[0003] In the production process, the raw material mixing device is one of the most important equipment. The traditional raw material mixing device usually includes a mixing box and a stirring mechanism. The various raw materials that have been pre-melted into liquid are quantitatively added to the mixing box, and then stirred by the stirring mechanism to make the components evenly mixed. After the mixing is completed, the material is poured out for storage or use.
[0004] However, such a raw material mixing device has a low degree of automation, and the quantitative weighing of raw materials, the input and output of materials all require manual operation, which is cumbersome, time-consuming, labor-intensive, and has low work efficiency. Summary of the invention
[0005] The utility model aims to solve the above problems in the prior art and provide a raw material mixing device for knife-scraping cloth production with high automation and high working efficiency.
[0006] The purpose of the utility model can be achieved through the following technical solutions:
[0007] A raw material mixing device for knife-scraped cloth production comprises a frame, a mixing box, a conveying pipe and a raw material barrel, characterized in that the mixing box is connected to the frame, the lower outer side of the mixing box has a protruding connecting plate, the connecting plate abuts against the upper surface of the frame, the mixing box is connected to a stirring mechanism, the stirring mechanism extends into the mixing box, the mixing box has a discharge port at the bottom, a valve is provided on the discharge port, the mixing box has a feed port on the side, one end of the conveying pipe is connected to the feed port and the other end of the conveying pipe is connected to the raw material barrel, and a rotor pump is provided in the middle of the conveying pipe.
[0008] The raw material mixing device for knife-scraped cloth production is used to input liquid raw materials into a mixing box for mixing. The frame supports the mixing box so that there is a gap between the bottom of the mixing box and the ground, which is convenient for the material body in the mixing box to be discharged from the discharge port; the connection between the mixing box and the frame is stable through the structure of the connecting plate to ensure the operation stability of the mixing box; the raw material barrel is connected to the mixing box through a conveying pipe, and the raw material in the raw material barrel is pumped into the mixing box through the conveying pipe by a rotor pump, thereby improving the problem of traditional manual addition of raw materials to the mixing box, with a high degree of automation, saving manpower and high work efficiency. The rotor pump is a prior art and is not described in detail here; the raw materials input into the mixing box are stirred by a stirring mechanism to be fully mixed to obtain a material body with uniform components, and then the valve is opened to discharge the mixed material body from the discharge port.
[0009] In the above-mentioned raw material mixing device for knife-scraped cloth production, the raw material barrel has a hollow interior and an opening at the top, and a roller is provided at the bottom of the raw material barrel.
[0010] The rollers at the bottom of the raw material barrel make it easy to move the raw material barrel and connect it to the conveying pipe, which saves manpower and improves work efficiency.
[0011] In the above-mentioned raw material mixing device for knife-scraped cloth production, the conveying pipe includes a first pipe section and a second pipe section, one end of the first pipe section is connected to the mixing box and the other end of the first pipe section is connected to the output end of the rotor pump, one end of the second pipe section extends into the raw material barrel and the other end of the second pipe section is connected to the input end of the rotor pump.

[0018] Several stirring blades can work simultaneously to fully stir the raw materials in the mixing barrel so that they can be mixed evenly.
[0019] In the above-mentioned raw material mixing device for knife-scraped cloth production, the outer ends of the plurality of stirring blades are adjacent to the inner side wall of the mixing box.
[0020] This structure ensures that the length of the stirring blades at different positions is smaller than the inner wall of the mixing box at the corresponding position. The stirring blades do not contact the mixing box when rotating, ensuring the normal operation of the stirring blades. At the same time, the stirring blades can stir the material at various locations in the mixing barrel, further making the material mixed evenly.
[0021] In the above-mentioned raw material mixing device for knife-scraped cloth production, a weighing device is also included, and the weighing device is arranged between the frame and the mixing box.
[0022] The setting of the weighing device is convenient for real-time weighing of the weight change of the mixing box, and for quantitative monitoring of a variety of raw materials, which reduces the trouble of manually weighing the raw materials before adding them to the mixing box and improves work efficiency.
[0023] In the above-mentioned raw material mixing device for knife-scraped cloth production, the weighing device includes a weighing sensor and a display screen. The weighing sensor is arranged between the connecting plate and the frame. The display screen is connected to the side of the frame and can be electrically connected to the weighing sensor.
[0024] The weighing sensor is used to sense the weight change of the mixing box in real time, and then transmit and display the data on the display screen, making it easy for staff to read the data.
[0025] Compared with the prior art, the raw material mixing device for scraper cloth production has a high degree of automation, is easy to operate, saves manpower, and has high work efficiency.
