[0001] The utility model relates to the technical field of package leakage detection, in particular to a roof-type package box sealing detection device. Background Art

[0002] In order to prevent external air and bacteria from invading the packaging box and causing pollution, the box body needs to be sealed during the packaging box manufacturing process, and it can only be put on the market after passing the inspection. For example, in the manufacturing process of roof-shaped dairy product packaging boxes, after the box gluing process, the hot-melt sealing edge of the packaging box needs to be leak-tested to avoid pollution and economic losses caused by leakage of the dairy product packaging box. The existing sealing detection method is manual sampling, which requires the detection worker to avoid the hot-melt sealing edge of the packaging box, cut the packaging box to be tested with a cutting knife, and then repeatedly apply the leakage detection liquid to the hot-melt sealing position of the packaging box. Finally, under the illumination of the light, observe the leakage of the hot-melt sealing position of the packaging box. This detection method has a large workload, is easy to cause visual fatigue, and has low detection efficiency. To this end, a roof-type packaging box leak detection device is developed.

[0022] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments.

[0023] like Figure 1-Figure 3 As shown, the utility model provides a sealing detection device for a roof-type packaging box 6, comprising a frame 1, a conveying platform 2 for conveying from right to left is arranged on the frame 1, and a cutting mechanism 3 and a brushing mechanism 4 are arranged above the conveying platform 2 in sequence; the hot-melt sealing edge of the packaging box 6 is parallel to the conveying direction of the conveying platform 2, and the packaging box 6 is stretched open to form a thin-walled column, and the conveying platform 2 supports the hot-melt sealing edge of the packaging box 6 to pass through the cutting mechanism 3 and the brushing mechanism 4 in sequence;

[0024] The cutting mechanism 3 includes a rotary cutter 31 and a motor 32 ; the rotary cutter 31 is used to cut the top box wall of the packaging box 6 , and the brushing mechanism 4 is used to evenly distribute the dye penetrant in the liquid storage bottle 5 on the hot-melt sealed edge of the packaging box 6 .

[0025] A light box 7 for leakage detection is arranged on the frame 1 near the end of the conveyor platform 2. After the packaging box 6 enters the light box 7, the hot-melt sealed edge and the dyed penetrant of the packaging box 6 are left to stand for a period of time. Then, under the illumination of the light box 7, the penetration condition of the hot-melt sealed edge is directly observed by naked eyes (a magnifying glass can be used for observation) to determine whether the hot-sealed edge has pores and channel defects, thereby completing the anti-leakage detection of the hot-sealed edges of the roof-type packaging boxes 6 of the same batch.

[0026] like Figure 1 As shown, the tabletop of the conveyor 2 is provided with spaced push strips 21, which push the bottom box wall edge of the packaging box 6. The push strips 21 prevent the packaging box 6 from being blocked and slipping during transportation, and ensure the smooth and reliable transportation of the conveyor 2.

[0027] like Figure 1 , Figure 2As shown, a front-to-back symmetrical baffle plate 8 is provided between the cutting mechanism 3 and the brushing mechanism 4; the baffle plate 8 is tilted from top to bottom in the conveying direction; the baffle plate 8 contacts the front and back box walls of the cut packaging box 6, so that the cut packaging box 6 is unfolded front and back; specifically, as shown in FIG. Figure 3 As shown, the push strip 21 of the conveyor platform 2 pushes the packaging box 6 to move to the baffle 8, and the baffle 8 pushes the front and rear walls of the packaging box 6 outward, and as the packaging box 6 moves, the front and rear walls of the packaging box 6 are fully unfolded, thereby preventing the walls of the packaging box 6 from blocking the brushing mechanism 4, which is conducive to the brushing mechanism 4 to accurately apply the dye penetrant.

[0028] The edge where the baffle plate 8 contacts the packaging box 6 is provided with an outwardly extending arc plate. The arc plate is provided to facilitate the baffle plate 8 to smoothly contact the packaging box 6 and guide the box wall of the packaging box 6 to unfold and flatten.

[0029] As a specific implementation of the brushing mechanism 4, the brushing mechanism 4 includes a plurality of nozzles and a delivery pump; the delivery pump supplies the dye penetrant in the liquid storage bottle 5 to the nozzle, and the outlet of the nozzle faces the delivery platform 2 below. Specifically, there is an appropriate distance between the nozzle and the delivery platform 2 for the package box 6 to pass through. When the cut package box 6 passes under the brushing mechanism 4, the dense spraying of the nozzle makes the dye penetrant evenly spread over the hot-melt edge sealing area of ​​the package box 6, avoiding the situation where the manual brushing amount and brushing position are uneven.

[0030] Preferably, the brushing mechanism 4 further comprises a brush, which is hinged between the nozzle and the light box 7 through a brush holder, and the brush is close to the table surface of the conveyor 2. After the nozzle spreads the dye penetrant all over the hot-melt edge sealing area of ​​the packaging box 6, the conveyor 2 continues to transport the packaging box 6, so that the brush contacts the hot-melt edge sealing surface of the packaging box 6, thereby brushing the sprayed dye penetrant evenly, playing a secondary brushing role, which is beneficial to the uniform distribution of the dye penetrant and improving the accuracy of the leak-proof detection of the hot-melt edge sealing.

[0031] As another specific implementation of the brushing mechanism 4, Figure 1 , Figure 2 As shown, the brushing mechanism 4 includes a rolling brush 41 with a soft surface, and the dye penetrant in the liquid storage bottle 5 flows to the rolling brush 41 through the conduit by gravity. The rolling brush 41 is soaked with the dye penetrant, and when the packaging box 6 passes through the rolling brush 41, the hot-melt sealing surface of the packaging box 6 contacts the rolling brush 41, which can drive the rolling brush 41 to rotate; through the rotation of the rolling brush 41, the dye penetrant is rolled on the hot-melt sealing area of ​​the packaging box 6.

[0032] Preferably, the brushing mechanism 4 further comprises a second motor 42, and the driving end of the second motor 42 is drivingly connected to the rotating shaft of the roller brush 41. During brushing, the second motor 42 drives the roller brush 41 to rotate, so that the roller brush 41 and the conveyor 2 convey the packaging box 6 in the same direction, and the hot-melt sealing edge of the packaging box 6 is squeezed between the roller brush 41 and the conveyor 2, which is conducive to the penetration of the dye penetrant and improves the accuracy of the leak-proof detection of the hot-melt sealing edge.
