Description

Technical Field

[0001] This invention relates to the field of acrylic sheet processing, and more particularly to an auxiliary marking machine for acrylic sheets. Background Technology

[0002] Acrylic, also known as PMMA or polymethyl methacrylate, is an important early-developed ductile material with good transparency, chemical stability, and weather resistance. It is easy to dye, easy to process, and has a beautiful appearance. It can be produced by casting, injection molding, extrusion, thermoforming, and other processes. Cast acrylic is mainly used for engraving.

[0003] Laser marking involves using a laser to engrave the desired pattern or logo onto an acrylic sheet. However, current laser marking machines can only engrave on one side. When engraving the back, it is necessary to release the acrylic sheet, flip it over, re-fix it, and then engrave it again, which is very inconvenient. Summary of the Invention

The second fixed rod is welded to the middle of the first fixed plate. The gear is rotatably connected to the second fixed rod. The second torsional elastic element is sleeved on the second fixed rod, with one end welded to the gear and the other end welded to the second fixed rod. The clamping plate is slidably connected to the first fixed plate. One end of the first rack is welded to the front end of the clamping plate, and the other end meshes with the gear.

[0008] Preferably, a flipping mechanism is also included, comprising a ratchet, a first fixed block, a second limiting block, a first elastic element, a second rack, a second guide rod, a second elastic element, and a second fixed plate. The ratchet is fixed to the slide rod, the first fixed block is welded to the moving block, the second limiting block is rotatably connected to the moving block, the first elastic element is sleeved on the second limiting block, one end of the first elastic element is welded to the second limiting block, and the other end is welded to the moving block, the second fixed plate is welded to the bottom of the frame, the second guide rod is slidably connected to the second fixed plate, the second rack is welded to the top of the second guide rod, and the second elastic element is sleeved on the second guide rod, one end of the second elastic element is welded to the second fixed plate, and the other end is welded to the second rack.

[0009] Preferably, the device also includes a lifting mechanism, which comprises a second fixed block, a second rotating rod, a striking plate, a top plate, and a third torsional elastic element. The second fixed block is welded to the bottom front end of the frame, the second rotating rod is rotatably connected to the second fixed block, the third torsional elastic element is sleeved on both ends of the second rotating rod, one end is welded to the second fixed block, and the other end is welded to the second rotating rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The acrylic sheet is fixed to the worktable by the first fixing plate and the clamping plate. Then, the acrylic sheet is moved by the moving block, detached from the worktable, flipped, and then pushed back into the worktable to achieve double-sided engraving.

[0015] 2. The ratchet and the second rack rotate automatically during movement, eliminating the need for workers to flip the acrylic sheet, thus optimizing the workflow and improving work efficiency. The impact plate drives the top plate, thereby releasing the first fixing plate from the acrylic sheet and pushing the acrylic sheet out, which optimizes the steps for workers to pick up the acrylic sheet.

[0016] 3. By limiting the ratchet to prevent rotation through the limit bar, the clamping mechanism is prevented from rotating, thus optimizing the fixing effect on the acrylic sheet and ensuring the stability of the spraying process. This achieves the goal of optimizing the spraying effect. When rotation is required, the restriction is released through the slide rail, eliminating the step of manually pulling the limit bar, optimizing the workflow and improving work efficiency.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] An auxiliary marking machine for acrylic sheets, such as Figure 1 and Figure 2 As shown, the device includes a cabinet 1, a cabinet door 2, a handle 21, a workbench 3, and a marking instrument 4. The cabinet door 2 is rotatably connected to the front of the cabinet 1, the handle 21 is welded to the cabinet door 2, the workbench 3 is welded to the upper end of the cabinet 1, and the marking instrument 4 is fixed to the upper rear part of the cabinet 1. It also includes a moving mechanism 5 and a clamping mechanism 6. The moving mechanism 5 is provided on the workbench 3, which can move the acrylic sheet. The clamping mechanism 6 is provided on the moving mechanism 5, which can fix the acrylic sheet. The marking instrument 4 includes a laser emitter and a computer, which can set the engraved pattern.

[0032] like Figure 3 and Figure 4As shown, the moving mechanism 5 includes a frame 51, a slide rod 53, a first limiting block 54, a moving block 55, and a first guide rod 56. The frame 51 is welded to the cabinet 1. The slide groove 52 is a groove on the side of the frame 51. The slide rod 53 is slidably connected in the slide groove 52. The first limiting block 54 is slidably connected in the frame 51. The slide rod 53 is rotatably connected to the inner end of the first limiting block 54. The moving block 55 is welded to the inner end of the slide rod 53. The first guide rod 56 is welded inside the moving block 55.

[0033] like Figure 5 and Figure 6 As shown, the clamping mechanism 6 includes a first fixed plate 61, a first rotating rod 62, a turntable 63, a first torsional elastic element 64, a first fixed rod 65, a clamping plate 66, a first rack 67, a gear 68, a second torsional elastic element 69, and a second fixed rod 610. The left end of the first fixed plate 61 is slidably connected to the first guide rod 56. One end of the first rotating rod 62 is rotatably connected to the right end of the first fixed plate 61, and the other end is rotatably connected to the turntable 63. The first fixed rod 65 is welded to the moving block 55. The turntable 63 is rotatably connected to the fixed rod. The rotating rod and the turntable 63 are clamped by the gap of the moving block 55. The first torsional elastic element 64 is sleeved on the first fixed rod 65, and one end is welded to the first fixed rod 610. On the turntable 63, the first fixing rod 65 is welded to the other end, and the second fixing rod 610 is welded to the middle of the first fixing plate 61. The gear 68 is rotatably connected to the second fixing rod 610. The second torsional elastic element 69 is sleeved on the second fixing rod 610, with one end welded to the gear 68 and the other end welded to the second fixing rod 610. The clamping plate 66 is slidably connected to the first fixing plate 61. One end of the first rack 67 is welded to the front end of the clamping plate 66, and the other end meshes with the gear 68. The inner sides of the first fixing plate 61 and the clamping plate 66 are provided with rubber stripes, which can better fix the acrylic plate and also prevent the inner sides of the first fixing plate 61 and the clamping plate 66 from leaving scratches on the side of the acrylic plate.

[0034] The operator pulls the first fixed plate 61 forward and backward, causing the first rotating rod 62 and turntable 63 to rotate. Simultaneously, the first torque elastic element 64 is twisted, pulling the clamping plate 66 to the left and right, causing the first rack 67 to move to both sides. This causes the gear 68 to rotate counterclockwise, twisting the second torque elastic element 69. The acrylic sheet to be marked is placed on the worktable 3. Under the return torque of the first and second torque elastic elements 64 and 69, the first fixed plate 61 and clamping plate 66 move towards the center, clamping the acrylic sheet and fixing it above the worktable 3. Then, the marking instrument 4 is turned on, the pattern is set, and after one side is finished, the marking instrument 4 is turned off, causing the clamping mechanism 6 to move forward. The slide bar 53 slides within the slide groove 52. When the clamping mechanism 6 is completely removed from the worktable 3, the clamping mechanism 6 is flipped. At this time, the slide bar 53 and the moving block 55 are also flipped. The clamping mechanism 6 is then pushed back onto the worktable 3. The marking instrument 4 is turned on to mark the other side of the acrylic sheet. After both sides are completed, the marking instrument 4 is turned off. The first fixing plate 61 is pulled forward and backward, and the clamping plate 66 is pulled to the left and right to remove the acrylic sheet. The acrylic sheet is fixed on the worktable 3 by the first fixing plate 61 and the clamping plate 66. The acrylic sheet is then moved by the moving block 55, removed from the worktable 3, flipped, and then pushed back into the worktable 3 to achieve double-sided engraving.

[0035] Example 2

[0036] Based on Example 1, such as Figure 7 and Figure 8 As shown, it also includes a flipping mechanism 7, which includes a ratchet 71, a first fixed block 72, a second limiting block 73, a first elastic element 74, a second rack 75, a second guide rod 76, a second elastic element 77, and a second fixed plate 78. The ratchet 71 is fixed to the slide rod 53. The first fixed block 72 is welded to the moving block 55. The second limiting block 73 is rotatably connected to the moving block 55. The first elastic element 74 is sleeved on the second limiting block 73. One end of the first elastic element 74 is welded to the second limiting block 73, and the other end is welded to the moving block 55. The second fixed plate 78 is welded to the bottom of the frame 51. The second guide rod 76 is slidably connected to the second fixed plate 78. The second rack 75 is welded to the top of the second guide rod 76. The second elastic element 77 is sleeved on the second guide rod 76. One end of the second elastic element 77 is welded to the second fixed plate 78, and the other end is welded to the second rack 75.

[0037] The clamping mechanism 6 moves forward, and the ratchet 71 also moves forward. When it passes the second rack 75, the ratchet 71 drives the clamping mechanism 6 to rotate. The number of teeth of the ratchet 71 is twice that of the second rack 75, so the ratchet 71 rotates 180 degrees after passing the second rack 75, pushing the clamping mechanism 6 back onto the worktable 3. Since the second limit block 73 restricts the ratchet 71 from rotating clockwise, the ratchet 71 presses the second rack 75 down, thereby compressing the second elastic element 77. When the ratchet 71 leaves the second rack 75, the second elastic element 77 rebounds, causing the second rack 75 to reset. Through the ratchet 71 and the second rack 75, they rotate automatically during the movement, eliminating the step of the worker flipping the rack, thereby optimizing the workflow and improving work efficiency.

[0038] like Figure 9 As shown, it also includes a lifting mechanism 8, which includes a second fixing block 81, a second rotating rod 82, a striking plate 83, a top plate 84, and a third torsional elastic element 85. The second fixing block 81 is welded to the bottom front end of the frame 51. The second rotating rod 82 is rotatably connected to the second fixing block 81. The third torsional elastic element 85 is sleeved on both ends of the second rotating rod 82, with one end welded to the second fixing block 81 and the other end welded to the second rotating rod 82. The striking plate 83 is welded to the second rotating rod 82 and is perpendicular to the frame 51. The top plate 84 is welded to the second rotating rod 82 and is parallel to the frame 51. The rear end of the top plate 84 is covered with rubber so that no scratches are left on the acrylic sheet when lifting it.

[0039] After both sides are marked, the clamping mechanism 6 is pulled forward. After the second rack 75 flips, it contacts the impact plate 83 and continues to move forward, pressing against the impact plate 83. The impact plate 83 then rotates counterclockwise around the second rotating rod 82, and the top plate 84 also rotates counterclockwise. At the same time, the third torque elastic element 85 is twisted. The top of the top plate 84 presses against the protrusion in the middle of the first fixed plate 61, causing the first fixed plate 61 to stop moving. This causes the turntable 63 to rotate, and the two first fixed plates 61 are released. In addition to fixing the acrylic sheet, after the top plate 84 continues to rotate, it pushes the acrylic sheet out of the clamping mechanism 6 from the rear end, making it easier for the staff to pick it up. After the acrylic sheet is taken out, the clamping mechanism 6 is pushed backward, and the top plate 84 and the impact plate 83 are reset under the return torque of the third torsional elastic element 85. The impact plate 83 drives the top plate 84, thereby releasing the first fixing plate 61 from fixing the acrylic sheet, and then pushing the acrylic sheet out, thus optimizing the steps for the staff to pick up the acrylic sheet.

[0040] like Figure 10As shown, it also includes a locking mechanism 9, which includes a limit rod 91, a third elastic element 92, and a third fixing plate 93. The third fixing plate 93 is welded to the first limit block 54, and the limit rod 91 is slidably connected to the third fixing plate 93. The bottom end of the limit rod 91 extends into the ratchet 71, and the third elastic element 92 is sleeved on the limit rod 91. One end of the third elastic element 92 is welded to the third fixing plate 93, and the other end is welded to the limit rod 91.

[0041] When spraying acrylic sheets, the limiting rod 91 restricts the ratchet 71 from rotating, thereby ensuring that the clamping mechanism 6 cannot rotate, optimizing the fixing effect of the clamping mechanism 6 on the acrylic sheet, and thus ensuring the stability of the spraying process and achieving the purpose of optimizing the spraying effect. When the clamping mechanism 6 needs to be flipped, the operator pulls up the limiting rod 91 and compresses the third elastic element 92 at the same time. After flipping, under the action of the rebound force of the third elastic element 92, the limiting rod 91 restricts the ratchet 71 from rotating again.

[0042] like Figure 11 As shown, it also includes an unlocking mechanism 10, which includes a slider 101 and a slide rail 102. The slider 101 is welded to the third fixed plate 93, and the slide rail 102 is welded to the top of the frame 51. Both ends of the slide rail 102 extend beyond the second rack 75. Before the ratchet 71 contacts the second rack 75, the limit rod 91 has already left the ratchet 71.

[0043] When the acrylic sheet needs to be flipped, the clamping mechanism 6 moves forward, and the slider 101 passes through the slide rail 102, causing the slider 101 to drive the limiting rod 91 to move upward. At the same time, the third elastic element 92 is compressed, and the limiting rod 91 leaves the ratchet 71, thereby releasing the restriction on the rotation of the ratchet 71. After flipping, the clamping mechanism 6 moves backward, and the slider 101 disengages from the slide rail 102. Under the action of the rebound force of the third elastic element 92, the limiting rod 91 restricts the ratchet 71 to rotate again, eliminating the step of manually pulling the limiting rod 91, optimizing the workflow, and achieving the goal of improving work efficiency.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
