Description

Technical Field

[0001] The utility model relates to the technical field of clamping and tensioning mechanisms, in particular to a sheet clamping and tensioning mechanism for a laser cutting machine. Background Technique

[0002] A laser cutting machine emits laser from a laser, and through an optical path system, the laser is focused into a laser beam with a high power density. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, a high-pressure gas coaxial with the beam blows away the melted or vaporized metal. A sheet refers to a sheet with resin as the main component, plasticizer, filler, lubricant, coloring agent and other additives as auxiliary components, and has a certain toughness and can form a curved surface.

[0003] An existing sheet clamping and tensioning mechanism for a laser cutting machine (Publication No.: CN220921285U) has at least the following drawbacks: This device is convenient for clamping and straightening curved sheets. Since the sheets are cut from a sheet roll, the two ends of the cut sheets will converge inward, and the whole sheet will be in a curved shape, which is not conducive to installing the two ends of the sheet on the clamping device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to provide a sheet clamping and tensioning mechanism for a laser cutting machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0024] Refer to Figures 1 - 5, A sheet clamping and tensioning mechanism for a laser cutting machine, including a clamping frame 1, a cutting device 6 and a roller frame 8. Clamping grooves 101 are respectively formed on both sides of the clamping frame 1, and a first pressing frame 2 and a second pressing frame 3 are respectively installed inside the clamping grooves 101. The cutting device 6 includes a cutter 601 and an electric push rod 602. The electric push rod 602 is fixedly connected to the top of the clamping frame 1, and the telescopic end of the electric push rod 602 penetrates through the clamping frame 1 and is fixedly connected to the top of the cutter 601. The cutter 601 is located on one side of the bottom of the clamping frame 1. The cutting device 6 is located between the clamping frame 1 and the roller frame 8. The top of the roller frame 8 is movably connected to a sheet cylinder 7, and the cutting device 6 is installed on one side of the sheet cylinder 7.

[0025] During use, a roller frame 8 is installed on one side of the laser cutting device 9, the sheet cylinder 7 is placed on the roller frame 8, and the sheet is pressed and fixed in position by the first pressing frame 2 and the second pressing frame 3, facilitating the laser cutting device 9 to cut the sheet. After the sheet is cut, the operator activates the cutting device 6 on one side of the clamping frame 1, and the electric push rod 602 drives the cutter 601 to cut off the tail of the sheet, facilitating the operator to pick up the cut sheet and also facilitating the cutting of some sheets, avoiding the influence of pre-cutting on the winding of the sheet and affecting the installation.

[0026] In this embodiment, the first pressing frame 2 and the second pressing frame 3 have the same structure. The first pressing frame 2 includes a pressing plate 201 and a cylinder 202. The cylinder 202 is fixedly connected to the top of the clamping frame 1, and one end of the cylinder 202 penetrates through the clamping frame 1 and is fixedly connected to the pressing plate 201.

[0027] During use, the operator pulls the sheet through the pressing roller group 5, places it in the clamping groove 101, and activates the first pressing frame 2 and the second pressing frame 3. The cylinder 202 drives the pressing plate 201 to descend to squeeze and fix the sheet.

[0028] In this embodiment, a beveled push plate 4 is provided on one side of the pressing plate 201. Both ends of the beveled push plate 4 are fixedly connected to both sides inside the clamping frame 1. A laser cutting device 9 is provided at the bottom of the clamping frame 1, and the clamping frame 1 is fixedly connected to the top of the laser cutting device 9.

[0029] During use, the beveled push plate 4 is inclined. When the operator pulls the sheet, the tail of the sheet is scraped by the beveled push plate, preventing the two sides of the sheet from bulging and gathering, making the sheet lie flat on the clamping frame 1 as a whole, facilitating the clamping and fixing by the first pressing frame 2 and the second pressing frame 3.

[0030] In this embodiment, a pressing roller group 5 is provided on one side of the beveled push plate 4. The pressing roller group 5 is respectively movably connected to the inner sides of the laser cutting device 9 and the roller frame 8. The roller frame 8 is attached to one side of the laser cutting device 9, and a waste box 801 is provided on one side of the laser cutting device 9.

[0031] During use, the pressing roller group 5 is composed of a number of roller rods. The roller rods are distributed between the roller frame 8 and the inside of the laser cutting device 9, and the roller rods are staggered up and down, allowing the sheet material to pass through the pressing roller group for pressing and limiting.

[0032] In this embodiment, the waste bin 801 is movably connected between the roller frames 8. On the side of the laser cutting device 9 away from the roller frame 8, there is a blanking frame 10. At the bottom of the blanking frame 10, there is an upper support plate 1001, and on one side of the top of the blanking frame 10, there is a lower support plate 1002.

[0033] During use, the finished product is transported to the top of the blanking frame 10 through the conveyor belt of the laser cutting device 9, facilitating the staff to sort out the finished product. The cut waste sheet material can be placed in the waste bin 801 on one side of the roller frame 8 by the staff for collection.

[0034] In this embodiment, the lower support plate 1002 is fixedly connected to the outside of the laser cutting device 9. The lower support plate 1002 and the upper support plate 1001 are rotatably connected by a shaft rod. At the bottom of the blanking frame 10, there is a support rod 1003, and both ends of the support rod 1003 are inserted into one side of the lower support plate 1002 and the upper support plate 1001 respectively.

[0035] During use, when not in use, the staff lifts the blanking frame 10 to take the support rod 1003. The blanking frame 10 loses support and coincides with the lower support plate 1002, so that the blanking frame 10 is folded and stored on one side of the laser cutting device 9, avoiding the blanking frame 10 protruding and colliding with the staff, which affects the movement of the staff.

The sheet material cylinder 7 is placed on the roller frame 8. The staff pulls the sheet material through the pressing roller group 5 and places it in the clamping groove 101. The first pressing frame 2 and the second pressing frame 3 are started, and the air cylinder 202 drives the pressing plate 201 to descend to squeeze and fix the sheet material. When the sheet material is cut, the staff starts the cutting device 6 on one side of the clamping frame 1, and the electric push rod 602 drives the cutter 601 to cut off the tail of the sheet material, which is convenient for the staff to take the sheet material and facilitates the cutting of the sheet material, avoiding the pre-cutting from causing the sheet material to be wound and affecting the installation. The finished product is transported to the top of the blanking frame 10 through the conveyor belt of the laser cutting device 9, facilitating the staff to sort out the finished product. The cut waste sheet material can be placed in the waste bin 801 on one side of the roller frame 8 by the staff for collection. When not in use, the staff lifts the blanking frame 10 to take the support rod 1003. The blanking frame 10 loses support and coincides with the lower support plate 1002, so that the blanking frame 10 is folded and stored on one side of the laser cutting device 9, avoiding the blanking frame 10 protruding and colliding with the staff, which affects the movement of the staff.
