Description

Technical Field

[0001] This invention relates to the field of fixture technology, specifically an adaptive handling fixture for aluminum foil rolls. Background Technology

[0002] A hot stamping material made by directly rolling aluminum into thin sheets produces a stamping effect similar to that of pure silver foil, hence it is also called imitation silver foil. Because aluminum is soft, malleable, and has a silvery-white luster, the rolled sheets can be laminated onto offset paper with substances such as sodium silicate to create aluminum foil sheets, which can then be printed on.

[0003] In the aluminum foil production process, aluminum foil rolls need to be handled, so corresponding handling fixtures are used. However, the current fixtures, which clamp the aluminum foil rolls from all sides, have poor adaptability and result in low handling efficiency. Therefore, optimization is needed. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive handling fixture for aluminum foil rolls to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adaptive handling fixture for aluminum foil rolls includes a guide rail, on which a first clamping plate and a second clamping plate are slidably connected. The second clamping plate is connected to the first clamping plate via a clamping cylinder located on one side of the guide rail. Both the second and first clamping plates are equipped with positioning pins that cooperate with the aluminum foil roll. A fall prevention mechanism is installed at the bottom of the guide rail, with one end connected to the first clamping plate and the other end connected to the second clamping plate. A floating mechanism is installed on the side of the guide rail away from the clamping cylinder, with one end connected to the first clamping plate and the other end connected to the fall prevention mechanism.

[0007] As a further technical solution of the present invention: the fall protection mechanism includes a fixed plate, which is fixedly installed at the bottom center of the guide rail. A rotating shaft is installed inside the fixed plate, and a fixed frame is fixedly connected to the lower end of the rotating shaft. A first connecting rod is rotatably connected to the fixed frame at one end, and a second connecting rod is rotatably connected to the fixed frame at the other end. The end of the first connecting rod away from the fixed frame is rotatably connected to a first clamping plate, and the end of the second connecting rod away from the fixed frame is rotatably connected to a second clamping plate.

[0008] As a further technical solution of the present invention: a first auxiliary guide rail and a second auxiliary guide rail are installed on the guide rail and slidably connected thereto. The second auxiliary guide rail and the first auxiliary guide rail are symmetrically arranged about the fixing frame. The first clamping plate is fixedly installed on the upper end of the first auxiliary guide rail, and the second clamping plate is fixedly installed on the upper end of the second auxiliary guide rail.

[0009] As a further technical solution of the present invention: a first dust cover is installed at both ends of the first secondary guide rail, the first dust cover is sleeved on the outside of the guide rail and slidably connected thereto; a second dust cover is sleeved at both ends of the second secondary guide rail, the second dust cover is sleeved on the outside of the guide rail and slidably connected thereto.

[0010] As a further technical solution of the present invention: both the first dust cover and the second dust cover are accordion covers.

[0011] As a further technical solution of the present invention: the floating mechanism includes a floating cylinder, one end of which is rotatably connected to a fixed plate and the other end of which is rotatably connected to a first clamping plate.

[0012] As a further technical solution of the present invention: a bearing is installed inside the fixing plate, and the bearing is sleeved on the outside of the rotating shaft.

[0013] As a further technical solution of the present invention: a first fixed shaft and a third fixed shaft are fixedly installed inside the fixing frame. The third fixed shaft and the first fixed shaft are symmetrically arranged about the rotation axis. One end of the first connecting rod is sleeved outside the first fixed shaft and rotatably connected to it. The other end is installed with a second fixed shaft that is rotatably connected to it. The second fixed shaft is fixedly installed inside the first clamping plate. One end of the second connecting rod is sleeved outside the third fixed shaft and rotatably connected to it. The other end is installed with a fourth fixed shaft that is rotatably connected to it. The fourth fixed shaft is fixedly installed inside the second clamping plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: by setting a clamping cylinder in conjunction with an anti-fall mechanism and a floating mechanism, efficient and stable clamping of aluminum foil rolls is achieved. The floating mechanism can also compensate for positioning deviations, and the anti-fall mechanism can effectively protect the aluminum foil rolls from falling. In addition, the accordion cover improves the stability of sliding and also protects the aluminum foil rolls from contamination. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Example 1

[0022] like Figure 1 , 2 The aluminum foil roll adaptive handling fixture shown in Figure 3 includes a guide rail 1, which is a linear guide rail, preferably two rails, to ensure smooth operation. A first clamping plate 2 and a second clamping plate 4 are slidably connected to the guide rail 1. The second clamping plate 4 is connected to the first clamping plate 2 via a clamping cylinder 3. The clamping cylinder 3 is located on one side of the guide rail 1, meaning that the extension and retraction of the clamping cylinder 3 moves the first clamping plate 2 and the second clamping plate 4 closer or further apart. Both the second clamping plate 4 and the first clamping plate 2 are equipped with positioning pins 5 that cooperate with the aluminum foil roll. The positioning pins 5 engage with the winding holes of the aluminum foil roll to fix it in place. Then, the clamping cylinder 3 moves the first clamping plate 2 and the second clamping plate 4 closer together, thereby... Two fixed aluminum foil rolls are clamped together, which not only improves the fixing efficiency but also the handling efficiency. The bottom of the guide rail 1 is equipped with an anti-fall mechanism 6, which protects against falls. Specifically, one end of the anti-fall mechanism 6 is connected to the first clamping plate 2 and the other end is connected to the second clamping plate 4. A floating mechanism 7 is installed on the side of the guide rail 1 away from the clamping cylinder 3. One end of the floating mechanism 7 is connected to the first clamping plate 2 and the other end is connected to the anti-fall mechanism 6. The anti-fall mechanism 6 ensures the coordinated movement of the first clamping plate 2 and the second clamping plate 3, allowing them to move closer or further away synchronously under the restraint of the anti-fall mechanism 6. The floating mechanism 7 compensates for positioning deviations.

[0023] Furthermore, the fall protection mechanism 6 includes a fixed plate 8, which is fixedly installed at the bottom center of the guide rail 1. A rotating shaft 9 is installed inside the fixed plate 8, and a fixed frame 10 is fixedly connected to the lower end of the rotating shaft 9. A first connecting rod 11 is rotatably connected to the fixed frame 10 at one end, and a second connecting rod 12 is rotatably connected to the fixed frame 10 at the other end. The end of the first connecting rod 11 away from the fixed frame 10 is rotatably connected to the first clamping plate 2, and the end of the second connecting rod 12 away from the fixed frame 10 is rotatably connected to the second clamping plate 4. When clamped, the clamping cylinder 3 shortens, and the first clamping plate 2 and the second clamping plate 4 slide towards the center synchronously. The fixed frame 10 rotates through the cooperation of the first connecting rod 11 and the second connecting rod 12. This not only ensures the stability of the synchronous sliding of the first clamping plate 2 and the second clamping plate 4, but also supports the aluminum foil roll that is accidentally dropped, providing good protection.

[0024] Furthermore, to improve the sliding stability of the first clamping plate 2 and the second clamping plate 4, a first auxiliary guide rail 13 and a second auxiliary guide rail 16 are installed on the guide rail 1 and slidably connected thereto. The second auxiliary guide rail 16 and the first auxiliary guide rail 13 are symmetrically arranged about the fixing frame 10. The first clamping plate 2 is fixedly installed on the upper end of the first auxiliary guide rail 13, and the second clamping plate 4 is fixedly installed on the upper end of the second auxiliary guide rail 16. That is, by setting the first auxiliary guide rail 13 and the second auxiliary guide rail 16 to be respectively mounted on the two guide rails 1, the sliding stability of the first clamping plate 2 and the second clamping plate 4 is improved. To prevent debris from falling onto the guide rail 1 and affecting its sliding stability, a first dust cover 14 is installed at both ends of the first auxiliary guide rail 13. The first dust cover 14 is fitted over the outside of the guide rail 1 and slidably connected to it. A second dust cover 17 is fitted over both ends of the second auxiliary guide rail 16. The second dust cover 17 is fitted over the outside of the guide rail 1 and slidably connected to it. Preferably, the first dust cover 14 and the second dust cover 17 are both accordion covers. That is, by covering the guide rail 1 with accordion covers, not only can debris be prevented from adhering to the guide rail 1, but the lubricating oil on the guide rail 1 can also be effectively prevented from contaminating the aluminum foil roll.

[0025] Furthermore, the floating mechanism 7 includes a floating cylinder 15, one end of which is rotatably connected to the fixed plate 8, and the other end is rotatably connected to the first clamping plate 2.

[0026] Example 2

[0027] This embodiment is further optimized based on Embodiment 1, such as... Figure 4 As shown, a bearing 18 is installed inside the fixing plate 8, and the bearing 18 is sleeved on the outside of the rotating shaft 9, that is, the rotational stability of the fixing frame 10 is improved by setting the bearing 18.

[0028] Furthermore, a first fixed shaft 19 and a third fixed shaft 21 are fixedly installed inside the fixing frame 10. The third fixed shaft 21 and the first fixed shaft 19 are symmetrically arranged about the rotating shaft 9. One end of the first connecting rod 11 is sleeved outside the first fixed shaft 19 and rotatably connected to it, and the other end is installed with a second fixed shaft 20 rotatably connected to it. The second fixed shaft 20 is fixedly installed inside the first clamping plate 2. One end of the second connecting rod 12 is sleeved outside the third fixed shaft 21 and rotatably connected to it, and the other end is installed with a fourth fixed shaft 22 rotatably connected to it. The fourth fixed shaft 22 is fixedly installed inside the second clamping plate 4.
