The support columns are fixed to the chassis below, and the anti-slip pads are installed below the chassis;

[0004] The prior art fixes the two ends of the silica gel sheet stably through the setting of the fixing mechanism, so as to effectively prevent the silica gel sheet from displacing during the slitting process; by setting the slitting mechanism, the slitting knife and the mounting seat are connected and fixed together through fixing bolts and fixing nuts, so that it is convenient to disassemble and replace the slitting knife; based on the retrieval of the above patent and the combination of the equipment in the prior art, it is found that when the above equipment is applied, the distances between several slitting knives are the same, and the distance between the slitting knives cannot be freely adjusted. Therefore, in actual use, it can only be used for the slitting work of silica gel sheets of one size and cannot be applied to the slitting of silica gel sheets of different sizes, which has certain limitations in use. For this reason, the utility model proposes a slitter for heat-conducting silica gel sheets that can freely adjust the distance between the slitting knives. Summary of the Utility Model

[0026] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a slitting machine for thermal conductive silicone sheets, including a cabinet 1. A slitting table 2 is arranged on the upper surface of the cabinet 1. The slitting table 2 can be used to place the thermal conductive silicone sheets to be slit. Support columns 3 are fixedly installed at the four corners of the upper surface of the slitting table 2. The tops of the four support columns 3 are fixedly installed with a top plate 4. A driving cylinder 5 is fixedly installed at the center position of the upper surface of the top plate 4. The driving cylinder 5 is one of a pneumatic cylinder or a hydraulic cylinder. The output end of the driving cylinder 5 is movably connected with a driving rod 6. The bottom end of the driving rod 6 is fixedly installed with a lower mounting plate 7;

[0027] With this structural design, the driving cylinder 5 provided can drive the lower mounting plate 7 to move up and down through the driving rod 6, so as to meet the slitting down and lifting effects;

[0028] Among them, specifically, please refer to the attached Figure 2 and Figure 3 shown. Guide rails 8 are fixedly installed on both sides of the lower surface of the lower mounting plate 7. The guide rails 8 adopt an "I"-shaped structural design. A plurality of slitting mechanisms are slidably connected to the guide rails 8. The slitting mechanism includes two sets of sliding members 9. The two sets of sliding members 9 are respectively slidably connected to the guide rails 8 on both sides. Lower support plates 10 are fixedly installed on both sides of the lower surface of the sliding members 9. A tool mounting rack 11 is fixedly installed between the lower support plates 10 of the two sliding members 9. A slitting knife 12 is installed on the lower surface of the tool mounting rack 11. A positioning bolt 13 is threadedly connected at the bottom end of the sliding member 9 and between the two lower support plates 10;

[0029] In this structural design, when it is necessary to install a single slitting mechanism, it can be slid onto the guide rail 8 through the sliding parts 9 on both sides, and then the positioning bolts 13 are tightened for positioning work. After tightening, the positioning bolts 13 can be in close contact with the lower surface of the guide rail 8, so that the installation work of the slitting structure can be completed. In this utility model, several slitting mechanisms are installed on the guide rail 8, as specifically shown in the attached Figure 2 description, so that the silicone sheets of specified dimensions can be slit by adjacent slitting mechanisms;

[0030] When it is necessary to adjust the slitting size of the silicone sheet, the slitting size can be freely adjusted by adjusting the distance between the two slitting mechanisms at this time;

[0031] Since several slitting mechanisms are all slidably installed on the guide rail 8 through the sliding parts 9, during adjustment, loosen the positioning bolts 13 on the two slitting mechanisms, so that the slitting mechanisms can freely slide on the guide rail 8 through the sliding parts 9, thereby adjusting the distance between the two slitting knives 12. When the distance value between the slitting knives 12 of the slitting mechanism reaches the specified slitting size, then tighten the positioning bolts 13 to complete the fixing work between the two slitting structures, so that the distance between the slitting mechanisms can be adjusted by the sliding adjustment method. In actual use, the slitting size of the slitting machine of this utility model can be freely adjusted, which can meet the production requirements of different slitting size requirements, thereby greatly improving the application range of this utility model. Through the dynamic adjustability of the slitting size, the use limitations can be effectively reduced, and it has a good use effect.

[0032] In this embodiment, in order to facilitate the pressing of both sides of the silicone sheet material, side columns 21 are fixedly installed on the outer surfaces at both ends of the slitting table 2. A telescopic column 14 is slidably connected inside the side column 21, so that the telescopic column 14 can telescopically slide inside the side column 21;

[0033] Among them, positioning holes 15 are provided on both the side column 21 and the telescopic column 14. The positioning holes 15 are provided with fixing bolts adapted to their hole diameters. When it is necessary to fix the telescopic column 14, the positioning holes 15 of the telescopic column 14 can be aligned with the positioning holes 15 of the side column 21, and then the fixing bolts can be screwed into the positioning holes 15, so as to complete the positioning work of the telescopic column 14, thereby fixing and limiting the overall length of the column body;

[0034] Furthermore, two telescopic columns 14 on the same side are vertically and fixedly installed with side plates 16 at the top. A secondary plate 17 is fixedly installed on the inner wall at the top of the side plate 16. The side plate 16 and the secondary plate 17 are perpendicular to each other;

[0035] Furthermore, a pressing stud 18 is internally threadedly connected to the top end of the secondary plate 17. The bottom end of the pressing stud 18 is rotatably connected to a lower pressing plate 19 through a bearing. A silica gel pad 20 is adhesively attached to the bottom surface of the bottom end of the lower pressing plate 19 by glue;

[0036] According to the above structure, when it is necessary to press and fix the side of the silica gel sheet, the silica gel sheet can be placed below the lower pressing plates 19 on both sides at this time. At this time, the pressing stud 18 can be manually rotated. When the pressing stud 18 rotates, it will drive the lower pressing plate 19 at its bottom end to descend, so that the silica gel sheet below can be pressed through the descent of the lower pressing plate 19, completing the side fixing effect of the silica gel sheet, preventing it from moving during the slitting process, and improving the slitting quality;

[0037] Moreover, the distance between the two lower pressing plates 19 can be adjusted by the expansion and contraction of the telescopic column 14, so as to complete the pressing and limiting work on silica gel sheets of different lengths and sizes, improving the overall use effect and scope of use, and having good practicability.

[0038] In this embodiment, in order to seal and repair the electrical components inside the cabinet 1, a sealing door 22 is hingedly connected to the outer surface of the front of the cabinet 1. A handle is installed on the sealing door 22, and support legs are fixedly installed at the four corners of the bottom end of the cabinet 1.

[0039] Working principle: When it is necessary to slit the heat-conducting silica gel sheet, the silica gel sheet can be placed below the lower pressing plates 19 on both sides at this time. At this time, the pressing stud 18 can be manually rotated. When the pressing stud 18 rotates, it will drive the lower pressing plate 19 at its bottom end to descend, so that the silica gel sheet below can be pressed through the descent of the lower pressing plate 19, completing the side fixing effect of the silica gel sheet, preventing it from moving during the slitting process, and improving the slitting quality;

[0040] Moreover, the distance between the two lower pressing plates 19 can be adjusted by the expansion and contraction of the telescopic column 14, so as to complete the pressing and limiting work on silica gel sheets of different lengths and sizes, improving the overall use effect and scope of use, and having good practicability;

[0041] After the silica gel sheet is fixed, the driving cylinder 5 works. Through the arranged driving cylinder 5, the lower mounting plate 7 can be driven to descend by the driving rod 6. When the lower mounting plate 7 descends, the slitting knives 12 of several slitting mechanisms are driven to descend, so as to complete the slitting work on the silica gel sheet through several slitting knives 12;

[0042] After slitting is completed, the driving cylinder block 5 drives the slitting knife 12 on the lower mounting plate 7 to rise through the driving rod 6, and then drives the lower pressing plate 19 to rise through the rotating pressing stud 18, so as to release the pressing state of the silica gel sheet. At this time, the slit silica gel sheet is taken off, and a new silica gel sheet is put in and the slitting processing work is cycled in the above manner;

[0043] When the present utility model needs to install a single slitting mechanism, it can be slid into the guide rail 8 through the sliding members 9 on both sides, and then the positioning bolts 13 are tightened for positioning work. After tightening, the positioning bolts 13 can be in close contact with the lower surface of the guide rail 8, so as to complete the installation work of the slitting structure. The present utility model installs several slitting mechanisms on the guide rail 8, as specifically shown in the attached Figure 2 description, so that the silica gel sheet can be slit into specified sizes by adjacent slitting mechanisms;

[0044] When it is necessary to adjust the slitting size of the silica gel sheet, the slitting size can be freely adjusted by adjusting the distance between the two slitting mechanisms at this time;

[0045] Since several slitting mechanisms are all slidably installed on the guide rail 8 through the sliding members 9, during adjustment, the positioning bolts 13 on the two slitting mechanisms are loosened, so that the slitting mechanisms can freely slide on the guide rail 8 through the sliding members 9, thereby adjusting the distance between the two slitting knives 12. When the distance value between the slitting knives 12 of the slitting mechanism reaches the specified slitting size, the positioning bolts 13 are tightened at this time to complete the fixing work between the two slitting structures, so that the distance between the slitting mechanisms can be adjusted by the sliding adjustment method. In actual use, the slitting size of the slitting machine of the present utility model can be freely adjusted, which can meet the production requirements of different slitting size requirements, thereby greatly improving the applicable range of the present utility model. Through the dynamic adjustable slitting size, the use limitation can be effectively reduced, and it has a good use effect.

[0046] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
