Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carton surface film laminating, and particularly relates to a carton surface film laminating device. Background Technique
[0002] Film laminating, also known as "plastic coating", "mounting", "film pasting", etc., refers to the process of thermally pressing and laminating a transparent plastic film onto the surface of printed materials. Common film-laminated packaging products include cartons, paper boxes, handbags, fertilizer bags, seed bags, self-adhesive labels, etc. Carton film laminating can improve the protection performance, aesthetics and water resistance of cartons. During the film laminating process, quality inspection is required to ensure that the surface of the film is flat and bubble-free. However, in the actual production process, bubbles will inevitably appear, usually due to foreign objects on the surface of the carton or film, or the unevenness of the rubber roller. Therefore, the quality inspection after carton film laminating is extremely important. Existing quality inspections usually rely on visual inspection. Since the transparent film only has surface protrusions, it is very difficult to be observed by the naked eye. Moreover, during the film laminating process, the cartons are continuously conveyed. Although electro-optical devices are highly efficient, their manufacturing and operating costs are too high. There is an urgent need for a low-cost and effective quality inspection device for film production.
[0003] In view of this, we propose a carton surface film laminating device that can effectively inspect whether there are bubbles in the film-laminated cartons and reduce defective products in film laminating production. Content of the Utility Model

[0008] Preferably, a touch rod is provided at the end of the detection plate, and an angle of 75° to 100° is provided between the touch rod and the detection plate.

[0013] (III) Beneficial effects
[0014] The utility model provides a carton surface laminating device, which has the following beneficial effects:
[0015] (1) The carton surface film laminating device, through the settings of the roller and the detection frame, since the detection frame needs to be triggered by the roller to start, the detection frame will not affect the production of film laminating on the surface of the conveying device when it is not started. The roller makes the film laminating more fitting. When there are bubbles on the surface of the film laminated on the carton surface during the process of passing through the conveying device, when passing through the roller, the roller will float upward, causing the rear swing arm connected to the roller to lift up, and the detection frame to descend. The detection plate on the detection frame fits on the carton surface of the conveying device. During the movement of the bubbles on the carton surface, when touching the detection plate, the detection plate flips and drives the surface touch rod to lift up, triggering the pressure sensor switch at the bottom of the warning light, causing the warning light on the warning frame to light up, indicating to the operator that the carton surface at the bottom where the warning light is lit is uneven and has bubbles.
[0016] (2) The carton surface film laminating device, through the settings of the detection frame and the warning frame, since there are multiple detection plates on the surface of the detection frame, the multiple equally spaced detection plates enable bubbles at different positions on the carton surface to touch the corresponding detection plates. Each detection plate corresponds to a warning light. When the warning light lights up, it indicates that there are bubbles or protrusions at the bottom of the corresponding carton, enabling the production personnel to quickly find the corresponding bubbles or foreign objects, and timely adjust the equipment parameters or detect the rubber roller, reducing the occurrence of defective products.

Detailed implementation manner
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.
[0025] Please refer to Figure 1 - Figure 6 The present invention provides a technical solution:
[0026] A carton surface film laminating device, including a roller 2, a detection frame 3 and a conveying device 1. The roller 2 and the detection frame 3 are jointly installed on the surface of the conveying device 1, and the roller 2 and the detection frame 3 are drivingly connected. The film laminated carton on the surface of the conveying device 1 first passes through the roller 2 and then passes through the detection frame 3. The roller 2 makes the film on the carton surface more fitting. The roller 2 includes a roller shaft 21, and two front swing arms 22 are respectively rotatably connected to both ends of the roller shaft 21. The ends of the two front swing arms 22 are respectively connected with two groups of bridging frames 23. The other sides of the two groups of bridging frames 23 are fixed with rear swing arms 24. The ends of the two rear swing arms 24 are fixed with a lever 25. The bridging frame 23 makes the roller shaft undulate to control the up and down movement of the lever 25 through the front swing arms 22 and the rear swing arms 24 connected at both ends. The detection frame 3 includes a cross bar frame 31, and detection plates 32 are equidistantly distributed on the surface of the cross bar frame 31. A touch rod 33 is arranged at the end of the detection plate 32, and an included angle of 75° - 100° is arranged between the touch rod 33 and the detection plate 32; through the included angle between the touch rods 33, it is ensured that the touch rods 33 can effectively contact the pressure sensor switch 43 of the warning frame 4 during the up and down movement. The detection frame 3 is installed on the surface of a sleeve rod 34, and a detection control board 35 is arranged between the detection frame 3 and the sleeve rod 34. The detection control board 35 includes a rotating shaft 351. The rotating shaft 351 is installed at the top of the sleeve rod 34. A short plate 352 and a long plate 353 are arranged on the surface of the rotating shaft 351, and the short plate 352 and the long plate 353 are perpendicular to each other; the sleeve rod 34 and the detection control board 35 are supported by the short plate 352 on the surface of the rotating shaft 351. Through the support of the short plate 352, a distance is maintained between the sleeve rod 34 and the detection control board 35, so that the detection plates 32 on the surface of the movable shaft rod are kept at a distance from the film laminated carton on the surface of the conveying device 1. The detection control board 35 is cooperatively connected with the lever 25.
[0027] A warning frame 4 is arranged at the rear end of the detection frame 3. The warning frame 4 includes a lamp frame 41, warning lights 42 are arranged on the surface of the lamp frame 41, and a pressure sensor switch 43 is arranged at the bottom end of the warning lights 42; the warning lights 42 and the pressure sensor switch 43 are electrically connected; a plurality of warning lights 42 are arranged. Through the plurality of warning lights 42, the plurality of warning lights 42 are respectively arranged on the surface of the lamp frame 41, and each warning light 42 corresponds to a detection plate 32 respectively, so that each warning light 42 corresponds to a warning sign. When the corresponding warning light 42 lights up, it means that the film bulge on the carton surface is detected by the corresponding warning sign, which is convenient for production personnel to quickly find the problem point.
[0028] When the carton surface film laminating device of the present utility model is in use, the device is cooperatively installed at the end of the film laminating device. The carton after film laminating is conveyed to the bottom of the roller 2 through the conveying device 1. The flat-surfaced film-laminated carton passes through the bottom of the roller 2 on the surface of the conveying device 1. When there are foreign objects or bubbles on the surface of the carton, the roller 2 is lifted by the foreign objects on the surface, causing the front rocker arms 22 connected to both ends of the roller 2 to be lifted synchronously, so that the front rocker arms 22 drive the rear rocker arms 24 at one end of the bearing bracket to press down. The lever 25 at the end of the rear rocker arm 24 presses down the long plate 353 of the detection control board 35, causing the short plate 352 of the rotating shaft 351 at the end of the long plate 353 to flip. After there is no support of the short plate 352 between the crossbar frame 31 and the sleeve rod 34, the crossbar frame 31 descends and inserts into the inside of the sleeve rod 34, so that the detection plate 32 on the surface of the crossbar frame 31 contacts the carton on the conveying device 1. The raised bubbles collide with any one of the detection plates 32 on the detection frame 3, causing the detection plate 32 to flip around the axis, so that the contact rod 33 at the end of the detection plate 32 is lifted. The end of the contact rod 33 is located at the bottom of the pressure-sensitive switch 43, causing the warning light 42 at the top of the pressure-sensitive switch 43 to light up. There are multiple detection plates 32 on the surface of the detection frame 3. The multiple equally spaced detection plates 32 enable the bubbles at different positions on the surface of the carton to touch the corresponding detection plates 32. Each detection plate 32 corresponds to a warning light 42. When the warning light 42 lights up, it indicates that there are bubbles or protrusions at the corresponding bottom carton, enabling the production personnel to quickly find the corresponding bubbles or foreign objects, thus facilitating the production personnel to check the corresponding equipment. At the same time, the foaming cartons are processed in a timely manner, reducing the generation of defective products, solving the problem of high error rate in manual quality inspection, and having a lower cost compared to electronic optical equipment.
