Abstract
Description
Technical Field
[0001] This invention relates to the field of conveying equipment technology, and more specifically to a multifunctional rotary conveying device. Background Technology
[0002] When conveyor belts are idle, they need to be cleaned before placement to prevent the surface material adhering to the conveyor belt from becoming moldy and deteriorating. Currently, cleaning conveyor belts requires manual brushing, followed by rinsing with water and air drying. There is no sterilization process. Manual cleaning is labor-intensive, time-consuming, and inefficient. It also lacks effective sterilization and disinfection of the conveyor belt. After being left for a period of time, bacteria will continue to multiply. Therefore, it is necessary to disinfect and sterilize the conveyor belt after cleaning.
[0003] To address the aforementioned issues, a food sterilization conveying device has emerged on the market. This device includes a conveyor frame containing a conveyor belt, a cleaning mechanism, and a sterilization mechanism. In operation, the conveyor belt is activated, and with the assistance of the cleaning mechanism's spray nozzles, the cleaning mechanism washes away any remaining dough pieces from the conveyor belt. Subsequently, the sterilization mechanism sterilizes and disinfects the conveyor belt, ensuring the quality of subsequent dough conveying.
[0004] The above-mentioned device has the following problems in actual use: when the nozzle sprays water to clean the conveyor belt, the water inlet pipe diameter of the nozzle remains unchanged, which reduces the flexibility of water flow and pressure adjustment, thereby affecting the rinsing efficiency and energy consumption. Summary of the Invention
[0005] This invention provides a multifunctional rotary conveying device to solve the problem of poor flexibility in the flow rate and pressure of water from the nozzle when the existing conveying device sprays water.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional rotary conveying device, comprising a base frame, a conveyor belt, a placement box with a bottom opening, a sterilizing lamp fixed inside the placement box, and a processing mechanism; the conveyor belt is connected to the base frame; the placement box is fixed to the base frame; the processing mechanism includes a conduit, a ring pipe, several guide holes on the conduit, a ring hole on the ring pipe, a top hole on the placement box, and processing components symmetrically arranged on both sides of the conduit; the conduit is connected to the placement box, and the conduit communicates with the top hole; the ring pipe is sleeved on the conduit, and the ring hole communicates with the guide holes; the processing components include a through pipe, a processing pipe, a main pipe, and processing components symmetrically arranged on the main pipe. The system includes processing sections on both sides of the main pipe, auxiliary sections on both sides of the main pipe, and a main hole on the processing pipe. Both ends of the main pipe are connected to the annular pipe and the processing pipe, respectively. The processing pipe is fixedly connected to the placement box. The main pipe is connected to the main hole and communicates with it. Each processing section includes branch pipes and branch holes on the processing pipe. The branch pipes are connected to and communicate with the branch holes. Each auxiliary section includes an auxiliary block and a power unit for driving the auxiliary block to perform intermittent reciprocating motion along the length of the processing pipe. The auxiliary block is slidably connected to the inner wall of the processing pipe and is in contact with the inlet of the branch pipe. The inlet of the main pipe is located on the movement trajectory of the auxiliary block. The outlets of both the main pipe and the branch pipes face the conveyor belt.
[0007] The principles and advantages of this scheme are: When it is necessary to sterilize and disinfect the conveyor belt, start the conveyor belt first, then introduce the disinfectant into the conduit, so that the disinfectant flows through the ring pipe, treatment pipe, etc., and finally is discharged through the main pipe and branch pipes and acts on the conveyor belt.
[0008] During the disinfectant flushing of the conveyor belt, auxiliary blocks intermittently reciprocate within the treatment pipe. Initially, the auxiliary blocks seal the inlet portion of the branch pipe, reducing flow resistance and allowing more disinfectant to preferentially enter the main pipe for primary flushing. Subsequently, the auxiliary blocks move, gradually opening the branch pipe passages and guiding the disinfectant flow, forming alternating pulsed discharge. When the two auxiliary blocks finally move to the main pipe inlet and seal most of the main pipe's inlet diameter, the liquid is forced to divert to the branch pipe for discharge, achieving reverse flushing. Therefore, this periodic switching creates a bidirectional alternating pulsed flow field on the conveyor belt surface, effectively breaking the water boundary layer and improving the removal efficiency and sterilization effect on stubborn stains.
[0009] The movement of the auxiliary blocks forms a dynamic diversion mechanism. This dynamic diversion mechanism controls the drainage priority of the main pipe and the branch pipes in sequence, so that the rinsing flow field alternates and changes direction and intensity on the conveyor belt, effectively improving the uniformity of disinfectant coverage, enhancing the ability to peel off residues, and avoiding cleaning dead corners.
[0010] The purpose of installing germicidal lamps is to further disinfect the conveyor belt, thereby reducing bacterial residue on the conveyor belt more effectively.
[0011] Furthermore, the auxiliary block has several auxiliary holes.
[0012] The auxiliary hole is designed to prevent the main pipe from being completely closed without it, which could lead to a localized vacuum or a sudden pressure surge, when the auxiliary block moves to fully fit the main pipe inlet and seals most of its diameter. The auxiliary hole maintains a small flow channel, ensuring that liquid can still pass slowly through the system, maintaining hydraulic continuity, preventing air lock or water hammer, and improving operational stability.
[0013] Secondly, in the final stage before the auxiliary block completely seals the main pipe, the auxiliary hole can guide a small amount of liquid to continuously pulsate out from the main pipe side, forming a multi-stage cleaning rhythm of "main flushing → weak maintenance → reverse flushing". This fine control improves the penetration and removal time of the liquid flow on the stains, enhances the cleaning depth, and, in conjunction with the opening process of the branch pipes, achieves more delicate spatial coverage.
[0014] Finally, as the auxiliary block gradually covers the branch pipe inlet, the auxiliary hole can act as a pilot drain, causing the branch pipe flow rate to decrease gradually rather than be abruptly cut off. This soft switching mechanism effectively smooths the flow transfer process between the main pipe and the branch pipes, making the changes in flushing intensity gentler and reducing impact damage to the conveyor belt surface.
[0015] Furthermore, the treatment unit also includes a linkage block; a side block is fixedly connected to the linkage block; the side block is fixedly connected to the auxiliary block; and the water inlet of the branch pipe is located on the movement trajectory of the linkage block.
[0016] The linkage block is designed to simultaneously seal a portion of the branch pipe inlet while the two auxiliary blocks are engaged with the main pipe inlet, forcing the disinfectant to flow out through the branch pipe. This limits the flow rate of the backwash. This design prevents uncontrolled flushing force caused by a sudden full opening of the branch pipe during the switch from "main pipe-dominated" to "branch pipe-dominated," ensuring orderly alternation between the main and secondary drainage channels and improving the controllability of the flushing rhythm.
[0017] Simultaneously, the linkage block seals part of the diameter of the branch pipe inlet, which is equivalent to introducing a throttling mechanism during the backwashing stage, causing the branch pipe discharge to form a concentrated, high-speed jet, enhancing the impact force on specific areas. At the same time, the main pipe is in a low-flow state due to the blockage of the auxiliary block. Under the combined effect of the two, a composite scouring field with alternating strong and weak currents and changing directions is formed on the surface of the conveyor belt, significantly improving the uniformity of cleaning, the ability to remove dead corners, and the efficiency of disinfection.
[0018] Furthermore, the processing component also includes a control block; the control block is located at the connection between the through pipe and the processing pipe, and the control block is fixedly connected to the linkage block.
[0019] The control block is designed to simultaneously seal the connection between the auxiliary block and the treatment pipe when the auxiliary block is located at the inlet of the branch pipe, limiting the total flow into the treatment pipe and directing the disinfectant solution to the main pipe inlet in the initial stage of the system. At this time, the linkage block has not yet been attached to the branch pipe, and the branch pipe is in an open state. However, because the inlet is partially sealed by the auxiliary block and the total flow is throttled by the control block, the actual diversion is minimal. This stage achieves unidirectional strong flushing of the main pipe, effectively removing the main contaminated areas.
[0020] As the auxiliary block moves toward the main inlet, the control block gradually detaches from the connecting port, increasing the flow area and thus raising the total liquid inflow into the treatment pipe. At this point, the linkage block simultaneously engages with the branch pipe inlet and seals part of its passage, while the main pipe is about to be completely blocked. The gradual opening of the control block, coordinated with the actions of the auxiliary / linkage block, allows the system to smoothly transition from "main pipe-driven" to "branch pipe-driven," avoiding pressure fluctuations caused by sudden flow changes and achieving a shock-free mode switching.
[0021] Furthermore, the processing unit also includes a flow amplification unit; the flow amplification unit includes an inner shaft, a power component for driving the inner shaft to rotate; a branch pipe and a branch hole are rotatably connected; the inner shaft is rotatably connected to the processing pipe, and the inner shaft is fixedly connected to the branch pipe.
[0022] When the branch pipe rotates, its outlet direction also rotates, transforming the originally fixed linear jet into a ring-shaped or spiral scouring belt, effectively covering a wider area of the conveyor belt. Especially when the auxiliary block partially closes the inlet and forms a concentrated flow stream, rotation allows the high-pressure liquid flow to continuously scan along the trajectory, significantly reducing cleaning blind spots.
[0023] During rotation, the impact angle of the water flow on the stain surface continuously changes, avoiding the "adaptive residue" caused by constant rinsing. Combined with the pulse-type flow regulation controlled by the auxiliary block, the rotating pipe can create a combined effect of "high-frequency impact + angle switching" in local areas, more efficiently breaking down highly adhesive pollutants.
[0024] Furthermore, the processing component also includes an adjustment linkage unit; the adjustment linkage unit includes a side block, a round block, and a drive unit for driving the main pipe to rotate intermittently; the main pipe is rotatably connected to the main hole; the side block is fixedly connected to the main pipe; the round block is fixedly connected to the side block, and the round block is in contact with the outlet of the branch pipe; the side wall of the branch pipe has several wall holes circumferentially opened.
[0025] The continuous rotation of the branch pipes allows the wall holes to sweep across the conveyor belt surface, creating a spatial scan. Simultaneously, the circular blocks reciprocate intermittently with the main pipe, intermittently sealing the outlets of the two branch pipes. When the circular blocks seal the outlets, the hydraulic pressure inside the branch pipe increases, forcing the liquid to be pressurized and ejected from the side wall nozzles, forming a high-energy jet array that performs a point-matrix impact peeling of stains, suitable for stubborn residues. When the circular blocks detach from the outlets, disinfectant flows steadily from the main outlet, forming a wide, low-speed wetting flow used to rinse away residue and evenly distribute the disinfectant.
[0026] During the discharge of disinfectant through the branch pipes, a composite cleaning field with alternating "high-frequency micro-spray + steady-state main jet + rotary scanning" triple modes is formed on the surface of the conveyor belt, achieving full coverage of "point-line-surface" and completely eliminating the "striped cleaning" defects of traditional fixed nozzles.
[0027] Furthermore, the processing mechanism also includes a filling and expanding section; the filling and expanding section includes a circular tube, a bottom tube, a filling hole opened on the bottom tube, and a motion unit for driving the conduit to rotate; the conduit is rotatably connected to the placement box; the conduit is connected to the circular tube; the bottom tube is connected to the circular tube; and the filling hole faces the conveyor belt.
[0028] During the discharge of disinfectant through the bottom pipe, a multi-dimensional collaborative rinsing mechanism will be further introduced to the existing "dual-rotation linkage and pulse jet" system, forming a three-dimensional cleaning structure with upper and lower double layers, dynamic and static combination, and main and auxiliary complementarity. That is, under the action of the flow-filling holes, a circular bottom flushing belt will be formed, which will fully cover the surface of the conveyor belt and, in conjunction with the movement of the conveyor belt itself, achieve dynamic disinfection and cleaning of the bottom without dead corners or overlap.
[0029] Furthermore, a first gear is fixedly connected to the main pipe; the power unit is a first rack; the first rack is fixedly connected to the linkage block; and the two first racks mesh with the first gear respectively.
[0030] During the intermittent reciprocating rotation of the main pipe, the first gear rotates synchronously. During the rotation of the first gear, through the meshing of the first gear and the first rack, the first rack can perform intermittent reciprocating motion along the length of the processing pipe.
[0031] Furthermore, the filling and expansion section also includes an auxiliary drive unit; the auxiliary drive unit includes a drive shaft and an auxiliary drive component for driving the drive shaft to rotate; the drive shaft is rotatably connected to the placement box; the power component includes a first bevel gear and a second bevel gear; the first bevel gear is fixedly connected to the inner shaft; the second bevel gear is fixedly connected to the drive shaft; the first bevel gear and the second bevel gear mesh.
[0032] During the rotation of the drive shaft, the drive shaft drives the inner shaft to rotate synchronously through the meshing of the first bevel gear and the second bevel gear.
[0033] Furthermore, the filling and expansion section also includes a first arc-shaped rack and a second arc-shaped rack fixedly connected to both ends of the bottom tube; the motion unit includes a second gear; the second gear is fixedly connected to the main tube; the second gear is located on the motion trajectory of the first arc-shaped rack and the second arc-shaped rack, and the second gear can mesh with the first arc-shaped rack and the second arc-shaped rack respectively.
[0034] During the rotation of the bottom tube, the first and second arc-shaped racks move synchronously. When the first arc-shaped rack meshes with the second gear, the second gear rotates forward; subsequently, when the second arc-shaped rack meshes with the second gear, the second gear rotates in reverse. Therefore, through the mutual cooperation of the first and second arc-shaped racks, the second gear can drive the main tube to perform intermittent reciprocating motion. Attached Figure Description

[0053] The motion unit includes a motor 30, a rotating shaft, a third gear 31, and a first ring rack 32; the motor 30 is fixedly connected to the top of the placement box 3; the rotating shaft is rotatably connected to the placement box 3 and fixedly connected to the output shaft of the motor 30; the third gear 31 is fixedly connected to the rotating shaft; the first ring rack 32 is fixedly connected to the guide tube 4; the third gear 31 meshes with the first ring rack 32.
[0054] It also includes a second annular rack 33 fixedly connected to the conduit 4; the auxiliary drive component is a fourth gear 34; the fourth gear 34 is fixedly connected to the drive shaft 24; the fourth gear 34 meshes with the second annular rack 33.
[0055] Specific implementation process: When it is necessary to sterilize and disinfect the conveyor belt 2, start the conveyor belt 2 first, and then introduce the disinfectant into the conduit 4, so that the disinfectant flows through the ring pipe 5, the treatment pipe 8, etc., and finally is discharged through the main pipe 9 and the branch pipe 10 and acts on the conveyor belt 2.
[0056] During the introduction of disinfectant, motor 30 is started, which in turn drives the rotating shaft to rotate via the output shaft of motor 30. During the rotation of the rotating shaft, the shaft meshes with the first annular rack 32 through the third gear 31, thereby driving the conduit 4 to rotate. During the rotation of the conduit 4, the conduit 4 drives the bottom tube 21 to rotate synchronously. During the rotation of the bottom tube 21, the first arc-shaped rack 27 and the second arc-shaped rack 28 move synchronously. When the first arc-shaped rack 27 meshes with the second gear 29, the second gear 29 rotates forward; subsequently, when the second arc-shaped rack 28 meshes with the second gear 29, the second gear 29 rotates in reverse. Therefore, through the mutual cooperation of the first arc-shaped rack 27 and the second arc-shaped rack 28, the second gear 29 can drive the main tube 9 to perform intermittent reciprocating motion.
[0057] During the intermittent reciprocating rotation of the main pipe 9, the first gear 22 rotates synchronously. During the rotation of the first gear 22, through the meshing of the first gear 22 and the first rack 23, the first rack 23 can perform intermittent reciprocating motion along the length direction of the processing pipe 8. During the movement of the first rack 23, the first rack 23 drives the auxiliary block 11 to move synchronously through the linkage block 13.
[0058] Therefore, during the disinfectant flushing of conveyor belt 2, auxiliary blocks 11 intermittently reciprocate within treatment pipe 8. Initially, auxiliary blocks 11 seal part of the inlet of branch pipe 10, reducing flow resistance and allowing more disinfectant to preferentially enter main pipe 9 for primary flushing. Subsequently, auxiliary blocks 11 move, gradually opening the passage of branch pipe 10 and guiding the disinfectant to flow separately, forming alternating pulsed discharge. When the two auxiliary blocks 11 finally move to the inlet of main pipe 9 and seal most of the inlet diameter, the liquid is forced to turn towards branch pipe 10 for discharge, achieving reverse flushing. Thus, this periodic switching forms a bidirectional alternating pulsed flow field on the surface of conveyor belt 2, effectively breaking the water flow boundary layer and improving the removal efficiency and sterilization effect on stubborn stains.
[0059] The movement of the auxiliary block 11 forms a dynamic diversion mechanism. This dynamic diversion mechanism controls the drainage priority of the main pipe 9 and the branch pipe 10 in a time sequence, so that the rinsing flow field alternately changes direction and intensity on the conveyor belt 2, effectively improving the uniformity of disinfectant coverage, enhancing the ability to peel off residues, and avoiding cleaning dead corners.
[0060] During the movement of the auxiliary block 11, the auxiliary hole 12 is provided so that when the auxiliary block 11 moves to fully fit the inlet of the main pipe 9 and seal most of its diameter, without the auxiliary hole 12, the main pipe 9 would be almost completely closed, which could easily cause a local vacuum or a sudden pressure rise. The presence of the auxiliary hole 12 can retain a small flow channel, ensuring that the liquid in the system can still pass through slowly, maintaining hydraulic continuity, preventing air lock or water hammer, and improving operational stability.
[0061] Secondly, in the final stage before the auxiliary block 11 completely seals the main pipe 9, the auxiliary hole 12 can guide a small amount of liquid to continuously pulsate out from the side of the main pipe 9, forming a multi-stage cleaning rhythm of "main flushing → weak maintenance → reverse flushing". This fine control improves the penetration and removal time of the liquid flow on the stains, enhances the cleaning depth, and, in conjunction with the opening process of the branch pipe 10, achieves more delicate spatial coverage.
[0062] Finally, as the auxiliary block 11 gradually covers the inlet of the branch pipe 10, the auxiliary hole 12 can act as a pilot drain, causing the flow rate of the branch pipe 10 to decrease gradually rather than be cut off rapidly. This soft switching mechanism effectively smooths the flow transfer process between the main pipe 9 and the branch pipe 10, making the change in flushing intensity gentler and reducing impact damage to the surface of the conveyor belt 2.
[0063] During the synchronized movement of the linkage block 13 and the auxiliary block 11, the linkage block 13 is designed to simultaneously adhere to the inlet of the branch pipe 10 and seal a portion of its diameter when the two auxiliary blocks 11 are engaged with the inlet of the main pipe 9 and the disinfectant is forced to flow out through the branch pipe 10, thus limiting the flow intensity of the backwash. This design prevents the flushing force from becoming uncontrollable due to the sudden full opening of the branch pipe 10 during the switching process from "main pipe 9 dominance → branch pipe 10 dominance," achieving an orderly alternation between the main and secondary drainage channels and improving the controllability of the flushing rhythm.
[0064] Simultaneously, the linkage block 13 seals part of the inlet diameter of the branch pipe 10, which is equivalent to introducing a throttling mechanism during the backwashing stage, causing the liquid discharged from the branch pipe 10 to form a concentrated, high-speed jet, enhancing the impact force on specific areas. At the same time, the main pipe 9 is in a low-flow state due to the blockage of the auxiliary block 11. Under the combined effect of the two, a composite scouring field with alternating strong and weak currents and changing directions is formed on the surface of the conveyor belt 2, which significantly improves the uniformity of cleaning, the ability to remove dead corners, and the efficiency of disinfection.
[0065] During the movement of the linkage block 13, the linkage block 13 drives the control block 15 to move synchronously. The control block 15 is designed to simultaneously seal the connection between the auxiliary block 11 and the treatment pipe 8 when the auxiliary block 11 is located at the inlet of the branch pipe 10, limiting the total flow into the treatment pipe 8 and directing the disinfectant solution to the inlet of the main pipe 9 in the initial stage of the system. At this time, the linkage block 13 has not yet come into contact with the branch pipe 10, and the branch pipe 10 is in an open state. However, because the inlet is partially sealed by the auxiliary block 11 and the total flow is throttled by the control block 15, the actual diversion is minimal. This stage achieves unidirectional strong flushing of the main pipe 9, effectively removing the main contaminated areas.
[0066] As the auxiliary block 11 moves toward the inlet of the main pipe 9, the control block 15 gradually disengages from the connecting port, the flow area gradually increases, and the total liquid inflow into the treatment pipe 8 increases accordingly. At this time, the linkage block 13 simultaneously contacts the inlet of the branch pipe 10 and seals part of its channel, while the main pipe 9 is about to be completely blocked. The gradual opening of the control block 15, in coordination with the actions of the auxiliary block 11 / linkage block 13, allows the system to smoothly transition from "main pipe 9 as the main flow" to "branch pipe 10 as the main flow", avoiding pressure fluctuations caused by sudden changes in flow rate and achieving a shock-free mode switching.
[0067] During the rotation of the conduit 4, the second annular rack 33 rotates synchronously. During this rotation, the second annular rack 33 meshes with the fourth gear 34, which in turn drives the drive shaft 24 to rotate synchronously. During this rotation, the drive shaft 24 meshes with the first bevel gear 25 and the second bevel gear 26, thereby driving the inner shaft 16 to rotate synchronously. During this rotation, the inner shaft 16 drives the branch pipe 10 to rotate synchronously.
[0068] When the branch pipe 10 rotates, its water outlet direction also rotates, transforming the originally fixed linear jet into a ring-shaped or spiral scouring belt, effectively covering a wider area of the conveyor belt 2. Especially when the auxiliary block 11 partially closes the inlet and forms a concentrated flow stream, rotation allows the high-pressure liquid flow to continuously scan along the trajectory, significantly reducing cleaning blind spots.
[0069] During rotation, the impact angle of the water flow on the stain surface continuously changes, avoiding "adaptive residue" caused by constant rinsing. Combined with the pulse-type flow regulation controlled by auxiliary block 11, the rotating branch pipe 10 can create a combined effect of "high-frequency impact + angle switching" in a local area, more efficiently breaking down highly adhesive contaminants. At the same time, the continuous rotation of the branch pipe 10 allows the wall holes 19 to sweep across the surface of the conveyor belt 2, forming a spatial scanning effect. During the intermittent reciprocating rotation of the main pipe 9, the circular block 18 moves synchronously. During the movement of the circular block 18, it can alternately seal the outlets of the two branch pipes 10. Therefore, when the circular block 18 seals the outlet of the branch pipe 10, the hydraulic pressure inside the branch pipe 10 increases, and the liquid is forced to be pressurized and ejected from the side wall nozzles, forming a high-energy jet array to perform a dot matrix impact peeling of stains, which is suitable for stubborn residues. When the circular block 18 leaves the outlet of the branch pipe 10, the disinfectant flows out steadily from the main outlet of the branch pipe 10, thereby forming a wide-range, low-speed wetting flow, which is used to rinse away residues and evenly distribute the disinfectant.
[0070] During the discharge of disinfectant through the branch pipe 10, a composite cleaning field with alternating "high-frequency micro-spray + steady-state main jet + rotary scanning" triple modes will be formed on the surface of the conveyor belt 2, achieving full coverage of "point-line-surface" and completely eliminating the "striped cleaning" defect of traditional fixed nozzles.
[0071] During the rotation of the bottom pipe 21, the filling holes are designed to further introduce a multi-dimensional collaborative rinsing mechanism at the bottom, building upon the existing "dual-rotation linkage and pulse jet" system. This creates a three-dimensional cleaning structure with upper and lower double layers, dynamic and static elements, and primary and secondary components complementing each other. Specifically, the filling holes create a circular bottom flushing belt that fully covers the surface of the conveyor belt 2, and, in conjunction with the movement of the conveyor belt 2 itself, achieves dynamic disinfection and cleaning of the bottom without dead angles or overlap.
[0072] In summary, by using the rotatable conduit 4 as the core hub, and constructing a fluid distribution path with the annular pipe 5, the through pipe 7, and the treatment pipe 8, a three-dimensional cleaning structure of "top double-rotation linkage spray + bottom directional flushing" is formed, which can then carry out comprehensive, thorough, and complete disinfection and cleaning of the conveyor belt 2.
