Description

Technical Field

[0001] This utility model relates to the field of plastic sheet processing technology, specifically a large plastic sheet bending and shaping device. Background Technology

[0002] Plastic sheets are sheets made of plastic. Plastic is a synthetic polymer compound that can be freely shaped. Plastic is a material produced by polymerizing monomer raw materials through synthesis or condensation reactions. It consists of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Its main component is synthetic resin.

[0003] According to a large plastic sheet bending and shaping device with application number 202320727331.X, a servo motor, a threaded rod, an L-shaped plate, a lifting cylinder, and a pressure plate are used in combination to fix the plastic sheet on a fixed plate. A telescopic cylinder, an L-shaped block, and a pressure block are used in combination to fix the plastic sheet on a rotating plate. A drive mechanism and a rotating rod are used in combination. The output end of the stepper motor drives the main gear to rotate, causing the rotating rod to rotate, thereby driving the rotating plate to rotate to a suitable angle to bend the plastic sheet. The bending angle of the plastic sheet can be adjusted.

[0004] However, the aforementioned plastic sheet bending and shaping device has certain shortcomings. The device does not have the function of heating and softening the plastic sheet. Direct bending can easily cause the plastic sheet to break due to deformation, resulting in the scrapping of the sheet. Therefore, we propose a large-scale plastic sheet bending and shaping device.

[0012] This utility model provides a bending and shaping device for large plastic sheets, which has the following beneficial effects:

[0013] 1. This large plastic sheet bending and shaping device, through the cooperation of a blower, heating wire, and air blower, can soften the plastic sheet to be bent by energizing the heating wire and air blower during processing. After the heating wire is powered off, the air blower cools the bent part of the plastic sheet by blowing air through the blower, thus facilitating the bending process. After processing, the heating wire is powered off to stop heating, and the air blower cools the bent part by blowing air through the blower, thus facilitating the cooling and shaping of the plastic sheet.

[0023] The operating table 1 has several U-shaped grooves 18 inside. Slide grooves 19 are provided on both sides of the U-shaped grooves 18 inside the operating table 1. Springs 20 are installed inside the slide grooves 19. A slider 21 is installed inside the slide grooves 19 and above the springs 20. A rotating shaft 22 is rotatably installed inside the slider 21. A roller 23 is fixedly installed on the outside of the rotating shaft 22. The U-shaped grooves 18, slide grooves 19, springs 20, sliders 21, rotating shafts 22 and rollers 23 work together to facilitate the movement of the plastic sheet during processing. When fixing the plastic sheet, the rollers 23 can drive the sliders 21 to press down into the slide grooves 19, thereby facilitating the pressing and fixing of the plastic sheet on the operating table 1 for bending processing.

[0024] An L-shaped plate 11 is fixedly installed on one side of the top of the rotating plate 4. A first hydraulic rod 12 is fixedly installed on the top of the L-shaped plate 11. The output end of the first hydraulic rod 12 passes through the interior of the L-shaped plate 11 and is fixedly installed with a first pressure plate 13. A support plate 14 is fixedly installed on one side of the operating table 1. A top plate 15 is fixedly installed on the top of the support plate 14. Two second hydraulic rods 16 are fixedly installed on both sides of the bottom of the top plate 15. A second pressure plate 17 is fixedly installed on the output end of the second hydraulic rod 16.

The second hydraulic rods 16 and the second pressure plate 17 are used to press and fix the plastic sheet to the operating table 1.

[0025] In summary, when using this large plastic sheet bending and shaping device, the plastic sheet is placed on the roller 23 on the operating table 1. Then, one side of the sheet is moved to below the first pressure plate 13 on the rotating plate 4. Subsequently, the first hydraulic rod 12 and the second hydraulic rod 16 are simultaneously activated by the controller. The first hydraulic rod 12 drives the first pressure plate 13 to press down and fix the sheet on the rotating plate 4, while the second hydraulic rod 16 drives the second pressure plate 17 to press down and fix the sheet on the operating table 1. Finally, the air blower 7 is activated by the controller. When the heating wire 6 is energized, the air blower 7 blows air into the air duct 5. The heating wire 6 heats the blown air, which in turn heats and softens the bent part of the plastic sheet. Finally, the controller starts the servo motor 9 to drive the active bevel gear 10 to rotate. The active bevel gear 10 meshes with the driven bevel gear 8 to drive the rotating rod 3 and the rotating plate 4 to rotate, which in turn can bend the plastic sheet. After bending, the controller controls the heating wire 6 to turn off the power to stop heating, and the air blower 7 continues to cool and shape the bent part of the plastic sheet through the air duct 5.
