Description

Technical Field

[0001] The invention belongs to the technical field of food processing, and particularly discloses a spiral quick-freezing tunnel device for food processing. Background Art

[0002] In the modern food processing industry, quick-freezing technology, with its ability to effectively preserve food nutrients and extend shelf life, has become a key technology for ensuring food quality and safety. Due to its high efficiency and continuous operation, spiral quick-freezing tunnel equipment is widely used in the production process of quick-frozen foods, fulfilling the core tasks of quick freezing, conveying, and discharging materials.

[0003] In the existing spiral quick-freezing tunnel equipment for food processing, during the material discharging process, water may form ice crystals connecting with the surface of the conveyor belt after freezing during the freezing process, causing the material to stick to the surface of the conveyor belt during discharge.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The stabilizing plate and protective assembly form a dual-stabilization structure. When the conveyor belt is carrying a large amount of material or is affected by the vibration of the cam rod, the stabilizing plate uses its outer limiter to control the conveyor belt deviation to a very small range. The L-shaped stabilizing plate cooperates with the spring to float up and down with the conveyor belt in real time, ensuring that the conveyor belt can maintain stable operation even if the material weight is unevenly distributed, significantly reducing the risk of material falling due to shaking. The cleaning cylinder, cleaning blades, and push plate form a three-dimensional cleaning system. The cleaning cylinder rotates to clean residual materials from the bottom of the conveyor belt. The cleaning blade slides back and forth along the guide post, like a precision scraper, reaching deep into the gaps between the cleaning cylinder brushes to thoroughly remove accumulated dust. The push plate collects scattered dust. This cleaning method, from the surface to the gaps and then to centralized processing, effectively prevents secondary contamination of materials by dust and meets the strict hygiene standards of food processing. The material receiving box and cleaning components form a self-cleaning closed-loop system. Dust scraped by the cleaning blade falls directly into the material receiving box, and the pushing plate pushes the dust to the designated location. Workers only need to open the material receiving box regularly for cleaning, eliminating the need for complex manual cleaning inside the equipment, greatly reducing cleaning workload and labor costs. From the rapid diversion and loading of materials through the inclined plate, to the full process automation of quick freezing, vibration stripping and automatic cleaning, the equipment realizes seamless continuous production. Compared with traditional equipment with manual assisted stripping and cleaning, it greatly increases the material processing volume per unit time and significantly improves production efficiency.

[0016] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1-8 The spiral quick-freezing tunnel equipment shown in the figure for food processing includes a spiral quick-freezing machine 1, which includes an input port 2 and an output port 3. The input port 2 and the output port 3 are respectively located at the two ends of the spiral quick-freezing machine 1. A conveyor belt is connected between the spiral quick-freezing machine 1, the input port 2 and the output port 3. An outer cover 6 is provided on the outer side of the conveyor belt of the output port 3. A vibration mechanism 32 is provided inside the outer cover 6. The vibration mechanism 32 includes a cam rod 11 and a protective assembly. The cam rod 11 is rotatably installed in the middle of the conveyor belt. The protective assembly is installed above the conveyor belt. A material receiving mechanism 31 is provided below the outer cover 6. The material receiving mechanism 31 includes a material receiving box 21. The interior of the material receiving box 21 A cleaning cylinder 20 and a dust cleaning component are provided. The cleaning cylinder 20 corresponds to the bottom surface of the conveyor belt. The ends of the cam rod 11 and the cleaning cylinder 20 both pass through the outer cover shell 6, and the ends of the cam rod 11 and the cleaning cylinder 20 on the same side are respectively installed with a first synchronous wheel 8 and a second synchronous wheel 9. A synchronous belt 10 is connected between the first synchronous wheel 8 and the second synchronous wheel 9. Under the action of the vibration mechanism 32 and the material receiving mechanism 31, the device automatically operates in the entire process from rapid material diversion and loading through the inclined plate 5 to quick freezing, vibration stripping, and automatic cleaning. The equipment realizes seamless continuous production. Compared with traditional manually assisted stripping and cleaning equipment, the material processing volume per unit time is greatly improved, and the production efficiency is significantly improved.

[0019] A stepper motor is provided on the surface of the outer cover shell 6 away from the synchronous belt 10, and the output end of the stepper motor is connected to the cam rod 11. When the material reaches the output port 3 along the conveyor belt and enters the outer cover shell 6, the stepper motor starts according to the preset program and drives the cam rod 11 to rotate. The eccentric structure of the cam rod 11 causes the conveyor belt to vibrate periodically, causing the frozen material to fall off.

[0020] A stabilizing plate 7 is provided on the inner wall of the outer cover shell 6. The stabilizing plate 7 is located on the outside of the conveyor belt. Notches are provided on the surfaces of the upper and lower ends of the stabilizing plate 7. The two notches correspond to the protective component and the material receiving box 21 respectively. When the conveyor belt carries the material through the output port 3, the stabilizing plate 7 can suppress the deviation or shaking of the conveyor belt caused by the weight or vibration of the material, thereby ensuring the stability of the transmission path. The upper end notch provides installation space for the protective component so that the protective component can extend above the conveyor belt without interfering with the stabilizing plate 7. The lower end notch is aligned with the material receiving box 21 to ensure that the fallen material can smoothly pass through the notch and fall into the material receiving box 21 to avoid being blocked by the stabilizing plate 7.

[0021] The protection assembly includes a protection frame 25, which is fixedly installed on the top of the outer cover shell 6 by bolts. Two trapezoidal blocks 26 are symmetrically installed on the inner wall of the protection frame 25. The bottom end of the trapezoidal block 26 is movably provided with an L-shaped stabilizing piece 27, which is movably located in the notch. A T-shaped rod 28 is fixedly installed on the surface of the L-shaped stabilizing piece 27. A storage groove 29 is provided inside the trapezoidal block 26. The top of the T-shaped rod 28 is movably inserted into the storage groove 29, and a spring 30 is provided inside the storage groove 29. The bottom end of the spring 30 is connected to the T-shaped rod 28. The protection frame 2 The L-shaped stabilizer 27 is fixed to the outer cover 6 by bolts. The trapezoidal block 26 on its inner wall provides a mounting base for the L-shaped stabilizer 27. The bottom of the L-shaped stabilizer 27 is inserted into the upper notch of the stabilizer plate 7. The top of the L-shaped stabilizer 27 is connected to the receiving groove 29 in the trapezoidal block 26 via a T-shaped rod 28. The spring 30 in the receiving groove 29 exerts a downward thrust on the T-shaped rod 28. When the conveyor belt moves up and down due to the vibration of the cam rod 11 or the weight of the material, the L-shaped stabilizer 27 can float synchronously with the conveyor belt. The protective component is used to prevent material from falling to the outside of the conveyor belt due to vibration when the cam rod 11 is working.

[0022] The dust cleaning assembly includes a cleaning sheet 24, which is movably mounted inside the material receiving box 21, and the surface of the cleaning sheet 24 corresponds to the bottom of the cleaning cylinder 20. A positioning post 22 is fixedly mounted at the middle end of the material receiving box 21 and on both sides of the cleaning cylinder 20. A guide post 23 is fixedly connected between the two positioning posts 22. The bottom end of the cleaning sheet 24 is slidably mounted on the surface of the guide post 23, and the cleaning sheet 24 is slidingly sleeved on the surface of the guide post 23 through the bottom end, and can slide freely along the axial direction of the guide post 23. When it is necessary to clean the accumulated dust at the bottom of the cleaning cylinder 20, the cleaning sheet 24 slides back and forth along the guide post 23 toward the cleaning cylinder 20. The surface of the cleaning sheet 24 fits tightly against the bottom of the cleaning cylinder 20. During the sliding process, the dust attached to the brush on the surface of the cleaning cylinder 20 is scraped off, and the scraped dust falls into the material receiving box 21. The material receiving box 21 can be opened and cleaned regularly to realize centralized collection and treatment of dust.

[0023] A disc 12 is fixedly mounted on the end of the second synchronous wheel 9, a protruding column 13 is fixedly mounted on the end of the disc 12, a swing rod 14 is movably mounted on the surface of the disc 12, a center groove 15 is provided on the surface of the swing rod 14, and the center groove 15 is sleeved on the surface of the protruding column 13, and two support columns 17 are symmetrically mounted on the surface of the material receiving box 21, and the two support columns 17 are respectively arranged on both sides of the second synchronous wheel 9, and polished rods 16 are symmetrically mounted on both sides of the swing rod 14, and the two polished rods 16 are respectively movably passed through the two support columns 17, and a first through-groove 19 is provided on the surface of the material receiving box 21, and the first through-groove 19 is located below the second synchronous wheel 9, and a first connecting column 18 is movably provided inside the first through-groove 19, and one end of the first connecting column 18 is fixedly connected to the cleaning sheet 24 inside the material receiving box 21, and the other end of the first connecting column 18 is fixedly connected to the bottom of the swing rod 14 When the second synchronous wheel 9 rotates, it drives the coaxial disc 12 to rotate synchronously, and the protruding column 13 at the end of the disc 12 performs a circular motion accordingly. The swing rod 14 is sleeved on the protruding column 13 through the center groove 15. The circular motion of the protruding column 13 forces the swing rod 14 to swing back and forth around the axis of the support column 17. The light rods 16 on both sides of the swing rod 14 respectively penetrate the support column 17. The support column 17 limits the light rod 16 to slide only along the axial direction to ensure that the swing trajectory of the swing rod 14 is stable. The first connecting column 18 at the bottom of the swing rod 14 moves synchronously with the swing rod 14, and the swing is converted into a linear reciprocating motion of the cleaning sheet 24 through the first through-groove 19 on the surface of the material receiving box 21. The cleaning sheet 24 slides back and forth on the guide column 23, and its surface pushes the brush on the surface of the cleaning cylinder 20, so that the dust remaining between the brushes can be scraped off, the accumulated dust is scraped off and the dust is pushed into the material receiving box 21.

[0024] A second through groove 33 is provided on the surface of the material receiving box 21 and on the side of the first through groove 19. A second connecting post 34 is movably installed inside the second through groove 33. A pushing plate 35 is provided at the bottom end of the inner cavity of the material receiving box 21. One end of the second connecting post 34 inside the material receiving box 21 is fixedly connected to the pushing plate 35, and the other end of the second connecting post 34 is fixedly connected to the optical rod 16. The movement of the optical rod 16 is transmitted to the pushing plate 35 through the second connecting post 34, so that it performs a reciprocating pushing motion at the bottom of the inner cavity of the material receiving box 21. After the cleaning sheet 24 scrapes the dust into the material receiving box 21, the pushing plate 35 moves back and forth along the bottom of the material receiving box 21, pushing the dust to the side of the designated material receiving box 21 to prevent dust from accumulating at the bottom of the material receiving box 21.

[0025] A discharge platform 4 is provided at the end of the output port 3, and an inclined panel 5 is provided on the top of the discharge platform 4. The inclined panel 5 is close to the surface of the conveyor belt. When the material from the output port 3 is transported through the discharge platform 4, the inclined panel 5 is close to the surface of the conveyor belt at an inclined angle to form a guide channel. After the material falls from the output port 3, it slides along the inclined surface of the inclined panel 5 to complete the collection of the material.

[0026] Working principle: First, the conveyor belt drives the material into the spiral quick-freezing machine 1 and moves slowly along the spiral trajectory. The frozen material arrives at the output port 3 along the conveyor belt and enters the inner part of the outer cover shell 6. The stepper motor is started according to the preset program, driving the cam rod 11 to rotate. The eccentric structure of the cam rod 11 squeezes the conveyor belt, causing it to vibrate periodically, causing the frozen material attached to the conveyor belt to fall off and avoid material residue. When the cam rod 11 rotates, the second synchronous wheel 9 is driven to rotate through the first synchronous wheel 8 and the synchronous belt 10, driving the disc 12 to rotate. The protruding column 13 on the disc 12 makes a circular motion, and the swing rod 14 is driven to swing back and forth around the support column 17 through the center groove 15. The polished rod 16 slides axially along the support column 17, driving the cleaning sheet 24 to slide back and forth on the guide column 23 to scrape off the dust on the brush of the cleaning cylinder 20. When the polished rod 16 moves, it drives the pushing plate 35 to push back and forth at the bottom of the material receiving box 21 through the second connecting column 34, and pushes the dust scraped off by the cleaning sheet 24 to the side ash hopper to avoid accumulation affecting the next material removal.
