Description
Technical Field
The invention relates to the technical field of flour processing, and particularly discloses a dust-free packaging machine for flour production.
Background
The basic process of the flour bagging process is that an operator opens the woven bag firstly and then sleeves the woven bag on the flour discharging pipe, the two symmetrical arc-shaped clamping plates are used for clamping the end part of the woven bag on the discharging pipe, and then the discharging pipe is opened to measure the discharged flour through the flow meter. In the process of bagging flour, the space at the lower end of the woven bag is filled with the flour, the air in the woven bag moves upwards, a large amount of dust is easily generated under the scouring action when the flour falls, the dust escapes from the gap at the upper end of the woven bag, so that the whole processing workshop is full of the dust, and the dispersed flour in the air sucked by the operating personnel can influence the physical and mental health of the operating personnel. At present, all the existing flour dust-free packing machines suck flour which moves upwards along with air by introducing a set of negative pressure dust collection system, and discharge the flour after filtration.
For example, the invention of patent No. CN110294150A discloses a semi-automatic dustless quantitative flour packing machine, which comprises a base, a frame, a storage bin and a conveyor belt, wherein the frame is arranged on the upper surface of the base, the lower end of the storage bin is connected with a discharge pipe, the end of the discharge pipe penetrating through the top wall of the frame and entering into the frame is provided with a material valve, the outer side of the discharge pipe below the material valve is provided with a dust absorption ring barrel, and a negative pressure dust absorption cavity is formed between the outer wall of the discharge pipe and the inner wall of the dust absorption ring barrel; the flour packing machine is high in automation degree, the straightening, sealing and conveying functions of the bag opening of the packing bag are realized through the PLC function, and the automation degree is high; in addition, a dust absorption ring cylinder and a dust absorption fan connected with the dust absorption ring cylinder are arranged on the circumferential surface of the discharge pipe, so that dust excited in the discharging process of the discharge pipe can be absorbed and recovered, and the workshop environment is greatly improved; although the semi-automatic flour dust-free quantitative packaging machine disclosed by the invention can adsorb and recover the excited dust in the flour packaging process, two defects exist when the excited dust is adsorbed by a negative pressure dust collection system in the prior art; firstly, an additional set of negative pressure dust collection system is required, so that the structure of the whole packaging machine is more complex, and the long-time operation of the negative pressure dust collection system can increase the electric energy loss; secondly, the negative pressure dust collecting system can not carry out self-regulation according to the speed of unloading in the in-process of carrying out adsorption filtration to the flour, leads to the unable effective dust absorption that will arouse when power is lower, and can also take away the flour of whereabouts in-process when power is higher. Therefore, aiming at the defects of the existing semi-automatic flour dust-free quantitative packaging machine, the design of the dust-free packaging machine for flour production, which does not need to introduce a negative pressure dust collection system and can be adjusted according to the blanking speed, is a technical problem to be solved.
