[0002] In the manufacturing process of massage chairs, the cutting of leather is one of the important steps.

[0003] Most massage chair leather parts are still cut manually, which has many problems. First, manual cutting is inefficient and cannot meet the needs of large-scale production. Second, the accuracy of manual cutting is difficult to guarantee. Due to individual differences among operators, the dimensions of the cut leather parts are easily inconsistent, affecting the overall quality and aesthetics of the massage chair. At the same time, the leather is cut horizontally, and the leather is soft and prone to wrinkling, which reduces the cutting accuracy. Therefore, a massage chair leather part cutting device is proposed to address the above problems. Utility Model Content

[0021] Please see Figure 1-4 This utility model provides an embodiment of a massage chair leather cutting device, including a cutting machine body 1, an electrical control cabinet installed inside the cutting machine body 1, a feeding conveyor belt 2 set at the top of the cutting machine body 1, a discharging conveyor belt 5 set at the bottom of the cutting machine body 1, an auxiliary cutting support top plate 4 installed between the feeding conveyor belt 2 and the discharging conveyor belt 5, and a cutting mechanism 3 set to the right of the auxiliary cutting support top plate 4. A support frame 7 for placing a leather roller is installed at the top left end of the cutting machine body 1. The connecting rods at the front and rear ends of the leather roller are placed in the placement groove at the top of the support frame 7. One end of the leather roll on the leather roller is transported along the feeding conveyor belt 2 to the gap between the auxiliary cutting support top plate 4 and the cutting mechanism 3. The cut leather roll falls onto the discharging conveyor belt 5.

[0022] The cutting mechanism 3 includes a translation frame 31 disposed inside the groove 30 on the right side wall of the cutting machine body 1. The right end of the translation frame 31 is fixedly connected to the telescopic end of the first hydraulic rod 32. The first hydraulic rod 32 is fixed inside the right wall of the groove 30. The upper and lower ends of the translation frame 31 are provided with sliders 33. The sides of the sliders 33 are slidably connected to the inner side walls of the limiting grooves at the upper and lower ends of the groove 30. The translation frame 31 is provided with an inner frame 34. The right end of the inner frame 34 is equipped with a second hydraulic rod 35. The telescopic end of the second hydraulic rod 35 is equipped with a cutting blade 36. The side of the cutting blade 36 is slidably connected to the inside of the limiting sleeve 37.

[0023] The auxiliary cutting support top plate 4 is equipped with a threaded rod 61. The bottom end of the threaded rod 61 is connected to the output end of the motor 62 through a coupling. The outer side of the threaded rod 61 is connected to the inside of the inner threaded sleeve 63 through a thread. The right side of the inner threaded sleeve 63 is provided with a connecting block 64. The side of the connecting block 64 is in close contact with the inner side wall of the detection groove of the auxiliary cutting support top plate 4. The right end of the connecting block 64 is equipped with a detection sensor 65.

[0024] The top of the auxiliary cutting support plate 4 has an inwardly concave arc structure, which makes it easy to install on the bottom right side of the feed conveyor belt 2.

[0025] Both ends of the feeding conveyor belt 2 and the discharging conveyor belt 5 are equipped with active drive rollers and passive drive rollers. The front end of the active drive roller is fixedly connected to the output end of the external motor 21.

[0026] The electrical control cabinet contains a frequency converter group, a controller and a hydraulic rod controller group. The frequency converter group and the hydraulic rod controller group are connected to the controller through control lines. The controller and the detection sensor 65 are connected through data lines. The frequency converter inside the frequency converter group is connected to the external motor 21 and motor 62 through circuits. The hydraulic rod controller group is connected to the first hydraulic rod 32 and the second hydraulic rod 35 through lines respectively.

[0027] When using this massage chair leather cutting device, first place the connecting rods at both ends of the leather roller into the top slot of the support frame 7 on the left side of the cutting machine body 1 to ensure that the leather roller is installed securely. Next, pull out one end of the leather roll on the leather roller and transport it along the feed conveyor belt 2 so that the leather enters the gap between the auxiliary cutting support top plate 4 and the cutting mechanism 3.

[0028] After the device is started, the external motor 21 drives the active drive rollers at both ends of the feeding conveyor belt 2 to rotate, thereby driving the feeding conveyor belt 2 to run and continuously convey the leather material to the top of the auxiliary cutting support plate 4. At the same time, the motor 62 inside the auxiliary cutting support plate 4 starts to work, and its output end drives the threaded rod 61 to rotate through the coupling. Since the outer side of the threaded rod 61 is connected to the inside of the inner threaded sleeve 63 by threads, and the connecting block 64 on the right side of the inner threaded sleeve 63 is in contact with the inner side wall of the detection groove of the auxiliary cutting support plate 4, the rotation of the inner threaded sleeve 63 is restricted, so that the inner threaded sleeve 63 can move up and down with the rotation of the threaded rod 61, thereby driving the connecting block 64 and the detection sensor 65 on the right end to move up and down, detecting the position and state of the leather material, and transmitting the detection data to the controller in the electrical control cabinet through the data line, adjusting the height of the detection sensor 65 according to the required cutting length.

[0029] When the leather is conveyed to the appropriate position, the controller receives a signal from the detection sensor 65 and sends a command to the hydraulic rod controller group. The hydraulic rod controller group controls the extension and retraction of the first hydraulic rod 32. Since the first hydraulic rod 32 is fixed inside the right wall of the groove 30, its extension end is fixedly connected to the right end of the translation frame 31, and the sliders 33 at the upper and lower ends of the translation frame 31 are slidably connected to the inner sidewalls of the upper and lower limit grooves of the groove 30. This ensures that the translation frame 31 can move smoothly laterally within the groove 30, allowing the translation frame 31 to move the inner frame 34 and the cutting blade 36 to the cutting position. When the translation frame 31 moves to the left and fits against the right side of the leather, the upper and lower ends at the cutting position are pressed down to prevent the leather from moving during cutting, increasing the practicality of the device. Subsequently, the hydraulic rod controller group controls the extension and retraction of the second hydraulic rod 35, pushing the cutting blade 36 to slide along the inside of the limit sleeve 37 to cut the leather. After cutting, the second hydraulic rod 35 retracts, causing the cutting blade 36 to reset, and the first hydraulic rod 32 retracts, causing the translation frame 31 to reset. At this time, the external motor 21 drives the discharge conveyor belt 5 to run, and transfers the cut leather material to the discharge conveyor belt 5 to complete one cutting process.
