Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0019] Embodiment 1: As Figures 1-3 shown, the present utility model provides a mixing and heating device for silicone manufacturing, including a chassis 1. A bottom plate 2 is provided at the upper end of the chassis 1. A mixing barrel 3 is fixedly provided at the upper end of the bottom plate 2. A barrel cover 4 is fixedly provided at the upper end of the mixing barrel 3. Two feeding pipes 41 are fixedly provided at the upper end of the barrel cover 4. A motor 6 is fixedly provided in the middle of the upper end of the barrel cover 4. The output end of the motor 6 penetrates through the barrel cover 4 and is fixedly provided with a disc 61. Four arc-shaped plates 62 distributed in a ring are fixedly provided at the lower end of the disc 61. Five connecting columns 63 are fixedly provided at the outer end of the arc-shaped plate 62. The same-side ends of the five corresponding connecting columns 63 are jointly fixedly provided with a scraper 64. The outer end of the scraper 64 is in movable contact with the inner wall of the mixing barrel 3. A connecting plate 65 is fixedly provided on the lower side of the inner end of the scraper 64. Two mixing columns 66 are fixedly provided at the upper end of the connecting plate 65. The chassis 1 serves as a support structure. Silicone raw materials are added into the mixing barrel 3 through the two feeding pipes 41 at the upper end of the barrel cover 4. The motor 6 is started. The output end of the motor 6 drives the disc 61 to rotate. The four arc-shaped plates 62 distributed in a ring at the lower end of the disc 61 rotate accordingly. The scraper 64 connected by the connecting columns 63 at the outer end of the arc-shaped plate 62 stirs and mixes the falling raw materials at the same time. Since the outer end of the scraper 64 is in movable contact with the inner wall of the mixing barrel 3, it will scrape along the barrel wall during rotation, preventing the raw materials from adhering to the barrel wall and scraping the raw materials near the barrel wall to the mixing area. The two mixing columns 66 on the connecting plate 65 at the lower side of the inner end of the scraper 64 will further stir and mix the silicone raw materials in the mixing barrel 3, so that different raw materials can be fully mixed evenly.

[0020] A heating element 7 is fixedly provided at the upper end of the bottom plate 2, and a heating column 71 is located between the four arc-shaped plates 62. A heating column 71 is fixedly provided at the upper end of the heating element 7. Five heating rings 72 are fixedly provided on the outer surface of the heating column 71, and the five heating rings 72 are evenly spaced up and down. When the heating element 7 at the upper end of the bottom plate 2 is working, the heating column 71 at the upper end of the heating element 7 starts to heat up, and the five heating rings 72 evenly spaced up and down on the outer surface of the heating column 71 heat the silica gel raw material in the mixing barrel 3. Since the heating column 71 is located between the four arc-shaped plates 62, while the arc-shaped plates 62 rotate and stir, the heating rings 72 can heat the raw materials more evenly, promote the chemical reaction between the silica gel raw materials or make them reach the desired physical state, and adopt the heating form from the inside to the outside, cooperate with the peripheral stirring structure, so that the mixing and heating effect of the silica gel raw materials is better.

[0021] Four connecting blocks 8 are fixedly provided on the outer surface of the barrel cover 4 and the upper side of the outer surface of the mixing barrel 3, and the upper and lower corresponding connecting blocks 8 are connected by bolts. The connecting blocks 8 make the barrel cover 4 easy to install and disassemble, and convenient for maintenance.

[0022] Embodiment 2: Figures 1-3 As shown, a groove 21 is provided on one side of the upper end of the chassis 1, a connecting piece 22 is fixedly provided on one side of the outer surface of the bottom plate 2, and the two ends of the connecting piece 22 are rotatably connected to the inner walls of the groove 21 on both sides, and handles 25 are fixedly provided on both sides of the outer surface of the mixing barrel 3. A clamping plate 23 is fixedly provided at one end of the bottom plate 2, and a clamping groove 24 used in conjunction with the clamping plate 23 is provided on one side of the upper end of the chassis 1. When the mixed and heated raw materials need to be taken out, the bottom plate 2 is rotated in the groove 21 by the connecting piece 22, so that the mixing barrel 3 can be tilted, and the handle 25 is pulled to tilt the mixing barrel 3 to facilitate pouring out the raw materials. The clamping plate 23 and the clamping groove 24 cooperate to perform positioning, and the mixing barrel 3 is assisted to return to the placement position. The barrel body structure is easy to tilt, so that the mixed and heated raw materials can be taken out conveniently, thereby improving the convenience of using the device.

[0023] A discharge pipe 5 is provided at one end of the mixing barrel 3, and a baffle 51 is movably inserted at the upper end of the discharge pipe 5. When the silicone raw materials are mixed and heated, the mixing barrel 3 is tilted, and the baffle 51 movably inserted at the upper end of the discharge pipe 5 is pulled out, and the mixed and heated silicone can flow out from the discharge pipe 5, and the discharge is convenient.

[0024] Working principle: the chassis 1 is used as a supporting structure, and the silica gel raw material is added into the mixing barrel 3 through the two feeding pipes 41 at the upper end of the barrel cover 4, and the motor 6 is started. The output end of the motor 6 drives the disc 61 to rotate, and the four arc-shaped plates 62 distributed in a ring at the lower end of the disc 61 rotate accordingly. The outer end of the arc-shaped plate 62 is connected to the scraper 64 through the connecting column 63, and the connecting column 63 stirs and mixes the falling raw materials. Since the outer end of the scraper 64 is in active contact with the inner wall of the mixing barrel 3, it will scrape along the barrel wall during the rotation process to prevent the raw materials from sticking to the barrel wall, and at the same time, the raw materials close to the barrel wall are scraped to the mixing area, and the two mixing columns 66 on the lower connecting plate 65 at the inner end of the scraper 64 will further stir and mix the silica gel raw materials in the mixing barrel 3, so that different raw materials can be fully mixed and evenly mixed;

[0025] The heating element 7 at the upper end of the bottom plate 2 works, and the heating column 71 at the upper end of the heating element 7 starts to heat up. The five heating rings 72 on the outer surface of the heating column 71, which are evenly spaced, heat the silica gel raw materials in the mixing barrel 3. Since the heating column 71 is located between the four arc plates 62, while the arc plates 62 rotate and stir, the heating rings 72 can heat the raw materials more evenly, promote the chemical reaction between the silica gel raw materials or make them reach the desired physical state. The heating form from the inside to the outside is adopted, and the peripheral stirring structure is matched, so that the mixing and heating effect of the silica gel raw materials is better;

[0026] The barrel cover 4 is easy to install and disassemble through the connecting block 8, which is convenient for maintenance;

[0027] When the mixed and heated raw materials need to be taken out, the bottom plate 2 rotates in the groove 21 through the connection piece 22, so that the mixing barrel 3 can be tilted, and the handle 25 is pulled to tilt the mixing barrel 3 so that the raw materials can be poured out conveniently. The positioning is carried out through the cooperation of the clamping plate 23 and the clamping groove 24, and the mixing barrel 3 is assisted to return to the placement position. The barrel structure is easy to tilt, so that the mixed and heated raw materials can be taken out conveniently, thereby improving the convenience of use of the device;

[0028] When the silica gel raw materials are mixed and heated, the mixing barrel 3 is tilted, and the baffle 51 movably inserted at the upper end of the discharge pipe 5 is pulled out, and the mixed and heated silica gel can flow out from the discharge pipe 5, and the discharge is convenient.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
