Description

Technical Field

[0001] The utility model belongs to the technical field of glass deep processing equipment and relates to a film-coated glass cutting knife. Background Art

[0002] After the large glass is coated, it will be temporarily stored in the warehouse to facilitate subsequent cutting and grinding according to orders. However, since the functional layer in the low-e film is usually a silver layer, it is very easy to oxidize. In order to avoid unnecessary losses caused by scratches on the coating layer during temporary storage, we will use chemical deposition to form a polymer protective film on the coated surface of the coated glass. As for the coated glass, in the subsequent cutting process, since the existing cutting knives are designed for non-coated glass, it is difficult to meet production needs when cutting coated glass, so it is necessary to design a cutting knife specifically for coated glass. Utility Model Content

[0003] The utility model aims to provide a film-coated glass cutting knife to solve the above problems in the prior art, so as to enable the cutting knife to perform cutting operation on the film-coated glass.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a coated glass cutting knife, characterized in that the cutting knife comprises a mounting seat, a connecting tube is provided at the top of the mounting seat, and a mounting groove is provided at the bottom of the mounting seat; a rotating shaft is rotatably connected in the mounting groove through a plurality of bearings, the upper part of the rotating shaft is inserted in each bearing, and a knife seat is installed at the lower part of the rotating shaft; a first through groove is provided at the bottom of the knife seat, a disc-shaped knife wheel is rotatably connected in the first through groove through a short shaft, and the short shaft deviates from the axis of the rotating shaft; the knife wheel is made of tungsten steel, and the top angle of the knife wheel is 135°; a docking groove for connecting the rotating shaft is provided at the top of the knife seat, a second through groove is provided on a side wall of the knife seat above the first through groove, the second through groove is connected to the docking groove, a tension spring is installed in the second through groove, and the middle part of the tension spring is always in close contact with the outer wall of the rotating shaft.

[0005] Preferably, a damping ring is also sleeved on the rotating shaft above the knife seat, and an annular groove is opened on the outer circumferential surface of the damping ring; a torsion spring is fixed to the bottom of the mounting seat by screws, and the damping ring is always clamped at both ends of the torsion spring, and both ends of the torsion spring are located in the annular groove.

[0006] Preferably, a lubricating liquid channel is provided in both the mounting seat and the rotating shaft, and the lubricating liquid channel is in communication with the first through groove.

[0007] The utility model has the advantages:

[0008] 1. The cutter wheel of this cutter is made of tungsten steel, which is harder and more wear-resistant; and the top angle of the cutter wheel is changed from the original 145° to 135°, so that it can meet the requirements of cutting coated glass.

[0009] 2. In the cutting knife, the knife holder is connected to the rotating shaft through a quick-release structure, thereby making the installation and disassembly of the knife holder more convenient.

[0010] 3. In this cutting knife, the existence of the damping ring and the torsion spring can limit the slight turning of the cutter wheel to prevent it from shaking, thereby achieving stable cutting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, a coated glass cutting knife comprises a mounting seat 1, a connecting tube 2 is provided at the top of the mounting seat 1, and a mounting groove is provided at the bottom of the mounting seat 1; a rotating shaft 4 is rotatably connected to the mounting groove through a plurality of bearings 3, the upper part of the rotating shaft 4 is inserted into each bearing 3, and a knife seat 5 is installed at the lower part of the rotating shaft 4; a first through groove 51 is provided at the bottom of the knife seat 5, a disc-shaped knife wheel 53 is rotatably connected to the first through groove 51 through a short shaft 52, and the short shaft 52 deviates from the axis of the rotating shaft 4; the knife wheel 53 is made of tungsten steel, and the top angle of the knife wheel 53 is 135°; a docking groove 54 for connecting the rotating shaft 4 is provided at the top of the knife seat 5, a second through groove 55 is provided on one side wall of the knife seat 5 above the first through groove 51, the second through groove 55 is connected to the docking groove 54, a tension spring 56 is installed in the second through groove 55, and the middle part of the tension spring 56 is always in close contact with the outer wall of the rotating shaft 4.

[0017] In this cutting knife, the connecting tube 2 is provided with an internal thread for connecting the knife rod. When cutting the glass, since the short shaft 52 deviates from the axis of the rotating shaft 4, the rotating shaft 4 automatically rotates under the action of the friction between the cutter wheel 53 and the glass, and the direction of the cutter wheel 53 is adjusted to be consistent with the direction of the cutter, thereby cutting the glass. The cutter wheel 53 of this cutting knife is made of tungsten steel, which is harder and more wear-resistant; and the top angle of the cutter wheel 53 is changed from the original 145° to 135°, so that it can meet the cutting of coated glass. In this cutting knife, a through groove that is connected to the docking groove 54 is opened on one side wall of the knife seat 5, and a tension spring 56 that can always be close to the rotating shaft 4 is provided in the through groove, so that we can use the friction between the tension spring 56 and the rotating shaft 4 to achieve the installation and fixation of the knife seat 5, which can effectively prevent the knife seat 5 from falling, and at the same time facilitate installation and disassembly, so that the knife seat 5 has a quick-release structure.

[0018] like Figure 1 and Figure 2 As shown, a damping ring 6 is also sleeved on the rotating shaft 4 above the knife seat 5, and an annular groove 61 is opened on the outer peripheral surface of the damping ring 6; a torsion spring 8 is fixed to the bottom of the mounting seat 1 by a screw 7, and the damping ring 6 is always clamped at both ends of the torsion spring 8, and both ends of the torsion spring 8 are located in the annular groove 61.

[0019] In the present cutting knife, since the rotating shaft 4 is mounted on the mounting seat 1 through the bearing 3, when cutting the glass, if the surface of the glass is slightly uneven, the cutter wheel 53 will turn or even shake, and thus the glass cannot be cut stably. The damping ring 6 and the torsion spring 8 can limit the slight turning of the cutter wheel 53, so that it does not shake, and thus stable cutting is achieved.

[0020] like Figure 2 As shown, the mounting seat 1 and the selector shaft 4 are both provided with a lubricating liquid channel 9, and the lubricating liquid channel 9 is in communication with the first through groove 51. The lubricating liquid channel 9 is used to continuously provide lubricating liquid to lubricate and cool the cutter wheel, thereby extending its service life.

[0021] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
