Description

Technical Field

[0001] This utility model relates to the field of artificial leather processing technology, and in particular to a punching machine for artificial leather processing. Background Technology

[0002] Synthetic leather, also known as artificial leather, is a composite material that uses polymer materials to simulate the structure and properties of natural leather. Its core process involves coating or impregnating polymers such as polyvinyl chloride (PVC) and polyurethane (PU) onto the surface of a base fabric (non-woven fabric, knitted fabric), followed by processes such as embossing and surface treatment to create a leather-like texture.

[0003] Chinese patent CN221659511U discloses a high-speed synchronous punching machine for automotive artificial leather interior panels. This machine utilizes mechanical drive and an auxiliary sliding assembly to stabilize the positioning component at a designated position, facilitating rapid positioning of the artificial leather interior panels. The easily detachable punching cutters allow for controlled punching from multiple angles, facilitating the replacement of different sized cutters and achieving smooth, high-speed synchronous punching. While the mechanical drive makes the machine simple and easy to operate, the spacing between the multiple punching cutters cannot be changed, making it inconvenient to accommodate other sizes. When producing different hole patterns, the machine must be stopped to replace the entire set of cutters, increasing changeover time by 30%-50%. This increases the marginal cost of small-batch, multi-variety orders, weakening market competitiveness. Therefore, this invention proposes a punching machine for artificial leather processing to address these issues. Utility Model Content

[0022] like Figure 1-4 As shown, the present invention proposes a perforating machine for processing artificial leather, comprising a base 1, a frame 2, and a receiving hopper 9. The base 1 is hollow inside, the frame 2 is connected to the top of the base 1, and the receiving hopper 9 is disposed inside the base 1. The invention is characterized by further comprising a hydraulic cylinder 3, a moving frame 4, multiple punching blades 5, and a punching plate 6. The hydraulic cylinder 3 is disposed at the top of the frame 2, with its telescopic rod pointing vertically downwards. The moving frame 4 is connected to the bottom of the hydraulic cylinder 3. The multiple punching blades 5 are spaced apart below the moving frame 4. The top of the base 1 has an installation groove, and the punching plate 6 is detachably connected to the installation groove. The punching plate 6 has punching slots that are adapted to the size of the multiple punching blades 5. The moving frame 4 has an adjustment component inside for adjusting the distance between the multiple punching blades 5.

[0023] In this invention, a hydraulic cylinder 3 drives a moving frame 4 to move up and down continuously to punch holes in the passing leather. The prior art mentions that the operator controls the drive motor via a microcontroller. The output shaft of the drive motor rotates, causing the lead screw to rotate, which in turn causes the internal threaded cylinder to move the positioning plate back and forth along the guide post. The positioning plate slides smoothly via a slide rail, allowing it to move steadily to the desired position on the artificial leather interior panel. The operator uses the side of the artificial leather interior panel to be punched to press against the positioning plate, achieving stable positioning. When punching different types of artificial leather, the spacing between multiple punching blades 5 is adjusted using an adjusting component. Different punching plates 6 are then used to replace the punched leather waste into the receiving hopper.

[0024] In an optional embodiment, the front and rear walls of the mounting groove are connected to support plates, and the perforated plate 6 is located above the two support plates.

[0025] In an optional embodiment, a buckle 8 is provided on the left side of the stand 2, and a fixing plate 61 is connected to the left side of the perforated plate 6 and extends to the left side of the base 1. A fixing hole is provided on the fixing plate 61, and the size of the fixing rod of the buckle 8 is adapted to the size of the fixing hole.

[0026] It should be noted that when the perforated plate 6 is pulled out from the left side of the base 1 for replacement, the fixing plate 61 is fixed by the clip 8 to prevent the perforated plate 6 from moving in the mounting groove, which would cause the punch 5 to fail to enter the punching groove during punching, thus damaging the perforated plate 6 and the punch 5.

[0027] In an optional embodiment, the adjustment assembly includes a threaded rod 71, a movable plate 72, multiple movable frames 73, and a limiting rod 74. The threaded rod 71 is rotatably connected to the bottom wall of the movable frame 4 and extends above it. The movable plate 72 is slidably connected between the left and right walls of the movable frame 4 and is threadedly connected to the threaded rod 71. The limiting rod 74 is fixedly connected between the left and right walls of the movable frame 4. The multiple movable frames 73 are slidably sleeved on the limiting rod 74. The movable plate 72 has multiple sliding grooves. Each of the multiple movable frames 73 is connected to a sliding rod 75. The multiple sliding rods 75 are slidably connected to the inner walls of the multiple sliding grooves respectively.

[0028] In an optional embodiment, a plurality of movable frames 73 extend through and below the movable frame 4, and the bottom end of the movable frame 4 is provided with a sliding window adapted to its size, and a plurality of punching cutters 5 are threadedly connected to the bottom end of the plurality of movable frames 73 respectively.

[0029] It should be noted that when adjusting the spacing between multiple punching cutters 5, turning the threaded rod 71 drives the moving plate 72 to move up and down. Since the multiple sliding grooves on the moving plate 72 will drive the multiple sliding rods 75 to disperse or move closer together, the multiple moving frames 73 will slide on the limiting rod 74, and the spacing between them will always be equal.

[0030] In an optional embodiment, the left and right walls of the platform 2 are connected with limit strips, and the left and right walls of the movable frame 4 are provided with sliding grooves, with the inner walls respectively slidably connected to the two limit strips.

[0031] It should be noted that when the moving box 4 moves up and down, it will slide along the two limit bars to prevent it from deviating during the slide.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
