Abstract

The utility model discloses a device is cut to diaphragm, it includes knife rest, slider, swing track, connecting rod and crank, the both ends fixed connection of slider and knife rest, the bottom and the swing track cooperation of slider slide, the one end and the slider of connecting rod are articulated, the other end and the articulate one end of connecting rod are articulated, the articulate other end is fixed in swing motor's pivot. The utility model provides a device is cut to diaphragm, blade to the transverse force of diaphragm when it can reduce the cutting.

Description

Diaphragm slitting device

Technical Field

The utility model relates to a device is cut to diaphragm.

Background

At present, the process of cutting is the diaphragm of cutting the great diaphragm of width into the required width of customer, and in the process of cutting, common easy-to-wear article is the slitting blade, and common blade on the market is straight sword at present, is immovable when nevertheless straight sword uses, and at the in-process of cutting, can be in the position of blade and diaphragm contact, the fixed point wearing and tearing produce the opening, can cause the defect of cutting when follow-up slitting diaphragm.

In the CN201820775790.4 patent, a solution to the above problem is proposed. There are several disadvantages in this scheme: because the adopted blade moving mode is that the cutter shaft rotates as the center, the available width of the cutter is narrower when the cutter rotates, and the service life is prolonged. When the cutter rotates, transverse force is applied to the diaphragm, and the diaphragm at the slitting part deforms. Affecting the final product yield.

Disclosure of Invention

The utility model aims to solve the technical problem that, overcome prior art not enough, provide a device is cut to diaphragm, blade is to the transverse force of diaphragm when it can reduce the cutting.

In order to solve the technical problem, the technical scheme of the utility model is that:

the utility model provides a device is cut to diaphragm, it includes knife rest, slider, swing track, connecting rod and crank, the both ends fixed connection of slider and knife rest, the bottom and the swing track cooperation of slider slide, the one end and the slider of connecting rod are articulated, the other end and the articulate one end of connecting rod are articulated, the articulate other end is fixed in swing motor's pivot.

Further, the knife rest is uniformly provided with blades.

Further, the included angle alpha between the blade and the diaphragm during cutting is 0-30 degrees.

Further, the moving amplitude of the sliding block on the swinging track is larger than the length of the blade.

Further, the moving frequency of the slide block on the swing track is between 1 to 20 to-and-fro/min.

Having adopted above-mentioned technical scheme, the utility model discloses a set up crank connecting rod and slider at knife rest both ends, make the blade be reciprocating motion on swing track, the blade improves yield and efficiency of cutting to the transverse force of cutting the diaphragm when having reduced the cutting, can promote the application range and the life-span of blade simultaneously by a wide margin.

Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

As shown in figures 1 and 2, the diaphragm cutting device comprises a knife rest 4, a sliding block 2-1, a swinging track 2-2, a connecting rod 3-2 and a crank 3-1, wherein blades 1 are uniformly arranged on the knife rest 4, the sliding block 2-1 is fixedly connected with two ends of the knife rest 4, the bottom of the sliding block 2-1 is matched with the swinging track 2-2 to slide, the swinging track 2-2 is fixed on one side of the wall of the cutting machine, one end of the connecting rod 3-2 is hinged with the sliding block 2-1, the other end of the connecting rod 3-2 is hinged with one end of the crank 3-1, the other end of the crank 3-1 is fixed on a rotating shaft of a swinging motor 3, and the swinging motor 3 is fixed on the other side of. The diaphragm 5 is transported in the vertical direction, the blade 1 is tangent to the diaphragm 5 after extending out, the included angle alpha between the blade 1 and the diaphragm 5 is 0-30 degrees when cutting, the moving amplitude of the sliding block 2-1 on the swinging track 2-2 is larger than the length of the blade 1, and the moving frequency of the sliding block 2-1 on the swinging track 2-2 is between 1 to 20 to/fro/min.

During cutting, the swing motor 3 rotates to drive the crank 3-1 on the motor rotating shaft to rotate, the crank 3-1 drives the connecting rod 3-2 to swing, the connecting rod 3-2 drives the sliding block 2-1 to move back and forth on the swing track 2-2, so that the blade 1 does reciprocating motion, the reciprocating frequency of the blade 1 is changed by adjusting the frequency of the swing motor 3, meanwhile, because the included angle between the blade 1 and the diaphragm 5 is small, when the blade 1 does reciprocating motion, the transverse acting force generated on the diaphragm 5 is small, so that the transverse force caused by the movement of the blade 1 during cutting of the diaphragm 5 is reduced, meanwhile, because the movement along the direction of the blade 1 is adopted, the use range of the blade 1 can be greatly improved, the utilization rate of the blade 1 is improved, and the service life of the blade 1 is greatly prolonged.

The above embodiments further describe the technical problems, technical solutions and advantages of the present invention in detail, it should be understood that the above embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
