Description

Automatic test paper feeder

technical field

The utility model belongs to the technical field of medical equipment, in particular to an automatic paper feeding machine for test paper.

Background technique

Domestically produced test strips for urine testing are usually packed in paper tubes from production to delivery to the hospital. The test strips are arranged in disorder in the paper tube and cannot be used for medical testing immediately. It is often necessary to separate the test strips and use them. It is delivered face up into the drop detection device. The existing test paper separation mechanism uses grooved rollers to identify the front and back of the test paper, judges the direction of the test paper through sensors and flips it accordingly so that the front side falls on the conveyor belt. However, it often happens that the test strip does not fall into the groove as expected but is stuck between the roller and other mechanisms, which makes subsequent work such as dripping and analysis impossible. In addition, there is no paper dust collection device inside the existing equipment. After long-term use, a large amount of debris will accumulate in the equipment, which will not only cause pollution, but also affect the operation of the equipment.

Contents of the invention

The technical problem to be solved by the utility model is to provide an automatic test paper feeder capable of separating messy test paper strips, judging the front and back sides, returning the face-down test paper strips, and correcting the output position of the test paper.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:

An automatic test paper feeding machine, comprising a motor arranged on a bracket and a test strip separation mechanism driven by the motor, characterized in that it also includes a toothed belt arranged close to the test paper groove, two toothed belts, The distance between the toothed belts is five to six centimeters. In order to prevent the test strip from being stuck in the test paper slot, there is a horizontal baffle between the two toothed belts. The horizontal baffle is seamlessly connected with the test paper slot. The height of the convex teeth on the outer surface of the toothed belt is The thickness of the test strip, the toothed belt is obliquely connected on the driving shaft and the driven shaft; there is a steering gear between the toothed belts of the test strip separation mechanism, and the dial of the steering gear can be wound on the plane of the toothed belt parallel to the driving shaft. The rotating shaft of the shaft rotates back and forth; the upper end of the test strip separation mechanism is connected with a limit mechanism, which is composed of three inclined baffles, and there are gaps between the inclined baffles to allow the test paper to pass through.

In order to make the driving shaft obtain stable power, the driving shaft and the motor are driven by belts.

In order to correct the lateral position of the test strip after passing through the toothed belt, the side baffles of the three sliding plates of the limit mechanism are gradually narrowed downward.

Preferably, in the above solution, the angle between the sliding plate of the limit mechanism and the horizontal plane is less than 45 degrees.

Preferably, in the above solution, the upper side of the first slide baffle of the limiting mechanism is as wide as the two toothed belts.

Compared with the prior art, the utility model has the following advantages:

1. The test paper separation mechanism ensures that one test paper strip is sent up each time, so that the test paper strip will not be stuck between the test paper notch and the toothed belt.

2. The image recognition mechanism judges the front and back of the test strips, and uses the dial to dial down the test strips with the front facing down or with an inappropriate time interval, so that they fall back into the test strip slot, which optimizes the previous use of a rotating drum to perform flip tests. The paper strip has the defect that the test strip is stuck in the contact gap.

3. The limit mechanism corrects the horizontal position of the test strip to ensure that the test strip is accurately transported to the next link.

detailed description

Below in conjunction with Fig. 1, 2, further describe the utility model by example.

The test paper automatic paper feeder in the present embodiment includes the motor 5 and the belt for transmission that are located on the support 1, and of course the transmission can also be in other ways. The test paper automatic paper feeder also includes a test paper slot 7, a test strip separation mechanism 2, a limit mechanism 4, and a steering gear 3. The test paper tank is obliquely fixed on the support 1, with the test paper notch facing downwards and in contact with the horizontal baffle to ensure that the test paper in the test paper tank can automatically slide onto the toothed belt and not be caught in the gap between the test paper tank and the toothed belt. The test strip separation mechanism 2 is composed of a toothed belt, a driving shaft 2-1 and a driven shaft 2-2. The number of convex teeth on the outer surface of the toothed belt is related to the motor speed, so as to ensure that the test strips can be delivered at a fixed time interval; The height of the protruding teeth of the shaped belt is two-thirds of the width of the test strip to the entire width of the test strip. The angle between the sides of the convex teeth and the toothed belt does not exceed 45 degrees, and the inclination angle of the toothed belt does not exceed 45 degrees to ensure that the test strips It can be taken away by the protruding teeth and will be turned directly onto the toothed belt due to gravity; the toothed belt is fixed on two rotating shafts, and the two rotating shafts are fixed on the bearing seat fixed on the bracket 1; the limit mechanism 4 consists of three slide plates Composition, the side of the skateboard has a gradually shrinking baffle, the distance between the baffles at the joint of the skateboard is the same, the distance between the first skateboard and the outer side of the toothed belt is the same, the inclination angle of the skateboard does not exceed 45 degrees, the skateboard is fixed on the bracket 1, and the third skateboard The lower end is connected to the entrance of the detection instrument, and the connecting distance between the baffles is the width of the test paper; the steering gear 3 is fixed on the bracket 1, and is controlled by the image recognition mechanism 6. When the camera at the upper left of the toothed belt captures the image of the test strip facing or when the output time of the test strip is inappropriate, the driving bar of the steering gear 3 will keep protruding from the outer surface of the toothed belt, separate the test strip from the toothed belt, and let it return to the test paper groove. When it is detected that the test strip is facing up and outside the output time interval, the image recognition mechanism 6 triggers the dial of the steering gear 3 to turn it under the outer surface of the toothed belt to allow the test strip to pass.

Of course, the above is a detailed description of the preferred specific implementation of the utility model in conjunction with the accompanying drawings, and does not limit the scope of implementation of the utility model. All equivalent changes made according to the principle, structure and structure of the utility model should be included in Within the protection scope of the present utility model.
