[0002] When producing modified fibers, it is necessary to weigh, measure, and mix the chips and masterbatches according to a predetermined formula. The accuracy of quantitative feeding and mixing affects the quality of the modified fibers to a certain extent.
[0003] At present, the most widely used in production is the loss-in-weight weighing and metering batching machine. However, during the feeding process of the current loss-in-weight weighing and metering batching machine, the ingredients are seriously adsorbed on the inner wall of the hopper due to friction static electricity, which affects the feeding accuracy of the batching machine and causes deviations in the feeding ratio of slices and masterbatches, resulting in color difference of silk cakes during subsequent spinning, reducing product quality and increasing production energy consumption; and when the ingredients are lowered, they are adsorbed on the flap of the feeder due to excessive static friction, resulting in poor closure of the flap, resulting in intermittent feeding during the lowering process of the ingredients; the common batching machine hopper is usually a cylindrical structure with an anti-static coating on the inner wall, which needs to be disassembled and maintained regularly, increasing maintenance costs, and therefore needs to be improved. Utility Model Content
[0004] The utility model provides a batching device for producing modified fibers, which is easy to process and manufacture, can greatly improve the quality of finished products, reduce manual workload, and is not easy to adsorb ingredients on the inner wall of the hopper and the flap of the batching machine, thereby reducing maintenance work and costs, avoiding waste of raw materials, ensuring working stability, and reducing production costs. The utility model solves the technical problems in the prior art that ingredients of the current batching machine are easily adsorbed on the inner wall when working, affecting the feeding accuracy of the batching machine, and are also easily adsorbed on the flap of the batching machine when the ingredients are lowered, resulting in poor closure of the flap, intermittent feeding of ingredients during the lowering process, affecting the quality of the finished products, and poor working efficiency and stability.
[0005] The above technical problems of the utility model are solved by the following technical solutions: a batching device for producing modified fibers, comprising a weighing bracket, a batching hopper is mounted on the weighing bracket, the diameter of the batching hopper gradually decreases from top to bottom, a material control flap for controlling the discharge of materials is provided at the outlet below the batching hopper, a cylinder connected to the material control flap is provided below the weighing bracket, an air inlet pipe and an air outlet pipe are provided on the cylinder, an air inlet pipe is provided at the air inlet pipe and extends to the top of the material control flap, and a plurality of air holes are provided on the air blow pipe for blowing air toward the surface of the material control flap. During operation, the whole is controlled by the system. During operation, the material control flap rotates and opens, and the material falls from the top of the material hopper to the outlet below for weighing. The end of the air inlet pipe is connected to the air pump, and a part of the compressed air is diverted to the air inlet pipe connected to the cylinder, and the material control flap is opened for weighing the ingredients; the other part of the compressed air is diverted to the air blowing pipe to sweep and blow the material control flap; when the material control flap is opened to release the material, the air holes blow on its surface, which can effectively prevent the ingredients from being adsorbed on the surface of the material control flap, avoid the flap from being closed tightly and causing leakage, greatly improve the product quality rate, reduce production energy consumption, and improve economic benefits.
[0006] Preferably, the air inlet pipe is provided with a three-way air pipe, the top and right ends of the three-way air pipe are respectively connected to the air blowing pipe and the air inlet pipe. The air blowing pipe and the air inlet pipe are connected through the three-way air pipe, and the left end of the three-way air pipe is used to connect to the air pump to input compressed air.
[0007] Preferably, a solenoid valve is provided at the end of the three-way air pipe, which controls the air intake at the end of the three-way air pipe, thereby controlling the operation of the air cylinder, the material control flap and the air blowing pipe.
[0008] Preferably, the number of air holes on the air blowing pipe is between 10 and 15. The number of air holes on the air blowing pipe can be adjusted according to actual conditions. The utility model is described by taking 12 air holes on the air blowing pipe as an example.
[0009] Preferably, the blowing direction of the air hole on the blowing pipe and the included angle of the material control flap are 45 degrees. The blowing direction of the air hole on the blowing pipe and the included angle of the material control flap when it is opened are 45 degrees, which can prevent the material from sticking to the material control flap and does not affect the weighing effect and the closing effect.
[0010] Preferably, the diameter of the pores is between 0.5 and 1 mm. The diameter of the pores can be adjusted according to demand, thereby adjusting the blowing volume of the pores in the blowing pipe, while ensuring that normal material falling is not affected. The utility model is described by taking the pore diameter of 1 mm as an example.
[0011] Preferably, the batching hopper is a conical structure with a diameter that gradually decreases from top to bottom, and the inner wall of the batching hopper is a polished mirror surface. The material falls from the top of the batching hopper to the outlet below. Since the inner wall of the batching hopper is inclined and smooth, the static electricity effect caused by the friction between the ingredients and the hopper wall can be reduced, thereby reducing the adsorption of ingredients on the inner wall of the hopper. This design can reduce the amount of sticky materials from 5%-7% to 0%-1%.

[0020] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0021] Example:
[0022] like Figure 1 and 2 As shown in 3, 4, 5 and 6, a batching device for producing modified fibers includes a mounted weighing bracket 1, on which a batching hopper 2 is mounted, the batching hopper 2 is a conical structure with a diameter gradually decreasing from top to bottom, and the inner wall of the batching hopper 2 is a polished smooth mirror surface.
[0023] A material control flap 3 for controlling the material discharge is rotatably installed at the bottom outlet of the batching hopper 2, and a cylinder 4 connected and matched with the material control flap 3 is installed below the weighing bracket 1.
[0024] The side wall of the cylinder 4 is sequentially installed with an air inlet pipe 5 and an air outlet pipe 6 from top to bottom. A three-way air pipe 7 is installed at the end of the air inlet pipe 5. The left end of the three-way air pipe 7 is connected to the air pump device. The left end of the three-way air pipe 7 is also installed with a solenoid valve.
[0025] The right end of the three-way air pipe 7 is connected to the air inlet pipe 5. A blowing pipe 8 is installed at the top of the three-way air pipe 7. The blowing pipe 8 extends to above the material control flap 3, and 12 air holes 9 are opened on the blowing pipe 8. The diameter of the air hole 9 is 1 mm, and the blowing direction of the air holes 9 on the blowing pipe 8 and the material control flap 3 are at an angle of 45 degrees.
[0026] During operation, a load-bearing plate is placed under the batching port, and the end of the three-way air pipe 7 is connected to the nitrogen pump. The whole is controlled by the system. First, the batching of the main and auxiliary materials is set on the control panel, and a signal is sent to the material level sensor for weighing and metering.
[0027] The control panel sends a command to the solenoid valve to transmit the compressed air in the air pump to the air inlet pipe 5, and a part of the compressed air is diverted to the air inlet pipe 5 connected to the cylinder 4 through the three-way air pipe 7, and the material control flap 3 is opened to weigh the ingredients; the other part of the compressed air is diverted to the blowing pipe 8 to sweep and blow the material control flap 3. When the material control flap 3 is opened to release the material, the air hole 9 blows on its surface, which can effectively prevent the ingredients from being adsorbed on the surface of the material control flap 3, avoid the flap being not closed tightly, causing material leakage, greatly improve the product quality rate, reduce production energy consumption, and improve economic benefits.
[0028] After the above instructions are executed, the pressure is released by controlling the air cylinder 4, and the closing instruction is executed to close the material control flap 3, thereby accurately completing the entire batching process.
[0029] The material falls from the top of the batching hopper 2 to the outlet at the bottom. Since the inner wall of the batching hopper 2 is inclined and smooth, the static electricity effect caused by the friction between the material and the hopper wall can be reduced, thereby reducing the adsorption of the material on the inner wall of the hopper. This design can reduce the amount of sticky material from 5%-7% to 0%-1%.
