[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Specific implementation examples are given below.
[0023] like Figures 1 to 4As shown in the figure, an intelligent transmission and tensioning mechanism for bubble wrap in packaging according to an embodiment of the present invention includes a support plate 1, a first motor 11 fixed to the top of the support plate 1, a telescopic shaft 14 slidably connected to the bottom output end of the first motor 11, a first fixing block 13 fixed to the bottom of the telescopic shaft 14, a sliding groove at the bottom of the support plate 1 and a limiting plate 12 slidably connected thereto, four of which are rotatably connected between the limiting plate 12 and the first fixing block 13, two of which are located on each side of the limiting plate 12 and the first fixing block 13. In operation, the bubble wrap to be moved is rolled up and placed on the ground, the first motor 11 is started, causing the first motor 11 to drive the telescopic shaft 14 downwards, causing the telescopic shaft 14 to drive the first fixing block 13 towards... The device moves downwards, and the first fixed block 13, in conjunction with the connecting arm 15 on the side wall, moves the limiting plate 12 toward the outer wall of the first fixed block 13. After the limiting plate 12 has moved closer, it is placed into the hole of the bubble wrap. The first motor 11 is then started again, causing the first motor 11 to move the telescopic shaft 14 upwards. The telescopic shaft 14 then moves the first fixed block 13 upwards, causing the first fixed block 13, in conjunction with the connecting arm 15 on the side wall, to push the limiting plate 12 outwards. Through the cooperation of the four limiting plates 12, the bubble wrap roll holes are tensioned. With the above structure, the push-type tensioning structure combined with the open mechanical structure allows the device to perform tensioning work quickly while also enabling rapid daily maintenance, increasing the practicality of the device.
[0024] like Figures 1 to 4 As shown, the side wall of the bearing plate 1 is fixed to the connecting plate 2, the inclined surface of the connecting plate 2 is fixed to the first fixing plate 21, the side wall of the first fixing plate 21 is fixed to the second fixing plate 23, the side wall of the second fixing plate 23 is fixed to the sliding block 22, the sliding block 22 and the second fixing plate 23 are rotatably connected by bolts 24, and the side wall of the sliding block 22 is slidably installed with the second fixing block 25. During operation, after the tensioning assembly completes the tensioning work, the bearing plate 1 is pushed upward, causing the bearing plate 1 to drive the connecting plate 2, causing the connecting plate 2 to drive the first fixing plate 21, the first fixing plate 21 to drive the second fixing plate 23, and the second fixing plate 23 to drive the sliding block 22 to move upward. The second fixing block 25 provides support for the sliding block 22, allowing the bubble film roll to be lifted, facilitating the next step of movement. Through the above structure, the sliding movement method allows the device to quickly lift the bubble film after tensioning, enabling the device to quickly proceed to the next operation and increasing the practicality of the device.
[0025] like Figures 1 to 4As shown, the inclined surface of the connecting plate 2 is fixed to the second rotating shaft 31, the side wall of the second rotating shaft 31 is rotatably connected to the first rotating shaft 3, the side wall of the first rotating shaft 3 is fixed to the first fixing plate 21, the bottom of the first rotating shaft 3 is fixed to the third fixing block 32, and the bottom of the third fixing block 32 is fixed to the connecting plate 2. During operation, by rotating the second rotating shaft 31, the second rotating shaft 31 drives the connecting plate 2 to rotate, which in turn drives the bearing plate 1 to rotate, changing the bubble wrap roll from a vertical state to a horizontal state. This further facilitates the next step of the bubble wrap roll operation. Through the above structure, the state of the bubble wrap can be quickly changed by rotation, making the next step of the bubble wrap operation more convenient.
[0026] like Figures 1 to 4 As shown, a second motor 41 is fixed to the top of the second fixed block 25, and a third rotating shaft 4 is fixed to the bottom output end of the second motor 41. The third rotating shaft 4 passes through the second fixed block 25 and through the sliding block 22. The connection between the third rotating shaft 4 and the sliding block 22 is provided with the same thread. When working, the second motor 41 is started, which drives the third rotating shaft 4 to rotate. Through the thread at the connection between the outer wall of the third rotating shaft 4 and the sliding block 22, the sliding block 22 is moved upward. The second motor 41 is rotated in the opposite direction, which moves the sliding block 22 downward. With the help of the tensioning structure and the steering structure, the bubble wrap roll can be moved more conveniently. Through the above structure, the device is driven by electricity, which enables the device to lift the bubble wrap more accurately and increases the practicality of the device.
[0027] like Figures 1 to 4 As shown, the second fixing block 25 is fixed to the bottom of the stabilizing block 5. During operation, the stabilizing block 5 provides good support for the device. Through the above structure, the device can be more stable during operation, increasing the practicality of the device.
[0028] like Figures 1 to 4 As shown, mounting plates 61 are fixed to the top of both ends of the stabilizing block 5, and casters 6 are fixed to the bottom of the mounting plates 61. The stabilizing block 5 has mounting grooves on both sides and is rotatably connected to the mounting plates 61. During operation, by pushing the second fixing block 25, the second fixing block 25 drives the bottom stabilizing block 5 to move, which in turn drives the mounting plates 61 to move. The casters 6 at the bottom of the mounting plates 61, in conjunction with the sliding shaft 62, enable the device to move quickly. Through the above structure, the use of multiple pulleys makes the movement of the device more convenient, reduces the labor cost of movement, and increases the practicality of the device.
[0029] like Figures 1 to 4 As shown, handles 7 are fixed to both sides of the second fixing block 25. When working, by holding the handles 7, the worker can push the device more quickly and conveniently. Through the above structure, the worker can move the device more conveniently and quickly, increasing the practicality of the device.
[0030] During operation, the bubble wrap roll to be moved is placed upright on the ground. The first motor 11 is started, causing the first motor 11 to drive the telescopic shaft 14 downwards. The telescopic shaft 14 then drives the first fixing block 13 downwards. The first fixing block 13, in conjunction with the connecting arm 15 on the side wall, moves the limiting plate 12 towards the outer wall of the first fixing block 13. After the limiting plate 12 has moved towards the outer wall, it is placed into the cavity of the bubble wrap. The first motor 11 is started again, causing the first motor 11 to drive the telescopic shaft 14 upwards. 4. The first fixing block 13 moves upward, cooperating with the connecting arm 15 on the side wall to push the limiting plate 12 outward. The four limiting plates 12 work together to tension the bubble wrap roll holes. After the tensioning assembly completes the tensioning, the bearing plate 1 is pushed upward, causing the bearing plate 1 to drive the connecting plate 2, which in turn drives the first fixing plate 21. The first fixing plate 21 drives the second fixing plate 23, which in turn drives the sliding block 22 upward. The second fixing block 25 then controls the sliding block 22. The device forms a support, lifting the bubble wrap roll for easier movement. Rotating the second rotating shaft 31 rotates the connecting plate 2, which in turn rotates the bearing plate 1, changing the bubble wrap roll from a vertical to a horizontal position, further facilitating its next operation. Starting the second motor 41 rotates the third rotating shaft 4, which engages with the threaded connection between the outer wall of the third rotating shaft 4 and the sliding block 22, causing the sliding block 22 to move upwards. Reversing the rotation of the second motor 41 moves the sliding block 22 downwards. This, combined with the tensioning and steering structures, facilitates the movement of the bubble wrap roll. The stabilizing block 5 provides good support. Pushing the second fixing block 25 moves the bottom stabilizing block 5, which in turn moves the mounting plate 61. The universal wheels 6 at the bottom of the mounting plate 61, in conjunction with the sliding shaft 62, allow for rapid movement of the device. Holding the handle 7 allows workers to push the device quickly and easily.
