An adjustment mechanism is provided on the surface of the workbench, and a support plate is located above the workbench, connected to the adjustment mechanism. A column is fixedly connected to the top of the side of the workbench, and a grinding mechanism is fixedly connected to the top of the column. A mounting frame is provided on the surface of the grinding mechanism, and a dust collection hood is located at the end of the mounting frame. A negative pressure conduit is provided on the surface of the dust collection hood and connected to a negative pressure source.

[0003] While the aforementioned technology achieves a certain degree of burr removal on pallets, in actual use, it can only remove one edge at a time, requiring manual rotation of the pallet multiple times to ensure thorough removal of all four sides, resulting in low processing efficiency. Therefore, to address the inefficiency of this technology, we propose a burr removal device for molded pallets. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for polishing the rough edges of molded trays.

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

[0006] A device for sanding the rough edges of a molded tray includes a base. A rotating assembly provides a cooperating turntable in the middle of the base. The upper surface of the turntable has several placement areas, and each placement area has several limiting components. The bottom of the molded tray is placed in an adjacent limiting component. Two telescopic members are provided on one side of the upper end of the base. The output ends of the two telescopic members are respectively equipped with a longitudinal mounting frame and a transverse mounting frame. Both ends of the longitudinal mounting frame and the transverse mounting frame are equipped with sanding rollers. Each longitudinal mounting frame and the transverse mounting frame is equipped with a cooperating first motor corresponding to the sanding roller. The output end of the first motor is connected to the adjacent sanding roller through a transmission assembly.

[0007] Preferably, the rotating assembly includes a second motor and a reducer. The second motor is located in the middle of the ground inside the base, and the two ends of the reducer are respectively connected to the output end of the second motor and the turntable.

[0008] Preferably, the lower surface of the turntable is provided with a slide rail, and the base is provided with a corresponding guide seat for the slide rail.

[0009] Preferably, the limiting component includes a threaded hole, a screw, and a socket, with a plurality of sockets installed in the placement area via the screw and the threaded hole.

[0010] Preferably, the transmission assembly includes a transmission belt and pulleys, with the pulleys disposed at the ends of the grinding rollers, the output end of the first motor connected to the adjacent grinding rollers, and the adjacent pulleys connected to each other by the transmission belt.

[0011] Preferably, the base is provided with a protective cover, and a material inlet is provided on the side of the protective cover away from the telescopic member.

[0012] Preferably, the protective cover is a transparent cover, and a vacuum cleaner is connected to the rear side of the protective cover.

[0013] The present invention provides a device for sanding the rough edges of molded trays, which has the following advantages:

[0014] 1. In this utility model, through the cooperation of various components, the device achieves a certain degree of assembly line processing effect. Personnel only need to place the pallet to be processed on the turntable or remove the processed pallet from the turntable. The device automatically performs edge grinding and edge changing on the pallets, effectively improving the efficiency of edge grinding on molded pallets. Furthermore, since manual edge changing is unnecessary, it avoids errors in grinding position caused by inaccurate alignment during edge changing. Compared to traditional solutions, this approach not only improves processing efficiency but also enhances processing accuracy, thus facilitating the grinding of burrs on molded pallets.

[0015] 2. The second motor in this invention facilitates the rotation of the turntable, while the reducer amplifies the torque of the second motor, allowing it to rotate the turntable with less effort. The limiting component allows the operator to adjust the socket position according to the shape of the molded tray being processed, thus limiting the tray's movement during grinding and preventing it from affecting the grinding effect. The protective cover reduces noise during grinding and prevents dust from splashing directly into the environment, while the transparent cover allows for easy observation of the grinding process. Furthermore, the vacuum cleaner helps to absorb and clean the dust generated during grinding. Attached Figure Description

[0021] 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. Example

[0022] Reference Figure 1-4 A device for polishing the rough edges of a molded tray includes a base 1. A turntable 2 is provided in the middle of the base 1 via a rotating assembly. The upper surface of the turntable 2 is provided with several placement areas, and each placement area is provided with several limiting components. The bottom of the molded tray is placed in the adjacent limiting components. Two telescopic members 3 are provided on one side of the upper end of the base 1. The output ends of the two telescopic members 3 are respectively equipped with a longitudinal mounting frame 4 and a transverse mounting frame 5. Both ends of the longitudinal mounting frame 4 and the transverse mounting frame 5 are provided with polishing rollers 6. The polishing rollers 6 are existing technology and will not be described in detail in this solution. The longitudinal mounting frame 4 and the transverse mounting frame 5 are each provided with a first motor 7 corresponding to the polishing rollers 6. The output end of the first motor 7 is connected to the adjacent polishing rollers 6 through a transmission assembly. Example

[0023] Reference Figure 1-4 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0024] The rotating assembly includes a second motor 8 and a reducer 9. The second motor 8 is located in the center of the ground inside the base 1. The two ends of the reducer 9 are connected to the output end of the second motor 8 and the turntable 2, respectively. The second motor 8 facilitates the rotation of the turntable 2, while the reducer 9 amplifies the torque of the second motor 8, allowing the second motor 8 to rotate the turntable 2 with less effort. A slide rail 10 is provided on the lower surface of the turntable 2, and the base 1 has a corresponding guide seat for the slide rail 10. The slide rail 10 guides the turntable 2, thereby improving the stability of the turntable 2 during rotation. The limiting component includes threaded holes, screws 11, and sockets 12. Several sockets 12 are installed in the placement area through screws 11 and threaded holes. The setting of the limiting component allows the personnel to adjust the position of the sockets 12 according to the shape of the molded tray being processed during actual use. When the position of the sockets 12 is changed, the longitudinal mounting bracket 4 and the transverse mounting bracket 5 need to be modified accordingly to ensure that the grinding roller 6 can always contact and grind each side of the tray. This facilitates the sockets 12 to limit the molded tray and prevent the tray from moving during grinding and affecting the grinding effect.

[0025] The transmission assembly includes a transmission belt 13 and pulleys 14. The pulleys 14 are located at the ends of the grinding rollers 6. The output end of the first motor 7 is connected to the adjacent grinding rollers 6. The adjacent pulleys 14 are connected to each other through the transmission belt 13. The transmission assembly facilitates the driving of each grinding roller 6. The base 1 is provided with a protective cover 15. The side of the protective cover 15 away from the telescopic member 3 is provided with a material inlet. The protective cover 15 reduces the noise generated during grinding to a certain extent and prevents the grinding material from splashing directly into the outside and causing garbage. The protective cover 15 is a transparent cover. A vacuum cleaner 16 is connected to the rear of the protective cover 15. The transparent protective cover 15 also allows personnel to observe the grinding of the tray at any time. The vacuum cleaner 16 facilitates the absorption and cleaning of dust generated during grinding.

[0026] Operating principle and advantages: In the process of using this utility model, since the turntable 2 is provided with several placement areas, the personnel can first place the tray to be sanded in one of the placement areas. Then, by rotating the turntable 2 clockwise or counterclockwise, the tray is moved to one of the mounting frames. At this time, the telescopic component 3 can drive the mounting frame to move downward until the sanding roller 6 installed on the mounting frame contacts two sides of the tray. Thus, driven by the first motor 7, the sanding roller 6 is driven to rotate through the transmission component, thereby achieving the sanding of the two sides of the tray. After the two sides are sanded, the telescopic component 3 drives the mounting frame to return to its original position. Then, driven by the turntable 2, the tray is moved to the next mounting frame, so that the remaining two sides of the tray are sanded by the next mounting frame and the sanding roller 6 installed on the next mounting frame.

[0027] Furthermore, through the cooperation of the aforementioned components, this device achieves a certain degree of assembly line processing effect during use. Personnel only need to place the pallet to be processed on turntable 2 or remove the processed pallet from turntable 2. The device automatically performs edge grinding and edge changing on the pallets, effectively improving the efficiency of edge grinding on molded pallets. Since manual edge changing is unnecessary, it avoids errors in grinding position caused by inaccurate alignment during edge changing. Therefore, compared to traditional solutions, this approach not only improves processing efficiency but also processing accuracy, thus benefiting the use of molded pallet edge grinding.

[0028] It should be further explained that the second motor 8 facilitates the rotation of the turntable 2, while the reducer 9 amplifies the torque of the second motor 8, allowing it to rotate the turntable 2 with less effort. The slide rail 10 guides the turntable 2, improving its stability during rotation. The limiting component allows operators to adjust the position of the socket 12 according to the shape of the molded tray being processed. When the position of the socket 12 is changed, adjustments need to be made to the longitudinal mounting bracket 4 and the transverse mounting bracket 4. The frame 5 is modified accordingly to ensure that the grinding roller 6 can always contact and grind all sides of the tray. This allows the socket 12 to limit the molded tray, preventing the tray from moving during grinding and affecting the grinding effect. The protective cover 15 reduces the noise generated during grinding to a certain extent and prevents the grinding material from splashing directly into the outside and causing garbage. At the same time, the transparent protective cover 15 allows personnel to observe the grinding of the tray at any time, and the dust generated during grinding can be absorbed and cleaned to a certain extent by the vacuum cleaner 16.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
