Description

Technical Field

[0001] The utility model relates to the technical field of engraving processing, in particular to an engraving mechanism. Background Art

[0002] Molds are key components in the manufacture of optical films and are typically cylindrical in shape. To achieve the specific optical properties of optical films, complex structures such as circular particles or triangular prisms must be precisely engraved on the mold surface. Currently, these molds are primarily manufactured using CNC lathes.

[0003] For optical films with longer widths, the mold's circumference increases. During the engraving process on a mold with an increased circumference, the fixed engraving tool must contact the rapidly rotating mold. This relative motion easily generates friction between the engraving tool and the mold, which in turn causes the tool to heat up. Sustained high temperatures can adversely affect the tool, causing the tool's crystals to become brittle, and even damage or chipping. Such tool damage not only affects the engraving accuracy and surface quality, but can also make the mold's incision shape fail to meet design requirements, thereby affecting the optical performance of the optical film.

[0014] According to one embodiment of the present invention, the air outlet conveys cold air to the air inlet and the air duct; the air suction member and the air blowing member are arranged opposite to each other on the upper and lower sides of the cutter head.

[0015] The beneficial effect of the present invention is that the processing end of the cutter head engraves the mold, and the air outlet of the cooling component supplies air to the air duct and the air inlet, and the processing end of the cutter head is located in the air duct.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] like Figure 1-Figure 3 As shown, Figure 1 This is an application scenario diagram of the engraving mechanism; Figure 2 It is a side view of the engraving mechanism; Figure 3 The diagram shows the partial positions of the cutter head 2, the blowing element 34, and the suction element 35. The engraving mechanism of the present application includes a cutter holder 1, a cutter head 2, and a cooling assembly 3. The cutter holder 1 serves as a support and can be mounted on other components or independently mounted on an object such as a wall. The cutter head 2 is mounted on the cutter holder 1 and is used to engrave the mold 4. The cooling assembly 3 is used to cool the cutter head 2 to prevent it from being in a continuously high temperature state.

[0029] The cooling component 3 includes a blowing member 34 and an air suction member 35. The blowing member 34 and the air suction member 35 are arranged opposite to each other. The blowing member 34 has an air outlet 31, and the air suction member 35 has an air inlet 32. An air duct 33 is formed between the air outlet 31 and the air inlet 32. It can be understood that the air outlet 31 of the blowing member 34 can blow out air, and the blown air flows through the air duct 33 and then enters the air inlet 32 ​​of the air suction member 35. The air suction member 35 can inhale the air flowing out of the air duct 33. Figure 1 and Figure 2F in it is the direction of wind flow. Specifically, the cutter head 2 has a processing end 21, which is responsible for engraving the mold 4. The processing end 21 of the cutter head 2 is located in the air duct 33. When the processing end 21 of the cutter head 2 is engraving the mold 4, the wind in the air duct 33 contacts the processing end 21 of the cutter head 2, and takes out the heat near the processing end 21 of the cutter head 2, and then the air suction part 35 sucks in the wind and transports it to the next designated position, thereby achieving the effect of cooling the cutter head 2. In this embodiment, the blowing part 34 is located on the lower side of the cutter head 2, and the air suction part 35 is located on the upper side of the cutter head 2. Preferably, in order to improve the cooling effect and cooling efficiency of the cutter head 2, the wind blown out by the blowing part 34 through the air outlet 31 is cold wind.

[0030] Furthermore, since the surface of the mold 4 is made of copper, cold air blowing onto the copper surface could cause condensation, leading to rust on the mold 4 and affecting engraving accuracy. Therefore, the air outlet 31 of the blowing member 34 needs to be located close to the bottom of the cutter head 2 (i.e., the area on the lower side closest to the blowing member 34). Furthermore, if the air outlet 31 of the blowing member 34 is too close to the bottom, while this can solve the problem of mold 4 rusting, it can also lead to problems such as reflected airflow diffusing the blowing range and the force exerted by the airflow on the cutter head 2, which can reduce the stability of the cutter head 2. Therefore, the distance between the blowing member 34 and the bottom of the cutter head 2 is L, where L = 10-20 mm.

[0031] Please review Figure 3 Furthermore, the inner diameter of the air outlet 31 of the blowing member 34 is D, and the outer diameter of the cutter head 2 after being directly projected onto the air outlet 31 is S, wherein S<D. Therefore, the wind blown out from the air outlet 31 of the blowing member 34 can basically act on the bottom and sides of the cutter head 2. Preferably, when the cutter head 2 is directly projected onto the air outlet 31 of the blowing member 34, there are blocking areas M between the two side surfaces of the cutter head 2 and the inner edge of the air outlet 31. When in use, part of the wind sent out from the air outlet 31 acts on the bottom of the cutter head 2, and another part flows through the blocking area M and enters the air suction member 35. The setting of the two blocking areas M forms two wind walls, which also serve as the active boundary of the debris 5 generated when the processing end 21 of the cutter head 2 engraves the mold 4, preventing the debris 5 from flying in different directions. The debris 5 will also enter the air suction member 35 along with the wind and be carried out by the air suction member 35. Specifically, the inner diameter D of the air outlet 31 of the blowing member 34 is 10 mm.

[0032] Please continue to review Figure 3The inner diameter of the air inlet 32 ​​of the suction member 35 is H. When the air outlet 31 is projected onto the air inlet 32, the inner diameter H of the air inlet 32 ​​of the suction member 35 will be larger than the inner diameter D of the air outlet 31 of the blowing port. Therefore, the air blown by the blowing member 34 can almost be sucked into the suction member 35, thereby better discharging the debris 5. Preferably, when the air outlet 31 is projected onto the air inlet 32 ​​of the suction member 35, a receiving area N is provided on both sides of the outer edge of the air outlet 31 and the inner edge of the air inlet 32. The provision of the receiving area N allows the air output from the air outlet 31 to be absorbed as much as possible, avoiding any impact on the stability of the cutter head 2, while also removing more debris 5. Specifically, the inner diameter H of the air inlet 32 ​​is 15 mm.

[0033] It should be noted that the blowing member 34 adopts an existing device for conveying cold air, and the suction member 35 adopts an existing device for sucking air, and the specific structures and working principles of the two will not be described in detail.

[0034] To sum up, the processing end 21 of the cutter head 2 engraves the mold 4, and the air outlet 31 of the cooling component 3 supplies air to the air duct 33 and the air inlet 32, and the processing end 21 of the cutter head 2 is located in the air duct 33. When the processing end 21 of the cutter head 2 engraves the mold 4 for a long time and generates high temperature, the wind in the air duct 33 blows through the cutter head 2 and takes out the heat of the cutter head 2, and finally discharges it into the air inlet 32. In this way, the temperature of the processing end 21 of the cutter head 2 can be effectively reduced, and the embrittlement of the processing end 21 of the cutter head 2 caused by high temperature can be avoided, which solves the problem of damage and chipping of the processing end 21 of the cutter head 2, ensures the accuracy and surface quality of the engraving of the mold 4, and thereby reduces the impact on the optical properties of the optical film material; in addition, it can also extend the service life of the cutter head 2 and reduce costs.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
