Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and more specifically to a laser engraving nozzle dust extraction device. Background Technology

[0002] Laser engraving generates fumes, which not only pollute the environment but may also have adverse effects on human health. Therefore, when performing laser engraving operations, specialized fume treatment devices are usually used to absorb and filter the generated fumes to ensure a safe and clean working environment.

[0003] Currently, when fumes are generated at the cutting point (i.e., the sprue) during laser engraving and cutting of workpieces, a fume extraction device (which can be a fume purifier or a dust collector) is required to quickly remove the fumes to prevent them from contaminating the workpiece (especially transparent products). Figure 4 As shown;

[0004] However, the suction position of this fumigation device is external, close to the outside of the workpiece. This makes it less targeted in attracting smoke and results in weak suction, which can easily contaminate the workpiece. Utility Model Content

[0005] The purpose of this utility model is to provide a laser engraving nozzle dust extraction device in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] This utility model proposes a laser engraving nozzle dust extraction device, including a support assembly, a stable workpiece placed on the support assembly, and a laser engraving device for cutting the workpiece.

[0008] The support assembly includes a box body, a boss fixed to the top of the box body, several sets of suction holes on the box body, an inner cavity inside the box body, and a suction pipe with one end fixed through the box body and communicating with the inner cavity.

[0009] The workpiece is supported stably against the boss, and several sets of suction holes are connected to the inner cavity. The part of the workpiece to be cut is close to the suction hole, and the other end of the suction pipe is connected to the smoke extraction device.

[0010] As a preferred technical solution of this utility model, the plurality of suction holes are provided in multiple groups, and the workpiece to be cut is provided in multiple groups close to the plurality of suction holes.

[0011] As a preferred embodiment of the present invention, the supporting assembly further includes a positioning component for quickly and stably positioning the workpiece on the boss.

[0012] As a preferred embodiment of the present invention, the positioning component includes an insertion hole at the top of the boss and an insertion rod fixed on the workpiece, wherein the insertion rod is inserted into the insertion hole for fitting.

[0013] As a preferred technical solution of this utility model, the insertion holes are provided in multiple sets and are evenly distributed on the top of the boss, and the insertion rods are provided in multiple sets on the workpiece corresponding to the multiple sets of insertion holes.

[0014] The beneficial effects of this utility model are as follows:

[0015] By pre-activating the fumigation device to generate suction in the suction pipe, inner cavity, and suction hole in sequence, the generated smoke can be directly drawn downwards into the suction hole and into the fumigation device. The smoke is targeted and strongly attracted, improving the ability of the smoke to avoid contaminating the workpiece. The positioning component is designed to speed up the placement of workpieces and improve the efficiency and accuracy of processing. Attached Figure Description

[0021] like Figures 1-3 As shown, this embodiment proposes a laser engraving nozzle dust extraction device, including a support assembly 1, a stable workpiece 2 placed on the support assembly 1, and a laser engraving device 3 for cutting the workpiece 2; first, the workpiece 2 is stably placed on the support assembly 1, and then the laser engraving device 3 cuts the workpiece 2 at the position to be cut, and the cut workpiece 2 is as follows. Figure 2 As shown;

[0022] The specific structure of the support component 1 is shown below:

[0023] The support assembly 1 includes a box body 11, a boss 12 fixed to the top of the box body 11, several sets of suction holes 13 on the box body 11, an inner cavity 14 inside the box body 11, and a suction pipe 15 with one end fixedly inserted into the box body 11 and communicating with the inner cavity 14.

[0024] The workpiece 2 is supported and stable against the boss 12. Several sets of suction holes 13 are connected to the interior of the inner cavity 14. The part of the workpiece 2 to be cut is close to the suction hole 13. The other end of the suction pipe 15 is connected to the smoking device.

[0025] The top of the box 11 has a raised boss 12, and a suction hole 13 is provided at the top of the box 11. The workpiece 2 is to be cut above the suction hole 13. The inside of the box 11 is a sealed cavity 14, which is connected to the suction hole 13. An opening is provided on the outside of the box 11. The suction pipe 15 is inserted into the cavity 14 through the opening and connected. The suction pipe 15 and the opening are sealed (the seal can be made by rubber gasket, compression, or adhesive connection). The suction pipe 15 can be part of the smoking device or connected to the inhalation end of the smoking device.

[0026] The fumigation device is turned on in advance to generate suction in the suction pipe 15, the inner cavity 14 and the suction hole 13 in sequence. When the laser engraving device 3 is cutting the workpiece 2 at the position to be cut, the smoke generated can directly enter the suction hole 13 and be sucked into the fumigation device. The smoke is targeted and strongly attracted, which improves the ability of the smoke to not easily come into contact with the workpiece and contaminate it.

[0027] The system includes multiple sets of suction holes 13, and the workpiece 2 is positioned one-to-one with the multiple sets of suction holes 13. By directly setting multiple sets of suction holes 13 and setting a set of workpiece 2 to be cut above each set of suction holes 13, the generated smoke can enter the inner cavity 14 through the suction holes 13 at different positions, resulting in good smoke uniformity and further improving the ability to resist smoke contamination of the workpiece product. Example 2:

[0028] like Figures 1-3 As shown, the difference between this and Embodiment 1 is that the support assembly 1 also includes a positioning assembly 16 for quickly and stably positioning the workpiece 2 on the boss 12, thereby improving the efficiency and accuracy of placing the workpiece 2 and thus increasing processing efficiency.

[0029] The specific structure of the positioning component 16 is shown below:

[0030] The positioning component 16 includes an insertion hole 161 at the top of the boss 12 and an insertion rod 162 fixed on the workpiece 2. The insertion rod 162 is inserted into the insertion hole 161 and fitted together. The insertion rod 162 is fixed at the bottom of the workpiece 2. The insertion rod 162 on the workpiece 2 is aligned with the insertion hole 161 and fitted together, so that the workpiece 2 is quickly fitted onto the top of the boss 12 for stability.

[0031] The insertion holes 161 are provided in multiple sets and are evenly distributed on the top of the boss 12. The insertion rods 162 correspond one-to-one with the multiple sets of insertion holes 161 on the workpiece 2. By setting multiple sets of insertion holes 161 and insertion rods 162 and matching them one-to-one, the stability of the workpiece 2 after placement is improved.

[0032] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
