Description

Technical Field

[0001] The invention relates to the technical field of snow and ice machines, and in particular to a waterproof structure for an ice-making roller shaft end of a household snow and ice machine. Background Art

[0002] Snow ice machine is a device that can freeze liquid mixture into fine granular snowflake ice cubes. It looks like fresh snowflakes, has a fine and fluffy texture, and is very suitable for catering, laboratories and other applications that require special ice cubes. This device usually consists of a freezing chamber, an electric blade or roller, and a collection tray. It makes snowflake ice cubes by freezing the liquid mixture and cutting it into thin slices. Snow ice machine plays an important role in catering services. It can make drinks such as shaved ice, snow cones, and smoothies, providing a refreshing taste for drinks and desserts, while improving the visual presentation of dishes, especially suitable for summer sales. In addition, it can also be used to make snow ice desserts with a variety of flavors to meet the personalized needs of consumers. The laboratory-specific snow ice machine is mainly used to prepare fine granular snowflake-shaped crushed ice. This ice has good cooling effect and fast permeability, and is suitable for life sciences, medicine, agriculture, forestry, animal husbandry and fishery and other fields. For example, it can be used for low-temperature operations such as PCR reactions, genomic DNA extraction, and cell culture. Industrial snow ice machines are widely used in seafood preservation, food processing, concrete cooling and other fields. Its characteristics are efficient ice making, low energy consumption and rapid cooling, which can effectively extend the shelf life of the product. With the advancement of technology and the growth of market demand, snow ice machines are developing in the direction of intelligence and multi-function. For example, some new equipment integrates the function of flavor injection, which can customize the flavor of snow ice according to personal preferences. In addition, the use of environmentally friendly refrigerants and the application of energy-saving technologies also make snow ice machines more in line with the requirements of modern sustainable development.

[0003] The household snow ice machine uses a compressor refrigeration system to cool the ice roller shaft. The ice roller shaft contacts the liquid in the liquid storage box to make an ice film adhere to the surface of the ice roller. The ice roller rotates continuously during operation and contacts the ice knife group. The ice knife group scrapes the ice film on the ice roller to form a finished ice smoothie, completing the ice making process. When the snow ice machine is in use, liquid infiltration or condensation will occur at both ends of the roller shaft due to long-term use of the machine. Since the roller shaft is a metal product, moisture will cause the metal roller shaft to rust, thus affecting its service life and performance. Waterproofing can effectively prevent moisture intrusion and reduce the risk of corrosion. This reduces failures and maintenance caused by moisture, extends the service life of the machine, and reduces operating costs.

[0004] In existing snow ice machines, the ice roller needs to rotate, resulting in a gap between the ice roller and the main part, which is prone to water seepage or other beverages such as milk. Conventional practices also add non-removable structures such as oil seals and waterproof shaft seals to prevent water from entering. And this structure cannot be disassembled for cleaning. The two ends of the roller are often directly connected to the machine body, which is not well protected, and it is easy for the liquid generated on the roller to contact the rotating shaft at both ends of the roller, causing corrosion of the rotating shaft, affecting its service life and safety performance.

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1 Combine the following Figure 1-Figure 8 The invention discloses a waterproof structure for the shaft end of an ice-making roller of a household snow and ice machine.

[0024] like Figure 1-Figure 8As shown, an embodiment of the present invention provides a waterproof structure for the shaft end of an ice roller of a household snow ice machine, comprising: a roller shaft 1 and two waterproof mechanisms 2. The two waterproof mechanisms 2 are detachably connected to the two ends of the roller shaft 1, and are used for waterproofing the two ends of the roller shaft 1. Since the ice roller needs to rotate, there is a gap at the connection between the ice roller and the main part (shell or frame), which is prone to water seepage or other beverage conditions such as milk. For example, it is easy to mold and breed bacteria. Conventional practices also add non-detachable structures such as oil seals and waterproof shaft seals to prevent water from entering. And this structure cannot be disassembled and cleaned. The two ends of the roller shaft are mostly directly connected to the machine body, and the protection is insufficient, which easily causes the liquid generated on the roller shaft to contact the rotating shaft at both ends of the roller shaft, causing corrosion of the rotating shaft, affecting its service life and safety performance. During the operation of the snow ice machine, the two ends of the roller shaft 1 may be exposed to moisture, especially in a humid environment. Moisture can cause the metal roller shaft to rust, thereby affecting its service life and performance. Through waterproofing, moisture intrusion can be effectively prevented and the risk of corrosion can be reduced. Thereby reducing failures and maintenance caused by moisture, extending the service life of the machine, and reducing operating costs. The waterproof mechanism 2 includes a connection module 21 and a waterproof module 22. The connection module 21 is used to connect the roller shaft 1 and the waterproof module 22, so that the waterproof module 22 can act on the roller shaft 1. The connection module 21 is rotatably connected to the roller shaft 1. When the roller shaft 1 rotates, it will not drive the connection module 21 to rotate, and further will not drive the waterproof module 22 to rotate. The waterproof module 22 is detachably connected to the connection module 21. The detachable connection method can ensure that the machine can be easily disassembled and replaced when it is repaired later, thereby increasing the overall service life of the machine.

[0025] The roller 1 includes a roller body 11 and two rotating shafts 12. The roller 1 is usually made of metal materials, such as food-grade stainless steel. Food-grade stainless steel is a special stainless steel material that meets food safety requirements and is mainly used in food processing, storage and transportation equipment. Its main features include non-toxicity, strong corrosion resistance, easy cleaning, and good high-temperature stability. Common food-grade stainless steel types include 304 and 316L, of which 304 is the most commonly used one and is suitable for general food processing; 316L contains molybdenum, which is more suitable for high-salt and high-acid environments.

[0026] Limiting grooves 111 are provided at both ends of the roller body 11 for limiting the connection module 21. The limiting groove 111 is annular. When the connection module 21 is installed in the limiting groove 111, the connection module 21 is more stable. And the connection module 21 and the limiting groove 111 are rotatably connected. The main function of the connection module 21 is to connect the waterproof module 22 to the roller shaft 1. The rotation of the roller shaft 1 will not affect the state of the connection module 21. The two rotating shafts 12 are fixedly connected at both ends of the roller body 11. The end of the rotating shaft 12 away from the roller body 11 is connected to a driving device or a motor for driving the roller shaft 1 to rotate.

[0027] The connection module 21 includes a connection bracket 211, a diffusion component 212, a transmission component 213 and a control component 214. The connection bracket 211 is used to fix the transmission component 213 and the control component 214, and the control component 214 is used to control the diffusion component 212 so that it is rotationally connected to the roller body 11. The connection bracket 211 is the main frame of the connection module 21, and is usually designed according to the requirements of each component connected thereto. The connection bracket 211 is divided into an inner and outer layer structure: the inner layer structure is used to fix the diffusion component 212 and the transmission component 213, and the outer layer is used to fix the control component 214 and the outer layer of the connection roller body 11.

[0028] The waterproof module 22 includes two plugging components 221, a silicone sealing ring 222 and a sealing plate 223. The two plugging components 221 are symmetrically arranged in the connecting bracket 211 and abut against the rotating shaft 12. It is mainly used to prevent liquid from penetrating through the waterproof module 22. A plurality of drainage grooves are provided in the connecting bracket 211, and the waterproof grooves are connected to the outside of the connecting bracket 211, which can effectively guide the water that penetrates into the connecting bracket 211 out of the waterproof mechanism 2, thereby further achieving the purpose of waterproofing. And this drainage structure is crucial to prevent liquid accumulation and potential damage, ensuring that the equipment can still work normally in harsh environments. A sealing groove 2111 is provided on the connecting bracket 211, and the sealing groove 2111 is provided on the side of the connecting bracket 211 away from the roller body 11, and the sealing groove 2111 is a circular ring coaxial with the connecting bracket 211. The silicone sealing ring 222 is provided in the sealing groove 2111, and the sealing plate 223 abuts against the silicone sealing ring 222. The silicone seal ring 222 is used to improve the sealing performance between the sealing plate 223 and the connecting bracket 211. The silicone seal ring 222 is generally made of carbon ceramic material. The carbon ceramic flange is a flange made of a ceramic material composed of carbon and carbide, and has excellent corrosion resistance, wear resistance, high temperature resistance, pressure resistance and sealing performance.

[0029] The sealing component 221 includes a pressing plate 2211 and a spring 2212. The pressing plate 2211 is in a semi-annular shape, which can completely wrap the radial surface of the rotating shaft 12, thereby forming a tight sealing area on the outside of the rotating shaft 12. The two ends of the spring 2212 are fixedly connected to the pressing plate 2211 and the connecting bracket 211 respectively, and the pressing plate 2211 abuts against the rotating shaft 12. This connection method enables the pressing plate 2211 to always maintain a tight fit with the rotating shaft 12 under the elastic action of the spring 2212. This tight fit relationship can effectively prevent liquid from penetrating through the gap between the rotating shaft 12 and the pressing plate 2211, thereby providing a reliable waterproof effect for the entire device. Through the elastic support of the spring 2212, the pressing plate 2211 can maintain stable sealing performance under different working conditions, and even when the rotating shaft 12 vibrates or displaces slightly, the reliability of the seal can be ensured.

[0030] The waterproof module 22 also includes two fastening components 224 and an adjusting disk 225. These components work together to further enhance the sealing performance of the entire waterproof module. The two fastening components 224 are used to fasten the sealing plate 223 and the silicone sealing ring 222, so that the sealing plate 223 can press the silicone sealing ring 222 tightly, and at the same time, the sealing plate 223 and the connecting bracket 211 can fit together more tightly, further reducing the path that liquid may penetrate. The adjusting disk 225 is screwed to the sealing plate 223 and is used to adjust the tightness of the fastening component 224. By accurately adjusting the fastening force of the fastening component 224, it can be ensured that the sealing pressure between the sealing plate 223 and the silicone sealing ring 222 reaches the optimal state, thereby improving the sealing performance and reliability of the entire waterproof module.

[0031] The fastening assembly 224 includes an adjusting rod 2241, an adjusting gear 2242, a screw 2243 and a limit block 2244. The adjusting rod 2241 is rotatably connected to the connecting bracket 211 and the sealing plate 223 respectively. The adjusting rod 2241 is mainly divided into two parts, one part is connected to the connecting bracket 211, and the other part is connected to the sealing plate 223, and the two parts are detachably connected by screws. According to the lever principle, if the other end of the adjusting rod 2241 moves inward or outward, the end connected to the remaining connecting bracket 211 will pull or push the connecting bracket 211, thereby affecting the tightness of the connection between the connecting bracket 211 and the sealing plate 223. The screw 2243 is screwed to the adjusting rod 2241. When the screw 2243 is rotated, the adjusting rod 2241 will move along the screw 2243, thereby controlling the movement of the other end of the adjusting rod 2241. The screw rod 2243 is movably connected to the sealing plate 223 and the connecting bracket 211. This connection mode ensures the free rotation of the screw rod 2243 and its stability during movement. One end of the screw rod 2243 is fixedly connected to the adjusting gear 2242, and the other end is detachably connected to the limit block 2244. The limit block 2244 is mainly used to prevent the screw rod 2243 from falling off, thereby avoiding the failure of the waterproof mechanism 2 caused by the screw rod 2243 falling off. The shape of the adjusting disk 225 is a "barrel" shape, and its inner wall is provided with two sets of centrally symmetrical racks, which are fixedly connected to the inner wall of the adjusting disk 225 and meshed with the adjusting gear 2242. When the adjusting disk 225 is rotated, the adjusting gear 2242 will rotate along with the adjusting disk 225, thereby driving the screw rod 2243 to rotate. The screw rod 2243 will cause the end of the adjusting rod 2241 in contact with the screw rod 2243 to move toward the direction close to the sealing plate 223, thereby causing the other end of the adjusting rod 2241 to pull the connecting bracket 211, thereby making the connection between the connecting bracket 211 and the sealing plate 223 tighter, thereby improving the waterproof performance of the waterproof mechanism 2.

[0032] The diffusion assembly 212 is a structure for adjusting the cooperation with the roller body 11, including a plurality of diffusion plates 2121 and a plurality of moving blocks 2122. The plurality of moving blocks 2122 are fixedly connected to the diffusion plates 2121 respectively. The diffusion plates 2121 are in the shape of a fan. When they are gathered together, the plurality of diffusion plates 2121 can fit perfectly to form a complete circular structure, which improves the overall stability of the diffusion assembly 212 and ensures its accuracy when it cooperates with the roller body 11. The moving blocks 2122 drive the diffusion plates 2121 to slide outward, thereby increasing the diameter of the diffusion assembly 212, thereby realizing the dynamic adjustment of the diameter of the diffusion assembly 212. When the diameter of the diffusion assembly 212 increases, its outer edge can be precisely fitted with the limiting groove 111 opened on the roller body 11. The limiting groove 111 is to provide a stable positioning structure to ensure that the diffusion assembly 212 always maintains a close fit with the roller body 11 during operation to prevent loosening due to external force or vibration. The diffusion assembly 212 can be quickly installed and disassembled.

[0033] The transmission assembly 213 includes a fixed disk 2131, a driving bevel gear 2132, a plurality of transmission bevel gears 2133 and a plurality of transmission screws 2134. Through precise mechanical connection and transmission cooperation between the components, efficient power transmission and precise motion control are achieved. The fixed disk 2131, as the basic structure of the transmission assembly, provides stable support and positioning for the entire transmission assembly 213. The fixed disk 2131 is fixedly connected to the connecting bracket 211. A plurality of moving blocks 2122 are respectively screwed with a plurality of transmission screws 2134 and are slidably connected with the fixed disk 2131. The plurality of moving blocks 2122 can move along the transmission screws 2134 connected to them, and due to the limitation of the fixed disk 2131, they will not rotate on the transmission screws 2134. The plurality of transmission screws 2134 are respectively rotatably connected with the fixed disk 2131, and the plurality of transmission bevel gears 2133 are respectively fixedly connected with the plurality of transmission screws 2134, and the plurality of transmission bevel gears 2133 are all meshed with the driving bevel gear 2132. The driving bevel gear 2132 rotates to drive the multiple transmission bevel gears 2133 to rotate simultaneously, thereby causing the multiple transmission screws 2134 to rotate, driving the moving block 2122 to move, and then causing the diffusion plate 2121 to diffuse outward or contract inward, thereby achieving the purpose of connecting and disconnecting the connection module 21. When the diffusion plate 2121 diffuses outward, its diameter increases, and it can fit tightly with the limiting groove 111 on the roller body 11. When the diffusion plate 2121 contracts inward, its diameter decreases, which facilitates separation from the roller body 11, thereby achieving the function switching of connecting and disconnecting the connection module 21.

[0034] The control assembly 214 includes a gear 2141, a fixing pin 2142 and a knob 2143. The gear 2141 is fixedly connected to the knob 2143 so that the rotation of the knob 2143 can directly drive the gear 2141 to rotate synchronously. This integrated connection method simplifies the transmission path and improves the transmission efficiency and reliability. The gear 2141 is meshed with the driving bevel gear 2132 to form an efficient transmission chain. When the knob 2143 is manually rotated, the gear 2141 rotates accordingly and drives the driving bevel gear 2132 to rotate through the meshing relationship. Since there is a meshing relationship between the driving bevel gear 2132 and the driving bevel gear 2133, its rotation will be further transmitted to the transmission screw 2134, thereby driving the transmission screw 2134 to rotate. The rotation of the transmission screw 2134 is converted into the linear motion of the moving block 2122 through the threaded transmission, and finally realizes the outward diffusion or inward contraction action of the diffusion plate 2121. The knob 2143 is rotatably connected to the connecting bracket 211, and the fixing pin 2142 is slidably connected to the knob 2143. When the diffuser 2121 diffuses to the preset position, the fixing pin 2142 is inserted into the knob 2143 to fix the knob 2143. This locking mechanism can effectively prevent the knob 2143 from accidentally rotating due to spontaneous rotation or external vibration, thereby ensuring that the diffuser 2121 always remains in the set position during operation, thereby improving the stability and reliability of the device. The operation of the knob 2143 is simple and intuitive. The state switching of the diffuser 2121 is achieved by manually rotating the knob without the need for complex tools or skills. At the same time, the locking and unlocking process of the fixing pin 2142 is also very simple, and the locking or releasing operation can be quickly completed according to actual needs. It not only improves work efficiency, but also reduces the risk of operating errors, making the entire device easier to operate and maintain in actual applications.

[0035] In summary, the working principle of the waterproof structure of the ice roller shaft end of a household snow and ice machine of the present invention is described below: during installation, first insert the connection module 21 into the rotating shaft 12 until the connection module 21 contacts the roller body 11, pull out the fixing pin 2142, rotate the knob 2143, the knob 2143 will control the gear 2141 to rotate, and then drive the driving bevel gear 2132 to rotate, further drive multiple transmission bevel gears 2133 to rotate, so that multiple moving blocks 2122 move along multiple transmission screws 2134 in a direction away from the rotating shaft 12, and further drive multiple diffusion plates 2121 to move in the same direction. When the diffusion plate 2121 moves to the preset position, the fixing pin 2142 is inserted back into the knob 2143. Because the adjustment rod 2241 is mainly divided into two parts, one part is connected to the connecting bracket 211, and the other part is connected to the sealing plate 223, and the two parts are detachably connected by screws. The silicone seal ring 222 is placed in the sealing groove 2111, and the sealing plate 223 is abutted against the silicone seal ring 222. The transmission screw 2134 passes through one end of the adjustment rod 2241, and passes through the sealing plate 223 and the connecting bracket 211 at the same time, and then the limit block 2244 is connected to the other end of the transmission screw 2134. The adjustment disk 225 is coaxially arranged with the sealing plate 223, and it is screwed on the sealing plate 223. At the same time, the gear teeth on the adjustment disk 225 will drive the adjustment gear 2242 to rotate, thereby rotating the screw rod 2243. The rotation of the screw rod 2243 can make the other end of the adjustment rod 2241 tighten the connecting bracket 211, so that the connecting bracket 211 and the sealing plate 223 are more closely connected. At the same time, the pressing sheet 2211 in the blocking component 221 will be in close contact with the rotating shaft 12 under the action of the spring 2212, thereby achieving the purpose of blocking liquid penetration.
