Description

Technical Field

[0001] This utility model relates to the field of acrylic sheet production technology, specifically to a coating equipment for acrylic sheet production. Background Technology

[0002] Acrylic sheets, also known as specially treated plexiglass, are ordinary transparent acrylic sheets that are coated with an anti-reflective film to make them look more like glass. This achieves the function of preventing or eliminating glare and increasing the transmittance of the acrylic sheets. Currently, the coating process is performed on acrylic sheets using a vacuum coating machine.

[0003] When coating acrylic sheets using a vacuum coating machine, multiple aluminum strips need to be placed into crucibles beforehand. The aluminum strips are then heated and evaporated to coat the acrylic sheet. However, these multiple crucibles are fixed at different heights. For workers who are not very tall, the crucibles at higher positions are not easy to reach. They need to use tools such as stools to place the aluminum strips into the crucibles at higher positions. This process is too time-consuming and affects the efficiency of coating acrylic sheets. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a coating equipment for acrylic sheet production, which solves the problem that multiple crucibles are fixed at different heights, making it difficult for shorter workers to reach the crucibles at higher positions, requiring the use of stools or other tools.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating equipment for acrylic sheet production, comprising a vacuum coating machine and a sealing door rotatably connected to the front of the vacuum coating machine. The top and bottom of the inner cavity of the vacuum coating machine are fixedly connected to fixed plates. A support column is fixedly connected between two fixed plates. Several fixed sleeves are fixedly connected to the surface of the support column. Several fixed frames are fixedly connected to the surface of the fixed sleeves via connecting blocks. A resistance wire is fixedly connected to each fixed frame. Several mounting plates are fixedly connected to the opposite sides of the two fixed plates. A movable plate is fixedly connected between the upper and lower mounting plates. A sliding groove is formed on the side of the movable plate away from the support column. Several sliding blocks are slidably connected inside the sliding groove. A crucible adapted to the resistance wire is fixedly connected to the side of the sliding block away from the support column. A movable block is fixedly connected to the side of the sliding block near the support column. A first spring is fixedly connected between two adjacent movable blocks. A pull rod is fixedly connected to the uppermost movable block.

[0006] Preferably, a rectangular plate is fixedly connected to each of the two mounting plates on opposite sides. A sliding cylinder is fixedly connected to the side of the rectangular plate near the moving plate. A sliding rod is slidably connected inside the sliding cylinder. One end of the sliding rod is fixedly connected to the moving plate. A second spring is fixedly connected inside the sliding cylinder and between the rectangular plate and the sliding rod.

[0007] Preferably, two limiting plates are fixedly connected to the top of the mounting plate below, and the limiting plates are fixedly connected to the moving block at the bottom.

[0008] Preferably, a stop plate adapted to the pull rod is fixedly connected to the rectangular plate below.

[0009] Preferably, a rotating ring is rotatably connected to the surface of the fixed plate, and a support ring is fixedly connected to the surface of the rotating ring via a connecting plate.

[0010] Preferably, a plurality of support rods are fixedly connected between the opposite sides of the two support rings.

[0011] Beneficial effects

[0012] This invention provides a coating equipment for acrylic sheet production. Compared with existing technologies, it has the following advantages:

[0013] (1) This utility model moves by pushing the moving plate inward. The moving plate will drive multiple crucibles to move inward between the fixed frame and the resistance wire through multiple sliding blocks. Then, the pull rod is pulled down, and the pull rod will pull the uppermost moving block to move down. The uppermost moving block will press down on multiple moving blocks and the first spring, driving multiple moving blocks to move down. Multiple moving blocks will drive multiple crucibles to move down through sliding blocks, so that multiple crucibles can be moved down to a lower position easily. Multiple aluminum strips can be placed in multiple crucibles quickly, which can be adapted to workers of different heights and is more convenient to operate.

[0014] (2) This utility model can effectively limit the pull rod by pulling it down and then pushing it down to the bottom of the baffle plate. The pull rod will limit the multiple moving blocks after they move down, thereby temporarily fixing the multiple crucibles that have moved down, and freeing up your hands to add aluminum strips to the crucibles.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a coating equipment for acrylic sheet production, including a vacuum coating machine 1 and a sealing door 2 rotatably connected to the front of the vacuum coating machine 1. A vacuum pump is installed on the top of the vacuum coating machine 1, and a vent pipe is connected to the vacuum pump. One end of the vent pipe passes through the vacuum coating machine 1 and extends into the interior of the vacuum coating machine 1. Fixed plates 3 are fixedly connected to the top and bottom of the inner cavity of the vacuum coating machine 1. A support column 4 is fixedly connected between two fixed plates 3. Several fixed sleeves 5 are fixedly connected to the surface of the support column 4. Several fixed frames 6 are fixedly connected to the surface of the fixed sleeves 5 through connecting blocks. A resistance wire 7 is fixedly connected to the fixed frame 6. The resistance wire 7 is electrically connected to an external power source. The control switch controls the power on and off. Several mounting plates 8 are fixedly connected to the opposite side of the two fixed plates 3. A movable plate 9 is fixedly connected between the upper and lower mounting plates 8. A sliding groove 10 is opened on the side of the movable plate 9 away from the support column 4. Several sliding blocks 11 are slidably connected inside the sliding groove 10. A crucible 12 adapted to the resistance wire 7 is fixedly connected to the side of the sliding block 11 away from the support column 4. The crucible 12 is a graphite crucible. A movable block 13 is fixedly connected to the side of the sliding block 11 close to the support column 4. A first spring 14 is fixedly connected between two adjacent movable blocks 13. The first spring 14 is made of high temperature resistant alloy. A pull rod 15 is fixedly connected to the uppermost movable block 13.

[0023] Furthermore, to facilitate the outward movement and resetting of the movable plate 9, a rectangular plate 16 is fixedly connected to the opposite side of each of the two mounting plates 8. A sliding cylinder 17 is fixedly connected to the side of the rectangular plate 16 closest to the movable plate 9. A sliding rod 18 is slidably connected inside the sliding cylinder 17. One end of the sliding rod 18 is fixedly connected to the movable plate 9. A second spring 19 is fixedly connected inside the sliding cylinder 17 and between the rectangular plate 16 and the sliding rod 18. The elastic force of both the first spring 14 and the second spring 19 is within the range that can be pulled by human force.

[0024] Furthermore, in order to fix the bottommost movable block 13, two limiting plates 20 are fixedly connected to the top of the lower mounting plate 8, and the limiting plates 20 are fixedly connected to the bottommost movable block 13.

[0025] Furthermore, in order to facilitate hooking the pull rod 15 onto the blocking plate 21, a blocking plate 21 adapted to the pull rod 15 is fixedly connected to the lower rectangular plate 16.

[0026] Furthermore, in order to place the acrylic sheet, a rotating ring 22 is rotatably connected to the surface of the fixing plate 3, and a support ring 23 is fixedly connected to the surface of the rotating ring 22 through a connecting plate. Several support rods 24 are fixedly connected between the opposite sides of the two support rings 23.

[0027] In use, after coating multiple acrylic sheets inside the vacuum coating machine 1, the sealing door 2 is opened. The operator removes the acrylic sheets from the vacuum coating machine 1 and then pushes the moving plate 9 inward. The moving plate 9, through multiple sliding blocks 11, moves multiple crucibles 12 inward, causing them to move to the position between the fixed frame 6 and the resistance wire 7. Then, the pull rod 15 is pulled down, causing the uppermost moving block 13 to move downward. The moving block 13 presses down on the uppermost first spring 14, which in turn presses down on the multiple moving blocks 13 and the first spring 14, pulling the multiple moving blocks 13 down. Then, the pull rod 15 is pushed inward again, moving its rear end below the blocking plate 21 to hook and limit its movement. This limits the downward movement of multiple moving blocks 13. The downward movement of multiple moving blocks 13 will drive multiple crucibles 12 to move downward through sliding block 11, so that the crucibles 12 are moved to a height that can be reached. Multiple aluminum strips are placed into multiple crucibles 12 respectively. Then, the pull rod 15 is pulled outward to move out of the blocking plate 21. Through the force of multiple first springs 14, multiple moving blocks 13 are pushed upward to reset. Finally, the operator no longer applies the inward force to the pull rod 15. Through the force of the second spring 19, the sliding rod 18 is pushed outward. The two sliding rods 18 will push the moving plate 9 to move outward to reset. The moving plate 9 will drive multiple crucibles 12 to move below the resistance wire 7. The above operation is repeated to add aluminum strips to multiple crucibles 12.

[0028] Next, place the new acrylic sheet into the vacuum coating machine 1 and close the sealing door 2. Use the vacuum pump on the vacuum coating machine 1 to evacuate the vacuum coating machine 1 to a vacuum state. Then, energize and heat multiple resistance wires 7. The resistance wires 7 will heat the aluminum strip in the crucible 12. The aluminum strip is heated to the evaporation temperature through the resistance wires 7. After the aluminum strip evaporates, it forms a gas phase, which is then deposited on the surface of the cooled acrylic sheet to form a film.
