Detailed Description

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

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

A knife sharpening mechanism of a high-efficiency cloth cutting machine is shown in figure 1 and comprises a cloth cutting knife 1 and a protective cover 11 which is coaxial with the cloth cutting knife 1. The lower end of the protective cover 11 is welded with a U-shaped mounting seat 12, and the cutting edge of the cloth cutter 1 is positioned in a U-shaped notch of the mounting seat 12. As shown in fig. 2, two sets of knife sharpening assemblies 2 are connected in the mounting base 12, and the two sets of knife sharpening assemblies 2 are respectively located at two sides of the cloth cutting knife 1 and are respectively connected with opposite side faces in the notch of the mounting base 12. The sharpening assembly 2 comprises a sharpening block 21 for sharpening the knife and a guide rod 22 for moving the sharpening block 21. The sharpening block 21 is rectangular, and the end face thereof close to the cloth cutter 1 abuts against the cutting edge of the cloth cutter 1. The guide rod 22 is hinged to the end face, away from the cloth cutting knife 1, of the knife grinding block 21, one end, away from the knife grinding block 21, of the guide rod penetrates through the mounting seat 12 and is connected with the mounting seat 12 in a sliding mode, and the axis of the guide rod penetrates through the cutting edge of the cloth cutting knife 1. When the cloth cutting blade 1 is worn and burrs are formed on the cut cloth, a force is applied to the two guide rods 22 toward the cloth cutting blade 1 to move the knife block 21 toward the cloth cutting blade 1, the knife block 21 is brought into contact with the cutting edge of the cloth cutting blade 1, and the knife block 21 and the cloth cutting blade 1 rub against each other to grind the cutting edge of the cloth cutting blade 1. When the knife is sharpened, the cloth cutter 1 is not required to be disassembled any more, and the cloth cutting machine can work all the time, so that the working efficiency of the cloth cutting machine is increased. Meanwhile, the knife grinding block 21 can rotate according to the deflection angle of the cutting edge of the cloth cutting knife 1, so that the knife grinding block 21 can be abutted against the cutting edge of the cloth cutting knife 1, and the knife grinding effect is better.

As shown in fig. 2, since vibration is generated when the cloth slitting machine is operated, the knife block 21 comes into contact with the cloth cutter 1 when grinding is not required, thereby causing unnecessary wear of the cloth cutter 1. Therefore, the guide rods 22 are all sleeved with the springs 23, the guide rods 22 are coaxially welded with the fixing blocks 222, and the fixing blocks 222 are close to the grinding cutter blocks 21. One end of the spring 23 is welded with the end face of the fixing block 222 far away from the cloth cutting knife 1, the other end of the spring is welded with the inner wall of the notch of the mounting seat 12, and the spring 23 is in a stretching state when the knife sharpening block 21 is abutted to the cloth cutting knife 1. The spring 23 applies an elastic force to the knife sharpening block 21 away from the cloth cutting knife 1, so that the knife sharpening block 21 does not contact the cloth cutting knife 1 when the guide rod 22 does not receive a force towards the cloth cutting knife 1, unnecessary abrasion of the cloth cutting knife 1 due to contact with the knife sharpening block 21 is avoided when the cloth cutting knife 1 does not sharpen, and the service life of the cloth cutting knife 1 is prolonged.

As shown in fig. 2 and 3, in order that the knife block 21 does not contact the cloth cutter 1 due to rotation when grinding is not performed, a torsion spring 211 is connected to the knife block 21, the axis of the torsion spring 211 coincides with the axis of the hinge of the knife block 21 and the guide bar 22, one end of the torsion spring 211 abuts against the end surface of the knife block 21 away from the cloth cutter 1, and the other end abuts against the end surface of the guide bar 22. The torsional spring 211 applies elasticity to the sharpening block 21, so that the end face of the sharpening block 21 close to the cloth cutter 1 is perpendicular to the axis of the cloth cutter 1, the sharpening block 21 can not be in contact with the cloth cutter 1 due to rotation when sharpening is not needed, abrasion of the cloth cutter 1 is reduced, and the service life of the cloth cutter 1 is prolonged.

As shown in fig. 2, since the two sharpening blocks 21 are worn after being used for a long time, the sharpening blocks 21 are in contact with each other during sharpening, so that the sharpening blocks 21 cannot abut against the cutting edge of the cloth cutter 1, and the sharpening effect is affected. Therefore, the included angle between the middle point of the two knife sharpening blocks 21 and the connecting line of the axes of the cloth cutter 1 is 25 degrees, so that the two knife sharpening blocks 21 can not be contacted, and the knife sharpening effect can not be influenced.

As shown in fig. 2, since the grinding block 21 generates chips during the friction process with the cloth cutter 1, the chips may adhere to the surface of the grinding block 21, which reduces the roughness of the surface of the grinding block 21 and the speed of grinding the cloth. Therefore, the end surfaces of the sharpening block 21 close to the cloth cutting knife 1 are provided with three chip grooves 212. The chip is discharged from the space between the sharpening block 21 and the cloth cutter 1 through the chip discharge groove 212, so that the roughness of the surface of the sharpening block 21 is not reduced, and the sharpening process is not influenced.

As shown in fig. 2, since the area of the end surface of the guide bar 22 is small, the fingers are exposed to a large pressure by directly pressing the guide bar 22 with hands, and the fingers are easily injured. Therefore, the end surfaces of the guide rods 22 far away from the grinding cutter block 21 are coaxially welded with the pressing blocks 221, and the diameters of the pressing blocks 221 are larger than those of the guide rods 22. The area contacted with the fingers is increased through the pressing block 221, so that the pressure on the fingers is reduced, and the probability of injury of the fingers is reduced.

The working principle is as follows:

when the cutting edge of the cloth cutter 1 is worn, the power of the motor 32 is first turned on to rotate the exhaust fan 31, and then the pressing block 221 is pressed by hand to bring the knife block 21 into contact with the cutting edge of the cloth cutter 1, and at this time, the cloth cutter 1 can be ground as the rotation of the cloth cutter 1 starts to rub against the knife block 21. After finishing sharpening, the fingers are released, and the sharpening block 21 is disengaged from the abutment with the cloth cutter 1 under the action of the elastic force exerted by the spring 23.

The specific embodiments are only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
