[0027] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0028] Combination Figure 1-4 As shown, this embodiment of the present disclosure provides a foam pad cutting device, comprising a frame 100, on which a conveyor belt 200 is arranged laterally, the conveyor belt 200 being a breathable annular belt structure; an air extraction chamber 300 disposed inside the annularity of the conveyor belt 200, with the upper part of the air extraction chamber 300 closely attached to the upper inner sidewall of the conveyor belt 200; and a cutting frame 400 slidably disposed on the upper part of the frame 100, with a cutting slide 401 disposed on the cutting frame 400, and a cutting device slidably disposed on the cutting slide 401.

[0029] Using the foam pad cutting device provided in this embodiment, the frame 100 can support the conveyor belt 200, which can transport the foam pad. The foam pad can be laid flat on the conveyor belt 200 and continuously transported. The suction chamber 300 is set inside the annular space of the conveyor belt 200 and its upper part is close to the inner side wall of the conveyor belt 200. Under the action of negative pressure, the foam pad can be adsorbed on the surface of the conveyor belt 200 to prevent it from shifting during the transport process. It can also keep the foam pad stable during the cutting process and improve the cutting accuracy. The cutting frame 400 is slidably set on the upper part of the frame 100 and can move back and forth along the conveying direction of the conveyor belt 200. The cutting slide 401 set on the cutting frame 400 is horizontally set on the upper part of the conveyor belt 200. The cutting device on the cutting slide 401 can move in the direction perpendicular to the moving direction of the conveyor belt 200, thereby realizing the horizontal cutting of the foam pad, ensuring that the cutting line is perpendicular to the conveying direction. The cutting device moves up and down on the cutting slide 401, thereby realizing the precise cutting of the foam pad.

[0030] Optionally, slide rails 101 are provided on both sides of the upper part of the frame 100, the cutting frame 400 is slidably disposed on the slide rails 101, a pressure roller 402 is provided in the middle of the cutting frame 400, and the pressure roller 402 is arranged laterally on the upper part of the conveyor belt 200.

[0031] In this way, the slide rails 101 on both sides of the upper part of the frame 100 can provide stable guidance for the cutting frame 400, so that it can move back and forth smoothly along the conveying direction; the cutting frame 400 is rotatably equipped with pressure rollers 402, which are laterally arranged on the upper part of the conveyor belt 200. They can initially flatten and fix the foam pad before it enters the cutting area, so that the foam pad can remain flat during the cutting process and avoid cutting deviation caused by local lifting or loosening.

[0032] Optionally, the cutting frame 400 is provided with a vertical slide 403, and a sliding block 404 is slidably disposed inside the vertical slide 403. The pressure roller 402 is rotatably disposed on the sliding block 404. A positioning screw 405 is threadedly connected to the upper part of the vertical slide 403, and the lower end of the positioning screw 405 is rotatably connected to the sliding block 404.

[0033] In this way, the vertical slide 403 on the cutting frame 400 cooperates with the sliding block 404. The sliding block 404 can slide up and down in the vertical slide 403. The height position of the sliding block 404 can be adjusted by rotating the positioning screw 405, thereby precisely controlling the distance between the pressure roller 402 and the conveyor belt 200, adapting to foam pads of different thicknesses, ensuring moderate pressing force, avoiding excessive pressure that causes material deformation, and preventing insufficient pressure that causes insecure fixing. It maintains a stable and flat state during the cutting process, further improving cutting accuracy and work efficiency.

[0034] Optionally, the air extraction chamber 300 is a rectangular box-shaped structure with an opening at the top. Several support rollers 301 are arranged side by side at the top of the air extraction chamber 300, and an air extraction pipe 302 is arranged at the bottom of the air extraction chamber 300.

[0035] In this way, the suction pipe 302 at the bottom of the suction chamber 300 can be connected to an external vacuum device, creating a negative pressure environment inside the suction chamber 300. This causes the foam pad to be evenly adsorbed on the surface of the conveyor belt 200, preventing displacement during conveying. Furthermore, it generates a downward adsorption force on the foam pad during cutting, effectively suppressing material movement and warping caused by vibration or airflow disturbance during the cutting process. The support rollers 301 are arranged side-by-side on the upper part of the suction chamber 300, supporting both the conveyor belt 200 and the foam pad while reducing running resistance, making the conveying process smoother and more stable. The equidistant arrangement of the support rollers 301 effectively disperses the pressure on the foam pad, avoiding localized stress concentration that could lead to deformation, ensuring that the surface flatness of the material remains unaffected during cutting.

[0036] Optionally, a support baffle 303 is provided between the support rollers 301 on the upper part of the air extraction chamber 300.

[0037] In this way, the support baffles 303 set between the support rollers 301 at the top of the suction chamber 300 can effectively support the gap between the support rollers 301 and reduce the span between adjacent support rollers 301, preventing the conveyor belt 200 and the foam pad from getting stuck in the gap due to local sinking during the conveying process. It can also reduce the gap between the support baffles 303 and the support rollers 301. In this way, when the suction chamber 300 is suctioning, the suction force can be more concentrated, which can increase the adsorption effect on the foam pad on the surface of the conveyor belt 200 and further improve the stability of the material in high-speed conveying and dynamic cutting.

[0038] Optionally, a partition 304 is provided at the lower part of the support baffle 303. The partition 304 is connected to the inner side of the air extraction chamber 300 at the lower part of the support baffle 303, and the support baffle 303 separates the air extraction chamber 300.

[0039] In this way, the partition 304 located at the lower part of the support baffle 303 divides the interior of the suction chamber 300 into multiple independent negative pressure chambers, realizing zoned suction control. The suction strength of different areas can be adjusted according to actual needs, avoiding energy waste or uneven adsorption caused by overall suction. Vacuum suction of the corresponding section is activated according to the width of the foam pad or the conveying position, effectively improving energy utilization efficiency and reducing operating noise.

[0040] Optionally, each of the plurality of partitions 304 is connected to an exhaust pipe 302.

[0041] In this way, each of the individual negative pressure chambers formed by the multiple partitions 304 is connected to an air extraction pipe 302, which allows for independent air extraction control of each negative pressure chamber and enables the adjustment of suction distribution as needed.

[0042] Optionally, multiple extraction pipes 302 are connected to a connecting pipe 305, and each extraction pipe 302 is equipped with an air valve 306.

[0043] In this way, multiple suction pipes 302 can be connected into a unified air circuit system through the connecting pipe, which can be easily connected to the suction pump. The air valve 306 on the suction pipe 302 can accurately control the opening and closing of each negative pressure chamber and the suction force, so as to achieve on-demand air supply and segmented adjustment, further optimizing the adsorption uniformity and energy efficiency ratio.

[0044] Optionally, a negative pressure chamber 307 is formed between the partitions 304, and an inclined plate 308 is provided at the bottom of the negative pressure chamber 307. The inclined plate 308 is inclined upward from one end connected to the air extraction pipe 302.

[0045] In this way, the inclined plate 308 at the bottom of the negative pressure chamber 307 formed by the partition 304 tilts upward from the end connected to the extraction pipe 302, which can guide the airflow smoothly into the extraction pipe 302, reduce eddies and resistance, and improve extraction efficiency. At the same time, the inclined plate 308 structure helps to prevent dust or debris from accumulating at the bottom of the negative pressure chamber 307, keeping the interior clean and reducing maintenance frequency.

[0046] Optionally, a sliding frame 406 is vertically slidably mounted on the cutting device, a cutting blade 407 is mounted on the side of the sliding frame 406, and a lifting screw 408 is vertically mounted inside the cutting device. The sliding frame 406 and the lifting screw 408 are threadedly connected.

[0047] In this way, the vertically sliding frame 406 within the cutting device achieves precise vertical movement via the lifting screw 408. Rotating the lifting screw 408 drives the sliding frame 406 to smoothly rise and fall along the cutting device, thereby synchronously adjusting the height of the side cutting blade 407 to adapt to the cutting needs of foam pads of different thicknesses. The lifting screw 408 is driven by a servo motor and, in conjunction with a position sensor, achieves closed-loop control, ensuring precise and controllable cutting depth and improving processing accuracy and consistency.

Individual components and functions are optional unless explicitly required, and the order of operation may vary. Parts and features of some embodiments may be included or substituted for parts and features of other embodiments.
