Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a rapid food quality testing device.

[0024] This utility model provides, for example Figure 1-3 The food quality rapid testing device shown includes a mounting frame 1. Two symmetrically arranged bases 21 are fixedly provided at the bottom of the mounting frame 1. Rotating rods 2 are rotatably provided at both ends inside the mounting frame 1. Transmission rollers 3 are fixedly sleeved on the rod walls of the rotating rods 2. Transmission belts 4 are provided on the roller walls of the two transmission rollers 3. A motor 5 is fixedly provided on the outside of the mounting frame 1. The output shaft of the motor 5 is fixedly connected to the rotating rods 2.

[0025] A mounting bracket 6 is fixedly installed on the back side of the mounting bracket 1. A push rod 7 is slidably installed on the top of the mounting bracket 6. A sealing cover 8 is slidably fitted on the lower end of the push rod 7. The sealing cover 8 is a transparent sealing cover. A pressure plate 9 is fixedly installed on the bottom of the push rod 7. A spring 10 is fitted on the rod wall of the push rod 7. The two ends of the spring 10 are fixedly connected to the push rod 7 and the sealing cover 8 respectively. A gas sensor 11 is fixedly embedded on the side of the sealing cover 8.

[0026] In order to ensure stable conveying of puffed food packaging via the transmission belt 4 while simultaneously driving the sealing cover 8 and pressure plate 9 to move stably downwards for leak detection, such as... Figure 1-3 As shown, a movable frame 12 is provided on the back side of the fixed frame 6. A push plate 13 is fixedly provided on the lower end of the outer wall of the movable frame 12. The movable frame 12 is fixedly sleeved on the upper end of the push rod 7. A guide groove 18 is provided on the side of the fixed frame 6. A guide block 19 is fixedly provided on the lower end of the inner wall of the movable frame 12. The guide block 19 is slidably disposed in the guide groove 18. A limiting plate 20 is fixedly sleeved on the outer wall of the guide block 19. The limiting plate 20 is in contact with the inner wall of the fixed frame 6. A drive rod 14 is rotatably provided on the back side of the fixed frame 6. A push block 15 is fixedly sleeved on the rod wall of the drive rod 14. The push block 15 is in contact with the push plate 13. Synchronous pulleys 16 are fixedly sleeved on the ends of the rotating rod 2 and the drive rod 14. A synchronous belt 17 is provided on the outer side of the two synchronous pulleys 16.

[0027] Testing method: First, connect the device to the power supply and start the motor 5. The output shaft of the motor 5 drives the rotating rod 2, which is fixedly connected to it, to rotate. The transmission roller 3, which is fixedly sleeved on the rotating rod 2, rotates accordingly, which in turn drives the transmission belt 4 to run. Place the puffed food to be tested on the transmission belt 4 in sequence. The transmission belt 4 runs continuously, stably conveying the food towards the sealing cover 8.

[0028] While the conveyor belt 4 is conveying food, the synchronous pulley 16 at the end of the rotating rod 2 will rotate together with the rotating rod 2. Since the two synchronous pulleys 16 are connected by the synchronous belt 17, the synchronous pulley 16 at the end of the drive rod 14 will also rotate, thereby driving the drive rod 14 to rotate. The push block 15, which is fixedly sleeved on the wall of the drive rod 14, rotates with the drive rod 14. When the push block 15 rotates to contact the push plate 13 at the lower end of the outer wall of the movable frame 12, the push block 15 will push the push plate 13, causing the movable frame 12 to move downward along the fixed frame 6.

[0029] The movable frame 12 is fixedly sleeved on the upper outer part of the push rod 7, so the push rod 7 will move downward together with the movable frame 12. The pressure plate 9 fixed at the bottom of the push rod 7 and the sealing cover 8 slidably sleeved at the lower end will also move downward synchronously. During the downward movement of the sealing cover 8, the guide block 19 slides in the guide groove 18. The limiting plate 20 fixedly sleeved on the outer wall of the guide block 19 contacts and cooperates with the inner wall of the fixed frame 6. This not only ensures that the sealing cover 8 and the push rod 7 move stably in the longitudinal direction, but also prevents the movable frame 12 from shifting during the movement.

[0030] When the sealing cover 8 moves down to completely cover the puffed food packaging bag, the push rod 7 continues to move downward. At this time, the spring 10 is compressed. Since the two ends of the spring 10 are fixedly connected to the push rod 7 and the sealing cover 8 respectively, under the elastic force of the spring 10, the pressure plate 9 will apply a certain pressure to the packaging bag and squeeze the packaging bag. If there is an air leak in the packaging bag, the gas inside will leak into the sealing cover 8. The gas sensor 11 fixedly embedded on the side of the sealing cover 8 will detect the change in gas concentration. After completing one detection, the drive rod 14 continues to rotate, the push block 15 disengages from the push plate 13, and under the elastic force of the spring 10, the push rod 7, the sealing cover 8 and the pressure plate 9 return to their original positions. The transmission belt 4 continues to transport the next bag of puffed food for detection.

[0031] If a leaking packaging bag is found, the corresponding food product should be removed and disposed of promptly to ensure that the packaging of puffed food entering the market is intact and to guarantee food quality and safety.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
