Description

Technical Field

[0001] The utility model belongs to the technical field of wet wipe packaging, and particularly relates to a bracket for a wet wipe packaging film roll. Background Art

[0002] Wet wipes are increasingly widely used in daily life. The market demand for wet wipes is constantly increasing, and the output of wet wipes is also constantly increasing. When all processes of wet wipes are completed, packaging film is needed to bag and pack the wet wipes. The packaging film is generally sleeved on a bracket and is detached from the bracket for use during use.

[0003] The patent with the authorization announcement number of "CN221439855U" discloses a bracket for a wet wipe packaging film roll, which includes a bottom plate. An installation plate is fixedly arranged at the top of the bottom plate. A motor is fixedly arranged on one side of the installation plate. A rotating shaft is movably arranged on one side of the installation plate. The output shaft of the motor is fixedly connected with one end of the rotating shaft. The above patent realizes the positioning of film rolls with different sizes by setting a limiting rod, an arc-shaped plate, a hinge block, a threaded block and a hinge rod.

[0004] Although the above patent solves the positioning of film rolls with different inner diameters, for some film rolls with too long lengths, it is far from enough to only position the inside of the film roll, because the two ends of the film roll with too long length are too heavy, which will cause the film roll to bend, and some soft and thin film rolls are prone to bend and curl after being placed for a long time.

[0005] In view of the above technical problems, the present application proposes a solution. Content of the Utility Model

[0018] 3. All the rolling devices and the outer side of the top plate of the present utility model are made of sponge material, which can not only fix the film roll but also cause no damage to the film roll. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Such as Figures 1 to 12As shown in the figure, a bracket for a wet wipe packaging film roll includes a first clamping mechanism 1. The first clamping mechanism 1 includes a first base 102, and the first base 102 is in an "L" shape. Four groups of fixedly connected bases are installed at the bottom of the first base 102. When the first base 102 is lifted, a first driving device 101 is fixedly connected to the outer side of the bottom of the first base 102. The first driving device, which is a servo motor in the present invention, can accurately control the moving direction. A third driving device 104 is fixedly connected to the outer side of the upper part of the first base 102 by bolts. The output end of the third driving device (104) is connected to a middle telescopic mechanism (4). The first rotating device 103 is rotatably connected to the inner side of the upper part of the first base 102. Three curved slots are provided on the first rotating device 103. A first runner 103A is fixedly connected to the outside of the first rotating device 103. The first driving device (101) drives the first runner (103A) to rotate. The middle of the first rotating device 103 is in a hollow form to facilitate the middle telescopic mechanism 4 to pass through. A first fixing device 105 fixedly connected to the first base 102 is provided inside the first rotating device 103. A fixing column is provided on the first fixing device 105 and is fixed on the first base 102. The first fixing device 105 is rotatably connected to the first rotating device 103. Three groups of first side clamping mechanisms 3 are slidably connected to the inside of the first fixing device 105. Two fixing plates 106 for limiting the middle telescopic mechanism 4 are fixedly connected to the first rotating device 103.

A first inner rolling device 303 is fixedly connected to the side of the first bracket 301 close to the middle telescopic mechanism 4. The first inner rolling device 303 is used to support the film roll from the inside of the film roll. A first extending end 304 is fixedly connected to the other side of the first bracket 301. The first extending end 304 has two shapes. The first is a cube structure for sliding connection with the straight slot provided on the first fixing device 105 to prevent rotation. The second is a cylindrical structure for sliding connection with the curved slot on the first rotating device 103 to facilitate telescoping. An outer rolling device 6 that cooperates with the first inner rolling device 303 is slidably connected to the first bracket 301.

A first rotating ring 404 and a second rotating ring 405 are rotatably connected to the threaded rod 406. The first rotating ring 404 has clockwise threads, and the second rotating ring 405 has counterclockwise threads. Four groups of first connecting rods 402 are rotatably connected to the first rotating ring. The other sides of the four groups of first connecting rods 402 are respectively rotatably connected to four groups of top plates 401. The top plates 401 are arc-shaped, aiming to increase the contact area between the top plates 401 and the inside of the film roll and increase friction. Four groups of second connecting rods 403 are rotatably connected to the second rotating ring 405. The other sides of the four groups of second connecting rods 403 are rotatably connected to the corresponding top plates 401. The other side of the threaded rod 406 is rotatably connected to a second clamping mechanism 2 that can move.

[0038] As Figure 2 and Figure 3 shown, the second clamping mechanism 2 includes a second base 201. Four groups of universal wheels 202 are fixedly connected to the bottom of the second base 201, facilitating the removal of the second clamping mechanism 2 before installing the film roll. A second driving device 203 is fixedly connected to one side of the bottom of the second base 201. A second rotating device 204 is rotatably connected to the upper part of the second base 201. A second runner 206 is fixedly connected to one side of the second rotating device 204. The second runner 206 is rotationally connected to the second driving device 203 through a chain. An opening is provided on the second base 201 to facilitate the passing of a belt or a chain. A second fixing device 205 fixedly connected to the second base 201 is provided on the other side of the second runner 206. Three groups of second side clamping mechanisms 5 are slidably connected to the second fixing device 205.

[0039] As Figure 11As shown in the figure, the second side clamping mechanism 5 includes a second bracket 501. A second inner rolling device 503 is fixedly connected to one side of the second bracket 501 close to the middle telescopic mechanism 4. A second extending end 504 is fixedly connected to the other side of the second bracket 501 close to the middle telescopic mechanism 4. The second extending end 504 is slidably connected to the second fixing device 205 and is also slidably connected to the second rotating device 204. A second locking ring 505 is fixedly connected to the other side of the second bracket 501. An outer rolling device 6 is slidably connected to one side of the second bracket 501 close to the second inner rolling device 503. A second elastic device 502 is fixedly connected inside the second bracket 501. The fixing ring 603 is fixedly connected to the second elastic device 502.

[0040] The outer surfaces of the top plate 401, the first inner rolling device 303, the second inner rolling device 503, and the rolling device 601 are made of sponge material.

[0041] Those skilled in the art can use the existing technologies they have mastered, such as installing corresponding mechanical limit switches or photoelectric sensors, to limit the specified positions of each executing component during the following actions; to achieve automated operation, the present utility model can adopt numerical control technology or PLC to control the actions of each executing component.

[0042] The practical process of the present utility model: After starting the device, the third driving device 104 rotates, driving the threaded rod 406 to rotate. The first rotating ring 404 and the second rotating ring 405 located on the threaded rod 406 start to move away from each other, causing the top plate 401 to approach the threaded rod 406. When it reaches the closest position, the first driving device 101 rotates, driving the first rotating device 103 and then driving the three first side clamping mechanisms 3 to approach the middle and stop rotating. Manually fix the locking buckle 604 on the outer rolling device 6 to the first locking ring 305 on the first side clamping mechanism 3. The outer rolling device 6 on the second clamping mechanism 2 is fixed to the second locking ring 505 on the second side clamping mechanism 5 in the same way. Move the operated second clamping mechanism 2 out of the working area through the universal wheels 202 at the bottom of the second clamping mechanism 2. At the connection between the middle telescopic mechanism 4 and the first clamping mechanism 1, the structural stiffness is strong. The middle telescopic mechanism 4 can be fully coordinated with the first clamping mechanism 1 through the first fixing device 105, the first rotating device 103, and the first base 102.

[0043] The membrane roll is hoisted in along one side of the middle telescopic mechanism 4. One end of the membrane roll is inserted between the first inner rolling device 303 and the rolling device 601. The third driving device 104 is started to drive the middle telescopic mechanism 4 to extend the top plate 401 outwards so that the top plate 401 presses against the membrane roll. Then, the locking buckle 604 is manually disengaged from the first locking ring 305, and the rolling device 601 returns to its position under the pulling force of the first elastic device 302 and presses on the upper layer of the membrane roll. The first driving device 101 is started to rotate the first rotating device 103, and the three groups of first side clamping mechanisms 3 rotate outwards, and the first inner rolling device 303 presses against the inner side of the membrane roll. After the installation is completed, the second clamping mechanism 2 returns to its position, and the middle telescopic mechanism 4 enters the second fixing device 205. The other end of the membrane roll enters between the rolling device 601 and the second inner rolling device 503, and the locking buckle 604 is manually disengaged from the second locking ring. Finally, the first base 102 and the second base 201 are fixed with bolts. After the membrane roll is installed, the equipment for hoisting the membrane roll is removed from the membrane roll to ensure that the middle telescopic mechanism 4 will not be damaged due to the weight of the membrane roll during the hoisting process.

[0044] Finally, although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
