Description

Technical Field

[0001] This utility model relates to the field of cutting mechanism technology, and in particular to a foam board positioning and cutting mechanism. Background Technology

[0002] Foam board is a lightweight porous material made of polymer resin as the matrix through physical or chemical foaming processes. It has the characteristics of low density, high cushioning, heat insulation and sound insulation. As a lightweight and multifunctional material, foam board is irreplaceable in fields such as building energy conservation and precision packaging. Currently, foam boards usually need to be cut into appropriate sizes before use. Since foam board is made of polymer resin as the matrix, it will melt when heated. Therefore, the cutting device usually uses heating wire to cut it to make the cut surface flat and smooth.

[0003] In existing technologies, the cutting of foam boards typically relies on operators manually holding the boards. Because foam boards are lightweight, have a smooth surface, and lack stable support points, manual operation requires operators to rely solely on visual judgment and alignment. This is highly susceptible to interference from factors such as individual eyesight, hand stability, and operating experience, making it difficult to accurately position the foam board on the predetermined cutting line. This results in uneven cut edges, significant dimensional deviations, and low overall cutting accuracy. Furthermore, manual operation means that each cutting action requires the operator to gradually advance and repeatedly confirm, making the entire process time-consuming and laborious, extending the cutting time for a single foam board and leading to low work efficiency. Therefore, an improved foam board positioning and cutting mechanism is needed to solve these problems. Utility Model Content

[0025] Please see Figure 5 - Figure 6In this embodiment, the lifting assembly includes a base 313, which is disposed at the bottom of the workbench 1. A second semicircular block 31 is fixedly connected to the base 313, and a second bracket 35 is rotatably connected inside the second semicircular block 31.

[0026] During operation, the hydraulic telescopic rod 311 is activated, causing the second support 35 to rotate crosswise on the first support 32. The first roller 37 moves within the groove of the first limiting frame 36, and the second roller 39 moves within the groove of the second limiting frame 38, reducing friction and improving the lifting stability of the worktable 1. The height of the worktable 1 is adjusted by the cross angle between the second support 35 and the first support 32, improving the adaptability of the device. When cutting foam board, the connecting plate 213 is pushed upwards... Spring 212 is compressed, causing pressure plate 211 to move upward. At this time, foam boards of different specifications are placed between rubber pad 29 and support plate 222. Rotating worm gear 22 causes positioning plate 27 to slide inside worktable 1, bringing both ends of the foam board into contact with rubber pad 29 and support plate 222 respectively, thus positioning the foam board and limiting it between support plate 222 and positioning plate 27. Rubber pad 29 prevents damage to the foam board. After positioning the foam board, the connecting... When plate 213 is released, the compressed spring 212 drives the pressure plate 211 to press the positioned foam board, thus fixing it in place. Then, the first motor 214 is started, driving the first threaded rod 215 to rotate inside the worktable 1. A movable bracket 216 is threaded onto the outside of the first threaded rod 215, allowing adjustment of the position of the heating wire 221. This facilitates adjustment for cutting the foam board as needed. After adjustment, the first motor 214 is stopped, and then the electric heater 223 is started, causing the heating wire to rotate. Heating is performed at 221, and then the second motor 217 is started, which drives the second threaded rod 218 to rotate inside the moving bracket 216. The rod is threadedly connected to the outside of the second threaded rod 218 through the slider 219, which drives the electric heating wire 221 to move downward, cutting the foam board. After cutting, the electric heating wire 221 is driven to rise, resetting the electric heating wire 221 and turning off the electric heater 223, thus completing the cutting of the foam board, improving the cutting accuracy and the practicality of the device.

[0027] Through the above steps, foam boards of different specifications are placed between the rubber pad 29 and the support plate 222, and the positioning plate 27 slides inside the worktable 1 to position the foam boards. The positioning foam boards are then pressed down by the pressure plate 211 to fix them in place. The position of the electric heating wire 221 is adjusted according to the required cutting position of the foam boards, so that the electric heating wire 221 moves downward through the slider 219 to cut the foam boards. This improves the cutting accuracy of the foam boards and solves the problem of uneven cutting edges, large dimensional deviations, low overall cutting accuracy, and reduced work efficiency caused by relying on manual operation.
