Description

Technical Field

[0001] This utility model relates to the field of engraving equipment technology, specifically a protective mechanism for a laser engraving machine. Background Technology

[0002] A laser engraving machine is a device that uses a high-energy laser beam to precisely engrave or cut on the surface of a material. Existing laser engraving machines have integrated their optical systems, processing tables, and exhaust fans according to the needs of individual users, allowing the laser engraving machine to be used by placing small items or directly on items.

[0003] The existing laser engraving machine is equipped with a light-blocking and dust-proof cover that can isolate the smoke and dust generated when lasers process objects, and at the same time, the smoke and dust generated are discharged from the laser engraving machine through the pipes connected to the fan by the exhaust fan.

[0004] During the batch printing process, it was found that because the laser engraving of small laser engraving machines is often less than one second, the exhaust efficiency of the generated smoke and dust is poor. If users wait until the smoke and dust are exhausted as much as possible before opening the light-blocking and dustproof cover to change the engraved item, it is easy to indirectly increase the time spent processing an item, which is more time-consuming.

[0005] To address the aforementioned issues, a protective mechanism for laser engraving machines is proposed. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the prior art by proposing a protective mechanism for a laser engraving machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a protective mechanism for a laser engraving machine, comprising a housing and a dust cover, wherein a laser head and a processing surface are arranged opposite to each other on the housing, the dust cover has a cross-section in the shape of a U-shape and can surround the processing space between the laser head and the processing surface with the housing, an exhaust fan is fixedly installed on the housing with one side connected to the processing space, the exhaust fan is located away from the processing surface, a guide component is provided between the housing and the dust cover for guiding one end of the dust cover close to the processing surface to move away from the processing surface, and then continuing to guide its deflection, and a pusher is provided on the dust cover for fanning air towards the location of the exhaust fan;

[0008] When the vertical cross-section of the processing space is reduced to a triangular shape, the dust cover abuts against the housing towards the inner end face of the exhaust fan.

[0009] The present invention is further configured such that: the guide component includes two sets of guide rails symmetrically distributed on both sides of the housing and a linkage block; the linkage block slides along the guide rail; the linkage block is connected to the dust cover; the guide rail is fixedly connected to the housing; and when the linkage block slides in the guide rail, it can keep both ends of the dust cover in contact with the side wall of the housing.

[0010] The present invention is further configured such that: the area of ​​the guide rail for accommodating the sliding of the linkage block includes a diagonal shift area, a rotation area and a locking area connected in sequence; the diagonal shift area and the rotation area can both guide the linkage block away from the processing surface; when the linkage block is in the locking area, the lower end of the dust cover is kept at a distance from the processing surface.

[0011] The present invention is further configured such that: the dust cover is provided with a plurality of adjustment holes spaced apart along the direction of the oblique shift area, and the linkage block is fixedly connected to the adjustment holes by threaded engagement.

[0012] The present invention is further configured such that: the wind-pushing component includes a fan plate disposed inside the dust cover and two handles disposed outside the dust cover, the two handles being fixedly connected to a rotating rod on one side of the fan plate, and the rotating rod being rotatably connected to the dust cover.

[0013] The present invention is further configured such that: the fan plate is fitted to the dust cover and faces the inner end face of the exhaust fan, and the lower end of the fan plate can be tangent to the processing surface.

[0014] In summary, this utility model has the following beneficial effects: the processing space containing smoke and dust is separated from the processed items by a dust cover, which, while maintaining operational convenience, allows the smoke and dust to be more effectively drawn away from the laser engraving machine, effectively shortening the processing time for each item during mass production.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] A protective mechanism for a laser engraving machine, such as Figures 1 to 7 As shown, the device includes a housing 1 and a dust cover 2. The housing 1 is provided with a laser head 11 and a processing surface 12 arranged opposite to each other. The dust cover 2 has a U-shaped cross-section and can surround the processing space between the laser head 11 and the processing surface 12 together with the housing 1. That is, when the dust cover 2 is in the state of normally covering the processing space, the laser head 11 can emit an unobstructed laser towards the processing surface 12. The middle position of the processing surface 12 is designed as a detachable structure, so that the laser emitted by the laser head 11 can pass through the detached area and through the housing 1 at the processing surface 12. The cross-section and vertical section of the processing space are both rectangular at this time, and the maximum area that can be processed is also rectangular.

[0025] To remove fumes generated within the processing space, an exhaust fan 13 with one side connected to the processing space is fixedly installed on the housing 1. In this embodiment, the exhaust fan 13 is positioned away from the processing surface 12. A guide component is provided between the housing 1 and the dust cover 2 to guide one end of the dust cover 2, which is close to the processing surface 12, to move away from the processing surface 12 and then continue to guide its deflection. The dust cover 2 is provided with a pusher 3 that can fan air towards the exhaust fan 13. That is, after the laser engraving machine finishes processing the item, the operator can push the fumes towards the exhaust fan 13 through the pusher 3. At the same time, by guiding the dust cover 2 to move along a preset path, the fumes can be further guided to the position of the exhaust fan 13. In other words, the vertical cross-section of the processing space can be reduced to a triangular shape in a short time. In this state, the inner end face of the dust cover 2 facing the exhaust fan 13 abuts against the housing 1. See details below. Figure 7 In this state, the housing 1 and the dust cover 2 have two line contact positions. At this time, the processing space containing the dust and the workpiece are separated in space by the dust cover 2. The way to operate the dust cover 2 is the same as the existing method of lifting the dust cover 2 to expose the workpiece. While maintaining the convenience of operation, the dust is more effectively drawn away from the laser engraving machine, which effectively shortens the processing time of each item in mass production.

[0026] like Figure 2 , Figure 3 as well as Figure 6 As shown, the guide assembly includes two sets of guide rails 14 symmetrically distributed on both sides of the housing 1 and a linkage block 4. The linkage block 4 slides along the guide rail 14 and is connected to the dust cover 2. The guide rail 14 is fixedly connected to the housing 1. In order to ensure that the dust does not spill laterally during the process of being sucked by the exhaust fan 13, the linkage block 4 can keep the two ends of the dust cover 2 in contact with the side wall of the housing 1 when it slides in the guide rail 14. Specifically, the area of ​​the guide rail 14 used to accommodate the sliding of the linkage block 4 includes a diagonal sliding area 141, a rotating area 142 and a locking area 143 connected in sequence. The diagonal sliding area 141 and the rotating area 142 can both guide the linkage block 4 away from the processing surface 12. When the linkage block 4 is in the locking area 143, the lower end of the dust cover 2 is kept at a distance from the processing surface 12. That is, when the linkage block 4 is in the diagonal sliding area 141, the rotating area 142 and the locking area 143, it can ensure that the dust does not spill laterally during the process of being sucked by the exhaust fan 13.

[0027] Because the vertical displacement of the linkage block 4 in the inclined zone 141 is equal to the lifting height of the end of the dust cover 2 near the working surface, and considering that the thickness of different items is different, the vertical distance that the dust cover 2 needs to move up and then make room is also different. The dust cover 2 is provided with several adjustment holes 21 spaced apart along the direction of the inclined zone 141, and the linkage block 4 is fixedly connected to the adjustment holes 21 by threaded engagement.

[0028] like Figure 3, Figure 4 as well as Figure 5 As shown, when the linkage block 4 is moving within the rotation zone 142, the dust cover 2 can keep the smoke and dust away from the operator's position. Before that, in order to further increase the speed at which the smoke and dust approach the exhaust fan 13, the pusher 3 includes a fan plate 32 disposed inside the dust cover 2 and two handles 31 disposed outside the dust cover 2. The two handles 31 are fixedly connected to the rotating rod on one side of the fan plate 32, and the rotating rod is rotatably connected to the dust cover 2. When the linkage block 4 is moving within the oblique shift zone 141, while holding the handle 31 to lift the dust cover 2, the handle 31 can be pushed away from its rotation axis towards the exhaust fan 13, so that the fan plate 32 reduces the space for the smoke and dust to diffuse and pushes the smoke and dust towards the exhaust fan 13.

[0029] To make efficient use of the space on the processing surface 12, the fan plate 32 is fitted to the inner end face of the dust cover 2 facing the exhaust fan 13, and the lower end of the fan plate 32 can be tangent to the processing surface 12.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
