Description

Technical Field

[0001] This invention relates to the field of freeze-drying technology, and more particularly to a conveying device based on a food production line. Background Technology

[0002] In the fruit freeze-drying, sorting, and washing processes of food production lines, conveying devices are core supporting equipment. They are mainly used to achieve continuous and automated conveying and transfer of fruit materials, and their operational stability and material protection effect directly determine the processing quality of the finished fruit. Currently, traditional fruit and food conveying devices on the market have relatively simple structures, mostly using fixed-angle conveyor belts with simple sidewall structures to complete material conveying, which has shortcomings in actual production applications.

[0003] Existing conveyor systems lack dedicated anti-compression structures for fruits. When the conveyor belt is inclined, the fruits, due to the component of gravity, tend to accumulate at the lower end of the conveyor surface, causing compression between fruits and between fruits and the side structures. This easily leads to problems such as damage to the fruit skin, deformation of the flesh, and bruising. Especially in freeze-drying fruit processing, damaged fruit skin and flesh result in deformities, uneven quality, and a lower yield of qualified products during freeze-drying, severely affecting product appearance and edibility, and increasing production losses.

[0004] In addition, the vibrations generated by the equipment during the conveying process will be directly transmitted to the fruit material, further aggravating the damage to the material and failing to meet the requirements of automated conveying production of high-quality fruit. Summary of the Invention

[0005] This invention proposes a conveying device based on a food production line to address the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a conveying device based on a food production line, including a support mechanism, and further including: a conveying mechanism connected to the support mechanism, wherein the conveying mechanism includes a conveyor belt, and a plurality of feeding plates are fixed on the outer surface of the conveyor belt; An angle adjustment mechanism, which is connected to a support mechanism and a conveying mechanism, includes two support rods. A bearing seat is fixed to the top of the support rods. A roller is installed inside the bearing seat. A support plate is provided on the top of the roller. A groove is opened at the bottom of the support plate. The roller is sleeved inside the groove. The fruit anti-pressure adjustment mechanism, which is connected to the conveying mechanism, includes an installation groove on the top of the feeding plate, a lifting plate is installed inside the installation groove, an L-shaped plate is fixed to one side of the lifting plate, an elastic sheet is provided between the two feeding plates, one side of the elastic sheet is fixedly connected to the L-shaped plate, and the other side is fixedly connected to the feeding plate, rollers are rotatably connected to both sides of the lifting plate, and hydraulic cylinders are fixed to both sides of the conveyor belt, with a C-shaped plate fixed to the extended end of the hydraulic cylinder.

[0007] Furthermore, the support mechanism includes a support frame, with rotating shafts rotatably connected to both sides of the support frame, and the rotating shafts being fixedly connected to the conveyor belt; an anti-slip pad is fixed to the bottom of the support frame.

[0008] Furthermore, the conveyor belt includes a metal mesh belt and multiple drive rollers, with the metal mesh belt sleeved over the multiple drive rollers.

[0009] Furthermore, the angle adjustment mechanism also includes two mounting slots 2 formed on the top of the support frame, the support rod is sleeved inside the mounting slot 2, a push rod motor is fixed to the inner wall of the mounting slot 2, and the output end of the push rod motor is fixedly connected to the bottom of the support rod; the support plate is fixedly connected to the conveyor belt.

[0010] Furthermore, the fruit anti-pressure adjustment mechanism also includes multiple springs fixed to the inner wall of the mounting groove. The top of the springs is fixedly connected to the lifting plate, and the roller is in contact with the edge of the side plate of the conveyor belt. Two partitions are fixed to the inner wall of the C-shaped plate to prevent the fruit from falling off the side after the elastic sheet tilts.

[0011] Furthermore, the fruit anti-pressure adjustment mechanism also includes a hinge component one fixed to the bottom of the support plate. The hinge component one is rotatably connected to a hydraulic cylinder two. The extended end of the hydraulic cylinder two is rotatably connected to the hinge component two. The hinge component two is fixedly connected to one side of the support rod.

[0012] Furthermore, both hydraulic cylinder one and hydraulic cylinder two include an outer cylinder and a piston rod. The piston rod is movably sleeved inside the outer cylinder. The outer cylinders of hydraulic cylinder one and hydraulic cylinder two are connected by an oil pipe. Both hydraulic cylinder one and hydraulic cylinder two are filled with hydraulic oil, which flows along the oil pipe.

[0013] Furthermore, the elastic sheet has multiple through holes.

[0014] Furthermore, the spring is in a contracted state.

[0015] Furthermore, a controller is fixed to one side of the support frame, and the controller is electrically connected to the push rod motor.

[0016] Compared with existing technologies, the beneficial effects of this invention are: 1. This invention uses a push rod motor to drive the support rod to rise and fall vertically. With the sliding cooperation between the top roller and the support plate groove, the entire conveyor belt can rotate flexibly around the shaft, achieving precise and stepless adjustment of the conveying angle. Compared with traditional fixed-angle conveying equipment, the conveying slope can be flexibly adjusted according to the specifications of the fruit materials, the processing steps of the production line, and the conveying efficiency requirements.

[0017] 2. This invention, by installing a fruit anti-pressure adjustment mechanism and relying on the connected hydraulic structure of hydraulic cylinder one and hydraulic cylinder two, can achieve linkage and adaptive adjustment of the conveyor belt inclination angle and the working state of the elastic plate. When the conveyor belt inclination angle changes, the hydraulic oil flows directionally in the connecting pipeline, driving the C-shaped plate to move precisely. With the linkage structure of rollers, lifting plates, and L-shaped plates, the inclined elastic plate can be automatically pulled flat during the material conveying process, and the fruit piled up at low points can be evenly spread out, eliminating the compressive stress caused by the accumulation of fruit, avoiding damage to the fruit skin and deformation and bruising of the fruit flesh, thereby improving the processing quality of freeze-dried fruit and other finished products from the source and reducing production material loss.

[0018] 3. The present invention utilizes the deformable structure design of the elastic sheet. When the elastic sheet is in a horizontal state, a gap is formed between its bottom and the surface of the conveyor belt. The buffer structure isolates the mechanical vibration generated by the operation of the equipment, preventing the vibration from being directly transmitted to the fruit material, and effectively reducing the secondary damage to the fruit caused by vibration during the conveying process.

[0019] 4. This invention achieves synchronous adaptation of tilt angle adjustment and material anti-compression leveling through the linkage of various structures and a single power linkage, without the need for separate manual control. It has a high degree of automation and effectively reduces the cost of manual operation and the difficulty of debugging. Attached Figure Description

[0030] Example: Refer to Figures 1-6 A conveying device based on a food production line includes a support mechanism and a conveying mechanism connected to the support mechanism. The conveying mechanism includes a conveyor belt 2, and multiple feeding plates 3 are fixed on the outer surface of the conveyor belt 2. An angle adjustment mechanism, which is connected to a support mechanism and a conveying mechanism, includes two support rods 12. A bearing seat 13 is fixed to the top of the support rod 12. A roller 14 is installed inside the bearing seat 13. A support plate 15 is provided on the top of the roller 14. A groove 16 is opened at the bottom of the support plate 15. The roller 14 is sleeved inside the groove. The fruit anti-pressure adjustment mechanism, which is connected to the conveying mechanism, includes an installation groove 1 opened on the top of the feeding plate 3, a lifting plate 5 is installed inside the installation groove 1, an L-shaped plate 6 is fixed on one side of the lifting plate 5, an elastic sheet 7 is provided between the two feeding plates 3, one side of the elastic sheet 7 is fixedly connected to the L-shaped plate 6, and the other side is fixedly connected to the feeding plate 3, rollers 8 are rotatably connected to both sides of the lifting plate 5, and hydraulic cylinders 9 are fixed to both sides of the conveyor belt 2, with a C-shaped plate 10 fixed to the extended end of the hydraulic cylinder 9.

[0031] The support mechanism includes a support frame 1, with rotating shafts 20 rotatably connected to both sides of the support frame 1, and the rotating shafts 20 are fixedly connected to the conveyor belt 2; an anti-slip pad is fixed to the bottom of the support frame.

[0032] With the support frame 1 as the load-bearing base, the rotating shafts 20 on both sides drive the transmission rollers of the conveyor belt 2 to rotate, causing the metal mesh belt to circulate. Multiple feeding plates 3 fixed to the outer surface of the conveyor belt 2 move synchronously with the belt body, forming lateral side barriers to limit the freeze-dried fruit entering the conveying surface, separating the fruit in the area between two adjacent feeding plates 3, and completing the upward conveying with the conveyor belt 2.

[0033] The conveyor belt 2 includes a metal mesh belt and multiple drive rollers, with the metal mesh belt sleeved over the multiple drive rollers.

[0034] The angle adjustment mechanism also includes two mounting slots 2 opened on the top of the support frame 1. The support rod 12 is sleeved inside the mounting slot 2. A push rod motor is fixed on the inner wall of the mounting slot 2. The output end of the push rod motor is fixedly connected to the bottom of the support rod 12. The support plate 15 is fixedly connected to the conveyor belt 2.

[0035] When the conveying angle of the conveyor belt 2 is adjusted by the angle adjustment mechanism, the controller drives the push rod motor installed in the mounting groove 2 of the support frame 1 to move, causing the support rod 12 to rise and fall vertically along the mounting groove 2. The roller 14 at the top of the support rod 12 rolls in the sliding groove 16 at the bottom of the support plate 15. Relying on the fixed connection between the support plate 15 and the conveyor belt 2, the entire conveyor belt 2 is driven to rotate around the lower rotating shaft 20, thereby achieving precise adjustment of the conveying angle.

[0036] The greater the inclination angle of the conveyor belt 2, the greater the contraction of the hydraulic cylinder 2 18, and the greater the displacement transmitted through the hydraulic oil, so that the C-shaped plate 10 moves further and the roller 8 is lifted to a higher height, thereby ensuring that the elastic sheet 7 is always in a horizontal state, accurately adapting to the degree of fruit accumulation at different inclination angles, and always maintaining the best anti-pressure and flattening effect.

[0037] The fruit anti-pressure adjustment mechanism also includes multiple springs 4 fixed to the inner wall of the mounting groove. The top of the springs 4 is fixedly connected to the lifting plate 5, and the rollers 8 are in contact with the edge of the side plate of the conveyor belt 2. Two partitions 11 are fixed to the inner wall of the C-shaped plate 10. The partitions 11 prevent the fruit from falling off the side after the elastic sheet tilts.

[0038] The fruit anti-pressure adjustment mechanism also includes a hinge 17 fixed to the bottom of the support plate 15. A hydraulic cylinder 18 is rotatably connected inside the hinge 17. A hinge 19 is rotatably connected to the extended end of the hydraulic cylinder 18. The hinge 19 is fixedly connected to one side of the support rod 12.

[0039] When the rollers 8 connected to both sides of the lifting plate 5 come into contact with the inlet ramp of the C-shaped plate 10, the rollers 8 are pushed upward by the ramp, causing the lifting plate 5 to overcome the contraction force of the spring 4 in the mounting groove and slide upward inside the mounting groove of the feeding plate 3.

[0040] As the lifting plate 5 moves upward, the L-shaped plate 6 fixed on its side pulls one edge of the elastic sheet 7 upward, gradually pulling the elastic sheet 7, which was originally tilted with the conveyor belt 2, to a horizontal state. This evenly spreads the fruit piled up at the low point in the area onto the surface of the elastic sheet 7, eliminating the compressive stress between the fruit. When the elastic sheet 7 is tilted, a gap is formed between it and the surface of the conveyor belt, and the bottom of the elastic sheet 7 is air, which can reduce the impact of vibration on the fruit during the conveying process.

[0041] By installing a fruit anti-pressure adjustment mechanism, relying on the interconnected hydraulic structure of hydraulic cylinder one and hydraulic cylinder two, the linkage and adaptive adjustment of the conveyor belt inclination angle and the working state of the elastic plate can be realized. When the conveyor belt inclination angle changes, the hydraulic oil flows directionally in the connecting pipeline, driving the C-shaped plate to move precisely. With the linkage structure of rollers, lifting plates, and L-shaped plates, the inclined elastic plate can be automatically pulled flat during the material conveying process, and the fruits piled up at low points can be evenly spread out, eliminating the compressive stress caused by the accumulation of fruits, avoiding damage to the fruit skin and deformation and bruising of the fruit flesh, thereby improving the processing quality of freeze-dried fruits and other finished products from the source and reducing production material loss.

[0042] The deformable structure design of the elastic sheet creates a gap between its bottom and the surface of the conveyor belt when the elastic sheet is in a horizontal state. This buffer structure isolates the mechanical vibration generated by the equipment operation, preventing the vibration from being directly transmitted to the fruit material and effectively reducing secondary damage to the fruit caused by vibration during the conveying process.

[0043] Both hydraulic cylinder 9 and hydraulic cylinder 18 include an outer cylinder and a piston rod. The piston rod is movably sleeved inside the outer cylinder. The outer cylinders of hydraulic cylinder 9 and hydraulic cylinder 18 are connected by an oil pipe. Both hydraulic cylinder 9 and hydraulic cylinder 18 are filled with hydraulic oil, which flows along the oil pipe.

[0044] Multiple through holes are provided on the elastic sheet 7.

[0045] Spring 4 is in the contracted state.

[0046] A controller is fixed on one side of the support frame 1, and the controller is electrically connected to the push rod motor.

[0047] Working principle: This device uses a support frame 1 as its load-bearing foundation. The rotating shafts 20 on both sides drive the transmission rollers of the conveyor belt 2 to rotate, which in turn drives the metal mesh belt to circulate. Multiple feeding plates 3 fixed to the outer surface of the conveyor belt 2 move synchronously with the belt body, forming lateral guards to limit the freeze-dried fruit entering the conveyor surface, separating the fruit in the area between two adjacent feeding plates 3, and allowing it to be conveyed upward with the conveyor belt 2.

[0048] When the conveyor belt 2 is in an inclined conveying state, under the influence of gravity, the fruit between adjacent feeding plates 3 will slide and gather towards the lower feeding plate 3, forming a local accumulation. The accumulated fruit is squeezed against each other and against the side wall of the feeding plate 3, which can easily cause skin damage and flesh deformation, thus affecting the quality of the freeze-dried product.

[0049] When adjusting the conveyor belt 2's tilt angle, the controller drives the push rod motor installed in the mounting slot 2 of the support frame 1, causing the support rod 12 to rise and fall vertically along the mounting slot 2. The roller 14 at the top of the support rod 12 rolls in the sliding groove 16 at the bottom of the support plate 15. Relying on the fixed connection between the support plate 15 and the conveyor belt 2, the entire conveyor belt 2 rotates around the lower rotating shaft 20, achieving precise adjustment of the conveyor tilt angle. The larger the tilt angle of the conveyor belt 2, the greater the contraction of the hydraulic cylinder 18, and the greater the displacement transmitted through the hydraulic oil. This allows the C-shaped plate 10 to move further, and the roller 8 to be lifted higher, thus ensuring that the elastic sheet 7 remains horizontal, precisely adapting to the degree of fruit accumulation at different tilt angles, and always maintaining the best anti-pressure and flattening effect.

[0050] During this process, the second hydraulic cylinder 18, which is hinged between the support plate 15 and the support rod 12, is passively extended as the tilt angle changes. The hydraulic oil inside it flows directionally between the second hydraulic cylinder 18 and the first hydraulic cylinder 9 through the connecting oil pipe, thereby driving the piston rod of the first hydraulic cylinder 9 to move the C-shaped plate 10 along the width direction of the conveyor belt 2 to the preset position and maintain that state.

[0051] After the C-shaped plate 10 is positioned, each feeding plate 3, which moves cyclically with the conveyor belt 2, passes through the area of ​​the C-shaped plate 10 in sequence.

[0052] When the rollers 8 connected to both sides of the lifting plate 5 come into contact with the inlet ramp of the C-shaped plate 10, the rollers 8 are pushed upward by the ramp, causing the lifting plate 5 to overcome the contraction force of the spring 4 in the mounting groove and slide upward inside the mounting groove of the feeding plate 3.

[0053] As the lifting plate 5 moves upward, the L-shaped plate 6 fixed on its side pulls one edge of the elastic sheet 7 upward, gradually pulling the elastic sheet 7, which was originally tilted with the conveyor belt 2, to a horizontal state. This evenly spreads the fruit piled up at the low point in the area onto the surface of the elastic sheet 7, eliminating the compressive stress between the fruit. When the elastic sheet 7 is tilted, a gap is formed between it and the surface of the conveyor belt, and the bottom of the elastic sheet 7 is air, which can reduce the impact of vibration on the fruit during the conveying process.

[0054] When the roller 8 moves smoothly along the top surface of the C-shaped plate 10 to the exit ramp, the contraction force of the spring 4 begins to be released, causing the lifting plate 5 and the roller 8 to return to their original positions synchronously. Under the action of its own elastic restoring force, the elastic plate 7 gradually returns to an inclined state parallel to the conveyor belt 2. At this time, the fruit has been transported to the end, and the transportation is completed.
