The advantage & improvement of screw feeder

Screw feeder is safe and convenient, and mobile, such as the use of more than one spices of the same material, just a feeding machine can also be used for more than mixing spices on the material, eliminating the trouble of manual feeding, feeding work Become more secure, more time-saving, more effort.
JT screw feeder is a necessary auxiliary machine for plastic processing machinery. It can transfer the plastic raw material of powder or granule to the hopper directly and adjust the special equipment of the mixer. Contact material made of stainless steel, the process of transport raw materials completely free from pollution, without bringing any foreign body, enabling the production process to achieve fully enclosed automation.
The main advantages:
screw feeder is widely used, with the continuous expansion of the use of the market demand continues to increase. The equal-pitch helical blade has been unable to meet the actual needs of the production, put forward variable-pitch variable pitch blade cutting processing problems, improper choice of materials, easily lead to unnecessary waste, to this end, made some improvements. In order to achieve full use of materials, improve economic efficiency purposes.
1, The use of variable pitch technology to improve the feeding capacity of the screw feeder. The spiral input section uses a smaller pitch. The middle section pitch increased to 10 ~ 20mm, output pitch pitch increased by 10 ~ 20 mm. So that the input section powder filling volume increases, the middle section and the output section with the pitch larger, less filling, doing so can effectively prevent some of the powder in the transmission back when the card or blocking phenomenon.
2, The screw feeder is generally horizontal or inclined upward conveying mode, the screw axis of the anti-loose mainly by the former bearing completed. The front bearing is equipped with thrust bearing, which is tightened and prevented from loosening by double nut and single-stop washer. In order to enhance the anti-loose effect, in the front nut on both sides of the set screws.
3, The working angle of the screw feeder, according to the general law, the screw machine in the power, pitch, speed, bulk density and filling the same conditions. Productivity decreases with increasing inclination, and it is also a non-linear relationship. Taking into account the overall structure of the equipment and the needs of the spiral machine productivity, the working angle of the screw machine is maintained at 45 or so.
