Description

Technical Field

[0001] This utility model relates to the field of edge cutting device technology, and in particular to an edge cutting device for acrylic sheet production. Background Technology

[0002] Acrylic sheets are widely used in advertising, furniture decoration, and medical devices due to their excellent light transmittance, weather resistance, and processing performance. Cutting is a crucial step in the production of acrylic sheets, especially edge trimming, which directly affects the dimensional accuracy, edge smoothness, and adaptability for subsequent processing.

[0003] Traditional edge cutting devices often have fixed clamping structures that can only accommodate acrylic sheets of specific sizes. This is inconvenient when processing sheets of different widths and thicknesses. During the cutting process, existing devices often rely on manual pushing for feeding. Since acrylic sheets are brittle, uneven force during manual pushing can cause the sheet to wobble, resulting in problems such as skewed edges and chipped edges. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0021] To address the problems existing in the background art, this application proposes the following technical solution: a cutting device for acrylic sheet production, comprising a frame 1, a rotating rod 9 rotatably connected to the frame 1, a saw blade 10 fixedly connected to one end of the rotating rod 9, a drive assembly for driving the rotating rod 9 to rotate on the frame 1, a support plate 11 fixedly connected to the top of the frame 1, a lead screw 13 rotatably connected to the support plate 11, a second motor 12 fixedly connected to the outside of the support plate 11, the output end of the second motor 12 fixedly connected to the lead screw 13, a nut seat 15 threadedly connected to the outside of the lead screw 13, a first guide rod 14 fixedly connected to the support plate 11, the first guide rod 14 penetrating the nut seat 15, a size adjustment assembly provided on the top of the nut seat 15, and a clamping assembly provided in the size adjustment assembly.

[0022] The rotating rod 9 drives the saw blade 10 to rotate at high speed, directly completing the edge cutting operation of the acrylic sheet. The drive component provides continuous power to the saw blade 10, ensuring a smooth and efficient cutting process. In conjunction with the operating method, the second motor 12 drives the lead screw 13 to rotate, causing the nut seat 15 to move smoothly along the first guide rod 14, thereby feeding the acrylic sheet towards the saw blade 10. This achieves automated cutting, replacing manual pushing, reducing labor intensity, and ensuring a smooth cut through uniform feeding.

[0023] The drive assembly is a first motor 2 fixedly connected in the frame 1. A first rotating shaft 5 and a second rotating shaft 7 are rotatably connected in the frame 1. A first gear 6 is fixedly connected to the outside of the first rotating shaft 5, and a second gear 8 is fixedly connected to the outside of the second rotating shaft 7. The second rotating shaft 7 is coaxially fixedly connected to the rotating rod 9. A sprocket 3 is fixedly connected to the output end of the first motor 2 and one end of the first rotating shaft 5. A chain 4 is sleeved on the outside of the sprocket 3.

[0024] The drive assembly drives the first shaft 5 to rotate via the first motor 2, sprocket 3, and chain 4. Power is then transmitted to the second shaft 7 and rotating rod 9 through the meshing of the first gear 6 and second gear 8, ultimately driving the saw blade 10 to rotate. The transmission method using chain 4 and sprocket 3 offers high transmission efficiency and stability, ensuring continuous power transmission and maintaining a stable rotational speed for the saw blade 10. This solves the problem of speed fluctuations caused by slippage in traditional belt drives.

[0025] The size adjustment assembly includes a first clamping seat 16 and a second clamping seat 19. A slide plate 20 is fixedly connected to one end of the second clamping seat 19. A rectangular sliding hole is provided on the side wall of the first clamping seat 16, and the slide plate 20 is slidably connected in the rectangular sliding hole. A positioning bolt 21 is threadedly connected to the bottom of the first clamping seat 16, and one end of the positioning bolt 21 abuts against the slide plate 20. An electric push rod 17 is fixedly connected to the bottom of the nut seat 15, and the output end of the electric push rod 17 is fixedly connected to the first clamping seat 16. A second guide rod 18 is fixedly connected to the bottom of the first clamping seat 16, and the second guide rod 18 passes through the nut seat 15. The clamping assembly consists of clamping plates disposed in the first clamping seat 16 and the second clamping seat 19. A threaded rod 22 is rotatably connected to the top of the clamping plate, and the two threaded rods 22 are threadedly connected to the first clamping seat 16 and the second clamping seat 19 respectively. A third guide rod 23 is fixedly connected to the top of the clamping plate, and the third guide rod 23 passes through the corresponding first clamping seat 16 and the second clamping seat 19.

[0026] The size adjustment component slides through the rectangular sliding hole via the slide plate 20, allowing for flexible adjustment of the spacing between the first and second clamping seats 19. Combined with the usage method, it can quickly adapt to acrylic sheets of different widths. After adjustment, tightening the positioning bolt 21 fixes the spacing. The operation is simple and the fixation is secure, solving the problem of traditional devices requiring replacement of clamping components to adapt to different sized sheets. The electric push rod 17 can drive the first clamping seat 16 to rise and fall, adjusting the height distance between the acrylic sheet and the saw blade 10, ensuring the saw blade 10 accurately cuts the edge of the sheet and avoids problems such as excessive cutting or incomplete cutting due to improper height. The second guide rod 18 provides guidance for the lifting and lowering of the clamping seat, preventing it from shifting and ensuring height adjustment accuracy. In the clamping assembly, rotating the threaded rod 22 drives the clamping plate to move up and down, achieving clamping and fixing of the acrylic sheet. The third guide rod 23 ensures smooth movement of the clamping plate, preventing tilting. This clamping method can adapt to acrylic sheets of different thicknesses, and the large contact area between the clamping plate and the sheet ensures a secure clamping, preventing sheet displacement during cutting and avoiding damage to the sheet surface from excessive clamping. The overall structure balances the flexibility of size adjustment with the stability of clamping, greatly improving the device's adaptability to acrylic sheets of different specifications and the quality of edge cutting.

[0027] The usage method of this embodiment is as follows:

[0028] According to the width of the acrylic sheet to be cut, loosen the positioning bolt 21 at the bottom of the first clamping seat 16, push the second clamping seat 19 to make the slide plate 20 slide in the rectangular sliding hole, adjust the distance between the first clamping seat 16 and the second clamping seat 19 to match the width of the sheet; tighten the positioning bolt 21 so that one end of the bolt abuts against the slide plate 20 to fix the distance between the two clamping seats.

[0029] Place the acrylic sheet under the clamping plates of the first clamping seat 16 and the second clamping seat 19, and rotate the threaded rods 22 on the top of the two clamping seats respectively to drive the clamping plates to move downward along the third guide rod 23 until the clamping plates are in close contact with the surface of the acrylic sheet, firmly clamping the sheet and ensuring that the sheet will not shake during the cutting process.

[0030] Start the electric push rod 17 to lift the first clamping seat 16 and the fixed acrylic plate. Through the guiding action of the second guide rod 18, the height distance between the plate and the saw blade 10 is precisely adjusted so that the saw blade 10 is aligned with the edge of the plate to be cut. After adjustment, turn off the electric push rod 17.

[0031] Simultaneously, the first motor 2 and the second motor 12 are started. The first motor 2 drives the rotating rod 9 and the saw blade 10 to rotate at high speed through the sprocket 3, chain 4 and gear transmission. The second motor 12 drives the lead screw 13 to rotate, so that the nut seat 15 moves smoothly along the first guide rod 14, thereby driving the acrylic plate to feed towards the saw blade 10. When the plate passes the saw blade 10, the saw blade 10 cuts its edge until the cutting operation of the entire edge is completed.

[0032] After cutting is completed, turn off the first motor 2 and the second motor 12, the saw blade 10 stops rotating, and the nut seat 15 stops moving; rotate the threaded rod 22 in the opposite direction to raise the clamping plate, loosen the acrylic plate and remove it.
