Description

Technical Field

[0001] This utility model relates to the field of engraving machine technology, specifically a waste collection device for CNC engraving machines. Background Technology

[0002] CNC engraving machines, also known as numerical control engraving machines, are precision numerical control equipment. With the development of the engraving industry, the market has placed higher demands on engraving machine manufacturers. The market segmentation in the engraving industry has become increasingly mature, and CNC engraving meets the needs of large-scale production while offering a simpler user interface. During operation, the engraving machine removes debris from the raw material. This debris falls onto the worktable, and after completion, it needs to be processed to prevent it from affecting the engraving of the next material; therefore, a waste recycling device is required.

[0003] According to the authorization announcement number CN220029527U, a rapid waste collection device for CNC engraving machine processing table is disclosed, including an engraving machine processing table. Vertical frames are fixed on both sides of the engraving machine processing table, and the engraving components of the engraving machine are installed between the vertical frames. A horizontal limiting frame is installed on the inner wall of the vertical frames. A height adjustment component is fitted to the side wall of the horizontal limiting frame. A crossbar is installed on the side wall of the height adjustment component. A horizontal slide rail is installed on the side wall of the crossbar. A corrugated telescopic tube is installed on the side wall of the guide slider of the horizontal slide rail. The end of the corrugated telescopic tube is connected to the air inlet of a vacuum cleaner. The vacuum cleaner is installed on the side wall of the vertical frames.

[0004] A search of the aforementioned patents and analysis of related equipment in existing technologies revealed that while the device does offer some convenience in practical applications by using a vacuum cleaner to collect waste materials on the worktable, most engraving machine worktables currently have T-slots for easy workpiece fixation with pressure plates. During the engraving process, waste chips easily enter these T-slots. This device, relying solely on suction to clean the waste, cannot effectively remove waste materials from the corners of the T-slots, creating blind spots and affecting the thoroughness of waste removal. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a waste collection device for CNC engraving machines. This device has the advantages of waste collection and cleaning, and solves the problem that most engraving machine worktables are equipped with T-slots for easy fixation of workpieces using pressure plates. During the engraving process, waste chips easily enter the T-slots, and this device only relies on suction to clean the waste, which cannot effectively remove the waste at the corners of the T-slots, resulting in a problem of cleaning dead corners.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste collection device for a CNC engraving machine, comprising a worktable, a T-slot, a movable frame, and an engraving head. The movable frame is slidably connected to the top of the worktable. The T-slot is formed on the top of the worktable, and a plurality of T-slots are provided and evenly distributed. The engraving head is slidably connected to the left side of the movable frame. A scraper is provided on the right side of the top of the worktable, and a T-shaped scraper block is fixedly connected to the bottom of the scraper. The number of T-shaped scraper blocks is equal to the number of T-slots. Connecting mechanisms are fixedly connected to the front and rear sides of the bottom right side of the movable frame.

[0007] As a preferred embodiment of this utility model, the connecting mechanism includes an L-plate, which is fixedly connected to the front and rear sides of the bottom right side of the movable frame. A C-plate is fixedly installed on the outer side of the L-plate, and a connector is fixedly connected to the left side of the C-plate. The right side of the scraper is fixedly connected to the connector. Fixing components are provided on the outer side of the L-plate and the left side of the front and back sides of the C-plate.

[0008] As a preferred embodiment of this utility model, the fixing component includes a mounting groove, which is formed on the outer side of the L-plate and the left side of the front and back of the C-plate. A fixing screw is provided inside the mounting groove, and a fixing block is threadedly connected to the outer side of the surface of the fixing screw.

[0009] In a preferred embodiment of this utility model, the connecting member is configured as an electric telescopic rod, the output end of which is fixedly connected to the right side of the scraper, and the right side of which is fixedly connected to the C-shaped plate.

[0010] As a preferred embodiment of this utility model, waste baffles are fixedly connected to the bottom of both the front and back sides of the workbench, and the scraper is located between the two waste baffles.

[0011] As a preferred embodiment of this invention, a collection box is provided on the left side of the workbench.

[0012] As a preferred embodiment of this invention, the fixing block is arranged in a butterfly shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a scraper mounted on the top of the worktable, equipped with T-shaped scrapers equal in number and corresponding to the T-slots. As the moving frame moves, the scraper moves synchronously. The T-shaped scrapers at the bottom of the scraper correspond one-to-one with the T-slots on the worktable. During the scraper's movement, the T-shaped scrapers can penetrate deep into the T-slots, scraping out the waste material. As the scraper moves from the left to the right side of the worktable, the waste material is gradually concentrated and pushed to the right side, thus cleaning the worktable. This solves the problem that most engraving machine worktables have T-slots for easy workpiece fixation with pressure plates, where waste easily enters during engraving. This device, relying solely on suction to clean the waste, cannot effectively remove waste from the corners of the T-slots, creating cleaning dead zones. This invention achieves the effect of waste cleaning and collection.

[0015] 2. By setting up a connecting mechanism, this utility model establishes a reliable connection between the scraper and the moving frame. When the moving frame moves, the L-plate drives the C-plate to move, which in turn drives the scraper to move, ensuring that the moving frame can stably drive the scraper to move, thereby cleaning the waste on the workbench.

[0016] 3. By setting a fixing component, this utility model facilitates the installation and disassembly of the various parts of the connecting mechanism. Through the cooperation of the fixing screw and the fixing block, rotating the fixing screw causes the threaded fixing block to move on the screw, thereby tightly fixing the various parts together. Thus, the cleaning structure can be quickly installed and disassembled when in use and when not in use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides a waste collection device for a CNC engraving machine, including a worktable 1, a T-slot 2, a movable frame 3, and an engraving head 4. The movable frame 3 is slidably connected to the top of the worktable 1. The T-slot 2 is opened on the top of the worktable 1, and there are several T-slots 2 arranged at equal intervals. The engraving head 4 is slidably connected to the left side of the movable frame 3. A scraper 5 is provided on the right side of the top of the worktable 1. A T-shaped scraper block 6 is fixedly connected to the bottom of the scraper 5. The number of T-shaped scraper blocks 6 is equal to the number of T-slots 2. A connecting mechanism 7 is fixedly connected to the front and rear sides of the bottom right side of the movable frame 3.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The connecting mechanism 7 includes an L-plate 71, which is fixedly connected to the front and rear sides of the bottom right side of the movable frame 3. A C-plate 72 is fixedly installed on the outer side of the L-plate 71. A connector 73 is fixedly connected to the left side of the C-plate 72. The right side of the scraper 5 is fixedly connected to the connector 73. Fixing components 74 are provided on the outer side of the L-plate 71 and the left side of the front and back sides of the C-plate 72.

[0024] As a technical optimization of this utility model, by setting the connecting mechanism 7, a reliable connection relationship is established between the scraper 5 and the moving frame 3. When the moving frame 3 moves, the L plate 71 drives the C plate 72 to move, which in turn drives the scraper 5 to move, ensuring that the moving frame 3 can stably drive the scraper 5 to move, thereby cleaning the waste on the workbench 1.

[0025] refer to Figure 1 , Figure 2 and Figure 3 The fixing component 74 includes a mounting groove 741, which is opened on the outer side of the L plate 71 and the left side of the front and back of the C plate 72. A fixing screw 742 is provided inside the mounting groove 741, and a fixing block 743 is threadedly connected to the outer side of the surface of the fixing screw 742.

[0026] As a technical optimization of this utility model, by setting the fixing component 74, the installation and disassembly of each component of the connecting mechanism 7 are facilitated. Through the cooperation of the fixing screw 742 and the fixing block 743, the fixing screw 742 is rotated, and the threaded fixing block 743 moves on the screw, thereby fixing each component tightly together. Thus, the cleaning structure can be quickly installed and disassembled when in use and when not in use.

[0027] refer to Figure 1 , Figure 2 and Figure 3 The connector 73 is set as an electric telescopic rod 731. The output end of the electric telescopic rod 731 is fixedly connected to the right side of the scraper 5, and the right side of the electric telescopic rod 731 is fixedly connected to the C-shaped plate 72.

[0028] As a technical optimization of this utility model, by using an electric telescopic rod 731 as a connecting member 73, the pushing stroke of the scraper 5 is effectively increased, which can more thoroughly clean the waste on the surface of the workbench 1, avoid waste residue due to the scraper 5 not being able to reach specific positions, and improve the thoroughness of waste cleaning.

[0029] refer to Figure 1 , Figure 2 and Figure 3 Waste baffles 8 are fixedly connected to the bottom of both the front and back sides of the workbench 1, and scraper 5 is located between the two waste baffles 8.

[0030] As a technical optimization of this utility model, by setting up waste baffles 8 and scraper 5 moving between the two waste baffles 8, the waste baffles 8 can prevent waste from falling from the front and back of the workbench 1 during the scraper 5 cleaning the waste, and guide the waste to move towards the collection box 9 on the right side of the workbench 1, thereby improving the efficiency of waste collection and facilitating the unified treatment of waste in the future.

[0031] refer to Figure 1 , Figure 2 and Figure 3 A collection box 9 is set on the left side of the workbench 1.

[0032] As a technical optimization of this utility model, when the scraper 5 cleans the waste from the left side of the workbench 1 to the right side, the waste falls directly into the collection box 9, thereby achieving centralized collection of waste.

[0033] refer to Figure 1 , Figure 2 and Figure 3 The fixing block 743 adopts a butterfly-shaped design.

[0034] As a technical optimization of this utility model, by setting the fixing block 743 as a butterfly shape, the butterfly-shaped fixing block 743 can be easily rotated by the operator by hand without the need for additional tools. When installing or disassembling the fixing component 74, the fixing block 743 can be quickly tightened and loosened by manually rotating the butterfly-shaped fixing block 743.

[0035] The working principle and usage process of this utility model are as follows: First, the workpiece to be engraved is fixed using a pressure plate through the T-slot 2 on the worktable 1. The CNC engraving machine is started, and the moving frame 3 drives the engraving head 4 to perform engraving operations on the workpiece. During the engraving process, the engraving head 4 moves along the workpiece surface according to a preset program under the movement of the moving frame 3 to complete the engraving task. Simultaneously, waste material and debris fall into the worktable 1 and the T-slot 2. After engraving is completed, the operator moves the T-shaped scraper 6 into the T-slot 2 and installs the C-plate 72. This is done by inserting the fixing screw 742 into the mounting slot 741 and then tightening it by rotating the fixing block 743, thus fixing the C-plate 72 to the outside of the L-plate 71. Next, the operator controls the moving frame 3 to move to the left. As the moving frame 3 moves, it drives the scraper 5 to move synchronously. The T-shaped scraper 6 at the bottom of the scraper 5 and the workpiece... The T-slots 2 on the worktable 1 correspond one-to-one. During the movement of the scraper 5, the T-shaped scraper block 6 can penetrate deep into the T-slot 2 to scrape out the waste material inside the T-slot 2. As the scraper 5 moves from the right side to the left side of the worktable 1, the waste material is gradually concentrated and pushed to the left side of the worktable 1, thus cleaning the waste material on the worktable 1. When the moving frame 3 moves to the far left, if there is still a distance between the scraper 5 and the far left side of the worktable 1, the operator controls the electric telescopic rod 731 to extend and push the scraper 5 to continue moving to the left to push the waste material. Under the push of the scraper 5, the waste material is concentrated and pushed to the left side of the worktable 1 and falls into the collection box 9, ensuring that there is no waste material residue inside the T-slot 2. When the cleaning is completed and it is no longer needed, the operator rotates the fixing block 743 to release the fixing screw 742 to disconnect the connection between the C-plate 72 and the L-plate 71, preventing the cleaning mechanism from affecting the normal engraving of the engraving machine.

[0036] In summary, this waste collection device for CNC engraving machines, by setting a scraper 5 on the top of the worktable 1 and equipping it with T-shaped scraper blocks 6 in number and corresponding to the T-slots 2, causes the scraper 5 to move synchronously when the moving frame 3 moves. The T-shaped scraper blocks 6 at the bottom of the scraper 5 correspond one-to-one with the T-slots 2 on the worktable 1. During the movement of the scraper 5, the T-shaped scraper blocks 6 can penetrate deep into the T-slots 2 and scrape out the waste material inside the T-slots 2. As the scraper 5 moves from the left side to the right side of the worktable 1, the waste material is gradually concentrated and pushed to the right side of the worktable 1, thus cleaning the waste material on the worktable 1. This solves the problem that most engraving machine worktables are equipped with T-slots for easy fixation of workpieces using pressure plates. During the engraving process, waste chips easily enter the T-slots, and this device only relies on suction to clean the waste material, which cannot effectively remove the waste material at the corners of the T-slots, resulting in cleaning dead corners.
