Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a waste cutting dust treatment and waste recycling system. Background Technology

[0002] In industrial production, the processing of various raw materials such as metals, plastics, and stone generates a large amount of waste. This waste usually needs to be processed by laser cutting equipment. Laser cutting, with its advantages of high precision and high cutting efficiency, has become the mainstream method for the refined treatment of waste. However, the dust and debris generated during its operation are particularly prominent, seriously restricting the optimization of the production environment and the improvement of operational safety. The specific technical pain points are as follows: First, laser cutting dust has unique characteristics, making efficient dust control difficult with existing methods. Laser cutting instantly melts or vaporizes waste materials using a high-energy beam, generating not only conventional dust particles but also high-temperature molten micro-dust (such as micron-sized metal oxide dust from cutting metal scrap and toxic polymeric fumes from cutting plastic scrap). These dust particles are finer, diffuse faster, and some high-temperature dust easily adheres to equipment surfaces, forming stubborn deposits. Long-term exposure to laser cutting dust not only increases the risk of pneumoconiosis for workers but can also lead to more serious health problems such as respiratory allergies and pulmonary fibrosis from inhaling toxic polymeric dust.

[0003] Secondly, the unique shape of laser cutting waste makes existing recycling solutions poorly adaptable and prone to secondary pollution. Laser cutting waste falls into two categories: spherical or flocculent fine chips formed after molten material cools, and incompletely vaporized lumpy waste. Existing recycling devices mostly place the waste directly on the ground and rely on manual operation to transfer it from the ground to collection containers. This process is not only labor-intensive and inefficient, but also prone to spillage due to human error.

[0004] In summary, the current waste cutting field urgently needs an integrated processing system that can enable the coordinated movement of dust collection and recycling components, effectively control dust pollution, and improve the automation and efficiency of waste recycling. This system would solve the technical problems of incomplete dust collection, cumbersome waste recycling processes, and poor equipment coordination in existing technologies, and meet the industrial production demand for green, environmentally friendly, and efficient operations. Summary of the Invention

[0005] The purpose of this invention is to address the deficiencies in the existing technology by proposing a waste cutting dust treatment and waste recycling system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A waste cutting dust treatment and waste recycling system, characterized in that it includes a positioning frame, on which a recycling component is provided, and the recycling component is movably mounted on the positioning frame. The recycling assembly includes a collection hopper, the side wall of which is provided with at least one set of suction ports; the side wall of the collection hopper is provided with an opening, the opening is provided with an opening and closing plate, and a push plate is provided on the side opposite to the opening, the push plate is driven by a drive box, and the push plate is located below the suction ports.

[0007] Furthermore, the positioning frame includes an outer frame, an X-axis translation component, a crossbar, and a Y-axis translation component; the X-axis translation component consists of two sets, which are slidably mounted on the outer frame; the crossbar is fixedly connected between the two X-axis translation components; the Y-axis translation component is slidably mounted on the crossbar; and the retraction component is located on top of the Y-axis translation component.

[0008] Furthermore, the collection hopper includes a rectangular hopper and a flared plate. The suction port is in two sets, symmetrically arranged on the left and right side walls of the rectangular hopper. The opening is located on the front side wall of the rectangular hopper and is the same width as the front side wall. The push plate is slidably connected between the left and right side walls of the rectangular hopper. The drive box is located on the rear side wall of the rectangular hopper.

[0009] Furthermore, a dust box is provided at the dust suction port. The dust box includes an upper box and a lower box, which are connected. A negative pressure component is provided on the side wall of the upper box, and a spray pipe is provided on the top of the upper box. The spray pipe is located above the position where the upper box and the lower box are connected.

[0010] Furthermore, the spray pipe is configured as a plate-shaped structure and is located between the dust suction port and the air intake port of the negative pressure component. The height of the spray pipe is lower than the height of the dust suction port and the air intake port.

[0011] Furthermore, a waste bin is provided at the bottom of the collection hopper, and the waste bin is connected to the collection hopper through a side box. A guide plate is provided inside the side box, and the guide plate is used to guide the waste falling from the opening into the waste bin.

[0012] Furthermore, a vibration motor is installed between the waste bin and the collection hopper.

[0013] Furthermore, a drive rod is provided on the drive box, which penetrates the side wall of the collection hopper and extends inward, and the extended end of the drive rod is connected to the push plate.

[0014] Beneficial effects

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the design of the present invention, an integrated processing system is proposed that can realize the coordinated movement of the dust collection component and the recycling component, effectively control dust pollution, and improve the automation and efficiency of waste recycling. This solves the technical problems in the prior art such as incomplete dust collection, cumbersome waste recycling process, and poor equipment coordination, and meets the needs of industrial production for green, environmentally friendly, and efficient operation.

[0017] The design of the dust suction port located above the push plate can continuously absorb the residual dust raised during the movement of waste materials by the push plate, effectively solving the problem of secondary dust generation during the waste material transfer stage of existing equipment. In addition, the location of the dust suction port above the push plate can also ensure that waste debris can fall smoothly into the collection hopper, avoiding blockage of the dust suction port.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] In the description of this invention, 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 this invention 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 this invention.

[0024] Reference Figure 1 - Figure 5 A waste cutting dust treatment and waste recycling system includes a positioning frame, a recycling component is provided on the positioning frame, and the recycling component is movably mounted on the positioning frame. The recycling assembly includes a collection hopper, the side wall of which is provided with at least one set of suction ports 3; the side wall of the collection hopper is provided with an opening, an opening and closing plate 2 is provided at the opening, and a push plate is provided on the side opposite the opening, the push plate is driven by a drive box, and the push plate is located below the suction ports 3.

[0025] The recycling assembly can move on the positioning frame, and the collection bucket can adjust its position synchronously with the collection bucket. It can flexibly follow the different areas of the waste cutting (such as segmented cutting of long strip waste and multi-angle cutting of irregular waste).

[0026] The dust suction port 3, located on the side wall of the collection hopper, can directly target the core area where dust is generated during waste cutting (such as below the contact point between the cutting blade and the waste), absorbing dust from the source with negative pressure to prevent dust from spreading into the working environment. Simultaneously, the collection hopper itself forms a physical barrier against flying dust generated during cutting, reducing dust overflow. Furthermore, the design of the dust suction port 3 above the push plate allows for continuous absorption of residual dust stirred up during waste movement, effectively solving the secondary dust problem in existing equipment during waste transfer. Moreover, the location of the dust suction port 3 above the push plate ensures that waste debris falls smoothly into the collection hopper, preventing blockage of the dust suction port 3.

[0027] The push plate inside the collection hopper, driven by the drive box, can automatically push the waste material towards the opening after the waste material is cut. The opening and opening / closing plate 2 structure on the side wall of the collection hopper can precisely control the opening and closing when the push plate pushes the waste material, so as to achieve the cleaning and collection of debris inside the collection hopper.

[0028] In other preferred embodiments, the positioning frame includes an outer frame, an X-axis translation component, a crossbar, and a Y-axis translation component; there are two sets of X-axis translation components, which are slidably disposed on the outer frame, the crossbar is fixedly connected between the two X-axis translation components, the Y-axis translation component is slidably disposed on the crossbar, and the retraction component is disposed on the top of the Y-axis translation component.

[0029] Two sets of X-axis translation components can slide stably along the outer frame, driving the crossbar and the Y-axis translation and retrieval components on the crossbar to move laterally (in the X-axis direction). The Y-axis translation component can slide along the crossbar, driving the retrieval component to move precisely longitudinally (in the Y-axis direction). When the laser cutting head adjusts its cutting position longitudinally, the X-axis and Y-axis translation components can simultaneously drive the collection bucket to respond quickly.

[0030] In other preferred embodiments, the collection hopper includes a rectangular hopper and a flared plate. The suction port 3 is in two sets, symmetrically arranged on the left and right side walls of the rectangular hopper. The opening is located on the front side wall of the rectangular hopper and is the same width as the front side wall. The push plate is slidably connected between the left and right side walls of the rectangular hopper, and the drive box is arranged on the rear side wall of the rectangular hopper.

[0031] In other preferred embodiments, a dust box 4 is provided at the suction port 3. The dust box 4 includes an upper box and a lower box 10, which are connected. A negative pressure component 8 is provided on the side wall of the upper box, and a spray pipe 9 is provided on the top of the upper box. The spray pipe 9 is located above the position where the upper box and the lower box 10 are connected.

[0032] The negative pressure component 8 on the side wall of the upper chamber can quickly form a stable negative pressure environment inside the dust box 4. This negative pressure can form a directional airflow to the cutting area through the dust suction port 3, which can efficiently suck the fine dust (such as metal oxide dust and polymer smoke) generated by laser cutting into the dust box 4, and prevent the dust from spreading near the dust suction port 3.

[0033] The spray pipe 9 at the top of the upper chamber is located above the connection between the upper and lower chambers 10, and can accurately spray atomized liquid (such as water or environmentally friendly dust suppressant) into the chamber. When the dust-laden airflow enters the upper chamber from above, the atomized droplets sprayed from the spray pipe 9 can fully contact the dust particles, causing the fine dust to quickly agglomerate into larger particles. These particles fall into the lower chamber 10 along with the liquid under the action of gravity.

[0034] Specifically, the spray pipe 9 is configured as a plate-shaped structure and is located between the dust suction port 3 and the air intake port of the negative pressure component 8. The height of the spray pipe 9 is lower than the height of the dust suction port 3 and the air intake port.

[0035] The plate-shaped spray pipes 9 are horizontally distributed between the dust suction port 3 and the air intake of the negative pressure component 8, forming an "airflow interception barrier". When the dust-laden airflow enters the upper chamber from the dust suction port 3, because the height of the spray pipes 9 is lower than that of the dust suction port 3 and the air intake, the airflow cannot flow directly from the dust suction port 3 to the air intake. It must detour around both sides of the plate-shaped spray pipes 9 or pass through the spray area on the plate structure. This path design forces the dust-laden airflow to pass through the coverage area of ​​the atomized liquid, preventing dust from being sucked away by the negative pressure component 8 before contacting the atomized liquid, greatly increasing the contact probability between dust and atomized liquid droplets, and ensuring that fine dust can be fully captured.

[0036] 6. A waste cutting dust treatment and waste recycling system according to claim 1, characterized in that a waste bin 1 is provided at the bottom of the collection hopper, the waste bin 1 is connected to the collection hopper through a side box 6, and a guide plate 7 is provided inside the side box 6, the guide plate 7 being used to guide the waste falling from the opening into the waste bin 1. When the push plate pushes the waste chips in the collection hopper toward the opening, the waste chips fall from the opening into the side box 6, and the guide plate 7 in the side box 6 provides a clear guiding path for the falling waste chips through an inclined angle or curved surface design.

[0037] 7. A waste cutting dust treatment and waste recycling system according to claim 6, characterized in that a vibrating motor is provided between the waste bin 1 and the collection hopper.

[0038] Some waste chips generated by laser cutting (such as fine metal molten chips and plastic high-temperature adhered fragments) tend to adhere and accumulate on the surface of the guide plate 7, the inner wall of the side box 6, and the edge of the collection hopper opening. When the vibration motor is working, it can transmit vibration energy to the connection between the bottom of the collection hopper and the side box 6, and break up the adhered waste chip clumps through high-frequency micro-vibration to prevent waste chips from adhering to the collection hopper; at the same time, it can also act on the waste bin 1 to prevent local accumulation of waste chips in the waste bin 1.

[0039] 8. A waste cutting dust treatment and waste recycling system according to claim 1, characterized in that a drive rod 5 is provided on the drive box, the drive rod 5 penetrates the side wall of the collection hopper and extends inward, and the extended end of the drive rod 5 is connected to the push plate. A drive wheel is provided inside the drive box, and the drive rod 5 meshes with the drive wheel. When the drive wheel rotates, it can drive the drive rod 5 to move horizontally, thereby driving the push plate to achieve the purpose of pushing materials.
