[0042] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a sealing gasket cutting device, including a fixed frame 100, an outer ring frame 200, and an inner ring frame 300; one end of the fixed frame 100 is fixed to the gasket material, the fixed frame 100 extends in any direction, and the other end of the fixed frame 100 can rotate around the fixed end of the fixed frame 100; one end of the outer ring frame 200 is provided with a first cutting blade group 400, and the inner ring frame 300 is slidably disposed on the fixed frame 100 along the extending direction of the fixed frame 100, so that the first cutting blade group 400 can approach or move away from the fixed end of the fixed frame 100; one end of the inner ring frame 300 is provided with a second cutting blade group 500, and the inner ring frame 300 is slidably disposed on the outer ring frame 200 along the extending direction of the outer ring frame 200, so that the second cutting blade group 500 can approach or move away from the fixed end of the fixed frame 100, and the second cutting blade group 500 and the first cutting blade group 400 are spaced apart.

[0044] That is, the sealing gasket cutting device provided in this embodiment of the utility model rotates the fixed frame 100, thereby driving the inner ring frame 300 and the outer ring frame 200 to rotate accordingly. This causes the first cutting blade group 400 and the second cutting blade group 500, which are fixed on the outer ring frame 200 and the inner ring frame 300, to rotate accordingly, cutting the gasket material to form a sealing gasket. Then, by sliding the inner ring frame 300 and the outer ring frame 200 relative to the fixed frame 100, the distance between the cutting blade group and the fixed end of the fixed frame 100 is adjusted, thereby adjusting the size of the sealing gasket after cutting. This solves the technical problems of existing sealing gasket cutting devices, which have complex structures, are difficult to adjust the size of the sealing gasket, and are difficult to adapt to the actual needs of maintenance work. The device has a simple structure, is easy to disassemble and carry, has low cost, and effectively enhances the speed of on-site production of rubber sealing gaskets.

[0045] Specifically, the fixed frame 100, inner ring frame 300, and outer ring frame 200 are made of 1mm thick iron plate or non-bending stainless steel to ensure sufficient strength. The fixed frame 100 is elongated with a square cross-section, allowing it to fit snugly against the rubber pad material plate. In this embodiment, the outer ring frame 200 is located on one side of the fixed frame 100, and is also approximately elongated. The outer ring frame 200 can be mounted on the fixed frame 100 using structures such as sliding blocks or guide rails, allowing it to slide relative to the fixed frame 100. The first cutting blade assembly 400 is fixed to the end of the outer ring frame 200 away from the fixed end of the fixed frame 100 by bolts or welding. This allows the first cutting blade assembly 400 to rotate with the fixed frame 100, and when the fixed frame 100 rotates one revolution, the outer ring of the sealing rubber pad can be cut into the rubber pad material plate. Simultaneously, by sliding the outer ring frame 200 along the fixed frame 100, the distance between the first cutting blade assembly 400 and the fixed end of the fixed frame 100 can be adjusted, thereby adjusting the outer ring size of the sealing gasket. The inner ring frame 300 is located on the other side of the outer ring frame 200, and its overall shape is also approximately elongated. The inner ring frame 300 can be mounted on the outer ring frame 200 using structures such as sliding groove sliders and guide rail sliders. This allows the inner ring frame 300 to slide relative to the outer frame, and thus relative to the fixed frame 100. The second cutting blade assembly 500 is fixed to the end of the inner ring frame 300 away from the fixed end of the fixed frame 100 by bolts or welding. This allows the second cutting blade assembly 500 to rotate with the fixed frame 100. When the fixed frame 100 rotates one revolution, the inner ring of the sealing gasket can be cut from the gasket material plate, working in conjunction with the first cutting blade assembly 400 to cut a complete sealing ring. At the same time, by sliding the outer ring frame 200 along the fixed frame 100, the distance between the second cutting blade group 500 and the fixed end of the fixed frame 100 can be adjusted, thereby adjusting the inner ring size of the sealing gasket and thus completing the adjustment of the sealing gasket size.

[0046] Furthermore, the sealing gasket cutting device also includes a first locking bolt 230 and a first locking nut. The fixed frame 100 is provided with a first sliding groove 110, and the outer ring frame 200 is provided with a second sliding groove 210. The first locking bolt 230 passes through the second sliding groove 210 and the first sliding groove 110 and is connected to the first locking nut. The first locking bolt 230 can slide along the first sliding groove 110 or the second sliding groove 210.

[0047] Specifically, the first sliding groove 110 is located in the middle of the fixed frame 100 and is a straight elongated slot along the extending direction of the fixed frame 100. The second sliding groove 210 is located in the middle of the outer ring frame 200 and is a straight elongated slot along the extending direction of the outer ring frame 200. The first locking bolt 230 is specifically a hand-tightened winged nut bolt, which passes through the second sliding groove 210 and the first sliding groove 110 and connects to the first locking nut. Thus, after adjusting the position of the outer ring frame 200, the fixed frame 100 and the outer ring frame 200 can be fixed to each other by the first locking bolt 230 to ensure the stability of the outer ring dimension when rotating and cutting the sealing gasket.

[0048] Furthermore, the sealing gasket cutting device also includes a second locking bolt and a second locking nut 330. The inner ring frame 300 is provided with a through hole 310. The second locking bolt passes through the through hole 310, the second sliding groove 210 and the first sliding groove 110 and connects with the second locking nut 330.

[0049] Specifically, the through hole 310 extends horizontally through the inner ring frame 300 from the side away from the outer ring frame 200. In this embodiment, the inner ring frame 300 is provided with two circular through holes 310. The second locking bolt is specifically configured as a hand-tightening winged nut bolt, which can pass through the through hole 310, the second sliding groove 210, and the first sliding groove 110 to connect with the second locking nut 330. Thus, after adjusting the position of the inner ring frame 300, the inner ring frame 300, the outer ring frame 200, and the fixed frame 100 can be fixed together by the second locking bolt to ensure the stability of the inner ring size when rotating and cutting the sealing gasket.

[0050] Preferably, the fixed frame 100 is provided with a scale groove 140 along its extension direction.

[0051] Specifically, the scale groove 140 is provided on the fixed frame 100, extending from the fixed end of the fixed frame 100 to the other end of the fixed frame 100, so as to facilitate the user to make a reference when adjusting the cutting blade assembly and ensure the cutting accuracy of the sealing ring.

[0052] like Figure 3 and Figure 4 As shown, the outer ring frame 200 further includes a first sliding arm 240 and a first mounting arm 250 arranged perpendicularly to each other. A second sliding groove 210 is disposed on the first sliding arm 240. The first sliding arm 240 is arranged parallel to the fixed frame 100. The first cutting blade assembly 400 is fixed to the first mounting arm 250. The inner ring frame 300 includes a second sliding arm 340 and a second mounting arm 350 arranged perpendicularly to each other. A through hole 310 is disposed on the second sliding arm 340. The second sliding arm 340 is arranged parallel to the first sliding arm 240. The second cutting blade assembly 500 is fixed to the second mounting arm 350.

[0053] Specifically, both the inner ring frame 300 and the outer ring frame 200 are L-shaped. The first sliding arm 240 and the second sliding arm 340 are both arranged parallel to the fixed frame 100. The first mounting arm 250 and the second mounting arm 350 are respectively welded perpendicularly to the first sliding arm 240 and the second sliding arm 340. This allows the first mounting arm 250 and the second mounting arm 350 to be arranged perpendicular to the outer ring frame 200, thereby ensuring that the first cutting blade group 400 and the second cutting blade group 500 will not interfere with each other when the inner ring frame 300 and the outer ring frame 200 slide relative to the fixed frame 100.

[0054] Furthermore, the first cutting blade assembly 400 includes a tool mounting bracket 410 and a cutting blade 420. The tool mounting bracket 410 is provided with a mounting block 411, and the cutting blade 420 is fixed to the tool mounting bracket 410. The second cutting blade assembly 500 includes a tool mounting bracket 410 and a cutting blade 420. The tool mounting bracket 410 is provided with a mounting block 411, and the cutting blade 420 is fixed to the tool mounting bracket 410.

[0055] Specifically, the first cutting blade assembly 400 and the second cutting blade assembly 500 have the same structure. The blade mounting bracket 410 has two round holes, allowing the mounting bolts to be connected to the mounting arm bolts of the inner ring frame 300 or the outer ring frame 200. The mounting block 411 protrudes from the plane of the blade mounting bracket 410 and is rectangular in shape. The cutting blade 420 has a rectangular slot, which engages with the mounting block 411, allowing the cutting blade 420 to be engaged with the blade mounting bracket 410. In this embodiment, the cutting blade 420 is a No. 23 surgical blade, and the blade mounting bracket 410 is a No. 4 surgical blade holder, with the two models matching each other. In other embodiments of this application, other models or types of blades and blade mounting brackets 410 can also be selected.

[0056] Preferably, the cutting blade 420 has its cutting edge set at an angle of 30° to 45° to the horizontal direction.

[0057] Specifically, to ensure that the cutting blade 420 can smoothly cut the rubber pad material sheet, the cutting edge of the cutting blade 420 is set at an angle of 30° to 45° with the horizontal direction. In this embodiment, the cutting edge of the cutting blade 420 is selected at 37°. If the cutting edge angle of the cutting blade 420 needs to be adjusted, the position of the opening on the mounting arm can be changed or the fixing angle of the tool mounting bracket 410 can be adjusted before welding the tool mounting bracket 410.

[0058] like Figure 5 and Figure 6As shown, the sealing gasket cutting device further includes a fixed end handle 600. The fixed end of the fixed bracket is provided with a fixed hole 120 in the vertical direction. The fixed end handle 600 is provided with a cone 610, which can pass through the fixed hole 120 to pierce the gasket material.

[0059] Specifically, the fixed end of the fixing bracket has a fixing hole 120 in the vertical direction, and the fixing hole 120 has a circular cross-section. The top of the fixing end handle 600 has a round head, which is held by the user with square edges. The round head can be made of plastic. The bottom of the fixing end handle 600 has a rotating rod that extends into the fixing hole 120. A cone 610 is located at the bottom of the rotating rod, which is simply oriented downwards to facilitate piercing the rubber pad material. In this embodiment, both the rotating rod and the cone 610 are made of metal. By passing the fixing end handle 600 through the fixing hole 120 and piercing the rubber pad material, the fixing end of the fixing bracket can be fixed to the rubber pad material, ensuring that the fixing bracket can rotate around the rotating rod of the fixing end handle 600, which is convenient for the user to operate and cut.

[0060] Furthermore, the sealing gasket cutting device also includes a movable end handle 700, the movable end of the fixed bracket is provided with a rotating hole 130 in the vertical direction, and the bottom of the movable end handle 700 is provided with a rotating shaft 710, which is rotatably disposed in the rotating hole 130.

[0061] Specifically, the movable end of the fixed bracket has a rotating hole 130 in the vertical direction, and the rotating hole 130 has a circular cross-section. The top of the movable end handle 700 has a rounded head, which is held by the user and can be made of plastic. The bottom of the movable end handle 700 has a pivot 710 that extends into the rotating hole 130. When it is necessary to rotate the fixed bracket, simply hold the rounded head of the movable end handle 700 and rotate the movable end of the fixed bracket. At this time, the pivot 710 at the bottom of the movable end handle 700 will rotate in the rotating hole 130, avoiding the rounded head of the movable end handle 700 being rotated by the user, making it convenient and flexible.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
