Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in figures 1 and 2, the roller clamping injury prevention mechanism for the signboard manufacturing equipment comprises a rack shell, wherein a lower roller and an upper roller which are parallel to each other are arranged in the rack shell, and a pressing gap is formed between the upper roller and the lower roller. And a material bearing plate is arranged outside the frame shell and at the same height with the pressing gap, and the plate is fed into the pressing gap from the material bearing plate.

Since, in a pinch, a person bends over, a person's body part or fingers are at the upper surface of the sheet material, usually appearing to be pinched at the upper part of the feeding site. Therefore, in the scheme, the diameter of the upper roller is set to be larger than that of the lower roller, the upper roller is more forward than the lower roller, a human body firstly contacts with the upper roller, the top of the upper roller is mostly scratched, and the upper roller is not easy to clamp; and visually, the human is more attentive.

In the scheme, a rotating shaft A1 of the lower roller and a rotating shaft B2 of the upper roller are respectively installed in a rack shell through a bearing A and a bearing B, the lower roller is provided with a roller shell A3, and the upper roller is provided with a roller shell B4.

In order to prevent the fingers of a person from being clamped, the roller shell A3 is designed in such a way that: the roller shell comprises a plurality of arc-shaped petals 301, the arc-shaped petals 301 are arranged along the same circular track, the arc-shaped petals 301 are combined to form a roller shell A3, and a steel sheet layer 6 playing a pressing role is wrapped outside the roller shell A3. Arc flap 301 passes through cylinder 5 and pivot A1 fixed connection, and the bottom of cylinder 5 is fixed on pivot A1 and the telescopic shaft is fixed with arc flap 301, and pivot A1 is the quill shaft, and pivot A1 is linked together with cylinder 5, and the one end of pivot A1 is provided with electronic pneumatic valve, and the other end of pivot A1 is linked together through rotary joint and trachea, and the trachea links to each other with the air pump. The feeding part of the upper roller is also provided with a laser sensor, and the laser sensor is connected with a relay switch of the electric air valve.

When the whole pressing mechanism needs to be formed, the electric air valve is closed, the air pump charges air into the rotating shaft A1, the flushed air enters the air cylinder 5 to eject the telescopic shaft, so that the arc-shaped petals 301 are ejected, the ejected arc-shaped petals 301 form a complete roller shell A3, the roller shell A3 props up the steel sheet layer 6, and the surfaces of the steel sheet layer 6 and the roller shell B4 form a pressing surface.

In the working process, when people do not pay attention to the pressing feeding position, the hand is sensed by the laser sensor, the laser sensor generates a pulse signal and transmits the pulse signal to the relay switch of the electric air valve, the relay switch controls the electric air valve to be opened, air leakage is realized, the pressing force disappears, the fingers of people cannot be injured, and the fingers are slightly extruded at most; and simultaneously arc petal body 301 is under the effect of gravity, and automatic downward movement makes original suppression clearance grow to can't produce the power of pressing the wound to the finger.

In order that the arc-shaped petal body 301 can timely move back and forth towards the rotating shaft A1 as a center, two ends of the roller shell A3 are installed in a matched mode with the rotating shaft A1 through a bearing A, two ends of the roller shell A3 are provided with belt grooves, a belt is sleeved in the belt grooves, the contact position of the belt and the belt grooves is located above the roller shell A3 and close to the pressing position of the roller shell B4, and the belt is connected with the driving motor A. When the electric air valve is deflated, the arc-shaped flap 301 can be pulled downwards under the action of the belt, so that the downward pressing force is reduced.

In this embodiment, the disk frame for primarily supporting the steel sheet layer 6 is disposed at two ends of the steel sheet layer, and the disk frame is welded on the rotating shaft a.

In this embodiment, the roller shell B4 is designed to be cylindrical by adopting a conventional structure, two ends of the roller shell B4 are installed in a matching manner through a bearing B and a rotating shaft B, two ends of the roller shell B4 are provided with belt grooves, a belt is sleeved in the belt grooves, and the belt is connected with a driving motor B.

Furthermore, because the roller shell A3 of the lower roller is composed of the arc-shaped petals 301, gaps are formed between the adjacent arc-shaped petals 301, and the gaps are not pressed during pressing, two pairs of upper and lower rollers are arranged in the frame shell, and when the gap positions of the first pair of upper and lower rollers are not pressed, the rollers are pressed when being moved to the second pair of upper and lower rollers, so that all positions of the plate are pressed.
