DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0026] Reference Figure 1-7 As shown, a gluing quality inspection device for a manual gluing machine for cigarette boxes comprises a base 1 and a detection mechanism 3, wherein the detection mechanism 3 is mounted on the base 1 and is used to inspect the gluing cigarette boxes, a conveying frame 2 is arranged at the front side of the base 1, a conveying belt 21 is mounted on the conveying frame 2, and guide plates 22 are connected to the conveying frame 2 and located on both sides of the conveying belt 21;
[0027] The detection mechanism includes multiple groups of brackets 31 and a U-shaped lifting frame 321. The multiple groups of brackets 31 are installed on the base 1. Each group of the brackets 31 is connected to a pair of mounting plates 311. A plurality of rollers 312 are rotatably connected between the pair of mounting plates 311. Multiple cylinders 32 are installed on the base 1. The movable ends of the multiple cylinders 32 are commonly connected to the lifting frame 321. A slide rail 34 is respectively arranged at both ends of the lifting frame 321. A slider 341 is slidably connected to each of the slide rails 34. A detection plate 35 is commonly connected to the two sliders 341.
[0028] In this embodiment, a plurality of rotating shafts 33 are equidistantly connected to the lifting frame 321, each of the rotating shafts 33 is coaxially connected to a material guide roller 331, and the plurality of material guide rollers 331 are respectively distributed in the gaps between two adjacent groups of brackets 31. A motor 332 is installed on the side of the lifting frame 321 away from the conveyor belt 21, and the motor 332 is coaxially connected to one of the rotating shafts 33. A sprocket 333 is coaxially connected to one end of the plurality of rotating shafts 33 away from the motor 332, and the plurality of sprockets 333 are commonly sleeved with a chain 334.
[0029] In this embodiment, the base 1 is connected to a mounting column 36, the mounting column 36 is provided with a slide groove 361, a moving rod 362 is slidably connected in the slide groove 361, the outer end of the moving rod 362 is connected to a limiting rod 37, the moving rod 362 is connected to a first straight rack 363, the mounting column 36 is connected to a second straight rack 364, and the lifting frame 321 is rotatably connected to a gear 365 via a pin shaft, and the gear 365 is meshed with the first straight rack 363 and the second straight rack 364 at the same time.
[0030] In this embodiment, the cross section of the limit rod 37 is a right-angled trapezoidal structure. The limit rod of the right-angled trapezoidal structure matches the shape of the opening 45 on the cigarette box cardboard. Elastic sheets 371 are provided on both sides of the limit rod 37 near the bottom. Each of the elastic sheets 371 is embedded with a pressure sensor. The two pressure sensors are electrically connected to the control circuits of the multiple cylinders 32. When the elastic sheets 371 on both sides of the limit rod 37 are pressurized, the multiple cylinders 32 will be controlled to start working at the same time. Even if the elastic sheets 371 are no longer pressurized, the cylinders 32 will work a complete stroke. The path of a complete stroke is that the cylinder 32 first pushes the lifting frame 321 to the highest position, then pulls the lifting frame 321 down to the lowest position, and finally rises back to the initial position. The initial position of the cylinder 32 is higher than the lowest position of the cylinder 32. When the cylinder 32 is in the initial position, the guide roller 331 is lower than the height of the roller 312. At this time, the gap between the lowest end of the limiting rod 37 and the roller 312 is greater than the thickness of one layer of cigarette box paperboard, so that the bottom layer of the folded cigarette box paperboard can pass under the limiting rod 37, and the limiting rod 37 only intercepts the upper layer of the folded cigarette box paperboard.
[0031] In this embodiment, both ends of each of the slide rails 34 are provided with limit blocks 342, a power-connecting sheet 344 and a power-connecting layer 345 are embedded on the surface of one of the slide rails 34, and a conductive sheet 343 is embedded at the bottom of the slider 341 corresponding to the slide rail 34, and the conductive sheet 343 can only contact one of the power-connecting sheet 344 or the power-connecting layer 345 at the same time. The distribution area of the power-connecting sheet 344 and the power-connecting layer 345 on the slide rail 34 is as shown in FIG. Figure 6 As shown, the slider 341 contacts the power-connecting sheet 344 only when it is close to the edge. When the slider 341 slides to the left, the power-connecting sheet will contact the power-connecting layer 345. The conductive sheet 343, the power-connecting sheet 344 and the power-connecting layer 345 are electrically connected to the motor 332 and the external power supply through wires to control the forward and reverse output of the motor 332. When the conductive sheet 343 contacts the power-connecting sheet 344, the output of the motor 332 is forward rotation, driving the guide roller 331 to rotate clockwise; when the conductive sheet 343 contacts the power-connecting layer 345, the output of the motor 332 is reverse rotation, driving the guide roller 331 to rotate counterclockwise.
[0032] In this embodiment, the base 1 is connected to a fixed column 38 located directly below the detection plate 35. The top of the fixed column 38 is provided with an inclined surface for pushing the detection plate 35 to slide and reset when the detection plate 35 descends. When the lifting frame 321 descends to the lowest position, the inclined surface on the fixed column 38 just pushes the detection plate 35 to slide forward until it is close to the edge and fits the limit block 342.
[0033] In this embodiment, a pressure sensor is provided on the material guide roller 331 , and the pressure sensor is electrically connected to the control circuit of the motor 332 , that is, when there is material on the material guide roller 331 , the motor 332 will be powered on to drive the material guide tube 331 to rotate.
[0034] The working process and principle of the present invention are as follows:
[0035] When in use, the entire device is installed at the discharge port of the manual gluer, and the conveyor belt 21 will receive the cigarette box paperboard leaving the discharge port of the manual gluer. At this time, the cigarette box paperboard is in a folded state (such as Fig. 9 As shown in the figure, after being conveyed by the conveyor belt 21 and guided by the guide plate 22, the cigarette box paperboard is kept flush and sent to the detection mechanism 3. When all the cigarette box paperboards are on the multiple rollers 312, the cigarette box paperboards will still slide on the rollers 312 with the inertia of sliding forward, and the position of the limit rod 37 just corresponds to the upper opening 45 of the folded cigarette box paperboard. As the cigarette box paperboard slides forward, the bottom end of the limit rod 37 will enter the upper opening 45 of the cigarette box paperboard, and the limit rod 37 will detect the width of the upper opening 45 of the cigarette box paperboard.
[0036] When the width of the opening 45 meets the specified range, the sliding cigarette box cardboard is intercepted and stopped by the limit rod 37 without contacting the detection plate 35. At this time, the elastic sheets 371 on both sides of the limit rod 37 will be squeezed by the outer swing cover 42 and the inner swing cover 43 of the cigarette box cardboard. The pressure sensors in the two elastic sheets 371 will control the cylinder 32 to start working for a complete stroke after being compressed. The cylinder 32 will first push the lifting frame 321 to lift upward, and the guide roller 331 will lift the cigarette box cardboard away from the roller 312 after rising. At the same time, the weight of the cigarette box cardboard will press on the guide roller 331, and the pressure sensor on the guide roller 331 will control the motor 332 to start. The width of the opening 45 is within the specified range and does not push the detection plate 35 to slide. The conductive sheet 343 on the slider 342 is in contact with the power-connecting sheet 344. After being energized, the motor 332 will output forward rotation to drive the guide roller 331 to rotate clockwise. During the rising process of the lifting frame 321, the meshing transmission between the first spur rack 363, the second spur rack 364 and the gear 365 is utilized to make the limit rod 37 rise to twice the height of the lifting frame 321. The limit rod 37 will be pulled out of the opening 45 of the cigarette box cardboard and will no longer block the sliding of the cigarette box cardboard. Driven by the guide roller 331, the cigarette box cardboard with qualified gluing quality will slide to the right and leave the detection mechanism 3.
[0037] When the width of the opening 45 is too large, the distance that the limit rod 37 extends into the opening 45 of the cigarette box paperboard will become larger, and the interception distance of the cigarette box paperboard will increase. When the elastic pieces 371 on both sides of the limit rod 37 are squeezed by the outer swing cover 42 and the inner swing cover 43 of the cigarette box paperboard, the cigarette box paperboard that has been intercepted and stopped has pushed the detection plate 35 to slide to a certain extent. After sliding, the conductive piece 343 on the slider 342 will change from contacting with the power connection piece 344 to contacting with the power connection layer 345, and the lifting frame 321 and the limit rod 37 are lifted up on the cylinder 32 to be drawn. After leaving, the energized motor 332 will reverse its output to drive the guide roller 331 to rotate counterclockwise. Driven by the guide roller 331, the cigarette box cardboard with unqualified gluing quality will slide to the left and separate from the qualified cigarette box products. The unqualified cigarette box cardboard can be reshaped before the glue dries, thereby ensuring the product quality. After the cigarette box cardboard leaves the detection mechanism 3, the cylinder 32 pulls the lifting frame 321 down to the lowest position, and resets the sliding detection plate 35 through the inclined surface on the fixed column 38, preparing for the detection of the next cigarette box cardboard.

Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
