Abstract

The utility model 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

A kind of branch crushing machine mip rolls

Technical field

The utility model relates to branch disintegrating apparatus technical field, particularly relates 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 due to material structure complexity, therefore, whether accurately feeding, becomes 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; Because branch thickness is different and crisscross arrangement, in order to increase the laser propagation effect of tubular outer rim of branch and mip rolls, commercially available mip rolls is provided with multiple projections or gear at its tubular outer fringe surface, as shown in Figure 1, and to increase the efficiency of transmission of branch and mip rolls; Its weak point is: the first, when branch is transmitted under protruding drive, be easily squeezed, and after rupturing, can produce a large amount of wood chip, particle and dust, cause branch charging work under bad environment; The second, branch is transmission forward under protruding drive, if obstruction has occurred discharging opening, branch can continue positive feed under protruding role, thereby cause obstruction more serious, operating personnel just must stop the rotation of mip rolls, adopt manual sorting's mode to remove obstruction;

The 3rd, branch, under the effect of protruding extruding and forced transport, cannot be alleviated the mixed and disorderly situation about distributing of branch, angle, speed while making branch enter pulverizer are had nothing in common with each other, affected crushing effect, long-term use, the random branch of feedstock direction can cause damage to pulverizer.

Utility model content

The purpose of this utility model is for the technological deficiency existing in prior art, and provides a kind of branch laser propagation effect good, and can revise the branch crushing machine mip rolls of branch distribution arrangement.

For realizing the technical scheme that the purpose of this utility model adopts, be: a kind of branch crushing machine mip rolls, is characterized in that mip rolls is cylinder-like structure, is evenly arranged at intervals with 16 acute groove in the axial direction of its external peripheral surface.

Preferably, described acute groove and an excircle linkage section being adjacent, both around the span sum α in the center of circle be 22 ° 30 '.

Further, described acute groove is 11 °-12 ° at the external peripheral surface of described mip rolls around the span in its center of circle.

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 extending.

Compared with prior art, operation principle of the present utility model and beneficial effect are: change in prior art projection or gear are set on excircle, the utility model arranges 16 acute groove at external peripheral surface, branch can better be carried according to the rotation of mip rolls, and frangibility branch not; When carrying branch, branch, under the priority effect of multiple acute groove, can apply thrust repeatedly by mixed and disorderly branch, makes the distribution arrangement of its branch be tending towards identical, thereby ensure that speed and direction when branch enters pulverizer are roughly the same, can not cause damage to pulverizer.

The specific embodiment

Below in conjunction with specific embodiment, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

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. 3-7, mip rolls 11 is cylinder-like structure, is evenly arranged at intervals with 16 acute groove 111 in the axial direction of its external peripheral surface; 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 being adjacent, both around the span sum α in the center of circle be 22 ° 30 '.That is to say, the combination of above-mentioned acute groove 111 and an excircle linkage section being adjacent, around 16 of circumference continuous distributed, has just formed the circular radial cross section of mip rolls 11, is 360 °.

Further, described acute groove 111 is 11 °-12 ° at the external peripheral surface of described mip rolls 11 around the span in its center of circle.

Through long-term test, obtaining best technical scheme 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 sections, 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 that before extending, acute groove 111 promotes the direction that branch is carried; N line is that after expression in the eyes, acute groove 111 promotes the direction that branch is carried, and the angle of m and n is 7 °.The throughput direction of branch is after m becomes n, and its throughput direction n can be decomposed into two component: along the power of excircle tangential direction with towards the power of center of circle direction; Through a large amount of testing and verification, the effect after adjusting is like this that branch is more easily carried under the acting in conjunction of two component, and can be not blocked, push, and be easier to revise branch distribution arrangement.

To sum up, at the external peripheral surface of mip rolls 11,16 acute groove are set, branch can better be carried according to the rotation of mip rolls, and frangibility branch not; When carrying branch, branch, under the priority effect of multiple acute groove, can apply thrust repeatedly by mixed and disorderly branch, makes the distribution arrangement of its branch be tending towards identical, thereby ensure that speed and direction when branch enters pulverizer are roughly the same, can not cause damage to pulverizer.

The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
