Description

Technical Field

[0001] This utility model relates to the field of ceramic tile processing and testing devices, and more specifically, to a ceramic tile pre-inkjet surface testing device. Background Technology

[0002] One step in tile production is to use inkjet printing equipment to spray the desired pattern onto the surface. However, some tiles may be uneven during production, especially the raised parts. These uneven parts can cause damage to the printhead when passing through the inkjet printing equipment, affecting subsequent production and increasing equipment costs. Therefore, it is necessary to inspect and warn the tile surface before it enters the inkjet printing equipment to prevent tiles with obvious raised defects from entering the equipment and causing damage. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a ceramic tile surface detection device before inkjet printing, which can detect defective ceramic tiles with raised height reaching the warning area, and warn the staff to deal with the ceramic tiles in time to prevent the ceramic tiles from damaging the print head of the inkjet equipment.

The shapes of the first and second clamping grooves are adapted to the shape of the sleeves, and the first and second clamping grooves are provided with pin holes. The sleeves at both ends of the suspension rope are respectively inserted into the first and second clamping grooves and fixedly connected by pins.

[0008] In a preferred embodiment of this invention, the windshield includes two channel steels with opposing slots, and windshield plates are bolted to the side walls of the channel steels to form a windshield with openings at the top and bottom.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 4 As shown in the figure, a specific embodiment of the present invention discloses a ceramic tile inkjet front surface inspection device, including a frame 100, a baffle 200, and a hanging assembly 300; two frames are symmetrically arranged on both sides of the conveyor belt, the hanging assembly 300 is installed on the top of the frame 100, and the baffle 200 is suspended between the two hanging assemblies 300, so that the baffle spans across the top of the conveyor belt; a wind shield 400 is provided on the outer side of the baffle 200, and at least two distance sensors 500 are installed on the wind shield 400, with the probes of the distance sensors 500 facing the wall of the baffle 200 along the conveying direction of the conveyor belt.

[0027] The aforementioned surface inspection device for inkjet-printed ceramic tiles uses a suspended design to keep the baffle in a suspended state. When a defective tile with a protrusion reaching the warning level passes below, the baffle will shift and shake, triggering a distance sensor and thus an externally connected alarm. This alerts staff to promptly handle the tile and prevent it from damaging the printhead of the inkjet equipment. The wind shield design protects the baffle from external wind, preventing it from shaking and avoiding false triggering.

[0028] Furthermore, such as Figure 3 , Figure 5 As shown, the hanging assembly 300 includes a hanger 310, a lifting ring 320, and a lifting rope 330. The hanger 310 is fixed to the top side wall of the upright 100 by bolts. The hanger extends outward away from the upright. The outer end of the hanger 310 is connected to the lifting ring 320 by the lifting rope 330. Support bolts 210 are installed at both ends of the baffle 200. The support bolts 210 are movably inserted through the lifting ring 320. The whole assembly adopts an assembled structure, which facilitates the processing and production of each structural component and is also easy to assemble and use. The two ends of the baffle are engaged with the lifting ring by the support bolts, which provides a basis for movable swinging and improves the trigger sensitivity.

[0029] Furthermore, such as Figure 6 , Figure 7 As shown, both ends of the suspension rope 330 are fixedly covered with sleeves 331, and the sleeves 331 are provided with first threaded holes; the bottom surface of the outer extension end of the bracket 310 is provided with a first clamping groove 311, and the top of the lifting ring 320 is provided with a second clamping groove 321. The shapes of the first and second clamping grooves are adapted to the shape of the sleeves, and the first and second clamping grooves are provided with pin holes. The sleeves 331 at both ends of the suspension rope 100 are respectively inserted into the first clamping groove 311 and the second clamping groove 321 and are fixedly connected by pins; an assembly structure is adopted, and a centrally symmetrical structural combination is adopted to make the hanging center level, so that the baffle is hung level and to prevent missed inspection parts; furthermore, the sleeves are fitted onto the ends of the suspension rope and can be fixedly connected by glue or hot melt glue. The sleeves are better connected and matched with the bracket and the lifting ring to achieve uniformity of assembly and consistent hanging length.

[0030] Furthermore, such as Figure 8As shown, the wind deflector 400 includes two channel steels 410 with facing slots, and wind deflector plates 420 bolted to the side walls of the channel steels 410, forming a wind deflector with openings at the top and bottom. It adopts an assembled structure, which facilitates the processing and production of each structural component and simplifies assembly. A notch 411 is provided at the top of the wall near the upright of the channel steel 410, and the shape of the notch 411 matches the shape of the hanger 310. The channel steel is fixedly installed on the top of the upright by bolts, and the hanger is placed at the notch, so that the hanging assembly is located inside the wind deflector. The bottom of the baffle is lower than the bottom surface of the wind deflector plate. The hanging assembly and the baffle are effectively protected, which effectively prevents the external airflow from causing the hanging rope and the baffle to sway, reducing the occurrence of false alarms.

[0031] Furthermore, the bottom of both ends of the wind deflector is provided with through holes, and a distance sensor is installed at each through hole; there are 4 distance sensors. When any distance sensor is triggered, it will trigger an externally connected alarm. Staff need to check and verify to ensure that the tiles have no raised defects; to prevent the failure of some distance sensors from affecting the overall monitoring accuracy.

[0032] Furthermore, the bottom of the baffle 200 is fixedly covered with a soft rubber strip 220. The bottom of the soft rubber strip has an outward convex arc shape to prevent scratches on the tile surface and avoid affecting the subsequent repair and recycling of the tile.

[0033] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
