Description

Technical Field

[0001] The present invention relates to the technology of industrial food processing, and specifically to an intelligent suspension conveying system for food sterilization. Background Art

[0002] As is known, in the process of industrial food processing, sterilization operation is crucial to ensure food safety and extend the shelf life of food. Food is extremely vulnerable to microbial contamination during production, processing, storage, and transportation. Without effective sterilization treatment, it will lead to food spoilage, reduced nutritional value, and even endanger the health of consumers. Therefore, efficient and reliable food sterilization technologies and equipment are key requirements for industrial food production.

[0003] The deficiencies of the prior art are that in some traditional systems, when food is conveyed to the sterilization area, it is often simply conveyed linearly through the sterilization equipment. In this way, only part of the surface of the food can fully contact the sterilization environment during the sterilization process, making it difficult to achieve comprehensive and uniform sterilization of all parts of the food, resulting in incomplete sterilization of some areas of the food, affecting the quality and safety of the food, and unable to meet the strict requirements for sterilization effects in industrial food production. Even if a rotatable hanging sterilization structure is set, the hanging sterilization in the industrial food production process is a continuous process. When setting a continuously rotating hook, when the sterilization frame needs to be hung on the hook, the connection between the continuously rotating hook and the sterilization frame is prone to connection errors, resulting in the sterilization frame being unable to be hung, and a large number of sterilization frames that cannot be hung on the hook will accumulate at the feeding point during the sterilization process, affecting the efficiency of industrial food production. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent suspension conveying system for food sterilization to solve the above deficiencies in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: including: a food sterilization conveyor, in the middle section of the food sterilization conveyor, there is an intelligent sterilizer for sterilizing food, and further including:

[0006] A rotating gear, the bottom of the rotating gear is connected to a hook through a transmission rod;

[0007] A rotating rack, the rotating rack is arranged at the bottom of the inner side walls of the conveying track;

[0008] The switching mechanism is drivingly connected to the hook. When the sterilization frame is not hung on the hook, the rotating gear is located at the inner top of the conveying track and moves with the movement of the hook. After the sterilization frame is hung on the hook, the gravity of the sterilization frame is used to passively slide the rotating gear downward in the conveying track and engage with the rotating rack at a fixed position, and passively drive the hook to rotate uniformly for sterilization during the uniform conveying process by engaging with the rotating gear. After the sterilization frame is removed, the rotating gear and the rotating rack are passively separated again through the switching mechanism to fix and move the hook.

[0009] As a further description of the above technical solution: A closed conveying track is provided at the inner top of the food sterilization conveyor. The inside of the conveying track is cavity-shaped and an opening is provided in the middle of the bottom. Transmission chains are installed on both sides of the opening at the bottom inside the conveying track and are drivingly connected to the hook. Rotating racks are fixedly installed at the bottoms of both side walls inside the conveying track and are detachably engaged with the rotating gear.

[0010] As a further description of the above technical solution: The top position of the rotating rack is set to be conical, and the tip is upward.

[0011] As a further description of the above technical solution: One end of the driving rod is fixedly connected to the top of the hook, the other end of the driving rod is fixedly connected to the rotating gear, the driving rod is movably inserted into the center position of the fixed disk, transmission strips are provided on both sides of the fixed disk, and the transmission strips are drivingly connected to the transmission chain to drive the hook to slide uniformly.

[0012] As a further description of the above technical solution: The switching mechanism includes a sliding disk fixedly connected to the top of the driving rod. An insertion ring is fixedly connected to the outer circle of the bottom of the sliding disk. The insertion ring is slidably inserted into the slot. The slot is opened in the rotating sleeve. The rotating sleeve is fixedly installed on the surface of the fixed disk. A magnetic ring is fixedly connected to the bottom of the insertion ring. A magnetic ring is movably installed at the bottom inside the slot. The four corners of the bottom of the magnetic ring are connected to the bottom inside the slot through return springs.

[0013] As a further description of the above technical solution: The magnetic poles of the opposite end faces of the two magnetic rings are the same.

[0014] As a further description of the above technical solution: The switching mechanism further includes folding grooves opened on both side walls at the bottom inside the slot. The bottom end inside the folding groove is connected to the bottom end of the magnetic card through a tension spring. The top end of the magnetic card is slidably inserted into the folding groove.

[0015] As a further description of the above technical solution: The magnetic property of the end face of the magnetic card inserted into the slot is opposite to that of both sides of the bottom end of the magnetic ring at the bottom inside the slot.

[0016] As a further description of the above technical solution: a hanging ring detachably connected to the hook is provided above the sterilization frame.

[0017] As a further description of the above technical solution: the feeding end of the food sterilization conveyor is provided with a feeding belt, which transports the sterilization frame to the feeding end of the food sterilization conveyor and connects it between the hooks and then transports it to the intelligent sterilizer for sterilization.

[0018] In the above technical solution, the intelligent suspension conveying system for food sterilization provided by the present invention has the following beneficial effects:

[0019] 1. Improve the sterilization effect: After the sterilization frame is hung on the hook, the gravity of the sterilization frame causes the rotating gear to slide down and engage with the rotating rack, driving the hook to rotate at a uniform speed during the uniform speed conveying process to sterilize, so that the food around the sterilization frame can be sterilized repeatedly, ensuring that all parts of the food can be fully sterilized, thereby improving the overall sterilization effect.

[0020] 2. Ensure stable operation of the equipment: The two sets of magnetic rings in the switching mechanism repel each other with the same poles, and the magnetic card cooperates with the magnetic ring to reduce the bumps of the plug ring caused by the elastic potential energy of the reset spring, avoid the sterilization frame suspended by the hook from shaking up and down, and make the sterilization frame more stable when rotating and moving in the intelligent sterilizer for sterilization.

[0021] 3. Facilitate the recycling of equipment: After the sterilization is completed and the sterilization frame is removed, the switching mechanism can separate the rotating gear from the rotating rack and stop the rotation of the hook, making it convenient for the subsequent hook to hang a new sterilization frame, thereby realizing the recycling and efficient use of the equipment.

[0022] 4. Optimize the meshing of gears and racks: The top of the rotating rack is conical and the tip is facing upward. Even if the rotating gear teeth conflict with the rotating rack teeth, when the transmission chain drives the hook to move, the rotating gear teeth can slide down along both sides of the tip of the rotating rack teeth to a suitable position to achieve better meshing rotation.

An insertion ring 16 is fixedly connected to the outer circle of the bottom of the sliding disk 11. The insertion ring 16 is slidably inserted into the slot 17. The slot 17 is opened in the rotating sleeve 13. The rotating sleeve 13 is fixedly installed on the surface of the fixed disk 14. A magnetic ring 20 is fixedly connected to the bottom of the insertion ring 16. A magnetic ring 20 is movably installed at the bottom of the slot 17. The four corners of the bottom of the magnetic ring 20 are connected to the bottom of the slot 17 through a return spring 18.

[0042] In yet another embodiment provided by the present invention, the switching mechanism further includes folding grooves 22 opened on both side walls at the bottom of the slot 17. The bottom end of the folding groove 22 is connected to the bottom end of the magnetic card 21 through a tension spring 23. The top end of the magnetic card 21 is slidably inserted into the folding groove 22.

[0043] In yet another embodiment provided by the present invention, a closed conveying track 10 is provided at the inner top of the food sterilization conveyor 1. The inside of the conveying track 10 is cavity-shaped and an opening is provided in the middle of the bottom. Transmission chains 8 are installed on both sides of the opening at the bottom of the conveying track 10 and are drivingly connected to the hook 4. Rotating racks 9 are fixedly installed at the bottom of both side walls of the conveying track 10 and are detachably meshingly connected to the rotating gear 7.

[0044] In yet another embodiment provided by the present invention, one end of the transmission rod 12 is fixedly connected to the top end of the hook 4, the other end of the transmission rod 12 is fixedly connected to the rotating gear 7, the transmission rod 12 is movably inserted into the central position of the fixed disk 14, and transmission strips 15 are provided on both sides of the fixed disk 14. The transmission strips 15 are drivingly connected to the transmission chains 8 to drive the hook 4 to slide at a constant speed.

[0045] In yet another embodiment provided by the present invention, the top of the rotating rack 9 is conical and the tip faces upward.

[0046] In yet another embodiment provided by the present invention, the magnetic poles of the end faces corresponding to each other of the two magnetic rings 20 are the same.

[0047] In yet another embodiment provided by the present invention, preferably, the magnetic poles of the end face of the magnetic card 21 inserted in the slot 17 and the two sides at the bottom end of the magnetic ring 20 at the inner bottom of the slot 17 are opposite.

[0048] During the industrial production process of food, for the disinfection operation of food, generally the food is placed in the intelligent sterilizer 2 for sterilization. After the food to be sterilized is placed in the sterilization frame 5 and then placed on the feeding belt 3, the feeding belt 3 conveys the sterilization frame 5 to the feeding end position of the food sterilization conveyor 1. Then, the movement of the transmission chain 8 at the top of the food sterilization conveyor 1 drives the hook 4 to move at a constant speed inside the food sterilization conveyor 1. When the hook 4 moves to the feeding end position, the hook 4 hooks into the hanging ring 6 provided above the sterilization frame 5. Then, the hook 4 can lift the sterilization frame 5 through the hanging ring 6. And after the sterilization frame 5 is separated from the feeding belt 3, the hook 4 hangs the sterilization frame 5 and drives the sterilization frame 5 to be conveyed into the intelligent sterilizer 2, so as to sterilize the food in the sterilization frame 5;

[0049] The meshing connection between the transmission chain 8, the fixed disk 14 and the transmission bar 15 drives the uniform movement of the hook 4. This is prior art and will not be elaborated here.

[0050] After the hook 4 is connected to the hanging ring 6, at this time the sterilization frame 5 has not been separated from the feeding belt 3 yet, and the feeding belt 3 has not exerted a downward pulling force on the hook 4. At the same time, the sterilization frame 5 moves synchronously with the hook 4 along with the conveyance of the feeding belt 3. At this time, the rotating gear 7 connected to the top of the hook 4 is misaligned with the rotating rack 9. And due to its own gravity, the hook 4 meshes the transmission bars 15 provided on both sides of the fixed disk 14 with the transmission chain 8 provided at the bottom in the conveying track 10, so that the hook 4 moves along with the movement of the transmission chain 8. And the meshing connection between the transmission chain 8 and the rack at the bottom of the transmission bar 15, combined with the gravity of the hook 4 itself, can fix the position of the hook 4;

[0051] After the sterilization frame 5 falls off the feeding belt 3, at this time there is no load-bearing at the bottom of the sterilization frame 5. Due to its own weight and the weight of the food placed inside, the sterilization frame 5 pulls the hook 4 downward. During the pulling process:

[0052] The sterilization frame 5 pulls the hook 4 downward through the hanging ring 6, and the hook 4 drops downward and pulls the rotating gear 7 fixed at the top through the transmission rod 12 to move downward in the conveying track 10, and slides the rotating gear 7 downward from the position above the conveying track 10 to the position of the rotating rack 9, so that the rotating gear 7 is meshed and connected with the rotating rack 9, so that when the transmission chain 8 drives the hook 4 to move through the transmission bar 15 and the fixed plate 14, the transmission chain 8 drives the movement of the hook 4 due to the fixed position of the rotating rack 9, so that the rotating gear 7 is rotated after being subjected to force on the surface of the rotating rack 9, so that the hook 4 is slowly rotated in the intelligent sterilizer 2, thereby driving the sterilization frame 5 to rotate during the sterilization process in the intelligent sterilizer 2, so that the food around the sterilization frame 5 can be repeatedly sterilized;

[0053] It should be noted here that the top position of the rotating rack 9 is set to be conical, and the tip is facing upward, which can ensure that when the hook 4 pulls the rotating gear 7 downward, even if the latching teeth on the rotating gear 7 conflict with the latching teeth of the rotating rack 9, as the rotation of the transmission chain 8 drives the hook 4 to move, the latching teeth of the rotating gear 7 will slide downward along both sides of the tip of the top of the latching teeth of the rotating rack 9 to the position between the latching teeth of the rotating rack 9, so as to better mesh and rotate the rotating gear 7 with the rotating latching teeth;

[0054] During the descending process of the rotating gear 7, since the fixed disk 14 is tightly fitted with the inner wall of the bottom of the conveying track 10, the hook 4 will only drive the rotating gear 7 to slide downward through the transmission rod 12, and at the same time, the sliding disk 11 fixedly set on the top surface of the transmission rod 12 below the rotating gear 7 drives the plug ring 16 set at the bottom to slide downward and be inserted into the plug sleeve, and the plug sleeve is set on the surface of the fixed disk 14, and a slot 17 with an opening from the top is opened inside, and a magnetic card 21 connected by a tension spring 23 is opened in the folding groove 22 symmetrically recessed inwardly on the two side walls around the bottom of the slot 17, and the bottom of the slot 17 is fixedly connected to the reset spring 18 and a group of magnetic rings 20, and the width of the magnetic ring 20 is adapted to the inner diameter of the slot 17 to ensure that the magnetic ring 20 can slide up and down in the slot 17, and a group of magnetic rings 20 is also set at the bottom of the plug ring 16, and the magnetism between the corresponding end faces of the two groups of magnetic rings 20 is the same;

[0055] As the plug ring 16 is gradually inserted into the slot 17, the magnetic ring 20 at the bottom of the plug ring 16 will also be inserted into the bottom of the slot 17, and the end face of the magnetic ring 20 connected to the bottom of the slot 17 through the reset spring 18 will be resisted by the end face of the upper magnetic ring 20 due to the same magnetic pole, so that the magnetic ring 20 at the bottom of the slot 17 slides downward and squeezes the reset spring 18. When the sterilization frame 5 drives the hook 4 to drop to the limit position, the other magnetic pole at the bottom of the magnetic ring 20 installed at the bottom of the slot 17 is opposite to the magnetic end face of the magnetic card 21 set in the folding groove 22, and the bottom of the magnetic ring 20 reaches the opening position of the folding groove 22. The magnetic card 21 is sucked out of the folding groove 22 and the tension spring 23 is pulled by the mutual attraction characteristics of different magnetic poles.

[0056] It should be noted here that the magnetic attraction between the magnetic ring 20 and the magnetic card 21 is greater than the rebound force generated when the magnetic card pops out of the folding groove 22 and the magnetic ring 20 is pulled against the extension spring 23;

[0057] At this time, the magnetic card is inserted into the gaps on both sides of the reset spring 18, resulting in the upward rebound force of the reset spring 18 at the bottom of the magnetic card acting on the magnetic card, but unable to be transmitted to the magnetic ring 20 above. Only the rebound force of one end of the reset spring 18 above the magnetic card acts on the magnetic ring 20, which can reduce the elastic potential energy of the reset spring 18, causing the insert ring 16 to bump up and down in the slot 17, resulting in the sterilization frame 5 suspended by the hook 4 also bumping up and down. At the same time, the magnetic interference between the two groups of magnetic rings 20 is relatively stable, so only a relatively small rebound force of the reset spring 18 is directed to the magnetic ring 20, and when the hook 4 rotates, the magnetic ring 20 set at the bottom of the plug ring 16 will also rotate in the slot 17, and the plug ring 16 is limited by the size of the slot 17, and will not shake left and right, while the shaking of the upper and lower amplitudes is stabilized by the two groups of magnetic rings 20, thereby improving the stability of the sterilization frame 5 when rotating and moving in the intelligent sterilizer 2 for sterilization;

[0058] The section of the return spring 18 above the magnetic card 21 also has a special effect in resetting the hook 4:

[0059] After the food sterilization in the sterilization frame 5 is completed, after removing the hanging ring 6 at the top of the sterilization frame 5 from the hanging hook 4, in order to recycle the hanging sterilization frame 5 on the subsequent hanging hook 4, the rotating hanging hook 4 is not convenient for hanging the hanging ring 6. Therefore, it is necessary to separate the rotating gear 7 at the top of the hanging hook 4 from the rotating rack 9. At this time, the hanging hook 4 loses the action of the gravity of the sterilization frame 5 and the food. At this time, due to the restriction of the magnetic card 21 on the return spring 18, the magnetic ring 20 at the bottom of the folding groove 22 cannot pop up upward, and the magnetic column at the bottom of the insertion ring 16 cannot be repelled and slid upward. At this time, in order to restore the hanging hook 4 upward, the section of the return spring 18 located above and stuck by the magnetic card 21 can play a role. At this time, the return spring 18 above the magnetic card 21 rebounds and resets upward after losing the extrusion of the magnetic ring 20 driven by gravity, thereby lifting the magnetic ring 20 upward and raising the position of the bottom end of the magnetic ring 20 to separate from the magnetic card 21 adsorbed magnetically on both sides. After the bottom end of the magnetic ring 20 is separated from the magnetic card 21, the magnetism adsorbed between the magnetic ring 20 and the magnetic card 21 disappears, and the magnetic card 21 is pulled by the tension spring 23 at the bottom end and contracts into the folding groove 22. At this time, the return spring 18 loses the restriction of the magnetic card 21 and can completely transmit the rebounding force to the magnetic ring 20. The magnetic ring 20 at the bottom of the slot 17 slides upward, and at the same time, the magnetic ring 20 at the bottom end of the insertion ring 16 drives the insertion ring 16 and the sliding disk 11 to slide upward along with the magnetic repulsion force, thereby separating the rotating gear 7 from the rotating rack 9, and the rotation of the hanging hook 4 can be stopped;

[0060] It should be noted here that the resilience of the return spring 18 rebounding upward is less than the pulling force of the tension spring 23 on the magnetic card 21. Therefore, when the upward resilience of the return spring 18 acts on the magnetic card 21, the tension spring 23 can still pull the magnetic card 21 back into the folding groove 22 and contract.

[0061] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
