[0024] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used herein in the specification are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0026] Combination Figs. 1-3 As shown, a cutting device for producing heat-conducting gaskets, comprising:

[0027] The base 1 is set as a rectangular bottom support structure, and the top thereof is provided with a lifting seat 2 for lifting adjustment;

[0028] The cutting assembly 3 is arranged on the top surface of the lifting seat 2, and the bottom thereof is provided with a cutter 33, which extends vertically downward to the bottom of the lifting seat 2, for cutting the heat-conducting gasket;

[0029] The conveying belt 5 is arranged on the top of the base 1, and the surface thereof is provided with a fixed seat 51 for placing and fixing the heat-conducting gasket, and the conveying belt 5 transversely passes through the top surface of the base 1, and the fixed seat 51 on the top surface thereof is sequentially aligned with the cutting assembly 3 upward and downward, thereby assisting in completing the cutting work;

[0030] The adjusting assembly 4 is arranged on the top of the cutting assembly 3 and is in transmission connection with the cutting assembly 3. The purpose is to change the distance between the cutters through the threaded transmission, that is, to change the width of the cut heat-conducting gasket, so as to improve the application range of the equipment.

[0031] Specifically, in the embodiment, the lifting seat 2 is composed of a horizontally arranged rectangular plate and four air cylinders. The four air cylinders are arranged at the four corners of the rectangular plate and are fixed on the bottom surface of the base 1. The four air cylinders are electric air cylinders that can be synchronously driven (or electric telescopic rods can be used instead). The rectangular plate is arranged just above the conveying belt 5, so that the cutter 33 is aligned downward to the heat-conducting gasket on the conveying belt 5.

[0032] The cutting assembly 3 includes a chute 31 arranged transversely on the top surface of the lifting seat 2. The chute 31 is provided with a mounting seat 32. The bottom of the mounting seat 32 penetrates through the chute 31 and extends below the partition plate. The bottom surface of the mounting seat 32 is also provided with an opening in the longitudinal direction. The cutter 33 is fixedly installed in the opening and is fixed by bolts.

[0033] Therefore, in the embodiment, the up-down telescopic movement of the air cylinder is mainly controlled, so that the cutter 33 can move up and down continuously to cut the heat-conducting gasket.

[0034] In addition, the air cylinder can be replaced by a support column with a groove structure. The support column is telescoped at the top by the air cylinder, and the cutting assembly 3 can also be controlled.

[0035] In actual production, the heat-conducting gasket to be produced is generally produced in large quantities. Therefore, in the above structure, the mounting seat 32 of the cutting assembly 3 is arranged in multiple intervals, that is, the cutter 33 is also arranged in multiple. The purpose is to cut the whole heat-conducting gasket by using multiple cutters 33 through one-time up-down cutting. Therefore, the distance between every two adjacent cutters 33 should be equal, and the distance is equal to the width of the cut heat-conducting gasket.

[0036] However, the heat-conducting gasket to be produced has various sizes. Therefore, the distance between the adjacent cutters needs to be adjusted during the production change. The conventional manual adjustment is slow and needs to stop the machine, which affects the continuous production efficiency of the equipment. Therefore, the adjusting assembly 4 is used to adjust the distance between the cutters, so that the distance between the adjacent cutters 33 can still be equal.

[0037] Based on the above requirements, the adjusting assembly 4 comprises a screw rod 41 rotatably mounted in the sliding groove 31, and a plurality of thread segments are arranged on the screw rod 41, the specific number of which should be arranged according to the number of required tools, and the end surface of each mounting seat 32 is provided with a threaded hole, and the above threaded segments are movably assembled, so that the staff can drive the horizontal displacement of the mounting seat 32 by driving the screw rod 41.

[0038] In the above structure, the pitches of the plurality of thread segments are different, gradually increasing from one end to the other end, so the internal pitches of the threaded holes on the plurality of mounting seats 32 should also be adjusted accordingly, and the moving distances of the plurality of mounting seats 32 are fixed ratios at the same rotating speed, for example, the fixed ratio of the moving distances of the three mounting seats 32 in the drawing is 1:2:3:4, so that each two adjacent tools can still maintain the same spacing after adjusting the tool position.

[0039] Moreover, in the above structure, a servo motor 42 should also be arranged on one side of the lifting seat 2, and the output end of the servo motor 42 is drivingly connected with one end of the screw rod 41, thereby realizing remote operation, so that the spacing adjustment of the tools can be completed without stopping the whole device, realizing the online adjustment function, and greatly improving the convenience of tool adjustment.

[0040] During actual use, the cutting knife 33 is easy to completely cut the cutting part due to the elasticity of the heat-conducting gasket, thereby affecting the cutting precision, so the retractable plates 34 should also be arranged on both sides of the cutting knife 33, which are composed of two rectangular plates slidingly connected with each other, and a spring is arranged in the upper rectangular plate, and the bottom rectangular plate will shrink inward when being pressed, thereby compacting the two sides of the cutting knife 33 and avoiding the bending of the heat-conducting gasket at the cutting position.

[0041] Moreover, after long-term use, the cutting knife 33 will inevitably leave some residues on the surface, which will affect the normal use of the subsequent cutting knife 33, so the scraper 35 should also be horizontally arranged at the bottom of the retractable plate 34, and the opposite side of the two scrapers 35 should be provided with an arc-shaped elastic piece, so that it can retain a certain gap, the cutting knife 33 can pass through the gap and extend downward to complete cutting, and the positioning area during pressing can be enlarged, which is very convenient to use. In the natural state, the tool is retracted between the two elastic plates, which can also protect the workers during disassembly and assembly, avoiding scratches.

[0042] The base 1 is also equipped with a counter 6, which is an infrared automatic induction counting device of a pipeline CU-62PB-N, and the detection end thereof is arranged towards the side of the conveying belt 5, and each time a fixed seat 51 passes the detection end, it is recorded, so as to facilitate the staff to count the daily workload, and the display screen on the main surface thereof is used for display.

[0043] In the cutting process, in order to ensure that the heat-conducting gasket and the protective film attached to the surface thereof can be completely cut off, the bottom of the cutter 33 is in contact with the top surface of the fixed seat 51 when the cutter 33 cuts downward, and in order to avoid the blade of the cutter 33 being prematurely blunt, a pad foam should be arranged on the top surface of the fixed seat 51.

[0044] The side wall of the lifting seat 2 is also provided with a mark scale, and a triangular pointer is correspondingly arranged on the side wall of the mounting seat 32, so as to facilitate the staff to observe the actual distance between the cutters.

[0045] Finally, it should be pointed out that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present application.
