Description

Technical Field

[0001] This application relates to the field of foam processing, and in particular to a foam cutting structure. Background Technology

[0002] In the production of foam, it is often necessary to cut continuous foam material into specific lengths for subsequent processing and use. Currently, foam cutting is typically done manually or with simple machinery, resulting in low efficiency, low cutting accuracy, and high labor intensity. Furthermore, traditional cutting equipment often lacks automated conveying and positioning functions, causing the foam to easily shift or deform during cutting, affecting product quality. Therefore, there is an urgent need for a foam cutting structure that is highly automated, has high cutting accuracy, and is easy to operate. Utility Model Content

[0003] To address the issues of low efficiency, low cutting accuracy, and high labor intensity that typically arise from manual labor or simple machinery used for cutting foam, this application provides a foam cutting structure.

[0004] The foam cotton slit structure provided in this application adopts the following technical solution:

[0005] The device includes a support bed and foam. Guide rails are installed on both sides of the upper part of the support bed. Slider blocks are provided on the guide rails. Two sliders are connected by a crossbeam. A pneumatic cylinder is installed on the crossbeam. The output end of the pneumatic cylinder is provided with a gripper. Support seats are installed at the four inner corners of the support bed. Rotating shafts are installed on the support seats. Synchronous pulleys are installed on the rotating shafts. Synchronous pulleys on the same side are connected by a synchronous belt drive. An extension plate is installed at the lower part of the crossbeam. The extension plate is connected to the synchronous belt.

[0006] By adopting the above technical solution, the crossbeam is moved by the synchronous belt, so that the gripper is positioned at the cut-off position of the foam. The pneumatic cylinder drives the gripper to hold the foam, and then the crossbeam continues to move to the cut-off point.

[0007] Preferably, a first drive motor is installed at one end of the rotating shaft located at the same end as the support bed, the output end of the first drive motor is connected to one end of the rotating shaft, and the first drive motor is connected to the support base.

[0008] By adopting the above technical solution, the first drive motor is used to drive the rotating shaft and the synchronous belt.

[0009] Preferably, the inner side of the support bed is provided with a liftable placement platform, and the foam is located on the placement platform.

[0010] By adopting the above technical solution, it is easy to adjust the height of the foam to adapt to the cutting operation.

[0011] Preferably, a mounting plate is provided at the middle of the inner side of the support bed, and a stud is rotatably mounted on the mounting plate, with the upper end of the stud rotatably connected to the middle of the placement platform.

[0012] By adopting the above technical solution, the driven wheel is rotated by the transmission belt, thereby causing the stud to rotate and rise and fall, adjusting the height of the placement platform.

[0013] Preferably, a driven wheel is mounted on the mounting plate, the inner side of the driven wheel is threadedly connected to a threaded cylinder and a stud, and the side of the driven wheel is connected to a driving wheel via a transmission belt.

[0014] By adopting the above technical solution, the driving wheel is driven to rotate, and the driven wheel is driven to rotate through the transmission belt, thereby causing the stud to rotate and rise and fall.

[0015] Preferably, a second drive motor is connected to the middle of the drive wheel, the output end of the second drive motor is connected to the drive wheel, and the second drive motor is connected to the mounting plate.

[0016] By adopting the above technical solution, the second drive motor is used to drive the active wheel and the passive wheel to rotate, thereby controlling the lifting and lowering of the stud.

[0017] Preferably, a conveyor frame is installed at one end of the support bed, a conveyor roller is installed on the conveyor frame, a flattening plate is installed on the conveyor frame and located on the conveyor roller, and a push cylinder is installed on the conveyor frame, with the output end of the push cylinder connected to the middle of the flattening plate.

[0018] By adopting the above technical solutions, the conveyor frame and flat pressure plate ensure that the foam cotton remains flat during the conveying process, avoiding displacement or deformation.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application uses a pneumatic cylinder to push the gripper downwards and firmly clamp the foam below it. After the gripper is firmly clamped, the first drive motor starts again, drives the synchronous belt, and moves the entire crossbeam and the clamped foam together in the cutting direction. This straightens and tightens the foam, eliminates any loose parts inside, and ensures that the foam is taut at the moment of cutting, thereby obtaining a neat and vertical cut surface. At this time, the cutting action can be completed.

[0021] 2. In this application, when the foam passes through the conveyor roller, the push cylinder drives the flat plate to press the foam downward to ensure that the foam enters the cutting area flat. The foam is then conveyed to the support bed's placement table by the conveyor roller on the conveyor frame. The push cylinder drives the flat plate to flatten the foam and avoid wrinkles.

[0028] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0029] This application discloses a foam cotton cutting structure. Please refer to the following embodiments. Figures 1 to 3The system includes a support bed 1 and foam 3. Guide rails 7 are installed on both upper sides of the support bed 1. Slider blocks 8 are mounted on the guide rails 7, and two sliders 8 are connected by a crossbeam 9. A pneumatic cylinder 10 is mounted on the crossbeam 9, and a gripper 11 is provided at the output end of the pneumatic cylinder 10. Support seats 12 are installed at the four inner corners of the support bed 1, and rotating shafts 13 are mounted on the support seats 12. Synchronous pulleys 14 are mounted on the rotating shafts 13, and synchronous pulleys 14 located on the same side are connected by a synchronous belt 15. An extension plate 1 is installed at the lower part of the crossbeam 9. 6. The extension plate 16 is connected to the synchronous belt 15. The first drive motor 17 is installed at one end of the rotating shaft 13 located at the same end of the support bed 1. The output end of the first drive motor 17 is connected to one end of the rotating shaft 13. The first drive motor 17 is connected to the support base 12. When the first drive motor 17 is started, it drives the crossbeam 9 to move through the synchronous belt 15, so that the gripper 11 is positioned at the cutting position of the foam 3. The pneumatic cylinder 10 drives the gripper 11 to clamp the foam 3. Then the crossbeam 9 continues to move to the cutting point to complete the cutting operation.

[0030] Please refer to Figure 1 , Figure 4 and Figure 5 The inner side of the support bed 1 is provided with a liftable placement platform 18, on which the foam 3 is located. A mounting plate 20 is located in the middle of the inner side of the support bed 1. A stud 19 is rotatably mounted on the mounting plate 20, and the upper end of the stud 19 is rotatably connected to the middle of the placement platform 18. A driven wheel 21 is mounted on the mounting plate 20. The inner side of the driven wheel 21 is threadedly connected to the stud 19 via a threaded sleeve. A driving wheel 22 is connected to the side of the driven wheel 21 via a transmission belt. A second drive motor 23 is connected to the middle of the driving wheel 22. The output end of the second drive motor 23 is connected to the drive wheel 22. The second drive motor 23 is connected to the mounting plate 20. The side of the driven wheel 21 is connected to the drive wheel 22 via a transmission belt. The middle of the drive wheel 22 is connected to the second drive motor 23. The output end of the second drive motor 23 is connected to the drive wheel 22 via a keyway. When the second drive motor 23 starts, it drives the drive wheel 22 to rotate, which drives the driven wheel 21 to rotate via the transmission belt, thereby causing the stud 19 to rotate and rise and fall, adjusting the height of the placement platform 18.

[0031] Please refer to Figure 1 and Figure 2A conveyor frame 2 is installed at one end of the support bed 1. A conveyor roller 4 is installed on the conveyor frame 2. A flat pressure plate 5 is installed on the conveyor frame 2 and on the conveyor roller 4. A push cylinder 6 is installed on the conveyor frame 2. The output end of the push cylinder 6 is connected to the middle of the flat pressure plate 5. When the foam 3 passes through the conveyor roller 4, the push cylinder 6 drives the flat pressure plate 5 to press the foam 3 downward, ensuring that the foam 3 enters the cutting area flat. The foam 3 is conveyed to the placement platform 18 of the support bed 1 through the conveyor roller 4 on the conveyor frame 2. The push cylinder 6 drives the flat pressure plate 5 to flatten the foam 3 and avoid wrinkles.

[0032] The implementation principle of the foam cutting structure in this application embodiment is as follows: The continuous foam roll to be cut is first placed on the conveyor frame 2. Through the rotation of the conveyor roller 4, the foam is continuously and steadily fed into the working area of ​​the support bed 1 and laid flat on the placement table 18 for leveling and positioning. At the same time as the foam enters, the push cylinder 6 starts to work, and its output end pushes the leveling plate 5 downward. The leveling plate 5 tightly presses the foam that may wrinkle or curl onto the conveyor roller or placement table 18. The first drive motor 17 drives the rotating shaft 13 connected to it to rotate, and the synchronous wheel 14 on the shaft rotates accordingly. Through the transmission of the synchronous belt 15, since the crossbeam 9 is fixed to the synchronous belt 15 through its lower extension plate 16, the crossbeam 9 is cut off. The motion of the synchronous belt 15 is directly converted into the linear motion of the crossbeam 9. The sliders 8 at both ends of the crossbeam 9 slide on the guide rail 7, ensuring the stability and precision of the movement process without deviation or jamming. At this time, the pneumatic cylinder 10 is activated, pushing the gripper 11 to move downward and firmly clamp the foam below it. After the clamping is firm, the first drive motor 17 starts again, driving the synchronous belt and moving the entire crossbeam 9 and the clamped foam together towards the cutting direction, which is usually the direction of the cutting blade. The movement is not shown in the figure. The foam is straightened and tightened, eliminating the loose parts inside, ensuring that the foam is in a taut state at the moment of cutting, thereby obtaining a neat and vertical cut surface. At this time, the complete cutting action can be performed.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
