Description

Technical Field

[0001] The utility model relates to the field of rubber processing equipment, in particular to a rubber mixing machine for producing rubber tubes. Background Art

[0002] In the production process of rubber tubes, a rubber mixer is needed to mix natural rubber, synthetic rubber and other auxiliary materials to prepare a rubber mix that meets the needs of rubber tube production. Through the mixing of the rubber mixer, a rubber mix with specific properties and viscosity can be prepared to meet the needs of rubber tube production. Rubber processing includes plasticizing, mixing, molding and vulcanization. Rubber mixing is to make rubber products adapt to various use conditions and obtain various properties. In order to improve the performance of rubber products and reduce costs, different compounding agents must be added to the raw rubber. Mixing is a process of mixing the plasticized raw rubber with the compounding agent, placing it in a rubber mixer, and using machinery to completely and evenly disperse the compounding agent in the raw rubber. A rubber mixer is needed in the rubber mixing process.

[0003] The rubber mixing machine includes two rollers rotating inward in opposite directions. The two rollers are generally the same size and rotate relative to each other at different speeds. The raw rubber or rubber compound is drawn into the gap between the two rollers as the rollers rotate. The raw rubber or rubber compound is subjected to strong shearing to achieve the purpose of plasticizing, heat refining or mixing. However, it is inconvenient to adjust the spacing between the rollers in the existing rubber mixing machine. In addition, during production, some raw rubbers, such as chloroprene rubber, acrylic rubber and polyether rubber, have high viscosity, which increases the friction with the roller surface, causing the rubber compound to easily adhere to the rollers and easily stick to the rollers during the mixing process. The adhered rubber compound may deteriorate the fluidity of the subsequent rubber compound, resulting in problems such as blockage and uneven distribution during the processing process. The rubber compound adhered to the roller has a negative impact on the processing of the subsequent rubber compound.

[0004] Therefore, it is necessary to provide a new rubber tube production rubber mixing machine to solve the above-mentioned technical problems. Utility Model Content

[0023] In the specific implementation process, Figure 1-Figure 4As shown, a rubber mixing machine for rubber tube production includes a machine body 1, on which two rollers 4 are arranged, and one side of the machine body 1 is provided with a driving mechanism 3 for driving the two rollers 4 to rotate relative to each other inwards. The driving mechanism 3 is common knowledge for those skilled in the art and will not be described in detail here. Two connecting pieces are respectively arranged at opposite ends of the two rollers 4, and the upper ends of the two connecting pieces arranged on one side of the two rollers 4 are connected to a movable mechanism, and the upper ends of the two connecting pieces arranged on the other side of the two rollers 4 are also connected to a movable mechanism. The two driving mechanisms 3 Used to drive the two rollers 4 to make relative motion, the bottom sides of the two rollers 4 are both provided with scraping plates 5 for scraping the rubber compound on the rollers 4, the two ends of the scraping plates 5 are respectively fixedly connected to the bottom sides of two connecting members arranged oppositely at the two ends of the rollers 4, the connecting members include a rotating drum 6, a fixed plate 7 and a movable block 8, the inner side wall of the rotating drum 6 is movably sleeved on the outer side wall of one end of the roller 4, the outer side wall of the rotating drum 6 is fixedly connected to the fixed plate 7, the upper end of the fixed plate 7 is fixedly connected to the movable block 8, and the movable block 8 is transmission-connected to the movable mechanism;

[0024] The movable mechanism includes a driving motor 9 and a threaded rod 10. The bottom sides of two movable blocks 8 arranged at the same end of the two rollers 4 are slidably arranged in a movable groove opened at the upper end of the body 1. The two movable blocks 8 are respectively threadedly matched with the thread lines with opposite thread directions at both ends opened on the threaded rod 10. One end of the threaded rod 10 is rotatably connected to the side wall of one end of the movable groove, and the other end of the threaded rod 10 is fixed to the output end of the driving motor 9. One side of the driving motor 9 is fixedly connected to the side wall inside the body 1.

[0025] A protective frame 11 is provided outside the machine body 1, and a guide plate 12 is fixedly provided on the upper end of the protective frame 11. The bottom of the guide plate 12 is connected to the top of the protective frame 11. The opening diameter of the vertical section of the guide plate 12 decreases linearly, which can effectively guide the rubber material to fall from the wider part of the guide plate 12 to the narrower part, so that the rubber material falls into the protective frame 11, and ensures that the rubber material can smoothly enter between the two relatively rotating rollers 4. As the rollers 4 rotate, the rubber material is rolled into the gap between the two rollers for mixing processing, so that the various components in the rubber are fully integrated;

[0027] The working principle provided by the utility model is as follows:

[0028] 1. When rubber is being refined, the spacing of the rollers 4 can be adjusted according to the characteristics of the rubber compound.

Different raw rubbers or rubber compounds have different viscosities and fluidities. By adjusting the spacing of the rollers 4, it can be ensured that the rubber compound is subjected to appropriate shear force between the rollers 4 to meet the requirements of plasticizing, hot refining or mixing of different rubber compounds.

[0029] 2. A scraper plate 5 is provided under each of the two rollers 4 to scrape off the rubber material adhering to the rollers 4, thereby preventing the rubber material from sticking to the rollers during processing, and preventing subsequent rubber material from being blocked or unevenly distributed during processing, thereby ensuring product quality to a certain extent.

[0030] 3. After the rubber refining is completed, the rubber falls to the bottom side of the machine body 1. At this time, the rotating motor 2 is started, and the rotating motor 2 drives the two rotating screws 14 to rotate, thereby driving the collecting plate 13 to move and push out the rubber that falls on the bottom side of the machine body 1. At this time, the rubber is collected manually, which is convenient for re-refining the rubber or transporting it to the next processing step, which reduces the workload of manual material collection to a certain extent and improves work efficiency.
