Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of memory foam processing equipment, specifically relating to a memory foam cutting and processing device. Background Technology
[0002] In the production and processing of memory foam products, it is often necessary to cut blocks of memory foam into specific shapes and sizes according to product requirements. Currently, the mainstream methods for cutting memory foam mostly rely on manually pushing the memory foam close to a fixed saw blade to complete the cutting, or using a simple mechanical structure to clamp and move the memory foam for cutting.
[0003] Manual cutting is not only labor-intensive and inefficient, but its accuracy is also easily affected by the operator's experience, making it difficult to guarantee a smooth cut and consistent shape, especially when cutting curved contours where errors are significant. Existing simple mechanical clamping devices mostly have fixed-size clamping structures, which cannot flexibly adapt to different specifications of memory foam. Uneven force during clamping can easily cause deformation of the memory foam, thus affecting the cutting quality.
[0004] Meanwhile, existing equipment typically only enables straight-line cutting in a single direction. Adjusting the cutting direction or completing curved cuts requires frequent machine stops for equipment adjustments or manual intervention, making the process cumbersome and time-consuming. Furthermore, memory foam is soft and has low density, making it prone to displacement and wrinkling during the cutting process, further reducing cutting accuracy and product yield, and failing to meet the demands of modern production for efficient, high-precision memory foam cutting. Utility Model Content
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a memory foam cutting and processing device, including a cutting table, a cutting circular saw, and a memory foam moving mechanism. The cutting circular saw is rotatably mounted on a lifting frame, which is located below the cutting table. The cutting circular saw is driven to rotate by a rotary motor, and the lifting frame is driven to move up and down by a first lifting drive mechanism. The cutting table is provided with a channel for the cutting circular saw to move up and down. The memory foam moving mechanism includes four push plates, which are located above the cutting table. The inner side of each push plate is provided with a right-angle groove. The push plates are respectively mounted on a movable plate, which is driven to move by a three-axis moving mechanism.
[0006] As a preferred embodiment of the above technical solution, the lower end of the movable plate is fixedly connected to a first longitudinal slide rail and a second longitudinal slide rail.

A first transverse slide rail is fixedly connected to the first longitudinal slider, and a second transverse slide rail is fixedly connected to the second longitudinal slider. Two first transverse sliders are mounted on the first transverse slide rail, and two second transverse sliders are mounted on the second transverse slide rail. The first and second transverse sliders correspond one-to-one with push plates, and are fixedly connected to their respective push plates. A first bidirectional lead screw is rotatably connected to the first transverse slide rail. A first forward lead screw pair and a first reverse lead screw pair are installed, and the first forward lead screw pair and the first reverse lead screw pair are respectively fixedly connected to a first transverse slider. A second bidirectional lead screw is rotatably connected to a second transverse slide rail.

The first bidirectional lead screw, the second bidirectional lead screw, and the third bidirectional lead screw are respectively fixedly connected to a rotation drive mechanism.
[0007] As a preferred embodiment of the above technical solution, a plurality of adsorption plates are provided below the movable plate. The adsorption plates are driven to move up and down by a second lifting drive mechanism installed on the movable plate. The adsorption plates have cavities inside, and the cavities are connected to a vacuum pump through pipes.

[0008] As a preferred embodiment of the above technical solution, the channel includes a longitudinal channel and a transverse channel, which are arranged perpendicularly to each other, and the circular saw is driven to rotate by a rotary drive mechanism.
[0009] As a preferred embodiment of the above technical solution, the lifting frame is fixed on the lifting plate, the first lifting drive mechanism drives the lifting plate to move up and down, the first lifting drive mechanism is installed on the rotating plate, the rotating plate is rotatably connected to the fixed plate, the rotation drive mechanism is installed on the fixed plate, and the rotation drive mechanism drives the rotating plate to rotate.
[0010] The beneficial effects of this utility model are: 1.

Combined with the negative pressure fixation of the adsorption plate, it reduces movement deformation and improves clamping stability; 2.

[0015] like Figure 1-3As shown, the memory foam cutting and processing device includes a cutting table 1, a circular saw 2, and a memory foam moving mechanism. The circular saw 2 is rotatably mounted on a lifting frame 3, which is located below the cutting table 1. The circular saw 2 is driven to rotate by a rotary motor, and the lifting frame 3 is driven to move up and down by a first lifting drive mechanism 4. The cutting table 1 has a channel for the circular saw 2 to move up and down. The memory foam moving mechanism includes four push plates 5, which are located above the cutting table 1. Each push plate 5 has a right-angle groove 6 on its inner side and is mounted on a movable plate 7. The movable plate 7 is driven to move by a three-axis moving mechanism. The first lifting drive mechanism 4 is a cylinder. The three-axis moving mechanism is a linear displacement module that moves horizontally, vertically, and vertically. A multi-axis robot can also be used instead. During operation, the memory foam to be cut is placed on the cutting table 1. The three-axis moving mechanism drives the movable plate 7 to descend, so that the memory foam is surrounded by the four push plates 5. The rotary motor drives the circular saw 2 to rotate at high speed, and the lifting frame 3 rises, so that the circular saw 2 extends out of the channel. The three-axis moving mechanism drives the movable plate 7 to move in a plane, and uses four push plates 5 to move the memory foam on the cutting table 1, thereby cutting the memory foam. When the three-axis moving mechanism drives the movable plate 7 to move in a curved path in the plane, the memory foam can be easily cut into the required shape.
[0016] Furthermore, the lower end of the movable plate 7 is fixedly connected to a first longitudinal slide rail 8 and a second longitudinal slide rail 9. A first longitudinal slider 10 and a second longitudinal slider 11 are mounted on the first longitudinal slide rail 8, and the first longitudinal slider 10 and the second longitudinal slider 11 are mounted on the second longitudinal slide rail 9. The first longitudinal slider 10 is fixedly connected to a first transverse slide rail 12, and the second longitudinal slider 11 is fixedly connected to a second transverse slide rail 13. Two first transverse sliders 14 are mounted on the first transverse slide rail 12, and two second transverse sliders 15 are mounted on the second transverse slide rail 13. The first transverse sliders 14 and 15 correspond one-to-one with the push plate 5, and are fixedly connected to their respective push plates 5. A first bidirectional lead screw 16 is rotatably connected to the first transverse slide rail 12. A first forward lead screw pair and a first reverse lead screw pair are mounted on lead screw 16. The first forward lead screw pair and the first reverse lead screw pair are respectively fixedly connected to the first transverse slider 14. A second bidirectional lead screw 17 is rotatably connected to the second transverse slide rail 13. A second forward lead screw pair and a second reverse lead screw pair are mounted on the second bidirectional lead screw 17. The second forward lead screw pair and the second reverse lead screw pair are respectively fixedly connected to the second transverse slider 15. A third bidirectional lead screw 18 is rotatably connected to the movable plate 7. A third forward lead screw pair and a third reverse lead screw pair are mounted on the third bidirectional lead screw 18. The third forward lead screw pair 18 is fixedly connected to the first transverse slide rail 12, and the third reverse lead screw pair is fixedly connected to the second transverse slide rail 13. The first bidirectional lead screw 16, the second bidirectional lead screw 17, and the third bidirectional lead screw 18 are respectively fixedly connected to a rotation drive mechanism. The rotation drive can be a rotary wheel, which adjusts the distance between the push plates 5 by manually rotating the rotary wheel, or it can be a motor, which automatically and quickly drives the rotation of each bidirectional lead screw. The third bidirectional lead screw 18 rotates, causing the first longitudinal slide rail 8 and the second longitudinal slide rail 9 to move closer or further apart. The first bidirectional lead screw 16 rotates, driving the two first transverse sliders 14 to move closer or further apart. The second bidirectional lead screw 17 rotates, driving the two second transverse sliders 15 to move closer or further apart. Through the above adjustments, the four push plates 5 are arranged into a square that matches the shape and size of the memory foam, surrounding the memory foam between the four push plates 5.
[0017] Furthermore, several adsorption plates 19 are provided below the movable plate 7. These adsorption plates 19 are driven up and down by a second lifting drive mechanism 20 mounted on the movable plate 7. Each adsorption plate 19 has an internal cavity 21, which is connected to a vacuum pump via a pipe. The lower surface of each adsorption plate 19 has several evenly spaced negative pressure holes 22, which connect to the cavity 21. The second lifting drive mechanism 20 is a cylinder. The second lifting drive mechanism drives the adsorption plates 19 downwards, using the negative pressure in the negative pressure holes 22 to adhere to the memory foam, increasing the stress points on the memory foam during movement and reducing its deformation.
[0018] Furthermore, the channel includes a longitudinal channel 23 and a transverse channel 24, which are arranged perpendicularly to each other. The circular saw 2 is driven to rotate by a rotary drive mechanism 25. The middle of the longitudinal channel 23 and the middle of the transverse channel 24 form an intersection point.
[0019] Furthermore, the lifting frame 3 is fixed on the lifting plate 26, and the first lifting drive mechanism 4 drives the lifting plate 26 to move up and down. The first lifting drive mechanism 4 is mounted on the rotating plate 27, which is rotatably connected to the fixed plate 28. The rotation drive mechanism 25 is mounted on the fixed plate 28 and drives the rotating plate 27 to rotate. The first lifting drive mechanism 4 is a cylinder, and the rotation drive mechanism 25 is a motor. The rotation drive mechanism 25 drives the rotating plate 27 to rotate, thereby adjusting the direction of the circular saw 2 so that it can extend from the longitudinal channel 23 or the transverse channel 24 for cutting.
