A dust collector for laser cutting

Abstract

This utility model relates to a dust collector for laser cutting, including a dust collector housing. An air inlet is located on the side of the housing, consisting of an air inlet box and an air inlet. The air inlet box is connected to the side of the housing, and the air inlet is connected to the bottom of the air inlet box. Above the air inlet, the air inlet box has a ramp sloping towards one side of the housing. An impact-breaking mechanism is installed inside the air inlet box. When molten, sparking debris from cutting metal is drawn into the air inlet box, the high-speed airflow causes it to impact the ramp inside the box, breaking larger debris particles. Smaller particles are then further broken down by the impact-breaking mechanism. Combined with the airflow generated during the intake, the smaller debris particles cool and extinguish, preventing them from igniting flammable materials and ensuring high safety.

Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically a dust collector for laser cutting. Background Technology

[0002] Laser cutting equipment generates a large amount of smoke and dust when cutting metal materials. Therefore, a dust collector is needed to collect and treat the smoke and dust generated by laser cutting. Existing laser cutting dust collectors mainly use impellers or fans to create negative pressure inside the dust collector housing. The smoke and dust generated by laser cutting are drawn into the dust collector housing through the air inlet and filtered by the filter cartridges built into the dust collector housing to remove debris and dust, thereby purifying the air.

[0003] However, during laser cutting, molten debris is generated and splashed. When using a traditional dust collector, the dust collector may contain flammable materials such as filter cartridges. If the molten, sparking debris is sucked into the dust collector, it can easily cause a fire due to contact with the flammable materials. Utility Model Content

[0004] The purpose of this invention is to provide a dust collector for laser cutting, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A dust collector for laser cutting includes a dust collector housing with an air inlet on the side of the housing. The air inlet consists of an air inlet box and an air inlet. The air inlet box is arranged in a communicating manner on the side of the dust collector housing, and the air inlet is arranged in a communicating manner at the bottom of the air inlet box. The air inlet box has a slope above the air inlet that slopes towards one side of the dust collector housing. An impact fragmentation mechanism is provided inside the air inlet box to impact and fragment molten sparks until they are extinguished.

[0007] As can be seen, the molten metal fragments with sparks generated from cutting metal are sucked into the air inlet box. Due to the high-speed airflow, the molten fragments can be driven to impact the ramp inside the air inlet box, breaking up the large molten fragments. Then, the small molten fragments continue to impact and break down into even smaller particles through the impact crushing mechanism. Combined with the airflow generated during air intake, the small fragments after impact are cooled and extinguished. Therefore, after entering the dust collector box, they will not cause flammable materials to catch fire, resulting in high safety.

[0008] Furthermore, the impact fragmentation mechanism includes several impact plates A, several impact plates B, and several impact plates C. Several impact plates A are arranged in an array within the air inlet box along the width direction of the air inlet box and are located downstream of the air inlet. Several impact plates B are arranged in an array within the air inlet box along the width direction of the air inlet box and are located downstream of the impact plates A. Several impact plates C are arranged in an array within the air inlet box along the width direction of the air inlet box and are located downstream of the impact plates B. Impact plates A, B, and C all extend vertically.

[0009] Furthermore, an inlet gap A is formed between two adjacent impact plates A, and each impact plate B corresponds to each inlet gap A in position, forming an inlet gap B between two adjacent impact plates B. The impact plate C corresponds to each inlet gap B in position, forming an inlet gap C between two adjacent impact plates C.

[0010] Furthermore, frame-shaped scraping sleeves are slidably fitted on impact plates A, B, and C. The frame-shaped scraping sleeves are connected to each other by corresponding connecting arms to form a scraping sleeve assembly. The air inlet box is equipped with a drive mechanism for adjusting the scraping sleeve assembly by lifting.

[0011] Furthermore, the drive mechanism includes a mounting base, an electric push cylinder, and a connector. The electric push cylinder is vertically fixed to the top of the air inlet box via the mounting base. The telescopic rod of the electric push cylinder extends through into the air inlet box, and a connector is fixed to the end of the telescopic rod. The connector is fixedly connected to two of the connecting arms.

[0012] Furthermore, the air inlet box is fixedly connected to the side of the dust collector box via flange A located on its side, and the air inlet is fixedly connected to the bottom of the air inlet box via flange B located on its top.

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

[0014] 1. In this invention, when molten metal fragments with sparks generated from cutting metal are sucked into the air inlet box, the high-speed airflow causes the molten fragments to impact the ramp inside the air inlet box, breaking up large molten fragments. Then, small molten fragments continue to impact and break down into even smaller particles through the impact crushing mechanism. Combined with the airflow generated during air intake, the small fragments after impact are cooled and extinguished. Therefore, after entering the dust collector box, they will not cause a fire caused by flammable materials, resulting in high safety.

[0015] 2. The small molten debris formed after impacting the inclined plane inside the air inlet box flows sequentially through impact plates A, B, and C, forming three impact processes. This process can gradually pulverize and refine the molten debris and sparks until they are cooled and extinguished, resulting in better performance. In addition, impact plates A, B, and C are arranged in an array along the width of the air inlet box and extend vertically, ensuring that the impact coverage is sufficient to cover the entire area inside the air inlet box, thus improving the capture effect of molten debris and sparks.

[0016] 3. This utility model uses a drive mechanism to periodically operate and drive the scraping sleeve assembly to move up and down, thereby causing the frame-shaped scraping sleeve to slide up and down along each impact plate. This can scrape off the impurities and flammable materials accumulated and attached to each impact plate. The scraped impurities and flammable materials are then sucked into the dust collector housing, thus preventing fires caused by excessive accumulation of impurities and flammable materials on the impact plates when they encounter molten sparks and debris. This further improves the safety of this dust collector. Attached Figure Description

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.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to 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 embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-6 The present invention provides a dust collector for laser cutting, including a dust collector housing 1. An air inlet 2 is provided on the side of the dust collector housing 1. The air inlet 2 consists of an air inlet box 21 and an air inlet 22. The air inlet box 21 is arranged in a communicating manner on the side of the dust collector housing 1, and the air inlet 22 is arranged in a communicating manner at the bottom of the air inlet box 21. The air inlet box 21 is sloped towards one side of the dust collector housing 1 at the position above the air inlet 22. An impact fragmentation mechanism 3 is provided in the air inlet box 21. The impact fragmentation mechanism 3 is used to impact and fragment the molten sparks until they are extinguished.

[0028] When this dust collector for laser cutting is in operation, the impeller arranged inside the dust collector housing 1 generates negative pressure, which draws dust and smoke from the air inlet 22 into the air inlet box 21, and then flows from the air inlet box 21 into the dust collector housing 1. The dust and smoke in the air are filtered by the filter cartridge. The dust collector housing 1 adopts existing technology, and the specific structure and working principle of the dust collector housing 1 will not be described in detail.

[0029] Molten shavings with sparks generated from cutting metal are sucked into the air inlet box 21. The high-speed airflow causes the molten shavings to impact the ramp inside the air inlet box 21, breaking up large molten shavings. Then, the smaller molten shavings are further impacted into smaller particles by the impact crushing mechanism 3. Combined with the airflow generated during air intake, the small particles are cooled and extinguished after impact. Therefore, after entering the dust collector housing 1, they will not cause a fire caused by flammable materials, ensuring high safety.

[0030] Specifically, the impact fragmentation mechanism 3 includes several impact plates A31, several impact plates B32 and several impact plates C33. Several impact plates A31 are arranged in an array in the air inlet box 21 along the width direction and are located downstream of the air inlet 22. Several impact plates B32 are arranged in an array in the air inlet box 21 along the width direction and are located downstream of the impact plates A31. Several impact plates C33 are arranged in an array in the air inlet box 21 along the width direction and are located downstream of the impact plates B32. Impact plates A31, B32 and C33 all extend vertically.

[0031] The small molten debris formed after impacting the inclined slope inside the air inlet box 21 flows sequentially through impact plates A31, B32, and C33, forming three impact processes. This process can gradually pulverize and refine the molten sparks and debris until they cool and extinguish, resulting in better performance. In addition, impact plates A31, B32, and C33 are arranged in an array along the width of the air inlet box 21 and extend vertically, ensuring that the impact coverage is sufficient to cover the entire area inside the air inlet box 21, thus improving the capture effect of molten sparks and debris.

[0032] An inlet gap A311 is formed between two adjacent impact plates A31. Each impact plate B32 corresponds to each inlet gap A311. An inlet gap B321 is formed between two adjacent impact plates B32. An impact plate C33 corresponds to each inlet gap B321. An inlet gap C331 is formed between two adjacent impact plates C33. After the molten sparks and debris impact the impact plate A31, they flow downstream through the inlet gap A311. Then they impact the impact plate B32 and flow downstream through the inlet gap B321. Then they impact the impact plate C33 and finally flow downstream through the inlet gap C331 into the dust collector housing 1, thus achieving a three-impact effect.

[0033] During long-term operation, flammable materials present in the air can easily accumulate on impact plates A31, B32, and C33. This can easily cause a fire when molten, sparking debris comes into contact with these flammable materials. To address this problem, the present invention makes the following improvements:

[0034] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, frame-shaped scraping sleeves 41 are slidably fitted on impact plates A31, B32, and C33. The frame-shaped scraping sleeves 41 are connected to each other by corresponding connecting arms 42 to form a scraping sleeve assembly 4. The air inlet box 21 is equipped with a drive mechanism 5 for adjusting the lifting and lowering of the scraping sleeve assembly 4. The drive mechanism 5 periodically drives the scraping sleeve assembly 4 to move up and down, thereby causing the frame-shaped scraping sleeves 41 to slide up and down along each impact plate. This can scrape off the impurities and flammable materials accumulated on each impact plate. The scraped impurities and flammable materials are sucked into the dust collector housing 1, thereby preventing fires caused by excessive accumulation of impurities and flammable materials on the impact plates when they encounter molten sparks and debris, further improving the safety of this dust collector.

[0035] Specifically, the drive mechanism 5 includes a mounting base 51, an electric push cylinder 52, and a connector 53. The electric push cylinder 52 is vertically fixed to the top of the air inlet box 21 via the mounting base 51. The telescopic rod 521 of the electric push cylinder 52 extends through into the air inlet box 21. The connector 53 is fixed to the end of the telescopic rod 521. The connector 53 is fixedly connected to two of the connecting arms 42. Through the telescopic operation of the electric push cylinder 52, the telescopic rod 521 can drive the entire scraping sleeve 4 to rise and fall synchronously under the connection of the connector 53, thereby driving each frame-type scraping sleeve 41 to scrape and clean each impact plate.

[0036] Specifically, the air inlet box 21 is fixedly connected to the side of the dust collector housing 1 via a flange A211 located on its side. The flange A211 is fastened to the side of the dust collector housing 1 with bolts to realize the installation of the air inlet box 21. The air inlet 22 is fixedly connected to the bottom of the air inlet box 21 via a flange B221 located on its top. The flange B221 is fastened to the bottom of the air inlet box 21 with bolts to realize the installation of the air inlet 22. At the same time, this installation method makes the air inlet box 21 and the air inlet 22 detachable, which facilitates internal inspection and maintenance and cleaning when blocked.

[0037] 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.
