Description

Technical Field

[0001] The utility model relates to the technical field of silicone rubber production equipment, in particular to a cutting device for silicone rubber production. Background Art

[0002] Silicone rubber is a high-performance synthetic material that is widely used in many industries, such as food processing, medical equipment, automotive manufacturing, aerospace, etc., due to its excellent temperature resistance, weather resistance, electrical insulation and biocompatibility. These properties make silicone rubber an ideal choice for manufacturing various components that need to work in harsh environments.

[0003] During the processing of silicone rubber, it is necessary to cut the silicone rubber sheets into silicone rubber sheets of different widths and lengths according to different needs. The structure is such as the Chinese utility model patent "A rubber cutting machine for silicone rubber processing" with announcement number CN221364927U. This patent is equipped with an embedded detachable cutting knife device with a simple structure and convenient operation, which can improve the convenience of disassembling and fixing the cutting knife. It can not only improve the convenience of replacing and maintaining the cutting knife, but also improve the convenience of adjusting the cutting size of the silicone rubber by replacing the cutting knives with different spacings. However, in actual use, there are still certain defects. For example, in the above patent, silicone rubber can only be cut in one direction, that is, multiple sets of cutting knives can be used to cut the entire silicone rubber into several long strips. When the silicone rubber strip needs to be cut into multiple pieces of silicone rubber of a certain length or width due to size requirements, secondary cutting is required, which is time-consuming and labor-intensive, affecting the cutting efficiency of the silicone rubber.

[0029] See also Figure 1-5 A cutting device for silicone rubber production includes a cutting table 1. A first conveying mechanism 2 and a second conveying mechanism 3 are respectively provided on both sides of the upper end of the cutting table 1. The first conveying mechanism 2 includes a first conveying roller 21. First side plates 22 fixed to the cutting table 1 are provided on both sides of the first conveying roller 21. A first motor 23 is mounted on the outside of one of the first side plates 22. The drive shaft of the first motor 23 is connected to the first conveying roller 21. The first conveying roller 21 is rotatably connected to the first side plate 22 on a side away from the first motor 23.

[0030] The second conveying mechanism 3 includes a second conveying roller 31. Second side plates 32 fixedly connected to the cutting table 1 are provided on both sides of the second conveying roller 31. A second motor 33 is mounted on the outside of one of the second side plates 32. The drive shaft of the second motor 33 is connected to the second conveying roller 31. The second conveying roller 31 is rotatably connected to the second side plate 32 on the side away from the second motor 33.

[0031] By starting the first motor 23 and the second motor 33, the first conveyor roller 21 and the second conveyor roller 31 are driven to rotate respectively, and the two first side plates 22 and the two second side plates 32 are used to keep the first conveyor roller 21 and the second conveyor roller 31 stable. Then, the silicone rubber sheet to be cut is put in from one side of the first conveyor roller 21, and the first conveyor roller 21 conveys the silicone rubber sheet toward the second conveyor roller 31. The silicone rubber sheet is then conveyed by the second conveyor roller 31 to the bottom of the transverse cutting blade 51 for cutting.

[0032] Preferably, a supporting frame 4 is provided on the cutting table 1 on the side of the second conveying mechanism 3 away from the first conveying mechanism 2, and a cylinder 41 is installed on both sides of the upper end of the supporting frame 4. A loading plate 5 is provided in the supporting frame 4, and the telescopic column of the cylinder 41 passes through the supporting frame 4 and is fixedly connected to the loading plate 5. A transverse cutting knife 51 is fixedly provided at the lower end of the loading plate 5, and a plurality of U-shaped mounting frames 6 are detachably slidingly provided on the side of the loading plate 5 away from the second conveying mechanism 3. A longitudinal cutting knife 7 is fixedly provided at the lower end of the U-shaped mounting frame 6, and one side of the longitudinal cutting knife 7 is in contact with the transverse cutting knife 51.

[0033] Specifically, when the silicone rubber sheet moves below the transverse cutting knife 51 and the longitudinal cutting knife 7, the two cylinders 41 push the loading plate 5, so that the loading plate 5 can simultaneously push down the transverse cutting knife 51 and the longitudinal cutting knife 7 to cut the silicone rubber sheet, wherein the transverse cutting knife 51 can cut the silicone rubber sheet into long silicone rubber strips, and the longitudinal cutting knife 7 cuts the silicone rubber strips into multiple sections, and the longitudinal cutting knife 7 is connected to the U-shaped mounting frame 6, and the U-shaped mounting frame 6 is detachably slidably set on the loading plate 5, so that the number of longitudinal cutting knives 7 can be increased or decreased according to actual needs, and the distance between each longitudinal cutting knife 7 can be adjusted at the same time to meet the requirements of different lengths of silicone rubber strips, and transverse and longitudinal cutting can be performed simultaneously to improve the silicone rubber cutting efficiency.

[0034] The U-shaped mounting frame 6 includes an upper stop 61, a lower stop 62, and an outer stop 63 between the upper stop 61 and the lower stop 62. A sliding portion 64 is provided on the side opposite to the upper stop 61 and the lower stop 62. Slideways 52 corresponding to the sliding portions 64 are provided on the upper and lower sides of the loading plate 5, so that the U-shaped mounting frame 6 can slide into the slideways 52 through the sliding portions 64 to be slidably arranged on the loading plate 5.

[0035] A first through hole 611 is formed on the upper stopper 61, and a first knob 612 is screwed into the first through hole 611. The lower end of the first knob 612 passes through the first through hole 611 and is connected to a first positioning block 613. A first positioning slot 53 corresponding to the first positioning block 613 is formed on the upper side of the loading plate 5.

[0036] A second through hole 631 is defined on the outer stop 63 , a second knob 632 is screwed into the second through hole 631 , the lower end of the second knob 632 passes through the second through hole 631 and is connected to a second positioning block 633 , and a second positioning long groove 54 corresponding to the second positioning block 633 is defined on the upper side of the loading plate 5 .

[0037] Specifically, when the longitudinal cutting blade 7 is installed on one side of the transverse cutting blade 51 by installing the U-shaped mounting frame 6, the sliding portions 64 of the upper stopper 61 and the lower stopper 62 are slid into the slideways 52 opened above and below the loading plate 5, and then the first knob 612 is screwed to the first through hole 611, thereby pushing the first positioning block 613 downward and applying pressure to the inner wall of the first positioning slot 53, thereby fixing the position of the U-shaped mounting frame 6 and the longitudinal cutting blade 7. Then, the second knob 632 is screwed to the second through hole 631, thereby pushing the second positioning block 633 toward the second positioning slot 54 and applying pressure to the inner wall of the second positioning slot 54, thereby further reinforcing the position of the U-shaped mounting frame 6 and the longitudinal cutting blade 7, and preventing the longitudinal cutting blade 7 from being displaced during the cutting process.

[0038] By means of the above-mentioned assembly method, it is possible to achieve the effect of installing multiple longitudinal cutting knives 7 on the loading plate 5. At the same time, the positions of the longitudinal cutting knives 7 can be fixed after adjusting the spacing between them, thereby achieving the effect of cutting multiple sections of silicone rubber strips at one time, saving time and effort and being highly efficient.

[0039] Furthermore, by loosening the first knob 612 and the second knob 632, the U-shaped mounting frame 6 can be loosened, and then the U-shaped mounting frame 6 can be slid to one side and removed from the loading plate 5, which is convenient for disassembly and assembly, and the number of longitudinal cutting blades 7 can be quickly adjusted.

[0040] Preferably, both the first positioning block 613 and the second positioning block 633 are provided with an anti-slip plate 8 , and the anti-slip plate 8 has an anti-slip concave-convex texture 81 .

[0041] Specifically, the anti-slip plate 8 can be made of anti-slip materials such as rubber and silicone. When the first positioning block 613 and the second positioning block 633 apply pressure to the inner walls of the first positioning long groove 53 and the second positioning long groove 54, the anti-slip plate 8 is squeezed and deformed, and the anti-slip concave-convex texture 81 is used to increase the contact area with the inner walls of the first positioning long groove 53 and the second positioning long groove 54, thereby increasing the firmness of the first positioning block 613 and the second positioning block 633 and the first positioning long groove 53 and the second positioning long groove 54, and avoiding sliding.

[0042] Preferably, the longitudinal cutting knife 7 has a corner portion 71 on the side facing the transverse cutting knife 51, and the angle of the corner portion 71 is the same as the inclination angle of the tip of the transverse cutting knife 51, so that the tip of the longitudinal cutting knife 7 can form a right angle with the tip of the transverse cutting knife 51.

[0043] Specifically, the corner portion 71 is utilized to enable the longitudinal cutting blade 7 to be in close contact with the transverse cutting blade 51 , thereby avoiding a gap at the angle that would cause the longitudinal cutting blade 7 to be unable to cut the silicone rubber strip.

[0044] Preferably, a scale plate 10 is provided on the upper side of the loading plate 5 , and a pointing block 65 corresponding to the scale plate 10 is provided on one side of the upper stop 61 .

[0045] Specifically, the position of the longitudinal cutting knife 7 can be precisely adjusted by utilizing the pointing block 65 and the scale plate 10 additionally provided on the loading plate 5 .

[0046] Preferably, limiting grooves 42 are provided on both sides of the support frame 4 , limiting rods 43 are connected in the limiting grooves 42 , and fixing blocks 55 are provided on both sides of the loading plate 5 , which are slidably sleeved on the limiting rods 43 .

[0047] Specifically, when the cylinder 41 drives the loading plate 5 to move up and down, the fixed blocks 55 on both sides of the loading plate 5 are slidably sleeved on the limit rods 43 set in the limit grooves 42, which can improve the stability, that is, reduce the shaking of the loading plate 5 when being pushed, thereby improving the cutting accuracy and making the cut surface smoother.

[0048] Preferably, two support rods 9 are provided on the cutting table 1 away from the supporting frame 4, and a horizontal plate 91 is connected to the two support rods 9. A plurality of rotating rollers 92 are rotatably provided between the two horizontal plates 91, and a reinforcement rod 93 is provided on the lower end of the horizontal plate 91 away from the support rod 9. The reinforcement rod 93 is fixedly connected to the cutting table 1 to form a triangular support.

[0049] Specifically, a support frame is composed of a support rod 9, a horizontal plate 91 and a reinforcement rod 93. When placing the silicone rubber sheet to be cut, the silicone rubber sheet is placed on the rotating roller 92, and then the silicone rubber sheet is pulled down to pass through the first conveyor roller 21. The position of the first conveyor roller 21 forms an inverse angle with the rotating roller 92 closest to the first conveyor roller 21, so that the first conveyor roller 21 presses the silicone rubber sheet to increase the tension of the silicone rubber sheet, ensuring that the silicone rubber sheet remains flat when passing through the first conveyor roller 21 and moving to the second conveyor roller 31, thereby making cutting smoother and the cutting surface flatter.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
