Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a device for removing burrs from a foamed polypropylene plate. Background Art

[0002] During the production of expanded polypropylene sheets, burrs often appear due to process limitations and the inherent properties of the material. These burrs not only affect the product's appearance but, in some applications requiring high precision, can also impair assembly and performance. Therefore, burr removal has become an essential step in the production of expanded polypropylene sheets.

[0003] At present, manual labor is mainly used to remove burrs. Because the foamed polypropylene board is light in texture, if it is not fixed during the deburring operation, it is easy to slide due to the touch of the tool or slight external force, thus affecting the deburring effect. The person needs to press the foam board with one hand to prevent it from sliding, and use the tool with the other hand to clean the burrs. Utility Model Content

[0006] The utility model provides a device for removing burrs of a foamed polypropylene board, comprising a workbench, a turntable, a pressing plate, a lifting mechanism, and a connecting frame. The turntable is fixed on the workbench and can rotate relative to the workbench. The connecting frame is vertically arranged on the workbench, the connecting frame is connected to the lifting mechanism, the lifting mechanism rotates in coordination with the pressing plate, the pressing plate is arranged above the turntable, and the lifting mechanism works to drive the pressing plate to move vertically toward or away from the turntable.

[0007] Preferably, an exhaust structure is further included, and the connecting frame is connected to the exhaust structure through a telescopic mechanism, and the telescopic mechanism is telescoped to drive the exhaust structure to move parallely in a direction away from or close to the turntable.

[0016] In order to make the technical purpose, technical solution and beneficial effects of the present invention clearer, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] The present invention provides a device for removing burrs from a foamed polypropylene board, as shown in the figure. The device comprises a workbench 1, a turntable 2, a pressing plate 3, a lifting mechanism 4, a connecting frame 5, and an exhaust structure. The workbench 1 is the basic support platform for the entire device. The turntable 2 is fixed to the workbench 1. The turntable is a conventional technology. The turntable 2 can rotate relative to the workbench 1 when in operation. The foamed polypropylene board is placed on the turntable 2. The turntable 2 works to facilitate workers to inspect the circumference of the board. The connecting frame 5 is configured as an inverted L-shaped structure. The connecting frame 5 is vertically arranged on the workbench 1. The connecting frame 5 is connected to the lifting mechanism 4. The lifting mechanism 4 rotates in coordination with the pressing plate 3. The pressing plate 3 is arranged above the turntable 2. The lifting mechanism 4 works to drive the pressing plate 3 to move vertically toward or away from the turntable 2. The pressing plate 3 can rotate relative to the lifting mechanism 4. A rubber pad is provided at the bottom of the pressing plate 3 to prevent damage to the board.

[0018] The device also includes an exhaust structure for exhausting smoke, comprising an exhaust hood 7 and an exhaust pipe connected to the exhaust hood 7. The exhaust hood 7 is connected to the connecting frame 5 via a telescopic mechanism. The telescopic mechanism is retractable to drive the exhaust hood 7 to move parallel to or away from the turntable 2. The design of the telescopic mechanism allows the exhaust hood 7 to move back and forth as needed, ensuring optimal dust collection and facilitating the cleaning of burrs on non-standard foamed polypropylene boards. The exhaust pipe is connected to an external exhaust device, which allows dust and other impurities generated during processing to be discharged from the work area, maintaining a clean environment. The telescopic mechanism includes at least two telescopic rods 6 spaced apart, one end of which is connected to the connecting frame 5 and the other end of which is connected to the exhaust hood 7.

[0019] Furthermore, the lifting mechanism 4 is configured as a cylinder, the cylinder body of which is fixed to the bottom of the "I"-shaped structure of the connecting frame 5 and is opposite to the turntable 2. The working end of the cylinder is connected to the middle part of the pressure plate 3 through a bearing for rotation. The rotation center line of the bearing is coaxial with the rotation center line of the turntable 2. When the cylinder is extended and retracted, it can drive the pressure plate 3 to move vertically so as to adjust the working height and apply pressure.

[0020] The method of using this device is as follows: place the foamed polypropylene board to be processed on the turntable 2, manually adjust the position of the foamed polypropylene board so that the board is in the optimal processing position, start the cylinder (lifting mechanism 4), and slowly lower the pressing plate 3 until the pressing plate 3 lightly presses on the board. The soft material (such as a rubber pad) at the bottom of the pressing plate 3 can prevent damage to the board. The exhaust hood 7 will adjust its position as the telescopic mechanism moves. Use tools (such as a cutting knife, a grinder, etc.) to remove burrs along the edge of the board. Start the turntable 2 to rotate it, and check the burrs on the other side surfaces.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate and not to limit the technical solutions of the present invention. Any equivalent replacement of the present invention and any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
