[0002] With the booming development of the advertising industry, acrylic sheets have become the core material for billboard production due to their good light transmission, bright colors, and durability. In the acrylic sheet processing, the edge trimming process plays a key role in the appearance quality and installation compatibility of the billboard and is an important piece of equipment to ensure the quality of the billboard.

[0003] However, existing acrylic sheet trimming devices have certain shortcomings. Traditional devices usually require operators to hold and fix the acrylic sheet and trim it with grinding tools. This method is not only inefficient and labor-intensive, but also requires operators to frequently rotate or flip the sheet when dealing with different edges of the acrylic sheet. The operation is cumbersome and difficult to meet the needs of mass production.

[0004] Therefore, there is a need for an edge trimming device for acrylic sheet processing to solve the above-mentioned technical problems. Utility Model Content

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] like Figures 1-5 As shown, an edge-trimming device for acrylic sheet processing includes a worktable 1. A support frame 2 is fixedly connected to the upper surface of the worktable 1. The support frame 2 is firmly connected to the worktable 1 by welding, ensuring the stability of the overall structure. Its shape is a U-shaped frame structure. This structural design can provide a stable installation base for the positioning component 3, while not hindering the operation of the rotating component 4 inside the worktable 1. Under the premise of ensuring support strength, it saves materials to the maximum extent and reduces the overall weight of the device.

[0022] A positioning component 3 is provided on the inner side of the support frame 2. The positioning component 3 includes a motor 301 fixedly installed on the upper surface of the support frame 2, a threaded rod 302 cooperating with a threaded cylinder 303, and the outer surface of the threaded rod 302 rotatably connected to the inner wall of the support frame 2 through a bearing. The threaded cylinder 303 is threadedly connected to the outer surface of the threaded rod 302. A pressure plate 304 is fixedly connected to the end of the threaded cylinder 303 away from the motor 301. The outer surface of the pressure plate 304 is covered with a rubber pad. The side of the rubber pad that contacts the acrylic sheet is designed with anti-slip texture, which increases the friction between the rubber pad and the acrylic sheet, and can more firmly press the acrylic sheet, preventing the acrylic sheet from shifting during the trimming process.

[0023] The inner wall of the pressure plate 304 is slidably connected to two limiting posts 305. The limiting posts 305 are cylindrical with smooth surfaces. One end of the limiting post 305 is fixedly connected to the upper surface of the workbench 1 by welding, and the other end is fixedly connected to the inner wall of the support frame 2 by welding. This connection method ensures the stability of the limiting posts 305 and provides guidance for the up and down movement of the pressure plate 304, so that the pressure plate 304 can be pressed down smoothly in the vertical direction, avoiding tilting during movement, ensuring that the acrylic sheet is evenly stressed when fixed, and improving the stability of fixing the acrylic sheet.

[0024] The worktable 1 is equipped with a rotating assembly 4. The rotating assembly 4 includes a motor 401 fixedly installed at the bottom of the worktable 1. The output end of the motor 401 is fixedly connected to a rotating shaft 402. The outer surface of the rotating shaft 402 is rotatably connected to the inner wall of the worktable 1 through a bearing, which ensures the flexibility and stability of the rotation of the rotating shaft 402.

[0025] A drive gear 403 is fixedly connected to the end of shaft 402 furthest from motor 401. A driven gear 404 meshes with the outer surface of the drive gear 403, and the two cooperate to transmit power and adjust the rotational speed. A second shaft 405 is fixedly connected to the upper surface of the driven gear 404. The outer surface of the second shaft 405 is rotatably connected to the inner wall of the worktable 1 via a tapered roller bearing. This bearing can simultaneously withstand radial and axial forces, ensuring the stability of the second shaft 405 during rotation. A bearing plate 406, with a circular structure, is fixedly connected to the end of the second shaft 405 furthest from the driven gear 404.

[0026] The inner wall of the support plate 406 is rotatably connected with a ball bearing 407. The outer surface of the ball bearing 407 rolls in contact with the upper surface of the worktable 1. When the support plate 406 rotates, the ball bearing 407 rolls on the upper surface of the worktable 1, which reduces the friction when the support plate 406 rotates, making the support plate 406 drive the acrylic plate to rotate more smoothly and flexibly, and making it easier to adjust the acrylic plate to the appropriate trimming position.

[0027] A vertical plate 5 is fixedly connected to the outer surface of the workbench 1. The vertical plate 5 is bolted to the workbench 1, making installation and disassembly convenient. The vertical plate 5 is a rectangular plate structure. A motor 6 is fixedly mounted on the outer surface of the vertical plate 5. The speed of the motor 6 can be adjusted according to the actual needs of the trimming process to meet the requirements of different trimming processes. A reciprocating lead screw 7 is fixedly connected to the output end of the motor 6. The reciprocating lead screw 7 is threadedly connected to the limit frame 8. This connection method allows the reciprocating lead screw 7 to drive the limit frame 8 to perform reciprocating linear motion when the motor 6 rotates.

[0028] The outer surface of the reciprocating lead screw 7 is threadedly connected to the limit frame 8. The limit frame 8 is made of aluminum alloy, which is lightweight and has a certain strength. The outer surface of the limit frame 8 is slidably connected to the inner wall of the vertical plate 5 through a linear guide rail. The linear guide rail has the characteristics of high precision and low friction, which ensures the stability and accuracy of the limit frame 8 during the reciprocating motion.

[0029] An electric push rod 9 is fixedly installed on the inner wall of the limiting frame 8. The electric push rod 9 is a self-locking type, automatically locking after being adjusted to the appropriate position to prevent displacement due to external force. A sliding frame 10 is fixedly connected to the output end of the electric push rod 9. The sliding frame 10 is U-shaped, and its outer surface slides against the inner wall of the limiting frame 8, providing strong support for the motor 11 and the grinding wheel 12. The motor 11 is fixedly installed on the inner wall of the sliding frame 10, driving the grinding wheel 12 to rotate at high speed, achieving efficient edge trimming of the acrylic sheet. The grinding wheel 12 is fixedly connected to the output end of the motor 11. The grinding wheel 12 is made of diamond abrasive, featuring high hardness and good wear resistance, enabling fast and precise edge trimming of the acrylic sheet, ensuring both quality and efficiency.

[0030] Working principle: In use, first place the acrylic sheet to be trimmed on the support plate 406, start motor 301, the output end of motor 301 drives the threaded rod 302 to rotate, the threaded rod 302 is threadedly connected to the threaded cylinder 303, so that the threaded cylinder 303 drives the pressure plate 304 to move downward along the limit post 305, thereby pressing and fixing the acrylic sheet. Subsequently, if it is necessary to trim different edges of the acrylic sheet, start motor 401, the output end of motor 401 drives the rotating shaft 402 to rotate, the driving gear 403 on the rotating shaft 402 meshes with the driven gear 404, thereby driving the rotating shaft 405 and the support plate 406 to rotate. At this time, the support plate 406 drives the ball bearings 407. The acrylic sheet is rotated on the upper surface of the workbench 1 to facilitate adjustment to a suitable trimming position. At this time, motor 6 is started, which drives the reciprocating screw 7 to rotate, causing the limiting frame 8 to reciprocate along the reciprocating screw 7. At the same time, electric push rod 9 is started, which pushes the sliding frame 10 to move close to the acrylic sheet on the inner wall of the limiting frame 8. This will drive motor 11 and grinding wheel 12 to move closer to the acrylic sheet, thereby adjusting the distance between the grinding wheel 12 and the acrylic sheet. Finally, motor 11 is started, which drives the grinding wheel 12 to rotate at high speed to perform trimming operations on the acrylic sheet. Through the coordinated operation of the above components, efficient and convenient trimming operations on the acrylic sheet are achieved.
