Description

Technical Field

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

[0002] A vacuum chiller, also known as a vacuum pre-cooler, vacuum rapid chiller, vacuum quick chiller, or vacuum fast chiller, is a device that rapidly cools, pre-cools, and preserves moisture-rich materials (such as hot cooked foods, soups, and fresh fruits and vegetables) under vacuum. The vacuum chiller operates by reducing the surface pressure of water, which dramatically lowers its boiling point, by exploiting the fact that a higher vacuum reduces the boiling point. In a vacuum environment, water molecules vaporize, removing a significant amount of heat and rapidly cooling the material being cooled.

[0003] In existing vacuum chillers, materials are placed on trays or specialized containers and then fed into or out of the chiller en masse, enabling batch feeding or discharging. Persons skilled in the art utilize feeding and discharging systems to assist with batch material transport, typically using a pusher device for pushing and conveying. However, existing pushers suffer from limited stability and pose significant safety risks. Summary of the Invention

[0008] Furthermore, the pusher rack includes side brackets and a cross bar. The cross bar is fixedly connected between the two side brackets. The pusher roller is arranged between the two side brackets. Connecting rods are provided at both ends of the pusher roller. The connecting rods on the corresponding sides are rotatably hinged to the side brackets. Two L-shaped side brackets and a cross bar constitute the basic frame of the pusher rack to ensure the firmness and balance of the overall structure. The cross bar and the side brackets are preferably fixed by welding to ensure the strength and stability of the structural connection.

At the same time, adjusting cylinders are provided on both sides to ensure the balance and stability of the overall structure.

[0010] Furthermore, two sliding blocks are provided on the bottom surface of the two side brackets, and the two sliding blocks are symmetrically distributed at both ends of the bottom surface of the side brackets.

DETAILED DESCRIPTION

[0028] like Figures 1 to 9 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.

[0029] 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.

[0030] 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.

[0031] 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 feed end port 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 conveying track 2.

[0032] 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.

[0033] 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.

[0034] The pushing device 3 includes a pushing frame 28, a pushing roller 29 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. A sliding groove 42 is provided on the sliding block 32.

The adjusting cylinder 31 is set on the pushing frame 28, and the angle of the pushing roller 29 is adjusted by the extension and retraction of the piston rod of the adjusting cylinder 31. The overall structure of the pusher device 3 is stable and reliable. The design of the bottom sliding block 32 cooperates with the frame 1 to guide and limit the movement of the pusher device 3, making the movement of the pusher device 3 more stable and reliable, improving operational safety, and the overall operation is convenient and simple. The conveyor chain device 4 drives the pusher device 3 to move along the frame 1. During the movement, the pusher device 3 can push the material along the specific conveyor track 2 to achieve efficient and stable pushing of the material. At the same time, the adjustment cylinder 31 can adjust the angle of the pusher roller 29, thereby adjusting it according to the usage status, making it easier for the pusher device 3 to cooperate with the entire feeding and discharging system.

[0035] The pusher rack 28 includes a side bracket 43 and a cross bar 41. The cross bar 41 is fixedly connected between the two side brackets 43. The pusher roller 29 is arranged between the two side brackets 43. Connecting rods 30 are provided at both ends of the pusher roller 29. The connecting rods 30 on the corresponding sides are rotatably hinged with the side brackets 43. Two L-shaped side brackets 43 and a cross bar 41 constitute the basic frame of the pusher rack 28 to ensure the firmness and balance of the overall structure. The cross bar 41 and the side brackets 43 are preferably fixed by welding to ensure the strength and stability of the structural connection. The pusher roller 29 is just arranged between the two side brackets 43. The rotational hinge between the pusher roller 29 and the side brackets 43 is realized through the connecting rods 30 at both ends of the pusher roller 29. The overall structural design is reasonable and easy to install, which meets the requirements of the pusher device 3 for efficient and stable pushing of materials. The hinged connection between the connecting rod 30 and the side brackets 43 also facilitates the subsequent adjustment of the rotation angle of the pusher roller 29 by the cylinder. A reinforcing diagonal rod 46 is provided on the side bracket 43. The reinforcing diagonal rod 46 is obliquely arranged between the horizontal section of the side bracket 43 and the vertical section of the side bracket 43. The design of the reinforcing diagonal rod 46 can enhance the structural stability and bearing capacity of the side bracket 43, reduce deformation, and extend its service life.

[0036] An adjusting cylinder 31 is provided on each of the two side brackets 43, and the adjusting cylinder 31 is hinged to the side bracket 43. A connecting block 45 is provided on each of the two connecting rods 30. The piston rod end of the adjusting cylinder 31 on the corresponding side is hinged to the connecting block 45. The structural design is reasonable. The connecting block 45 realizes the movable connection between the adjusting cylinder 31 and the connecting rod 30, and the angle of the pushing roller 29 can be accurately adjusted through the adjusting cylinders 31 on both sides, so that the angle of the pushing roller 29 can be adaptively adjusted according to the use status of the pushing device. At the same time, the adjusting cylinders 31 on both sides can also ensure the balance and stability of the overall structure. Two sliding blocks 32 are provided on the bottom surface of the two side brackets 43. The two sliding blocks 32 are symmetrically distributed at both ends of the bottom surface of the side bracket 43. Two sliding blocks 32 are symmetrically provided on the bottom of each side bracket 43 to ensure the overall structural balance and stability of the pusher rack 28. At the same time, the sliding blocks 32 are convenient for the installation and fixation of the connecting screw 33 on the pusher rack 28. The sliding blocks 32 are slidably installed with the frame 1 to improve the movement stability and flexibility of the pusher rack 28 on the frame 1.

[0037] The pusher rack 28 is provided with a connecting screw 33 , which is preferably fixedly mounted on the sliding block 32 . The connection and fixation between the pusher rack 28 and the conveying chain are achieved through the connecting screw 33 , and a connecting hole is provided on the connecting screw 33 . The pusher rack 28 is slidably connected to the frame 1 through the sliding block 32, so that the pusher rack 28 slides on the frame 1 along a specific direction. At the same time, a guide pulley 48 is installed on the sliding block 32, and the guide pulley 48 is in rolling contact with the side of the frame 1. The design of the guide pulley 48 can reduce the friction resistance of the pusher rack 28 during the sliding process, making the sliding smoother. At the same time, the guide pulley 48 can also ensure the stability of the pusher rack 28 during the sliding process, avoiding deviation or shaking. When the pusher rack 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 conveying track 2. The connecting screw 33 can facilitate the connection and fixation between the conveying chain and the pusher rack 28. The design of the connecting hole facilitates the connection and installation between the conveying chain and the connecting screw 33, which is convenient for actual assembly. , so that when the conveyor chain moves, the pushing rack 28 will also move accordingly, ensuring 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 the connecting rod 30 can be driven to change its angle by adjusting the cylinder 31, 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 contact the unloaded material box 9 on the conveyor track 2 during the reset process, and 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 is rotated down to its position, that is, when the connecting rod 30 contacts the support on the limit rod 35, it is convenient for the subsequent pushing device 3 to push and convey the material box 9.

[0038] A chain support 34 is provided on the frame 1 to support 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 along a predetermined path, preventing the conveyor chain from deviating or falling off, thereby helping to improve the conveying efficiency and ensure the continuous operation of the system.

[0039] The limit rods 35 are provided on the two side brackets 43, and the limit rods 35 on the corresponding sides are located below the connecting rod 30. The end of the limit rod 35 is provided with a limit support surface 36, which plays a limiting role. The limit support surface 36 can ensure the contact area between the limit rod 35 and the connecting rod 30, and the rotation range of the push roller 29 is limited by the limit rod 35, which is more conducive to the precise adjustment and limit of the angle of the push roller 29, and prevents the push roller 29 from excessive rotation or misalignment causing malfunction, and provides stable support for the connecting rod 30 after it is rotated into place through the limit rod 35, preventing the push roller 29 from deflecting or shaking during the pushing process, so that the limit rod 35 can withstand part of the thrust and gravity during the pushing process of the push roller 29, so that the push roller 29 is more stable and accurate during the pushing process, thereby improving the stability and reliability of the operation of the push device 3 and extending the service life of the push device 3. One end of the connecting rod 30 is hinged to the side bracket 43, and the other end of the connecting rod 30 is connected to the push roller 29, and a limit block 47 is provided below the end of the connecting rod 30 connected to the push roller 29. The structural design is ingenious and reasonable. The connecting rod 30 ensures that the push roller 29 is stably installed between the side brackets 43 without affecting the adjustment of the angle of the push roller 29. When the connecting rod 30 is limited to support the limit rod 35, the limit block 47 is also limited at the corresponding end of the limit rod 35, ensuring that the angle of the push roller 29 is adjusted to a specific position. The limit block 47 and the limit rod 35 are limited together, which can effectively prevent the connecting rod 30 from excessive rotation.

[0040] 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.

[0041] 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.
