Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically a laser machine for cutting the size of inflatable ornaments. Background Technology

[0002] Inflatable ornaments are widely used in daily life and commercial activities due to their advantages such as being lightweight, having diverse shapes, and being inexpensive. These ornaments are usually made of flexible film materials such as PVC and TPU, and an important step in their production process is cutting the raw materials or semi-finished products according to the design dimensions.

[0003] In existing technologies, the following technical challenges are mainly encountered when cutting inflatable ornaments or their raw material films to size, especially when it is necessary to cut the outline around an existing three-dimensional shape:

[0004] Difficulty in securing the inflatable ornaments leads to poor cutting accuracy: Inflatable ornaments are inherently soft, easily deformable, and often have irregular curved surfaces, while the flexible film material to be cut is also prone to slipping or wrinkling. Traditional securing methods struggle to stably and damage both the inflatable ornament and the flexible material beneath it simultaneously. Excessive clamping pressure may crush or damage the inflatable ornament, while insufficient pressure or poor suction cup adhesion fails to effectively prevent material displacement and wrinkling during the cutting process. This directly results in laser cutting path deviation, inaccurate cutting contours, and a large number of defective products, severely impacting product quality and production efficiency.

[0005] Low efficiency and poor flexibility in cutting complex contours: For scenarios requiring 360-degree or complex curved contour cutting around inflatable ornaments, existing laser cutting equipment typically employs the following two methods:

[0006] Moving laser head / moving platform: This method tracks the cutting path by driving the laser cutting head or moving worktable to move in a plane through multi-axis linkage. However, this method cannot efficiently achieve continuous rotational cutting around a fixed center point. For circular or annular paths, frequent starts, stops, and direction changes are required, resulting in complex path planning, limited cutting speed, and bulky and expensive equipment.

[0007] Manually assisted rotation: Operators manually rotate the inflatable ornament in conjunction with a fixed laser head for cutting. This method heavily relies on operator skill, results in uneven rotation speeds, difficulty in guaranteeing positioning accuracy, poses safety hazards, and cannot achieve automated continuous production.

[0008] Therefore, there is an urgent need for a laser device specifically designed for cutting inflatable ornaments, which can effectively solve the dual stability and fixation problems of three-dimensional curved ornaments and flexible membrane materials during the cutting process, and provide a highly efficient, precise, and automated ability to rotate and cut complex contours around a fixed point, so as to meet the urgent needs of the inflatable ornament industry for high-precision, high-efficiency, and automated production.

The baffle is fixedly connected to the side of the cutting base away from the first electric push rod. The side of the cutting base near the baffle has a first sliding groove, and the laser cutting blade is slidably disposed in the first sliding groove.

[0014] Preferably, a first rotating groove is provided at the axis of the cutting base, the limiting rod is rotatably connected to the first rotating groove, a first annular groove is provided on the outer circular surface of the first rotating groove, a driving base is fixedly connected to the outer circular surface of the limiting rod, a second rotating groove is provided on the driving base, a driving shaft is rotatably connected to the second rotating groove, and a driving wheel is fixedly connected to the outer circular surface of the driving shaft.

[0018] (III) Beneficial Effects

[0019] This invention provides a laser cutting machine for inflatable jewelry. It has the following advantages:

[0020] 1. This solution uses a limiting suction cup to adhere and fix the inflatable ornament and a lifting pad to lift and press the raw material to be cut from bottom to top. This allows the inflatable ornament and the raw material to be cut below to be doubly and stably clamped and fixed in the cutting area, thereby effectively preventing the material or ornament from shifting or wrinkling during the cutting process, and achieving the goal of ensuring the accuracy of the cutting outline.

[0021] 2. This solution uses the meshing / friction transmission between the drive wheel and the first annular slot on the cutting base to directly convert the rotational motion of the drive wheel into the rotational motion of the cutting base (along with the laser cutting blade and baffle) around the axis of the limiting rod. This allows the laser cutting blade to perform 360-degree or specific angle contour cutting around the fixed inflatable ornament, achieving the purpose of efficiently and flexibly completing the cutting of complex shapes.

[0027] This utility model embodiment provides a laser machine for cutting inflatable ornaments to the correct size, such as... Figure 1-4As shown, it includes an operating table 11, a transmission cavity 12, a rotating roller 13, a support frame 14, a first electric push rod 15, a cutting base 16, a first sliding groove 17, a laser cutting blade 18, a baffle 19, raw material to be cut 20, a first rotating groove 21, a limiting rod 22, a limiting suction cup 23, a first annular slot 24, a drive base 25, a second rotating groove 26, a drive shaft 27, a drive wheel 28, a second sliding groove 30, a second electric push rod 31, a second slider 32, and a lifting pad 33.

[0028] like Figure 1-4 As shown, the operating table 11 has a transmission cavity 12, and two rotating rollers 13 are rotatably arranged in the transmission cavity 12. The raw material 20 to be cut is wound around the outer surface of the rotating rollers 13. A support frame 14 is fixedly connected to the operating table 11, and a first electric push rod 15 is fixedly connected to the support frame 14. The first electric push rod 15 is fixedly connected to a limit rod 22, and the limit rod 22 is rotatably connected to a cutting component. A second sliding groove 30 is opened on both sides of the transmission cavity 12, and a platform component is slidably connected in the second sliding groove 30. A limit suction cup 23 is opened at the end of the limit rod 22 away from the first electric push rod 15. The limit suction cup 23 is spherical and is used to fix the inflatable ornament.

[0029] The cutting assembly includes a cutting base 16, a laser cutting blade 18, and a baffle 19. The baffle 19 is fixedly connected to the side of the cutting base 16 away from the first electric push rod 15. The side of the cutting base 16 near the baffle 19 has a first sliding groove 17, and the laser cutting blade 18 is slidably disposed in the first sliding groove 17.

[0030] A first rotating groove 21 is provided at the axis of the cutting base 16. A limiting rod 22 is rotatably connected to the first rotating groove 21. A first annular groove 24 is provided on the outer circular surface of the first rotating groove 21. A driving base 25 is fixedly connected to the outer circular surface of the limiting rod 22. A second rotating groove 26 is provided on the driving base 25. A driving shaft 27 is rotatably connected to the second rotating groove 26. A driving wheel 28 is fixedly connected to the outer circular surface of the driving shaft 27.

[0031] The platform components include a second electric push rod 31, a second slider 32, and a lifting pad 33. One end of the second electric push rod 31 is fixedly connected to one end face of the second sliding groove 30, and the other end of the second electric push rod 31 is fixedly connected to the second slider 32. The second slider 32 is slidably connected to the second sliding groove 30. The lifting pad 33 is fixedly connected to the second slider 32 and is positioned below the raw material 20 to be cut. The baffle 19 and the limiting rod 22 are positioned above the raw material 20 to be cut.

[0032] First, the operator installs the roll of material 20, which is to be cut (such as PVC or TPU film for inflatable ornaments) 20, onto the two rotating rollers 13 in the transmission cavity 12, ensuring that the material 20 is laid flat on the upper surface of the operating table 11.

[0033] Then, the second electric push rod 31 located in the second sliding groove 30 on both sides of the transmission cavity 12 is activated. The piston rod of the second electric push rod 31 extends and pushes the second slider 32, which is fixedly connected to it, to slide upward in the second sliding groove 30.

[0034] The lifting pad 33, which is fixedly connected to the second slider 32, rises synchronously, lifting and pressing the area of ​​the raw material 20 to be cut located directly below the limiting suction cup 23.

[0035] Then, the first electric push rod 15 on the support frame 14 is activated. The piston rod of the first electric push rod 15 extends downward, pushing the limit rod 22 fixedly connected to it to move downward.

[0036] The limiting suction cup 23 at the lower end of the limiting rod 22 descends until it comes into close contact with and adheres to the inflatable ornament placed on the raw material 20 to be cut. The limiting suction cup 23 generates negative pressure (which can be achieved by a built-in micro air pump or an external vacuum source) to firmly adhere and fix the inflatable ornament in the current position.

[0037] At this time, the raw material 20 to be cut is firmly clamped between the upper limiting suction cup 23 (indirectly pressed by the fixing ornament) and the lower lifting pad 33, forming a stable cutting operation area, effectively preventing the material from shifting or wrinkling during the cutting process.

[0038] Next, the laser cutting blade 18 is activated. The laser cutting blade 18 moves radially within the first sliding groove 17 on the cutting base 16 (approaching or moving away from the central axis of the limiting rod 22), and adjusts the laser focus to the precise position on the surface of the raw material 20 to be cut according to the preset cutting pattern or size.

[0039] Start the drive unit on the drive base 25. The drive unit drives the drive shaft 27 to rotate, and the drive wheel 28 on the drive shaft 27 rotates accordingly.

[0040] Once the laser cutting blade 18 has completed the cutting of the predetermined contour (e.g., around the edge of the ornament), the laser cutting blade 18 stops working and resets (moves back to its initial position in the first sliding groove 17), the drive device stops, and the cutting assembly stops rotating.

[0041] Since the drive wheel 28 contacts the first annular slot 24 on the outer surface of the first rotating groove 21 on the cutting base 16, the rotational motion of the drive wheel 28 is converted into the rotational motion of the cutting base 16 around the axis of the limiting rod 22. The cutting base 16 drives the laser cutting blade 18 and the baffle 19 on it to rotate around the fixed inflatable ornament.

[0042] During rotation, the laser cutting blade 18 emits a high-energy laser beam, precisely cutting the raw material 20 to be cut along a preset path (straight line, curve, or closed contour). The baffle 19 remains behind the laser cutting blade 18 (relative to the direction of rotation) throughout the cutting process, effectively blocking molten material, spatter, or smoke generated by laser cutting, protecting other components of the equipment and the operating environment.

[0043] Finally, close the negative pressure of the limiting suction cup 23 and release the cut inflatable ornament.

[0044] The first electric push rod 15 retracts the piston rod, causing the limit rod 22 and the limit suction cup 23 to lift upwards and leave the operating area.

[0045] The second electric push rod 31 retracts the piston rod, causing the second slider 32 and the lifting pad 33 to descend and reset, returning to the transmission cavity 12.

[0046] Operators can then safely remove the cut inflatable ornaments and clean or remove the waste material from the lifting pad 33.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
