[0035] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0036] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and embodiments.

[0037] Please refer to Figures 1 to 5 , an embodiment of the present utility model provides a container bread film hole detection device, which can detect whether there are holes in the outer packaging film of the container barrel of instant noodles in a bucket and whether the wrinkles are qualified.

[0038] A container bread film hole detection device of the present application includes a conveying mechanism 1, a clamping mechanism 2, a detection mechanism 4, and a base 8. Among them, the conveying mechanism 1, the clamping mechanism 2, and the detection mechanism 4 are all arranged on the base 8. The base 8 is built with sheet metal aluminum profiles to make the overall weight of the device light. An electric control box is arranged inside the base 8, and a control circuit board and various electrical components are installed inside the electric control box.

[0039] Preferably, the conveying mechanism 1 includes a first conveyor belt 11. The first conveyor belt 11 is a belt conveyor belt, and the first conveyor belt 11 is driven to transmit by conventional technical means in the prior art;

[0040] The clamping mechanism 2 is arranged at one end of the conveying mechanism 1 and includes two groups of clamping conveyor belts 21 arranged side by side front and back and a driving component 3 for driving the clamping conveyor belts 21 to drive. One end of the first conveyor belt 11 close to the clamping mechanism 2 is directly below the gap between the two groups of clamping conveyor belts 21. The clamping mechanism 2 is used to clamp the barrel body of the barrel to be tested and convey the barrel to the top of the first conveyor belt 11. Specifically, a second conveyor belt is arranged at one end of the clamping mechanism 2 away from the conveying mechanism 1. The second conveyor belt is installed at the rear end of the shrink film furnace. After the outer surface of the instant noodle barrel is sealed with a film, it is conveyed between the two groups of clamping conveyor belts 21 through the second conveyor belt. The clamping conveyor belt uses a sponge conveyor belt, and the sponge conveyor belt has softness, which can stably clamp the barrel to be tested without damaging the barrel film. The distance between the two groups of clamping conveyor belts 21 is slightly larger than the diameter of the middle position of the barrel to be tested. The clamping mechanism 2 clamps the middle position of the barrel to be tested, so that the bottom of the barrel to be tested is completely exposed, avoiding inaccurate detection caused by the bottom of the barrel being blocked. The driving component 3 drives the two groups of clamping conveyor belts 21 to drive, driving the barrel to be tested to move to the top of the first conveyor belt 11 for subsequent detection steps.

[0041] The detection mechanism 4 includes a bottom detection component 41, a lid detection component 42 and a body detection component 43. The bottom detection component 41 is arranged directly below the gap between the two groups of clamping conveyor belts 21 and is used to photograph the bottom of the barrel to be tested. The lid detection component 42 and the body detection component 43 are both arranged above the first conveyor belt 11 and are used to photograph the top and the body of the barrel to be tested. Specifically, when the two groups of clamping conveyor belts 21 clamp the barrel to be tested and move, the bottom of the barrel is completely exposed, and the bottom detection component 41 detects the bottom of the barrel. After the barrel to be tested is conveyed to the top of the first conveyor belt 11, under the conveyance of the first conveyor belt 11, the barrel to be tested passes through the lid detection component 42 and the body detection component 43 in sequence. The lid detection component 42 photographs and detects the top of the barrel, and the body detection component 43 photographs and detects the body (the side surface of the barrel excluding the top and the bottom). This application can perform comprehensive detection on the lid, bottom and body of the barrel to be tested, improving the detection accuracy.

[0042] In a preferred embodiment, as Figure 4As shown in the figure, the bottom barrel detection component 41 includes a bottom camera 411 and a coaxial light source 412. The bottom camera 411 is arranged directly below the gap between the two groups of clamping conveyor belts 21, and the coaxial light source 412 is arranged between the clamping conveyor belt 21 and the bottom camera 411 and directly above the bottom camera 411. Specifically, the bottom camera 411 is an industrial camera, and the coaxial light source 412 is a common coaxial light source on the market. The bottom camera 411 and the coaxial light source 412 are installed below the clamping conveyor belt 21 through a bracket. The bottom camera 411 is arranged on the backlight side of the coaxial light source 412, and the lens of the bottom camera 411 is oriented towards the coaxial light source. When the barrel to be tested passes above the top of the bottom camera 411, the bottom camera 411 takes a picture of the bottom of the barrel to obtain an image of the bottom of the barrel. The image is analyzed and processed by a vision software system to determine whether there is a hole in the bottom barrel coating. During shooting, the light source in the coaxial light source 412 is diffused through the diffuser plate arranged therein and hits the semi-transparent plate reflection beam splitter. The beam splitter reflects the light to the bottom of the barrel to be tested, and then is reflected from the bottom of the barrel into the lens of the bottom camera 411. The coaxial light source 412 has uniform brightness, making the image taken by the bottom camera 411 clearer and improving the accuracy of camera detection.

[0043] In a preferred embodiment, as Figure 4 shown, an opening surface light source 413 is arranged directly above the coaxial light source 412, and the lens of the bottom camera 411 is directly opposite the through hole of the opening surface light source 413. The opening surface light source 413 is a common LED opening surface light source on the market, and the through hole on the opening surface light source 413 does not affect the shooting of the bottom camera 411. The lens of the bottom camera 411 takes a picture of the bottom of the barrel to be tested through the through hole of the opening surface light source 413. During shooting, the opening surface light source 413 can further illuminate the bottom of the barrel to be tested, and combined with the coaxial light source 412, it provides light sources at different angles to the bottom of the barrel to be tested, improving the detection effect.

[0044] In a preferred embodiment, as Figure 2 shown, the barrel lid detection mechanism 42 includes a top camera 421 and a side illumination light source 422. The top camera 421 is arranged above the side of the first conveyor belt 11, and the side illumination light source 422 is arranged on the other side of the first conveyor belt 11. Specifically, the top camera 421 is an industrial camera, the lens of the top camera is oriented towards the top of the first conveyor belt 11, the side illumination light source 422 is a common LED light board on the market, and the side illumination light source 422 is arranged symmetrically with respect to the top camera 421. When the barrel to be tested passes through the shooting area of the top camera 421, the top camera 421 obtains an image of the top of the barrel to be tested. The image is analyzed and processed by a vision software system to determine whether there is a hole in the top barrel coating.

[0045] In a preferred embodiment, as Figure 5As shown, the barrel body detection mechanism 43 includes a camera group 431 and a top light source 432. The top light source 432 includes multiple groups of strip light sources arranged horizontally above the first conveyor belt 11. The multiple groups of strip light sources are sequentially connected end to end to form a polygon structure. The camera group 431 is arranged in a ring below the polygon structure, and the lenses of the cameras in the camera group all point directly below the polygon structure. Specifically, mounting brackets are provided on both sides of the first conveyor belt 21, and a top frame is provided between the mounting brackets. The multiple strip light sources are arranged above the first conveyor belt 11 through the top frame. The camera group 431 includes four industrial cameras, which are evenly arranged around the top light source 432, and the lenses of the four industrial cameras all point directly below the top light source 432, enabling all-round shooting of the barrel body of the to-be-tested barrel. The multiple strip light sources connected end to end to form a polygon structure can illuminate the four sides of the barrel body, facilitating the industrial cameras to clearly capture the barrel body image of the to-be-tested barrel. When the to-be-tested barrel passes below the camera group 431, the four industrial cameras shoot the barrel body of the to-be-tested barrel, obtain the barrel body image of the to-be-tested barrel, and the image is analyzed and processed by the vision software system to determine whether there are holes in the barrel body coating and whether the length and quantity of the barrel body wrinkles meet the requirements.

[0046] In a preferred embodiment, as Figure 4 shown, the driving assembly 3 includes a mounting plate 31, a synchronous pulley 32, and a motor 33. The mounting plate 31 is arranged directly above the clamping conveyor belt 21. Synchronous pulleys 32 are rotatably arranged at both ends of the bottom of the mounting plate 31. The clamping conveyor belt 21 is sleeved on the outer surfaces of the two synchronous pulleys 32. The center of any one of the synchronous pulleys 32 is connected to a motor 33 that drives it to rotate. Specifically, starting the motor 33 can drive the synchronous pulley 32 connected to it to rotate, and drive the other synchronous pulley 32 to rotate through the transmission of the clamping conveyor belt 21, thereby enabling the clamping conveyor belt 21 to be stably conveyed.

[0047] In a preferred embodiment, as Figure 3 and Figure 4As shown, the clamping mechanism 2 further includes a support frame 22, a bidirectional lead screw 23, a limiting rod 24, and two groups of moving plates 25. The bidirectional lead screw 23 and the limiting rod 24 are arranged in parallel between the support frames 22. One end of the bidirectional lead screw 23 is rotatably connected to the support frame 22, and the other end rotatably penetrates through the support frame 22 and is provided with a rotating handle 26. The two groups of moving plates 25 are fixedly connected to the two groups of mounting plates 31 in one-to-one correspondence. Threaded blocks and limiting blocks are provided on both groups of moving plates 25. The bidirectional lead screw 23 threadedly penetrates through the threaded blocks, and the limiting rod 24 slidably penetrates through the limiting blocks. Rotating the bidirectional lead screw 23 can drive the two groups of clamping belts 21 to approach or move away from each other. Specifically, under the limitation of the limiting rod 24, rotating the bidirectional lead screw 23 can make the two moving plates 25 threadedly connected to it approach or move away from each other, thereby driving the two clamping belts 21 to approach or move away from each other, facilitating adjusting the distance between the two clamping belts 21 according to the size of the barrel to be measured, so as to meet the detection of barrels with different diameters and improve the practicability of the equipment.

[0048] In a preferred embodiment, as Figure 3 and Figure 4 shown, two guide rods 27 are arranged in parallel front and back directly above the gap between the two groups of clamping belts 21. Both guide rods 27 are parallel to the clamping belts 21. Specifically, when the clamping belts 21 clamp the barrel to be measured, the top of the barrel to be measured contacts the guide rods 27. Under the guidance of the guide rods 27, the barrel body is located in a vertical plane, avoiding the barrel body from being skewed and affecting the subsequent detection effect.

[0049] In a preferred embodiment, it further includes a protective housing 7. The conveying mechanism 1, the clamping mechanism 2, and the detection mechanism 4 are all arranged inside the protective housing 7. One end of the protective housing 7 is provided with a feeding port for the barrel to be measured to enter, and the other end is provided with a discharging port for the barrel to be measured to exit; a touch screen is also installed on one side of the protective housing 7, and the touch screen is electrically connected to the control circuit board.

[0050] In a preferred embodiment, as Figure 3 and Figure 4 shown, an air gun 5 for removing unqualified barrels is arranged on one side of the first conveyor belt 11, and a discharge chute 6 that cooperates with the air gun 5 is arranged on the other side of the first conveyor belt 11. Specifically, a notch is provided on the protective housing 7 corresponding to the discharge chute 6. When any one of the cameras such as the bottom camera 411, the top camera 421, and the camera group 431 captures an abnormal image, the air gun 5 sprays gas to blow out the unqualified barrels, causing them to fall into the discharge chute 6. A collection device can be connected below the discharge chute 6, and the unqualified barrels fall into the unqualified product collection device through the discharge chute 6.
