Description

Technical Field

[0001] This utility model relates to the field of sanding machine technology, and in particular to a sanding machine dust recovery structure. Background Technology

[0002] A sander is a type of mechanical equipment mainly used to grind and polish the surfaces of various materials to achieve a smooth and flat finish. A wide belt sander is a type of sander that uses sandpaper, abrasive wheels, or other abrasive tools to rub against the material surface, removing small particles or protrusions and thus improving the surface finish and roughness.

[0003] Wide belt sanders generate a large amount of dust during operation. To improve the working environment, workers connect the suction pipe of an external professional dust collection device to the dust collection assembly installed on the top of the wide belt sander. During connection, workers simply slip the suction pipe onto the interface of the dust collection assembly. This connection method mainly relies on the friction between the suction pipe and the interface to maintain the connection. During the operation of the belt sander, due to the vibration of the equipment, the suction pipe is easily loosened and eventually falls off, which will affect the normal dust collection operation. Therefore, we propose a dust recovery structure for sanders to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dust recovery structure for sanders.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

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

[0023] Reference Figure 1-5 A dust recovery structure for a sander includes a sander body 1, a dust collection hood 2 installed at the end of the sander body 1, an interface 3 inserted inside the dust collection hood 2, a dust collection pipe 4 sleeved on the outside of the interface 3, a connecting plate 5 connected to the side of the dust collection hood 2, a fixing plate 6 connected to the top of the connecting plate 5, a movable plate 7 above the fixing plate 6, and a connecting block 8 connected to the end of the movable plate 7. One set of connecting blocks 8 has a threaded groove inside, and a threaded rod 9 is inserted inside the threaded groove. The bottom end of the threaded rod 9 is connected to the connecting plate 5 through a bearing. Through the threaded engagement of the connecting block 8 and the threaded rod 9, the movable plate 7 can be driven to move up and down, thereby limiting and fixing the dust collection pipe 4.

[0024] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the fixed plate 6 and the movable plate 7 are respectively glued with rubber sleeves 11 on the side that are close to each other, and the other end of the rubber sleeve 11 is tightly attached to the outer wall of the suction pipe 4. The rubber sleeve 11 made of rubber material can effectively increase the friction when the movable plate 7 contacts the suction pipe 4, thereby effectively ensuring the limiting effect of the suction pipe 4.

[0025] Furthermore, refer to Figure 3 It can be seen that the other set of connecting blocks 8 has an insertion slot inside, and a connecting post 10 is inserted inside the insertion slot. The bottom end of the connecting post 10 is fixedly connected to the connecting plate 5. In use, the guiding operation of the movable plate 7 can be realized through the cooperation of the insertion slot and the connecting post 10.

[0026] Furthermore, refer to Figure 3 It can be seen that the connecting plate 5 is symmetrically inserted with support plates 12, and filter screens 13 are distributed above the support plates 12. The filter screens 13 are inserted inside the interface 3. Through the filter screens 13 inserted inside the interface 3, the blocking operation of large-diameter impurities can be achieved.

[0027] Furthermore, refer to Figure 4 and Figure 5 It can be seen that the support plate 12 is set as an L-shaped structure, and the end of the support plate 12 is provided with a hole. The inner wall of the hole is connected to a spring 15, and the other end of the spring 15 is connected to the cover plate 17. The inner side of the cover plate 17 is connected to a positioning block 14. The inside of the connecting plate 5 is provided with a limiting groove that matches the positioning block 14. In use, the support plate 12 and the filter screen 13 can be disassembled by the cooperation of the cover plate 17 and the positioning block 14, so that large-diameter debris inside the dust hood 2 and the interface 3 can fall off due to gravity.

[0028] Furthermore, refer to Figure 5 It can be seen that the inner side of the filter screen 13 is connected to the crossbar 16, and the inside of the support plate 12 is provided with a moving groove that matches the crossbar 16. Through the cooperation of the crossbar 16 and the moving groove, the cover plate 17 can be guided laterally, thereby ensuring the stability of the cover plate 17 when it is pulled laterally.

[0029] Furthermore, refer to Figure 4 It can be seen that the top of the support plate 12 and the bottom of the filter screen 13 are set in an L-shape. The top of the support plate 12 and the bottom of the filter screen 13 are connected by bolts. With the L-shaped structure of the support plate 12 and the filter screen 13, and the bolts, it is easy for the staff to disassemble and replace the filter screen 13 and the support plate 12 when they reach the end of their service life.

[0030] Working Principle: When using this invention, the operator first places the device in a suitable position, then places the suction pipe 4, connected to an external vacuum cleaner, over the interface 3. After placement, the operator rotates the threaded rod 9, causing the connecting block 8 to engage with it, bringing the movable plate 7 and the fixed plate 6 closer together and limiting and fixing the suction pipe 4. The workpiece to be sanded is then placed on the sander body 1 and comes into contact with the sandpaper for processing. During processing, the external vacuum cleaner draws the dust generated into the dust hood 2, which is then transported through the interface 3 and the suction pipe 4 to the... The dust is recycled within the vacuum equipment. During the dust recycling process, the filter screen 13 inserted inside the interface 3 can block large-sized debris to ensure the flow of the vacuum pipe 4. After recycling, the operator can rotate the threaded rod 9 in the opposite direction and then pull the vacuum pipe 4 out from the outside of the interface 3. Then, by pulling the cover plate 17 horizontally, the positioning block 14 is pulled out from the inside of the connecting plate 5. At this time, the operator can pull the filter screen 13 vertically to pull it out from the inside of the interface 3. Since the interface 3 is designed with an inclined structure, large-sized debris inside the interface 3 can fall down. The above is the entire working principle of this utility model.
