The mixing chamber is equipped with a stirring device and a driving device to fully mix the silicone sealant inside the mixing chamber. A heating element is provided at the bottom of the mounting frame to keep the silicone sealant inside the mixing chamber in a soft state.

[0004] However, after mixing is completed, the silicone residue on the inner wall of this type of mixing equipment is difficult to clean, which not only affects the quality of the next batch of mixing, but also reduces the service life of the equipment. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that it is difficult to clean the silicone sealant residue on the inner wall of the equipment, which not only affects the quality of the next batch of mixing but also reduces the service life of the equipment.

[0024] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Reference Figures 1-6 A silicone sealant mixing device includes a frame 1, an outer container 2 fixed on the frame 1, a mixing tank 21 fixed inside the outer container 2, a top cover 3 detachably connected to the top of the outer container 2, a stirring rod 4 rotating on the top cover 3 via a rotating shaft, a stirring paddle 5 fixed on the outer surface of the stirring rod 4, and a motor for driving the stirring rod 4 to rotate installed on the top of the top cover 3. A wall scraping assembly for scraping the material on the inner wall of the mixing tank 21 is provided inside the mixing tank 21. The wall scraping assembly includes a scraper 61 provided in the mixing tank 21, and a scraper pad 62 fixed on the side of the scraper 61 near the inner wall of the mixing tank 21.

[0027] Furthermore, the bottom of the mixing tank 21 has a discharge plate 22 that rotates via a rotating shaft, and the mixing tank 21 is connected to a feed pipe 23 that penetrates the outer container 2.

[0028] Furthermore, the wall scraping assembly also includes a slider 63 that slides on the outer surface of the stirring paddle 5. The slider 63 is connected to the scraper 61 via a connecting rod 60. An L-shaped block 64 for adjusting the position of the scraper pad 62 is fixed to the top of the slider 63.

[0029] Furthermore, a fixed rod 65 slides on the L-shaped block 64, and a lifting block 66 is fixed on the outer surface of the fixed rod 65. A fixed hole 67 is provided on the stirring paddle 5. When the fixed rod 65 is inserted into the fixed hole 67, the slider 63 is fixed to the stirring paddle 5. A spring 69 is sleeved on the outer surface of the fixed rod 65, and the two ends of the spring 69 are fixedly connected to the L-shaped block 64 and the lifting block 66 respectively.

[0030] Furthermore, a sliding door 68 is rotatably connected to the top cover 3 via a pivot, and the sliding door 68 is located above the fixing rod 65.

[0031] During the initial installation or adjustment phase of the silicone sealant mixing equipment, the operator first manually adjusts the scraper assembly according to the dimensions of the mixing tank 21. By pulling the lifting block 66, the fixing rod 65 is disengaged from the fixing hole 67 of the agitator 5. At this time, the slider 63 can slide freely on the outer surface of the agitator 5. The operator moves the slider 63 to a suitable position according to the inner diameter of the mixing tank 21, so that the scraper pad 62 on the scraper 61 can fit tightly against the inner wall of the mixing tank 21. After adjusting the position, the lifting block 66 is released, and the fixing rod 65 is reinserted under the action of the spring 69. Insert the slider 63 into the corresponding fixing hole 67 and fix it to the stirring paddle 5 to complete the adjustment of the position of the wall scraping component. During the mixing process, the motor drives the stirring rod 4 to rotate, and the stirring paddle 5 rotates accordingly. The slider 63, connecting rod 60, scraper 61 and scraper pad 62, which are fixedly connected to the stirring paddle 5, rotate synchronously. The scraper pad 62 is in close contact with the inner wall of the mixing tank 21. Due to the elastic deformation ability of its rubber material, even if there is slight deformation or unevenness in the inner wall of the mixing tank 21, the scraper pad 62 can always maintain a good fit and scrape off the silicone material attached to the inner wall of the mixing tank 21.

[0032] It is worth noting that adjustments can be made by opening the sliding door 68.

[0033] The further advantage of the above is that by installing the wall scraper assembly on the stirring mechanism, the material adhering to the inner wall of the mixing tank 21 is scraped off as the stirring mechanism rotates, avoiding material accumulation that affects heat transfer and mixing effect. The scraper pad 62 is made of rubber material, which has a certain elastic deformation capacity and can adapt to the slight deformation of the inner wall of the mixing tank 21, ensuring effective cleaning of the tank wall.

[0034] Based on Example 1, Example 2:

[0035] Reference Figures 1-6 ,

[0036] Furthermore, a heating and cooling system is provided inside the outer container 2. The heating and cooling system includes a heating coil 71 fixed between the outer container 2 and the mixing tank 21, and a cooling coil 72 fixed between the outer container 2 and the mixing tank 21. Both the cooling coil 72 and the heating coil 71 are connected to a liquid inlet pipe 73.

[0037] Furthermore, all inlet pipes 73 extend outside the outer filling body 2, and all inlet pipes 73 are equipped with control valves 74.

[0038] Before the silicone sealant mixing operation begins, the required material mixing temperature range is set in the control system according to the silicone sealant production process requirements. During the mixing process, when the temperature sensor detects that the material temperature in the mixing tank 21 is lower than the lower limit of the set range, the control system automatically opens the control valve 74 corresponding to the heating coil 71. Steam or heat transfer oil enters the heating coil 71 through the inlet pipe 73, and the heating coil 71 heats the material in the mixing tank 21, causing the material temperature to gradually rise. When the temperature sensor detects that the material temperature has reached the upper limit of the set range, the control system shuts off the heating. The control valve 74 of the heating coil 71 is opened, and the control valve 74 of the cooling coil 72 is also opened. Cooling water enters the cooling coil 72 through the liquid inlet pipe 73. The cooling coil 72 absorbs the heat of the material in the mixing tank 21, causing the material temperature to drop. This cycle continues. Through the coordinated work of the heating coil 71 and the cooling coil 72, the temperature of the material in the mixing tank 21 is precisely controlled, keeping it within the set temperature range. This meets the temperature requirements of the silicone sealant during the mixing process, preventing the material from deteriorating or changing its properties due to overheating. It also ensures that the material can be fully and evenly mixed at the appropriate temperature.

[0039] It is worth noting that the temperature sensor and control system can use common models available on the market.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
