Description

Technical Field

[0001] This utility model relates to the field of food packaging testing technology, specifically a food packaging sealing test device. Background Technology

[0002] In the food industry, the airtightness of food packaging is crucial. Good airtightness can prevent food from being contaminated by external air, moisture, microorganisms, and other pollutants, extend the shelf life of food, and ensure the quality and safety of food.

[0003] In the prior art, such as in CN220092193U, a sealing performance testing device for food packaging is disclosed. It includes a conveyor frame and a sliding plate. The sliding plate is fixedly connected to one side of the conveyor frame. A fixed plate is installed on the side of the conveyor frame away from the sliding plate. An L-shaped plate is fixedly connected to the upper end of the fixed plate. A testing component is installed on the fixed plate. The testing component includes an airbag, an air supply pipe, a sealed cavity, and a push rod. The airbag is fixedly connected to the fixed plate, and the sealed cavity is fixedly connected to the L-shaped plate. The air supply pipe is fixedly connected between the sealed cavity and the airbag. The push rod is slidably connected to one side wall of the sealed cavity. When the pressure plate no longer compresses the food packaging, the actuating plate rotates under the force of a torsion spring and pushes the food packaging onto the sliding plate. The sliding plate then collects the substandard food packaging.

[0004] Based on the above-mentioned existing technology, the existing food packaging sealing test devices still have the following problems. When the belt conveyor is continuously conveying food packaging to test its sealing, it is necessary to temporarily stop the operation of the belt conveyor. This not only makes the continuity of production poor and leads to low production efficiency, but also causes additional wear and tear on the mechanical parts of the belt conveyor due to frequent start-stop operations. Therefore, this utility model provides a food packaging sealing test device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a food packaging sealing performance testing device. This device solves the problem that when a belt conveyor is continuously conveying food packaging for sealing performance testing, it is necessary to briefly stop the belt conveyor. This not only results in poor production continuity and low production efficiency, but also causes additional wear and tear on the mechanical components of the belt conveyor due to frequent start-stop operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a food packaging sealing performance testing device, comprising a frame, with multiple columns mounted on the bottom surface of the frame and a belt conveyor mounted on the top of the frame. A sealing performance testing mechanism is provided on the frame near the end of the belt conveyor. The sealing performance testing mechanism includes: a height adjustment component mounted on the frame; and a reciprocating lifting component mounted on the height adjustment component. The reciprocating lifting component includes a fixed base, with a fixed frame mounted on the top surface of the fixed base. A straight groove and an inclined groove are provided through the side of the fixed frame, forming a guide channel structure between the straight groove and the inclined groove. The reciprocating lifting component also includes a sliding rod that can slide between the straight groove and the inclined groove. Sleeves are fixedly mounted at both ends of the sliding rod, and a mounting plate is fixedly connected between the bottom surfaces of the two sleeves. A pressure sensor is mounted on the bottom surface of the mounting plate, and the pressure sensor is positioned above the belt conveyor.

[0007] Preferably, the top surface of the fixed base is symmetrically mounted with upright plates, and a support plate is installed between the opposite side surfaces of the two upright plates. The support plate is positioned above the fixed frame, and the top surface of the support plate is symmetrically mounted with slide rails.

[0008] Preferably, a motor is mounted on the outer surface of one of the upright plates, the output shaft of the motor movably passes through the outer surface of the upright plate and extends to the other side, a reciprocating lead screw is mounted on the output shaft of the motor, and one end of the reciprocating lead screw is rotatably mounted on another upright plate.

[0009] Preferably, the reciprocating screw has a sliding plate threaded onto its outer wall, and the bottom of the sliding plate is slidably connected to the slide rail.

[0010] Preferably, guide posts are symmetrically installed on the bottom surface of the skateboard near the edge, and the guide posts are slidably connected to the sleeve rod.

[0012] Beneficial effects

[0013] This invention provides a device for detecting the airtightness of food packaging. Compared with the prior art, it has the following advantages:

[0014] (1) The food packaging sealing test device slides in the guide channel formed by the straight groove and the inclined groove of the fixed frame through the sliding rod, so that the pressure sensor can continuously follow the food packaging on the belt conveyor to move synchronously, so that the two are relatively stationary. At the same time, the height of the pressure sensor also changes, so that the pressure sensor contacts the food packaging and applies pressure, and monitors the pressure data in real time to determine the sealing of the food packaging. It can realize the sealing test of food packaging under the continuous operation of the belt conveyor, avoiding the frequent start and stop of the belt conveyor due to the test, which not only ensures the continuity of production and improves production efficiency, but also reduces the additional wear on the mechanical parts of the belt conveyor.

[0015] (2) The food packaging sealing test device can drive the lifting plate to move up and down through the electric push rod, thereby causing the height of the fixed base and the entire reciprocating lifting assembly above it to change. It can be flexibly adjusted according to the height requirements of different food packaging, ensuring that the pressure sensor can accurately contact the food packaging and apply appropriate pressure, so as to achieve effective detection of the sealing of food packaging of different specifications, improve the versatility and adaptability of the device, and meet the diverse food packaging testing needs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides two technical solutions:

[0023] Figures 1-4 The first embodiment is shown: a food packaging sealing test device, including a frame 1, a plurality of columns 11 mounted on the bottom surface of the frame 1, a belt conveyor 2 mounted on the top of the frame 1, and a sealing test mechanism located on the frame 1 near the end of the belt conveyor 2. The sealing test mechanism includes: a height adjustment component 3 mounted on the frame 1; and a reciprocating lifting component 4 mounted on the height adjustment component 3. The reciprocating lifting component 4 includes a fixed base 41, and a fixed frame 48 mounted on the top surface of the fixed base 41 for fixing... The frame 48 has a straight slot 481 and an inclined slot 482 through it. The straight slot 481 and the inclined slot 482 form a guide channel structure. The reciprocating lifting assembly 4 also includes a slide rod 411 that can slide between the straight slot 481 and the inclined slot 482. Both ends of the slide rod 411 are fixedly installed with sleeve rods 410. The bottom surfaces of the two sleeve rods 410 are fixedly connected to a mounting plate 412. A pressure sensor 413 is installed on the bottom surface of the mounting plate 412. The pressure sensor 413 is placed above the belt conveyor 2.

[0024] Specifically, the slide rod 411 slides within the guide channel formed by the straight groove 481 and the inclined groove 482 of the fixed frame 48. When the slide rod 411 slides downward inside the inclined groove 482, the sleeve rod 410 drives the mounting plate 412 and the pressure sensor 413 to gradually descend, contacting and applying pressure to the food packaging passing on the belt conveyor 2. When the slide rod 411 slides inside the straight groove 481, the pressure sensor 413 can continuously move synchronously with the packaging, keeping them relatively stationary. The pressure sensor 413 monitors the pressure data in real time to determine the sealing performance of the food packaging. This enables the sealing performance detection of the food packaging while the belt conveyor 2 is running continuously, avoiding frequent start-stop of the belt conveyor 2 for detection. This ensures the continuity of production, improves production efficiency, and reduces additional wear on the mechanical parts of the belt conveyor 2.

[0025] In this embodiment, a vertical plate 42 is symmetrically mounted on the top surface of the fixed base 41, and a support plate 43 is mounted between the opposite side surfaces of the two vertical plates 42. The support plate 43 is positioned above the fixed frame 48. A slide rail 44 is symmetrically mounted on the top surface of the support plate 43. A motor 45 is mounted on the outer surface of one of the vertical plates 42. The output shaft of the motor 45 moves through the outer surface of the vertical plate 42 and extends to the other side. A reciprocating screw 46 is mounted on the output shaft of the motor 45. One end of the reciprocating screw 46 is rotatably mounted on the other vertical plate 42. A sliding plate 47 is threaded onto the outer wall of the reciprocating screw 46. The bottom of the sliding plate 47 is slidably connected to the slide rail 44. Guide posts 49 are symmetrically mounted on the bottom surface of the sliding plate 47 near the edge. The guide posts 49 are slidably connected to the sleeve rod 410.

[0026] Specifically, the motor 45 starts and drives the reciprocating screw 46 to rotate. When the reciprocating screw 46 rotates, the slide plate 47 will reciprocate linearly along the axis of the screw under the push of the screw thread. The slide rail 44 can provide guidance for the slide plate 47. When the slide plate 47 moves in the horizontal direction, the guide post 49 moves accordingly. Through the sliding engagement with the sleeve rod 410, the horizontal movement of the slide plate 47 can be transmitted to the sleeve rod 410, thereby driving the slide rod 411 to slide in the slot of the fixed frame 48. At the same time, when the height of the slide rod 411 changes, such as when it slides in the inclined slot 482 and causes it to rise or fall, the sliding connection between the guide post 49 and the sleeve rod 410 can adapt to this height change, ensuring the effectiveness of the connection and enabling the entire transmission structure to work stably under different motion states.

[0027] Figures 1-4 The second embodiment is shown. The main difference from the first embodiment is that the height adjustment component 3 includes an electric push rod 31 installed on the bottom surface of the frame 1. A lifting plate 32 is installed at the telescopic end of the electric push rod 31. A support frame 33 is installed on the top surface of the lifting plate 32, which slides through the bottom surface of the frame 1 and extends upward. The top surface of the support frame 33 is fixedly connected to the bottom surface of the fixed seat 41.

[0028] Specifically, the electric actuator 31 can drive the lifting plate 32 to move up and down, thereby causing the height of the fixed base 41 and the entire reciprocating lifting assembly 4 above it to change. It can be flexibly adjusted according to the height requirements of different food packaging, ensuring that the pressure sensor 413 can accurately contact the food packaging and apply appropriate pressure, so as to achieve effective detection of the sealing performance of food packaging of different specifications, improve the versatility and adaptability of the device, and meet the diverse food packaging detection needs.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] When the device is running, multiple food packages are arranged at equal intervals on the belt conveyor 2 and continuously conveyed. The electric actuator 31 in the height adjustment assembly 3 extends and retracts to move the lifting plate 32 up and down according to the height requirements of different food packages. This causes the support frame 33 to adjust the fixed base 41 and its components to the appropriate height, ensuring that the pressure sensor 413 can accurately act on the food package. Then, the motor 45 starts, driving the reciprocating screw 46 to rotate, causing the slide plate 47 to reciprocate linearly under the guidance of the slide rail 44. The moving speed of the slide plate 47 is the same as the conveying speed of the food package. The slide plate 47 is connected to the slide rod 411 through the guide post 49 and the sleeve rod 410, thereby causing the slide rod 411 to slide within the guide channel formed by the straight groove 481 and the inclined groove 482 of the fixed frame 48. When the slide rod 411 is in the inclined groove... As the sleeve rod 410 slides downward inside the slot 482, it drives the mounting plate 412 and pressure sensor 413 to gradually descend, contacting and applying pressure to the food packaging passing on the belt conveyor 2. When the slide rod 411 slides inside the straight slot 481, the pressure sensor 413 can continuously move synchronously with the packaging, keeping them relatively stationary. The pressure sensor 413 monitors the pressure data in real time to determine the sealing performance of the food packaging. This enables the sealing performance detection of the food packaging while the belt conveyor 2 is running continuously, avoiding frequent start-stop of the belt conveyor 2 for detection. This ensures the continuity of production, improves production efficiency, and reduces additional wear on the mechanical parts of the belt conveyor 2.
