Description

Technical Field

[0001] This utility model belongs to the field of food sterilization technology, specifically relating to a sterilization mechanism for food production and processing. Background Technology

[0002] High-intensity ultraviolet (UV) light can be used to irradiate the surface of food during food production and processing to sterilize it. In current UV sterilization equipment, food is placed on a conveyor belt and transported to the UV sterilization range. However, during batch sterilization, the UV lamps located below the food are blocked by the support structure of the conveyor belt when they irradiate the food. The parts of the food that come into contact with the support structure cannot be irradiated by the UV light, resulting in ineffective sterilization of these parts. Utility Model Content

[0003] This invention provides a sterilization mechanism for food production and processing, which can change the position of the shielding on the food, so that the high-intensity ultraviolet lamp can effectively carry out comprehensive sterilization of the food.

[0004] This utility model provides the following technical solution: a sterilization mechanism for food production and processing, including a food sterilization chamber, a high-intensity ultraviolet lamp, and a support frame. Two conveyor belts are installed inside the support frame. Each of the two conveyor belts has several evenly distributed clearance adjustment holes on its sidewall. A food support rod is slidably connected to the inner wall of each clearance adjustment hole. A support plate is provided on the opposite side of each of the two conveyor belts. A friction pad is provided on one side of each support plate. A rotating support disc is provided on the opposite side of each of the two conveyor belts. An air bladder is provided on one side of each rotating support disc.

[0005] The food support rod has a lubricating pad layer fixedly connected to its outer wall, and a limiting friction block is fixedly connected to its outer wall, which engages with both sides of the conveyor belt.

[0006] The support plate has a support connecting rod fixedly connected to its side wall, and the support connecting rod is fixedly connected to the support frame.

[0007] The friction pad is rotatably connected to one side with an adjusting rod, which extends outward through the support plate and the support frame.

[0008] The inner wall of the spacer airbag is fixedly connected with a friction pad, which is in contact with the limiting friction block.

[0009] A drive rod is fixedly connected to the side wall of the rotating support disk, and the drive rod extends outward through the support frame.

[0010] The spacer airbag has an air supply pipe fixedly connected to its side wall.

[0011] The beneficial effects of this utility model are as follows: by allowing the food support rod to be positioned with the adjustment hole, and by driving the food support rod with the conveyor belt, combined with the friction of the support plate and friction pad, the food support rod can move backward sequentially when passing the positions of the support plate and friction pad. In addition, the counterclockwise drive of the rotating support plate and the spacer airbag on the food support rod allows the food to be relatively displaced with the food support rod during the conveying process, thereby changing the position of the food support rod blocking the food, so that the high-intensity ultraviolet lamp can effectively carry out comprehensive sterilization of the food.

[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] Please see Figures 1-4 The present invention provides the following technical solution: a sterilization mechanism for food production and processing, comprising a food sterilization chamber 1, a high-intensity ultraviolet lamp 11 and a support frame 12, wherein two conveyor belts 2 are installed inside the support frame 12, and several evenly distributed clearance adjustment holes 21 are opened on the side walls of the two conveyor belts 2, and food support rods 22 are slidably connected to the inner walls of the clearance adjustment holes 21. Support plates 3 are provided on the opposite sides of the two conveyor belts 2, and friction pads 31 are provided on one side of the support plates 3. Rotating support discs 4 are provided on the opposite sides of the two conveyor belts 2, and spacer airbags 41 are provided on one side of the rotating support discs 4.

[0019] In this implementation plan: Before sterilizing the food, the staff starts the drive device of the conveyor belt 2 via the controller. After the conveyor belt 2 rotates one revolution, the food support rods 22 are all in an orderly position. Then, the staff places the food on the top of the food support rods 22 in sequence. The conveyor belt 2 drives the food support rods 22 to move, further driving the food movement. When the food passes the corresponding position of the food sterilization chamber 1 and the high-intensity ultraviolet lamp 11, the high-intensity ultraviolet lamp 11 sterilizes the food with ultraviolet light. Through the clearance adjustment hole 21 to allow the food support rods 22 to move, and the conveyor belt 2 to drive the food support rods 22, when passing the position of the support plate 3 and the friction pad 31, the limiting friction block 24 moves relative to the conveyor belt 2 under the friction resistance applied by the friction pad 31. The multiple food support rods 22 move backward in sequence. When the food support rod 22 passes the corresponding position of the rotating support plate 4 and the spacer air bag 41, the rotating support plate 4, the spacer air bag 41 and the friction pad 42 drive the food support rod 22 to move by friction, realizing the counterclockwise drive of the food support rod 22. This allows the food to be displaced relative to the food support rod 22 during the conveying process, changing the position of the food support rod 22 blocking the food. This allows the part of the front end that is not directly irradiated by ultraviolet light to be directly irradiated by ultraviolet light, so that the high-intensity ultraviolet lamp 11 can effectively carry out comprehensive sterilization of the food. In actual use, the rotation speed of the rotating support plate 4 is greater than the rotation speed of the conveyor belt 2. The movement speed of the conveyor belt 2 and the intensity of the high-intensity ultraviolet lamp 11 are set according to different food sterilization requirements. The distribution density and spacing of the food support rod 22 are adjusted according to actual needs.

[0020] A lubricating pad 23 is fixedly connected to the outer wall of the food support rod 22, and a limiting friction block 24 is fixedly connected to the outer wall of the food support rod 22. The limiting friction block 24 is engaged on both sides of the conveyor belt 2. By setting the lubricating pad 23, the coefficient of friction of the surface of the food support rod 22 can be reduced, thereby reducing the friction between the food support rod 22 and the food and preventing the food support rod 22 from moving synchronously with the conveyor belt 2 when it is relatively displaced. This allows the food support rod 22 to move relative to the food. The limiting friction block 24 can limit the food support rod 22 so that it will not lose contact with the conveyor belt 2. At the same time, the limiting friction block 24 is in close contact with the contact surface of the conveyor belt 2. The food support rod 22 is positioned by the friction between the limiting friction block 24 and the conveyor belt 2, preventing the food support rod 22 from sliding freely during movement and causing the position of the food support rod 22 to obstruct the food uncontrollably.

[0021] A support connecting rod 32 is fixedly connected to the side wall of the support plate 3, and the support connecting rod 32 is fixedly connected to the support frame 12; by setting the support connecting rod 32, the support plate 3 can be supported, so that the support plate 3 can move relative to the conveyor belt 2.

[0022] An adjusting rod 33 is rotatably connected to one side of the friction pad 31. The adjusting rod 33 extends outward through the support plate 3 and the support frame 12. The position of the friction pad 31 can be adjusted by setting the adjusting rod 33, so as to adjust the force applied by the friction pad 31 to the limiting friction block 24. The adjusting rod 33 is threadedly connected to the support frame 12. The position of the friction pad 31 can be adjusted by rotating the adjusting rod 33.

[0023] A friction pad 42 is fixedly connected to the inner wall of the spacer airbag 41, and the friction pad 42 contacts the limiting friction block 24; by setting the friction pad 42, the friction between the spacer airbag 41 and the limiting friction block 24 can be increased.

[0024] A drive rod 43 is fixedly connected to the side wall of the rotating support disk 4. The drive rod 43 extends outward through the support frame 12. By setting the drive rod 43, the rotating support disk 4 can be driven to rotate, thereby driving the spacer airbag 41 and the friction pad 42 to rotate, thereby driving the limiting friction block 24 to move. The rotating support disk 4 is in a high-speed rotating state. With the help of the spacer airbag 41, it can play a buffering role. When subjected to strong resistance, it can deform to make way, avoiding excessive force on the limiting friction block 24.

[0025] A gas supply pipe 44 is fixedly connected to the side wall of the spacer airbag 41; by setting the gas supply pipe 44, gas can be delivered to the spacer airbag 41 and gas can be discharged from the spacer airbag 41. Under normal conditions, the end of the gas supply pipe 44 is in a closed state.

[0026] The working principle and usage process of this utility model are as follows: Before sterilizing the food, the operator starts the drive device of the conveyor belt 2 through the controller. After the conveyor belt 2 rotates one revolution, the operator places the food on the top of the food support rod 22 in sequence. The conveyor belt 2 drives the food support rod 22 to move, further driving the food movement. When the food passes the corresponding position of the food sterilization chamber 1 and the high-intensity ultraviolet lamp 11, the high-intensity ultraviolet lamp 11 sterilizes the food with ultraviolet light. When passing the position of the support plate 3 and the friction pad 31, the limiting friction block 24 is stopped by the friction pad 3. The applied frictional resistance causes relative movement with the conveyor belt 2, and multiple food support rods 22 move backward in sequence. When the food support rods 22 pass the corresponding positions of the rotating support plate 4 and the spacer air bag 41, the rotating support plate 4, the spacer air bag 41 and the friction pad 42 drive the food support rods 22 to move by friction, thereby achieving counterclockwise drive of the food support rods 22. This allows the food to be displaced relative to the food support rods 22 during the conveying process, thereby changing the blocking position of the food support rods 22 on the food, so that the front part that is not directly exposed to ultraviolet rays is directly exposed to ultraviolet rays.
