Description

Technical Field

[0001] This application relates to the field of decorative paper technology, specifically to a testing device for architectural decorative paper. Background Technology

[0002] In the production process of building decoration materials, the quality of decorative paper directly affects the aesthetics and service life of the final product. Traditional manual testing methods are not only inefficient, but also easily affected by subjective judgment, leading to inconsistent and unreliable test results. Therefore, it is particularly important to develop an automated building decoration paper testing device.

[0003] For example, a wrinkle detection device for decorative paper disclosed in Chinese Patent Publication No. (CN212872227U) belongs to the field of decorative paper preparation technology. The wrinkle detection device for decorative paper includes a lower frame, with first guide rails fixedly installed on both the left and right sides of the upper surface of the lower frame. A sliding frame is slidably connected to the outer surface of the first guide rails. A placement plate is fixedly installed on the upper surface of the sliding frame. Fixed posts are fixedly installed on the outer side of the placement plate. Support frames are fixedly installed on both the front and rear sides of the upper surface of the lower frame. An upper frame is fixedly installed above the support frames. A second guide rail is fixedly installed on one side of the inner side of the upper frame. A sliding rod is slidably connected to the outer surface of the second guide rail. A detection post is fixedly installed on the lower surface of the sliding rod. A detection head is fixedly installed at the lower end of the detection post. Through the setting of the fixed post and the placement plate, the decorative paper can be neatly placed on the placement plate. Through the setting of the third conveyor belt and the sliding rod, the detection head can be moved by the rotation of the third conveyor belt.

[0004] However, as mentioned in the patent above, there is still a problem with the poor detection and removal effect on decorative paper. For example, the patent above uses a movable detection head to detect quality problems such as wrinkles after the decorative paper is laid flat. However, this method can only detect the problem but cannot cut the problematic area after detection to facilitate the mass production of decorative paper. Utility Model Content

The longitudinal linear module is fixed to the left side of the lower surface of the support frame, the fixed frame is fixed to the lower surface of the longitudinal linear module, and the transverse adjustment frame is fixed to the lower surface of the fixed frame. The two ends of the adjusting screw are rotatably connected to the inner walls of the left and right sides of the transverse adjustment frame through bearings, respectively. The servo motor is fixed to the right side of the transverse adjustment frame, and the outer side of the servo motor output shaft is fixedly connected to the adjusting screw. The moving block is threadedly connected to the outer side of the adjusting screw.

[0017] By adopting this technical solution, the cutting action becomes fast and accurate, improving cutting efficiency and the quality of decorative paper.

[0018] Furthermore, the upper and lower inner walls of the horizontal adjustment frame are fixed with slide rails, and the upper and lower sides of the moving block are provided with slide grooves, and the moving block is slidably connected to the outside of the two slide rails through the two slide grooves respectively.

[0019] By adopting this technical solution, the cutting parts can be quickly and accurately positioned on the decorative paper, ensuring the efficiency and precision of the cutting process.

[0020] Furthermore, the shape of the horizontal adjustment frame is a cuboid with a hollow interior and missing front and rear sides, and the cross-sectional shape of the moving block is H-shaped.

The controller is electrically connected to the testing probes and is responsible for receiving, processing, and analyzing the signals from the testing probes to determine whether the decorative paper meets the quality standards.

[0023] 2. The inspection device for architectural decorative paper includes a cutting mechanism. First, the decorative paper is conveyed by the main conveyor. The inspection mechanism then checks the surface quality of the decorative paper. When contamination is detected, the cutting mechanism is activated. During operation, the positioning probe and controller work together to drive the cutter longitudinally via a linear module. A servo motor drives an adjusting screw, causing the moving block to move along the adjusting screw. This achieves precise lateral positioning of the defective part of the decorative paper. When a defect is detected, the cutter removes the defective part, ensuring the efficiency and accuracy of the cutting process. Attached Figure Description

When the building decorative paper passes through the conveyor body 1, the detection probes 24 perform visual inspection on the paper surface to identify defects or quality problems on the surface of the decorative paper. The controller is electrically connected to the detection probes 24. The controller is responsible for receiving the signals from the detection probes and processing and analyzing them to determine whether the decorative paper meets the quality standards.

[0034] (2) When cutting off the soiled parts of the decorative paper, the decorative paper is first conveyed by the main body 1 of the conveyor.

The moving block 36 is equipped with a cutting part 37. When a defect is detected, the positioning probe 375 sends a signal to control the output shaft of the cylinder 371 to move, thereby pushing the cutter 373 to contact and cut off the defective part. The shape of the lateral adjustment frame 33 and the sliding groove design of the moving block 36 enable the cutting part 37 to be positioned quickly and accurately on the decorative paper, ensuring the efficiency and precision of the cutting process.
