Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, specifically to a rubber mixing equipment for rubber processing. Background Technology

[0002] Rubber mixing equipment is an indispensable tool in the rubber processing process. It is used for plasticizing and mixing rubber, as well as preparing semi-finished rubber products. It mainly includes two categories: open mixing mills (open mills) and closed mixing mills (internal mixers). Open mills are used for hot refining, sheeting, breaking, plasticizing, and mixing of rubber, while internal mixers are used for plasticizing and mixing rubber. They each have different working principles, uses, and characteristics, but both play a vital role in the rubber processing process.

[0003] Patent CN221561863U discloses a rubber mixing equipment for rubber processing, including a processing box. A stirring element is rotatably connected inside the processing box. A scraper ring, sliding axially along the stirring element, is provided inside the processing box. The scraper ring is circumferentially arranged along the inner wall of the processing box. The stirring element is located inside the scraper ring, and the outer side of the scraper ring contacts the inner wall of the processing box. The processing box includes a rotation drive assembly for driving the stirring element to rotate and a movement drive assembly for driving the scraper ring to slide within the processing box. The annular scraper ring is positioned at the top during mixing, effectively preventing rubber residue from remaining on the scraper ring and avoiding uneven mixing of the rubber.

[0004] Although the above-mentioned device prevents adhesive residue by using a ring-shaped scraper, it still has the following shortcomings:

[0005] Temperature is a critical factor in rubber processing. Different types of rubber require different mixing temperatures, ranging from 40 to 170 degrees Celsius, but all require a stable temperature environment. The aforementioned equipment lacks control over the mixing temperature, which can lead to problems with the quality of the rubber mats and the performance of the finished products. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a rubber mixing equipment for rubber processing, which can precisely control the processing temperature during the rubber mixing process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rubber mixing equipment for rubber processing, including a mixing box, a feed inlet on the top surface of the mixing box, a discharge outlet on the bottom surface of the mixing box, a mixing assembly inside the mixing box, a scraping assembly on the top surface of the mixing box, an annular heating cylinder on the outside of the mixing box, a heating ring on the inner wall of the annular heating cylinder, a control panel connected to the heating ring on the outside of one end of the annular heating cylinder, and a temperature sensor on the bottom surface of the control panel.

[0008] Furthermore, the rubber mixing assembly includes a rubber mixing drive motor mounted on the top surface of the rubber mixing tank, a rubber mixing drive rod connected to the bottom surface of the rubber mixing drive motor, and a spiral stirring blade mounted on the rubber mixing drive rod located inside the rubber mixing tank.

[0009] Furthermore, the scraping assembly includes a scraping annular plate disposed on the top surface inside the rubber mixing chamber. A lead screw is fixedly connected to the end of the scraping annular plate away from the feed inlet. A threaded gear is rotatably connected to the lead screw at the top surface of the rubber mixing chamber. A drive gear is connected to the threaded gear. A scraping drive motor is disposed on the drive gear. A limiting frame for fixing the drive gear and the drive gear is disposed on the top surface of the rubber mixing chamber. A protective shell for wrapping the rubber mixing assembly and the scraping assembly is disposed on the top surface of the rubber mixing chamber.

[0010] Furthermore, the bottom surface of the adhesive scraping ring plate is inclined inward.

[0011] Furthermore, there are two heating rings and three temperature sensors, which are respectively located at the top, bottom and middle of the heating rings.

[0012] Furthermore, an oil stirring motor is installed on the top surface of the annular heating cylinder at the end away from the control panel. The bottom surface of the stirring motor is connected to an oil stirring rod installed inside the annular heating cylinder, and a motor housing is installed outside the oil stirring motor.

[0013] Furthermore, the annular heating cylinder has observation windows on its other two sides.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By installing an annular heating cylinder on the outside of the rubber mixing tank and using an oil bath to heat the tank, operators can adjust the power of the heating ring according to real-time conditions with the help of a control panel and temperature sensor, thus ensuring a stable and appropriate temperature during the rubber mixing process and guaranteeing the stability of the process. By installing a through-hole scraping component on the top surface of the rubber mixing tank, residual rubber on the inner wall of the tank can be scraped to the bottom, preventing rubber residue from causing corrosion or wear to the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figures 1 to 5 As shown, a rubber mixing equipment for rubber processing includes a mixing tank 1, a feed inlet 101 on the top surface of the mixing tank 1, a discharge outlet 102 on the bottom surface of the mixing tank 1, a mixing assembly 2 inside the mixing tank 1, a through scraping assembly 3 on the top surface of the mixing tank 1, an annular heating cylinder 4 on the outside of the mixing tank 1, a heating ring 401 on the inner wall of the annular heating cylinder 4, a control panel 402 connected to the heating ring 401 on the outer side of one end of the annular heating cylinder 4, and a temperature sensor 403 on the inner side of the control panel 402.

[0024] like Figure 1 As shown, the rubber mixing equipment in this utility model is structurally similar to existing rubber mixing equipment. For example, patent CN221561863U discloses a rubber mixing equipment for rubber processing. The main improvement of this utility model is that it can precisely control the processing temperature during the rubber mixing process. Figures 1 to 5As shown, the rubber mixing equipment of this utility model, during rubber mixing, first controls the heating ring 401 to heat the oil bath agent in the annular heating cylinder 4 according to the type of rubber via the control panel 402. Simultaneously, driven by the oil agent stirring motor 404, the oil agent stirring rod 405 also stirs, accelerating the uniformity of the oil bath agent temperature. Once the temperatures transmitted by all temperature sensors 403 are basically consistent and suitable, the rubber compound is placed into the mixing tank 1 through the feed inlet 101. At this time, the rubber mixing drive motor 201 is activated, and the spiral agitator on the rubber mixing drive rod 202... The mixing blade 203 will stir the rubber compound. After stirring, it will fall out from the discharge port 102 for collection by the staff. After the rubber is mixed, the scraper drive motor 305 will drive the drive gear 304 to rotate together with the threaded gear 303. The threaded gear 303 can pull the screw 302 through the thread at the center, so that the screw 302 and the scraper ring plate 301 fixedly connected thereto will move up and down, thereby scraping the inner wall of the rubber mixing box 1, so that the residual rubber on the inner wall of the rubber mixing box 1 will be scraped off, avoiding the residual rubber from causing corrosion or wear to the equipment.

[0025] like Figure 4 As shown, the rubber mixing assembly 2 includes a rubber mixing drive motor 201 disposed on the top surface of the rubber mixing tank 1, a rubber mixing drive rod 202 connected to the bottom surface of the rubber mixing drive motor 201, and a spiral stirring blade 203 disposed on the part of the rubber mixing drive rod 202 located inside the rubber mixing tank 1.

[0026] Specifically, driven by the rubber mixing drive motor 201, the rubber entering from the feed inlet 101 is stirred by the spiral stirring blades 203 on the rubber mixing drive rod 202. The rubber compound is dispersed and uniformly mixed due to shearing action, thereby achieving the purpose of rubber mixing.

[0027] like Figure 4 and Figure 5 As shown, the scraping assembly 3 includes a scraping annular plate 301 disposed on the top surface inside the rubber mixing box 1. A lead screw 302 is fixedly connected to the end of the scraping annular plate 301 away from the feed inlet 101. A threaded gear 303 is rotatably connected to the lead screw 302 at the top surface of the rubber mixing box 1. A drive gear 304 is connected to the teeth of the threaded gear 303. A scraping drive motor 305 is disposed on the drive gear 304. A limiting frame 306 is disposed on the top surface of the rubber mixing box 1 to fix the threaded gear 303 and the drive gear 304. A protective shell 103 is disposed on the top surface of the rubber mixing box 1 to cover the rubber mixing assembly 2 and the scraping assembly 3.

[0028] like Figure 4 As shown, the bottom surface of the adhesive scraping ring plate 301 is inclined inward.

[0029] Specifically, to prevent rubber residue from remaining on the inner wall of the rubber mixing box 1, the drive gear 304, driven by the scraper drive motor 305, will rotate the threaded gear 303. The threaded gear 303 can pull the lead screw 302 through the thread at its center, causing the lead screw 302 and the scraper ring plate 301, which is fixedly connected thereto, to move up and down, thereby scraping the inner wall of the rubber mixing box 1. The scraper ring plate 301, with its bottom inclined inward, can improve scraping efficiency and also facilitates the scraped residue to fall off the scraper ring plate 301, preventing rubber residue from remaining on the scraper ring plate 301.

[0030] like Figure 2 and Figure 3 As shown, there are two heating rings 401 positioned at the top and bottom, and three temperature sensors 403 positioned at the top, bottom, and middle of the heating rings 401. This arrangement allows for better heating of the oil bath liquid, ensuring consistent temperature across the oil bath liquid. Furthermore, the three temperature sensors 403 can record the temperature at different locations on the oil bath liquid, helping operators to better adjust the heating rings 401 and ensure the stability of the oil bath liquid's temperature changes.

[0031] like Figure 2 and Figure 3 As shown, an oil stirring motor 404 is provided on the top surface of the annular heating cylinder 4 at the end away from the control panel 402. The bottom surface of the oil stirring motor 404 is connected to an oil stirring rod 405 provided inside the annular heating cylinder 4. A motor housing 406 is provided outside the oil stirring motor 404.

[0032] Specifically, driven by the oil stirring motor 404, the oil stirring rod 405 inside the annular heating cylinder 4 will stir the oil bath liquid, so that the oil bath liquid alternates between up and down and the temperature is uniform.

[0033] like Figure 2 and Figure 3 As shown, the annular heating cylinder 4 is provided with observation windows 407 on both sides. This arrangement allows for real-time observation of the oil bath liquid content inside the annular heating cylinder 4, facilitating the addition and replacement by staff.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
