Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing, in particular to a rubber mixing device for producing automobile seals. Background Technique

[0002] With the development of society, the progress of the times, and the popularization of various means of transportation, automobiles have entered thousands of households due to their convenient and compact characteristics and have gradually become one of the main means of transportation indispensable for people's daily travel. Most automobile seals are made of rubber or plastic. Due to different production methods, the performance of automobile seals is also different. Therefore, it is necessary to carry out solid refining of rubber into colloid.

[0003] Most of the existing rubber mixing devices use the hot melting method to mix rubber. This method requires a large amount of heat energy, and there is uneven heating during the stirring and mixing process, resulting in defects such as low elasticity of the colloid and easy aging and breakage of automobile sealing strips, thus shortening the service life of the sealing strips. And because the colloid is in a viscous state during the refining process, the existing rubber mixing barrels are generally cylindrical, which is not convenient for quickly discharging the colloid. Therefore, we propose a rubber mixing device for producing automobile seals to solve the above problems. Content of the Utility Model

[0006] (2) Technical Solution

[0007] To achieve the above object, the utility model provides the following technical solution: A rubber mixing device for producing automobile seals includes a rubber mixing bin. A rotating shaft is longitudinally rotatably installed inside the rubber mixing bin, and a plurality of stirring mechanisms are arranged on the outer side wall of the rotating shaft;

[0008] The stirring mechanism includes a stirring plate. Two guard plates are symmetrically and fixedly installed on the outer side wall of the rotating shaft. The two guard plates are rotatably connected to the stirring plate through a connecting shaft. A limiting plate is fixedly installed on the outer side wall of the rotating shaft, and the bottom end of the limiting plate is attached to the top end of the stirring plate. A guiding plate is fixedly installed at the top end of the stirring plate. Two feeding doors are symmetrically communicated and arranged at the top end of the rubber mixing bin, and two discharge doors are symmetrically communicated and installed at the bottom end of the rubber mixing bin.

[0024] Embodiment

[0025] Please refer to Figures 1-5 , a rubber mixing device for producing automotive seals, including a rubber mixing bin 1. A rotating shaft 2 is longitudinally and rotatably installed inside the rubber mixing bin 1, and a plurality of stirring mechanisms are arranged on the outer side wall of the rotating shaft 2; the stirring mechanism includes a stirring plate 5, and two guard plates 3 are symmetrically and fixedly installed on the outer side wall of the rotating shaft 2;

[0026] Please refer to Figures 1-5 , at one end of each stirring plate 5 away from the rotating shaft 2, a scraping plate 10 is fixedly installed. By installing the scraping plate 10, it is convenient to scrape the colloid adhered to the inner side wall of the rubber mixing bin 1. A plurality of stirring columns 11 are fixedly installed on the outer side wall of each stirring plate 5. By installing the stirring columns 11, it is convenient for the stirring plate 5 to stir the colloid. The two guard plates 3 are rotatably connected to the stirring plate 5 through a connecting shaft 4. A limiting plate 6 is fixedly installed on the outer side wall of the rotating shaft 2, and the bottom end of the limiting plate 6 fits with the top end of the stirring plate 5. A guiding plate 7 is fixedly installed at the top end of the stirring plate 5. Two feeding doors 8 are symmetrically communicated and arranged at the top end of the rubber mixing bin 1, and two discharging doors 9 are symmetrically communicated and installed at the bottom end of the rubber mixing bin 1. For this rubber mixing device for producing automotive seals, while the rotating shaft 2 rotates, the stirring plate 5 is driven by the connecting shaft 4 and the guard plates 3 to adjust the angle. Through different angles of rotation of the stirring plate 5, the colloid at different depths inside the rubber mixing bin 1 is stirred. Through continuous contact between the guiding plate 7 at the top end of the stirring plate 5 and the colloid, the guiding plate 7 stirs the colloid at different depths downward, improving the rapid stirring operation of the device on the colloid inside the rubber mixing bin 1, thereby improving the efficiency of the device for stirring and mixing rubber, facilitating the rapid discharge of the colloid through the discharging door 9 from the inside of the rubber mixing bin 1, and improving the practicability.

[0027] Please refer to Figure 1 , it should also be noted that a motor 12 is fixedly installed at the top end of the rubber mixing bin 1, and the output end of the motor 12 is fixedly connected to the top end of the rotating shaft 2. By installing the motor 12, it is convenient to provide power support for the rotating shaft 2.

[0028] Please refer to Figure 1 , a plurality of support columns 13 are fixedly installed around the bottom end of the rubber mixing bin 1. By installing the support columns 13, it is convenient to support the device.

[0030] In summary, when the rubber mixing device for producing automotive seals is in use, the colloidal raw material is discharged into the interior of the rubber mixing chamber 1 through the feed door 8, and the motor 12 is started. This motor is a well-known device in the art that can be directly purchased on the market. Here, we only use it and do not make improvements to its structure and function. Therefore, we will not elaborate on it in detail here. And the motor is provided with a matching control switch, and the installation position of the control switch is selected according to actual practical needs to facilitate operation and control by the operator. The power is output from the bottom end of the motor 12 to synchronously drive the rotating shaft 2 to perform high-speed rotation operations. While the rotating shaft 2 rotates at high speed, the stirring plate 5 adjusts its angle under the limitation of the guard plate 3 and the connecting shaft 4. Through the continuous angle adjustment of the stirring plate 5, the rubber in different depths inside the rubber mixing chamber 1 is stirred. The guide plate 7 at the top of the stirring plate 5 contacts the rubber, so that the rubber in the top area of the stirring plate 5 is continuously stirred longitudinally. The limiting plate 6 limits the rotation angle of the stirring plate 5. Since the rubber mixing chamber 1 is inverted conical, after heating the rubber in the rubber mixing chamber 1, the rubber can be discharged from the interior of the rubber mixing chamber 1 through the discharge door 9
