Description

Technical Field

[0001] The utility model relates to the technical field of silicone rubber production equipment, in particular to an automatic mixing and stirring device for silicone rubber production. Background Art

[0002] Silicone rubber is a polymer material with excellent performance and a wide range of applications. Silicone rubber products are manufactured using silicone and rubber as their primary raw materials. With technological advancements and the development of industrialization, the application areas of silicone rubber products are constantly expanding. During the production and processing of silicone rubber products, multiple raw materials must be mixed using a mixing and stirring device.

[0003] After searching, the Chinese patent "A mixing silicone rubber production device" authorization announcement number "CN220482200U" drives the movable stirring mechanism to rotate as a whole through the first output motor to stir and mix the silicone rubber, and the movable stirring mechanism and the fixed cleaning mechanism cooperate with each other to scrape off the silicone rubber remaining on the surface of the movable stirring mechanism, and the external water pipe is extended into the inner side of the feeding port for cleaning. At the same time, when the silicone rubber is produced, the movable stirring mechanism can stir and mix the silicone rubber. The overall structure is simple and the operation is convenient and quick.

[0004] Although the above application can clean the silicone rubber on the surface of the stirring mechanism, some of the raw materials will still adhere to the inner wall of the stirring barrel after the raw materials are unloaded. The above solution cannot clean the inner wall of the stirring barrel, thereby affecting the cleaning effect.

[0005] Therefore, an automatic mixing and stirring device for silicone rubber production is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide an automatic mixing and stirring device for silicone rubber production in order to solve the above-mentioned problem, thereby improving the problem that after the material is unloaded, some raw materials will still adhere to the inner wall of the mixing barrel, and the above-mentioned solution cannot clean the inner wall of the mixing barrel, thereby affecting the cleaning effect.

[0007] The utility model achieves the above-mentioned object through the following technical solutions: an automatic mixing and stirring device for silicone rubber production, comprising: a mixing barrel, the inner wall of which is rotatably connected to a rotating shaft, the top end of which passes through the mixing barrel, a plurality of stirring rods being mounted on the surface of the rotating shaft, and a cleaning mechanism being provided inside the mixing barrel;

[0008] In which, the cleaning mechanism includes a cleaning ring slidably connected to the inner wall of the mixing barrel, and an angle is formed between the surface of the cleaning ring and the horizontal plane. An electric push rod is installed on the top of the mixing barrel, and the bottom end of the electric push rod passes through the interior of the mixing barrel and is fixedly connected to the top of the cleaning ring. The inner wall of the rotating shaft is rotatably connected to a round rod, and the top and bottom ends of the round rod both pass through the rotating shaft. Two connecting rods are fixedly connected to the lower end of the surface of the round rod, and a sliding rod is slidably connected to the surface of the connecting rod. A scraper is fixedly connected to one side of the sliding rod, and one side of the scraper is in contact with the surface of the cleaning ring.

[0009] Preferably, the cleaning mechanism further comprises a mounting rod fixedly connected to the top of the cleaning ring, the upper end of the surface of the round rod being provided with a spiral groove, the inner wall of the spiral groove being slidably connected to a driving block, the surface of the round rod being slidably connected to a circular ring, the inner wall of the circular ring being fixedly connected to the surface of the driving block, and the surface of the circular ring being fixedly connected to the other end of the mounting rod. The movement of the cleaning ring facilitates the synchronous rotation of the round rod, and the connection rod and the sliding rod facilitate the rotation of the scraper against the surface of the cleaning ring, thereby scraping off the raw materials adhering to the surface of the cleaning ring during the cleaning process.

[0010] Preferably, a cleaning plate is fixedly connected to the bottom end of the round rod, and the vertical cross-section of the cleaning plate is an isosceles triangle, which is conducive to cleaning the inner bottom wall of the mixing barrel and ensures the cleaning effect of the mixing barrel.

[0011] Preferably, the inner wall of the cleaning ring is provided with an annular groove, the inner wall of which is slidably connected to a slider, the bottom end of which is fixedly connected to the top end of the slide rod. This helps ensure that when the slide rod drives the scraper to rotate, the scraper always contacts the surface of the cleaning ring, thereby ensuring the cleaning effect of the scraper.

[0012] Preferably, an annular tube is fixedly connected to the top of the cleaning ring, and two groups of nozzles are connected to the surface of the annular tube. The cleaning ring drives the annular tube and the two groups of nozzles to move downward synchronously, which is conducive to improving the flushing effect of the interior of the mixing barrel. Under the action of the two groups of nozzles, the inner wall of the mixing barrel and the stirring rod are facilitated to be flushed simultaneously.

[0013] Preferably, the inner wall of the cleaning ring is rotatably connected to a protective ring, and the inner wall of the protective ring is fixedly connected to the surface of the slider, which is beneficial for protecting the annular groove and ensuring the stability of the connection between the slider and the annular groove.

[0014] Preferably, a motor is fixedly connected to the top of the mixing barrel, and the output shaft of the motor and the surface of the rotating shaft are both fixedly connected with bevel gears, and the two bevel gears are meshed and connected, which is conducive to ensuring the normal operation of the device.

[0015] The beneficial effects of the utility model are:

[0016] 1. In the above-mentioned cleaning mechanism, an electric push rod is used to push the cleaning ring downward, which is conducive to the cleaning ring to scrape and clean the raw materials adhering to the inner wall of the mixing barrel, thereby improving the cleaning effect of the mixing barrel. Under the action of the mounting rod, the circular ring, the driving block and the spiral groove, the running trend of the cleaning ring is used to drive the circular rod to rotate synchronously, and the connecting rod and the sliding rod are used to drive the scraper to rotate in contact with the surface of the cleaning ring, thereby scraping off the raw materials adhering to the surface of the cleaning ring during the cleaning process, preventing the raw materials scraped by the cleaning ring from being retained on its surface during the cleaning process, thereby improving the cleaning effect of the cleaning ring on the inner wall of the mixing barrel;

[0017] 2. When the cleaning ring moves downward, under the action of the slider and the annular groove, it is helpful to ensure that when the slide rod drives the scraper to rotate, the scraper always fits with the surface of the cleaning ring, ensuring the cleaning effect of the scraper.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] When implementing: Figure 1-5 As shown, an automatic mixing and stirring device for silicone rubber production comprises: a mixing barrel 1, the inner wall of the mixing barrel 1 is rotatably connected to a rotating shaft 2, the top end of the rotating shaft 2 passes through the mixing barrel 1, a plurality of stirring rods 3 are installed on the surface of the rotating shaft 2, and a cleaning mechanism 4 is provided inside the mixing barrel 1; wherein, the cleaning mechanism 4 comprises a cleaning ring 41 slidably connected to the inner wall of the mixing barrel 1, the surface of the cleaning ring 41 forms an angle with the horizontal plane, an electric push rod 42 is installed on the top of the mixing barrel 1, the bottom end of the electric push rod 42 passes through the interior of the mixing barrel 1 and is fixedly connected to the top of the cleaning ring 41, the inner wall of the rotating shaft 2 is rotatably connected to a round rod 43, the top and bottom ends of the round rod 43 both pass through the rotating shaft 2, and the lower end of the surface of the round rod 43 is fixedly connected to two connecting rods 44, the surface of the connecting rod 44 is slidably connected to a sliding rod 45, one side of the sliding rod 45 is fixedly connected to a scraper 46, and one side of the scraper 46 is in contact with the surface of the cleaning ring 41.

[0026] A feed port is provided at the top of the mixing barrel 1, and a protective cover is provided at the top of the feed port. A discharge port is provided at the bottom of the mixing barrel 1. When performing a stirring operation, the discharge port can be sealed by a sealing cover.

[0027] like Figure 2 and Figure 4 As shown, the cleaning mechanism 4 also includes a mounting rod 48 fixedly connected to the top of the cleaning ring 41, a spiral groove 47 is provided on the upper end of the surface of the round rod 43, and the inner wall of the spiral groove 47 is slidably connected to the driving block 410, and the surface of the round rod 43 is slidably connected to the ring 49, the inner wall of the ring 49 is fixedly connected to the surface of the driving block 410, and the surface of the ring 49 is fixedly connected to the other end of the mounting rod 48.

[0028] When performing the cleaning operation, the electric push rod 42 is started by the controller to push the cleaning ring 41 downward. The upper end of the surface of the cleaning ring 41 contacts the inner wall of the mixing barrel 1. During the downward movement of the cleaning ring 41, the inner wall of the mixing barrel 1 will be cleaned, and the mounting rod 48 will be driven to move downward synchronously, thereby pulling the circular ring 49 to drive the driving block 410 to move downward synchronously. The driving block 410 will slide downward along the path of the spiral groove 47, thereby driving the circular rod 43 to rotate, thereby driving the two connecting rods 44 to rotate synchronously, and under the action of the corresponding sliding rod 45, the two scrapers 46 are driven to adhere to the surface of the cleaning ring 41 for synchronous rotation, thereby scraping off the raw materials adhered to the surface of the cleaning ring 41 during the cleaning process.

[0029] like Figure 5 As shown, the bottom end of the round rod 43 is fixedly connected to a cleaning plate 411, and the vertical cross-section of the cleaning plate 411 is an isosceles triangle.

[0030] The bottom end of the cleaning plate 411 contacts the inner bottom wall of the mixing barrel 1 , and when the round rod 43 rotates, the cleaning plate 411 is driven to rotate synchronously to clean the inner bottom wall of the mixing barrel 1 .

[0031] like Figure 3 As shown, an annular groove 412 is formed on the inner wall of the cleaning ring 41 , a slider 413 is slidably connected to the inner wall of the annular groove 412 , and the bottom end of the slider 413 is fixedly connected to the top end of the slide rod 45 .

[0032] When the cleaning ring 41 moves downward, it will drive the slider 413 to move downward synchronously, so that the slide bar 45, the scraper 46 and the cleaning ring 41 move downward at the same speed, so that the scraper 46 always fits the inclined surface of the cleaning ring 41 during the rotation process.

[0033] like Figure 3 As shown, the top of the cleaning ring 41 is fixedly connected to an annular tube 414 , and the surface of the annular tube 414 is connected to two groups of nozzles 415 .

[0034] Both groups of nozzles 415 are arranged at an angle, with the opening direction of one group of nozzles 415 facing the inner wall of the mixing barrel 1, and the opening direction of the other end nozzle 415 facing the stirring rod 3. The upper end of the surface of the annular tube 414 is connected with a connecting tube. In the initial state, the connecting tube passes through the mixing barrel 1, and a through hole larger than the diameter of the connecting tube is opened at the top of the mixing barrel 1. When cleaning, the connecting tube is connected to the external water pipe. The downward movement of the cleaning ring 41 will drive the annular tube 414 to move downward synchronously, and pull the connected water pipe downward at the same time. At this time, the two groups of nozzles 415 will simultaneously spray water to flush the inner wall of the mixing barrel 1 and the stirring rod 3. The stirring rod 3 is set to be cylindrical so that the silicone retained on the surface can be better removed under the action of the aqueous solution.

[0035] like Figure 3 As shown, the inner wall of the cleaning ring 41 is rotatably connected to a protective ring 416, and the inner wall of the protective ring 416 is fixedly connected to the surface of the slider 413. The surface of the protective ring 416 fits the inner wall of the cleaning ring 41 to shield the annular groove 412.

[0036] like Figure 2 As shown, a motor 22 is fixedly connected to the top of the mixing barrel 1 , and a bevel gear 21 is fixedly connected to the output shaft of the motor 22 and the surface of the rotating shaft 2 , and the two bevel gears 21 are meshed and connected.

[0037] When the raw materials are mixed, the motor 22 is started by the controller, and the output shaft of the motor 22 drives one of the bevel gears 21 to rotate, and the other bevel gear 21 drives the rotating shaft 2 to rotate, thereby driving the stirring rod 3 to rotate and mix the raw materials.

[0038] When the utility model is in use, the raw materials are put into the mixing barrel 1 through the feed port, and the motor 22 is started by the controller. Under the action of the two bevel gears 21, the rotating shaft 2 is driven to rotate, thereby driving the stirring rod 3 to rotate to mix and stir the raw materials. After the mixing is completed, the raw materials are discharged through the discharge port at the bottom of the mixing barrel 1.

[0039] When cleaning the interior of the mixing barrel 1 after the unloading is completed, first connect the upper end connecting pipe of the annular tube 414 to the external water pipe, so that water flows through the two sets of nozzles 415 to spray out and rinse the interior of the mixing barrel 1. At the same time, the electric push rod 42 is activated by the controller to push the cleaning ring 41 downward to scrape and clean the raw materials adhering to the inner wall of the mixing barrel 1. At the same time, the cleaning ring 41 will drive the annular tube 414 to move downward synchronously. At this time, the two sets of nozzles 415 will simultaneously spray water along the downward movement path of the cleaning ring 41 to rinse the inner wall of the mixing barrel 1 and the stirring rod 3. When the cleaning ring 41 moves downward, the slider 413 drives the slide bar 45 and the scraper 46 to move downward synchronously, and at the same time drives the mounting rod 48 to pull the ring 49 downward, thereby causing the driving block 410 to move downward synchronously. At this time, the driving block 410 slides downward along the path of the spiral groove 47, thereby driving the round rod 43 to rotate, and driving the two connecting rods 44 to rotate synchronously. Under the action of the corresponding slide bar 45, the two scrapers 46 are driven to rotate synchronously in contact with the surface of the cleaning ring 41, thereby scraping off the raw materials adhered to the surface of the cleaning ring 41 during the cleaning process.

[0040] It should be noted that the electric push rod 42, motor 22, etc. in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the electric push rod 42 and motor 22 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0041] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
