Description

Technical Field

[0001] This utility model relates to a polishing device for building wall signage, belonging to the technical field of polishing equipment for building wall signage. Background Technology

[0002] In locations such as hospitals, schools, and industrial parks, signs are typically installed to help people identify building numbers and floors. These signs are commonly made of acrylic sheets, which require polishing during production. For example, an acrylic sheet polishing device, as mentioned in authorization announcement number CN220029791U, includes a polishing table, a polishing device, and symmetrically arranged vacuum suction cups. The polishing table has a receiving groove for accommodating the vacuum suction cups, and a receiving component for storing the vacuum suction cups within the receiving groove. Support components are provided at both ends of the polishing table.

[0003] In this device, acrylic sheets adsorbed by vacuum suction cups can be supported and clamped to prevent them from falling off after the vacuum suction cups are retracted. However, in actual application, researchers found that during the polishing process of acrylic sheet signs, debris accumulates on the surface of the support frame to be supported, resulting in poor support effect for one side of the polished acrylic sheet sign. Furthermore, it is not convenient to flip the acrylic sheet sign over, which is not user-friendly. Utility Model Content

[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. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5 This utility model provides the following technical solution: a polishing device for building wall signs, including a polishing box 1, a left and right slide rail box 2 that is fixedly connected to the top surface of the polishing box 1, a front and rear slide rail box 3 that is slidably connected to the bottom surface of the left and right slide rail box 2, a reduction motor 4 that is fixedly connected to the front end of the front and rear slide rail box 3 and one end of the left and right slide rail box 2, threaded rods 5 that are provided in the inner cavity of the front and rear slide rail box 3 and the inner cavity of the left and right slide rail box 2, a downward electric push rod 6 that is slidably connected to the bottom surface of the left and right slide rail box 2, a protective cover 7 that is provided in the inner cavity of the polishing box 1, a shielding electric push rod 8 that is fixedly connected to the opposite side surface of the two protective covers 7, a shielding plate 9 that is fixedly connected to the telescopic end of the shielding electric push rod 8, a clamping electric push rod 10 that is movably connected to the opposite side surface of the two protective covers 7 through bearings, a servo motor 11 that is fixedly connected to the sleeve end of the two clamping electric push rods 10, and a support frame 12 that is fixedly connected to the telescopic end of the two clamping electric push rods 10.

[0024] In use, first place the acrylic label on the top surface of the vacuum suction cup 17. Activating the vacuum suction cup 17 will adsorb and limit the label. Then, extend the upper and lower electric push rods 16 to raise the label until its center point is level with the center point of the support frame 12. Next, extend the lower electric push rod 6 to drive the polishing motor 13 downwards. The polishing motor 13 then rotates the polishing plate to polish the label. Then, control the reduction motor 4 at the front end of the front and rear slide rail boxes 3 to rotate the threaded rod 5 inside the cavity. Since the sliding block 14 at the top of the lower electric push rod 6 is threadedly connected to the outer surface of the threaded rod 5, the lower electric push rod 6 assembly moves forward and backward as the threaded rod 5 rotates. Similarly, activating the reduction motor 4 at one end of the left and right slide rail boxes 2 will drive the lower electric push rod 6 assembly to move left and right, allowing for a more thorough polishing of the label surface.

[0025] As a preferred technical solution of the polishing device for building wall signs according to this utility model, a polishing motor 13 is fixedly connected to the telescopic end of the downward electric push rod 6, and a polishing plate is fixedly connected to the output end of the polishing motor 13; the polishing motor 13 drives the rotation of the polishing plate, which can perform polishing operation on the sign.

[0026] As a preferred technical solution of the polishing device for building wall signs of this utility model, the top surface of the downward electric push rod 6 and the top surface of the front and rear slide rail boxes 3 are both fixedly connected to sliding blocks 14. The two sliding blocks 14 are respectively threaded and connected to the outer surfaces of the two threaded rods 5. The bottom surfaces of the left and right slide rail boxes 2 and the bottom surfaces of the front and rear slide rail boxes 3 are all provided with grooves that match the structural dimensions of the sliding blocks 14. One end of the threaded rod 5 is fixedly connected to the output end of the reduction motor 4, and the end of the threaded rod 5 away from the reduction motor 4 is fixedly connected to a bearing body. The two threaded rods 5 are respectively connected to the left and right slide rail boxes 2 and the front and rear slide rail boxes 3 through the bearing bodies, ensuring that the two reduction motors 4 can drive the rotation of the two threaded rods 5, thereby causing the two sliding blocks 14 to move.

[0027] As a preferred technical solution of the polishing device for building wall signs of this utility model, the bottom surface of the inner cavity of the polishing box 1 is fixedly connected with an upper and lower electric push rod 16, and the telescopic end of the upper and lower electric push rod 16 is fixedly connected with a vacuum suction cup 17; wherein the vacuum suction cup 17 is a common device that can be used to absorb and limit flat plate-shaped objects, and is a known prior art, which will not be described in detail here.

[0028] Example 2

[0029] Please see Figure 1 and Figure 5 The difference between this embodiment and Embodiment 1 is that:

[0030] Connecting rods 15 are fixedly connected to both the top and bottom surfaces of the protective cover 7. The end of the connecting rod 15 away from the protective cover 7 is fixedly connected to the polishing box 1. An open slot is provided through the protective cover 7 near the baffle plate 9. The baffle plate 9 is slidably connected to the protective cover 7. The output ends of two servo motors 11 are fixedly connected to two clamping electric push rods 10 respectively. The ends of the two servo motors 11 away from the clamping electric push rods 10 are fixedly connected to the polishing box 1. The baffle plate 9 provides protection for the open slot. The servo motors 11 can drive the rotation of the clamping electric push rods 10.

[0031] It should be noted that, with the assistance of those skilled in the art, all electrical components in this case, including the geared motor 4, the downward electric push rod 6, the blocking electric push rod 8, the clamping electric push rod 10, the servo motor 11, the polishing motor 13, and the up and down electric push rods 16, should be connected to their compatible power supplies via wires. Furthermore, a suitable controller, such as a PLC controller or a microcontroller, should be selected based on the actual situation to meet the control requirements. The specific connections and control sequence should refer to the working principle described below, where the electrical connections are completed according to the sequential working order of each electrical component. The detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, without further explanation of the electrical control.

[0032] The working principle and usage process of this utility model are as follows: After polishing the top surface of the sign, the extension and retraction of the blocking electric push rod 8 and the extension of the clamping electric push rod 10 are controlled. The blocking electric push rod 8 drives the blocking plate 9 to rise, exposing the open slot on one side of the protective cover 7. The extension of the clamping electric push rod 10 drives the movement of the support frame 12 to support and clamp the sign. Further, the vacuum suction cup 17 is stopped, and the upper and lower electric push rods 16 are retracted. At this time, the vacuum suction cup 17 leaves the sign. Then, the servo motor 11 is started, which can drive the rotation of the combination of the clamping electric push rod 10 and the support frame 12, thereby flipping the sign.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
