Description

Technical Field

[0001] This invention relates to the field of food conveying technology, specifically to a multi-layer stacked conveying device for food conveying. Background Technology

[0002] With the continuous improvement of automation in the food processing industry, multi-layer stacked conveyor devices are widely used in the sorting, cooling, buffering and packaging of chicken, beef and other meat products. By stacking multiple conveyor belts, the conveying path can be extended in a limited space, improving conveying efficiency and production continuity.

[0003] Most existing food conveying devices use food-grade flat conveyor belts to continuously transport chicken meat. However, chicken meat inevitably carries blood, oil, meat scraps, and small bone fragments during processing. As the conveyor belt continues to run, these substances easily remain on the surface of the conveyor belt.

[0004] Currently, although some conveying devices are equipped with scraper structures to scrape and clean blood and meat scraps from the surface of the conveyor belt, existing scrapers usually adopt a fixed rigid pressing structure. In actual use, when bone fragments, hard bone debris, or other hard foreign objects are attached to the surface of the conveyor belt, the hard objects are easy to directly squeeze and collide with the scraper, which can easily cause local wear, deformation, or even jamming of the scraper, thus affecting the conveying of materials. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-layer stacked conveying device for food conveying, which solves the problem that scrapers, which typically employ a rigid pressing structure, are prone to localized wear, deformation, or even jamming when bone fragments, hard bone debris, or other hard foreign objects adhere to the conveyor belt surface.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-layer stacked conveying device for food conveying, comprising a hollow frame one, a hollow frame two disposed on the lower side of the hollow frame one, and a hollow frame three disposed on the lower side of the hollow frame two. Connecting plates are installed on the outer walls of the hollow frames one, two, and three. A motor is installed on the upper surface of the hollow frame one, and a transmission roller is fixedly mounted on the output end of the motor via a reduction gearbox. A conveyor belt is disposed on the outer wall of the transmission roller, and a cleaning mechanism is disposed on the lower surface of the conveyor belt. A rotating roller and a support frame are disposed on the inner wall of the conveyor belt. A collection frame and a hollow plate are installed on the lower surfaces of the hollow frames one on both sides. Discharge pipes are installed inside the collection frames and hollow plates. Fixed plates are installed on the upper surfaces of the hollow frames two and three, and a flipping mechanism is disposed inside the fixed plates.

[0007] The above scheme uses a motor as the active power source for the conveying device. The output end is connected to the transmission roller via a gearbox, driving the conveyor belt to run. Food materials are placed on the upper side of the conveyor belt and transported from the inlet to the outlet. The materials are transferred and transported through the upper, middle and lower arrangement of hollow frames one, two and three, so as to realize multi-layer superimposed conveying of food materials. Since the conveyed material is meat, it inevitably contains blood, oil or meat scraps. The cleaning mechanism on the lower side of the conveyor belt cleans the attached materials. The cleaned attached materials are collected by the hollow plate, and the blood dripping from the conveyor belt during operation is collected by the collection box on the lower side of the conveyor belt.

[0008] Preferably, the cleaning mechanism includes a scraper, the upper surface of which is disposed on the lower surface of the conveyor belt. A rotating shaft is installed on both outer walls of the scraper. The outer wall of the rotating shaft is rotatably connected to the inside of the hollow frame.

[0009] Preferably, a gear is installed on the outer wall of the rotating shaft, and a toothed plate is meshed with the tooth end of the gear. The outer wall of the toothed plate is slidably connected to the interior of the hollow frame. A trapezoidal block is installed on the outer wall of the toothed plate, and an inclined plate is provided on the outer wall of the trapezoidal block. A scraper is installed on the outer wall of the inclined plate, and the scraper is located on the lower side of the conveyor belt.

[0010] Preferably, the outer wall of the inclined plate is slidably connected to the interior of the hollow frame, and a ball bearing is provided inside the inclined plate, with the outer wall of the ball bearing disposed on the outer wall of the trapezoidal block.

[0011] Preferably, the hollow frames one, two, and three are symmetrically arranged, the outer walls of the transmission roller and the rotating roller are rotatably connected to the inside of the hollow frame one, the outer wall of the support frame is installed on the outer wall of the hollow frame one, and a fan is installed on the upper surface of the hollow frame one.

[0012] Preferably, the flipping mechanism includes a torsion spring, one end of which is installed inside the fixed plate, and the other end of which is installed with a support frame. A support rod is rotatably connected inside the support frame, and both ends of the support rod are installed inside the fixed plate. One end of a telescopic rod is provided on the lower surface of the support frame, and the other end of the telescopic rod is provided on the outer wall of the fixed plate.

[0013] Preferably, a through-hole plate is installed inside the support frame, and a flexible hose is connected inside the support frame. The side of the flexible hose away from the support frame passes through the interior of the fixing plate and is connected to a collection box. The outer wall of the collection box is installed on the outer wall of the fixing plate.

[0014] Preferably, a slide rod is slidably connected inside the support frame, and a buffer frame is installed on the side of the slide rod away from the support frame. The outer wall of the buffer frame is set on the inner wall of the support frame, and one end of a helical spring is installed on the side of the buffer frame close to the support frame. The other end of the helical spring is installed on the inner wall of the support frame.

[0015] Preferably, the outer wall of the support rod is wrapped with a rope, and the side of the rope away from the support rod passes through the interior of the load-bearing frame and is fitted with a baffle. The outer wall of the baffle is slidably connected to the interior of the load-bearing frame.

[0016] Preferably, one end of the baffle is fitted with an elastic element, and the other end of the elastic element is fitted inside the support frame.

[0017] This invention provides a multi-layer stacked conveying device for food conveying. It has the following beneficial effects: 1. In this invention, when chicken is transported via a conveyor belt, the conveyor belt inevitably carries blood, grease, or meat scraps. The first scraper cleans the surface of the conveyor belt in real time to ensure its cleanliness and reduce secondary contamination of subsequent transported chicken. When bone fragments or other hard objects adhere to the conveyor belt surface, the first scraper rotates to avoid them. Through the cooperation of gears, toothed plates, trapezoidal blocks, inclined plates, and ball bearings, the inclined scraper moves upward, applying lateral force to the bone fragments or other hard objects, causing them to detach from the conveyor belt surface and be scraped off. This prevents bone fragments from remaining on the conveyor belt surface for extended periods, causing scratches, chicken damage from compression, and jamming during subsequent interlayer transport, while also improving the service life of the conveyor belt.

[0018] 2. In this invention, when chicken meat is conveyed into the inner side of the carrying frame, the flexible buffer frame and the spiral spring absorb the impact force when the chicken meat enters the carrying frame. The sliding rod can limit the movement of the buffer frame to avoid damaging the chicken meat. After the inner side of the carrying frame carries a certain weight of chicken meat, the resulting gravity causes the entire carrying frame to rotate on the outer wall of the support rod, deforming the torsion spring and retracting the telescopic rod. After the carrying frame rotates to a suitable angle, the chicken meat is conveyed to the lower conveyor belt under its own gravity. At the same time, as the amount of chicken meat decreases, the buffer frame assists in the downward conveying of the chicken meat, reducing the problems of rolling, squeezing, sticking and jamming caused by free fall during the interlayer transfer of chicken meat, thus improving the integrity of chicken meat conveying.

[0019] 3. When the chicken is carried inside the support frame, the chicken's own blood or other moisture flows into the interior of the support frame through the perforated plate. The interior of the support frame has grooves to facilitate the flow of blood into the collection box through a hose. With the cooperation of ropes, baffles, and elastic elements, the baffles move automatically when the support frame rotates, blocking the through holes of the perforated plate. This prevents residual blood that has not been completely drained from the support frame from flowing back to the surface of the chicken when the support frame is tilted. This prevents the chicken from being contaminated again during interlayer transfer, reduces conveyor belt contamination caused by blood dripping, wetness on the surface of the chicken, and subsequent hygiene risks.

Detailed Implementation

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 - Appendix Figure 6 This invention provides a multi-layer stacked conveying device for food conveying, including a hollow frame 1, a hollow frame 2 on the lower side of the hollow frame 1, and a hollow frame 3 on the lower side of the hollow frame 2. Connecting plates 22 are installed on the outer walls of the hollow frames 1, 2, and 3. A motor 4 is installed on the upper surface of the hollow frame 1. A transmission roller 5 is fixedly installed at the output end of the motor 4 via a reduction gearbox. A conveyor belt 6 is installed on the outer wall of the transmission roller 5. A cleaning mechanism 14 is installed on the lower surface of the conveyor belt 6. A rotating roller 7 and a support frame 8 are installed on the inner wall of the conveyor belt 6. A collection frame 10 and a hollow plate 11 are installed on the lower surfaces of the two hollow frames 1. A discharge pipe 21 is installed inside the collection frame 10 and the hollow plate 11. A fixing plate 12 is installed on the upper surfaces of the hollow frames 2 and 3. A flipping mechanism 13 is installed inside the fixing plate 12.

[0024] Specifically, the outer walls of hollow frames 1, 2, and 3 are assembled and fixed via connecting plates 22. The vertical spacing between hollow frames 1, 2, and 3 can be adjusted as needed. The lowest hollow frame 3 is equipped with support legs to support the entire conveying device. The conveying components of hollow frames 2 and 3 are identical to those of hollow frame 1, so further details are omitted. Through the gearbox of motor 4, appropriate rotation is applied to the drive roller 5, causing the conveyor belt 6 to convey at a suitable rhythm. Since chicken or other meat products inevitably contain blood, grease, or meat scraps, the conveyor belt 6 is subjected to [unspecified process / conditioning]. The collection box 10 collects the impurities dripping from the conveyor belt 6. The cleaning mechanism 14 scrapes off the deposits on the surface of the conveyor belt 6, thus achieving real-time cleaning of the conveyor belt 6. When there are bone fragments or other hard objects attached to the surface of the conveyor belt 6, the scraping component of the cleaning mechanism 14 can avoid the center and perform secondary scraping, so that the bone fragments or other hard objects are detached from the surface of the conveyor belt 6 and scraped off after being subjected to lateral force. The flipping mechanism 13 prevents the material from falling vertically directly to the lower conveyor belt 6 when conveying from the upper level to the lower level, or from sliding down the inclined straight plate to the lower level, and the impurities attached to the material also slide down to the lower level.

[0025] Please see the appendix Figure 3 - Appendix Figure 5 The cleaning mechanism 14 includes a scraper 142, the upper surface of which is disposed on the lower surface of the conveyor belt 6. A rotating shaft 141 is installed on both outer walls of the scraper 142. The outer wall of the rotating shaft 141 is rotatably connected to the inside of the hollow frame 1. One end of a torsion spring 143 is installed on the outer wall of the rotating shaft 141, and the other end of the torsion spring 143 is installed inside the hollow frame 1.

[0026] Specifically, the flat end of scraper 142 contacts the conveyor belt 6 to scrape away blood, grease, or meat scraps adhering to the outer wall of the conveyor belt 6. The elasticity of torsion spring 143 ensures that the flat end of scraper 142 is in continuous contact with the outer wall of the conveyor belt 6 under normal conditions. Only when scraper 142 cannot remove hard objects or bone fragments is scraped away by rotating shaft 141. The rotation of shaft 141 is supported by the interior of the hollow frames 1 on both sides.

[0027] Please see the appendix Figure 3 - Appendix Figure 5 A gear 144 is installed on the outer wall of the rotating shaft 141. The tooth ends of the gear 144 are meshed with a toothed plate 145. The outer wall of the toothed plate 145 is slidably connected to the inside of the hollow frame 1. A trapezoidal block 146 is installed on the outer wall of the toothed plate 145. An inclined plate 147 is provided on the outer wall of the trapezoidal block 146. A scraper 148 is installed on the outer wall of the inclined plate 147. The scraper 148 is located on the lower side of the conveyor belt 6.

[0028] Specifically, the rotation of the shaft 141 is converted into the lateral movement of the trapezoidal block 146 through the cooperation of the gear 144 and the toothed plate 145. The movement of the toothed plate 145 is supported and restricted by the support block inside the hollow frame 1. The trapezoidal block 146 and the inclined plate 147 are matched to facilitate the conversion of the lateral movement of the trapezoidal block 146 into the vertical movement of the inclined plate 147. The blade of the scraper 148 is set at an angle to ensure that the scraper 148 contacts the conveyor belt 6 at a cut angle after moving upward, and performs secondary cleaning of objects that cannot be cleaned by the flat edge of the scraper 142. Furthermore, the inclination of the scraper 148 can better remove objects attached to the conveyor belt 6.

[0029] Please see the appendix Figure 3 - Appendix Figure 5 The outer wall of the inclined plate 147 is slidably connected to the inside of the hollow frame 1. The inside of the inclined plate 147 is provided with a ball bearing 149, and the outer wall of the ball bearing 149 is provided on the outer wall of the trapezoidal block 146.

[0030] Specifically, the movement of the inclined plate 147 is offset and restricted by the interior of the hollow frame 1 to ensure that the inclined plate 147 and its connecting structure can move vertically up and down. The ball bearings 149 reduce the frictional resistance between the inclined plate 147 and the trapezoidal block 146, allowing the trapezoidal block 146 to smoothly push the inclined plate 147 upward. After the trapezoidal block 146 is reset, the inclined plate 147 and its connecting structure are also reset by their own gravity.

[0031] Please see the appendix Figure 1 - Appendix Figure 2 Hollow frames 1, 2, and 3 are symmetrically arranged. The outer walls of the transmission roller 5 and the rotating roller 7 are rotatably connected to the inside of hollow frame 1. The outer wall of the support frame 8 is installed on the outer wall of hollow frame 1. A fan 9 is installed on the upper surface of hollow frame 1.

[0032] Specifically, the hollow frames 1, 2, and 3 are symmetrically arranged to facilitate support for the components in the middle. The hollow frames 1, 2, and 3 are arranged in ascending order from top to bottom to allow for the installation of a flipping component in either the hollow frame 2 or the hollow frame 3. This allows the uppermost conveying component to transport the chicken to the lower side via the flipping component. The rotation of the drive roller 5 and the rotating roller 7 is supported by the interior of the hollow frames 1 on both sides. Fans 9 can be selectively installed on the upper side of the hollow frames 1, 2, and 3 to air-cool the conveyed chicken.

[0033] Please see the appendix Figure 6 - Appendix Figure 9 The flipping mechanism 13 includes a torsion spring 131. One end of the torsion spring 131 is installed inside the fixed plate 12, and the other end of the torsion spring 131 is installed with a bearing frame 133. A support rod 132 is rotatably connected inside the bearing frame 133. Both ends of the support rod 132 are installed inside the fixed plate 12. One end of a telescopic rod 134 is provided on the lower surface of the bearing frame 133, and the other end of the telescopic rod 134 is provided on the outer wall of the fixed plate 12.

[0034] Specifically, the torsion spring 131 provides a restoring force to the carrier frame 133 after rotation, and guides the carrier frame 133 to rotate during the restoring process. The telescopic rod 134, with its internal elastic component, provides support to the carrier frame 133 under normal conditions. When the carrier frame 133 carries chicken and rotates for conveying, it absorbs the weight of the chicken and contracts. When the carrier frame 133 shrinks to a suitable size, it provides an upward thrust to the carrier frame 133. Figure 8 It can be seen that both ends of the telescopic rod 134 are connected to the fixed plate 12 and the bearing frame 133 respectively through rotating components, so that the telescopic rod 134 can rotate adaptively as the bearing frame 133 rotates.

[0035] Please see the appendix Figure 6 - Appendix Figure 10 The inside of the support frame 133 is equipped with a through plate 135, and the inside of the support frame 133 is connected to a hose 136. The side of the hose 136 away from the support frame 133 passes through the inside of the fixing plate 12 and is connected to a collection box 137. The outer wall of the collection box 137 is installed on the outer wall of the fixing plate 12.

[0036] Specifically, by Figure 10 It is known that the through-hole plate 135 has through holes inside, so that the chicken meat on the upper side of the through-hole plate 135 can flow blood into the interior of the support frame 133 instead of accumulating on the surface of the support frame 133. The bottom of the support frame 133 has an inverted conical groove that communicates with the hose 136, so that the blood collected inside the support frame 133 can be transported to the interior of the collection box 137. Since the position of the support frame 133 is higher than that of the collection box 137, the blood flows into the interior of the collection box 137 through the hose 136 by its own gravity. The hose 136 is flexible, so it can adapt to the rotation of the support frame 133 and avoid damage to the hose 136.

[0037] Please see the appendix Figure 7 A slide rod 15 is slidably connected inside the support frame 133. A buffer frame 16 is installed on the side of the slide rod 15 away from the support frame 133. The outer wall of the buffer frame 16 is set on the inner wall of the support frame 133. One end of a coil spring 17 is installed on the side of the buffer frame 16 close to the support frame 133. The other end of the coil spring 17 is installed on the inner wall of the support frame 133.

[0038] Specifically, the movement of the slide bar 15 is offset and limited by the interior of the support frame 133. The buffer frame 16 is located on the inner wall of the support frame 133, thereby offsetting and limiting the movement of the buffer frame 16. The buffer frame 16 is U-shaped and has an inner cover to prevent chicken from accumulating on the inner wall of the buffer frame 16 and affecting its movement. The buffer frame 16 is made of flexible material to absorb the impact force of the chicken to prevent the chicken from colliding with hard parts and causing damage. The elasticity of the coil spring 17 can absorb the movement force of the buffer frame 16 and can also reset the movement of the buffer frame 16.

[0039] Please see the appendix Figure 9 - Appendix Figure 10 The outer wall of the support rod 132 is wrapped with a rope 18. The side of the rope 18 away from the support rod 132 passes through the interior of the bearing frame 133 and is fitted with a baffle 19. The outer wall of the baffle 19 is slidably connected to the interior of the bearing frame 133. One end of the elastic element 20 is installed on the outer wall of the baffle 19, and the other end of the elastic element 20 is installed inside the bearing frame 133.

[0040] Specifically, one end of the rope 18 is fixed to the support rod 132, and the other end of the rope 18 passes through the interior of the bearing frame 133 and is fixed to the baffle 19. The baffle 19 can slide inside the bearing frame 133 so that when the bearing frame 133 rotates, the rope 18 is wound around the outer wall of the support rod 132 due to the fixed length of the rope 18. This causes the baffle 19 to move. Since the baffle 19 is located between the through-hole plate 135 and the bearing frame 133, it can block or release the through hole of the through-hole plate 135 when the baffle 19 moves. The elastic force of the elastic element 20 can help the baffle 19 to reset after moving.

[0041] Workflow: First, chicken or other meat products are placed on the uppermost conveyor belt 6. The motor 4, mounted on the hollow frame 1, drives the transmission roller 5 to rotate at a suitable speed through the reduction gearbox, causing the conveyor belt 6 and the rotating roller 7 to rotate. The upper side of the conveyor belt 6 is supported by the support frame 8, thus supporting the conveying of the chicken. During the conveying process, the chicken can be cooled to a certain extent by the fan 9 to prevent blood from remaining on the conveyor belt 6. The chicken itself contains blood, grease, or meat scraps, which can be cleaned by the cleaning mechanism 14 below to prevent the attachments from sticking to the conveyor belt 6 and causing clumping or solidification. After the chicken is conveyed from the inlet end of the upper conveyor belt 6 to the outlet end, the discharging mechanism 13 transfers the discharged chicken to the next layer of conveyor belt 6 for multi-layer stacking and conveying of chicken. The same process applies to subsequent layers.

[0042] Under normal conditions, scraper 142 continuously contacts the outer wall of conveyor belt 6 to clean the adhering substances on the outer wall of conveyor belt 6. Blood dripping from conveyor belt 6 is collected by collection frame 10. Blood, grease, or meat scraps adhering to the outer wall of conveyor belt 6 are scraped off by scraper 142 and collected by hollow plate 11. When hard objects, such as bone fragments, adhere to the outer wall of conveyor belt 6, scraper 142 rotates inside hollow frame 11 via shaft 141, deforming torsion spring 143, allowing scraper 142 to be pushed by the hard object. The rotating shaft 141 rotates downwards to avoid hard objects. When the shaft 141 rotates, the gear 144 causes the toothed plate 145 and the trapezoidal block 146 to move towards the scraper 142. The inclined surface of the trapezoidal block 146 pushes the inclined plate 147 upwards under the limit inside the hollow frame 1, thereby causing the scraper 148 to move upwards to scrape off the hard objects. Since the scraper 148 is in an inclined state, it pushes the hard objects at an angle, causing the hard objects to fall into the hollow plate 11 for collection, so as not to affect the subsequent conveying of chicken.

[0043] After the chicken meat is conveyed from the inlet end of the conveyor belt 6 to the outlet end, it passes through the inclined block set in the bearing frame 133 and enters the inner side of the bearing frame 133. The flexible buffer frame 16 and the helical spring 17 absorb the impact force when the chicken meat enters the bearing frame 133. The sliding rod 15 limits the movement of the buffer frame 16 to prevent damage to the chicken meat. After the bearing frame 133 carries a certain weight of chicken meat, the resulting gravity causes the entire bearing frame 133 to rotate on the outer wall of the support rod 132, deforming the torsion spring 131 and retracting the telescopic rod 134. 3. After rotating to the appropriate angle, the chicken meat is conveyed onto the lower conveyor belt 6 under its own weight. At the same time, as the amount of chicken meat decreases, the buffer frame 16 is reset by the helical spring 17, which assists in pushing the movement of the chicken meat. After the chicken meat is conveyed, the internal weight of the carrying frame 133 decreases. The elastic component inside the telescopic rod 134 provides an upward force for the reset of the carrying frame 133, while the torsion spring 131 provides a rotational force for the carrying frame 133, thereby causing the carrying frame 133 to rotate upward and reset as a whole. The above reset operations are all performed slowly to avoid the carrying frame 133 from overshooting and rotating in the opposite direction.

[0044] When chicken meat is carried inside the support frame 133, the chicken's own blood or other moisture flows into the interior of the support frame 133 through the through-hole plate 135. The interior of the support frame 133 has a groove, which is inverted conical in shape, to facilitate the flow of blood and moisture from inside the support frame 133 into the collection box 137 via the hose 136, thereby collecting the blood and moisture inside the support frame 133. When the support frame 133 rotates and is conveyed, one end of the rope 18 is wrapped around the outer wall of the support rod 132 and remains stationary. As the carrier frame 133 rotates, the rope 18 continues to wind, thereby pulling the baffle 19 to block the through hole of the through-hole plate 135. At this time, the elastic element 20 deforms to prevent the blood inside the carrier frame 133 from flowing out through the through-hole plate 135 when the carrier frame 133 rotates to the lower side, thus contaminating the conveyor belt 6 below. When the carrier frame 133 resets, the elastic force of the elastic element 20 is used to reset the baffle 19 to avoid blocking the through hole of the through-hole plate 135 and affecting the collection of blood in the carrier frame 133 during loading.
