Description

Technical Field

[0001] This utility model relates to the field of packaging paper testing technology, and in particular to a testing station for laminated paper. Background Technology

[0002] Currently, cigarette packaging is generally divided into two types: hard packaging and soft packaging. Hard-pack cigarettes are generally flip-tops. To ensure that the cigarette cap can still be completely closed with the box after being flipped back, a lining is attached to the opening of the cigarette box to hold the cap in place.

[0003] For aesthetic reasons, the collar packaging of higher-end cigarettes typically uses reflective silver laminated paper. However, during the production of this laminated paper, defects such as wrinkles and holes may occur due to raw material or processing issues, requiring inspection. Current inspection methods involve manual visual inspection under high-brightness lighting. However, because one side of the laminated paper is highly reflective, it easily forms bright spots under strong light, which, while making wrinkles and creases more obvious, severely affects the detection of holes. The current method involves flipping the laminated paper for secondary inspection, but this not only remains difficult but also easily damages the laminated paper during flipping, affecting the inspection results. Therefore, a testing station is needed that can detect wrinkles and holes without flipping the paper. Utility Model Content

[0004] The purpose of this invention is to solve at least one of the technical problems existing in the prior art by providing a testing station for film-coated paper, thereby solving the aforementioned problem.

[0005] To achieve the above objectives, a testing station for film-coated paper is provided, comprising a base support frame, a transparent worktable at the top of the base support frame, a side support frame fixedly connected to one side of the transparent worktable, a top frame fixedly connected to the top of the side support frame near the transparent worktable, a top lamp holder at the bottom of the top frame, a middle layer fixedly connected inside the base support frame below the transparent worktable, a lamp holder at the upper center of the middle layer, and a switch holder at the corner of the middle layer away from the side support frame.

[0006] According to the aforementioned testing station for film-coated paper, the top lamp holder and the lamp holder are both electrically connected to three LED tubes.

[0007] According to the aforementioned testing station for film-coated paper, the switch base is equipped with two rocker switches, and the two rocker switches are respectively electrically connected to the top lamp holder and the lamp holder.

[0008] According to the aforementioned testing station for film-applied paper, a glass plate is disposed above the transparent worktable.

[0009] According to the aforementioned testing station for film-coated paper, a reflector is provided on the side of the side support and the top frame near the transparent worktable, and the top lamp holder passes through the reflector and is fixedly connected to the top frame.

[0010] According to the aforementioned testing station for film-coated paper, the two rocker switches of the switch base are arranged in opposite states and side by side.

[0011] The above solution has at least one of the following beneficial effects:

[0012] 1. This utility model is equipped with a transparent worktable, with a top lamp holder and a lamp holder. When the film is placed on the transparent worktable, the top lamp holder and the lamp holder are activated respectively to illuminate the top and bottom of the film. This makes it easy for the staff to detect wrinkles and holes by reflecting light and transmitting light, respectively. There is no need to flip the film, which enhances the practicality of the device.

[0013] 2. The two rocker switches in the switch base of this utility model have opposite switching states and are arranged side by side. When controlling the lights, the two switches can be pressed on the same side to form parallel control, so that the detection platform can be set to either the lower light being on and the upper light being off or vice versa, avoiding mutual interference between the upper and lower lights and enhancing the practicality of the device.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] Reference Figure 1-4 This utility model provides a testing station for film-applied paper, including a base support frame 1. A transparent worktable 2 is provided on the top of the base support frame 1. A side support frame 3 is fixedly connected to one side of the transparent worktable 2. A top frame 4 is fixedly connected to the top of the side support frame 3 near the transparent worktable 2. A top lamp holder 6 is provided below the top frame 4. Reflectors 8 are provided on the sides of both the side support frame 3 and the top frame 4 near the transparent worktable 2. The top lamp holder 6 passes through the reflector 8 and is fixedly connected to the top frame 4. Inside the base support frame 1, below the transparent worktable 2, is a... The middle layer 5 has a lamp holder 7 located in the upper center of the middle layer 5. A glass plate 9 is located above the transparent workbench 2. A switch holder 10 is located at the corner of the middle layer 5 away from the side support 3. The transparent workbench 2 of this utility model, together with the top lamp holder 6 and the lamp holder 7, allows the top lamp holder 6 and the lamp holder 7 to be activated respectively when the film paper is placed on the transparent workbench 2, so that the light is provided above and below the film paper respectively by activating the top lamp holder 6 and the lamp holder 7. This makes it convenient for the staff to detect wrinkles and holes from the reflection and light transmission respectively, without having to flip the film paper.

[0024] Both the top lamp holder 6 and the lamp holder 7 are electrically connected to three LED tubes. The switch holder 10 is equipped with two rocker switches, which are electrically connected to the top lamp holder 6 and the lamp holder 7 respectively. The two rocker switches of the switch holder 10 have opposite switching states and are arranged side by side. When controlling the lights, the two switches can be pressed on the same side to form parallel control, so that the detection platform can be set to either the bottom light on and the top light off or the top light on and the bottom light off, avoiding mutual interference between the upper and lower lights.
