Description

Technical Field

[0001] This utility model relates to the field of mixing, and more specifically, it relates to a raw material mixing device for the production of knife-coated cloth. Background Technology

[0002] Knife-coated fabric is a composite material produced using a specific manufacturing process, primarily used in advertising printing, construction hoardings, awnings, and other fields. Its name derives from a coating technique used in the production process—the "knife-coating method"—which involves using a scraper to evenly coat liquid PVC onto a base fabric to form a waterproof layer.

[0003] The production process of knife-coated fabric requires mixing of coating materials, which necessitates the use of mixing equipment. Since the coating of knife-coated fabric utilizes PVC resin, plasticizers, stabilizers, fillers, pigments, and other functional additives, these materials exist in various forms, including granules, powders, and liquids. These different forms of materials vary in quality, and after being poured into the mixing equipment, they tend to pile up and separate into layers. Most existing mixing equipment only uses rotating stirring rods or paddles in fixed positions to mix the materials, making it difficult to evenly mix the separated materials, requiring considerable time and thus reducing production efficiency.

[0004] Based on the above, the purpose of this utility model is to provide a raw material mixing device for the production of knife-coated cloth, so as to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a raw material mixing device for the production of coated fabric. This invention involves setting a rotating premixing tank inside the main body of the container, and then installing a stirring rod inside the premixing tank. Multiple raw materials are premixed through the premixing tank and the stirring rod. During this process, the raw materials are evenly sprinkled into the lower part of the inner cavity of the container through the perforation. The stirrer mixes and stirs these raw materials, while the scraper scoops up large particles of raw materials that have sunk to the bottom and sends them to the middle and upper part of the raw material pile, further preventing the raw materials from accumulating and settling at the bottom, thereby improving the mixing efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a raw material mixing device for the production of knife-coated cloth, comprising a barrel body, a rotating shaft rotatably connected to the barrel body, a stirrer fixedly connected to the rotating shaft, an inlet pipe, an outlet pipe and a drive mechanism for driving the rotating shaft to rotate on the barrel body, a premixing barrel rotatably connected inside the barrel body, a plurality of leakage holes provided on the lower end surface of the premixing barrel, a stirring rod fixedly connected to the part of the rotating shaft located inside the premixing barrel, a driven mechanism for driving the premixing barrel to rotate inside the barrel body, the rotation directions of the premixing barrel and the rotating shaft being opposite, a scraper fixedly connected to the lower end of the stirrer, the scraper being arc-shaped and having a plurality of filter holes provided on the scraper.

[0007] By adopting the above technical solution, when raw material mixing is required, multiple raw materials are poured into the barrel through the feed inlet. The raw materials will first accumulate in the premixing barrel and then fall downwards through the drain hole. During this process, the drive mechanism and the driven mechanism drive the rotating shaft and the premixing barrel to rotate respectively. During this process, the rotating shaft will drive the stirring rod and the agitator to rotate respectively. The stirring rod will premix the raw materials in the premixing barrel that have not yet fallen. As the premixing barrel rotates, the raw materials in the premixing barrel will fall more evenly to the lower end of the barrel's inner cavity, preventing the same raw materials from piling up together. The agitator mixes and stirs the falling raw materials. During the mixing process of the agitator, the scraper will scoop up the raw materials at the bottom. The smaller diameter raw materials will pass through the filter holes, while the larger diameter raw materials will slide along the inclined surface of the scraper to the upper middle part of the raw materials, further preventing the raw materials from piling up and separating, thus making the mixing efficiency higher.

[0008] The present invention is further configured such that: the driven mechanism includes a drive gear fixedly connected to the rotating shaft, a connecting gear meshing with the drive gear is rotatably connected to the inner wall of the barrel, and a toothed ring meshing with the connecting gear is fixedly connected to the premixing barrel.

[0009] The present invention is further configured such that: a stirring rod and a scraper are fixedly connected to the portion of the rotating shaft located inside the premixing tank, and the scraper abuts against the inner wall of the premixing tank.

[0010] The present invention is further configured such that: the driving mechanism includes a motor, and the output shaft of the motor is fixedly connected to the rotating shaft.

[0011] In summary, this utility model has the following beneficial effects:

[0012] This invention features a rotating premixing tank inside the main body of the container, with a stirring rod inside the premixing tank. Multiple raw materials are premixed using the premixing tank and stirring rod. During this process, the raw materials are evenly sprinkled into the lower part of the container's inner cavity through the perforation. The stirrer mixes these raw materials, while the scraper scoops up large particles of raw materials that have sunk to the bottom and moves them to the upper middle part of the raw material pile, further preventing the raw materials from accumulating and settling at the bottom, thereby improving mixing efficiency.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] Raw material mixing device for knife-coated cloth production, such as Figures 1-2 As shown, the device includes a barrel body 1, a rotating shaft 2 rotatably connected to the barrel body 1, a stirrer 3 fixedly connected to the rotating shaft 2, a feed pipe 4, a discharge pipe 5, and a drive mechanism for rotating the rotating shaft 2 are also installed on the barrel body. Multiple feed ports can be provided. A premixing barrel 6 is rotatably connected inside the barrel body 1. Several leakage holes are opened on the lower end face of the premixing barrel 6. A stirring rod 11 is fixedly connected to the part of the rotating shaft 2 located inside the premixing barrel 6. A driven mechanism for rotating the premixing barrel 6 is provided inside the barrel body 1. The rotation directions of the premixing barrel 6 and the rotating shaft 2 are opposite. A scraper 7 is fixedly connected to the lower end of the stirrer 3. The scraper 7 is arc-shaped and has several filter holes. The diameter of the filter holes can be controlled to allow powder and small particles to pass through while preventing large particles from passing through.

[0022] Furthermore, the driven mechanism includes a drive gear 8 fixedly connected to the rotating shaft 2, a connecting gear 9 rotatably connected to the inner wall of the barrel 1 and meshing with the drive gear 8, a gear ring 10 fixedly connected to the premixing barrel 6 and meshing with the connecting gear 9, and a plurality of connecting rods 13 respectively fixedly connected to the gear ring and the premixing barrel.

[0023] Furthermore, a stirring rod 11 and a scraper 12 are fixedly connected to the portion of the rotating shaft 2 located inside the premixing tank 6, with the scraper 12 abutting against the inner wall of the premixing tank 6.

[0024] Furthermore, the drive mechanism includes a motor 14, the output shaft of which is fixedly connected to the rotating shaft 2.

[0025] Working principle: When raw materials need to be mixed, multiple raw materials are poured into the barrel 1 through the feed inlet. Most of the raw materials will first accumulate in the premixing barrel 6 and fall downwards through the drain hole. During this process, the motor drives the rotating shaft 2 to rotate, which in turn drives the drive gear 8, stirring rod 11, stirrer 3, and scraper 12 to rotate. The drive gear 8 drives the gear ring 10 to rotate through the connecting gear 9, which in turn drives the premixing barrel 6 to rotate in the opposite direction to the rotating shaft 2 through the connecting rod. During this process, the stirring rod 11 will stir the raw materials in the premixing barrel 6 that have not yet fallen into the barrel. During the premixing process, the scraper removes the raw materials clogging the surface of the drain hole. As the premixing tank 6 rotates, the raw materials inside the premixing tank 6 are more evenly distributed to the lower end of the inner cavity of the tank body 1, preventing the same raw materials from piling up together. The agitator 3 mixes and stirs the falling raw materials. During the mixing process of the agitator 3, the scraper 7 scoops up the raw materials at the bottom. The smaller diameter raw materials pass through the filter holes, while the larger diameter raw materials slide along the inclined surface of the scraper 7 to the middle and upper part of the raw materials, further preventing the raw materials from piling up and separating, thus making the mixing efficiency higher.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
