Problems solved by technology
[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the existing dust-free feeding device generally generates negative pressure suction with the help of a negative pressure fan, so as to filter the dust in the raw material particles during the feeding process, The feeding method is usually to install a solenoid valve under the material storage device, and control the feeding amount and feeding speed by controlling the opening degree of the solenoid valve. The raw material particles are directly dropped and fed through the solenoid valve, so that the dust can not be filtered to the maximum. The speed of the raw material particles passing through the solenoid valve is not only related to its own gravity, but also related to the pressure of the upper raw material and the resistance between the raw materials, so it is impossible to achieve fast feeding, and it is not easy to accurately control the feeding speed and feeding amount

The invention discloses a dust-free feeding device for the production of polyethylene plastic packaging bags. A feeding tube is fixedly connected to a side wall of the material blocking cover away from the support plate, a material storage cylinder is arranged in the feeding blocking cover, and a material storage tank is arranged in the material storage cylinder. The present invention uses centrifugal force to throw out the raw material particles to complete the feeding. Since the feeding speed is related to the centrifugal acceleration of the raw material particles, it is only necessary to control the rotational speed of the first driving motor, and then the feeding speed can be adjusted as required. Combined with the first driving The working time of the motor can control the feeding amount, and the error is small, and the control of feeding speed and feeding amount is precise. The control of the feeding amount is more precise.
Description
technical field [0001] The invention relates to the technical field of polyethylene plastic production, in particular to a dust-free feeding device for the production of polyethylene plastic packaging bags. Background technique [0002] Polyethylene plastic packaging bag is a kind of packaging bag made of polyethylene plastic as raw material, which is produced and processed through a series of processes of batching, plasticizing film blowing, printing, slitting and bag making. In the batching stage, in order to avoid raw material particles The dust is mixed in it, which affects the quality of the produced plastic packaging bags. Generally, the feeding and batching of raw material particles is carried out by means of a dust-free feeding device. [0003] The existing dust-free feeding device generally uses a negative pressure fan to generate negative pressure suction, so as to filter the dust in the raw material particles during the feeding process. The feeding method is usual...
