For scenarios that require fine cleaning, such as precision molds and electronic components, existing equipment is difficult to efficiently convert block dry ice into uniform powder. Moreover, blockage and uneven spraying are prone to occur during the dry ice conveying process, resulting in unstable cleaning effect. At the same time, there is a lack of precise control and anti-blocking design for the dry ice conveying process. Utility Model Content

[0004] The purpose of this invention is to provide a dry ice cleaning machine that adds block ice and shavings. Through a shaving structure composed of a blade holder and blades, block dry ice is pulverized. The processed dry ice powder falls into a storage refrigerator, where a feeding shaft, driven by a servo motor, ensures quantitative and uniform delivery of the dry ice powder, avoiding blockages and flow fluctuations during transport. A heating rod at the bottom of the storage refrigerator moderately heats the dry ice powder near the outlet pipe, preventing pipe blockage caused by excessive condensation at low temperatures. Simultaneously, the machine incorporates a backflushing function from the backflushing pipe, high-pressure airflow from the inlet pipe, and an automatic ice-feeding design from the ice-pushing plate, forming a complete process from adding, shaving, storing, quantitatively delivering, to stable spraying of block dry ice. This ultimately improves the efficiency, precision, and stability of dry ice cleaning, meeting the fine cleaning needs of precision molds, electronic components, and other applications.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7In this embodiment of the utility model, a machine housing 1 is included. A knife holder 7 is provided on one side inside the machine housing 1. A storage refrigerator 15 is fixedly connected to the bottom of the knife holder 7. A backflush pipe 14 is installed on one side above the storage refrigerator 15. A feeding shaft 11 is provided in the middle of the storage refrigerator 15. The feeding shaft 11 is rotatably connected to the storage refrigerator 15. A heating rod 12 is movably connected to the bottom of the storage refrigerator 15. An ice outlet pipe 13 is provided above the heating rod 12. The ice outlet pipe 13 is fixedly connected to the storage refrigerator 15.

[0025] By adopting the above technical solution, the chassis 1 serves as the overall supporting foundation of the equipment, providing stable installation space for the internal components. The blade holder 7 can carry ice-shaving parts to break up blocky dry ice and convert it into powder. The storage refrigerator 15 serves as a temporary storage place for dry ice powder, ensuring a continuous supply of dry ice during the cleaning process. The backflush pipe 14 is installed on one side above the storage refrigerator 15, which can clean the dry ice powder remaining on the inner wall of the storage refrigerator 15 through reverse airflow during the dry ice transportation process, preventing powder from caking and blocking the transportation channel, and ensuring the smooth transportation of dry ice.

[0026] Furthermore, the heating rod 12 at the bottom of the refrigerator 15 can generate moderate heat to slightly heat the dry ice powder near the ice outlet pipe 13, preventing the dry ice from condensing excessively at low temperatures and causing the ice outlet pipe 13 to become blocked. This provides a continuous and stable supply of dry ice for the final cleaning operation, effectively solving the problems of traditional dry ice cleaning machines in terms of block dry ice utilization and dry ice delivery stability.

[0027] In this embodiment, a first sprocket 8 is installed on the outer side of the tool holder 7. The first sprocket 8 is rotatably connected to the tool holder 7. A blade 19 is provided on the inner side of the tool holder 7. The blade 19 is rotatably connected to the tool holder 7. The blade 19 is fixedly connected to the first sprocket 8 by a pivot pin.

[0028] By adopting the above technical solution, when the first sprocket 8 is driven to rotate by the power of the second sprocket 10, it can directly drive the blade 19 to rotate synchronously, ensuring that the blade 19 obtains stable rotational power, thereby performing continuous and efficient planing operations on the blocky dry ice entering the blade holder 7 area, and converting the blocky dry ice into uniform powdery dry ice.

[0029] In this embodiment, a second sprocket 10 is fixedly connected to one side of the feeding shaft 11, and a servo motor 16 is installed on the other side. The servo motor 16 is fixedly connected to the bottom of the housing 1. The second sprocket 10 is connected to the first sprocket 8 through a toothed chain drive, and a tension sprocket 9 is meshed with one side of the toothed chain. The tension sprocket 9 is slidably connected to the refrigerator 15.

[0030] By adopting the above technical solution, the servo motor 16 can precisely control the speed, and can accurately control the ice-shaving efficiency of the blade 19 and the ice feeding amount of the feeding shaft 11. The tensioning sprocket 9 is slidably connected to the storage refrigerator 15, and can automatically tension the toothed chain by adjusting its own position, avoiding transmission lag or tooth skipping caused by chain loosening, ensuring efficient and reliable power transmission from the second sprocket 10 to the first sprocket 8, and reducing the problem of uneven dry ice powder particles or interruption of conveying caused by unstable transmission.

[0031] In this embodiment, a bracket 17 is fixedly connected to the upper part of the inside of the chassis 1, and an ice groove 4 is provided below the bracket 17 relative to the blade 19. The ice groove 4 is fixedly connected to the chassis 1. A slide 5 is installed on the bracket 17, and an ice pusher 6 is fixedly connected to the bottom of the slide 5.

[0032] By adopting the above technical solution, the ice tank 4 is fixed inside the machine box 1 and directly opposite the blade 19, ensuring that the dry ice can accurately enter the planing area of ​​the blade 19. The slide 5 on the bracket 17 drives the ice pusher 6 to reciprocate, which can continuously push the blocky dry ice in the ice tank 4 toward the blade 19, ensuring the stable production of dry ice powder.

[0033] In this embodiment, an air inlet pipe 18 is fixedly connected to the bottom of the refrigerator 15 on the side opposite to the ice outlet pipe 13.

[0034] By adopting the above technical solution, the air inlet pipe 18 can be connected to a high-pressure air source. After the high-pressure airflow enters the bottom of the refrigerator 15 through the air inlet pipe 18, it can blow the dry ice powder near the ice outlet pipe 13 from the feed shaft 11, ensuring that the dry ice powder can enter the cleaning operation in a high-speed and stable state.

[0035] In this embodiment, the surface of the feeding shaft 11 is provided with multiple grooves.

[0036] By adopting the above technical solution, the multiple grooves on the surface of the feeding shaft 11 can serve as a space for containing dry ice powder. When the feeding shaft 11 rotates, the grooves can scoop a fixed volume of dry ice powder from the refrigerator 15 and transport the powder to the vicinity of the ice outlet pipe 13 as it rotates. This allows for precise control of the amount of dry ice powder delivered each time, avoiding blockage of the ice outlet pipe due to excessive feeding or affecting cleaning efficiency due to insufficient feeding. It can flexibly adapt to the dry ice usage requirements of different cleaning scenarios.

[0037] In this embodiment, a backflush pipe 14 is fixedly connected to the outside of the refrigerator 15.

[0038] By adopting the above technical solution, the backflush pipe 14 can be connected to a high-pressure airflow. When the equipment is running or stopped, the high-pressure airflow is pushed back into the refrigerator 15 through the backflush pipe 14, which can blow off the residual dry ice powder attached to the inner wall of the refrigerator, the surface of the feed shaft 11 and the groove, so as to prevent the powder from condensing and clumping due to long-term retention, blocking the feed channel, and ensuring the continuous and stable delivery of dry ice powder.

[0039] Furthermore, the backflush airflow can disturb the dry ice powder inside the storage refrigerator 15, preventing it from forming a dense accumulation due to stagnation, keeping the powder in a loose state, making it easy for the groove of the feed shaft 11 to smoothly scoop up the powder, and reducing abnormal sublimation loss of dry ice caused by local compression, thereby improving the utilization rate of dry ice.

[0040] In this embodiment, a control panel 20 is provided on one side of the chassis 1, and an ice outlet 3 is fixedly connected to the bottom side of the control panel 20. The ice outlet 3 is fixedly connected to the ice outlet pipe 13.

[0041] By adopting the above technical solution, the control panel 20 integrates the core operating functions of the equipment. Operators can intuitively set parameters through the panel without touching the internal components of the equipment, and achieve precise control of ice shaving speed, ice delivery amount and cleaning intensity, reducing the complexity of operation and adapting to the needs of rapid switching between different cleaning scenarios.

[0042] In this embodiment, a flip-top plate 2 is provided on the top of the chassis 1 at a position perpendicular to the ice tank 4, and the flip-top plate 2 is movably connected to the chassis 1.

[0043] By adopting the above technical solution, the flip-top 2 is opened on the top of the chassis 1 and perpendicular to the ice tank 4. After opening the flip-top, the operator can directly put the block dry ice into the ice tank 4 from the top without disassembling other parts of the equipment, which simplifies the feeding process and ensures that the feeding process is smooth and efficient.

[0044] The working principle of this utility model is as follows: First, the operator opens the flip-top 2 of the top of the machine box 1, puts the block dry ice into the vertically corresponding ice trough 4, starts the equipment, and the slide 5 on the bracket 17 drives the ice pusher 6 to move along the ice trough 4, gradually pushing the block dry ice to the blade 19 inside the blade holder 7. At the same time, the servo motor 16 at the bottom of the chassis 1 starts, driving the feeding shaft 11 and the second sprocket 10 on one side to rotate. The second sprocket 10 transmits power to the first sprocket 8 outside the tool holder 7 through the toothed chain. The tensioning sprocket 9 adjusts the tension of the toothed chain in sync to ensure stable transmission and drive the blade 19 to rotate, shaving the pushed block of dry ice into uniform powdered dry ice. The dry ice powder after shaving falls into the storage refrigerator 15 below. The feeding shaft 11 rotates synchronously with the servo motor, quantitatively scooping the dry ice powder in the storage refrigerator 15 through the groove, and conveying the powder to the vicinity of the ice outlet pipe 13 at the bottom of the storage refrigerator as the shaft rotates. During this period, the back-blowing pipe 14 on the outside of the storage refrigerator 15 introduces high-pressure airflow to clean the residual powder in the inner wall of the storage refrigerator and the groove of the feeding shaft, preventing agglomeration and blockage. The air inlet pipe 18 at the bottom of the refrigerator 15 is connected to a high-pressure air source, which blows the dry ice powder conveyed by the feeding shaft 11 to the ice outlet pipe 13. At the same time, the heating rod 12 at the bottom of the refrigerator heats the dry ice powder appropriately to prevent the dry ice powder from condensing and clogging in the ice outlet pipe. The dry ice powder is finally conveyed through the ice outlet pipe 13 to the ice outlet 3 on one side of the machine box 1, and sprayed onto the surface to be cleaned with a high-speed airflow. After the cleaning operation is completed, the water removal mechanism inside the machine box 1 cleans up the dripping ice water inside the machine box 1.
