[0002] Laminated metal composites are composed of two or more layers of different metals. These layers are perfectly bonded together through processes such as rolling, extrusion, fusion, explosive welding, and brazing, achieving desirable properties that differ from those of the individual metals.

[0019] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0020] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0021] Please refer to Figure 1 、 Figure 2 and Figure 3 The present invention provides a separation device 100 for a laminated metal composite material 101, comprising: a first clamping wheel group 1, a second clamping wheel group 2, a material separation guide assembly 4 and a third clamping wheel group 3 arranged in sequence along a first direction X.

[0022] The first clamping wheel assembly 1 and the second clamping wheel assembly 2 are both arranged on the feed side of the material distribution guide assembly 4, and are used to clamp the composite material 101 and jointly push it to the material distribution guide assembly 4. Since the thrust provided by a single clamping wheel assembly is slightly insufficient, and the more clamping wheel assemblies, the higher the synchronization requirements, two clamping wheel assemblies are used to provide thrust.

[0023] The material dividing guide assembly 4 includes a material dividing guide block 5 and a material dividing knife 6. The material dividing guide block 5 is used to guide the composite material 101 to the blade 61 of the material dividing knife 6, and after separating the upper layer of the composite material 101, continue to guide the lower layer of the composite material 101 along the first direction X to the third clamping wheel group 3.

[0024] The third clamping wheel assembly 3 is arranged on the discharge side of the material separation guide assembly 4 and is used for clamping and pulling the lower layer of the separated composite material 101 along the first direction X.

[0025] Each clamping wheel assembly includes a lower active clamping wheel 11 and an upper active clamping wheel 12. The lower active clamping wheel 11 is fixed in position, while the upper active clamping wheel 12 is positioned above the lower active clamping wheel 11 and has an adjustable vertical spacing therebetween. The axles of all lower active clamping wheels 11 and upper active clamping wheels 12 are perpendicular to the first direction X, and the highest points of all lower active clamping wheels 11 are located at the same height. In particular, the outer contours of the lower active clamping wheels 11 and upper active clamping wheels 12 are covered with multiple ridges 123 that can be pressed into the composite material 101. The ridges 123, which facilitate pressing into the composite material 101, can increase the friction coefficient to near unity, significantly improving the thrust applied to the composite material 101 for better cutting. Furthermore, the ridges 123 can be machined into stripes with equal spacing, and each ridge 123 extends perpendicular to the first direction X. These striped ridges perpendicular to the first direction X not only effectively increase thrust but also facilitate machining.

[0026] The separation device 100 also includes a driving device 9, which is arranged on the same side of the first clamping wheel group 1, the second clamping wheel group 2 and the third clamping wheel group 3, and is used to independently control each upper active clamping wheel 11 to move away from and approach its corresponding lower active clamping wheel 12, and drive all lower active clamping wheels 11 and all upper active clamping wheels 12 to have synchronous and identical linear speeds.

[0027] Optionally, the separation device 100 further includes a photoelectric sensor 8, which is disposed on the discharge side of the third clamping wheel assembly 3. The photoelectric sensor 8 is in communication with the drive device 9. When the photoelectric sensor 8 senses that the lower layer of the composite material 101 has passed through, the drive device 9 transmits a signal to the drive device 9. After receiving the signal, the drive device 9 controls the upper active clamping wheel 12 in the third clamping wheel assembly 3 to press downward, cooperating with the corresponding lower active clamping wheel 11 to clamp the lower layer of the composite material 101 and continue to convey it. This arrangement facilitates automatic clamping of the third clamping wheel assembly 3.

[0028] Preferably, after the drive device 9 controls the upper active clamping wheel 12 in the third clamping wheel assembly 3 to complete the downward pressure, the drive device 9 continues to control the two upper active clamping wheels 12 in the first clamping wheel assembly 1 and the second clamping wheel assembly 2 to lift upward. This arrangement can better maintain the stability of the material separation, because the material will stretch, and once the composite material 101 is long, it will be difficult to maintain synchronization. At this time, the composite material 101 already has interlayer cuts, causing stress concentration. The third clamping wheel assembly 3 can provide sufficient tension for material separation.

[0029] Optionally, the drive device 9 includes a synchronous transmission assembly 91 and three oil cylinders 92. The piston end of each oil cylinder 92 is respectively connected to an upper active clamping wheel 12 in a one-to-one correspondence, which is used to independently control the upper active clamping wheel 12 to move away from and approach the corresponding lower active clamping wheel 11. The synchronous transmission assembly 91 is arranged on the same side of the first clamping wheel group 1, the second clamping wheel group 2, and the third clamping wheel group 3, and is used to drive all lower active clamping wheels 11 and all upper active clamping wheels 12 to have synchronous and identical linear speeds. In this way, each clamping wheel group can be clamped and conveyed synchronously or individually at any time. Among them, the synchronous transmission assembly 91 can be composed of components such as gears, rotating shafts, and sprockets, which cooperate with the transmission to achieve the synchronous rotation of all lower active clamping wheels 11 and all upper active clamping wheels 12.

[0030] Optionally, the material dividing guide block 5 includes a front material dividing guide portion 51 and a rear material dividing guide portion 52 that are interconnected. A front material dividing guide groove 511 is provided in the front material dividing guide portion 51 for aligning the blade 61 of the material dividing knife 6 for feeding. The material dividing knife 6 is arranged at the top of the rear material dividing guide portion 52. The blade 61 of the material dividing knife 6 is tilted upward along the first direction X. A rear material dividing guide groove 521 is provided between the bottom of the blade 61 of the material dividing knife 6 and the top of the rear material dividing guide portion 52. The bottom surface heights of the rear material dividing guide groove 521 and the front material dividing guide groove 511 are the same and interconnected, and are used to continue to smoothly output the lower layer material of the separated composite material 101 along the first direction X. Such a material dividing guide block has a compact structure and a clever design, and can well realize the functions of material dividing and guiding. In addition, the blade height of the material dividing knife can be set according to the different thicknesses of the composite material, so as to facilitate alignment with the interface between the upper and lower layers of the composite material and realize the separation of composite materials of different specifications.

[0031] Optionally, the separation device 100 further includes a feed guide block 7 disposed between the first clamping wheel assembly 1 and the second clamping wheel assembly 2. A feed guide groove 71 extending along the first direction X is defined within the feed guide block 7. Because a certain amount of space is required for transmission between the first clamping wheel assembly 1 and the second clamping wheel assembly 2, a certain spacing exists. The provision of the feed guide block 7 effectively ensures that the composite material 101 does not deviate while moving along the first direction X within this spacing.

[0032] Preferably, the feed side of the feed guide trough 71 is in a trumpet shape that is larger on the outside and smaller on the inside. Such a shape facilitates the composite material 101 to enter the feed guide trough 71.

[0033] Optionally, the blade 61 of the dividing knife 6 is inclined with the inner side higher and the outer side lower. The arrangement of the blade 61 of the dividing knife 6 with the inner side higher and the outer side lower is to enable the upper layer of the separated composite material 101 to be spirally discharged outwards for automatic falling.

[0034] Optionally, the dividing knife 6 further includes an oil groove 62, which is opened on the blade 61 of the dividing knife 6 for cooling and lubricating the blade 61 of the dividing knife 6. This arrangement can improve the service life of the dividing knife 6.

[0035] Optionally, the blade 61 of the dividing knife 6 and the outlet of the front dividing guide groove 511 have a spacing of 2-3 mm in the first direction X. Such a spacing can prevent the upper layer of the composite material 101 from getting stuck without affecting the accuracy of the output of the blade 61.

[0036] Optionally, the dividing knife 6 is detachably mounted on the top of the dividing rear guide portion 52. This arrangement facilitates the replacement and maintenance of the dividing knife 6. In addition, since the material of the dividing knife 6 is generally more expensive, this separation arrangement can save costs.

[0037] The operating principle of the separation device 100 for a laminated metal composite material 101 according to one embodiment of the present invention is as follows:

[0038] When the separation device 100 is started, the driving device 9 controls the lower active clamping wheel 11 and the upper active clamping wheel 12 in the first clamping wheel group 1, the second clamping wheel group 2 and the third clamping wheel group 3 to start rotating synchronously and maintain the same linear speed, and then feeds the composite material 101 above the lower active clamping wheel 11 of the first clamping wheel group 1 and the second clamping wheel group 2, and then the driving device 9 controls the upper active driving wheels 12 of the first clamping wheel group 1 and the second clamping wheel group 2 to press down, so as to cooperate with their respective corresponding lower active clamping wheels 11 to clamp the fed composite material 101, so that the composite material 101 as a whole keeps moving synchronously along the first direction X, and then the guide groove 511 before the material is separated Under the guiding action, the composite material 101 moves straight toward the blade 61 of the dividing knife 6. Under the separating action of the blade 61, the upper layer of the composite material 101 after being cut on the composite material 101 moves obliquely upward along the blade 61. The lower layer of the composite material 101 continues to move downward along the first direction X under the guiding action of the guide groove 521 after dividing the composite material into the upper part of the lower active clamping wheel 11 of the third clamping wheel group 3. At this time, the driving device 9 controls the upper active clamping wheel 12 in the third clamping wheel group 3 to press down and cooperate with the lower active clamping wheel 11 to clamp the lower layer of the composite material 101, and starts to provide tension to the composite material 101 until the lower layer of the composite material 101 is completely separated and output.

[0039] The separation device for laminated metal composite materials of the present invention has a compact structure and ingenious design, can quickly and automatically separate and recover laminated metal composite materials, greatly improves the separation efficiency and recovery quality of composite materials, and stably realizes the automated separation of composite materials.

It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements that do not depart from the spirit and scope of the present invention are intended to be protected by the present invention.
