Description

Technical Field

[0001] The present invention relates to the technical field of ice cube slicing processing, and in particular to a fully automatic ice sawing machine. Background Art

[0002] In ice cube processing, large ice cubes are processed into required shape structures through means such as cutting, for example, cutting a large cubic ice cube into sheet-shaped ice cubes; in traditional ice cube slicing processing, generally, the saw blade is set horizontally or vertically, and then workers push the ice cube to make the ice cube pass through the saw blade for cutting. The workers carry away the sliced ice and move the remaining ice cube back to the original point to push for cutting again; the above production process has low efficiency. When workers push the ice cube, the ice cube is easily driven by the saw blade to shift, resulting in unqualified quality of the sliced ice; when the thickness of ice cutting is controlled by workers, the thickness of the sliced ice cut out is likely to vary greatly; in addition, industrial accidents where workers are cut by the saw blade are also likely to occur.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

For example, it may be a fixed connection, a detachable connection, or an integral one; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the present invention, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0035] Reference Figure 1-10 , there is shown a fully automatic ice sawing machine, including a frame 1, on which a lower fixing mechanism 2 that can move along a first direction is provided. The lower fixing mechanism 2 includes a bearing platform 21 for carrying ice cubes and capable of lifting, and a plurality of lower clamping blocks 22 that can move to clamp the lower part of the ice cubes are provided on the bearing platform 21; a cutting mechanism 4 is provided on the frame 1, and the cutting mechanism 4 includes a horizontally arranged sawing tool 41, and the sawing tool 41 is arranged on the moving path of the lower fixing mechanism 2 to cut the ice cubes.

[0036] In this embodiment, the ice cubes are placed on the bearing platform 21, and the lower part of the ice cubes is fixed by a plurality of lower clamping blocks 22; then the bearing platform 21 is moved to make the ice cubes pass through the cutting mechanism 4; the horizontally arranged sawing tool 41 cuts the ice cubes, and the upper part of the ice cubes is cut into sheet ice, and the cut sheet ice is removed; while the lower part of the ice cubes is still fixed on the lower fixing mechanism 2, the bearing platform 21 moves to the original position and rises by a moving distance to make the upper surface of the ice cubes higher than the sawing tool 41, and then the bearing platform 21 is moved again to make the ice cubes pass through the cutting mechanism 4, and so on to cut the ice cubes multiple times. In the above process, the ice cubes are fixed and moved by the lower fixing mechanism 2, so that the moving process of the ice cubes is stable. The lower part of the ice cubes is fixed by the lower clamping blocks 22 to prevent the sawing tool 41 from driving the ice cubes to shift, and the flatness of the sheet ice is improved; in addition, the thickness of the ice cubes to be cut is determined by the lifting height of the bearing platform 21, which can avoid large differences in the thickness of the sheet ice; there is no need for workers to push the ice cubes, avoiding the workers being in close contact with the sawing tool 41 and improving safety.

[0037] In some specific embodiments, to improve the stability of the ice block during movement and when being cut, referring to Figure 1-3 , a top fixing mechanism 3 movable along a first direction is further provided on the frame 1. The top fixing mechanism 3 includes a top plate 311 for abutting against the upper surface of the ice block and a plurality of movable upper clamping blocks 32. The plurality of upper clamping blocks 32 are at least distributed on both sides of the ice block to clamp the upper part of the ice block, and the upper clamping blocks 32 are located below the top plate 311. Briefly speaking, the ice block is supported by the bearing platform 21, and the upper surface of the ice block abuts against the top plate 311, which can prevent the ice block from moving in the vertical direction and prevent the ice block from vibrating longitudinally during cutting and disengaging from the lower fixing mechanism 2. In addition, by clamping the lower part and the upper part of the ice block with the lower clamping blocks 22 and the upper clamping blocks 32 respectively, the ice block can be prevented from shifting in the horizontal direction.

[0038] In this embodiment, the ice block is placed on the bearing platform 21, and the lower part of the ice block is fixed by a plurality of lower clamping blocks 22. Then, the bearing platform 21 is raised so that the upper surface of the ice block abuts against the top plate 311, and the upper clamping blocks 32 fix the upper part of the ice block. Then, the lower fixing mechanism 2 and the upper fixing mechanism 3 move synchronously, and the ice block passes through the cutting mechanism 4. Referring to Figure 3 , the sawing tool 41 is located between the lower fixing mechanism 2 and the upper fixing mechanism 3. When the ice block completely passes through the cutting mechanism 4, the upper part and the lower part of the ice block are separated. The upper part is the sliced ice cut out, and the sliced ice is clamped by the upper fixing mechanism 3, while the lower part of the ice block remains fixed on the lower fixing mechanism 2. At this time, the lower fixing mechanism 2 moves to the origin, and the upper fixing mechanism 3 can move the sliced ice to the discharging place for discharging. For example, a conveyor belt (not shown) is butted at the tail end of the frame 1, and the upper fixing mechanism 3 places the sliced ice on the conveyor belt and conveys it away. Then, the upper fixing mechanism 3 moves to the origin, and the bearing platform 21 is raised so that the upper surface of the ice block abuts against the top plate 311, and the processing is cycled in this way. In addition, the upper fixing mechanism 3 and the lower fixing mechanism 2 respectively take away the upper part and the lower part of the ice block, which can prevent the upper part and the lower part of the ice block from freezing and adhering again.

[0039] Specifically for the above solution, to facilitate the movement of the upper fixing mechanism 3, referring to Figure 2 and Figure 8, the upper fixing mechanism 3 includes a first moving platform 31 that can move along a first direction. The top plate 311 is fixed to the bottom of the first moving platform 31, and a first driver 321 for driving the upper clamping block 32 to move is provided on the top plate 311. A first screw rod (not shown) arranged along the first direction, a first guide rail (not shown) arranged parallel to the first screw rod, and a second driver 33 for driving the first screw rod to rotate are provided on the frame 1. The first moving platform 31 is threadedly connected to the first screw rod and slidably connected to the first guide rail. Briefly speaking, the second driver 33 drives the screw rod to rotate, and under the limitation of the first guide rail, the first moving platform 31 moves along the axial direction of the screw rod, that is, along the first direction. The second driver 33 can be a motor.

[0040] Additionally preferably, referring to Figure 9 , the first driver 321 is arranged between the top plate 311 and the first moving platform 31. The first driver 321 is drivingly connected to a first connecting plate 322. The first connecting plate 322 and the upper clamping block 32 are connected by a first vertical plate 323. The first vertical plate 323 is located on the outer peripheral side of the top plate 311, and the top plate 311 is located between the first connecting plate 322 and the upper clamping block 32. In this way, placing the first driver 321 between the top plate 311 and the first moving platform 31 can prevent ice cubes from colliding with the first driver 321. The first driver 321 can be a cylinder. Among them, referring to Figure 8 , taking the first direction as a reference, a plurality of upper clamping blocks 32 are symmetrically distributed on both sides of the top plate 311. The upper clamping block 32 can move along a second direction, and the second direction is perpendicular to the first direction in the horizontal plane. Intercepting rods 34 are fixedly arranged on the upper clamping blocks 32 at the two sides of the top plate 311 that are farthest from the cutting mechanism 4. The intercepting rods 34 are used to abut against the end face of the ice cube away from the cutting mechanism 4. In this way, when the ice cube is cut by the sawing tool 41, the sawing tool 41 will generate a thrust along the first direction on the ice cube. The intercepting rods 34 can make the moving process of the ice cube more stable and prevent relative displacement in the first direction between the ice cube and the top plate 311.

[0041] Specifically for the above solution, to facilitate the lifting of the bearing platform 21, referring to Figure 4 and Figure 5 , the lower fixing mechanism 2 includes a second moving platform 23 that can move along the first direction. The bearing platform 21 is liftably arranged on the second moving platform 23. A third driver 231 for driving the bearing platform 21 to lift is provided on the second moving platform 23. A fourth driver 221 for driving the lower clamping block 22 to move is provided on the bearing platform 21. Additionally, to facilitate the movement of the second moving platform 23, referring to Figure 5, a second screw rod 25 arranged in a first direction, a second guide rail 26 arranged in parallel with the second screw rod 25, and a fifth driver 27 for driving the second screw rod 25 to rotate are provided on the frame 1; the second moving table 23 is threadedly connected to the second screw rod 25 and slidably connected to the second guide rail 26. The moving principle of the second moving table 23 is the same as that of the first moving table 31, and the fifth driver 27 can be a motor.

[0042] In addition, to prevent the ice cubes from colliding with the fourth driver 221, refer to Figure 4 , Figure 5 and Figure 6 , a support plate 211 is fixedly arranged on the bearing platform 21, the fourth driver 221 is arranged between the bearing platform 21 and the support plate 211, the fourth driver 221 is drivingly connected with a second connecting plate 222, the second connecting plate 222 and the lower clamping block 22 are connected through a second vertical plate 223, the second vertical plate 223 is located on the outer peripheral side of the support plate 211, and the support plate 211 is located between the second connecting plate 222 and the lower clamping block 22. Among them, the fourth driver 221 can be a cylinder.

[0043] Specifically in the above solution, the lower clamping blocks 22 can be arranged on the four sides of the support plate 211 to respectively clamp the four outer side surfaces of the ice cubes; and further preferably, for facilitating the placement of the ice cubes on the support plate 211, refer to Figure 4 , Figure 5 and Figure 7 , taking the first direction as a reference, a plurality of lower clamping blocks 22 are symmetrically distributed on both sides of the support plate 211; the lower clamping blocks 22 can move along a second direction; stoppers 24 that can be lifted and lowered by a sixth driver 241 are provided at both ends of the bearing platform 21, the sixth driver 241 is fixed to a third connecting plate 243, and the third connecting plate 243 is driven by a seventh driver 242 to move along the first direction; a plurality of lower clamping blocks 22 respectively abut against the left and right side surfaces of the ice cube along the first direction, and the two stoppers 24 respectively abut against the front and rear end surfaces of the ice cube along the first direction. Among them, the stoppers 24 can be lifted to be higher than the support plate 211 or lowered below the support plate 211. In this way, when it is necessary to place the ice cube on the support plate 211, due to the large weight of the ice cube, the ice cube can be placed at one end of the support plate 211 and pushed to slide to the center of the support plate 211, and then the stoppers 24 are lifted so that the two stoppers 24 respectively abut against the front and rear end surfaces of the ice cube along the first direction. Among them, the frame 1 can be docked with a conveyor belt (not shown), and the ice cube is conveyed to the support plate 211 by the conveyor belt to achieve further automation.

[0044] Specifically in the above solution, refer to Figure 3 andFigure 10 , the sawing tool 41 is a band saw blade; the cutting mechanism 4 includes a bracket 42, a driving wheel 43 provided on the bracket 42, a driven wheel 44 provided on the bracket 42, and an eighth driver 45 for driving the driving wheel 43 to rotate; the band saw blade is in transmission connection with the driving wheel 43 and the driven wheel 44. Among them, the band saw blade is wound around the driving wheel 43 and the driven wheel 44. When the eighth driver 45 drives the driving wheel 43 to rotate, the driving wheel 43 and the driven wheel 44 drive the band saw blade to rotate, so as to cut the passing ice cubes.

[0045] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
