[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0032] Referring to Figures 1 - 6 , an inclined mixing device for thermoplastic polyester elastomer raw materials, including a base 1, a transmission component 2 is arranged on the back of the base 1, a stirring component 3 is arranged on one side of the transmission component 2, and a tipping component 4 is arranged on the inclined side of the base 1.
[0033] The transmission component 2 includes a groove opened on the back of the base 1. A positioning block 200 is rotatably connected inside the groove through a rotating shaft.

[0034] The stirring component 3 includes a cover body 300 fixedly installed on one side of the positioning block 200. A cover plate 301 is fixedly installed at the bottom of the cover body 300. A motor 302 is fixedly installed on the inner top wall of the cover body 300. The output shaft of the motor 302 is fixedly installed with a rotating rod 304. A receiving cavity is opened on the inclined side of the base 1. A rotating plate 305 is rotatably connected inside the receiving cavity through a rotating shaft. One side of the rotating plate 305 is rotatably connected to a cylinder 306 through a bearing 303. The bottom of the rotating rod 304 penetrates through the cover plate 301 and extends into the inside of the cylinder 306. Stirring blades 307 are fixedly installed on the surface of the rotating rod 304. A motor 308 is fixedly installed at the bottom of the rotating plate 305. The output shaft of the motor 308 penetrates through the rotating plate 305 and is fixedly connected to one side of the cylinder 306;
[0035] In this embodiment, the provided stirring component 3 can drive the raw materials at the lower part of the cylinder 306 to rotate during use, so as to cooperate with the provided scraper 404 to scrape and mix the raw materials during use, thereby keeping the raw materials evenly mixed and improving the mixing uniformity of the device. There is a gap between the cover plate 301 and the cylinder 306, and the bottom of the cross plate 403 is slidably connected to the top of the cylinder 306. The top of the cover plate 301 is communicated with a feed pipe 7. The top of the feed pipe 7 is hinged with a box door 8 through a hinge. A button is fixedly installed on one side of the top of the box door 8. An arc-shaped groove is opened on the surface of the button. The provided feed pipe 7 and box door 8 facilitate adding polyurethane elastomer rubber raw materials into the device during use, and the feeding operation can be carried out without stopping the machine during work. A circular hole for the output shaft of the motor 308 to pass through is opened on the rotating plate 305, and the inner wall of the circular hole is rotatably connected to the surface of the output shaft of the motor 308. The provided circular hole facilitates the normal rotation of the motor 308 during use and avoids interfering with the rotation of the output shaft of the motor 308.
[0036] The pouring assembly 4 includes an electric push rod 400 rotatably mounted on one side of the inner wall of the storage cavity. The top of the electric push rod 400 is rotatably connected to an inclined rod 401 through a shaft seat. One end of the inclined rod 401 is rotatably connected to the bottom of the rotating plate 305 through a shaft seat. One side of the top of the bearing 303 is fixedly installed with a vertical rod 402. One side of the vertical rod 402 is fixedly installed with a horizontal plate 403. One end of the bottom of the horizontal plate 403 is fixedly installed with a scraper 404. One side of the scraper 404 is in contact with one side of the inner wall of the cylinder 306. The inner ring of the bearing 303 is fixedly connected to the surface of the cylinder 306. The bottom of the outer ring of the bearing 303 is fixedly connected to the top of the rotating plate 305. The upper surface of the outer ring of the bearing 303 is fixedly connected to one side of the vertical rod 402, and one side of the vertical rod 402 is not in contact with the surface of the cylinder 306;
[0037] In this embodiment, the provided bearing 303 facilitates the driving of the cylinder 306 to rotate by the motor 308 during use, and is not restricted by the rotating plate 305 during rotation. The top of the horizontal plate 403 is in contact with the lower surface of the cover plate 301, and the axis of the rotating rod 304 is located at one-fourth of the diameter of the cylinder 306. The axis of the provided rotating rod 304 is located at one-fourth of the diameter of the cylinder 306, which can accelerate the mixing of raw materials during use. The provided stirring assembly 3 and pouring assembly 4 facilitate the scraping of the inner wall of the cylinder 306 during pouring, preventing raw materials from sticking to the inner wall of the cylinder 306 during discharging, maintaining clean and thorough discharging, and eliminating the need for staff to clean the inner wall of the cylinder 306;
[0038] Furthermore, the setting of the inclined rod 401 can increase the inclination angle of the cylinder 306 for downward feeding during the extension and pushing of the electric push rod 400, improving the feeding effect.
[0039] Refer to Figure 1 In a preferred embodiment, threaded support rods 5 are threadedly connected to the four corners of the bottom of the base 1. The bottom of the threaded support rods 5 is rotatably connected to a support plate 6 through a shaft seat. The lower surface of the support plate 6 is provided with anti-slip lines. The provided threaded support rods 5 and support plate 6 can adjust the support height of the four corners of the bottom of the device according to the placement position of the device, preventing the four corners of the bottom of the device from being uneven during use.
[0040] Furthermore, the inclination angle of the cylinder 306 is 10° - 30°, and it is uniformly dispersed in cooperation with the rotation speed of the stirring blades 307 of 10 - 30 revolutions per minute. Or, the inclination angle is reduced to 10° - 15° to extend the residence time of the material in the mixing area and improve the uniformity.
[0041] Specifically, the amount of materials stirred by the cylinder 306 should not exceed 60% of the total volume of the cylinder 306 to avoid a large load during inclined stirring, reduce the convective mixing effect during stirring, and prevent material overflow.
[0042] Working principle: When it is necessary to mix raw materials, open the box door 8, add the raw materials to be mixed into the interior of the cylinder 306 through the feed pipe 7, then close the box door 8, and control the motor 302 and the motor 308 to work. The motor 302 drives the stirring blades 307 on the rotating rod 304 to rotate, thereby mixing the raw materials in the cylinder 306. The motor 308 drives the cylinder 306 to rotate in the opposite direction to the motor 302, so that while the stirring blades 307 mix the raw materials, the raw materials in the cylinder 306 can be driven to rotate. At the same time, with the obstruction of the scraping plate 404, the scraping plate 404 blocks and scrapes the raw materials, improving the mixing uniformity of the raw materials. The inclined design of the cylinder 306 allows the materials to slide down along the inclined barrel wall to form a convective cycle, accelerating the mixing speed and making the materials more evenly distributed in the mixing chamber, further reducing the mixing dead angle. When it is necessary to perform the discharging operation, control the hydraulic telescopic rod 202 to shorten. The hydraulic telescopic rod 202 drives the positioning block 200 on the connecting rod 201 to rotate around the rotating shaft, so that the motor 302 and the rotating rod 304 on the cover plate 301 are separated from the cylinder 306, thus avoiding the rotating rod 304 from limiting the cylinder 306. Then control the electric push rod 400 to extend, so that the shaft seat on the electric push rod 400 presses on one side of the rotating plate 305, so that the cylinder 306 on the rotating plate 305 is turned outwards, so that the mouth of the cylinder 306 is inclined downwards. At the same time, control the motor 308 to rotate. When the motor 308 rotates, it drives the cylinder 306 to rotate. At this time, the scraping plate 404 can scrape the raw materials on the inner wall of the cylinder 306, and under the action of gravity, it flows out along the inner wall of the cylinder 306, avoiding sticking to the inner wall of the cylinder 306 during the discharging process.
[0043] As described above, only the preferred specific embodiments of the present invention are provided, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of some structures, devices, and method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
