Description

Technical Field

[0001] The present application relates to the technical field of sanding machine equipment, and in particular to a dust cover. Background Art

[0002] Sanders, also known as grinding wheels, are often used to sharpen various cutting tools, as well as perform surface cleaning tasks such as grinding and deburring parts.

[0003] The applicant has a prior patent application with application number CN202410343709.5, which discloses a sanding frame device with a self-rotating and revolving brush roller, which overcomes the problem that traditional sanding machines can only grind the plate in a single direction forward or backward, but cannot grind the steps or side edges of the plate.

[0004] When the above-mentioned sanding machine is in use, the grinding wheel grinds the plate, which will generate a large amount of dust. This dust will be blown into the air, which will not only pollute the air environment, but also cause respiratory infections and other diseases to the operators. Utility Model Content

[0005] In order to reduce the harm caused by the sanding machine to the surrounding environment and personnel when in use, the present application provides a dust cover.

[0006] The present application provides a dust cover, which adopts the following technical solution:

[0007] A dust cover comprises a sand rack, a collection box, a first dust collection assembly and a second dust collection assembly; the sand rack fixed cover is arranged on a sanding machine; the collection box is fixedly arranged on the sand rack; the first dust collection assembly is arranged on the sand rack and is used to transport dust generated on both sides of the sanding machine in the length direction into the collection box; the second dust collection assembly is arranged on the sand rack and is used to transport dust generated on both sides of the sanding machine in the width direction into the collection box.

[0008] By adopting the above technical solution, when the sander is in use, the first dust collection component and the second dust collection component are both in working state. The first dust collection component transports the dust generated on both sides of the sander in the length direction to the collection box, and the second dust collection component transports the dust generated on both sides of the sander in the width direction to the collection box, thereby reducing the dust dispersed in the surrounding environment during the use of the sander and reducing the harm to the surrounding environment and personnel.

[0009] Optionally, the first dust suction component is provided with two groups, and is respectively located on both sides of the length direction of the sander, and the first dust suction component includes a first dust suction hopper and a first dust suction pipe; the first dust suction hopper is fixedly set on the sand frame; the two ends of the first dust suction pipe are respectively connected to the interior of the first dust suction hopper and the interior of the collection box; the collection box is provided with an exhaust component, and the exhaust component is arranged on the collection box and is used to discharge the air in the collection box.

[0010] By adopting the above technical solution, when the sander is in use, the exhaust component is used to discharge the air in the collection box, forming a negative pressure in the collection box. Under the action of the negative pressure, part of the dust generated by the sander enters the collection box through the first dust suction hopper and the second dust suction pipe, thereby realizing the transportation of the dust generated on both sides of the length direction of the sander into the collection box.

[0011] Optionally, the second dust suction assembly is provided in two groups, and is respectively located on both sides of the width direction of the sander, and the second dust suction assembly includes a second dust suction hopper, a second dust suction pipe and an arc-shaped baffle; the second dust suction hopper is fixedly provided on the sand rack; the two ends of the second dust suction pipe are respectively connected to the interior of the second dust suction hopper and the interior of the collection box; the arc-shaped baffle is fixedly provided on the sand rack, and the arc-shaped baffle is used to divert the dust generated by the sander so that it flows into the interior of the second dust suction hopper.

[0012] By adopting the above technical solution, when the sander is in use, under the action of the negative pressure in the collection box, another part of the dust generated by the sander diffuses in the width direction of the sander. Under the guidance of the arc baffle, it enters the collection box through the second dust suction hopper and the second dust suction pipe, thereby realizing the transportation of the dust generated on both sides of the width direction of the sander into the collection box.

[0013] Optionally, an exhaust pipe is provided at the top of the collection box; the exhaust assembly includes a fan, which is fixedly provided on the exhaust pipe and is used to discharge the air in the collection box through the exhaust pipe.

[0014] By adopting the above technical solution, when the sanding machine is working, the fan is in a working state, and the air in the collection box is discharged through the exhaust pipe by the fan, thereby forming a negative pressure inside the collection box.

The filter plate divides the interior of the collection box into a first box body and a second box body. The exhaust pipe is connected to the first box body, and the first dust suction pipe and the second dust suction pipe are both connected to the second box body.

[0016] By adopting the above technical solution, the dust generated by the sander is blocked by the filter plate and stays in the second box after entering the collection box. On the one hand, it prevents the dust from flowing out through the exhaust pipe and spreading in the surrounding environment, and on the other hand, it prevents the dust from damaging the fan.

[0017] Optionally, a cleaning port is provided on the collection box, and the cleaning port is connected to the second box body; a cleaning door is slidably provided at the cleaning port; a fixing component is provided on the collection box, and the fixing component is used to fix the cleaning door and the collection box.

[0018] By adopting the above technical solution, when a certain amount of dust accumulates in the collection box, the operator first cancels the fixation of the cleaning door and the collection box through the fixing assembly, and then slides the cleaning door away from the cleaning port. At this time, the operator can discharge the dust in the collection box through the cleaning port, and then the operator slides the cleaning door so that it is located at the opening of the cleaning port, and finally uses the fixing assembly to fix the cleaning door and the collection box, so as to prevent the cleaning door from being accidentally touched away from the cleaning port during use of the sander, so that the dust in the collection box flows into the surrounding environment through the cleaning port.

[0019] Optionally, two guide rails are fixedly provided on the collection box, and the two guide rails are respectively located on both sides of the cleaning port, and a sliding groove is provided on the side where the two guide rails are close to each other; the cleaning door is slidably provided in the sliding groove.

[0020] By adopting the above technical solution, the guide rail is used to limit the cleaning door, so that the cleaning door can be slidably arranged on the collection box.

[0021] Optionally, the fixing component includes a first magnetic strip and a second magnetic strip; the first magnetic strip is fixedly arranged on the collection box, and the second magnetic strip is fixedly arranged on the cleaning door, and there is a mutual attraction between the first magnetic strip and the second magnetic strip.

[0022] By adopting the above technical solution, the mutual attraction between the first magnetic strip and the second magnetic strip is utilized to achieve the fixation of the cleaning door and the collection box.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0045] The implementation principle of a dust cover in the embodiment of the present application is as follows:

[0046] When the sander is in use, the fan 31 is in operation. Under the action of the fan 31, the air in the collection box 2 is discharged through the exhaust pipe 21, creating a negative pressure in the collection box 2. Under the action of the negative pressure in the collection box 2, the dust generated by the sander located on both sides of the sander in the longitudinal direction will enter the first dust hopper 41, and then enter the collection box 2 through the first dust suction pipe 42. Meanwhile, the dust generated by the sander located on both sides of the sander in the width direction will enter the second dust hopper 51 under the guidance of the arc-shaped baffle 53, and then enter the collection box 2 through the second dust suction pipe 52. The dust entering the collection box 2 is retained in the second box body 23 by the action of the filter plate 32.

[0047] When the sander has been used for a period of time and a certain amount of dust has accumulated in the collection box 2, the operator pulls the cleaning door 25 to make the cleaning door 25 slide relative to the guide rail 26 along the slide groove 261 and away from the cleaning port 24. At this time, the operator cleans the dust in the collection box 2. After cleaning, the operator pushes the cleaning door 25 to slide in the opposite direction so that the cleaning door 25 is located at the opening of the cleaning port 24. At this time, the first magnetic strip 61 and the second magnetic strip 62 are arranged opposite to each other. Under the mutual attraction between the first magnetic strip 61 and the second magnetic strip 62, the cleaning door 25 is fixed to the collection box 2.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
