Description

[0001] The present invention relates to the technical field of rubber V - belt processing, and specifically to a device and method for preparing a fiber - reinforced rubber V - belt. Background Art

[0002] In the field of rubber V - belt preparation, fiber - reinforcement technology can significantly improve the tensile strength, fatigue resistance, and durability of products by introducing high - strength fibers (such as aramid and glass fiber); however, the problem of uneven mixing of fibers and the rubber matrix in the current process significantly restricts the improvement of product performance.

[0003] The patent application with the application number CN201621034009.5 discloses an efficient rubber V - belt processing system, including a rubber layer preparation device, a continuous coating device, a multi - functional forming and integrated cutting device, a V - belt core chamfering device, and a vulcanization die - pressing device. The rubber layer preparation device is used to mix raw materials to form a rubber layer. The continuous coating device includes a coating base and a continuous coating unit, and the continuous coating unit coats the inner lining on the rubber layer to form a tape. The multi - functional forming and integrated cutting device is used to press - form the tape and cut it into a blank tape. The V - belt core chamfering device chamfers and cuts the core to form a V - belt, and the vulcanization die - pressing device applies pressure to the die during vulcanization.

In the production of fiber - reinforced rubber V - belts, uneven dispersion of fibers and rubber during mixing is likely to occur, with fibers agglomerating or locally enriching in the rubber matrix.

[0013] A method for preparing a fiber-reinforced rubber V-belt preparation device comprises the following steps: S1.

If they exist, start the hydraulic pump to adjust the spacing of the rotating rods, and synchronously drive the semicircular barrel to move to keep the gap stable; S3, re-adding the raw materials still containing agglomerates, using the blades with reduced spacing to enhance the shear force, mixing again and testing until the agglomerates are eliminated; S4. During the mixing process, constant temperature water flows into the circulation chamber of the rotating rod through the water inlet pipe, circulates through the guide frame, and balances the temperature in the mixing box; S5.

The ultrasonic transducer applies high-frequency vibration to the mixed raw materials, and uses cavitation to break up the bubbles, thereby completing the preparation of the fiber-reinforced rubber V-belt raw materials.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The fiber-reinforced rubber V-belt preparation device is provided with an adjustment mechanism 1, and uses a double rotating rod and a paddle to perform mixing and extrusion. When the double rotating rod rotates, the paddle forms a plurality of sealed chambers, and the rubber and the fiber are subjected to strong shearing, extrusion and stretching in the chamber, which can break the fiber agglomerates and make them evenly dispersed in the rubber matrix. At the same time, the adjustment mechanism 1 can adjust the spacing between the double rotating rod and the paddle, thereby realizing precise control of the dispersion degree of the fiber in the rubber matrix and improving the uniformity and performance of the composite material.

[0015] 2. The fiber-reinforced rubber V-belt preparation device is provided with an adjustment mechanism 2. When the spacing between the double rotating rods and the paddles is adjusted, the barrel can synchronously follow the spacing to move its position, thereby ensuring that the gap between the double rotating rods, the paddles and the inner wall of the barrel always remains stable, effectively avoiding the "leakage" phenomenon of materials during transportation due to changes in the spacing, preventing the problem of insufficient dispersion of fibers due to reduced shearing effect, and creating a stable shearing environment by adjusting the relative position of the rotating parts and the barrel in a linked manner, ensuring that the fibers are evenly dispersed in the rubber matrix, and improving the stability of the mixing process and the quality of the composite material.

[0016] 3. This fiber-reinforced rubber V-belt manufacturing device, through the coordinated cooperation of adjustment mechanism 1 and adjustment mechanism 2, when adjusting the distance between the double rotating rods and the blades, the barrel can automatically move along with them without the need for additional external force drive, ensuring that the gaps between the double rotating rods, the blades and the inner wall of the barrel are always constant, avoiding local accumulation of raw materials caused by gap changes. At the same time, the stable gap design can balance the internal shear force and heat conduction, preventing the decrease in fiber dispersion effect caused by material retention or uneven temperature. The two mechanisms achieve dynamic gap compensation through mechanical linkage, creating a uniform mixing environment and effectively improving the dispersion uniformity and mixing efficiency of fibers in the rubber matrix.

[0017] 4. This fiber-reinforced rubber V-belt manufacturing device, through the setting of a stabilization mechanism, uses the water circulation system inside the rotating rod to accurately control the temperature stability during raw material mixing, effectively avoiding the problem of gas expansion caused by local overheating. At the same time, the ultrasonic transducer can generate high-frequency vibrations, causing the bubbles in the composite material to break and discharge under the cavitation effect, reducing the interference of bubbles on the mixing process of raw materials and fibers. This mechanism, through the coordinated action of thermal control and ultrasound, balances the mixing temperature field, inhibits the generation and aggregation of bubbles, creates a stable environment for the uniform dispersion of fibers in the rubber matrix, and improves the mixing quality and performance uniformity of the composite material.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0022] In the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Example 1: Refer to Figures 1 - 6 , the present invention provides a technical solution: A rubber V-belt preparation device containing fiber reinforcement, including a base 1, and an adjusting mechanism 3 is fixedly connected to the upper surface of the base 1. The adjusting mechanism 3 includes: A rotating rod 304, with blades 305 fixedly connected to the outer surface of the rotating rod 304. There are two groups of the rotating rod 304 and the blades 305 arranged symmetrically. The rotating rod 304 and the blades 305 are used for kneading raw materials; Mixing box 301, inside which there is a fixedly connected rotating collar 302, on the outer surface of the rotating collar 302 there is a fixedly connected telescopic baffle 303, and the telescopic baffle 303 is used to block the mixing box 301; Rotating ring 307, on the outer surface of the rotating ring 307 there is a snap-connected limit frame 308, and on the outer surface of the limit frame 308 there is a fixedly connected hydraulic pump 309, and the hydraulic pump 309 is used to push the rotating rod 304.

[0024] On the upper surface of the mixing box 301 there is a fixedly connected feeding port 2, inside the mixing box 301 there is a discharge port 4 opened, on the outer surface of the mixing box 301 there is a fixedly connected adjusting mechanism two 5, inside the rotating rod 304 there is a fixedly connected stabilizing mechanism 6, and the adjusting mechanism one 3 further includes a rotating box 306, the rotating box 306 is fixedly connected with the mixing box 301, inside the rotating box 306 there is a fixedly connected motor 310, inside the rotating box 306 there is a screw-connected tensioning device 311, and inside the rotating box 306 there is a clamped arc-shaped hole one 312, and the arc-shaped hole one 312 is used to adapt to the movement of the rotating rod 304.

[0025] The rotating collar 302 is rotatably connected with the rotating rod 304, the outer surface of the telescopic baffle 303 is flush with the inner wall of the mixing box 301, the rotating ring 307 is fixedly connected with the rotating rod 304, the output end of the motor 310 is connected with the rotating rod 304 through a synchronous belt drive structure, the arc-shaped hole one 312 is slidably connected with the rotating rod 304, the rotating box 306 is used to protect the hydraulic pump 309, after the distance between the rotating rods 304 is adjusted, the tensioning device 311 is used to pull the synchronous belt of the synchronous belt drive structure outwards, so that when the motor 310 rotates the rotating rod 304, it can still be accurately driven. When the distance between the rotating rods 304 is adjusted, the rotating rod 304 slides inside the arc-shaped hole one 312, and at the same time the telescopic baffle 303 is compressed, and through the compression of the telescopic baffle 303 and the rotation of the rotating rod 304 inside the rotating collar 302, it is ensured that the inner wall of the mixing box 301 is smooth and material jamming is avoided.

[0026] During the process of mixing the raw materials of the fiber-reinforced rubber V-belt, due to the addition of extra fiber materials, the phenomenon of fiber agglomeration or local enrichment in the rubber matrix may occur. Therefore, the adjusting mechanism one 3 is needed to assist in mixing the rubber and fibers, disperse the fiber agglomerates, make them evenly disperse in the rubber matrix, and improve the uniformity of the composite material.

[0027] The second adjusting mechanism 5 includes an arc-shaped plate 501. The arc-shaped plate 501 is fixedly connected to the mixing box 301. A rectangular hole 502 is provided inside the arc-shaped plate 501. A clamping plate 503 is clamped inside the rectangular hole 502. A semi-cylindrical barrel 504 and a connecting plate 505 are fixedly connected to the outer surface of the clamping plate 503. A limiting plate 506 is fixedly connected to the outer surface of the connecting plate 505. A telescopic rubber sleeve 507 and a rubber band 508 are fixedly connected to the outer surface of the connecting plate 505. The telescopic rubber sleeve 507 is used to protect the clamping plate 503.

[0028] The semi-cylindrical barrel 504 is clamped with the mixing box 301. The limiting plate 506 is rotatably connected to the rotating rod 304. The outer surface of the telescopic rubber sleeve 507 is fixedly connected to the outer surface of the arc-shaped plate 501. The outer surface of the rubber band 508 is fixedly connected to the outer surface of the mixing box 301. The rubber band 508 is used to tension the connecting plate 505. When the clamping plate 503 moves inside the rectangular hole 502, the telescopic rubber sleeve 507 protects the clamping plate 503, preventing external contamination from entering the inside of the mixing box 301 through the telescopic rubber sleeve 507. And through the setting of the arc-shaped plate 501, the telescopic rubber sleeve 507 can horizontally expand and contract to ensure the protection effect. And through the continuous pulling of the rubber band 508 on the connecting plate 505, the connecting plate 505 is prevented from being bent due to continuous stress.

[0029] When adjusting the distance between the rotating rods 304, the gap between the paddle blades 305 and the mixing box 301 increases, resulting in a "leakage flow" phenomenon during the material transportation process, and causing local accumulation of the rubber raw material inside the mixing box 301, affecting the mixing quality and efficiency. Therefore, a stabilizing mechanism 6 is needed to adjust the gap between the inner wall of the mixing box 301 and the paddle blades 305, improving the stability of the mixing process and the quality of the composite material.

[0030] The working principle of this embodiment is as follows: When using this rubber V-belt preparation device with fiber reinforcement, the motor 310 starts, drives the rotating rod 304 to rotate through the synchronous belt drive structure, the rotating rod 304 drives the paddle 305 to rotate, and the two symmetrically arranged rotating rods 304 rotate in opposite directions. At this time, rubber raw materials and fibers are successively added through the feeding port 2, and the paddle 305 kneads the rubber raw materials and fibers. During the rotation of the rubber raw materials, the paddle 305 forms multiple sealed chambers, and the rubber and fibers are subjected to strong shearing, extrusion, and stretching effects in these chambers, which helps to break the fiber agglomerates and make them evenly dispersed in the rubber matrix. The kneaded raw materials for conveying are discharged through the discharge port 4, and the fiber agglomerates in the discharged kneaded raw materials are detected. If there are still fiber agglomerates, at this time, the hydraulic pump 309 contracts, and through the four groups of hydraulic pumps 309 symmetrically arranged at both ends of the rotating rod 304, the limiting frame 308 is evenly driven to move inward, and the rotating rod 304 is driven to move inward through the rotating ring 307, so as to adjust the distance between the symmetrically arranged paddles 305. At this time, the rotating rod 304 drives the connecting plate 505 to move inward through the limiting plate 506, the connecting plate 505 pushes the semi-circular cylinder 504 to move inward through the clamping plate 503, and the distance between the semi-circular cylinder 504 and the rotating rod 304 is fixed through the limiting plate 506, so that the distance between the inner wall of the kneading box 301 and the paddle 305 is always kept unchanged. At this time, the kneaded raw materials still with fiber agglomerates are re-input and kneaded again through the paddle 305. At this time, the distance between the paddles 305 is reduced, and the strong shearing, extrusion, and stretching effects on the rubber and fibers in these chambers are increased. At this time, the fiber agglomerates in the kneaded raw materials are taken out through the discharge port 4 for re-detection. If there are no fiber agglomerates, continuous raw material kneading is carried out. If there are still fiber agglomerates, the distance is continuously adjusted through the above process, and raw material kneading and detection are carried out until there are no fiber agglomerates, and then continuous raw material kneading is carried out.

[0031] Embodiment 2: Please refer to Figures 7 - 9 , on the basis of Embodiment 1, the present invention provides a technical solution: The stabilizing mechanism 6 includes a diversion frame 602. A circulation cavity 601 is provided inside the rotating rod 304, and the diversion frame 602 is fixedly connected to the circulation cavity 601. A through-hole circular plate 603 is fixedly connected to the outer surface of the diversion frame 602, a water inlet pipe 604 is fixedly connected to the outer surface of the through-hole circular plate 603, a rotating head 605 is fixedly connected to the outer surface of the rotating rod 304, a drainage box 606 is rotatably connected to the outer surface of the rotating head 605, a drainage pipe 607 is fixedly connected to the outer surface of the drainage box 606, an arc-shaped hole two 608 is provided inside the diversion frame 602, a sleeve one 609 is fixedly connected inside the diversion frame 602, an ultrasonic transducer 610 is clamped inside the sleeve one 609, an arc-shaped hole three 611 is provided inside the rotating box 306, and the diversion frame 602 is used to support the circulation cavity 601.

[0032] The rotating head 605 is connected to the output end of the motor 310 through a synchronous belt drive structure. The outer surface of the drainage box 606 is rotatably connected to the outer surface of the rotating rod 304. The drain pipe 607 is fixedly connected to the rotating box 306. The arc-shaped hole three 611 is used to adapt to the movement of the water inlet pipe 604. The top of the sleeve one 609 is sealed with a threaded cover to provide water isolation protection for the internal ultrasonic transducer 610. The temperature of the sleeve one 609 is ensured to be stable through the water circulation outside the sleeve one 609. At the same time, when the constant temperature water is discharged, it will move out through the joint of the rotating head 605 and the rotating rod 304. The inside of the drainage box 606 mainly guides it and discharges it through the drain pipe 607 to avoid accumulation inside the rotating box 306.

[0033] During the mixing process, uneven internal temperature may cause bubbles to form, and gases may be mixed during mixing, resulting in bubbles inside the rubber matrix. These bubbles promote fiber agglomeration, and the agglomeration in turn exacerbates bubble retention, ultimately leading to deterioration of material properties, reduction of processing efficiency, and increase of application risks. Therefore, a stabilizing mechanism 6 is needed to balance the temperature inside the mixing box 301, make the temperature stable, and treat the internal bubbles through cavitation.

[0034] The working principle of this embodiment is as follows: When using this fiber-reinforced rubber V-belt preparation device, during the mixing of rubber raw materials, the diversion frame 602 divides the inside of the circulation cavity 601 into two sides. At this time, constant temperature water enters through the water inlet pipe 604 and flows into the side connected to the water inlet pipe 604, stabilizing the temperature of the rotating rod 304 and the paddle 305 on this side. Then it flows through the arc-shaped hole two 608 to the bottom of the circulation cavity 601, and then flows into the space on the other side through the arc-shaped hole two 608 and flows out through the through hole of the diversion frame 602. It can flow into the inside of the drainage box 606 through the gap and hole between the rotating head 605 and the rotating rod 304 and is discharged through the drain pipe 607. At this time, through the circulation of the constant temperature water inside the circulation cavity 601, the high temperature of the rotating rod 304 and the paddle 305 is cooled, and the low temperature part is heated through the circulation of the constant temperature water, so that the telescopic baffle 303, the paddle 305 and the inside of the mixing box 301 are stably matched, thereby ensuring the internal temperature balance, reducing internal bubbles. At the same time, the ultrasonic transducer 610 performs cavitation on the mixed raw materials on the outer surface of the paddle 305 through the sleeve one 609 and the diversion frame 602, so that the formed micro-bubbles experience generation, growth, and collapse, thus avoiding the influence of bubbles on the mixing of rubber raw materials.

[0035] A preparation method of a fiber-reinforced rubber V-belt preparation device includes the following steps: S1. Start the motor 310, drive the double rotating rods 304 and the blades 305 to rotate in opposite directions through the synchronous belt, and add the rubber raw material and the fiber into the mixing tank 301 from the feeding port 2 for preliminary mixing; S2. Detect the fiber aggregates in the discharged mixed raw material. If any exist, start the hydraulic pump 309 to adjust the distance between the rotating rods 304, and simultaneously drive the semi-cylindrical barrel 504 to move to keep the gap stable; S3. Re-input the raw material still containing aggregates, use the blades 305 with reduced distance to enhance the shear force, mix again and detect until the aggregates are eliminated; S4. During the mixing process, the constant temperature water flows into the circulation cavity 601 of the rotating rod 304 through the water inlet pipe 604, and circulates through the flow guiding frame 602 to balance the temperature in the mixing tank 301; S5. The circulating water flows into the drainage tank 606 through the rotating head 605 and is discharged through the drainage pipe 607 to avoid water accumulation and ensure the continuous and stable operation of the temperature control system; S6. The ultrasonic transducer 610 applies high-frequency vibration to the mixed raw material, and uses the cavitation effect to break the bubbles to complete the preparation of the fiber-reinforced rubber V-belt raw material.
