Description

Technical Field

[0001] This invention relates to the field of sterilization equipment technology, specifically a sterilization device for processing wet pet food. Background Technology

[0002] The production process of canned food generally involves processing raw materials through canning, sealing, and sterilization. Wet pet food is typically stored in cans. After being sealed in cans, wet pet food undergoes sterilization to ensure long-term preservation.

[0003] Existing horizontal sterilization tanks typically place canned goods in a placement frame. During steam sterilization, because the cans are stacked together, the contact effect between the inner and outer cans and the steam is different, resulting in asynchronous sterilization of the canned goods as a whole and affecting the uniformity of the canned product quality.

[0004] For example, an existing sterilization pot for fish can production, with publication number CN219373709U, "includes a base, a pot body fixedly connected to the surface of the base, a movable groove a and a wheel groove opened on the bottom wall of the inner cavity of the pot, a bottom plate slidably connected to the bottom wall of the inner cavity of the pot, a threaded rod a rotatably connected to the inner side wall of the movable groove a, a threaded sleeve a threadedly connected to the surface of the threaded rod a, a movable block a fixedly connected to the surface of the threaded sleeve a and slidably connected to the movable groove a, the upper surface of the movable block a fixedly connected to the bottom surface of the bottom plate, a sterilization basket fixedly connected to the surface of the bottom plate, and a servo motor fixedly connected to the outer wall of the pot body and the power output end of the servo motor fixedly connected to one end of the threaded rod a." Although this patent uses a pressure plate to compress the cans during sterilization to prevent damage, the cans are still stacked together. The contact effect between the internal and external cans and the steam is different, resulting in asynchronous sterilization of the cans and affecting the uniformity of the canned product quality. Therefore, a new sterilization device for processing wet pet food is needed. Summary of the Invention

[0020] Beneficial effects

[0021] Compared with the prior art, the present invention provides a sterilization device for processing wet pet food, which has the following beneficial effects:

[0022] 1. Based on the diameter of the can, use a wrench to rotate the forward and reverse threaded rod to adjust the distance between the two moving frames of the same rotating clamping mechanism. Next, place several cans on each rotating placement frame, adjust the moving clamping assembly to the appropriate position to clamp the cans, that is, move the moving clamping assembly to the appropriate position, and then tighten the hand-tightening screw so that the hand-tightening screw presses against the moving seat, thus fixing the position of the moving seat. Thanks to the adjustable design of the rotating clamping mechanism, it can clamp cans of different diameters and quantities, improving the versatility of the sterilization device;

[0023] 2. Insert the horizontal frame of the rotating cylinder into the track, and then use the rotating frame mechanism to lock the position of the horizontal frame. That is, after the half ring of the rotating rod and the fixed half ring are vertically joined together, insert them. When the half ring of the rotating rod is inserted between the fixed half ring and the moving ring, rotate the rotating rod, and then release the rotating rod. Under the elastic force of the third spring, the fixed half ring and the moving ring clamp the half ring of the rotating rod. At the same time, the rotating rod is inserted into the insertion hole of the horizontal frame, so that the position of the horizontal frame is fixed. The locking mechanism is set to fix the horizontal frame, and the insertion seat coaxially fixedly connected to the rotating cylinder abuts against the connecting seat, so that the horizontal frame can be easily pulled out and installed, improving the convenience of can placement.

[0024] 3. Close the sealing cap, drive the motor to drive the first gear to rotate, the first gear drives the connecting seat to rotate through the second gear, the rotating connecting seat drives the rotating cylinder to rotate at low speed through the plug-in seat, causing several sets of rotating clamping mechanisms to rotate, and then the central nozzle sprays steam from the nozzle to sterilize the cans held on the rotating clamping mechanism at high temperature. Thanks to the low-speed rotation design of the cans, the central nozzle can sterilize each can at high temperature from multiple angles, reducing the sterilization dead angles of individual cans, and at the same time making the overall sterilization effect of the cans synchronized, improving the uniformity of the quality of canned products.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figure 1-14 A sterilization device for processing wet pet food includes a tank 1 and a sealing cap 8 that seals the opening of the tank 1. A vent pipe is connected to the top of the tank 1. A flange is provided at the top of the vent pipe for connecting to a pipe for discharging steam. A support frame 9 is fixedly connected to the bottom of the tank 1. Several through holes are provided on the bottom edge of the support frame 9 for bolts to pass through and fix it to the bottom surface. A central nozzle 2 passes through the center of the tank 1. The opening end of the central nozzle 2 is opposite to the opening end of the tank 1, and the central nozzle 2 is fixedly connected to the tank 1. A flange is provided at the opening of the central nozzle 2 for connecting to a pipe for input steam. The central nozzle 2 has several evenly distributed nozzles located within the inner cavity of the tank 1. A set of drive mechanisms 3 is fixedly installed at one end of the tank body 1, and the drive mechanism 3 is close to the opening end of the central nozzle 2. The drive mechanism 3 drives a set of rotating frame mechanisms 4 installed in the inner cavity of the tank body 1. The rotating frame mechanisms 4 are arranged in a ring with several evenly distributed rotating shafts. Each rotating shaft is rotatably mounted with a set of rotating clamping mechanisms 5, and the clamping mechanisms 5 are used to clamp the cans 7. The number of cans 7 clamped by each set of rotating clamping mechanisms 5 is as equal as possible, so that the rotating frame mechanisms 4 can operate stably.

[0048] The drive mechanism 3 includes: a drive motor 31 fixedly mounted on the outer wall of the tank 1, and a fixed seat 33 fixedly connected to the inner wall of the tank 1. A first gear 34 is coaxially fixedly sleeved at the output end of the drive motor 31. A first rotary bearing 35 is coaxially fixedly sleeved on the fixed seat 33. A second gear 36 is coaxially fixedly sleeved on the outer ring of the first rotary bearing 35. The second gear 36 meshes with the first gear 34, and a connecting seat 37 is coaxially fixedly connected to the second gear 36. A plug-in seat 38 is inserted into the connecting seat 37, and the plug-in seat 38 is coaxially fixedly connected to the rotating cylinder 45. When the drive motor 31 drives the first gear 34, the first gear 34 drives the connecting seat 37 to rotate via the second gear 36. A sealed bearing 32 is coaxially fixedly sleeved at the output end of the drive motor 31, and the sealed bearing 32 is embedded in the side wall of the tank 1. The plug-in seat 38 is provided with several annularly evenly distributed conical plugs, and the connecting seat 37 is provided with insertion holes adapted to the conical plugs. The conical inserts of the plug-in 38 are arranged in a tight ring, making it easy to insert the plug-in 38 into the connector 37. After the plug-in 38 and the connector 37 are coaxially inserted, the rotating connector 37 drives the rotating cylinder 45 to rotate at a low speed through the plug-in 38.

[0049] The rotating frame mechanism 4 includes: two tracks 41 fixedly connected to the inner wall of the tank 1; a horizontal frame 43 is slidably mounted on the two tracks 41; a rotating cylinder 45 is rotatably mounted at the center of the horizontal frame 43; and the rotating cylinder 45 has several evenly distributed rotating shafts arranged in a ring. The rotating shafts are used to rotatably connect to the rotating clamping mechanism 5. When the rotating cylinder 45 rotates, the rotating clamping mechanism 5 remains in a constant state under the action of gravity. Several linearly arranged rollers 42 are rotatably mounted in the grooves of each track 41, and each roller 42 is in rolling contact with the horizontal frame 43. The rollers 42 improve the smoothness of the movement of the horizontal frame 43 in the tracks 41. The horizontal frame 43 has rounded corners near the corners of the drive mechanism 3 to facilitate insertion into the tracks 41. The rounded corners of the horizontal frame 43 are asymmetrically designed. A second rotating bearing 44 is fixedly embedded in the circular rings at both ends of the horizontal frame 43, and the inner cavities of the two second rotating bearings 44 are coaxially fixedly connected to the rotating cylinder 45. The second rotary bearing 44 is used for the rotational connection between the horizontal frame 43 and the rotating cylinder 45.

[0050] Each set of rotating clamping mechanisms 5 includes: a rotating placement frame 51 rotatably mounted on the rotating shaft of the rotating cylinder 45; a mounting base 52 is fixedly mounted at each end of the rotating placement frame 51; two movable frames 53 are elastically slidably mounted on the two mounting bases 52, and the two movable frames 53 are symmetrically arranged about the rotating placement frame 51; a movable clamping assembly 55 is mounted on the two movable frames 53; and the two movable frames 53 and the movable clamping assembly 55 together clamp several linearly arranged cans 7 on the same rotating placement frame 51. A first spring 54 is fixedly connected to each end of each movable frame 53, and each first spring 54 is fixedly connected to the adjacent mounting base 52.

[0051] Each movable clamping assembly 55 includes: a movable base 551 whose bottom surface contacts the rotating placement frame 51; a slide rod 554 slidably mounted at both ends of the movable base 551, and a slider 553 fixedly connected to each slide rod 554; each slider 553 slidably connected to the movable frame 53; and a threaded rod 552 rotatably connected to the top of the movable base 551, with both ends of the threaded rod 552 threadedly connected to adjacent sliders 553. The threaded rod 552 is rotatably connected to the movable base 551 via bearings. A hexagonal nut is provided in the middle of the threaded rod 552; rotating the hexagonal nut with a wrench drives the two sliders 553 threadedly connected to the threaded rod 552 to move closer or separate, so that the two movable frames 53 slidably connected to the sliders 553 can move closer or separate. The distance between the two movable frames 53 is adjustable, allowing the rotating placement frame 51 to hold cans 7 of different diameters. A plurality of second springs 556 in a linear array are fixedly connected to the side of the movable seat 551 facing the can 7, and the plurality of second springs 556 are connected together to a stop plate 557 that presses against the can 7. The stop plate 557 elastically presses against the can 7 to prevent squeezing and damage to the can 7. A hand-tightening screw 555 is threadedly connected to the bottom of the movable seat 551 through a through groove at the bottom of the rotating placement frame 51. After tightening the hand-tightening screw 555, the hand-tightening screw 555 presses against the movable seat 551, so that the movable seat 551 is fixed in position. The position of the movable clamping assembly 55 is adjustable, so that the rotating clamping mechanism 5 can clamp different numbers of cans 7.

[0052] Each track 41 is equipped with a locking mechanism 6 at its end near the opening of the tank body 1. After the locking mechanism 6 locks the position of the horizontal frame 43, the insertion seat 38 is coaxially inserted into the connecting seat 37. Each locking mechanism 6 includes: a fixed half-ring 61 fixedly installed in the circular hole of the track 41, and a movable ring 62 slidably installed in the circular hole of the track 41. The fixed half-ring 61 is positioned above the movable ring 62. Several annularly distributed third springs 63 are fixedly connected to the bottom of the movable ring 62, and the bottom of each third spring 63 is fixedly connected to the track 41. A rotating rod 64 is inserted into the middle of the movable ring 62, and the half-ring of the rotating rod 64 is positioned between the fixed half-ring 61 and the movable ring 62. The bottom of the rotating rod 64 is inserted into the insertion hole of the horizontal frame 43. When the locking mechanism 6 fixes the position of the horizontal frame 43, the half ring of the rotating rod 64 is joined with the fixed half ring 61 in the vertical direction and then inserted. When the half ring of the rotating rod 64 is inserted between the fixed half ring 61 and the moving ring 62, the rotating rod 64 is rotated. Then the rotating rod 64 is released. Under the elastic force of the third spring 63, the fixed half ring 61 and the moving ring 62 clamp the half ring of the rotating rod 64. At the same time, the rotating rod 64 is inserted into the insertion hole of the horizontal frame 43.

[0053] A limiting bracket 10 is fixedly installed at the end of the sealing cover 8 away from the rotating shaft, and a turntable screw 11 is slidably installed on the limiting bracket 10, and the turntable screw 11 is threadedly connected to the threaded seat of the tank body 1. Since the ring in the middle of the turntable screw 11 is restricted inside the limiting bracket 10, the turntable screw 11 can move linearly along the axial direction.

[0054] Working principle:

[0055] Before sterilization, the sterilization device for processing wet pet food adjusts the distance between the two movable frames 53 of the same rotating clamping mechanism 5 by rotating the forward and reverse threaded rod 552 with a wrench according to the diameter of the can 7. Then, several cans 7 are placed on each rotating placement frame 51, and the movable clamping assembly 55 is adjusted to a suitable position to clamp the cans 7. That is, the movable clamping assembly 55 is moved to a suitable position, and then the hand screw 555 is tightened so that the hand screw 555 presses against the movable seat 551, thereby fixing the position of the movable seat 551.

[0056] Then, the horizontal frame 43 of the rotating cylinder 45 is inserted into the track 41. Next, the position of the horizontal frame 43 is locked by the rotating frame mechanism 4. That is, the half ring of the rotating rod 64 and the fixed half ring 61 are joined together in the vertical direction and then inserted. When the half ring of the rotating rod 64 is inserted between the fixed half ring 61 and the moving ring 62, the rotating rod 64 is rotated. Then the rotating rod 64 is released. Under the elastic force of the third spring 63, the fixed half ring 61 and the moving ring 62 clamp the half ring of the rotating rod 64. At the same time, the rotating rod 64 is inserted into the insertion hole of the horizontal frame 43.

[0057] Next, the sealing cap 8 is closed, and the drive motor 31 drives the first gear 34 to rotate. The first gear 34 drives the connecting seat 37 to rotate through the second gear 36. The rotating connecting seat 37 drives the rotating cylinder 45 to rotate at a low speed through the plug-in seat 38, causing several sets of rotating clamping mechanisms 5 to rotate. Then, the central nozzle 2 sprays steam from the nozzle to sterilize the cans 7 held on the rotating clamping mechanisms 5 at high temperature. During sterilization, the cans 7 remain vertical and rotate in a circular motion, allowing the central nozzle 2 to perform multi-angle, circumferential high-temperature sterilization of the cans 7, reducing sterilization dead zones for individual cans 7.

[0058] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
