Description

Technical Field

[0001] This utility model relates to the field of foam board cutting technology, specifically to a cutting guide device for extruded polystyrene foam boards. Background Technology

[0002] Extruded polystyrene foam board (XPS) is widely used in building insulation, cold chain packaging and other fields due to its thermal insulation, moisture resistance and pressure resistance properties. In actual construction and production, XPS boards need to be cut and processed according to specific dimensions. Currently, commonly used cutting tools include high-speed saw blades and electric heating wires. Among them, electric heating wire cutting is particularly common in small and medium-sized processing scenarios because of its dust-free cutting edge and convenient operation.

[0003] Utility model patent application number: CN202422011732.2, discloses a slitting device for foam boards with good cutting effect. It includes a cutting table, a swingable electric heating knife mounted on one side of the cutting table, several guide wheels on the side wall of the cutting table to facilitate the movement of the foam boards, support plates mounted at both ends of the cutting table, and an adjustable cutting guide plate mounted in the middle of the cutting table. The cutting guide plate has several suction holes for adsorbing the foam boards.

[0004] The aforementioned patent uses suction holes on the cutting guide plate to adsorb foam boards, thereby achieving stable fixation during cutting. However, in practical applications, the placement of the board relies entirely on manual operation and lacks a precise pre-positioning structure. Operators find it difficult to quickly and accurately align the foam board with the adsorption area of ​​the cutting guide plate, resulting in insufficient alignment accuracy between the board and the suction holes. This causes the adsorbed board to deviate from the preset cutting path, ultimately leading to cutting size errors and making it difficult to meet the requirements of high-precision processing. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a cutting guide device for extruded polystyrene foam boards to solve the problems mentioned in the background. This invention features a novel structure. By combining a housing, an air extraction hole, and a negative pressure fan, it can strongly adsorb the extruded board, preventing slippage during cutting. A transmission structure consisting of a cylinder, connecting rod, rotating plate, and sliding plate drives a limiting mechanism closer to the board, achieving precise positioning and improving the accuracy of foam board cutting by mitigating large errors in manual positioning.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a cutting and guiding device for extruded polystyrene foam board, comprising a mounting plate, an L-shaped frame mounted on one side of the mounting plate, a cutting mechanism mounted on the upper side of the L-shaped frame, a cylinder mounted on the lower side of the mounting plate, two sliding plates symmetrically arranged on the lower side of the mounting plate, a rotating plate rotatably coupled to the lower side of the mounting plate, two connecting rods arranged between the two sliding plates and the rotating plate, two connecting frames fixedly connected to the upper side of each of the two sliding plates, a limit mechanism provided on the upper side of the connecting frames, two placement shells symmetrically fixedly connected to the upper side of the mounting plate, multiple air extraction holes opened on the upper side of the placement shells, and a negative pressure fan mounted on the upper side of the mounting plate.

[0007] Furthermore, the output end of the cylinder is fixedly connected to one of the two sliding plates, and the two ends of the connecting rod are respectively hinged to the sliding plate and the rotating plate.

[0008] Furthermore, the input end of the negative pressure fan is connected to one side of the housing.

[0009] Furthermore, the cutting mechanism includes a hydraulic cylinder mounted on the upper side of the L-shaped frame, the output end of the hydraulic cylinder is fixedly connected to a mounting bracket, and a heating wire is mounted on the lower end of the mounting bracket, the heating wire being located at the center between the two placement shells.

[0010] Furthermore, the limiting mechanism includes an L-shaped plate rotatably fitted on the upper side of the connecting frame, with rotating wheels rotatably fitted at both ends of the L-shaped plate, a fixing rod fixedly connected to the upper side of the connecting frame, a tension spring fixedly connected to the upper end of the fixing rod, and a stop rod fixedly connected to the upper side of the connecting frame.

[0011] Furthermore, one end of the tension spring is fixedly connected to one side of the L-shaped plate, and the stop bar cooperates with the rotating wheel.

[0012] Furthermore, guide rails are symmetrically mounted on the lower side of the mounting plate, and guide rail sliders are slidably fitted on the guide rails. The guide rail sliders are fixedly connected to the upper side of the sliding plate.

[0013] Furthermore, two support frames are installed on the lower side of the mounting plate, and foam boards are provided on the upper side of the two placement shells. The foam boards are arranged between multiple limiting mechanisms, and the multiple rotating wheels respectively cooperate with the side of the foam boards.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model, through the structure of setting up a placement shell and an air extraction hole in conjunction with a negative pressure fan, can strongly adsorb extruded polystyrene board, preventing the board from slipping during cutting. Utilizing a transmission structure composed of a cylinder, connecting rod, rotating plate, and sliding plate, it drives the limiting mechanism to approach the board, achieving precise positioning and improving the situation of large errors in manual positioning, thereby improving the cutting accuracy of foam board.

[0016] 2. By setting up a guide rail and guide rail slider structure, this utility model ensures that the sliding plate moves smoothly, thereby ensuring the precise alignment of the limiting mechanism, reducing the cutting error caused by the sliding plate offset, and providing stable support for cutting accuracy.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1 to 5This utility model provides a technical solution: a cutting and guiding device for extruded polystyrene foam boards, including a mounting plate 1, an L-shaped frame 2 mounted on one side of the mounting plate 1, a cutting mechanism 3 mounted on the upper side of the L-shaped frame 2, a cylinder 4 mounted on the lower side of the mounting plate 1, two sliding plates 5 symmetrically arranged on the lower side of the mounting plate 1, a rotating plate 6 rotatably fitted on the lower side of the mounting plate 1, two connecting rods 7 arranged between the two sliding plates 5 and the rotating plate 6, two connecting frames 8 fixedly connected to the upper side of each of the two sliding plates 5, a limit mechanism 9 provided on the upper side of the connecting frames 8, two placement shells 10 symmetrically fixedly connected to the upper side of the mounting plate 1, multiple air extraction holes 11 opened on the upper side of the placement shells 10, and a negative pressure fan 12 mounted on the upper side of the mounting plate 1. The output end of the cylinder 4 is fixedly connected to one of the two sliding plates 5, and the two ends of the connecting rods 7 are respectively hinged to the sliding plate 5 and the rotating plate 6. The input ends of the negative pressure fan 12 are respectively connected to one side of the placement shell 10. The foam board 16 is placed on the two placement shells 10 on the upper side of the mounting plate 1. The cylinder 4 is started, and its output end drives a sliding plate 5 to move along the lower side of the mounting plate 1. The sliding plate 5 pushes the rotating plate 6 to rotate through the connecting rod 7. The rotating plate 6 then drives another sliding plate 5 to move synchronously through another connecting rod 7, so that the connecting frame 8 and the limiting mechanism 9 on the two sliding plates 5 are close to the foam board 16, and the foam board 16 is initially limited. Then the negative pressure fan 12 is started, and its input end is connected to the placement shell 10. Negative pressure is generated through the air extraction hole 11 on the placement shell 10 to quickly adsorb and fix the foam board 16, so as to avoid slippage during cutting. At the same time, it lays the foundation for subsequent precise cutting and reduces manual positioning errors.

[0025] In this embodiment, the cutting mechanism 3 includes a hydraulic cylinder 31 mounted on the upper side of the L-shaped frame 2. The output end of the hydraulic cylinder 31 is fixedly connected to a mounting bracket 32. A heating wire 33 is mounted on the lower end of the mounting bracket 32, and the heating wire 33 is located at the center between the two placement shells 10. Guide rails 13 are symmetrically mounted on the lower side of the mounting plate 1. Guide rail sliders 14 are slidably fitted on the guide rails 13, and the guide rail sliders 14 are fixedly connected to the upper side of the sliding plate 5. When the sliding plate 5 moves, it slides along the guide rail 13 on the lower side of the mounting plate 1 via the guide rail slider 14, ensuring that the sliding plate 5 moves smoothly and avoiding the impact of deviation on the alignment accuracy of the limiting mechanism 9. After the foam board 16 is fixed and limited, the hydraulic cylinder 31 in the cutting mechanism 3 is activated. The output end of the hydraulic cylinder 31 pushes the mounting frame 32 down, and the heating wire 33 at the lower end of the mounting frame 32 descends accordingly. The heating wire 33 is located at the center between the two placement shells 10, which can accurately align with the cutting position of the foam board 16. After the heating wire 33 is energized and heated, it cuts the foam board 16. The cut is dust-free, improving the cutting quality and efficiency.

[0026] In this embodiment, the limiting mechanism 9 includes an L-shaped plate 91 rotatably fitted on the upper side of the connecting frame 8. Two rotating wheels 92 are rotatably fitted at both ends of the L-shaped plate 91. A fixing rod 93 is fixedly connected to the upper side of the connecting frame 8, and a tension spring 94 is fixedly connected to the upper end of the fixing rod 93. A stop rod 95 is fixedly connected to the upper side of the connecting frame 8. One end of the tension spring 94 is fixedly connected to one side of the L-shaped plate 91, and the stop rod 95 cooperates with the rotating wheels 92. Two support frames 15 are installed on the lower side of the mounting plate 1, and foam boards 16 are provided on the upper sides of the two placement shells 10. The foam boards 16 are positioned between multiple limiting mechanisms 9, and multiple rotating wheels 92 respectively cooperate with the sides of the foam boards 16. When the limiting mechanism 9 is working, the L-shaped plate 91 is connected to the fixing rod 93 on the connecting frame 8 through the tension spring 94. The tension of the tension spring 94 causes the rotating wheel 92 at one end of the L-shaped plate 91 to first abut against one side of the foam board 16. As the cylinder 4 continues to drive, the rotating wheel 92 at the other end of the L-shaped plate 91 abuts against and fixes the other side of the foam board 16, thereby fixing the foam board 16. The stop rod 95 cooperates with the rotating wheel 92 to limit the excessive rotation of the L-shaped plate 91, ensuring that the rotating wheel 92 always stably limits the foam board 16, improving the stability during cutting and reducing the problem of uneven cut.

[0027] When using the device, first place the foam board 16 on the mounting plate 1's placement shell 10. The cylinder 4 drives one sliding plate 5 to move, and through the connecting rod 7 and rotating plate 6, the other sliding plate 5 moves synchronously and smoothly along the guide rail 13, driving the limiting mechanism 9 to approach the foam board 16. The tension spring 94 pulls the L-shaped plate 91, allowing the rotating wheel 92 to fit against the side of the foam board 16. Then, the negative pressure fan 12 is started, and the foam board 16 is adsorbed and fixed through the air extraction hole 11, achieving precise positioning of the foam board 16. Finally, the hydraulic cylinder 31 is started, pushing the mounting frame 32 and the heating wire 33 downward. The heating wire 33 is aligned with the center of the foam board 16 for cutting. Throughout the process, adsorption, synchronous limiting, and smooth transmission ensure precise cutting and reduce errors and material waste.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
