Technical Field
[0001] This invention relates to the field of rubber adhesive technology, specifically to an apparatus and method for preparing adjustable particle size masterbatch for rubber adhesive production. Background Technology
[0002] Rubber adhesives are adhesives formulated primarily from synthetic rubbers such as chloroprene, nitrile, butyl silicone rubber, and polysulfide, or natural rubber. They possess excellent elasticity and are suitable for bonding soft materials or materials with significantly different coefficients of thermal expansion, such as rubber to rubber, rubber to metal, plastic, leather, and wood. They have wide applications in aircraft manufacturing, automobile manufacturing, construction, light industry, and rubber product processing. The production of rubber adhesives requires the production of granules. To facilitate the production of rubber adhesive masterbatches, a particle size-adjustable masterbatch preparation device and method for rubber adhesive production has been developed.
[0003] In existing masterbatch preparation equipment for rubber adhesive production, during masterbatch production, a round hole is often opened at the end of the discharge device of the production equipment, and the extrusion device is driven to extrude the rubber into the round hole. However, the round hole on the production equipment is made of iron, which means that the round hole of the discharge device cannot be changed when producing different types of granules, and the discharge device needs to be replaced, thus affecting the processing speed. Rubber granules need to be heated during molding. After the heated granules are cut and shaped, they will pile up together, which will cause adhesion between the granules, affecting the shape and quality of the shaped granules. Summary of the Invention
[0004] To address the shortcomings of existing adjustable-size masterbatch preparation devices and methods for rubber adhesive production, this invention provides an adjustable-size masterbatch preparation device and method for rubber adhesive production. This device and method features the ability to align three circular holes inside the initial forming plate with three circular holes outside the auxiliary forming plate by installing or removing an auxiliary forming plate at the lower part of the initial forming plate. This allows for the formation of six different types of circular particles. Furthermore, the position of the telescopic column within the adjusting hole of the forming plate facilitates alignment between the initial forming plate and the discharge base. Simultaneously, as particles fall onto the upper part of the slide plate, liquid is transported through a cooling liquid flow limiting plate, ensuring contact between the liquid and particles for efficient cooling and forming. This avoids adhesion between particles that have not yet solidified, thus solving the problems mentioned in the background art.
[0005] This invention provides the following technical solution: a particle size adjustable masterbatch preparation device for rubber adhesive production, comprising a forming tank and a forming funnel. A sliding plate is fixedly connected inside the forming tank. A cooling liquid flow limiting plate is fixedly connected to one side of the upper part of the forming tank. A cooling liquid discharge hole is opened inside the other side of the sliding plate. A forming particle output tank is opened inside the other side of the sliding plate. A discharge base is fixedly connected inside the lower part of the forming funnel. A preliminary forming plate is movably sleeved inside the lower part of the forming funnel. An adjusting hole for the forming plate is opened inside the lower part of the forming funnel. A top cover is movably sleeved on the upper part of the forming funnel. A rotating column is installed inside the top cover. A first gear is fixedly connected to the outside of the middle part of the rotating column. A first reduction gear is meshed with the outside of the first gear. A second reduction gear is fixedly connected to the lower part of the first reduction gear. A stirring scraper is meshed with the outside of the second reduction gear.
[0006] Preferably, the other side of the slide plate is inclined at a 15-degree angle, and water inlet pipes are connected to the inside of both sides of the cooling liquid flow limiting plate. A baffle is installed on the upper part of the other side of the slide plate to facilitate cooling and forming when the forming particles fall, and at the same time to prevent the particles from adhering to the cooling liquid.
[0007] Preferably, a first support plate is fixedly connected to one side of the upper part of the forming groove, a forming funnel is fixedly connected to the upper part of the first support plate, an observation door is installed on the outer side of the first support plate, and a hinge is installed between the observation door and the first support plate. By installing the observation door on the outside of the first support plate, the inner side of the first support plate can be sealed and limited, and at the same time, opening the observation door facilitates the adjustment of the lower part of the forming funnel.
[0008] Preferably, a telescopic column is movably sleeved inside the adjusting hole of the forming plate, and a spring is installed on the lower part of the telescopic column. An auxiliary forming plate is movably sleeved on the lower part of the preliminary forming plate, and the outer side of the auxiliary forming plate is movably sleeved inside the preliminary forming plate. The three sets of grooves on the outer side of the auxiliary forming plate are aligned with the grooves on the lower part of the preliminary forming plate. The grooves on the outer side of the auxiliary forming plate are one millimeter smaller than the grooves on the inner side of the preliminary forming plate, which facilitates the alignment and installation between the preliminary forming plate and the auxiliary forming plate. When the forming funnel discharges material, six different types of round particles are formed.
[0009] Preferably, the interior of the preliminary forming plate has three sets of circular grooves, the distance between the three sets of circular grooves is 15 degrees, and the diameter difference between the three sets of circular grooves is 2 millimeters. The lower part of the forming funnel has four sets of forming plate adjustment holes, and three grooves are formed on the outer side of the forming plate adjustment holes, the distance between the three grooves is 15 degrees. The spring is installed between the lower part of the telescopic column and the auxiliary forming plate. Adjusting the position of the telescopic column inside the forming plate adjustment hole facilitates the adjustment of the position of the preliminary forming plate at the lower part of the forming funnel, which can drive the grooves between the discharge base and the preliminary forming plate to be aligned and installed.
[0010] Preferably, a cutter is fixedly connected to the lower part of the rotating column. The inner side of the cutter can contact the lower parts of the preliminary forming plate and the auxiliary forming plate. The rotating column drives the cutter to rotate, and the cutter cuts off the particles squeezed from the lower part of the auxiliary forming plate.
[0011] Preferably, a second support plate is installed inside the lower part of the stirring scraper, and a positioning plate is installed in the middle of the first reduction gear and the second reduction gear. The inner side of the positioning plate is in close contact with the inner wall of the lower part of the forming funnel. The upper part of the second support plate is circular, and the outer side of the first reduction gear is in close contact with the inner wall of the upper part of the forming funnel. By using the first reduction gear and the second reduction gear, the first gear is driven to rotate, thereby reducing the rotation speed of the stirring scraper and preventing the stirring scraper from rotating too fast and touching and damaging the inner wall of the forming funnel.
[0012] Preferably, a spiral tube is fixedly connected to the lower part of the rotating column, the lower part of the rotating column is movably sleeved inside the discharge base, and the spiral tube is tightly attached to the inner wall of the lower part of the forming funnel. The spiral tube rotates, driving the material inside the forming funnel to be conveyed downward and driving the rubber to be squeezed downward.
[0013] A method for preparing a particle size adjustable masterbatch preparation device for rubber adhesive production includes the following steps:
[0014] S1: The liquid rubber adhesive is filled into the inside of the molding funnel. At the same time, the liquid rubber adhesive is mixed and stirred inside the upper part of the molding funnel and then transported to the lower part of the molding funnel. Simultaneously, the rotating column is started to drive the spiral tube to rotate. The spiral tube drives the rubber adhesive to be squeezed downward and transported downward through the observation door.
[0015] S2: Depending on the required particle diameter, an auxiliary forming plate is installed or removed from the lower part of the preliminary forming plate, and the telescopic column is rotated to align the corresponding circular discharge hole on the outside of the preliminary forming plate with the groove opened inside the discharge base.
[0016] S3: After the discharge diameter is adjusted, when the rotating column rotates, it drives the cutter to stick to the lower part of the auxiliary forming plate or the preliminary forming plate. When the rotating column rotates, it drives the rubber adhesive to be conveyed to the lower part through the groove. The rotating column drives the cutter to rotate, which can drive the rubber adhesive squeezed at the lower part of the preliminary forming plate or the auxiliary forming plate to be cut, thus forming granules.
[0017] S4: When the rotating column rotates, it drives the first gear and the first reduction gear to mesh. At the same time, the first reduction gear drives the second reduction gear to rotate synchronously. When the second reduction gear meshes with the stirring scraper, it can reduce the rotation speed of the stirring scraper and clean the rubber adhesive on the inner wall of the molding funnel. This prevents the rubber adhesive from clogging the inside of the molding funnel and avoids the problem of the stirring scraper rotating too fast and affecting the stirring effect.
[0018] S5: Granular rubber adhesive slides down through the molding funnel into the interior of the upper part of the slide plate, and is connected to a pipe inside the cooling liquid flow restriction plate, which drives the cooling liquid to flow down through the slide plate. The liquid drives the rubber adhesive to cool and form, and the rubber adhesive particles slide out through the molded particle output groove. The coolant is discharged through the cooling liquid discharge hole at the front end of the molded particle output groove, which facilitates the separation between the cooling liquid and the rubber adhesive particles.
[0019] Compared with existing apparatuses and methods for preparing adjustable masterbatch for rubber adhesive production, the present invention has the following advantages:
[0020] 1. The adjustable particle size masterbatch preparation device and method for rubber adhesive production involves the following steps: after the particles are formed, they pass through a cooling liquid flow restriction plate connected to a water pipe, which brings the cooling liquid into contact with the particles and cools and shapes them. At the same time, the particles slide to the other side of the slide plate due to the inclination angle inside the slide plate. The liquid is discharged through the cooling liquid discharge hole, and the formed particles are discharged downward through the formed particle output groove. This facilitates the cooling and shaping of the particles and also separates the particles from the cooling liquid.
[0021] 2. The adjustable particle size masterbatch preparation device and method for rubber adhesive production, by adjusting the position of the telescopic column inside the adjustment hole of the molding plate by installing or removing the auxiliary molding plate at the lower part of the preliminary molding plate according to the particle size, and adjusting the position of the telescopic column inside the adjustment hole of the molding plate. The outer side of the adjustment hole of the molding plate has three grooves, which can drive the telescopic column to engage in the corresponding grooves. This leads to the alignment and installation of the grooves inside the preliminary molding plate and the auxiliary molding plate with the groove inside the discharge base, which facilitates the control and adjustment of the discharge hole size.
[0022] 3. The adjustable particle size masterbatch preparation device and method for rubber adhesive production, by starting the rotating column, drives the first gear to rotate, which in turn drives the first reduction gear to rotate. The first reduction gear drives the second reduction gear to rotate. The diameters of the first and second reduction gears are different, which allows the rotation speed between the second reduction gear and the inner side of the stirring scraper to be adjusted. Thus, when the rotating column rotates, it can reduce the rotation speed of the stirring scraper. When the stirring scraper rotates, it drives the stirring scraper to stick to the inner wall of the forming funnel, which can scrape off the rubber material on the inner wall of the forming funnel and avoid the problem of rubber material clogging the inner wall of the forming funnel. At the same time, a support plate is installed at the lower part of the stirring scraper and the support plate is pressed against the inside of the forming funnel, which can improve the stability of the stirring scraper during rotation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A rubber adhesive production apparatus with adjustable particle size masterbatch preparation includes a molding tank 1 and a molding funnel 7. A sliding plate 2 is fixedly connected inside the molding tank 1, providing space for conveying and molding rubber particles. A cooling liquid flow limiting plate 3 is fixedly connected to one side of the upper part of the molding tank 1, filled with liquid to facilitate cooling and molding of the rubber material. A cooling liquid discharge hole 4 is opened inside the other side of the sliding plate 2, allowing for liquid flow and filtration. A molded particle output channel 5 is opened inside the other side of the sliding plate 2, providing space for discharging rubber particles. A discharge base 9 is fixedly connected inside the lower part of the molding funnel 7, initially compressing the particles into a round shape. A preliminary molding plate 10 is movably sleeved inside the lower part of the molding funnel 7, forming the rubber material into a small diameter. The molded funnel 7 has an internal adjustment hole 11 for the molding plate. The adjustment hole 11 limits the movement space of the telescopic column 12. The upper part of the molding funnel 7 is movably fitted with a top cover 16, which seals and protects the upper part of the molding groove 1. A rotating column 17 is installed inside the top cover 16. The rotating column 17 drives the spiral tube 23 to rotate, which provides power for the stirring device inside the molding funnel 7. A first gear 18 is fixedly connected to the outside of the middle part of the rotating column 17. A first reduction gear 19 is meshed with the outside of the first gear 18. A second reduction gear 20 is fixedly connected to the lower part of the first reduction gear 19. A stirring scraper 21 is meshed with the outside of the second reduction gear 20. By using the first gear 18 and the first reduction gear 19 to drive the rotating column 17 to rotate, the rotation speed of the stirring scraper 21 can be reduced, thus avoiding the problem of the stirring scraper 21 scratching the inner wall of the molding funnel 7.
[0032] refer to Figure 1 and Figure 2 The other side of the slide plate 2 is tilted at a 15-degree angle. Water inlet pipes are connected to the inside of both sides of the cooling liquid flow limiting plate 3. A baffle is installed on the upper part of the other side of the slide plate 2. When the particles are formed, they are connected to the water pipes through the cooling liquid flow limiting plate 3, which drives the cooling liquid to come into contact with the particles and drives the particles to cool and form. At the same time, the tilt angle inside the slide plate 2 drives the particles to slide to the other side of the slide plate 2. The liquid is discharged through the cooling liquid discharge hole 4, and the formed particles are discharged downward through the formed particle output groove 5. This can facilitate the cooling and forming of the particles and also promote the separation between the particles and the cooling liquid.
[0033] refer to Figure 1A first support plate 6 is fixedly connected to one side of the upper part of the forming tank 1. A forming funnel 7 is fixedly connected to the upper part of the first support plate 6. An observation door 8 is installed on the outer side of the first support plate 6. A hinge is installed between the observation door 8 and the first support plate 6. The first support plate 6 is installed between the forming tank 1 and the forming funnel 7 by a driving device, and the position of the forming funnel 7 is supported. At the same time, the observation door 8 is opened to facilitate the installation and adjustment of the position of the auxiliary forming plate 14 and the preliminary forming plate 10. After the observation door 8 is closed, the problem of particles falling during forming can be avoided.
[0034] refer to Figure 4 and Figure 5 A telescopic column 12 is movably sleeved inside the adjusting movable hole 11 of the forming plate. A spring 13 is installed on the outside of the lower part of the telescopic column 12. An auxiliary forming plate 14 is movably sleeved on the lower part of the preliminary forming plate 10. The outer side of the auxiliary forming plate 14 is movably sleeved inside the preliminary forming plate 10. The three sets of grooves on the outside of the auxiliary forming plate 14 are aligned with the grooves on the lower part of the preliminary forming plate 10. The grooves on the outside of the auxiliary forming plate 14 are one millimeter smaller than the grooves on the inside of the preliminary forming plate 10. The auxiliary forming plate 14 and the outer side of the preliminary forming plate 10 are provided with three sets of circular grooves of different diameters. By installing the preliminary forming plate 10 alone or installing the auxiliary forming plate 14, six sets of grooves of different diameters can be formed, which facilitates the adjustment of the particle diameter during particle forming.
[0035] refer to Figure 4 and Figure 5 The initial forming plate 10 has three sets of circular grooves inside, with a 15-degree interval between them and a 2-millimeter difference in diameter. The forming funnel 7 has four sets of forming plate adjustment holes 11 at its lower part. Three grooves are formed on the outer side of the forming plate adjustment holes 11, with a 15-degree interval between them. The spring 13 is installed between the lower part of the telescopic column 12 and the auxiliary forming plate 14. By adjusting the position of the telescopic column 12 inside the forming plate adjustment holes 11, the grooves on the outside of the initial forming plate 10 can be aligned with the grooves inside the discharge base 9. At the same time, the three grooves on the outer side of the forming plate adjustment holes 11 allow the telescopic column 12 to be moved and fitted into the three grooves, which can be used to fix the telescopic column 12 inside the grooves and align the medicinal materials inside the initial forming plate 10 with the grooves inside the discharge base 9. The telescopic column 12 can also be squeezed and fixed under the elasticity of the spring 13, which can facilitate the fixing of the initial forming plate 10 after position adjustment.
[0036] refer to Figure 4A cutter 15 is fixedly connected to the lower part of the rotating column 17. The inner side of the cutter 15 can contact the lower part of the preliminary forming plate 10 and the auxiliary forming plate 14. The cutter 15 is fixedly connected to the lower part of the rotating column 17 by the driving device. By adjusting the position of the cutter 15, the lower part of the cutter 15 can be driven to closely adhere to the lower part of the preliminary forming plate 10 and the auxiliary forming plate 14. When the first gear 18 rotates, it can drive the cutter 15 to rotate. At the same time, the cutter 15 cuts the particles formed on the lower part of the preliminary forming plate 10 and the auxiliary forming plate 14, thereby driving the particles to be cut and shaped.
[0037] refer to Figure 3 and Figure 6 A second support plate 22 is installed inside the lower part of the stirring scraper 21. A positioning plate is installed in the middle of the first reduction gear 19 and the second reduction gear 20.

The outer side of the first reduction gear 19 is in close contact with the inner wall of the upper part of the forming funnel 7. By starting the rotating column 17, the first gear 18 is driven to rotate, which in turn drives the first reduction gear 19 to rotate. The first reduction gear 19 drives the second reduction gear 20 to rotate, and the diameter between the first reduction gear 19 and the second reduction gear 20 is not... Similarly, the rotational speed between the second reduction gear 20 and the inner side of the stirring scraper 21 can be adjusted, thereby reducing the rotational speed of the stirring scraper 21 when the rotating column 17 rotates. When the stirring scraper 21 rotates, it is driven to stick tightly to the inner wall of the molding funnel 7, which can scrape off the adhesive material on the inner wall of the molding funnel 7 and avoid the problem of adhesive material clogging the inner wall of the molding funnel 7. At the same time, a second support plate 22 is installed at the lower part of the stirring scraper 21, and the second support plate 22 is pressed tightly against the inside of the molding funnel 7, which can improve the stability of the stirring scraper 21 when it rotates.
[0038] refer to Figure 2 A spiral tube 23 is fixedly connected to the lower part of the rotating column 17. The lower part of the rotating column 17 is movably sleeved inside the discharge base 9. The spiral tube 23 is tightly attached to the inner wall of the lower part of the forming funnel 7. By starting the rotating column 17, the spiral tube 23 is driven to rotate. At the same time, the spiral tube 23 is tightly attached to the inner wall of the lower part of the forming funnel 7, which can drive the rubber material in the upper part of the forming funnel 7 to be squeezed downward and provide power for the rubber material to move downward and be squeezed into shape.
[0039] A method for preparing a particle size adjustable masterbatch preparation device for rubber adhesive production includes the following steps:
[0040] S1: The rubber adhesive liquid state is filled into the interior of the molding funnel 7. At the same time, the rubber adhesive liquid is mixed and stirred in the upper part of the molding funnel 7 and then transported to the lower part of the molding funnel 7. Simultaneously, the rotating column 17 is started, which drives the spiral tube 23 to rotate. The spiral tube 23 drives the rubber adhesive to be squeezed downward and transported downward through the observation door 8.
[0041] S2: Depending on the required particle diameter, an auxiliary forming plate 14 is installed or removed from the lower part of the preliminary forming plate 10, and the telescopic column 12 is rotated to align the corresponding circular discharge hole on the outside of the preliminary forming plate 10 with the groove opened inside the discharge base 9.
[0042] S3: After the discharge diameter is adjusted, when the rotating column 17 rotates, it drives the cutter 15 to closely adhere to the lower part of the auxiliary forming plate 14 or the preliminary forming plate 10. When the rotating column 17 rotates, it drives the rubber adhesive to be conveyed to the lower part through the groove. The rotating column 17 drives the cutter 15 to rotate, which can drive the rubber adhesive squeezed at the lower part of the preliminary forming plate 10 or the auxiliary forming plate 14 to be cut, thus forming granules.
[0043] S4: When the rotating column 17 rotates, it drives the first gear 18 and the first reduction gear 19 to mesh.

When the second reduction gear 20 meshes with the stirring scraper 21, it can reduce the rotation speed of the stirring scraper 21 and clean the rubber adhesive on the inner wall of the molding funnel 7, so as to avoid the rubber adhesive from clogging the inside of the molding funnel 7 and avoid the problem of the stirring scraper 21 rotating too fast and affecting the stirring effect.
[0044] S5: The granular rubber adhesive slides down through the molding funnel 7 into the interior of the upper part of the slide plate 2, and is connected to the pipe inside the cooling liquid flow limiting plate 3, which drives the cooling liquid to flow down through the slide plate 2. The liquid drives the rubber adhesive to cool and form. At the same time, the rubber adhesive particles slide out through the formed particle output groove 5, and the coolant is discharged through the cooling liquid discharge hole 4 at the front end of the formed particle output groove 5, which facilitates the separation between the cooling liquid and the rubber adhesive particles.

S5: The granular rubber adhesive slides down through the molding funnel (7) into the interior of the upper part of the slide plate (2), and is connected to the pipe inside the cooling liquid flow limiting plate (3), which drives the cooling liquid to flow down through the slide plate (2), and the liquid drives the rubber adhesive to cool and form. At the same time, the rubber adhesive particles slide out through the forming particle output groove (5), and the coolant is discharged through the cooling liquid discharge hole (4) at the front end of the forming particle output groove (5), which facilitates the separation between the cooling liquid and the rubber adhesive particles.
