Description

Technical Field

[0001] This invention belongs to the field of food conveying equipment technology, and specifically relates to a conveying device for the food supply chain. Background Technology

[0002] As a core link in agricultural product processing, fresh produce transportation, and finished product distribution, the food supply chain relies heavily on conveyor systems. These systems are crucial for continuous material transport and are widely used in production lines for various food products, including fresh fruits and vegetables, pre-prepared ingredients, and grain and oil products. With the continuous improvement of hygiene standards in the food industry, supply chain conveyor equipment not only needs to meet the basic requirement of stable conveying but also needs to consider comprehensive performance aspects such as surface cleanliness, impurity separation, aseptic protection, and energy-efficient operation to adapt to the trend of large-scale, standardized, and compliant food production. Currently, most food conveyor systems on the market are based on belt conveyor structures, equipped with basic baffles and frame structures. They can complete the horizontal transport of conventional materials and are widely used in small and medium-sized agricultural and food processing enterprises, providing fundamental support for continuous production in the food supply chain.

[0003] Long-term practical application has revealed that existing food conveying devices still suffer from insufficient adaptability in terms of cleaning protection and energy efficiency. After prolonged contact with fresh food, the conveyor belt surface easily accumulates residues, juices, and impurities. Conventional manual cleaning methods are inefficient and difficult to adapt to continuous production rhythms. Some devices with built-in cleaning functions only use a single spray structure, resulting in incomplete cleaning coverage and difficulty in completely removing stubborn deposits. The lack of efficient separation and automatic slag removal structures for the solid-liquid mixture generated during cleaning easily leads to water pollution and pipeline blockage, increasing equipment maintenance costs. Furthermore, the drying structure and cleaning water circulation are independent, with waste heat generated during drying being directly discharged without secondary utilization. This results in high energy consumption, failing to meet the energy-saving and consumption-reducing production needs of agricultural and food processing enterprises and restricting the overall performance of food supply chain conveying equipment. Summary of the Invention

[0004] In view of the problems raised in the background art above, the object of the present invention is to provide a conveying device for the food supply chain.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A conveying device for a food supply chain includes a frame on which a conveyor belt driven by a conveyor belt motor is mounted. The conveyor belt is a strip conveyor belt and is equipped with baffles. The frame is equipped with a mounting platform, a water tank is placed under the mounting platform, and a cleaning mechanism, a power mechanism, and a drying mechanism are mounted on the upper side of the mounting platform. The cleaning mechanism includes a cleaning box installed on the mounting platform. The bottom output end of the cleaning box is connected to the water tank. An inclined filter plate is installed inside the cleaning box. A horizontal filter plate is integrally connected to the lowest end of the inclined filter plate. A reciprocating screw is rotatably installed in the cleaning box. A push plate is threadedly connected to the reciprocating screw. The edge of the push plate contacts the side wall of the cleaning box and the upper surface of the horizontal filter plate. A first motor is installed at the power end of the reciprocating screw. The rotation of the first motor drives the reciprocating screw to rotate, thereby causing the push plate to reciprocate on the horizontal filter plate. Multiple scraper mechanisms are installed on the upper side of the inclined filter plate. The working end of the scraper mechanism contacts the rotating lower surface of the conveyor belt and is used to scrape off the material adhering to the conveyor belt. The cleaning box is equipped with a drain pipe. The output end of the drain pipe is connected to several spray pipes. The output end of the spray pipes corresponds to the rotating lower surface of the conveyor belt and is used to rinse the material adhering to the conveyor belt. The cleaning box is equipped with a slag discharge box, which has two input ends and one output end. The two input ends of the slag discharge box are respectively connected to both sides of the horizontal filter plate. The power mechanism includes a second motor, a pump impeller, and a fan impeller, all fixedly mounted on the mounting platform. The power end of the pump impeller is connected to a drive pulley, and the power end of the fan impeller is connected to a driven pulley. The drive pulley and the driven pulley are connected by belt drive, and the power end of the drive pulley is connected to the output end of the second motor. The inlet end of the pump impeller compartment is connected to the bottom of the water tank, and the outlet end of the pump impeller compartment is connected to the drain pipe. The drying mechanism includes an air box mounted on the mounting platform. The top of the air box is open and corresponds to the conveyor belt. The output end of the air box is connected to the output end of the fan blade chamber.

[0006] Furthermore, the air box is equipped with heating pipes and a temperature sensor. The addition of heating pipes and a temperature sensor enables controllable adjustment of the drying temperature, adapting to the drying needs of different food conveyor belts, avoiding problems such as incomplete drying at low temperatures and damage to the conveyor belt at high temperatures, and improving drying stability.

[0007] Furthermore, the gas box is connected to a heat exchange gas pipe on its side, which is coiled around the side of the water tank. By coiling the heat exchange gas pipe around the water tank, the waste heat from drying is recovered to preheat the water in the water tank, realizing the secondary utilization of heat energy, reducing equipment energy consumption, and improving the cleaning effect of the rinsing water. The structure is simple and has no additional energy consumption.

[0008] Furthermore, the scraper mechanism is placed on both sides of the nozzle, with at least one group placed on one side of the nozzle. The scraper mechanism is placed on both sides of the nozzle to form a dual cleaning layout of pre-scraping + post-cleaning, which enhances the cleaning effect of impurities on the conveyor belt surface, avoids cleaning dead corners, and improves the overall cleaning effect.

[0009] Further defining the scraper mechanism, it includes a cylinder mounted on the inclined filter plate, a movable block sleeved on the outer side of the top of the cylinder, a spring installed between the top of the cylinder and the movable block, a scraper mounted on the top of the movable block, the scraper being inclined toward the conveyor belt, the working edge of the scraper contacting the scraper, and adopting a spring-elastic floating scraper structure to adaptively conform to the surface of the conveyor belt, ensuring scraping force while avoiding scratching the conveyor belt, adapting to slight deformation of the conveyor belt, and extending the service life of the equipment.

[0010] Furthermore, the frame is equipped with a central control box, which is responsible for scheduling the entire device for adaptive operation. The central control box is configured to uniformly schedule the operation of the equipment, realize the coordinated linkage of cleaning, drying and slag discharge processes, simplify the operation process, and improve the level of automation of the equipment.

[0011] Furthermore, the inclined filter plate and the horizontal filter plate are integrally and smoothly connected, with no splicing gaps, to avoid impurities getting stuck, ensure smooth solid-liquid separation, and reduce the difficulty of cleaning and maintenance.

[0012] Furthermore, the lower edge of the pusher plate is designed as a flat and fitted structure. When the pusher plate moves back and forth, it maintains a gapless fit with the upper surface of the horizontal filter plate. The gapless fit between the pusher plate and the horizontal filter plate thoroughly pushes away impurities from the surface of the filter plate, leaving no residue accumulation, improving the efficiency of automatic slag discharge, and preventing filter plate clogging.

[0013] Furthermore, the upper side of the reciprocating screw is not within the feeding range of the conveyor belt, the position of the reciprocating screw protrudes from the conveyor belt, the material on the conveyor belt does not fall onto the reciprocating screw, the reciprocating screw avoids the feeding range of the conveyor belt, avoids material falling and contaminating the transmission structure, ensures the stability of equipment operation, and reduces the probability of failure.

[0014] Furthermore, the active pulley and the driven pulley can be configured with multiple specifications and ratios, and the pulleys support multiple specifications and ratios, which can flexibly adjust the operating power of the pump and the fan to adapt to different cleaning and drying conditions and improve the adaptability of the equipment.

[0015] The beneficial effects of using the present invention are as follows: This device addresses the problems of incomplete cleaning, inconvenient slag removal, and high energy consumption in food supply chain conveyor equipment. Through the integrated layout of the cleaning mechanism, power mechanism, and drying mechanism, it achieves continuous automatic cleaning of the conveyor belt surface. The elastic scraper, combined with high-pressure spray, completes the thorough removal of impurities and solves the problem of adhering residue. Inclined and horizontal filter plates enable rapid solid-liquid separation, while reciprocating screw linkage pusher plate completes automatic discharge of impurities, avoiding filter plate clogging and water pollution, and reducing equipment maintenance costs; The single motor links the pump and fan to simplify the power structure. At the same time, the heat exchange pipe is used to recover the waste heat from drying and preheat the flushing water, realizing heat energy recovery and utilization and reducing the energy consumption of equipment operation. The overall structure of the machine is adapted to food production hygiene standards, with a high degree of automation. It can stably adapt to the supply chain transportation needs of various food categories such as fruits and vegetables and pre-cooked dishes, thereby improving the overall operating performance and adaptability of the equipment.

[0019] In this embodiment, frame 1 is an integral frame-type load-bearing structure. Conveyor belt motor 2 is fixedly installed at the end of frame 1.

Baffle plates 4 are fixedly installed along the conveying direction of conveyor belt 3 on both sides of conveyor belt 3. Mounting platform 5 is horizontally fixedly connected to the middle cavity of frame 1. Water tank 6 is detachably placed in the lower cavity of mounting platform 5. Cleaning mechanism 7, power mechanism 8, and drying mechanism 9 are sequentially fixedly installed on the upper surface of mounting platform 5 along the rotation path of conveyor belt 3. Cleaning box 71 is fixedly installed on the upper middle part of mounting platform 5, with the bottom of cleaning box 71... A flow port is provided and connected to the internal cavity of the water tank 6. An inclined filter plate 72 is fixedly installed at an angle inside the upper cavity of the cleaning tank 71. A horizontal filter plate 73 is integrally formed and connected to the lowest end of the inclined filter plate 72, and is horizontally arranged inside the cleaning tank 71. A reciprocating screw 74 is supported by bearings on the inner wall of the cleaning tank 71 and is arranged parallel to the horizontal filter plate 73. A push plate 75 is fitted onto the outside of the reciprocating screw 74 via a threaded pair. The side of the push plate 75 slides against the inner wall of the cleaning tank 71, and the bottom edge of the push plate 75 is tightly fitted against the upper surface of the horizontal filter plate 73. A first motor 76 is fixedly installed on the outer wall of the cleaning tank 71. The output shaft of the first motor 76 is connected to the reciprocating screw 74. The shaft end of the multi-screw 74 is coaxially fixedly connected; multiple sets of scraper mechanisms 10 are vertically fixedly installed on the upper surface of the inclined filter plate 72, and the upper end of each set of scraper mechanisms 10 is in contact with the rotating lower surface of the conveyor belt 3; the drain pipe 77 is fixedly installed through the side wall of the cleaning box 71; several spray pipes 78 are equidistantly connected to the output end of the drain pipe 77, and the spraying end of each spray pipe 78 is arranged facing the rotating lower surface of the conveyor belt 3; the slag box 79 is fixedly installed on the outside of the cleaning box 71, and the two sets of input ends of the slag box 79 are respectively connected to the two ends of the horizontal filter plate 73; the second motor 81 is fixedly installed on the upper surface of the mounting platform 5, and the pump impeller chamber 82 and the fan impeller chamber 83 are arranged side by side. The pump impeller 84 is fixedly mounted on the mounting platform 5. The driving pulley 84 is coaxially fixed to the power input shaft of the pump impeller 82, and the driven pulley 85 is coaxially fixed to the power input shaft of the fan impeller 83. The driving pulley 84 and the driven pulley 85 are synchronously driven by the transmission belt. The output shaft of the second motor 81 is coaxially fixedly connected to the driving pulley 84. The water inlet end of the pump impeller 82 is connected to the bottom of the inner cavity of the water tank 6 through the pipeline. The water outlet end of the pump impeller 82 is connected to the input end of the drain pipe 77 through the pipeline. The air box 91 is fixedly mounted on the upper surface of the mounting platform 5. The top opening of the air box 91 faces the rotating lower surface of the conveyor belt 3. The air inlet end of the air box 91 is connected to the air outlet end of the ventilation impeller 83 through the pipeline. The conveyor belt motor 2 drives the conveyor belt 3 to rotate continuously, completing the continuous conveying of food materials. The scraper mechanism 10 continuously adheres to the rotating lower surface of the conveyor belt 3, simultaneously scraping off the residue, juice, and other contaminants adhering to the belt surface. The detached contaminants naturally fall onto the surface of the inclined filter plate 72, while liquid contaminants flow through the pores of the filter plate into the inner cavity of the cleaning box 71 and back to the water tank 6. To further explain, since the transported vegetables have already been washed at the front end, the main function here is to scrape off adhering substances, and there is no problem of the water stains being too turbid after passing through the inclined filter plate 72. Furthermore, it is not difficult for those skilled in the art to understand and implement the installation of a filtration mechanism in the water tank, where solid contaminants automatically slide down the inclined surface of the inclined filter plate 72 onto the surface of the horizontal filter plate 73. The first motor 7 The reciprocating screw 74 is driven to rotate continuously, which drives the push plate 75 to reciprocate linearly along the horizontal filter plate 73, pushing the solid dirt accumulated on the surface of the horizontal filter plate 73 to the slag box 79 for centralized discharge; the second motor 81 synchronously drives the active pulley 84 and the driven pulley 85 to rotate, which drives the pump impeller 82 and the fan impeller 83 to operate synchronously. The pump impeller 82 draws the circulating water in the water tank 6 and delivers it to each spray pipe 78 through the drain pipe 77. The high-pressure water jet washes the rotating lower surface of the conveyor belt 3 to complete deep cleaning. The fan impeller 83 generates high-pressure airflow and delivers it to the air box 91. The airflow is evenly blown onto the cleaned surface of the conveyor belt 3 through the air box 91 to complete the belt surface drying treatment. The cleaned sewage flows back to the water tank 6 to complete the recycling. The machine adopts an integrated layout of scraping, rinsing, solid-liquid separation, automatic slag discharge, and airflow drying. A single power source synchronously drives water circulation cleaning and airflow drying operations. Each process is seamlessly connected without interruption. The structure is compact and the transmission path is simple. The closed-loop water circulation reduces resource consumption. Waste is automatically separated and discharged without manual intervention. The various functional structures work together to form a complete cleaning and conveying system. Unlike conventional layouts with a single cleaning structure, it is suitable for the continuous and hygienic conveying operation requirements of the food supply chain. It is stable in operation and easy to maintain.

[0020] The preferred gas box 91 is equipped with a heating pipe 92 and a temperature sensor 93.

[0021] In this embodiment, the heating pipe 92 is fixedly installed in the internal cavity of the air box 91, and the temperature sensor 93 is fixed on the inner wall of the air box 91 and located in the airflow path. Both the heating pipe 92 and the temperature sensor 93 are connected to the equipment control circuit. The heating power can be adjusted according to different conveyor belt materials and cleaning conditions to meet the drying needs of multiple scenarios, including normal temperature and low temperature. The temperature can be closed-loop regulated by linkage control circuit. Precise control of the drying airflow temperature avoids incomplete drying at low temperatures, leaving water stains, and prevents high-temperature airflow from damaging the conveyor belt surface, thereby improving drying uniformity and equipment stability.

[0022] The preferred gas box 91 is connected to a heat exchange gas pipe 94 on its side, and the heat exchange gas pipe 94 is coiled around the side of the water tank 6.

[0023] In this embodiment, the air inlet of the heat exchange pipe 94 is connected to the air outlet on the side wall of the air box 91. The heat exchange pipe 94 is spirally and tightly wrapped around the outer wall of the water tank 6. The end of the heat exchange pipe 94 is directly connected to the external environment. The number of turns of the heat exchange pipe 94 can be adjusted according to the shape of the water tank 6 to adapt to the preheating requirements of water bodies of different volumes. A one-way valve can be installed to prevent airflow backflow. The waste heat from the recovered dry airflow is used to preheat the water in water tank 6, improving the cleaning and dissolving effect of the rinsing water, realizing the secondary reuse of heat energy, and reducing the overall energy consumption of the equipment.

[0024] Preferably, the scraper mechanism 10 is placed on both sides of the nozzle 78, and at least one part is placed on one side of the nozzle 78.

[0025] In this embodiment, multiple scraper mechanisms 10 are fixed on both sides of the nozzle 78, and at least one scraper mechanism 10 is arranged separately on one side of the conveying path of the nozzle 78. All scraper mechanisms 10 are vertically aligned with the width direction of the conveyor belt 3. The number of scraper mechanisms 10 can be increased or decreased according to the width of the conveyor belt 3, and the spacing of each set of scraper mechanisms 10 can be adjusted to meet the cleaning needs of conveyor belts of different widths. This creates a dual cleaning layout: front-end scraping removes substances, while rear-end cleaning removes water stains, fully covering the surface area of ​​conveyor belt 3, eliminating cleaning dead corners, and enhancing the scraping effect of stubborn dirt.

[0026] The preferred scraper mechanism 10 includes a cylinder 101 mounted on an inclined filter plate 72, a movable block 102 sleeved on the outer side of the top of the cylinder 101, a spring 103 installed between the top of the cylinder 101 and the movable block 102, a scraper 104 mounted on the top of the movable block 102, the scraper 104 being inclined toward the direction of the conveyor belt 3, and the working edge of the scraper 104 contacting the scraper 104.

[0027] In this embodiment, the cylinder 101 is vertically fixed on the upper surface of the inclined filter plate 72, the movable block 102 is movably sleeved on the upper outer wall of the cylinder 101, the spring 103 is sleeved on the outside of the cylinder 101 and its two ends abut against the cylinder 101 and the movable block 102 respectively, and the scraper 104 is inclinedly fixed on the top of the movable block 102 and its edge is attached to the conveyor belt 3. The adhesion pressure of the scraper 104 can be adjusted by replacing the spring 103 with different elastic coefficients, and the scraper 104 can be replaced with different materials to adapt to the cleaning of dirt with different viscosity. The elastic floating structure adapts to the surface deformation of the conveyor belt 3, ensuring scraping force while avoiding scratching the conveyor belt and extending its service life.

[0028] The preferred rack 1 is equipped with a central control box 11, which is responsible for scheduling the entire device for adaptive operation.

[0029] In this implementation case, the central control box 11 is fixedly mounted on the outer wall of the frame 1, and the control lines of the central control box 11 are connected to the conveyor belt motor 2, the first motor 76, the second motor 81 and various detection elements respectively. The expandable communication module enables remote control, and the addition of a touch panel allows for adjustment of equipment operating parameters, adapting to the linkage control needs of automated production lines; Unified scheduling of the start-up, shutdown, and operation rhythm of all mechanisms enables coordinated operation of cleaning, drying, and slag removal processes, simplifies manual operation procedures, and improves the level of equipment automation.

[0030] Preferably, the inclined filter plate 72 and the horizontal filter plate 73 are integrated into a smooth connection structure.

[0031] In this embodiment, the inclined filter plate 72 and the horizontal filter plate 73 adopt an integral stamping structure, and the connection between the two is a smooth arc transition without protruding edges or splicing gaps. The tilt angle of the adjustable inclined filter plate 72 can be adapted to the sliding speed of different dirt, and the surface is treated with anti-stick to reduce the probability of dirt adhesion. To prevent dirt from getting stuck in the joints, ensure smooth solid-liquid separation and dirt sliding off, reduce the frequency of manual cleaning, and lower the difficulty of equipment maintenance.

[0032] Preferably, the lower edge of the push plate 75 is set to a flat and fitted structure, so that the push plate 75 remains in close contact with the upper surface of the horizontal filter plate 73 without gaps when it moves back and forth.

[0033] In this embodiment, the lower edge of the push plate 75 is processed to be flat and fit the end face, and the width of the end face matches the surface width of the horizontal filter plate 73. When it moves back and forth, it fits the upper surface of the horizontal filter plate 73 throughout the entire process. A flexible bonding strip can be added to the edge of the push plate 75 to improve the bonding and sealing performance and adapt to the bonding requirements after slight deformation of the filter plate; It thoroughly removes all solid contaminants from the surface of the horizontal filter plate 73, leaving no residue or accumulation, preventing clogging of the filter plate pores, and improving the thoroughness of automatic slag removal.

[0034] Preferably, the upper side of the reciprocating screw 74 is not within the feeding range of the conveyor belt 3, and the position of the reciprocating screw 74 protrudes from the conveyor belt 3, so that the material on the conveyor belt 3 does not fall onto the reciprocating screw 74.

[0035] In this implementation case, the reciprocating screw 74 is arranged outside the material conveying range of the conveyor belt 3, and the top of the reciprocating screw 74 is lower than the lower surface of the conveyor belt 3, so there is no path for material to fall and contact it. A protective cover can be added to further isolate the transmission structure, making it suitable for use in food processing scenarios with high dust levels; Completely prevent conveyed materials from falling and contaminating the transmission screw structure, prevent material jamming from causing equipment failure, and ensure long-term stable operation of the equipment.

[0036] The preferred drive pulley 84 and driven pulley 85 have various specifications and ratios.

[0037] In this implementation case, the driving pulley 84 and the driven pulley 85 are equipped with multiple sets of optional structures with different diameter specifications, and different specifications correspond to different transmission speed ratios. Different sizes of pulleys can be quickly replaced to adjust the speed without replacing the motor body, adapting to different power requirements for cleaning and drying; The pump and fan speeds can be flexibly adjusted to adapt to cleaning and drying needs under various working conditions, including light and heavy pollution, thus improving the equipment's adaptability to different working conditions.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
