it is necessary to emboss the surface of the mask, an embossing device is installed on the mask-making machine. A embossing device for a mask-making machine, patent application number 202420255196.8, uses a separate design of roller seat, sleeve shaft and embossing sleeve. When changing the embossing roller, only the embossing sleeve needs to be replaced. However, the sleeve shaft and embossing sleeve are separated by lateral pulling. In actual use, due to the limitation of the support structure on both sides of the roller seat, the roller seat and embossing sleeve cannot move laterally by a large margin. Before disassembling the embossing sleeve, the lateral support structure needs to be removed first. Moreover, due to the removal of the support structure, temporary support is also required for the roller seat and sleeve shaft during the disassembly of the embossing sleeve. The workers still need to perform tedious disassembly and assembly work. Utility Model Content

[0018] Please see Figures 1-4The present invention provides the following technical solution: an indentation device for a mask machine, comprising an inner support roller 1 and a connecting shaft 11, a filling strip 12 fixedly connected to the outer wall of the inner support roller 1, an indentation roller sleeve 2 detachably connected to the outer wall of the inner support roller 1, an extension connecting sleeve 21 fixedly connected to both ends of the indentation roller sleeve 2, a relief groove 22 provided at the bottom end of both the indentation roller sleeve 2 and the extension connecting sleeve 21, the relief groove 22 cooperating with the filling strip 12, a support shaft sleeve 3 sleeved on the outer side of the inner support roller 1, a support block 31 fixedly connected to the bottom end of the support shaft sleeve 3, the support block 31 cooperating with the relief groove 22, and a support frame 4 provided at both ends of the inner support roller 1.

[0019] In this implementation scheme: The mask indentation structure is set on the surface of the indentation roller sleeve 2, which is sleeved on the outside of the inner support roller 1. One side of the extension connecting sleeve 21 is fitted with the positioning ring 13 to position the indentation roller sleeve 2. Bolts are threaded into the clearance hole 23 and the fastening bolt hole 14 to fix the extension connecting sleeve 21, thereby fixing the indentation roller sleeve 2. One connecting shaft 11 is connected to a drive device, which drives the inner support roller 1 to rotate, thereby driving the indentation roller sleeve 2 to rotate. The other connecting shaft 11 rotates within the support sleeve 3. When the indentation roller sleeve 2 needs to be replaced, its rotation is adjusted until the position of the clearance groove 22 corresponds to the position of the support block 31. After the workers remove the bolts, the indentation roller sleeve 2 is pulled outward, and the clearance groove 22 makes way for the support block 31, so that the clearance groove 22 can be directly pulled off from the side. The separate design of the inner support roller 1 and the indentation roller sleeve 2 allows the workers to replace only the indentation roller sleeve 2. With the help of the outer extension of the extension connecting sleeve 21 and the cooperation of the filling strip 12 and the clearance groove 22, the indentation roller sleeve 2 can move laterally along the trajectory of the inner support roller 1. In addition, with the matching clearance groove 22 and the support block 31, the workers can easily disassemble and replace the indentation roller sleeve 2 without disassembling the inner support roller 1 and the support frame 4, which greatly reduces the workload and labor intensity of the workers.

[0020] The inner support roller 1 has a positioning ring 13 fixedly connected to its outer wall. The positioning ring 13 corresponds to one of the extended connecting sleeves 21. The positioning ring 13 can be used to position the extended connecting sleeve 21 and thus position the indentation roller sleeve 2. When the extended connecting sleeve 21 and the positioning ring 13 are in contact, the fastening bolt hole 14 corresponds to the clearance hole 23.

[0021] The inner support roller 1 has several fastening bolt holes 14 on its side wall; by setting the fastening bolt holes 14 and the clearance holes 23, bolts can pass through easily to fix the extension connecting sleeve 21, and then fix the indentation roller sleeve 2.

[0022] The side wall of the extension connecting sleeve 21 is provided with a relief hole 23, which corresponds to the position of the fastening bolt hole 14. One of the side walls of the extension connecting sleeve 21 is provided with a slot 24. By providing the relief hole 23, it can cooperate with the fastening bolt hole 14 to facilitate the fixing of the indentation roller sleeve 2. The slot 24 can provide a gripping part to facilitate the application of force to the extension connecting sleeve 21.

[0023] A reinforcing support base 32 is fixedly connected to the bottom end of the support block 31. The projected area of ​​the reinforcing support base 32 is larger than the projected area of ​​the support block 31. The strength of the support structure can be increased by setting the reinforcing support base 32.

[0024] One of the support frames 4 has a fixedly connected limit support plate 41 on its inner wall. The limit support plate 41 is rotatably connected to one of the connecting shafts 11. The position of the limit support plate 41 corresponds to that of the connecting shaft 11 of the drive mechanism, which can more stably limit the position of the connecting shaft 11.

[0025] Another support frame 4 has a support rod 42 fixedly connected to its inner wall, and a reinforcing support seat 32 is fixedly connected to the top of the support rod 42. The support rod 42 can support the reinforcing support seat 32. The position of the support rod 42 corresponds to the position of the limiting support plate 41, so that the two connecting shafts 11 are in a horizontal state.

[0026] The working principle and usage process of this utility model are as follows: The mask indentation structure is set on the surface of the indentation roller sleeve 2, which is sleeved on the outside of the inner support roller 1. The indentation roller sleeve 2 is positioned by the extension connecting sleeve 21 and the positioning ring 13. The extension connecting sleeve 21 is fixed by bolt thread connection in the relief hole 23 and the fastening bolt hole 14, thereby fixing the indentation roller sleeve 2. One of the connecting shafts 11 is connected to the driving device, which drives the inner support roller 1 to rotate, thereby driving the indentation roller sleeve 2 to rotate. The other connecting shaft 11 rotates in the support shaft sleeve 3. When the indentation roller sleeve 2 needs to be replaced, the rotation of the indentation roller sleeve 2 is adjusted until the position of the relief groove 22 corresponds to the position of the support block 31. After the staff removes the bolts, the indentation roller sleeve 2 is pulled outward, and the relief groove 22 makes way for the support block 31. The relief groove 22 is then pulled off directly from the side.
