Description

Technical Field

[0001] This utility model relates to the technical field of food conveying, specifically to a conveying structure for a food quick-freezing machine. Background Technology

[0002] A quick-freezing machine freezes items to a core temperature of -18°C within a short time, allowing them to pass quickly through an ice crystal production belt within 30 minutes. This process aims to reduce nutrient loss and preserve the original flavor. It can effectively and economically freeze a variety of products placed inside the quick-freezing machine, such as meat, fish, shrimp, meatballs, vegetables, prepared foods, and dairy products of various shapes.

[0003] In existing food quick-freezing machines, the conveyor structure is usually equipped with a conveyor belt for transporting food. However, during the quick-freezing process, food may stick to the conveyor belt, which is not conducive to the feeding of food and affects the smoothness of the conveying. In addition, during the conveying process, moisture may cause ice crystals to accumulate on the conveyor belt. If these are not cleaned, they will further affect the freezing and conveying of food, resulting in poor performance.

[0038] Example 2

[0039] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-9 The anti-adhesion component 9 includes push plates 91 respectively disposed on the front and rear sides of the freezer compartment 8 near the bottom, with the push plates 91 arranged alternately from left to right. Several push rods 92 are fixedly installed at equal intervals on opposite sides of the push plates 91, with the opposite ends of the push rods 92 slidingly extending into the inner cavity of the freezer compartment 8. A movable plate 93 is disposed below the bottom of each push plate 91, and a movable rack plate 94 is fixedly installed in the middle of the opposite side of each movable plate 93. Two movable gears 95 are disposed on the opposite side of each movable rack plate 94 near the inner side, and the movable gears 95 are arranged vertically, with the lower movable gear... The movable gear 95 and the adjacent movable rack plate 94 are meshed. The middle part of the upper part of the adjacent movable gear 95 is fixedly installed with a rotating shaft. The lower end of the rotating shaft is movably installed on the base 1. The movable rack plate 96 is meshed on the opposite side of the upper movable gear 95. The movable rack plate 96 is arranged front and back. The fixed plate 97 is fixedly installed on the opposite side of the movable rack plate 96. The threaded plate 98 is provided on the lower part of the opposite side of the fixed plate 97. The threaded rod 99 is threaded through the threaded plate 98 near the opposite side. The external threads of the threaded rod 99 on the front and back sides are arranged oppositely.

[0040] A connecting rod 971 is fixedly installed on the opposite side of the fixed plate 97 near the bottom. The end of the connecting rod 971 away from the adjacent fixed plate 97 is fixedly installed on the adjacent threaded plate 98, which can drive the fixed plate 97 to move left and right synchronously with the threaded plate 98.

[0041] Both ends of the threaded rod 99 are provided with side plates 991, and the bottom of the side plates 991 are fixedly installed on the base 1. The left end of the threaded rod 99 is movably installed on the left side plate 991, and the right end of the threaded rod 99 extends movably through to the outside of the right side plate 991. A rotating gear 992 is fixedly sleeved on the outside of the threaded rod 99 near the right end. The top of the front rotating gear 992 meshes with a translation rack plate 993, which provides rotational support for the threaded rod 99 and facilitates its rotational operation.

[0042] Vertical rods 931 are fixedly installed on the top of the movable plate 93 near the left and right sides, and the upper ends of the vertical rods 931 are fixedly installed on the adjacent push plates 91 respectively. L-shaped sliding rods 932 are fixedly installed in the middle of the bottom of the vertical rods 931. Two sliding openings are opened on the base 1 near the middle, and the sliding openings are arranged left and right. The opposite ends of the L-shaped sliding rods 932 slide into the inner cavity of the adjacent sliding openings respectively, which can drive the push plate 91 to move back and forth synchronously with the adjacent movable plate 93. At the same time, it also serves to guide and limit the movement of the movable plate 93, resulting in good stability.

[0043] In this embodiment: when the threaded sleeve 74 moves back and forth, it drives the translation rack plate 993 to move back and forth via the crossbar. When the translation rack plate 993 moves backward, it drives the front rotating gear 992 to rotate. When the rotating gear 992 rotates, it drives the front threaded rod 99 to rotate. When the front threaded rod 99 rotates, it drives the adjacent threaded plate 98 to move to the right. When the front threaded plate 98 moves to the right, it drives the fixed plate 97 to move to the right via the connecting rod 971. When the fixed plate 97 moves to the right, it drives the adjacent movable gear 95 to rotate via the movable rack plate 96. When the upper movable gear 95 rotates, it drives the lower movable gear 95 to rotate. When the lower movable gear 95 rotates, it drives the front threaded plate 98 to rotate. When the moving rack plate 94 moves backward, the front moving rack plate 94 moves backward, which in turn drives the push plate 91 to move backward through the moving plate 93 and the vertical rod 931. When the push plate 91 moves backward, it drives the adjacent push rod 92 to move backward, thus pushing the food and preventing it from sticking to the conveyor belt 6. As the translation rack plate 993 continues to move backward, it drives the rear rotating gear 992 to rotate, which in turn drives the rear movable rack plate 96 to move to the left, which facilitates the movement of the rear push rod 92 forward, pushing the food forward. When the translation rack plate 993 moves backward, it drives the front and rear push rods 92 to return to their original positions, thus continuously pushing the food back and forth.

[0044] Working principle: During use, the food to be frozen can be placed on the conveyor belt 6. After placement, the drive motor 5 can be started. The drive motor 5 drives the left-side rotating shaft to rotate, which in turn drives the left-side conveyor roller 4 to rotate. This, in turn, drives the conveyor belt 6 to rotate, thus conveying and discharging the food. When the food is conveyed into the freezing chamber 8, it will be quickly frozen. In addition, the servo motor 73 and the heater 75 can also be started. The servo motor 73 drives the screw 72 to rotate, which in turn drives the threaded sleeve 74 to move back and forth. The back and forth movement of the threaded sleeve 74 drives the heater 75 to move back and forth through the L-shaped rod 751. When the heater 75 is running, it blows hot air onto the conveyor belt 6. This process melts the ice on conveyor belt 6. As heater 75 moves back and forth, it also drives brush 77 to move back and forth at the bottom of conveyor belt 6 via rotating rod 76. The movement of heater 75 also drives transmission gear 763 to move on transmission rack plate 764 via L-shaped plate and movable rod. At this time, transmission gear 763 rotates under the action of transmission rack plate 764. The rotation of transmission gear 763 drives movable rod to rotate, which in turn drives driving bevel gear 762. The rotation of driving bevel gear 762 drives rotating rod 76 via driven bevel gear 761. The rotation of rotating rod 76 then drives brush 77 to rotate, thus removing ice from conveyor belt 6 and making it... It falls into the inner cavity of the collection trough 766, serving as a collection point. Additionally, when the threaded sleeve 74 moves back and forth, it also drives the translation rack plate 993 to move back and forth via the crossbar. When the translation rack plate 993 moves backward, it drives the front rotating gear 992 to rotate. The rotation of the rotating gear 992 drives the front threaded rod 99 to rotate. The rotation of the front threaded rod 99 drives the adjacent threaded plate 98 to move to the right. The movement of the front threaded plate 98 to the right drives the fixed plate 97 to move to the right via the connecting rod 971. The movement of the fixed plate 97 to the right drives the adjacent movable gear 95 to rotate via the movable rack plate 96. The rotation of the upper movable gear 95 drives the lower movable gear 95 to rotate. When rotating, the front movable rack plate 94 moves backward. When the front movable rack plate 94 moves backward, it drives the push plate 91 to move backward through the movable plate 93 and the vertical rod 931. When the push plate 91 moves backward, it drives the adjacent push rod 92 to move backward, which pushes the food and prevents it from sticking to the conveyor belt 6. As the translation rack plate 993 continues to move backward, it drives the rear rotating gear 992 to rotate, which drives the rear movable rack plate 96 to move to the left, which facilitates the movement of the rear push rod 92 forward and pushes the food forward. When the translation rack plate 993 moves backward, it drives the front and rear push rods 92 to return to their original positions, which continuously pushes the food back and forth.
