Description

TECHNICAL FIELD

[0001] The present application relates to food industrial processing technology, in particular to an intelligent suspension conveying system for food sterilization. BACKGROUND

[0002] It is known that, in the process of food industrialization, sterilization operation is crucial to ensure food safety and extend the shelf life. Food is easily contaminated by microorganisms during production, processing, storage and transportation. If effective sterilization is not performed, food will deteriorate, nutritional value will decrease, and even harm consumer health. Therefore, efficient and reliable food sterilization technology and equipment are key requirements for food industrialization.

[0003] The deficiency of the prior art is that in some traditional systems, when food is conveyed to the sterilization area, it is only simply linearly conveyed through the sterilization equipment. This way makes only part of the surface of the food fully contact the sterilization environment during sterilization, making it difficult to achieve comprehensive and uniform sterilization of all parts of the food. This results in incomplete sterilization of some areas of the food, affecting food quality and safety, and failing to meet the strict requirements of food industrialization for sterilization effect. Even if a rotatable suspension sterilization structure is provided, the suspension sterilization in the process of food industrialization is a continuous process. The setting of a continuously rotating hook makes it easy to connect the sterilization frame to the hook, which can cause the sterilization frame to fail to be hung and cause a large number of sterilization frames to accumulate at the feeding point during the sterilization process, affecting the efficiency of food industrialization. SUMMARY

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

[0005] In order to achieve the above-mentioned purpose, the present application provides the following technical solution: comprising: a food sterilization conveyor, an intelligent sterilization machine for sterilizing food is arranged in the middle section of the food sterilization conveyor, further comprising:

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

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

[0008] The switching mechanism is in transmission connection with the hook. When the sterilization frame is not hung on the hook, the rotating gear moves in the top of the conveying track and moves with the hook. After the sterilization frame is hung on the hook, the rotating gear is passively slid downward in the conveying track by the gravity of the sterilization frame and is engaged between the rotating racks in the fixed position. The hook is passively driven to rotate at a constant speed during the uniform conveying process through the engagement of the hook and the rotating gear. After the sterilization frame is removed, the rotating gear is separated from the rotating racks through the switching mechanism, and the movement of the hook is fixed.

[0009] As a further description of the above technical solution: the conveying track is provided in the top of the food sterilization conveyor in a closed manner. The conveying track is in a cavity shape and has an opening in the middle of the bottom. The transmission chain is installed on both sides of the opening in the bottom of the conveying track and is in transmission connection with the hook. The rotating racks are fixedly installed on the bottom of the two side walls in the conveying track and are in separable engagement with the rotating gear.

[0010] As a further description of the above technical solution: the top of the rotating rack is provided in a tapered shape, and the tip is upward.

[0011] As a further description of the above technical solution: the top end of the hook is fixedly connected to one end of the transmission rod. The other end of the transmission rod is fixedly connected to the rotating gear. The transmission rod is movably inserted into the center of the fixed disc. The transmission bars are provided on both sides of the fixed disc. The transmission bars are in transmission connection with the transmission chain, thereby driving the uniform sliding of the hook.

[0012] As a further description of the above technical solution: the switching mechanism includes a sliding disc fixedly connected to the top end of the transmission rod. The sliding disc is fixedly connected to the insertion ring at the bottom. The insertion ring is slidably inserted into the insertion slot. The insertion slot is provided in the rotating sleeve. The rotating sleeve is fixedly installed on the surface of the fixed disc. The insertion ring is fixedly connected to the magnetic ring at the bottom. The magnetic ring is movably installed in the bottom of the insertion slot. The magnetic ring is connected to the bottom of the insertion slot through the return spring at the bottom of the four corners.

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

[0014] As a further description of the above technical solution: the switching mechanism further includes the folding grooves provided on the two side walls of the bottom of the insertion slot. The bottom end of the folding groove is connected to the bottom end of the magnetic card through the 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 end face of the magnetic card inserted into the insertion slot and the magnetic ring at the bottom of the insertion slot on both sides of the bottom end are opposite in magnetic property.

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

[0017] As a further description of the above technical solution: the food sterilization conveyor is provided with a feeding belt at the feeding end, and the sterilization frame is conveyed into the intelligent sterilization machine after being connected between the hooks.

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

[0019] 1. Improve sterilization effect: after the hooks suspend the sterilization frame, the gravity of the sterilization frame makes the rotating gear slide down and engage with the rotating rack, driving the hooks to rotate at a uniform speed during uniform conveying, which can repeatedly sterilize the food around the sterilization frame, ensuring that all parts of the food are fully sterilized and improving the overall sterilization effect.

[0020] 2. Ensure stable operation of the equipment: the two groups of magnetic rings in the switching mechanism repel each other, and the magnetic card cooperates with the magnetic ring to reduce the rocking of the inserted ring caused by the elastic potential energy of the return spring, avoiding the sterilization frame suspended by the hooks from shaking up and down greatly, making the sterilization frame more stable when rotating and moving in the intelligent sterilization machine.

[0021] 3. Facilitate the recycling of the equipment: after the sterilization is completed and the sterilization frame is removed, the switching mechanism can separate the rotating gear from the rotating rack, stopping the rotation of the hooks, facilitating the suspension of new sterilization frames by the subsequent hooks, and realizing the recycling and efficient use of the equipment.

[0022] 4. Optimize the engagement of the gear and rack: the top of the rotating rack is tapered and the tip is upward, so even if the rotating gear teeth and the rotating rack teeth resist each other, the rotating gear teeth can slide down along the sides of the rotating rack teeth tips to the appropriate position when the transmission chain drives the hooks to move, achieving better engagement and rotation.

[0039] In still another embodiment of the present application, preferably, a hanging ring 6 detachably connected with the hook 4 is arranged above the sterilization frame 5.

[0041] In still another embodiment of the present application, the switching mechanism comprises a sliding disc 11 fixedly connected to the top end of a transmission rod 12, an insertion ring 16 fixedly connected to the bottom outer ring of the sliding disc 11, the insertion ring 16 being slidably inserted into an insertion slot 17, the insertion slot 17 being arranged in a rotating sleeve 13, the rotating sleeve 13 being fixedly installed on the surface of a fixed disc 14, a magnetic ring 20 being fixedly connected to the bottom of the insertion ring 16, the magnetic ring 20 being movably installed at the bottom of the insertion slot 17, and the bottom of the magnetic ring 20 being connected to the bottom of the insertion slot 17 through a return spring 18.

[0043] In still another embodiment of the present application, the top of the food sterilization conveyor 1 is provided with a closed conveying track 10, the conveying track 10 is in a hollow shape and has an opening arranged in the middle of the bottom, transmission chains 8 are installed on both sides of the bottom opening of the conveying track 10 and are in transmission connection with the hooks 4, and rotating racks 9 are fixedly installed on the bottom of the two side walls of the conveying track 10 and are in separable engagement connection with the rotating gears 7.

[0044] In still another embodiment of the present application, the top end of the hook 4 is fixedly connected to one end of the transmission rod 12, 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 center position of the fixed disc 14, transmission bars 15 are arranged on both sides of the fixed disc 14, the transmission bars 15 are in transmission connection with the transmission chains 8, and the uniform sliding of the hook 4 is driven.

[0045] In another embodiment of the present application, the top of the rotating rack 9 is tapered, and the tip is upward.

[0046] In another embodiment of the present application, the magnetic poles of the corresponding end faces of the two groups of magnetic rings 20 are the same.

[0047] In another embodiment of the present application, preferably, the end face of the magnetic card 21 inserted into the slot 17 is opposite to the magnetic force on both sides of the bottom end of the magnetic ring 20 at the bottom of the slot 17.

[0048] In the industrial production process of food, in order to disinfect the food, the food is placed in the intelligent sterilization machine 2 for sterilization, and 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. The top of the food sterilization conveyor 1 drives the hook 4 to move uniformly in the food sterilization conveyor 1 through the movement of the transmission chain 8. When the hook 4 moves to the feeding end position, the hook 4 is hung in the hanging ring 6 arranged above the sterilization frame 5, and the hook 4 can lift the sterilization frame 5 through the hanging ring 6. After the sterilization frame 5 is separated from the feeding belt 3, the hook 4 suspends the sterilization frame 5 and drives the sterilization frame 5 to be conveyed to the inside of the intelligent sterilization machine 2, so as to sterilize the food in the sterilization frame 5.

[0049] The engagement connection between the transmission chain 8, the fixed disc 14 and the transmission bar 15 drives the uniform movement of the hook 4. The prior art is not shown here, and will not be described in detail here.

[0050] After the hook 4 is connected with the hanging ring 6, the sterilization frame 5 has not been separated from the feeding belt 3, and the feeding belt 3 has not generated a downward pulling force on the hook 4. At the same time, the sterilization frame 5 moves synchronously with the hook 4 between the feeding belt 3 and the hook 4. At this time, the top end of the hook 4 connected with the rotating gear 7 is misaligned with the rotating rack 9, and the transmission bar 15 arranged on both sides of the fixed disc 14 is engaged and connected between the transmission chain 8 arranged at the bottom and the conveying track 10, so as to move the hook 4 with the transmission chain 8. The engagement connection between the transmission chain 8 and the transmission bar 15 at the bottom of the rack can fix the position of the hook 4 in cooperation with the gravity of the hook 4 itself.

[0051] After the sterilization frame 5 falls off from the feeding belt 3, the sterilization frame 5 is pulled downward by its own weight and the weight of the food placed inside during the pulling process:

[0052] The sterilization frame 5 pulls the hook 4 downwards via the hanging ring 6. The hook 4 descends and pulls the rotating gear 7, which is fixedly connected to the top, downwards within the conveying track 10 via the transmission rod 12. The rotating gear 7 slides down from the position above the conveying track 10 to the position of the rotating rack 9, thereby meshing and connecting the rotating gear 7 and the rotating rack 9. Thus, while the transmission chain 8 drives the hook 4 to move through the transmission bar 15 and the fixed plate 14, the fixed position of the rotating rack 9 causes the transmission chain 8 to drive the hook 4 to move. Therefore, the rotating gear 7 rotates after being subjected to force on the surface of the rotating rack 9, thereby slowly rotating the hook 4 within the intelligent sterilizer 2. This causes the sterilization frame 5 to rotate during the sterilization process within the intelligent sterilizer 2, enabling repeated sterilization of the food around the perimeter of the sterilization frame 5.

[0053] It should be noted here that the top of the rotating rack 9 is set in a conical shape with the tip pointing upwards. This ensures that when the hook 4 pulls the rotating gear 7 downwards, even if the teeth on the rotating gear 7 are in contact with the teeth on the rotating rack 9, as the transmission chain 8 rotates and drives the hook 4 to move, the teeth on the rotating gear 7 will slide downwards along both sides of the tip of the teeth on the rotating rack 9 to the position between the teeth on the rotating rack 9, thereby better meshing and rotating the rotating gear 7 with the rotating teeth.

[0054] During the descent of the rotating gear 7, since the fixed plate 14 and the inner wall of the bottom of the conveying track 10 are tightly fitted, the hook 4 will only drive the rotating gear 7 to slide downward through the transmission rod 12. At the same time, the sliding plate 11 fixedly set on the top surface of the transmission rod 12 below the rotating gear 7 will drive the bottom-set insert ring 16 to slide downward and insert into the insert sleeve. The insert sleeve is set on the surface of the fixed plate 14 and has a slot 17 with an open top inside. The magnetic card 21 is connected by a tension spring 23 in the folding groove 22 symmetrically recessed inward on the two side walls around the bottom of the slot 17. The bottom of the slot 17 is fixedly connected to a reset spring 18 and a set of magnetic rings 20. The width of the magnetic rings 20 is adapted to the inner diameter of the slot 17 to ensure that the magnetic rings 20 can slide up and down in the slot 17. The bottom of the insert ring 16 is also set with a set of magnetic rings 20, and the magnetism between the corresponding end faces of the two sets of magnetic rings 20 is the same.

[0055] When the ring 16 is gradually inserted into the slot 17, the magnetic ring 20 at the bottom of the ring 16 is also gradually inserted into the bottom of the slot 17. The end face of the magnetic ring 20 at the bottom of the slot 17 connected by the return spring 18 is resisted by the end face of the upper magnetic ring 20 due to the same magnetic poles, which slides the magnetic ring 20 at the bottom of the slot 17 downward and compresses the return spring 18. When the hanger 4 is lowered to the limit position by the sterilization frame 5, the other magnetic pole end at the bottom of the magnetic ring 20 at the bottom of the slot 17 is opposite to the end face of the magnetic card 21 arranged in the folding groove 22 in terms of magnetism, and the bottom of the magnetic ring 20 reaches the opening position of the folding groove 22 at this time. The magnetic card 21 is attracted out of the folding groove 22 and pulls the extension spring 23 by using the characteristics of different magnetic poles attracting each other;

[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 is pulled out of the folding groove 22 and connected to the magnetic ring 20;

[0057] At this time, the magnetic card is inserted into the gap between the two sides of the return spring 18, causing the return spring 18 at the bottom of the magnetic card to rebound upward and act on the magnetic card, and the rebound force of only one end of the return spring 18 above the magnetic card can act on the magnetic ring 20, which can reduce the large up-and-down oscillation of the ring 16 in the slot 17 caused by the elastic potential energy of the return spring 18, causing the hanger 4 to also oscillate greatly up and down, and the magnetic resistance between the two groups of magnetic rings 20 is relatively stable. Therefore, only the rebound force of the return spring 18 with a smaller amplitude is conducted to the magnetic ring 20, and when the hanger 4 rotates, the magnetic ring 20 at the bottom of the ring 16 also rotates in the slot 17, and the ring 16 is limited by the size of the slot 17 and does not shake left and right. The up-and-down amplitude of the shaking is stabilized by the two groups of magnetic rings 20, which improves the stability of the sterilization frame 5 rotating and moving in the intelligent sterilization machine 2 during sterilization;

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

[0059] After the sterilization of the food in the sterilization frame 5 is completed, the hanging ring 6 on the top of the sterilization frame 5 is taken off from the hook 4, in order to cycle use the hanging sterilization frame 5 on the subsequent hook 4, the rotating hook 4 is not convenient to hang the hanging ring 6, therefore, the rotating gear 7 at the top end of the hook 4 needs to be separated from the rotating rack 9, at this time, the hook 4 loses the gravity of the sterilization frame 5 and the food, at this time, the magnetic ring 20 at the bottom of the folding groove 22 cannot be popped up upward due to the limitation of the reset spring 18 by the magnetic card 21, and the magnetic column at the bottom of the plug ring 16 cannot be repulsed and slid upward, at this time, in order to restore the hook 4 upward, the reset spring 18 above the magnetic card 21 can play a role by being clamped by the magnetic card 21, at this time, the reset spring 18 above the magnetic card 21 is bounced back upward after losing the extrusion of the magnetic ring 20 driven by gravity, so as to lift the magnetic ring 20 upward, and the position of the bottom end of the magnetic ring 20 is separated from the magnetic card 21 on both sides, after the separation between the bottom end of the magnetic ring 20 and the magnetic card 21, the magnetic force between the magnetic ring 20 and the magnetic card 21 disappears, the magnetic card 21 is shrunk into the folding groove 22 by the stretching spring 23 at the bottom end, at this time, the reset spring 18 can completely transmit the rebound force to the magnetic ring 20 after losing the limitation of the magnetic card 21, the magnetic ring 20 at the bottom of the plug slot 17 slides upward at the same time, the magnetic ring 20 at the bottom end of the plug ring 16 repels the plug ring 16 and the sliding disc 11 with the transmission rod 12 upward by the magnetic repulsion force, so as to separate the rotating gear 7 from the rotating rack 9, and the rotation of the hook 4 is stopped.

[0060] It should be noted that the rebound force of the reset spring 18 upward is smaller than the stretching force of the stretching spring 23 to the magnetic card 21, therefore, when the rebound force of the reset spring 18 upward acts on the magnetic card 21, the stretching spring 23 can still pull the magnetic card 21 back to the folding groove 22 to be shrunk.

[0061] The above only describes some exemplary embodiments of the application in a descriptive manner, it is self-evident that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the application.
