Disclosure of Invention

The invention aims to provide a cutting device to solve the problem that in the cutting process of leather, the leather is easy to attach to a cutting tool to affect the cutting effect.

In order to achieve the purpose, the basic scheme of the invention is as follows: a cutting device comprises a base, wherein a pillar and a cross beam which are connected in sequence are arranged on the base, an air cylinder with a downward piston rod is arranged on the cross beam, an inwards concave annular tool bit is arranged at the free end of the piston rod, a workbench is arranged at a position, below the annular tool bit, of the base, the air cylinder is hinged to the cross beam, a slide rail is arranged on the pillar, the lower portion of the slide rail is vertical, the upper portion of the slide rail inclines to one side, the piston rod is provided with a cavity structure, an air suction hole is formed in the annular tool bit and is communicated with the cavity structure, a sleeve is arranged between the annular tool bit and the air cylinder and is in sealed connection with the air cylinder, a push plate fixedly connected with the piston rod is arranged in the middle of the piston rod, an air outlet hole communicated with the cavity structure is formed in the, the cross bar is connected with the slide rail in a sliding manner.

The working principle of the basic scheme is as follows: before cutting by the device, leather is placed on the workbench, the air cylinder is started, the piston rod moves towards the workbench, and the piston rod moves to drive the push plate and the annular cutter head to move downwards; the push plate moves downwards, a negative pressure cavity is formed between the upper surface of the push plate and the lower end surface of the air cylinder, the push plate is driven by the piston rod to continuously move downwards, air enters the negative pressure cavity through the air suction hole, the cavity structure and the air outlet hole, the lower end surface of the air suction hole is in a negative pressure state, the annular cutter head is in contact with the leather to adsorb the leather, the annular cutter head cuts the leather, and the cut shape of the leather is the same as that of the blade; after cutting, the piston rod is controlled to contract upwards, and the piston rod moves upwards to drive the push plate to move upwards; the cross bar moves upwards along the slide rail on the strut; after the cross rod moves to the upper part of the sliding rail, the upper part of the sliding rail inclines to one side, so that the air cylinder and the piston rod incline to one side, meanwhile, along with the continuous contraction of the piston rod, the push plate extrudes air in the negative pressure cavity, and meanwhile, the air blows off the leather from the annular blade through the air outlet hole, the cavity structure and the air suction hole. After the piston rod stops contracting, the piston rod begins to extend out again, and the air cylinder is in a vertical state when the cross rod moves to the lower part of the sliding rail.

The beneficial effect of this basic scheme lies in:

(1) set up the cavity structure on the piston rod and with venthole and the suction opening that the cavity structure is linked together, set the push pedal to slide and sealing connection with the sleeve, be convenient for when the push pedal moves down along with the piston rod, stretch out through the piston rod and just can cut the cladding, simultaneously, adsorb the cladding after will cutting through the tool bit, realized multiple effect when the cutting.

(2) The slide rail is arranged on the pillar, the lower portion of the slide rail is set to be in a vertical state, the upper portion of the slide rail inclines towards one side, the cross rod is arranged between the slide rail and the piston rod, the cross rod can be driven to slide along the guide rail by controlling the piston rod to move upwards, the air cylinder and the piston rod can incline when the cross rod moves upwards along the slide rail, and meanwhile, the leather adsorbed by the tool bit is transferred to the outside of the workbench through the inclined piston rod along with the upward movement of the piston rod. The device can realize the lifting, transferring and material removing of the leather when the piston rod is contracted, does not need to manually transfer the cut leather, saves a large amount of manpower labor, improves the cutting efficiency and saves the labor cost.

Compared with the prior art, the device can realize the cutting and the transfer of the leather through the extension of the piston rod, the leather after the cutting is prevented from being adsorbed in the annular cutter head, the cutting is influenced, the device is simple to operate, and the cutting efficiency is high.

Further, annular tool bit rotates with the piston rod to be connected, be equipped with the motor that the output shaft is to the downside on the horizontal pole, be connected with the belt between the output shaft of motor and the annular tool bit, when not good to the cladding cutting effect, can drive annular tool bit through opening the motor and rotate, annular tool bit rotation enables the cutting effect more abundant, has improved cutting efficiency.

Further, the annular groove is formed in the outer side of the annular cutter head, the belt is prevented from being separated from the annular cutter head through the annular groove, and the transmission effect of the motor is guaranteed.

Furthermore, the aperture of the air outlet is larger than that of the air suction hole, so that when the piston rod extends out, a negative pressure cavity is formed between the push plate and the lower end face of the air cylinder, air enters between the push plate and the lower end face of the air cylinder from the air suction hole, the aperture of the air outlet is larger than that of the air suction hole, and the flow of the air passing through the air outlet is larger than that of the air sucked by the air suction hole, so that the cut leather can be better adsorbed by the air suction hole due to larger adsorption force; when the air suction holes are used for exhausting air, good air flow can be formed at the air suction holes, and cut leather is blown away from the annular cutter head.

Further, be equipped with the pulley that can slide in the slide rail between horizontal pole and the slide rail, through setting up the pulley, can reduce the friction between horizontal pole and the slide rail, make the horizontal pole have better slip effect, prolonged the life of horizontal pole simultaneously.

Further, be equipped with between cylinder and the crossbeam and be used for driving the cylinder and make it be the torsional spring of vertical state, after the cylinder takes place to incline, enable the cylinder and resume vertical state fast under the effect of torsional spring and piston rod.
