It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0028] This application provides a top-feeding device 100, such as... Figures 1 to 3 As shown, the top material device 100 includes: a plurality of lifting components 10, each of the lifting components 10 including a first connecting rod 11, the two ends of the first connecting rod 11 being connected to the driving end of a lifting drive component 12 respectively, the first connecting rod 11 being provided with at least two rolling support components 20, the rolling support component 20 including a fixed rod (not shown), a mounting base 21, and at least two universal rolling components 22 provided on the mounting base 21; the mounting base 21 is provided with a waist hole 23, the fixed rod passing through the waist hole 23 and connecting to the first connecting rod 11.

[0029] The working principle of the top-feeding device 100 provided in this application embodiment is as follows: Figures 4 to 6 As shown, the top-loading device 100 is used in a laser cutting equipment. The laser cutting equipment includes a worktable 400, which has a through slot for the first connecting rod 11 to pass through. The lifting drive 12 is placed on the plane. When no material is loaded, the first connecting rod 11 is located below the worktable 400. When loading material, the lifting drive 12 drives the first connecting rod 11 to move upward and pass through the through slot of the worktable 400. The operator places the plate to be cut on the universal rolling parts 22 of the multiple lifting components 10. Then, the lifting drive 12 drives the first connecting rod 11 to move downward and drives the universal rolling parts 22 to move downward. When the universal rolling parts 22 are located below the worktable 400, the plate to be cut is placed on the worktable 400, thus completing the loading process.

[0030] When the material needs to be adjusted, the lifting drive 12 drives the first connecting rod 11 to move upward and pass through the through slot of the worktable 400. The material to be cut is lifted by the universal rolling element 22, and then the operator adjusts the material to be cut. Subsequently, the lifting drive 12 drives the first connecting rod 11 to move downward and drives the universal rolling element 22 to move downward. When the universal rolling element 22 is below the worktable 400, the material to be cut is placed on the worktable 400, thus completing the adjustment.

[0031] When the position of the rolling support assembly 20 needs to be adjusted to accommodate different sizes of cutting plates, the fixing rod is released to facilitate the movement of the mounting base 21. After the mounting base 21 is moved to the required position, the fixing rod is then fixed together with the first connecting rod 11. When the mounting base 21 is moved, the position of the fixing rod in the waist hole 23 also moves. The size of the waist hole 23 can be set according to actual needs.

[0032] The beneficial effects of the top-feeding device 100 provided in this application embodiment are as follows: a rolling support assembly 20 is provided on the first connecting rod 11, and the universal rolling element 22 of the rolling support assembly 20 provides support for the plate. When adjusting the plate, scratches on the back of the plate can be avoided. In addition, the position of the universal rolling element 22 can be adjusted by the fixing rod, the mounting base 21 and the waist hole 23 to adapt to different sizes of plates to be cut, thereby improving the adaptability and utilization rate of the top-feeding device 100.

[0033] In this embodiment, the fixing rod is a threaded rod, which includes a rod part and a head. The head is used to abut against the end face of the mounting base 21 with a waist hole 23, and the rod part is threadedly connected to the first connecting rod 11.

[0034] In this embodiment, the universal rolling element 22 is connected to the mounting base 21 via a threaded rod.

[0035] In this embodiment, the lifting drive component 12 is a vertical cylinder, and the driving end is a cylinder rod.

[0036] In this embodiment, the universal rolling element 22 is a universal ball or a universal roller.

[0037] like Figure 3 As shown, the rolling support assembly 20 further includes a buffer pad 24; the buffer pad 24 is disposed between the universal rolling element 22 and the mounting base 21, and / or, the buffer pad 24 is disposed between the mounting base 21 and the first connecting rod 11.

[0038] In this embodiment, a buffer pad 24 is provided between the universal rolling element 22 and the mounting base 21 to reduce the impact on the mounting base 21 and the first connecting rod 11 when the plate to be cut comes into contact with the universal rolling element 22. It can also reduce the impact on the lifting drive element 12, thereby improving the service life of the top material device 100.

[0039] In another embodiment, a buffer pad 24 is disposed between the mounting base 21 and the first connecting rod 11 to reduce the impact on the first connecting rod 11 and the lifting drive component 12 when the plate to be cut comes into contact with the universal rolling component 22, thereby improving the service life of the top material device 100.

[0040] Further, the mounting base 21 includes a connecting plate 211, a support rod 212, and a mounting rod 213. The connecting plate 211 and the mounting rod 213 are horizontally arranged. The two ends of the support rod 212 are respectively connected to the middle of the connecting plate 211 and the mounting rod 213. The two ends of the mounting rod 213 away from the connecting plate 211 are respectively provided with the universal rolling element 22. The two ends of the connecting plate 211 are respectively provided with the waist hole 23. The connecting plate 211 is connected to the first connecting rod 11 through the fixing rod.

[0041] In this embodiment, a waist hole 23 is provided on the connecting plate 211, and a universal rolling element 22 is provided on the mounting rod 213. The mounting rod 213 and the connecting plate 211 are connected by a support rod 212, so that there is a space for the operator to adjust the fixing rod between the connecting plate 211 and the mounting rod 213, so that the operator can perform relevant operations on the fixing rod.

[0042] like Figure 1 As shown, the lifting assembly 10 further includes a second connecting rod 13, the first connecting rod 11 is arranged along a first direction, the second connecting rod 13 is arranged along a second direction, the first direction and the second direction are perpendicular to each other, and the second connecting rod 13 connects to a plurality of the first connecting rods 11.

[0043] In this embodiment, multiple first connecting rods 11 are connected together by a second connecting rod 13. When multiple lifting drive components 12 drive the first connecting rods 11 to move upward, the inconsistency in the lifting amplitude or speed of the multiple first connecting rods 11 can be reduced, so that the universal rolling components 22 provided on the first connecting rods 11 are located on the same horizontal plane, avoiding the problem of the plate tilting and slipping when placed on the top material device 100, thereby improving the reliability of supporting the plate. Moreover, the second connecting rod 13 can provide support for the first connecting rods 11, improving the reliability of the top material device 100.

[0044] In this embodiment, the first direction and the second direction are two mutually perpendicular directions on a horizontal plane.

[0045] In this embodiment, an auxiliary support component 30 can be provided between every two first connecting rods 11. Except for lacking the lifting drive component 12, the auxiliary support component 30 has the same structure as the lifting component 10, which will not be described in detail here. The auxiliary support component 30 can improve the support capacity of the top material device 100. The auxiliary support component 30 is driven by the lifting drive component 12 and the second connecting rod 13 of the lifting component 10 to achieve lifting.

[0046] like Figure 2As shown, the lifting assembly 10 further includes an auxiliary alignment member 14, the two ends of which are connected to the first connecting rod 11 and the driving end of the lifting drive member 12, respectively. The auxiliary alignment member 14 is used to align the driving end of the lifting drive member 12 with the end of the universal rolling member 22 away from the mounting base 21.

[0047] In this embodiment, the driving end of the lifting drive 12 is aligned with the end of the universal rolling element 22 away from the mounting base 21 by the auxiliary alignment member 14, so that the height of the universal rolling element 22 can be adjusted by adjusting the driving end of the lifting drive 12.

[0048] Furthermore, the auxiliary alignment member 14 includes a first auxiliary plate 141, a second auxiliary plate 142, and a third auxiliary plate 143 connected in sequence. The first auxiliary plate 141 and the second auxiliary plate 142 are arranged vertically, and the first auxiliary plate 141 and the third auxiliary plate 143 are arranged horizontally. The first auxiliary plate 141 is connected to the driving end of the lifting drive member 12, and the third auxiliary plate 143 is connected to the first connecting rod 11.

[0049] In this embodiment, the first connecting rod 11 and the lifting drive component 12 are connected together by the first auxiliary plate 141, the second auxiliary plate 142 and the third auxiliary component, which has a simple structure.

[0050] Furthermore, the first auxiliary plate 141 and / or the third auxiliary plate 143 are slidably disposed along the height direction of the second auxiliary plate 142.

[0051] In this embodiment, after the first connecting rod 11, the rolling support assembly 20, and the lifting drive component 12 are assembled together, when it is necessary to fine-tune the height of the rolling support assembly 20, the height position of the first auxiliary plate 141 and / or the third auxiliary plate 143 on the second auxiliary plate 142 can be adjusted.

[0052] This application also provides a laser cutting device, such as... Figures 1 to 6 As shown, the laser cutting equipment includes: a laser cutting host 200, a fixed auxiliary bed 300, a worktable 400, and a material ejector 100 as described above; the laser cutting host 200 has a feed inlet 210, the fixed auxiliary bed 300 is disposed adjacent to the feed inlet 210, the worktable 400 is slidably disposed on the fixed auxiliary bed 300 and enters and exits the laser cutting host 200 through the feed inlet 210, the material ejector 100 is disposed inside the fixed auxiliary bed 300 and located below the worktable 400, and the worktable 400 is provided with a through groove (not shown) through which the first connecting rod 11 passes.

[0053] The working principle of the laser cutting equipment provided in this application embodiment is as follows: When no material is loaded, the first connecting rod 11 is located below the worktable 400; when loading material, the lifting drive component 12 drives the first connecting rod 11 to move upward and pass through the through slot of the worktable 400. The operator places the plate to be cut on the universal rolling component 22 of the multiple lifting components 10. Then, the lifting drive component 12 drives the first connecting rod 11 to move downward and drives the universal rolling component 22 to move downward. When the universal rolling component 22 is located below the worktable 400, the plate to be cut is placed on the worktable 400, thus completing the loading; then, the worktable 400 enters the laser cutting host 200 through the feed port 210, and the laser cutting host 200 cuts the plate to be cut.

[0054] When the material needs to be adjusted, the lifting drive 12 drives the first connecting rod 11 to move upward and pass through the through slot of the worktable 400. The material to be cut is lifted by the universal rolling element 22, and then the operator adjusts the material to be cut. Subsequently, the lifting drive 12 drives the first connecting rod 11 to move downward and drives the universal rolling element 22 to move downward. When the universal rolling element 22 is below the worktable 400, the material to be cut is placed on the worktable 400, thus completing the adjustment.

[0055] When the position of the rolling support assembly 20 needs to be adjusted to accommodate different sizes of cutting plates, the fixing rod is released to facilitate the movement of the mounting base 21. After the mounting base 21 is moved to the required position, the fixing rod is then fixed together with the first connecting rod 11. When the mounting base 21 is moved, the position of the fixing rod in the waist hole 23 also moves. The size of the waist hole 23 can be set according to actual needs.

[0056] The beneficial effects of the laser cutting equipment provided in this application embodiment are as follows: a rolling support assembly 20 is provided on the first connecting rod 11, and the universal rolling element 22 of the rolling support assembly 20 provides support for the plate, which can prevent scratches from being generated on the back of the plate; in addition, the position of the universal rolling element 22 can be adjusted by the fixing rod, the mounting base 21 and the waist hole 23 to adapt to different sizes of plates to be cut, thereby improving the adaptability and utilization rate of the top material device 100.

[0057] like Figure 5 As shown, the workbench 400 further includes a frame 410 and a plurality of support bars 420. The outer wall of the frame 410 is slidably connected to the fixed auxiliary bed 300. The inner wall of the frame 410 is provided with a slot, and the support bars 420 are engaged with the slot.

[0058] In this embodiment, the support bar 420 is engaged with the slot of the frame 410, and the support bar 420 can be removed from the frame 410 to form a through slot for the first connecting rod 11 to pass through.

[0059] like Figure 6 As shown, there are two worktables 400, which are arranged vertically at intervals along the fixed auxiliary bed 300, and the top material device 100 is located below the lower worktable 400.

[0060] In this embodiment, when no material is being loaded, the first connecting rod 11 is located below the lower worktable 400. When loading material, the lifting drive 12 drives the first connecting rod 11 to move upward and pass through the through slots of the lower worktable 400 and the upper worktable 400. The operator places the plate to be cut on the universal rolling element 22 of the multiple lifting components 10. Then, the lifting drive 12 drives the first connecting rod 11 to move downward and drives the universal rolling element 22 to move downward. When the universal rolling element 22 is located below the lower worktable 400, the plate to be cut is placed on the upper worktable 400, thus completing the loading. Subsequently, the upper worktable 400 enters the laser cutting host 200 through the feed port 210, and the laser cutting host 200 cuts the plate to be cut.

[0061] Next, the lifting drive 12 drives the first connecting rod 11 to move upward and pass through the through slot of the lower worktable 400. The operator places the plate to be cut on the universal rolling parts 22 of the multiple lifting components 10. Then, the lifting drive 12 drives the first connecting rod 11 to move downward and moves the universal rolling parts 22 downward. When the universal rolling parts 22 are below the lower worktable 400, the plate to be cut is placed on the lower worktable 400, thus completing the loading. Subsequently, the upper worktable 400 returns to the fixed auxiliary bed 300 through the feed port 210, while the lower worktable enters the laser cutting host 200 through the feed port 210. The laser cutting host 200 cuts the plate to be cut.

[0062] Next, the lifting drive 12 drives the first connecting rod 11 to move upward and pass through the through slot of the upper worktable 400. The operator places the plate to be cut on the universal rolling element 22 of the multiple lifting components 10. Then, the lifting drive 12 drives the first connecting rod 11 to move downward and drives the universal rolling element 22 to move downward. When the universal rolling element 22 is below the upper worktable 400, the plate to be cut is placed on the upper worktable 400, thus completing the loading. Subsequently, the lower worktable 400 returns to the fixed auxiliary bed 300 through the feed port 210, while the upper worktable enters the laser cutting host 200 through the feed port 210. The laser cutting host 200 cuts the plate to be cut. The cycle repeats.
