Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of engraving facilities, and in particular relates to an electric engraving pen. Background Art
[0002] When engraving ceramics with an electric chisel, it's important to choose the appropriate power and blade head based on the ceramic's hardness and the desired engraving. Generally speaking, higher-power chisels provide greater cutting force and are suitable for harder ceramics, while lower-power chisels are more suitable for finer engraving. Chisel heads come in a variety of shapes, including conical, cylindrical, and flat, each suitable for different engraving effects.
[0003] Since the existing electric engraving cutter is small in size, the high-speed rotation of the drill bit will generate a large amount of dust and mist during the engraving process of ceramics, stone and wood. After engraving the corresponding pattern, the machine needs to be stopped for cleaning in order to improve the accuracy of the next engraving. However, this method has major disadvantages. On the one hand, the powder debris generated during the engraving process will fly in the air, reducing the line of sight between the engraver and the engraving, affecting the user's judgment during engraving, and thus increasing the probability of engraving errors. On the other hand, the powder debris will adhere to the surface of the engraving, causing color difference between the powder debris and the surface of the engraving, which is not conducive to the engraver's control of the engraving depth. Summary of the Invention
[0004] The purpose of the present invention is to provide an electric engraving pen, which can vacuum or spray water on the surface of the engraving object during the engraving process, thereby increasing the engraver's visual clarity and improving the engraving accuracy.

[0027] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.
[0028] like Figure 1-Figure 7 As shown, the electric engraving pen includes an electric engraving pen body 1, a voltage regulator 3 and a mounting ring 2. The voltage regulator 3 is electrically connected to the electric engraving pen body 1 through a wire, and the mounting ring 2 is detachably mounted on the electric engraving pen body 1;
[0029] A groove 4 is provided on the end face of the mounting ring 2, and the groove 4 is distributed in a C shape. The end face of the mounting ring 2 is detachably connected to a sealing ring 20, and a quick connector 19 is fixedly connected to the side wall of the mounting ring 2. A plurality of through holes 5 are provided on the side wall of the mounting ring 2 away from the sealing ring 20, and a dust cleaning component is provided in the through hole 5.
[0030] like Figure 4 and Figure 5 As shown, the dust cleaning assembly includes a conical tube 6 fixedly connected to the side wall of the through hole 5, a silicone tube 7 is sleeved on the conical tube 6, and a shaping tube 8 is fixedly connected to the other end of the silicone tube 7. A flow control assembly is provided on the inner wall of the shaping tube 8 away from one end of the silicone tube 7.
[0031] Among them, the shaping tube 8 can be used in any of the following ways:
[0032] Metal hose: Usually made of metal materials such as stainless steel, it has a spiral or corrugated structure inside and is generally wrapped in a protective sheath. It has good flexibility and bendability and can be bent into various shapes as needed. It can be shaped arbitrarily to a certain extent.
[0033] Plastic hose: Made of various materials, such as PVC, PE, etc. This type of hose is relatively soft and easy to bend and shape. It can be bent into different angles and shapes according to actual needs.
[0034] Silicone tube 7: Made of silicone rubber, it has excellent elasticity and flexibility, and can be easily bent, twisted, and shaped to any shape. It is also resistant to high and low temperatures and chemical corrosion.
[0035] like Figure 3 As shown, the flow control component includes an annular shell 9 fixedly connected to the side wall of the shaping tube 8, and a fixed circular plate 10 is fixedly connected to the inner wall of the shaping tube 8 near the end face. The side wall of the shaping tube 8 is located on one side of the fixed circular plate 10 with an annular groove, and the annular groove is located on the inner side of the annular shell 9. A movable circular plate 11 is rotatably connected in the annular groove. The side walls of the fixed circular plate 10 and the movable circular plate 11 are respectively provided with multiple arc grooves 12, and the arc grooves 12 on both sides correspond to each other. The side wall of the movable circular plate 11 is also provided with a transmission component.
[0036] Specifically, when it is necessary to adjust the flow of the shaping tube 8, first rotate the rotating rod 15 to drive the worm 14 to rotate, and the worm 14 engages the annular worm gear 13 and drives the movable circular plate 11 to rotate, so that the movable circular plate 11 is staggered with the arc groove 12 on the fixed circular plate 10, thereby controlling the flow of air or water in the shaping tube 8. For example, when spraying water, the smaller the space between the arc grooves 12 on both sides, the greater the impact force after the water flow penetrates, and the larger the space, the smaller the impact force; in addition, the use of the annular shell 9, on the one hand, facilitates the connection of the shaping tubes 8 on both sides of the annular groove and plays a supporting role, and on the other hand, it can protect the annular worm gear 13 and the worm 14 to prevent the transmission parts from being exposed and adhering to dust and impurities, affecting their service life and lubrication effect.
[0037] like Figure 3 As shown, the transmission assembly includes an annular worm gear 13 fixedly connected to the side wall of the movable circular plate 11. One side of the annular worm gear 13 is located in the inner cavity of the annular shell 9 and is engaged with a worm 14. The other end of the worm 14 passes through the annular shell 9 and is fixedly connected to a rotating rod 15. The worm 14 is rotatably connected to the annular shell 9.
[0038] In many devices requiring precise angular positioning, such as machine tool table rotation mechanisms and the joints of industrial robots, the self-locking function of the annular worm gear 13 and worm 14 ensures that once adjusted to a specified angle, it will not shift due to external forces or gravity, thereby maintaining machining accuracy and operational stability. This self-locking function prevents the load from causing the worm 14 to reverse due to gravity, ensuring that the device operates in the intended direction and improving system reliability.
[0039] like Figure 7 As shown, the tapered tube 6 has a plurality of triangular protrusions 16 fixedly connected to the inclined surface. The triangular protrusions 16 are annular in structure. The triangular protrusions 16 can increase the friction between the silicone tube 7 and the tapered tube 6. When inserting the silicone tube 7 into the tapered tube 6, the end of the silicone tube 7 can be immersed in hot water to soften it. This allows for good elasticity when inserted into the tapered tube 6, allowing the end of the silicone tube 7 to expand. After cooling, the silicone tube 7 is shaped, thereby increasing the stability of the connection with the tapered tube 6.
[0040] like Figure 5 and Figure 6 As shown, the end of the shaping tube 8 away from the silicone tube 7 is fixedly connected to the guide tube 17, and the inner diameter of the guide tube 17 gradually increases from the end close to the shaping tube 8 to the end away from the shaping tube 8.
[0041] Specifically, the guide tube 17 and the shaping tube 8 can be connected by threaded connection, screw connection, clamping or other connection forms, and the shape of the guide tube 17 can also be set to a cone shape or a flat mouth shape. When engraving, different water spraying or dust suction methods can be selected according to the characteristics of the engraving material to increase its flexibility.
[0042] like Figure 4 As shown, a support pad 21 is fixedly connected to the inner wall of the mounting ring 2, and a bolt 22 is threadedly connected to the inner wall of the mounting ring 2 at a position opposite to the support pad 21. The use of the bolt 22 to fix the mounting ring 2 to the electric engraving pen body 1 is a conventional method. In actual use, users can choose different installation methods according to their needs. In addition, the threaded connection position between the bolt 22 and the mounting ring 2 does not penetrate the groove 4.
[0043] like Figure 2 and Figure 4 As shown, the sealing ring 20 is threadedly connected to the mounting ring 2. By adopting the threaded connection, if there is a lot of dust and impurities adhering to the groove 4, the sealing ring 20 can be disassembled for easy cleaning and maintenance, which increases the convenience during use and prolongs the service life.
[0044] Example 2:
[0045] Based on Example 1, this embodiment discloses another form of use:
[0046] When engraving, the user can insert an external water pipe into the quick connector 19 to inject water, so that the water flows out from the shaping tube 8, thereby flexibly switching between vacuuming and water spraying;
[0047] For example, when carving ceramics or stone, the powder dust generated is small, so you can directly spray water to dissolve the powder and water and flow out; if you are carving wood, the wood generates a lot of powder particles, so you can use vacuuming to prevent the powder particles from flying in the air, thereby increasing the cleanliness of the carving environment and the clarity of vision.
[0048] Example 3:
[0049] Based on Example 1, this embodiment specifically discloses: Figure 2 As shown, the dust cleaning assembly further includes a sealing cap 18 .
[0050] In actual use, the user can choose the number of shaping tubes 8 according to needs. For example, two shaping tubes 8 are selected and installed on the conical tube 6 through the silicone tube 7. The end of one shaping tube 8 is aligned with the engraving position, and the other shaping tube 8 is aligned with the drill position. When spraying water, it can not only rinse the surface of the engraving, but also cool the drill bit; when vacuuming, it can absorb the powder splashed from the engraving position, and can also absorb the powder thrown out by the drill bit.
[0051] The through hole 5 where the shaping tube 8 is not installed can be sealed by inserting a sealing cap 18. The sealing cap 18 can be made of rubber or silicone material and can be pressed into the through hole 5 using its own elastic force to seal the tapered tube 6.
[0052] Example 4:
[0053] The speed control method of the electric engraving pen comprises the following steps:
[0054] S1: Select a voltage regulator 3 corresponding to the working voltage of the electric engraving pen body 1, and electrically connect the electric engraving pen body 1 to the voltage regulator 3;
[0055] S2: When engraving, turn on the power of the voltage regulator 3, and slowly adjust the output voltage knob of the voltage regulator 3 to gradually increase the output voltage to the rated working voltage of the electric engraving pen body 1. At this time, the electric engraving pen body 1 starts normally;
[0056] S3: If you want to increase the rotation speed of the electric engraving pen main body 1, continue to adjust the voltage in small increments. As the voltage increases, the rotation speed of the electric engraving pen main body 1 will increase, and vice versa.
[0057] Among them, the voltage regulator 3 is used to adjust the voltage, thereby controlling the rotation speed of the electric engraving pen body 1, so as to adapt to the needs of different materials, different engraving depths, etc. The specific model is: MODEL: ZY-009.
[0058] The working principle of the present invention is as follows: when the user is engraving, he first installs the corresponding number of shaping tubes 8 according to the engraving requirements, first puts the mounting ring 2 on the electric engraving pen body 1, and tightens the bolt 22 to fix it, then inserts the shaping tube 8 into the tapered tube 6 through the silicone tube 7, and then bends the shaping tube 8 according to the user's engraving habits, so that the guide tube 17 is located on either side of the engraving knife so as not to affect the user's line of sight;
[0059] When vacuuming is required, insert the external air pipe into the quick connector 19 to generate negative pressure in the groove 4, which facilitates the absorption and discharge of dust and debris generated during engraving, thereby increasing the clarity of the engraving vision.
[0060] When it is necessary to spray water during engraving, the external water pipe can be connected to the quick connector 19 to inject water into the groove 4. The water flows through the shaping tube 8 and the guide tube 17 to the surface of the engraving to flush the powder generated during engraving, so that the user can control the engraving depth during engraving.
[0061] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
