Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically to a multi-directional dust removal belt grinding machine. Background Technology

[0002] A belt sander is a surface treatment device that uses a ring-shaped abrasive belt as the grinding tool. Driven by a motor, the belt rotates at high speed to perform rough grinding, trimming, deburring, and polishing on workpieces made of metal, wood, and composite materials. Belt sanding of metals generates metal dust (such as iron, aluminum, and zinc), while sanding wood releases wood dust. On the one hand, inhaling metal dust can lead to pneumoconiosis and metal fume fever. On the other hand, hard particles in the dust can embed into the surface of the abrasive belt, accelerating abrasive passivation and shortening the belt's lifespan.

[0003] For example, patent application publication number CN110814976A discloses a grinding wheel machine with high-speed dust removal function. The grinding wheel machine includes a grinding wheel assembly, a primary filtration dust removal box, and a secondary filtration dust removal box. The grinding wheel assembly includes a grinding wheel and a main motor. The primary filtration dust removal box is located behind the grinding wheel, with an inlet on its front side, a fine filter screen inside, and an outlet at the bottom outside. A fan is installed on the rear side of the primary filtration dust removal box. The fan's inlet is connected to the inner cavity of the primary filtration dust removal box, and its outlet is connected to the inner cavity of the secondary filtration dust removal box. A high-precision filter cartridge and a pulse dust removal device are installed inside the secondary filtration dust removal box.

[0004] The advantages of the aforementioned grinding wheel machine lie in its combination of a primary filtration dust collection box and a secondary filtration dust collection box, which effectively removes large and fine dust particles respectively, thus improving dust removal efficiency. However, it still has some shortcomings: the aforementioned grinding wheel machine has only one dust inlet. Dust enters from one dust inlet and then passes through multiple filtration stages. While this can improve the dust removal effect, when there are many dust particles, one dust inlet is obviously insufficient to meet the usage requirements. At this time, it is necessary to quickly remove the dust and achieve dust-free processing at the grinding site as quickly as possible. Therefore, the existing dust removal methods of grinding wheel machines cannot meet the actual production needs. Utility Model Content

[0005] This invention provides a multi-directional dust removal belt sander to solve the technical problem that existing belt sanders cannot quickly remove dust from the sanding site.

[0006] To solve the above problems, the multi-directional dust removal belt sander provided by this utility model adopts the following technical solution:

[0007] A multi-directional dust removal belt sander includes a loading platform, a robotic arm, and a frame. A sanding belt is rotatably arranged on the frame. The robotic arm is used to move workpieces from the loading platform to the location of the sanding belt for sanding. The machine also includes: The bottom settling assembly, located at the bottom of the frame, includes multiple outlets for spraying high-speed water jets to form a water curtain to adsorb and settle large dust particles. The upper air outlet is located on the upper side and / or side of the frame. The air outlet is connected to a fan and is used to quickly adsorb small dust particles.

[0008] The beneficial effects of the multi-directional dust removal belt sander provided by this utility model are as follows: by using both water curtain adsorption and air outlet adsorption, it not only achieves multi-directional dust absorption, but also absorbs and processes small and large dust particles separately from the top and bottom, enabling the orderly and rapid extraction of dust from the sanding site. Compared with the prior art which only has one dust inlet, this application effectively solves the technical problem that the existing belt sander cannot quickly remove dust from the sanding site.

[0009] Furthermore, a dust collection box is arranged beside the frame, and the fan is arranged inside the dust collection box. The fan is connected to the air outlet. The dust collection box also has a reflux structure, a filter structure, and a water inlet pipe. The reflux structure is used to extract the mixture after the water has settled the dust, the filter structure is used to filter the dust, and the water inlet pipe is used to pump the filtered water back into the bottom settling assembly. The mixture is refluxed and filtered to obtain relatively pure water, which is then recycled for dust settling.

[0010] Furthermore, there are two air outlets: a top air outlet and a side air outlet. The top air outlet is connected to the fan via an air outlet duct. The outlet of the air outlet duct is located beside the side air outlet, so as to create negative pressure through high-speed airflow to achieve dust adsorption at the side air outlet. One fan provides adsorption power for both air outlets, improving the fan utilization rate and reducing cost.

[0011] Furthermore, the dust collector has a settling trough located below the air outlet duct, and the dust collector is connected to the bottom settling assembly to absorb the mixed liquid. The dust collector also has a baffle opposite to the side air outlet to further ensure that negative pressure is formed at the side air outlet.

[0012] Furthermore, the bottom settling assembly includes a bottom trough, a water outlet pipe is arranged in the bottom trough, and multiple water outlets are opened on the water outlet pipe. The bottom trough has a water outlet inclined plate that connects to the settling trough, and the water outlet inclined plate constitutes a water outlet structure.

[0013] Furthermore, each outlet is arranged facing the inclined outlet plate to ensure the smooth flow of the mixture.

[0014] Furthermore, there are two water outlet inclined plates, and two first filter buckets are arranged in the dust removal box, each located below the two water outlet inclined plates. The side of the first filter bucket has multiple water passage holes so that water flows into the settling tank.

[0015] Furthermore, a clean water hopper is arranged inside the settling tank, and a delivery pump is arranged in the clean water hopper. The delivery pump is connected to the outlet pipe through the inlet pipe. The clean water hopper has filter holes around its perimeter so that clean water can enter the clean water hopper from the settling tank. The first filter hopper and the filter holes constitute the filter structure.

[0016] Furthermore, the height of the inlet pipe is higher than that of the outlet ramp. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0021] An embodiment of the multi-directional dust removal belt grinder provided by this utility model: like Figures 1 to 7 As shown, the multi-directional dust removal belt sander includes a body 1, a feeding platform 2, a robot arm 3, and a frame 4. A sanding belt 5 is rotatably arranged on the frame 4. The robot arm 3 is used to move the workpiece from the feeding platform 2 to the position of the sanding belt 5 for sanding. Based on the above arrangement, the entire sander also includes a bottom settling component 6 and an upper air outlet.

[0022] The bottom settling assembly 6 is located at the bottom of the frame 4 and includes multiple water outlets 7 for spraying high-speed water jets. The high-speed water jets form a water curtain to adsorb and settle large dust particles. The upper air outlet is located on the upper side and / or side of the frame 4, and is connected to a fan 8. The air outlet is used to quickly adsorb small dust particles. Through the two methods of water curtain adsorption and air outlet adsorption, not only is dust absorption achieved from multiple directions, but small dust particles are also absorbed and processed from the top and bottom respectively, which can orderly and quickly extract dust from the grinding site.

[0023] Specifically, such as Figures 1 to 5 As shown, a dust collection box 9 is also arranged beside the frame 4. The dust collection box 9 houses the aforementioned fan 8, which is connected to the air outlet. The dust collection box 9 also includes a reflux structure, a filter structure, and a water inlet pipe 12. The reflux structure is used to extract the mixture after the water has settled the dust. The filter structure is used to filter the dust. The water inlet pipe 12 is used to pump the filtered water back into the bottom settling assembly 6. The mixture, after reflux filtration, yields relatively pure water, which is recycled for further dust settling.

[0024] like Figure 6 As shown, in this embodiment, there are two air outlets: a top air outlet 13 and a side air outlet 14. The top air outlet 13 is connected to the fan 8 via an air outlet duct 10. The outlet of the air outlet duct 10 is located beside the side air outlet 14, so as to create negative pressure through high-speed airflow to achieve dust adsorption at the side air outlet 14. One fan 8 provides adsorption power for both air outlets, improving the utilization rate of the fan 8 and reducing cost. In other embodiments, one fan 8 can be arranged for each of the two air outlets, or only one air outlet can be provided, located at the top or side.

[0025] like Figure 2 and Figure 3 As shown, the dust collector 9 has a settling trough 15 located below the air outlet 10. The dust collector 9 is connected to the bottom settling assembly 6 to absorb the mixed liquid. The dust collector 9 also has a baffle 17 opposite to the side air outlet 14 to further ensure that a negative pressure is formed at the side air outlet 14.

[0026] Regarding the water outlet structure. For example... Figures 3 to 6 As shown, the bottom settling assembly 6 includes a bottom trough 18, within which a water outlet pipe 19 is arranged. The water outlet pipe 19 has multiple water outlets 7. The bottom trough 18 has a water outlet ramp 20 connecting to the settling trough 15, forming a water outlet structure. Simultaneously, each water outlet 7 is arranged facing the water outlet ramp 20 to ensure the smooth flow of the mixture. In other embodiments, the water outlets 7 may not be arranged facing the water outlet ramp 20.

[0027] like Figure 3 and Figure 4 As shown, there are two water outlet inclined plates 20. The dust collector 9 contains two first filter buckets 21 located below the two water outlet inclined plates 20 respectively. The sides of the first filter buckets 21 have multiple water passage holes 22 to allow water to flow into the settling tank 15. In other embodiments, the number of water outlet inclined plates 20 can be adjusted according to actual needs; for example, it can be one or three.

[0028] like Figure 6 and Figure 7 As shown, a purified water hopper 23 is also arranged inside the settling tank 15. A delivery pump 24 is installed in the purified water hopper 23. The delivery pump 24 is connected to the outlet pipe 19 through the inlet pipe 12. The purified water hopper 23 has 25 around its perimeter to allow purified water to enter the purified water hopper 23 from the settling tank 15. The first filter hopper 21 and the 25 constitute the filtration structure. In this embodiment, the height of the inlet pipe 12 is higher than the outlet inclined plate 20.

[0029] The working principle of the multi-directional dust removal belt sander provided by this utility model is as follows: the robot arm 3 moves the workpiece from the loading platform 2 to the position of the sanding belt 5. After the sanding belt 5 is started, it grinds the workpiece. At the same time, the fan 8 and the conveying pump 24 start working. The particulate dust generated during the grinding process spreads to the side of the frame 4. The large particulate dust moves downward and settles under the adsorption of the high-speed water flow and enters the settling tank 15. The small particulate dust is adsorbed by the top air outlet 13 and the side air outlet 14 and also enters the settling tank 15. It is absorbed and settled by the water. After being filtered by the first filter bucket 21 and the clean water tank 23, a part of the clean water flows back to the bottom tank 18 through the water inlet pipe 12 for recycling.
