Detailed Description

The label-print quality inspection apparatus of the present utility model will be described in more detail below with reference to the drawings, in which preferred embodiments of the present utility model are shown, it being understood that one skilled in the art may modify the utility model described herein while still achieving the beneficial effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.

The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the utility model will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1, an embodiment of the present utility model provides a label print quality detection apparatus, which includes a conveying table 1, a detection mechanism 2, and a positioning assembly 3.

The conveying table 1 is sequentially provided with the positioning assembly 3 and the detection mechanism 2 from outside to inside along the conveying direction, so that a product to be detected sequentially passes through the positioning assembly 3 and the detection mechanism 2, the product to be detected is gathered through the positioning assembly 3, the label of the product to be detected is positioned under the detection mechanism 2, the detection rate is improved, and the cost of people is reduced.

In this embodiment, a specific positioning component 3 is provided to improve the gathering effect of the product to be tested.

Specifically, the positioning assembly 3 includes two deviation correcting plates 31 and a sliding plate 32.

The two deviation correcting plates 31 are symmetrically rotated on two sides of the conveying table 1 and used for limiting and gathering products to be tested.

The sliding plate 32 is movably installed between the two deviation correcting plates 31.

Specifically, when the sliding plate 32 is extruded by the conveying power of the product to be detected and slides along the direction close to the detection mechanism 2, the two deviation correcting plates 31 are pulled to be close along the axial lead of the conveying table 1, and the sliding plate 32 moves upwards along the vertical direction, so that a gap for the movement of the product to be detected is formed between the bottom wall of the sliding plate 32 and the conveying table 1.

As shown in fig. 2 and 3, the device utilizes the power of the product to be tested (as shown by the dashed rectangle) to be conveyed by the conveying table 1 to contact with the sliding plate 32, and then the sliding plate 32 slides along the conveying direction of the conveying table 1 by the power of the product to be tested, so as to drive the deviation correcting plate 31 to deflect. And because the sliding plate 32 can also slide along the vertical direction when sliding along the conveying direction of the conveying table 1, a gap is formed between the sliding plate 32 and the conveying table 1 and is used for the product to be detected to slide out, when the product to be detected slides out, the product to be detected can be acted by the inclined surfaces of the deviation correcting plates 31 and gradually slide between the two deviation correcting plates 31 (as shown in fig. 3), the purpose that the product to be detected is limited and gathered can be achieved, the surface label of the product to be detected is positioned under the detecting mechanism 2, the detecting speed is improved, and meanwhile, the labor cost is effectively saved.

It should be noted that, when the product to be measured passes through the sliding plate 32, the ends of the two deviation correcting plates 31 are abutted against the product to be measured, that is, the dimension of the product to be measured should be greater than the distance between the end of the deviation correcting plate 31 and the sliding plate 32 along the conveying direction of the conveying table 1, so that when the product to be measured contacts with the deviation correcting plate 31, the tail end of the product to be measured contacts with the sliding plate 32, and the deviation correcting plate 31 is ensured to gather the product to be measured.

In other embodiments, to avoid damage to the product under test caused by extrusion between the end of the correction plate 31 and the product under test. One end of the deviation correcting plate 31, which is abutted against the product to be detected, is provided with a roller 311 to reduce the friction force of the product to be detected.

In this embodiment, the deviation correcting plate 31 is further limited, so that the deviation correcting plate 31 improves the collecting effect of the product to be tested. The middle part of the deviation correcting plate 31 rotates on the conveying table 1 through a rotating shaft, and one end of the deviation correcting plate extends to the conveying table 1. In addition, the torsion spring is sleeved on the outer wall of the rotating shaft, so that when the product to be tested is separated from the sliding plate 32, the product to be tested can be reset independently, and the next product to be tested is subjected to closing limiting.

With continued reference to fig. 1, in this embodiment, a limiting slot 312 is further provided and the shape thereof is further defined, so that when the sliding plate 32 slides along the conveying direction of the conveying table 1, the two deviation correcting plates 31 can be pulled to swing and can move along the vertical direction.

A limiting groove 312 is formed on one side of each of the two deviation correcting plates 31, which is close to each other; the two sides of the sliding plate 32 are rotatably provided with limiting posts 321 matched with the limiting grooves 312, and the sliding plate 32 is integrally connected with the deviation correcting plate 31, so that the sliding plate 32 can be pushed to swing when subjected to external force, such as when a product to be tested is used for conveying power, and preparation work is performed for subsequent deviation correction.

Further, the limit groove 312 is provided so as to be inclined so that the slide plate 32 moves upward in the vertical direction to form the gap with the conveying table 1 when slid in the direction approaching the detection mechanism 2. That is, when the sliding plate 32 slides, it will move along the predetermined track, and because the limiting slot 312 is inclined, the sliding plate 32 can also move along the vertical direction while sliding, so as to ensure that a corresponding gap can be formed between the sliding plate 32 and the conveying table 1, and the product to be tested can slide out.

In other embodiments, the cleaning roller 322 is rotatably installed at the bottom of the sliding plate 32 to clean impurities on the surface of the product to be tested, so as to prevent the label from being polluted by dust or impurities, and cause inaccurate subsequent detection. In addition, the cleaning roller 322 can also be used as a rolling member to reduce the friction resistance when the product to be tested moves.

Specifically, when the gap is greater than or equal to the thickness of the product to be measured, the product to be measured abuts against the cleaning roller 322, and under the conveying power of the conveying table 1, the product to be measured slides relatively to the cleaning roller 322, and the cleaning roller 322 is pulled to rotate, that is, the product to be measured can be cleaned in the rotation process of the cleaning roller 322.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
