Description

Technical Field

[0001] The utility model relates to the technical field of porcelain embryo carving, in particular to a porcelain embryo carving knife. Background Art

[0002] Ceramic carved decoration refers to the use of bamboo or iron tools to carve various patterns of different depths and areas on the surface of dried or semi-dried ceramic bodies. The carved decoration on the surface of ceramic bodies includes various techniques such as carving, engraving, scratching, hollowing, combing, and combing dotting. Among them, carving refers to the use of tools such as carving knives to carve patterns on the surface of ceramic embryos. The carving knife techniques are divided into "single-entry side knife technique" and "double-entry straight knife technique". The former has one side of the blade deep and the other side shallow, and the cross-section is inclined; the latter has vertical blades on both sides. The carving lines are wide and narrow, with various turns and changes, and have both line and surface artistic effects. In the prior art, there are many kinds of knife heads for porcelain embryo carving knives according to different carving needs. At the same time, during the carving process, dust will remain on the surface of the porcelain embryo. In order to avoid the dust affecting the quality of the carving, a brush is needed to clean the dust generated by the porcelain embryo carving. The traditional carving knife can only achieve a single carving function. During the carving process, the tool needs to be switched frequently, resulting in a long time for cleaning, which affects the efficiency of porcelain embryo carving. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 , This embodiment provides a technical solution: a porcelain embryo carving knife, including a handle 1 and a folding mechanism 8;

[0021] The knife handle 1: a brush 2 is provided on the outer edge of its left side, and the brush 2 is used to clean the dust generated by the carving on the surface of the porcelain embryo. A slide groove 3 is provided in the middle of the left side of the knife handle 1, and a support plate 4 is provided inside the slide groove 3. A slide column 5 is slidably connected in the slide hole in the middle of the support plate 4, and an engraving cutter head 6 is provided at the left end of the slide column 5. A tension spring 7 is provided between the engraving cutter head 6 and the support plate 4. The tension spring 7 is movably sleeved on the outer arc surface of the slide column 5. The left end of the engraving cutter head 6 is pushed to protrude from the inside of the brush 2 by a folding mechanism 8, and the engraving cutter head 6 is used. When the folding mechanism 8 is released, the engraving cutter head 6 is quickly folded into the inside of the slide groove 3 under the elastic force of the tension spring 7, and the engraving cutter head 6 and the brush 2 are switched for use. An anti-slip rubber sleeve 9 is fixedly sleeved on the right end of the outer arc surface of the knife handle 1, which is convenient for personnel to grip the knife handle 1;

[0022] The folding mechanism 8 is respectively arranged at the right end of the engraving cutter head 6 and inside the slide 3. The folding mechanism 8 includes a limit plate 81 and a limit slide 82. The limit slide 82 is arranged in the middle of the slide 3. The limit plate 81 is arranged at the right end of the engraving cutter head 6. The limit plate 81 is connected to the limit slide 82 in a transverse sliding manner. The limit plate 81 slides transversely in the limit slide 82 to limit the angle of the engraving cutter head 6. The folding mechanism 8 also includes a top plate 83 and a rotating shaft 84. The top plate 83 is respectively located on the upper and lower sides of the engraving cutter head 6. The right end of the top plate 83 is provided with a rotating shaft 84. The rotating shaft 84 is rotatably connected between the front and rear inner walls of the slide 3. A force is applied to the top plate 83 to make the top plate 83 rotate around the rotating shaft 84 in the direction close to the engraving cutter head 6, and the inclined surface of the top plate 83 is used to limit the The positioning plate 81 applies a force to push the engraving cutter head 6 to overcome the elastic force of the tension spring 7 and move to the left. The folding mechanism 8 also includes a torsion spring 85, which is movably mounted on the outer arc surface of the rotating shaft 84. The end of the torsion spring 85 away from the top plate 83 is fixedly connected to the inner wall of the slide groove 3, and the other end of the torsion spring 85 is fixedly connected to the top plate 83. When the pressure on the top plate 83 is released, the top plate 83 is reset under the torsion of the torsion spring 85. The upper and lower surfaces of the top plate 83 are provided with rubber pads 10, which is convenient for applying a force to the surface of the top plate 83. The roller 11 is rotatably connected to the rotating groove in the middle part of the limiting plate 81 through the rotating shaft. The outer arc surface of the roller 11 fits with the top plate 83, reducing the friction between the limiting plate 81 and the top plate 83, making it convenient for the top plate 83 to push the engraving cutter head 6 to move left.

[0023] The working principle of a porcelain embryo engraving knife provided by the utility model is as follows: when the porcelain embryo engraving knife is used, a person grasps the knife handle 1, and the person's fingers apply a force to the top plate 83, so that the top plate 83 rotates around the rotating shaft 84 in the direction close to the engraving knife head 6, and the torsion spring 85 twists to generate a torque. During the rotation of the top plate 83, the roller 11 and the top plate 83 are relatively rotated, and the inclined surface of the top plate 83 is used to apply a force to the limit plate 81, so as to push the engraving knife head 6 to overcome the elastic force of the tension spring 7 and move to the left. When the roller 11 is out of contact with the inclined surface of the top plate 83, the engraving knife head 6 stops moving, and the person continues to press the top plate 83 to prevent the top plate 83 from resetting. Under the action of the elastic force of the tension spring 7 Under the action of the torsion force of the torsion spring 85, the top plate 83 is reset. At this moment, the rightward movement of the engraving head 6 is not restricted. Under the elastic force of the tension spring 7, the engraving head 6 is quickly retracted into the inside of the slide groove 3. At this time, the dust generated by the engraving on the surface of the porcelain embryo can be cleaned by the brush 2. Repeating the above operation is convenient for switching between the engraving head 6 and the brush 2 during the engraving process, thereby improving the efficiency of engraving the porcelain embryo.
