Non-contact induction snapping paper output device

technical field

The present invention relates to an occlusal paper output device for dental treatment, in particular to an inductive automatic occlusal paper output device, which belongs to the field of medical equipment.

the

Background technique

With the improvement of our country's medical level, the requirements for medical equipment have also increased accordingly. Bite papers are often used in dentistry. Most of the current occlusal papers require the doctor to touch the whole box of occlusal papers with both hands, and tear off a part from the whole box of occlusal papers to take. It is not only inconvenient to manually touch and take the occlusal paper, but also cause cross-infection of bacteria.

At present, there is no such product in the market. The emergence of this invention can solve the problem of cross-infection of bacteria in the use of occlusal paper, which is convenient for dentists to use. The doctor only needs to put his hand on the position of the sensor switch, trigger the sensor switch to turn on the device, and the bite paper will automatically protrude from the paper outlet of the device, and cut with the cutting mechanism according to the required length.

The working process of the contact induction occlusal paper output device of the technical solution of the present invention is as follows:

First, when the user puts his hand in the sensing area, the sensing switch starts, and the sensing switch turns on the motor through the control circuit; the motor starts, and the rotation of the motor becomes the rotation of two rollers through the transmission of the gear and the gear set. The biting paper is brought out from its roll by friction; when the length of the biting paper reaches the user's requirement, the hand leaves the sensing area, the motor stops rotating, and the biting paper stops stretching out; at this time, the operator pinches it with one hand with an operating tool such as tweezers Hold the occlusal paper, and cut the occlusal paper with the occlusal paper cutting mechanism. The motor can be used to set the rotational speed, and a pair of different gears can be selected according to the rotational ratio to effectively control the output rate of the interlocking paper.

Beneficial effect

The paper output device of the present invention automatically senses the interlocking paper, so that it is no longer necessary to touch the whole box of interlocking paper during operation. By triggering the sensor switch to open the device, the interlocking paper can automatically protrude from the paper outlet of the device, according to the needs The length is cut by a cutting mechanism, which is convenient and hygienic, and avoids cross-infection.

The inductive switch in this embodiment is a capacitive proximity switch, and its wiring principle is shown in Figure 5. It is characterized in that the user does not need to directly touch the switch with his hands, and at the same time, the switch is turned on and turned off. As shown in Figure 6, it shows the situation that the relative positions of the standard detection object 7, the detection object 8 and the electrodes are different; as shown in Figure 7, the capacitive proximity switch is also a position sensor with switch output, its The measuring head is usually a pole plate that constitutes a capacitor, and the other pole plate is the object itself. When the detection object 9 moves to the proximity switch, the dielectric constant between the detection object 9 and the sensing electrode 10 of the proximity switch changes. The state of the circuit connected to the measuring head also changes accordingly, so that the on and off of the switch can be controlled. The detection object of this proximity switch is not limited to metal conductors, but also insulating liquid or powder objects. When detecting objects with a lower dielectric constant ε, the multi-turn potentiometer (located at the rear of the switch) can be adjusted clockwise ) to increase the sensing sensitivity, generally adjust the potentiometer to make the capacitive proximity switch act at the position of 0.7-0.8Sn.
