Description

Technical Field

[0001] This utility model relates to the field of blades, specifically a rubber slicer blade that prevents vulcanization adhesion. Background Technology

[0002] Rubber slicing machines are key pieces of equipment in the rubber product processing industry. They are mainly used to cut large blocks of compounded rubber or semi-finished rubber materials into thin slices of precise size and uniform thickness for subsequent vulcanization, molding, and other processes. Their core working component is the high-speed rotating blade, and the cutting performance, durability, and stability of the blade directly affect production efficiency and product quality.

[0003] In existing technologies, during rubber processing, sulfur and other vulcanizing agents are added to the rubber compound to impart specific strength, elasticity, and durability to rubber products. Therefore, the compound itself contains uncrosslinked vulcanized components after mixing. When a blade cuts this type of compound at high speed, the friction generates instantaneous high temperatures, which not only melt the rubber into a viscous flow state but also induces localized vulcanization and crosslinking reactions of the vulcanizing agents on the blade surface.

[0004] However, traditional blades are easily adhered to by sulfides during operation. As the deposits thicken, the sharpness of the blade decreases, resulting in rough slices with uneven thickness and a lower product qualification rate. Therefore, this invention proposes a rubber slicing blade that prevents sulfide adhesion to solve the above problems. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Example 1: Please refer to Figures 1-2 This utility model provides a technical solution: a rubber slicing machine blade for preventing vulcanization adhesion. The blade includes a connecting block 1, with several independent blades 2 fixedly connected to its outer edge. Each blade 2 has several guide grooves 3 on its surface. Each guide groove 3 is elongated and includes an inlet end 4 and an outlet end 5. The inlet end 4 is located at the front end of the blade 2 in the direction of rotation, and the outlet end 5 is located at the rear end of the blade 2 in the direction of rotation. The groove of the inlet end 4 has an arc-shaped profile, and the smooth profile guides the adhering material into the groove. The material enters the guide channel 3 to reduce the initial resistance. The outline of the channel at the outlet end 5 is sharp. The width of the guide channel 3 gradually narrows from the inlet end 4 to the outlet end 5, so that the adhering material is stretched and thinned during high-speed rotation. The blade 2 is located on the surface around the outlet end 5 of the guide channel 3 and has several exhaust holes 6. The exhaust holes 6 are spaced apart to ensure no dead corners and to prevent the formation of new scale areas. The blade 2 has a fan-shaped structure and is made of high-speed steel. The surface of the blade 2 is coated with an anti-stick coating to effectively delay the occurrence of the sulfidation reaction. First, when the blade 2 cuts the rubber, the high-speed rotation generates intense friction and high temperature. Under the high temperature and high pressure cutting environment, the vulcanizing agent on the surface of the rubber material, which is in an unvulcanized or partially vulcanized state, reacts with the metal surface of the blade 2, causing the rubber to adhere to the surface of the blade 2. The adhering material enters the arc-shaped inlet end 4 of the guide groove 3 opened on the surface of the blade 2. The arc-shaped inlet end 4 is designed to guide the adhering material into the guide groove 3, reducing the initial resistance. The entire guide groove 3 is long and narrow, and the width of the groove gradually narrows from the inlet end 4 to the outlet end 5, causing the adhering material to be elongated and thinned during high-speed rotation, damaging its internal structural strength and making it easier to be peeled off by subsequent actions. When it reaches the outlet end 5, the outline of the outlet end 5 is sharp, and the cross-sectional area of ​​the guide groove 3 is reduced to form a low-pressure area, thereby guiding the adhering material out.

[0016] Simultaneously, the high-speed rotating blade 2 cuts the gas. The gas is lightweight and less affected by centrifugal force, but extremely sensitive to pressure differences. The low-pressure zone formed at the outlet end 5 of the guide channel 3, along with several exhaust holes 6 around the outlet end 5, generates a suction force to expel the gas. The gas is discharged through the exhaust holes 6, while adhering debris is flung away from the side guide channel 3. This effectively prevents the blade 2 from forming an air cushion, ensuring smooth cutting and a clean surface. Furthermore, the exhaust holes 6 quickly replenish air during blade retraction, preventing vacuum adhesion from forming on the surface of the blade 2 due to high-speed rotation, further preventing adhesion. Through the synergistic effect of the guide channel 3 and the exhaust holes 6, a dual function of anti-sticking and chip removal is achieved, jointly solving the problems of blade 2 dulling and increased cutting resistance caused by scale buildup, ensuring a clean cut surface and improving product yield.

[0017] The fan-shaped structure of blade 2 effectively reduces resistance during high-speed movement in the air, reduces vibration, and ensures smooth operation of blade 2, thereby providing more stable and precise cutting. The fan-shaped opening structure can more smoothly "throw" the cut rubber sheet and the adhering material peeled off by the guide groove 3 towards the tangential direction when rotating, preventing debris from accumulating around blade 2 and playing an auxiliary role in chip removal. Blade 2 is made of high-speed steel to ensure that the cutting edge 8 can maintain its sharpness for a long time. The anti-stick coating on the surface of blade 2 is a Teflon coating, which makes the surface of blade 2 very smooth and chemically inert, preventing the active components such as vulcanizing agents in rubber from directly contacting blade 2 and effectively delaying the occurrence of vulcanization reaction.

[0018] Example 2: Based on Example 1, please refer to... Figures 3-4 The blade 2 is provided with a front cutting edge 7 connected to the connecting block 1 on the front side, and a cutting edge 8 on the outer edge of the blade 2. A sharp cutting edge 9 is provided at the intersection of the front cutting edge 7 and the cutting edge 8, which can reduce cutting resistance. The blade 2 is provided with a side edge 10 connected to the connecting block 1 on the rear side. A connecting hole 11 is provided on the surface of the connecting block 1, and a positioning groove 12 is provided on the side of the connecting hole 11 to ensure that the entire blade will not slip during the high-speed rotation of the spindle of the rubber slicer. The connecting hole 11 of the blade is connected to the main shaft of the rubber slicer, and the positioning groove 12 is matched with the main shaft to ensure that the entire blade will not slip during high-speed rotation, thus ensuring the accuracy and stability of the transmission. The front edge 7 of the blade 2, which is connected to the connecting block 1, first contacts the rubber and undertakes the main initial cutting and compression. The sharp edge 9, which is set at the intersection of the front edge 7 and the blade 8, serves as an efficient stress concentration point, which can easily cut the surface of the rubber material and significantly reduce the overall cutting resistance. The blade 8 is set on the outer edge of the blade 2 as the main cutting edge to complete the separation and cutting of the rubber material. The side edge 10, which is connected to the connecting block 1, is set on the rear side of the blade 2, ensuring the structural strength and overall rigidity of the connection between the blade 2 and the connecting block 1.
