Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a food can lid edge sealing detection device. Background Technology

[0002] In the food processing industry, the sealing performance of food cans is directly related to the shelf life, safety, and quality stability of food. The sealing effect between the can lid and the edge of the can body is the key factor that determines the overall sealing performance of the food can. Therefore, accurate and efficient testing of the sealing performance of the edge of the food can lid is an indispensable and important process in the food production process.

[0003] Current sealing inspection devices mostly use fixed clamps for positioning can lids. These clamps are custom-designed for cans of a specific diameter. However, on the same production line, it may be necessary to switch from an 80mm diameter can to a 100mm diameter can. Existing fixed clamps have obvious limitations. Because the clamps have a fixed structure, they cannot adapt to the size requirements of different can sizes. Every time the can type is changed, the original clamps need to be disassembled and a new clamp matching the new can type needs to be installed. This process is not only cumbersome and time-consuming, but also seriously affects the switching efficiency of the production line. Therefore, it is necessary to design a food can lid edge sealing inspection device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a food can lid edge sealing detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a food can lid edge sealing detection device, comprising a first support member, which cooperates with a drive assembly to drive two sets of slides to move relative to or towards each other. Each set of slides is detachably connected to a set of second support members. The two sets of second support members are arranged in a mirror image, and a set of clamping blocks is movably connected to each of their opposite sides. The clamping openings at both ends of each set of clamping blocks are of different sizes. At the same time, the clamping blocks can be locked by a spring locking assembly, thereby achieving stable clamping of cans of different specifications.

[0006] Preferably, the spring locking assembly consists of a positioning plate, a positioning hole, a spring, and a locking tongue. Each set of positioning plates is installed at both ends of the shaft of each set of clamping blocks. The positioning hole is provided on the side wall of each set of second support members. The spring is installed in the inner cavity of the positioning hole. The free end of the spring is connected to the locking tongue. The locking tongue can be inserted into the positioning plate to achieve locking.

[0007] Preferably, the end of the second support member away from the clamping block is connected to the slide in a plug-in manner, and after insertion, it is detachably locked by a bolt. The bolt is threaded to one side of the slide and can penetrate the second support member.

[0008] Preferably, the drive assembly includes an electric push rod and a limiting seat. The opposite sides of the two sets of slides are respectively connected to the output end of one set of electric push rods, and the other ends of the two sets of electric push rods are connected to the limiting seat installed at the center of the inner cavity of the first support member.

[0009] Preferably, the bottom end of the limiting seat is equipped with a set of visual inspection modules for detecting the sealing performance of the can lid.

[0010] Preferably, four sets of rectangularly distributed connecting ears are installed on the outer wall of the first support member.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model eliminates the need to disassemble and replace the clamps.

[0016] 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. Example

[0017] Please refer to Figure 1-5 As shown, this utility model provides a food can lid edge sealing detection device, including a first support member 1. The first support member 1 cooperates with the drive assembly to drive two sets of slides 2 to move relative to each other or towards each other. Each set of slides 2 is detachably connected to a set of second support members 3. The two sets of second support members 3 are arranged in a mirror image, and a set of clamping blocks 4 are movably connected to the opposite side of each set of clamping blocks 4. The clamping openings at both ends of each set of clamping blocks 4 are of different sizes. At the same time, the clamping blocks 4 can be locked by a spring locking assembly, thereby achieving stable clamping of cans of different specifications.

[0018] The first support 1 works in conjunction with the drive assembly to drive the two sets of slides 2 to move relative to or towards each other, thereby moving the two sets of mirror-set second support 3 to move and clamp the can lid with the clamping block 4. By utilizing the different sizes of the clamping openings at both ends of the clamping block, the clamping block 4 can be rotated to adjust to the size of the can to be tested. Then, the clamping block 4 is locked by the spring locking assembly. Finally, the drive assembly makes the two sets of clamping blocks 4 stably clamp the can lid, thus completing the positioning of the can lid.

[0019] No disassembly or replacement of the clamps is required. The clamping jaws are adjusted and locked simply by rotating the clamping blocks, simplifying the operation process, saving labor time, and adapting to different can sizes, such as diameters from 80mm to 100mm. This improves the versatility of the equipment, increases the efficiency of can type switching on the production line, and reduces production stoppages caused by changing clamps.

[0020] Specifically, the spring locking assembly consists of a positioning plate 5, a positioning hole 6, a spring 7, and a locking tongue 8. A positioning plate 5 is installed at each end of the shaft of each set of clamping blocks 4. A positioning hole 6 is provided on the side wall of each set of second support members 3. A spring 7 is installed in the inner cavity of the positioning hole 6. The free end of the spring 7 is connected to the locking tongue 8. The locking tongue 8 can be inserted into the positioning plate 5 to achieve locking. The end of the second support member 3 away from the clamping block 4 is connected to the slide 2 by a plug-in connection. After insertion, it can be detachably locked by a bolt 9. The bolt 9 is threaded to one side of the slide 2 and can penetrate the second support member 3.

[0021] The first support 1 cooperates with the drive assembly to drive the two sets of slides 2 to move relative to or towards each other, thereby moving the two sets of mirror-set second support 3. The clamping block 4 is rotated, and by utilizing the different sizes of its two ends, it is adjusted to match the type of can to be tested. At this time, the spring 7 in the positioning hole 6 pushes the locking tongue 8 into the positioning plate 5, thus locking the clamping block 4. If the existing clamping block 4 cannot be adapted, the bolt 9 is removed, the second support 3 is pulled out from the slide 2, and the adapted second support 3 and clamping block 4 are replaced. The slide 2 is then inserted again and locked by the bolt 9. Finally, the drive assembly enables the two sets of clamping blocks 4 to stably clamp the can lid for sealing testing.

[0022] The clamping block 4 is quickly locked by the spring locking assembly to ensure clamping stability. The clamping jaw can be adjusted by rotating the clamping block 4 to adapt to some different can sizes. The operation is simple and saves switching time. The second support 3 and clamping block 4 can be replaced by removing the bolt 9 to adapt to two other can sizes, further improving the adaptability of the device and meeting more production needs. There is no need to replace the entire clamp, which reduces equipment costs and maintenance difficulty and improves the flexibility of the production line.

[0023] The drive assembly includes an electric push rod 10 and a limiting seat 11. The opposite sides of the two sets of slides 2 are respectively connected to the output end of one set of electric push rods 10. The other ends of the two sets of electric push rods 10 are connected to the limiting seat 11 installed at the center of the inner cavity of the first support member 1. The bottom end of the limiting seat 11 is equipped with a set of vision inspection modules 12 for detecting the sealing performance of the can lid. Four sets of rectangular connecting ears 13 are installed on the outer wall of the first support member 1.

[0024] When the electric push rod 10 is running, it can drive the two sets of sliding seats 2 to move relative to each other, and cooperate with the second support 3 and the clamping block 4 to achieve the clamping or releasing action of the can lid. The limiting seat 11 plays a role in fixing and limiting the electric push rod 10 to ensure its stable operation. After the can lid is clamped in place, the vision detection module 12 is activated. It uses a high-definition camera to collect images of the surface and edge of the can lid, focusing on capturing image information of key parts such as the contact area between the can lid and the can body and the distribution area of ​​the sealing ring. The image recognition algorithm built into the module analyzes the collected images to determine whether there are gaps in the can lid, whether the sealing ring is intact, and whether there are foreign objects blocking the sealing surface. If no problems affecting the sealing are found in the image, the can lid is judged to be qualified for sealing. Conversely, if there are gaps, damaged rings, etc., the sealing is judged to be unqualified. The detection results can be fed back to the relevant control system for subsequent processing. The four sets of connecting ears 13 on the outer wall of the first support 1 can be used with screws and other fasteners in the prior art to fix the component to other parts to ensure the stability of the overall structure during operation.

[0025] The electric push rod 10 drives the slide block 2 to automate the operation of the can lid, reducing manual intervention and improving work efficiency. The vision inspection module 12 can accurately detect the can lid's sealing performance, which is more reliable than manual inspection, reduces the missed detection rate, and ensures product quality. The limit seat 11 fixes and limits the electric push rod 10, enhancing the stability and accuracy of the component's movement and extending the equipment's service life. Four sets of rectangularly distributed connecting ears 13, along with screws and other fasteners, facilitate the connection and fixation of this component with other existing parts, making installation convenient, highly adaptable, and saving installation time and costs.

[0026] Working principle: When the electric push rod 10 is running, it can drive the two sets of slides 2 to move relative to each other. In conjunction with the second support 3 and the clamping block 4, it can clamp or release the can lid. Rotate the clamping block 4 and use the different sizes of the clamping openings at both ends to adjust it to match the type of can to be tested. At this time, the spring 7 in the positioning hole 6 pushes the locking tongue 8 to insert into the positioning plate 5, thus locking the clamping block 4. If the existing clamping block 4 cannot be adapted, remove the bolt 9, pull the second support 3 out of the slide 2, replace it with a suitable second support 3 and clamping block 4, and then insert it into the slide 2 and lock it with the bolt 9. Finally, the drive assembly makes the two sets of clamping blocks 4 stably clamp the can lid for sealing test.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
