Description

Technical Field

[0001] This utility model relates to the field of food packaging equipment technology, and more specifically, to a food packaging bag damage detection device. Background Technology

[0002] Food packaging bags are a type of packaging design. In order to facilitate the preservation and storage of food, product packaging bags have been developed. Food packaging bags refer to thin film containers that come into direct contact with food and are used to hold and protect food. After the production of food packaging bags, damage detection devices are needed to detect whether the packaging bags are damaged.

[0003] Existing food packaging bag damage detection devices typically detect damage by pressing the packaging bags directly from the outside. However, external light, wind, or other objects can interfere with the detection equipment's ability to accurately identify and detect the bags. Furthermore, the lack of a limiting and pushing structure during the sorting of damaged bags makes it easy for them to shift or fall, compromising sorting efficiency and accuracy. Additionally, the equipment's components are difficult to maintain and replace, and the structure for collecting damaged items lacks flexibility, failing to meet the demands of automated production for efficient, accurate, and convenient packaging bag damage detection.

[0004] This invention can effectively ensure the accuracy of food packaging bag damage detection and the continuity of the production process. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a food packaging bag damage detection device, comprising: a transport platform;

[0007] The inspection team is located above the transport platform;

[0008] A guide plate is fixedly installed on one side of the transport platform;

[0009] A collection box is located below the guide plate;

[0010] A limiting frame is fixedly installed on the other side of the transport platform;

[0011] A pusher assembly is located on one side of the limiting frame;

[0012] The detection group includes a sealing cover, a pressing plate, an electric telescopic rod, and a gas sensor. The pressing plate is located inside the sealing cover. One end of the electric telescopic rod is fixedly installed inside the upper part of the sealing cover, and the other end is fixedly installed on the upper part of the pressing plate. The gas sensor is fixedly installed on the inner wall of the sealing cover. A sealing strip is provided at the bottom of the sealing cover. A hydraulic rod is fixedly installed at the upper part of the sealing cover, and the upper end of the hydraulic rod is fixedly installed inside the limit frame.

[0013] The push assembly includes a second hydraulic rod and a push plate. The second hydraulic rod is embedded inside the limiting frame, and the output end of the second hydraulic rod is fixedly installed on one side of the push plate.

[0014] A further preferred embodiment: a rotating rod is provided through both ends of the push plate, the rotating rod is movably connected to the push plate, and a motor is fixedly installed at one end of the rotating rod. Two railings are nested on the outer surface of the rotating rod, and the two railings are respectively located on both sides of the push plate.

[0015] A further preferred embodiment: a positioning plate is fixedly installed on both sides of the push plate, the positioning plate is located below the two railings, and the bottom of the two railings contacts the upper end of the positioning plate after rotation.

[0016] A further preferred embodiment: the two railings are located on both sides of the guide plate, the bottom of the guide plate is inclined, the top of the collection box contacts the bottom of the guide plate, and the bottom of the collection box is equipped with casters.

[0017] A further preferred embodiment: a connecting block is fixedly installed on the upper end of the sealing strip, the interior of the sealing strip is hollow, and a protrusion is provided on the inner side of the sealing strip, the protrusion being inclined.

[0018] A further preferred embodiment: the bottom of the sealing cover is provided with a slot, and both the connecting block and the protrusion can be embedded in the slot. The slot and the connecting block and the protrusion respectively fit into each other, and the sealing strip and the sealing cover are detachably connected.

[0019] A further preferred embodiment: a groove is provided on one side of the limiting frame, the second hydraulic rod is installed inside the groove, and one side of the push plate is in contact with one side of the limiting frame.

[0020] A further preferred embodiment: the bottom of the transport platform is fixedly equipped with several support legs, and a controller is provided on the outside, with the controller electrically connected to each electronic device.

[0021] Beneficial effects:

[0022] 1. By incorporating a sealing strip and adopting a detachable design, the connecting block and the protrusion can be embedded into the slot at the bottom of the sealing cover, and the three fit together perfectly. This not only facilitates the maintenance and replacement of the sealing strip by the staff, reducing the difficulty and cost of subsequent equipment maintenance, but also significantly enhances the sealing performance between the sealing cover and the conveyor table through the double fit of the connecting block, the protrusion, and the slot. At the same time, the sealing strip is hollow inside, and the inclined protrusion on the inner side can further fit against the top of the packaging bag when the sealing cover is pressed down, optimizing the sealing environment. This provides a reliable sealing guarantee for the gas sensor to accurately detect whether the packaging bag is damaged, effectively avoiding gas leakage interference caused by poor sealing, reducing the detection false judgment rate, thereby improving the accuracy and reliability of the entire damage detection process, ensuring that only truly damaged packaging bags are sorted out, and guaranteeing the rigor of product quality inspection.

[0023] 2. By incorporating a pusher assembly, the efficiency of sorting damaged packaging bags is improved. Rotating rods connected to movable railings at both ends of the pusher plate, driven by a motor, allow the railings to unfold and retract. When a damaged packaging bag is detected, the railings unfold to limit its movement on both sides, preventing the bag from shifting or falling during the pusher plate movement by the hydraulic rod, ensuring accurate sliding of the bag to the guide plate and improving sorting accuracy. After sorting, the railings retract, and the pusher plate smoothly resets without affecting the normal operation of the subsequent transport platform. Furthermore, the hydraulic rod is embedded in the groove of the limiting frame, allowing one side of the pusher plate to fit snugly against the limiting frame, optimizing the compactness of the equipment structure, reducing space occupation, and protecting the hydraulic rod, extending its service life. The positioning plates on both sides of the pusher plate provide stable support when the railing retracts, ensuring the stability of the railing's state switching. Overall, the pusher assembly, through the ingenious coordination of its mechanical structure, achieves automated and precise sorting of damaged packaging bags, reducing errors from manual intervention, improving production efficiency, and ensuring the stability and compactness of the equipment structure.

[0024] 3. In summary, this food packaging bag damage detection device, through the inclusion of a sealing strip and other structures, employs a detachable connecting block, a double-fitting structure of protrusions and grooves, and an inner inclined protrusion to optimize the seal. This not only improves the sealing performance and accuracy of the detection but also facilitates maintenance and replacement. The rotating rod, railing, and motor of the pushing group work together to achieve limited pushing of damaged packaging bags, and the concealed design of the hydraulic rod optimizes the structural compactness. The universal wheel design of the collection box facilitates movement and cleaning. The overall device boasts a high degree of automation, accurate detection, efficient sorting, stable structure, and convenient maintenance, effectively ensuring the accuracy of food packaging bag damage detection and the continuity of the production process.

[0031] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0032] Please see Figure 1-5 In this embodiment of the present invention, a food packaging bag damage detection device includes: a transport platform 1; a detection group 2 disposed above the transport platform 1; a guide plate 3 fixedly installed on one side of the transport platform 1; a collection box 4 disposed below the guide plate 3; a limiting frame 5 fixedly installed on the other side of the transport platform 1; and a pushing group 6 disposed on one side of the limiting frame 5. The detection group 2 includes a sealing cover 201, a pressing plate 202, an electric telescopic rod 203, and a gas sensor 204. The pressing plate 202 is disposed inside the sealing cover 201, and one end of the electric telescopic rod 203 is fixedly installed inside the upper part of the sealing cover 201. The other end is fixedly installed on the upper end of the pressing plate 202. The gas sensor 204 is fixedly installed on the inner wall of the sealing cover 201. A sealing strip 7 is provided at the bottom of the sealing cover 201. A hydraulic rod 205 is fixedly installed at the upper end of the sealing cover 201. The upper end of the hydraulic rod 205 is fixedly installed inside the limiting frame 5. The pushing group 6 includes a second hydraulic rod 601 and a push plate 602. The second hydraulic rod 601 is embedded inside the limiting frame 5, and the output end of the second hydraulic rod 601 is fixedly installed on one side of the push plate 602. Several support legs are fixedly installed at the bottom of the transport table 1, and a controller is provided on the outside. The controller is electrically connected to each electronic device.

[0033] The specific detection method in this embodiment can be found in patent publication number CN222618104U, which is prior art and will not be described in detail in this embodiment.

[0034] The food packaging bag is placed on the transport platform 1, which moves it towards the detection group 2. When the packaging bag moves below the sealing cover 201, the hydraulic rod 205 lowers the sealing cover 201, and the bottom sealing strip 7 creates a sealed space between the sealing cover 201 and the transport platform 1. Then, the electric telescopic rod 203 pushes the pressing plate 202 to press the packaging bag down. If the packaging bag is damaged, the internal gas will leak into the sealed space. The gas sensor 204 detects the change in gas concentration, thus determining that the packaging bag is damaged. If damage is detected, the controller controls the hydraulic rod 601 to push the push plate 602, pushing the damaged packaging bag to the guide plate 3, and finally it falls into the collection box 4. If not... Even if damaged, the packaging bag continues to be transported with the conveyor 1, completing the normal flow. By pressing to detect gas leaks within the sealed space, the damage to the packaging bag can be identified, avoiding misjudgments caused by visual errors. From transportation and testing to sorting, each link is linked with controllers and electronic devices to achieve automated operation, reduce manual intervention, and improve testing efficiency. The cooperation of the pusher group 6, guide plate 3, and collection box 4 can quickly separate damaged packaging bags, ensuring the quality of subsequent products and facilitating centralized processing of damaged products. The support legs at the bottom of the conveyor 1 ensure stable operation of the equipment, and the sealing strip 7 design of the sealing cover 201 enhances the sealing of the testing environment and improves testing reliability.

[0035] In this embodiment of the utility model, a rotating rod 603 is provided through both ends of the push plate 602. The rotating rod 603 is movably connected to the push plate 602, and a motor 604 is fixedly installed at one end of the rotating rod 603. Two railings 605 are nested on the outer surface of the rotating rod 603, and the two railings 605 are respectively located on both sides of the push plate 602. A positioning plate 606 is fixedly installed on both sides of the push plate 602. The positioning plate 606 is located below the two railings 605. After the two railings 605 are rotated, their bottoms contact the upper end of the positioning plate 606. The two railings 605 are located on both sides of the guide plate 3. The bottom of the guide plate 3 is inclined, and the top of the collection box 4 contacts the bottom of the guide plate 3. The bottom of the collection box 4 is equipped with universal wheels, and the upper end of the sealing strip 7 is fixedly installed with a connecting block 701. The sealing strip 7 is hollow inside, and a protrusion 702 is provided on the inner side of the sealing strip 7. The protrusion 702 is inclined. The bottom of the sealing cover 201 is provided with a slot 206. The connecting block 701 and the protrusion 702 can be embedded in the slot 206. The slot 206 fits with the connecting block 701 and the protrusion 702 respectively. The sealing strip 7 and the sealing cover 201 are detachably connected. The limit frame 5 is provided with a groove 501 on one side. The hydraulic rod 601 is installed in the groove 501. One side of the push plate 602 is attached to one side of the limit frame 5.

[0036] When hydraulic rod 601 pushes push plate 602, motor 604 drives rotating rod 603 to rotate, causing the two railings 605 to change from the retracted state (contacting positioning plate 606) to the extended state, thus limiting the damaged packaging bag on both sides and preventing it from shifting during the pushing process, ensuring accurate sliding of the guide plate 3. After pushing is completed, motor 604 reverses, railings 605 retract, and push plate 602 resets. When sealing cover 201 descends, connecting block 701 and protrusion 702 of sealing strip 7 are embedded in slot 206, forming a double-fit structure, enhancing the sealing performance between sealing cover 201 and transport platform 1. The detachable design facilitates maintenance and replacement of sealing strip 7. The inclined protrusion 702 on the inner side of sealing strip 7 can further fit the top of the packaging bag, optimizing the sealing effect. The bottom of guide plate 3 is inclined, and the top of collection box 4 contacts the bottom of guide plate 3, allowing the damaged packaging bag to slide into the collection box along guide plate 3. The universal wheels at the bottom of the collection box 4 facilitate its movement and centralized handling of damaged goods. The unfolding and retracting of the railing 605 limits and pushes the damaged packaging bags, preventing them from falling or shifting during the pushing process, thus improving the accuracy and stability of sorting. The detachable design makes the maintenance and replacement of the sealing strip 7 more convenient. The double fit of the connecting block 701, the protrusion 702 and the slot 206, as well as the inner inclined protrusion 702, greatly improves the sealing performance of the sealing cover 201, ensuring the accuracy of gas detection and reducing the false judgment rate. The universal wheels allow the collection box 4 to move flexibly, facilitating timely cleaning of damaged goods and improving the continuity of the production process. The hydraulic rod 601 is installed in the groove 501 of the limit frame 5, so that one side of the push plate 602 fits against one side of the limit frame 5, optimizing the compactness of the equipment structure, reducing space occupation, and at the same time protecting the hydraulic rod 601.
