Description

Technical Field

[0001] This invention relates to the field of acrylic sheet production technology, and more particularly to a flame polisher for acrylic sheets. Background Technology

[0002] Acrylic, also known as specially treated plexiglass, is a next-generation product of plexiglass. It boasts numerous advantages, including excellent weather resistance and acid / alkali resistance, long lifespan, good light transmittance, superior insulation, and high plasticity. Through various processing techniques, acrylic sheets can be crafted into products with unique decorative effects. Therefore, based on its advantages, acrylic sheets have been widely used in various fields. However, acrylic sheets are highly sensitive to high temperatures; they deform above 85°C.

[0003] Based on the material characteristics of acrylic sheets, flame polishing is particularly suitable for the rapid and transparent polishing of irregular edges and corners such as rough sides, concave surfaces, inner holes, and curved edges of acrylic advertising crystal letters or craft carving products. It solves the problems that conventional grinding and polishing cannot achieve, and is environmentally friendly and economical.

[0004] Currently, flame polishing of acrylic sheets is usually done manually. Operators hold a spray gun to flame polish the edges and corners of the acrylic sheets placed on the workbench. Because the acrylic sheets need to be continuously moved or rotated, scratches are easily left on the surface, and the risk of manually holding a spray gun is relatively high. Summary of the Invention

[0005] To overcome the drawbacks of manually polishing the edges and corners of acrylic sheets by moving or rotating the sheets, which easily causes scratches and reduces the quality of the acrylic sheets, this invention provides a flame polisher for acrylic sheets that safely places the sheets and automatically rotates them.

[0006] A flame polisher for acrylic sheets includes a worktable, a slide rail, an oil tank, a winding wheel, and a flame nozzle. The slide rail is located on the rear side of the worktable, the oil tank is fixed to the rear side of the worktable by bolts, the flame nozzle is limited and slidably within the slide rail, the winding wheel is located on the side of the oil tank, and the connecting pipe between the oil tank and the flame nozzle is wound around the winding wheel. The device also includes a moving mechanism and a rotating mechanism.

[0007] Preferably, the moving mechanism includes a base plate, a placement plate, suction cups, and a pull rod. The base plate is slidably connected to the end face of the worktable, the placement plate is rotatably connected to the upper part of the base plate, suction cups are evenly distributed on the placement plate, and the pull rod is fixed to the front side of the base plate.

[0008] Preferably, the rotating mechanism includes a ratchet, a first fixed block, a wedge-shaped lever, a first return spring, a second fixed block, a ratchet rack, and a second return spring. The ratchet is fixed to the center of the bottom of the placement plate, the first fixed block is fixed to the eccentric position of the base plate, the wedge-shaped lever is slidably connected to the first fixed block and the first return spring is connected between the two, and the wedge-shaped lever can limit the rotation direction of the ratchet. The second fixed block is fixed to the left side of the front end of the worktable, the ratchet rack is slidably connected to the second fixed block and the second return spring is connected between the two, and the ratchet and the ratchet rack can contact each other.

[0009] Preferably, the device also includes a clamping mechanism, which includes a clamping bracket, a turntable, a connecting rod, a clamping plate, and a limiting rod. The clamping bracket is fixed to the rear side of the worktable, the turntable is rotatably connected to the middle of the clamping bracket, the limiting rod is square and slides on the clamping bracket, the lower part of the limiting rod is fixed to the clamping plate, the connecting rod is symmetrically arranged in the center and one end is hinged to the eccentric part of the turntable, and the other end is hinged to the limiting rod.

[0010] Preferably, the device also includes a limiting component, which includes a limiting block and a locking rod. The limiting block is symmetrically fixed to the left and right sides of the worktable, and the locking rod slides on the pull rod to limit the movement. The locking rod can engage with the limiting block.

[0011] Preferably, the device also includes a slanted rod and a wedge block. The slanted rod is symmetrically fixed to the front side of the base plate, and the wedge block is symmetrically fixed to the front end of the clamping plate. The slanted rod and the wedge block can make frictional contact.

[0012] Preferably, a reciprocating mechanism is also included, which includes a motor bracket, a servo motor, and a double connecting rod. The motor bracket is fixed to the right side of the rear end of the worktable, the servo motor is fixed to the motor bracket by bolts, and the output shaft of the servo motor is keyed to the double connecting rod. The other end of the double connecting rod is hinged to the flame nozzle.

[0013] The beneficial effects of this invention are:

[0014] 1. Equipped with a moving mechanism and a rotating mechanism, the acrylic sheet can be placed on the placement plate and fixed by suction cups. The flame nozzle slides along the slide rail to polish the sides of the acrylic sheet. By pulling the base plate forward, the ratchet and ratchet rack interact with each other, causing the placement plate to rotate regularly in one direction. This allows the sides of the acrylic sheet to be polished one by one without the need for manual handling or rotation, thus improving the quality of the acrylic sheet and increasing work efficiency.

[0015] 2. Equipped with a diagonal bar, wedge block, and clamping mechanism, the clamping plate automatically slides in opposite directions when the base plate is moved to the rear of the worktable to clamp and fix the acrylic plate, thus improving the automation level of the device.

[0016] 3. A limit component is provided. When the pull rod pushes the base plate to the rear of the worktable, the locking rod can engage with the limit block to limit and fix the base plate, thereby improving its stability. Attached Figure Description

Detailed Implementation

[0027] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0028] Example 1

[0029] A flame polisher for acrylic sheets, such as Figure 1 and Figure 2 As shown, the device includes a worktable 1, a slide rail 101, an oil tank 2, a winding wheel 201, and a flame nozzle 202. The slide rail 101 is provided on the rear side of the worktable 1. The oil tank 2 is fixed to the rear side of the worktable 1 by bolts. The flame nozzle 202 is limited and slids within the slide rail 101. The winding wheel 201 is provided on the side of the oil tank 2. The connecting pipe between the oil tank 2 and the flame nozzle 202 is wound around the winding wheel 201. An acrylic sheet is placed on the worktable 1 and the flame nozzle 202 polishes its side. The device also includes a moving mechanism 3 and a rotating mechanism 4.

[0030] like Figure 1 and Figure 3 As shown, the moving mechanism 3 includes a base plate 301, a placement plate 302, suction cups 303, and a pull rod 304. The base plate 301 is slidably connected to the end face of the worktable 1, and the placement plate 302 is rotatably connected to the upper part of the base plate 301. Suction cups 303 are evenly arranged on the placement plate 302, and the pull rod 304 is fixed to the front side of the base plate 301. When the acrylic sheet is placed on the placement plate 302, the suction cups 303 can fix the acrylic sheet. By rotating the placement plate 302, the flame nozzle 202 flame polishes the acrylic sheet edge by edge.

[0031] like Figure 1 , Figure 4 and Figure 5As shown, the rotating mechanism 4 includes a ratchet 401, a first fixed block 402, a wedge-shaped lever 403, a first return spring 404, a second fixed block 405, a ratchet rack 406, and a second return spring 407. The ratchet 401 is fixed to the center of the bottom of the placement plate 302. The first fixed block 402 is fixed to the eccentric position of the base plate 301. The wedge-shaped lever 403 is slidably connected within the first fixed block 402, and the first return spring 404 is connected between the two. The wedge-shaped lever 403 can limit the rotation direction of the ratchet 401. The second fixed block 405 is fixed to the left side of the front end of the worktable 1. The ratchet rack 406 is slidably connected within the second fixed block 405, and the second return spring 407 is connected between the two. 1. The ratchet 406 can contact the flame nozzle 202. After the flame nozzle 202 finishes polishing the side of the acrylic plate, the base plate 301 is pulled forward by the pull rod 304. The ratchet 401 will contact the ratchet 406 and be pushed to rotate. The wedge-shaped lever 403 can limit the rotation direction of the ratchet 401. The length of the ratchet 406 is 1 / 4 of the circumference of the ratchet 401. Therefore, it can drive the placement plate 302 to rotate at a right angle when pulled once. Then the base plate 301 is pushed back to reset. At this time, the acrylic plate on the placement plate 302 will face the flame nozzle 202 with the unpolished side, and then be polished by the flame nozzle 202. This cycle is repeated. The side of the acrylic plate can be accurately polished without manual control of the rotation angle.

[0032] Example 2

[0033] Based on Example 1, such as Figure 1 and Figure 6 As shown, it also includes a clamping mechanism 5, which includes a clamping bracket 501, a turntable 502, a connecting rod 503, a clamping plate 504, and a limiting rod 505. The clamping bracket 501 is fixed to the rear side of the worktable 1. The turntable 502 is rotatably connected to the middle of the clamping bracket 501. The limiting rod 505 is square and slides on the clamping bracket 501. The clamping plate 504 is fixed to the lower part of the limiting rod 505. The connecting rod 503 is symmetrically arranged in the center and one end is hinged to the eccentric part of the turntable 502, and the other end is hinged to the limiting rod 505. The clamping plate 504 is used to clamp and fix the acrylic plate located above the placement plate 302. By rotating the turntable 502, the connecting rod 503 can be driven, and the connecting rod 503 will drive the clamping plate 504 to slide in opposite or opposite directions, thereby realizing the clamping and release of the acrylic plate and improving the stability of the polishing process.

[0034] like Figure 1 and Figure 7As shown, it also includes a limiting component 6, which includes a limiting block 601 and a locking rod 602. The limiting block 601 is symmetrically fixed to the left and right sides of the worktable 1, and the locking rod 602 is limited and slidably mounted on the pull rod 304. The locking rod 602 can be engaged with the limiting block 601. When the base plate 301 is pushed to the rear of the worktable 1 by the pull rod 304, the locking rod 602 can be engaged with the limiting block 601, thereby limiting and fixing the base plate 301 and improving its stability. When it is necessary to unlock, the locking rod 602 can be slid upward while pulling the pull rod 304, and the locking rod 602 will disengage from the limiting block 601, so that the pull rod 304 can be pulled smoothly.

[0035] like Figure 1 and Figure 8 As shown, it also includes a slanted rod 701 and a wedge block 702. The slanted rod 701 is symmetrically fixed to the front side of the base plate 301, and the wedge block 702 is symmetrically fixed to the front end of the clamping plate 504. The slanted rod 701 and the wedge block 702 can make frictional contact. After the base plate 301 is pulled forward to rotate the acrylic plate, the base plate 301 is pushed backward to reset. The slanted rod 701 can contact and push the wedge block 702 to slide in opposite directions, thereby pushing the clamping plate 504 to slide in opposite directions. The effect achieved is that when the base plate 301 is moved to the rear side of the worktable 1, the clamping plate 504 automatically slides in opposite directions to clamp and fix the acrylic plate.

[0036] like Figure 1 and Figure 9 As shown, it also includes a reciprocating mechanism 8, which includes a motor bracket 801, a servo motor 802, and a double connecting rod 803. The motor bracket 801 is fixed to the right side of the rear end of the worktable 1. The servo motor 802 is fixed to the motor bracket 801 by bolts. The output shaft of the servo motor 802 is keyed to the double connecting rod 803. The other end of the double connecting rod 803 is hinged to the flame nozzle 202. After the servo motor 802 is turned on, the servo motor 802 can drive the double connecting rod 803 to rotate. The double connecting rod 803 will pull the flame nozzle 202 to slide back and forth on the slide rail 101, thereby realizing automated polishing.
