[0034] The utility model will be further explained in connection with the drawings and specific embodiments.

[0035] As Figure 1 shown, an electrical cabinet support beam outer surface protection film mounting device, including support frame 1, press film mechanism and at least two limiting modules.

[0036] One end of support frame 1 is feed end 2, and the other end is discharge end 3.

[0037] The press film mechanism is arranged at the discharge end of the support frame 1, and the press film mechanism includes a lower pressing film roller 4, two frame bodies 5, an upper pressing film roller 6, and two adjusting members.

[0038] The lower pressing film roller 4 is horizontally and rotationally arranged on the discharge end 3 of the support frame 1, and is perpendicular to the direction of the sheet conveying; two frame bodies 5 are vertically fixed on both sides of the discharge end 3 of the support frame 1; two adjusting members each include a sliding block 7 and a first lead screw 8; the sliding block 7 is vertically slidably arranged in the frame body 5; the first lead screw 8 is threadedly connected to the top of the frame body 5, and the bottom of the first lead screw 8 penetrates through the top of the frame body 5 downward; the bottom of the first lead screw 8 is rotationally connected to the top of the sliding block 7.

[0039] At least two limiting modules each include a pair of limiting wheels 9; each pair of limiting wheels 9 is horizontally and rotationally arranged on both sides of the support frame 1 to limit the sheet to be edge folded during conveying. In the present embodiment, the number of limiting modules is two.

[0040] Furthermore, in this embodiment, the limiting module further includes a second lead screw 10, which is horizontally and rotatably mounted on the support frame 1 and parallel to the lower pressure roller 4. Guide rods 11 are provided on both sides of the second lead screw 10 on the support frame 1. Each limiting wheel 9 has a support block 12 at its bottom, and two support blocks 12 are threaded onto the second lead screw 10 and are symmetrically arranged. In a pair of limiting wheels 9, the internal threads of the through holes connected to the support blocks 12 and the second lead screw 10 are opposite in direction. The support blocks 12 are slidably mounted on the two guide rods 11. With this configuration, by rotating the second lead screw 10, the distance between the two limiting wheels 9 can be quickly adjusted to accommodate thin plates of different widths and effectively limit the thin plates during transmission.

[0041] In this embodiment, both the end of the first lead screw 8 and the end of the second lead screw 10 are provided with handles 13 to facilitate operation by staff.

[0042] In this embodiment, both sides of the feed end 2 of the support frame 1 are provided with arc-shaped guide plates 14, and a number of guide rollers 15 are provided at equal intervals between the two arc-shaped guide plates 14 along their arc direction, so as to facilitate the pulling of the protective film on the external unwinding device and attach it to the lower surface of the thin plate.

[0043] Furthermore, a pre-pressing component is provided on the support frame 1 at the rear end of the arc-shaped guide plate 14. The pre-pressing component includes a lower pre-pressing roller 16 and an upper pre-pressing roller 17. The upper pre-pressing roller 17 and the lower pre-pressing roller 16 are horizontally rotatably arranged on the support frame 1, one above the other. The surfaces of the upper pre-pressing roller 17 and the lower pre-pressing roller 16 are covered with a foam layer (not shown in the figure). With this arrangement, the protective film is pre-pressed onto the lower surface of the thin plate, and the elasticity of the foam layer is utilized to achieve a better pre-pressing effect.

[0044] In this embodiment, a pressure roller 18 is provided between two adjacent limiting modules to prevent the thin plate from bulging during the conveying process and to facilitate subsequent film pressing.

[0045] like Figure 2 As shown, by rotating the second lead screw 10 and the first lead screw 9, the distance between the two limit wheels 9 in the limit module and the distance between the upper pressure roller 6 and the lower pressure roller 4 are adjusted. Then, when the thin plate to be folded is conveyed, the thin plate and the protective film on the unwinding device pass through the feed end 2 of the support frame 1 at the same time. The thin plate is located above the protective film. The protective film enters the feed end 2 of the support frame 1 under the guidance of the guide roller 15 on the arc guide plate 14. Under the action of a pair of pre-pressing components, the protective film is initially attached to the lower surface of the thin plate. Then, under the action of the limit module and the pressure roller 18, it is conveyed to the pressing mechanism. The upper pressure roller 6 cooperates with the lower pressure roller 4 to press the protective film onto the lower surface of the thin plate.

[0046] The inventor needs to explain that the lower surface of the sheet will become the outer surface of the support beam after being folded in the subsequent sheet folding process.
