Description

Technical Field

[0001] The utility model belongs to the technical field of feeding and discharging materials, and in particular relates to a power-assisted feeding and discharging system of a vacuum cooling machine. Background Art

[0002] Silkworms, commonly known as silkworms or domesticated silkworms, are economic insects that feed on mulberry leaves and spin silk cocoons. They belong to the order Lepidoptera, family Bombycidae. Silkworms originated in China. Their development temperature ranges from 7-40°C, and their optimal rearing temperature is 20-30°C. They are primarily found in temperate, subtropical, and tropical regions. Traditionally, silkworms have been reared in small, family-run workshops, a completely manual process. From egg-to-mature stage to cocoon harvesting, all operations are manual, time-consuming and labor-intensive, resulting in very low production efficiency. Furthermore, due to seasonal constraints, silkworms can only be reared at specific times, resulting in extremely low annual cocoon production, which is unable to meet the needs of today's society and has been gradually phased out.

[0003] To address the shortcomings of traditional workshop-style silkworm farming, large-scale, factory-based silkworm farming techniques were developed. However, using mulberry leaves as feed in these large-scale farming techniques would be completely inadequate to meet the requirements of factory-based silkworm farming. Therefore, artificial feed plays a crucial role in factory-based, large-scale silkworm farming.

[0004] In the processing of artificial feed, a vacuum cooler is used to cool the feed. A vacuum cooler, also known as a vacuum pre-cooler, vacuum quick cooler, vacuum easy cooler, vacuum fast cooler, etc., is a device that quickly cools, pre-cools, and preserves moisture-rich substances (such as high-temperature cooked food, soups, fresh fruits and vegetables, and other foods) under a vacuum state. In the prior art, the materials of the vacuum cooler are placed on trays or special containers, and then fed into or out of the vacuum cooler as a whole to achieve batch feeding or discharging of the vacuum cooler. However, this feeding or discharging requires more time and manpower to complete the loading or unloading process, resulting in relatively low loading and unloading efficiency.

[0005] Patent Document 1 (publication number CN213335084U) discloses a "vacuum cooling machine" that describes how an operator places food on a tray and then pushes the tray into a box to achieve the desired placement. This clearly demonstrates the use of the tray as a container for the material. Once the material is placed on the tray, it is fed into the vacuum cooling machine as a whole. To remove the material, the tray is removed from the box. This requires considerable time and manpower to complete, impacting efficiency.

[0006] Existing patent document 2 (publication number CN213127894U) discloses "a vacuum cooling machine", which records that the inner cavity of the box is fixedly provided with a shelf, and the lower side wall of the shelf is fixedly provided with a pulley. The shelf can be pulled out by the pulley to place food, making it convenient to place and take out. The shelf serves as a container for placing materials. After the materials are placed on the shelf, they are pushed into the box. When taking out, the shelf is pulled out as a whole to achieve the removal of the materials. The loading and unloading of materials also requires more manpower and time to complete, resulting in relatively low loading and unloading efficiency. Summary of the Invention

[0007] The purpose of the utility model is to provide a technical solution for the vacuum cooling machine auxiliary feeding and discharging system to address the deficiencies in the existing technology. The utility model has an ingenious design and is easy to use. The feeding and discharging system can assist the material box in being fed into and out of the vacuum cooling machine, thereby effectively improving the loading and unloading efficiency and ensuring the accuracy of loading and unloading. The entire system is simple to operate. It only requires placing the material box on the conveying track, and the system then drives the pushing device to move through the conveying chain device to realize automatic pushing and conveying process. The degree of automation is high, which effectively reduces labor costs and improves production efficiency.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] The vacuum cooler's assisted feeding and discharging system includes a frame, a conveying track, a pushing device, a conveying chain device and a lap joint device. The conveying track is arranged in the frame, the pushing device is arranged at one end of the frame, the pushing device is slidably arranged on the frame, the conveying chain device is arranged on the frame, the conveying chain device is connected to the pushing device, the conveying chain device drives the pushing device to move along the frame, and the pushing device pushes the material box to move along the conveying track during movement. The lap joint device is arranged at the other end of the frame, and the conveying track and the track inside the vacuum cooler are overlapped by the lap joint device, so that the material box is transferred from the conveying track to the track inside the vacuum cooler.

[0010] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0011] The utility model discloses a conveyor track that defines the moving path of the material box, improves the transmission accuracy of the material box, and then drives the pushing device to move through the conveyor chain device, so as to achieve smooth and rapid movement of the material box, thereby effectively improving production efficiency. The entire system is simple to operate. Only by placing the material box on the conveyor track, the system can automatically complete the pushing and conveying process. A lap joint device is provided between the conveyor track and the vacuum cooler, and the lap joint device is used to achieve a lap connection between the conveyor track and the track inside the vacuum cooler, ensuring that the material can be smoothly and seamlessly transferred from the conveyor track to the inside of the vacuum cooler, avoiding the risk of the material box tilting or tipping during the transfer process, thereby improving the stability and safety of the entire system operation. When the vacuum cooler is saturated with material, the pushing device continues to push the material box into the vacuum cooler. When a group of material boxes are pushed into the vacuum cooler, a group of material boxes in the vacuum cooler will also be pushed out from the exit end of the track inside the vacuum cooler at the same time. The pushed material boxes are guided out by the guide slope at the exit end, thereby realizing an automated loading and unloading process, effectively improving loading and unloading efficiency.

DETAILED DESCRIPTION

[0020] like Figures 1 to 6 As shown, the utility model is a power-assisted feeding and discharging system of a vacuum cooling machine, comprising a frame 1, a conveying track 2, a pushing device 3, a conveying chain device 4 and a lap joint device 5. The conveying track 2 is arranged in the frame 1, the pushing device 3 is arranged at one end of the frame 1, the pushing device 3 is slidably arranged on the frame 1, the conveying chain device 4 is arranged on the frame 1, the conveying chain device 4 is connected to the pushing device 3, the conveying chain device 4 drives the pushing device 3 to move along the frame 1, and the pushing device 3 pushes the material box 9 to move along the conveying track 2 during the movement. The lap joint device 5 is arranged at the other end of the frame 1, and the conveying track 2 and the inner track 40 of the vacuum cooling machine are overlapped and connected through the lap joint device 5, so that the material box 9 is transferred from the conveying track 2 to the inner track 40 of the vacuum cooling machine. The frame 1 includes two symmetrically arranged side support rods 37, and support columns 38 are evenly arranged on the side support rods 37. The drive motor 22 is arranged on the side support rod 37 on one side, and the drive main shaft 24 is rotatably arranged between the two side support rods 37. The two conveyor chain assemblies are respectively located on the two side support rods 37. The conveyor track 2 is arranged between the two side support rods 37, and the layout direction of the conveyor track 2 is parallel to the length direction of the side support rods 37. The pushing device 3 is horizontally erected between the two side support rods 37. The evenly distributed support columns 38 can ensure the structural stability and balance of the entire frame 1, and improve the overall bearing capacity of the frame 1.

[0021] The conveying track 2 limits the moving path of the material box 9, improves the transmission accuracy of the material box 9, and then drives the pushing device 3 to move through the conveying chain device 4, so as to realize the smooth and rapid movement of the material box 9, thereby effectively improving the production efficiency. The whole system is simple to operate. It only needs to place the material box 9 on the conveying track 2, and the system can automatically complete the pushing and conveying process. A lap joint device 5 is set between the conveying track 2 and the vacuum cooler 39. The lap joint device 5 realizes the lap connection between the conveying track 2 and the track 40 inside the vacuum cooler, ensuring that the material can be smoothly and seamlessly transitioned from the conveying track 2 to the inside of the vacuum cooler 39, avoiding the risks of tilting, overturning, etc. of the material box 9 during the transfer process, and improving the stability and safety of the entire system operation. When the vacuum cooler 39 is saturated with material, the pushing device 3 continues to push the material box 9 into the vacuum cooler 39. When a group of material boxes 9 are pushed into the vacuum cooler 39, a group of material boxes 9 in the vacuum cooler 39 will be simultaneously pushed out from the exit end of the track 40 in the vacuum cooler. The pushed out material boxes 9 are guided out through the guide slope 41 at the exit end, thereby realizing the automated loading and unloading process and effectively improving the loading and unloading efficiency.

[0022] There are at least two groups of conveyor rails 2, and several conveyor rails 2 are evenly distributed in the frame 1. The structural design is ingenious and reasonable. The evenly distributed design can ensure the stability and balance of the overall structure, which is more conducive to the smooth transmission of the material box 9. The design of multiple groups of conveyor rails 2 makes it possible to transport multiple material boxes 9 at the same time, thereby effectively improving the transmission efficiency. When one group of conveyor rails 2 fails or needs maintenance, the other conveyor rails 2 can continue to work to ensure production continuity. The conveyor rails 2 include track line 1 6 and track line 2 7. Track line 1 6 and track line 2 7 are both provided with track grooves 8. A movable pulley 10 is provided at the bottom of the material box 9. The material box 9 is provided between track line 1 6 and track line 2 7. The movable pulley 10 is limited and slides in the track groove 8. The design of the movable pulley 10 can be more conducive to the smooth transmission of the material box 9 along the conveyor rail 2, and cooperates with the design of the track groove 8 on the track line so that the movable pulley 10 is limited, effectively enhancing the stability of the material box 9 during transmission and reducing the shaking and tilting of the material box 9 during transmission.

[0023] Track line 1 6 and track line 2 7 both include an integrally formed feed section 11, an oblique section 12 and a translation section 13. The oblique section 12 is obliquely connected between the feed section 11 and the translation section 13. The feed section 11 is supported on a placement surface, and the translation section 13 is supported on a support frame 14. A guide flare 15 is provided at the port of the feed section 11. The feed section 11, the oblique section 12 and the translation section 13 are integrally formed to ensure the continuity and stability of the track line and improve the structural stability of the track line. The feed section 11 is the initial section of the conveyor track 2. Generally, It is placed directly flat on the placement surface, which makes it convenient to push the material box 9 from the outside to the conveying track 2, and the design of the guide expansion 15 at the port of the feed section 11 is more conducive to the material box 9 sliding smoothly into the conveying track 2, avoiding the material box 9 from getting stuck at the entrance. The oblique section 12 plays a guiding role, so that the pushing device 3 can gradually push the material box 9 to the translation section 13. The support frame 14 is supported and arranged under the conveying track 2 to ensure the stability and firmness of the track. There are multiple support frames 14, which are adaptively adjusted according to the length of the translation section 13.

[0024] The lap joint device 5 corresponds to the conveying track 2 one by one. The lap joint device 5 includes a mounting seat 16, a lap rail 17 and a lap cylinder 18. The mounting seat 16 is supported at the end of the conveying track 2. The mounting seat 16 ensures the overall structural stability and reliability of the lap joint device 5. The mounting seat 16 is also supported at the end of the corresponding conveying track 2 to provide auxiliary support for the conveying track 2, making the conveying track 2 structure more stable and reliable. The lap rail 17 is rotatably hinged with the mounting seat 16, and the lap cylinder 18 is rotated. The hinged connection is mounted on mounting base 16. The piston rod end of lap cylinder 18 is movably hinged to lap track 17. Lap track 17 comprises lap track 1 20 and lap track 2 21, which are fixedly connected via connecting rod 19. The piston rod of lap cylinder 18 retracts and retracts to rotate lap track 17. When lap track 17 is fully rotated, lap track 1 20 overlaps track line 1 6, and lap track 2 21 overlaps track line 2 7. The lap track 17 aligns conveyor track 2 with the internal track 40 of the vacuum cooler, ensuring continuity and stability during the transfer of material bin 9 and improving the efficiency and reliability of material transfer. The overlapping track 17 realizes automatic angle adjustment through the overlapping cylinder 18, which is easy to use and operate. Preferably, when the overlapping track 17 is rotated to a horizontal position, the overlapping track 17 is aligned and connected with the conveying track 2 and the vacuum cooler inner track 40. However, if there is a height difference between the conveying track 2 and the vacuum cooler inner track 40, the angle of the overlapping track 17 can be adjusted by the overlapping cylinder 18 to meet the overlapping connection between the conveying track 2 and the vacuum cooler inner track 40 with different height differences, thereby increasing the flexibility and reliability of the system.

[0025] The conveyor chain device 4 includes a drive motor 22, a drive sprocket 23, a drive spindle 24 and a conveyor chain assembly. The motor shaft of the drive motor 22 is connected to the drive sprocket 23. The drive spindle 24 is provided with a transmission sprocket 25. A transmission chain (not shown in the figure) is connected between the transmission sprocket 25 and the drive sprocket 23. Conveyor chain assemblies are provided on both sides of the pushing device 3. The conveyor chain assembly includes a driving sprocket 26 and a passive sprocket 27. A conveyor chain (not shown in the figure) is connected between the driving sprocket 26 and the passive sprocket 27. The conveyor chain is connected to the pushing device 3. The driving sprockets 26 on the two conveyor chain assemblies are both fixedly connected to the drive spindle 24. The driving motor 22 drives the driving sprocket 23 to rotate, and the driving sprocket 23 drives the driving sprocket 25 to rotate through the transmission chain. The transmission sprocket 25 is fixed to the driving main shaft 24, thereby realizing the synchronous linkage of the driving main shaft 24. The two ends of the driving main shaft 24 are respectively connected to the active sprockets 26 on the two conveyor chain assemblies, thereby driving the synchronous operation of the two conveyor chain assemblies, ensuring the smooth and reliable operation of the entire conveyor chain device 4, and driving the conveyor chain to rotate through the active sprocket 26. The two conveyor chains are connected to the pushing device 3, so that the pushing device 3 is driven by the conveyor chain to move smoothly along the conveying track 2, and then the material box 9 is smoothly transported and moved into the vacuum cooler 39 through the pushing device 3, so that the material transportation is smooth and reliable, and the operation safety is improved.

[0026] The pushing device 3 includes a pushing frame 28, a pushing roller 29, a connecting rod 30 and an adjusting cylinder 31. The pushing frame 28 is horizontally mounted on the frame 1. A sliding block 32 is provided at the bottom end of the pushing frame 28. The sliding block 32 is slidably connected to the frame 1. The adjusting cylinder 31 and the connecting rod 30 are hingedly set on the pushing frame 28. Connecting rods 30 and adjusting cylinders 31 are provided on both sides of the pushing frame 28. The piston rod end of the adjusting cylinder 31 on the corresponding side is hinged to the connecting rod 30. The pushing roller 29 is connected between the two connecting rods 30. A connecting screw 33 is provided on the pushing frame 28. The connecting screw 33 is fixedly mounted on the sliding block 32. The connection and fixation between the pushing frame 28 and the conveying chain are achieved through the connecting screw 33. The pusher 28 is slidably connected to the frame 1 through the sliding block 32, so that the pusher 28 slides on the frame 1 along a specific direction. At the same time, a guide pulley is connected to the sliding block 32, and the guide pulley is in rolling contact with the side of the frame 1. The design of the guide pulley can reduce the friction resistance of the pusher 28 during the sliding process, making the sliding smoother. At the same time, the guide pulley can also ensure the stability of the pusher 28 during the sliding process, avoiding deviation or shaking. When the pusher 28 moves, the push roller 29 will contact the side of the material box 9, pushing the material box 9 to move synchronously along the conveyor track 2. The connecting screw 33 can facilitate the connection and fixation between the conveyor chain and the pusher 28, so that when the conveyor chain moves, The pushing rack 28 will also move accordingly to ensure the synchronization between the pushing device 3 and the conveyor chain device 4, thereby ensuring that the material can be pushed into place accurately and timely, and by adjusting the cylinder 31, the angle of the connecting rod 30 can be driven to change, and then the connecting rod 30 drives the adjustment of the angle of the pushing roller 29, so that the conveyor chain device 4 drives the pushing device 3 to move during the reset process. By adjusting the angle of the pushing roller 29, the pushing roller 29 will not interfere with the unloaded material box 9 on the conveyor track 2 during the reset process. When the pushing device 3 is reset, the adjusting cylinder 31 will adjust the angle of the pushing roller 29 again, so that the pushing roller 29 rotates down into place, which is convenient for the subsequent pushing device 3 to push and convey the material box 9.

[0027] The frame 1 is provided with a chain support 34, which supports the conveyor chain. The chain support 34 is arranged along the length direction of the frame 1 to stably support and guide the conveyor chain so that the conveyor chain can move according to the predetermined path, prevent the conveyor chain from deviating or falling off, help improve the conveying efficiency, and ensure the continuous operation of the system. During actual installation, the chain support 34 can be installed at one of the conveyor chains, or at both conveyor chains. A limit rod 35 is provided below the connecting rod 30, and a limit support surface 36 is provided at the end of the limit rod 35. The limit rod 35 is fixedly connected to the pusher frame 28. The limit rod 35 provides stable support for the connecting rod 30 after it is rotated into place, preventing the push roller 29 from deviating or shaking during the pushing process, making the push roller 29 more stable and accurate during the pushing process, thereby improving the stability and reliability of the operation of the pusher device 3.

[0028] The present invention is ingeniously designed and easy to use. The feeding and unloading system can assist the material box 9 in being fed into and out of the vacuum cooler 39, thereby effectively improving the efficiency of loading and unloading and ensuring the accuracy of loading and unloading. The entire system is simple to operate. The material box 9 only needs to be placed on the conveyor track 2. The system then drives the pusher device 3 to move through the conveyor chain device 4 to achieve automatic pushing and conveying. The degree of automation is high, which effectively reduces labor costs and improves production efficiency. The conveyor track 2 defines the movement path of the material box 9, improving the transmission accuracy of the material box 9. The conveyor chain device 4 then drives the pusher device 3 to move, achieving smooth and rapid movement of the material box 9, thereby effectively improving production efficiency. A lap joint device 5 is provided between the conveyor track 2 and the vacuum cooler 39. The lap joint device 5 realizes the lap connection between the conveyor track 2 and the inner track 40 of the vacuum cooler, ensuring that the material can be smoothly and seamlessly transferred from the conveyor track 2 to the interior of the vacuum cooler 39, avoiding the risk of the material box 9 tilting or tipping during the transfer process, and improving the stability and safety of the entire system operation. When the vacuum cooler 39 is saturated with material, the pushing device 3 continues to push the material box 9 into the vacuum cooler 39. When a group of material boxes 9 are pushed into the vacuum cooler 39, a group of material boxes 9 in the vacuum cooler 39 will be simultaneously pushed out from the exit end of the track 40 in the vacuum cooler. The pushed out material boxes 9 are guided out through the guide slope 41 at the exit end, thereby realizing the automated loading and unloading process and effectively improving the loading and unloading efficiency.

[0029] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications based on the present invention to achieve substantially the same technical effects are included within the scope of protection of the present invention.
