Description

Technical Field

[0001] The utility model belongs to the technical field of packaging box quality inspection, and in particular relates to a packaging paper aluminum layer bonding quality inspection device. Background Art

[0002] In situations where exquisite printing and high-quality appearance are required, transfer-type box packaging paperboard is mostly used to make packaging boxes. At present, the production and processing flow of transfer-type box packaging paperboard is as follows:

[0003] First, make transfer card paper: after the aluminum layer of the PET transfer film is coated with transfer glue, it is cold-laminated with the front side of the white card base paper coated with back coating liquid under a certain pressure, and then it is dried in an oven and cooled by a condensing roller before entering the winding device to form a roll semi-finished product, and then transferred to the next peeling, rewinding and cutting process to make roll products of different specifications; then it is printed, hot-stamped, and die-cut to emboss into a single box wrapping paper.

[0004] The production process of transfer-type box paperboard determines that there will be a quality risk of dealumination due to insufficient firmness of the aluminum layer, but it is impossible to quickly and intuitively discover and deal with it during the production stage of transfer paperboard. It is often not until entering the molding section, after equipment embossing and machine friction, that the dealumination white spot problem caused by the poor firmness of the aluminum layer and the original paper surface is revealed. At this time, the processing has completed the last process and the problematic product has been completed. Therefore, it is necessary to test the semi-finished products before printing, and detect the problematic semi-finished products in time to prevent them from flowing into the subsequent processes. On the one hand, it reduces the product quality risk, and on the other hand, it reduces the material, energy, manpower and other costs invested in the problematic semi-finished products.

[0005] At present, most of the methods are to cut a section of samples from each roll of semi-finished products, send them to the quality inspection department, and use tools to manually scrape them to test the firmness of the aluminum layer. However, there is a problem that the consistency of manual force is easily affected, which may affect the test results. Utility Model Content

DETAILED DESCRIPTION

[0027] like Figure 1-5 As shown, the utility model provides a packaging paper aluminum layer adhesion quality detection device, comprising: a detection platform plate 10, at least two leveling rollers 20 arranged above the detection platform plate 10, and a scraping mechanism 30 arranged on the detection platform plate 10, and a sample 51 to be tested passes between the detection platform plate 10 and the leveling roller 20; the scraping mechanism 30 comprises a fixed frame 31, an elastic connecting member 32 arranged on the fixed frame 31, and a scraping body 33 arranged on the elastic connecting member 32, and the elastic connecting member 32 relies on its own elastic force to make the scraping body 33 contact the sample 51.

[0028] Compared with the prior art, the packaging paper aluminum layer bonding quality inspection device provided by the utility model allows the sample 51 to pass through the bottom of the flattening roller 20 on one side. Since the scraper 33 is connected to the elastic connector 32, it can be lifted to allow the sample 51 to pass smoothly, and then pass through the bottom of the flattening roller 20 on the other side, or not. The sample 51 is pulled by external force, and the sample 51 is rubbed against the scraper 33 against the detection platform plate 10. The aluminum removal after scraping is observed to determine whether it is qualified. Since the friction of each sample 51 through the scraper 33 is relatively consistent, it is not easy to have an adverse effect on the test result, and it can more truly reflect the quality of the product. In addition, many samples 51 can be neatly pasted on the flexible belt, and the flexible belt is continuously pulled by external force, and the samples 51 are rubbed against the scraper 33 one after another, so that a large number of samples 51 can be detected quickly, thereby improving the detection efficiency.

[0029] It should be noted that the flexible tape can be a paper tape or a plastic tape. After the samples 51 are pasted in batches, they can be rolled into a roll and put on the rotating roller during testing.

[0030] In this embodiment, a limiting plate 311 is disposed on the fixing frame 31 , the elastic connecting member 32 passes through the limiting plate 311 , and the telescopic portion of the elastic connecting member 32 abuts against the top surface of the limiting plate 311 .

[0031] Specifically, the fixing frame 31 is made of bent sheet metal, spans the long plate-shaped detection platform plate 10 and is fixed by bolts or welding. The limiting plate 311 is flat and is the middle layer structure of the fixing plate. The elastic connecting member 32 passes through the limiting plate 311 and abuts against it at the same time, which can better limit the distance between the scraping body 33 and the detection platform plate 10, improve the stability of the friction generated by the contact between the scraping body 33 and the sample 51, and is beneficial to detect whether the sample 51 is qualified.

[0032] In one embodiment, see Figure 3 The limiting plate 311 is provided with a screw hole, and an external threaded sleeve 34 is screwed into the screw hole. The telescopic part of the elastic connector 32 is inserted into and abuts against the external threaded sleeve 34. In this way, by rotating the external threaded sleeve 34, the distance between the top of the external threaded sleeve 34 and the limiting plate 311 can be changed. When the telescopic part of the elastic connector 32 abuts against the top of the external threaded sleeve 34, the distance between the scraping body 33 and the detection platform plate 10 is adjusted, so that the degree of scraping of the sample 51 can be adjusted, and samples 51 of different thicknesses can be detected.

[0033] Further, a nut 35 is screwed on the external thread sleeve 34. After adjusting the distance between the top of the external thread sleeve 34 and the limit plate 311, the nut 35 is screwed on the external thread sleeve 34 above the limit plate 311 to tighten the external thread sleeve 34 and prevent the external thread sleeve 34 from loosening due to mechanical vibration.

[0034] In this embodiment, please refer to Figure 4 The elastic connecting member 32 includes: a guide sleeve 321, an adjusting rod 322 screwed to the guide sleeve 321, a movable gasket 323 rotatably connected to the connecting rod, a spring 324 arranged at the bottom of the movable gasket 323, and a movable connecting rod 325 abutting against the end of the spring 324, and the movable connecting rod 325 is rigidly connected to the scraping body 33.

[0035] Specifically, the fixing frame 31 is provided with a mounting hole (not shown) coaxial with the screw hole on the limiting plate 311, the mounting hole is a screw hole or a through hole with a plain wall, the guide sleeve 321 is fixed in the mounting hole by screw connection or welding, the interior of the guide sleeve 321 is a screw hole, a larger diameter inner hole and a smaller diameter inner hole from top to bottom, the movable gasket 323 and the spring 1 324 are arranged in the larger diameter inner hole, the movable gasket 323 is in the shape of a circular plate, the edge of which is in clearance with the inner hole wall, and the movable connecting rod 32 5 is provided with a convex ring that abuts against a spring 1 324, and the upper end of the movable connecting rod 325 passes through an inner hole with a smaller diameter and abuts against the spring 1 324. The movable gasket 323 is moved by rotating the adjusting rod 322 to control the compression amount of the spring 1 324, so that the scraping body 33 produces different forces on the sample 51, thereby controlling the scraping force, which is used to simulate the convexity of the aluminum layer of the transfer-type box package cardboard and the equipment, the friction during the machine, and the friction between the products, which can be closer to the dealuminization of the product during actual production.

[0036] Furthermore, a second spring 326 is sleeved on the portion of the adjusting rod 322 located at the outer end of the guide sleeve 321, and the elastic force of the second spring 326 can enable the thread of the adjusting rod 322 and the screw hole of the guide sleeve 321 to generate a continuous axial force, thereby effectively reducing the probability of accidental loosening of the adjusting rod 322.

[0037] Furthermore, a rotating cap 327 is provided at the end of the adjusting rod 322 to facilitate turning the adjusting rod 322 manually or with a wrench.

[0038] In one embodiment, a limit ring 328 is provided on the movable connecting rod 325. The limit ring 328 enables the movable connecting rod 325 to abut against the external threaded sleeve 34. In some embodiments, the limit ring 328 can be replaced by protrusions distributed circumferentially around the movable connecting rod 325. In other embodiments, a structure in which the diameter of the lower part of the movable connecting rod 325 is smaller than the diameter of the upper part can also be designed to abut against the top surface of the external threaded sleeve 34.

[0039] In one embodiment, the end shape of the scraping body 33 is an axe-blade structure or a trapezoidal strip structure; the scraping body 33 with a trapezoidal strip structure, the surface in contact with the sample 51 can be designed to have a variety of roughness to simulate the friction occurring in different production stages; in another embodiment, the scraping body 33 includes a mounting frame 331 and a pressure roller 332 with a concave and convex surface rotatably connected to the mounting frame 331, when the sample 51 moves, the pressure roller 332 is driven to rotate, and the sample 51 is simultaneously subjected to the effects of sliding and rolling friction, so that the firmness of the aluminum layer can be more fully detected.

[0040] In one embodiment of the utility model, the packaging paper aluminum layer bonding quality inspection device also includes a power reel 40 disposed at one end of the inspection platform plate 10, and the power reel 40 reels the samples 51 that pass through the scraping mechanism 30. When in use, the batch of samples 51 are marked with serial numbers, and the batch of samples 51 are pasted on the flexible belt. After the flexible belt is assembled on the inspection device, its end is fixedly connected to the power reel 40. When the power reel 40 rotates, the batch of samples 51 are sequentially passed through the scraping body 33 for inspection, and then through the scraping body 33, the quality of different batches of samples 51 can be observed on the inspection platform plate 10, and the samples reeled on the power reel 40 can be removed for inspection later, which greatly improves the inspection efficiency and the consistency of the scraping force, and can also be checked and recorded by visual inspection equipment.
