[0034] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0035] Embodiment

[0036] As Figure 3 shown, the limiting device for on-line conveying of the raw material roll of the border strip for the condenser in this embodiment includes a conveying mechanism and a limiting mechanism.

[0037] As Figure 1 shown, the conveying mechanism includes a frame 1, a pair of pressure rollers, and a driving mechanism.

[0038] The pair of pressure rollers includes a lower pressure roller 2 and an upper pressure roller 3; the lower pressure roller 2 is horizontally rotatably arranged at the lower part inside the frame 1, and first gears 4 are arranged at both ends of the lower pressure roller 2, and one end of the lower pressure roller 2 is connected to a driving motor 5.

[0039] A support frame 6 is vertically slidably arranged in the frame 1 directly above the lower pressure roller 2, the upper pressure roller 3 is horizontally rotatably arranged inside the support frame 6, the upper pressure roller 3 is directly above the lower pressure roller 2, and second gears 7 are arranged at both ends of the upper pressure roller 3, and the second gears 7 are adapted to the first gears 4.

[0040] The driving device is a cylinder 8, which is arranged at the top of the frame 1 and is used to drive the support frame 6 to move vertically within the frame 1. In this embodiment, the number of the cylinders 8 is two, and the two cylinders 8 are respectively arranged at both ends of the top of the frame 1. The piston rod of the cylinder 8 vertically penetrates the top of the frame 1 and is connected to the top of the support frame 6. With such an arrangement, it effectively avoids the shaking of the support frame 6 during movement. Additionally, after the support frame 6 moves to a suitable position, its stability at the suitable position is improved.

[0041] In this embodiment, a support rod 9 is vertically fixed upward at the middle position of the top of the support frame 6. The support rod 9 penetrates the top of the frame 1. A stop block 10 is fixed at the top of the support rod 9. A spring 11 is sleeved on the support rod 9 between the stop block 10 and the top of the frame 1. With such an arrangement, when the air in the cylinder 8 is released, under the action of the elastic force of the spring 11, the support frame 6 quickly rises, facilitating the staff to pass the border strip roll to be punched through.

[0042] As Figure 3 shown, the limiting mechanism includes a workbench 12 and two limiting blocks 13. The workbench 12 is arranged on one side of the discharge end of the frame 1. The two limiting blocks 13 are fixed on the workbench 12 one after the other along the conveying direction of the raw material roll, and the distance between the two limiting blocks 13 is adapted to the mold to be placed.

[0043] At least one pair of limiting rods 14 are vertically fixed on both of the two limiting blocks 13. The distance between the same group of limiting rods 14 is adapted to the width of the raw material roll to be punched. With such an arrangement, the raw material roll is effectively limited, facilitating subsequent precise punching. In this embodiment, there are two pairs of limiting rods 14 on each limiting block 13.

[0044] In this embodiment, as Figure 4 shown, on the workbench 12, blanking modules are arranged on both sides of the two limiting blocks 13. The blanking module includes a support block 15, a blanking block 16 and a screw rod 17. The support block 15 is fixed on the workbench 12. One end of the blanking block 16 is hinged to the support block 15. A waist-shaped through hole 18 is arranged on the blanking block 16 along its length direction, and the waist-shaped through hole 18 penetrates the upper and lower surfaces of the blanking block 16. The screw rod 17 is vertically and threadedly connected to the workbench 12 and passes through the waist-shaped through hole 18. A nut 19 is arranged on the upper part of the screw rod 17. With such an arrangement, after the mold is inserted between the two limiting blocks 13, the blanking block 16 is rotated, the screw rod 17 is passed through the waist-shaped through hole 18 and threadedly connected to the workbench 12, and the nut 19 is tightened, then the mold can be effectively fixed.

[0045] In this embodiment, a support plate 20 is horizontally fixed at the discharge end of the frame 1. The support plate 20 is flush with the top of the lower pressing roller 2. A height limiting plate 21 is fixed on the support plate 20. The height limiting plate 21 is horizontally arranged, and a gap is left between the height limiting plate 21 and the support plate 20 for the raw material roll to pass through.

[0046] In this embodiment, a plurality of guide rollers 22 are horizontally arranged on one side of the feed end of the frame 1 to facilitate guiding the raw material roll into the space between the upper / lower pressing rollers.

[0047] When transporting the raw material roll, first lift the support frame 6 through the cylinder 8. The worker passes the raw material roll through the gap between the upper and lower pressing rollers, and then passes the roll through the gap between the height limiting plate 21 and the support plate 20 and into the space between a pair of limiting rods 14 on the limiting block 13. Then start the cylinder 8 to lower the support frame 6 so that the gears at both ends of the upper and lower pressing rollers mesh with each other. Start the drive motor 5, and the lower pressing roller 2 rotates to convey the raw material roll forward. Insert a mold between the two limiting blocks 13. When the end of the raw material roll reaches the specified position on the mold, the external punching head punches downward to punch the raw material roll into a border strip with a fixed length and an end conforming to the specified shape. The rotation speed of the drive motor 5 can be set to control the conveying speed of the raw material roll. The drive motor can be signal-connected to the stamping equipment. When the stamping equipment punches, the drive motor stops running.

[0048] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
