[0027] Please see Figures 1-6 The image shows a foam plastic board trimming device, which includes a positioning device 1, a trimming device 2, and a conveying device 3. The conveying device 3 is located on one side of the positioning device 1 and is used to move the trimmed foam plastic board; the trimming device 2 is located on the side of the positioning device 1 and is used to trim the foam plastic board.

[0028] The positioning device 1 includes a frame 101, a base plate 102, a motor mounting base 103, a rotary motor 104, a rotating frame 105, and a limiting component 106.

[0029] The frame 101 serves as the supporting structure for the entire equipment, providing a stable mounting base for other components and ensuring the stability of the equipment during operation. The base plate 102 is mounted on the frame 101, and the rotary motor 104 is mounted on the base plate 102 via a motor mounting base 103, with its output shaft connected to the lower end face of the rotating frame 105. The rotary motor 104 drives the rotating frame 105 to rotate, thereby adjusting the angle of the foam board and enabling trimming operations on different sides. The rotating frame 105 rotates under the drive of the rotary motor 104, and limit components 106 are respectively provided on its four sides. Four limit components 106 are provided, respectively located on the four sides of the rotating frame 105, for positioning and fixing the foam board. Each limit component 106 includes a drive cylinder 106a, a limit plate 106b, and an auxiliary guide 106c. The cylinder body of the drive cylinder 106a is connected to the rotating frame 105, and the telescopic rod is connected to the limit plate 106b. The drive cylinder 106a pushes the limit plate 106b closer to or away from the foam plastic board by the extension and retraction of the telescopic rod, thereby clamping and releasing the foam plastic board.

[0030] Under the action of the drive cylinder 106a, the limiting plate 106b limits the position of the foam plastic board, preventing it from shifting during the trimming process. A stop strip 107 is provided at the upper end of the limiting plate 106b, which is connected to the limiting plate 106b by bolts. The thickness of the limiting plate 106b is greater than the thickness of the stop strip 107, and the thickness difference between the two forms a stepped surface for placing the foam plastic board. Furthermore, the outer surface of the stop strip 107 is flush with the outer surface of the limiting plate 106b. This design allows for the positioning of foam plastic boards of different thicknesses by replacing the stop strips 107 with different heights.

[0031] Two auxiliary guide members 106c are provided, respectively located on both sides of the drive cylinder 106a and connected to the limiting plate 106b. Each auxiliary guide member 106c includes a guide base 106ca, a sliding rod 106cb, and a sliding sleeve 106cc. The bottom of the guide base 106ca is fixedly connected to the rotating frame 105. The sliding rod 106cb is connected to the guide base 106ca via the sliding sleeve 106cc, and the end of the sliding rod 106cb near the limiting plate 106b is connected to the limiting plate 106b. The function of the auxiliary guide members 106c is to provide guidance for the movement of the limiting plate 106b, ensuring its smooth and accurate movement and improving positioning accuracy.

[0032] The trimming device 2 includes a robotic arm 201, a robotic arm base 202 for fixing the robotic arm 201, and a heating wire spring cutter 203 for trimming. The robotic arm 201 is fixedly mounted on the robotic arm base 202 and is capable of multi-degree-of-freedom movement. Through preset program control, the robotic arm 201 can precisely move the heating wire spring cutter 203 to the position on the foam board that needs trimming. The heating wire spring cutter 203 is connected to the robotic arm 201. When energized, the heating wire heats up, using the high temperature to melt the edge of the foam board, thus achieving the trimming operation.

[0033] The transfer device 3 includes a conveyor belt device 301 and a support platform 302 for mounting the conveyor belt device 301. The conveyor belt device 301 is a belt conveyor. After the foam plastic board is trimmed, the conveyor belt device 301 moves it to the designated position, realizing automated material transfer and improving production efficiency.

[0034] The frame 101 is also equipped with a lifting cylinder 4 and a set of linear guide rails 5. The cylinder body of the lifting cylinder 4 is fixedly connected to the frame 101, and the telescopic rod is connected to the lower end face of the base plate 102. The lifting cylinder 4 is used to drive the lifting and lowering of the base plate 102, facilitating the adjustment of the height of the base plate 102 when replacing foam plastic boards or performing equipment maintenance. The slider on the set of linear guide rails 5 is fixedly connected to the side of the base plate 102, providing guidance for the lifting and lowering of the base plate 102 and ensuring the stability of the lifting and lowering process.

[0035] Working principle:

[0036] Before using the foam board trimming equipment, the operator needs to select a stop strip 107 of appropriate thickness according to the thickness of the foam board to be trimmed, and install it on the limiting plate 106b with bolts to ensure the accuracy of subsequent positioning. Then, the foam board to be trimmed is placed on the limiting plate 106b, specifically on the stepped surface between the stop strip 107 and the limiting plate 106b.

[0037] After the equipment is started, the drive cylinder 106a in the limiting assembly 106 begins to operate. The cylinder body of the drive cylinder 106a is fixed on the rotating frame 105, and its telescopic rod retracts, pulling the limiting plate 106b connected to it to move towards the foam board. During this process, the auxiliary guide 106c plays an important guiding role, enabling the limiting plate 106b to move smoothly along a straight line during movement, avoiding deviation, thereby tightly clamping the foam board from four directions and achieving precise positioning.

[0038] When different sides of a foam board need to be trimmed, the rotary motor 104 starts and drives the rotating frame 105 to rotate, which in turn causes the foam board fixed on the rotating frame 105 to rotate, adjusting the side that needs to be trimmed to the appropriate position. This eliminates the need for manual readjustment of the foam board's position and improves work efficiency.

[0039] In the trimming device 2, the robot arm 201 is fixed to the robot arm base 202. Under the control of a preset program, the robot arm 201 can perform multi-degree-of-freedom movements, including translation, rotation, and lifting. It precisely moves the connected heating wire spring cutter 203 to the appropriate position on the edge of the foam board according to the position of the foam board and the area requiring trimming. Once the heating wire spring cutter 203 reaches the designated position, the device is energized. The heating wire heats up rapidly, melting the material at the edge of the foam board using high temperature, thus achieving the trimming purpose. After trimming all sides of the foam board is completed, the extension rod of the drive cylinder 106a of the positioning device 1 extends, causing the limit plate 106b to release its grip on the foam board. At this time, the lifting cylinder 4 drives the base plate 102 to rise, allowing the operator to transfer the trimmed foam board to the transfer device 3. Then the conveyor belt device 301 of the transfer device 3 is started, and the conveyor belt device 301 transports the foam plastic board to the next process or the designated collection area.

[0040] In summary, this foam plastic board trimming equipment, through the coordinated work of various devices and components, achieves precise positioning, efficient trimming, and automatic transfer of foam plastic boards, thereby improving trimming efficiency and quality and reducing manual labor intensity.
