Specific implementation

[0029] In order to further illustrate the technical means and effects adopted by the application to achieve the predetermined application purpose, the specific implementation, structure, features and effects according to the application are described in detail as follows by combining with the drawings and preferred embodiments.

[0030] Please refer to Figures 1-6The embodiment provides a wide-width gilding film winding auxiliary supporting mechanism, which comprises a rack 1, a winding assembly 2 and a supporting assembly 3. The winding assembly 2 comprises an air expansion shaft 201 and a rotating motor 202. One end of the air expansion shaft 201 is horizontally connected with the rack 1, and the rotating motor 202 is arranged on the rack 1. The output end of the rotating motor 202 is coaxially connected with the end of the air expansion shaft 201 close to the rack 1, and the rotating motor 202 is used for driving the air expansion shaft 201 to rotate. It should be noted that the air expansion shaft 201 is used for being attached to the inner side wall of the winding drum of the winding material, and the winding drum of the winding material is rotated under the control of the rotating motor 202, so that the gilding film is wound. However, the air expansion shaft 201 is stressed at one end and suspended at the other end, so that the air expansion shaft 201 is unbalanced at both ends, and the air expansion shaft 201 is offset during material winding. Therefore, the winding assembly 2 further comprises a supporting bearing 203 coaxially connected with the other end of the air expansion shaft 201. The supporting assembly 3 comprises a supporting rod 301 which is located directly below the supporting bearing 203 in a lifting manner. The supporting rod 301 is locked or unlocked with the supporting bearing 203 through lifting, so as to realize the supporting effect of the other end of the air expansion shaft 201, so that the air expansion shaft 201 is balanced at both ends. The existing winding device of the digital printing machine adopts the air expansion shaft 201 as the power source of the winding device. Since one end of the air expansion shaft 201 is arranged on the rack 1 and the other end is suspended, the air expansion shaft 201 is unbalanced at both ends when the length of the air expansion shaft 201 is long, and the air expansion shaft 201 is offset during material winding.

[0031] The above scheme only solves the supporting effect of the supporting rod 301 on the other end of the air expansion shaft 201 during the work of the air expansion shaft 201. However, when the winding material after winding is removed from the air expansion shaft 201 and a new winding drum is replaced, the supporting rod 301 needs to unlock the supporting effect on one end of the air expansion shaft 201. Since the weight of the winding material after winding is too heavy, the air expansion shaft 201 may be inclined due to the weight of the winding material when the supporting rod 301 unlocks the supporting effect on one end of the air expansion shaft 201. Therefore, the present scheme also needs to solve the problem of how to keep the air expansion shaft 201 balanced at both ends when the winding material after winding is removed from the air expansion shaft 201 and a new winding drum is replaced.

[0032] Based on this, the scheme also includes a material collecting assembly 4, which includes a hollow main rod 401, a material collecting cylinder 402 and a connecting rod 403, the material collecting cylinder 402 and the connecting rod 403 are coaxially arranged in the main rod 401, the material collecting assembly 2 also includes a hollow communication rod 204, one end of the communication rod 204 is coaxially arranged at the end of the gas expansion shaft 201 away from the rack 1, the main rod 401 is coaxially connected with the gas expansion shaft 201, and the main rod 401 is arranged beside the other end of the communication rod 204, the material collecting cylinder 402 is connected with the connecting rod 403, the connecting rod 403 is controlled to slide along the arrangement direction of the main rod 401 to realize the locking or unlocking of the mutual cooperation relationship between the connecting rod 403 and the communication rod 204, the scheme is provided with the material collecting cylinder 402 and the connecting rod 403, when the output end of the material collecting cylinder 402 is elongated, the connecting rod 403 extends out of the main rod 401, and one end of the connecting rod 403 is coaxially inserted into the communication rod 204, the connecting rod 403 of the scheme is a solid cylinder, which has strong bending resistance and deformation resistance, so that when one end of the connecting rod 403 is coaxially inserted into the communication rod 204, the bending resistance and deformation resistance of the gas expansion shaft 201 near the end of the communication rod 204 are improved, and the winding material on the gas expansion shaft 201 can be transmitted to the main rod 401 through the connecting rod 403 to realize the structure effect that the winding material after winding is removed out of the gas expansion shaft 201.

[0033] Specifically, the supporting assembly 3 of the scheme also includes a supporting cylinder 302, which is arranged on the rack 1, the output end of the supporting cylinder 302 is connected with the supporting rod 301, the extension axis direction of the output end of the supporting cylinder 302 is perpendicular to the arrangement axis direction of the gas expansion shaft 201, with the lifting of the output end of the supporting cylinder 302, the supporting rod 301 connected therewith is controlled to move along the extension direction of the output end of the supporting cylinder 302 to realize the structure effect that the supporting rod 301 is locked or unlocked from the abutting cooperation with the supporting bearing 203.

[0034] Specifically, the supporting assembly 3 of the scheme also includes a supporting module 303, which is arranged in the communication rod 204, the supporting module 303 is communicatively connected with the supporting cylinder 302, the connecting rod 403 can lock or unlock the pressing cooperation relationship with the supporting module 303, it should be noted that in the scheme, when the connecting rod 403 presses the supporting module 303, the supporting module 303 controls the output end of the supporting cylinder 302 to contract, so that the supporting rod 301 is unlocked from the abutting cooperation with the supporting bearing 203, and then the supporting effect of the supporting rod 301 on the gas expansion shaft 201 is removed; after the connecting rod 403 is no longer pressed on the supporting module 303, the supporting module 303 controls the output end of the supporting cylinder 302 to extend until the supporting rod 301 is locked from the abutting cooperation with the supporting bearing 203, and then the supporting effect of the supporting rod 301 on the gas expansion shaft 201 is re-implemented.

[0035] In order to enhance the support effect of the connecting rod 403 on the communicating rod 204, and facilitate the extension of the connecting rod 403 into the communicating rod 204, the material collecting assembly 4 further comprises a plurality of telescopic blocks 404 and a plurality of telescopic springs 405, the diameter of the connecting rod 403 is smaller than the inner diameter of the communicating rod 204, the connecting rod 403 is provided with a plurality of telescopic grooves 4031, the plurality of telescopic grooves 4031 are arranged on the outer side wall of the connecting rod 403 along the central axis of the connecting rod 403 at equal angles, the plurality of telescopic blocks 404, the plurality of telescopic springs 405 and the plurality of telescopic grooves 4031 are matched one by one, any telescopic block 404 and any telescopic spring 405 are arranged in the corresponding telescopic groove 4031, the telescopic block 404 is arranged in the corresponding telescopic groove 4031 in a lifting manner, the two ends of the telescopic spring 405 are connected with the telescopic block 404 and the telescopic groove 4031 respectively, the top surface of the telescopic block 404 abuts and matches with the inner side wall of the communicating rod 204, through such arrangement, firstly, since the diameter of the connecting rod 403 is smaller than the inner diameter of the communicating rod 204, it is ensured that the connecting rod 403 can smoothly extend into the communicating rod 204; in addition, since the diameter of the connecting rod 403 is smaller than the inner diameter of the communicating rod 204, after the connecting rod 403 extends into the communicating rod 204, the bending resistance and the deformation resistance of the communicating rod 204 cannot be improved, therefore, by arranging the telescopic block 404 and the telescopic spring 405, when the telescopic spring 405 extends into the communicating rod 204, the telescopic spring 405 is in a compressed state, the telescopic spring 405 drives the telescopic block 404 to move towards the inner wall of the communicating rod 204, so that the surface of the telescopic block 404 abuts with the inner wall of the communicating rod 204, so as to ensure that after the connecting rod 403 extends into the communicating rod 204, the bending resistance and the deformation resistance of the communicating rod 204 can be improved.

[0036] In order to further enhance the support effect of the connecting rod 403 on the communicating rod 204, and facilitate the extension of the connecting rod 403 into the communicating rod 204, the end of the telescopic block 404 close to the connecting rod 403 is arranged in an inclined manner, the thickness of the top of the telescopic block 404 gradually decreases along the axis direction close to the connecting rod 403, and the distance between the lowest point of the inclined end surface of the telescopic block 404 and the central axis of the main rod 401 is equal to or less than the radius of the communicating rod 204.

[0037] Since the support assembly 3 described above is not the existing common auxiliary support structure of the gas expansion shaft 201, the corresponding removal mode of the completed winding material also needs to be changed to match the support assembly 3 of the present scheme. The present scheme also includes a pushing assembly 5, which includes a pushing plate 501 and a pushing cylinder 502. The pushing cylinder 502 is arranged on the rack 1, and the pushing plate 501 is slidingly arranged on the gas expansion shaft 201 along the central axis direction of the gas expansion shaft 201. The output end of the pushing cylinder 502 is connected with the pushing plate 501. By arranging the pushing cylinder 502, the output end of the pushing cylinder 502 drives the pushing plate 501 to slide on the gas expansion shaft 201 along the central axis direction of the gas expansion shaft 201 when working, thereby realizing pushing the completed winding material to the main rod 401.

[0038] Further, the pushing assembly 5 of the present scheme also includes a pushing module 503, and the support assembly 3 also includes a support spring 304 arranged in the communication rod 204. The two ends of the support spring 304 are respectively connected with the gas expansion shaft 201 and the support module 303. The pushing module 503 is arranged in the communication rod 204 and is arranged on one end face of the gas expansion shaft 201. The pushing module 503 is in communication connection with the pushing cylinder 502. Through such arrangement, the distance between the support module 303 and the connecting rod 403 is less than the distance between the pushing module 503 and the connecting rod 403. Therefore, when the connecting rod 403 extends into the communication rod 204, the connecting rod 403 first realizes pressing cooperation with the support module 303, so that the support rod 301 first releases the abutting cooperation relationship with the support bearing 203. Then the connecting rod 403 continues to extend until the connecting rod 403 presses the pushing module 503. At this time, the pushing module 503 controls the pushing cylinder 502 to start working, and the pushing plate 501 pushes the completed winding material to the main rod 401. Similarly, when the connecting rod 403 is retracted, the connecting rod 403 first releases the pressing cooperation relationship with the pushing module 503, and the pushing module 503 first controls the pushing cylinder 502 to reset the pushing plate 501. Then, as the connecting rod 403 continues to retract, the connecting rod 403 releases the abutting cooperation relationship with the support module 303. At this time, the support module 303 controls the support cylinder 302, so that the support rod 301 relocks the abutting cooperation relationship with the support bearing 203. Until the connecting rod 403 is retracted into the main rod 401.

[0039] It should be noted that when the connecting rod 403 presses the pushing material module 503, the telescopic blocks 404 are all located in the communication rod 204, and the length of the connecting rod 403 is smaller than the length of the rolled material. Such a setting makes the front end of the rolled material located on the main rod 401 and the rear end of the rolled material located on the connecting rod 403 when the pushing plate 501 pushes the completed rolled rolled material out of the gas expansion shaft 201. When the connecting rod 403 is retracted, the surface height of the telescopic block 404 is higher than the surface of the side wall of the main rod 401, and the telescopic block 404 is limited by the telescopic groove 4031, so that the telescopic block 404 slides along the direction perpendicular to the axis of the connecting rod 403 and cannot slide along the axis of the connecting rod 403. Therefore, during the retraction of the connecting rod 403, the telescopic block 404 pushes the rear end of the completed rolled rolled material to move towards the main rod 401 until the connecting rod 403 is completely retracted into the main rod 401. At this time, the completed rolled rolled material is completely located on the main rod 401, and the process of removing the completed rolled rolled material out of the gas expansion shaft 201 is completed.

[0040] Further, the present scheme also includes a weight module arranged on the gas expansion shaft 201 for detecting the weight of the rolled material on the gas expansion shaft 201. The weight module is in communication connection with the gas expansion shaft 201. The weight of the rolled material is detected by the weight module, and then it is judged whether the rolled material is completed. When the weight module judges that the rolled material is completed by detecting the weight of the rolled material, the gas expansion shaft 201 starts to retract at this time, and the effect of being fitted with the winding drum of the rolled material is released. Otherwise, it will not be retracted, and the effect of being fitted with the winding drum of the rolled material will be continued to be locked, so as to avoid the relative sliding of the rolled material relative to the gas expansion shaft 201 when the rolled material is not completed. It should be noted that since the support assembly 3 and the material collecting assembly 4 of the present scheme are inconsistent with the existing structure, the way of replacing the new winding drum is also inconsistent with the winding drum on the market. The winding drum of the present scheme has a groove along the center axis of the cylinder in addition to the hollow cylinder on the market, so that the cylinder of the present scheme can be directly deformed through the groove on the top of the gas expansion shaft 201 to realize the coaxial fitting of the gas expansion shaft 201 and the cylinder.

[0041] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the scope of the technical scheme of the present application. Any modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application still belong to the scope of the technical scheme of the present application.
