Description

Technical Field

[0001] This utility model relates to the field of silicone rubber technology, and more specifically, to a silicone rubber compounding production equipment. Background Technology

[0002] Silicone rubber is a type of rubber whose main chain consists of alternating silicon and oxygen atoms, with two organic groups typically attached to each silicon atom. Ordinary silicone rubber is mainly composed of siloxane chains containing methyl groups and a small amount of vinyl groups. The introduction of phenyl groups can improve the high and low temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups can improve its temperature and oil resistance. Silicone rubber has good low-temperature resistance, generally still functioning at -55°C. Reactors are widely used in petroleum, chemical, rubber compounding, pesticide, dye, pharmaceutical, and food industries as pressure vessels to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Reactors are also used in the production of rubber compounds.

[0003] In the compounding production process of silicone rubber, a reaction vessel is also required. During the processing, raw materials or ingredients need to be put into the reaction vessel for reaction. However, in some existing reaction vessels, due to the high viscosity of the compounded rubber, it is easy for the compounded rubber to stick to the inner wall of the reaction vessel after use, making it difficult to clean. If this compounded rubber remains on the inner wall of the reaction vessel for a long time, it will not only reduce the internal space of the reaction vessel, but also affect the normal use of the reaction vessel. Therefore, we provide a silicone rubber compounding production equipment. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 5 A silicone rubber compounding production device includes a reactor body 1. A first scraper 2 is slidably connected inside the reactor body 1. A second scraper 3 is fixedly connected to the bottom of the first scraper 2. A first rotating shaft 4 is fixedly connected to the top of the first scraper 2. A lead screw 5 is sleeved on the outside of the first rotating shaft 4. The first rotating shaft 4 and the lead screw 5 are rotatably connected. The lead screw 5 vertically penetrates the reactor body 1 and extends to the outside of the reactor body 1. The lead screw 5 is slidably connected to the reactor body 1. The first scraper 2 has an annular structure and is used to scrape off residual rubber above the reactor body 1. The second scraper 3 is inclined and is used to scrape off residual rubber below the reactor body 1. A bushing is sleeved on the outside of the lead screw 5. 6. The bushing 6 is rotatably connected to the reactor body 1, and the lead screw 5 is threadedly connected to the bushing 6. The lead screw 5 has a limiting groove 7 inside, and a limiting block 8 is slidably connected inside the limiting groove 7. There are two sets of limiting grooves 7 and limiting blocks 8, which are symmetrically distributed on both sides of the lead screw 5. The limiting grooves 7 and limiting blocks 8 limit the lead screw 5, so that the lead screw 5 can only move up and down in a straight line and will not rotate. When the bushing 6 rotates, the bushing 6 can drive the lead screw 5 to move up and down. The limiting block 8 is fixedly connected to the reactor body 1. The top of the reactor body 1 is provided with a transmission mechanism 9, which can drive the first scraper 2 and the second scraper 3 to rotate and move up and down.

[0016] Furthermore, the transmission mechanism 9 includes a mounting plate 10, which is fixedly connected to the reactor body 1. A second rotating shaft 11 is rotatably connected between the mounting plate 10 and the reactor body 1. A first gear 12 is sleeved on the outer side of the second rotating shaft 11 near the reactor body 1. The first gear 12 is fixedly connected to the second rotating shaft 11. A second gear 13 is sleeved on the outer side of the bushing 6. The second gear 13 is fixedly connected to the bushing 6 and meshes with the first gear 12. A protective shell (not shown in the attached figure) needs to be installed between the second gear 13 and the first gear 12. The protective shell will not affect the use of the lead screw 5, thereby avoiding corrosion of the gears by possible residual liquids and extending the service life. The mounting plate 10 is an inverted L-shaped structure. The second rotating shaft 11 can drive the bushing 6 to rotate through the first gear 12 and the second gear 13.

[0017] Furthermore, a groove 14 is provided inside the first rotating shaft 4, and a slide rod 15 is slidably connected inside the groove 14. The slide rod 15 is rotatably connected to the mounting plate 10. The cross-sections of the groove 14 and the slide rod 15 are both square structures. The outer side wall of the slide rod 15 fits against the inner side wall of the groove 14. The first rotating shaft 4 is sleeved on the outside of the slide rod 15, and the first rotating shaft 4 can move up and down outside the slide rod 15. Since the cross-sections of the groove 14 and the slide rod 15 are both square structures, the rotation of the slide rod 15 can drive the first rotating shaft 4 to rotate as well, thereby driving the first scraper 2 and the second scraper 3 to rotate through the first rotating shaft 4.

[0018] Furthermore, a first servo motor 16 is fixedly connected to the top of the mounting plate 10 and above the slide rod 15. The output shaft of the first servo motor 16 vertically passes through the mounting plate 10 and extends into the interior of the mounting plate 10. The output shaft of the first servo motor 16 is rotatably connected to the mounting plate 10. The output end of the first servo motor 16 is fixedly connected to the slide rod 15. The first servo motor 16 directly drives the slide rod 15 to rotate. The slide rod 15, in conjunction with the slide groove 14, drives the first rotating shaft 4 to rotate. The first rotating shaft 4 drives the first scraper 2 and the second scraper 3 to rotate, and the second scraper 3 is used to scrape off the residual adhesive at the lower position of the reactor body 1.

[0019] Furthermore, a second servo motor 17 is fixedly connected to the top of the mounting plate 10 and above the second rotating shaft 11. The output shaft of the second servo motor 17 vertically passes through the mounting plate 10 and extends into the interior of the mounting plate 10. The output shaft of the second servo motor 17 is rotatably connected to the mounting plate 10. The output end of the second servo motor 17 is fixedly connected to the second rotating shaft 11. The second servo motor 17 directly drives the second rotating shaft 11 to rotate. The second rotating shaft 11 drives the bushing 6 to rotate through the first gear 12 and the second gear 13. The bushing 6 drives the lead screw 5 to move up and down. The lead screw 5 drives the first scraper 2 and the second scraper 3 to move up and down through the first rotating shaft 4. The first scraper 2 is used to scrape off the residual adhesive above the inner wall of the reactor body 1.

[0020] Furthermore, the mounting plate 10 is externally fixedly connected to a control panel 18. The first servo motor 16 and the second servo motor 17 are both electrically connected to the control panel 18. The electrical equipment is powered by an external power source and controlled by the control panel 18. When the first servo motor 16 is started, it can drive the first scraper 2 and the second scraper 3 to rotate in both directions. When the second servo motor 17 is started, it can drive the first scraper 2 and the second scraper 3 to move up and down.

[0021] The usage steps of this utility model are as follows: When using this silicone rubber mixing production equipment, to clean and scrape the residual adhesive on the inner wall of the reactor body 1, the second servo motor 17 is started through the control panel 18. The second servo motor 17 directly drives the second rotating shaft 11 to rotate. The second rotating shaft 11 drives the bushing 6 to rotate through the first gear 12 and the second gear 13. Because the lead screw 5 is limited by the limiting groove 7 and the limiting block 8, when the bushing 6 rotates, the bushing 6 will drive the lead screw 5 to move up and down. The lead screw 5 drives the first scraper 2 and the second scraper 3 to move up and down as a whole through the first rotating shaft 4. Thus, the first scraper 2 scrapes and cleans the residual adhesive at the upper position of the inner wall of the reactor body 1. Then, the lead screw 5 is controlled to move downward until the second scraper 3... After the second servo motor 17 is turned off and the first servo motor 16 is started, the first servo motor 16 directly drives the slide rod 15 to rotate. Since the cross-section of the slide rod 15 and the slide groove 14 are both square structures, the slide rod 15 can drive the first rotating shaft 4 to rotate through the slide groove 14. In turn, the first rotating shaft 4 drives the first scraper 2 and the second scraper 3 to rotate. Finally, the second scraper 3 is used to scrape and clean the residual glue at the lower part of the inner wall of the reactor body 1. When the second servo motor 17 is started and drives the first scraper 2 and the second scraper 3 to move up and down, the first servo motor 16 can also be started, so that the first scraper 2 can move up and down as a whole and rotate at the same time, thereby improving the scraping effect of the first scraper 2 on the residual glue.
