Description

Technical Field

[0001] This invention relates to the field of spiral quick-freezing technology, and in particular to an energy-saving spiral mesh belt quick-freezing device. Background Technology

[0002] Spiral quick-freezing machines are continuous low-temperature quick-freezing equipment that adopts a spiral mesh belt circulating conveyor structure. Relying on a multi-layer three-dimensional spiral layout, they save floor space. Combined with a low-temperature strong air circulation refrigeration system, they can quickly cool and lock in freshness for various foods. They can achieve large-scale continuous quick-freezing operations with uniform and stable freezing speed. The whole machine is made of food-grade stainless steel and is widely used in the rapid freezing processing of aquatic products, meat products, pastries, and pre-made foods.

[0003] Currently, operators frequently use spiral mesh belt quick-freezing devices when freezing aquatic products, meat products, and pastries. However, while existing quick-freezing devices possess basic food quick-freezing functions, ice easily condenses and accumulates on the stainless steel mesh belt during the freezing process. If this ice accumulation is not cleaned in time, the ice layer thickness will continue to increase, which not only reduces the device's quick-freezing efficiency but also increases the operating load to maintain normal quick-freezing effects, resulting in a significant increase in energy consumption. This reduces the overall operating efficiency of the device and increases production and operating costs, thus requiring improvement. Summary of the Invention

[0008] In a preferred embodiment, the bottom ends of both connecting shafts are fixedly connected to annular springs located inside the cavities of the two hollow blocks, and the ends of the two annular springs away from the two connecting shafts are fixedly connected to the cavities of the two hollow blocks.

[0009] In a preferred embodiment, a file is fixedly connected to the top end of the two connecting shafts, and the file has several slots on its outer surface.

[0010] In a preferred embodiment, two symmetrical ice blocks are fixedly connected to the top of the motion plate, with the two ice blocks located on either side of the file.

[0011] In a preferred embodiment, the fine de-icing mechanism includes a drive wheel with a slot inside, the inside of which is fixedly connected to the outside of the guide roller at the end away from the drive gear.

[0012] In a preferred embodiment, two symmetrical rectangular blocks are fixedly connected to one side of the connecting plate. Each rectangular block has a slot, and a long shaft is movably connected between the two slots. The end of the long shaft away from the driven gear passes through the rectangular block and extends to the outside of the rectangular block.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The energy-saving spiral mesh belt quick-freezing device disclosed in this invention is mainly applied to scenarios where energy consumption increases and operating efficiency decreases due to the failure to promptly remove ice condensed on the surface of the stainless steel mesh belt during the use of the quick-freezing device.

[0020] Reference Figures 1-9 An energy-saving spiral mesh belt quick-freezing device includes a housing 1, a quick-freezing machine 2 inside the housing 1, and an auxiliary energy-saving mechanism 3 on the outside of the housing 1. The auxiliary energy-saving mechanism 3 includes two connecting frames 301. One end of each connecting frame 301 is fixedly connected to the outside of the housing 1. The other end of each connecting frame 301 has a slot. A baffle roller 302 is movably connected between the two slots. Both ends of the baffle roller 302 pass through the two connecting frames 301 and extend to the outside of the two connecting frames 301. An anti-slip sleeve 303 is fixedly connected to the outside of the baffle roller 302. A drive gear 304 is fixedly connected to the outside of one end of the baffle roller 302. A connecting plate 305 located directly below the baffle roller 302 is fixedly connected to the outside of the housing 1. A mounting bracket 306 located below the drive gear 304 is fixedly connected to the outside of the housing 1. A fine de-icing mechanism 4 is provided on the auxiliary energy-saving mechanism 3.

[0021] In this invention, a driven gear 307 is rotatably connected to the outside of one end of the mounting bracket 306. The outside of the driven gear 307 meshes with the outside of the driving gear 304. Three first wedge blocks 308 are fixedly connected to the side of the driven gear 307 near the connecting plate 305. A second wedge block 309 is movably connected to the outside of one of the first wedge blocks 308. A round shaft 310 located inside the connecting plate 305 is fixedly connected to the side of the second wedge block 309 near the connecting plate 305. The round shaft 310 is movable within the connecting plate 305. Inside the slot of the connecting plate 305, a limiting block 311 is fixedly connected to the end of the round shaft 310 away from the second wedge block 309. The limiting block 311 moves within the slot of the connecting plate 305. A helical spring 312 is fixedly connected to the side of the limiting block 311 away from the round shaft 310. The end of the helical spring 312 away from the limiting block 311 is fixedly connected to the interior of the connecting plate 305. A moving plate 313 is fixedly connected to the top of the limiting block 311. The bottom end of the moving plate 313 is movably connected to the top of the connecting plate 305.

[0022] In this invention, the moving plate 313 has two symmetrical slots inside, and hollow blocks 314 are fixedly connected inside each slot. Connecting shafts 315 are movably connected inside each hollow block 314. The top ends of the two connecting shafts 315 pass through the two hollow blocks 314 and extend to the outside of the top ends of the two hollow blocks 314.

[0023] In this invention, the bottom ends of the two connecting shafts 315 are fixedly connected to annular springs 316 located in the inner cavities of the two hollow blocks 314, and the ends of the two annular springs 316 away from the two connecting shafts 315 are fixedly connected to the inner cavities of the two hollow blocks 314.

[0024] In this invention, a file 317 is fixedly connected to the top of the two connecting shafts 315, and the file 317 has several slots on its outside.

[0025] In this invention, two symmetrical ice blocks 318 are fixedly connected to the top of the motion plate 313, and the two ice blocks 318 are located on both sides of the file 317.

[0026] Specifically, after the quick-freezing machine 2 completes the food quick-freezing operation, its stainless steel mesh belt begins its return journey. Because the anti-slip sleeve 303 remains in close contact with the surface of the stainless steel mesh belt, friction drives the guide roller 302 to rotate synchronously. When the guide roller 302 rotates, it synchronously links with the drive gear 304 to achieve synchronous power transmission, eliminating the need for an additional drive mechanism and conforming to energy-saving design. During the rotation of the drive gear 304, its outer surface meshes with the driven gear 307, driving the driven gear 307 and three first wedge blocks 308 fixed on one side to rotate synchronously. The three first wedge blocks 308 are evenly distributed circumferentially. Intermittent contact and compression with the second wedge block 309 forces the second wedge block 309 to drive the round shaft 310, the limiting block 311, and the moving plate 313 to move to the right as a whole. At this time, the spiral spring 312 is compressed and stores energy. When the first wedge block 308 and the second wedge block 309 disengage and the compression effect disappears, the spiral spring 312 returns to its original position, pushing the limiting block 311 to drive the moving plate 313 to return to the left. This intermittent reciprocating motion drives the file 317 to move back and forth, filing and breaking the ice attached to the bottom of the stainless steel mesh belt, causing the ice to fall off naturally, reducing the load on the mesh belt, and reducing the energy consumption of the equipment.

[0027] In specific application scenarios, the anti-slip sleeve 303 is designed to prevent slippage when in contact with the stainless steel mesh belt. The linkage between the drive gear 304 and the guide roller 302 eliminates the need for operators to reinstall a drive source, further improving energy efficiency. The design of the three first wedge blocks 308 increases the squeezing frequency of the second wedge blocks 309, allowing the file 317 to better process the ice on the stainless steel mesh belt. The design of the two ice blocks 318 allows for the chipping of both ends of thick ice blocks. The cooperation between the two connecting shafts 315 and the two annular springs 316 enables the file 317 to adapt to different operating conditions.

[0028] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 In a preferred embodiment, the fine de-icing mechanism 4 includes a drive wheel 401, the drive wheel 401 having a slot inside, and the inside of the slot being fixedly connected to the outside of the end of the baffle roller 302 away from the drive gear 304.

[0029] In this invention, two symmetrical rectangular blocks 402 are fixedly connected to one side of the connecting plate 305. The interior of each rectangular block 402 is provided with a slot. A long shaft 403 is movably connected between the interior of the two slots. The end of the long shaft 403 away from the driven gear 307 passes through the rectangular block 402 and extends to the outside of the rectangular block 402. A cam 404 is fixedly connected to the outside of the long shaft 403.

[0030] In this invention, a driven wheel 405 is fixedly connected to the external side of the long shaft 403 away from the driven gear 307, and the driven wheel 405 is connected to the driving wheel 401 through the conveyor belt 406.

[0031] In this invention, two symmetrical limiting rods 407 are fixedly connected to the top of each of the two rectangular blocks 402. Two symmetrical movable plates 408 are movably connected to the outside of each of the two limiting rods 407. A vibrating plate 409 is fixedly connected between the opposite surfaces of the two movable plates 408. Tension springs 410 are movably connected to the outside of each of the two limiting rods 407. One end of each tension spring 410 away from the two rectangular blocks 402 is fixedly connected to the bottom end of the two movable plates 408. The other end of each tension spring 410 away from the two movable plates 408 is fixedly connected to the top of the two rectangular blocks 402.

[0032] Specifically, when the driving wheel 401 rotates, it drives the driven wheel 405 to rotate synchronously through the conveyor belt 406, which in turn drives the long shaft 403 and the cam 404 to rotate. During the rotation of the cam 404, it intermittently abuts against the bottom of the vibrating plate 409, pushing the vibrating plate 409 to drive the two movable plates 408 to move upward along the limit rod 407. At this time, the two tension springs 410 are stretched and stored energy. When the cam 404 rotates to the non-protruding end and disengages from the vibrating plate 409, the tension springs 410 return to their original position, pulling the movable plates 408 and the vibrating plate 409 back to their original position. The vibrating plate 409 moves back and forth, and its top end continuously collides and contacts the bottom end of the stainless steel mesh belt. The vibration effect shakes off the small ice fragments remaining on the surface of the mesh belt and in the mesh holes, further cleaning the mesh belt.

[0033] Working Principle: After the quick-freezing machine 2 completes the food quick-freezing operation, its stainless steel mesh belt begins its return journey. Because the anti-slip sleeve 303 remains in close contact with the surface of the stainless steel mesh belt, friction drives the guide roller 302 to rotate synchronously. When the guide roller 302 rotates, it synchronously links the drive gear 304 and the drive wheel 401, achieving synchronous power transmission. No additional drive mechanism is required, aligning with energy-saving design. During the rotation of the drive gear 304, its outer surface meshes with the driven gear 307, driving the driven gear 307 and three first wedge blocks 308 fixed on one side to rotate synchronously. The three first wedge blocks 308 are evenly distributed circumferentially. During rotation, they intermittently abut and press against the second wedge block 309, forcing the second wedge block 309 to drive the circular shaft 310, the limit block 311, and the moving plate 313 to move to the right as a whole. At this time, the spiral spring 312 is compressed and stores energy. When the first wedge block 308 disengages from the second wedge block 309 and the pressure dissipates... After the effect disappears, the helical spring 312 returns to its original position, pushing the limit block 311 to drive the moving plate 313 to return to the left. This intermittent reciprocating motion drives the file 317 to move back and forth, filing and breaking the ice attached to the bottom of the stainless steel mesh belt, allowing the ice fragments to fall off naturally, reducing the load on the mesh belt and lowering the energy consumption of the equipment. When the file 317 encounters a thick ice layer, the thick ice layer exerts downward pressure on the file 317, forcing the file 317 to drive the two connecting shafts 315 to contract into the cavity of the hollow block 314. The two ring springs 316 are compressed, forming a buffer effect to prevent damage to the file or the mesh belt. At the same time, the two ends of the thick ice layer are exactly between the two ice fragments 318. While the file 317 is filing the thick ice layer back and forth, the two ice fragments 318 are simultaneously chiseling at the two ends of the thick ice layer. Under the dual action, the thick ice layer is quickly broken and falls off, completely removing the ice accumulation on the surface of the mesh belt and preventing the accumulation of ice from increasing the running resistance of the mesh belt and additional energy consumption.

[0034] Meanwhile, when the active wheel 401 rotates, it drives the driven wheel 405 to rotate synchronously through the conveyor belt 406, which in turn drives the long shaft 403 and the cam 404 to rotate. During the rotation of the cam 404, it intermittently abuts against the bottom end of the vibrating plate 409, pushing the vibrating plate 409 to drive the two movable plates 408 to move upward along the limit rod 407. At this time, the two tension springs 410 are stretched and stored energy. When the cam 404 rotates to the non-protruding end and disengages from the vibrating plate 409, the tension springs 410 return to their original position, pulling the movable plates 408 and the vibrating plate 409 back to their original position. The vibrating plate 409 moves back and forth, and its top end continuously collides and contacts the bottom end of the stainless steel mesh belt. The vibration effect shakes off the small ice fragments remaining on the surface of the mesh belt and in the mesh holes, further cleaning the mesh belt, ensuring smooth operation of the mesh belt, reducing equipment energy consumption from the source, and ensuring the stable and efficient operation of the quick-freezing device.
