When the timing reaches the time T0 determined by the design, the MCU sends an electric signal to the buzzer, the buzzer sends out a buzzing sound and stops heating the heating element at the same time, and the damage of the plastic piece to the hot damage is avoided.

Description

Laminator

Technical Field

The utility model relates to a paper is crossed and is moulded sealing device especially relates to a cross and mould machine.

Background

The laminator is used for covering the upper and lower surfaces of a paper or a photo with a plastic film respectively, and then performing hot pressing or cold pressing to form a laminator so as to facilitate storage. The cross machine during operation of moulding, wait to cross to mould the piece and cover by the plastic film back together and roll into integrative output through the gyro wheel of heating, at this moment, because the interior heating element residual heat of cross machine gyro wheel tastes, if the user does not in time shift out the article after the completion of moulding, then cross the end of moulding the piece and scald bad damage by the gyro wheel surface very easily.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model provides a safe plastic coating machine which can prevent the plastic coating from being burnt and damaged after the plastic coating is finished.

In order to achieve the above object, the present invention provides a laminator, including a roller control circuit, a temperature control circuit, further including: and the MCU controller is used for controlling a photoelectric detection loop of the output port of the laminator.

The temperature control loop comprises a temperature control protection loop or a temperature detection loop.

The photoelectric detection circuit comprises a light receiver.

The photo detection circuit includes a light emitter.

The light receiver is a photodiode, and the light emitter is a light emitting diode.

The MCU controller also controls a buzzer.

Because the utility model discloses cross and mould the machine, be equipped with the photoelectric detection return circuit that detects whether to move out of and report an emergency and ask for help or increased vigilance the bee calling organ of a suggestion of moulding the piece exit end in crossing, when crossing between the transmitter and the receiver of moulding the piece in photoelectric detection return circuit, the light of transmitter transmission is sheltered from by crossing the piece of moulding, the light of transmitter transmission can not be received to the receiver, the receiver can export an electric signal for the MCU controller, MCU begins the timing after receiving this electric signal. When the timing reaches the time T0 determined by the design, the MCU sends an electric signal to the buzzer, the buzzer sends out a buzzing sound and stops heating the heating element at the same time, and the damage of the plastic piece to the hot damage is avoided.

Detailed Description

The following describes in detail the preferred embodiments of the present invention with reference to the accompanying drawings.

As shown in the block schematic diagram of the laminator of fig. 1, the method comprises the following steps: the device comprises a power supply, an MCU controller, a buzzer 3, a photoelectric detection circuit 4, a temperature detection circuit 5, a temperature control protection circuit 6, a roller control circuit 7, a heating body 8 and a roller 9. The temperature control loop comprises a temperature control protection loop 6 or a temperature detection loop 5.

The photo-detection circuit 4 disposed at the output of the laminator as shown in fig. 2 and fig. 3 includes a photo-receiver, such as a photodiode, and may also include a light emitter, such as a light emitting diode, for receiving the emitted light by the photo-receiver. When the plastic part is output through the roller 9, if the light emitted by the emitter is shielded by the plastic part, the light receiver can not receive the light signal, the receiver can output an electric signal to the MCU, and the MCU starts timing after receiving the electric signal. When the timing reaches the preset time T0, the MCU sends an electric signal to the buzzer 3, the buzzer sends out a buzzing sound to indicate that the plastic coating is finished, and a user is reminded to move out of the plastic coating at the time; MCU is when sending the signal of telecommunication for bee calling organ, continue detecting the signal of optical receiver, as long as the signal shows that the receiver does not receive the light of light emitter, the time-recorder continues timing, when the timing reaches time T1 confirmed by design, MCU sends the signal of telecommunication for bee calling organ again, bee calling organ sends the beep sound again, show that after the moulding is accomplished one section time T1, the user does not remove the product of moulding, in order to avoid scalding the purpose of bad product of moulding and energy saving, the machine of moulding by mistake will stop heating, MCU can stop to supply power for heat-generating body 8 through temperature control protection return circuit 6, the machine of moulding by mistake simultaneously gets into standby mode. In the timing process, if the optical receiver receives the optical signal of the optical transmitter and indicates that the plastic product is removed, the optical receiver sends the signal to the MCU in real time, and the MCU immediately stops timing and restores the timer to the initial state.
