Description

Technical Field

[0001] The invention relates to the technical field of silicone processing, and in particular to a feeding device for liquid silicone processing and a use method thereof. Background Art

[0002] Liquid Silicone Rubber (LSR) is a polymer material with excellent properties. It has good flexibility, high transparency, high and low temperature resistance (it can maintain stable performance in the temperature range of -50℃ to 200℃), chemical stability (tolerance to most chemicals) and biocompatibility.

[0003] Liquid silicone needs to be fed and conveyed during feeding. When the liquid silicone is extruded into the mixing chamber and fully mixed with the color paste and then conveyed to the inside of the mold, due to the certain viscosity of the silicone itself, when the silicone is extruded into the mixing chamber, the flow of the silicone during the conveying process will appear lumpy inside the material chamber due to its own viscosity, resulting in the blocky silicone being difficult to fully contact with the color paste due to the viscosity, which can easily lead to uneven mixing color of the silicone during feeding, affecting the uniformity of the silicone and the color paste during transportation and the feeding quality during feeding.

The liquid silicone mold is installed on the machine discharge pipe, the molding temperature is set, and injection molding is performed to achieve the purpose of transportation.

[0026] The present invention has the following beneficial effects:

[0027] 1. In the present invention, when the motor drives the stirring rod to rotate, the rotation of the stirring rod will drive the sliding sleeve to rotate synchronously, and when the sliding sleeve rotates, it will drive the two long rods and the shaking plate to rotate synchronously. When the long rod rotates, it will slide inside the annular V-groove and, under the guidance of the annular V-groove, the long rod drives the sliding sleeve to slide up and down. When the long rod drives the sliding sleeve to slide upward, when the sliding sleeve slides upward, it will drive the middle part of the vortex spring to slide upward. When the middle part of the vortex spring slides upward after being pushed by the sliding sleeve, the vortex spring will form a conical state at this time. Subsequently, when the sliding sleeve rotates with the stirring rod, it will drive the shaking plate to rotate synchronously. When the shaking plate rotates, the two protruding rods at the bottom thereof will swing back and forth on the surface of the sliding sleeve under the extrusion of the protruding blocks at the top of the fixed cylinder. When the shaking plate swings back and forth, it will drive the vortex spring to swing back and forth. At the same time, when the long rod drives the sliding sleeve to slide up and down, it will drive the vortex spring to swing in ripples. Then, when the silicone falls, the ripples of the vortex spring will shear the falling silicone blocks. At the same time, as the stirring rod rotates rapidly, the sheared silicone will be thrown toward the inner wall of the mixing box. At this time, the falling silicone will be sheared and thrown around and will be dispersed inside the mixing box and fully contact with the color paste and additives, reducing the situation where the silicone is squeezed and becomes sticky blocks due to its own viscosity when entering the mixing box, which is difficult to fully contact with the color paste. This improves the uniformity of the material conveyed outward after mixing in the mixing box, and improves the feeding quality of the feed.

[0028] 2. In the present invention, when the rotation of the sliding sleeve drives the annular plate at the bottom of the spiral spring plate to rotate through the shaking plate, the rotation of the annular plate will drive multiple fixed frames to rotate, and when the fixed frame rotates, it will drive the spring block to rotate synchronously. When the spring block rotates with the sliding sleeve, the rotation of the spring block will slide inside the annular serrated groove through the telescopic plug rod. When the telescopic plug rod slides inside the annular serrated groove, it will be guided by the annular serrated groove to drive the spring block to slide up and down inside the fixed frame. When the spring block slides, it will drive the sliding plate to slide back and forth on the fixed frame through the pushing rod. When the sliding plate slides back and forth, the sliding of the sliding plate will The two rotating plates are driven to slide synchronously. When the sliding plates slide forward, the two rotating plates will be pulled by the semicircular rods to form an open state. When the sliding plates are reset, the rotating plates will be pushed by the two semicircular rods to close. In this way, the rotating plates can be opened and closed back and forth as the sliding plates slide back and forth. When the rotating plates are continuously opened and closed, the spring plates will be driven to beat and squeeze the scattered materials when rotating, thereby promoting the mixing of the materials and the color paste, thereby further improving the situation where the materials are difficult to fully mix with the color paste when they are scattered, thereby further improving the uniformity of the materials during feeding and improving the conveying efficiency.

[0029] 3. In the present invention, when the two rotating plates are opened, the spiral shaft and the gear shaft connected thereto will be driven to slide inside the arc-shaped gear plate. When the gear shafts on the two spiral shafts slide inside the arc-shaped gear plate, the spiral shafts will be driven to rotate. When the two spiral shafts are rotating, the openings at the tops of the spiral shafts will drive the elliptical elastic plate and the two spring rings to slide downward on the surface of the L plate through the raised plate on the elliptical elastic plate when the spiral shafts rotate. At the same time, when the two rotating plates are opened, the L plate and the spring ring will slide in the opposite direction. When the two L plates slide in the opposite direction, they will be moved to the sides in a semicircular manner inside the elliptical elastic plate. The elliptical elastic plate is pushed in the direction of the rod, and the elliptical elastic plate will become deflated and contracted. When the elliptical elastic plate becomes deflated, the sliding of the sliding plate will drive the T-plate to contact the inner wall of the mixing box. Then, when the elliptical elastic plate slides downward, the T-plate will slide and clean on the inner wall of the mixing box, thereby reducing the situation where the material adheres to the inner wall of the mixing box when it splashes with the rapid rotation of the vortex spring, thereby reducing the accumulation of material on the inner wall, reducing the mixing efficiency of the material affected by the adhesion of silicone, and reducing the feeding deviation of the material during transportation caused by the adhesion of the material, thereby improving the stable transportation of the material.

[0065] S2: Adding color paste: Add different color pastes required for the final product to each color paste metering valve 104, and control the proportion through metering valve 107 so that the color paste enters the mixing box 301. According to the requirements of the final product, add different additives to the additive pump 106, and control the proportion through metering valve 2 so that the color paste enters the mixing box 301. The additives can improve the feel, softness, wear resistance and weather resistance of the final product, and can adjust the viscosity of the silicone.

[0066] S3: Mixing and feeding: The motor 401 is then started to drive the stirring rod to evenly mix the rubber component A, the rubber component B, the color paste and the additives in the mixing box 301, and the evenly mixed liquid silicone passes through the material pressure control unit 302 and the release valve 303 to enter the mold through the discharge pipe, and the liquid silicone mold is installed on the machine discharge pipe, the molding temperature is set, and injection molding is performed to achieve the purpose of transportation.

[0067] When in use, the component A and component B rubber materials required for making liquid silicone are added into the material cylinder, and then the hydraulic pump 101 is controlled to insert the pressure plate 203 into the material cylinder, and then the hydraulic pump 202 is driven to make the hydraulic pump piston 204 reciprocate in the liquid cylinder, alternately generating vacuum pressure in the liquid cylinder, so that the liquid silicone in the required proportion is squeezed out and enters the mixing box 301 by opening the one-way valve on the discharge pipe 205, and the different color pastes required for the final product are added to each paste metering valve 104, and the proportion is controlled by the metering valve 107 to allow the paste to enter the mixing box 301. According to the requirements of the final product, different additives are added to the additive pump 106, and the proportion is controlled by the metering valve 2 to allow the paste to enter the mixing box 301. Additives can improve the feel, softness, wear resistance and weather resistance of the final product, and can adjust the viscosity of the silicone. The motor 401 is then started to drive the stirring rod to evenly mix the component A rubber, component B rubber, color paste, additives, etc. in the mixing box 301. The evenly mixed liquid silicone passes through the material pressure control unit 302 and the release valve 303 to enter the mold through the discharge pipe. The liquid silicone mold is installed on the machine discharge pipe, the molding temperature is set, and injection molding is performed to achieve the purpose of transportation.

[0068] When the motor 401 drives the stirring rod to rotate, the rotation of the stirring rod will drive the sliding sleeve 402 to rotate synchronously. When the sliding sleeve 402 rotates, it will drive the two long rods 404 and the shaking plate 403 to rotate synchronously. When the long rod 404 rotates, it will slide inside the annular V-groove 504 and, under the guidance of the annular V-groove 504, the long rod 404 drives the sliding sleeve 402 to slide up and down. When the long rod 404 drives the sliding sleeve 402 to slide upward, when the sliding sleeve 402 slides upward, it will drive the middle part of the vortex spring to slide upward. When the middle part of the vortex spring slides upward after being pushed by the sliding sleeve 402, the vortex spring will form a conical state at this time. Subsequently, when the sliding sleeve 402 rotates with the rotation of the stirring rod, it will drive the shaking plate 403 to rotate synchronously. When the shaking plate 403 rotates, the two protruding rods at the bottom thereof will be squeezed by the protruding blocks at the top of the fixed cylinder 501 in the sliding sleeve 4 02 is swung back and forth. When the swaying plate 403 is swung back and forth, the vortex spring is driven to sway back and forth through the annular plate. At the same time, when the long rod 404 drives the sliding sleeve 402 to slide up and down, the vortex spring is driven to sway in a ripple wave. Then, when the silicone falls, the ripple rocking of the vortex spring will shear the falling silicone block. At the same time, as the stirring rod rotates rapidly, the sheared silicone will be thrown toward the inner wall of the mixing box 301. At this time, the falling silicone will be sheared and thrown around and will be dispersed in the interior of the mixing box 301 and fully contact with the color paste and additives, reducing the situation where the silicone is squeezed and becomes sticky blocks due to its own viscosity when entering the interior of the mixing box 301, which is difficult to fully contact with the color paste. The uniformity of the material being mixed in the mixing box 301 and then transported outward is improved, thereby improving the feeding quality of the feed.

[0069] When the rotation of the sliding sleeve 402 drives the annular plate at the bottom of the spiral spring plate to rotate through the shaking plate 403, the rotation of the annular plate will drive multiple fixed frames 601 to rotate, and when the fixed frame 601 rotates, it will drive the spring block 602 to rotate synchronously. When the spring block 602 rotates with the sliding sleeve 402, the rotation of the spring block 602 will slide inside the annular serrated groove 503 through the telescopic plug rod. When the telescopic plug rod slides inside the annular serrated groove 503, it will be guided by the annular serrated groove 503 to drive the spring block 602 to slide up and down inside the fixed frame 601. When the spring block 602 slides, it will drive the sliding plate 603 to slide back and forth on the fixed frame 601 through the pushing rod 604. When the sliding plate 603 slides back and forth, the sliding The sliding of the movable plate 603 will drive the two rotating plates 701 to slide synchronously. When the sliding plate 603 slides forward, the two rotating plates 701 will be pulled by the semicircular rods 702 to form an open state. When the sliding plate 603 is reset, the rotating plate 701 will be pushed by the two semicircular rods 702 to close. In this way, the rotating plate 701 can be opened and closed back and forth as the sliding plate 603 slides back and forth. When the rotating plate 701 is continuously opened and closed, it will drive the spring plate 703 to slap and squeeze the scattered materials when rotating, thereby promoting the mixing of the materials and the color paste, and further improving the situation where the materials are difficult to fully mix with the color paste when they are scattered, thereby further improving the uniformity of the materials during feeding and improving the conveying efficiency.

[0070] When the two rotating plates 701 are opened, the spiral shaft 704 and the gear shaft connected thereto will be driven to slide inside the arc-shaped gear plate 801. When the gear shafts on the two spiral shafts 704 slide inside the arc-shaped gear plate 801, the spiral shaft 704 will be driven to rotate. When the two spiral shafts 704 are rotating, the openings at the tops of the spiral shafts 704 will drive the elliptical elastic plate 804 and the two spring rings 803 to slide downward on the surface of the L plate 802 through the raised plates on the elliptical elastic plate 804 when the spiral shaft 704 rotates. At the same time, when the two rotating plates 701 are opened, they will slide oppositely through the L plate 802 and the spring ring 803. When the two L plates 802 slide oppositely, they will be aligned inside the elliptical elastic plate 804. It pushes the semicircular rod 702 on both sides, and the elliptical elastic plate 804 will shrink. When the elliptical elastic plate 804 shrinks, the sliding plate 603 will drive the T-plate 805 to contact the inner wall of the mixing box 301. Then, when the elliptical elastic plate 804 slides downward, the T-plate 805 will slide and clean on the inner wall of the mixing box 301, thereby reducing the adhesion of materials to the inner wall of the mixing box 301 when the materials are splashed with the rapid rotation of the vortex spring, thereby reducing the accumulation of materials on the inner wall, reducing the mixing efficiency of materials affected by the adhesion of silicone, and reducing the feeding deviation of materials during transportation caused by the adhesion of materials, thereby improving the stable transportation of materials.
