DETAILED DESCRIPTION

[0021] Example One: Please refer to Figures 1 to 5 The embodiment of the present application provides a PVB diaphragm embossing roller demolding structure, mainly used for avoiding the adhesion of the diaphragm 12 and the printing roller 10, and applicable to different anilox rollers 2. The demolding structure comprises a material box 1, an anilox roller 2 and a transfer roller 3. The material box 1 is provided with a cavity for accommodating the anilox roller 2. A liquid demolding agent dedicated to the diaphragm 12 is arranged in the cavity during use. The liquid demolding agent can prevent the diaphragm 12 from adhering to metal.

[0022] In the above structure, the material box 1 is fixedly installed on the machine tool 9. The machine tool 9 is further provided with the printing roller 10 and the embossing roller 11 corresponding to each other. The diaphragm 12 is processed between the printing roller 10 and the embossing roller 11. The transfer roller 3 is movably attached to the printing roller 10. The demolding structure is used to prevent the diaphragm 12 from adhering to the printing roller 10.

[0023] In the above structure, the surface of the anilox roller 2 is sprayed with tungsten carbide. The surface is provided with engraved lines which can store the demolding agent. During use, the anilox roller 2 is partially immersed in the demolding agent in the material box 1. When the anilox roller 2 rotates, the demolding agent in the material box 1 is brought out and coated on the printing roller 10 by the transfer roller 3. In this way, the surface of the printing roller 10 is uniformly coated with the demolding agent, so that the diaphragm 12 will not adhere to the printing roller 10 when passing through.

[0024] In the embodiment, the material box 1 is further connected to a feeding module (not shown in the figure) during use. The feeding module is used to stably feed the demolding agent into the material box 1. The feeding module, the printing roller 10, the embossing roller 11, the material box 1, the anilox roller 2, the transfer roller 3 and the demolding agent are all existing mature technologies, and will not be described in detail here.

[0025] Further, the material box 1 is provided with a driving assembly 4 for driving the rotation of the anilox roller 2 and the transfer roller 3, the corresponding arrangement of the anilox roller 2 and the transfer roller 3 can be realized through the driving assembly 4, and the corresponding replacement of the anilox roller 2 and the transfer roller 3 is facilitated. Meanwhile, the material box 1 is also provided with an adjusting assembly 5 for adjusting the position of the transfer roller 3, the transfer roller 3 can always be kept in an active and close-fitting state with the anilox roller 2 and the printing roller 10 through the adjusting assembly 5, thereby ensuring the transfer of the release agent to the printing roller 10, and finally avoiding the adhesion of the film 12 to the printing roller 10.

[0026] With reference to Figures 2 to 5 In the embodiment, preferably, the driving assembly 4 includes two motors 401, the first motor 401 corresponds to the anilox roller 2 and is fixedly connected with the material box 1, the second motor 401 corresponds to the transfer roller 3 and is driven by the adjusting assembly 5, the output shafts of the two motors 401 are both fixedly installed with sleeves 402, the inside of the sleeve 402 is coaxially and drivingly provided with a support rod 403, the end of the support rod 403 away from the sleeve 402 is clamped with the anilox roller 2 / transfer roller 3, for driving the anilox roller 2 / transfer roller 3 to rotate synchronously.

[0027] In the above structure, the sleeve 402 and the support rod 403 are in a key shaft type assembly, that is, the sleeve 402 can drive the support rod 403 to rotate synchronously, and the support rod 403 can reciprocate along the sleeve 402. Correspondingly, the outer surface of the support rod 403 is provided with a horizontal groove 405, and the inside of the sleeve 402, the end of the anilox roller 2 and the end of the transfer roller 3 are all provided with an embedding block 6 corresponding to the horizontal groove 405, the embedding block 6 is clamped in the horizontal groove 405 to form synchronous rotation with the support rod 403.

[0028] Among them, in order to improve the supporting effect of the anilox roller 2 and the transfer roller 3, the same sleeve 402 and support rod 403 can also be installed at the other end of the anilox roller 2 and the transfer roller 3. It can be understood that the difference between the left and right sides of the anilox roller 2 and the transfer roller 3 is that two motors 401 are also provided on one side.

[0029] Meanwhile, the inside of the sleeve 402 is also fixedly installed with a first spring 404 abutting against the end of the support rod 403, the first spring 404 makes the support rod 403 have a tendency to move away from the sleeve 402, thereby making the support rod 403 close to the anilox roller 2 / transfer roller 3, thereby clamping the anilox roller 2 / transfer roller 3 in the middle and forming synchronous rotation through the embedding block 6 and the support rod 403. Correspondingly, the first spring 404 can also be arranged only in the sleeve 402 on one side, at this time the anilox roller 2 / transfer roller 3 can be pushed to move to the other side through the support rod 403 on this side, and the same limiting effect on the anilox roller 2 / transfer roller 3 can also be realized.

[0030] With reference to Figures 2 to 4In the embodiment, preferably, the adjusting assembly 5 comprises two sets of telescopic rods, and each telescopic rod comprises a base 501, the inside of the base 501 is elastically connected with a sliding rod 502 by a second spring 503, the first base 501 is fixedly connected with the material box 1, the second base 501 is fixedly connected with the sliding rod 502 on the first base 501, and the sliding rod 502 on the second base 501 is movably sleeved on the outer surface of the sleeve 402 corresponding to the transfer roller 3, and the sliding rod 502 is fixedly connected with the second motor 401, and at this time, the position of the sleeve 402 corresponding to the transfer roller 3 is limited by the sliding rod 502 on the second base 501.

[0031] In the above structure, the two sets of telescopic rods are in an L-shaped design and are in a state of being rotated 90 degrees clockwise in the L shape, wherein the second base 501 is horizontally arranged, and the first base 501 is vertically arranged. At the same time, the second spring 503 makes the sliding rod 502 have a tendency to shrink into the corresponding base 501.

[0032] Correspondingly, when the transfer roller 3 is installed on the support rod 403, because the sliding rod 502 on the second base 501 has a tendency to approach the second base 501, the sliding rod 502 on the first base 501 has a tendency to approach the first base 501, and finally the transfer roller 3 can be made to approach the direction of the anilox roller 2 downward, and the transfer roller 3 can also be automatically formed to be attached to the printing roller 10 in the process of descending. Thus, under the premise of realizing the rapid disassembly of the transfer roller 3, the demolding structure in the embodiment can also be suitable for different diameters of the transfer roller 3, thereby greatly improving the overall application range.

[0033] In use, first, the support rod 403 is retracted in the direction of the sleeve 402, and the anilox roller 2 / transfer roller 3 is moved to correspond to the support rod 403 in turn, then the support rod 403 is loosened, and the support rod 403 and the anilox roller 2 / transfer roller 3 are automatically clamped by the first spring 404, so as to realize the synchronous rotation of the support rod 403 and the anilox roller 2 / transfer roller 3, and the transfer roller 3 is automatically attached to the printing roller 10 and the anilox roller 2 by the sliding rod 502, the second spring 503 and the base 501. When the film sheet 12 passes between the printing roller 10 and the embossing roller 11, the processing is completed, and at this time, the anilox roller 2 and the transfer roller 3 are driven to rotate by the start of the two motors 401, the demolding agent in the material box 1 is evenly coated on the printing roller 10 by the transfer roller 3, and the adhesion of the film sheet 12 and the printing roller 10 can be effectively avoided.

[0034] In summary, through the coordination of the support rod 403, transfer roller 3, base 501, and slide rod 502, the release agent can be evenly applied to the embossing roller 10 to prevent adhesion of the film 12 to the embossing roller 10, thereby ensuring reliable and stable embossing quality of the film 12. Furthermore, the anilox roller 2 and transfer roller 3 can be quickly assembled and disassembled, and the anilox roller 2 and transfer roller 3 can be adapted to different diameters. This ensures that the transfer roller 3 is automatically and effectively bonded to the embossing roller 10 and the anilox roller 2, reducing the overall labor burden and increasing work efficiency, thereby enhancing practicality.

[0035] Example 2: See also Figures 1 to 8 Based on the first embodiment, considering the amount of release agent used, in actual production, a scraper module 7 that is movably attached to the anilox roller 2 is usually installed on the anilox roller 2. Furthermore, when replacing anilox rollers 2 with different diameters, the position of the scraper module 7 must be adjusted accordingly to ensure proper attachment of the scraper module 7 to the anilox roller 2. This increases the operator's burden and reduces work efficiency.

[0036] To this end, a scraper module 7 corresponding to the anilox roller 2 is first provided on the material box 1, and a synchronization component 8 for supporting the scraper module 7 is provided between the two slide bars 502. Through the synchronization component 8 and the adjustment component 5, when the anilox roller 2 of different diameter sizes is replaced, the transfer roller 3 can automatically form a fit with the anilox roller 2, and the scraper module 7 can also automatically form a fit with the anilox roller 2.

[0037] Reference Figures 6 to 8 In this embodiment, preferably, the synchronization assembly 8 includes a gear 801 rotatably mounted on the vertical slide 502 and a partition 802 slidably mounted on the vertical slide 502. The scraper module 7 is disposed on the partition 802 and driven by the partition 802, and the partition 802 and the vertical slide 502 are in horizontal sliding engagement. Correspondingly, the vertical slide 502 is provided with a slot 504 for the partition 802 to slide. Racks 803 meshing with the gear 801 are fixedly mounted on both the partition 802 and the horizontal slide 502. The two racks 803 are symmetrically staggered around the gear 801, thereby causing the two racks 803 to move in opposite directions, thereby causing the horizontal slide 502 and the partition 802 to move in opposite directions.

[0038] In the above structure, the center position of the scraper module 7 and the center position of the support rod 403 on the transfer roller 3 are arranged symmetrically left and right based on the gear 801, and at this time the scraper module 7 and the anilox roller 2 are just in the state of being in close contact. Thus, when the support rod 403 drives the transfer roller 3 to move a corresponding distance, the spacer plate 802 and the scraper module 7 can be driven to move the same corresponding distance in the opposite direction through the rack 803, and then when the anilox roller 2 of different diameter sizes is replaced, the transfer roller 3 can be in close contact with the anilox roller 2 through the slide rod 502 and the base 501, and the scraper module 7 can also be moved to be in close contact with the anilox roller 2 correspondingly.

[0039] In use, through the structures of the transfer roller 3, the base 501 and the slide rod 502, etc., the film 12 can be prevented from being adhered to the printing roller 10 and can be suitable for anilox rollers 2 and transfer rollers 3 of different diameter sizes, and the working process and effects of this part are the same as those in Embodiment One, which will not be repeated here. The difference is that when the anilox roller 2 of different diameter sizes is replaced, the transfer roller 3 can be automatically in close contact with the anilox roller 2 through the slide rod 502, the second spring 503 and the base 501, and when the transfer roller 3 moves, the first rack 803 can be driven to move through the slide rod 502 in the horizontal state, the first rack 803 can drive the spacer plate 802 and the scraper module 7 to move in the opposite direction along the horizontal direction through the gear 801 and the second rack 803, and the slide rod 502 in the vertical state can drive the spacer plate 802 and the scraper module 7 to move in the vertical direction synchronously, and then the scraper module 7 can also be automatically in close contact with the anilox roller 2.

[0040] Compared with Embodiment One, through the cooperation of the spacer plate 802, the slide rod 502, the scraper module 7 and the rack 803, etc., when the anilox roller 2 of different diameter sizes is replaced, the transfer roller 3 can be automatically in close contact with it, and through the movement of the transfer roller 3, the scraper module 7 can also be automatically in close contact with the anilox roller 2, and then it is not necessary to manually adjust the position of the scraper module 7, which can effectively reduce the labor burden and improve the work efficiency. The overall scheme is combined with the movement of the transfer roller 3, the scraper module 7 is correspondingly moved to be in close contact with the anilox roller 2 through the movement of the transfer roller 3, the movement of the transfer roller 3 achieves the purpose of multifunction, and through the effective close contact of the scraper module 7 and the anilox roller 2, the effective use of the release agent can be realized, the use amount of the release agent can be reduced, and the applicability is stronger.

[0041] As a further improvement of the present embodiment: refer to Figure 9 and Figure 10 An annular groove 406 is formed in the outer surface of the support rod 403 on one side, which is connected with the transverse groove 405, the insert block 6 in the sleeve 402 is arranged in a state of not being in contact with the bottom wall of the sleeve 402, and the length dimension of the annular groove 406 along the axial direction of the support rod 403 is greater than or equal to the length dimension of the insert block 6 in the sleeve 402 along the axial direction of the support rod 403.

[0042] When the side support rod 403 is retracted into the sleeve 402, if the block 6 corresponds to the annular groove 406, the sleeve 402 can also rotate the support rod 403 to make the block 6 enter the annular groove 406, at this time, the support rod 403 can be limited relative to the sleeve 402, and the support rod 403 can also be separated from the anilox roller 2 / transfer roller 3, and the other side support rod 403 has not been separated from the anilox roller 2 / transfer roller 3, so that the anilox roller 2 / transfer roller 3 can be supported, and the anilox roller 2 / transfer roller 3 will not directly fall off after the support rod 403 with the annular groove 406 is separated from the anilox roller 2 / transfer roller 3.

[0043] The overall combination can further facilitate the quick disassembly and assembly of the anilox roller 2 / transfer roller 3, and a single person can quickly realize the overall disassembly and assembly steps, which can further improve the overall economic benefit and meet more needs in actual use.
