Description

Technical Field

[0001] The utility model relates to the technical field of can production, in particular to a pinhole detection device for a finished can body. Background Art

[0002] Cans are made of two materials: aluminum and tinplate. The lid itself is processed to form a rivet, then a pull tab is added, riveted, and then scored to create a complete lid. As a storage device, cans are hygienic, rust-resistant, and easy to open, requiring no tools. Once opened, the lid is destructible, effectively preventing theft. They offer excellent cushioning, shock absorption, heat insulation, moisture resistance, and chemical resistance. They are also non-toxic, non-absorbent, and dust-resistant, with excellent sealing properties. Stainless steel shot cans can be customized to meet specific requirements, including heat resistance, boiling resistance, and alcohol resistance. Designs can include color printing, embossing, and milling. The inner padding utilizes specialized epoxy materials and advanced production processes, ensuring excellent sealing after sealing. The lid's larger surface allows for printing various logos and designs, enhancing the aesthetics of the cap and adding value to the canned product.

Support plate 2 is fixedly connected to the inner wall of housing 1, illumination lamp 3 is fixedly connected to the top inner wall of housing 1, light sensor 4 is fixedly connected to the bottom inner wall of housing 1, and control rod 5 is slidably connected to the top of support plate 2, and the left side of control rod 5 extends to the outside of housing 1.

[0029] There are two fixing sleeves 13, and the two fixing sleeves 13 are symmetrically slidably connected to the top of the support plate 2;

[0030] The control mechanism is connected to the fixing sleeve 13 and is used to drive the fixing sleeve 13 to move forward and backward.

[0031] By means of the above mechanism: the tank body is conveniently fixed by the fixing sleeve 13, the pinhole detection of the tank body is conveniently performed through the cooperation of the irradiation lamp 3 and the light sensor 4, and the control mechanism is conveniently driven by the control rod 5 to move the fixing sleeve 13, thereby fixing or unlocking the tank body.

[0032] As a preferred solution of the present invention, the control mechanism includes a push plate 6, two push rods 9 and two cross plates 10; the push plate 6 is slidably connected to the top of the support plate 2, and the left side of the push plate 6 is fixedly connected to the right side of the control rod 5, the two push rods 9 are symmetrically rotated and connected to the top of the push plate 6, the two cross plates 10 are symmetrically slidably connected to the top of the support plate 2, and the tops of the two cross plates 10 are rotatably connected to the bottoms of the corresponding push rods 9, the sides of the two cross plates 10 that are close to each other are respectively fixedly connected to the sides of the two fixed sleeves 13 that are away from each other, and the lateral movement of the push plate 6 will push the two push rods 9. At this time, the movement of the two push rods 9 will push the two cross plates 10 to move to the side away from each other, and the movement of the cross plate 10 will drive the fixed sleeve 13 to move.

[0033] As a preferred solution of the present invention, a fixing frame 7 is fixedly connected to the top of the support plate 2, and the fixing frame 7 passes through the push plate 6. The fixing frame 7 is used to limit the push plate 6 so that the push plate 6 can only slide left and right.

[0034] As a preferred solution of the present invention, a push spring 8 is fixedly connected to the left side of the fixing frame 7, and the left side of the push spring 8 is fixedly connected to the right side of the push plate 6. The elastic force of the push spring 8 facilitates the push plate 6 to move left and reset.

[0035] As a preferred solution of the present invention, the top of the support plate 2 is symmetrically fixedly connected to the limiting plate 11, and the number of the limiting plates 11 is four. The left and right sides of the two horizontal plates 10 are slidingly connected to one side of the corresponding limiting plate 11. The limiting plate 11 is used to conveniently limit the horizontal plate 10 so that the horizontal plate 10 can only move forward and backward.

[0036] As a preferred solution of the present invention, the two horizontal plates 10 are fixedly connected to the limiting springs 12 on the sides away from each other, and the two limiting springs 12 are fixedly connected to the inner wall of the outer shell 1 on the sides away from each other. Through the elastic force of the limiting springs 12, the two horizontal plates 10 are conveniently pushed to drive the fixing sleeves 13 to move toward the side close to each other.

[0037] It should be noted that the specific types of illumination lamps 3, light sensors 4 and photosensors to be used are selected by relevant technical personnel familiar with the field, and the above-mentioned illumination lamps 3, light sensors 4 and photosensors are all existing technologies and will not be elaborated in this solution.

[0038] The working principle of the present utility model is as follows: when it is necessary to perform pinhole detection on the product can body, the shell 1 is opened first, and the control rod 5 is pushed to the right at this time. When the control rod 5 moves, it pushes the push plate 6, and the lateral movement of the push plate 6 compresses the push spring 8 and pushes the two push rods 9. At this time, the movement of the two push rods 9 pushes the two cross plates 10 to move away from each other. The movement of the cross plate 10 compresses the limit spring 12. At the same time, the movement of the cross plate 10 drives the fixed sleeve 13 to move. At this time, the can body to be inspected can be placed on the top of the support plate 2 and the can body is located between the two fixed sleeves 13. At this time, the control rod 5 is released, the push spring 8 loses its restriction and pushes the push plate 6 to the left. When the push rod 6 moves, the limit spring 12 is compressed. At the same time, the movement of the cross plate 10 drives the fixed sleeve 13 to move. When the plate 6 moves, it will drive the control rod 5 to move left. At this time, the control rod 5 is reset, and the push plate 6 will pull the push rod 9. At this time, the two limit springs 12 lose their restrictions and push the two horizontal plates 10 to move toward each other. The movement of the horizontal plate 10 will drive the fixed sleeve 13 to move, and the tank body will be fixed by the fixed sleeve 13. At this time, the shell 1 is closed and the irradiation lamp 3 is turned on. The inner wall of the fixed sleeve 13 is provided with a photosensor. The tank body is detected by the cooperation of the photosensor and the light sensor 4. When the photosensor and the light sensor 4 receive light, the resistance value of the photoresistor in the photosensor and the light sensor 4 will change, thereby judging whether there is a pinhole in the product tank body.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
