Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding equipment technology, specifically a grinding machine that facilitates waste recycling. Background Technology
[0002] Furniture manufacturing uses wood, metal, or composite materials as a base. Through a systematic process including material selection and preparation, structural cutting, precision assembly, surface treatment, and coating, it creates home furnishing products that combine functionality and aesthetics. The sanding process uses a professional sander with a rotating belt wheel or eccentric sanding disc to remove burrs left from cutting and fill gaps between board joints, thereby reducing the flatness of the substrate surface. At the same time, it provides a uniform base for subsequent painting or veneer application, ensuring that the furniture is both practical and beautiful.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology:
[0004] Most grinding machines on the market currently use an open grinding chamber structure, which causes metal dust and debris to fly around randomly with the airflow or get stuck in the gaps of the equipment. Over time, the accumulated waste needs to be cleaned manually, which not only prolongs the downtime for maintenance, but also makes it easy for residual debris to re-enter the processing area, thereby scratching the outer surface of the workpiece and reducing product quality. Utility Model Content
[0005] The purpose of this invention is to provide a grinding machine that facilitates waste recycling, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding machine for convenient waste recycling, comprising a shell, a top cover rotatably mounted on the top of the shell, a collection groove slidably mounted inside the shell, a suction device fixedly mounted at the rear end of the shell, the shell comprising a first frame, a bracket fixedly mounted on the inner wall of the first frame, a first motor fixedly mounted on the top of the bracket, a first rotating shaft rotatably mounted on one end of the first motor, a grinding wheel fixedly mounted on one end of the first rotating shaft, a hinge fixedly mounted on the top of the first frame, a second frame fixedly mounted on the outer surface of the hinge, an air inlet on both sides of the second frame, a third frame slidably mounted inside the first frame, an air intake at one end of the third frame, a first screen fixedly mounted on the inner wall of the third frame, a second screen fixedly mounted on the bottom of the first screen, a fourth frame fixedly mounted at the rear end of the first frame, three support rods fixedly mounted on the inner wall of the fourth frame, a second motor fixedly mounted on one end of each support rod, a second rotating shaft rotatably mounted on one end of each second motor, and a fan blade fixedly mounted on one end of the second rotating shaft.
[0007] More preferably, a fixed base plate is fixedly installed on the inner wall of the first frame, and two operating ports are opened on the side end of the first frame.
[0008] More preferably, an observation window is provided at the top of the second frame.
[0009] More preferably, a third screen is fixedly installed at the bottom of the second screen.
[0010] More preferably, a handle is fixedly installed on the side end of the air intake.
[0011] More preferably, a filter screen is fixedly installed at the front end of the fourth frame.
[0012] More preferably, a baffle is fixedly installed at the rear end of the fourth frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This sander uses a support rod, a second rotating shaft, and fan blades to create negative pressure. Through various screens, it collects metal dust and wood chips generated during the furniture sanding process into a collection tank for unified recycling and reuse. This reduces the difficulty of manual processing and the maintenance time of the equipment, while also preventing the chips or metal dust generated during sanding from scratching the outer surface of the furniture.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a grinding machine for convenient waste recycling, including a shell 1, a top cover 2 rotatably mounted on the top of the shell 1, a collection groove 3 slidably mounted inside the shell 1, and a suction device 4 fixedly mounted at the rear end of the shell 1. The shell 1 includes a first frame 11, a bracket 12 fixedly mounted on the inner wall of the first frame 11, a first motor 13 fixedly mounted on the top of the bracket 12, a first rotating shaft 14 rotatably mounted on one end of the first motor 13, a grinding wheel 15 fixedly mounted on one end of the first rotating shaft 14, a hinge 21 fixedly mounted on the top of the first frame 11, and a second frame 22 fixedly mounted on the outer surface of the hinge 21. Both sides of the second frame 22 are provided with an air inlet 23. The third frame 31 is slidably installed inside the first frame 11. An air intake 32 is provided at one end of the third frame 31. A first screen 33 is fixedly installed on the inner wall of the third frame 31. A second screen 34 is fixedly installed at the bottom of the first screen 33. A fourth frame 41 is fixedly installed at the rear end of the first frame 11. Three support rods 42 are fixedly installed on the inner wall of the fourth frame 41. A second motor 43 is fixedly installed at one end of each support rod 42. A second shaft 44 is rotatably installed at one end of each second motor 43. A fan blade 45 is fixedly installed at one end of the second shaft 44.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the working process of this convenient waste recycling grinder is as follows:
[0029] First, the user places the furniture to be sanded inside the first frame 11. Then, the user flips the top cover 2 to place the second frame 22 on top of the first frame 11. Next, the user starts the first motor 13, which drives the first rotating shaft 14 to rotate, which in turn drives the sanding wheel 15. The user then inserts their hand through the operating port 17 into the first frame 11 and sands the furniture using the sanding wheel 15. During the sanding process, the user activates three second motors 43. 43 will drive the corresponding second rotating shaft 44 and fan blade 45 to rotate, thereby forming an airflow that sucks the metal dust and wood chips generated during the furniture polishing process into the collection tank 3. Then, the first screen 33, the second screen 34, and the third screen 35 will filter the sucked-in air, and the metal dust or wood chips in the air will be filtered step by step. Afterwards, the user only needs to collect the metal dust or wood chips collected in the collection tank 3 for unified recycling and reuse to prevent the chips or metal dust generated during the polishing process from scratching the outer surface of the furniture.
