Description

Technical Field

[0001] This utility model relates to the field of plastic sheet processing, and in particular to a PS sheet secondary bending device. Background Technology

[0002] PS sheets, made primarily of polystyrene through extrusion, possess numerous excellent properties. They can be freely colored, resulting in a wide variety of appearances; they are odorless, tasteless, and non-toxic, making them safe for use in food packaging and other fields with extremely high hygiene and safety requirements; they do not promote bacterial growth, ensuring stability during long-term use; they are rigid, providing reliable structural support for products; they have excellent insulation properties, making them widely used for insulation protection in electronic and electrical products; and they have excellent printability, allowing for clear printing of intricate patterns and logos on their surface. These characteristics make PS sheets an important component in industries such as packaging, container equipment, household decoration, general electrical appliances, and construction.

[0003] In practical production applications, PS boards often need to be bent to meet the shape requirements of different products. However, existing bending methods have many problems. When using the traditional method of directly bending the center of the PS board, the PS board is very prone to breakage. During the center bending process, the stress at the bending part is highly concentrated, exceeding the limit that the PS board material can withstand, thus causing the board to break. This breakage not only wastes raw materials and increases production costs, but also seriously affects production efficiency. Once a PS board breaks during bending, it is necessary to use a new board for processing. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a PS board secondary bending device, which aims to improve the problem that existing PS boards are prone to breakage when the center is bent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PS board secondary bending device, comprising a support platform for supporting the bending device; a heating mechanism for heating the PS board at the bending point, installed on the top of the support platform; a bending press mechanism for bending the PS board, installed on the top of the support platform; and a limiting mechanism for positioning the PS board before bending, including a positioning mechanism and a fixing mechanism; the heating mechanism includes a first support frame, a cylinder fixedly connected to the top of the first support frame, the cylinder controlling the movement of the lower pressing frame, an upper pad fixedly connected to the bottom of the lower pressing frame, a bracket fixedly connected to the top of the support platform, a lower pad fixedly connected to the top of the bracket, and a heating tube fixedly connected to the outer wall of the bracket; the bending press mechanism includes a second support frame, a cylinder fixedly connected to the top of the second support frame, the cylinder controlling the slide plate to slide along the second support frame, an upper mold fixedly connected to the bottom of the slide plate, a push roller rotatably connected to the bottom of the upper mold, and a lower mold fixedly connected to the top of the support platform.

[0006] Furthermore, the fixing mechanism includes a cylinder three and a pressure rod. The cylinder three is fixedly installed on the top of the support frame two, and the cylinder three can control the pressure rod to move.

[0007] Furthermore, the positioning mechanism includes a motor and a worm gear, with the motor fixedly installed at the bottom of the support platform to drive the worm gear to rotate at the bottom of the support platform.

[0008] Furthermore, a sliding rod is fixedly connected to the bottom of the support platform, and a rotating shaft is rotatably connected to the bottom of the support platform.

[0009] Furthermore, a worm gear is fixedly connected to the outer wall of the rotating shaft, and the worm gear meshes with the worm.

[0010] Furthermore, a slider is slidably connected to the outer wall of the slide rod, and a rotating rod is fixedly connected to the bottom of the rotating shaft.

[0011] Furthermore, a transmission rod is rotatably connected to one side of the rotating rod, and the transmission rod is rotatably connected to the outer wall of the slider.

[0012] Furthermore, a limiting rod is fixedly connected to the top of the slider, a rotating block is rotatably connected to the top of the limiting rod, and a roller is rotatably connected inside the rotating block.

[0013] This utility model has the following beneficial effects: 1. In this utility model, firstly, the upper gasket is fixed on the bracket by the control of cylinder one, then the part of the PS board that needs to be bent is heated and softened by the heating tube, and then moved to the lower mold. The upper mold is lowered by the control of cylinder two, and the PS board is squeezed by the push roller on the upper mold, so that the PS board is bent on both sides, thereby dispersing the stress of the PS board and reducing its risk of breakage.

[0014] 2. In this utility model, the worm gear is driven to rotate by an electric motor, which in turn controls the worm wheel to rotate. The worm wheel then drives the rotating rod to rotate, which in turn drives the slider through the transmission rod. The slider then drives the limiting rod to move towards the center. With the help of the rotation of the rotating block and the roller, the PS board on the lower mold is positioned, thus improving the accuracy of bending the PS board. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1-4This utility model provides an embodiment of a PS board secondary bending device, comprising: a support platform 1 for supporting the bending device; a heating mechanism for heating the PS board at the bending point, installed on the top of the support platform 1; a bending press mechanism for bending the PS board, installed on the top of the support platform 1; and a limiting mechanism for positioning the PS board before bending, including a positioning mechanism and a fixing mechanism. The heating mechanism includes a support frame 1 2, with a cylinder 4 fixedly connected to the top of the support frame 1 2, the cylinder 4 controlling the movement of the lower pressing frame 9, an upper pad 12 fixedly connected to the bottom of the lower pressing frame 9, a bracket 10 fixedly connected to the top of the support platform 1, a lower pad 11 fixedly connected to the top of the bracket 10, and a heating tube 13 fixedly connected to the outer wall of the bracket 10. The bending press mechanism includes a support frame 2 3, with a cylinder 2 5 fixedly connected to the top of the support frame 2 3, the cylinder 2 5 controlling the slide plate 14 to slide along the support frame 2 3, an upper mold 8 fixedly connected to the bottom of the slide plate 14, a push roller 16 rotatably connected to the bottom of the upper mold 8, and a lower mold 7 fixedly connected to the top of the support platform 1. Specifically, when bending the PS board, the PS board should first be placed stably on the top of the bracket 10 to ensure that it is neatly arranged. Then, through the precise control of cylinder 4, the lower pressure frame 9 is slowly pressed down to firmly hold the PS board in place, preventing it from shifting during subsequent operations. During this process, the lower pad 11 and upper pad 12 installed on the bracket 10 and the lower pressure frame 9, respectively, play a crucial protective role, effectively preventing scratches on the surface of the PS board due to friction. After the PS board is firmly fixed, the heating tubes 13 evenly distributed on both sides of the bracket 10 can be used to evenly heat the part of the PS board to be bent, ensuring that it reaches the appropriate bending temperature.

[0019] After heating, the heated PS board is carefully placed on top of the lower mold 7, ensuring its accurate position. Next, driven by the motor 18, the worm 19 begins to rotate. The rotation of the worm 19 drives the worm wheel 27 to rotate synchronously. The worm wheel 27, through the rotating shaft 21 connected to it, further drives the rotating rod 20 to rotate. The rotating rod 20, through the transmission rod 22, pulls the slider 23 to slide smoothly on the slide rod 24. During the movement of the slider 23, the limit rods 17 on both sides can be controlled to move towards the center position synchronously. The rotating block 25 on the limit rod 17 also rotates accordingly to match the edges and corners of the PS board, ensuring that the PS board is accurately centered on the lower mold 7.

[0020] After positioning, the pressure rod 15 is pressed against the PS board by the control of cylinder 3 6 to ensure its stability during bending. Finally, cylinder 2 5 drives the slide plate 14, which drives the upper mold 8 to slide down the guide rail. With the rotation of the bottom push roller 16, the upper mold 8 precisely bends both sides of the PS board, thus completing the entire bending process. The entire process ensures the high efficiency and precision of PS board bending through the coordinated cooperation of various components.

[0021] Working principle: When bending the PS board, the PS board can be placed on top of the bracket 10, and then the lower pressure frame 9 is controlled by cylinder 4 to press the PS board. At the same time, the lower shims 11 and upper shims 12 on the bracket 10 and the lower pressure frame 9 prevent the PS board from being scratched. After the PS board is fixed, the heating tubes 13 on both sides of the bracket 10 can heat the area to be bent. Then the heated PS board is placed on top of the lower mold 7, and then the worm gear 19 is driven by the motor 18, which drives the worm wheel 27 to rotate. The worm wheel 27 will then drive the rotating rod 20 through the rotating shaft 21. The rotating rod 20 pulls the slider 23 through the transmission rod 22, causing the slider 23 to slide on the sliding rod 24. When the slider 23 moves, the limit rods 17 on both sides can be controlled to move towards the center. Then, the rotating block 25 on the limit rod 17 rotates to cooperate with the corner of the PS plate, so that the PS plate is centered on the lower mold 7. Then, the cylinder 3 6 controls the pressure rod 15 to press the PS plate. The cylinder 2 5 can drive the slide plate 14, so that the slide plate 14 drives the upper mold 8 to slide down. Thus, the upper mold 8 bends the two sides of the PS plate through the rotation of the bottom push roller 16.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
