[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-6 As shown, this utility model discloses a device for detecting the adhesion of aluminum film patterns, including a worktable 1, a friction module 2, flattening modules 3 located on the left and right sides of the friction module 2, and a synchronous belt 4 for moving the aluminum film 8 left and right on the worktable 1. The aluminum film 8 to be tested is placed on the synchronous belt 4 and moved to below the friction module 2. The movement of the synchronous belt 4 is then paused. The flattening modules 3 are positioned on the left and right sides of the aluminum film 8 to hold it in place. The friction module 2 is then activated to rub the surface of the aluminum film 8. After rubbing the surface of the aluminum film 8, it is removed from the synchronous belt 4 for observation. If the pattern on the aluminum film 8 falls off during the operation of the friction module 2, it indicates that the ink adhesion on its surface needs improvement. If the pattern on the aluminum film 8 is still clearly visible on the surface after being removed from the synchronous belt 4, it passes the test and can proceed to the next inspection stage. In the testing process, the friction module 2 includes a rotating roller 21, a brush sleeve 22 sleeved on the rotating roller 21, and fixed seats 23 located on the left and right sides of the rotating roller 21. The rotating roller 21 is rotatably mounted on the fixed seats 23. The brush sleeve 22 is circumferentially provided with a plurality of bristles 221. The brush sleeve 22 is made of a material that is easily deformable, such as rubber, and includes an upper connecting plate 222 and a lower connecting plate 223. The upper connecting plate 222 and the lower connecting plate 223 are detachably connected by bolts or other means. As the usage time increases, if the bristles 221 on the brush sleeve 22 wear out, the upper connecting plate and the lower connecting plate of the brush sleeve 22 can be separated to remove the brush sleeve 22 from the rotating roller 21 for replacement. After the new brush sleeve 22 is sleeved on the rotating roller 21, the upper connecting plate and the lower connecting plate are connected to fix the new brush sleeve 22 on the rotating roller 21. Since the brush sleeve 22 can be replaced, the service life of the friction module 2 can be effectively improved.

[0032] The upper connecting plate 222 is provided with an upper mounting section 2221, the lower connecting plate 223 is provided with a lower mounting section 2231, the upper end faces of the upper mounting section 2221 and the lower mounting section 2231 are flush with the upper end face of the brush hair 221, the upper mounting section 2221 is bolted with the lower mounting section 2231, the upper mounting section 2221 is provided with a bushing, the lower mounting section 2231 is provided with a screw hole corresponding to the bushing, a bolt (not shown in the figure) is inserted into the bushing and threaded with the screw hole, the rotating roller 21 is provided with a plurality of limiting insertion blocks 213 protruding therefrom, and the brush sleeve 22 is provided with limiting insertion grooves 224 corresponding to the limiting insertion blocks 213. 1. Since the upper mounting section 2221 and the lower mounting section 2231 are flush with the upper end face of the brush hair 221, when the rotating roller 21 drives the brush sleeve 22 to rotate, the upper mounting section 2221 and the lower mounting section 2231 will not protrude compared with the brush hair 221, so that the rotating brush sleeve 22 can stably rub the aluminum film 8; 2. During the installation of the brush sleeve 22, since each limiting insertion block 213 on the rotating roller 21 falls into the corresponding limiting insertion groove 224, after the brush sleeve 22 is installed on the rotating roller 21, the brush sleeve 22 cannot rotate compared with the rotating roller 21, so that the brush sleeve 22 can be stably sleeved on the rotating roller 21 and rotate with the rotating roller 21 to realize the friction of the brush hair 221 on the surface of the aluminum film 8; 3. Since the upper mounting section 2221 and the lower mounting section 2231 are bolted, and the bolt is a common general part, by rotating the bolt, the upper mounting section 2221 and the lower mounting section 2231 can be fixed together or separated, which brings convenience to the operation.

[0033] The rotating roller 21 includes a front limiting disc 211 and a rear limiting disc 212, the front limiting disc 211 abuts against the front side of the brush sleeve 22, and the rear limiting disc 212 abuts against the rear side of the brush sleeve 22. Since the front limiting disc 211 and the rear limiting disc 212 are present on the rotating roller 21, after the brush sleeve 22 is sleeved on the rotating roller 21 in the state that the upper mounting section 2221 and the lower mounting section 2231 are separated, the front and rear sides of the brush sleeve 22 will abut against the front limiting disc 211 and the rear limiting disc 212 respectively, so that the brush sleeve 22 cannot move in the front-rear direction of the rotating roller 21, and since the brush sleeve 22 cannot rotate compared with the rotating roller 21 due to the action of each limiting insertion block 213, the front limiting disc 211 and the rear limiting disc 212 can jointly act with the limiting insertion block 213 to facilitate the stable installation of the brush sleeve 22 on the rotating roller 21.

[0034] The cooperation motor 5 is fixedly connected with the rotating roller 21 through a key connection or the like. Since the cooperation motor 5 is fixed with the rotating roller 21, when the cooperation motor 5 is started, the rotating roller 21 will rotate with the cooperation motor 5 output shaft, and the brush sleeve 22 fixed with the rotating roller 21 will rotate, so that the bristles 221 at different positions of the brush sleeve 22 continuously contact the surface of the aluminum film 8 to realize friction on the aluminum film 8.

[0035] The linkage module 6 includes a left synchronous wheel 61 fixedly connected with the left rotating shaft 41 through welding or the like, a right synchronous wheel 62 fixedly connected with the right rotating shaft 42 through welding or the like, a belt 63 arranged between the left synchronous wheel 61 and the right synchronous wheel 62, and a driving motor 64 fixedly connected with the left synchronous wheel 61 through welding, a key connection or the like. Since the left synchronous wheel 61 on the front rotating shaft and the right synchronous wheel 62 on the rear rotating shaft exist, when the driving motor 64 is started, the left synchronous wheel 61 can be driven to rotate to make the left rotating shaft 41 rotate, and the rotating left synchronous wheel 61 can transmit the torque to the right synchronous wheel 62 through the belt 63 to drive the right rotating shaft 42 to rotate, so that the left rotating shaft 41 and the right rotating shaft 42 are synchronously rotated to drive the synchronous belt 4 to move, so that the aluminum film 8 placed on the left side of the synchronous belt 4 can move rightward with the movement of the synchronous belt 4. When the aluminum film 8 is below the friction module 2, the driving motor 64 is turned off, so that the left rotating shaft 41 and the right rotating shaft 42 stop rotating, and the aluminum film 8 stays below the friction module 2. When the friction on the pattern on the aluminum film 8 by the friction module 2 is completed, the driving motor 64 is started again to make the synchronous belt 4 continue to move, so that the aluminum film 8 is driven to move rightward, and the quality inspector can take the aluminum film 8 from the right side of the synchronous belt 4 to observe whether the pattern on the surface of the aluminum film 8 is detached.

[0036] Further, the driving module 7 is also included, each of the flattening modules 3 includes a mounting bracket 31, each of the mounting brackets 31 is respectively located on the left and right sides of the fixed seat 23, each of the flattening modules 3 further includes a flattening plate 32 rotatably mounted on the mounting bracket 31, a lifting seat 33 rotatably mounted with the flattening plate 32, and a movable rod 34 fixed with the lifting seat 33 by welding, bonding or the like, each of the flattening plates 32 is made of flexible material such as rubber, each of the movable rods 34 is slidably installed on the workbench 1 along the up-down direction, the driving module 7 includes a pressing plate 71 fixedly connected with each of the movable rods 34 by welding or the like, a screw rod 72 rotatably mounted on the workbench 1, and a hand wheel 73 located below the screw rod 72, the pressing plate 71 is threadedly connected with the screw rod 72, 1. Since each of the flattening plates 32 is made of flexible material, when the flattening plate 32 is driven to rotate downward to contact the aluminum film 8 to realize the pressing process of the aluminum film 8, the flattening plate 32 of flexible material can reduce the damage to the aluminum film 8 during pressing to ensure the integrity of the aluminum film 8; 2. Since each of the movable rods 34 is slidably installed on the workbench 1 along the up-down direction, after an upward force is applied to each of the movable rods 34, each of the movable rods 34 can drive the corresponding lifting seat 33 to move downward, and since each of the lifting seats 33 is rotatably connected with the corresponding flattening plate 32, during the movement of each of the movable rods 34, the part of the corresponding flattening plate 32 connected with the corresponding lifting seat 33 can be rotated upward to separate from the aluminum film 8 located on the synchronous belt 4; 3. Since each of the movable rods 34 is fixed with the pressing plate 71, and the pressing plate 71 is threadedly connected with the screw rod 72 rotatably mounted on the workbench 1, during the rotation of the screw rod 72 by applying torque to the hand wheel 73, the pressing plate 71 located on the screw rod 72 can be moved along the up-down direction, and with the up-down movement of the pressing plate 71, each of the movable rods 34 fixed with the pressing plate 71 can be moved up and down to drive the corresponding flattening plate 32 to move up and down to contact or separate from the aluminum film 8.

[0037] Preferably, the hand wheel 73 is circumferentially spaced apart with a plurality of grooves 731, since the hand wheel 73 is circumferentially provided with a plurality of grooves 731, the arrangement of each of the grooves 731 can effectively improve the roughness of the circumference of the hand wheel 73 to increase the circumferential friction of the hand wheel 73, thereby reducing the occurrence of slipping between the operating tool or hand and the hand wheel 73 during the rotation of the hand wheel 73.

[0038] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
