as shown in fig. 10, the junctions of two sides of the reinforcement member 77 are vertically and upwardly extended and provided with fence plates 78, folding doors 79 are arranged between the front ends and the rear ends of the two sets of fence plates 78, the folding doors 79, the fence plates 78, the folding doors 79 and the fence plates 78 are sequentially connected end to form a fence with a closed loop structure, the closed loop structure penetrates up and down, and the folding doors 79 can fold and drive the two sets of fence plates 78 to be close to each other and can not influence the extraction of the reinforcement member 77 from between the formed ice cubes 710 and the inner side walls of the strip-shaped grooves 72;
since the ice powder is extruded into the ice cubes 710, the ice powder before extrusion is larger than the volume of the formed ice cubes 710, and thus the rail with the closed loop structure extends upwards outside the edge of the strip-shaped groove 72 to provide a space for temporarily storing the ice powder; therefore, a user can pour a certain amount of ice powder into the inner cavity of the strip-shaped groove 72, and at the moment, the fence with the closed loop structure limits the ice powder overflowing the inner cavity of the strip-shaped groove 72. Because the profile modeling cable 7 is in a circular structure, the device shown in fig. 7 can rotate outside the profile modeling cable 7, so that two groups of reinforcing members 77 and the rail with the closed loop structure can relatively enter between two rows of guide wheels 94, and the two rows of guide wheels 94 can relatively move and rotate along the length track direction of the profile modeling cable 7 to avoid the reinforcing members and the rail with the closed loop structure.

the cross section of the bar-shaped groove 72 along the length track direction of the profiling cable 7 is approximately in a trapezoid structure, and the opening of the bar-shaped groove 72 of the trapezoid structure is relatively narrow, so that ice cubes 710 can be prevented from being separated from the bar-shaped groove 72. As shown in fig. 8, an arc chute 911 is formed in the upper seat 91, the telescopic device 96 is mounted on an arc slider 961, and the arc slider 961 slides arcuately relative to the upper seat 91 under the guidance of the arc chute 911; the upper seat 91 is also provided with a traversing assembly 98, the traversing assembly 98 can adopt a screw rod transmission structure driven by a manual drive/motor, the upper seat 91 is also horizontally and slidably connected with a moving seat 981, the traversing assembly 98 drives the moving seat 981 to horizontally and linearly slide on the upper seat 91, the moving seat 981 is vertically extended and provided with a vertical chute, one side of the arc-shaped sliding block 961 is provided with a cylinder with a circular structure, and the cylinder vertically moves and rotates in the vertical chute; so that horizontal movement of traversing assembly 98 causes arcuate slide 961 to slide arcuately in arcuate chute 911.
When the arc-shaped slide block 961 is positioned at the middle position of the arc-shaped slide groove 911, the telescopic device 96 drives the pressing plate 97 to vertically lift so as to squeeze the ice powder in the strip-shaped groove 72, and dead angles exist at the left side and the right side of the strip-shaped groove 72 with the trapezoid structure at the moment, so that the ice powder cannot be directly squeezed; at this time, when the arc slider 961 moves to the left limit position of the arc chute 911, the telescopic device 96 drives the lifting direction of the pressing plate 97 to be just parallel to the right side edge of the bar-shaped groove 72 of the trapezoid structure; when the arc-shaped slide block 961 moves to the right limit position of the arc-shaped slide groove 911, the telescopic device 96 drives the lifting direction of the pressing plate 97 to be just parallel to the left side edge of the strip-shaped groove 72 of the trapezoid structure. Thereby realizing the extrusion and blocking of the ice powder in the strip-shaped groove 72 with the trapezoid structure.
It should be noted that, when the telescopic device 96 drives the pressing plate 97 to lift and squeeze the ice powder, in order to improve stability, the adjusting assembly 95 drives the upper seat 91 and the lower seat 92 to approach each other at a relatively close distance to clamp and fix the profiling cable 7. Slightly adjusting the spacing between the upper seat 91 and the lower seat 92 allows the rotatable guide wheel 94 to move or rotate on the profile cable 7.
Example six: all of the contents of embodiment five are included:
because the foot is treaded on the upper surface of the ice cubes 710, the upper surface of the ice cubes 710 is scratched or dimpled, so that the friction force is increased, and the simulation experiment effect is reduced.

when the scraper 973 is not used, the scraper 973 is completely retracted into the pressing plate 97, at this time, the lower edge of the scraper 973 is flush with the bottom of the pressing plate 97, so that the extrusion work of the pressing plate 97 is prevented from being influenced, and the bottom shape of the scraper 973 is matched with the bottom shape of the pressing plate 97; when the ice cube scraping machine is required to be used, the profiling cable 7 is oppositely arranged between the upper guide wheels 94 and the lower guide wheels 94, the pressing plate 97 is attached to the upper surface of the ice cube 710 to be operated/the outer surface of the profiling cable 7, then the adjusting screw 971 is rotated to drive the mounting seat 972 to descend, the scraper 973 moves to the lower side of the pressing plate 97 along with the descending cutter point, the cutter point of the scraper 973 is inserted into the ice cube 710 for a small distance, and then the two guide wheels 94 roll on the profiling cable 7 relatively, so that the scraper 973 is driven to move along with the upper surface of the ice cube 710 to scrape a scraped layer/a layer with a small pit.
The movement of the platen 97 facilitates scraping the ice pieces 710 to the same shape as the exterior surface of the profiled cable 7.
Embodiment seven: all of example six is included:
the difference is that the scraper 973 is replaced with a friction block, and the movement of the friction block is used for polishing the upper surface of the ice cubes 710, which is beneficial to polishing the upper surface of the ice cubes 710. As shown in fig. 10, when the ice powder is pressed into ice blocks 710, the telescopic device 96 drives the pressing plate 97 to move above the fence plate 78 and the folding door 79, and at this time, the pressing plate 97 does not interfere with the fence plate 78 and the folding door 79 when the guide wheel 94 rolls on the profiling cable 7; then the friction block is driven to move downwards to be abutted against the upper surface of the ice block 710 for polishing, at the moment, the friction block is limited in the fence of the closed loop structure formed by the fence plate 78 and the folding door 79, the safety limiting function is achieved, and damage to the strip-shaped groove 72 of the profiling cable 7 in the moving process of the friction block is avoided.
Similarly, damage to the bar slot 72 of the profile cable 7 by movement of the scraper 973 is avoided.
Example eight: all of examples six or seven are included:
after the ice cubes 710 are extruded, they may be cryogenically shaped for a period of time by external refrigeration equipment; when the ice cubes 710 are severely scraped, the ice surface can be melted by means of sprinkling, heating and the like, uneven places on the ice surface are filled with water, and the ice surface is restored to a complete and smooth state after being frozen at low temperature.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present invention.
