Abstract
The utility model discloses a twin screw feeder which comprises a transmission motor(8), a box body(5), a hopper(1) and a spiral rod(3). The hopper is arranged above the box body, the rotary shaft(10) of the transmission motor is connected with the spiral rod. The utility model is characterized in that the spiral rod is two rods that are arranged parallel with each other. A bridge gear(7) is arranged between the two spiral rods and the rotary shaft of the transmission motor. The transmission gears(6) of the two spiral rods mesh with the bridge gear at the same time. The bridge gear meshes with the output gear(9) on the rotary shaft of the transmission motor. The utility model adopts twin screw, which reduces half of the cross section of the spiral rod. The utility model improves the precision in the process of manufacture, increases the precision of feeding and lowers unnecessary loss.
Description
Technical field
The utility model relates to a kind of improvement invention of screw feeder.
Background technology
Product is single screw feeder mostly in the market, and material, is exported by screw rod uniform distribution material again through screw rod through hopper.Producer for guarantee its reinforced error can be controlled at ± 5%, generally adopt dual mode: the one, improve the working accuracy of screw rod, keep the pitch of screw rod identical; The 2nd, guarantee that screw rod has constant revolution.But these two kinds of methods can't make reinforced error drop to minimum, because in the middle of the same material, its density is uneven, as powder is arranged in the particle, and have thick in the powder and thin branch, tend to exceed standard by the reinforced error of single screw feeder in this case, thereby can cause unnecessary loss to producer.
The utility model content
In view of the existing technical matters of known technology, to be solved in the utility modelly provide a kind of a kind of twin screw feeder that improves charging precision.In order to achieve the above object, the utility model is finished by following mode: this kind twin screw feeder, have driving motor, casing, hopper, spiral material bar, described hopper places the top of casing, the rotating shaft of described driving motor and spiral material bar are in transmission connection, it is characterized in that described spiral material bar is two and is set up in parallel, be provided with carrier gear between the rotating shaft of described two spiral material bars and driving motor, the transmission gear of described two spiral material bars simultaneously and the carrier gear engagement, described carrier gear is meshed with output gear in the driving motor rotating shaft.
Driving motor starts, and drives the carrier gear running, and carrier gear makes double helix material bar rotate in the same way.Material is through hopper, and blanking is to double helix material bar, and material is exported in the uniform rotation of double helix material bar.
Added material is difficult for causing bridging in hopper phenomenon in order to make, described hopper is provided with vibration electromagnet and material baffle.
The utility model adopts double helix material bar, makes that the cross-sectional plane of spiral material bar is little one times, makes that precision has improved in the machine manufacture process, move simultaneously owing to two spiral material bars simultaneously, make reinforced amount complementation, reduced reinforced error, strengthened reinforced precision.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is an integral structure scheme drawing of the present utility model;
Fig. 2 removes schematic top plan view behind the hopper for the utility model;
Fig. 3 is the cutaway view of the utility model A-A.
The specific embodiment
Accompanying drawing is represented integral structure of the present utility model and embodiment, further describes the relevant details of embodiment below in conjunction with accompanying drawing.This kind feeder has driving motor 8, casing 5, hopper 1, carrier gear 7, two spiral material bars 3 that are set up in parallel, described hopper 1 places the top of casing 5, the transmission gear 6 of described two spiral material bars 3 simultaneously and carrier gear 7 engagements, described carrier gear 7 is meshed with output gear 9 in the driving motor rotating shaft 10.
Start driving motor 8, the output gear 9 of driving motor 8 clockwise rotates, and drives carrier gear 7 and rotates counterclockwise, because the transmission gear 6 of two spiral material bars 3 is meshed with carrier gear 7 simultaneously, makes 3 while of double helix material bar clockwise direction rotate.Material is put into hopper 1, described hopper 1 is provided with vibration electromagnet 2 and material baffle 11, and material makes material the bridging phenomenon can not occur in hopper 1 under 2 vibrations of vibration electromagnet and move downward thus, 11 pairs of materials of material baffle play shunting action, guarantee the material dosing conveying.Described material is to spiral material bar 3, and spiral material bar 3 rotates, and material moves to delivery port along the screw channel 4 of spiral material bar 3.
Identical in quality and rotating speed spiral material bar 3 of setting spiral material bar 3 is identical, and the diameter cross of simple helix material bar is the twice of the diameter cross of double helix material bar 3, therefore in manufacturing process the precision of double helix material bar 3 than the height of simple helix material bar.
The pitch precision of setting spiral material bar is identical and rotating speed spiral material bar is identical, if the reinforced error of simple helix material bar is 5%, and the reinforced error of a spiral material bar of double helix material bar setting has reached 5%, the reinforced error of another spiral material bar is 0%, and then the true reinforced error of double helix material bar is 2.5%; Infer thus when the reinforced error of another spiral material bar 0%～5% the time, then the reinforced error of double helix material bar is 2.5%～5%, when the reinforced error of another spiral material bar-5%～0% the time, then the reinforced error of double helix material bar is 0%～(-) 2.5%, therefore when simple helix material bar reaches higher limit, double helix material bar is very low through the probability that two spiral material bar errors neutralized, reached after the complementation higher limit, more can not reach lower limit; When in like manner reaching lower limit as if simple helix material bar, the probability that double helix material bar then reaches lower limit is also very low, can not reach higher limit.To reach higher limit more much smaller than simple helix material bar with the probability of lower limit for double helix material bar thus, so the charging precision of double helix material bar has improved several times.
