Description

Technical Field

[0001] The utility model relates to the technical field of cutting, and more specifically, to a silicone rubber heat-conducting cutting device. Background Technique

[0002] Silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and usually two organic groups are connected to the silicon atoms. Ordinary silicone rubber is mainly composed of siloxane chain segments containing methyl and a small amount of vinyl.

[0003] When cutting current silicone rubber into independent block-shaped heat-conducting silicone rubber sheets, the silicone rubber is usually manually arranged at the lower end of the cutting knife, and the cutting knife is driven by a hydraulic cylinder to cut it. After each cutting by the cutting knife, the uncut part of the silicone rubber is manually moved. During the moving process, due to the poor accuracy of manual movement, it is easy to cause deviation in the size between each heat-conducting silicone rubber sheet. In view of this, we propose a silicone rubber heat-conducting cutting device. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a silicone rubber heat-conducting cutting device to solve the technical problem that the size deviation is easy to occur between each heat-conducting silicone rubber sheet when manually moving the uncut part of the silicone rubber.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A silicone rubber heat-conducting cutting device, including a workbench, a conveyor belt is arranged in the workbench, a support frame is fixedly connected to the upper end surface of the conveyor belt, and rotating rollers are movably arranged on both symmetric sides inside the conveyor belt. One of the rotating rollers penetrates through the side wall of the workbench and is provided with an intermittent component.

[0006] The intermittent component includes a gear fixedly arranged at the end of one of the rotating rollers. A half gear is meshed with the surface of the gear. The half gear is fixedly connected with a limiting plate. The limiting plate is symmetrically distributed with the teeth of the half gear. An arc-shaped plate is fixedly arranged on one side of the gear relative to the half gear. The arc-shaped plate is movably connected with the limiting plate, and the side where the arc-shaped plate is connected with the limiting plate is set as an arc surface.

[0007] The utility model can make the surface of the silicone rubber evenly cut into equal lengths of each independent silicone rubber during continuous transmission to the cutting scissors, improving the cutting accuracy of the silicone rubber.

[0008] Preferably, a cutting component is arranged inside the support frame.

[0009] The cutting assembly includes a hydraulic cylinder fixedly connected to the upper end face of the support frame. The telescopic end of the hydraulic cylinder penetrates through the side wall of the support frame and is fixedly connected to a connecting plate. Symmetrically arranged on both sides of the connecting plate are I-shaped frames, and a rotating mechanism is movably arranged within the I-shaped frames.

[0010] Preferably, the rotating mechanism includes rotating plates symmetrically and movably distributed on both sides of the I-shaped frame. A connecting piece is fixedly connected to one side of one of the rotating plates, a limiting groove is formed within the connecting piece, and a limiting block is slidably connected within the limiting groove.

[0011] Preferably, the limiting block is fixedly arranged on the side of the other rotating plate, and a torsion spring is simultaneously clamped within the two rotating plates.

[0012] Preferably, the rotating plate includes a connecting portion and an inclined portion. A cutting cavity is formed between the inclined portions of the two rotating plates. The cutting cavity is arranged in a rectangular shape, and a limiting roller is rotatably connected to the end of the inclined portion.

[0013] Preferably, a cutting knife is fixedly connected to the lower end face of the connecting plate, and the surface of the cutting knife is simultaneously arranged within the cutting cavity.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By providing an intermittent assembly, the present utility model can drive the gear to rotate one full turn when the semi-gear rotates half a turn, and then make the limiting plates fit and connect with each other, so that the gear can be in a suspended state, providing a residence time for the silicone rubber to be arranged directly below the cutting knife. Moreover, using the intermittent effect of equal distance, when the surface of the silicone rubber is continuously transmitted to the cutting knife, the independent cutting lengths of each piece of silicone rubber formed by cutting are equal, improving the cutting accuracy of the silicone rubber.

[0016] 2. The present utility model also provides a cutting assembly and a rotating mechanism. When the cutting knife moves downward to cut the silicone rubber, by using the torque of the torsion spring and the inclined surface of the inclined portion of the rotating plate, the surface of the limiting roller first contacts the surface of the silicone rubber. Subsequently, when the inclined surface of the inclined portion expands, the torsion spring is twisted, and the limiting roller rolls on the surface of the silicone rubber. This can press and smooth the silicone rubber when the cutting knife cuts the silicone rubber, improving the flatness of the cutting edge of the cutting knife and enhancing the cutting efficiency and effect.

[0023] As Figures 1 to 4 shown, a silicone rubber heat-conducting cutting device related to the present utility model includes a workbench 1. A conveyor belt 2 is arranged inside the workbench 1. A support frame 3 is fixedly connected to the upper end surface of the conveyor belt 2. Rotating rollers are movably arranged on both symmetric sides inside the conveyor belt 2. An intermittent component 4 is arranged through the side wall of the workbench 1 on the surface of one of the rotating rollers;

[0024] The intermittent component 4 includes a gear 401 fixedly arranged at the end of one of the rotating rollers. A half gear 402 is meshed and connected to the surface of the gear 401. The half gear 402 drives the gear 401 through a motor. The number of teeth of the half gear 402 is the same as that of the gear 401. A limit plate 403 is fixedly connected to the half gear 402. The limit plate 403 is symmetrically distributed with the teeth of the half gear 402. An arc plate 404 is fixedly arranged on one side of the gear 401 relative to the half gear 402. The arc plate 404 is movably connected to the limit plate 403. The side of the arc plate 404 connected to the limit plate 403 is set as an arc surface. By setting the intermittent component 4, as Figure 1 and Figure 2 shown, by driving the half gear 402 to rotate through a motor, the gear 401 can be driven to rotate one week when the half gear 402 rotates half a week. Subsequently, the limit plate 403 is in fitting connection with the limit plate 403, so that the gear 401 can be in a suspended state, which can provide a residence time for the silicone rubber after it is arranged directly below the cutting scissors 503, and by using the intermittent effect of the same distance, when the surface of the silicone rubber is continuously transported to the cutting scissors 503, the independent silicone rubber cutting lengths formed by each cutting are equal, improving the accuracy of silicone rubber cutting.

[0025] In an embodiment of the present utility model, a cutting component 5 is arranged inside the support frame 3;

[0026] The cutting component 5 includes a hydraulic cylinder fixedly connected to the upper end face of the support frame 3. The telescopic end of the hydraulic cylinder penetrates through the side wall of the support frame 3 and is fixedly connected with a connecting plate 502. A cutting knife 503 is fixedly connected to the lower end face of the connecting plate 502. I-shaped frames 501 are fixedly connected to the symmetric two sides of the connecting plate 502. A rotating mechanism 6 is movably arranged in the I-shaped frames 501. The rotating mechanism 6 includes rotating plates 601 symmetrically and movably distributed on the two sides of the I-shaped frames 501. A connecting piece 602 is fixedly connected to one side of one of the rotating plates 601. A limiting groove is formed in the connecting piece 602. A limiting block 603 is slidably connected in the limiting groove. The limiting block 603 is fixedly arranged on the side of the other rotating plate 601. A torsion spring 604 is clamped in the two rotating plates 601 at the same time. The rotating plate 601 includes a connecting portion 6011 and an inclined portion 6012. A cutting cavity is formed between the inclined portions 6012 of the two rotating plates 601. The cutting cavity is arranged in a rectangular shape. The surface of the cutting knife 503 is arranged in the cutting cavity at the same time. A limiting roller 605 is rotatably connected to the end of the inclined portion 6012. By arranging the cutting component 5 and the rotating mechanism 6, when the cutting knife 503 moves downward to cut the silicone rubber, the torque of the torsion spring 604 and the inclined surface of the inclined portion 6012 of the rotating plate 601 can be utilized, so that the surface of the limiting roller 605 first contacts the surface of the silicone rubber. Subsequently, when the inclined surface of the inclined portion 6012 expands, the torsion spring 604 is distorted, and the limiting roller 605 rolls on the surface of the silicone rubber. When the cutting knife 503 cuts the silicone rubber, the silicone rubber can be pressed and smoothed, the flatness of the cut of the cutting knife 503 can be improved, and the cutting efficiency and effect can be improved.

[0027] Working principle: This embodiment provides a silicone rubber heat-conducting cutting device. When in use, first place the silicone rubber on the surface of the conveyor belt 2, start the motor, which drives the half gear 402 and the limit plate 403 to rotate simultaneously. During the rotation, the half gear 402 first contacts the gear 401, driving the gear 401 and the conveyor belt 2 to operate, and conveying the silicone rubber to directly below the cutting knife 503. At this time, the gear 401 completes one full rotation, and the half gear 402 rotates half a turn. Subsequently, the surface of the limit plate 403 contacts the arc surface of the arc plate 404. At this time, the gear 401 disengages from the half gear 402 and is in a suspended state. At this time, through the stretching movement of the hydraulic cylinder, the connecting plate 502 is driven to move downward. During the downward movement, the surface of the limit roller 605 first contacts both sides of the surface of the silicone rubber, and under the continuous movement of the connecting plate 502, an extrusion force is generated on the limit roller 605, thereby generating a torque on the torsion spring 604, causing the inclined portion 6012 to expand the cutting cavity according to its inclination, so that the two limit rollers 605 move away from each other. While expanding, the entire rotating mechanism 6 sinks within the I-shaped frame 501. Subsequently, the tip of the cutting knife 503 contacts the surface of the silicone rubber and cuts it. At the same time as the cutting is completed, the half gear 402 completes one full rotation. At this moment, the surface of the limit plate 403 disengages from the arc surface of the arc plate 404, and the teeth of the half gear 402 mesh with the surface of the gear 401, driving the conveyor belt 2 to perform the next round of operation, driving the silicone rubber to be conveyed directly below the cutting knife 503 again.
