Summary of the invention
The present invention will solve the problems of the technologies described above, thus provides a kind of sanction cutting device of horizontal type fabric cutting machine, and cutting knife and cloth can be avoided to bond, and improves cutting efficiency.
The technical scheme that the present invention solves the problem is as follows: a kind of cutting device of horizontal type fabric cutting machine, comprise support, motor, drive and cylinder blade, described motor is arranged on support, described drive rotates and is arranged on support, described motor drives drive to rotate, described drive drives cylinder blade to rotate, and described cylinder blade is arranged on swing mechanism, and described swing mechanism driver plate blade is presented periodical and swung.
The present invention, by being arranged on swing mechanism by cylinder blade, makes it keep relative motion state with cloth all the time cutting in process, and constantly changes cylinder blade and the contact surface of cloth, makes cylinder blade accelerate heat radiation, lower the temperature, avoids boning with cloth; When cylinder blade moves in the horizontal direction simultaneously, move presenting periodical again, cylinder blade is moved along sinusoidal path, the cutting of existing horizontal direction when cutting, there is again the cutting of above-below direction, substantially increase cutting efficiency and cutting effect, even if the cylinder blade of passivation still has good cutting effect.
As preferably, described swing mechanism comprises swing span, and described swing span is provided with three hinged ends in angular distribution, and three hinged ends distributions are hinged on support, cylinder blade and drive.
As preferably, described swing span comprises swing arm and support arm, and one end of described swing arm is hinged on support, and the other end is hinged with cylinder blade; Described support arm is arranged between drive and swing arm, and one end of described support arm is hinged on drive, and the other end is connected in swing arm, and when described drive rotates, described support arm drives swing arm to swing, and makes cylinder blade present periodical and swings.
As preferably, the side of described drive is provided with rotational pin, and described rotational pin is positioned at the position away from drive pivot center, and one end and the rotational pin of described support arm are hinged.
As preferably, driven between described motor and drive by the first driving-chain, described drive and cylinder blade are driven by the second driving-chain, and described second drive chain is provided with strainer.
As preferably, described strainer comprises regulating wheel, nutted rod, backstand and elastic component, described backstand is fixed on support, one end of described nutted rod is slidably connected on backstand, the other end and regulating wheel hinged, described elastic component is arranged between nutted rod and backstand, makes regulating wheel carry out tensioning by the elastic force of elastic component to the second drive chain.
As preferably, described support arm is extensible arm, comprises the first support arm and the second support arm, and described first support arm is socketed in the trepanning of the second support arm, is provided with spring in described trepanning, and described first support arm is connected with the second support arm elasticity.
Because cylinder blade easily produces resonance in periodic wobble process, produce larger noise, therefore extensible arm is set and the first support arm is connected with the second support arm elasticity, support arm is made to have buffer time in the transmittance process of power, and absorb vibration by spring, make cutting device peace and quiet, work reposefully.
As preferably, described second support arm is provided with stop screw, one end of described stop screw wears in trepanning, described first support arm is provided with stopper slot, one end that described stop screw is positioned at trepanning wears stopper slot, and described first support arm and the second support arm limit the collapsing length of support arm by the position-limiting action of stop screw and stopper slot.
The present invention has following beneficial effect: the present invention can make cylinder blade radiating block, good cooling effect, can avoid boning with cloth; The simultaneously cutting of existing horizontal direction when cutting, has again the cutting of above-below direction, substantially increases cutting efficiency and cutting effect, even if the cylinder blade of passivation still has good cutting effect.
Detailed description of the invention
This detailed description of the invention is only explanation of the invention, is not to limit the present invention.Any change that those skilled in the art are done after having read description of the present invention, as long as in the protection domain of claims, all will be subject to the protection of Patent Law.
Embodiment: as shown in Figure 1, a kind of horizontal type fabric cutting machine, the protective cover 10 comprising guide rail 1, support 2, motor 3, drive 4, cylinder blade 5 and be arranged on cylinder blade 5.Support 2 moves horizontally along guide rail 1, and support 2 is provided with the guide wheel 9 slided on guide rail 1, and guide wheel 9, in distributing up and down, is conflicted respectively at the upper plane of guide rail 1 and lower plane.Motor 3 is arranged on support 2, and drive 4 rotates and is arranged on support 2, and motor 3 drives drive 4 to rotate, and drive 4 drives cylinder blade 5 to rotate.Cylinder blade 5 is arranged on swing mechanism, and swing mechanism driver plate blade is presented periodical and swung.Swing mechanism comprises swing span, and swing span is provided with three hinged ends in angular distribution, and three hinged end distributions are hinged on support 2, cylinder blade 5 and drive 4.
Swing span comprises swing arm 6 and support arm 7, and one end of swing arm 6 is hinged on support 2, and the other end is hinged with cylinder blade 5, and support arm 7 is arranged between drive 4 and swing arm 6, and one end of support arm 7 is hinged on drive 4, and the other end is connected in swing arm 6.The side of drive 4 is provided with rotational pin, and rotational pin is positioned at the position away from drive 4 pivot center, and one end and the rotational pin of support arm 7 are hinged.When drive 4 rotates, support arm 7 drives swing arm 6 to swing, and makes cylinder blade 5 present periodical and swings.
As shown in Figure 2, support arm 7 is extensible arm, comprises the first support arm 71 and the second support arm 72, first support arm 71 is socketed in the trepanning 721 of the second support arm 72, and be provided with spring 73 in trepanning 721, the first support arm 71 is connected with the second support arm 72 elasticity.Second support arm 72 is provided with stop screw 74, one end of stop screw 74 wears in trepanning 721, first support arm 71 is provided with stopper slot 711, one end that stop screw 74 is positioned at trepanning 721 wears stopper slot 711, and the first support arm 71 and the second support arm 72 limit the collapsing length of support arm 7 by stop screw 74 and the position-limiting action of stopper slot 711.
As shown in figures 1 and 3, drive 41 between motor 3 and drive 4 by the first driving-chain, drive 4 and cylinder blade 5 are driven by the second driving-chain 42, and the second drive chain 42 is provided with strainer 8.Strainer comprises regulating wheel 81, nutted rod 82, backstand 83 and elastic component 84, backstand 83 is fixed on support 2, one end of nutted rod 82 is slidably connected on backstand 83, the other end and regulating wheel 81 hinged, elastic component 84 is arranged between nutted rod 82 and backstand 83, makes regulating wheel 81 carry out tensioning by the elastic force of elastic component 84 to the second drive chain 42.
