Description

Technical Field

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

[0002] Silkworms, commonly known as silkworm babies, are one of the economic insects that feed on mulberry leaves and spin silk cocoons. They belong to the order Lepidoptera, family Bombyx mori. Silkworms originated in China. Their development temperature is 7-40℃, and the optimum temperature for breeding is 20-30℃. They are mainly distributed in temperate, subtropical and tropical regions. The traditional breeding method is a family-style small workshop breeding method, which is a fully artificial breeding method. From silkworm eggs to adults to cocoons, it is all achieved through manual operation. It is time-consuming and labor-intensive, and the breeding efficiency is very low. In addition, due to seasonal conditions, silkworms can only be raised at specific times. The annual output of silkworm cocoons is extremely low, which cannot meet the needs of today's society at all, and has been gradually eliminated by society.

[0003] In order to make up for the shortcomings of traditional workshop-style silkworm farming, large-scale and factory-based silkworm farming technology was developed. In large-scale breeding technology, if mulberry leaves are used as feed, it is completely unable to meet the requirements of factory-based silkworm farming. Therefore, artificial feed plays an important role in factory-based and large-scale silkworm farming technology.

[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 a tray or a special container, and then sent 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] Existing patent document 1 (publication number CN213335084U) discloses "a vacuum cooling machine", which records that the operator places food on a pallet, and then pushes the pallet into the box to achieve the placement of food inside the box. Obviously, the pallet is used as a container for placing materials. After the materials are placed on the pallet, they are sent into the vacuum cooling machine as a whole. When taking out, the pallet is taken out from the box to achieve the removal of the materials. Both the feeding and taking out of materials require a lot of time and manpower to complete, which affects the actual efficiency.

[0006] Existing patent document 2 (publication number CN213127894U) discloses "a vacuum cooling machine", which records that a shelf is fixedly provided in the inner cavity of the box, and a pulley is fixedly provided on the lower side wall of the shelf. The shelf can be pulled out through the pulley to place food, which is convenient for placing and taking out. The shelf is used 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 realize the taking out 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 present invention is to provide a technical solution for a vacuum cooler auxiliary feeding and discharging system to address the deficiencies in the prior art. The system has a clever design and is easy to use. The feeding and discharging system can assist in feeding the material box into and out of the vacuum cooler, thereby effectively improving the efficiency of loading and unloading and ensuring the accuracy of loading and unloading. The entire system is easy 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 processes. The system has a high degree of automation, 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 power-assisted feeding and discharging system of the vacuum cooler 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 and connected through the lap joint device, so that the material box is transferred from the conveying track to the track inside the vacuum cooler.

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

[0011] The conveying track in the present invention limits 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 conveying chain device, so as to realize the smooth and rapid movement of the material box, thereby effectively improving the production efficiency. The whole system is simple to operate. It only needs to place the material box on the conveying track, and the system can automatically complete the pushing and conveying process. A lap joint device is set between the conveying track and the vacuum cooler, and the lap joint device is used to realize the lap connection between the conveying track and the track inside the vacuum cooler, so as to ensure that the material can smoothly and seamlessly transition from the conveying track to the inside of the vacuum cooler, avoid the risk of tilting, tipping over, etc. of the material box during the transfer process, and improve the stability and safety of the operation of the whole system. 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 outlet 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 outlet end, thereby realizing the automatic loading and unloading process, and effectively improving the loading and unloading efficiency.

DETAILED DESCRIPTION

[0020] like Figures 1 to 6 As shown, the vacuum cooler power feeding and discharging system of the present invention includes 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 is overlapped with the inner track 40 of the vacuum cooler 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 cooler. 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 driving motor 22 is arranged on the side support rod 37 on one side, and the driving main shaft 24 is rotatably arranged between the two side support rods 37. The two conveying chain assemblies are respectively located on the two side support rods 37. The conveying track 2 is arranged between the two side support rods 37, and the layout direction of the conveying 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. Only by placing the material box 9 on the conveying track 2, the system can automatically complete the pushing and conveying process, and a lap joint device 5 is provided between the conveying track 2 and the vacuum cooler 39. The lap joint device 5 is used to realize the lap connection between the conveying track 2 and the track 40 inside the vacuum cooler, so as to ensure that the material can smoothly and seamlessly transition from the conveying track 2 to the inside of the vacuum cooler 39, thereby avoiding the risks of tilting, tipping over, etc. of the material box 9 during the transfer process, and improving the stability and safety of the operation of the whole system. 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 also be pushed out from the exit end of the track 40 in the vacuum cooler at the same time. The pushed out material boxes 9 are guided and slide 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 tracks 2, and several conveyor tracks 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 tracks 2 allows multiple material boxes 9 to be transported at the same time, thereby effectively improving the transportation efficiency. When one group of conveyor tracks 2 fails or needs maintenance, other conveyor tracks 2 can continue to work to ensure production continuity. The conveyor track 2 includes a track line 1 6 and a track line 2 7. Track lines 1 6 and 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 the track line 1 6 and the track line 2 7. The movable pulley 10 is limited to slide 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 track 2, and the design of the track groove 8 on the track line is matched, so that the movable pulley 10 is limited, which effectively enhances the stability of the material box 9 during the transmission process and reduces the shaking and tilting of the material box 9 during the transmission process.

[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, the translation section 13 is supported and arranged on a support frame 14, and a guide flare 15 is arranged 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 conveying track 2, generally It is directly placed 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 to slide smoothly into the conveying track 2, avoiding the material box 9 from getting stuck at the entrance. The inclined 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. A plurality of support frames 14 are arranged, 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 joint track 17 and a lap joint cylinder 18. The mounting seat 16 is supported and arranged 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 joint track 17 is rotatably hinged with the mounting seat 16, and the lap joint cylinder 18 is The hinge is set on the mounting seat 16, and the piston rod end of the lap cylinder 18 is movably hinged with the lap track 17. The lap track 17 includes a lap track 1 20 and a lap track 2 21. The lap track 1 20 and the lap track 2 21 are fixedly connected by a connecting rod 19. The piston rod of the lap cylinder 18 is extended and retracted to drive the lap track 17 to rotate and adjust. When the lap track 17 is rotated into place, the lap track 1 20 is overlapped and connected with the track line 1 6, and the lap track 2 21 is overlapped and connected with the track line 2 7. The alignment connection between the conveying track 2 and the track 40 in the vacuum cooler is realized by the lap track 17, which ensures the continuity and stability of the material box 9 during the transmission process and improves the efficiency and reliability of material transmission. The overlapping track 17 realizes automatic angle adjustment through the overlapping cylinder 18, and 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 inner track 40 of the vacuum cooler. However, if there is a height difference between the conveying track 2 and the inner track 40 of the vacuum cooler, 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 inner track 40 of the vacuum cooler with different height differences, thereby increasing the flexibility and reliability of the system.

[0025] The conveyor chain device 4 includes a driving motor 22, a driving sprocket 23, a driving spindle 24 and a conveyor chain assembly. The motor shaft of the driving motor 22 is connected to the driving sprocket 23. A transmission sprocket 25 is provided on the driving spindle 24. A transmission chain (not shown in the figure) is connected between the transmission sprocket 25 and the driving 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 driving 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 conveying chain assemblies, thereby driving the synchronous operation of the two conveying chain assemblies to ensure the smooth and reliable operation of the entire conveying chain device 4. The conveying chain is driven to rotate by the active sprocket 26, and the two conveying chains are connected to the pushing device 3, so that the pushing device 3 is driven by the conveying 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 rack 28, a pushing roller 29, a connecting rod 30 and an adjusting cylinder 31. The pushing rack 28 is horizontally mounted on the frame 1. A sliding block 32 is provided at the bottom end of the pushing rack 28. The sliding block 32 is slidably connected to the frame 1. The adjusting cylinder 31 and the connecting rod 30 are hingedly arranged on the pushing rack 28. Connecting rods 30 and adjusting cylinders 31 are provided on both sides of the pushing rack 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 and arranged between the two connecting rods 30. A connecting screw 33 is provided on the pushing rack 28. The connecting screw 33 is fixedly mounted on the sliding block 32. The connection and fixation between the pushing rack 28 and the conveying chain are realized by the connecting screw 33. The push rack 28 is slidably connected to the frame 1 through the sliding block 32, so that the push rack 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 push rack 28 during the sliding process, making the sliding smoother. At the same time, the guide pulley can also ensure the stability of the push rack 28 during the sliding process to avoid deviation or shaking. When the push 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 push rack 28, so that when the conveying chain moves, The pushing rack 28 will also move accordingly to ensure the synchronization between the pushing device 3 and the conveying chain device 4, so as to ensure 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 conveying chain device 4 drives the pushing device 3 to move and reset. By adjusting the angle of the pushing roller 29, the pushing roller 29 will not interfere with the unloaded material box 9 on the conveying track 2 during the resetting 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 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 conveying chain. The chain support 34 is arranged along the length direction of the frame 1, and stably supports and guides the conveying chain, so that the conveying chain can move along a predetermined path, prevents the conveying chain from deviating or falling off, and helps to improve the conveying efficiency and ensure the continuous operation of the system. In actual installation, the chain support 34 can be installed at one of the conveying chains, or at both conveying chains. A limit rod 35 is arranged below the connecting rod 30, and a limit support surface 36 is arranged at the end of the limit rod 35. The limit rod 35 is fixedly connected to the pusher frame 28, and the limit rod 35 provides stable support for the connecting rod 30 after it is rotated down to its position, so as to prevent the pusher roller 29 from deviating or shaking during the pushing process, so that the pusher roller 29 is 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 cleverly designed and easy to use. The feeding and discharging system can assist the material box 9 to be fed into and out of the vacuum cooling machine 39, thereby effectively improving the efficiency of loading and unloading, and ensuring the accuracy of loading and unloading. The whole system is simple to operate. It only needs to place the material box 9 on the conveying track 2. The system then drives the pushing device 3 to move through the conveying chain device 4 to realize the automatic pushing and conveying process. The degree of automation is high, which effectively reduces labor costs and improves production efficiency. The conveying track 2 defines 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 to realize the smooth and rapid movement of the material box 9, thereby effectively improving production efficiency. A lap joint device 5 is set between the conveying track 2 and the vacuum cooling machine 39. The lap joint device 5 realizes the lap connection between the conveying track 2 and the inner track 40 of the vacuum cooling machine, ensuring that the material can smoothly and seamlessly transition from the conveying track 2 to the inside of the vacuum cooling machine 39, avoiding the risk of tilting, tipping, etc. of the material box 9 during the transfer process, and improving the stability and safety of the operation of the whole system. 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 also be pushed out from the exit end of the track 40 in the vacuum cooler at the same time. The pushed out material boxes 9 are guided and slide 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.
