Technical Field

The invention relates to the field of ice carving processing, in particular to a cutter assembly for cutting ice and snow and a use method thereof.

Background

The ice carving is one artistic form carved with ice as main material and belongs to the field of modeling technology. Like sculptures made of other materials, ice sculptures are also classified into circular sculptures, relief sculptures and open sculptures. Ice engraving presents a number of difficulties due to the variability and volatility of the material, and to carefully select ice suitable for ice engraving, the ideal ice should be made of pure water so that it has a high degree of transparency and yet contain as few bubbles as possible.

The requirements on cutting tools are higher, the cutting device comprises a sawing mechanism, in an ice cutting environment, the air humidity is high, the waterproof capability of the existing sawing mechanism is poor, water easily enters the sawing mechanism to freeze, and even short circuit can be caused; in addition, the existing sawing mechanism is easy to generate heat, and high rotating speed is difficult to maintain, so that the notch of the ice carving is not smooth enough, and the cutting quality is affected.

Publication number CN213147042U discloses a sawing mechanism for ice machine with pipe, comprising a base, a sawing shaft rotatably connected to the base, and a saw blade connected to the sawing shaft; a bearing group is arranged between the sawing shaft and the base; and the sawing shaft is connected with the base through non-contact sealing labyrinth seals above and below the bearing group. The base and the sawing shaft are in non-contact sealing labyrinth sealing connection, so that friction heating between the sawing shaft and the base is avoided as much as possible while the sealing performance is ensured; on one hand, the heating can be reduced to ensure the service life, and the sawing mechanism can maintain high rotating speed; on the other hand, the situation that the pipe ice is polluted by fragments generated by abrasion can be avoided. The above mentioned reference has the following disadvantages:

(1) The prior art of the saw blade milling cutter for ice carving has the problems that the friction between the saw blade and ice cubes is large, the cutter and the cutter bar are easy to deform, and the cutting is difficult.

(2) In the process of cutting ice cubes, the saw blade with different diameters needs to be replaced at any time for carving, and the replacement of the existing saw blade is very inconvenient.

(3) The saw blade is in the in-process of cutting the ice-cube, because the ice-cube is fragile, if there is deviation in the cutting direction in the in-process of cutting, continue deep cutting, can cause the ice-cube to burst for whole ice-cube abandonment leads to preceding carving work white cost.

(4) In the engraving process, a groove with a larger width is needed to be cut sometimes, the existing saw blade can only cut a gap, then multiple multi-angle cutting is adopted, the effect can be achieved, and the efficiency is low.

It is therefore necessary to design a knife assembly for cutting ice and snow in which the blades are less in friction when in contact with the ice, the cutting operation for the ice can be completed at one time without multiple angle cuts, and the blades in the knife assembly can be removed and the knife can automatically protect the blades when in contact with the harder portions of the ice, and the cutting direction with errors can be finely adjusted.

S4: when making ice cubes, because there is gas in water, so there are various bubbles in the ice cubes after shaping, these bubbles cause the density and the hardness of each position in ice cubes to all be different, so when the cutter is to ice cubes cutting, if ice cubes local hardness is too big, when the cutter suffered resistance, protection mechanism 32 is triggered, upper tray 34 and lower tray 37 break away from this moment, upper tray 34 is by second spring 33 counterbalance after breaking away from, lower tray 37 and third spring 40 counterbalance, last upper tray 34 and lower tray 37 are the interlock again, this process ensures that the cutter can cut off the junction in the ice cubes that cutting hardness is too high voluntarily, avoid the cutter to damage the power supply when acting on the high hardness region constantly.

The working principle of the device is as follows: when cutting ice cubes, four detachable blades 1 are combined to form a cross axe structure, a plurality of arc teeth 3 are formed on the detachable blades 1, and the characteristics of the arc teeth 3 are matched with the cross axe structure, so that the detachable blades 1 are intermittently contacted with the ice cubes, and the intervals among the plurality of arc teeth 3 can enable the cut ice cubes to be discharged rapidly, and the processing efficiency is improved. The first spring 6 is sleeved outside the rotating shaft 4, the central ball 7 is sleeved outside the first spring 6, the two buffer shells 8 are symmetrically arranged outside the central ball 7, the connecting portions 9 of the detachable blade 1 and the buffer shells 8 are fixedly connected through bolts, and after the detachable blade 1 is fixedly connected with the buffer shells 8, the two buffer shells 8 are propped against the two ends of the first spring 6. The specific process of the buffer mechanism 5 is as follows: the first spring 6 can provide the variation of cutter in the axis direction of pivot 4, when the cutter assembly cuts the ice-cube and exists the offset along the axis direction of pivot 4, first spring 6 compresses, the error offset between pivot 4 and the center ball 7 can be offset by the compression of first spring 6, simultaneously, the connected mode of two buffer shells 8 and center ball 7 is clearance fit, namely when there is the error in the cutting direction, the ice-cube exerts the effort to removable blade 1, removable blade 1 links firmly with two buffer shells 8, two buffer shells 8 can take place the deformation, because this deformation direction is inhomogeneous, unpredictable, so the clearance volume between center ball 7 and the two buffer shells 8 is the omnidirectional, this clearance volume provides the displacement for the deviation that the cutting direction produced, in conclusion, buffer mechanism 5 can carry out self-adaptation with cutter assembly when the cutting direction produces the error, improve the stability of cutting process.

Before the detachable blade 1 cuts ice cubes, in order to prevent ice cubes from cracking and improve the cutting efficiency, the device needs to preprocess the ice cubes, namely an operator needs to rotate the rotary table 29 to adjust the angle of the rotary cutter 13, and the lifting frame 31 can prevent secondary solidification of ice residues on the rotary table 29 due to low temperature of the working environment of the device, so that the work of the operator is influenced, the anti-skid lines 30 are beneficial to the better operation of the rotary table 29 by the operator, and the slipping caused by icing of the device during the rotation of the rotary table 29 is prevented.
