In bell mouth shape, which is more than that reference circle and flank are tangent, and the peak of opposite side is no more than phase
At the tooth root of adjacent tooth, to ensure the intensity of tooth, as shown in Figure 3.In order to extend gear life, can be also equipped in hole 5 is granulated
Replaceable wear-resistant sleeve, when wear-resistant sleeve abrasion to a certain extent, can be replaced.Raw material is through driving gear 2 and driven gear 3
Pure rolling enters after squeezing in the granulation hole 5 on driving gear 2 and driven gear 3 and from driving gear 2 and driven gear 3 at random
Centre bore fall into material receiving mechanism；The angle β is between 5-45 °.Pony press 4 is mounted in hopper 1, so as to set
Fixed pressure transferring raw material between meshed gears.Pony press 4 is adjustable from the distance between pitch wheel, so as to reality
When adjust feeding precompression.
Details are as follows：
As shown in Figure 1.A kind of bicyclic mould roller briquetting machine of external tooth, it mainly includes：Hopper 1, gear train assembly（It does not mark
Go out）, precompressed roller arrangement 4, outer tooth ring mold part（Driving gear 2 and driven gear 3）, discharge port（It does not mark）, body（It does not mark
Go out）Deng.
As shown in Figure 2.One external gear wheel engages, tooth force direction（Involute normal direction N1N2）With the direction of motion（Two
The vertical direction of gear centre line）Between angle be known as pressure angle.As can be seen from Figure 2：（1）Same flank profil it is different
Pressure angle in meshing point is different；（2）Normal pressure direction line and path of contact suffered by the gear teeth are all the one of two involute basic circles
On internal common tangent.
As shown in Figure 3.It is analyzed according to 2 strength of gear of prior figures it is found that being molded die hole（Material hole 5 is made, similarly hereinafter）Axis and
The material forming direction of motion should be as consistent as possible with tooth force direction, that is to say, that is molded the axis and material forming of die hole
Angle between the direction of motion and tooth force direction is the smaller the better, i.e. β angles in Fig. 3 are the bigger the better.
It is molded the direction position of die hole（Including β angles）It can specifically determine in accordance with the following methods, such as shown in Figure 3.Cross tooth
Slot line of symmetry（Face）Make a parallel lines（Face）L1, two parallel lines（Face）The distance between diameter according to forming hole, module
It is determined with structure.It is rotatably adjustable as the center of circle using point A that L1 and reference circle meet at point A, line L1, at this time line（Face）L1 and the gear teeth

Gear rotates, and driven gear is intermeshed with driving gear by the gear on its excircle, can not only realize active and passive ring
The negative direction rotation of mould, moreover it is possible at the same ensure the gear teeth in active and passive ring moulds to material seize into, transmit and squeeze.
When biomass bulk material is fallen on through feed inlet on driving gear, since feed arrangement bottom is equipped with pony press 4, because
This is under the action of the linear velocity difference of the rotation of driving gear and pony press and driving gear, loose biomass material
It is seized into and by preliminary consolidation；Enter in engagement process in a pair of of gear teeth, meshing point is in driving wheel root portion and the driven gear teeth
During top, by band（It seizes）The material entered is mainly gradually pressed into molding of the driving gear close to root and guides taper hole and shaping mould
Hole.When meshing point is gradually moved to or during more than reference circle position, material be gradually pressed into the passive gear teeth close to root into
Type guides taper hole and molding die hole.In addition molding die hole axis direction it is close to tooth force direction, be more advantageous to material to
Forming hole（It is granulated hole 5）Conveying and extrusion forming；With the engagement and separation of the gear teeth, gear is granulated material in hole will be through
Cross filling, squeeze and 3 processes of guarantor's type, by this constantly recycle, loose biomass material finally in hole is granulated in layer
Compact formed is the particle with certain density and length.The scraper being fixed on body can then be cut off in time is granulated hole
The molding materials of extrusion, shaped granule are discharged from bicyclic mould discharge end through discharge port, complete pelletization.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
It is same as the prior art or the prior art can be used realized that the utility model is not directed to part.
