[0030] In specific use, the through groove opened at the vertical intersection of the surface of the operation table 2 and the bidirectional screw rod 5 is used to facilitate the movement of the moving plate 7 and limit the movement range of the moving plate 7.

[0031] Preferably, three groups of insertion grooves 11 are longitudinally and equidistantly opened on one side surface of the limiting plate 8, and the shape and size of the insertion groove 11 are matched with the top plate 12.

[0032] In specific use, according to the thickness of the heat-conducting silica gel sheet, the top plate 12 is inserted into the insertion groove 11 of corresponding height opened between the two groups of limiting plates 8, so that the bottom of the top plate 12 abuts against the top of the heat-conducting silica gel sheet.

[0036] In specific use, the second motor 20 is started to rotate, and when the transmission end of the second motor 20 rotates, the gear 19 connected to the surface of the second motor 20 drives the toothed plate 17 meshed at the bottom to move on the limiting frame 18 to one end of the blanking groove 21.

[0037] Preferably, the blanking groove 21 is opened on one side surface of the operation table 2 away from the second motor 20 on the top, and the blanking plate 16 is an "L"-shaped integral structure.

[0038] In specific use, when the cutting assembly 3 is cut to the heat-conducting silica gel sheet, the heat-conducting silica gel sheet is gradually pushed to the opening end region of the blanking plate 16, and the blanking plate 16 is pushed to the blanking groove 21 on the other side by the transverse movement and discharged to the other side along the slope of the blanking groove 21.

[0039] Working principle: when cutting the heat-conducting silicone rubber sheet placed on one side of the operating table 2 with the cutting assembly 3 on the body 1 of the cutting machine, according to the size and thickness of the heat-conducting silicone rubber sheet to be cut, place the heat-conducting silicone rubber sheet on the top of the operating table 2, then start the first motor 6 to drive the connected bidirectional screw rod 5 to rotate in the bearing on the surface of the mounting plate 4, thereby driving the two groups of moving plates 7 on the surface of the bidirectional screw rod 5 to move towards the middle at the same time, thereby making the limiting plates 8 connected to the top of the moving plates 7 move towards the direction of the heat-conducting silicone rubber sheet placed in the middle on the operating table 2, when the limiting plates 8 move, the vertical rods 9 connected to the two sides of the limiting plates 8 slide on the vertical rods 9 on the top of the operating table 2 at the same time, thereby making the limiting plates 8 can move stably and parallel, after the two limiting plates 8 on both sides move and abut against the heat-conducting silicone rubber sheet at the same time, turn off the first motor 6 to make the two groups of moving plates 7 on the bidirectional screw rod 5 connected to it can be stably fixed in place, at this time, according to the thickness of the heat-conducting silicone rubber sheet, insert the top plate 12 into the corresponding height slot 11 between the two limiting plates 8, thereby making the bottom of the top plate 12 abut against the top of the heat-conducting silicone rubber sheet, and then using the limiting plates 8 and the top plate 12 to limit the position of the heat-conducting silicone rubber sheet, to avoid the cutting knife on (3) cutting the heat-conducting silicone rubber sheet due to its good elasticity, causing it to bounce on the operating table 2, thereby affecting the cutting precision of the heat-conducting silicone rubber sheet, and when different batches of heat-conducting silicone rubber sheets of different models need to be cut, repeat the above operation to adjust the distance between the two limiting plates 8, and also need to replace the top plate 12 of the corresponding model according to the size and thickness of the heat-conducting silicone rubber sheet, at this time, start the electric push rod 14 to make the push plate 15 connected to the transmission end of the electric push rod 14 push the heat-conducting silicone rubber sheet placed between the limiting plates 8 and the top plate 12;

[0040] At the same time, the cutting assembly 3 cuts the heat-conducting silicone rubber sheet pushed by the user according to the user's settings. After the first cutting is completed, the electric push rod 14 pushes the push plate 15 connected to the transmission end again to push the abutting heat-conducting silicone rubber sheet according to the user's settings. When the push plate 15 pushes the heat-conducting silicone rubber sheet, the front end of the heat-conducting silicone rubber sheet is pushed out of the cutting area at the bottom of the cutting assembly 3 by the abutting heat-conducting silicone rubber sheet that has not been cut. At this time, the second motor 20 can be started to rotate. When the transmission end of the second motor 20 rotates, the gear 19 connected to the surface of the second motor 20 drives the bottom meshing tooth plate 17 to move to one end of the discharge chute 21 on the limiting frame 18. When the cutting area at the bottom of the cutting assembly 3 is gradually pushed by the heat-conducting silicone rubber sheet that has been cut, the discharge chute 21 at the other side is pushed by the horizontally moving discharge chute 16, and the heat-conducting silicone rubber sheet is discharged to the other side along the slope of the discharge chute 21. At this time, a collection container can be placed beside the discharge chute 21 to receive the cut heat-conducting silicone rubber sheet, so as to timely discharge the cut heat-conducting silicone rubber sheet, avoid stacking in the cutting area, affect the cleanliness of the area, and avoid mis-cutting the heat-conducting silicone rubber sheet product.

[0041] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
