Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0041] Please refer to Figures 1-12 A cutting device applied to silicone rubber, comprising a base 100, the base 100 is sequentially provided with a feeding assembly 101, a cutting assembly 102 and a strip carrying assembly 103;

[0042] The feeding assembly 101 comprises a feeding support 104 arranged on the base 100, and a conveying belt 105 is arranged on the feeding support 104;

[0043] The cutting assembly 102 comprises a cutting support 106, a cutting bottom plate 107 is fixedly arranged at the upper end of the cutting support 106, a cutting knife mounting plate 108 is fixedly arranged on the cutting bottom plate 107, a plurality of strip mounting grooves 109 are uniformly arranged on the front end of the upper end surface of the cutting knife mounting plate 108 in the longitudinal direction, and a strip cutting knife assembly 110 is arranged in each strip mounting groove 109, and a strip working position 111 is arranged between adjacent strip cutting knife assemblies 110;

[0044] The strip cutting knife assembly 110 comprises a cutting knife adjusting seat 112 fixedly arranged in the strip mounting groove 109 and a cutting knife adjusting part 113 slidingly fitted in the strip mounting groove 109 in the longitudinal direction;

[0045] The cutting knife adjusting part 113 is provided with a threaded adjusting hole 114, the cutting knife adjusting seat 112 is provided with a cutting knife adjusting motor 115, and the working shaft of the cutting knife adjusting motor 115 is provided with a threaded connecting part 116 screwing in the threaded adjusting hole 114;

[0046] The upper ends of the cutting knife adjusting seat 112 and the cutting knife adjusting part 113 are upwardly protruded from the strip mounting groove 109, the first cutting knife 117 and the second cutting knife 118 are fixedly arranged on the side of the upper ends of the cutting knife adjusting seat 112 and the cutting knife adjusting part 113, respectively, which faces the conveying belt 105, and a waste discharging position 119 is arranged between the first cutting knife 117 and the second cutting knife 118;

[0047] The strip carrying assembly 103 comprises a strip carrying plate 120 arranged on the upper end surface of the cutting knife mounting plate 108, the strip carrying plate 120 is provided with a strip containing groove 121 corresponding to the strip working position 111, and the strip carrying plate 120 is provided with a waste containing groove 122 corresponding to the waste discharging position 119;

[0048] The silicone rubber material herein is a flexible solid, and the cutting of the silicone rubber material is, for example, Figure 1 and2 As shown; In the process of using this utility model, the silicone rubber material to be cut is first placed on the conveyor belt 105. The silicone rubber material is fed to the cutting component 102 and the slitting support component 103 via the conveyor belt 105. After passing through the cutter mounting plate 108, the silicone rubber material is slitted and then fed to the slitting support plate 120.

[0049] When the silicone rubber material passes through the cutter mounting plate 108, the silicone rubber material is cut by the slitting cutter assembly 110, and the multi-slitting cutter assembly 110 divides the silicone rubber material into multiple silicone rubber strips.

[0050] Before the slitting cutter assembly 110 cuts the silicone rubber material, the cutter adjustment motor 115 installed in the cutter adjustment seat 112 drives the threaded connector 116 to rotate. The threaded connector 116 rotates in the threaded adjustment hole 114 on the cutter adjustment component 113, thereby driving the cutter adjustment component 113 to slide longitudinally on the cutter mounting plate 108. By rotating the cutter adjustment motor 115 in the forward or reverse direction, the cutter adjustment component 113 can be moved closer to or away from the cutter adjustment seat 112.

[0051] like Figure 11 As shown, when the cutter adjustment component 113 is close to the cutter adjustment seat 112, the relative distance between the first cutter 117 and the second cutter 118 decreases. Conversely, the width of the slitting station 111 between adjacent slitting cutter assemblies 110 increases, thereby increasing the cutting width of the cut silicone rubber strip. The cut silicone rubber strip enters the slitting receiving groove 121 on the slitting support plate 120. At the same time, waste material passes through the space between the first cutter 117 and the second cutter 118 and enters the waste material receiving groove 122 on the slitting support plate 120.

[0052] When the cutting blade adjustment component 113 moves away from the cutting blade adjustment seat 112, the relative distance between the first cutting blade 117 and the second cutting blade 118 increases. Conversely, the width of the slitting station 111 between adjacent slitting cutting blade assemblies 110 decreases, thereby reducing the cutting width of the cut silicone rubber strip. The cut silicone rubber strip enters the slitting receiving groove 121 on the slitting support plate 120. At the same time, waste material passes through the space between the first cutting blade 117 and the second cutting blade 118 and enters the waste material receiving groove 122 on the slitting support plate 120. The waste material is collected in the waste material receiving groove 122, which facilitates subsequent unified grabbing and collection, and then recycling. The recycling rate is high, avoiding the waste of silicone rubber material.

[0053] By setting a plurality of slitting installation grooves 109 on the cutter installation plate 108, and configuring a slitting cutter assembly 110 in each slitting installation groove 109, precise multi-cutting of the silicone rubber material can be achieved, and by adjusting the position of the cutter adjusting part 113 by adjusting the cutter adjusting motor 115, the distance between the first cutter 117 and the second cutter 118 can be finely adjusted to adapt to cutting tasks of different sizes, thereby improving the accuracy and consistency of cutting;

[0054] The conveying belt 105 in the feeding assembly 101 can continuously feed the silicone rubber to be cut to the cutting assembly 102, reducing manual intervention and speeding up the entire cutting process, and the slitting bearing assembly 103 can quickly receive and arrange the cut silicone rubber strips, further improving the overall production efficiency;

[0058] By setting the sealing part 123, the opening of the slitting installation groove 109 is smaller, which avoids interference between the slitting installation groove 109 and the cut silicone rubber strips entering the slitting containing groove 121 and the waste entering the waste containing groove 122 during the process, makes the feeding of the silicone rubber more convenient, and avoids the silicone rubber from entering the slitting installation groove 109 to affect the sliding adjustment of the cutter seat part 126;

[0059] The cutter head part 125 and the cutter seat part 126 are stably connected through the cutter rod part 127, the cutter rod part 127 freely slides in the sealing sliding groove 124, the sliding effect of the cutter adjusting part 113 is more stable, and the position of the cutter is more convenient to adjust;

[0060] The sealing part 123 can effectively prevent external impurities from entering the slitting mounting groove 109, avoiding affecting the normal sliding and operation of the cutting knife, thereby improving the safety and stability of the device. In addition, the design of the threaded adjustment hole 114 extending longitudinally through the knife holder 126 allows the cutting knife adjustment motor 115 to precisely control the movement of the knife holder 126 through the threaded connector 116, further enhancing the stability and reliability of the entire system.

[0061] The presence of the sealing element 123 not only helps protect the internal mechanical parts from contamination, but also facilitates the daily maintenance and cleaning of the equipment. When maintenance or cleaning is required, simply remove the sealing element 123.

[0064] The first cutter 117 and the second cutter 118 are respectively provided with a first inclined surface 128 and a second inclined surface 129 on their opposite sides, which facilitates better collection of waste material into the waste material receiving groove 122. At the same time, the design of the inclined opening facilitates the cutting of silicone rubber material and makes the cutting smoother.

[0067] As shown in Figure 9 , by setting the first lifting column 130 and the second lifting column 131, the elastic abutting plate 139 can be accurately adjusted, the lifting motor 133 drives the lifting adjusting plate 134 to move up and down, so that the cutting knife can be finely adjusted according to different material thicknesses or cutting requirements, thereby ensuring high precision and good adaptability in the cutting process.

[0068] The design of the elastic mounting rod, the spring element 138 and the elastic abutting plate 139 provides additional support and buffering for the cutting operation, which helps to absorb the vibration and impact force generated in the cutting process, reduces the equipment wear and tear, and also ensures the stability of the cutting action, further improves the stability and reliability of the whole system.
