Description

Technical Field

[0001] The utility model relates to the field of glass processing equipment, in particular to an elastic knife structure for glass scribing. Background Art

[0002] As a hard and transparent material, glass has been widely used in life. Different equipment is needed to process glass in different application scenarios. For example, the patent with authorization announcement number CN209702576U and the patent with application publication number CN112429956A both disclose devices for marking lines on glass. However, in existing glass marking devices, the engraving knife used for marking is usually fixed, and the glass will inevitably vibrate slightly during the sliding process. At this time, the vibrating glass contacts the fixed engraving knife, which easily causes the engraved line to deviate, and there is also a risk of breaking the glass. Therefore, there is a need for an elastic engraving knife with elasticity for glass marking. Summary of the Invention

[0022] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the figures only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0024] Example 1:

[0025] like Figures 1 to 3 As shown, an elastic knife structure for glass scoring includes a blade 1, a knife holder 2, a power structure 3 for controlling the movement of the knife holder 2 in the vertical direction, and a support structure 4; the knife holder 2 includes an elastic knife plate 23, and the blade 1 is arranged on the knife plate 23; the knife holder 2 is connected to the power structure 3 by transmission, and the power structure 3 controls the knife holder 2 to move up and down in the vertical direction, so that the knife holder 2 is close to or away from the support structure 4, and the glass transported on the support structure 4 is slid and engraved. It should be noted that the glass transported on the support structure 4 adopts the existing structure; the knife holder 2 is also slidably arranged above the support structure 4; the elastic knife plate 23 absorbs the vibration transmitted to the knife holder 2 during the glass scoring process, and makes the blade 1 on the knife plate 23 better cooperate with the glass to complete the sliding engraving process.

[0026] The power structure 3 includes a rotating shaft 31, a power source 32, and a cam 33. The rotating shaft 31 is fixedly arranged above the support structure 4 through a support frame, and the rotating shaft 31 is rotatably connected to the support frame. At least one cam 33 is fixedly arranged on the rotating shaft 31, and the rotating shaft 31 is also transmission-connected to the power source 32. In this example, the power source 32 is also connected to the support structure 4 through the support frame. The power source 32 uses a servo motor to facilitate the control of the rotation and stop angles of the rotating shaft 31. The cam 33 contacts the upper surface of the tool holder 2. An elastic member 42 for resetting is also provided between the tool holder 2 and the support structure 4. When the cam 33 rotates, since the distance between the edge of the cam 33 and the axis of the rotating shaft 31 connected to the cam 33 is constantly changing, the tool holder 2 in contact with the bottom of the cam 33 will also move up and down, thereby realizing the reciprocating motion of the tool holder 2 in the vertical direction.

[0027] The support structure 4 is provided with guide posts 41 for sliding connection with the tool holder 2. The tool holder 2 is provided with sliding bearings 21 corresponding to the guide posts 41. The tool holder 2 is slidably connected to the guide posts 41 via the sliding bearings 21. In this example, two guide posts 41 are provided above the support structure 4, one at each end of the tool holder 2. A spring 42 is also sleeved around the outer periphery of the guide posts 41, providing an upward elastic force to the tool holder 2, helping it to return to its original position.

[0028] The tool holder 2 includes a tool base 22 and a tool plate 23; a plurality of detachable tool plates 23 are fixedly mounted on the tool base 22, and the tool base 22 is in contact with the cam 33; a plurality of blades 1 are mounted on the tool plate 23. The tool plate 23 is in the shape of a long, square, thin plate; the edges of adjacent tool plates 23 are in contact with each other or spaced apart by a set distance; the tool plate 23 is configured as an elastic thin plate to better absorb the vibration generated by the sliding of the blade 1, and to facilitate the bending of the tool plate 23 under the pressure of the blade, so that the blade can better fit the periphery of the glass rod; the combination of the plurality of independent tool plates 23 mounted on the tool base 22 allows the tool plates 23 at different locations to bend separately to accommodate glass rods with different outer diameters. The tool plate 23 is provided with a thin elastic area, which makes it easier for the tool plate 23 as a whole to undergo elastic deformation, allowing the blade 23 to remain in contact with the periphery of the glass rod.

[0029] The upper surface of the knife platform 22 is a horizontal surface, which contacts the cam 33; the lower surface of the knife platform 22 is an inclined surface, which is arranged in contact with the knife plate 23; the blade 1 is provided at the downwardly inclined end of the knife plate 23.

[0030] The blades 1 provided on the knife plate 23 are spaced apart by a set distance, which is related to the gap between the lines drawn on the glass.

[0031] The blade 1 is rotatably connected to the blade holder 2. The blade 1 is in the shape of a circular sheet, so that the blade 1 can achieve marking while rolling.

[0032] During the implementation process, the tool holder 2 is provided with an elastic tool plate 23, and the blade 1 is connected with the tool plate 23. The tool plate 23 absorbs the vibration transmitted to the tool holder 2 during the glass scratching process, so that the blade 1 on the tool plate 23 can better cooperate with the glass to complete the sliding carving process; by arranging a plurality of tool plates on the tool stand, the blade on the tool plate can better fit the contour of the outer periphery of the glass rod; by arranging a rotatably connected circular blade 1 on the tool plate 23, the blade 1 can scratch while rotating, ensuring the stability of the scratching.

[0033] The above description is merely a specific example of the present invention and does not constitute any limitation thereto. It is obvious that those skilled in the art, after understanding the content and principles of the present invention, may make various modifications and changes in form and details without departing from the principles and structure of the present invention. However, such modifications and changes based on the concept of the present invention are still within the scope of protection of the claims of the present invention.
