Abstract
The invention discloses a branch pulverizer pressure feed roller. The pressure feed roller is in a cylindrical structure, and 16 acute-angle grooves are uniformly arranged on the outer circumferential surface along the axial direction at intervals. By changing the structure of the prior art that the outer circumference is provided with projections or gears, the outer circumferential surface is provided with the 16 acute-angle grooves, so that branches can be better conveyed according to the rotation of the pressure feed roller, and the branches are unlikely to break; when the branches are transported, the thrusting force can be applied onto the messy branches for multiple times under the effect of the acute-angle grooves, so that the distribution direction of each branch is similarly identical, the speed and the direction of the branches entering the pulverizer can be enabled to be generally in consistency, and the pulverizer is prevented from being damaged.
Description
Technical field
The present invention relates to branch disintegrating apparatus technical field, particularly relate to a kind of branch crushing machine mip rolls.
Background technology
High efficiency branch crushing machine is a kind of common rod-like articles processing unit (plant), is widely used among branch pulverizing, rod-like articles processing and environment-friendly engineering.But because material structure is complicated, therefore, whether can accurately feeding, become a key link of branch crushing machine.
The mip rolls of traditional feed system be cylinder-like structure, tubular outer rim directly contacts with branch, transmits branch enter pulverizer by the rotation of mip rolls.If the excircle of mip rolls is smooth, its laser propagation effect is poor; Due to the different and crisscross arrangement of branch thickness, in order to increase the laser propagation effect of the tubular outer rim of branch and mip rolls, commercially available mip rolls is provided with multiple projection or gear at its tubular outer fringe surface, as shown in Figure 1, to increase the efficiency of transmission of branch and mip rolls; Its weak point is: the first, when branch is transmitted under the drive of projection, is easily squeezed, can produces a large amount of wood chips, particle and dust after rupturing, and causes branch feeding work bad environments; The second, branch is onwards transmission under the drive of projection, if discharging opening there occurs blocking, branch then can continue positive feed under convex role, thus causing blocking more serious, operating personnel just must stop the rotation of mip rolls, adopt the mode of manual sorting to remove blocking;
3rd, branch, under the extruding of projection and the effect of forced transport, cannot alleviate the situation that branch distributes in a jumble, angle when making branch enter pulverizer, speed are had nothing in common with each other, have impact on crushing effect, Long-Time Service, the random branch of feedstock direction can cause damage to pulverizer.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and provide a kind of branch laser propagation effect good, and the branch crushing machine mip rolls of branch distribution arrangement can be revised.
The technical scheme adopted for realizing object of the present invention is: a kind of branch crushing machine mip rolls, it is characterized in that mip rolls is cylinder-like structure, and the axially uniform intervals of its external peripheral surface is provided with 16 acute groove.
Preferably, described acute groove and an excircle linkage section be adjacent, both are 22 ° 30 ' around the span sum α in the center of circle.
Further, described acute groove is 11 °-12 ° in the span of external peripheral surface around its center of circle of described mip rolls.
Further, described acute groove is 11 ° of 21 ' 18 〞 at the external peripheral surface of described mip rolls around the span α 1 in its center of circle; Excircle linkage section between adjacent two acute groove is 11 ° of 8 ' 42 〞 around the span α 2 in the center of circle.
Preferably, described excircle linkage section extends around the center of circle of described mip rolls radial section, connects the joint face of the end of described excircle linkage section and the acute angle end of described acute groove before extending, and forms the angle of 7 ° with the joint face after extension.
Compared with prior art, operation principle of the present invention and beneficial effect are: change in prior art and circumferentially arrange projection or gear outside, the present invention arranges 16 acute groove at external peripheral surface, and branch is better carried according to the rotation of mip rolls, and not frangibility branch; While conveying branch, mixed and disorderly branch, under the priority effect of multiple acute groove, can be carried out the thrust applied repeatedly, make the distribution arrangement of its branch be tending towards identical by branch, thus speed when ensureing that branch enters pulverizer is roughly the same with direction, can not cause damage to pulverizer.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment:
Be the structure chart of branch crushing machine feed system conveying roller as shown in Figure 2,3, comprise multiple mip rolls 11.
As shown in fig. 3 to 7, mip rolls 11 is cylinder-like structure, and the axially uniform intervals of its external peripheral surface is provided with 16 acute groove 111; Acute groove 111 can promote branch and carry to its rotation direction when mip rolls 11 rotates.
Shown in Fig. 6, described acute groove 111 and an excircle linkage section be adjacent, both are 22 ° 30 ' around the span sum α in the center of circle.That is, the combination circumferentially continuous distributed 16 of above-mentioned acute groove 111 and an excircle linkage section be adjacent, just constitutes the circular radial cross section of mip rolls 11, is 360 °.
Further, described acute groove 111 is 11 °-12 ° in the span of external peripheral surface around its center of circle of described mip rolls 11.
Obtaining best technical scheme through long-term test is: described acute groove 111 is 11 ° of 21 ' 18 〞 at the external peripheral surface of described mip rolls 11 around the span α 1 in its center of circle; Excircle linkage section between adjacent two acute groove is 11 ° of 8 ' 42 〞 around the span α 2 in the center of circle.
Wherein, described excircle linkage section extends around the center of circle of described mip rolls 11 radial section, connects the joint face of the end of described excircle linkage section and the acute angle end of described acute groove 111 before extending, and forming angle β with the joint face after extension is 7 °.M line shown in Fig. 7 is the direction that before extending, acute groove 111 promotes branch conveying; N line is the direction that after expression in the eyes, acute groove 111 promotes branch conveying, and the angle of m and n is 7 °.The throughput direction of branch becomes after n from m, and its throughput direction n can be decomposed into two component: along the power of excircle tangential direction and the power towards direction, the center of circle; Through a large amount of testing and verifications, the effect like this after adjustment is that branch is more easily carried under the acting in conjunction of two component, and can not blocked, extruding, and is easier to revise branch distribution arrangement.
To sum up, 16 acute groove are set at the external peripheral surface of mip rolls 11, branch is better carried according to the rotation of mip rolls, and not frangibility branch; While conveying branch, mixed and disorderly branch, under the priority effect of multiple acute groove, can be carried out the thrust applied repeatedly, make the distribution arrangement of its branch be tending towards identical by branch, thus speed when ensureing that branch enters pulverizer is roughly the same with direction, can not cause damage to pulverizer.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
