Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

The first embodiment is as follows: an intelligent protection paper cutter is shown in fig. 1 and fig. 3 and comprises a frame 1, a paper cushion plate 11 arranged on the frame 1, a cutter seat 2 connected to the frame 1 in a sliding manner, a paper cutter 21 connected to the cutter seat 2, a driving mechanism 3 for driving the paper cutter 21 to slide along the length perpendicular to a paper feeding plate, and a protection plate 22 connected to the paper feeding side of the paper cutter 21. When the paper cutter works, a worker pushes paper to be cut along the length direction of the paper cushion plate 11, then the driving mechanism 3 is started, and the paper cutter 21 cuts the paper in a reciprocating manner under the driving of the cutter holder 2, so that the paper cutting function is realized.

The machine frame 1 is provided with a driving track 12 along the moving direction perpendicular to the paper, the driving mechanism 3 comprises a motor 31 connected to the machine frame 1, and a screw rod 32 connected to an output shaft of the motor 31 and located in the driving track 12, wherein the tool apron 2 is sleeved outside the screw rod 32 and in threaded fit with the screw rod 32, the screw rod 32 is a bidirectional screw rod, and the tool apron 2 reciprocates along the screw rod 32.

Still be equipped with the spacing track 13 that is on a parallel with drive track 12 on frame 1, spacing track 13 is located drive track 12 one side, blade holder 2 be equipped with spacing track 13 complex spacing groove to when making lead screw 32 rotate, blade holder 2 can be at spacing of spacing track 13 down, along spacing track 13's length direction motion, and then drive paper cutter 21 and cut the paper along drive track 12's direction.

Because the paper has a certain tension, the paper may have up and down fluctuation when cutting, which results in that the cutting of the paper is not smooth enough, and therefore, a paper pressing mechanism 27 is arranged on one side of the working direction of the paper cutter 21. The paper pressing mechanism 27 includes an elastic telescopic rod connected to the cutter base 2 and abutted against the paper cutter 21, and an abutting wheel 26 rotatably connected to the bottom of the elastic telescopic rod and abutted against the paper, and the abutting wheel 26 is driven by the paper to rotate, so that the paper cannot be easily damaged, and the integrity of the paper is ensured.

Elastic expansion pole is including connecting in the flexible outer pole 23 of blade holder 2, and flexible outer pole 23 is for being the tubulose, and sliding connection has flexible interior pole 24 in flexible outer pole 23, is equipped with between flexible interior pole 24 and the blade holder 2 and supports tight spring 25, supports tight spring 25 and is located flexible outer pole 23, and one end is connected in the flexible interior pole 24 other end and is connected in blade holder 2. Through the design of the abutting spring 25, the abutting wheel 26 can be always abutted against the paper, and can also be lifted by compressing the spring under the pressure of the paper, so that the paper is not damaged.

Example two: an intelligent protection trimmer is shown in fig. 1 and 4, and is different from the first embodiment in that: the paper cutting machine further comprises a detector 4 connected to the frame 1 and located on the paper feeding side of the paper cutter 21, and a control circuit 5 coupled to the detector 4 and controlling the motor 31 to be turned on or off according to a detection signal of the detector 4. The control circuit 5 may be understood as a normally closed contact switch coupled between the power source and the motor 31, electrically connected to the detector 4, and controlled by the detector 4, and when receiving the detection signal from the detector 4, the contact switch is opened to turn off the motor 31.

The detector 4 comprises a plurality of infrared transmitters arranged on one side of the rack 1 and infrared receivers arranged on the other side of the rack 1 and corresponding to the infrared transmitters one to one. When motor 31 during operation, detector 4 is in operating condition all the time, and when staff's arm or other positions were too close to paper cutter 21, can shelter from infrared emitter, the infrared receiver who does not receive infrared signal this moment can react rapidly, and control motor 31 outage makes paper cutter 21 scram.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
