Description

Technical Field

[0001] The utility model relates to a vertical electric cutter sharpening device. Background Art

[0002] A vertical electric cutter is a common cloth cutting device that can cut multiple layers of stacked cloth at the same time. It has the characteristics of high cutting efficiency, smooth incision and simple operation. A vertical electric cutter is usually equipped with a sharpening device. The blade can be sharpened by regularly controlling the sharpening device to move along the blade using a lifting device to prevent the blade from becoming stiff and affecting the cutting effect. However, the existing vertical electric cutter sharpening device usually uses a spring to make the sanding belts on the two sharpening racks close to the blade. Even if the blade is not sharpened, the sanding belts are still in contact with the upper end of the blade. This causes the sanding belt to rub against the upper end of the blade due to the high-speed vibration of the blade, resulting in a fast wear rate of the sanding belt, a short service life, and the need to frequently replace the sanding belt. Therefore, it is necessary to develop a vertical electric cutter sharpening device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0017] See also Figures 1 to 4The sharpening device of a vertical electric cutter shown in the figure comprises a mounting plate 11, the mounting plate 11 is provided with an adjusting cavity 24, a bidirectional threaded rod 25 is rotatably arranged in the adjusting cavity 24, the bidirectional threaded rod 25 is provided with two sections of threads in opposite directions, the bidirectional threaded rod 25 is provided with two adjusting blocks 19, both adjusting blocks 19 are provided with a sharpening frame 12, a mounting sleeve 13 is slidably arranged on the sharpening frame 12, a roller 2 16 is rotatably arranged on the mounting sleeve 13, a roller 15 is rotatably arranged on the sharpening frame 12, an abrasive belt 17 is arranged between the roller 15 and the roller 2 16, a ceramic sheet 23 is arranged on one side of the sharpening frame 12, a support column 22 is connected between the ceramic sheet 23 and the sharpening frame 12, and the abrasive belt 17 bypasses the surface of the ceramic sheet 23; the two adjusting blocks 19 are respectively arranged on the two threaded sections on the bidirectional threaded rod 25, when the bidirectional threaded rod 25 is rotatably arranged, the two adjusting blocks 19 are provided with a sharpening frame 12, and the two adjusting blocks 19 are provided with a sharpening frame 12. When the threaded rod 25 rotates, the two adjustment blocks 19 can be controlled to move closer to or farther from each other, thereby controlling the two sharpening racks 12 to move closer to or farther from each other. When sharpening is not required, the two sharpening racks 12 are controlled to move away from each other, so that the two sanding belts 17 maintain a certain distance from the blade, thereby avoiding the loss of the sanding belts 17 in the non-sharpening stage and extending the service life of the sanding belts 17. When sharpening is required, the two sharpening racks 12 are controlled to move closer to each other, so that the two sanding belts 17 are in contact with the blade of the blade, and then the lifting device of the vertical electric cutter is started to control the entire sharpening device to move along the blade to perform sharpening; the part of the sanding belt 17 that bypasses the surface of the ceramic sheet 23 is the part where the sanding belt 17 contacts the blade. While the support column 22 and the ceramic sheet 23 support the sanding belt 17, the part of the sanding belt 17 that bypasses the surface of the ceramic sheet 23 can be properly tilted, so that the sanding belt 17 can better fit the blade.

[0018] Furthermore, a strip groove 14 is provided on the sharpening frame 12, and a slide plate 26 is provided on the inner side of the mounting sleeve 13. The slide plate 26 is slidably connected to the strip groove 14, and a spring 27 is provided between the slide plate 26 and the inner wall of the strip groove 14; when the sanding belt 17 needs to be replaced, the mounting sleeve 13 is slid along the sharpening frame 12 to shorten the distance between the roller 15 and the roller 2 16, and the sanding belt 17 can be removed from between the roller 15 and the roller 2 16 for replacement.

[0019] Furthermore, a limiting bolt 18 is provided at one end of the sharpening frame 12, and a matching nut is provided on the limiting bolt 18, and the limiting bolt 18 passes through the strip groove 14; the spring 27 is in a compressed state, and the elastic force of the spring 27 is applied to the slide plate 26, so that the ceramic sheet 23 is tightly pressed against the limiting bolt 18, and the roller 2 16 is kept away from the roller 1 15, so that the sanding belt 17 between the roller 15 and the roller 2 16 is tightened to prevent the sanding belt 17 from loosening and falling off.

[0020] Furthermore, a motor 20 is provided on one side of the mounting plate 11, and the output shaft of the motor 20 is connected to the bidirectional threaded rod 25; starting the motor 20 can control the bidirectional threaded rod 25 to rotate forward or reverse, thereby controlling the adjustment blocks 19 to move closer or farther away from each other.

[0021] Furthermore, a mounting hole 21 is provided on the mounting plate 11, and the mounting hole 21 is arranged on one side of the adjusting cavity 24; there are two mounting holes 21, one of which is a threaded hole for connecting to the lifting device of the vertical electric cutter, and the other mounting hole 21 is a through hole for allowing the protective rod of the vertical electric cutter to pass through.

[0022] The working principle of the utility model is that when sharpening the knife, the motor 20 is started to rotate the bidirectional threaded rod 25, so that the two adjustment blocks 19 are close to each other, so that the two knife sharpening racks 12 are close to each other, and when the two sanding belts 17 are in contact with the blade of the vertical electric cutter, the lifting device of the vertical electric cutter can be started to control the entire knife sharpening device to move along the blade, so as to sharpen the knife. After the knife sharpening is completed, the motor 20 is started in the reverse direction to reverse the bidirectional threaded rod 25, so that the two knife sharpening racks 12 are away from each other, so that the two sanding belts 17 are separated from the blade of the vertical electric cutter, avoiding continuous wear of the sanding belts 17 in the non-sharpening state, thereby extending the service life of the sanding belts 17.

[0023] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
