The embodiment provides an application scenario: the cutting mechanism 2 includes two cutting main rollers which extend in the horizontal direction, are arranged side by side, and are arranged at intervals. The two ends of the cutting main roller are respectively arranged at the front end of the cutting frame 6 through bearing boxes. One end of the cutting main roller is connected with a driving motor, the driving motor drives the cutting main roller to rotate, and the driving motor is arranged at the rear end of the cutting frame 6. The cutting wire is wound in from one end of a cutting main roller and is wound out from the other end. For example: the cutting line winds in from above one end of the main cutting roller and winds out from above the other end of the main cutting roller.
The top of the cutting frame 6 is also provided with a feeding mechanism 4 which drives the silicon rod to move downwards and move between the two main cutting rollers, and the silicon rod is sliced through a cutting line.
As shown in fig. 4 to 6, the two take-up and pay-off mechanisms are arranged on the same side of the cutting mechanism 1, and as shown in the view angle of fig. 1, the two take-up and pay-off mechanisms are arranged on the left side of the cutting mechanism or on the right side of the cutting mechanism. The cutting wire released from one of the take-up and pay-off rollers 31 is wound into the cutting mechanism through the tension pulley 21, the cutting wire wound out from the cutting mechanism is guided to the other take-up and pay-off roller 31 through the tension pulley 21, and the cutting wire reciprocates between the two take-up and pay-off rollers 31, the tension pulley 21 and the cutting main rollers 11.
In this solution, the axes of the take-up and pay-off rolls 31 in the two take-up and pay-off mechanisms 3 extend horizontally, for example parallel to the axis of the cutting main roll 11, as shown in fig. 5 and 6. Alternatively, the axes of the take-up and pay-off rolls 31 in the two take-up and pay-off mechanisms 3 extend in the vertical direction, as shown in fig. 4.
In addition to the above, the feeding mechanism 4 may be disposed at the bottom of the cutting frame 6 to drive the silicon rod to move upward for slicing.
The number of cutting main rolls in the cutting mechanism 2 may be two, three or more than three. If the number of the cutting main rollers is two, the two cutting main rollers are arranged along the horizontal direction; if the number of the cutting main rollers is three, the three cutting main rollers are arranged into a regular triangle; if the number of the cutting main rollers is four, the four cutting main rollers are arranged in a regular triangle or rectangle.
When the number of the cutting main rollers 11 is three, two cutting main rollers 11 are above and one cutting main roller 11 is below. For example: the cutting line may be wound in from one end of the upper one of the cutting main rollers 11 and wound out from the other end of the lower one of the cutting main rollers 11.
The tension mechanism specifically comprises a tension wheel 21, a tension motor and a tension arm, wherein the tension arm is connected with an output shaft of the tension motor, and the tension motor is used for driving the tension arm to swing. The tension pulley 21 is rotatably provided to the tension arm, and the tension pulley 21 guides the cutting line during rotation, and the tension pulley 21 is used for adjusting the tension of the cutting line during swinging together with the tension arm.
The present embodiment also provides another implementation of the tension mechanism: the tension mechanism is a linear tension mechanism, and specifically comprises: a tension wheel and a tension wheel driving mechanism for driving the tension wheel to move in a plane perpendicular to the cutting main roller 11, close to or far from the cutting mechanism to adjust the tension of the cutting line.
One embodiment is: as shown in fig. 2, the tension pulley 21 moves in the vertical direction (Y direction in fig. 2) toward or away from the cutter main roller 11. Specifically, the tension pulley 21 is higher than the cutting main roller 11, and the cutting line passes around the upper half of the tension pulley 21. When the tension of the cutting line is small, the tension wheel 21 is driven to move upwards, so that the cutting line is tightened to increase the tension; when the string tension is high, the tension pulley 21 is driven downward, causing the string to loosen slightly and reduce the tension.
Another embodiment: as shown in fig. 3, the tension pulley 21 moves in the horizontal direction, approaching or moving away from the cutter main roller 11. When the tension of the cutting line is small, the tension wheel 21 is driven to move rightwards, so that the cutting line is tightened to increase the tension; when the string tension is high, the tension pulley 21 is driven to move to the left, causing the string to loosen a little bit to reduce the tension.
The calculation principle of the linear tension mechanism is as follows:
force balance equation at tension pulley on linear tension mechanismWherein f=f 1 ＝F 2 。
Tension of linear tension mechanism
Speed difference v of linear tension mechanism line ＝v 1 -v 2 。
Acceleration in a linear tension mechanism
The linear motor provides constant thrust output and influences factors of tension fluctuation in the linear tension mechanismIs the difference between the mass of the motion mechanism and the speed (or linear acceleration) of the two sides of the tension wheel.
Compared with a tension mechanism adopting a swing arm structure, the linear displacement error generated by the swing angle does not exist in the linear motion of the linear tension mechanism. Assuming that the cutting lines on the two sides of the tension wheel are equal in length and the two ends are fixed, the displacement of the cutting lines on the two sides is affected equally by the movement displacement of the linear tension mechanism when the tension is adjusted, namely delta l 1 ＝Δl 2 。
Compared with a tension mechanism adopting a swing arm structure, the linear motion of the linear tension mechanism has no influence of a swing angle.
Compared with a tension mechanism adopting a swing arm structure, when the speed difference of the linear tension mechanism on two sides of the tension wheel is constant, the main influencing factor index of the tension fluctuation is thatThe error is smaller.
The parameters in the above formulas are as follows:
F、F 1 and F 2 -cutting line tension, unit N;
F T -linear motor thrust, unit N;
m 1 -mass of linear motor, unit kg;
v 1 ,v 2 -linear speed of the cutting line on both sides of the tension wheel, in m/min;
F f the friction force of the linear motor is very small and can be ignored, and the unit is N;
v line -the movement speed of the linear motor in m/min;
on the basis of the above technical solution, an electric control area may be formed at the bottom of the cutting frame 6, and at least one of the electric control device, the liquid supply cylinder in the cooling system, and the hydraulic driving device may be disposed in the electric control area. If the electric control device is arranged in the electric control area at the bottom, the problem that the electric control device is arranged in the cutting area in the traditional scheme can cause larger interference to the rotation operation of the cutting main roller can be solved, the electromechanical separation is realized, the water and electric safety is improved, the electric control device can better isolate dust generated by cutting, and the service life of the electric control device is prolonged.
If the liquid supply cylinder or the hydraulic driving device is arranged in the electric control area at the bottom, the distance between the liquid supply cylinder or the hydraulic driving device and the cutting mechanism 2 can be shortened, the length of the liquid supply pipeline and the length of the hydraulic pipeline can be shortened, on one hand, the manufacturing and maintenance cost can be reduced, on the other hand, the control hysteresis rate can be reduced, the control accuracy can be improved, the cutting quality can be improved, the liquid supply path can be shortened, and the leakage and the cooling heat loss can be reduced.
According to the scheme, the bottom space of the cutting frame 6 is utilized, an electric control device, a liquid supply cylinder, a hydraulic driving device and the like can be arranged, the space utilization rate is improved, the volume of the slicer is further reduced, and the slicing machine is convenient to hoist and transport.
After the improvement of the scheme, the whole volume of the slicer is reduced, the weight is reduced, a hub can be additionally arranged at the bottom of the cutting frame 6, and the position of the cutting line can be moved through the hub. The whole volume of the slicer is reduced, the occupied area is small after the weight is lightened, more slicers can be accommodated in unit space, and the production efficiency is improved.
