Description

Technical Field

[0001] This utility model belongs to the field of cutting bed technology, and specifically refers to a double-guided grinding structure for cutting beds. Background Technology

[0002] A cutting table is a cutting device used in industries such as textiles, apparel, leather, automotive seating, and furniture. In actual production, it is often necessary to cut multiple layers of fabric simultaneously. As the cutting process progresses, the circular blades used to cut the fabric may pick up scraps of cloth, generate heat, and become dull; therefore, sharpening the blades is necessary to ensure smooth cutting.

[0003] Currently, in existing cutting machines, such as Chinese patent CN201410363378.8, the method of sharpening the cutting blade is as follows: a sharpening device is set on one side of the cutting blade. When the cutting blade passes the sharpening position, the sharpening device sharpens one side of the cutting blade. After one side of the cutting blade is sharpened, the sharpening device is rotated to sharpen the other side of the cutting blade, thus completing the sharpening process. The problem with this sharpening method is that it wastes a lot of sharpening time, which is not conducive to improving the efficiency of cutting blade sharpening. Especially when one side of the cutting blade becomes dull, the cutting blade will continue to move downwards for a certain period of time, and the quality of the cut fabric may deteriorate. Utility Model Content

[0004] The purpose of this invention is to provide a dual-guided sharpening structure for cutting beds that is structurally sound, simple in operation, and provides accurate positioning during sharpening.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-4 The diagram shows a double-guided sharpening structure for a cutting bed, comprising a support plate 1, a sharpening bracket 2, a sharpening motor 3, a sliding seat 4, a sharpening wheel assembly 5, and a blade guide seat 6. The support plate 1 has a through hole 11 into which the blade guide seat 6 extends. The sharpening bracket 2 is fixed below the support plate 1 and located on one side of the blade guide seat 6. The sliding seat 4 is slidably mounted on one side of the sharpening bracket 2 via a slide rail slider assembly 41. The sharpening motor 3 and the sharpening wheel assembly 5 are located at opposite ends of the sliding seat 4, and the sharpening motor 3 drives the grinding wheels of the sharpening wheel assembly 5 to rotate via a belt (the belt is not shown in the diagram). A driving device is provided between the sliding seat 4 and the sharpening bracket 2. This driving device can push the sharpening wheel assembly 5 on the sliding seat 4 towards or away from the blade guide seat 6. A first guide structure 7 and a second guide structure 8 are provided between the sharpening wheel assembly 5 and the blade guide seat 6. In this invention, the sharpening wheel assembly is slidably mounted on the sharpening bracket via the sliding seat. The driving device pushes the sharpening wheel assembly closer to the blade guide seat to sharpen the cutting tool on the blade guide seat. Furthermore, to ensure sharpening accuracy, the first and second guide structures are provided between the sharpening wheel assembly and the blade guide seat, thus improving sharpening precision.

[0023] In the above-mentioned dual-guided sharpening structure for a cutting bed, the sharpening wheel assembly 5 includes a grinding wheel bracket 51, two grinding wheels 52, and a grinding wheel shaft 53.
