[0047] Please see Figures 1-6 The decorative film roll transfer mechanism shown includes a frame 1, a pushing device 2, and a placement device 3. The placement device 3 is mounted on the frame 1, and the pushing device 2 is located at the lower part of the frame 1 to push the roll to a designated position so that the placement device 3 can grab and transfer the roll.

[0048] The pushing device 2 includes a pushing base frame 201, a set of linear guide rail pairs 202, a support base plate 203, a set of support frames 204 symmetrically arranged on the left and right, and a pushing cylinder 205. The set of linear guide rail pairs 202 are symmetrically arranged on both sides of the pushing base frame 201, and the lower end face of the support base plate 203 is simultaneously connected to the slider on the set of linear guide rail pairs 202. The set of support frames 204 are symmetrically arranged at both ends of the support base plate 203, and each support frame 204 has an arc groove 206 at its upper end. The cylinder body of the pushing cylinder 205 is rigidly connected to the pushing base frame 201, and its telescopic rod is fixedly connected to the support base plate 203. The linear guide pair 202 provides guidance for the movement of the support base plate 203, ensuring that the support base plate 203 can move smoothly under the drive of the pusher cylinder 205; the arc groove 206 on the support frame 204 is adapted to the outer circle of the material roll mandrel on the material roll, which can provide good support for the material roll and prevent the material roll from rolling or deviating during the pushing process.

[0049] The placement device 3 includes a traction device 301 and a holding device 302. The holding device 302 is connected to the traction device 301 and can move linearly under the traction of the traction device 301.

[0050] The gripping device 302 includes an upper connecting plate 302a, a lower connecting plate 302b, a guide rail base plate 302c, a transmission screw pair 302d, a screw motor 302e, a linear optical axis 302f, a linear bearing 302g, a gripping cylinder 302h, an adapter plate 302j, a gripping column 302k, and a linear guide rail pair 302m. The guide rail base plate 302c is located between the upper connecting plate 302a and the lower connecting plate 302b. One end of the transmission screw pair 302d is connected to the upper end face of the lower connecting plate 302b through a screw connecting seat, and the other end passes through the upper connecting plate 302a and is connected to the rotating shaft of the screw motor 302e through a coupling. The body of the screw motor 302e is fixedly connected to the upper end face of the upper connecting plate 302a, and the screw nut seat on the transmission screw pair 302d is fixedly connected to the lower connecting plate 302b. The lead screw motor 302e drives the transmission lead screw pair 302d to rotate, which in turn drives the lower connecting plate 302b to move up and down through the lead screw nut seat, thereby realizing the height adjustment of the entire gripping device 302 to adapt to the gripping needs of material rolls at different height positions.

[0051] Two sets of linear optical axes 302f are arranged in a rectangular array. One end of each linear optical axis 302f is rigidly connected to the upper surface of the lower connecting plate 302b, and the other end is rigidly connected to the upper surface of the upper connecting plate 302a. The middle part is connected to the guide rail base plate 302c through a linear bearing 302g. The cooperation of the linear optical axes 302f and the linear bearing 302g provides stable guidance for the up and down movement of the lower connecting plate 302b, ensuring the accuracy and smoothness of the movement.

[0052] Two sets of linear guide rail pairs 302m are provided, and the two sets of linear guide rail pairs 302m are symmetrically arranged on both sides of the upper end face of the guide rail base plate 302c. A gripping cylinder 302h is provided between the two linear guide rail pairs 302m on the same side. The cylinder body of the gripping cylinder 302h is rigidly connected to the upper end face of the guide rail base plate 302c, and its telescopic rod is connected to a transition plate 302j. The transition plate 302j has a similar L-shaped structure, and the two transition plates 302j are symmetrically arranged. Each transition plate 302j is connected to the slider on a corresponding set of linear guide rail pairs 302m, and is also connected to the telescopic rod of the gripping cylinder 302h at the corresponding position. Linear guide rail pair 2 302m provides guidance for the movement of adapter plate 302j, and gripping cylinder 302h drives adapter plate 302j to move on linear guide rail pair 2 302m, thereby realizing the movement of gripping column 302k.

[0053] The lower ends of the two symmetrically arranged adapter plates 302j are rigidly connected to a gripping post 302k. The gripping post 302k is truncated conical in shape, which facilitates insertion into the hollow mandrel of the material roll. The truncated conical design of the gripping post 302k makes it easier to insert into the hollow mandrel of the material roll, and also allows it to form a good fit with the inner wall of the hollow mandrel, ensuring stable gripping.

[0054] The traction device 301 includes a reduction motor 301a, a set of sprocket assemblies 301b, a set of transmission chains 301c, and a set of chain fixing blocks 301d; the reduction motor 301a is fixedly mounted on the frame 1 at one end away from the gripping device 302; the sprocket assembly 301b includes two symmetrically arranged transmission sprockets 301ba, a connecting shaft 301bb, a bearing 301bc, and a support 301bd; the two transmission sprockets 301ba are symmetrically fixedly mounted on the connecting shaft 301bc. On 1bb, both ends of the connecting shaft 301bb are connected to the support base 301bd via the bearing 301bc. The support base 301bd is fixedly mounted on the frame 1. On the same side of the two sprocket assemblies 301b, each of the transmission sprockets 301ba has a transmission chain 301c. Each transmission chain 301c has a chain fixing block 301d, and each chain fixing block 301d is fixedly connected to the upper end face of the upper connecting plate 302a. The connecting shaft 301bb near the end of the reduction motor 301a is also connected to the output shaft of the reduction motor 301a.

[0055] The geared motor 301a drives the sprocket assembly 301b to rotate, which in turn drives the gripping device 302 to move linearly through the transmission chain 301c and the chain fixing block 301d, thereby realizing the transfer of the material roll.

[0056] The grasping device 302 is also equipped with a guide device 4, which includes a set of channel steel guide rails 401, a set of horizontal shafts 402, and guide wheels 403. The set of channel steel guide rails 401 are symmetrically arranged on both sides of the upper connecting plate 302a and rigidly connected to the upper end face of the frame 1. The middle part of the set of horizontal shafts 402 is rigidly connected to the lower end face of the upper connecting plate 302a, and each horizontal shaft 402 has a guide wheel 403 connected to both ends by bearings. The guide wheel 403 is engaged in the channel steel guide rail 401. The guide device 4 can guide and stabilize the grasping device 302 during its movement, preventing the grasping device 302 from deviating or shaking, and ensuring the smoothness of the transfer process.

[0057] Below the frame 1, there is also a storage device 5 for storing material rolls. The storage device 5 includes a base 501 and a material roll support plate 502 disposed on the upper surface of the base 501. Multiple material roll support plates 502 are arranged at equal intervals on both sides of the upper surface of the base 501. A second material roll support plate 503 is also provided between two adjacent material roll support plates 502. Both the first and second material roll support plates 502 have placement grooves 504 on their upper surfaces. The height of the second material roll support plate 503 is less than the height of the first material roll support plate 502. The placement grooves 504 on the first and second material roll support plates 502 and 503 are used to place material rolls, and the lower height of the second material roll support plate 503 better accommodates the shape of the material rolls, improving the stability of the material roll placement.

[0058] Working principle:

[0059] First, the decorative film roll is placed on the support frame 204 of the pushing device 2. The roll core is in contact with the arc groove 206. The pushing cylinder 205 is activated, and its telescopic rod extends, pushing the bracket base plate 203 to move on the linear guide rail pair 202, pushing the roll to the specified position that the placement device 3 can grasp.

[0060] Next, the lead screw motor 302e starts, driving the transmission lead screw pair 302d to rotate. Through the lead screw nut seat, the lower connecting plate 302b moves downward, thereby driving the gripping column 302k to descend to the height corresponding to the material roll mandrel. During this process, the linear optical shaft 302f and the linear bearing 302g cooperate to ensure the smooth movement of the lower connecting plate 302b.

[0061] Then, the gripping cylinder 302h is activated, its telescopic rod retracts, driving the adapter plate 302j to move inward on the linear guide rail pair 302m, so that the two gripping columns 302k approach each other and insert into the hollow shaft of the material roll, thereby achieving the gripping of the material roll.

[0062] After the gripping is completed, the lead screw motor 302e reverses, driving the lower connecting plate 302b to move upward and lift the material roll.

[0063] Subsequently, the geared motor 301a starts, driving the sprocket assembly 301b to rotate. Through the transmission chain 301c and chain fixing block 301d, the grabbing device 302 moves in a straight line under the guidance of the guide device 4 to the top of the storage device 5. During the movement, the guide wheel 403 rolls in the channel steel guide rail 401 to ensure that the grabbing device 302 moves smoothly.

[0064] Finally, the lead screw motor 302e drives the lower connecting plate 302b to move downward again, placing the material roll in the placement groove 504 of the material roll support plate 1 502 and the material roll support plate 2 503. The telescopic rod of the gripping cylinder 302h extends, driving the gripping column 302k to exit from the hollow shaft of the material roll, completing one material roll transfer operation.
