[0025] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model will be further described.

[0026] As Figures 1-5 shown, an aluminum foil heat seal detection device includes:

[0027] A support frame 5, on which a conveying unit 2 is symmetrically arranged. The conveying unit 2 includes a first bracket 21, a second bracket 22, and a conveyor belt 24 arranged between the first bracket and the second bracket 22. Guide plates 7 are arranged on both the first bracket 21 and the second bracket 22;

[0028] A transmission unit 6, which is arranged on the support frame 5 and cooperates with the conveyor belt 24;

[0029] A sorting unit 3, which is arranged on the guide plate 7. The sorting unit 3 includes a support block 33, a rotary cylinder 32, a rotating plate 35, and limit rods 34 symmetrically arranged on the rotating plate 35. An infrared thermal imager 31 is arranged on one side of the rotating plate 35, and a telescopic cylinder 39 is slidably arranged on the other side thereof. The rotary cylinder 32 is arranged on the support block 33 and cooperates with the rotating plate 35.

[0030] Specifically, the material is a packaging product made of aluminum foil. The material is placed vertically on the conveyor belt 24 for conveying until it contacts the output rod of the output cylinder. The infrared thermal imager 31 is used to detect the sealing performance of the material. If it is qualified, a signal will be sent to the telescopic cylinder 39 to retract its output rod, so that the material is conveyed to the packaging process along the F end of the conveyor belt 24. When it is unqualified, a signal will be sent to the rotary cylinder 32 to flip the material by 90°, so that the material is horizontally located at the E end of the conveyor belt 24 and conveyed into the scrap hopper 4 for storage (as Figure 2 shown), and one side of the rotating plate 35 refers to Figure 3 the left side, that is, the position of the infrared thermal imager 31, and the other side refers to Figure 3 the right side, that is, the position of the telescopic cylinder 39.

[0031] As a further embodiment provided by the present utility model, a chute is provided on the turnover plate 35, a spring 38 for pulling back the telescopic cylinder 39 is arranged in the chute, and contact switches 36 matched with the telescopic cylinder 39 are arranged on both sides of the chute. When the conveyor belt 24 conveys materials, the materials will contact the output rod of the telescopic cylinder 39. Under the continuous push of the conveyor belt 24, the pushing force is greater than the elastic pulling force of the spring 38, so that the telescopic cylinder 39 disengages from the contact switch 36. At this time, the infrared thermal imager 31 is started to detect the sealing performance of the materials.

[0032] As a further embodiment provided by the present utility model, a third bracket 65 is clamped between the supports 5. A second screw rod 66 threadedly connected with the second bracket 22 is rotatably arranged on the third bracket 65. Driving rollers 1 rotating on the first bracket 21 are symmetrically arranged on the conveying unit 2. The second bracket 22 is located on the driving roller 1 and slides. Rotating the second screw rod 66 to drive the two second brackets 22 to slide relatively or towards each other on the driving roller 1, so as to adjust the distance between the second bracket 22 and the first bracket 21, so that the device can adapt to materials of different sizes, improve the adaptability of the device, and the sorting unit 3 also changes correspondingly with the size of the materials after relative adjustment.

[0033] As a further embodiment provided by the present utility model, an adjusting wheel 67 is arranged on the second screw rod 66. Square grooves are arranged in a circumferential array on the adjusting wheel 67. The square grooves improve the friction with the hand, making the rotation of the adjusting wheel 67 more precise.

[0034] As a further embodiment provided by the present utility model, a motor 64 is arranged on the support 5. A rotating shaft 641 is arranged at the output end of the motor 64. Synchronous wheels 25 are symmetrically arranged on both the rotating shaft 641 and the driving roller 1. A conveyor belt 24 is arranged between the synchronous wheels 25. The model of the motor 64 is: MHMF042L1U2M2. Using the motor 64 as a power source for output, the conveyor belt 24 is driven to move through the synchronous wheels 25.

[0035] As a further embodiment provided by the present utility model, a first screw rod 63 is rotatably arranged on the support 5. Guide blocks 62 are symmetrically threadedly connected to the first screw rod 63. Tension rods matched with the conveyor belt 24 are arranged on the guide blocks 62. Rotating the first screw rod 63 to drive the two guide sliders to slide relatively or towards each other on the support 5, that is, adjusting the distance between the two tension rods, so as to adjust the tension of the conveyor belt 24.

[0036] In the embodiment of the present utility model, waste hoppers 4 are arranged on the first bracket 21 and the second bracket 22. An arc-shaped baffle 23 is arranged between the waste hopper 4 and the guide plate 7. The arc-shaped baffle 23 has the effect of blocking unqualified materials, so that they can better enter the waste hopper 4.

[0037] As a further embodiment provided by the present utility model, a square opening 71 is formed in the guiding plate 7, and the sorting unit 3 is located on the square opening 71. The square opening 71 is provided to enable the rotary cylinder 32 to rotate the material, reducing the obstruction during the rotation of the material.

[0038] As a further embodiment provided by the present utility model, a friction wheel 72 is provided at the square opening 71 of the guiding plate 7. When the rotary cylinder 32 drives the material to flip 90° and fit with the guiding plate 7, the friction wheel 72 improves the conveying effect of the material, enabling it to be better conveyed from the conveyor belt 24 into the waste hopper 4.

[0039] Working principle: Place the material on the conveyor belt 24. Subsequently, the motor 64 operates to drive the synchronous wheel 25 to rotate through the rotating shaft 641, thereby driving the conveyor belt 24 to operate and convey. When the material is conveyed to contact the telescopic cylinder 39, it will cause the telescopic cylinder 39 to disengage from the proximity switch 36. At this time, the infrared thermal imager 31 operates to detect the sealing of the material. When the sealing of the material is qualified, the telescopic cylinder 39 receives a signal and the output rod retracts, enabling the material to be normally conveyed on the conveyor belt 24. The F end of the conveying unit 2 outputs to the subsequent packaging process. When the sealing of the material is unqualified, the rotary cylinder 32 will receive a signal and rotate, causing the material to rotate and fit with the guiding plate 7 for conveying until it is conveyed from the E end into the waste hopper 4 for storage, facilitating the subsequent operation of re-sealing and pressure application, thereby improving the detection effect and efficiency of the material.
